BACKGROUND Atypical femoral fracture (AFF) has been high-lightened, because it was associated with the long-term use of bisphosphonate. Comparing western countries, the incidence rate of AFF was unclear in East Asian patients. Our purposes were to estimate the incidence rate of radiologically defined AFF in Korea, and to determine the association between occurrence of AFF and long-term use of b...

We assessed 882 patients presenting with a proximal femoral fracture by a new mobility score and by a mental test score, to determine which was of the most value in forecasting mortality at one year. Both scores gave a highly significant prediction, but the mobility score had a greater predictive value and is easier to perform.

Bony abnormalities of the femur can significantly complicate total hip arthroplasty both for the primary and revision operations. No standard nomenclature exists for the description of these femoral abnormalities. A classification system is presented to standardize nomenclature, assist in preoperative planning, and to assist in the reporting of these defects.

BACKGROUND Atypical femoral fractures (AFF) are a rare type of femoral stress fracture recently described, potentially associated with prolonged bisphosphonate therapy. Evidence-based recommendations regarding diagnosis and management of these fractures are scarce. The purpose of this study is to propose an algorithm for the diagnosis and management of AFF. METHODS We performed a PubMed searc...

Total hip arthroplasty (THA) in proximal femoral deformity represents a relatively uncommon challenge. Proximal femoral deformity is classified depending on the etiology and location and geometry of the deformity. Classification by etiology includes developmental processes, previous trauma, or previous surgery (osteotomy or THA). The latter, previous surgery, is the most common cause of femoral...

Patency of the femoral artery of infants and children who previously had percutaneous arterial catheterization at a weight of less than 25 kg was studied angiographically. During the study period, 118 patients had repeat arterial catheterization. 48 from the opposite leg. Femoral artery occlusion was found in four patients, while 44 of the 48 studied from the opposite leg had complete patency. ...

We describe a case of an atypical peri-prosthetic femoral fracture around an un-cemented total hip replacement in a 73 year-old patient, thought to be secondary to bisphosphonate use. The challenges associated with fixation of these fractures are demonstrated with a failed prophylactic fixation requiring complex revision surgery.

Placement of a central venous catheter (CVC) is a common procedure, often replaced by femoral vein cannulation. The overall complication rate is 12 - 15%. Loss of a complete guide wire into the circulation is a rare and preventable complication. Here we report a case of guide wire loss during femoral venous cannulation and literature review.

Proper component positioning is essential for successful total knee arthroplasty (TKA). Femoral component positioning presents a technical challenge when significant femoral deformity is present. Most commonly, an intramedullary guide is used to make an accurate distal femoral cut. However, in the presence of a significant femoral deformity, this is not a viable option.The use of clamshell oste...
