When Walking Becomes a Pain

Osteophytes Acetabulum

For months Odi Hatburn (65) has been complaining about a radiating pain in her right hip that has kept her from her regular breakfast at Tiffany's in Chifley Square. Giufeng and Paul take a close look at her radiograph of the pelvis, concentrating on her right hip (Fig. 8.52). I Osteoarthritis of the Hip (Coxarthrosis) I Osteoarthritis of the Hip (Coxarthrosis) Fig. 8.53 Osseous protuberances (osteophytes) are seen extending from the acetabular convexity in osteoarthritis of the hip joint. The...

What is Your Diagnosis

Mtp Joint Podagra

Osteoarthritis of the hallux base joint The base joint of the big toe frequently suffers from degeneration because it is exposed to a lot of physical strain (Fig. 8.72). Osteo-phytes and sclerosis of the periarticular bone point in this direction. Osteoarthritis may, however, become more aggressive (erosive osteoarthritis) and present with clinical signs of inflammation as well. Rheumatoid arthritis (RA, see p. 147) Radiographic findings in RA of the foot resemble those in the hand (Fig. 8.73)....

Erosion Femoral Head

Joint can be bacterial or sterile or rheumatic. Initially a synovial effusion is seen associated with a demineralization of subchondral bone. The periarticular soft tissues are swollen. Eventually the cartilage is destroyed in the total circumference of the joint (concentrically, Fig. 8.55a). Reactive synovial proliferation undermines the cartilage in the periphery of the joint and the typical erosions result. Toward the final stage of the disease, the joint is ankylosed or fused, making any...

Medial Patellar Osteophytes Pictures

Fig. 8.65 a Loss of joint space width in the medial tibiofemoral joint compartment associated with osteophytes along the edge of the tibial plateau is pathognomonic for osteoarthritis OA due to a varus alignment of the lower extremity. The meniscal cartilage and hyaline cartilage covering the articulating bones is destroyed in the respective main weight-bearing zone. b A little osseous protuberance at the upper margin of the patella indicates patello-femoral osteoarthritis, which is often...

Avascular Necrosis AVN of the Femoral Head

Osteonecrosis The Femoral Head

Fig. 8.56a If you look closely at this femoral head you will notice the flattening of the head in the weight-bearing zone. A narrow subchondral stripe of decreased density is also seen in this area. There are no signs of joint degeneration the joint space width is normal. This configuration is characteristic of an osteonecrosis of the femoral head due to a vascular insufficiency. All weight bearing must be avoided at once. Fig. 8.56a If you look closely at this femoral head you will notice the...
