Clinical Effectiveness of the Plate Screw Internal Fixation Technique in the Treatment of Patients with Traumatic Fractures of Long Bones in the Lower Extremities

Objective: To investigate the effectiveness of the plate screw internal fixation technique on the clinical outcomes of patients with traumatic fractures of long bones in the lower extremities. Methods: From January 2022 to December 2023, 70 patients with traumatic fractures of long bones in the lower extremities were admitted to the hospital and randomly divided into two groups: the control group and the observation group, each consisting of 35 cases. The control group underwent traditional closed interlocking intramedullary nailing, while the observation group received internal fixation with steel plates and screws. Relevant surgical indicators, treatment effectiveness, and postoperative complication rates were compared between the two groups. Results: The observation group exhibited significantly short surgical duration (80.65 ± 5.01 vs. 88.36 ± 5.26 minutes), fracture healing time (13.27 ± 0.32 vs. 15.52 ± 0.48 weeks), and hospitalization days (10.49 ± 1.13 vs. 16.57 ± 1.15 days) compared to the control group (P = 0.000). The effective treatment rate was significantly higher in the observation group (29/82.86%) than in the control group (21/60.00%), with a significant difference observed (χ2 = 4.480, P = 0.034). Additionally, the complication rate in the observation group (2/5.71%) was significantly lower than that in the control group (8/22.86%), with a correlated difference (χ2 = 4.200, P = 0.040). Conclusion: The plate screw internal fixation technique demonstrates significant clinical efficacy in treating traumatic fractures of long bones in the lower extremities. It improves the healing rate, reduces complications, and represents a safe and effective treatment strategy worthy of widespread use and application.

肩胛骨骨折内固定物的应用回顾

肩胛骨骨折(scapular fracture,SF)大多为严重的钝性暴力所致,占肩部骨折的3%~5%,多发伤的5%~10%,在全身所有骨折中<1%,其中涉及肩胛体和肩胛冈约50%,盂颈部约20%~25%,关节盂部约10%,肩峰约8%,喙突约7%,浮肩约占<0.1%[1~3]。该部位骨折因暴力大,骨折多不稳定。对于不稳定性肩胛骨骨折,手术治疗越来越成为骨科医生的共识[4~6]。目前手术固定以重建接骨板为主,或以其它部位接骨板替代固定[7~9],也有根据固定肩胛骨不同区域而设计的接骨板[10~13],选择多样,各有利弊。肩胛骨的不规则性及骨折的多样性,使肩胛骨骨折的内固定物选择不尽如意,本文总结肩胛骨骨折的主要内固定物种类,探讨不同类型肩胛骨骨折所需内固定物,以便服务于肩胛骨骨折的内固定物选择。
