The Patient’s Case Presentation The patient had undergone closed reduction and internal fixation for a one-year-old left calcaneum bone fracture. Regretfully, he had persistent osteomyelitis of the calcaneum as a result of an infection at the surgery site. The illness remained after six months of conservative treatment, requiring another course of action.

Line of Treatment Dr. Girish Motwani used a two-phase therapeutic strategy. Read more

To eradicate the osteomyelitis, a complete calcanectomy was done in the initial phase. To manage any leftover infection, bioabsorbable calcium phosphate granules coated with vancomycin were used. For two months, the patient was under close observation to guarantee total wound healing and infection control. In the second phase, a 3D-printed, specially-made calcaneal prosthetic implant was required. Dr Motwani discussed the case with the 3D Incredible team. After it was confirmed that the infection had been eradicated and the soft tissue had healed, the team developed the patient-specific implant. The team used Ti-6-Al-4-V-Eli to create the implant, specifically engineered to match the anatomical structure of the patient. The implant was roughly 68 mm long and 35 mm wide, with a mirror-like surface finish and a lattice structure where it met the bone. Two 6.5mm cancellous screws were used to firmly anchor the implant to the talus. Three 1⁄2 circle suture holes with a 14mm length and profile were also included in the design for soft tissue engagement. For two months following implantation, the patient's foot was immobilized to promote healing and guarantee implant stability. The successful outcome of this case highlights the advantages of patient-specific 3D-printed implants in complex reconstructive surgeries, ensuring improved biomechanics, functional recovery, and long-term stability.Read less
