Usefulness of Morphine in the Periarticular Multimodal Drug Local Injection after Surgery for Hallux Valgus / 대한족부족관절학회지

ABSTRACT

PURPOSE: Proximal metatarsal chevron osteotomy for hallux valgus is followed by significant amount of postoperative pain. Periarticular multimodal drug local injection can be an option for pain control. This study was attempted to evaluate the efficacy of the morphine as multimodal drug and to confirm the effect of periarticular multimodal drug local injection on controlling early postoperative pain. MATERIALS AND METHODS: Between March 2012 and June 2012, 22 patients received proximal metatarsal chevron osteotomy for the correction of hallux valgus deformity. 10 patients (Group A) received periarticular injection of the test solution made with morphine, ropivacaine, ephinephrine and ketorolac. 12 patients (Group B) received periarticular injection of the test solution without morphine. The visual analog scale (VAS) was checked at 2, 4, 6, 8 hours, 1 day and 2 days each after surgery. RESULTS: The VAS score at postoperative 2 hours to 1 day between two groups showed no significant difference, but the VAS score at postoperative 2 days was significantly higher in Group A compared to the VAS score of group B. The amount of additional pain control (tramadol HCL) between two groups showed no significant difference for 3 days after surgery. CONCLUSION: Periarticular multimodal drug local injection was effective in reducing pain after hallux valgus surgery regardless of mixing with morphine.
