【摘要】：目的:探討骨折端微動數(shù)字化測控系統(tǒng)在脛腓骨中下段雙骨折外固定支架固定術后早期負重鍛煉中的應用價值。方法:2006年1月至2007年12月收治266例脛腓骨中下段雙骨折患者。男196例,女70例;年齡22~65歲,中位數(shù)47歲;病程1 h至13 d,中位數(shù)3 d;開放性骨折110例,閉合性骨折156例。所有患者的脛骨骨折均為不穩(wěn)定性骨折,均采用外固定支架進行固定,術后7 d內(nèi)患肢制動,僅進行踝關節(jié)活動,術后第8天開始應用骨折端微動數(shù)字化測控系統(tǒng)進行負重鍛煉,設定骨折端微動范圍為0.1~2 mm。術后6周開始對患肢進行X線檢查,2周1次,觀察骨折愈合情況。結果:除49例因設備故障或未按時復診等原因未獲得完整數(shù)據(jù)外,其余217例患者均獲得完整數(shù)據(jù)。212例患者的骨折達到臨床愈合標準,其中6周23例、8周81例、10周85例、12周10例、14周5例、16周4例、18周2例、22周2例,5例骨折不愈合或愈合不良,經(jīng)再次手術內(nèi)固定后愈合。結論:脛腓骨中下段雙骨折外固定支架固定術后,應用骨折端微動數(shù)字化測控系統(tǒng)進行早期負重鍛煉,可精確控制骨折端微動范圍,有利于促進骨折愈合。
[Abstract]:Objective: to investigate the application value of digital measurement and control system of fretting in fracture end in early loading exercise after double external fixation of middle and lower tibia and fibula fracture. Methods: from January 2006 to December 2007, 266 patients with middle and lower tibia and fibula fractures were treated. There were 196 males and 70 females, aged 2265 years (median 47 years), 1 h to 13 days (median 3 days), 110 open fractures and 156 closed fractures. The tibial fractures of all the patients were unstable fractures and were fixed with external fixator. The affected limbs were immobilized within 7 days after operation, and only the ankle joint was moved. On the 8th day after operation, the fretting digital measurement and control system of fracture end was used to carry out load exercise, and the range of fretting at fracture end was set to be 0. 1 渭 m 2 mm.. X-ray examination of the affected limb was performed 6 weeks after operation, and the fracture healing was observed once 2 weeks. Results: with the exception of 49 patients who failed to obtain complete data due to equipment failure or failure to return on time, 217 patients received complete data. 212 cases of fractures reached the standard of clinical healing. There were 23 cases at 6 weeks, 81 cases at 8 weeks, 85 cases at 10 weeks, 10 cases at 12 weeks, 5 cases at 14 weeks, 4 cases at 16 weeks, 2 cases at 18 weeks and 2 cases at 22 weeks. Conclusion: the application of fretting digital measurement and control system for early loading exercise after external fixation of middle and lower tibial and fibula fractures can accurately control the range of fretting at the fracture end and promote fracture healing.
