OBJECTIVE The purpose of this study was to describe the sonographic appearance of the common extensor origin in cadavers and asymptomatic volunteers, and to relate this appearance to the findings in patients with lateral epicondylitis. SUBJECTS AND METHODS Seventy-two elbows in 71 patients with lateral epicondylitis were examined on sonography. Most of(More)
Many standard shoulder outcome measures do not adequately cover the range of problems and issues specifically encountered in glenohumeral joint instability and have been shown not to be sensitive enough to detect clinical change with intervention adequately. The purpose of this report is to present a prospective evaluation of a new self-administered patient(More)
This study describes the MR imaging appearances of the supporting ligaments of the thumb carpometacarpal joint in asymptomatic volunteers and in a group of patients following joint injury. Fourteen patients with 11 acute and three chronic injuries underwent MR imaging. The anterior oblique ligament was the most commonly injured ligament, usually on the(More)
We investigated the association of Dupuytren's contracture with smoking and with alcohol by a case-control study in which 222 patients having an operation for this condition were matched for age, operation date and gender with control patients having other orthopaedic operations. Fifty of the cases were also each matched with four community controls. Data(More)
Ultrasound guidance allows real-time identification of relevant anatomy and needle position when performing brachial plexus regional anaesthesia. The aim of this investigation was to determine whether the use of surface ultrasound could improve the quality of brachial plexus anaesthesia for upper limb surgery. Forty patients were randomized to either(More)
OBJECTIVE The purpose of this study was to describe the MRI appearance of stress reaction in the distal humerus in 12 elite tennis players. In addition, we aimed to determine whether any MRI findings were associated with changes in recovery times. CONCLUSION Stress injury to the distal humerus is a cause of chronic arm pain among elite tennis players and(More)
We describe a safe and simple method of repairing an acute rupture of the distal biceps tendon using a single limited (3 cm) anterior approach, a suture anchor, and the use of a plastic sheath (arthroscopy cannula or barrel of a 2 ml syringe) to protect the adjacent neural structures and to remove the need for extensive dissection and retraction in order to(More)
Upper limb stresses are well recognised in tennis, and the normal physiological responses of the humerus to externally applied forces are well defined. Changes to both the microscopic and macroscopic bony architecture are often not apparent on plain radiographs in the early stages of a stress reaction. Bone scintigraphy is more sensitive, but not very(More)
The sitting upright or 'beachchair' position is commonly used for shoulder arthroscopic surgery. There is a theoretical concern that anaesthetised patients placed in this posture are at risk of reduced cerebral blood flow (CBF), especially if there is associated hypotension. This study investigated the effect of anaesthetic-induced hypotension on estimated(More)
BACKGROUND The upright sitting or beachchair position is associated with hypotension, risk of cerebral hypoperfusion, and cerebral injury. We hypothesized that by increasing arterial pressure with phenylephrine administration, cerebral perfusion, and postoperative recovery would be improved. METHODS Thirty-four patients undergoing elective shoulder(More)
