Randomized Controlled Trial Comparative StudyLateral entry compared with medial and lateral entry pin fixation for completely displaced supracondylar humeral fractures in children. A randomized clinical trial.
Closed reduction and percutaneous pin fixation is the treatment of choice for completely displaced (type-III) extension supracondylar fractures of the humerus in children, although controversy persists regarding the optimal pin-fixation technique. The purpose of this study was to compare the efficacy of lateral entry pin fixation with that of medial and lateral entry pin fixation for the operative treatment of completely displaced extension supracondylar fractures of the humerus in children. ⋯ Therapeutic Level I.

Revision of a failed total hip arthroplasty with massive acetabular bone loss and pelvic discontinuity is a reconstructive challenge. This report presents the mid-term to long-term results of revision total hip arthroplasty with a custom-made porous-coated triflange acetabular prosthesis in a consecutive series of patients with pelvic discontinuity. ⋯ Therapeutic Level IV. See Instructions to Authors for a complete description of levels of evidence.

Isolated arthroscopic biceps tenotomy or tenodesis improves symptoms in patients with massive irreparable rotator cuff tears.
Lesions of the long head of the biceps tendon are often associated with massive rotator cuff tears and may be responsible for shoulder pain and dysfunction. The purpose of this study was to evaluate the clinical and radiographic outcomes of isolated arthroscopic biceps tenotomy or tenodesis as treatment for persistent shoulder pain and dysfunction due to an irreparable rotator cuff tear associated with a biceps lesion. ⋯ Therapeutic Level III. See Instructions to Authors for a complete description of levels of evidence.

Early results of conversion of a failed femoral component in hip resurfacing arthroplasty.
A theoretical advantage of resurfacing arthroplasty of the hip is that a failed femoral component can be safely and successfully revised to a total hip arthroplasty. To our knowledge, this advantage has not been demonstrated to date. ⋯ Therapeutic Level III. See Instructions to Authors for a complete description of levels of evidence.

The impact of the accreditation council for graduate medical education work-hour regulations on the surgical experience of orthopaedic surgery residents.
The advent of the eighty-hour workweek regulations generated a great deal of controversy over the potential loss of operative experience for general surgery and surgical specialty residents. We believed an investigation to review the operative experience of orthopaedic surgery residents before and after the adoption of the Accreditation Council for Graduate Medical Education duty-hour guidelines would provide important information in this debate. ⋯ Although many aspects of surgical training may be affected by the new work-hour restrictions, our review of the operative experience of orthopaedic surgery residents at a single institution demonstrated no significant differences before and after the implementation of the eighty-hour workweek.
