Multicenter Study Comparative StudyA prospective multicenter study of Legg-Calvé-Perthes disease: functional and radiographic outcomes of nonoperative treatment at a mean follow-up of twenty years.
Long-term studies have indicated good outcomes for most patients with Legg-Calvé-Perthes disease. However, clinical experience suggests that less favorable outcomes are common. We sought to prospectively document pain and function in a cohort of adults who had previously been treated nonoperatively for Legg-Calvé-Perthes disease. ⋯ Pain, arthritis, and ongoing hip dysfunction are common in patients with Legg-Calvé-Perthes disease that was treated nonoperatively. Hips rated as Stulberg type III or IV more frequently had poor or fair outcomes on the IHS and NAHS (61% and 72% for type III and 77% and 60% for type IV). Patients with a lateral pillar type of B, B/C, or C frequently had pain and radiographic evidence of osteoarthritis. Clinical signs of femoroacetabular impingement were associated with pain and with lower functional scores. This prospective study establishes a modern benchmark for outcomes following nonoperative, weight-bearing treatment of Legg-Calvé-Perthes disease.

Anterior shoulder instability associated with coracoid nonunion in patients with a seizure disorder.
An association between coracoid fracture and glenohumeral instability with both a seizure disorder and the subsequent development of coracoid nonunion has not previously been recognized. This is clinically important as patients with a seizure disorder and glenohumeral instability frequently require a primary osseous reconstructive procedure, such as coracoid osteotomy and transfer to the anterior glenoid rim (the Bristow-Latarjet procedure), to address glenoid osseous deficiency. We report on coracoid fracture nonunion in five patients with a seizure disorder and anterior glenohumeral instability and discuss the implications for surgical treatment. ⋯ We recommend having a high index of suspicion of coracoid fracture when treating patients with a seizure disorder who have anterior glenohumeral instability. In these patients, preoperative computed tomographic images allow the diagnosis of a coracoid nonunion to be made prior to surgery and help to determine whether there is sufficient intact coracoid bone to allow a Bristow-Latarjet procedure to be performed.

Detection of total hip prostheses at airport security checkpoints: how has heightened security affected patients?
The sensitivity of airport security screening measures has increased substantially during the past decade, but few reports have examined how this affects patients who have undergone hip arthroplasty. The purpose of this study was to determine the experiences of patients who had hip prostheses and who passed through airport security screenings. ⋯ This study provides interesting and critical information that allows physicians to understand the real-world implications of implanted orthopaedic devices for patients who are traveling where there has been heightened security since September 11, 2001. Patients should be counseled that they should expect delays and be prepared for such inconveniences, but that these are often only momentary. This information could relieve some anxiety and concerns that patients may have prior to traveling.

Comparative StudyComparative effect of orthosis design on functional performance.
High-energy extremity trauma is common in combat. Orthotic options for patients whose lower extremities have been salvaged are limited. A custom energy-storing ankle-foot orthosis, the Intrepid Dynamic Exoskeletal Orthosis (IDEO), was created and used with high-intensity rehabilitation as part of the Return to Run clinical pathway. We hypothesized that the IDEO would improve functional performance compared with a non-custom carbon fiber orthosis (BlueRocker), a posterior leaf spring orthosis, and no brace. ⋯ Use of the IDEO significantly improves performance on validated tests of agility, power, and speed. The majority of subjects initially considering amputation favored limb salvage after this noninvasive intervention.

Assessment of musculoskeletal physical examination skills and attitudes of orthopaedic residents.
Although the musculoskeletal physical examination is an essential part of patient encounters, we believe that it is underemphasized in residency education and that residents' physical examination skills may be lacking. We sought to assess attitudes regarding teaching of the physical examination in orthopaedic residencies, to assess physical examination knowledge and skills among residents, and to develop a method to track the skill level of residents in order to improve our physical examination curriculum. ⋯ We have exposed a deficiency in the physical examination knowledge and skills of our residents. Although the musculoskeletal physical examination is a vital practice component, our data indicate that it is likely underemphasized in training. Clinic time alone is likely insufficient for the teaching and learning of the musculoskeletal physical examination.
