Hallux Rigidus

Patients who have undergone arthrodesis of the first metatarsophalangeal joint due to hallux valgus or hallux rigidus are invited to participate in this study, which aims to investigate how the foot functions after this operation. Patients between 18 and 60 years of age at the time of surgery are eligible to participate. Questionnaires will be distributed to assess current sports function compared with function prior to surgery. Particular focus will be placed on function during cross-country skiing.

The system is composed of the HYALEX MTP Implant and instrumentation. The implant consists of the HYALEX Cartilage material bonded to a titanium backing.

The study in question is a post market clinical follow up (PMCF) study to evaluate the safety and performance of bioabsorbable headless compression screw Inion CompressOn in selected fracture, osteotomy and arthrodeses operations of the foot and ankle. The study recruits 125 adult patients who meet the acceptance criteria. The follow-up time for each study patient is 4 years. The study is a single center single group study which is conducted in Tampere University Hospital (TAYS) in Finland. The main focus of the study in terms of performance is to evaluate the bone healing/ossification of operated areas. The main focus of the study in terms of safety is to evaluate the occurrence of adverse events and required revision surgeries that are or might be related to the study device.
