Summary

Advanced Kienböck's disease can cause spontaneous extensor tendon ruptures due to lunate bone fragments. Surgical treatment involving lunate excision and tendon reconstruction effectively restored hand function.

Area of Science:

  • Orthopedics
  • Hand Surgery
  • Musculoskeletal Disorders

Background:

  • Kienböck's disease is a condition affecting the lunate bone in the wrist.
  • Advanced stages can lead to significant carpal pathology and complications.

Observation:

  • A patient presented with spontaneous, multiple extensor tendon ruptures.
  • A displaced fragment of the lunate bone was identified as the cause.

Findings:

  • The patient had advanced Kienböck's disease with lunate instability.
  • Surgical intervention included complete lunate excision, limited carpal fusion, and extensor tendon reconstruction.

Implications:

  • This case highlights a rare complication of advanced Kienböck's disease.
