To determine the factors associated with adherence and persistence to bisphosphonate therapy in osteoporosis. Cross-sectional survey. National survey in the UK. Participants were recruited through the National Osteoporosis Society and advertisements in the press and on the radio and included 533 women over age 50 with osteoporosis who were currently taking(More)
AIMS Femoroacetabular Junction Impingement (FAI) describes abnormalities in the shape of the femoral head-neck junction, or abnormalities in the orientation of the acetabulum. In the short term, FAI can give rise to pain and disability, and in the long-term it significantly increases the risk of developing osteoarthritis. The Femoroacetabular Impingement(More)
BACKGROUND Arthroscopic subacromial decompression (ASAD) is a commonly performed surgical intervention for shoulder pain. The rationale is that removal of a bony acromial spur relieves symptoms by decompressing rotator cuff tendons passing through the subacromial space. However, the efficacy of this procedure is uncertain. The objective of this trial was to(More)
This protocol describes a pragmatic multicentre randomised controlled trial (RCT) to assess the clinical and cost effectiveness of arthroscopic and open surgery in the management of rotator cuff tears. This trial began in 2007 and was modified in 2010, with the removal of a non-operative arm due to high rates of early crossover to surgery. Cite this(More)
The aim of this study was to investigate genetic influences on the development and progression of tears of the rotator cuff. From a group of siblings of patients with a tear of the rotator cuff and of controls studied five years earlier, we determined the prevalence of tears of the rotator cuff with and without associated symptoms using ultrasound and the(More)
BACKGROUND Uncertainty exists regarding the best management of patients with degenerative tears of the rotator cuff. OBJECTIVE To evaluate the clinical effectiveness and cost-effectiveness of arthroscopic and open rotator cuff repair in patients aged ≥ 50 years with degenerative rotator cuff tendon tears. DESIGN Two parallel-group randomised controlled(More)
The Xiao-Kellman catastrophe map, for the classification of classical periodic orbits of the standard 2:1 Fermi resonance Hamiltonian is extended to species with finite vibrational angular momentum. The influence of the classical periodic orbit structure on different organizations of the quantum mechanical eigenvalues, in the four regions of the map, is(More)
BACKGROUND In the majority of patients with osteoarthritis of the knee the disease originates in the medial compartment. There are two fundamentally different approaches to knee replacement for patients with unicompartmental disease: some surgeons feel that it is always best to replace both the knee compartments with a total knee replacement (TKR); whereas(More)
Objectives: This paper evaluates the usefulness of a set of PROMs data collected prospectively, in a relational database, over several years. The data were collected as part of routine practice, to audit patients undergoing shoulder surgery. Methods: Data, rendered anonymous, which included all upper limb surgical procedures and all outcome questionnaires(More)
BACKGROUND Platelet-rich plasma (PRP) is an autologous platelet concentrate. It is prepared by separating the platelet fraction of whole blood from patients and mixing it with an agent to activate the platelets. In a clinical setting, PRP may be reapplied to the patient to improve and hasten the healing of tissue. The therapeutic effect is based on the(More)
