Clinical findings and nerve transfers of the patients with iatrogenic cervical spine surgery.
| Case | Age, y/Gender | Cause | Preoperative Loss of Function | Time From Injury to Surgery, mo | Surgery (Nerve Transfer) | Postoperative Muscle Force | Postoperative Follow-Up, mo |
| 1 | 40/M | Anterior discectomy | Shoulder abduction after 30° | 7 | LHT to ant AxN | M4 | 9 |
| 2 | 36/F | Posterior laminectomy | Elbow flexion | 9 | Double fascicular nerve transfer | M4 | 7 |
| 3 | 28/M | Posterior laminectomy | Elbow flexion | 9 | Double fascicular nerve transfer | M4 | 12 |
| 4 | 42/M | Posterior laminectomy | Shoulder abduction andelbow flexion | 12 | Spinal accessory nerve to suprascapular nerve LHT to anterior AxN Double fascicular nerve transfer | M4 | 12 |
Note: Double fascicular nerve transfer, an ulnar nerve fascicle to the biceps motor branch and a fascicle of median nerve to brachialis motor branch of musculocutaneous nerve.
Ant AxN, anterior branch of axillary nerve; LHT, long head of triceps branch of radial nerve.
