Reconstruction after Pelvic Bone Massive Resection: Evolution and Actuality of 3D-Printing Technology.

Purpose Of The Study: Pelvic reconstructions after massive bone resections are among the most challenging practices in orthopedic surgery. Whether the bone gap results after a trauma, a tumor resection, or it is due to a prosthetic revision, it is mandatory to reconstruct pelvic bone continuity and rebuild the functional thread that connects spine and hip joint. Several different approaches have been described in literature through the decades to achieve those goals.

First metatarsophalangeal fusion with dorsal plate: clinical outcomes.

Background: First metatarsophalangeal joint (MTPJ) fusion is the most effective technique for the treatment of MTPJ primary arthritis, severe hallux valgus and failure of primary corrective surgery of these conditions. It can be achieved through different techniques. We evaluated the outcomes in a cohort of patients treated with dorsal plate arthrodesis.

Percutaneous Foot Surgery without Osteosynthesis in Hallux Valgus and Outcomes.

Background: Several procedures and types of osteotomies have been described for hallux valgus (HV) correction. Percutaneous techniques may lead to an early regain of function reducing morbidity and recovery time. In this study, we aimed to evaluate the clinical and radiographic outcomes of percutaneous hallux valgus (HV) correction.

Total hip replacement: a retrospective multicentric analysis on re-intervention rate after single component revision.

Total hip arthroplasty (THA) revision is a procedure consisting in the replacement of a single or multiple implant components and could take place once or more times (re-revision). The aim of this multicentre study is to evaluate the benefits of single component revision in respect of the principles that define implant stability. Two hundred and forty-two patients underwent THA revision at Orthopaedic Clinic of Pisa and Versilia (ITA) from January 2007 to December 2016.

Bone Marrow Concentrate in the Treatment of Aneurysmal Bone Cysts: A Case Series Study.

Introduction: A recent attractive option regarding mesenchymal stem cells (MSC) application is the treatment of bone cystic lesions and in particular aneurysmal bone cysts (ABC), in order to stimulate intrinsic healing. We performed a retrospective evaluation of the results obtained at our institution.

Methods: The study group consisted of 46 cases with an average follow-up of 33 months.
