Both lower extremities of 10 cadavers (20 specimens) were dissected to delineate the course of the saphenous nerve and its two major divisions (sartorial and infrapatellar branches). The course of the saphenous nerve followed the standard text description, except at the point in the sartorius muscle where the infrapatellar branch exited to become a subcutaneous structure. ⋯ Since 69% of a group of 75 patients found altered sensation significant after routine sectioning of the infrapatellar nerve following medial meniscectomy, a group of surgeons at the University of Michigan is now protecting the infrapatellar branch of the saphenous nerve at operation. Early results on a small number of patients indicate that no alteration in sensation occurs if the nerve is carefully retracted.

Ulnar nerve entrapment at the elbow has been described in the literature. This paper deals with 19 skeletally mature baseball players with ulnar nerve entrapment who underwent surgery for correction of the problem. ⋯ Ulnar nerve entrapment is thought to represent one syndrome in a spectrum of diseases involving the medial side of the elbow in baseball players. The lesion is amenable to surgery.

Tibial tubercle fractures are uncommon and rarely occur after closure of the proximal tibial epiphysis. A study of 15 such injuries, all unilateral, showed the age range to be from 12 to 16 years. ⋯ No early complications occurred, and no later deformities, such as genu recurvatum as reported by Blout, were detected. All patients returned to normal activity including in some cases, varsity athletics.
