To evaluate the biomechanical performance of Femoral Neck System (FNS) versus Hansson Pin (Hansson Pins) with two parallel pins in a Pauwels II femoral neck fracture model posterior comminution.Forty-degree fractures AO 31-B2.1 15° wedge were simulated fourteen paired fresh-frozen human femora, followed by instrumentation either FNS or Pins pair-matched fashion. Implant positioning was quantified measuring shortest implant distances to inferior cortex (DI) and (DP) on anteroposterior axial...
Introduction Glenohumeral (GH) stability is a delicate interplay between bony congruence, muscle contraction, and ligamentous or capsular that can be disrupted by pathologies such as rotator cuff (RC) tears. We aimed to develop an advanced musculoskeletal shoulder model incorporates subject-specific GH joint contact, active passive stability, mechanical properties of ligaments calculate translation using force-dependent kinematics (FDK). hypothesized inferior-superior computed this are...
Introduction: Osteoarthritis (OA) and rotator cuff tear (RCT) pathologies have distinct scapular morphologies that impact disease progression. Previous studies examined the correlation between morphology glenohumeral joint biomechanics through critical shoulder angle (CSA) variations. In abduction, higher CSAs, common in RCT patients, increase vertical shear force activation, while lower OA are associated with compressive force. However, of complete patient-specific remains unexplored due to...
Compromised abduction ability after reverse shoulder arthroplasty is primarily linked to limited glenohumeral range of motion while scapulothoracic mobility can typically be maintained. Glenohumeral joint forces strongly depend on the resulting scapulohumeral rhythm, however, an association between acting muscle and subject-specific rhythm has not been established.Eleven patients were divided into groups poor excellent ability. Subject-specific models developed scaled for each patient using...
