1. 1. Temporomandibular joint disk displacement and subsequent adverse mandibular growth : a radiographic, histologic and biomolecular experimental study

   Författare :Fredrik Bryndahl; Annika Isberg; Lars Eriksson; Lars G Hollender; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescence; adverse growth; condylar cartilage; subchondral bone; TMJ; Radiology; Radiologi;

   Sammanfattning : The mandibular condyles represent important growth sites within the facial skeleton. Condylar growth is not a pacemaker of mandibular development, but it provides regional adaptive growth that is of considerable clinical significance, as the condyle’s upward and backward growth movement regulates the anteriorly and inferiorly directed displacement of the mandible as a whole.

3. 2. Radiography and bone scintigraphy in osteoarthritis of the knee: comparison with MR imaging

   Författare :Torsten Boegård; Lund Diagnostisk radiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; MR imaging; bone scintigraphy; osteophyte; joint space width; weight-bearing; radiograms; Knee joint; osteoarthritis; tomografi; medicinsk instrumentering;

   Sammanfattning : The aim was to compare radiography of the tibiofemoral joint (TFJ) and the patellofemoral joint (PFJ), as well as bone scinigraphy with MR imaging in middle-aged individuals with chronic knee pain in the format of a prospective study of knee osteoarthritis. Individuals aged 35-54 years with chronic knee pain were identified. LÄS MER

4. 3. Fixation of the cemented acetabular component in hip arthroplasty

   Författare :Gunnar Flivik; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; reumatologi; Surgery; Skelett; muscle system; rheumatology locomotion; Skeleton; Cement pressurization; Cement penetration; Acetabulum; Cancellous bone; muskelsystem; Total hip arthroplasty; RSA;

   Sammanfattning : In total hip arthroplasty cemented fixation of the acetabular component is a generally successful concept, but the rate of aseptic loosening and consequent revision surgery is still too high. One of the crucial factors for longterm implant survival is the initial fixation and stability. LÄS MER

5. 4. Internal fixation of femoral neck fractures

   Författare :Leif Hernefalk; Linköpings universitet; []
   Nyckelord :Femoral neck fracture; osteotomy; internal fixation; device; technical principles; scintimetry; radiography; biomechanics; malposition; malreduction; complications; bone necrosis; revascularization; segmental collapse; non-union; elderly; osteoporosis; MEDICINE; MEDICIN;

   Sammanfattning : The incidence of femoral neck fractures in elderly people is rising requiring large health care resources. Internal fixation of the fracture is the treatment of choice in Scandinavia, but in 20-40% of the cases a late complication such as a segmental collapse of the femoral head after initial bone necrosis, or a non-union of the fracture because of non-healing, will occur.

7. 5. Maturation-dependent normal and injury-induced changes in rabbit knee articular cartilage

   Författare :Xiaochun Wei; Leif Ryd; Linköpings universitet; []
   Nyckelord :rabbit; development; maturation; knee joint; articular cartilage; osteochondral defect; cartilage repair; joint fluid; subchondral bone volume fraction; proteoglycan fragment; transforming growth factor-ß; biomechanics; indentation; histology; hlstomorphometry; MEDICINE; MEDICIN;

   Sammanfattning : Cartilage injuries are common in sports, and may on the long term develop to osteoarthritis. Prosthetic joint replacement is not satisfactory for young active individuals with extended cartilage injuries in large weight-bearing joints. In these cases, a treatment is needed which reestablishes normal joint surfaces by biologic means. LÄS MER
