Study to Evaluate the Performance and Safety of ATF Implants and Lapé Médical Devices Implanted During Hip Arthroplasty

Inclusion Criteria:

• Male or female indicated for hip replacement surgery with hip prosthesis manufacturedby ATF Implants and/or Lapé médical; There are different indications for hip replacement surgery. The main ones are listedbelow:
• Dysplasia
• Primary Coxarthrosis
• Secondary Coxarthrosis
• Perthes disease
• Epiphysiolysis
• Ankylosing spondylitis
• Trochanteric bursitis
• Arthritis
• Degenerative arthritis
• Post-traumatic arthritis
• Rheumatoid arthritis
• Femoral neck fracture
• Osteonecrosis
• Revision Depending on the specificities of the devices (size, absence/presence of a coating,material), indications may vary. This information can be found in the instruction for use.It is the surgeon's responsibility to select the most appropriate prosthesis for a givenpatient according to the patient's medical records and the instruction for use in force atthe time of the procedure accompanying the medical device.

Exclusion Criteria:

• There are various contraindications for hip arthroplasty. The main ones are listedbelow:
• An acute or chronic, local or systemic infection
• Severe muscular, neurological or vascular deficiency compromising the affectedextremity
• A bone defect or insufficient bone quality that may compromise the stability ofthe implant
• Any concomitant disease (dysplastic coxarthrosis with extreme coxa valga, shortneck and severe varus) that may affect the function of the implant
• Sensitivity to the material (allergy) Depending on the specificities of thedevices (size, absence/presence of a coating, material), contraindications mayvary. This information can be found in the instruction for use of the devices.
