Heinz Mittelmeier (born October 9, 1927 in Ingolstadt-Kothau / Bavaria ) is a German orthopedist.

Life

Mittelmeier spent his childhood in Weilheim and Sonthofen . In March 1945 he was seriously injured in his spine by shrapnel. He studied at the Ludwig-Maximilians-Universität in Munich from 1947 and also for a year in Graz (1950/51) and passed the medical state examination in Munich in 1953 with the grade very good. In 1950 he became interested in surgical orthopedics during an internship at the hospital in Bad Tölz under the direction of Max Lange, later professor of orthopedics at the Orthopedic Clinic of the Ludwig Maximilians University in Munich. There he got in touch with his then senior physician Alfred Nikolaus Witt.

He received his doctorate summa cum laude in 1954 from the Surgical University Clinic in Munich under EK Frey. From 1953 he worked for three years at the Pathological Institute in Munich-Schwabing under L. Singer, where he acquired the essential foundations for his later scientific work. He also completed a year in internal medicine at the Munich-Biederstein Municipal Hospital. He was able to begin his orthopedic training on February 1, 1957 with Alfred Nikolaus Witt at the Orthopedic Clinic and Polyclinic of the Free University of Berlin in the Oskar-Helene-Heim. This large and renowned orthopedic clinic had 430 beds at that time.

On January 21, 1960 he was recognized as a specialist in orthopedics. On April 1, 1960, he was appointed senior physician in the large children's department (110 beds). He completed his habilitation in orthopedics on November 20, 1961. The subject of the habilitation thesis was the use of plastic sleeves to avoid adhesions in tendon sutures. His inaugural lecture dealt with the particle disease after Plexiglas hip prostheses . On November 1, 1962, he was appointed senior physician in charge and permanent deputy to the clinic director AN Witt. In 1964, at the age of 36, he was offered the chair of orthopedics at the Saarland University and as director of the Orthopedic University Clinic and Polyclinic Homburg-Saar . He developed this clinic from a modest background into an orthopedic university clinic with a worldwide reputation. In 1966 he founded the state institute for physiotherapy / physiotherapy and was also the state doctor for the physically handicapped in Saarland during his tenure. In 1968 he was offered the chair of orthopedics at the Free University of Berlin to succeed his former teacher Afred Nikolaus Witt, which he refused. Retirement: March 31, 1996

Milestones

In 1956 he and L. Singer created the first publication on particle disease of the bone bed caused by endoprosthesis abrasion.

In 1959 he developed a metal hip clamp (now an angle plate) for covered osteosynthesis in the intertrochanteric femoral osteotomy of children with hip dysplasia. He realized this with a transverse incision, which was new at the time, with the removal of a precalculated bone wedge determined with a protractor. For the conservative treatment of hip dysplasia, he developed several splay pants from 1964.

In 1972 he was the first to develop a screw socket for hip endoprostheses , at that time made of metal and alternatively made of aluminum oxide ceramic Al 2 O 3 , a principle of implantation technology that has been established internationally to this day.

For decades he consistently represented the principle of cement-free anchoring of hip endoprosthesis stems in order to avoid the problem of cement fatigue in Charnley prostheses. He developed hip stems with surfaces such as supporting ribs and honeycombs to improve the anchoring of the endoprostheses in the bone.

In 1974 he finally succeeded in successfully introducing a high-strength aluminum oxide ceramic as a sliding surface in hip prostheses in collaboration with the Feldmühle companies (now CeramTec ) as well as Krupp and OsteoAG. With a monoblock ceramic screw cup made of Al 2 O 3 ceramic and ceramic heads, he was able to initiate and establish the development of ceramics in endoprosthetics worldwide, which he consistently accompanied with further developments and courses internationally until his retirement at the age of 69. The very abrasion-resistant ceramic enabled large head diameters (e.g. 38 mm) and thus a significantly lower risk of complications with regard to hip dislocation with endoprostheses.

He was also one of the international pioneers of carbon fiber-reinforced composite materials in implant technology and developed bone replacement materials as composite materials based on collagen and hydroxyapatite .
