INTRODUCTION: Restoration of the physiological biomechanical principles of the hip is crucial in total hip replacement. The aim of this study was to compare an arthroplasty system with different offset options (a: Exeter(®)) with a dual-modular stem (b: Profemur Xm(®)). MATERIALS AND METHODS: A local and an inertial coordinate system were used to assist the description of the components' assembly in the prosthesis. A resection line of the femoral head in standard position was added to the arthroplasties and geometric parameters were measured...

The acetabular labrum of the hip (ALH) is recognized as a clinically important structure, but knowledge about the pathophysiology of this fibrocartilage is scarce. In this prospective study we determined the prevalence of ALH calcification in patients with end-stage osteoarthritis (OA) and analyzed the relationship of cartilage calcification (CC) with hip pain and clinical function. Cohort of 80 patients (70.2±7.6years) with primary OA scheduled for total hip replacement. Harris Hip Score (HHS) was recorded preoperatively...

BACKGROUND: Invasive ventilation is used to assist or replace breathing when a person is unable to breathe adequately on their own. Because the upper airway is bypassed during mechanical ventilation, the respiratory system is no longer able to warm and moisten inhaled gases, potentially causing additional breathing problems in people who already require assisted breathing. To prevent these problems, gases are artificially warmed and humidified. There are two main forms of humidification, heat and moisture exchangers (HME) or heated humidifiers (HH)...

Hypothenar hammer syndrome (HHS) is an uncommon cause of unilateral Raynaud's phenomenon, splinter haemorrhages and hypothenar weakness. The typical patient is a male blue-collar worker who uses their hypothenar eminence to hammer objects as part of their work. The distal ulnar artery beyond Guyon's canal is superficial and vulnerable to blunt trauma. CTA and MRA are common initial investigations and can suggest the diagnosis. DSA is the gold standard imaging modality and offers therapeutic opportunities. Management is controversial, but unless there is critical digital ischaemia, conservative treatment is first line...

BACKGROUND: Osteonecrosis of the femoral head (ONFH) often affects young active adults and leads to destruction of the hip joint and disabling arthritis. Several procedures have been developed to arrest the progress of osteonecrosis and postpone the procedure of total hip replacement especially in young patients. The aim of this multicenter study was to analyze the results of the use of the vascularized iliac bone flap transfer for management of ONFH. METHODS: From January 1985 to December 2012, a total of 2190 patients (2690 hips) with the mean age of 43...
