It is extremely unfortunate that still paediatric orthopaedic facilities are under developed at least in my country.

As per the recently released SCIMAGO journal's rankings for 2023 (Journal Rankings on Orthopedics and Sports Medicine (scimagojr.com), there are 320 journals in the list of Orthopedics and Sports Medicine, with the top 10 are presented here.
Four Indian journals have featured in this list: Journal of Orthopaedics (#121), Journal of Clinical Orthopaedics and Trauma (#132), Indian Journal of Orthopaedics (#173), and Journal of Arthroscopy and Joint Diseases (#255).
Relevant answer
Answer
It's interesting to see the SCIMAGO journal rankings for Orthopedics and Sports Medicine for 2023 and note the representation of Indian journals within this list. While it's notable that four Indian journals have made it onto the list, their positions within the ranking provide insight into their perceived impact and influence within the field compared to other international journals.
The fact that the highest-ranked Indian journal, the Journal of Orthopaedics, is positioned at #121 indicates that it is recognized for its contributions but may not yet have achieved the same level of global prominence as some of the top-ranked journals. However, being ranked within the top 200 or 300 journals in a specific field still demonstrates credibility and relevance within the academic community.
For Indian researchers and practitioners in the field of orthopedics and sports medicine, these rankings can serve as a reference point for identifying reputable journals for publication and staying updated on the latest research and developments. Additionally, it highlights areas where Indian journals may seek to improve and compete more effectively on a global scale, potentially through collaborations, increased visibility, or enhancing the quality and impact of their publications.
Overall, the inclusion of Indian journals in the SCIMAGO rankings reflects the diversity and contributions of researchers and practitioners from around the world to the field of orthopedics and sports medicine, and it's encouraging to see the representation and recognition of Indian scholarship within this domain.

Hello there!
I am performing a systematic review regarding the effect of a specific surgical procedure on a common orthopaedic condition. All identified studies are case-series with no control group.
For these studies the outcome is pre- vs post-surgery change in Visual Analogue Scale (VAS).
Is it possible to perform a meta-analysis of pre- vs post-surgery change in VAS given there is no control group?
Any thoughts would be greatly appreciated!
Relevant answer
Answer
In my practice, I’ve been able to perform meta-analysis of pre/post op PROM scores in two manners:
1. Performing a pairwise meta-analysis of the continuous data, taking the preop score as one “arm” and the postop scores as the other “arm”.
2. Using the formulae for subtracting means and standard deviations listed in the cochrane handbook to caluclate the difference in pre/postop scores and performing a single-arm meta-analysis of the change value.
Method 1 would be preferrable if you are unable to access software such as RStudio or STATA, as it can be done on Revman.

For my dissertation I'm validating the method of sonication culture for prosthetic joint Infections and orthopaedic implant infection. Hopefully this method can be used in our lab since this has been repeatedly proved to be more specific than tissue culture. I want to investigate if this sonication method will also be beneficial for detecting osteomyelitis. In the literature there is not much to find on this subject, maybe researchers here can help me with the question if this is possible or maybe there are labs who already use this method?
Relevant answer
Jana van Wijngaarden Welcome! The sonication of bone fragments is not a valid technique. The implants provide a massive amount of biofilm, the best way to survive in a hostile environment. The other manner to evade the immune system is surviving into the osteoblasts, as Staphylococcus aureus does. It reduces osteoblast activity and may cause osteoblast necrosis. Therefore, sonicating bone fragments could not be helpful; this method can not release S. aureus from osteoblasts. Finally, vortexing (a stage of sonication method) cells can lead to mechanical shearing of the DNA. On the other hand, low-intensity pulsed ultrasound (< 5MHz) is helpful for fracture healing - the frequency for implant-related infection diagnosis purposes is 40±2 kHz.

Respected Fellows,
First and foremost, wish you all, all the very best for the year 2021!.
I was formerly a faculty member in Canada (2006-2011, Assistant Prof.), then came back to my mother-land. What I've seen in the past 10 yrs, in regard to publishing our papers, was that politics was GREATLY involved in numerous journals' decision on our manuscripts.
My question for you is as follows:
Do you agree that politics is involved in science these days?, and if so, should we, researchers, be indifferent with respect to unfair behavior of some of our fellows with respect to some others who are working in some countries, like my mother-land?.
Most recently, a manuscript from my research team, which was submitted to a Japanese journal, and it was 100% theoretical work, with no experiments involved at all, was rejected since one of the reviewers has criticized our work and mentioned why different steps of the experiment done in our work were not clearly explained (?!!!!!!). We immediately prepared a rebuttal and appealed their decision, but EIC has responded and mentioned we only accept about 10% of the manuscripts we receive (!!!!).

Does the term "contrast bath" imply any random time-temperature combination of hot and cold water or it is a specific combination of repetitive alternate spells of dipping the affected body part in cold water at a specific temperature for a specified duration followed by dipping in hot water at a specific temperature for a specified duration?
Relevant answer
Answer
Dear Mr. Shanker Lal, I largely agree with the earlier responders. A contrast bath is the immersion of the extremity under consideration alternatively (for a minute or two) in hot and cold bath for at least 15 min per sitting. Though the literature suggests water in cold container to be between 10-15 degrees C and water in hot container to be between 35-45 degrees C, it may be kept at the tolerance level of the individual.

After the ORIF surgery of right hand wrist fracture, the fingers are stiffened - the finger segments getting as hard as stones (hardened edema) - making the bending of fingers to close the palm as fist almost impossible as the stone hard lower segment of the finger doesn't allow the finger to be bent downwards. The physiotherapist tries mobiisation applying his full might to bend the fingers downwards causing extreme pain to the patient, still the fingers do not bend beyond 90 degrees from their fully stretched position. Is this physiontherapy (extreme torture to the patient) - extending to 2 / 3 / 4 weeks or even more - the only way to restore the fingure movement or there are some easier / painless patient-friendly ways (such as some medication etc.) of treating the stiffened fingers without subjecting the patient to ubearable tortures?
Relevant answer
Answer
There may be various reasons for stiff fingers following wrist surgeries such as lack of occupational therapy and complex regional pain syndrome (reflex sympathetic dystrophy syndrome) . Best option is to start graded occupational therapy combined with wax therapy . If the stiff ness associated with pain ,then always need to suspect CRPS. so treat accordingly with various measures including drugs and therapy. It would be a long course to get normal functional hand.

What is the course of action in an arthroplasty which is infected clinically but is culture negative? I find this a difficult situation in many orthopaedic infections not only arthroplasty where the clinical features from a weeping wound to local signs cry infection and even the deeper swabs grow nothing. How does one tailor the antibiotics in such situations?

Negative culture results weren’t really terrible
One-stage revision arthroplasty demonstrated similar outcomes including reinfection, re-revision, and readmission rates for the treatment of chronic culture-negative PJI after TKA and THA compared to two-stage revision (van den Kieboom J, . One-stage revision is as effective as two-stage revision for chronic culture-negative periprosthetic joint infection after total hip and knee arthroplasty. Bone Joint J. 2021 Mar;103-B(3):515-521. )

The COVID pandemic has been a blessing for most journals, including our Journal of Clinical Orthopaedics and Trauma. Currently, we are getting around 6 new manuscripts daily and the number of submissions in the last 4 months has risen to 280%, compared to the last year. I do not know when this curve is likely to flatten to come to normalcy.
This trend has over-burdened the editors and their editorial team members, especially as the number of journal staff has not risen but has actually decreased to lockdown and some staff getting sick.
What are the likely reasons for such an exponential rise?
Relevant answer
Answer
We all know hospitals have been busy, but many depoartments such as orthopaedics have seen a fall off in major trauma (up to at least a third) in some departments, clinics have been closed or made virtual, some doctors have been redeployed. I think however there has been space for some doctors to write many papers. Certainly from my old department a number of helpful long term patient reported outcome studies (PROMS) have appeared and are in press. Partly this is due to COVID-19.
As a regular reviewer for sugical journals I have seen a surge in paper writing in the last year and often I get about one paper a day to review! Unfortunately the quality of some papers has significantly fallen and there is a lot of replication of very similar studies. I would caution all writers of "new papers" to carefully check the literature on what has already been written, If you don't have a significant new message I'm afraid you won't get published.

Answer
In most of my cases I use a non-cemented stem without a collar, but I think that the use of the collar depends on the type of stem, if a wagner-type stem is used, the collar makes more sense than a wedge like the Corail where part of the success is the pressure fit when resting on the impacted spongy bone.

Whilst we are awaiting evidence of all types, what is the best current evidence for orthopaedic robots?
In the future, there are many possible study designs and outcome measures. Medical device research is confounded by the inability to blind the surgeon and the varied surgical technique. Registry data may give the answer in the long term but is likely to be confounded by experienced surgeons using the robot and fit patients selecting the robot.
Is the best outcome measure 3D CT measured implant position of robotic vs human ?
Relevant answer
Answer
I attended a demonstration of Stryker's arthroplasty robot (Mako), which is currently being introduced in the UK via private healthcare companies (BMI). I discussed theatre aspects of this approach and whilst the surgery duration has not changed between standard or robotic approach, the incisions are small and patients that were available to talk to on the day had reported a shorter length of stay and improved outcomes. The use of CT imaging as a guide during surgery I found particularly interesting as Surgeons are able to take templating one step further and account for all types of structural differences and by using the robot this can be precision cutting.

Hi,
What I understood is that an upper-knee amputation post infection + life threatening medical assistance + multiple sequential amputations caused a fat embolism.
I meant that in post-infected ans scared tissues with possible weak veins, it is hazardous to restrict the embolism entry to the shaft marrow since is seems there was no material pushed inside in the bone shaft; such insertions may cause fat embolism.
For upper knee amputation, by definition, we loose a lot of weight, which is changing the remaining thigh balance in the side coronal plane, since the femoral offset is not changed. Too much correction has consequences for sure.
Soft tissues tend to "melt" very quickly. Then we tend not to strip muscles (they will turn into fat) and fat regarding the bevel bone cut. And in fragile tissues, it is important not to have too tight tractions one the skin causes by the stitches. It may cause succion troubles in the prosthesis but it is another problem.
Talking about shoes, a bare foot has a lot of fat pad regarding metatarsian heads and ever stronger shell at the heel (very useful in Syme's amputation).
Cheers, JM.

I always give analgesia like buprenorphine just before surgery and than morning/evening for three days post-surgery. That has worked very well in Nude rats. But normal mice even need less analgesia. You are giving antibiotics before and post-surgery. May be you should include some analgesia also. Swelling first day, I will be of some concerned but can not do much and will wait for 2/3 days, hope that will be go down. If any internal suture has not broken, sometime it can happen also. If veterinarian around, you should address this question to him/her. And watch your mouse morning /evening for few days regularly. Mice in general heal faster than other animals like rabbit.

In today's era of orthopaedics, PSI helps in performing the replacement surgery more accurately with reproducible results. The literature supports the usage of PSI with numerous benefits.
Market has numerous options of PSI - few being MRI based, while others CT based. What is your take on this technology and which one do you prefer, if any?
Relevant answer
Answer
There are two main goals from the imaging. The first is to calculate the optimal alignment for the replacement and the second is to produce cutting blocks which are accurate and easy to use intra-operatively. CT is better for quick analysis of bone contours and therefore alignment whilst MRI can give images which facilitate the production of better jigs - as they can incorporate cartilage and soft tissue. You could argue that as both are non weight-bearing, neither can actually measure physiological alignment. S&N Visionaire is likely one of the most popular and uses combined MRI and full leg X-Ray to design cutting blocks specific to that patient.

Answer
I agree with the comments above made by the esteemed faculty. My personal view is that there is no alternative of a skilled and well trained surgeron. Core skills are required to use ribots and computer aided procedures. COAS is being used and is most helpful in complicated cases where patient specific implants are required so one can have 3D reconstruction of comlex anatomy that will help in manufacturing pre operatively and positioning of the implant during surgery.Robots are useful and are thought to be the future but in my view as an adjunct however but a lot of more work is being done for precision, easy to use and cost effectiveness.

Often overlooked, these occur most commonly among women, whose works involve sewing, washing, and cooking, Dr Maharjan explains.
“It looks like a sac of liquid or a cyst and located just under the skin,” informs the doctor. Adding that the treatment largely involves resting, Maharjan said the main cause is due to excessive movement and pressure of the limbs.
“Especially women while doing household activities, there’s a lack of fine movement of hands. It is strenuous and helps grow cysts on the hand,” The doctor also observed that it is the highest among women between 20 and 40.

The cannulated screws are a great teaching tool for residents and inexperienced surgeons to cause less mistakes and redrilling. Whether a screw is cannulated or not you have to clear the tissues so the bone is exposed for the drill and screw insertion. In the hands of an experienced surgeon they can insert a solid screw any place a cannulated screw can be used. Solid screws are stronger and cannulated screws cost 8-10 times their solid counterparts.

Dear collegues 
In our practices we often see patients with neurological complaints. At those moments it is important to test the neurological system as good as possible. And we do so by using the techniques we were taught. When it comes to neurological tests in the upper limb we all know the tests of which Wilhelm Heinrich Erb was the founder. They state that when you test nervus ulnaris, nervus radialis and nervus medianus, the patient is in a supine position and the therapist induces the respective movements to create a maximal tension on the nerve. Now I am wondering: ‘Why is it in a supine position and not in a sitting position?’ Is there a specific reason why the test is developed and taught like this? Because personally I think it is possible to test in a sitting position. Is there any known research on this topic? Or does anyone of you have advice in this area? Are there other approaches, or only variations of the technique above?

In leg amputation the remained bone is rasped to make the edges smoother to avoid tissue injuries. but still there is an unusual structure underneath the skin. 
Why don’t we use an implantable structure to avoid abnormal structure like sharp edges and damp the undue pressure and shocks underneath bones, the same way heel fat pad*(HFP) protects the underlying structures in the heel?
From my point of view, using such implants might also ease the use of prosthetic legs and decrease the possible pain in leg- prosthetic interfaces.
Are there any specific reasons not to use such implants during the leg amputation?
*The heel fat pad (HFP) is a highly specialized adipose-based structure that protects the rear foot and the lower extremities from the stress generated during the heel-strike and the initial support phase of locomotion. HFP cushioning efficiency is the result of its structure, shape and thickness.
Relevant answer
Answer
Bevelled bone end + adequate thickness of myoplasty should do the trick. Implant on the bone end is not necessary especially if the prosthesis is not designed to receive weight transmission through the end stump. If we worry about bad soft tissue surrounding the bone end, putting an implant on that area will create more problems, such as rapid implant wear, infections. Higher amputation level with good soft tissue should be put into consideration.

since the drill are made of plastic,it is possible for them to be completely sterilized? and they are packed in bags that are also plastic.
Relevant answer
Answer
Many less developed world hospitals use commercial " hardware" drill for orthopaedic surgery; usually wrapped in a sterile drape, although this clearly somewhat compromises sterility. The problem is that dedicated, sterilisable battery or pneumatic drills / saws are prohibitively expensive and "hand drilling" is difficult and takes time. Arbutus medical ( http://arbutusmedical.ca ) now produce sterilisable, reusable drill and saw bags. The drill bag uses a bayonet fitting to a De Walt drill that can be bought at hardware stores for as little as $100.

Actually, austenitic SSs have become less used. A certain % of people react badly to the Ni in grades like 316.  Ti alloys, nitinol and Co-based alloys (hip implants) have become more popular. MSSs have too high a modulus of elasticity, likewise the ASSs. The Ti alloys have a lower modulus of elasticity and weigh less, which is a better balance to bone. They have good corrosion resistance in the body.

Please, what can you say about the precision of 3D-printed patient-specific orthopedic surgical guides?
How is its precision impacted during these processes:
- Imaging of the bone model
- Preoperative planning with the imaging
- Manufacturing of the guides
- During surgical operation
- Other processes
Thank you. 
Relevant answer
Answer
This is something I've spent a considerable amount of time investigating. Our team has developed surgical planning software for various procedures and have looked at all of these issues.
- Imaging of the bone model: This is very accurate using CT scanners (and MRI). You can obtain CT scans of a human down to 0.2mm or less voxel spacing (meaning a density sample every 0.2mm in 3D space) on standard medical CT scanners and have error tolerances less then than when compared against actual measurements. The important thing here is to choose a resolution that makes sense for the problem and also minimizing the radiation dosage to the patient. Patient movement and a poor rad technician can also play a role here.
- Preoperative planning with the imaging: there are two main parts to consider here, the software itself and the operator. Most surgical planning software if designed properly will have nearly zero error on top of the error inherent in the data operated upon. This can be validated by comparing measurements on input versus output data from the software. The error in pre-surgical planning comes mainly from the clinical operator of the software. It is important to perform intra- and inter-operator studies to understand the variation among operators due to human variations. This can be very high, several millimeters (or degrees if angles are important), and can also simply be completely wrong due to a major human error. The key here is developing a precise and easy to follow procedure to train and guide operators when using the software. It is also a good idea to perform some sanity check at the end to validate some basic assumptions about the output. For example, if a set of points should have symmetric counter parts, software can be added to automatically evaluate symmetry prior to output -- or a surgical guide could be evaluated to determine if it may interfere with other bone regions.
- Manufacturing of the guides: this is also very accurate. This depends upon the mode used, additive printing or CNC manufacturing for example. CNC is ultimately more accurate I believe, down to 0.001mm or better and some 3D printing technologies are close to that.
- During surgical operation: many factors play a role at this stage. However, the ease of use of the surgical guide can greatly affect error at this stage. The guide itself should be designed such that it only fits in a single position. Consider a guide that sits upon a large flat region versus one that fits into the nooks and crannies of an orbital rim. Bony features are required to constrain the 3D placement of the guide in 3D space, you need to have all three directions locked down by some feature. If you don't the surgeon will have a great deal of trouble aligning the guide. Further, there should be visual cues engraved onto the guide to further eliminate error, such as: patient name, patient ID, manufacture date, LEFT/RIGHT, anatomic directions guiding placement, etc. The surgeon needs to be able to pick the guide up without ever seeing it before and know exactly how it goes into place. There are also issues with how the guide sits upon the surface. For example, there could be cartilage that did not appear in the CT scan that blocks final placement of the guide. The surgeon then needs to scrape this away before placing the guide.
- Other issues: the guide is for drilling or cutting, so what comes after that? Placement of a prosthetic or construction of a mandible? There can be additional significant error sources here as well.
We were involved in some cadaver studies that measured the final placement of  total-knee prosthetics using our surgical guides and we obtained less then 0.5mm and 0.5 degrees of variation for the final prosthetic from our intended plan for several cadavers as measured from a post-operative CT -- this is considered significantly better than the current standard or care.
If it's not clear, the main source of error is human. So, study each step and determine where humans are involved and either minimize or eliminate them from the step or provide clear guidance to create a repeatable and robust process.
We provide some software that can be used to perform 3D measurements based upon landmark points. This software, Checkpoint can load DICOM data, render it in 3D, provides tools for landmark placement and measurement of lengths and angles among a variety of other things. This can be used to quantitate error at the various stages.

What type of replacement will allow hip to continue such activities for as long as possible, with as few revisions as possible. 
Relevant answer
Answer
This is a very difficult question аnd not clear enough. Do you mean inflammation of the joint(osteoarthritis) or degeneration of the joint (osteoarthrosis )?               Anyway, the requirements for longevity and activity seem to me to be very high. In fact, every replacement surgeon strives to secure such excellent outcome results on a long-term basis. Based on my practice, I would also recommend cementless total endoprosthesis (highly crosed linked poly and ceramic femoral head with porous coated stem). In average, 92-93% of the implants do well in a 10-year period. Thereafter, the revision rate slowly increases. Just one more issue to be kept in mind:  big loads on the THR may lead to an earlier loosening and exchange.  As far as the implant models recommended are considered, you may have a look at The Swedish Hip Registry which gives  precise and actual data on the prosthesis survivorship almost every year.

If computer assistance (CAOS) is available, you can operate both knees without removing the nails. If not, I suggest removing the nails. The screws in the right femur may remain in place. The left knee seems easy, but the right knee is a challenge: Take a true anterior-posterior long hip-knee-ankle x-ray with a calibration object on it. Imagine were you can place the intramedullary rod. Measure the distance from the entry point to the point where the rod will abut on the lateral cortex of the femur. Measure the HKFS-angle (hip-knee-intramedullary rod angle). Then ask your supplier or technician to deliver an intramedullary rod that is not too long. Finally, during the operation, set the distal cut at the HKFS-angle you already measured on the x-ray. The rest should be like a standard procedure.

The discoid meniscus is common in East Asian (10-13%) than in Western World (3-5%). In China, it’s very common and routinely being operated (arthroscopic partial meniscectomy-saucerization). It is not that uncommon to see discoid meniscus during TKA as incidence is high, but exact frequency is not known. Most of the discoid gets injured as patients get older due to the degenerative changes of both the meniscus and the bone, and even simple activities predispose to discoid meniscus injury.

There is no international institute or committee that 'regulates'  or ' provide general structured models.... of surgical procedures'.
Most textbooks and academic journals on technique present a logically structured and organised approach to procedures. These are not standardised. There would be variations in technique, justified by authors, for various clinical reasons, as appropriate.
Most surgical procedures have multiple approaches and techniques, as described in journals and textbooks. These vary in different institutions, and geographically.
Also, technology is changing procedures, and a structure appropriate at one point in time, would be inappropriate with a change in this area. This allows for innovation and advancements in surgery.

I note that there is a distal lesion at the bottom of your x-ray.  I have managed these kinds of fractures.  The plate does not need to be very long.  Determine the size of the diaphyseal lesion.  If it is an impending fracture, simply place the and then place a retrograde nail up the femur.  The plate screws can be used to lock the nail.  You most recognize that the primary object is to NOT fracture the bone any further, as doing so would get into a lot of bleeding.  You must have a well-thought-out plan before you start.  Alternatively, you can watch the distal lesion if it does NOT meet the need for prophylactic stabilization.  The key is to use the contralateral hip as a template for the angle and proper placement for the plate on the fractured side.  Please note how thick the cortex is.  A substantial amount of reaming would be required to drop the nail.  Noe of which wold be beneficial to the patient.

Answer
There are many variables depending on the type of printer but typically the costs of 3D printing include cost of technician, material used in the printing process, and wear/tear on the machine. The material probably equates to the majority of the costs and can be significantly reduced if a hollow object can be made.
To give a perspective, the in-house cost to print something like a hollow scapula would be around $50-75. This same build could easily be 3-400 if out-sourcing and more if purchasing through second-hand party.
