Biodegradable poly‑L‑lactide‑co‑glycolide copolymer pin fixation of a traumatic patellar osteochondral fragment in an 11‑year‑old child:a novel surgical approach
Abstract
Treating displaced patellar bone fractures in growing children remains a challenge for orthopedic surgeons. Removal of loose bone fragments may prolong healing time and result in early onset osteoarthrosis. Therefore, primary fixation of osteochondral fragments is preferred. Metallic pin and screw implants are typically used for fixation, as there is little evidence available regarding the use of modern biodegradable implants in traumatic patellar fractures of a premature skeleton. The present report describes a novel operative technique using headless poly‑L‑lactide‑co‑glycolide (PLGA) pins in treating an 11‑year‑old girl with a patellar fracture from a cycling injury. The surgical technique of this procedure is described in detail in the current report. Excellent subjective outcomes were achieved from this surgery, with superb bone healing according to follow‑up radiographic and computerized tomography scans. In conclusion, the results of this case indicate that, similarly to osteochondritis, intra‑articular osteochondral fractures in children may be fixed using biodegradable PLGA pins. Randomized clinical trials should be performed to confirm this finding and evaluate the use of PLGA pins as a treatment for adolescent osteochondral fractures
