BACKGROUND Displaced fractures of the midpart of the clavicular shaft are generally treated nonoperatively, and few functional deficits have been reported. Whereas prior investigators have presented radiographic and surgeon-based outcomes, we used a patient-based outcome questionnaire and objective muscle-strength testing to evaluate a series of patients(More)
BACKGROUND Under certain conditions it is standard practice to excise ununited humeral condyles during insertion of a semiconstrained total elbow prosthesis. Since the osseous origins of the common extensors and flexor-pronator muscles are lost, it has been postulated that this excision has a negative effect on strength. We are not aware of any previous(More)
The World Health Organization estimates that 10% of the world’s population over the age of 60 suffers from osteoarthritis (OA) [1]. The majority of these cases involve the hip and knee. Symptomatic osteoarthritis of the ankle with radiographic changes is seen in approximately 11% of patients seeking treatment for “arthritis” [1]. Idiopathic arthritis, as(More)
BACKGROUND Popliteal sciatic nerve catheters (PSNCs) are associated with a high frequency of displacement. We aimed to estimate the frequency of catheter displacement after 48 h with magnetic resonance imaging (MRI) in patients with PSNCs after major foot and ankle surgery randomized to catheter insertion either with a short-axis in-plane (SAX-IP) approach(More)
OBJECTIVE To validate a transit time ultrasound flowmeter (CardioMed CM 4000) for measuring blood flow in isolated colonic mesenteric arteries. DESIGN Experimental and clinical study. SETTING Teaching hospital, Denmark. ANIMALS AND SUBJECTS: One female pig, and 6 patients being operated on for carcinoma of the sigmoid colon and rectum. INTERVENTIONS(More)
Background The currently best-established ultrasound-guided lumbar plexus block (LPB) techniques use a paravertebral location of the probe, such as the lumbar ultrasound trident (LUT). However, paravertebral ultrasound scanning can provide inadequate sonographic visibility of the lumbar plexus in some patients. The ultrasound-guided shamrock LPB technique(More)
BACKGROUND Patients with rheumatoid arthritis often have degeneration of the ankle and ipsilateral hindfoot joints. Patients with rheumatoid arthritis undergoing total ankle arthroplasty have a higher risk of wound breakdown and infection. We compared intermediate-term clinical outcomes after total ankle arthroplasty in patients with rheumatoid arthritis(More)
Surgical anaesthesia with haemodynamic stability and opioid-free analgesia in fragile patients can theoretically be provided with lumbosacral plexus blockade. We compared a novel ultrasound-guided suprasacral technique for blockade of the lumbar plexus and the lumbosacral trunk with ultrasound-guided blockade of the lumbar plexus. The objective was to(More)
