Abstract
Objective: To investigate the effect of minimally invasive locking plate internal fixation on fracture healing and functional recovery in patients with proximal humerus fractures. Methods: 98 patients with proximal humerus fractures admitted to the hospital from August 2021 to July 2023 were selected and divided into the control group (n = 49) and the observation group (n = 49) according to the lottery method. The control group implemented conventional treatment, and the observation group implemented minimally invasive locking plate internal fixation. The treatment effect and complications, surgery-related indexes, and functional recovery of the shoulder joint in the two groups were compared. Results: Compared with the control group, the observation group (97.96%) had a better therapeutic effect than the control group (73.47%) (χ2 = 12.000, P < 0.05); the complication rate of the observation group (2.04%) was lower than that of the control group (18.37%) (χ2 = 7.127, P < 0.05); the fracture healing rate of the observation group (97.96%) was higher than that of the control group (81.63%) (χ2 = 7.127, P < 0.05). The operation time of the observation group (74.25 ± 10.30 minutes) was shorter than that of the control group (115.63 ± 20.30 minutes) (t = 12.725, P < 0.05), the intraoperative bleeding of the observation group (177.30 ± 19.63 ml) was less than that of the control group (306.63 ± 30.62 ml) (t = 24.890, P < 0.05). The fracture healing time was shorter in the observation group (12.30 ± 2.30 weeks) than in the control group (16.23 ± 2.66 weeks) (t = 7.823, P < 0.05), and the hospitalization time was shorter in the observation group (9.30 ± 0.99 days) than in the control group (12.66 ± 2.20 days) (t = 9.749, P < 0.05). Compared with the control group, the pain, muscle strength, activity function, and activity score of the observation group were significantly different (t = 6.398, 12.817, 8.386, 7.892, P < 0.05); compared with the control group, the observation group’s abduction, forward flexion, external rotation, internal rotation, and posterior rotation were significantly different (t = 3.042, 2.843, 3.633, 4.669, 9.176, P < 0.05). Conclusion: Minimally invasive locking plate internal fixation for proximal humerus fracture can adjust its surgery-related indexes, increase the patients’ shoulder joint mobility, enhance the shoulder joint function, improve the fracture healing rate and therapeutic effect, and reduce the complications, which is worth recommending in clinical practice.
