• ABSTRACT
    • Web creep is a common complication following surgical release of syndactyly. Currently, normal web height has not been objectively determined, which prevents accurate analysis of the degree of web creep after surgery. The purpose of this study was to design a technique to reproducibly measure web height and to define the standard web height in a control population. Four hundred thirty-seven standard left posteroanterior hand x-rays of children without any upper extremity pathology were evaluated. Web height was measured as a relative ratio to digital length using standard landmarks. All measurements were tabulated according to gender, age, and web space. Statistical analysis was performed to determine the reliability of this technique and to delineate any differences between web space, gender, and age. There was no significant intraobserver or interobserver difference and web height was similar in males and females. There was a significant difference between web height with respect to web location and age. Normal ranges of web height with regard to age and web position were determined and plotted as graphs. Using this measurement method, web creep can be evaluated and comparison studies of different surgical techniques performed.
