Abstract:

BACKGROUND: The recovery process, wrist join function and resetting quality of different fixation methods for type C distal radial fractures are different. The comparisons among different fixation methods are lack of sufficient evidence, and there is still some controversy.  
OBJECTIVE: To investigate the effects of Kirschner wire external fixator, external fixator and volar approach plate internal fixation on the recovery process, wrist join function and resetting quality of type C distal radius fractures patients.
METHODS: The clinical data of type C distal radius fracture patients who were treated in Hainan Provincial People’s Hospital from January 2016 to December 2017 were retrospectively analyzed. Totally 93 patients were followed up. Among them, 32 patients underwent Kirschner wire external fixator fixation (Kirschner wire external fixator group), 21 patients underwent external fixator fixation (external fixator group), and 40 patients underwent volar approach plate internal fixation (volar approach plate internal fixation group). All patients signed informed consent. This study was approved by the Hospital Ethics Committee. The clinical operation indexes, recovery process, excellent and good rate of wrist joint function and fracture reduction quality of the three groups were compared and analyzed. The patients’ satisfaction and complications were recorded.
RESULTS AND CONCLUSION: (1) The operation time, hospitalization time and fracture healing time of Kirschner wire external fixator group and external fixator group were shorter than those of volar approach plate internal group (F=200.589, 100.379, 14.282, all P < 0.05). (2) At 6 months after operation, the excellent and good rate of wrist joint in volar approach plate fixation group was higher than that in Kirschner wire external fixator group and external fixator group (χ2=6.541, P < 0.05). (3) At 12 months after operation, the palmar inclination and ulnar deviation of the volar approach plate internal fixation group were greater than those of the Kirschner wire external fixator group and external fixator group (F=87.622, 33.077, all P < 0.05). (4) The incidence of complications in Kirschner wire external fixator group and external fixator group was lower than that in volar approach plate internal fixation group (χ2=6.455, P < 0.05). (5) Results suggested that the clinical effects of three fixation methods for patients with type C distal radius fractures are satisfactory. Among them, the Kirschner wire external fixator and external fixator have the advantages of shorter operation time, shorter quicker healing, and lower incidence of complications. The resetting quality of the Kirschner wire external fixator is better than that of external fixator. While the volar approach plate internal fixation owns higher early good rate and better resetting quality.
