[Tönnis and Kalchschmidt triple pelvic osteotomy].

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics

Background:

• The Tönnis and Kalchschmidt triple pelvic osteotomy (TPO) has a 30-year track record at Klinikum Dortmund.
• TPO has successfully treated over 5000 cases of severe hip dysplasia.
• This technique is versatile, accommodating combined procedures and respecting growth plates for conditions like Legg-Calve-Perthes disease.

Purpose of the Study:

• To highlight the efficacy and versatility of the Tönnis and Kalchschmidt triple pelvic osteotomy (TPO).
• To emphasize the importance of surgical experience and team support in achieving successful outcomes.
• To discuss the role of advanced imaging and modern osteosynthesis in TPO procedures.

Main Methods:

• Conventional X-rays are primary for indication, with MRI/CT scans used selectively.
• EOS imaging aids in surgical planning and execution.
• Novel screw fixation techniques enhance osteosynthesis stability.

Main Results:

• TPO demonstrates significant potential in managing severe hip dysplasia.
• The procedure can be combined with other hip surgeries and addresses impingement.
• Respect for growth plates allows application in Legg-Calve-Perthes disease.

Conclusions:

• Successful TPO requires surgical expertise, a dedicated team, and comprehensive patient care.
• Modern osteosynthesis contributes to stability, enabling shorter hospital stays and early mobilization.
• Careful patient selection and management are crucial due to the elective nature of the surgery.
