RUPENIAN, Pablo R. Minimally invasive plate osteosynthesis (MIPO) for humeral diaphyseal fractures. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2013, vol.78, n.2. ISSN 1852-7434.

Objectives: To show and analyze the treatment of a group of humeral diaphyseal fractures with the minimally invasive plate osteosynthesis (MIPO) technique. Special emphasis was placed in analyzing immediate postoperative pain; delay to return to basic daily activities; time to radiological healing; and complications. Methods: Fifteen humeral diaphyseal fractures were assessed retrospectively. The average age was 57 years (18-84). The average follow-up was 26 months (12-96). Eight cases were treated with anterior MIPO technique using straight implants. Seven cases were treated with MIPO technique using helical implants. Results: Healing was reached in all cases. The average time to radiological healing was 12 weeks (6-32). Excluding one case with delayed union, the average time was 10 weeks (6-16). The average pain score according to the visual analogue scale for the first 48 hours after surgery was 2.4 (1-4). The average time needed to return to basic daily activities was 9 days (4-17). Complications included delayed union (1 case), superficial infection (1 case) and tenosynovitis of the long head of the biceps (1 case). Conclusions: The MIPO technique proved to be a method with a high healing rate requiring the same time or less compared to other osteosynthesis methods. It caused mild immediate postoperative pain and return to basic daily activities was quick. Complications were managed successfully.
