Multicenter StudyOpen reduction and internal fixation of proximal humeral fractures with use of the locking proximal humerus plate. Surgical technique.
The treatment of unstable displaced proximal humeral fractures, especially in the elderly, remains controversial. The objective of the present prospective, multicenter, observational study was to evaluate the functional outcome and the complication rate after open reduction and internal fixation of proximal humeral fractures with use of a locking proximal humeral plate. ⋯ Surgical treatment of displaced proximal humeral fractures with use of the locking proximal humeral plate that was evaluated in the present study can lead to a good functional outcome provided that the correct surgical technique is used. Because many of the complications were related to incorrect surgical technique, it behooves the treating surgeon to perform the operation correctly to avoid iatrogenic errors.

Multicenter StudyOperative management of distal radial fractures with 2.4-millimeter locking plates: a multicenter prospective case series. Surgical technique.
In the past decade, there has been a trend toward open reduction and internal fixation of unstable distal radial fractures. There are now more than thirty different implant designs specific for the fixation of distal radial fractures. A multicenter prospective study of a case series was conducted to determine the efficacy of the operative management of distal radial fractures stabilized with 2.4-mm locking plates. ⋯ Internal fixation of displaced distal radial fractures with implants featuring locking screw fixation can result in good-to-excellent outcomes with a limited number of complications.

ReviewOutcomes of single-row and double-row arthroscopic rotator cuff repair: a systematic review.
Arthroscopic rotator cuff repair is a common procedure that is gaining wide acceptance among orthopaedic surgeons because it is less invasive than open repair techniques. However, there is little consensus on whether to employ single-row or double-row fixation. The purpose of the present study was to systematically review the English-language literature to see if there is a difference between single-row and double-row fixation techniques in terms of clinical outcomes and radiographic healing. ⋯ There appears to be a benefit of structural healing when an arthroscopic rotator cuff repair is performed with double-row fixation as opposed to single-row fixation. However, there is little evidence to support any functional differences between the two techniques, except, possibly, for patients with large or massive rotator cuff tears (> or = 3 cm). A risk-reward analysis of a patient's age, functional demands, and other quality-of-life issues should be considered before deciding which surgical method to employ. Double-row fixation may result in improved structural healing at the site of rotator cuff repair in some patients, depending on the size of the tear.

Revision arthroscopic rotator cuff repair: repair integrity and clinical outcome.
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.

Thoracolumbar burst fractures treated with posterior decompression and pedicle screw instrumentation supplemented with balloon-assisted vertebroplasty and calcium phosphate reconstruction. Surgical technique.
The treatment of unstable thoracolumbar burst fractures with short-segment posterior spinal instrumentation without anterior column reconstruction is associated with a high rate of screw breakage and progressive loss of reduction. The purpose of the present study was to evaluate the functional, neurologic, and radiographic results following transpedicular, balloon-assisted fracture reduction with anterior column reconstruction with use of calcium phosphate bone cement combined with short-segment posterior instrumentation and a laminectomy. ⋯ The present study demonstrates that excellent reduction of unstable thoracolumbar burst fractures with and without associated neurologic deficits can be maintained with use of short-segment instrumentation and a transpedicular balloon-assisted reduction combined with anterior column reconstruction with calcium phosphate bone cement performed through a single posterior incision. The resultant circumferential stabilization combined with a decompressive laminectomy led to maintained or improved neurologic function in all patients with neurologic deficits, with a low rate of instrumentation failure and loss of correction.
