We believe that this technique should be considered in pediatric patients with open fractures of the lower limbs and extensive soft tissue injuries.The reimplantation of small or large extruded bone segments is one of the most complex clinical management scenarios in the treatment of open fractures. No consensus exists regarding the efficiency of this technique. The aim of the study was to analyse the clinical and radiological outcomes of Sterilization and Reimplantation Autograft (S.A.R.A.) technique in open fractures. Therefore, fifteen skeletally mature patients with Gustilo-Anderson -IIIB type fractures treated with autograft reimplantation, were included in this study. The sample size was divided in two groups patients with a loss of small segments (Group A – less than 5 cm) and those with large segments (Group B – greater than 5 cm). Eight patients belonged to Group A and seven to Group B. The treatment of contaminated bone may be performed by the following protocols saline rinse, povidone-iodine scrub and saline rinse, retain periosteum, immersion in antibiotic solution (clindamycin and gentamicin and metronidazole), washing with physiological solution, acute reimplantation in Group A or reimplantation after 21 days in Group B after a bone freezing at -80°C. The Radiographic Union Score (RUS), pain visual analogic score (VAS), patient satisfaction and return to work were assessed at a mean follow-up of 24 months. No cases of superficial or deep infection were reported at 2-year follow-up. The fractures achieved a complete union in 14 patients; one patient belonging to Group A had a malabsorption of the replanted bone. Furthermore, povidone-iodine scrub, antibiotic solution immersion, and washing with physiological solution preserved the articular surface morphology. This study suggests that reimplantation of extruded short or long segments may represent a reliable alternative to amputation in open long bone fractures. Further studies are needed to define the most efficient technique for sterilizing the bone autograft to reduce the complication rate.Sickle cell disease causes osteonecrosis (20% to 50% of patients) and collapse of the femoral head that result in secondary osteoarthritis. Total hip arthroplasty (THA) is a valid alternative for these patients. We define the difficulties that can be encountered when undertaking THA in sickle cell disease patients and give advice on how to deal with these technically demanding procedures. We undertook total hip arthroplasty procedures on 12 patients (4 females and 8 males) with osteonecrosis of the femoral head. Two bilateral prostheses were performed. We had only one type of stem, only one type of acetabular cup and only 28 mm cobalt chrome heads. The procedures were performed through either an anterior or a direct lateral approach. The average size of the Cup was 46 (Versafit, Medacta), the average size of the femoral stem was 0 (Amistem, Medacta), the most used size of the modular head was a S. Standard stem that was used in nine patients, while three patients received a lateralizing stem. Three patients had periprosthetic fracture, treated by cerclage. Total hip replacement is an excellent alternative for patients with osteonecrosis from sickle cell disease. The preparation of the acetabulum and the femur is difficult and requires attention, time and appropriate equipment.Distal radius fractures are the most common type of upper limb fractures in adults. Non-union after distal radius fracture is rare, serious and unpredictable. The aim of our paper is to analyse the clinical and radiological outcomes of bone grafting and Sauvé-Kapandji Procedures for the treatment of aseptic distal radius non-union. Pluripotin cell line We enrolled 13 patients with distal radius aseptic non-union. The following parameters were evaluated The surgical time, elbow, forearm and wrist range of motion, the subjective quality of life and the wrist function measured by Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), Pain Visual Analogic Score (VAS) and the complication rate. Bone union was measured using the radiographic union score as described by Radiographic Union Score (RUS). The evaluation endpoint was set at 24 months after surgery. All patients achieved fracture union. Grip strength improved by 12.4 kg. There was also improvement in wrist flexion, in wrist extension, and forearm pronosupination. These ranges of motion and grip strength improvements were statistically significant. Only 6 patients returned to full activity. This surgical technique represents a reliable alternative for treatment of distal radius aseptic non-unions. Further studies are needed to assess the long-term clinical results of this surgical procedure.Non-union in forearm fractures is an uncommon challenging clinical condition for orthopaedic surgeons. The complex anatomy and biomechanics of the upper limb make this surgery very demanding. The accurate restoration of the normal anatomy is mandatory to obtain bone healing. Infections and important bone loss further reduce the therapeutic success. The use of bone graft in atrophic non-union may significantly reduce the bone healing time with good clinical results. The aim of the study was to compare fresh-frozen bone (FFB) allograft and autograft in the treatment of forearm aseptic non-union. Inclusion criteria were patients aged between 18 to 75 years old with forearm aseptic shaft non-union treated with plating and bone grafting. The Authors retrospectively evaluated minimum 12-month follow-up with standard X-rays and clinical outcomes. All non-unions were classified according Association for the Study and Application of the Method of Ilizarov (ASAMI) classification for long bones. The sample size was dividiological outcomes. The study reported a good reliability of FFB allograft for large non-union bone defects. This technique may represent a feasible alternative to bone transport or amputation, as it allows the return to daily life activities. Further studies are needed to assess the long-term clinical results of this surgical procedure.Juvenile osteochondritis dissecans of the knee typically occurs in young athletes, and usually localizes on the medial femoral condyle. Bilateral localization is uncommon. Patellofemoral involvement is rare, mainly found in basketball and soccer players, and never related to patellofemoral congenital problems such as trochlear dysplasia. We report here the first case, to our knowledge, of bilateral juvenile osteochondritis dissecans with patellar localization in a young skier with patellofemoral maltracking and trochlear dysplasia.
