It is characterized by a tibial anterior bowing deformity or specific types of non-union, which typically result from abnormal development of the tibia, leading to the formation of local pseudarthrosis. The treatment of CPT is very challenging. The advent of 3D printing and computer-assisted techniques in recent years has provided a new ancillary technique for treatment planning and implementation. This case report describes the successful surgical treatment of a 14-year-old male that presented with a shortened limb deformity. Ahead of elective surgery, 3D printing and computer-assisted techniques were used to provide a 1:1 model of his left tibia, fibula and ankle joint to precisely determine the surgical procedure. The first surgery did not result in complete calcification of the tibial extension area, so a second proximal tibia iliac bone graft and internal fixation surgery was undertaken. Following regular follow-up and rehabilitation, by the 18-month follow-up, the proximal tibial bone graft had healed and the patient had resumed walking with a normal gait. This case report describes in detail the successful use of unilateral external fixation using the Ilizarov technique, 3D printing and computer-assisted orthopaedic surgery in the planning of treatment for CPT.<\/jats:p>","DOI":"10.1177\/0300060520945518","type":"journal-article","created":{"date-parts":[[2020,9,25]],"date-time":"2020-09-25T00:46:04Z","timestamp":1600994764000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["A
