Fifty-two percent of distal femoral growth plate fractures had some form of growth disturbance. Twenty-two percent (112/506) of all distal femoral growth plate fractures developed a leg length discrepancy of greater than 1.5 cm. SH 1 fractures had the lowest incidence of growth disturbance (36%), whereas SH 4 fractures had the highest rate of growth disturbance at 64%. Although there is a greater incidence of growth disturbance in patients who were treated with fixation (58% versus 63%), there was a decreased incidence of significant growth disturbance (37% versus 27%).

In our case report, we describe a 55-year-old male patient with isolated foot drop due to an intraneural synovial ganglion. We successfully treated the lesion with decompression via epineurotomy combined with primary division of the recurrent articular branch of the common peroneal nerve (CPN). Compression neuropathies of the common peroneal nerve arise from a variety of causes. Intrinsic compression due to intraneural ganglion cysts of the CPN is rare. Previous reports of simple decompression of the cystic fluid have resulted in recurrence. The unified articular theory describes a pathway for fluid to fill from the proximal tibiofibular joint into the CPN via a recurrent articular branch. In our case, we divide this articular branch which we feel prevents recurrence.
