Assessment of Range of Movement, Pain and Disability Following a Whiplash Injury.

BACKGROUND: Whiplash has been suggested to cause chronic symptoms and long term disability. This study was designed to assess long term function after whiplash injury. MATERIAL & METHODS: A random sample of patients in the outpatient clinic was interviewed, questionnaire completed and clinical examination performed. Assessment was made of passive cervical range of movement and Visual Analogue Scale pain scores. One hundred and sixty-four patients were divided into four different groups including patients with no whiplash injury but long-standing neck pain (Group A), previous symptomatic whiplash injury and long-standing neck pain (Group B), previous symptomatic whiplash injury and no neck symptoms (Group C), and a control group of patients with no history of whiplash injury or neck symptoms (Group D). RESULTS: Data was analyzed by performing an Independent samples t-test and ANOVA, with level of significance taken as p<0.05. Comparing the four groups using a one-way ANOVA showed a significant difference between the groups (p<0.001). There were significant differences when comparing mean ranges of movement between Group A and Group D, and between Group B and Group D. There was no significant difference between Group C and Group D. similar differences were also seen in the pain scores. CONCLUSION: We conclude that osteoarthritis in the cervical spine, and whiplash injury with chronic problems cause a significantly decreased cervical range of movement with a higher pain score. Patients with shorter duration of whiplash symptoms appear to do better in the long-term.

The Peri-operative Management of the Rheumatoid Patient Undergoing Total Knee Arthroplasty: A Review of Literature.

Rheumatoid arthritis is the commonest inflammatory arthropathy, and affects synovium, cartilage and bone. Despite recent improvements with disease modifying biological agents, progressive joint destruction may continue eventually leading to the need for joint arthroplasty. The knee joint is involved in 90% of patients with rheumatoid arthritis, and total knee arthroplasty is being performed in many patients to alleviate pain and recover function. However, complications are not uncommon. In this review of the literature we look at pre-operative, intra-operative and post-operative factor that need to be taken into account to reduce the risk of complications in these patients. Due to the systemic nature of rheumatoid arthritis, a multi-disciplinary approach is crucial. This includes addressing medical and pharmacological issues, and anesthetic concerns pre-operatively, and anticipating and preventing relevant complications postoperatively.

Intraoperative nerve monitoring during total shoulder arthroplasty surgery.

BACKGROUND: Nerve injury is an acknowledged complication of total shoulder arthroplasty (TSA). Although the incidence of postoperative neurological deficit has been reported to be between 1% and 16%, the true incidence of nerve damage is considered to be higher. The present study aimed to identify the rate of intraoperative nerve injury during total shoulder arthroplasty and to determine potential risk factors. METHODS: A prospective study of nerve conduction in 21 patients who underwent primary or revision TSA was carried out over a 12-month period. Nerve conduction was monitored by measuring intraoperative sensory evoked potentials (SEP). A significant neurophysiological signal change was defined as either a unilateral or bilateral decrease in SEP signal of ≥50%, a latency increase of ≥10% or a change in waveform morphology, not caused by operative or anaesthetic technique. RESULTS: Seven (33%) patients had a SEP signal change. The only significant risk factor identified for signal change was male sex (odds ratio 15.00, 95% confidence interval). The median nerve was the most affected nerve in the operated arm. All but one signal change returned to normal before completion of the operation and no patient had a persisting postoperative clinical neurological deficit. CONCLUSIONS: The incidence of intraoperative nerve damage may be more common than previously reported. However, the loss of SEP signal is reversible and does not correlate with persisting clinical neurological deficits. The median nerve appears to be most at risk. Monitoring SEPs in the operated limb during TSA may be a valuable tool during TSA.

Perioperative management of chronic respiratory disease.

Respiratory disease contributes significantly to the perioperative challenges of surgery. Preexisting pulmonary co-morbidities and respiratory complications can have profound effects on patient outcomes. Knowledge of these conditions and the potentially deleterious effects of anaesthesia and surgery can enable clinicians to optimise lung function, reduce complications and improve results.

The perioperative management of skeletal metastases.

Bone metastasis is a common problem affecting a significant proportion of patients with metastatic cancer. Bone metastasis can present in a number of ways and the patients may need surgical stabilisation of their lesions. There are many important considerations in the care of these patients that need to be borne in mind including their increased anesthetic risks and potential risk of complications. There are continuous developments in the prevention, diagnosis and treatment with advances in imaging, orthopaedic technique and medication, particularly radiopharmaceuticals and cytotoxic, endocrine treatments with newer treatments based around the tumour cell-osteoclast interaction. Having a better understanding of these considerations and developments is important in allowing the optimisation of the care of the patient with bone metastasis.

Stem cell applications and tissue engineering approaches in surgical practice.

There has been an increasing interest in stem cell applications and tissue engineering approaches in surgical practice to deal with damaged or lost tissue. Although there have been developments in almost all surgical disciplines, the greatest advances are being made in orthopaedics, especially in bone repair. Significant hurdles however remain to be overcome before tissue engineering becomes more routinely used in surgical practice.

Surgical management of fractured neck of femur.

The fractured neck of femur is the classically described fracture in osteoporotic elderly patients. Further, the fracture has a strong predominance in post-menopausal women and, although relatively uncommon in both children and young adults, where present in this age group it is usually the result of significant trauma. In elderly patients, with an already weakened bone, even minimal trauma may be sufficient to cause fracture and as such a fractured neck of femur is often referred to as a fragility fracture.

Surgery for fractured neck of femur - are patients adequately consented?

INTRODUCTION: Obtaining valid consent is a legal and ethical obligation when performing any procedure in clinical practice. This study was performed to identify the validity and effectiveness of the new consent form and any potential improvement that could be made when taking consent. PATIENTS AND METHODS: Case notes of 173 patients undergoing surgery for fractured neck of femur were retrospectively reviewed. Risks and complications of the surgery as listed on the consent form were noted. Sixty-five cases were excluded from the study as they had either old consent forms with no risks recorded or a consent form signed by a consultant due to patient inability to consent. Six of the consent forms could not be located in the notes. This left 102 consent forms to be analysed. RESULTS: The number of risks documented on each form ranged from 0-8 (mean, 3.92). No risks were recorded in 2 of these 102 forms. Most commonly recorded risks were infection (95.1%), DVT/PE (81.4%) and failure of procedure (59.8%). It was shown that many of the consent forms analysed did not have all the serious or frequently occurring risks recorded on them and that a large proportion of the forms had acronyms or phrases that may mean nothing to the patient. Comparison of documented risks for different hip surgery were made using Fisher's exact test showing no significant difference between the risks recorded on the forms for each type of procedure. CONCLUSIONS: Although documentation of risks has been improved compared to old consent forms, patients are not necessarily given the most appropriate information to ensure consent is valid. Further refining of consent forms may be necessary to ensure that all major risks are explained and understood by patients and that there is satisfactory recording of this information.
