INTRODUCTION: Subtalar dislocation is an uncommon lesion in traumatology chiefly when it concerns the lateral form. Surgical treatment is required when a fracture is related or the dislocation is irreducible. Even well treated, these dislocations progress unavoidably to subtalar arthrosis, which stays well tolerated. CASE REPORT: A 46-year-old male with irreducible lateral subtalar dislocation caused sustentaculum tali incarceration confirmed on computed tomography (CT)...

Kienbock's disease, or avascular necrosis of the lunate, is a progressive disease ultimately resulting in end-stage arthrosis of the wrist. Various surgical treatments are available for different Lichtman stages of disease. We review the surgical options and indications, expected radiologic post-operative appearance, as well as detail potential surgical complications, as they relate to Kienbock's disease.

INTRODUCTION: Both the overall shape of the calcaneus and anatomical reduction of joint congruity are important prognostic factors. However, there is a significant lack of biomechanical data supporting the clinical importance of calcaneus height, length and heel width. The objective of this study was to determine the effects of abnormal calcaneus morphology on ankle-hindfoot biomechanics. HYPOTHESIS: The normal biomechanics of the ankle-hindfoot would be severely disrupted by the abnormal calcaneus morphology...

Deficiency of PRG4 (lubricin), the boundary lubricant in mammalian joints, contributes to increased joint friction accompanied by superficial and upper intermediate zone chondrocyte caspase-3 activation, as shown in lubricin-null (Prg4(-/-)) mice. Caspase-3 activity appears to be reversible upon the restitution of Prg4 either endogenously in vivo, in a gene trap mouse, or as an applied lubricant in vitro. In this study we show that intra-articular injection of human PRG4 in vivo in Prg4(-/-) mice prevented caspase-3 activation in superficial zone chondrocytes and was associated with a modest decrease in whole joint friction measured ex vivo using a joint pendulum method...

OBJECTIVE: Osteoblastoma (OB) is a painful, rare, benign bone tumour usually observed in young populations, and this condition involves the spine in up to one-third of cases. We sought to focus on the minimally invasive treatment of spinal OB with radiofrequency ablation (RFA) under computed tomography (CT) guidance. When performed near the spinal cord, surgery can lead to instability of the spine, sometimes requiring additional interventions to stabilise the segments involved, and can cause the precocious onset of arthrosis or other degenerative diseases...

BACKGROUND: Pigmented villonodular synovitis (PVNS) is a rare, benign proliferation of the synovium, commonly affecting the knee. Arthroplasty can successfully manage arthrosis in this population; however, outcome data is limited. The purpose of this study was to investigate the oncologic and functional outcome of patients undergoing total knee arthroplasty (TKA) in the setting of PVNS. METHODS: 48 patients were identified at our institution with histologically confirmed PVNS that subsequently received TKA...

Background Arthrosis of the knee is a common problem in Germany that is often treated with arthroplasty. To support the orthopaedic surgeon, person-matched instruments (PMI) are available from several providers. In this study we investigated the clinical and radiological outcome of the use of the PMI Visionaire(™) (Smith&Nephew). Furthermore, we investigated the influence of operative experience of the orthopaedic surgeon on the clinical and radiological results. Time in the operating room (OR) was identified as a parameter for cost effectiveness even during training to become an orthopaedic surgeon...

INTRODUCTION: Avascular necrosis (AVN) of the femoral or humeral heads in patients with sickle cell anemia is a common and painful condition. There is currently no gold standard treatment protocol for this condition. Typically, the pain is managed with narcotics and activity restriction until there has been collapse of the subchondral bone with a degree of arthrosis sufficient to warrant total joint arthroplasty. This method entails prolonged pain for the patient and decreases the ability to function occupationally and recreationally...

BACKGROUND: Lisfranc injuries are often missed initially or not anatomically reduced, leading to midfoot collapse, arthrosis, and pain. Operative management of these injuries is also fraught with complications, particularly with respect to the soft tissues. Wound dehiscence and infection are not uncommon. The goal of this study was to analyze the outcomes of a minimally invasive technique in reduction and percutaneous fixation of low-energy minimally displaced Lisfranc injuries and determine if it is a safe alternative to more traditional, open approaches...

BACKGROUND: The pathophysiology of microscopic colitis (MC) is not fully understood. A dysregulation of the adaptive immune response has been hypothesized, of which the maturation and function is imprinted in early life. Various other factors (e.g., hormonal factors) have also been found to be associated, sometimes, with minimal or conflicting evidence. The aims of this study were to evaluate whether an exposure to (microbial) agents in early life might be protective for MC development and to assess the role of several less well-established risk factors in one study...

BACKGROUND: Constrained condylar knee (CCK) prosthesis are common used for revision surgery but can also help surgeons to improve implant stability in primary knee arthroplasty, in fact in severe knee arthrosis with serious deformity associated with a significant instability a more constrained articulation is required. With introduction of second generation of semi-constrained prosthesis, rate of complication is real decreased and a good survival rate and functional score results is showed...

BACKGROUND: Subtalar joint arthrodesis is a common operative treatment for symptomatic subtalar arthrosis. Because excessive relative motion between the talus and calcaneus can delay or prohibit fusion, fixation should be optimized, particularly in patients at risk for subtalar arthrodesis nonunion. Tapered, fully-threaded, variable pitch screws are gaining popularity for this application, but the mechanical properties of joints fixed with these screws have not been characterized completely...

Background Subacromial impingement is a common reason for pain in the shoulder. Treatment is difficult and patients are not able to work for a long time. An increasing number of operative treatments can be observed although conservative treatment is effective, too. There is no study that observed how operative and conservative treatment influence ability to work. Methods 86 persons were included in this prospective study. Surgery was performed with an arthroscopy of the shoulder. Conservative treatment was carried out by a physiotherapist under control of the physician...
