Camptodactyly caused by an abnormal lumbrical muscle
Journal of Hand Surgery (Edinburgh, Scotland)
|February 1, 1985
Summary
An abnormal lumbrical muscle insertion caused hand pain in a young patient. Surgical correction by detaching and repositioning the lumbrical muscle tendon relieved the symptoms.
Area of Science:
- Hand surgery
- Orthopedic surgery
- Anatomy
Background:
- Abnormal lumbrical muscle insertion can cause pain and functional deficits in the hand.
- Understanding the anatomical variations of lumbrical muscles is crucial for diagnosing and treating hand conditions.
Observation:
- A 13-year-old female presented with right little finger pain and extension difficulty.
- Imaging revealed an anomalous insertion of the lumbrical muscle into the flexor digitorum superficialis tendon.
Findings:
- Surgical intervention involved detaching the aberrant lumbrical muscle.
- The lumbrical muscle tendon was successfully transferred to the lateral band, restoring normal function.
Implications:
- This case highlights the importance of recognizing lumbrical muscle anomalies in pediatric hand pain.
- Tendon transfer surgery is an effective treatment for symptomatic lumbrical muscle abnormalities.
- Accurate anatomical knowledge aids in successful surgical outcomes for complex hand conditions.
