Open Surgical Hip Dislocation for an Acetabular Osteoid Osteoma - A Case Report

Osteoid osteoma is a benign tumor that accounts for roughly 10-12% of all benign bone forming tumors. This tumor generally occurs within the first three decades of life and occurs more commonly in males. This lesion is painful and is generally worse at night and has relief of symptoms with the use of NSAIDs. Osteoid osteoma is characterized by the production of osteoid surrounded by a rim of sclerotic bone. These lesions most commonly occur in long bones such as the proximal femur, however they can occur anywhere. Rarely, as with our patient, have these lesions been reported in the acetabulum.

Gibson approach and surgical hip dislocation according to Ganz in the treatment of femoral head fractures

Background The purpose of the study is to evaluate clinical and radiological outcomes in those patients with femoral head fracture, treated with open reduction and internal fixation through Gibson approach and Ganz flip trochanter osteotomy. The treatment of Pipkin fractures is very challenging, especially for small trauma centers, because of the unusual fracture patterns and high-level surgical skills required. Case presentation Between 2017 and 2020, nine cases of Pipkin fractures came to the Emergency Department at the Trauma Center of our Hospital in Rome. Inclusion criteria were the diagnosis of femoral head fracture, the open reduction and internal fixation as surgical choice and at least 24 months follow-up. Patients older than 65 years and those treated through total hip replacement or combined hip procedure (CHP) were excluded. Thus, five patients were included in our case series. The clinical outcome was evaluated according to Western Ontario and McMaster Universities Arthritis Index, Vail Hip score, modified Harris Hip score and Merle D’Aubignè Postel score. Radiographic assessment was scored according to Epstein-Thompson classification and heterotopic ossification was assessed through Brooker classification. The mean follow-up was 24 months (range 12-24). Average modified Harris Hip score was 92.1 points (range 75.9–100), and the average Vail score was 81.8 (range 55-95). WOMAC score was assessed in three different subscales, pain (A), stiffness (B) and physical condition (C), with the following results: 1.4 A (range 0-7), 1.2 B (range 0-6) and 6.4 C (range 0-22). Merle d’Aubignè Postel score resulted excellent for four patients and good for one patient. According to Epstein-Thompson score of the radiological outcome, four patients showed a good result and one a fair result. No mechanical or infective complications occurred in the five patients. Conclusions Gibson’s approach and surgical hip dislocation through Ganz trochanteric flip osteotomy allow a good exposure of the femoral head and acetabulum, giving us the possibility to perform an anatomical reduction of the fracture. In our case series, satisfactory clinical and radiological short-term results were obtained without significant complications.

Neglected Neck of Femur Fracture Managed by Surgical Hip Dislocation: A Case Report and Literature Review

Introduction: Femoral neck fractures (FNFs) in young adults are relatively uncommon emergency that requires early diagnosis and management possible to prevents joint complications. Case Report: A 24-year-old male presented with a right hip pain for 3 months after a heavy physical exercise during military training. The imaging exhibited a transcervical FNF with displacement and a potential of avascular necrosis (AVN). The patient was managed by Open reduction and internal fixation through surgical hip dislocation (SHD) and bone grafting from the right iliac bone. The patient returned to his full military services 14 weeks following the surgery and was followed for 3 years without any symptomatic or functional problems. Conclusion: SHD could be one of the surgical options hired in the management of late presentations of FNFs in young adults with high suspicion of AVN.
