Allograft reconstruction of the distal humerus after resection of a breast solitary metastasis: eleven years follow-up.

Resection is a rare indication for the treatment of solitary skeletal metastasis (SSM), and provides an opportunity to cure the oncologic patient. Reconstruction after resection can imply a difficult problem depending on the size and the location of the metastasis. In the reported case, an en-bloc resection of a SSM of a breast cancer located in the distal humerus was performed in 1990. Reconstruction of the osteoarticular defect has been achieved with a massive allograft. At eleven years follow-up the patient remains free of illness and shows a good functional result. With the result obtained in the reported case, we suggest that osteoarticular allograft can be of considerable value for reconstruction after excision of SSM in the distal humerus, and that cure can be achieved with the radical resection of a SSM of breast cancer.

The use of proximal femoral allografts in revision total hip arthroplasty.

The implant of a proximal femoral structural allograft is one of the possibilities to restore circumferential defects of multiply revised total hip arthroplasties. A review of 7 patients who underwent proximal femoral reconstruction with an allograft-prosthesis composite to restore bone loss in revision hip replacements is presented. The average follow-up period was 50.2 months. Two patients developed an infection and in one case an instability of the prosthesis appeared. Incorporation in the remaining 5 cases was/achieved in an average period of 8.2 months. Neither fractures nor high rate of resorption appeared in our series. The majority of patients have improved in the functional assessment. Despite the rate of complications, structural femoral allografts can be used with success in this difficult challenge of reconstructing major segmental bone loss of the proximal femur in revision hip surgery.

The procurement team as a factor of bone allograft contamination.

We studied the effect of the procurement team on the risk of contamination in 270 large bone allografts retrieved from 53 non-living donors under strictly aseptic conditions.The overall contamination rate was 8.1%. When the procurement team was constituted by three or less members the contamination rate was 5.6%, while if there were four or more members the rate was 12.9%; this difference was significant in the statistical analysis.We conclude that a procurement team constituted by three or less trained members is a determinant factor in decreasing the bacterial contamination rate of bone allografts.

Behaviour of bone allografts in the advancement of the tibial tuberosity.

In order to determine the behaviour of bone allografts in the advancement of the tibial tuberosity, we studied retrospectively 134 knees belonging to 119 recipients of frozen bone allograft for the treatment of a symptomatic patellofemoral osteoarthrosis. All patients had a 1.2-1.5 cm tibial tuberosity advancement with a release of the lateral patellar retinacula and no other additional surgery. Total incorporation of grafts took place in 116 cases (86.6%); graft resorption appeared in 16 patients (11.9%)(total resorption 3, and partial resorption 13). No disease transmission has been detected. To avoid donor site morbidity associated with harvesting iliac crest, the use of frozen bone allograft is a good alternative in the advancement of the tibial tuberosity.

Use of bone allograft in tibial plateau fractures.

To determine the behaviour of bone allografts in the treatment of tibial plateau fractures, 20 recipients of frozen bone allograft for a depressed tibial plateau fracture were studied. Incorporation of grafts took place in all cases, and no complication secondary to the allograft use has been detected. To avoid donor site morbidity associated with harvesting iliac crest, the use of frozen bone allograft is a good alternative in the treatment of depressed tibial plateau fractures.

Bone allograft contamination in multiorgan and tissue donors.

Multiorgan and tissue donors offer a larger quantity and high quality of bone allograft that cannot be obtained from living donors. The risk of bone contamination must be borne in mind if secondary sterilization is not performed. The bacteriological cultures of 270 bone segments obtained from 53 multiorgan or tissue donors were analysed to study the relationship between previous organ and tissue procurements and bone retrieval contamination. We concluded that no significant differences in bacterial contamination percentage were found for each type of previous organ and tissue procurement, nor in the number of teams per donor.

Unusual locations of osteoarticular tuberculosis.

Tuberculosis continues to occur frequently in some underdeveloped regions. Bone and joint tuberculosis is less common than the pulmonary form. Fourteen cases of bone and joint tuberculosis in unusual locations are presented. Tuberculostatic treatment and surgical approach were associated in all the patients. In 6 cases an arthrodesis of the affected joint was carried out. A surgical debridement was done in 6 patients and a needle biopsy in 2 patients in order to obtain samples for pathology and bacteriology. Twelve of the 14 patients recovered. One patient who was affected by atlanto-axial tuberculosis died within the immediate postoperative period. A second one affected by the acquired immunodefiency syndrome died 4 months after surgery.

Septic arthritis of the shoulder due to Streptococcus agalactiae.

The authors report a case of septic arthritis of the shoulder-joint due to group B beta-hemolytic Streptococci (Streptococcus agalactiae) in a 63-year-old female patient. These germs are a major cause of meningitis and septicemia in newborns and pregnant women. In adults, men and nonpregnant women, they have been a rare cause of septic arthritis.

Bacteriological study of surgical knives: is the use of two blades necessary?

Scalpel blades used in 115 operations were studied bacteriologically. In each case the knife used for skin incision was discarded immediately after the incision and a fresh knife was used to complete the operation. The scalpel blades were cultured in enriched thioglycolate and incubated at 37 degrees C. Readings were taken at 24 and 48 h. From positive cultures, colonies were isolated directly in solid media, and the germ was identified using routine tests. Results showed that there was no bacteriological evidence to justify the use of different blades for skin incision and deep dissection.

Pubic osteolysis simulating a malignant lesion: case report.

A case of posttraumatic osteolysis of the pubic bone simulating a malignant lesion in a 55-year-old woman is reported. A review of the literature revealed that all reported cases occurred in post-menopausal women, associated with radiologic evidence of osteoporosis and a history of slight trauma. Biopsy was performed because of the possible malignant nature of the lesion, which should be suspected in all post-menopausal women with a destructive lesion of the pubic bone.
