Clinical, radiological and surgical studies have been made of 57 farmers who were operated upon for degenerative lumbar canal stenosis (Group A) and degenerative spondylolisthesis (Group B). The improvement rate was excellent in both groups.(Group A: 75.6%, Group B: 71.7%). The improvement rate in abdominal and back muscle strength was lower in cases with postoperative kyphosis than in those with postoperative lordosis. Cases with a slip angle of less than 0 degrees postoperatively showed less improvement and a lower abdomminal and back muscle strength than those with an angle of 0 degrees or more. Disappearance of lumbar lordosis, local kyphotic alignment, low strength of abdominal and back muscles are unfavourable factors influencing return to farm work.
