The role of MR imaging in staging femoral head osteonecrosis
(2007)
Reliability, accuracy and prognostic value of any classification system are important in evaluation and treatment of femoral head osteonecrosis. The purpose of the present study was to correlate the plain radiographs with ...
Hemiarthroplasty for three- and four-part displaced fractures of the proximal humerus in patients over 65 years of age
(2007)
This is a prospective case series, in which the outcome of shoulder hemiarthroplasty in recent three- and four-part fractures of the proximal humerus was evaluated in patients over 65 years of age. From February 1993 to ...
Lectin-like oxidized low density lipoprotein receptor 1 (LOX-1) expression in human articular chondrocytes
(2007)
Objective To investigate the involvement of oxidized low density lipoprotein (ox-LDL) and the expression of its receptor lectin-like oxidized low density lipoprotein receptor 1 (LOX-1) in osteoarthritis, by determining the ...
Distal ulnar implant arthroplasty as a definitive treatment of a recurrent giant-cell tumor
(2007)
Giant-cell tumors of the distal ulna are frequently recurrent and difficult to treat. A Darrach-type resection can lead to functional impairments of the wrist and hand. A case of a 42-year-old man, who underwent a distal ...
Incision stretching in primary TKA: What is the real length of our approach?
(2007)
This article examines the extent of anterior knee soft-tissue stretching. that occurs in patients undergoing primary total knee arthroplasty for 331 consecutive patients. At the time of surgery, an anterior knee incision ...
Femoral head osteonecrosis: Volumetric MRI assessment and outcome
(2007)
Effective treatment of femoral head osteonecrosis (FHON) requires early diagnosis and accurate assessment of the disease severity. The ability to predict in the early stages the risk of collapse is important for selecting ...
Osteonecrosis of the femoral head: Etiology, imaging and treatment
(2007)
Osteonecrosis of the femoral head is a disabling clinical entity affecting young adults that usually leads to destruction of the hip joint. A high index of suspicion is necessary for the diagnosis due to the insidious onset ...
Differential expression of leptin and leptin's receptor isoform (Ob-Rb) mRNA between advanced and minimally affected osteoarthritic cartilage; effect on cartilage metabolism
(2007)
Objective: To investigate leptin's effect on cartilage metabolism and the pathophysiology of osteoarthritis (OA). Methods: Messenger RNA (mRNA) expression and protein levels of leptin and leptin's receptor isoforms were ...
Epigenetic regulation of leptin affects MMP-13 expression in osteoarthritic chondrocytes: possible molecular target for osteoarthritis therapeutic intervention
(2007)
Objective: To investigate whether epigenetic mechanisms can regulate leptin's expression and affect its downstream targets as metalloproteinases 3,9,13 in osteoarthritic chondrocytes. Methods: DNA methylation in leptin ...
Low-molecular-weight heparin for prevention of thrombosis: Inverted role
(2007)
BACKGROUND: Heparin induced thrombosis (HIT) after low-molecular-weight (LMWH) administration for thrombosis prevention is a limb and life threatening condition. METHODS: Two previously healthy individuals, with nonviable ...
