Insufficient blood flow to the proximal femur causes osteonecrosis of femoral head, which is known as head avascular necrosis (AVN). The underlying pathogenesis unclear, risk factors are likely influence microcirculation somewhat, but this has not been confirmed by research. In more than 75% cases, affects head. Methods: From August 2019 March 2022, 4 patients with FBAN were analyzed retrospect...

The authors have used bone endoscopy (medulloscopy) to improve the accuracy of the conventional technique for core decompression and grafting in 36 hips with avascular necrosis of the femoral head. Endocopy was found to facilitate debridement of the necrotic bone and to decrease the risk of perforation of the cartilage during debridement. The endoscopy-assisted technique failed, however, to imp...

Five hundred subcapital fractures of the femur have been subjected to close analysis, and follow-up has been continued for as long as possible during the past fifteen years (Table I). In the course of this review, the quality of reduction has clearly emerged as the factor most commonly affecting both the early and late results of treatment. Accurate apposition of the fragments is already known ...

  Background: Diagnosis of osteonecrosis of the femoral head (ONFH) is complicated due to the lack of reliable serum biomarkers. Up-regulation of alpha-2-macroglobulin (A2M) gene has been reported in glucocorticoid-induced ANFH rat model. This study aimed to investigate whether the serum level of alpha-2-macroglobulin (A2M) can be used for ONFH diagnosis. Methods: Serum protein capillary elect...

OBJECTIVE To evaluate the biomechanical changes of balloon inflating and cement filling in avascular necrosis of the femoral head using finite-element analysis. METHODS The procedure of percutaneous balloon inflating and cement filling was simulated in fresh specimen of human femoral head. CT scan and three-dimensional reconstruction were used to establish the three-dimensional model of the f...

Hip spica cast is a useful modality for the lower limb immobilization in children with hip and femur pathologies. Single, one half, double may be applied depending on indication. The position of also dependent underlying pathology which being applied. inguinal region knee are potential weak spots these should reinforce during application. Potential complications include plaster sores, breakage,...

Thinking about the future of the RBO automatically leads to reflection on the future of our specialty, since it is certain that the RBO will be responsible for publicizing this future. Taking a light but critical tone, I reflected on the progress of orthopedics over the last few years, by asking: In what way have we evolved? Is there much to be done? Recently, we commemorated the hundredth anni...

Introduction Traumatic dislocation of the hip with ipsilateral fracture neck femur is a rare injury because of the different mechanism of both these injuries. The management of such injuries is a challenge as the chances of nonunion and avascular necrosis of femoral head are very high with fixation methods. We report a case of obturator dislocation of the hip with ipsilateral fracture neck of t...

We followed, prospectively, 77 patients (90 hips) with early-stage, non-traumatic osteonecrosis of the femoral head for a mean period of nine years. At the time of final review, 56 (62%) were symptomatic. Using the Cox model, the initial radiological stage, the progression of staging, the reduction in size of the lesions and the percentage of necrotic volume on MRI were identified as risk facto...
