Distal Aspect of Biceps ä Operative treatment of both partial and complete distal biceps ruptures results in better outcomes compared with nonoperative care, although the optimal technique and fixation are yet to be determined. ä Nonoperative management is an acceptable treatment for patients willing to accept some loss of forearm supination and elbow flexion strength as well as changes in endurance and cosmesis.

It was hypothesized that those who failed surgical repair would have increased posterior glenoid bone loss and decreased glenoid width. Methods: Athletes greater than 18 years of age with unidirectional posterior instability treated with arthroscopic repair were evaluated at 2 year minimum follow-up. Traditional MRIs measurements from nineteen patients who failed arthroscopic posterior shoulder capsulolabral repair were compared with 56 patients who did not. MRIs were then manually reformatted and these measurements were repeated as well as recently described measures of defect slope, bone loss angle, and defect length. Results: Glenoid width loss and percent glenoid bone loss were significantly greater on both the corrected and non-corrected M...

Vascular complications following pediatric both bone forearm fractures are rare. This article presents a case of a closed both-bone forearm fracture in a child treated with closed reduction and casting.

The vast majority of these result in large amounts of bone loss, resorption, and issues with retained hardware, and there is minimal literature that assesses outcomes of revision surgery following a failed Latarjet. The objective of this study was to determine the outcomes of patients who underwent revision surgery for a recurrent shoulder instability after a failed Latarjet procedure. Methods: All consecutive patients who presented with recurrent anterior shoulder instability after a Latarjet procedure were prospectively enrolled. Patients were included if they had a prior Latarjet, and a history and physical examination findings consistent with recurrent anterior shoulder instability. Patients were excluded if they had prior neurologic injury, a seizure disorder, bone graft requirements to the humeral head, or findings of multidirectional or posterior instability. His...

While there are numerous descriptions of unique arthroscopic knots, selection and correct implementation is critical for adequate soft tissue fixation and successful patient outcomes. Specifically, the Roeder knot, a type of locking sliding knot, with 3 alternating half hitches, has been described to provide the loop and knot security among other sliding knot techniques. Therefore, the Roeder knot has emerged as a preferred knot tying technique amongst orthopedic surgeons, especially in the setting of arthroscopic shoulder stabilization procedures. In this case, we describe the basic fundamentals of performing a Roeder knot with 3 alternating half hitches to anchor the labrum to the glenoid in the setting of an arthroscopic Bankart repair.

Methods: A total of 217 consecutive three-dimensional (3D) Computed Tomography (CT) scans were reviewed for the presence and measurement of Hill-Sachs volume and location. Hill-Sachs volume was measured by measuring the size of the Hill-Sachs defect in sequential CT images and a 3D model was created to measure the volume of the defect using Osirix (Osirix Imaging Software, Osirix-viewer.com). The Hill-Sachs lesion was then quantified in terms of both location and size. Further, older classification systems were applied to the data to draw comparison. Location of the lesion was measured by utilizing anterior and posterior margins of the lesion in relation to the biceps groov...

The purpose of this study is to quantify the in-patient mortality rates and associated demographic risk factors for patients undergoing a TSA from 2005 to 2011 using a comprehensive Medicare registry database. We conducted a retrospective review of the Medicare database within the PearlDiver database. The PearlDiver database is a publicly available Health Insurance Portability and Accountability Act-compliant national database that captures 100% of the Medicare hospital data for TSA between 2005 and 2011. Using International Classification of Diseases, Ninth Revision codes for TSA we identified a dataset of patients undergoing TSA as well as a subset of those for whom there was a death discharge (i.e., in-patient death). Risk for this outcome was further quantified by age, gender and year. Linear regression was performed to identify risk factors for the primary outcome. A total of 101,323 patients und...

The complexity of the scapula provides the shoulder girdle muscle origins to direct in-line vectors to maximize pull in physiologic directions with their insertion on the humerus. The orientation and shallow depth of the glenoid, with the corresponding large articular surface area of the humerus, allow a range of motion that is unlike any other joint or joint complex.

Retrospective review of predeployment surgical plans, operative case logs, and after-action reports from United States Naval Ship (USNS) Mercy humanitarian deployments from 2006 to 2012. The USNS Mercy hospital ship. We enrolled 24 surgical residents from different surgical specialties including general surgery, obstetrics and gynecology, urology, otolaryngology, and ophthalmology. During 4 planned deployments (2006-2012), 2887 surgical procedures were performed during 20 humanitarian missions conducted by the USNS Mercy in 9 different Southeast Asian countries. Of all the general surgery eligible procedures performed, 1483 (79%) were defined categories under the current general surgery Accreditation Council for Graduate Medical Education guidelines, including abdominal (31%); skin, soft tissue, and breast (21%); ear, nose, and throat (20.5%); plastic surgery (15.5%); and pediatric (12%) cases. The number of surgical cases completed by each resident ranged from 30 to 67 cases over a period of 4 to 6 weeks during the overseas humanitarian rotation. The US Navy's humanitarian experience provides a unique educational opportunity for young military surgeons to experience various global health systems, diverse cultures, and complex logistical planning without sacrificing the breadth and depth of surgical training. This model may provide a framework to develop future international electives for other general surgery training programs.
