Ultrastructural changes in synovium and cartilage in experimental hemarthrosis in dogs.
This paper reports electron-microscopic findings in synovium and cartilage in experimental hemarthrosis in dogs. The results are correlated with the total amount of glycosaminoglycans in the cartilage matrix, measured by the fixed-charge density method. Very early, changes are seen in the synoviocytes, similar to synovitis, and especially phagocytosis of iron-containing particles forming secondary lysosomes or siderosomes. Siderosomes are also a constant feature seen in the chondrocytes, together with changes in the rough endoplasmic reticulum and in the glycogen content, correlating with the changes in the ground substance.

The authors present an experimental study of 30 rats, in which human dura mater preserved in glycerin was used to repair gaps in the Achilles tendon. The animals were killed 8 weeks after the surgery and evaluated by gross and microscopic examination. The results showed that the dura mater did not cause foreign-body reactions or adhesions and was surrounded by concentric layers of fibroblasts and collagen fibers, suggesting that it could be employed as a substitute for damaged tendons.

Evidence for spirochetal origin of Sudeck's atrophy (algodystrophy, reflex sympathetic dystrophy).
Four female patients with Sudeck's atrophy (SA) were evaluated at our department. Sera of all patients were investigated for antibodies against Borrelia burgdorferi. ⋯ In one patient structures identical with B. burgdorferi could be detected on histological sections from the skin of the affected limb. Our data and those of other authors suggest that a spirochetal infection can be regarded as an important etiopathogenetic factor in the development of SA.

ReviewIncisional hernia through iliac crest defects. A report of three cases with a review of the literature.
Although the iliac crest is the most common site from which autogenous bone grafts are obtained, complications are surprisingly rare. One of these is incisional hernia through the resulting bony defect. ⋯ Elective repair of such hernias is advisable in order to avoid such complications. Attention to primary closure of bony iliac defects when complete is mandatory to prevent the occurrence of incisional hernia.

ReviewPost-traumatic osteomyelitis. Pathophysiology and management.
Osteomyelitis is one of the most severe complications that can arise following operative treatment of bone. It requires a long-term treatment. The patient can never be sure that it heals completely. ⋯ Stabilization is achieved by means of an external fixator. Once the fracture area has been cleaned, cancellous bone grafting is done once, twice, or even more frequently. For wound closure it is necessary to rotate muscle groups, to cover the bone with dermatomic skin, or to use microvascular flaps.(ABSTRACT TRUNCATED AT 250 WORDS)
