Abstract

Nitinol is a shape-memory alloy that has many diverse applications in the field of orthopedics. There have been no previous investigations reporting clinical or radiographic outcomes of the use of nitinol staples in the definitive stabilization of the pubic symphysis. A retrospective chart review was completed on 42 patients who underwent operative stabilization of pubic symphyseal disruption at an urban level-1 trauma center. Patients treated with pelvic staples alone, or in conjunction with traditional plates and screws, were compared with those treated without the use of a shape memory alloys. Thirty-four patients were included for final analysis (8 staples and 26 controls) in this investigation. Three of eight patients in the pelvic staple group had implant failures, with two having a loss of reduction (25%); this was not significantly different from the seven hardware failures (P = 0.61) seen in the control group without any loss of reduction (P = 0.17). Failures in the nitinol staple group occurred earlier at 17.3 days compared with the control group at 101.7 days (P = 0.003). There were no significant differences between groups with regards to any of the other pre- or postoperative variables investigated. The use of nitinol staples vs. traditional plate and screw constructs for stabilizing the pubic symphysis did not result in more clinical failures. The hardware failures identified in the nitinol staple group occurred significantly earlier in the postoperative period, and were associated with a loss of reduction of the pubic symphysis.

使用形状记忆合金钉(镍钛诺)治疗耻骨联合破裂:临床结果和影像学结果。
镍钛诺是一种形状记忆合金,在骨科领域有许多不同的应用。以前没有研究报告使用镍钛诺钉固定耻骨联合的临床或影像学结果。回顾性分析了42例在城市一级创伤中心接受耻骨联合骨折手术稳定治疗的患者。单独使用骨盆钉或结合传统钢板和螺钉治疗的患者与不使用形状记忆合金治疗的患者进行比较。在本次调查中,34例患者(8例订书钉和26例对照组)被纳入最终分析。骨盆钉组8例患者中有3例植入物失败,其中2例复位丢失(25%);这与对照组的7例硬件故障(P = 0.61)没有显著差异,没有任何复位损失(P = 0.17)。与对照组的101.7天相比,镍钛诺钉钉组的失败发生在17.3天较早(P = 0.003)。在其他术前或术后变量的调查中,两组之间没有显著差异。使用镍钛诺固定钉与传统的钢板螺钉固定耻骨联合并没有导致更多的临床失败。在镍钛诺钉钉组中发现的硬体故障在术后发生的时间明显更早,并且与耻骨联合复位的丧失有关。

期刊介绍: MEDICAL IMPLANTS are being used in every organ of the human body. Ideally, medical implants must have biomechanical properties comparable to those of autogenous tissues without any adverse effects. In each anatomic site, studies of the long-term effects of medical implants must be undertaken to determine accurately the safety and performance of the implants. Today, implant surgery has become an interdisciplinary undertaking involving a number of skilled and gifted specialists. For example, successful cochlear implants will involve audiologists, audiological physicians, speech and language therapists, otolaryngologists, nurses, neuro-otologists, teachers of the deaf, hearing therapists, cochlear implant manufacturers, and others involved with hearing-impaired and deaf individuals.
