Wrist Arthroscopy Is Effective for the Diagnosis and Treatment of Chronic Wrist Pain in Pediatric Patients.

PURPOSE

To determine the outcomes of diagnostic and therapeutic arthroscopy in patients with chronic wrist pain who are younger than 16 years of age.

METHODS

We retrospectively analyzed collected data from medical records of patients who had undergone wrist arthroscopy by the senior author between 2015 and 2017 for longstanding wrist pain and were 16 years old or younger. Findings from preoperative magnetic resonance imaging (MRI) were compared with the intraoperative diagnosis, and midterm results were gathered by a telephone interview.

RESULTS

Ten patients were included. Eight of 10 patients had undergone conservative therapy before surgery, and 60% had a history of single trauma. In 6 of 10 patients, the arthroscopic diagnosis correlated with the MRI findings. Eight of 10 wrists (80%) showed a tear of the triangular fibrocartilage complex (TFCC). Only 4 of the 8 TFCC tears were correctly identified by 3-Tesla MRI.

CONCLUSIONS

In our study, wrist arthroscopy was an effective tool not only to diagnose but also to treat relevant TFCC lesions both in adolescents and children suffering from persistent wrist pain. A 3-Tesla MRI was neither sensitive nor specific enough to correctly diagnose lesions in small pediatric wrists.
