This prospective study evaluates the outcomes of combined ECRB and APL tendon transfer for restoring pinch function in patients with chronic ulnar nerve injury. Patients will be followed postoperatively to assess improvement in hand function, strength, and daily activity performance. Participation is voluntary and all standard care procedures will be maintained
The study is a prospective, single-center interventional trial including adult patients diagnosed with chronic ulnar nerve injury affecting pinch function. Eligible participants will undergo combined ECRB (Extensor Carpi Radialis Brevis) tendon transfer to adductor pollicis tendon and APL (Abductor Pollicis Longus) tendon transfer to 1st dorsal interosseous tendon that performed by experienced surgeons. Preoperative evaluation includes baseline hand function, pinch strength, and disability assessment. Postoperative follow-up will occur at 4, 6, 12, and 24 weeks to measure functional improvement using standardized hand assessment tools. Adverse events will be monitored and recorded. Inclusion criteria: adults ≥18 years, chronic ulnar nerve injury >6 months, and consent to participate. Exclusion criteria: prior tendon transfer, coexisting neuromuscular disorder, or inability to provide consent. Data will be anonymized to maintain confidentiality, and all ethical approvals will be in place.

| Combined ECRB and APL Tendon Transfer | Procedure | This surgical procedure involves transferring the Extensor Carpi Radialis Brevis (ECRB) and Abductor Pollicis Longus (APL) tendons to restore pinch function in patients with chronic ulnar nerve injury. Standard postoperative physiotherapy will follow, with assessments at 4, 6, and 12 weeks to monitor pinch strength, thumb mobility, and any complications |
| Measure | Description | Time Frame |
|---|---|---|
| Mean Grip Strength of the Operated Hand Measured Using a Hand Dynamometer (kg) | Grip strength of the operated hand will be assessed using a calibrated hand dynamometer. Three consecutive measurements will be obtained during the same session, and the average value will be calculated and reported in kilograms. | 6 months postoperatively |
| Measure | Description | Time Frame |
|---|---|---|
| DASH Score (Disabilities of the Arm, Shoulder and Hand Questionnaire) | Functional outcome will be assessed using the DASH questionnaire. The total score ranges from 0 to 100, with higher scores indicating greater disability. The overall total score will be reported. | 3 months postoperatively |

Participants will be assigned to intervention or control arms to evaluate functional improvement after ECRB and APL tendon transfer. Each participant will undergo baseline assessment of hand function, and post-operative follow-ups will assess pinch restoration, grip strength, and dexterity

The outcomes assessor performing post-operative functional evaluations will be blinded to the intervention assignment to minimize assessment bias.
