INTRODUCTION Fractures involving bones containing a component of a prosthetic joint are becoming more common. The causation is multifactorial but most of these injuries are associated with trivial trauma. The options available for operative management of these fractures include internal fixation of the fracture alone, fixation of the fracture with revision of the prosthesis, and reconstruction ...

To the best of our knowledge, only 3 cases, including the present case, have been reported with a three part broken pattern. However, this is the first case associated with a distal locking screw broken. We report the case of a 31-year-old patient who sustained an open femoral shaft fracture . The fracture was stabilized with a Kuntcher femoral nail. After 7 months of the initial surgery he pre...

We describe two carnivoran coprolites found in the pseudokarst natural carnivore trap of Batallones-3, from Late Miocene Spain. The larger one, comprising multiple indistinguishable fragments broken and corroded bones, indicates that producer dropping might have been highly capable crushing softer parts large bones. On other hand, smaller one shows several relatively more complete bone fragment...

The nasal bone is among the most frequently broken facial bone due to all types of trauma and is the most frequently fractured facial bone due to motor vehicle collisions. This study reports the results of anterior-posterior impacts performed on male cadavers using a free-falling impactor with a flat impacting surface. The force at fracture onset was determined using an acoustic emission sensor...

arm grooves of star-fish have mesenchymal stem cells derived from adipose tissue cell. widespread studies have shown that stem cells derived from adipose-derived mesenchymal stem cell from bone marrow have many similarities in terms of the ability to differentiate into a variety of tissues. most of the animals live in warm and shallow waters and the waters of this feature is that it is low in d...

two experiments were conducted to determine lysine (lys) requirements of two commercial strains, ross 308 and cobb 500, from 15 to 28d of age. basal diet was formulated to be adequate in all nutrients except for lys. incremental levels of supplemental lys were added to the basal diet generating six experimental treatments in a range from 0.60 to 1.20% digestible lys. birds were randomized acros...

A 43-year-old drug addicted female was referred for a L5-S1 posterolateral in situ fixation with autologous graft because of an L5/S1 severe discopathy with listhesis. After six months, low back pain recurred. A Tc-99m HDP SPECT-CT diagnosed a pseudarthrosis with intense uptake of the L5-S1 endplates and a fracture of the right S1 screw just outside the metal-bone interface without any uptake o...

The management of diabetic neuropathic foot and ankle malunions and/or nonunions is often complicated by the presence of broken or loosened hardware, Charcot joints, infection, osteomyelitis, avascular bone necrosis, unstable deformities, bone loss, disuse and pathologic osteopenia, and ulcerations. The author discusses a rational approach to functional limb salvage with various surgical techni...

UNLABELLED The introduction of locking plate devices have increased the number of viable options for fracture fixation. An understanding of the indications and contraindications and technique limitations are important to minimise associated adverse events. We report the case of a patient who presented with a single broken screw head four years following fixation of a supracondylar femur fractur...
