“Guidelines issued by the British Association of Plastic Reconstructive and Aesthetic Surgeons suggest that the ratio of elective to emergency cases in plastic surgery units should be 2:1.
To investigate how the workload composition of a regional plastic surgery unit compared with these guidelines.
The changes in
the workload composition of a regional plastic surgery unit were examined by retrospectively analysing all plastic and reconstructive surgery CH5183284 cell line cases performed over 12 years (1998-2009).
This time period saw a change from a 1:2 ratio of elective to trauma procedures, to the recommended ratio, at a time when the overall caseload increased by almost 40 % (3,281 procedures in 1998 to 4,529 procedures in 2009).
Expansion of staff
numbers at consultant and non-consultant grades, and increased resources (allocated theatre sessions and outpatient clinics) were pivotal to this change.”
“Study Design. A retrospective study.
Objective. The purpose of this study are (1) to analyze prevalence of clinical and radiologic EPZ6438 adjacent segment diseases (ASD), (2) to find precipitating factor of clinical ASD in each isthmic and degenerative spondylolisthesis groups, and (3) to compare clinical and radiologic change in isthmic and degenerative spondylolisthesis.
Summary of Background Data. There is no clinical report regarding the use of magnetic resonance imaging (MRI) for evaluating ASD in patient who underwent 360 fusion with single-level spondylolisthesis with healthy adjacent segment.
Methods. selleck chemical A total of 69 patients who underwent instrumented single-level interbody fusion at the L4-L5 level and showed no definitive degenerated disc in adjacent segments
on preoperative MRI and plain radiographs were evaluated at more than 5 years after surgery. The patients were divided into 2 groups: group I was isthmic spondylolisthesis patients and group II was degenerative spondylolisthesis patients. The radiologic ASD was diagnosed by plain radiographs and MRI. Clinical ASD is defined as symptomatic spinal stenosis, intractable back pain, and subsequent sagittal or coronal imbalance with accompanying radiographic changes. Symptomatic spinal stenosis was defined as stenosis diagnosed by MRI and combined with neurologic claudication.
Results. The prevalence of radiologic ASD on group I and group II was 72.7% and 84.0%, respectively. About 7 (15.9%) patients showed clinical ASD in group I and 6 (24.0%) patients showed clinical ASD in group II. MRI showed significant reliability for diagnosis of clinical ASD. Compared with patients with asymptomatic ASD, patients with clinical ASD showed significantly less postoperative lordotic angle at the L4-L5 level (i.e., less than 20) in both groups.
Conclusion.
