Sciatic nerve injury following intramuscular gluteal injection in childern: An electrophysiological study

Sciatic nerve injury is a common complication following intramuscular injection and the sciatic nerve is the most frequently affected nerve, especially in children. The neurological presentation may range from minor transient pain to severe sensory disturbance and motor loss with poor recovery. The aim of the study is to investigate the electrophysiological findings of sciatic nerve injury following intramuscular injection in children and to detect the prognosis of this injury. Twentyfive child patient with sciatic nerve injury caused by intramuscular injection are included in this study. They are diagnosed through short history; clinical examination andel ectrophysiological study in the Nineveh Handicap Rehabilitation center and private clinic. Nerve conduction study for sciatic nerves (common peroneal and posterior tibial nerves-motor) and sural nerves (sensory) bilaterally are done for the patients to study the Distal moto rand sensory latency (DML; DSL); Compound motor and sensory action potential (CMAP; SNAP); and Conduction nerve velocities (NCV); by using Neuropack EMG\EP measuring system-Nihoncodene (MEB-9400K) and EMG_NT Electromyography & Nerve Conduction Studies for Galileo NT Line (Nemus-2). The common peroneal nerve is most frequently affected than the tibial nerve. Sensory sural nerve injury is detected in our study in 3 patients. Child patients with BM(25-29.9kg\m2) show less sciatic nerve injury than who have BMI(18.5-24.9 kg\m2).
