Summary
For partial flexor tendon lacerations, a simple running suture repair resulted in less gliding resistance compared to Halsted or Silfverskiold repairs. This technique is recommended for surgical repair of these injuries.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
- Hand Surgery
Background:
- Partial flexor tendon lacerations require surgical intervention when deeper than 70%.
- Evaluating the biomechanical impact of different repair techniques on tendon gliding is crucial for optimal functional recovery.
- Existing repair methods may introduce varying degrees of friction, potentially affecting outcomes.
Purpose of the Study:
- To compare the gliding resistance of three distinct peripheral repair techniques for partial flexor tendon lacerations.
- To determine which repair method minimizes friction and facilitates smoother tendon movement post-surgery.
Main Methods:
- Thirty turkey toe flexor tendons with A2 pulleys were utilized.
- Gliding resistance was measured in intact tendons, then after 50% laceration and repair using modified Kessler core suture with either Halsted, Silfverskiold, or simple running suture techniques.
Main Results:
- The Halsted repair increased gliding resistance by 100%, Silfverskiold by 80%, and simple running suture by 60% compared to intact tendons (p=0.05).
- The simple running suture technique demonstrated the lowest increase in gliding resistance among the tested methods.
Conclusions:
- A simple running suture technique is superior in minimizing gliding resistance after partial flexor tendon repair.
- This technique is recommended for clinical application in surgical repair of partial flexor tendon lacerations to improve tendon gliding and function.
