Hip unit

The hip unit of the Department of Orthopedics of the Sint Maartenskliniek has a long tradition of hip surgery: clinical expertise exists in the field of pediatric hip deformities, hip osteotomies, reconstructive surgery for degenerative hip disease, and arthroplasty and revision arthroplasty surgery. The hip research line concentrates on total hip arthroplasty.

Hip arthroplasty
There have been several cohort studies in the past years, analyzing different hip arthroplasty aspects (straight stem Muller total hip arthroplasty survival, Wagner total hip revision outcome) and currently analyzes the uncemented RM-cup fifteen years survival. This earlier work on the RM-cup is continued, evaluating different aspects of the iso-elastic properties of the cup through literature studies and stress shielding analysis by means of finite element analysis and DEXA and CT assessments of bony areas around the cup.

For aftercare of total hip replacement surgery, the hip unit evaluates efficacy of post clinical physiotherapy in a randomized trial.

A list of the hip studies follows: 

• Health service utilization of patients with end-stage oa of the hip or knee
• Risk on cancer after first knee or hip arthroplasty
• ISO elasticity of the RM cup
• Efficacy of post clinical physical therapy on functional after total hip arthroplasty
