Heterotopic ossification after total hip replacement.

View original source ↗Export metadata ↓

Abstract

Heterotopic bone formation occurs in up to 70% of patients who have undergone a total hip arthroplasty. Although histologically similar to mature skeletal bone, the ectopic tissue limits postoperative motion and causes pain in 2% to 4% of patients. The ossification is classified and graded according to radiographic appearance. Males with bilateral hypertrophic osteoarthritis who have had prior hip surgery are at high risk. Prophylaxis with Indocin or low-dose irradiation treatment is effective. Excision and irradiation therapy can treat established bony bridges.

[Cripples at the medieval hospital of Bátmonostor, Hungary--archeological findings].

Cripples from the medieval hospital of Bátmonostor, Hungary. People with disabilities were generally burdened with a painful fate in ancient times, however in the hospitals was no effective therapy. The hospital of Batmonostor was founded at late 13th century, The authors examine by morphological, radiological and histological methods 426 complete skeletons excavated from medieval (14th-15th century) cemetery of Bátmonostor (Hungary). Among them 30 cases (7.1%) of bony ankylosis, (24 cases on lower limb and 6 cases on upper limb) was found. Sacroiliac ankylosis 3 cases, Bechterew's spondylitis ankylopoetica 1 case was seen. Spondylitis tuberculosa and malum Potti 4 cases, and hunchback with other aetiology 2 cases was detected. Beside the cases with ankylosis severe posttraumatic osteomyelitis (7 cases), primary malignant bone tumors (2 cases) and an osteoplastic metastatic tumors (probably prostata carcinoma) was diagnosed. Paleopathologic study of the physically disabled may yield information and insight on the prevalence of crippling disorders. The authors hypothetize, that crippled persons lived in the hospital until their deaths.
