Compression neuritis of the ulnar nerve treated with simple decompression

|January 1, 1977
Summary
Surgical decompression of the ulnar nerve at the flexor carpi ulnaris aponeurosis relieved symptoms in most patients with ulnar neuritis. This study validated Osborne's hypothesis regarding nerve compression location.
Area of Science:
- Orthopedic Surgery
- Neurology
Background:
- Ulnar neuritis symptoms are often attributed to nerve compression.
- Osborne's 1957 hypothesis suggested compression at the flexor carpi ulnaris aponeurosis.
Purpose of the Study:
- To test Osborne's hypothesis regarding the cause of ulnar neuritis.
- To evaluate the efficacy of surgical decompression for ulnar nerve compression.
Main Methods:
- Thirty-two simple decompression surgeries were performed on 31 patients diagnosed with ulnar nerve compression.
- Patients were followed for 5 years post-operation.
Main Results:
- 28 out of 31 patients (90%) experienced symptom relief.
- Four patients showed no improvement; three were misdiagnosed.
- Two patients required a second surgery; no complications were reported.
Conclusions:
- Surgical decompression at the flexor carpi ulnaris aponeurosis is effective for treating ulnar neuritis.
- The findings support Osborne's hypothesis on the primary site of ulnar nerve compression.
