小児上腕骨近位端骨折の治療経験

抄録

Proximal humeral fractures in children may develop the axial rotational deformity or the growth disturbance of the upper humeri. In this study, the functional result of 7 cases with this fracture was investigated clinically and radiologically.
All patients injured at the age of between 6 and 14 years were treated conservatively in six with zero-position casting or traction, in the other one with abduction pillow. In each case, shoulder functions such as pain, range of motion and abductor muscle power were examined clinically, and the humeral length discrepancy (HLD) and the neck-shaft angle of the humeri were measured radiologically.
As the result, the shoulder function at the average of 6 years after injury showed no significant insufficiency compared with the sound side. Radiological examination revealed that the HLD was less than 9mm in all cases and the neck-shaft angle improved with age.
From these results, it is suggested that the treatment of this fracture was good.
