摘要
采用穿针外固定，配合患肢负重功能锻炼治疗胫骨骨不连２２例。其中，１０例增殖型，１２例萎缩型。究其原因，１１例为内固定不良，４例为石膏、２例为自制夹板固定而达不到固定效果，５例为骨端感染所致。治疗经过８７～１８９天，平均１０３天，１９例在６个月内愈合，３例效果欠佳。疗效分析认为：骨不连主要由于不良治疗过分干扰骨折自然愈合过程，骨生长能力受到限制所致，弹性外固定可改善骨折端稳定性，提供弹性和间断生理压应力，不限制功能锻炼中肌泵的供血作用，有利于骨端生长能力的恢复。
Twenty-two cases of non-union of tibia treated by external fixation with wire and functional exercise under burder. Among them, 10 cases were proliferative type,12 atrophic type.The causes of tailure are 11 cases for defext in internal fixation,4 for plaster of Paris fixator, 2 for self-made splint fixation with bad fixation,and 5 for infection of the fracture ends.Through a course of therapy from 87-189 days,with an average of 103 days,19 cases healed within months,3 with worse effectiveness. The result of analysis showed that,the maincause of non-union was due to insufficient therapy interference to natural healing process,with limitation of the ability of bone growth.Elasticexternal fixation can improve the stability of fracture ends,offer elastic and interrupted physiological pressure stress.It dons't limit the blood supply action of the muscle pump during functional exercies.It facilitaes recovery the ability of growth of the fracture ends.
