Sohag University17 enrolled

Overview

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.

Interventions

Combined ECRB and APL Tendon TransferPROCEDURE

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

Inclusion Criteria: * Patients with chronic ulnar nerve injury (more than 1 year duration). * Age between 18 and 60 years. * Patients with stable joints and good passive range of motion of the hand and fingers. * Absence of active infection or severe contracture. Exclusion Criteria: * • Patients with combined median or radial nerve injury. * Patients with severe soft-tissue loss or fixed deformities precluding tendon transfer. * Uncooperative patients or those with systemic diseases affecting muscle power or healing (e.g., diabetes mellitus, peripheral vascular disease).

Outcomes

Primary Outcomes

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.

Time frame: 6 months postoperatively

Secondary Outcomes

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.

Time frame: 3 months postoperatively
