Surgical Outcomes in Paediatric Lower Limb Sarcomas: A Single Institutional Experience.

Primary bone sarcomas are rare tumours, comprising approximately 1-2% of adult and around 13-15% of all paediatric cancers. Limb salvage surgery is a challenge in complex musculoskeletal tumours. Young age adds to its complexity, since the growth potential of the reconstruct has to be considered to have optimal function of the salvaged limb.

Biological Prosthesis (Hollow 3D-Printed Titanium Custom-Made Prosthesis and Bone Graft) for Humeral Reconstruction in Pediatric Oncologic Patients: Surgical Indications and Results.

This study presents the mid-term outcomes of a novel "biological prosthesis" for pediatric humerus reconstruction after major bone tumor removal. This approach involves a hollow 3D-printed titanium custom-made prosthesis combined with bone grafting. The primary aim was to preserve and revitalize the unaffected autologous proximal or distal humeral stump.

Long-Term Follow-up in a High-Grade Sarcoma of the Arm Encasing the Radial Nerve Treated by ISP Technique - A Case Report.

Introduction: A combined technique of In situ preparation (ISP) and adjuvant radiotherapy in a case of undifferentiated pleomorphic sarcoma (UPS) encasing the radial nerve was attempted successfully, which can be considered for the preservation of neurovascular structure close to soft-tissue sarcomas for a good functional and oncological outcome.

Case Presentation: A 41-year-old female diagnosed with UPS of the left arm underwent, en bloc excision of the lesion along with the preservation of encased radial nerve using ISP followed by adjuvant radiotherapy. The patient has good functional outcome and a local recurrence free and overall survival of 5 years.

Hemiarthroplasty of Pedicle-Frozen Proximal Tibia for Primary Malignant Bone Tumours.

Unlabelled: The proximal tibia is one of the most common locations for primary malignant bone tumours and is usually seen in a population that has not attained skeletal maturity. Most of the surgical techniques for resection and reconstruction of the proximal tibia in children involves sacrificing the distal femoral epiphysis, which leads to a significant limb length discrepancy. Hemiarthroplasty is a relatively lesser known technique for knee joint reconstruction that preserves one of the epiphyses around the knee joint.
