Skeletal TB has a paucibacillary nature. It is often found in poorly accessible areas for biopsy purposes. Retrieved samples may have a poor representation of the underlying disease process. Additionally, patients have normally commenced anti-tubercular medication that further decreases the number of bacilli. This has resulted in poor sensitivity and specificity outcomes for the tests that are traditionally done. The polymerase chain reaction (PCR) has been proven to be a useful test for the demonstration of extrapulmonary TB. It has a high specificity and sensitivity. The study measures the sensitivity and specificity of PCR done on fresh biopsies from patients suspected of a tuberculous spinal infection.Introduction:
Objective:
To determine the outcomes of cases converted from an external fixator to an internal fixation device in the management of limb reconstructions and deformity corrections. A retrospective review of 18 patients, that underwent a conversion procedure to internal fixation following long term external fixation use, was done. This comprised 24 limbs. Inclusion criteria: All cases of long term external fixator use converted to internal fixation over a 5 year period. Average external fixation time, pin site care, conversion timing, surgical device used as well as outcome were documented.Purpose of the study:
Method:
Recent literature raised concern on the adverse effects, incidence of pseudo tumours and raised blood and urine Chromium and Cobalt levels in patients with a metal on metal articulation. The purpose of this study was to follow up a cohort of patients that received a metal on metal total hip replacement with minimum follow up of ten years and to compare the results with the literature. All the available patients that underwent metal on metal total hip replacements during 1999 to 2000 with a minimum follow up of 10 years were clinically examined and evaluated with the Harris Hip Score; X-rays; Full Blood Count; CRP; LFT; U, K & E; blood and urine Chromium and Cobalt levels and Ultrasonic examination of the hip. The ultrasound was done by an independent experienced ultrasonographist in each case to exclude pseudo tumours or fluid collections. The patients were clinically examined to try and find any adverse effects of the metal on metal articulation.Purpose of the study:
