Case ReportsBilateral non-traumatic acetabular and femoral neck fractures due to pregnancy-associated osteoporosis.
Pregnancy-associated osteoporosis is a rare disorder and its pathophysiology remains unknown. We report a case of pregnancy-associated osteoporosis in a 27-year-old primiparous patient who revealed bilateral hip pain during early postnatal period. The plain radiographs and computerized tomography showed bilateral femoral neck and acetabular fractures. ⋯ The case was treated successfully by bilateral cementless total hip arthroplasty. Bone mineral density increased after 2 years of treatment with calcium-vitamin D, calcitriol and alendronate. Diagnosis of pregnancy-associated osteoporosis should be suspected when hip pain occurs during pregnancy or in the post-partum period as it can lead to acetabular and femoral neck fractures.

A new tourniquet system that determines pressures in synchrony with systolic blood pressure.
This study reports the results of the clinical use of a new tourniquet system for surgery of the lower extremity that can determine tourniquet pressure in synchrony with systolic blood pressure. ⋯ The conventional tourniquet pressure in the lower extremity is 300 or 350 mmHg, whereas this synchronized system required less pressure, making it a safe, useful device for controlling a bloodless surgical field in lower extremity surgery.

Case ReportsExtreme complications of Fixion nail in treatment of long bone fractures.
The authors present their experience related to extreme complications in treatment of diaphyseal fractures of the long bones with application of the Fixion expansion intramedullary nail in a total of 48 surgeries. We have encountered six (12.5%) extreme complications in the management of fractures of 3 humeral, 2 tibial, and 1 femoral bones during its application procedure and postoperative follow-up. Of six cases, two with humeral and tibial fractures developed nonunion and rotational instability because of failure of inflation of the Fixion nail. ⋯ Application may need special training. Since the Fixion has not got rotational stability and rigidity as conventional nailing systems, bending and breaking of the nail may occur during postoperative period in patients with over obesity and hyperactivity. In patients with osteogenesis imperfecta, it may not be the first choice as a nailing system.
