Anatomic variations in the lateral femoral cutaneous nerve with respect to pediatric hip surgery.

Variations were documented in the course of the lateral femoral cutaneous nerve (LFCN) in the upper thigh relative to anatomic landmarks in 22 adult cadavers using the Smith-Petersen incision for the anterior approach to the hip. Distances from the anterior superior iliac spine (ASIS) to the point of nerve entry into the thigh were normalized as percentages of the distance from the ASIS to the pubic tubercle (PT) to relate the data to small children. In all cases, the LFCN passed deep to the inguinal ligament, entering the thigh a mean of 2.

Knee extensor mechanism reconstruction with medial gastrocnemius flap.

Infection after osteotomy of the tibial tubercle can lead to nonunion and chronic osteomyelitis of the tuberosity. Radical debridement for control of infection in this situation may require resection of the sequestrated tuberosity fragment with the resultant problem of disruption of the extensor mechanism of the knee. A review of the literature failed to identify any description of successful treatment of such a complication.
