Summary

The double loop locking suture (DOLLS) technique offers strong flexor tendon repair, enabling early active mobilization. This method showed promising results in four patients, supporting its effectiveness in postoperative tendon management.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Biomedical Engineering

Background:

  • Traditional suture methods for flexor tendons pose limitations on postoperative management.
  • The double loop locking suture (DOLLS) technique has emerged as a potentially stronger alternative for flexor tendon repair.

Observation:

  • This study reports on four cases utilizing the DOLLS technique for flexor digitorum profundus (FDP) tendon repair.
  • Early active mobilization was commenced between postoperative days 3 and 7.
  • Results were evaluated using Strickland's formula, with two excellent, one good, and one fair outcome.

Findings:

  • The DOLLS technique demonstrated sufficient in vitro strength (average 4,400 g) to allow early active mobilization.
  • While a flexor digitorum superficialis (FDS) tendon repaired with a modified Kessler technique ruptured, the DOLLS-repaired FDP tendon remained intact.

Related Experiment Videos

  • The DOLLS technique facilitated successful early active mobilization in the majority of cases.

    • Implications:

    • The DOLLS technique appears to be an effective surgical option for flexor tendon repair, allowing for earlier patient mobilization.
    • This technique may improve functional outcomes and reduce complications associated with delayed mobilization after flexor tendon injuries.
    • Further research with larger cohorts is warranted to validate these findings and establish optimal postoperative protocols.
