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...

Perilunate fracture-dislocation is rare. We report the case of a 24-year-old male who fell from his motorcycle and presented with a transverse lunate fracture with perilunate ligament damage. The initial diagnosis based on X-rays was confirmed by CT scan. A dorsal approach was used to obtain good reduction, double screw fixation and ligament reinsertion protected by temporary K-wires. To the best of our knowledge, this is the first case of transverse lunate fracture within perilunate fracture-dislocation. The patient returned to normal activities after 6 months...

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...

BACKGROUND: The treatment of non-unions with large bone defects or osteitis is a major challenge in orthopedic and trauma surgery. A new concept of therapy is a two-step procedure: Masquelet technique according to the diamond concept. METHODS: Between February 2010 and June 2014, 55 patients with tibia non-unions or infections were treated in a two-step Masquelet technique in our center. The patients' average age was 48 (median 50; minimum 15-maximum 72) with an average BMI (body mass index) of 28 (27; 18-52)...

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)...

This study was a retrospective evaluation of 18 patients with traumatic bone loss affecting the fingers, hand and wrist who were treated using the induced-membrane technique. Sixteen men and two women, mean age 54years (27-74) presented a hand injury including bone loss. Sixteen patients were treated on an emergency basis and two following nonunion of their fractures. There were 13 cases of open fracture of the phalanx and 5 cases of metacarpal fractures. These patients were treated with debridement and the injuries were covered when necessary...

François Humbert (1776-1850) created in 1817 the first French orthopaedic institution, at a great turning point in orthopedics. Interested in "lame people" and "hunchbacks", he treated congenital hip dislocation and scoliosis, for about 30 years. Humbert's medical practice illustrated very well the deep transformation which occured in orthopedics at the beginning of the 19th century. As testimonies of Humbert's work, there are the books he published, his Memoirs, some buildings of his institution which have been reconverted into houses, but above all thirty-eight models of his "machines"...

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...

Critical-sized bone defects present a significant burden to the medical community due to their challenging treatment. However, a successful limb-salvaging technique, the Masquelet Technique (MT), has significantly improved the prognosis of many segmental bone defects in helping to restore form and function. Although the Masquelet Technique has proven to be clinically effective, the physiology of the healing it induces is not well understood. Multiple modifiable factors have been implicated by various surgical and research teams, but no single factor has been proven to be critical to the success of the Masquelet Technique...

BACKGROUND: Surgical reconstruction of segmental skeletal defects represents a true challenge for the orthopedic surgeons. Recently, Masquelet et al. described a two-stage technique for reconstruction of bone defects, known as the induced membrane technique. The aim of this study is to assess the results of the induced membrane technique in the management of segmental skeletal defects resulting from debridement of bone infection. MATERIALS AND METHODS: Seventeen patients with segmental skeletal defects were treated in our institution by the induced membrane technique...

INTRODUCTION: Biochemical processes during bone regeneration can be analysed via quantification of peripheral serum cytokine levels. To date, serum levels of cytokines in patients treated with masquelet technique and patients with normal bone healing have not been compared. This comparison is supposed to deliver novel insights into the process of bone regeneration. Our aim was to validate this established method in the monitoring of bone regeneration after non-union treatment in masquelet technique...

REVIEW
R Gouron
The induced membrane technique is now quite adaptable to segmental bone reconstruction in children. This technique is much the same as the technique used in adults. A cement spacer is interposed, and in a second operating phase, occurring 6 weeks after the interposition of the spacer, the cement is removed and a morselized corticocancellous graft is installed in the induced membrane that had formed around the cement. Graft expansion using allograft chips should not exceed 30% of the total volume. An additional autograft strut is useful in the reconstruction of long femoral or metaphyseal-diaphyseal tibial defects...
