Case ReportsIdiopathic Charcot's arthropathy. Report of one case.
The authors describe a case of idiopathic Charcot's joint in a 67-year-old lady. The diagnosis was made after a careful screening that ruled out all the common causes, known so far, of Charcot's joint.

Osteoblastoma, defined as a benign bone tumor by Jaffe and Lichtenstein, together with osteoid osteoma and multifocal osteoblastoma, belongs to the osteoblastic tumors. Due to the variable features of this tumor, differential diagnosis comprises fibrous dysplasia, giant cell tumor, aneurysmal bone cyst and osteoid osteoma; histological analysis is the only way to obtain a definite answer about the tumor type. Occasionally differential diagnosis from aggressive osteoblastoma and osteosarcoma may be difficult. The history of symptoms is usually long and diagnosis may be difficult both clinically and histologically.

Humic substances are polyphenolic compounds. They have antiviral as well as desmutagenic effects and react with biopolymers such as collagen; thereby they have no toxic side effects by oral administration. ⋯ As humic substances increase the mechanical and chemical resistance of collagen fibres and promote their "maturity", it seems likely that this effect of humic substances depends upon their interaction with the hydrogen bonding and covalent bonding of the collagen fibres. Such a conclusion is confirmed by the results of X-ray diffraction analysis.

Bad results after anterior advancement of the tibial tubercle for patello-femoral pain syndrome.
Seventy-one patients with patello-femoral pain syndrome were re-examined an average of 10 (range 8-12) years after anterior advancement of the tibial tuberosity. The clinical results were excellent in 8 (11%), good in 20 (28%), fair in 16 (23%), and poor in 27 (38%). ⋯ The results were worse in patients with Outerbridge grade III-IV cartilage damage. Since the clinical results deteriorated with time, this surgical procedure should no longer be used to treat patients with patello-femoral pain syndrome.

Three- to five-year results with the cementless Harris-Galante acetabular component used in hybrid total hip arthroplasty.
In this paper we present our 3- to 5-year results after hybrid total hip replacement using the cementless porous coated Harris-Galante acetabular component and the cemented Griss femoral component in 39 patients with 40 implantations. Postoperatively, mild to moderate pain was experienced by 16.1% of patients, mostly following hard activity. A slight to moderate limp occurred in 24.2%. ⋯ The postoperative range of motion was increased in 93.9%. Radiographically, none of the acetabular or femoral components had to be classified as unstable. Only one acetabular component displayed complete (i.e., along all interface zones) radiolucency and was therefore classified as possibly unstable.
