Abstract

Abstract:

BACKGROUND: Open reduction and internal fixation is commonest surgical method for calcaneal fractures, but its postoperative complications are troublesome. Thereafter, choosing an appropriate treatment scheme is of great significance for reducing postoperative complications and promoting patients’ functional recovery.

OBJECTIVE: To compare the curative efficacy of the modified minimally invasive internal fixation with cannulated screws through tarsal sinus and traditional extended lateral “L-shape” incision with plate fixation for calcaneal fractures.

METHODS: Sixty-eight cases of unilateral calcaneal fractures (Sanders II and III) were selected, followed by treated with modified minimally invasive internal fixation with cannulated screws through tarsal sinus (modified group, n=33) or traditional extended lateral “L-shape” incision with plate fixation (traditional group, n=35). The operation time, blood loss, and Visual Analogue Scale scores were compared between two groups; the preoperarive and postoperative American Orthopedic Foot and Ankle Society scores, Bohler angle, and Gissane angle as well as postoperative complications were detected and compared between both groups. Besides, the postoperative pain, range of motion, and ankle stability were evaluated.

RESULTS AND CONCLUSION: (1) The American Orthopedic Foot and Ankle Society scores at 6 months postoperatively in both two groups were significantly higher than those at baseline, and the scores in the modified group were significantly higher than those in the traditional group (P < 0.05). (2) The Bohler angle, Gissane angle, and calcaneal width in the modified group were significantly improved compared with the traditional group at 1 week, 6 and 12 months postoperatively (P < 0.05). (3) Compared with the traditional group, the operation time, blood loss, and Visual Analogue Scale scores in the modified group were significantly improved (P < 0.05). (4) The incidence of complications in the modified group was significantly lower than that in the traditional group (P < 0.05). (5) These results manifest that compared with the traditional extended lateral “L-shape” incision with plate fixation for calcaneal fractures, the modified minimally invasive internal fixation with cannulated screws through tarsal sinus can significantly alleviate pain, and improve the range of motion and stability of the ankle joint.
