Clinical Trial
Evaluation of bipolar hemiarthroplasty for the treatment of steroid-induced osteonecrosis of the femoral head.
Bipolar hemiarthroplasty (BHA) for idiopathic osteonecrosis of the femoral head (ONFH) is performed at our institution. The purpose of this study was to evaluate the clinical and radiographic findings after BHA for the treatment of steroid -induced ONFH. ⋯ BHA, with strict surgical indications, may be a good option for treating ONFH. Based on these results, total hip arthroplasty is recommended for patients with ARCO stage IV ONFH or for patients under 40 years of age.

A rupture of the Achilles tendon may heal in continuity, resulting in a lengthened Achilles tendon. The elongated structure must be shortened to restore effective push off. We report the results of a longitudinal study using Z-shortening of ruptured Achilles tendons that healed in continuity but were elongated. ⋯ Managing a healed Achilles tendon rupture using Z-shortening is safe and effective, providing good recovery and early weight bearing and active ankle mobilisation. Such patients should be warned that they are at risk for postoperative complications and that their ankle-plantar flexion strength is likely to be permanently reduced.

Circulating TGF-β1 levels were found to be a predictor of delayed bone healing and non-union. We therefore aimed to investigate some factors that can influence the expression of TGF-β1. The correlation between the expression of TGF-β1 and the different socio-demographic parameters was analysed. ⋯ TGF-β1 serum concentrations vary depending upon smoking status, age, gender, diabetes mellitus and chronic alcohol abuse at different times and therefore do not seem to be a reliable predictive marker as a single-point-in-time measurement for fracture healing.

Comparative Study
Variations in bifid superior transverse scapular ligament as a possible factor of suprascapular entrapment: an anatomical study.
The suprascapular region is the most common place for suprascapular nerve entrapment. The purpose of this research was to investigate the influence of the superior transverse scapular ligament (STSL) on the reduced space for suprascapular nerve passage at the suprascapular notch. Additionally, we precisely described other structures that seem important during arthroscopic and open procedures in this region. ⋯ Knowledge of the variations of the superior transverse scapular ligament is important for better understanding of the possible anatomical conditions that can promote suprascapular nerve entrapment. Its morphology should also be taken into particular consideration during surgical and arthroscopic procedures.

Osteonecrosis of femoral head remains a major complication of femoral neck fractures. It has been postulated that early internal fixation drastically reduces the incidence of osteonecrosis of the femoral head. However, there is a paucity of literature looking at the effect of time delay to internal fixation on the development of this late complication. In this study, we aim to assess the effect of time delay and method of internal fixation on the development of osteonecrosis in those less than 60 years of age. ⋯ Our study demonstrated that the method of internal fixation rather than delay in internal fixation was more predictive of osteonecrosis of the femoral head. We did not find support to the current belief that early surgical fixation of neck of femur fractures reduces the risk of osteonecrosis in patients less than 60 years.
