Abstract
OBJECTIVE: To compare the effectiveness of transosseous tunnel fixation and drilling fixation for repair of lateral collateral ligament complex (LCLC) in treatment of terrible triad of elbow (TTE). METHODS: A clinical data of 50 patients with TTE between June 2012 and January 2018 were retrospectively analyzed. The LCLC was repaired with transosseous tunnel fixation in 22 patients (transosseous tunnel fixation group) and with drilling fixation in 28 patients (drilling fixation group). There was no significant difference between the two groups ( P>0.05) in gender, age, fracture side, time from injury to admission, coronoid process fracture classification, radial head fracture classification, and TTE classification. The operation time, intraoperative blood loss, fracture healing time, and complications of the two groups were recorded. At last follow-up, the Mayo elbow performance system (MEPS) score, range of motion of elbow joint, and Broberg-Morrey classification were recorded. RESULTS: The operation of two groups were successfully completed. There was no significant difference in the operation time and intraoperative blood loss between the two group ( P>0.05). The follow-up time was (24.43±6.84) months in the transosseous tunnel fixation group and (21.55±6.16) months in the drilling fixation group, and the difference was not significant ( t=1.534, P=0.132). X-ray films showed that the coronoid process and radial head fractures in the two groups healed, and there was no significant difference in the healing time ( P>0.05). At last follow-up, there was no significant difference in the flexion-extension activity, rotation activity, MEPS score, and Broberg-Morrey grading ( P>0.05). During the follow-up, there was no re-dislocation or instability of the elbow joint. The incidence of complication was 28.57% (8/28) in the transosseous tunnel fixation group and 27.27% (6/22) in the drilling fixation group, showing no significant difference ( χ 2=2.403, P=0.121). CONCLUSION: Both transosseous tunnel fixation and drilling fixation can achieve good results in repair of LCLC for TTE.
