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.

Limb-preserving operations in the treatment of malignant bone tumors.
Limb-preserving resections require very careful indications; in particular, the criteria of oncologic radicality must be strictly considered. The functional results can be improved compared with those of ablative surgery, while the rate of relapse-free survival is the same. Surgical therapy for metastases of bone tumors should be performed by simple and safe procedures which allow for quick rehabilitation. The most important limb-preserving methods of operation in the treatment of primary and secondary malignant bone tumors are discussed and a few examples are presented.

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)

Factors associated with heterotopic bone formation following total hip replacement.
In order to delineate groups of patients suitable for treatment to prevent heterotopic bone formation (HBF) following total hip replacement, 99 patients were examined to evaluate predisposing factors. One year after surgery, HBF was found in 73% of the patients. ⋯ Previous ipsilateral hip surgery did not increase the risk of HBF. Although not significant, all patients who developed heterotopic bone after previous ipsi- or contralateral hip surgery showed HBF of the same or even a higher grade after the present replacement.
