Screw Impingement Causing Massive Swelling of the Sciatic Nerve: A Case Report.

Sciatic nerve (SN) injuries after hip fracture dislocation are described and are not uncommon. Several factors can lead to SN injury after hip surgery; among other factors, screw plates of synthesis materials can immigrate and lead to nerve impingement. We report a case of a 22-year-old male with a history of posterior wall fracture and hip dislocation after a motorway accident. Ultrasonography showed massive swelling of the SN with a cross-sectional area measured at 1.50 cm2 upstream to screw impingement. The reoperation option was judged too risky by the orthopedic surgeons; currently, the patient is undergoing platelet-rich plasma (PRP) injections around the nerve swelling and to the lifter muscles of the foot.
