Inclusion criteria
Inclusion criteria: 1. Adult patients (aged 18 years or older); 2. Acute traumatic fractures with an injury-to-surgery interval of less than 3 weeks; 3. Fractures limited to long bones in the extremities(lupper limb:clavicle, humerus, ulna, and radius. lower limb:femur, tibia, and fibula); 4. Utilization of fixed-angle locking plates featuring dedicated locking holes; 5. Constructs manufactured from titanium alloy or medical-grade stainless steel; 6. Preshaped plates designed to conform to anatomic templates; 7. Locking head screws with diameters ranging from 2.4 to 6.5 mm; 8. Postoperative orthogonal radiographs (anteroposterior and lateral projections) were utilized to evaluate the locking state of screws.
Exclusion criteria
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.
