Lateral intermuscular septum causing radial nerve compressio
Multiple sites of compression of the radial nerve have been described, some more commonly than others.

In this case, published in the Journal of Surgery Case Reports, the authors describe a case of radial nerve compression at the lateral intermuscular septum in a patient with a history of open reduction and internal fixation of a mid-shaft humerus fracture 10 years prior.

To thier knowledge, only one previous case of chronic radial nerve compression by the lateral intermuscular septum associated with a humeral shaft fracture has been described.

This patient’s clinical presentation with specific electrodiagnostic abnormalities, operative findings and post-operative symptom relief point towards the rare diagnosis of compression of the radial nerve at the level of the lateral intermuscular septum as the cause of his symptoms.
