THREE SHOULDER SCORING SYSTEMS IN INDIVIDUALS WITH NORMAL SHOULDER FUNCTION



Abstract

The aim of this study was to evaluate how three different scoring systems (Constant, Reichelt, and UCLA scores) perform in individuals with normal shoulder function.

Scoring systems to evaluate the outcome of surgical treatment around the shoulder are well established. A total of 201 individuals were enrolled in this study. They were divided in four age groups and divided by sex: Group 1: Under 50 years of age: 25 female, 21 male; Group II: From 50 to 59 years of age: 17 female, 21 male; Group III: From 60 to 69 years of age: 18 female, 12 male; Group IV: 70 years of age and older: 24 female, 15 male.

All underwent clinical examination, ultrasound examination for detection of cuff tears, and radiograph examination in three planes. In all cases the dominant arm was enrolled. Twelve patients were excluded from the study because ultrasound depicted cuff tear or radiograph showed more than mild osteoarthritis according to the criteria of Hawkins, et al. (1990).

The main factor influencing the over-all score was the age-dependent decrease of muscle force measured in forward arm flexion (max. 12.5kp). The score was also influenced by the limitation of internal rotation (Group I: 13%, Group II: 26%, Group III: 40%, Group IV: 41%). According to the Reichelt and UCLA scores, males in Groups I, II and III reached a 100% top score in the UCLA and Reichelt scoring systems. In Group IV composed of older male patients, 20% scored less that the top score because of loss in active motion and muscle force. Only females in Groups I and II scored maximum results. Females in Group III scored 11% and in Group IV composed of older female patients, 50% scored less than the top score because of loss in active motion and muscle force.

Due to the natural aging process, males and females in Group IV could not accomplish maximum scores. We recommend that the top scores for the oldest age group be adjusted in order to avoid drawing erroneous conclusions from the scores in this age group.
