Fresh Osteochondral Allograft in a Complex Hoffa Fracture - Case Report.

Hoffa fracture (HF) typically involves the posterior femoral condyle in the sagittal plane, with an estimated incidence of 0.65% among femoral fractures. It usually occurs at the lateral femoral condyle in high-energy trauma with axial load force over the distal third of the femur and the knee positioned in more than 90° of flexion.

PTH improves devitalized allogenic bone graft healing in a murine femoral critical size defect.

The treatment of large segmental defects of long bones resulting from trauma, infection, or bone tumor resections is a major challenge for orthopedic surgeons. The reconstruction of bone defects with acellular allografts can be used as an osteoconductive approach. However, devitalized allografts are associated with high rates of clinical failure as a result of poor intrinsic osteoinduction properties and a lack of further remodeling.

The effect of autologous concentrated bone-marrow grafting on the healing of femoral shaft non-unions after locked intramedullary nailing.

The aim of this study was to assess the union rates in a series of patients with failed femoral shaft aseptic non-union who were treated with percutaneous concentrated autologous bone marrow grafting. Bone marrow harvesting and cell injection were performed under general anaesthesia in a single surgical procedure. Radiographic union was diagnosed in fractures with a score ≥ 10 according to the radiographic union scale in tibial fractures (RUST) and confirmed by clinical examination.

Surgical treatment for unstable pelvic fractures in skeletally immature patients.

Objective: To present the results and conclusions of our study on surgical treatment for unstable pelvic fractures in children subjected to surgical reduction and stabilisation.

Methods: We analysed the cases of fourteen skeletally immature patients with unstable pelvic fractures who underwent surgery for this condition between March 2004 and January 2011. The surgical technique used was based on the principle of surgical reduction and stabilisation of anterior and posterior lesions of the pelvic ring.

SURGICAL TREATMENT OF UNSTABLE PELVIC RING FRACTURE IN SKELETALLY IMMATURE PATIENTS.

Objectives: To present the outcomes from definitive surgical treatment for unstable fractures of the pelvic ring in children undergoing surgical reduction and stabilization.

Methods: We studied 10 patients with immature skeletons who suffered unstable fractures of the pelvic ring and were treated between March 2004 and January 2008. The study was retrospective, based on clinical and radiographic evaluations.

EPIDEMIOLOGY OF ACETABULUM FRACTURES TREATED AT THE INSTITUTO NACIONAL DE TRAUMATOLOGIA E ORTOPEDIA (INTO).

Objectives: The purpose of this study was to review the epidemiological aspects of displacement fractures of the acetabulum that had been treated surgically at the National Institute of Traumatology and Orthopedics (INTO).

Methods: We retrospectively analyzed 126 acetabulum fractures that had been treated surgically at INTO between March 2006 and November 2008. The following factors were taken into account: age, sex, trauma mechanism, injury classification, time elapsed between trauma and surgery, affected side and associated bone injuries.

Use of noninvasive positive pressure ventilation and spinal anesthesia during hip replacement arthroplasty in a patient with severe chronic obstructive pulmonary disease: case report.

Anesthetic management of patients with severe chronic obstructive pulmonary disease is extensively discussed, due to the high rates of complications in this subtype of patients submitted to medium and high complexity surgical procedures. The objective of this study is to report use of noninvasive positive pressure mechanical ventilation - bilevel positive airway pressure - and spinal anesthesia in a patient with severe chronic obstructive pulmonary disease during total hip arthroplasty. An 81 year old, male patient with severe chronic obstructive pulmonary disease (GOLD 4) was submitted to total hip arthroplasty due to a femoral bone fracture under spinal anestesia and noninvasive positive pressure mechanical ventilation-bilevel positive airway pressure with expiratory pressure of 7 cmH2O, inspiratory pressure of 15 cmH2O and O2 flow of 3 L/min.
