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.

Transphyseal distal humeral separation in neonates: A case series.

Introduction: Birth trauma is a rare condition. Typically, injury in neonates occurs as a result of obstetrical manipulation to allow delivery or from trauma sustained during a difficult passage through the birth canal. Transphyseal separation of the humerus is particularly rare.

Trabecular titanium cups in acetabular revision arthroplasty: analysis of 10-year survivorship, restoration of center of rotation and osteointegration.

Aims: In case of severe bone loss, acetabular revision can be challenged using extra porous pure trabecular titanium (TT) revision cups designed to ensure enhanced iliac and ischiatic purchase. Aim of the study is to report on the clinical and radiological results of a TT acetabular component, evaluating functional outcome, restoration of the hip center of rotation and osteointegration.

Methods: 85 patients, who underwent acetabular revision with a TT revision cup system between October 2009 and December 2018, were included in a retrospective study.

Custom-Made 3D-Printed Implants as Novel Approach to Reconstructive Surgery after Oncologic Resection in Pediatric Patients.

Recently, custom-made 3D-printed prostheses have been introduced for limb salvage surgery in adult patients, but their use has not been described in pediatric patients. A series of 11 pediatric patients (mean age 10.8 years; range 2-13) with skeletal tumors treated with custom-made implants for the reconstruction of bony defects is described.

The challenge of the surgical treatment of paediatric distal radius/ forearm fracture: K wire vs plate fixation - outcomes assessment.

Aim Distal radius/forearm fractures in adolescent patients remain challenging injuries to treat. Distal radius/forearm bony anatomy is not completely restored with intramedullary K wire fixation. The aim of this study was to compare radiographic and functional outcomes obtained using intramedullary K wire fixation and open reduction and internal fixation in the treatment of distal radius/ forearm fracture.

A hollow, custom-made prosthesis combined with a vascularized flap and bone graft for skeletal reconstruction after bone tumour resection.

Purpose: While limb-sparing surgery is now possible for more than 80% of patients with bone tumours, wide resection is often required, necessitating bone reconstruction. This paper aims to present a surgical technique that combines the advantages of a hollow, titanium, custom-made prosthesis and the biological aspects of microsurgical flaps and bone graft.

Patients And Methods: From June 2016 to September 2017 at our institution, six consecutive patients with skeletal tumours underwent one-stage reconstructive surgery with concomitant implantation of a 3D-printed prosthesis.
