3D printing technology has revolutionized and gradually transformed manufacturing across a broad spectrum of industries, including healthcare. Nowhere is this more apparent than in orthopaedics with many surgeons already incorporating aspects of 3D modelling and virtual procedures into their routine clinical practice. As a more extreme application, patient-specific 3D printed titanium truss cages represent a novel approach for managing the challenge of segmental bone defects. This review illustrates the potential indications of this innovative technique using 3D printed titanium truss cages in conjunction with the Masquelet technique...

INTRODUCTION: In this study, we proposed a three-stage treatment protocol for recalcitrant distal femoral nonunion and aimed to analyze the clinical results. MATERIALS AND METHODS: We retrospective reviewed 12 consecutive patients with recalcitrant distal femoral nonunion undergoing our three-stage treatment protocol from January 2010 to December 2014 in our institute. The three-stage treatment protocol comprised debridement of the nonunion site, lengthening to eliminate leg length discrepancy, deformity correction, stabilization with a locked plate, filling of the defect with cement spacer for inducing membrane formation, and bone reconstruction using a cancellous bone autograft (Masquelet technique) or free vascularized fibular bone graft...

INTRODUCTION: Management of the large gap in long bone fractures is a challenging problem after compound injuries. A novel technique called as Masquelet's technique of "induced membrane formation", is used to bridge a gap of more than 5 cm using bone cement as a spacer in first stage and autologous cancellous bone graft to fill the gap in second stage. CASE PRESENTATION: We present two different and difficult cases with bone defects after open injuries associated with long bone fractures in this paper...

INTRODUCTION: The induced membrane technique (IMT) or Masquelet technique, is a two-step surgical procedure used to treat pseudoarthroses and bony defects. Many authors have introduced variants to the technique. This study aims to compare the surgical variants of IMT and to evaluate its efficacy in achieving infection eradication and bone union. METHODS: A systematic review was carried out following the PRISMA guidelines. PubMed and other medical databases were explored using keywords "Masquelet technique" and "induced membrane technique"...

The induced membrane technique was designed by Masquelet et al. to address segmental bone defects of critical size in adults. It has been used after bone defects of traumatic, infectious and tumoral origin with satisfactory results. Recently, it has been used in children but, after an initial enthusiasm, several cases of failure have been reported. The purpose of this study was to assess the success rate and the risk factors of failure of the induced membrane for children. We conducted a systematic review of all the studies reporting the results of the induced membrane technique to address bone defects of critical size in children...

Reconstruction of large bone defects can be complicated by the presence of both infection and local antibiotic administration. This can be addressed through a two-stage reconstructive approach, called the Masquelet technique, that involves the generation of an induced osteogenic membrane over a temporary poly(methyl methacrylate) (PMMA) space maintainer, followed by definitive reconstruction after the induced membrane is formed. Given that infection and antibiotic delivery each have independent effects on local tissue response, the objective of this study is to evaluate the interaction between local clindamycin release and bacterial contamination with regards to infection prevention and the restoration of pro-osteogenic gene expression in the induced membrane...

BACKGROUND: The treatment of non-unions in long bones poses a great challenge, particularly in cases of infection or large osseous defects. This article evaluates the use of the diamond concept in the treatment of femoral non-unions in a one-step or two-step procedure according to the Masquelet technique. PATIENTS AND METHODS: Between February 2010 and March 2014, 88 patients with atrophic femoral non-unions were included in our study. The treatment was performed in one step (Group G1) on 41 patients and in two-step Masquelet technique (Group G2) on 47 patients, according to the diamond concept...

Posterior Hill-Sachs humeral defects are present in 80% to 100% of cases of anterior shoulder dislocation and are a factor in recurrent instability. Several techniques have been described to fill the defect and avoid recurrence. We developed a percutaneous technique to fill the newly created defect in which a percutaneous balloon, analogous to the one used in vertebral kyphoplasty, is used to reduce the defect, which is then filled with calcium phosphate cement. One patient with an acute anterior dislocation of the shoulder with no previous history was treated using this method...

Pseudoarhtrosis is a relatively frequent complication of fractures, in which the lack of mechanical stability and biological stimuli results in the failure of bone union, most frequently in humerus and tibia. Treatment of recalcitrant pseudoarthrosis relies on the achievement of satisfactory mechanical stability combined with adequate local biology. Herein we present two cases of atrophic pseudoarthrosis that received a Tissue Engineering Product (TEP) composed of autologous Bone Marrow-derived Mesenchymal Stromal Cells (BM-MSC) combined with deantigenised trabecular bone particles from tissue bank...

PURPOSE: Recently we modified the Masquelet technique by using an antibiotic cement-coated locking plate as a temporary internal fixator when treating septic bone defects. This modification is in order to prevent the complications related to external fixator use and provides the involved limb with a greater stability to undergo earlier and more vigorous physical therapy for recovery of joint function. The purpose of this study was to assess the outcomes of large femoral osteomyelitis defects managed by Masquelet technique combined with the antibiotic cement-coated locking plate used as a temporary internal fixator...

The treatment of a large segmental defect of over 6 cm in a long bone is a challenging procedure. Treatment options include cancellous bone graft (e.g., the Masquelet technique), vascularized fibular graft (VFG), and internal bone transport (IBT) with an external fixator. These methods may be performed with intramedullary (IM) nailing or plate fixation to enhance stability or to lessen the time of external fixation. Each method has its own advantages and limitations. This study aimed to describe the advantages of additional plate augmentation and autologous bone grafting after IM nail implantation...

BACKGROUND: The Masquelet technique is a relatively new option in the management of bone defects. It consists of 2-stage surgery. At first surgery, a cement spacer is placed to fill the bone defect. After a waiting period of 6-8 weeks, a pseudo-synovial membrane is formed around the cement. The induced membrane is rich in vascularity and osteogenic activity. At second surgery, the cement is replaced with an autologous bone graft and the graft is packed in the membrane. To harvest large quantities of bone graft, the reamer irrigator aspirator (RIA) is utilized...

BACKGROUND: Gap nonunion of long bones is a challenging problem, due to the limitation of conventional reconstructive techniques more so if associated with infection and soft tissue defect. Treatment options such as autograft with non-vascularized fibula and cancellous bone graft, vascularized bone graft, and bone transportation are highly demanding on the part of surgeons and hospital setups and have many drawbacks. This study aims to analyze the outcome of patients with wide diaphyseal bone gap treated with induced-membrane technique (Masquelet technique)...

In addition to autologous bone graft, vascularized fibular autograft and Ilizarov bone transfer, the Masquelet technique is another effective method to reconstruct bone defects. This technique was initially proposed in 1986 and consists of two stages. At the first stage, radical debridement is required and subsequently, a polymethylmethacrylate (PMMA) cement spacer is implanted at the site of the bone defects. At the second stage, when the PMMA-induced membrane is formed 6-8 weeks later, the cement spacer is carefully removed in order to not disturb the induced membrane and the bone graft is performed to fill the bone defects...
