This prospective study was undertaken at a regional tertiary referral centre to evaluate the results of treatment of bone defects managed with the induced membrane (IM) technique. Inclusion criteria were patients with bone defects secondary to septic non-union, chronic osteomyelitis and acute fracture with bone loss. Pathological fractures with bone loss were excluded. Data collection included patient...
Mesenchymal stem cells (MSC) from bone marrow and periosteum are known to be heavily involved in fracture repair and bone regeneration is thought to be impaired when the surrounding skeletal muscle is damaged. Recent literature from mouse in vivo models suggest that cells originating from skeletal muscle can occupy a fracture callus during open fracture repair when periosteum is compromised. This...
The management of upper limb non-unions can be challenging and often with unpredictable outcomes. In this study we present our experience with the use of BMP-7 in the treatment of upper limb non-unions. Between 2004 and 2011 all consecutive patients who were treated with BMP-7 were followed up prospectively until fracture union. Fracture union was assessed with regular radiological and clinical assessment...
Chondral and osteochondral lesions represent a debilitating disease. Untreated lesions remain a risk factor for more extensive joint damage. The objective of this clinical study is to evaluate safety and early results of an aragonite-based scaffold used for osteochondral unit repair, by analysing both clinical outcome and MRI results, as well as the benefits of the procedure optimization through novel...
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...
As the tibial bone defect increases in size, the problems in treatment also increase. The treatment may be problematic but different treatment approaches can be used. Among these approaches, distraction osteogenesis is a method an orthopedic surgeon with limited conditions can use although it has a longer treatment period. In our case series, we evaluated current treatment approaches. Retrospective...
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. A systematic review was carried out following the PRISMA guidelines...
The physiopathology of the femoral head bone necrosis is similar for children and for adults. The disease is characterized by apoptosis of bone cells – bone marrow and bone forming cells-resulting in head collapse with a subsequent lesion of the overlying cartilage, and therefore flattening of the rounded surface shape of the head articulating with the acetabulum, provoking, eventually, secondary...
The purpose of this study was to investigate the effectiveness of the chipping technique for the treatment of femoral non-unions associated with malalignment. A total of 21 femoral non-unions were managed with the chipping procedure and re-fixation. 15 of them had malalignment (angular or rotational deformity or limb length discrepancy). The deformities were simultaneously corrected by a combination...
Latest advances made in joint replacement implants allows reconstruction of entire limbs. These special prostheses or megaprostheses were originally designed for the treatment of severe oncological bone loss. Nowadays, however, the indications and applications of these devices are expanding to other orthopaedic and trauma clinical conditions. Since 2008 we have implanted 152 megaprostheses in non-oncological...
