External fixation of thermoplastic plate brace versus gypsum for treating Colles fracture: a randomized controlled trial

doi:10.3969/j.issn.2095-4344.1752

Abstract

Abstract:

BACKGROUND: The new medical thermoplastic plate brace has been widely used for the external fixation of limb fractures, and has achieved some curative effects. But there is still no prospective randomized controlled study on its efficacy in the distal radius fractures needing for manual reduction.

OBJECTIVE: To compare the clinical efficacy of manual closed reduction thermoplastic plate brace and gypsum external fixation in the treatment of Colles fracture by prospective randomized control.

METHODS: One hundred and twenty patients with Colles fractures from January 2016 to January 2018 at the Department of Orthopedics, Central South University Xiangya School of Medicine Affiliated Haikou Hospital were enrolled, including 52 males and 68 females, aged 18-65 years. The patients were randomly divided into two groups and treated with manual closed reduction and thermoplastic plate brace external fixation (thermoplastic plate group, n=60) and manual closed reduction gypsum external fixation (gypsum group, n=60). The complications during treatment were recorded. At 3 and 6 months after treatment, the Visual Analog Scale scores were assessed. At 6 months after treatment, the Gartland-Werley scoring system was used to assess the wrist function and to assess patient satisfaction. Imaging assessment of reduction and fracture healing was performed at immediately, 6 weeks and 6 months after treatment. The study was approved by the Ethics Committee of Central South University Xiangya School of Medicine Affiliated Haikou Hospital, approval number: 2014-308.

RESULTS AND CONCLUSION: (1) The incidence of reactions to the host in the thermoplastic plate group was lower than that in the gypsum group (13.3%, 36.7%, P < 0.05). (2) The Visual Analog Scale scores at 3 and 6 months after treatment in the thermoplastic plate group were lower than those in the gypsum group (P < 0.05). (3) The excellent rate of wrist function and patient satisfaction in the thermoplastic plate group were higher than those in the gypsum group (excellent rate: 88.3%, 73.3%; satisfaction: 91.7%, 65.0%, P < 0.05). (4) The imaging examination showed that the radial height, palmar tilt angle, and ulnar inclination angle in the two groups were significantly better than before treatment, and there was no significant difference between two groups (P > 0.05). (5) These results show that the use of thermoplastic plate brace and gypsum external fixation for treating Colles fracture can obtain satisfactory reduction effect, but the thermoplastic plate has the advantages of simple operation, low incidence of complications, good recovery of wrist function and high patient satisfaction.
