Influence of an Anterior Latarjet-type Abutment Operation on Scapular Dyskinesia and the Muscular Stabilization Mechanisms of the Scapula (DyScapLat)

Influence of an Anterior Latarjet-type Abutment Operation on Scapular Dyskinesia and the Muscular Stabilization Mechanisms of the Scapula (DyScapLat)

The aim of this study is to assess the influence of anterior abutment surgery using the Latarjet method on the kinematics of the scapula. The sub-objectives will be to show that Latarjet-type surgery does not lead to scapular dyskinesia and modification of muscle activity compared to a control group that has not undergone an operation.

Inclusion Criteria:

• Patient Group:

  • Male between 18 and 40 years-old
  • Practice a regular sports activity before the injury (s) requiring surgery
  • Present the clinical criteria leading to anterior abutment surgery using the Latarjet method
  • Surgery performed by surgeons from the Jean-Mermoz Private Hospital (69008 Lyon)
  • Have followed a post-surgery self-rehabilitation program

Control group:

• Male between 18 and 40 years-old
• Practice a regular sports activity

Both group:

oPatient having signed an informed consent o Subject affiliated or beneficiary of a social security scheme

Exclusion Criteria:

Patient group:

• Have another shoulder pathology on the side of the operated limb or on the contralateral side
• Present a constitutional hyper laxity
• Have stiffness or recurrence of dislocation of the shoulder post-surgery
• Have a body mass index greater than 30 kg / m² (to ensure sufficient accuracy to measure the movements of the scapula)
• Wear a pacemaker or any other metal device (e.g. patch with metal material)
• Present a contraindication to the use of measuring devices (intolerance to a weak electromagnetic field)

Control group:

• Present during the study or have presented in the past any musculoskeletal pathology in the right or left shoulder (WOSI or WORC score greater than 250).
• Have a body mass index greater than 30 kg / m² (to ensure sufficient accuracy to measure the movements of the scapula)
• Wear a pacemaker or any other metal device (e.g. patch with metal material)
• Present a contraindication to the use of measuring devices (intolerance to a weak electromagnetic field)

Both group :

o Protected subject: adult under guardianship, curatorship or other legal protection, deprived of liberty by judicial or administrative decision
