We report about a 29-year-old man presenting with traumatic tissue loss at the distal interphalangeal (DIP) joint of the index finger, including skin, bone, and nerve. Reconstruction using two types of flaps was performed. The dorsal skin flap, nourished by the second dorsal metacarpal artery (SDMA) perforator, was elevated. The vascularized second metacarpal bone, nourished by the SDMA, was also elevated. Using the vascular connection between the DMA and the palmar digital artery (PDA), both flaps were raised to the distal part of the finger, and the pivot point was set at the dorsal proximal phalanx. After arthrodesis of the DIP joint with the vascularized second metacarpal bone, the digital nerve was repaired using the cutaneous nerve in the skin flap, and the skin defect was covered using the perforator flap. The postoperative course, including flap survival and bone union, was uneventful.

A common etiological factor for this difficulty, among others, is lack of a low-cost and easy-to-assemble low fidelity suturing model. The purpose of this study is the demonstration of a validated, practical, inexpensive, hand-shaped anatomy training model. It is addressed to medical students and graduates that wish to get acquainted with neurovascular anatomy of the hand and improve their basic surgical skills. The model requires only two latex gloves, cotton, and two different color markers per trainee to draw the course of large nerve and vessels. Construction requires less than 15 minutes. For validation, 80 students participated as volunteers in the demonstration course. They evaluated course usefulness and their own confidence after the course. According to the 5-point Likert scale, the participants' confidence increased in a statistically significant way ( <i>p</i> < 0.05). All participants (100%) stated that their skills were \"significantly improved\" in terms of instrument handling, anatomy studying, performing digital anesthesia, and suturing technique. Overall experience was rated as \"satisfactory\" or above. The proposed model enables safe gentle soft-tissue handling, and it resembles a realistic human tissue. Low cost, availability, and fast construction are the most important characteristics, making this validated training model appropriate for acquiring fundamental local anesthesia, respect for hand neurovascular anatomy, and suturing skills.</p>","PeriodicalId":45368,"journal":{"name":"Journal of Hand and Microsurgery","volume":"13 3","pages":"185-188"},"PeriodicalIF":0.3,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8426050/pdf/10-1055-s-0040-1721567.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39408157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
