Distinction between foot and ankle wound healing complications as opposed to infection is crucial for appropriate allocation of antibiotic therapy. Our aim was to evaluate the diagnostic accuracy of white cell count (WCC) and C-reactive protein (CRP) as diagnostic tools for this distinction in the non-diabetic cohort. Data were reviewed from a prospectively maintained Infectious Diseases Unit database of 216 patients admitted at Leicester University Hospitals – United Kingdom between July 2014 and February 2020 (68 months). All diabetic patients were excluded. For the infected non-diabetic included patients, we retrospectively retrieved the inflammatory markers (WCCs and CRP) at the time of presentation. Values of CRP 0–10 mg/L and WCC 4.0–11.0 ×109 /L were considered normal.Abstract
Background
Methods
Flexible stabilisation has been utilised to maintain spinal mobility in patients with early-stage lumbar spinal stenosis (LSS). Previous literature has not yet established any non-fusion solution as a viable treatment option for patients with severe posterior degeneration of the lumbar spine. This feasibility study evaluates the mean five-year outcomes of patients treated with the TOPS (Total Posterior Spine System) facet replacement system in the surgical management of lumbar spinal stenosis and degenerative spondylolisthesis. Ten patients (2 males, 8 females, mean age 59.6) were enrolled into a non-randomised prospective clinical study. Patients were evaluated with standing AP, lateral, flexion and extension radiographs and MRI scans, back and leg pain visual analog scale (VAS) scores, Oswestry Disability Index (ODI), Zurich Claudication Questionnaire (ZCQ) and the SF-36 questionnaires, preoperatively, 6 months, one year, two years and latest follow-up at a mean of five years postoperatively (range 55–74 months). Flexion and extension standing lumbar spine radiographs were obtained at 2 years to assess range of motion (ROM) at the stabilised segment.Abstract
Objective
Methods
Although patient-reported outcomes (PROs) have become increasingly important in the evaluation of spine surgery patients, interpretability may be limited by a patient's ability to recall pre-intervention impairment. The accuracy of patient recall of preoperative back pain, leg pain, and disability after spine surgery remains unknown. We sought to characterise the accuracy of patient recall of preoperative symptoms in a cohort of lumbar spine surgery patients. We analysed consecutive patients undergoing lumbar decompression or decompression and fusion for lumbar radiculopathy by a single surgeon over a four-year period. Using standardised questionnaires, we recorded back and leg numeric pain scores (NPS) and Oswestry Disability Indices (ODI) preoperatively and asked patients to recall their preoperative status at a minimum of one-year following surgery. We then statistically compared and characterised patient recall of their pre-operative status and their actual pre-operative status. Patients with incomplete follow up or diagnoses other than degenerative lumbar stenosis were excluded. Sixty-seven patients with a mean age of 66.1 years (55% female) were included in the final analysis. All cases were either posterior or combined anterior/ posterior procedures. Mean levels of surgery was 1.7 and 93.8% of all cases were instrumented. Mean duration of preoperative symptoms was 44.5 months (3.7 years). Preoperative vs postoperative PROs improved with regards to NPS back (5.2 vs 2.2, p= to 2 point difference), exceeding the minimal clinical important difference (MCID) for NPS. This pattern was maintained across age, gender, and duration of preoperative symptoms. We also observed cases of symptom minimisation recall bias, and cases in which back and leg pain predominance were switched in severity during recall bias. Significant recall bias of preoperative symptoms exists in patients undergoing spine surgery, potentially limiting accurate assessment and interpretation of PROs. An understanding of PROs and their limitations is essential to assess treatment efficacy of spinal procedures.
The use of percutaneous Kirschner wires [K-wires] and plaster is a popular method of treatment for displaced distal radius fracture. However, multi-database electronic literature review reveals unsurprisingly different views regarding their use. From August 2002 till June 2004, 280 distal radial fractures were admitted to our orthopaedic department. They were recorded prospectively in the departmental trauma admissions database. We studied the 87 cases treated with the K-wires and plaster technique. They were classified according to the AO classification system. The mean patient age was 53 [5-88] years. The mean delay before surgery was 7 [0-24] days. We studied the complications reported by the attending orthopaedic surgical team. 48 out of 87 patients [55.1%] were reported to have complications. We analysed the displacement and the pin tract infection, as they were the main reported complications. 28 out of 87 patients [32%] had displacement [9 had further surgery to correct the displacement, 19 did not have any further surgery as the displacement was accepted]. 11 out of 87 patients [12.6%] had pin tract infection [7 needed early removals of the K-wires and systematic treatment]. Further analysis showed no statistically significant relation between the complications rate and the age of the patients, the delay before surgery or the type of the fractures. We demonstrate a considerable high displacement and infection rate with the use of K-wires and plaster technique for fixation of distal fracture irrespective of the age of the patients, the delay before surgery or the fracture classification. There are other methods for fixation of the distal radial fracture with proven less morbidity which should be considered.
