Patient Reported Function Following Combined First MTP and First TMT Arthrodesis.

What do Patients Report Regarding Their Real-world Function Following Combined First MTP and First TMT Arthrodesis?

The goal of the study is to gather sufficient patient data to assess real world postoperative function after a first metatarsophalangeal (MTP) joint arthrodesis done in conjunction with first tarsometatarsal arthrodesis (TMT) (double fusion). Many studies have demonstrated the success of a first MTP joint arthrodesis in eliminating pain and reducing the intermetatarsal angle. Very little research has been published to assess the outcomes of double arthrodesis. Limited research has specifically assessed patients' everyday function and gait following MTP arthrodesis and no studies are available to assess real world function following double arthrodesis. More data that includes patient reported function during activities of daily living is needed to understand the benefits and draw backs of combined first MTP/TMT joint arthrodesis used to treat and correct first ray deformity.

• Retrospective clinical data will be collected on a Clinical Data Collection Form from a chart abstraction at the research site.
• All radiographs will be anonymized and transferred in a secure process to a Central Radiologist for the study. The data will be collected in excel spreadsheet or on a Radiographic Data Collection Form.
• Post-operative function and satisfaction will be collected by study personnel via telephone call with the patient
• De-identified data will be entered into a database for analysis.
