Abstract:
Objective:To investigate the application value of cannulated screws in the treatment of Hauck type Ⅱ ulnar styloid process fracture.Methods:The clinical data of 93 patients with Hauck type Ⅱ ulnar styloid process fracture who received treatment at Fuzhou Second Hospital Affiliated to Xiamen University from December 2020 to February 2023 were retrospectively analyzed for a case-control study. Among these patients, 38 patients did not undergo surgical fixation and 55 patients underwent surgical fixation. Twenty-seven patients underwent surgical fixation with cannulated screws and twenty-eight patients underwent surgical fixation with Kirschner wires. The fracture healing, postoperative rehabilitation, and functional recovery of the wrist were compared among groups.Results:The fracture healing rate and the incidence of distal radioulnar joint instability in the surgical fixation group were 100.00% (55/55) and 5.45% (3/55), respectively. These were significantly higher and lower respectively compared with the non-surgical fixation group [57.89% (22/38), 50.00% (19/38), χ 2 = 27.66, 24.69, both P < 0.001]. The wrist function recovery in the surgical fixation group was significantly superior to that in the non-surgical fixation group ( Z = -5.18， P < 0.001). There were no statistically significant differences in operative time and intraoperative blood loss between the cannulated screw group and the Kirschner wire group [(21.41 ± 5.15) minutes vs. (20.93 ± 5.71) minutes, (2.11 ± 0.97) mL vs. (2.07 ± 0.90) mL, t = 0.32, 0.15, both P > 0.05]. The fracture healing time and rehabilitation intervention time in the cannulated screw group were shorter than those in the Kirschner wire group [(6.48 ± 1.05) weeks vs. (9.14 ± 1.24) weeks, (2.11 ± 0.32) weeks vs. (3.11 ± 0.57) weeks, t = 8.57, 7.98, both P < 0.001]. The postoperative wrist function scores in the cannulated screw group were superior to those in the Kirschner wire group ( Z = -2.21, P < 0.05). Conclusion:For patients with Hauck type Ⅱ ulnar styloid process fracture, surgical fixation can promote the recovery of wrist function after surgery, and cannulated screw fixation is an effective method for the treatment of Hauck type Ⅱ ulnar styloid process fracture.
