Abstract:

BACKGROUND: Absorbable material is a new type of internal fixation material in orthopedics, and its application is still a controversy in the clinic. Absorbable materials can degrade by themselves, and can avoid secondary trauma surgery, which exhibit a significant advantage in the treatment of Mason type II radial head fracture.

OBJECTIVE: To explore the short- and long-term effects of the internal fixation using mini-plate, Herbert screw and absorbable rod in the treatment of Mason type II radial head fracture, and to provide guidance for clinical treatment.
METHODS: The clinical data of 93 patients with Mason type II radial head fractures admitted at Department of Joint Surgery, the Second Hospital of Dalian Medical University from March 2010 to February 2016 were collected. All patients received incision and internal fixation surgery using mini-plate (21 cases), Herbert screw (39 cases) and absorbable rod (30 cases). The operative indexes (operation time, intraoperative blood loss), fracture healing time and treatment cost were compared. Visual Analogue Scale and Broderg-Morrey elbow function scores were recorded. The complications were evaluated.
RESULTS AND CONCLUSION: (1) Ninety patients were followed up for 2.2-8.2 years, with an average of 5.1 years. There was no significant difference in the operation time, intraoperative blood loss or fracture healing time among groups (P > 0.05). (2) The Broderg-Morrey scores postoperatively in each group were gradually increased with time (P < 0.05), and the excellent and good rate of scores showed no significant difference among groups (P > 0.05). (3) The postoperative Visual Analogue Scale scores in each group were gradually decreased with time (P < 0.05). The scores in the absorbable rob group at 3 days, 1 and 2 weeks postoperatively were significantly lower than those in the other two groups (P < 0.05). (4) There was no significant difference in the adverse reaction rate among groups (P > 0.05). (5) The treatment costs in the mini-plate and Herbert screw groups were significantly higher than those in the absorbable rod group (P < 0.05). (6) Our findings suggest that absorbable rod for the repair of Mason type II radial head fracture has the similar effect with traditional mini-plate and Herbert screw, but it can effectively alleviate pain and reduce adverse reactions and treatment costs.
