A novel three-loop technique for secondary A2 pulley reconstruction significantly improved finger joint motion and reduced fingertip-to-palm distance. All patients regained satisfactory grip function following the procedure.

Area of Science:

Hand surgery
Orthopedic surgery
Reconstructive surgery

Background:

Secondary A2 pulley reconstruction is crucial for restoring finger function after injury or previous surgery.
Limited effective surgical techniques exist for addressing A2 pulley defects, impacting patient outcomes.
The A2 pulley is vital for maintaining flexor tendon function during gripping.

Observation:

A novel three-loop surgical technique was developed for secondary A2 pulley reconstruction.
The technique was successfully applied to six patients with A2 pulley deficiencies.
A mean follow-up of 21 months (range: 9 months to 3 years) was recorded.

Findings:

Significant improvement in total active motion across metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints (average increase of 30 degrees).

Average reduction in tip-to-palm distance by 10 mm, indicating improved flexion and hand function.

All six patients achieved satisfactory grip strength and function post-reconstruction.

Implications:

This three-loop technique offers a promising solution for secondary A2 pulley reconstruction.
The procedure demonstrates potential for restoring significant finger mobility and grip strength.
Further studies could validate this technique in larger patient cohorts for broader clinical application.
