Osteochondral autograft transplantation (mosaicplasty) for the osteochondral defects of the femoral head is generally performed with safe dislocation of the hip joint. Here, we present a 27-year-old male patient who had a symptomatic osteochondral defect of the femoral head and underwent mosaicplasty applied by hip arthroscopy without surgical hip dislocation. The preoperative radiological evaluation showed a focal osteochondral defect on the weight-bearing surface of the femoral head. With the assistance of hip arthroscopy, the defect area was reconstructed with osteochondral plug, which was taken from the ipsilateral knee, inserted in a retrograde fashion, and positioned with the spherical surface of the femoral head cartilage under fluoroscopic and arthroscopic control...

Femoro-acetabular impingement (FAI) is associated with significant acetabular cartilage damage and degenerative arthritis. To understand the contact stress and thus biomechanical mechanisms that may contribute to degeneration, the material behaviour of the cartilage layer is required. The objective of this study is to determine the fibril-reinforced poroelastic properties and composition of cartilage from cam deformities and to compare to those of normal cartilage. Patients undergoing surgical treatment of a symptomatic cam FAI deformity were recruited from the clinical practice of one of the authors...

INTRODUCTION: Surgical treatment of malignant bone tumors of the pelvis with periacetabular involvement is constantly evolving. Even though acetabular reconstructions improve quality of life without impairing cancer control, they are not complication free. Our purpose is to describe the functional outcomes and surgical complications of different reconstructive techniques for Enneking zone II tumors. MATERIAL AND METHODS: Fifteen patients underwent surgery for malignant pelvic bone tumors between 2002 and 2012...

As anatomical reduction of the articular surface of femoral head fractures and restoration of damaged cartilage are essential for good long-term results, many treatment options have been suggested, including fixation of the fracture using various surgical exposures and implants, as well as arthroscopic irrigation and debridement, bone marrow stimulating techniques, osteochondral allograft, autograft, and autogenous chondrocyte implantation. We report a case of osteochondral autograft harvested from its own femoral articular surface through surgical hip dislocation...

PURPOSE: The optimal treatment for osteochondral fracture of the femoral head associated with posterior dislocation remains unclear. A case can be made to treat small fragments and those that concentrically reduce nonoperatively. On the other end of the spectrum are those where significant size and residual displacement warrant consideration of operative fixation. This video demonstrates the treatment of a large complex multifragmentary osteochondral femoral head fracture with surgical dislocation...

PURPOSE: vascularized fibular grafting has been used to treat osteonecrosis of the femoral head in younger patients. Although the results described in the literature are promising, the failure rate is still significant, especially in steroid users. This study was undertaken to learn more, on a histopathological level, about the mechanism of vascularized fibular graft failure. METHODS: fifteen femoral heads removed at conversion to total hip arthroplasty were analyzed...

Management of a posterior shoulder dislocation with an associated reverse Hill-Sachs lesion is challenging, both diagnostically and therapeutically. Diagnosis is frequently delayed or missed, whereas the resulting humeral head defect is often larger and more difficult to salvage than in anterior shoulder dislocations. This report presents the case of a 29-year-old male with a recurrent posterior shoulder dislocation associated with a large reverse Hill-Sachs defect, treated with bone augmentation of the lesion with a combination of fresh femoral head allograft and a locally harvested humeral head autograft transfer, with a successful outcome...

INTRODUCTION: Obturator hip dislocations with an associated osteochondral fracture of the femoral head are uncommon. The treatment of these injuries is challenging and the functional outcomes are poor. Though the injury pattern has been described previously in literature, there are few published reports regarding treatment options. This case report illustrates a novel technique for fixation and stabilization for an unusual injury involving an obturator hip dislocation and an osteochondral impaction fracture of the femoral head...

BACKGROUND: Hip arthroscopy has allowed the diagnosis and treatment of chondral injuries. METHODS: We retrospectively analysed the intraoperative data of 359 patients treated with hip arthroscopy from January 2012 to December 2013. We estimated the frequency, location and extension of acetabular cartilage (AC) injuries and their correlation to femoroacetabular impingement (FAI). RESULTS: Grade 1 and 2 acetabular chondral lesions were not statistically significant in incidence, location and extension...

Pipkin fractures are relative rare high-energy lesions characterized by an intra-articular fracture of the femoral head after posterior hip dislocation. Early anatomic reduction and stable fixation are the main goals of treatment. This case evaluates the outcome of managing Pipkin type 2 fracture with acute osteochondral defect of the femoral head using "rotational osteoplasty" and bioabsorbable polylactate pin fixation. 24-year-old male patient was involved in a motorcycle accident, suffering from a left hip fracture-dislocation, and pelvic Computed Tomography revealed a Pipkin type 2 lesion...

This study evaluated complications associated with implant depth in headless compression screw treatment of an osteochondral fracture associated with a traumatic patellar dislocation in a 21-year-old woman. Computed tomography and X-rays showed one lateral fracture fragment measuring 25 × 16 mm. Osteosynthesis was performed with two headless compression screws. Five months later, the screws were removed because of patella-femoral implant friction. We recommend that the screw heads be embedded to a depth of at least 3 mm below the cartilage surface...

Osteochondritis dissecans (OCD) of the femoral head is not a common source of hip pain. Hip arthroscopy is becoming a more frequent indication for intra-articular pathologies of the hip. Osteochondral autologous transplantation is a promising technique that theoretically can reconstruct osteochondral lesions of the femoral head. We describe our technique for arthroscopic antegrade osteochondral autologous transplantation for the treatment of OCD of the femoral head. The advantages of this technique include that it is a less invasive method with the ability to assess and treat intra-articular pathologies associated with OCD of the femoral head at same time...

OBJECTIVE: In patients with osteoarthritis (OA), bone marrow lesions (BMLs) are intimately linked to disease progression. We hypothesized that aberrant multipotential stromal cell (also known as mesenchymal stem cell [MSC]) responses within bone tissue contributes to BML pathophysiology. The aim of this study was to investigate BML and non-BML native subchondral bone MSCs for numeric, topographic, in vitro functional, and gene expression differences. METHODS: Ex vivo 3T magnetic resonance imaging (MRI) of the femoral heads of 20 patients with hip OA was performed...

Although femoroacetabular impingement (FAI) syndrome is included in the etiology of lesions involving the acetabular labrum and acetabular cartilage, it is one of many possible reasons behind osteochondral lesions in the femoral head. Herein, we present clinical findings and outcomes of two cases with osteochondral defects and cam type impingement of femoral head. Both cases underwent autologous osteochondral mosaicplasty along with femoral osteochondroplasty following controlled hip dislocation. Harris hip scores improved significantly postoperatively and magnetic resonance imaging showed an adequate graft union and formation of a healthy chondral surface at the final assessment...

Simultaneous bilateral locked posterior dislocation of the shoulder is a rare injury. Herein, we present a 59-year-old male case with a three-month history of an irreducible locked bilateral posterior dislocation of the shoulders with an associated large impression fracture on the anteromedial aspect of both humeral heads after a grand mal type epileptic seizure. Plain X-ray and computed tomograph revealed a defect on the right side more than 40% of the articular surface, and on the left side, 30%. He was treated with a one-stage operation with a reconstruction of femoral head osteochondral allograft on the right side and transfer of the osteotomized tuberculum minus with its attached subscapularis tendon into the defect (modified McLaughlin technique) on the left side...

REVIEW
J Anthonissen, P M Rommens, A Hofmann
Different joint-preserving techniques have been described for the treatment of traumatic osteochondral lesions of the femoral head especially in young active patients. Mosaicplasty with autologous transplantation of osteochondral cylinders is an established surgical technique in the knee. Little evidence, however, exists for the treatment of osteochondral lesions in the hip using this technique. Here, we report on the result of treatment of a traumatic 5 cm(2) osteochondral lesion of the femoral head in a young patient treated with mosaicplasty...

This study aimed to determine the optimal starting material for the development of an acellular osteochondral graft. Osteochondral tissues from three different species were characterised; pig (6 months), cow (18 months) and two ages of sheep (8-12 months and >4 year old). Tissues from the acetabulum and femoral head of the hip, and the groove, medial and lateral condyles and tibial plateau of the knee were assessed. Histological analysis of each tissue allowed for qualification of cartilage histoarchitecture, glycosaminoglycan (GAG) distribution, assessment of cellularity and cartilage thickness...

Femoral head chondroblastoma is an infrequent tumor, accounting for approximately 1-2% of benign bone tumors. It occurs more frequently in young male patients. It's most frequent locations include the proximal humerus, proximal femur, distal femur and proximal tibia. The femoral head is the third most frequent site of this tumor. There is no specific treatment for this entity; reported treatments range from acetabular osteotomies and osteochondral grafts, to vascularized fibular grafts, all of them with good results...

BACKGROUND: Traumatic posterior hip dislocation in children is a rare injury that typically is treated with closed reduction. Surgical treatment is typically recommended for nonconcentric reduction with joint space asymmetry with entrapped labrum or an osteochondral fragment. The surgical hip dislocation (SHD) approach allows for full assessment of the acetabulum and femoral head and has been our preferred surgical strategy. The purpose of this study was to (1) describe the intra-articular pathologic findings seen at the time of SHD; and (2) to investigate hip pain, function, and activity level of a cohort of children and adolescents after open treatment of a posterior hip dislocation using the SHD approach...
