Flexor Tendon Repair in Zone II Augmented With an Externalized Detensioning Suture: Protected Flexor Tendon Repair

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Reconstructive Surgery

Background:

• Flexor tendon repair in zone II is crucial for restoring hand function.
• Early finger motion is essential post-surgery to prevent joint stiffness.
• Standard repairs may be challenged by patient compliance or extensive soft-tissue damage.

Purpose of the Study:

• To present a novel technique augmenting zone II flexor tendon repair.
• To facilitate early active motion following flexor tendon repair.
• To provide a secure repair option for challenging surgical cases.

Main Methods:

• A zone II flexor tendon repair technique is described.
• An externalized detensioning suture is utilized to augment the primary repair.
• The technique is compatible with various standard flexor tendon repair methods.

Main Results:

• The externalized detensioning suture strengthens the flexor tendon repair.
• Early active motion is enabled, beneficial for patient compliance and recovery.
• A potential limitation is reduced distal interphalangeal joint motion until suture removal.

Conclusions:

• This technique offers a secure method for zone II flexor tendon repair.
• It supports early active mobilization, particularly in compliant patients or severe injuries.
• Careful consideration of potential distal joint motion limitations is advised.
