Trigger wrist due to idiopathic synovial hypertrophy

|October 1, 1986
Summary
Trigger wrist, a condition causing painful wrist catching, is often linked to carpal tunnel syndrome. This case highlights a unique instance in a healthy individual without carpal tunnel syndrome, caused by idiopathic synovial hypertrophy.
Area of Science:
- Orthopedics
- Hand Surgery
- Rheumatology
Background:
- Trigger wrist, first described in 1961, typically involves triggering at the wrist associated with carpal tunnel compression.
- Previous reports predominantly link trigger wrist to carpal tunnel syndrome.
Observation:
- A previously undescribed case of trigger wrist is presented.
- The patient is a fit young girl.
- The condition occurred without evidence of carpal tunnel syndrome.
Findings:
- The trigger wrist in this case was attributed to idiopathic synovial hypertrophy.
- This represents a novel etiology for trigger wrist in the absence of carpal tunnel syndrome.
Implications:
- This case expands the known differential diagnosis for trigger wrist.
- It suggests that idiopathic synovial hypertrophy should be considered in cases of trigger wrist, even without carpal tunnel syndrome.
- Further research may be warranted to understand the pathogenesis of idiopathic synovial hypertrophy in trigger wrist.
