Pre-operative templating in total elbow arthroplasty: not useful.
Total elbow arthroplasty (TEA) is a definitive surgical procedure for treating rheumatoid arthritis and (posttraumatic) osteoarthritis of the elbow and is also useful in comminuted elbow fractures. Pre-operative digital templating may theoretically improve the surgical implantation of TEA, but reliability and predictive values of templating are unknown. The aim of this study was to determine the intra- and inter-observer reliability and the validity of pre-operative digital templating for TEA. ⋯ Pre-operative digital templating for TEA is a reliable method to plan implant sizes. However, the predictive value is low.

Comparative StudyDecreased femoral periprosthetic bone mineral density: a comparative study using DXA in patients after cementless total hip arthroplasty with osteonecrosis of the femoral head versus primary osteoarthritis.
Trabecular properties in osteonecrosis of the femoral head (ONFH) are altered for bone volume and structure in the femoral head and proximal femoral canal. We analysed the periprosthetic bone mineral density (BMD) as a correlate to bony ingrowth in patients with ONFH who received a cementless THA. ⋯ An altered periprosthetic bone stock in the proximal femur in patients with prior ONFH might be a possible risk factor for premature loosening of the femoral stem in THA. Surgeons need to consider coating and fixation philosophy of cementless implants when choosing the right stem for patients with ONFH.

Randomized Controlled Trial Comparative StudyComparison of three different incision techniques in A1 pulley release on scar tissue formation and postoperative rehabilitation.
The optimal surgical approach for trigger finger release remains controversial in hindsight of postoperative rehabilitation as well as scar tissue formation. In this study, we comparatively evaluated the outcome of three different types of skin incision by employing the "Disability of the Arm Shoulder and Hand Score" (DASH) and by quantitative ultrasound measurements of scar tissue volume. ⋯ There is no clear benefit of one incision technique over another. However, based on scar volume parameters, the significant faster recovery in the first month and the surgical ease of exposure and wound closure inclines us to favor the longitudinal incision (group 3) in future patients.

Randomized Controlled TrialMeasuring long radiographs affects the positioning of femoral components in total knee arthroplasty: a randomized controlled trial.
The aim of this study was to investigate if preoperative measurements of the femoral valgus angle (FVA) affected the mechanical alignment, individual component positions and clinical outcome in total knee arthroplasty (TKA). ⋯ Preoperative FVA measurement and following femoral distal cut adjustments did not affect overall leg alignment postoperatively, while positioning of femoral component was improved together with minor improvements in objective KSS subscale scores.

Case ReportsBilateral sternoclavicular joint dislocation due to sternal fracture: Is it a dislocation or a separation?
Traumatic bilateral sternoclavicular joint dislocation is very rare injury. In shoulder girdle injuries, anterior dislocation of the sternoclavicular joint accounts for 3 % and posterior sternoclavicular joint dislocation is lesser. ⋯ Authors experienced patient who has a bilateral anterior sternoclavicular joint dislocation caused by sternum fracture and anterior angulation, but intact relationship between ribs and clavicle. We report this case with satisfactory result.
