The Direct Repair of Unilateral Spondylolysis with the Guidance Aid of a Personalised Rapid Prototping Template

5 pagesPublished: June 13, 2017


The reported incidence of spondylolysis in athletes varies between 15% and 47%, considerably more than 6% in the general population, with most common types of related sport activities being gymnastics, weight lifting, soccer, swimming, cricket and tennis. (Reitman, Stanitski). The repeated tension stress microtrauma on the ventro-caudal part of the inferior articular facet during lumbar hyperextension and trunk twisting movements, together with anatomical predispositions can result in complete symptomatic fracture defect, preventing further participation in sports activities. Although less common and more benign, unilateral isthmic stress fractures tend to be resistant to conservative management if not properly addressed initially, therefore warranting early operative treatment (Debnath).
