Fracture both bones forearm is one of the commonly encountered fracture in orthopaedics, for which open reduction and internal fixation is needed to get anatomical reduction. For proximal third and middle third junction fractures of radius, dorsal plating using Thompson’s approach is in vogue. However, it is associated with injury of Posterior Interosseous Nerve (PIN) leading to the weakness of extension of Metacarpo Phalangeal (MCP) joints of fingers and Interphalangeal joint (IP joint) of thumb. Usually, all the fingers are equally affected. But in this the case report, a rare presentation of weakness of extension of MCP joint of index finger alone in a 28-year-old male patient following open reduction internal fixation using Thompson’s approach is observed.
