研究目的:

锁定钢板接骨术是最广泛使用的骨折固定方法之一。然而,锁定头螺钉的非标准放置仍然是一个问题。本研究旨在介绍一种新的分类方法,并描述上肢和下肢长骨骨折锁定板接骨术中假锁现象的流行病学研究。  

Objectives of Study:

Locking plate osteosynthesis is one of the most widely used methods for fracture fixation. However, the nonstandard placement of locking head screws remains a concern. The present study aims to introduce a new classification and describe the epidemiology of the pseudolock phenomenon in upper limb and low limb locking plate osteosynthesis.

纳入标准:

Inclusion criteria

排除标准:

1.18岁以下患者 2.非急性骨折(手术间隔损伤超过3周)、肿瘤引起的病理性骨折、假体周围骨折或影响骨形态的先天性畸形(如成骨不全、软骨发育不全) 3.涉及指骨、掌骨、肩胛骨、盆骨、跟骨、距骨、跖骨、趾骨的骨折 4.使用非轴向载荷设计的远端锁定螺钉、皮质螺钉或松质骨螺钉(完全或部分螺纹) 5.使用没有专用锁孔的锁定板(例如,限触的动态压缩板) 6.使用可变角度锁定板,或者桥接系统 7.术后成像不足或影像资料缺失,无法评估螺钉锁定状态 8.锁定头螺钉直径小于2.4毫米或大于6.5毫米 9.使用非金属结构(如碳纤维、聚醚醚酮材料) 10.使用三维打印板或定制的锁定板

Exclusion criteria:

1. Patients under 18 years of age; 2. Non-acute fractures (injury-to-surgery interval exceeding 3 weeks), pathological fractures due to neoplastic processes, periprosthetic fractures, or congenital malformations affecting bone morphology (e.g., osteogenesis imperfecta, achondroplasia) ; 3. Fractures involving the finger bones, metacarpals, scapula, pelvic ring, talus, calcaneus, metatarsals, or phalanges; 4. Use of distal locking screws with non-axial loading designs, as well as cortical or cancellous screws with full or partial threads; 5. Plates lacking dedicated locking holes (limited-contact dynamic compression plates); 6. Variable-angle locking plates (VA-LCP) or ortho-bridge system (OBS); 7. Non-metallic locking constructs (polyetheretherketone/carbon fiber composites); 8. 3D-printed or customized plates; 9. LHS outside of the 2.4–6.5 mm diameter range; 10. Inadequate postoperative imaging failing to evaluate the locking state of screws.
