Preserving these nerves is important to prevent complications such as neuroma formation and motor and sensory changes to the hand. We conducted a review of the literature to assess the nerves at risk and whether \u2018safe zones\u2019 exist to avoid these nerves. An independent reviewer conducted searches in Embase and MEDLINE of the literature from 2010 to 2020. A total of 68 papers were identified, with 18 articles being included in the review. Multiple nerves were identified as being at risk for each of the approaches described. In the anterior approach, the palmar cutaneous branch of the median nerve (PCBMN) is most at risk of injury. An incision immediately radial to the flexor carpi radialis (FCR) or directly over the FCR is most likely to avoid injury to both superficial branch of the radial nerve (SBRN) and PCBMN. With Thompson's approach, the safest zone for an incision is directly over or slightly radial to Lister's tubercle to avoid injury to SBRN and lateral cutaneous nerve of the forearm. For the ulnar approach, a safe zone was shown to be on the ulnar side of the wrist around the ulnar styloid (US) when the forearm was in supination or a neutral position to avoid injury to the dorsal branch of the ulna nerve (DBUN). Care must be taken around the US due to the density of nerves and the proximity of the last motor branch of the posterior interosseous nerve to the ulnar head. This review highlighted the proximity of nerves to the three most common surgical incisions used to access the forearm. In addition, anatomical variations may exist, and each of the nerves identified as being at risk has multiple branches. Both factors increase the potential of intraoperative damage if the anatomy is not properly understood. The surgeon must adhere carefully to the established approaches to the wrist and distal forearm to minimize damage to nerves and optimize surgical outcomes for the patient.<\/jats:p>","DOI":"10.1002\/ca.24129","type":"journal-article","created":{"date-parts":[[2023,12,8]],"date-time":"2023-12-08T01:44:53Z","timestamp":1701999893000},"page":"425-439","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Systematic review of nerves at risk at the wrist in common surgical approaches to the forearm: Anatomical variations and surgical implications"],"prefix":"10.1002","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-2977-6203","authenticated-orcid":false,"given":"Hannah","family":"Bridgwater","sequence":"first","affiliation":[{"name":"Department of Trauma and Orthopaedics East and North Hertfordshire NHS Trust, Lister Hospital  Stevenage UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamara","family":"Mertz","sequence":"additional","affiliation":[{"name":"Burns and Plastic Surgery Department North Bristol NHS Trust  Bristol UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cecilia","family":"Brassett","sequence":"additional","affiliation":[{"name":"Human Anatomy Centre, Anatomy Building, Department of Physiology, Development and Neuroscience University of Cambridge  Cambridge UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neil","family":"Ashwood","sequence":"additional","affiliation":[{"name":"Research Institute Wolverhampton University  Wulfruna St Wolverhampton UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,12,7]]},"reference":[{"issue":"1","key":"e_1_2_9_2_1","first-page":"190","article-title":"Variation in the site of emergence of the median nerve in the human forearm and its clinical significance (conference abstract)","volume":"236","author":"Bostock S.","year":"2020","journal-title":"Journal of Anatomy"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0363-5023(09)90022-3"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rboe.2018.07.010"},{"key":"e_1_2_9_5_1","volume-title":"Surgical anatomy of the hand and upper extremity","author":"Doyle J.
