The interlocking nail is used as a valuable method in treating humerus shaft fracture because of the merit, including relatively simple procedure, one of the most stable fixation methods, and allowing early ROM excericise and low complication.
Fourteen pateints with humerus shaft fractures were treated using interlocking nil at the Department of Orthopaedic Surgery Paik Hospitalfrom Jan, 1993 to Oct. 1994.
1. Among the 14 pateints, average age was 34.8 years and 9 cases were male and the most common cause of injury was traffic accident.
2. Associated injury including 3 cases of ipsilateral scapular fracture, 1 case of ipsilateral clavicle fracture, and 1 cases of brachial plexus injury, and 1 case of radial nerve injury.
3. The mean duration of the radiologic bone union was 8l.6 weeks.
4. There was no serious post operative complication such as non-union, infection, bending or rotational deformity at fracture site, impingement syndrome, metal failure of the nail or interlocking screws.
5. To prevent the impingement syndrome and rotator cuff injury, we countersinked the proximal end of the nail into the humeral head and minimized skin incision.
