“…Establishing the best surgical option in treating musculoskeletal neoplastic and non-neoplastic conditions is ongoing. [17][18][19][20][21][22][23] Our comparison of rAPC reconstruction with osteoarticular allograft reconstruction in treating distal femoral tumours in children revealed knee stability and functional outcomes were statistically significantly better in the rAPC group, while the ROM in the knee was statistically significantly better in the osteoarticular allograft group. These findings were clinically relevant.…”

Aims Osteoarticular reconstruction of the distal femur in childhood has the advantage of preserving the tibial physis. However, due to the small size of the distal femur, matching the host bone with an osteoarticular allograft is challenging. In this study, we compared the outcomes and complications of a resurfaced allograft-prosthesis composite (rAPC) with those of an osteoarticular allograft to reconstruct the distal femur in children. Methods A retrospective analysis of 33 skeletally immature children with a malignant tumour of the distal femur, who underwent resection and reconstruction with a rAPC (n = 15) or osteoarticular allograft (n = 18), was conducted. The median age of the patients was ten years (interquartile range (IQR) 9 to 11) in the osteoarticular allograft group and nine years (IQR 8 to 10) in the rAPC group (p = 0.781). The median follow-up of the patients was seven years (IQR 4 to 8) in the osteoarticular allograft group and six years (IQR 3 to 7) in the rAPC group (p = 0.483). Limb function was evaluated using the Musculoskeletal Tumor Society (MSTS) score. Results At final follow-up, the knee was unstable in 9/18 patients (50%) in the osteoarticular allograft group and 2/15 patients (13%) in the rAPC group (p = 0.026). The median range of motion (ROM) of the knee was 117° (IQR 115° to 120°) in the osteoarticular allograft group and 100° (IQR 95° to 105°) in the rAPC group (p < 0.001). The median MSTS score was 25 (IQR 23 to 26) in the osteoarticular allograft group and 28 (IQR 26 to 29) in the rAPC group (p = 0.007). Osteoarthritic change was detected in 11/18 patients (61%) in the osteoarticular allograft group and in 4/15 (26%) patients in the rAPC group (p = 0.048). Conclusion In our series, a resurfaced allograft-prosthesis composite provided better knee stability and function, with a lower rate of osteoarthritis; an osteoarticular allograft was associated with better knee ROM.

“…ABCs are benign bone tumor-like lesions with unknown etiology and are highly invasive and destructive [ 10 ]. First reported by Jaffe et al [ 11 ] in 1942, ABCs account for approximately 1% of bone tumors, which are mainly concentrated in the long bones of the extremities and spine, while cases occurring in irregular bones such as the scapula are rare [ 10 , 12 ]. Although ABCs are benign, they often exhibit invasive behavior and a tendency to relapse.…”

Background The irregular anatomical shape and complex structures of irregular bones make it more difficult to repair and reconstruct bone defects in irregular bones than in the long bones of the extremities. Three-dimensional (3D) printing technology can help to overcome the technical limitations of irregular bone repair by generating simulations that enable structural integration of the lesion area and bone structure of the donor site in all directions and at multiple angles. Thus, personalized and accurate treatment plans for restoring anatomical structure, muscle attachment points, and maximal function can be made. The present study aimed to investigate the ability of 3D printing technology to assist in the repair and reconstruction of scapular aneurysmal ABC defects. Methods The study included seven patients with ABCs of the scapula. Based on computed tomography (CT) data for the patient, the scapula (including the defect) and pelvis were reconstructed using Mimics Medical software. The reconstructed scapula model was printed using a 3D printer. Before the operation, the model was used to design the surgical approach and simulate the operation process, to determine the length and radius of the plate and the number and direction of screws, and to determine the bone mass of the ilium and develop reasonable strategies for segmentation and distribution. The operation time, amount of bleeding, length and radius of the plate, and direction and number of screws were recorded. Results The average duration of follow-up was 25.6 months, and none of the seven patients experienced recurrence during the follow-up period. The surgical approach, the length and radius of internal fixation, and the number and direction of screws were consistent with the designed operation plan. Patients gradually recovered the anatomical structure of the scapula and function of the shoulder joint. Conclusions In the treatment of bone defects caused by irregular bone tumors, 3D printing technology combined with surgery has the advantages of less trauma, short operation time, less bleeding and reducing the difficulty of operation, which can reduce the waste of bone graft, and more complete reconstruction of the anatomical structure of the defective bone.

“…Its rst discovery was reported by Jaffe and Lichtenstei et al [10] in 1942. The incidence of ABC accounts for about 1% of bone tumors, which are mainly concentrated in the long bones of extremities and spine, while irregular bones such as scapula are rare [9,11]. Although ABC is a benign bone tumor, its biological behavior is often invasive and easy to relapse.…”

“…Its invasive and recurrent characteristics often lead to more serious bone destruction, and severe cases can be associated with pathological fractures, which brings some di culties to treatment [12]. The treatment of aneurysmal bone cysts that occur in irregular bones is more challenging, and the repair and reconstruction of bone defects are also more di cult [11].…”

Objective: To explore the clinical efficacy of using 3D printing individualized treatment plan in the auxiliary repair and reconstruction of irregular bone tumor bone defect.Methods：Seven patients with aneurysmal bone cyst of scapula were selected. Based on the CT data of the patient, the scapula (including defect) and pelvis were reconstructed by computer Mimics Medical software. Print out the reconstructed scapula model with a 3D printer. Before operation, the model was used to design the surgical approach and simulate the operation process, to determine the length and Radian of the plate and the number and direction of screws, and to determine the bone mass of the ilium and make reasonable segmentation and distribution. The operation time, the amount of bleeding, the length and Radian of the plate, and the direction and number of screws were recorded.Results : The average follow-up time was 25.6 months, and none of the 7 patients had recurrence during the follow-up period; The surgical approach, the length and Radian of the internal fixation, the number and direction of screws were consistent with the designed operation plan. The anatomical structure of scapula and the function of shoulder joint gradually recovered.Conclusions: Compared with traditional methods, the use of 3D printing technology in the treatment of irregular bone tumor bone defect has less trauma, shorter operation time and less bleeding, which can reduce the waste of bone graft and reconstruct the anatomical structure of bone defect more completely.
