Summary
A rare bilateral flexor pollicis longus tendon anomaly was found, with unusual insertions into both proximal and distal phalanges. This case highlights a previously unreported congenital abnormality of the flexor pollicis longus tendon.
Area of Science:
- Anatomy
- Congenital Abnormalities
- Hand Surgery
Background:
- The flexor pollicis longus (FPL) is a key muscle in thumb flexion.
- Congenital anomalies of the FPL tendon are uncommon.
- Accurate diagnosis is crucial for appropriate management.
Observation:
- A case presented with suspected congenital absence of the FPL tendon.
- Intraoperative findings revealed an intact FPL tendon.
- The anomaly involved bilateral, unusual insertions into both proximal and distal phalanges.
Findings:
- This represents a unique case of bilateral FPL tendon insertion abnormality.
- Literature review found no similar reported cases of FPL tendon insertion anomalies.
- The condition was initially misdiagnosed due to its rarity.
Implications:
- This finding expands the spectrum of known congenital FPL abnormalities.
- Highlights the importance of surgical exploration for definitive diagnosis.
- May inform future understanding and classification of hand tendon anomalies.
