Spinal stenosis and low-grade spondylolisthesis produce symptoms of neural compression that can be treated with extreme lateral lumbar interbody fusion (XLIF) via indirect decompression. This study aimed to investigate whether the restoration of disc dimensions would relieve symptoms of radiculopathy, claudication and back pain. In this retrospective study, patients undergoing XLIF surgery for relief of radicular symptoms or degenerative disc disease were included. Radiologically proven changes were used to assess the modes of degeneration. Objective measures such as the Visual Analogue Scale (VAS) for back and legs and the Oswestry Disability Index (ODI) were used. Complications were collated post-operatively from clinical notes and outpatient appointments. Twenty-three consecutive patients were included, of whom 91% had spinal stenosis. The cohort presented with multiple comorbidities and 35% of the cohort had undergone previous lumbar surgery. There was a 61% improvement of coronal Cobb angle and an 11% correction of the lordosis sustained 1year after surgery. Clinical outcomes at 1year showed 39%, 50% and 60% improvements in the ODI, back and leg VAS scores respectively. 48% of patients had reduced sensation related to lumbosacral plexus manipulation and one retroperitoneal haematoma was conservatively managed. Minimally invasive spinal (MIS) XLIF resulted in effective restoration of disc dimensions via indirect decompression, providing good relief of clinical symptoms evidenced by significant improvement in clinical outcome scores. XLIF corrected scoliosis and improved lumbar lordosis significantly. Several plexopathies did not hinder long-term recovery. XLIF is highly suited to treating complex patients with multiple comorbidities and degenerative disease.
Effective clinician-patient communication is particularly important in ophthalmology where long-term adherence to treatment is often required. However, in the context of increasingly pressurised clinics, there is a tendency to resort to written information leaflets not suited to patients with visual impairment, non-English speakers or those with low levels of literacy. Video-based media could be harnessed to enhance clinician-patient communication. This systematic review aimed to assess the efficacy of using video-based media for patient education in ophthalmology. A pre-defined search strategy was used by two independent researchers to systematically review the PubMed, MEDLINE, EMBASE and PsycINFO databases. Eligible articles included peer-reviewed studies involving ophthalmology patients, who received a solely video-based educational intervention to assess for improvement in patient knowledge, behaviour and overall health-related outcomes. The search yielded 481 studies of which 31 passed initial screening. Following full-text analysis, 12 studies met the inclusion criteria, of which seven studies (58.3%) were randomised controlled trials. The majority of studies (58.3%) reported outcomes on patient comprehension with 5/7 (71%) showing statistically significant improvement after video intervention. Four studies (33.3%) reported on patient performance in a task (e.g. drop application method) or overall health-related outcome with 2/4 (50%) showing statistically significant improvement after intervention. Though more evidence is needed, the use of video-based media appears to be effective in improving patient understanding and in certain cases may ameliorate overall outcome. There is a paucity of well-designed studies and future research is required to fully examine the role of video-based media in patient education.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
