Few preresidency variables correlate to success during an orthopaedic residency.

Familial tumoral calcinosis has a varied natural history; some patients have an unrelenting course, while others may experience quiescent periods. The GALNT3 gene is responsible for the hyperphosphatemic form as seen in this family. Molecular testing may be of benefit to members of affected families, and future studies may help to explain the phenotypic variability among affected individuals. No medical or surgical treatment plan seemed to be effective for controlling the lesions in this family.

Posterior sternoclavicular joint dislocations and epiphyseal fractures are relatively rare injuries. We present a case report of a 16-year-old male who presented with a 10-day delay in diagnosis. The medial clavicular fragment was widely displaced and rested against the cervical vertebral body. Despite the degree of displacement, the patient had very few symptoms, and the diagnosis was not appreciated in the emergency department and became apparent at 10-day clinic follow-up. Treatment consisted of attempts at closed reduction, which were not successful. Open reduction was performed and the repair done with strong sutures. At 1-year follow-up the patient is doing well without any symptoms. A literature review consisting of anatomy, ossification patterns, classification systems, diagnosis and associated symptoms, imaging recommendations, treatment recommendations, outcomes, and complications is included.

Smooth Kirschner wires (K-wires) are frequently used in pediatric orthopaedics; however, the infection rate associated with these devices is not known. A retrospective study on infection rates in pediatric patients who had fractures treated with percutaneous smooth K-wire fixation was performed. A total of 202 patients with an average age of 9.7 years were included in the study. Upper extremity fractures made up 93% of the cases. The overall infection rate was 7.9%. The classification system of Green was used to describe major and minor infections. There were 16 infections noted; 12 (5.9%) of these were minor, and 4 (2%) were major. Infection rates did not correlate with length of fixation. There was also no correlation of increased infection rates with open fractures or fractures that required open reduction. The infection rates associated with the use of smooth K-wires in pediatric fracture patients is low. The major infection rate is only 2% and does not correlate to length of fixation or type of fracture.
