Lumbosacral Plexopathies: Causing by Femoral Head Fracture

Abstract

Lumbosacral plexopathies is considerably less epidemiologic prevalence. This is due to the relatively protected position of these neural structures. The causes are various such as tumors, hematomas, surgical damage, trauma, diabetes mellitus and paraneoplastic syndrome. The symptoms which are caused by compressing lumbosacral plexus are sensory disturbance and weakness in an affected leg. The author reports a case of 17-year-old male with history of right femoral head fracture status post open reduction and internal fixation by plate and screw who complained right foot drop and numbness along the leg. His first diagnosis was right sciatic neuropathy. However, 3 months later, he still had difficulty in walking and felt hyperesthesia over lateral aspect of the right leg and the dorsum of foot. His further investigation which was electrodiagnostic study was diagnosed right lumbosacral plexopathies. Although the most common neuropathy after femoral fracture is sciatic neuropathy, lumbosacral plexopathies should be considered.
