Total Shoulder Replacement – Long Term Follow Up with the Constant Score

Background    

Total shoulder replacement* has become a mainstay for several painful shoulder conditions when non-operative treatments fail and in the majority of cases, the surgery provides predictable pain relief, mobility and functional improvement with satisfactory longevity.

Patient satisfaction, however, has been seen to fall short immediately following the surgery but improve with time. With this study, we wish to see how outcomes vary both in the short and long term and improve upon the paucity of long term data both locally and globally.

The Constant Score^ is a widely used shoulder-specific scoring system. Devised by Christopher Constant in 1987, this functional assessment score was conceived as a system of assessing the overall value, or functional state, of a normal, diseased or treated shoulder. In 1992, the European Shoulder and Elbow Society mandated the use of the Constant Score in all peer-reviewed papers, making it the most widely used shoulder evaluation instrument in Europe (and around the world). It is reliable and reproducible, providing a subjective and objective measure of patient symptoms and strength. It also provides an important measure for patient follow up and has the potential to highlight specific patient concerns.

Objectives

The objective of this study is to evaluate the long term subjective and objective outcomes in patients undergoing total shoulder replacement using the Constant Score.

Design

This is a prospective observational study.

Study Procedure

All participants meeting inclusion criteria will be administered the Constant Score pre-operatively and then post-operatively each year from 1 to 10 years.

Inclusion Criteria

  • Patients undergoing total shoulder replacement surgery
  • Willingness to give written informed consent and willingness to participate in and comply with the Study

Exclusion Criteria

  • Patients undergoing total shoulder replacement surgery as a result of trauma eg fracture

Status

Participants are at various stages of data collection. Earliest recruits have reached the 4 year post-operative follow up mark.
