Anomalous superficial peroneal nerve with higher division: a case report

The superficial peroneal nerve is one of the terminal branch of common peroneal nerve. There are reports in the available literature about the variant course and distribution of this nerve. The variations of the above nerve are important and provide important information to surgeons during dissection of lower limb. In the present case a rare higher division of superficial peroneal nerve into medial and lateral branches in the leg was seen in an adult male cadaver in left lower limb. Awareness of anatomical variations of superficial peroneal nerve presented here becomes important to avoid injury in clinical situations like pain over the lateral malleolus

An unorthodox innervation of the gluteus maximus muscle and other associated variations: A case report

Knowledge of peripheral nerve morphology, location, and variation is important for facilitating appropriate diagnosis and intervention. We present a unique case of absence of the inferior gluteal nerve and high division of the sciatic nerve. In this instance, the common peroneal nerve was found piercing the piriformis muscle and emerging distally in the form of two trunks: thin medial and thick lateral. The medial trunk presented an interesting course, supplying the gluteus maximus muscle before joining the lateral trunk to form the common peroneal nerve. Additionally, the arteria nervi ischiadisci was also observed accompanying and supplying the tibial nerve passing inferior to the piriformis. These variations are important for clinicians and surgeons for some radiological diagnoses and surgical procedures in the lower limb
