Tourniquet pressure settings based on limb occlusion pressure determination or arterial occlusion pressure estimation in total knee arthroplasty? A prospective, randomized, double blind trial.

Objective: The aim of this study was to compare the limb occlusion pressure (LOP) determination and arterial occlusion pressure (AOP) estimation methods for tourniquet pressure setting in adult patients undergoing knee arthroplasty under combined spinal-epidural anesthesia.

Methods: Ninety-three patients were randomized into two groups. Pneumatic tourniquet inflation pressures were adjusted based either on LOP determination or AOP estimation in Group 1 (46 patients, 38 female and 8 male; mean age: 67.

Does severe osteoarthritis in knees with varus deformity alter the adductor ratio?

Objective: In our retrospective study, we aimed to investigate the differences between the adductor ratio (AR) in knees with and without osteoarthritis, and its validity in determining the articular level.

Methods: Data from 80 knees of 80 patients were retrospectively evaluated. Anteroposterior weight-bearing knee radiographs of the patients with and without osteoarthritis (40 knees in each group) were obtained.

Clinical utilization of arterial occlusion pressure estimation method in lower limb surgery: effectiveness of tourniquet pressures.

Objective: The effectiveness of the arterial occlusion pressure (AOP) estimation method to set tourniquet inflation pressures was assessed in patients undergoing lower limb surgery.

Methods: One hundred ninety-eight operations were performed in 224 lower extremities of 193 patients. Tourniquet inflation pressures were set using the AOP estimation formula and adding 20 mmHg of safety margin to AOP value.

Practice of tourniquet use in Turkey: a pilot study.

Objective: The aim of the present pilot study was to evaluate patterns in the current practice of tourniquet use in Turkey. The results of this study can provide detailed information regarding tourniquet use and evaluate the need for guidelines on tourniquet use in Turkey.

Methods: The questionnaire was sent to orthopedic residents and surgeons by either giving printed questionnaires directly or by establishing preliminary communication with surgeons and then sending questionnaires by e-mail.

Surgical practices in total knee arthroplasty in Turkey.

Objective: The aim of this study was to determine the current practices in the total knee arthroplasty (TKA) and the differences of practice among the orthopedic surgeons in Turkey.

Methods: Data in this cross-sectional and descriptive study was collected through a questionnaire from 76 orthopaedic surgeons performing TKA. The questionnaire form contained 57 questions under four main headings, covering the professional properties of the surgeon, pre-surgery approach, surgical technique applied for TKA and the surgical details peculiar to the technique with solutions applied for complication scenarios, and finally the postoperative approach.

Os vesalianum pedis.

Os vesalianum pedis is an accessory bone located proximal to the base of the fifth metatarsal. Its prevalence has been reported to be from 0.1% to 1.

[Total dislodgement of the femoral component following cemented total knee arthroplasty: a case report].

Total dislodgement of the components, which is the most severe form of loosening, has hitherto been unreported following total knee arthroplasty. An eighty-four-year-old woman presented with complaints of pain and sensation of insecurity of her right knee after cemented total knee arthroplasty. On physical examination, a clunk was elicited during movements of the knee; however, radiographs appeared normal except for a separated fragment of the medial femoral condyle.

Incomplete scapholunate and trapeziotrapezoid coalitions with an accessory carpal bone.

Coalitions of the carpal bones associated with accessory carpal bones are relatively uncommon. We present a case of scapholunate and trapeziotrapezoid incomplete coalition with a dorsally situated accessory bone between trapezium and trapezoideum. X-ray, computed tomography, and magnetic resonance imaging findings of the patient are discussed in light of the pertinent literature.

Medial approach without opening the joint capsule for developmental dislocation of the hip.

Seventy-one developmentally dislocated hips in 47 children with an average age of 11 months (range 4-16 months) were treated by the medial approach without opening the capsule followed by 6 months of hip spica-cast immobilization. At the latest follow-up 63 hips were rated excellent and good, and 8 hips showed subluxation. No avascular necrosis had occurred.
