Complications of Wrist Arthroscopy

PurposeThe purpose of this systematic review was to address the incidence of complications associated with wrist arthroscopy. Given the paucity of information published on this topic, an all-inclusive review of published wrist arthroscopy complications was sought.MethodsTwo independent reviewers performed a literature search using PubMed, Google Scholar, EBSCO, and Academic Megasearch using the terms “wrist arthroscopy complications,” “complications of wrist arthroscopy,” “wrist arthroscopy injury,” and “wrist arthroscopy.” Inclusion criteria were (1) Levels I to V evidence, (2) “complication” defined as an adverse outcome directly related to the operative procedure, and (3) explicit description of operative complications in the study.ResultsEleven multiple-patient studies addressing complications of wrist arthroscopy from 1994 to 2010 were identified, with 42 complications reported from 895 wrist arthroscopy procedures, a 4.7% complication rate. Four case reports were also found, identifying injury to the dorsal sensory branch of the ulnar nerve, injury to the posterior interosseous nerve, and extensor tendon sheath fistula formation.ConclusionsThis systematic review suggests that the previously documented rate of wrist arthroscopy complications may be underestimating the true incidence. The report of various complications provides insight to surgeons for improving future surgical techniques.Level of EvidenceLevel IV, systematic review of Levels I-V studies.
