Occupational Radiation Exposure During Intraoperative 3-Dimensional Fluoroscopy in Pelvis and Acetabular Surgery.

Objectives: To quantify the occupational radiation exposure with a 3-dimensional (3D) fluoroscopic machine during routine use in pelvic and acetabular surgery and to determine whether the additional radiation exposure encountered with the 3D fluoroscopic spin is within previously accepted limits.

Design: Prospective cohort study.

Setting: Level I trauma center.

Treatment of Acromioclavicular Joint Instability With a Tunnel-Free Reconstruction Technique.

Acromioclavicular joint injuries are a common shoulder injury encountered by orthopaedic surgeons. Many different surgical techniques have been described for the operative treatment of these injuries with no single, clear gold standard technique on which surgeons agree. Among the most common complications after surgical management of acromioclavicular injuries are loss of reduction, infection, fracture of clavicle or coracoid, and need for reoperation.

The Utility of the Hyperinlet View in Posterior Fixation of Pelvic Ring Injuries.

Percutaneous pelvic fixation has evolved into a widely used, safe, and effective treatment option in the management of pelvic ring injuries. Proper preoperative and intraoperative radiographic evaluation of these injuries is critical to ensure safe placement of fixation of the pelvis. Traditional intraoperative views for posterior pelvic ring fixation include the pelvic inlet and outlet views.

Pilot Study Analysis of Serum Cytokines to Differentiate Pediatric Septic Arthritis and Transient Synovitis.

Background: In pediatric patients, the presentation of the nontraumatic acutely painful joint/limb poses a diagnostic dilemma due to the similarity of presentations of the most likely diagnoses [septic arthritis (SA), transient synovitis (TS), osteomyelitis]. Current tools employed to differentiate these diagnoses rely on nonspecific inflammatory markers, radiologic imaging, and arthrocentesis. Diagnostic algorithms utilizing these clinical, radiographic, and biochemical parameters have produced conflicting results.

Total shoulder arthroplasty with an anterior-offset humeral head in patients with a B2 glenoid.

Background: To address severe posterior subluxation associated with the Walch B2 glenoid deformity, the eccentricity of the prosthetic humeral head can be reversed, allowing the humerus to remain in a relatively posterior position while the prosthetic humeral head remains well-centered on the glenoid. This study describes the short-term outcomes after anatomic total shoulder arthroplasty (TSA) using this technique.

Methods: We retrospectively reviewed a consecutive series of patients with a B2 glenoid who underwent TSA with the prosthetic eccentric humeral head rotated anteriorly for excessive posterior subluxation noted intraoperatively.

The Arterial Anatomy of the Lateral Ligament Complex of the Ankle: A Cadaveric Study.

Background: Ankle sprains are the most common musculoskeletal injury in the United States. Chronic lateral ankle instability can ultimately require operative intervention to decrease pain and restore stability to the ankle joint. There are no anatomic studies investigating the vascular supply to the lateral ankle ligamentous complex.

Patient Preferences for the Treatment of Shoulder and Proximal Biceps Disorders Are Associated With Patient Age, Race, Sex, and Activity Level.

Background: Patient preference information has become increasingly more important in clinical decision making.

Purpose: To assess patient preferences when making treatment decisions in the shoulder to determine which features are more important according to patient age, race, activity level, and sex.

Study Design: Cross-sectional study; Level of evidence, 3.

Total shoulder arthroplasty in patients with a B2 glenoid addressed with corrective reaming.

Background: This study describes the short-term functional and radiographic outcomes after total shoulder arthroplasty (TSA) in shoulders with a B2 glenoid deformity addressed with corrective reaming.

Methods: We conducted a retrospective series of consecutive patients who underwent TSA with a Walch B2 glenoid quantified by computed tomography scan. All glenoid deformities were addressed using partially corrective glenoid reaming.

The Arterial Anatomy of the Deltoid Ligament: A Cadaveric Study.

Background: There is an increasing interest in the operative treatment of deltoid ligament disruption in the setting of chronic ankle instability. Understanding the vascular anatomy of the deltoid complex is beneficial when considering operative procedures on the medial ankle and may provide insight into factors that lead to chronic deltoid insufficiency and ankle instability.

Methods: Thirty-two pairs of cadaveric specimens (64 total legs) were amputated below the knee, and the tibialis anterior, tibialis posterior, and peroneal arteries were injected with India ink and Ward's blue latex.

Quality of internet health information on thumb carpometacarpal joint arthritis.

Introduction: The Internet has become a heavily used source of health information. No data currently exists on the quality and characteristics of Internet information regarding carpometacarpal (CMC) arthritis.

Methods: The search terms "cmc arthritis," "basal joint arthritis," and "thumb arthritis" were searched using Google and Bing.

Evaluation of the content and accessibility of web sites for accredited orthopaedic sports medicine fellowships.

Background: The Internet is a common source of information for orthopaedic residents applying for sports medicine fellowships, with the web sites of the American Orthopaedic Society for Sports Medicine (AOSSM) and the San Francisco Match serving as central databases. We sought to evaluate the web sites for accredited orthopaedic sports medicine fellowships with regard to content and accessibility.

Methods: We reviewed the existing web sites of the ninety-five accredited orthopaedic sports medicine fellowships included in the AOSSM and San Francisco Match databases from February to March 2012.

Examining Internet resources on gender differences in ACL injuries: what patients are reading.

Background: The Internet is a popular and powerful resource used by both clinicians and patients. However, medical information on the Internet is often unregulated, biased, and of poor quality. Given the frequency of ACL injuries in young women, this topic was used as a case study to examine the information available to patients on the Internet.
