title: Interfascicular Neurolysis for Incomplete Spontaneous Posterior Interosseous Nerve Palsy with a Surgical Delay of 17 Years: Is It Still Effective?
abstract: A 55-year-old woman with incomplete spontaneous posterior interosseous nerve (PIN) palsy underwent interfascicular neurolysis and tendon transfer, 17 years after its onset. After one year, her nerve function partially recovered electrophysiologically. This case suggests that incomplete spontaneous PIN palsy may recover by interfascicular neurolysis, even with a long preoperative delay.
