Can larger-bodied cemented femoral components reduce periprosthetic fractures? A biomechanical study.
The risk for late periprosthetic femoral fractures is higher in patients treated for a neck of femur fracture compared to osteoarthritis. It has been hypothesised that osteopaenia and consequent decreased stiffness of the proximal femur are responsible for this. We investigated whether a femoral component with a bigger body would increase the torque to failure in a biaxially loaded composite Sawbone model. ⋯ The use of large body polished tapered cemented stems for neck of femur fractures increases the torque to failure in a biomechanical model and therefore is likely to reduce late periprosthetic fracture risk in this vulnerable cohort.

Comparison of treatment of oblique and spiral metacarpal and phalangeal fractures with mini plate plus screw or screw only.
We aimed to compare results of treatment of oblique-spiral metacarpal and phalangeal fractures with screw only or mini plate plus screw, respectively. ⋯ Treatment with mini plate plus screw should be avoided in spiral and oblique phalangeal fractures, and fixation should be done with screw only with a short surgical incision and dissection. On the other hand, treatment with mini plate plus screw should be preferred in patients with spiral and oblique metacarpal fractures, especially in those who work in occupations requiring higher physical strength.

Thumb fingertip reconstruction with palmar V-Y flaps combined with bone and nail bed grafts following amputation.
The aim of treating thumb fingertip amputations with no indication for replantation is to reestablish functional and esthetic properties. ⋯ We believe that the combination of palmar V-Y flap and bone and nail bed grafts provides a distinct advantage over other choices. It improves function when replantation is not an option.

Effects of anesthetic technique on blood loss and complications after simultaneous bilateral total knee arthroplasty.
Anesthetic technique affects perioperative outcomes, but less was known in simultaneous bilateral total knee arthroplasty (BTKA). A single center, retrospective analysis was carried out to prove the hypothesis that utilization of regional anesthesia would result in favorable perioperative outcomes. ⋯ Patients who underwent simultaneous BTKA under RA had lesser blood loss and lower complication rate than GA. The impact of RA can be further exploited to improve perioperative outcomes of simultaneous BTKA in addition to various other interventions.

Restoring optimal strength and biomechanics of a pathologic shoulder knowledge of activity patterns of healthy glenohumeral muscles is mandatory. Yet, data on normal shoulder muscle activity are not always conclusive. The study was undertaken (a) to evaluate muscle activity patterns in the healthy shoulder using surface and fine-wire electromyography (EMG), and (b) to assess method's suitability in the clinical setting especially regarding painfulness and practicability. ⋯ Basic Science, Electrodiagnostic Study.
