Current sports medicine reports, 20(5), 266-270.More infoThe principles and management of simple elbow dislocations have evolved over time. In the past, a conservative approach of immobilization and slow rehabilitation were used. More modern treatments emphasize an understanding of the soft tissues about the elbow joint and prescribe an aggressive approach to regaining motion. Elbow stiffness is a common effect of the injury. We outline our treatment principles in a series of high school wrestlers with simple elbow dislocation. The ultimate goal is to return to sport in a safe but early timeframe. We recommend a brief period of immobilization with close follow-up and no motion restrictions after immobilization is removed. This review and case series emphasize the importance of aggressive but safe return to sport in high school wrestlers with an elbow dislocation.

Clinical orthopaedics and related research, 478(4), 734-738.More infoMany studies have evaluated the reverse sural fasciocutaneous flap for coverage of wounds on the distal lower extremity, and many of these have focused on younger, healthy patients. However, to our knowledge, there has been no dedicated study focusing on older patients. We believe there is a generalized concern about performing these procedures in older patients because of microvascular changes associated with aging.

Skeletal radiology, 44(2), 165-77.More infoPrimary osteoarthritis (OA) involving the thumb carpometacarpal (CMC) joint is a common and frequently debilitating disease. Clinical examination and radiographs are usually sufficient for diagnosis; however, familiarity with the cross-sectional anatomy is useful for diagnosis of this condition. The most widely used classification system for the radiographic staging of thumb carpometacarpal joint OA was first presented by Eaton and Littler, ranging from mild (stages I and II) to severe (stage IV) disease. If conservative treatment fails, surgical treatment is considered. A variety of surgical techniques have been developed and implemented for the management of this pervasive and disabling condition. The purpose of this article is to review the anatomy of the basal joints of the thumb, pathophysiology, preoperative imaging, and various surgical techniques that are utilized in the treatment of OA of the basal joints of the thumb with emphasis on normal postoperative radiographic findings and possible postoperative complications.

Orthopedics, 38(12), e1059-64.More infoSoft tissue coverage of distal medial ankle wounds is a challenging problem in orthopedic surgery because of the limited local tissues and prominent instrumentation. Traditionally, these wounds required free tissue transfer to achieve suitable coverage and subsequent bony union. To better respect the reconstructive ladder and to avoid the inherent difficulty of free flap coverage, rotational flaps have been used to cover these wounds. Both sural fasciocutaneous flaps and rotational fasciocutaneous perforator (propeller) flaps have been described for distal medial soft tissue coverage. The authors performed a retrospective chart review of patients who underwent distal medial leg coverage with the use of either sural flaps or rotational fasciocutaneous perforator flaps. The authors identified 14 patients by Current Procedural Terminology code who met the study criteria. The average age and degree of medical comorbidities were comparable in the 2 groups. The authors reviewed their medical records to evaluate fracture healing, flap size, complications, and return to normal shoe wear. All 7 sural flaps healed without incident, with underlying fracture healing. Of the 7 perforator flaps, 6 healed without incident, with underlying fracture healing. One perforator-based flap was complicated by superficial tip necrosis and went on to heal with local wound care. All patients returned to normal shoe wear. Both sural artery rotational flaps and posterior tibial artery-based rotational flaps are viable options for coverage of the distal medial leg. Coverage can be achieved reliably without microsurgery, anticoagulation, or monitoring in the intensive care unit.

Seminars in musculoskeletal radiology, 16(2), 159-73.More infoThe scaphoid is the most commonly fractured carpal bone, with frequent complications that are predisposed by its anatomical location, anatomical configuration (shape and length), and vascular supply. The most common mechanism of injury is a fall onto an outstretched hand. Imaging plays a significant role in the initial evaluation and treatment of scaphoid fractures and their complications. Radiography should be the first imaging modality in the initial evaluation and follow-up of scaphoid fractures. Computed tomography with its superb spatial resolution enables better visualization and characterization of the fracture line, and the amount of displacement and angulation of the fracture fragments. Using the metal reduction artifact with computed tomography allows good follow-up of scaphoid fractures despite surgical hardware. Magnetic resonance imaging without contrast is the imaging modality of choice for depiction of radiographically occult scaphoid fracture, bone contusion, and associated soft tissue injury; contrast-enhanced imaging aids assessment of scaphoid fracture nonunion, osteonecrosis, fracture healing after bone grafting, and revitalization of the necrotic bone after bone grafting. Proper identification and classification of scaphoid fracture and its complications is necessary for appropriate treatment. This article describes the normal anatomy, mechanism of injury, and classification of stable and unstable fractures, together with the imaging and treatment algorithm of scaphoid fractures and their complications with an emphasis on magnetic resonance imaging.

Techniques in hand & upper extremity surgery, 11(2), 163-7.More infoManagement of bone loss, particularly in the face of open or contaminated wounds, presents a reconstructive challenge. Polymethylmethacrylate impregnated with antibiotics has been used successfully in the treatment of infected total joint arthroplasty and open fractures. The cement delivers high-dose local concentrations of antibiotics while filling a space. This article presents our use of an antibiotic-impregnated cement spacer for bone loss in the forearm or hand in the face of open or infected wounds. The cement spacer fills a potential space, prevents the involution of the surrounding soft tissue, and delivers appropriate antibiotics. When the spacer is removed, the remaining sheath serves to hold and contain the cancellous bone graft.

Clinical orthopaedics and related research, 76-81.More infoFunctional outcomes and complications experienced by adult patients who underwent iliac crest bone grafting were evaluated to assess the effect of bone grafts on patient function. In addition to retrospective chart reviews, patients completed the Sickness Impact Profile and a detailed questionnaire on pain. One hundred ninety-two patients met study inclusion criteria. Major complications were recorded in four (2.4%) patients in whom infections developed requiring readmission. Thirty-seven (21.8%) patients had minor complications. One hundred nineteen of 170 patients were available for followup; of these 119 patients, 87 (73.1%) returned completed questionnaires. Thirty-three of 87 (37.9%) patients reported pain 6 months postoperatively. The incidence of pain decreased with time, with 16 of 87 (18.7%) patients continuing to report pain more than 2 years postoperatively. Proportionately more spine patients reported pain at all time points. The mean Sickness Impact Profile score for patients completing questionnaires was nine, suggesting most patients were functioning well 2 years postoperatively. The morbidity of iliac crest grafting remains substantial. Pain symptoms in this study sample seemed to last longer in more patients than earlier series have indicated. Minimizing muscle dissection around donor sites and the advent of bone graft substitutes may help alleviate these problems.
