We experienced one case of recurrent dislocation of the inner femoral head caused by wear of the bearing insert. The subject a 51 year-old woman with coxarthrosis had received bipolar hip prostheses with a self-centering mechanism approximately seven years earlier. She had been relatively young at the time of her first operation, was engaged in agriculture and enjoyed an active life after this operation. Seven years rater, she developed intermittent severe pain in her hip joint and was occasionally unable to walk. Examination revealed extreme varus alignment of the outer head and a radiolucent zone on the acetabular side. During surgery, we found fixed varus of the outer head, granulation of 3 to 4 millimeters on the acetabulum, and manifest wearing of all inner HDP liner, but failuer of the leaflet was not seen. This suggested that the wear occurred due to
We reviewed 3 patients treated for calcific tendinitis with subluxation of the shoulder joint. All patients were females with an average age of 58.7 years Patients complained of severe rest pain and inability to perform active elevation. Calcifications were found along the Rotator cuff tendons with part of them leaking out to the Subacromial bursa (SAB) on X-ray film, and the humeral heads were dislocated inferiorly by subluxation. After a few injections of steroid to the SAB, symptoms and calcifications were reduced and humeral heads had been completely repositioned. In subjects with no loosening, no cuff tears, and no paralysis of the axillary Nerve, we considered the main factor causing inferior subluxation of the shoulder joint to be dysfunction of the deltoid and Supraspinatus muscles to avoid pain.
A 51-year-old female presented with hip pain of 6 months duration and a rapidly destructive appearance of the femoral head radiographically.The patient had no clinical or laboratory evidence of sepsis or neurogenic disease.Femoral head replacement was performed.We describe the clinical, radiographic, and pathologic findings of this case which suggested rapid destructive coxarthrosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
