Comparative StudyChronic rupture of the long head of the biceps tendon: comparison of 2-year results following primary versus revision open subpectoral biceps tenodesis.
The purpose of this study was to evaluate the clinical results of surgical repair for proximal long head of the biceps (LHB) tendon ruptures comparing chronic primary and postsurgical revision LHB tendon ruptures. ⋯ Level III; Retrospective comparative study.

Which factor is most important for occurrence of cutout complications in patients treated with proximal femoral nail antirotation? Retrospective analysis of 298 patients.
Mechanical complications, such as cut-out of the head-neck fixation device, are the most common causes of morbidity after trochanteric femur fracture treatment. The causes of cut-out complications are well defined in patients who are treated with sliding hip screws and biaxial cephalomedullary nails but there are few reports about the patients who are treated with proximal femoral nail antirotation. ⋯ Althought obtaining proper tip-apex distance is important to prevent cutout complication in these fractures, if the fracture is not reduced in varus position and helical blade is inserted in the proper quadrant, possibility of cut-out complication is very low even in the patients with high tip-apex distance.

Cobalt serum levels differ in well functioning Birmingham resurfacing and Birmingham modular THA.
Metal-on-metal (MoM) bearings are known to release metal ions secondary to wear and corrosion. This may cause local reactions (adverse soft tissue reactions and osteolysis) and systemic effects. Little is known about the exact pattern and the differences between large head MoM total hip replacements (THA) and resurfacings (HR). ⋯ Considering that HR and MoM-THA used the same MoM bearing design, increased cobalt levels may be related to trunnion wear or corrosion. Elevated cobalt levels should raise concern for corrosion related failure in MoM-THA.

Serial MRI evaluation following arthroscopic rotator cuff repair in double-row technique.
So far, recurrent rotator cuff defects are described to occur in the early postoperative period after arthroscopic repair. The aim of this study was to evaluate the musculotendinous structure of the supraspinatus, as well as bone marrow edema or osteolysis after arthroscopic double-row repair. Therefore, magnetic resonance (MR) images were performed at defined intervals up to 2 years postoperatively. ⋯ Recurrent defects after arthroscopic reconstruction of supraspinatus tears in modified suture bridge technique seem to occur between 12 and 24 months after surgery. Serial MRI evaluation shows good muscle structure at all time points. Postoperative bone marrow edema disappears completely several months after surgery. Signs of osteolysis seem to appear caused by bio-absorbable anchor implantations.

Incidence, location and classification of glenoid labrum meniscoid folds.
The purpose of the present study was to arthroscopically investigate the incidence and location of labral meniscoid folds of the shoulder joint, as well as to classify them into types and detect any possible correlation with gender, side and age of patients. ⋯ Meniscoid folds are quite common in shoulder joint. Labral meniscoid folds are located more often at an anterosuperior position of shoulder joints and their incidence tends to be higher in older patients, while in male ones they are located in a more anterior position in comparison to female patients where they are located more superiorly.
