Comparison of cases with and without carpal tunnel release in volar plate fixation of AO type 23-B and 23-C fractures

Abstract

Aim: To compare the functional results and the frequency of carpal tunnel syndrome between patients who underwent Open reduction internal fixation(ORIF)+carpal tunnel release(CTR) and those who underwent isolated open reduction internal fixation in AO 23 B and C type fractures.

Methods: Patients with AO Type 23-B1, 23-B2, 23-B3, 23-C1, 23-C2, and 23-C3 fractures who underwent ORIF were included in the study. The patients who underwent ORIF were divided into two groups: those who underwent CTR and those who did not. The patients’ VAS scores and Patient-Rated Wrist Evaluation (PRWE) scores were evaluated on postoperative day 1,  month one,  month three,  month six, and month twelve.

Results: Eighty-two patients were included in the study. ORIF+CTR was performed in 46 patients, and isolated ORIF was performed in 36 patients. CTS symptoms were observed in 6 patients in the group that only underwent ORIF at postoperative three months. At the 6-month control EMG, CTS was detected in 5 out of 6 patients where only ORIF was performed.

Conclusion: Concomitant CTR during ORIF in AO type 23B and 23C fractures is an effective surgical treatment procedure in preventing the development of CTS.
