Factors associated with heterotopic bone formation following total hip replacement.
In order to delineate groups of patients suitable for treatment to prevent heterotopic bone formation (HBF) following total hip replacement, 99 patients were examined to evaluate predisposing factors. One year after surgery, HBF was found in 73% of the patients. ⋯ Previous ipsilateral hip surgery did not increase the risk of HBF. Although not significant, all patients who developed heterotopic bone after previous ipsi- or contralateral hip surgery showed HBF of the same or even a higher grade after the present replacement.

Evidence for spirochetal origin of Sudeck's atrophy (algodystrophy, reflex sympathetic dystrophy).
Four female patients with Sudeck's atrophy (SA) were evaluated at our department. Sera of all patients were investigated for antibodies against Borrelia burgdorferi. ⋯ In one patient structures identical with B. burgdorferi could be detected on histological sections from the skin of the affected limb. Our data and those of other authors suggest that a spirochetal infection can be regarded as an important etiopathogenetic factor in the development of SA.
