About
This study is an observational "change from baseline" outcome measures design. Data is collected for the sake of evaluating treatment (fusion surgery) performed as standard medical care, but the investigator does not assign specific interventions to any participants in this study.
Full description
Device/fluoroscopy measurements of arch motion and questionnaire data will be acquired on 10 women undergoing surgery for bunion, and 10 controls. Surgery will implant hardware to fuse (stabilize) the arch. Methods will evaluate the patient's problems associated with bunion and satisfaction with surgery, and assess the effectiveness of surgery in reducing motion of the arch. The hypotheses are that patients treated with surgery will demonstrate improvement in function, and that surgery will reduce motion of the arch postoperatively (posttest measures acquired 6 months after surgery), and in comparison to measures taken on a control group.
The data collected will come from a comprehensive examination. Methods will include the measurement of arch motion made by an examiner using a device and a fluoroscopic gait examination procedure, and completion of two medical questionnaires. The fluoroscopic acquisition of the digital images will be analyzed across the specified time dimensions of the gait cycle.
Device and fluoroscopy of measures of arch motion will be made at 2 time points on patients enrolled in this study: presurgery (baseline) and 6 months postsurgery. The questionnaire measurements of self-reported pain and function will be made at 4 time points: presurgery (baseline) and again at 3 months, 6 months, and 12 months postsurgery. Outcome measurements will be collected on control subjects at one time point only, on the day of their enrollment into the study.
Prospective studies have not characterized outcomes in patients receiving this type surgical fusion as part of the corrective treatment for bunion. Results have potential to improve surgical treatment outcomes and, improve upon the current methods of fluoroscopic motion analysis.
