No Benefits of Combining Proximal Row Carpectomy With PIN Neurectomy for Wrist Disorders-A Comparative Study With Systematic Review of the Literature.

Background: Posterior interosseous nerve (PIN) resection in combination with proximal row carpectomy (PRC), is a preferred method in order to obtain rapid recovery. However, the contribution of such combination to results isn't known well.

Objectives: We performed a comparative study to evaluate the effects of PIN neurectomy for PRC and a systematic review of the literature was performed to identify whether such combination has an advantage.

Methods: Patients with wrist diseases who underwent PRC were evaluated retrospectively. Patients without PIN neurectomy (group 1, n = 7) and with PIN neurectomy (group 2, n = 8) were compared in respect of mean age, follow-up, gender, Q-DASH, VAS, MAYO wrist scores, flexion-extension/radial-ulnar deviation range of motion at final follow-up. The MEDLINE database was searched for studies published between 2005 and 2015, as the second part of the study. The following keywords were used: "proximal," "row," "carpectomy." Studies, which met the inclusion criteria, were evaluated in terms of such combination.

Results: There were no significant difference between the groups in regard with age ( = .463), follow-up period ( = .728), the ranges of flexion-extension ( = .431) and radio-ulnar deviation ( = .689), Q-DASH ( = .452), and MAYO scores ( = .728). In the second part of the study, 12 studies met the inclusion criteria and none of them was specifically evaluating such combination. Only one study had specific comments on PRC with PIN neurectomy.

Conclusion: According to our study (which, to our knowledge, was the first comparative study in the literature), we advocate not to combine PRC with PIN neurectomy for such an approach has no advantage.
