Flexor pollicis longus tendon repair: a comparison between dynamic and static splintage

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Reconstructive Surgery

Background:

• Isolated flexor pollicis longus (FPL) tendon injuries require effective post-operative management.
• The optimal splinting strategy following FPL tendon repair remains a subject of clinical debate.
• Assessing functional outcomes is crucial for guiding treatment protocols.

Purpose of the Study:

• To evaluate the efficacy of post-operative splinting methods in isolated flexor pollicis longus tendon repairs.
• To compare outcomes between dynamic traction and static immobilization.
• To determine if specific tendon zones benefit more from certain splinting techniques.

Main Methods:

• Retrospective review of 51 patients undergoing isolated FPL tendon repair.
• Classification of outcomes using the Buck-Gramcko criteria.
• Comparison of results between patients treated with dynamic traction versus static splinting.

Main Results:

• Overall, 60% of patients treated with dynamic traction achieved good or excellent results, compared to 44% with immobilization.
• For zone 2 FPL tendon repairs, dynamic mobilization resulted in good or excellent outcomes in 62% of cases, versus 33% with fixed splintage.
• Controlled dynamic mobilization demonstrated superior functional recovery compared to immobilization.

Conclusions:

• Dynamic traction is a more effective post-operative management strategy for isolated flexor pollicis longus tendon repairs.
• Zone 2 FPL tendon repairs show a significant benefit from dynamic mobilization over fixed splinting.
• Implementing controlled dynamic mobilization can optimize patient recovery and functional outcomes in FPL tendon surgery.
