Summary
Ganglions near the pisotriquetral joint can cause ulnar wrist pain. This soft-tissue mass, originating from the joint, should be considered in diagnoses for wrist pain without trauma.
Area of Science:
- Orthopedics
- Hand Surgery
- Radiology
Background:
- Ulnar wrist pain is a common complaint.
- Ganglion cysts are benign soft-tissue masses.
- The pisotriquetral joint is a potential source of wrist pain.
Observation:
- A patient presented with painful swelling on the ulnar side of the dominant right wrist.
- Physical examination revealed a mobile soft-tissue mass.
- Radiographs showed no abnormalities.
Findings:
- Surgical exploration identified a 1 cm x 1 cm ganglion cyst.
- The cyst had a stalk originating from the ulnar aspect of the pisotriquetral joint.
- The ganglion was located adjacent to the hypothenar muscles.
Implications:
- Ganglions arising from the pisotriquetral joint should be considered in the differential diagnosis of ulnar wrist pain.
- This finding may improve diagnostic accuracy for ulnar wrist pain.
- Further research may elucidate the exact mechanism of ganglion formation at this joint.
