hemicap, hallux rigidus
Brief summary
The purpose of this study is to examine variabel pressure gradients of the 1st toe, 2-5th toes and the metatarsal distal caput in patients who have had surgery with a partial proximal hemiarthroplasty in the 1st metatarsalphalangeal joint (MTP) between 2006-2014. Also, to examine these variables and compare them to the totalt range of motion and pain, to find out if the measured pedobar pressure can be used identify the well treated patient and the poorly treated patient. The pedobar pressure gradients will be compared with a control group with healthy feet.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Plantar forces under the hallux and the forefoot in patients operated with a hemiCAP in the 1st MTPJ. | One examination for each patient, approximately 30 min. | Plantar forces are measured under the hallux and the forefoot (plantar pressure (kPa), maximal force (N), and force/time (N/s)) is measured by the Emed foot pressure mapping system. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Range of motion (degrees) | One examination for each patient, approximately 30 min. | Unit: degrees. ROM of the hemicap operated 1st MTPJ |
| Level of pain | One examination for each patient, approximately 30 min. | Visual analog scale, 1-10 of the hemicap operated foot |
