Effect of calf-thigh intermittent pneumatic compression device after total hip arthroplasty: comparative analysis with plantar compression on the effectiveness of reducing thrombogenesis and leg swelling.

The purpose of this study was to evaluate the efficacy of two intermittent pneumatic compression devices as prophylaxis against intravascular coagulation and leg swelling following total hip arthroplasty. We studied 121 patients by assessing thrombogenesis using the D-dimer level before and after total hip arthroplasty. In addition, the patients' postoperative swelling was evaluated by measuring the thigh and lower leg circumference.

Vascular anatomy for rotational acetabular osteotomy: cadaveric study.

Rotational acetabular osteotomies are performed to correct dysplastic hips in young adults. However, there is a potential risk of intrapelvic vascular injury. To define the relation of these vascular structures to the bone around the acetabulum, we measured the distance and direction from the anteroinferior iliac spine to the external iliac artery and from the base of the superior pubic ramus to the obturator artery in 34 cadaveric hemipelves (17 male, 17 female; 19 left, 15 right).

In vivo study of acute effects of hip and knee positions on blood flow in canine sciatic nerve.

We studied blood flow in the canine sciatic nerve using a laser Doppler flowmeter. Blood flow was measured in 20 hind limbs of ten adult dogs at varying angles of hip flexion, hip rotation and knee flexion. Blood flow decreased as flexion and internal rotation of the hip increased and also with only slight flexion of the knee.
