Pain Management of Sciatic Nerve Injury Induced by Intramuscular Injection Using Distal Nerve Block

Injury to the sciatic nerve from dorsogluteal intramuscular (IM) injection is not an uncommon iatrogenic cause. This case report discusses the successful management of a child with sciatic nerve injury due to an IM injection in the left gluteal region. The child experienced severe pain that was not responding to pharmacological therapy and was limiting physiotherapy, which forms an important step in the management of patients with peripheral nerve injuries. The case report outlines the use of a posterior tibial nerve block, which provided immediate relief of pain sensations in the sole of the foot, allowing the child to walk and eventually improving sleep and appetite. The report suggests that distal nerve blocks may be an effective treatment option for patients with severe neuropathic symptoms resulting from peripheral nerve injury.
