Twenty-nine cases of fracture of the humeral shaft were treated for the past 11 years (between 1971 and 1981).
Eighteen cases of those were observed clinically and roentogenologically. Conservative treatment was done for 9 cases. Hanging cast was used for 4 cases of spiral and oblique fractures, traction and shoulder spica cast for 4 cases and shoulder spica cast for 1 case. All cases showed good result.
Surgical treatment was done for 9 cases. Five cases of those were transverse fractures. Two cases resulted in psudoarthorosis. From our result, we suggest that the majority of cases should be treated conservatively except for the cases of transverse, open fracture or the case with radial nerve injury.
