Children’s old Monteggia fracture: Annular ligament reconstruction or not?

Abstract

Abstract:

BACKGROUND: Radial head re-dislocation is one of the alarming complications of old Monteggia fracture. Many treatment methods have described the necessary of fracture and annual ligament reconstruction during treatment, but still unclear.
OBJECTIVE: To emphasize the practicality of annular ligament reconstruction through comparing the children’s treatment in two groups.
METHODS: Twelve patients with children’s old Monteggia fracture were included for retrospective analysis. All the patients were treated with radial head open reduction and internal fixation. Among them, five cases received ulna extending osteotomy and annual ligament reconstruction, and seven cases received ulna extending osteotomy without annual ligament reconstruction. The course was 3-18 months from damage to the clinical manifestations (an average of 9 months). Ten cases with Bado type Ⅰ and two cases were Bado type Ⅱ and Ⅲ. The reliability of ligament reconstruction was evaluated before and after treatment with Kim standard.
RESULTS AND CONCLUSION: All the 12 cases were followed-up for 22 months (8-26 months). Evaluation according to the Kim standard after treatment showed excellent in 10 cases without abnormalities and pain, the range of motion > 250 °, and no elbow was limited, the activities of daily living was 25 points; good in two cases with mild deformity and mild or intermittent pain, the range of motion was 200°-250° with elbow limited, activities of daily living was 15 points; no poor (serious deformity, pain, range of motion < 200°, elbow severely limited, activities of daily living was 0 points). Followed-up lasted for 22 months and found that the average healing time of ulnar osteotomy was 8 weeks (6-14 weeks). The wounds were healed primarily without infection and nonunion. The results indicate that ulna extending osteotomy has great significance in keeping stability of radial head, and annular ligament reconstruction is determined by the time of injury, surgical procedures and intraoperative radial head stability.
