Inclusion criteria
Inclusion criteria: 1) Pediatric and adolescent patients between 7 and 18 years of age with extensive resection due to malignant bone tumor.
Exclusion criteria
Exclusion criteria: 1) Insufficient suturing of soft tissue 2) If there are signs of infection at the time of surgery 3) If life expectancy is less than 3 months 4) Except for studies using metal printing when conventional artificial joint substitutes can be sufficiently treated. 6) If you have an immune disease including acquired immunodeficiency disease
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| After checking the error with the planned resection margin in the resection using 3D printing, comparing the size of the resection margin set from the surgical tumor with the size of the resection margin confirmed in the pathological biopsy after resection, the resection status after surgery was evaluated through CT. The extent of resection is compared with the resection margin planned through image reconstruction. | — |
Secondary
| Measure | Time frame |
|---|---|
| Primary cancer-related: Primary cancer type, treatment type, period;Stage-related: presence of metastasis to other organs and treatment history;Functional results: Confirmed through resection margin evaluation, MRI, CT combined evaluation, type of resection guide, functional results and joint range of motion evaluation on outpatient observation after surgical treatment, and check for complications related to treatment. | — |
