Are dropped osteoarticular bone fragments safely reimplantable in vivo?
There are limited data detailing the appropriate management of nondisposable autologous osteoarticular fragments that have been contaminated by the operating room floor. The goal of the present study was to perform a comprehensive, three-phase investigation to establish an appropriate intraoperative algorithm for the management of the acutely contaminated, but nondisposable, autologous osteoarticular bone fragment. ⋯ The majority of osteochondral fragments that contact the operating room floor produce positive bacterial cultures. Five minutes of cleansing with a 10% povidone-iodine solution followed by a normal saline solution rinse appears to provide the optimal balance between effective decontamination and cellular toxicity for dropped autologous bone in the operative setting.

Internal fixation of type-C distal femoral fractures in osteoporotic bone: surgical technique.
Fixation of distal femoral fractures remains a challenge, especially in osteoporotic bone. This study was performed to investigate the biomechanical stability of four different fixation devices for the treatment of comminuted distal femoral fractures in osteoporotic bone. ⋯ The findings of this study support the concept that, for intramedullary nails, the kind of distal interlocking pattern affects the stabilization of distal femoral fractures. Four-screw distal locking provides the highest axial stability and nearly comparable torsional stability to that of the angular stable plate; the four-screw distal interlocking construct was found to have the best combined (torsional and axial) biomechanical stability.

Revision arthroscopic rotator cuff repair: repair integrity and clinical outcome: surgical technique.
Literature regarding the outcomes of revision rotator cuff repair is limited. The purposes of the present study were to report the tendon repair integrity and clinical outcomes for a cohort of patients following revision arthroscopic rotator cuff repair and to examine factors related to tendon healing and the influence of healing on clinical outcomes. ⋯ Revision arthroscopic rotator cuff repair results in reliable pain relief and improvement in shoulder function in selected cases. Approximately half of the revision repairs can be expected to be intact at a minimum of one year following surgery. Patient age and the number of torn tendons are related to postoperative tendon integrity. The postoperative integrity of the rotator cuff can have a significant influence on shoulder abduction strength and the Constant score.

Concomitant arthroscopic SLAP and rotator cuff repair: surgical technique.
The outcomes of combined arthroscopic repairs of a SLAP (superior labral anterior-posterior) lesion and a rotator cuff tear are not known. We compared the outcomes in a cohort of patients who had undergone concomitant arthroscopic repairs of a SLAP lesion and a rotator cuff tear with those in a cohort of patients with a stable biceps anchor who had undergone an isolated rotator cuff repair. We hypothesized that the results would be similar between the two cohorts with respect to the range of motion and preoperative and postoperative function. ⋯ Controversy surrounds the treatment of a SLAP lesion with concomitant treatment of a full-thickness rotator cuff tear. This study suggests that, in middle-aged patients, the results of combined SLAP lesion and rotator cuff repair can be comparable with those achieved with rotator cuff repair alone.
