“…In this study, the use of circumferential proximal femoral allograft showed satisfactory clinical results and 93.1% survival of reconstruction in an average follow-up of five years and two months. The most frequent complication was prosthetic dislocation (20.7%), which was also found in studies by other authors (3,16) . One limitation of this study is the small number of patients, but this type of femoral reconstruction is considered exceptional.…”

“…Those that most frequently require a new surgical procedure are infection, pseudarthrosis, allograft fracture, and instability. Furthermore, the use of homologous graft presents a potential risk of disease transmission, which is minimal with current methods of harvesting, processing, and storing of musculoskeletal tissues (16) . The incidence of infection, the most feared complication, can range from 3 (15) to 20% (17) of cases.…”

The authors declare that there was no conflict of interest in conducting this work ABSTRACTObjective: To evaluate the clinical and radiographic results from patients who underwent femoral reconstruction secondary to loosening of total hip arthroplasty, using circumferential proximal femoral allografts and cemented implants. Methods: A retrospective study was conducted on 32 patients (33 hips) who underwent femoral reconstruction secondary to loosening of total hip arthroplasty, using circumferential proximal femoral allografts and cemented implants. Among these patients, 28 (29 hips) fulfilled all the requirements for this study. The mean follow-up was five years and two months. The clinical evaluation was done in accordance with the Harris Hip Score. Radiographically, the patients were assessed regarding reabsorption and consolidation of the allograft, migration of the greater trochanter, stability of the femoral component and heterotypic calcification. Results: The average preoperative Harris Hip Score was 32 points. At the last postoperative follow-up, the average score was 82 points. Allograft resorption of some degree was seen in nine hips (31%). Regarding consolidation, 24 cases (82.8%) showed full consolidation, three (10.3%) showed partial consolidation and two (6.9%) showed pseudarthrosis. All femoral components were stable. According to the criteria established, 27 cases (93.1%) were considered to be successful reconstructions after a mean follow-up of five years and two months. Conclusion: From the results obtained, it was concluded that use of circumferential proximal femoral allografts in selected cases of femoral reconstruction secondary to loosening of arthroplasty presented a high survival rate from the reconstruction over an average follow-up of five years and two months.

“…However, few option can the current methods for harvesting, processing and storing musculoskeletal tissues (15) . Use of circumferential proximal femoral grafts allows correction of the hip abductor mechanism and leg length discrepancy, and also presents osteoconductive potential in that is enables gradual substitution by host bone, with consequent replacement of the bone stock (1)(2) .…”

“…Eugster et al (2004) reported that the incidence of infection post-surgery was associated with three factors: the duration of surgery, a large number of people moving within the operating room, and insufficient cleansing and disinfection of the operating room. Roos et al (2000) had insisted on the importance of the maintenance of local bone tissue banks, where orthopedic interventions could be performed. This is because of the numerous benefits of the procedures that require large quantities and different anatomical forms of preserved materials.…”

Bacteriological evaluation of bone grafts stored by cryogenic freezing at –24°C from a canine (Canis familiaris) bone bank

The scientific basis of bone transplantation was established during the mid-nineteenth century, when the osteogenic properties of the bone and periosteum, beneficial influence of cold preservation of bones, and first conventional attempt to store bones for elective use, were described. A bone bank has several advantages, such as the immediate availability of grafts in large quantities, and different shapes and sizes, and maintenance of osteoinductive activity in grafts. In addition, it reduces patient blood loss, surgical time, and quantity of anesthetics required. Clinical applications include the correction of comminuted fractures, treatment of non-union bones, and replacement of bone loss due to infections or malignancies. The success of these procedures depends on the preservation and integrity of the graft. This study aimed to evaluate the feasibility of maintaining a canine bone bank (Canis familiaris) by quantifying the bacterial contamination of bone grafts preserved at -24°C. The samples were evaluated through a monthly assessment of bacteriological cultures over a period of 6 months. The harvest method was efficient and sterile, reducing the risk of contamination. We conclude that the techniques chosen for the implementation of a bone bank were effective and feasible (use of a common freezer reaching a temperature below -24°C). The viability of the bones was attested during a 6-month period, and the samples demonstrated a 100% sterility rate.

As vantagens do banco de ossos são a disponibilidade imediata do enxerto em quantidade, forma e tamanhos variados, com a manutenção de sua atividade osteoindutora, e redução do tempo cirúrgico, anestésico e perda sanguínea do paciente. Dentre as aplicações clínicas cita-se a correção de fraturas cominutivas, tratamento de não união óssea e reposição de perda óssea devido a infecções ou neoplasias. O sucesso destes procedimentos depende dos parâmetros de conservação e integridade do enxerto. Este estudo teve como objetivo avaliar a viabilidade da manutenção de banco de ossos de cães (Canis familiaris) quantificando a contaminação bacteriológica dos enxertos ósseos, submetidos à técnica criogênica (-24°C) e avaliados através de realização mensal de culturas bacteriológicas por um período de seis meses. O método de coleta mostrou-se eficiente e propiciou adequada manutenção de esterilidade
