Surgical Treatment of Spondylolysis: A Report of 7 Cases / 대한정형외과학회잡지

ABSTRACT

Three main types of operative teehnique are in general use today in the treatment of spondylolysis or spondylolisthesis namely, total laminectomy alone, total laminectomy and posterior fusion, and anterior interbody fusion. According to Hoover(1968), above operations have yielded satisfactory results in approximately 70% of the cases. In recent years, Watkins, Adkins and Rombold have independently reported their cxperience with posterolateral intertransverse fusion, which they claim is based on a more sound mechanical basis and has yielded better results. The author performed anterior interbody fusion in 4 cases and posterolateral intertransverse fusion in 3 cascs at Seoul Naval Hospital during the 2 year period from May 1968 through May 1970 The postoperative follow-up period was maximum one year and minimum six months. Only one casc of anterior interbody fusion has shown sound fusion, while all ihe three posterolateral intertransverse fusions with posterior H-graft have yielded sound fusion with satisfactory clinical improvement by six months after operation.
