Clinical Trial
Bone remodelling around the Metha short stem in total hip arthroplasty: a prospective dual-energy X-ray absorptiometry study.
On the basis of positive clinical results with mid- and long-term follow-up using the Mayo short stem, the Metha neck-preserving stem (BBraun, Aesculap, Tuttlingen, Germany) was introduced. The purpose of this study was to validate the implant design by direct acquisition of bone remodelling data from total hip arthroplasty (THA) recipients using dual-energy X-ray absorptiometry (DEXA). ⋯ Stress shielding seems to occur at the greater trochanter due to the vast cross-section of the implant. However, the aim of proximal load transfer of the Metha stem seems to be partially achieved. DEXA analysis revealed a concentrated load distribution on the medial portion of the femur, which is an important region to guarantee long-term implant survival.

Review Comparative Study
Plate fixation versus intramedullary fixation for displaced mid-shaft clavicle fractures: a systematic review.
The optimal surgical approach for displaced midshaft clavicle fracture remains controversial. The objective of this systematic review is to compare functional outcome and complications after plate fixation and intramedullary fixation for displaced midshaft clavicle fractures. ⋯ High quality evidence from one study and low quality evidence from three studies showed no difference in functional outcome or complications after plate fixation or intramedullary fixation for displaced midshaft clavicle fractures.

Comparative Study
Glenoid axis is not related with rotator cuff tears--a magnetic resonance imaging comparative study.
The relationship between glenoid version angle and rotator cuff pathology has been described. However, the effect of glenoid version angle on rotator cuff pathology is still unknown. The aim of this study was to investigate whether there is an impact of glenoid version angle on rotator cuff pathology. ⋯ This study demonstrated no significant relationship between glenoid version angle and rotator cuff pathology. Therefore, the pathologies that can be related to the cuff itself should be investigated if the pathology cannot be explained by an extrinsic cause in subjects with rotator cuff pathology.

The development of minimal-incision techniques for total hip replacement with preservation of soft tissue is generally associated with faster rehabilitation, reduction of postoperative pain and increased patient comfort. The aim of this study was to compare a minimal-incision anterior approach with a transgluteal lateral technique for hip replacement surgery with respect to postoperative pain, consumption of rescue medication, length of hospital stay and time to reach a defined range of motion. ⋯ The implantation of a hip prosthesis through a minimal-incision anterior approach is successful in reducing postoperative pain and consumption of pain medication. Time to recovery and length of hospital stay are also influenced positively. Pain increases during physiotherapy, and may be mitigated by adopting limited weight bearing during the early postoperative period.

The study was carried out to report the results of wide resection in sacral chordoma using a posterior approach and gauze packing technique. ⋯ Wide resection via the posterior approach and gauze packing technique could be used for management of sacral chordoma with acceptable results.
