Effectiveness of Hip Arthroscopy Performed Simultaneously before Open Reduction and Internal Fixation for Acetabular Fracture and Fracture-dislocation of the Hip / 대한고관절학회지

ABSTRACT

PURPOSE: This study is performed to evaluate the usefulness of arthroscopic surgery prior to open reduction and fixation surgery to treat acetabular fractures and hip fractures-dislocation. MATERIALS AND METHODS: From January 2010 to March 2014, a total of 54 patients with acetabular fractures or hip fractures with dislocation were treated arthroscopically via fracture surface before open reduction and fixation (group 1, n=11), and without hip arthroscopy prior to open reduction and fixation (group 2; n=43). Clinical results were evaluated using Harris hip score (HHS) and visual analogue scale (VAS) pain scores. RESULTS: The mean age of patients is 43.2 years and there are 10 males and 1 females in group 1. The mean follow-up period is 15 months. The acetabular status of each case was assessed arthroscopically. Bone fragment was performed in 6 cases, and ligamentum teres shrinkage in 1 case. At the final follow up, the mean HHS and VAS pain scores were 78.6 and 2.18, respectively. During follow up, one case of osteoarthritis and one case of heterotopic ossification were identified. At the final follow up, the mean HHS and VAS pain scores were 77.5 and 2.23, respectively. In group 2, oteoarthritis and ectopic ossification were observed in 4 and 1 cases, respectively. CONCLUSION: No differences were observed in the clinical outcomes of patients with acetabular fracture or hip fracture-dislocation when treated with or without arthroscopic surgery before open reduction and fixation. However, arthroscopy is thought to be useful for evaluating the joint cartilage surface and fracture fragments more accurately.
