|September 17, 2015
Summary
The modified Murray technique effectively treats carpal navicular nonunion, achieving a 93.1% healing rate with a low incidence of wrist osteoarthritis. Early intervention minimizes degenerative joint disease risks.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Traumatology
Background:
- Carpal navicular nonunion is a challenging condition often leading to osteoarthritis.
- Previous treatments have variable success rates and complication profiles.
Purpose of the Study:
- To evaluate the long-term outcomes of a modified Murray technique for carpal navicular nonunion.
- To assess union rates, functional outcomes, and the incidence of osteoarthritis post-surgery.
Main Methods:
- A retrospective review of 29 patients treated with a modified Murray technique and bone grafting.
- Long-term follow-up (mean 11.2 years) assessing radiographic union, pain, range of motion, and wrist function (DASH score).
Main Results:
- A high union rate of 93.1% was achieved.
- Most patients were asymptomatic or had occasional pain, with a low incidence of mild osteoarthritis (SNAC stage I).
- Avascular necrosis of the proximal fragment did not preclude successful union.
Conclusions:
- The modified Murray technique offers a reliable and effective treatment for carpal navicular nonunion.
- Early diagnosis and treatment are crucial to prevent advanced degenerative changes.
- The technique demonstrates a favorable union rate and low complication profile compared to other methods.
