“…In fact, in the study of Rasmussen et al (2007), the curve shapes of the estimated GH-JRF were comparable with those from the in vivo study of Bergmann et al (2007), but the magnitude was slightly different. Thereafter, the study of Nolte et al (2008) obtained a closer concordance of the peak GH-JRF while using a muscular condition similar to that of Bergmann et al (2007). The components of the GH-JRF estimated with the present model partially correlate with the numerical results from the study of Yanagawa et al (2008).…”

This study assessed the influence of the medial offset of the proximal humerus on the glenohumeral destabilising forces during arm elevation in the plane of the scapula, using the AnyBody Modeling System. The variability of the medial offset was covered using literature data (minimum, 0 mm; average, 7 mm and maximum, 14 mm). The following parameters were studied: moment arm (MA; middle deltoid), muscle activity and stability ratios. The minimum offset decreased the MA of the middle deltoid ( -11%), increased its activation (+18%) and its superior destabilising action (+40%). The maximum offset had an opposite effect (+9%, -30% and -30%). The stabilising action of the rotator cuff was not affected. Varying the medial offset seems to have an influence on the destabilising action of the middle deltoid. The AnyBody simulation tool appears to be promising in establishing links between shoulder morphology and stability.

“…1 and 2), the deviations between the model estimations and measured forces primarily occur at arm elevations above 601. Since the studies by Nolte et al (2008) and Rasmussen et al (2007) looked at arm elevations below this angle, and keeping in mind that the input was based on an assumed scapular motion pattern, results of those studies should be interpreted with some caution.…”

“…Recent studies (Nolte et al, 2008;Rasmussen et al, 2007) have compared the analytical predictions with the published data from the first measured patient with the instrumented endoprosthesis (Bergmann et al, 2007). However, none of these studies used the simultaneous kinematic recordings of the same subjects, nor did they have the individual scapular motion available.…”

“…For the musculoskeletal simulation, the AnyBody Modeling System (AMS-AnyBody Technologies A/S, Aalborg, Denmark) Version 6.0 and basic human body model of the Anybody Managed Model Repository (AMMR-Version 1.6.2) were utilized. 18,22 The virtual musculoskeletal shoulder model used in this study consists of 118 muscle-tendon units and of five joints in total. The acromioclavicular (AC) joint, the sternoclavicular joint (SC), and the glenohumeral (GH) joint are all modeled as a ball-and-socket joint.…”

“…16,17 A previous study conducted by Nolte et al compared joint reaction forces predicted by inverse dynamics simulations including muscle forces. They used the AnyBodyModeling system (AMS-AnyBody Technologies A/S, Aalborg, DK) and compared it with in vivo contact forces measured by Bergmann et al 18,19 The study showed good compliance of the model predictions for glenohumeral abduction. Rotator cuff injuries during a static abduction/flexion task have been investigated by Steenbrink et al, using the validated Delft Shoulder and Elbow Model (DSEM).…”

One of the main goals in reconstructing rotator cuff tears is the restoration of glenohumeral joint stability, which is subsequently of utmost importance in order to prevent degenerative damage such as superior labral anterior posterior (SLAP) lesion, arthrosis, and malfunction. The goal of the current study was to facilitate musculoskeletal models in order to estimate glenohumeral instability introduced by muscle weakness due to cuff lesions. Inverse dynamics simulations were used to compute joint reaction forces for several static abduction tasks with different muscle weakness. Results were compared with the existing literature in order to ensure the model validity. Further arm positions taken from activities of daily living, requiring the rotator cuff muscles were modeled and their contribution to joint kinetics computed. Weakness of the superior rotator cuff muscles (supraspinatus; infraspinatus) leads to a deviation of the joint reaction force to the cranial dorsal rim of the glenoid. Massive rotator cuff defects showed higher potential for glenohumeral instability in contrast to single muscle ruptures. The teres minor muscle seems to substitute lost joint torque during several simulated muscle tears to maintain joint stability. Joint instability increases with cuff tear size. Weakness of the upper part of the rotator cuff leads to a joint reaction force closer to the upper glenoid rim. This indicates the comorbidity of cuff tears with SLAP lesions. The teres minor is crucial for maintaining joint stability in case of massive cuff defects and should be uprated in clinical decision-making. ß
