RESUMO
Three-dimensional (3D) printing technology can generate objects in almost any shape and geometry. This technique also has clinical applications, such as the fabrication of specific devices based on a patient's anatomy. A demonstration study is presented of a 54-year-old man who needed a thermoplastic splint to limit arm movement while a dehisced left shoulder wound healed. The patient's upper extremity was scanned using the appropriate noncontact scanner and 3D technology software, and the polylactic acid splint was printed over the course of 66 hours. This patient-specific splint was worn during the day, and after 2 weeks the wound was healed sufficiently to permit hospital discharge. Creation of an individualized splint is one of many potential medical uses of 3D technology. Although the lengthy printing time imposes limitations, the implications for practice are positive.
