Aims

For rare cases when a tumour infiltrates into the hip joint, extra-articular resection is required to obtain a safe margin. Endoprosthetic reconstruction following tumour resection can effectively ensure local control and improve postoperative function. However, maximizing bone preservation without compromising surgical margin remains a challenge for surgeons due to the complexity of the procedure. The purpose of the current study was to report clinical outcomes of patients who underwent extra-articular resection of the hip joint using a custom-made osteotomy guide and 3D-printed endoprosthesis.

Methods

We reviewed 15 patients over a five-year period (January 2017 to December 2022) who had undergone extra-articular resection of the hip joint due to malignant tumour using a custom-made osteotomy guide and 3D-printed endoprosthesis. Each of the 15 patients had a single lesion, with six originating from the acetabulum side and nine from the proximal femur. All patients had their posterior column preserved according to the surgical plan.

Aims

The aim of this study was to investigate the safety and efficacy of 3D-printed modular prostheses in patients who underwent joint-sparing limb salvage surgery (JSLSS) for malignant femoral diaphyseal bone tumours.

Methods

We retrospectively reviewed 17 patients (13 males and four females) with femoral diaphyseal tumours who underwent JSLSS in our hospital.

Aims

Ilium is the most common site of pelvic Ewing’s sarcoma (ES). Resection of the ilium and iliosacral joint causes pelvic disruption. However, the outcomes of resection and reconstruction are not well described. In this study, we report patients’ outcomes after resection of the ilium and iliosacral ES and reconstruction with a tibial strut allograft.

Methods

Medical files of 43 patients with ilium and iliosacral ES who underwent surgical resection and reconstruction with a tibial strut allograft between January 2010 and October 2021 were reviewed. The lesions were classified into four resection zones: I1, I2, I3, and I4, based on the extent of resection. Functional outcomes, oncological outcomes, and surgical complications for each resection zone were of interest. Functional outcomes were assessed using a Musculoskeletal Tumor Society (MSTS) score and Toronto Extremity Salvage Score (TESS).

Aims

Osseous invasion exhibited in soft-tissue sarcoma (STS) is recognized as a prognostic risk factor. Achieving a wide margin is the default surgical approach for local control. However, for STSs where the tumour is in contact with the adjacent cortex but without clear evidence of osseous invasion, such as medullary invasion, the question of whether bone resection can provide better local control or survival than more conservative sub-periosteal excision remains controversial. The aim of this study was to assess whether bone resection for thigh STS with cortical contact of the adjacent bone results in better local control and survival compared to sub-periosteal dissection, and to investigate the prognostic factors for clinical outcomes in STS.

Methods

A retrospective cohort study was conducted on 142 patients with thigh STS exhibiting cortical contact but without medullary invasion, from May 2000 to May 2020. Patients underwent either composite bone resection or sub-periosteal excision. Demographics, clinical outcomes, and functional outcomes were compared between the two groups. Additionally, Cox regression analysis was used to analyze risk factors for local recurrence.
