ObjectiveTo observe the effectiveness of open release combined with distal radius fixation hinged external fixation for the treatment of elbow stiffness.MethodsA total of 77 patients with elbow stiffness caused by trauma were enrolled in this study between October 2014 and October 2015. The patients were divided into control group (39 cases) and observation group (38 cases) by random number table method. The patients in the observation group were treated with elbow joint opening and release combined with distal radial fixation hinged external fixation, while the control group was treated with traditional release. There was no significant difference in gender, age, disease causes, original damage diagnosis, the time from injury to operation, preoperative flexion and extension activity of elbow joint, and preoperative Mayo elbow joint function score between 2 groups ( P>0.05). After operation, the function of elbow joint was evaluated by the flexion and extension activity of the elbow joint and the Mayo elbow joint function evaluation standard.ResultsThe incisions healed by first intention in 2 groups. In observation group, there were 1 case infection of nail tract, 2 cases ulnar nerve symptoms, 1 case elbow ossification, and 1 case moderate pain in the elbow; while in control group, there were 2 cases of infection of nail tract, 2 cases of ulnar nerve symptoms, and 3 cases moderate pain in the elbow. The patients in 2 groups were followed up 6 weeks to 12 months, with an average of 6 months. The flexion and extension activity of elbow joint and Mayo elbow joint function score at last follow-up were significantly improved when compared with preoperative ones ( P<0.05); at last follow-up, the flexion and extension activity of elbow joint and Mayo elbow joint function score in observation group patients were significantly better than those in control group ( P<0.05). According to the Mayo elbow function evaluation standard, the results were excellent in 27 cases, good in 10 cases, and fair in 1 case, with an excellent and good rate of 97.4% in observation group; and the results were excellent in 12 cases, good in 21 cases, fair in 4 cases, and poor in 2 cases, with an excellent and good rate of 84.6% in control group; showing no significant difference between 2 groups ( P=0.108).ConclusionOpen release combined with distal radius fixation hinged external fixation can significantly improve the elbow function of patients with traumatic elbow stiffness, its recovery of elbow function was superior to the traditional release.
