[Experiences with Wagner's hip joint cup endoprosthesis. Indication, results complications]. 1984

H O Dustmann, and G Godolias

In the last 5 years the authors have installed Wagner hip joint cup prostheses in 260 patients. Of these, 211 were implanted with an iliofemoral approach after Smith-Petersen, severing the pelvitrochanterian musculature, and 49 with a lateral approach after Watson-Jones, modified after Harris, with temporary ablation of the trochanter major. Altogether, 160 of the patients thus treated were followed up 3, 6, 18, 24, 30 and 36 months after surgery. The most common postoperative complication, found in 36% of those examined, was periarticular calcification, which was rated as severe in 5%, moderate in 15% and slight in 16%. Even though the periarticular ossifications did not necessarily lead to severe restrictions of movement, the patients with severe and moderate calcifications who were examined after 3 years were found to have a reduction of function of approx. 24% in flexion and extension, approx. 50% in abduction and adduction and approx. 57% in internal and external rotation compared with preoperative findings. In contrast, patients with no significant periarticular ossifications were found to have a definite improvement in motility 3 years after surgery as compared to their preoperative conditions. Further important complications were 2 infections, 3 fractures of the neck of the femur, 3 slipped prostheses and 23 cases of loosening of the prosthesis. The number of loosened prostheses (9% of those examined) represents a marked increase as compared to the loosening rate with conventional total hip replacements.(ABSTRACT TRUNCATED AT 250 WORDS)

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.
