Abstract

Abstract:

BACKGROUND: Acetabulum fracture is an intra-articular fracture. The acetabulum has a deep position, irregular shape and is adjacent to many important blood vessels and nerves. The purpose of treatment is to recover the anatomical contraposition of acetabulum joint surface accurately and to maximize the function of the hip retained. The digital technology has a guiding significance to the treatment of the acetabulum fracture.
OBJECTIVE: To investigate clinical therapeutic effect of internal fixation with the assistance of digital technology on acetabulum fracture.
METHODS: 50 patients with acetabulum fracture were recruited from Department of Orthopedic Trauma, Guangzhou General Hospital of Guangzhou Military Command of Chinese PLA between March 2009 and September 2011. The involved patients were divided into control group and study group randomly. 25 cases of study group received preoperative plans through the digital technology and treated with open reduction and internal fixation according to the plans. 25 cases of control group were treated with operations only. The amount of bleeding during the operations, the duration of the operations, the duration of hospitalizations and the function evaluation after the operations were compared between the two groups.
RESULTS AND CONCLUSION: 23 cases had been followed up from 13 to 24 months in the study group and 24 cases had been followed up from 12 to 26 months in the control group. The amount of bleeding during the operations and the duration of the operations in the study group were significantly lower than that in the control group (P < 0.05). The duration of hospitalizations and the healing time of the fracture after the operations were significantly shorter in the study group than in the control group (P < 0.05). The hip function scores after the operations in the study group were significantly higher than that in the control group (P < 0.05). Using the digital technology we reconstruct the three-dimensional models of acetabulum fracture before surgeries can help imitating the fracture reductions and formulating the individualized operation plans. It has satisfactory effect to treat the patients with open reduction and internal fixation surgeries according to the plans.
