Abstract Purpose The purpose of this study was to introduce the surgical technique and functional outcome of joint-sparing limb salvage surgery with metaphyseal osteotomy by dependent design of three-dimensional printed prothesis for children with osteosarcoma in distal femur.Methods Between 2012 to 2019, we performed twelve joint sparing limb salvage surgeries (JSLSS) with metaphyseal osteotomy for the children of osteosarcoma in the distal femur with our dependent design of 3D-printed guided plate and prothesis. The clinical assessment including resection margin, limb-length discrepancy, orthopaedic complications and functional outcome would be analyzed.Results The mean operation time for JSLSS was 107.6 minutes and the average blood loss was 194.5ml with the dependent design of 3D-printed prosthesis. With the assistance of guide plate, the mean margin of the osteosarcoma from the epiphyseal plate was 1.6 cm and the mean limb-length discrepancy was 2.2 cm with maximum follow-up period of seven years (mean 45.3 months, range 12-84 months). All the patients could bend their knee through >90° flexion, achieved similar results for ROMs in 6DOF during gait compared with normal data of Chinese knees, and the mean MSTS score was 94.7 for the patients with JSLSS. One patient had a superficial infection and there was one patient of local recurrence happened during the follow-up with the necrosis rate less than 90% by preoperative chemotherapy. None aseptic loosening happened in distal femur for the patients in this group with dependent design of 3D-printed prosthesis.Conclusion Joint-sparing limb salvage surgery by metaphyseal osteotomy with the dependent design of 3D-printed prosthesis and guide plate would be a good choice for the children with osteosarcoma in distal femur.

In orthopedic oncology, revisional surgery due to mechanical failure or local recurrence is not uncommon following limb salvage surgery using an endoprosthesis. However, due to the lack of clinical experience in limb salvage surgery using 3D-printed custom-made implants, there have been no reports of revision limb salvage surgery using a 3D-printed implant. Herein, we present two cases of representative revision limb salvage surgeries that utilized another 3D-printed custom-made implant while retaining the previous 3D-printed custom-made implant. A 3D-printed connector implant was used to connect the previous 3D-printed implant to the proximal ulna of a 40-year-old man and to the femur of a 69-year-old woman. The connector bodies for the two junctions of the previous implant and the remaining host bone were designed for the most functional position or angle by twisting or tilting. Using the previous 3D-printed implant as a taper, the 3D-printed connector was used to encase the outside of the previous implant. The gap between the previous implant and the new one was subsequently filled with bone cement. For both the upper and lower extremities, the 3D-printed connector showed stable reconstruction and excellent functional outcomes (Musculoskeletal Tumor Society scores of 87% and 100%, respectively) in the short-term follow-up. To retain the previous 3D-printed implant during revision limb salvage surgery, an additional 3D-printed implant may be a feasible surgical option.

Purpose.In all patients treated at the Centre for Bone and Soft Tissue Sarcomas of Aarhus the functional outcome is prospectively evaluated by use of the Enneking system for the functional evaluation after surgical treatment of tumours of the musculoskeletal system. This system has been accepted by the Musculoskeletal Tumour Society and the International Symposium on Limb Salvage.Patients/methods.In the present study the functional outcome after limb-salvage surgery (89 patients) and amputation (58 patients) was compared. In the limb-salvage group the treatment was surgery alone in 50% and surgery combined with either radiotherapy in 39% or chemotherapy in 11%. Inclusion criteria were: Deep seated extremity sarcomas, age >14 years, more than 1 year post-treatment follow-up time and alive at the end of the study. Median age was 49 years (range 14–88 years). Median tumour diameter was 8 cm (range 1–20 cm), median follow-up time was 4.8 years (range 1–11 years). Wilcoxon andχ2-tests were used for statistical analyses.Results.The two groups were comparable according to age, sex, size of tumour, type of tumour, location of tumour, as well as post-treatment follow-up time. The functional scores were significantly higher after limb-salvage surgery as compared to amputation, the median scores being 85 and 47, respectively (p<0.001). A similar difference was observed if the Enneking scores were subdivided into general health-related scores and extremity-related scores. No association was found between functional scores and the following factors by use of univariate analysis: size of tumour, radiation therapy, localization of tumour and surgical margin.Discussion.We conclude that this study indicates that limb-salvage surgery is associated with a better functional outcome than that observed after amputation. However, whether this also indicates a difference in quality of life needs further studies.
