Clinical Trial Summary

Prospective observational study to evaluate the clinical and radiological predictors for outcome in hallux valgus (HV) corrective surgery.

Clinical Trial Description

Hallux valgus (HV) is the most common deformity in the adult forefoot. Characterizing and classifying HV primarily has been based on weightbearing radiographic imaging. Understanding of this pathologic process has mainly been confined to two planes, where the dominating modality of choice has been assessment by antero-posterior (AP) and lateral radiographs. From these two projections, imaging parameters have developed to define the severity of HV. With this understanding as the basis for describing the deformity, more than 140 operative techniques have been described. Although many of these techniques are of historical interest only, consistently favourable outcomes remain elusive even among more popular current techniques. HV corrective surgery is known to have mediocre results, with recurrence rate as high as 30-70%. Unsuccessful treatment of the condition is amongst the most common in the Norwegian patient injury compensation scheme. The variation in corrective techniques and the associated persistent and clinically significant rates of poor outcomes may indicate an incomplete treatment of the pathoanatomy of HV. Numerous recent publications have proved that the hallux valgus deformity should be viewed as a three-dimensional deformity. These recent studies have also pointed out new radiological parameters in AP and axial view, focusing on the multiplanar understanding of the deformity. The key challenge of the hallux valgus foot is the lack of clear guidelines for choosing the best treatment to these large group of patients. There is of today no guidelines nor consensus considering the indication for surgical treatment of the hallux valgus deformity. It is not known how much nuisance the patient should present before surgery could be worthwhile. Many studies have been made in the field of HV, but literature with the focus on comparing the surgical correction and the patient related clinical outcome is sparse and insufficient.

In this project the investigators primary aim is to investigate radiological and clinical factors that predict outcome in participants operated for hallux valgus deformity. ;
