Abstract
The authors report two cases of the treatment for pathological fracture of a proximal humeral bone cyst with a novel method using several Kirschner wires (multiple pinning methods).
One of 2 patients, aged 5 and 13 years, had solitary bone cysts in active phase. The radiologic appearance in all cases was a large lytic defect with pathological fracture in the proximal metaphysis of the humerus. One of the patients had a recurrence of the cyst after conservative treatment at another hospital. The duration of follow-up after surgery ranged from 15 to 18 months. All patients showed pain relief, normal joint function, no migration of wires, and complete or incomplete healing of the lesion without recurrence.
We believe that the procedure provides good fixation of fracture and pain relief in the early stage after surgery. Moreover, there is radiological evidence for the continuous decompression effect by Kirschner wires to heal solitary bone cysts.
