There is considerable interest in predicting risk of hip fracture in order to allow targeting of preventive care. This study aimed to determine which of two methods best discriminates a hip fracture population from controls. Fifty women with fractured neck of femur, and 50 control subjects were scanned using dual energy X-ray absorptiometry (DXA) of the(More)
This paper compares dual-energy X-ray absorptiometry (DXA) of the spine and hip and broadband ultrasound attenuation (BUA) of the os calcis in 1000 perimenopausal women aged between 45 and 49 years who attended a randomized Osteoporosis Screening Programme. Significant correlations were found between all DXA results and BUA, with the trochanter giving the(More)
STUDY DESIGN The axial length of the vertebral canal and the anterior aspect of the vertebrae were measured in 36 skeletons, 15 with probable idiopathic scoliosis. OBJECTIVES To compare the discrepancy in length of the vertebral canal and the anterior spinal column in skeletons having probable idiopathic scoliosis with the degree of deformity. SUMMARY(More)
Heterotopic ossification developing around the hip and enveloping the sciatic nerve is described in a patient who underwent open reduction and fixation of a large posterior acetabular fragment to decompress and suture the sciatic nerve. The postoperative treatment and a 2-year follow up are also described.
In an attempt to identify a high-risk cohort of patients, who could be offered preventive therapy, we assessed patients who had suffered one hip fracture. A total of 394 patients were prospectively followed to determine those who had suffered a second fracture. Entry bone mass of the unfractured hip and total body was examined by dual X-ray absorptiometry(More)
A 40-year-old male presented with a 2-month history of sudden hearing loss and tinnitus in his left ear. Mild vertigo was present initially but disappeared spontaneously without treatment. Facial nerve paralysis and retroauricular pain appeared 3 months after the onset of hearing loss on the same side. Computerized tomography and magnetic resonance imaging(More)
BACKGROUND cognitive decline is well recognised in Parkinson's disease (PD) but the best cognitive assessment tool for use in such patients remains unclear. The 30-point Mini-Mental State Examination (MMSE), while quick and straightforward to use, fails to cover a full range of cognitive domains and is recognised to have a ceiling effect. The Cambridge(More)
Discs of 20 human lumbar motion segments from donors between 20 and 52 years of age were subjected to a procedure that effected a radial fissure of the anulus, sparing a peripheral layer of approximately 1 mm in thickness. In addition, fragmented tissue pieces that resembled those retrieved at surgery for prolapse were created in the center of the disc. The(More)
Neurogenic claudication is diagnosed from a classical history and complementary spinal imaging. The abnormal signs may be few. It should be distinguished from intermittent claudication (peripheral vascular disease), referred pain from the back or root pain that is aggravated by walking, and psychological distress. Pathologically, a developmentally small(More)
STUDY DESIGN This study involved a model of spinal claudication to assess the effect of single and double site compressions on blood flow in porcine cauda equina. Real-time monitoring of blood flow was achieved by using laser Doppler probes. OBJECTIVES To ascertain the difference between single and double site compressions on blood flow and nerve(More)
