A low incidence of humeral nonunions has been reported with predisposing factors listed as inadequate immobilization, open reduction and internal fexation, infection, distraction, transverse fractures, and significant soft tissue injury. when
nonunion
occurs, the humerus is often osteoporotic, with rigid fixation difficult to achieve and prone to faiure. Many methods of treatment have been employed for this difficult problem.Authors have experienced 9 cases of nonunion of humiral shaft
fracture
and
accomplished solid union in all cases by osteosynthesis accompanied by autogenous bone graft.
@ES The results were as follows:
@EN 1. Of the 9 cases, male were 7, female were 2. Prevalent site was found mostly at the middle 1/3
2. Initial treatment were surgical in 7 out of 9 cases, and on retrospective analysis of medical records and X-ray films, probable cause of the nonunion were supposed to be too early performed inadequat internal fixation.
3. The treatment performed were somewhat to included open reduction and rigid plate fexation for 8 cases, and open reduction and intramedullary nailing for 1 cases. All were suplemented with autogenous iliac bone graft.
4. 4. Union was obtained in all cases. All were united at average 4.9 months.
5. Postoperative immobilization was done for average 8.7 werks. Limitation of motion of
shoulder and elbow in 3 cases, which required considerable time of physical therapy.
