Gender-specific Constant score correction for age

Abstract

To investigate the relationship between age, gender and the Constant score. Two hundred and seventy Healthy volunteers (527 normal shoulders) from our local population with no previous history of shoulder disease were assessed using the Constant score. The mean age was 43.9 years (16-86) and the mean Constant score 85.9 (56-100). The mean score was 88.1 (range 56-100) for men and 83.7 (range 60-100) for women. A mixed regression model estimated that, for the male population, the Constant score falls by 0.15 points per annum between the ages of 50 and 70 and by 1.3 points per year after the age of 70. Similarly, for the female population, the fall is of 0.25 per year between 60 and 70 and 0.35 after the age of 70. The changes are statistically significant (P < 0.01) and clinically important when comparing patients of different age groups.

Path analysis of factors for functional outcome at one year in 463 proximal humeral fractures

“…7 Our final path diagram shows a clear influence of age and sex on shoulder function after 1 year, which is well known. 40,44 Treatment was identified as another important prognostic factor, with LPHP fixation having a less favorable effect on the final outcome score compared with treatment with PHN. A similar effect was observed in a prospective cohort study comparing LPHP and nail fixation.…”

Surgical Treatment of Neer Group VI Proximal Humeral Fractures: Retrospective Comparison of PHILOS® and Hemiarthroplasty

“…AP and transscapular radiographic examinations at the time of injury, after surgery, and at the time of last followup (mean, 30 months; range, 12-83 months) were available for all patients. Functional and clinical assessments using the age-and gender-specific ConstantMurley [29] and the SF-36 [31] scores were performed at the last followup or at the time of a complication. Inclusion criteria were a traumatic Neer Group VI fracture treated either by the PHILOS 1 plate or primary HA and a minimum of 12 months followup.…”
