Summary
Temporary scaphotrapezoidal (ST) joint fixation offers excellent clinical and radiographic outcomes for adolescent Kienböck
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Pediatric Orthopedics
Background:
- Adolescent Kienböck's disease lacks established therapeutic guidelines.
- Kienböck's disease affects the lunate bone in the wrist, causing pain and functional limitations.
Purpose of the Study:
- To evaluate the clinical and radiographic results of temporary scaphotrapezoidal (ST) joint fixation in adolescent patients with Kienböck's disease.
Main Methods:
- Retrospective review of 6 adolescent patients (mean age 14) with Kienböck's disease.
- Temporary ST joint fixation using K-wires inserted from the trapezoid to the scaphoid.
- Follow-up averaged 23 months, with K-wire removal at 3-6 months.
Main Results:
- Significant improvements in wrist extension (46° to 68°) and flexion (48° to 77°).
- Grip strength increased from 52% to 86% of the unaffected side.
- No postoperative pain; radiographic imaging showed no lunate sclerosis or fragmentation, with MRI indicating improved lunate intensity.
Conclusions:
- Temporary ST joint fixation demonstrated excellent clinical and radiographic outcomes in adolescent Kienböck's disease.
- The procedure is recommended for surgical treatment in this patient population.
