Short-term Results After Minimally Invasive Chevron Osteotomy for Hallux Valgus Correction

Short-term Results After Minimally Invasive Chevron Osteotomy for Hallux Valgus Correction in Comparison to the Open Technique

By means of clinical satisfaction and clinical scores comparison of an open to a minimally invasive distal chevron osteotomy for correction of a hallux valgus deformity is performed.

The aim of this study is to evaluate shortterm clinical outcome after a minimally invasive chevron osteotomy technique for correction of hallux valgus deformity in comparison to the open distal chevron technique. Patients undergoing a distal chevron osteotomy for correction of a hallux valgus deformity are assigned to one of the two groups. Survey is taken preoperatively, after 2, 4, 6 and 12 weeks postoperatively. Assessment of the clinical outcome measures in terms of the range of motion (ROM), Visual Analogue Scores (VAS) of pain, the American Orthopaedic Foot and Ankle Society (AOFAS) forefoot Score and a patient satisfaction score and a Life Quality score (SF 12) as well as the evaluation of the Charlson Comorbidity score is performed. It is hypothesized, that clinical outcome with the minimally invasive distal chevron osteotomy is superior to the open technique.

Inclusion Criteria:

• all patients undergoing hallux valgus correction by means of a distal chevron osteotomy

Exclusion Criteria:

• surgery on the lesser rays of the same foot
• mental illness with impossibility to follow the postoperative protocol
