Single-stage bilateral total knee arthroplasty is an uncommon and often controversial procedure. Recent reports have refined the data relative to bilateral total knee arthroplasty and complications which include myocardial infarction, deep vein thrombosis, pulmonary embolus and death. Less significant complications, including post-operative ileus and pseudo-obstruction are also more common following bilateral replacement. A retrospective study of the cases of total knee arthroplasty performed by the senior authors in the last ten years, examines details of surgery and anaesthesia, pre and post-operative management to identify the occurrence of complications. Patients also completed an Oxford Knee Score and a questionnaire relating to their experience of having a bilateral procedure. While the outcomes and cost benefits of single stage bilateral replacement are established, the risk of complications remains. This study establishes the low complication rate associated with this procedure in the senior authors’ hands, and documents the high patient satisfaction from it. The study demonstrates that, in selected patients, simultaneous bilateral knee replacement surgery can be performed with good outcomes without a definite increase in perioperative risk.
Introduction: In order to improve the provision of Spinal Surgery in the United Kingdom, the number of Specialist Spinal Surgeons and Surgeons with an Interest in Spinal Surgery needs to increase by 25% from the existing 175 surgeons. There is an expected shortage of Orthopaedic Specialist Registrars (SpRs) planning careers in Spinal Surgery not only to maintain the status quo, with one third of Specialist Spinal Surgeons due to retire in the next three years, but also to provide the needed expansion in numbers. Methods and results: A postal survey of the 528 SpRs was performed with a response rate fo 71%. The critical question was the post accreditation intention as either a Specialist Spinal Surgeon (greater than 70% of elective work), as a Surgeon with an Interest in Spinal Surgery (more than 30% of elective work), a surgeon doing occasional Spinal Surgery (less than 30% of elective work) or one who avoids all Spinal Surgery. This attitude could then be taken into account when analysing the training provided and the perceptions of Spinal Surgery to identify factors which could be discouraging an interest in Spinal Surgery. Sixty-nine per cent indicated that they intended to avoid all Spinal Surgery. Thirty-five (9%) intended becoming either Specialist Spinal Surgeons or Surgeons with a Spinal Interest but only nine (2%) are in their final two years of training. The declared intention to avoid Spinal Surgery increases from 54% in the first two years of training, to 70% in the middle two years, and to 75% in the final two years and post C.C.S.T. fellowships. There should be 24 newly accredited Specialist Spinal Surgeons based on a projection of the 4.3% response intending to become Specialist Spinal Surgeons. This leaves a shortfall of 34 Specialist Spinal Surgeons by 2005. The survey has revealed three main features of Spinal Surgery which appear to have a negative effect on the attitude of the SpRs to Spinal Surgery and overwhelm the potentially attractive features. These are badly organised clinics; the perceived psychological complications of spinal patients; and a perceived inadequate exposure to Spinal Surgery during their training. Conclusion: It is clear from the response of SpRs that there are important misconceptions concerning Spinal Surgery, together with the shortcomings of training and of the provision of services within the NHS. These have to be addressed urgently if the speciality is to become more attractive to them. Areas where positive action can be taken include the modification of training programmes so that all SpRs are exposed to Spinal Surgery in the formative first three years; properly structured spinal clinics; and above all the need for Spinal Surgeons to be encouraging and enthusiastic about a field of surgery which provides some of the exciting challenges in Orthopaedic Surgery.
The relationship between heterotopic bone formation and the morphological type of osteoarthritis was examined after 43 hip replacements. Of the 43 hips studied, nine were atrophic, 19 were normotrophic, and 15 were hypertrophic. The incidence of heterotopic bone formation in the atrophic type was 11%, in the normotrophic type 32%, and in the hypertrophic type 87%. The difference between each type was statistically significant (p less than 0.001).
Seven hips with protrusio acetabuli which showed complete or partial resolution of the protrusion after replacement with Ring's prosthesis are reported. It is suggested that this prosthesis offers a simple and effective method of treating painful protrusion into the pelvis; it allows healing of the medial wall of the acetabulum while avoiding many of the hazards of other methods of treatment.
