Comparison of Functional Outcome Scores in Radial Polydactyly

Abstract

Interobserver reliability was highest for the JSSH classification, which also showed superior correlations with both examiner-rated and patient-rated VAS scores for functional and aesthetic outcome compared with the other nine assessment systems. The finding of a poor correlation between the outcome scores and the results of manual activity questionnaires is in agreement with findings in published literature. We recommend the JSSH assessment method for the scientific evaluation of the outcomes, in terms of body structure and function, of the treatment of radial polydactyly.

Classifications in Brief: The Wassel Classification for Radial Polydactyly

“…Since its original description, many, including the membership of the Pediatric Hand Study Group (an international academic society of pediatric hand surgeons and hand therapists) call this classification system the ''Flatt Classification'' to acknowledge the intellectual genesis of this classification from Adrian Flatt, MD [25]. The term Flatt Classification has now been adopted in the pediatric hand surgery literature [6,9,12,18,23,25,27].…”

Do Patient- and Parent-reported Outcomes Measures for Children With Congenital Hand Differences Capture WHO-ICF Domains?

“…Nine PROMs evaluated only one ICF domain. Of the 19 validated PROMs used in the 42 studies, only the Prosthetic Upper Extremity Functional Index (PUFI) has been validated specifically in the CHD population (children with congenital longitudinal and transverse deficiency) [7,8,22,48]. Only the ABILHAND-Kids Questionnaire, Disabilities of the Arm, Shoulder and Hand (DASH), Pediatric Outcomes Data Collection Instrument, PUFI, and QuickDASH were developed specifically for use in patients with orthopaedic/upper extremity pathology [7,8,22,26,35,44,48,72].…”

Clinical Findings and Treatments of a Radially Deviated Type of Thumb Polydactyly

“…The postoperative outcomes were evaluated using the scoring system that was established by the Japanese Society for Surgery of the Hand (JSSH), which has high interobserver reliability and excellent correlations with both examiner-rated and patient-rated visual analogue scale scores for functional and aesthetic outcomes (Table 1). 4) A score of 14 points for function comprises two points each for metacarpophalangeal joint (MPJ) and interphalangeal joint (IPJ) alignment, MPJ and IPJ instability, active flexion, extension lag, and active palmar abduction. Four points for cosmesis comprise one point each for size, pulp or nail, scar, and bony prominence at the MPJ; and the two points for subjective outcome comprise one point each for pain and satisfaction scored by patients and their parents.…”
