[Women's role in Orthopedic Training programs: What Proportion Do They Represent Today?].

Introduction: The objective of the study was to analyze all orthopedics residency programs of Argentina and determine:1)The proportion of females; 2) Social and demographics differences between genders: 3) The factors that influence positively or negatively in female decision to choose orthopedics.

Method: An observational and descriptive study was carried out in two phases. First phase: analyze the database of the “Argentine Orthopedic Association during the period 2016-2017.

What Happens to the Articular Surface After Curettage for Epiphyseal Chondroblastoma? A Report on Functional Results, Arthritis, and Arthroplasty.

Background: Chondroblastoma is an uncommon, benign, but locally aggressive bone tumor that occurs in the apophyses or epiphyses of long bones, primarily in young patients. Although some are treated with large resections, aggressive curettage and bone grafting are more commonly performed to preserve the involved joint. Such intralesional resection may result in damage to the growth plate and articular cartilage, which can result in painful arthritis.

Proximal humeral osteoarticular allografts: technique, pearls and pitfalls, outcomes.

Allograft transplantation is a biologic reconstruction option for massive bone defects after resection of bone sarcomas. This type of reconstruction not only restores bone stock but it also allows us to reconstruct the joint anatomically. These factors are a major concern, especially in a young and active population.

Techniques in surgical navigation of extremity tumors: state of the art.

Image-guided surgical navigation allows the orthopedic oncologist to perform adequate tumor resection based on fused images (CT, MRI, PET). Although surgical navigation was first performed in spine and pelvis, recent reports have described the use of this technique in bone tumors located in the extremities. In long bones, this technique has moved from localization or percutaneous resection of benign tumors to complex bone tumor resections and guided reconstructions (allograft or endoprostheses).

What Are the Risk Factors and Management Options for Infection After Reconstruction With Massive Bone Allografts?

Background: Massive bone allografts have been used for limb salvage of bone tumor resections as an alternative to endoprosthesis, although they have different outcomes and risks. The use of massive bone allografts has been thought to be associated with a high risk for infection, and there is no general consensus on the management of this complication and final outcome. Because infection is such a devastating complication of limb salvage, at times leading to loss of a limb, recognizing the risk factors for infection and the results of treatment is important.

Intercalary femur allografts are an acceptable alternative after tumor resection.

Background: With the improved survival for patients with malignant bone tumors, there is a trend to reconstruct defects using biologic techniques. While the use of an intercalary allograft is an option, the procedures are technically demanding and it is unclear whether the complication rates and survival are similar to other approaches.

Questions/purposes: We evaluated survivorship, complications, and functional scores of patients after receiving intercalary femur segmental allografts.

Case report: Common femoral artery ligation after sarcoma resection in an infant.

Background: Vascular reconstruction in infants constitutes a surgical challenge and is indicated frequently for acute occlusions. With the presence of a subacute vascular occlusion, including that produced by tumor resection, collateral circulation develops quickly. Thus a surgeon can consider tumor and vessel resection, without the need for vascular reconstruction.
