Sixty-nine patients with congenital abnormality of the femur were reviewed. Their manifestation of femoral dysplasia ranged from an intact femur approximately 60 per cent of the length of the normal leg to a subtotal absence of the femur in which only the femoral condyles remained, often with a congenital fusion of the knee joint. Two groups were defined: Group I consisted of those with congeni...

The rotation element-The key to the function of the knee joint, and to its derangements, is the rotation of the tibia on the femur which occurs on flexion and extension movements. The knee is not a simple hinge joint. The opening and shutting of the front of the joint in the act of flexion and extension involves the tibia in a winding course set by the configuration of the medial condyle of the...

Palpomyia iberaensis n. sp., was collected by Malaise trap in the province of Corrientes, Argentina and its female and attached male genitalia are described and illustrated. The species is distinguished by the following combination of characters: females with dark brown legs except fore trochanter, basal 1/2 of fore femur, basal 2/3 of mid femur, fore and mid tibiae except extreme tip, yellowis...

Evidence has indicated that mesenchymal stem cells (MSCs) harvested with the Reamer/Irrigator/Aspirator (RIA) procedure exhibited an improved osteogenic differentiation capability compared with MSCs obtained by bone marrow aspiration from the iliac crest. In the present study, we hypothesized that the harvest procedure indeed influences the osteogenic activity of human MSCs more than the tissue...

OBJECTIVE This consecutive retrospective study was designed to analyze and to compare the efficacy and outcomes of anterior cervical discectomy and fusion (ACDF) using a fibular and femur allograft with anterior cervical plating. METHODS A total of 88 consecutive patients suffering from cervical degenerative disc disease (DDD) who were treated with ACDF from September 2007 to August 2010 were...

Currently available implants for osseointegration in transfemoral amputees are OPRA system and ISP System which shows many advantages over conventional socket fixation. To overcome the limiting issues like periprosthetic bone losses in osseointegration, a new design was developed. The analysis of both OPRA and New design was compared with a normal femur bone during daily activities. The results...

Risk factors for fracture of the neck of the femur are relatively well established, but those for fracture at other sites are little studied. In this large population study we explore the role of age, body mass index (BMI), and physical activity on the risk of fracture at seven sites in postmenopausal women. As part of the Million Women Study, 1,154,821 postmenopausal UK women with a mean age o...

Condyle of femur (F) and tibia (T) are key bony landmarks around the knee joint. The condyles contour extraction is the first key step towards: quantification of femorotibial (FT) joint space width (JSW), to assess FT joint space narrowing (JSN), to determine knee joint alignment angles and in defining the lateral and medial condyle radii. This paper aims to contour extraction of femur and tibi...

Bone surface strains were measured in cadaver femora during loading prior to and after resurfacing of the hip and total hip replacement using an uncemented, tapered femoral component. In vitro loading simulated the single-leg stance phase during walking. Strains were measured on the medial and the lateral sides of the proximal aspect and the mid-diaphysis of the femur. Bone surface strains foll...

BACKGROUND The reconstruction of femur defects following tumor resection remains a surgical challenge. The clinical outcome of free vascularized fibula graft (FVFG) reconstruction for massive femur defects of more than 10 cm that were secondary to skeletal tumor resection is reported. PATIENTS AND METHODS Six patients with a mean of 3.3 years follow-up were reviewed. Five patients received do...
