Sciatic nerve injuries cause debilitating functional impairment, particularly when the injury mechanism and level preclude reconstruction with primary grafting. The purpose of this study was to demonstrate the anatomical feasibility of nerve transfers from the distal femoral nerve terminal branches to the tibial nerve and to detail the successful restoration of tibial function using the described nerve transfers. Six cadaveric legs were dissected for anatomical analysis and the development of tension-free nerve transfers from femoral nerve branches to the tibial nerve...

INTRODUCTION: Sciatic nerve injury (SNI) is a potentially devastating complication after total hip arthroplasty (THA). Intraoperative neural monitoring has been found in several studies to be useful in preventing SNI, but can be difficult to implement. In this study, we examine the results of using a handheld nerve stimulator for intraoperative sciatic nerve (SN) monitoring during complex THA requiring limb lengthening and/or significant manipulation of the SN. METHODS: A consecutive series of 11 cases (9 patients, 11 hips) with either severe developmental dysplasia of the hip (Crowe 3-4) or other underlying conditions requiring complex hip reconstruction involving significant leg lengthening and/or nerve manipulation...

BACKGROUND: Multiple surgical techniques exist to restore limb alignment and to balance soft tissues in valgus knees during total knee arthroplasty (TKA). One technique is to perform a lateral femoral epicondylar osteotomy. METHODS: A retrospective analysis was performed on all patients with a fixed valgus deformity that was corrected with a lateral femoral epicondylar osteotomy during TKA. Preoperative and postoperative Knee Society Knee Scores, knee stability, range of motion, and radiographic alignment were recorded...

Stabilization after a pelvic fracture can be accomplished using multiple techniques. The anterior external fixator has been traditionally used in variety of unstable pelvis either singly or in combination of posterior screws. These devices are cumbersome and restrict side turning and sitting particularly in obese patients. An alternative, anterior subcutaneous pelvic internal fixation technique (ASPIF) was developed which is well tolerated by patients for mobility and comfort and biomechanically more stable construct Complications of this construct included irritation of the lateral femoral cutaneous nerve, femoral nerve palsy &heterotypic ossification with reduced rates of infections and aseptic loosening as compared to external fixator...

Mucormycosis has emerged as a major threat to transplant recipients with high morbidity and mortality. This infection most commonly presents with rhino-sino-orbital localization. Gastrointestinal mucormycosis is uncommon, with presenting symptoms usually abdominal in nature. Here, we describe the case of a liver transplant recipient who developed gastrointestinal mucormycosis with an initial manifestation of femoral nerve palsy, ultimately resulting in fungal dissemination and patient demise. This case highlights the challenges in making a timely diagnosis of mucormycosis, particularly in immunocompromised patients...

BACKGROUND: Total hip arthroplasty (THA) in patients with sequelae of Legg-Calvé-Perthes disease (LCP) is technically demanding because of the disease related deformities occuring in the proximal femur and/or the multiplanar deformities secondary to corrective osteotomies in childhood. Little is known about the long-term outcome of the procedure in this challenging group of patients. METHODS: We carried out a systematic review of the literature to determine the functional outcome, complications and revision rate of THA in patients with sequelae of LCP disease...

Bilateral traumatic hip dislocations are extremely rare. Most of these are related to acetabular or proximal femoral fractures, consisting of complex lesions, and are rarely pure ligamentous injuries. Posterior dislocation is the most frequent. Some dislocations are accompanied by sciatic nerve palsy. The present case is a posterior bilateral hip dislocation with no other associated lesions, there are very few reports published with this clinical setting. The patient had good functional outcome.

The usage of stance- and swing-phase control orthoses (SSCOs) is a good option in patients with neuromuscular insufficiency of the quadriceps muscle in a broad range of musculo-skeletal disorders. The subjective sensation of improved mobility in daily life and walking comfort could be objectively confirmed by the ability to walk without crutches and by harmonization of the gait patterns in hip and knee. They could also be a considered mobility device after limb salvage surgery, which may even have an impact on preoperative decision making...
