ABSTRACT BACKGROUND: Children with osteogenesis imperfecta suffer from frequent fractures and deformities due to skeletal fragility. Stabilisation of fractures, correction deformity intramedullary rodding result in decreased pain improved function. Modern expandable rods aim provide lasting stability during growth, without an increase complications. The our study was determine compare the outco...

in iran, onion plants are currently broadcast over the majority of onion fields and weeding and harvesting are done manually by seasonal workers. at harvest time, 40 worker-days are required to onion dig just one hectare. this cost could be saved if the operation could be carried out by machine. rear-mounted diggers can only be implemented if 40 cm spacing between rows is allowed for each tract...

Background. The reconstruction of femoral shaft defects after tumor resection involves joining healthy bone fragments with plates or intramedullary rods, using methyl metacrylate cement or bone grafts. Material and methods. 50 patients (35 females and 15 males) were operated over the last 24 years. The patients' ages ranged from 12 to 80 years (mean 56). Results. There were 37 bone metastases, ...

Internal fixation is a widely used treatment method to repair bone fracture, which is one of the most common orthopedic trauma. However, in reaming of the intramedullary canal to facilitate insertion of a guiding rod by creating a surgical passage, severe disturbances such as increased local cortical temperature and elevation of intramedullary pressure can occur. These disturbances have resulte...

BACKGROUND AND PURPOSE The PRECICE intramedullary limb lengthening system uses a new technique with a magnetic rod and a motorized external remote controller (ERC) with rotational magnetic field. We evaluated the reliability and safety of the PRECICE system. METHODS We compared our preliminary results with PRECICE in 24 patients (26 nails) with the known difficulties in the use of mechanical ...

BACKGROUND Reamed interlocking intramedullary nailing is considered the gold standard treatment for complex fractures of the femoral and tibial shaft. There has been some controversies about dynamization of statically locked nails, and some authors recommended routine dynamization for promotion of healing. This study aims to evaluate treatment of complex fractures in tibia and femur with static...

The treatment of osteoporotic long bone fractures is difficult due to diminished bone density and compromised biomechanical integrity. The majority of osteoporotic long bone fractures occur in the metaphyseal region, which poses additional problems for surgical repair due to increased intramedullary volume. Treatment with internal fixation using intramedullary nails or plating is associated wit...

BACKGROUND Lower limb loss is a highly disabling medical condition that can severely impact a person's quality of life. Recovery becomes especially challenging if an amputee has a short residual limb, which can complicate proper prosthetic fitting, causing discomfort, difficulties in suspension, and reduced mobility. Current limb lengthening techniques such as the Ilizarov apparatus and externa...
