    ABSTRACT: Background: Scoliosis is a complex three-dimensional deformity of the spine, which usually occurs during childhood and adolescence. Up to now, whole spine X-rays have been the therapeutic gold standard in the diagnosis and follow-up of scoliosis. Aim: This review gives a brief overview of the history, technical background and possible fields of use for video-rasterstereography METHODS: Alternative measurement systems have been developed over the past few years for the treatment of scoliosis, because of the risk of radiation exposure of X-rays. The rasterstereographic system Formetric (Diers International GmbH, Schlagenbad) allows a radiation-free, three-dimensional analysis of the back surface and the spine. Outlook: Even dynamic measurements can now be conducted with this rasterstereographic system, which will help to further understand and analyze the human spine.

    ABSTRACT: Scoliosis is a complex, three-dimensional spinal deformity with various causes. Adolescent idiopathic scoliosis (AIS) is the most common form. Surgical treatment is indicated for curves greater than 45-50° meaured using the Cobb method. We can distinguish among posterior, anterior or combined surgical procedures. Today, the posterior, transpedicular approach has revolutionized scoliosis surgery. This review gives an overview of current surgical options in scoliosis treatment.

    ABSTRACT: Scoliosis affects up to 6 % of the population. The resulting spine deformity, the increasing risk of back pain, cosmetic aspects, pulmonary disorders if the Cobb angle is > 80°, and the progress of the deformity to > 50° after the end of growth indicate non-operative or operative therapy. In daily clinical practice, the classifications of scoliosis allow the therapy to be adapted. Classifications consider deformity, topography of the scoliosis, and the age at diagnosis. This publication gives an overview of the relevant and most common classifications in the treatment of adolescent scoliosis. For evaluation, the deformity measurement on the coronary radiographic projection of the total spine (Cobb angle) is relevant to therapy. The classification of topography, form, and the sagittal profile of the deformity of the spine are useful for preoperative planning of the fusion level. Classifications that take into account the age at the time of the diagnosis of scoliosis differentiate among early onset scoliosis (younger than 10 years of age), adolescent scoliosis (up to the end of growth), and adult scoliosis. Early onset scoliosis is subdivided by age and etiology. Therapy is derived from the classification of clinical and radiological findings. Classifications that take into account clinical and radiological parameters are essential components of modern scoliosis therapy.

    ABSTRACT: Introduction: The aim of multidisciplinary rehabilitation after total knee replacement (TKA) is to reduce postoperative complications and costs and enable faster convalescence. The goals of fast-track rehabilitation, as a multidisciplinary concept, are to reduce the length of hospital stay and achieve early functional improvements by optimizing the perioperative setting. Method: A literature review was carried out for the years 1960-2013. The search terms were: "rehabilitation", "training", "physiotherapy", "physical therapy", "recovery", "exercise program", "knee surgery", "TKA", "total knee replacement", "arthroplasty", "intensive", "multidisciplinary", "accelerated", "rapid" or "fast track". Only randomized controlled trials and metaanalyses were included. A survey was also performed to assess care as actually offered in orthopaedic rehabilitation clinics in North Rhine-Westphalia. Results: A total of 729 articles were identified of which 11 studies were included. Fast-track rehabilitation can significantly reduce both the duration of hospital stay and costs after TKA. Current studies showed that a better short-/middle-term clinical outcome might be achieved with multidisciplinary rehabilitation. However, a difference in the long-term outcome could not be observed. Our survey shows that most patients are admitted to a rehabilitation clinic in a state of poor general condition as well as decreased mobility and knee range of motion. Conclusions: Fast-track rehabilitation facilitates a shortened hospital stay as well as cost saving. It probably can be used to optimize the condition of the patient before admission to a rehabilitation facility. © Georg Thieme Verlag KG Stuttgart · New York.

    ABSTRACT: Loss of articular cartilage surface integrity is considered the earliest sign of osteoarthritis; however, its reliable detection has not been established by clinical routine diagnostics. This study comprehensively assesses a set of 11 algorithm-based 2-D Optical Coherence Tomography roughness parameters and investigates their clinical impact. Histology and manual irregularity quantification of 105 human cartilage samples with variable degeneration served as reference. The majority of parameters revealed a close-to-linear correlation with the entire spectrum of degeneration. Surface integrity should therefore be assessed by a combination of parameters to improve current diagnostic accuracy in the determination of cartilage degeneration.

    ABSTRACT: Morphologically, bone marrow edema (BME) is an accumulation of fluid in the bone marrow. The BME is per se non-specific but can be identified at an early stage with magnetic resonance imaging (MRI). The underlying pathomechanism remains unclear. The BME can occur as an individual entity and as an accompanying condition of many diseases. The BME can be divided into three groups, ischemic, reactive and mechanical BME. Mechanical BME occurs after trauma or repetitive strain. Typical histological changes are present and there is no clear boundary between edema and microfracture. Some forms of trauma show BME in typical localizations. Both the trauma and the possible accompanying injuries can be indirectly indicated in this way in cases with an unknown trauma mechanism. The BME can be present as an isolated entity or as a comorbidity. For initiation of therapy, a comprehensive medical history and targeted diagnostics are indispensable. In some cases BME is indicative of the trauma mechanism and possible further accompanying injuries.

    ABSTRACT: The purpose of this study was to examine the spinal posture in young athletes depending on training intensity. The spinal curvature of 245 children, age 8 to 12 years, was evaluated using rasterstereography. According to their weekly training time group 1 (mean age: 9.54 ± 1.18) did 2-6, group 2 (mean age: 9.49 ± 0.87) did 6-15 and group 3 (mean age: 9.68 ± 0.87) did over 15 hours of training. Group 1 had a significantly higher weight (p = 0.028) (33.86 ± 7. kg) than those of the more active groups (30.67 ± 6.49 kg and 29.46 ± 4.33 kg). The mean kyphotic angle decreased significantly (p < 0.001) with the amount of training per week from 46.86 ± 8.2° in group 1 to 40.08 ± 8° in group 3. We also found a significant decrease (p = 0.047) in lateral deviation with training from group 1 with 5.3 ± 3 mm to group 2 with 4.1 ± 1.6 mm. The results of our study suggest that higher training time can be associated with lower weight and decreases in thoracic kyphosis and lateral deviation of the spine.

    ABSTRACT: IntroductionBesides the use of autologous bone grafting several osteoconductive and osteoinductive methods have been reported to improve bone healing. However, persistent non-union occurs in a considerable number of cases and compromised angiogenesisis suspectedto impede bone regeneration. Hyperbaric oxygen therapy (HBO) improvesangiogenesis. This study evaluates the effects of HBO on bone defects treated with autologous bone grafting in a bone defect model in rabbits.Materials and Methods Twenty-four New-Zealand White Rabbits were subjected to a unilateral critical sized diaphyseal radius bone defect and treated with autologous cancellous bone transplantation. The study groups were exposed to an additional HBO treatment regimen. Bone regeneration was evaluated radiologicallyand histologically at 3 and 6 weeks, angiogenesis was assessed by immunohistochemistry at 3 and 6 weeks.ResultsThe additional administration of HBO resulted in a significantly increased new bone formation and angiogenesis compared to the sole treatment with autologous bone grafting. These results were apparent after 3 and 6 weeks of treatment.Conclusion The additionof HBO therapytoautologousbonegraftsleadstosignificantlyimprovedboneregeneration. The increase in angiogenesis observed could play a crucial role for the results observed. This article is protected by copyright. All rights reserved

    ABSTRACT: The Essex-Lopresti injury (ELI) of the forearm is a rare and serious condition which is often overlooked, leading to a poor outcome. The purpose of this retrospective case study was to establish whether early surgery can give good medium-term results. From a group of 295 patients with a fracture of the radial head, 12 patients were diagnosed with ELI on MRI which confirmed injury to the interosseous membrane (IOM) and ligament (IOL). They were treated by reduction and temporary Kirschner (K)-wire stabilisation of the distal radioulnar joint (DRUJ). In addition, eight patients had a radial head replacement, and two a radial head reconstruction. All patients were examined clinically and radiologically 59 months (25 to 90) after surgery when the mean Mayo Modified Wrist Score (MMWS) was 88.4 (78 to 94), the mean Mayo Elbow Performance Scores (MEPS) 86.7 (77 to 95) and the mean disabilities of arm, shoulder and hand (DASH) score 20.5 (16 to 31): all of these indicate a good outcome. In case of a high index of suspicion for ELI in patients with a radial head fracture, we recommend the following: confirmation of IOM and IOL injury with an early MRI scan; early surgery with reduction and temporary K-wire stabilisation of the DRUJ; preservation of the radial head if at all possible or replacement if not, and functional bracing in supination. This will increase the prospect of a good result, and avoid the complications of a missed diagnosis and the difficulties of late treatment. Cite this article: Bone Joint J 2014;96-B:1385-91.

    ABSTRACT: Degeneration of the atlanto-dens and atlanto-axial joints is associated with cervical spine pain and may also be associated with an increased risk of dens fracture. However, there is paucity of literature describing the prevalence of specific degenerative changes in the atlanto-dens and atlanto-axial facet joints.

    ABSTRACT: Purpose Despite the high prevalence of low back pain during pregnancy there is still a lack in the understanding of its aetiology. Changes of the spinal posture due to the anatomical changes of the pregnant body seem to be in part responsible for the back pain. In this pilot study we assessed the potential to accurately measure the spinal posture and pelvic position during pregnancy without any harmful radiation using a spine and surface topography system. Methods Thirteen pregnant women were examined during the second and third trimester of their pregnancy, and postpartum. Twenty female, non-pregnant volunteers comprised the control group. The spinal posture and pelvic position were measured with a radiation-free spine and surface topography system. Results We found a significant increase in thoracic kyphosis during the course of pregnancy, but no increased lumbar lordosis. The lateral deviation of the spine also decreased significantly. However, we did not measure significant changes of the pelvic position during or after pregnancy. Conclusions The results of our study show that pregnancy has an effect on the spinal posture, and that spine and surface topography can be used to measure these changes three-dimensionally and without any harmful radiation. In future studies this technique could allow to further evaluate the relationship between posture and low back pain during pregnancy, helping to understand the aetiology of low back pain in pregnancy as well as to identify methods for its prevention and treatment.

    ABSTRACT: One possible alternative to the application of autologous bone grafts represents the use of autologous bone marrow concentrate (BMC). The purpose of our study was to evaluate the potency of autologous platelet-rich plasma (PRP) in combination with BMC. In 32 mini-pigs a metaphyseal critical-size defect was surgically created at the proximal tibia. The animals were allocated to four treatment groups of eight animals each (1. BMC+CPG group, 2. BMC+CPG+PRP group, 3. autograft group, 4. CPG group). In the BMC+CPG group the defect was filled with autologous BMC in combination with calcium phosphate granules (CPG), whereas in the BMC+CPG+PRP group the defect was filled with the composite of autologous BMC, CPG and autologous PRP. In the autograft group the defect was filled with autologous cancellous graft, whereas in the CPG group the defect was filled with CPG solely. After 6 weeks radiological and histomorphometrical analysis showed significantly more new bone formation in the BMC+CPG+PRP group compared to the BMC+CPG group and the CPG group. There were no significant differences between the BMC+CPG+PRP group and the autograft group. In the PRP platelets were enriched significantly about 4.7-fold compared to native blood. In BMC the count of mononuclear cells increased significantly (3.5-fold) compared to the bone marrow aspirate. This study demonstrates that the composite of BMC+CPG+PRP leads to a significantly higher bone regeneration of critical-size defects at the proximal tibia in mini-pigs than the use of BMC+CPG without PRP. Furthermore, within the limits of the present study the composite BMC+CPG+PRP represents a comparable alternative to autologous bone grafting.

    ABSTRACT: Systemic capillary leak syndrome is a rare and life threatening disease characterized by periodic episodes of hypovolemic shock due to leakage of plasma from the intravascular to the extravascular space. It is associated with hemoconcentration, hypoalbuminemia, and generalized edema. We report the case of a patient with idiopathic systemic capillary leak syndrome who developed an unexpected and potentially fatal abdominal and four-limb compartment syndrome. This was successfully treated with fasciotomies and medical treatment including terbutaline, theophylline, and corticosteroids. To the best of our knowledge this is the first report of this kind in the literature. Case presentation A previously healthy 54-year-old Caucasian man presented to the emergency department of our internal medicine ward with a medical history of aggravation of general health related to dizziness, weight gain, and two syncopal attacks. Due to a massive emission of fluids and proteins from the intravascular to the extracellular compartments, he developed compartment syndromes in his upper and lower limbs and the abdominal compartment. The abdomen and all four limbs required decompression by a fasciotomy of both forearms, both thighs, both lower legs, and the abdomen within 24 hours after admission. After 60 days of treatment he was dismissed from the clinic. He was able to return to his previous occupation and reached the same level of athletic activity as before the illness. Systemic capillary leak syndrome is a very rare disease that can lead to a fatal clinical outcome. It is important to be aware of the fatal complications that can be caused by this disease. Despite the fact that systemic capillary leak syndrome represents a very rare disease it is still important to be aware of life threatening complications, like compartment syndromes, which need surgical intervention. However, early diagnosis and interdisciplinary treatment can lead to a good clinical outcome.

    ABSTRACT: All available treatment options for osteochondral and chondral defects do not restore hyaline cartilage and are limited to decreasing associated pain, and maintaining or improving joint function. The purpose of this study was to evaluate the potential of erythropoietin (EPO) in combination with bone marrow aspiration concentrate (BMAC) in the treatment of osteochondral defects of mini-pigs. 14 Goettinger mini-pigs, in which a 6×10 mm osteochondral defect in the medial femoral condyle of both knee joints was created, were randomized into four groups: biphasic scaffold alone, scaffold with EPO, scaffold with BMAC and scaffold in combination with EPO and BMAC. After 26 weeks all animals were euthanized and histological slides were evaluated using a modified ÓDriscoll Score. In the therapy groups, areas of chondrogenic tissue that contained collagen II were present. Adding EPO (p = 0.245) or BMAC (p = 0.099) alone to the scaffold led to a non-significant increase in the score compared to the control group. However, the combination of EPO and BMAC in the implanted scaffold showed a significant improvement (p = 0.02) in the histological score. The results of our study show that in mini-pigs, the combination of EPO and BMAC leads to an enhanced osteochondral healing. However, additional research is necessary to further improve the repair tissue and to define the role of MSCs and EPO in cartilage repair.

    ABSTRACT: The purpose of this study was to investigate age differences in the response of the spine and pelvis to simulated leg length inequalities (LLIs). A total of 107 subjects, separated into three age groups (group 1: 20-39 years, group 2: 40-59 years, group 3: >60 years), were used to evaluate for any age effects in the response to LLIs. LLIs of +10, +20, and +30 mm were simulated with a simulation platform on both sides, and the respective changes of pelvic position (pelvic obliquity, pelvic torsion) and spinal posture (lateral deviation, surface rotation, kyphotic, and lordotic angles) were measured with a rasterstereographic system. In all three age groups an increase in LLI led to significant changes in the pelvic position as measured by the parameters of pelvic obliquity and torsion. No significant differences in the response of the pelvis to the LLIs were found between the age groups. In all age groups an increase in surface rotation and lateral deviation of the spine with increasing LLIs was found. However, none of these parameters responded significantly different between the three age groups. Under static conditions, LLIs lead to significant changes of the pelvic position and spinal posture. Despite all known age-related changes, no significant differences of the measured pelvic and spinal parameters in elderly patients as a response to the simulated LLIs occurred.

    ABSTRACT: This biomechanical study is the first to compare 3 fixation methods-bilateral fixed-angle plate, modified anterior tension wiring, and cannulated lag screws with anterior tension wiring-in multifragmentary distal patella fractures. A T-shaped 3-part fracture simulating a multifragmentary articular distal patella fracture (AO/OTA 34-C2.2) was created in 18 human cadaver knee specimens. Three groups were created using homogenous ages and bone mineral densities based on the fixation method received. Repetitive testing over 100 cycles was performed by moving the knee against gravity from 90° flexion to full extension. Failure was defined as fracture displacement greater than 2 mm. In all patellae using fixed-angle plates, an anatomical fracture reduction could be maintained throughout cyclic testing, whereas anterior tension wiring and lag screws with tension wiring showed significant fracture displacement after 100 cycles, with mean fracture gaps of 2.0±1.3 and 1.9±1.6 mm, respectively. The differences in fracture gaps between the fixed-angle plate group and the other 2 groups were statistically significant. In both groups using tension wiring, half of the constructs (3 of 6 in each group) failed due to a fracture displacement greater than 2 mm. The bilateral fixed-angle plate was the only fixation method that sustainably stabilized a multifragmentary articular distal patella fracture during cyclic loading when compared with modified anterior tension wiring and cannulated lag screws with anterior tension wiring.
