Diagnosis and treatment of obscure ulnar-sided wrist pain

Thirty-seven patients were followed for symptoms of chronic ulnar-sided wrist pain in which specific physical examination and standard radiographs were unrevealing. Initial conservative treatment did not relieve the pain. The patients underwent further diagnostic studies including dynamic cineroentgenographic evaluation and radiocarpal arthrography. Nineteen of the 37 patients were demonstrated to have a triangular fibrocartilage complex (TFCC) tear on arthrography; 18 had a normal examination. The average follow up was 23 months. Seven of the 19 patients with TFCC tears have undergone operative treatment, and 5 (71%) remain symptomatic. Of the remaining 12 patients with TFCC tears treated nonoperatively, eight (67%) have persistent symptoms. Of the 18 patients whose arthrograms were normal, five eventually underwent surgical exploration, four of which remain symptomatic. Of the 13 patients without TFCC tears treated nonoperatively, seven (54%) continue to have symptoms. In our experience, both surgical exploration and nonoperative treatment have been less than satisfying. In addition, treatment results could not be correlated with arthrographic findings.
