| pubmed-article:404773 | pubmed:abstractText | Systematic examination of 733 cases of replacement of the hip-joint, operated on with an identical technique and method of post-operative treatment. Frequency and severity of periarticular ossification, their relationship to pre-operative arthrosis and their effect on joint function are described. Development and localization of periarticular ossification, their higher incidence after tearing off of the trochanter, removal of osteophytes and occurrence of hematomata hint at surgical trauma as one of the causes. Preliminary operations on the proximal end of femur did not influence ectopic ossification. Ossification of grade I did not interfere with function, grades II and III limited movement in varying degrees. | lld:pubmed |
