Vascularized bone grafts have been successfully established for complex bone defects. The integration of three-dimensional (3D) simulation and printing technology may aid in more precise surgical planning and intraoperative bone shaping. The purpose of the present study was to describe the implementation and surgical application of this innovative technology for bone reconstruction.

Article Synopsis
- - Congenital pseudoarthrosis is a rare bone disorder primarily affecting the radius, ulna, tibia, and fibula, with a few cases reported in association with conditions like neurofibromatosis and fibrous dysplasia, while acquired cases often follow fractures or infections like tuberculosis.
- - A 3-year-old girl presented with pain and swelling in her right thigh, where an MRI indicated chronic osteomyelitis with non-united fracture, leading to abnormal mobility and cortical resorption.
- - The treatment involved surgical resection of the pseudoarthrosis followed by a two-stage masquelet procedure, which included bone grafting and plate fixation to support healing.
Effective treatment of scaphoid pseudoarthrosis is critical to reduce the risk of progression to the potentially debilitating scaphoid nonunion advanced collapse, including complications of persistent wrist joint instability, degenerative arthritis, decreased range of motion, chronic pain, and functional impairment. Both anatomic and fracture-related pathophysiology predispose patients to scaphoid nonunion, including limited retrograde blood flow, fracture location, and delay of appropriate treatment. Recent studies have demonstrated successful outcomes in treatment of scaphoid nonunions, with nonvascularized bone autograft, commonly from distal radius or iliac crest, as well as pedicled vascularized or free vascularized autograft with rates of union varying from 84% to 100%.

Forearm non-union poses a challenge in orthopaedic surgery due to its intricate anatomy and functional significance. This review provides a comprehensive overview of the assessment, diagnosis and management of forearm non-union. Initial evaluation involves a meticulous history, physical examination and imaging studies to identify factors contributing to non-union, including infection.

Congenital pseudarthrosis of the forearm bones (CPFBs) is rare, with only 106 reported cases, and is frequently associated with neurofibromatosis (NF). Approximately 5% of patients with NF develop pseudarthrosis, and 50% of patients with pseudarthrosis have NF. Achieving bone union is difficult in congenital pseudarthrosis.
