This study presents a novel surgical technique for extensor tendon subluxation at the metacarpophalangeal joint. The described sagittal band reconstruction effectively eliminated pain and prevented recurrence in all patients.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Reconstructive Surgery

Background:

  • Extensor tendon subluxation at the metacarpophalangeal joint is a rare condition, particularly in patients without rheumatoid arthritis.
  • Most cases involve radial sagittal band disruption leading to ulnar extensor tendon subluxation.
  • Existing treatments may not fully address the underlying sagittal band instability.

Purpose of the Study:

  • To describe a new technique for sagittal band reconstruction.
  • To evaluate the efficacy of this technique in treating extensor tendon subluxation.
  • To assess outcomes regarding pain relief and recurrence rates.

Main Methods:

  • A novel sagittal band reconstruction technique was developed, involving weaving a retrograde extensor tendon segment.

Related Experiment Videos

  • The tendon segment was passed through the deep transverse metacarpal ligament.
  • Twenty-one reconstructions were performed on 16 patients with various extensor tendon subluxation patterns.

    • Main Results:

    • The series included 18 cases of ulnar subluxation (radial band disruption) and 3 cases of radial subluxation (ulnar band disruption).
    • Pain was completely eliminated in all 21 reconstructed cases.
    • No instances of extensor tendon subluxation recurrence were observed post-operatively.

    Conclusions:

    • The described retrograde extensor tendon weaving technique is a highly effective method for sagittal band reconstruction.
    • This surgical approach provides durable resolution of extensor tendon subluxation and associated pain.
    • The technique offers a reliable solution for both ulnar and radial extensor tendon subluxation at the metacarpophalangeal joint.
