[Bone union of distracted region after limb lengthening]
1First Surgery Department, People's Hospital of Liuzhou City, Liuzhou Guangxi, P. R. China 545001.
Objective:
To investigate the factors which affect the bone union of distracted region after limb lengthening, so as improve the curative effect and diminish the incidence of complication.
Methods:
To look up the latest literatures dealing with the bone union in limb lengthening, then review the procedure of osteogenesis and the affecting factors.
Results:
The osteogenesis of distracted region after limb lengthening is a sophisticated procedure. It can be affected by the velocity of lengthening, the period of lengthening, the site and method of osteotomy, the age etiology of patient.
Conclusion:
The bone union of distracted region after limb lengthening can be facilitated by following factors: 1. the velocity of lengthening slower than 1.0 mm/day; 2. moderate delay in distraction; 3. axial shortening of distracted region; 4. micromovement stimulation.
