title: [Clinical research progress of direct surgical repair of lumbar spondylolysis in young patients].
abstract: OBJECTIVE
  To review and summarize the surgical techniques and their outcomes for the treatment of lumbar spondylolysis in young patients by direct surgical repair.
  
  
  METHODS
  Both home and abroad literature on the surgical techniques and their outcomes respectively for the treatment of lumbar spondylolysis in young patients by direct surgical repair was reviewed extensively and summarized.
  
  
  RESULTS
  Direct surgical repair of lumbar spondylolysis can offer a simple reduction and fixation for the injured vertebra, which is also in accord with normal anatomy and physiology. In this way, normal anatomy of vertebra can be sustained. As reported surgical techniques of direct repair, such as single lag screw, hook screw, cerclage wire, pedicle screw cable, pedicle screw rod, and pedicle screw hook system, they all can provide acceptable results for lumbar spondylolysis in young patients. Furthermore, to comply strictly with the inclusion criteria of surgical management and select the appropriate internal fixation can also contribute to a good effectiveness. Within the various methods of internal fixation, pedicle screw hook system has been widely recognized.
  
  
  CONCLUSIONS
  Pedicle screw hook system fixation is simple and safe clinically. With the gradual improvement of this method and the development of minimally invasive technologies, it will have broad application prospects.
