摘要

本研究自1989年至1991年間，以低溫成型塑膠材料（low temperature thermoplastics）製作功能性骨折支架治療5例肱骨骨折和１例尺骨病理性骨折。另外以同種材料製作脊椎背架治療3例腰椎骨折。所有肱骨骨折的病患，在８至 12週間骨折均癒合，其內翻角變形平均為7°，前翻角變形平均為8°。關節活動度方面，除1例外均有良好的活動度。尺骨病理性骨折之病患，在使用功能性骨折支架固定後，手部功能良好，且活動時沒有任何疼痛。所有腰椎骨折的病患，在20週時骨折均癒合。
由本研究所得之結果顯示，此種以低溫成型的骨折丈架不但輕巧堅固，在使用上比傳統高溫定型骨折支架方便省時。更因其可在病患身上直接成型，所以支架更合身，而且可按病情變化隨時作修改。

From 1989 to 1991, five cases of humeral shaft fractures and one case of ulnar shaft pathological fracture were treated with the low temperature thermoplastic functional fracture brace, while three cases of lumbar spine fractures were treated with a　custom-made spinal brace molded by low temperature thermoplastics.
All patients with humeral shaft fractures achieved bone healing within 8 to 12 weeks. There was varus angulation averaging 7°and anterior angulation averaging 8°present. The majority of patients were found to have minimal loss of range of motion in the shoulder. In the case of the patient with pathological ulnar shaft fracture, functional movement of the hand was good and no pain was detected. In all cases with lumbar spine fractures, healing of the bone was obtained at 20 weeks.
These findings indicate that management of patients using low temperature thermoplastic fracture braces achieve greater benefits in the treatment of humeral shaft fractures versus using a brace made of the traditional high temperature materials. By using direct molding onto the patient, this proved to provide better individual fitting and thus, according to the healing process of the fracture, periodic remolding could be easily accomplished.
