This project, designed as a retrospective cohort model, was conducted at three large, urban referral\u2010based diabetic foot clinics. The investigators abstracted medical records from 180 patients with diabetes, 76\u00b71% male, aged 57\u00b78 \u00b1 11\u00b72 years, falling equally into four classes of a previously reported diabetic foot surgery classification system. These classes included class 1 (elective), class 2 (prophylactic), class 3 (curative) and class 4 (emergency). There was a significant trend towards increasing risk of ulceration\/reulceration (\u03c7<jats:sup>2<\/jats:sup><jats:sub>trend<\/jats:sub>= 17\u00b78,<jats:italic>P<\/jats:italic>= 0\u00b70001), peri\u2010postoperative infection (\u03c7<jats:sup>2<\/jats:sup><jats:sub>trend<\/jats:sub>= 96\u00b79,<jats:italic>P<\/jats:italic>= 0\u00b70001), all\u2010level amputation (\u03c7<jats:sup>2<\/jats:sup><jats:sub>trend<\/jats:sub>= 41\u00b77<jats:italic>P<\/jats:italic>= 0\u00b7001) and major amputation (\u03c7<jats:sup>2<\/jats:sup><jats:sub>trend<\/jats:sub>= 8\u00b76,<jats:italic>P<\/jats:italic>= 0\u00b7003), with increasing class of foot surgery. The results of this study suggest that a non vascular foot surgery classification system including variables such as the presence or absence of neuropathy, an open wound and acute infection may be predictive of peri\u2010 and postoperative complications. This may assist the surgeon in better identifying risk when determining a rationale for and type of surgery in persons with diabetes.<\/jats:p>","DOI":"10.1111\/j.1742-481x.2006.00236.x","type":"journal-article","created":{"date-parts":[[2006,9,19]],"date-time":"2006-09-19T15:05:55Z","timestamp":1158678355000},"page":"240-246","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":45,"title":["Validation of a diabetic foot surgery classification"],"prefix":"10.1111","volume":"3","author":[{"given":"David G","family":"Armstrong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lawrence A","family":"Lavery","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert G","family":"Frykberg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephanie C","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew JM","family":"Boulton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,9,19]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.293.2.217"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.7547\/87507315-83-2-101"},{"key":"e_1_2_5_4_2","first-page":"557","article-title":"Preventing loss of the great toe with the hallux interphalangeal arthroplasty","volume":"33","author":"Rosenblum BI","year":"1994","journal-title":"J Foot Ankle Surg"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1067-2516(96)80132-3"},{"key":"e_1_2_5_6_2","doi-asserted-by":"crossref","first-page":"433","DOI":"10.1177\/107110070202300511","article-title":"Forefoot narrowing with external fixation for problem cleft wounds","volume":"23","author":"Strauss MB","year":"2002","journal-title":"Foot Ankle Int"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110079902000203"},{"key":"e_1_2_5_8_2","first-page":"Oa20","article-title":"Orthopedic surgery treatment of diabetic neuropathic osteoarthropathy","volume":"135","author":"Wetz HH","year":"1997","journal-title":"Z Orthop Ihre Grenzgeb"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.2337\/diacare.17.9.983"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9610(94)90203-8"},{"key":"e_1_2_5_11_2","first-page":"29","article-title":"Panmetatarsal head resection and transmetatarsal amputation versus solitary partial ray resection in the neuropathic foot","volume":"30","author":"Cohen M","year":"1991","journal-title":"J Foot Surg"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1990.01410190024003"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.7547\/87507315-80-4-211"},{"key":"e_1_2_5_14_2","first-page":"66","article-title":"Spontaneous fractures of the lesser metatarsals secondary to an amputated hallux and peripheral neuropathy","volume":"26","author":"Iannucci AJ","year":"1987","journal-title":"J Foot Surg"},{"key":"e_1_2_5_15_2","doi-asserted-by":"publisher","DOI":"10.7547\/87507315-76-1-33"},{"key":"e_1_2_5_16_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110078200300305"},{"key":"e_1_2_5_17_2","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1976.01360270036006"},{"key":"e_1_2_5_18_2","doi-asserted-by":"publisher","DOI":"10.2337\/diacare.26.12.3284"},{"key":"e_1_2_5_19_2","doi-asserted-by":"publisher","DOI":"10.7547\/0950353"},{"key":"e_1_2_5_20_2","doi-asserted-by":"crossref","first-page":"1436","DOI":"10.2106\/00004623-200308000-00003","article-title":"Effect of achilles tendon lengthening on neuropathic plantar ulcers.
