It is reported about a young girl with congenital agenesis of the os sacrum, a congenital platfoot and a luxation of the left hip. These congenital malformations can be found in children born to diabetic mothers.
Hemangiopericytomas are very rare tumors that mostly develop in the soft tissues. In rare cases, however, they may occur as primary bone tumors which are extremely rare. In case of such an intraosseous tumor, a bone metastasis of such a soft tissue sarcoma must be considered first and has to be excluded. In a 62 year old female, a hemangiopericytoma of the left femoral neck was diagnosed that had induced a pathological bone fracture. A resection of the femoral head and neck was performed. Anamnestical investigations, however, have shown that 4 years before, such a tumor of the pelvic soft tissues was removed. Thus, the lesion of the femoral neck had to be classified as bone metastasis of a malignant hemangiopericytoma. It has to be emphasized that this special tumor always shows a questionable prognosis and, by histological investigations, it cannot be decided if we are dealing with a benign or malignant tumor growth. Diagnostic managements and clinical problems with hemangiopericytomas are discussed in detail.
It is reported in two cases of synostosis of the vertebral which is related in the Medical literature as "Dysontogenetic blockbuilding of the Corpus Vertebrae". This condition could be seen in a 13 year old boy in the area of Th 9 to Th 12 and in a 13 year old girl from Th 11 to L1. The clinical and radiological findings of these two cases will be described and discussed. An attribution of these cases to the "Dysontogenetic blockbuilding" groups was based on a disturbance of the vertebral forming. A causal therapy is not possible.
In 11 cases an arthrosis of the knee joint was treated by intraosseus osteotomy of the distal femur in one case of the proximal tibia only; in one case additionally an intraosseus osteotomy of the proximal tibia was performed. In a 2 to 5 years follow-up examination only 4 patients were subjectively satisfied with the operation.
A problematic case of pyoderma gangraenosum in a patient with colitis ulcerosa mimicing an empyema of the knee joint is reported.
The spontaneous idiopathic osteolysis is know as a slow progressive absorbtion process of the bone with unknown causes. It is supposed that in the "Gorham-Syndrom" a hämangiomatosis of the bone exists. In some cases of spontaneous osteolysis there wasn't any vascular proliferation noted. One case with spontaneous osteolysis will be discussed. The histological picture of this patient is described as a chronic uspecific osteoarthritis. Another case could be documented radiologically at the left distal ulna. The attribution of these cases to the "Gorham-Syndrom" is discussed.
The operation technique of the V-Y correction in varus deformity of the fifth toe and the necessity of a correct technique is demonstrated. 16 patients who had been operated on by this procedure could be followed up. In 11 patients good results were to be seen.
It is reported about hypertrophy of the nuchae ligament in an 28 year old woman. After operation (extirpation) the mobility of the cervical spinal column was nearly free and the permanent headache of the patient had gone.
