Osteonecrosis of femoral head (ONFH) is a disabling condition of young individuals with ill-defined etiology and pathogenesis. Remains untreated, about 70-80% of the patients progress to secondary hip arthritis. Both operative and nonoperative treatments have been described with variable success rate. Early diagnosis and treatment is the key for success in preserving the hip joint. Once femoral head collapses (>2 mm) or if there is secondary degeneration, hip conservation procedures become ineffective and arthroplasty remains the only better option. We reviewed 157 studies that evaluate different treatment modalities of ONFH and then a final consensus on treatment was made.
In osteonecrosis the success of interventions that forestall or prevent femoral head collapse and maintain hip function would represent a substantial achievement in the treatment of this disease. A review of recent literature regarding bisphosphonate, anticoagulant, and vasodilators and biophysical modalities have demonstrated efficacy in reducing pain and delaying disease progression in early stage osteonecrosis. Though it has been considered still insufficient, to support their routine use in the treatment or prevention of osteonecrosis of the hip. Core decompression with modification of technique is still one of the safest and most commonly employed procedures with evidence based success in the pre-collapse stage of AVN of femoral head. The additional use of bone morphogenic protein, and bone marrow stem cells may provide the opportunity to enhance the results of core decompression. At present, the use of large vascularised cortical grafts, the other surgical procedure with high success rate is still not common due to technical difficulty in surgery. Likewise osteotomies are also not getting common as arthroplasty is getting more acceptable, so is awaited without any intermediate big surgical interventions.
Poor reduction, associated injuries, fracture displacement of >20mm, joint dislocation and late surgery definitely carry poor prognosis in predicting the outcome of surgically treated acetabular fractures.
purpose. To review records of 5 patients with anterior coronal trochlear fractures. Methods. Four men and one woman aged 25 to 46 (mean, 34) years underwent cancellous screw (n=3) or Kirschner wire (n=2) fixation for anterior coronal fractures of the humeral trochlea after falling on a flexed elbow. Patients were operated on through a medial approach. Three patients who had a large osteochondral fragment underwent fixation using 4-mm AO partially threaded cancellous screws. Two patients who had a small un-amenable osteochondral fragment (with articular cartilage damage) underwent fixation using Kirschner wires. Patients were evaluated using the Mayo Elbow Performance Index (MEPI) based on pain, arc of motion, stability, and functional disability. results. The mean time from injury to surgery was 7 (range, 5-10) days. The mean follow-up period was 2.7 years. No patient had any wound-related problems, postoperative neurovascular compromise, or avascular necrosis. Radiographic union was noted after a mean of 14 weeks. Outcome was excellent in 4 patients and good in one. The mean arc of flexionextension was 101º and the mean arc of supinationpronation was 130º. The mean MEPI was 92. The MEPI was relatively low in the 2 patients with a small osteochondral fragment who underwent Kirschner wire fixation. One patient with articular cartilage damage developed mild degenerative changes and had to change his occupation. The remaining 4 patients were pain-free and had returned to their occupations within 4 months. conclusion. Open reduction and screw fixation restores articular congruency and enables early mobilisation. Small coronal shear fractures of the trochlea not amenable to screw fixation should be fixed with Kirschner wires.
Acetabular fractures involving the weight-bearing dome if reduced by closed means can be maintained by heavy lateral and longitudinal traction resulting in good clinicoradiologic outcome comparable with operative management.
Angle blade plate provides rigid stability and offloads any shearing force over the fibular graft when used for revision internal fixation in aseptic femoral-neck nonunion. Thus, the fibular graft only serves the purpose of osteogenesis and stimulates the surrounding host cells to promote healing at the nonunion site. We recommend the angle blade plate and autogenous fibular graft as a viable option for hip-joint salvage in revision internal fixation of aseptic femoral-neck nonunion.
Background: Standard Harris Hip Score (HHS) is a validated tool, to measure the functional status of an individual and has been traditionally used to assess the condition of a patient with hip pathologies. Harris hip score in its standard form includes a physician's physical examination component which has a high inter-observer variability. A modified version of HHS (MHHS) was devised and brought into use, but has not been validated as an outcome measure, post total hip replacement (THR) in Indian population. Methods: 101 patients with 122 hips for whom THR was done, were followed up, and HHS and MHHS were recorded at a minimum followup of 6 months. Results: The mean MHHS was 78.97 with a standard deviation of 15.017. There was positive correlation between the two functional outcome scores with a p value of 0.001. MHHS was found to be reliable with a significant intraclass correlation coefficient (p = 0.001). Conclusion: MHHS is a reliable and valid tool to measure functional outcome in patients undergoing Total Hip Replacements.
