Percutaneous sacral screw fixation is the mainstay of posterior pelvic ring fixation. This study quantifies the accuracy of fluoroscopic screw placement using post-operative CT scans and redefines the fluoroscopic safe zone using a mathematical calculation obtained from Inlet and outlet images. The authors hypothesized that a mathematical calculati...
Background:
Zone 2 sacral fractures account for 34% of sacral fractures with reported neurological deficit in 21-28% of patients. The purpose of this study was to examine the risk factors for neurological injury in zone 2 sacral fractures. The authors hypothesized that partially thread iliosacral screws did not increase incidence of neurologic inj...
Introduction:
Tibial plateau fractures are challenging to treat due to the high incidence of postoperative infections. Treating physicians should be aware of risk factors for postoperative infection in patients who undergo operative fixation.
Patients and methods:
A retrospective review was undertaken to identify all patients with tibial plateau...
Background:
The management of open fractures requires wound irrigation and débridement to remove contaminants, but the effectiveness of various pressures and solutions for irrigation remains controversial. We investigated the effects of castile soap versus normal saline irrigation delivered by means of high, low, or very low irrigation pressure....
Objectives:
Reamer-irrigator-aspirator (RIA) bone graft harvesting human femurs have resulted in spiral fractures. Recommendations/studies on safe RIA diameter are noncomprehensive/inconclusive. Our purpose was to develop an analytical model to predict % reduction in torsional strength after intramedullary oversize reaming (concentric or eccentric...
Recent published data have suggested successful union of subtalar and tibiotalar joints without formal debridement during tibiotalocalcaneal (TTC) fusion procedures. Although previous studies have reported on the importance of the proper guidewire starting point and trajectory to obtain appropriate hindfoot alignment for successful fusion, to our k...
Intra-articular screw perforation is a common complication of open reduction and internal fixation of proximal humerus fractures. The purpose of this study was to: 1) determine the sensitivity and specificity of the fluoroscopic images used to evaluate whether a screw tip has perforated into the gleno-humeral joint 2) determine the specific fluoros...
Objective
Identify risk to neurovascular structures around the knee with placement of skeletal traction pins.
Methods
Kirchner wires were inserted into cadaveric limbs followed by layer dissecting of each leg. Correlations between weight, height, BMI, and distance were determined after calculating the average distance with deviation between each a...
This cadaveric study evaluated the risk of injury to the superior gluteal nerve when a proximal incision site is used for insertion of an antegrade, reamed femoral intramedullary nail into the piriformis fossa. Based on prior anatomical studies, our hypothesis is that the use of a proximal incision site for intramedullary nail insertion will consis...
In managing complex proximal tibia fractures, several options are available to the treating surgeon. Closed management with or without external fixation, formal open reduction and internal fixation, and intramedullary nail fixation have been described in the literature. There is a lack of consensus regarding the optimal treatment method for complex...
Treatment of infected long bone fractures or nonunions requires stability for bony union, yet retained implants can lead to persistent infection. Antibiotic cement intramedullary nails, in addition to external fixation, are commonly used to deliver intramedullary antibiotics in infected long bone fractures and provide temporary stability. However,...
This research aimed to construct three-dimensional (3D) visible models of the superior mediastinum for anatomic study and surgical approaches to the superior mediastinum.
Sectional images of the superior mediastinum were acquired through the Chinese Visible Human Female (VCHF) database. One hundred eighty images of the superior mediastinum were imp...
For decades, the basic tenets of managing displaced femoral neck fractures have not changed, but the optimal treatment choice continues to be highly debated. The contemporary controversies associated with the treatment principles of displaced femoral neck fractures are distinct between young and old patients and are considered individually in this...
A technical benefit of the reamer-irrigator-aspirator (RIA) system (Synthes, Paoli, PA) is the ability to harvest large volumes (40-90 cm3) of autogenous bone graft. Early evaluations of this technique have reported few problems, all of which were attributed to technical error. This case series reviews 6 RIA-associated complications including 4 fra...
To the Editor:
We read with interest the December 2008 article by Belthur et al. [1] entitled “Bone Graft Harvest Using a New Intramedullary System.” The authors’ comparison of iliac crest bone graft harvesting to intramedullary collection with the Reamer/Irrigator/Aspirator (RIA) system (Synthes, Inc, West Chester, PA) is an important study compa...
We examined the incidence of heterotopic ossification (HO) in a consecutive series of total hip arthroplasties (THAs) performed with the so-called minimally invasive, 2-incision technique. Standard preoperative hip radiographs were used to grade the extent of degenerative arthritis, and comparable follow-up radiographs at 30 months after surgery we...
The prevalence of damage to the musculature surrounding the hip joint was assessed in a random selection of patients who had a unilateral primary total hip replacement with either the two-incision minimally invasive technique, the standard posterolateral approach, or the direct lateral approach. The musculature of the operated hip was compared with...
The subvastus surgical approach to total knee arthroplasty preserves the insertion of the vastus medialis tendon on the patella, thereby resulting in superior functional outcomes in the short term. This surgical approach was adapted to perform a consecutive series of primary uncemented total knees, without a thigh tourniquet, using a short-length i...
The complications and difficulty associated with the minimally invasive surgery (MIS) two-incision technique in total hip replacement have been well publicized. In this report, the authors describe a modified technique for primary total hip replacement, using two small incisions and no fluoroscopy during surgery. Instead, a stepwise approach and ad...
Laser reshaping using low laser energy levels was performed on the cartilage of ten porcine ears. The ears were examined up to 4 months after laser reshaping and the stability of the reshaping was assessed by photography and casts obtained from alginate impressions of the ears. The cartilage was also studied histologically in three animals at 3 wee...
We reviewed 79 patients with clinically suspected Wegener's granulomatosis (WG) diagnosed in Nottingham between 1990 and 1997. Fifty-three patients were confirmed as having WG. We describe the symptoms and signs, features of diagnostic significance, ANCA results, biopsy sites, histology, treatment and outcome in this group. Nasal symptoms and signs...
It is difficult to permanently alter the shape of cartilage in a controlled way. In otolaryngology and plastic surgery several procedures are done to alter the shape of cartilage, for example the correction of a deviated nasal septum and surgery for bat ears. The aim of this paper is to study the main parameters which are necessary for the phenomen...
The dynamics of light scattering and internal force in cartilage are studied in the course of laser shaping. In vitro experiments were used for study the samples of human cartilage which were collected from patients who underwent nasal septum surgery.
We found that the dynamic of scattered light intensity depends on heating rate and on the temperat...
The problem of a purposeful change of the shape of cartilage is of great importance for otolaryngology, orthopaedics, and plastic surgery. In 1992 we have found a possibility of controlled shaping of cartilage under moderate laser heating. This paper presents new results in studies of that phenomenon. We have measured temperature and stress in a ti...
Considerable variations are present in the thickness of the normal nasal septum. These were studied and measured in cadavers and from MRI scans. In addition, a histological analysis was performed to determine whether cavernous tissue is present at any point in the septum. The nasal septum reaches maximum thickness antero-superiorly where the mucosa...
