Trauma of the hand from a circular saw table is a common occurrence in developing countries it tends to occur in young hand working people and it causes a serious lesions.
It was a retrospective series about a 130 cases of hand trauma from circular saw table. Epidemiological features, treatment, and permanent disabilities left by hand trauma from circular saw table were studied to identify ways to prevent such an accident.
The average age was 31.24 years, these patients were exclusively men, 62% were apprentice wood workers, and the left hand was twice more injured than the right hand. Regarding clinical aspects, in 77% of cases, two or more fingers were injured, tip amputations of the left fingers predominated (49%), in 50% of the cases of hand wounds occurred to the dorsum of the hand, and extensor tendon injuries were observed twice more than flexor tendon injuries. Regarding the surgical treatment, performing an amputation stump was the most practiced primary surgery (107 cases i.e. 82% of primary surgeries). Arthrodesis, reconstructive flap surgery, and spongy bone grafts were the most practiced secondary surgeries (79% of secondary surgeries). Joint stiffness was the most observed complication (26%).
Hand injuries from circular saw table such as those described in this study will continue to challenge the skill of surgeons devoted to the restoration of function and form to the damaged hand. Prevention, of course, should be the goal because of the severe functional and psychological impairment that may result from them.
在发展中国家，圆锯台导致的手部创伤很常见，这类创伤往往发生在从事手工劳动的年轻人身上，会造成严重损伤。
这是一项关于130例圆锯台所致手部创伤的回顾性研究。研究了圆锯台所致手部创伤的流行病学特征、治疗方法以及造成的永久性残疾，以确定预防此类事故的方法。
患者平均年龄为31.24岁，均为男性，62%为木工学徒，左手受伤次数是右手的两倍。临床方面，77%的病例中有两根或更多手指受伤，左手手指末节离断占主导（49%），50%的手部伤口出现在手背，伸肌腱损伤的发生率是屈肌腱损伤的两倍。手术治疗方面，截肢残端手术是最常用的一期手术（107例，即一期手术的82%）。关节固定术、重建皮瓣手术和松质骨移植是最常用的二期手术（二期手术的79%）。关节僵硬是最常见的并发症（26%）。
本研究中描述的圆锯台所致手部损伤将继续考验致力于恢复受损手部功能和外形的外科医生的技术。当然，由于此类损伤可能导致严重的功能和心理障碍，预防应是目标。
