Atraumatic Sacral Fracture in Late Pregnancy: A Case Report.

Study Design Case report. Objective Sacral fractures, traumatic or atraumatic, are a rather rare cause of low back pain. The majority of the cases of pregnancy-related sacral fractures are reported as a postpartum complication, and only few cases of sacral atraumatic fractures have been reported in the last trimester of the pregnancy.

Proximal screws placement in intertrochanteric fractures treated with external fixation: comparison of two different techniques.

Background: To compare two different techniques of proximal pin placement for the treatment of intertrochanteric fractures in elderly patients utilizing the Orthofix Pertrochanteric Fixator.

Methods: Seventy elderly high-risk patients with an average age of 81 years were treated surgically for intertrochanteric fracture, resulting from a low energy trauma. Patients were randomly divided in two groups regarding to the proximal pin placement technique.

Snakebites of fingers or toes by viperidae family members: an orthopaedic approach.

The purpose of this study was to review current principles of therapy for affected patients and determine whether an emergent surgical approach or expectant management should be selected in cases of snakebites of fingers or toes by Viperidae family members. Over the past five years (January 2004 to December 2009), 12 patients bitten by Vipera ammodytes were admitted in our department. We retrospectively reviewed their demographic and epidemiological characteristics as well as their symptoms, laboratory findings, and complications.

Ilizarov treatment of humeral shaft nonunion in an antiepileptic drug patient with uncontrolled generalized tonic-clonic seizure activity.

Nonunion of the humeral shaft in patients with antiepileptic drug associated metabolic bone disorder constitute a challenging surgical problem difficult to treat due to seizure activity, osteoporosis, and poor stabilization options. We report a case of nonunion of the humeral shaft in an antiepileptic drug patient with uncontrolled generalized tonic-clonic seizure activity successfully treated with Ilizarov external fixator and a follow-up of 4 years.

Femoral periprosthetic fracture in osteoporotic bone after a total knee replacement: treatment with Ilizarov external fixation.

We report 3 cases of periprosthetic fractures after total knee replacement treated with Ilizarov external fixator (Smith and Nephew plc, Memphis, Tenn) and a follow-up of at least 3 years. We used 2 rings in the supracondylar area distal to the fracture and 3 half pins proximally in all our cases leaving the knee free to move. In one patient apart from the 2-ring frame placed distal to the fracture site the fixator included another ring frame placed proximally just below the 3 half pins.

Application of the Endomodel rotating hinge knee prosthesis for knee osteoarthritis.

One hundred thirty-six knees were treated with the Endomodel rotating hinge knee prosthesis as primary total knee arthroplasty (TKA). The indications for surgery included osteoarthritis (110 knees), rheumatoid arthritis (18 knees), and osteonecrosis (8 knees). Patients were divided into four study groups according to follow-up duration.

Turret exostosis of the hallux.

A 22-year-old woman presented with pain on the dorsum of her left big toe. The patient had had an accident 1 year previously, when a heavy object fell on her left big toe. She experienced no pain in the hallux before the injury.

Bilateral absence of the patella in nail-patella syndrome: delayed presentation with anterior knee instability.

A 27-year-old man, while serving in the armed forces, presented with complaints of right knee pain of 3 months duration. The patient reported pain localized on the lateral side of the right knee, especially during long-distance walking and stair climbing, and a feeling of giving way. There was no history of recent or remote trauma to the knee joint.

Low-intensity transosseous ultrasound accelerates osteotomy healing in a sheep fracture model.

Background: Low-intensity transcutaneous ultrasound can accelerate and augment the fracture-healing process. The aim of this study was to investigate the effect of transosseous application of low-intensity ultrasound on fracture-healing in an animal model.

Methods: A midshaft osteotomy of the left tibia was performed in forty sheep.

Non-union of femoral neck fractures with osteonecrosis of the femoral head: treatment with combined free vascularized fibular grafting and subtrochanteric valgus osteotomy.

Femoral neck fractures, frequently complicated by non-union and femoral head osteonecrosis,present a difficult clinical situation, especially when young patients are concerned. Existing treatment options are valgus osteotomy to address the biomechanical factors or bone grafting to address the biologic factor. The authors describe the operative technique and results of combined subtrochanteric valgus osteotomy and free vascularized fibular grafting in management of five young patients with both non-union and avascular necrosis.

Posterior tibial subluxation and short-term arthritis resulting from failed posterior cruciate ligament reconstruction.

Posterior tibial subluxations because of combined or isolated posterior cruciate ligament (PCL) injuries require detailed evaluation. PCL reconstructions are difficult procedures because of the low rate of such injuries and the complex anatomy of the ligament. We report on 2 cases of failed PCL reconstruction because of malpositioned femoral tunnels.
