The effect of clinical, radiographic and functional scores on the total score in the evaluation of congenital clubfoot.

INTRODUCTION

The use of radical surgical treatments in treating congenital clubfoot is decreasing. Minimally invasive surgical treatment (MIST) is a way of treating congenital clubfoot, which is a kind of compromise between a radical surgical treatment and non-operational one. A few protocols of different authors McKay, Macnicol, Stevens, Meyer, G.W.Simons and Laaveg-Ponseti were used in the evaluation of the results. SCIENTIFIC OBJECTIVE: To determine the importance and role of groups of parameters (clinical, radiographic and functional) in the evaluation of the results in patients treated with the two methods (radical operation and MIST).

SUBJECTS AND METHODS

This paper covers children who were treated for structural (idiopathic) form of PEVC. The testing is a prospective study and was conducted in two groups of patients. Group A (radical surgical treatment) - control group, where the total number of subjects was 50, out of which 35 male (70%) and 15 female (30%). The number of feet tested was 88. Group B (minimally invasive surgical treatment-MIST)-experimental group. The total number of subjects was 48, out of which 35 male (73%) and 13 female (27%). The number of feet tested was 84. For the analysis of the results, we used a questionnaire. The total number of parameters was fifteen, clinical, radiographic and functional, five parameters of each. Normal findings or measured value was determined by 0 points. The range of the total score (TS-a- total score range) 0-27 points, and the results were sorted out into the folowing categories: good result (0-5) satisfactory (6-11), poor (12-19) and deformity recrudescence (20-27) points.

RESULTS

The proportion of good results at 88 feet in group A was 0,477 as at 84 feet in group B it was significantly higher and came to 0,893. The difference between these proportions is statistically highly significant (t = 5.84, p <0.001). Chi-square test (χ2 = 30.083 df = 1 N = 172, p <0.001) indicated that there is a highly significant correlation between the method of treatment used and results of treatment. Good results of treatment in group A were observed in 48% and in group B in 88% of cases. The Charles Spearman nonparametric method showed that the rank correlation coefficients for the group A are positive, quite high (between 0.70 and 0.85), similar and statistically highly significant (p <0.001). The influence of radiographic scores on the total score is the lowest, and clinical score on the overall score is the highest. Rank correlation coefficients for group B were also positive but somewhat smaller than in group A (between 0.55 and 0.75) and statistically highly significant (p <0.001). It is possible to notice the difference here and say that the impact of functional scores on the total score is the highest and of radiographic score the lowest.

CONCLUSION

Minimally invasive surgical treatment (MIST) gives better functional results in the treatment of congenital clubfoot than radical surgical treatment. The role of radigraphic parameters in the evaluation of the results of the treatment was the slightest regardless of whether the treatment was radical surgery or MIST. We believe that radiography for routine analysis of the results of treatment need not be used.
