BACKGROUND: The incidence rate of spondylolysis of lumbar vertebral arch in recruits is higher during the training, and it affects the normal training. OBJECTIVE: To analyze the correlation of the incidence rate of spondy lolysis of lumbar vertebral arch with training and the original lesions at waist in recruits. DESIGN: A randomized sampling survey. SETTING: Department of Orthopaedics, the 97 Hospital of Chinese PLA. PARTICIPANTS: Totally 100 male recruits aged 18.7 years averagely en rolled in 2003 were involved in the survey. METHODS: The 100 recruits were followed up for the whole course, the X-ray examination at lumbar vertebrae of right, lateral and two-slope positions were observed before training and after 100-day reinforced training. MAIN OUTCOME MEASURES: The incidence rates of spondylolysis of vertebral arch, and whether there was slippage and other aggravations in those with spondylolysis before were mainly observed. RESULTS: All the 100 recruits entered the analysis of results. ① The in cidence rate of spondylolysis of vertebral arch before and after training: Be fore training, 5 cases had spondylolysis of L5 vertebral arch, and the incidence rate was 5%. At the end of the 100-day training, 8 cases had spondylolysis of lumbar vertebral arch, and the incidence rate increased to 8%. ② The results of X-ray examination before and after training: The Xray examination showed that isthmus narrowing of left and L5 vertebral arch occurred in 2 cases and 1 case respect ively, and spondylolysis of bilateral L5 vertebral arches occurred in 5 cases, including 1 case of degree I slip page before training. At the end of the 100-day training, the degree I slip page and below occurred in 3 of the 5 cases with spondylolysis of bilateral L5 vertebral arches before, another 3 cases with original narrowing of lumbar vertebral arch all had breakage. CONCLUSION: The incidence rate of spondylolysis of vertebral arch is associated with the training intensity. It suggestes that the examination of spinal cord should be reinforced in enrolled recruits, and the items of Xray examination at lumbar vertebrae of right, lateral and two-slope positions should be added.
