Possibilities of revascularisation of the lower extremity through the deep femoral artery in elderly and aged patients with chronic critical limb ischemia were evaluated. Forty-nine patients with high surgical risk were studied. Safety of the extremity, decrease of ischemia degree and level of amputation were the main problems in surgical treatment. Deep-femoral-popliteal index was very important. If this index was less 0.3 surgeries on deep femoral artery were effective. If index was 0.3-0.5 results of surgery were questionable. Index more than 0.5 is the factor of unsuccessful revascularisation through the deep femoral artery.

Background: The number of patients with hip and femoral fractures is increasing and is expected to further increase in upcoming years due to the ageing population and the life expectancy of the general population. In this analysis, we aimed to systematically assess the post-operative complications associated with the pre-operative use of Aspirin in patients undergoing surgery for hip or femoral fracture.

As surgeons, we strive to recognize and correct any mistakes that may occur before completing an operation, and importantly, do our best to avoid irreversible mistakes. Over-resection of the femoral cam lesion in patients having hip arthroscopy for femoroacetabular impingement syndrome has been considered irreversible. While cam under-resection is a technical complication of femoroacetabular impingement surgery to be avoided, avoiding this at the expense of over-resection of the proximal femur is of great concern.

A 50-year-old female presented with a 10-day history of progressive swelling and pain in the left lower extremity, ultimately diagnosed with deep vein thrombosis (DVT) and May-Thurner Syndrome (MTS). Initial ultrasound indicated thrombosis involving the left external iliac, femoral, and popliteal veins, among others. Blood tests revealed normocytic anemia, but thrombophilia screening and other blood markers were normal.

Background Obesity is postulated to be a high-risk factor for thrombosis along with the inherent hypercoagulability of pregnancy. The Confidential Review of Maternal Deaths (CRMD) found that thrombosis was one of the major causes of maternal deaths in Kerala. This study investigates the major risk factor - obesity and its association with thrombosis in our study setting, along with other risk factors.

Objective: We sought to measure the deformation of tibiofemoral cartilage immediately following a 3-mile treadmill run, as well as the recovery of cartilage thickness the following day. To enable these measurements, we developed and validated deep learning models to automate tibiofemoral cartilage and bone segmentation from double-echo steady-state magnetic resonance imaging (MRI) scans.
Design: Eight asymptomatic male participants arrived at 7 a.
