Multicenter Study Comparative StudyA multicenter study to evaluate subscapularis muscle function using 5:30 o'clock portal for antero-inferior shoulder stabilization.
The purpose of this study was to compare the outcome after arthroscopic antero-inferior shoulder stabilization with and without using a 5:30 o'clock portal. ⋯ III.

Characteristics of secondary arthrofibrosis after intra-articular distal radius fracture.
The purpose of this study was to assess characteristics of radiocarpal arthrofibrosis after intra-articular distal radius fractures (DRF). ⋯ Fracture severity correlates with the development of rigid intra-articular FTF. In case of rigid FTF with restricted wrist motion arthroscopic debridement may be considered at the time of hardware removal.

A treatment strategy to avoid iatrogenic Pipkin type III femoral head fracture-dislocations.
Reduction is urgently required in cases of traumatic hip dislocation to decrease the risk of avascular necrosis of the femoral head. However, successful reduction may not always be feasible for hip dislocations associated with femoral head fractures. This irreducibility may provoke further incidental fractures of the femoral neck with resultant Pipkin type III injuries. The purpose of this study was to describe an appropriate treatment strategy for irreducible femoral head fracture-dislocations. ⋯ Repeated or forceful closed reduction of irreducible femoral head fracture-dislocation injuries may result in iatrogenic femoral neck fractures with Pipkin type III injuries. Before attempting reduction, careful examination of plain radiographs and CT images may be helpful for determining the safest treatment strategy.

Pull-out stability of anchors for rotator cuff repair is also increased by bio-absorbable augmentation: a cadaver study.
Osteoporosis is a highly focused issue in current scientific research and clinical treatment. Especially in rotator cuff repair, the low bone quality of patients suffering from osteoporosis is an important issue. In this context, non-biological solutions using PMMA for anchor augmentation have been developed in the recent past. The aim of this study was to evaluate whether augmentation of suture anchors using bio-absorbable osteoconductive fiber-reinforced calcium phosphate results in improved failure load of suture anchors as well. ⋯ The bio-absorbable cement in this study could be a promising augmentation material for RC reconstructions, but further research is necessary-the material has to be evaluated in vivo.

Arthroscopic knotless suprapectoral tenodesis of the long head of biceps: clinical and structural results.
Different techniques for tenodesis of the long head of biceps (LHB) have been described. Previous studies focused on intraosseously performed techniques while only little clinical data exists for epiosseously performed knotless LHB tenodesis. The hypothesis is that arthroscopic suprapectoral knotless epiosseous tenodesis of the LHB would have good clinical, cosmetic and structural results. ⋯ The arthroscopic suprapectoral epiosseous knotless tenodesis of the LHB provides good functional results. The high rate of examiner-dependent upper arm deformities can be explained by a non-physiological situation of the primary length-tension relationship or an elongation of the tendon after fixation.
