IntroductionHumeral shaft fractures are a common injury of the upper limb, with the primary surgical treatment modality being the locking compression plate (LCP) technique. The advent of Anterior medial minimally invasive plate osteosynthesis (MIPO) technology has led to its gradual implementation in clinical practice. However, the efficacy and long-term outcomes of MIPO require further investigation. The objective of this study is to compare the therapeutic effects of LCP and MIPO in the management of humeral shaft fractures.MethodsThe present study conducted a retrospective review of patients diagnosed with humeral shaft fractures between June 2016 and December 2019. The patients were divided into MIPO and LCP groups based on the different surgical methods. The study analyzed the length of hospital stay, radiation exposure, operative time, and postoperative Disabilities of the Arm, Shoulder and Hand (DASH) scores using statistical methods.ResultsA total of 53 patients who met the inclusion criteria were included in the study. The MIPO group demonstrated a statistically significant reduction in length of hospital stay compared to the LCP group (length of hospital stay: 5.39 ± 2.23 days vs 12.00 ± 7.19 days, P < 0.001). All patients achieved callus formation after surgery. However, the MIPO group had significantly more radiation exposures than the LCP group (45.96 ± 19.49 vs 5.33 ± 2.20, P < 0.001). Additionally, there was no statistically significant difference observed in the time from admission to surgery, operative time,and healing time between the two groups (the time from admission to surgery: P = 0.593; operative time: P = 0.407; Healing time: P = 0.664). During the postoperative follow-up, the MIPO group exhibited significantly lower 6-week and 3-month DASH scores compared to the LCP group (6-week: 34.17 ± 12.16 vs 45.65 ± 22.94, P = 0.028; 3-month: 17.43 ± 11.70 vs 30.12 ± 9.80, P < 0.001). However, there was no statistically significant difference in the 6-month and 12-month DASH scores between the two groups (6-month: P = 0.787; 12-month: P = 0.058).ConclusionThe MIPO technique provides better short-term functional recovery of the shoulder and elbow compared to the LCP technique in the treatment of humeral shaft fractures, while ensuring equivalent surgical healing.Copyright © 2024.
