Developmental dysplasia of the hip (DDH) causes anatomical changes that cause early coxarthrosis. Although risf factors have been determined, the aetiology and physiopathology remains exactly unknown. Neonatal screening with physical examination and ultrasound have been stablished in order to diagnose this disease early in life. A diagnosis in the first months of life is essential as it enables...

Transient osteoporosis of the hip (TOH) is a rare disorder characterized by acute severe coxalgia and temporary osteopenia in the proximal femur. Although most cases were unilateral or staged bilateral TOH, some authors reported that the pregnant patients simultaneously had TOH in their bilateral hips. However, there has been no report of simultaneous bilateral TOH in the patient without pregna...

  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...

This work is based on a study of necrosis in 150 femoral heads in adults who had no evidence of such causal factors as a fracture, dislocation, caisson disease, sickle-cell anaemia or Gaucher’s disease (Fig. 1). This condition has been recognised during the last ten years: but only eleven cases were seen before 1958, and no less than 139 during the next five years. Idiopathic necrosis was descr...

Ultrasound (US) imaging is the modality of choice in many clinical applications compared to other imaging modalities, such as computed tomography (CT). US images are patient-specific, operator-dependent, and machine specific. However these US images are affected by signal dropouts, artefacts, missing boundaries, attenuation, shadows, and speckle, making US one of the most challenging modalities...

The aspherical coxa magna femoral head can be made more spherical by intra-articular osteotomy. The Ganz technique of femoral head reduction osteotomy to reduce the size and restore the spherical shape of the femoral head has been performed in 20 patients over the past 5 years. A good or excellent functional and radiographic result was obtained in 14 of the 20. A fair result (decreased pain but...

Objective To analyze the effects of the acetabular fracture index (AFI) and other factors on the functional outcome of patients with acetabular fractures involving the posterior wall. Methods Forty-eight patients who underwent surgery in our department were reviewed. According to the AFI, which indicates the percentage of remaining intact posterior acetabular arc, the patients were divided into...

Due to the pattern of its blood supply, the femoral head is particularly vulnerable to avascular necrosis (AVN). Nontraumatic AVN is a devastating disorder affecting young patients, and despite treatment it normally follows a progressive course toward a destructive osteoarthropathy. Magnetic resonance (MR) imaging is currently used in major classification systems solely for early detection of f...

A broken guide wire while operating on hip is one of every surgeon's most dreaded nightmares. We report here a method which was used successfully to retrieve a broken guide wire from a patient who was being operated for core decompression and fibular grafting for avascular necrosis of the femoral head.

Since the recent publication of studies of the vascular pattern of the proximal femoral epiphysis in man by Tucker (1949), Trueta and Harrison (1953), Judet, Judet, Lagrange and Dunoyer (1955), and Trueta (1957) there has been a renewed interest in the mechanism of capital necrosis after fractures of the femoral neck. The literature on the subject is so extensive that no effort will be made her...
