Abstract
Aim
Treatment for distal third shaft fractures of humerus is very challenging especially if its comminuted and bone is osteopenic. They are commonly treated with plating. Plating has complications of iatrogenic radial nerve palsy. We report our case series of distal third fractures of humerus treated with retrograde Halder Humeral Nail.
Materials and methods
Since 1994 to 2010 we have 576 fractures of humerus treated with retrograde Halder Humeral nail. Of these 45 were distal third extra articular fractures of humerus. Average age of patients at the time of surgery was 30.4 years (Range 15–82 years, Median 33 years). Of 45 patients 26 were females and 19 males.3 out of 45 had non union at the time of presentation. The nail was locked distally with one or two screws and proximally with a screw and tripwire. The entry point of the nail was roof of olecranon fossa (contrary to standard retrograde nails where it is an inch above olecranon fossa) This design of nail allows it be used for even very distal fractures. All patients were followed till clinical and radiological signs of union. 1 patient was lost to follow up.
Results
Average time to fracture healing was 13.9 weeks (Range 9–36 weeks). There were 2 cases of non union, one healed at 9 months with 2nd surgery. The other non union was asymptomatic and did not agree for further surgery. There was one reported case of infection.7 patients had nail removal electively on request. All the patients achieved full range of elbow and shoulder movement. No reported cases of iatrogenic radial nerve palsy.
Conclusion
Our results of distal third fractures of humerus treated with retrograde Halder Humeral Nail are excellent. It avoids big exposure as needed in plating and complication of iatrogenic radial nerve palsy.
