BACKGROUND: Arthroscopic labral base repair (LBR) in the hip is a previously described technique designed to restore the native functional anatomy of the labrum by reproducing its seal against the femoral head. LBR has been shown to have good short-term outcomes. Hypothesis/Purpose: The purpose was to evaluate clinical outcomes of an LBR cohort with a minimum 5-year follow-up. It was hypothesized that patients who underwent LBR would continue to have significant improvement from their preoperative scores and maintain scores similar to their 2-year outcomes...

INTRODUCTION: Posterior comminution of the femoral neck fracture is a major cause of delayed and non-union owing to the loss of the buttressing effect against the posterior rotation. When a femoral neck fracture with posterior comminution is anatomically reduced, only the anterior portions of the femoral neck fracture surfaces are brought into contact leaving a posterior defect. The purpose of this study was to evaluate the use of fibular strut grafting and dynamic hip screw (DHS) for fresh femoral neck fractures with posterior comminution in young patient less than 50 years...

Free vascularized fibular grafting after core decompression and debridement of necrotic lesions is an effective surgical treatment of avascular necrosis of the femoral head. A technical challenge encountered in performing this procedure is ensuring adequate debridement of necrotic parts while preserving healthy bone. A previously described method accomplishes this indirectly using radioactive contrast media and fluoroscopy, increasing the risk of radiation exposure. We propose a surgical technique using standard arthroscopic equipment to visualize inside the femoral head, facilitating precise and accurate debridement without additional radiation exposure...

Steroid-induced avascular necrosis of the femoral head (SANFH) is a mainly bilateral complication of steroid therapy that involves extensive necrosis, and frequently occurs in young and middle-aged individuals, with a high disability rate. Autophagy is an intracellular lysosomal degradation process occurring in numerous diseases. However, the effect of dexamethasone (DXM)-induced autophagy on osteoblasts is unclear. The aim of the present study was to investigate the effects of autophagy on SANFH. In the present study, femoral head of SANFH patients was collected, and the autophagy in the samples was evaluated...

A 32-year-old African-American woman with a history of sickle cell disease presented for surgical evaluation of left total hip arthroplasty due to avascular necrosis of the femoral head. In anticipation of a complex orthopedic procedure, pre-surgical blood work was ordered. The patient's Fenwal blood sample typed as group O, D+. Although the patient had a history of anti-Fya, the antibody identification was inconclusive, so the workup was sent to a reference laboratory. The patient was last transfused with red blood cells (RBCs) 2 years earlier, but had no history of transfusion reactions...

BACKGROUND: The anterolateral (AntLat) surgical approach may spare the blood supply to the femoral head and improve the accuracy of cup positioning in metal-on-metal hip resurfacing arthroplasty. Thereby, potentially lessen complications such as avascular head necrosis, femoral neck narrowing and fracture, improve implant fixation, and lessen periprosthetic bone mineral density (BMD) loss. METHODS: Between November 2008 and January 2012, a randomized clinical trial was performed at Aarhus University Hospital...

Steroid-induced avascular necrosis of the femoral head (SANFH) is a major limitation of long-term or excessive clinical administration of glucocorticoids. Fludarabine, which is a compound used to treat various hematological malignancies, such as chronic lymphocytic leukemia, acts by down-regulating signal transducer and activator of transcription 1 (STAT1) by inhibiting STAT1 phosphorylation in both normal and cancer cells. This study assessed the effects of fludarabine in vitro (primary murine osteoblasts) and in vivo (rat SANFH model)...

INTRODUCTION: Management of Pauwels type-3 vertical femoral neck fractures has been a challenging clinical problem as they experience high shear forces and thus a greater risk of treatment failure. There is no apparent consensus on the optimal implant type for these injuries. We developed a modified dynamic hip screw (DHS), which was designed to a cage in the lag screw, loaded with autologous bone graft for the treatment of Pauwels type-3 vertical femoral neck fractures. METHODS: Between February 2010 and January 2012, 17 consecutive patients with Pauwels type-3 vertical femoral neck fractures were treated with the modified DHS loaded with autologous bone graft...

PURPOSE: Based on previous investigations on the vascular blood supply to the femoral head, a technique for anatomical reduction after slipped capital femoral epiphysis was developed. This technique is a modification of the original technique by Dunn using a retinacular soft-tissue flap. This allows the visual control of the epiphyseal vascular blood supply. We report the experience at the inventor's institution with a critical discussion of the available literature. METHODS: Using a trochanteric osteotomy for surgical dislocation of the hip, a retinacular soft tissue flap is created containing the deep branch of the medial femoral circumflex artery, the external rotators and the capsule...

BACKGROUND: Slipped capital femoral epiphysis (SCFE) is a frequent disorder of the adolescent hip, which may lead to avascular necrosis (AVN) of the femoral head, chondrolysis and early osteoarthritis due to the post-slip deformity of the proximal femur. To warrant the best possible outcome for the affected (and contralateral) hip, early diagnosis and proper treatment are needed. METHODS: A review of the literature was undertaken to identify today's role of available imaging modalities in the management of SCFE...

PURPOSE: Complete visualization of certain acetabular fractures of posterior wall or column with cranial extension involving superior dome from standard surgical exposures is a challenge. Osteotomy of the greater trochanter has been used to enhance fracture visualization, especially the dome, in posterior and lateral exposures of the acetabulum. It also decreases the need for excessive muscle retraction. The purpose of the study was to investigate the outcome associated with trochanteric flip osteotomy in the management of certain acetabulum fractures...

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...

With disease progression, avascular necrosis (AVN) of the femoral head may lead to a collapse of the articular surface. The exact pathophysiology of AVN remains unclear, although several conditions are known that can result in spontaneous cell death, leading to a reduction of trabecular bone and the development of AVN. Hip AVN treatment is stage-dependent in which two main stages of the disease can be distinguished: pre-collapse (ARCO 0-II) and post-collapse stage (ARCO III-IV, crescent sign). In the pre-collapse phase, core decompression (CD), with or without the addition of bone marrow (e...
