Posterior interosseous nerve palsy caused by parosteal lipoma of proximal radius

An 83-year-old woman presented with weakness in her right-hand and wrist extensors and swelling in the proximal part of the right forearm. Electromyography (EMG) confirmed involvement of posterior interosseous nerve at the level of proximal forearm. MR imaging demonstrated the characteristics of lipoma which extended on the anterolateral aspect of the right forearm and at the level of the radius neck. The lesion was parosteal lipoma causing compression and paralysis of the posterior interosseous nerve without sensory deficit. In this paper, posterior interosseous nerve palsy due to compression of a parosteal lipoma recovered after excision of the lipoma followed by intensive rehabilitation for six month. Surgical excision should be performed to ensure optimal recovery from the nerve paralysis.

Posterior Interosseous Nerve Palsy

Lipomas are extremely common benign soft tissue tumours that are usually subcutaneous and asymptomatic. Occasionally, lipomas can occur in deeper soft tissue planes and when adjacent to the neck of the radius they can cause compression of the posterior interosseous nerve. Five such cases are described. An anterior approach to excision of the lipoma is recommended.

Standard Posterior Approach

The Thompson’s approach is used as the standard posterior approach by many surgeons. Although posterior interosseous nerve palsy following the Thompson’s approach has been reported by several authors, isolated paralysis of the extensor digitorum communis (EDC) is a rare occurrence. We report to you a case of isolated paralysis of EDC following the Thompson’s approach in a 14-year-old boy who recovered completely on the 5th postoperative day. Each of the approaches to the proximal radius poses a risk of damage to the posterior interosseous nerve and its branches because of traction. Damage may occur during exposure or implant insertion. Any surgery around the supinator and the radial tunnel region is dangerous because of complex anatomy, lack of intermuscular planes and varying distribution of the radial nerve. Avoiding excessive posterior or ulnar retraction of the EDC and improper dissection can avoid the “sign of horns” deformity following the Thompson’s approach.
