Conditions
Outcome Measures
Primary Outcomes (1)
Clinical Outcome using a patient related outcome measure, the FAAM score (Validated Foot and Ankle Ability Measure). The score is a self-report outcome instrument developed to assess physical function. The change between the time points is measured.
FAAM score, the highest score is 100, indicating the best possible outcome
6 weeks, 3 months, 6 months, 12 and 24 months post surgery
Secondary Outcomes (5)
Duration of procedure
through study completion, an average of 2 years
Length of hospital stay
through study completion, an average of 2 years
Visual Analogue Scale (VAS) score. It is a measurement instrument for the amount of pain that a patient feels. The score is assessed preoperatively and the change between the time points is measured.
6 weeks, 3 months, 6 months, 12 and 24 months post surgery
Radiological union by evaluating conventional X-Ray. Preoperative X-Rays and postoperative X-Rays are comparted and the change in union in terms of bone densitiy is assessed postoperatively.
6 weeks, 3 months, 6 months, 12 and 24 months post surgery
Complications
6 weeks, 3 months, 6 months, 12 and 24 months post surgery
Study Arms (2)
Group A
ACTIVE COMPARATORPatients suffering from midfoot arthritis after failed prior conservative therapy who undergo a reverse distal metatarsal minimal-invasive osteotomy
Group B
ACTIVE COMPARATORPatients suffering from midfoot arthritis after failed prior conservative therapy who undergo a fusion of one or more midfoot (tarsometatarsal) joints
Interventions
minimal-invasive oblique osteotomy of the two or three metatarsal bones using a straight burr
open procedure with fusion and screw and plate fixation of two to three tarsometatarsal joints
