Abstract:
Objective:To investigate the clinical efficacy of minimally invasive percutaneous internal fixation with double screws for delayed union or nonunion of scaphoid fracture.Methods:A retrospective study was conducted to analyze the 12 patients with delayed union or nonunion of scaphoid fracture who had been treated at Department of Hand and Foot Surgery, The Affiliated Hospital of Jining Medical University from March 2021 to December 2023. They were 11 males and 1 female, with an age of (29.9±13.8) years and an interval from injury to surgery of (5.1±2.6) months. They were all treated by minimally invasive percutaneous internal fixation with 2 hollow compression screws. The visual analogue scale (VAS), grip strength (percentage of the affected side to the healthy side), wrist range of motion, modified Mayo wrist score and other data were recorded and compared between pre-surgery and the last follow-up. The incidence of complications was recorded.Results:Follow-up for all patients lasted for (20.8±8.9) months. All patients achieved bony union after (10.1±3.2) weeks with no complications like infection. No post-surgery imaging revealed screw misplacement or penetration. At the last follow-up, the VAS pain score was 0 (0, 1) point, the wrist grip strength 100.6%±7.2%, the wrist flexion 88.3°±2.5°, the wrist dorsiflexion 88.5°±2.2°, and the modified Mayo wrist score (98.3±2.5) points, all significantly better than the pre-surgery values [4 (4, 5) points, 69.1%±16.0%, 61.3°±13.5°, 64.7°±9.1°, and (61.7±10.1) points] (all P < 0.05). Conclusion:In the treatment of delayed union or nonunion of scaphoid fracture, minimally invasive percutaneous internal fixation with double screws shows advantages of minimal invasion, quick fracture healing, fine functional recovery, and no need of bone grafting.
