Abstract:

BACKGROUND: Surgery is one of the main methods for the treatment of acute scaphoid fracture. But it is still controversial whether percutaneous titanium hollow compression screw internal fixation is reliable for the treatment of non-displaced or slightly displaced scaphoid fractures.

OBJECTIVE: To retrospectively analyze the efficacy of closed reduction and percutaneous hollow compression screw internal fixation in the treatment of scaphoid fractures.

METHODS: Twenty-one patients with scaphoid fractures who received closed reduction and percutaneous hollow compression screw internal fixation surgery in the Department of Traumatology and Orthopedics, Peking University People’s Hospital, China between January 2010 and July 2018 were included in this study. All of them underwent preoperative X-ray and CT examination to make diagnosis and clarify classification. They were followed up for over 3 months. Postoperative X-ray examination was also performed to identify fracture healing. Modified Mayo wrist function score was used to evaluate postoperative efficacy.

RESULTS AND CONCLUSION: Scaphoid fractures healed successfully in all patients, with an average healing time of (9.10±3.03) weeks. The average time for patients to resume daily work or study was (7.00±4.08) days. According to the modified Mayo clinic score, excellent healing was found in 16 patients, good healing in 4 patients, and fair healing in 1 patient, with the excellent and good rate of 95.2%. Patients with Herbert type B1 (n=6) had lower postoperative Mayo pain score than those with A2 (n=5) and B2 (n=10) (P < 0.05). This indicates that patients with B1 type had more postoperative pain. Results from this study suggest that closed reduction percutaneous titanium hollow compression screw internal fixation surgery is reliable in the treatment of acute scaphoid fracture. This study was approved by Medical Ethics Committee, Peking University People’s Hospital, China.
