“…At our institution we undertook a systematic approach to develop a method to classify shoulder instability—the FEDS classification 26. We performed a systematic review of the literature to identify proposed classification systems, and determined which features of instability were used most commonly (figure 2).…”

Glenohumeral joint instability is extremely common yet the defi nition and classifi cation of instability remains unclear. In order to fi nd the best ways to treat instability, the condition must be clearly defi ned and classifi ed. This is particularly important so that treatment studies can be compared or combined, which can only be done if the patient population under study is the same. The purpose of this paper was to review the problems with historical methods of defi ning and classifying instability and to introduce the FEDS system of classifying instability, which was developed to have content validity and found to have high interobserver and intraobserver agreement.

“…It is also common for systems to be based solely on single or small group expert opinion with meager or absent descriptions of the developmental process 13 . Consensus regarding the optimal classification system is often lacking, which leads to confusion both in the clinical realm and in the research domain [14][15][16] .…”

Utilizing formal consensus-building methods in a large group of surgeons experienced in treating early-onset scoliosis, a novel classification system for early-onset scoliosis was developed with all core components demonstrating substantial to excellent interobserver reliability. This classification system will serve as a foundation to guide ongoing research efforts and standardize communication in the clinical setting.

“…Despite the limitations in diagnosing MDI 36 54 there are aspects of our diagnostic criteria that are likely to improve the diagnostic accuracy. First, we are combining more than one type of test to assess any one direction of instability; draw tests and the apprehension tests.…”

Effect of exercise-based management on multidirectional instability of the glenohumeral joint: a pilot randomised controlled trial protocol

et al. 2016

IntroductionThe most commonly recommended treatment for multidirectional instability (MDI) of the shoulder is exercise. Despite this recommendation, there is limited evidence to support the effectiveness of exercise. The aim of this paper is to describe a pilot randomised controlled trial comparing the effectiveness of 2 exercise programmes on outcomes of participants with MDI.Methods and analysisConsenting participants between 12 and 35 years, with non-traumatic MDI will be randomly allocated to participate in either the Rockwood Instability programme or the Watson MDI programme. Both programmes involve 1 consultation per week for 12 weeks with a physiotherapist to prescribe and progress a home exercise programme. Outcomes will be assessed at baseline, 6, 12, 24 and 52 weeks. Primary outcome measures include the Melbourne Instability Shoulder Score and Western Ontario Shoulder Index. Secondary outcomes include scapular coordinates, scapular upward rotation angles, muscle strength, symptomatic onset, limiting factor and angle of limiting factor in abduction range, incidence of complete glenohumeral joint dislocation, global rating of change, satisfaction scores, the Orebro Musculoskeletal Pain Questionnaire, adverse events and compliance with the home exercise programme. Data will be analysed on intention-to-treat principles and a per protocol basis.DiscussionThis trial will evaluate whether there are differences in outcomes between the Rockwood and the Watson MDI programmes for participants with MDI.Ethics and disseminationParticipant confidentiality will be maintained with publication of results.

Development and reliability testing of the frequency, etiology, direction, and severity (FEDS) system for classifying glenohumeral instability

Abstract: Background-Classification systems for glenohumeral instability (GHI) are opinion based, not validated, and poorly defined. This study is designed to methodologically develop and test a GHI classification system.
