Clinically Relevant Elbow Anatomy and Surgical Approaches
The elbow is primarily a ginglymus or hinge joint but consists of three bony articulations including ulnohumeral, radiocapitellar and radioulnar motions. In elbow extension, contributions to valgus stability remain fairly constant that includes the bone architecture, anterior capsule, and medial ulnar collateral ligament.
Trabecular Bone Microarchitecture and Characteristics in Different Regions of the Glenoid
Success of shoulder surgery depends on implant fixation to the glenoid trabecular bone. The purpose of this study was to evaluate the anatomic characteristics of the normal glenoid trabecular bone microarchitecture to help assist in implant design and provide data for finite element analyses. Eight cadavers without evidence of ...
Inferior Glenosphere Placement Reduces Scapular Notching in Reverse Total Shoulder Arthroplasty
Scapular notching is a common complication after reverse shoulder arthroplasty and has been associated with poor clinical outcomes. Factors associated with notching include neck shaft angle and glenosphere position. The goal of this study was to evaluate the incidence of notching with an eccentric glenosphere that allows for...
Managing and recognizing complications after treatment of acromioclavicular joint repair or reconstruction
Complications of the acromioclavicular joint injuries can occur as a result of the injury itself, conservative management, or surgical treatment. Fortunately, the majority of acromioclavicular surgeries utilizing modern techniques and instrumentation result in successful outcomes. However, clinical failures do occur with...
Management of complications after reverse shoulder arthroplasty
Reverse total shoulder arthroplasty (RTSA) has become the treatment of choice for patients with rotator cuff arthropathy. Complication rate after RTSA has been reported to be three to five times that of conventional total shoulder arthroplasty. Intraoperative and postoperative complications include neurological injury, infection...
A Comparison of the Lateral Decubitus and Beach-chair Positions for Shoulder Surgery: Advantages and Complications
Arthroscopic or open shoulder surgery can be performed using the lateral decubitus or beach-chair position. Advantages of the lateral decubitus position include better visualization and instrument access for certain procedures and decreased risk for cerebral hypoperfusion. Complications associated with this position include...
Management of Propionibacterium acnes infection after shoulder surgery
Propionibacterium acnes (P. acnes) is a gram-positive anaerobic bacillus commonly isolated from the flora of the face, chest, and axilla region. It has emerged as a major pathogen responsible for postoperative shoulder infections after both arthroscopy and arthroplasty procedures. Patients with P. acnes shoulder infection typically...
Bilateral Simultaneous Anterior Cruciate Ligament Injury: A Case Report and National Survey of Orthopedic Surgeon Management Preference
Unilateral anterior cruciate ligament (ACL) tear is a common injury seen by sports medi-cine orthopedic surgeons. However, a bilateral simultaneous ACL injury is extremely rare and has been reported only three times in the liter-ature. We present a young female skier with simultaneous bilateral ACL tears that were managed with staged ACL reconstruction. We then conducted a nationwide survey (United States) to determine the...
Prevalence of Internet and Social Media Usage in Orthopedic Surgery
Prior studies in other specialties have shown that social networking and Internet usage has become an increasingly important means of patient communication and referral. The purpose of this study is to evaluate the prevalence of Internet or social media usage in new patients referred to a major academic orthopedics center...
Vancomycin-bearing Synthetic Bone Graft Delivers rhBMP-2 and Promotes Healing of Critical Rat Femoral Segmental Defects
Background: Bone grafts simultaneously delivering therapeutic proteins and antibiotics may be valuable in orthopaedic trauma care. Previously, we developed a poly(2-hydroxyethyl methacrylate)-nanocrystalline hydroxyapatite (pHEMA-nHA) synthetic bone graft that, when preabsorbed with 400-ng rhBMP-2/7, facilitated the...
