Abstract:
[Objeetive] To investigate the effect of minimally invasive V-shaped osteotomy instead of traditional operative technique for correction of ankylosing kyphosis.[Method]The C-arm X-ray was used under the local anaesthesia to select the space of osteotomy,the length of incision were 6~8 cm and only exposed one interlaminal space,the width of laminar V-shaped osteotomy were 8~10 mm.The operating table was changed from reverse V to type after finished osteotomy,the space of osteotomy would be automatica ly closed and replaced,if the space could not be automaticly closed,careful manipulation would be applied to close it.The bone mass of osteotomy was used in posterior bone graft of lamina.Postoperation,stric and standardized regulation were performed to send the patient back to ward.The fractional manual correction and external fixation of hyperextended plaster vest were performed respectivly 2 weeks after operation.[Result]Fifty patients of this group acquired more satisfied results except 1 case appeared recurrent deformity due to early removing of the plaster vest.[Conclusion]Minimal damage,lower medical expenses(without internal fixation)and satisfied results demonstrated the minimally invasive V-shaped osteotomy is a very effective method.It has advantages of Mutual intercalated V-shaped osteotomy space and better stability after reduction,posterior bone graft of lamina and external fixation of hyperextended plaster vest,therefore,all patients can acquire the bone graft fusion afer 6 months.
