Component placement accuracy of two digital intraoperative fluoroscopy supplementation systems in direct anterior total hip arthroplasty.
Intraoperative fluoroscopy (IF) may increase accuracy of component placement when performing direct anterior approach total hip arthroplasty (THA), however, unguided IF continues to produce inconsistent results. Supplementation of IF, with a digital grid (Grid) system or digital overlay (Overlay), may increase component placement accuracy. The purpose of this study was to compare component placement accuracy following THA when IF was supplemented with the Grid or Overlay technique. ⋯ Although no difference was found between the Grid and the Overlay cohorts for LLD, GHO or abduction angle, the Overlay resulted in greater accuracy for acetabular component anteversion angle, with only a slight decrease in surgical efficiency.

Does a skin incision along Langer's lines reduce complications following fixation of displaced middle-third clavicle fractures?
Internal fixation of displaced middle-third clavicle fractures is a widely used treatment but is frequently associated with post-operative complications. The aim of this study is to investigate whether or not using a skin incision along Langer's lines, as opposed to a traditional transverse incision, reduces complications. ⋯ Based on our data, an incision following Langer's lines does not reduce the rate of complications following fixation of displaced middle-third clavicle fractures.

Implant-free iliac crest bone graft procedure shows anatomic remodelling without redislocation in recurrent anterior shoulder instability after short-term follow-up.
With the help of a J-shaped bicortical iliac crest bone graft, the morphology of the glenoid can be augmented without having to use screws to achieve glenohumeral stability. The aim of this retrospective clinical study was to evaluate the clinical stability and function of the shoulder joint as well as the radiological remodelling process and arthropathic outcomes following the J-bone graft technique. ⋯ The results of this study show a successful stabilisation of the shoulder joint and a low complication rate following the J-bone graft technique. Remodelling of the bone graft could be demonstrated, which in turn led to an almost perfect glenoid surface area of 100%.

Functional stability: an experimental knee joint cadaveric study on collateral ligaments tension.
Applying proper tension to collateral ligaments during total knee arthroplasty surgery is fundamental to achieve optimal implant performance: low tension could lead to joint instability, over-tensioning leads to pain and stiffness. A "functional stability" must be defined and achieved during surgery to guarantee optimal results. In this study, an experimental cadaveric activity was performed to measure the minimum tension required to achieve knee functional stability. ⋯ Results agree with other experimental studies, showing that the tensions required to stabilize a knee joint are lower than the ones applied nowadays via surgical tensioners. To reach functional stability, surgeons should consider such results intraoperatively and avoid ligament laxity or over-tension.

Soaking ACL grafts in vancomycin solution (1 mg/ml) reduces the infection rate without increasing the risk for re-rupture and arthrofibrosis.
The aim of the present study was to evaluate if the vancomycin (1 mg/ml) is effective for the prevention of septic arthritis after ACL reconstruction. The hypothesis was that local antibiotic prophylaxis by soaking ACL grafts in vancomycin results in significantly less infections than ACL reconstruction without local antibiosis. ⋯ III.
