Reverse Microfracture of the Hip Acetabulum: A Technique for the Wave Lesion.

The long-term efficacy of the treatment of chondral lesions is very important to prevent hip osteoarthritis. Microfracture, autologous chondrocyte transplantation, and direct chondral repair, among others, are techniques that have shown good results in some cases. We propose a technique to treat wave lesions through reverse microfracture, with bubble decompression and adherence of the natural scar from the detached cartilage.

Thrombosed aneurysm of saphenous vein coronary artery bypass grafting.

We describe the case of a male patient, aged 76 years, referred for cardiac investigation due to retrosternal chest pain and dyspnea. He had a history of acute myocardial infarction and angioplasties in the last 30 years, including a saphenous vein coronary artery bypass grafting (SVCABG). Echocardiogram showed hypoechoic oval formation near the right ventricle, suggesting a pericardial cyst.

Chronic recurrent multifocal osteomyelitis exhibiting predominance of periosteal reaction.

Chronic recurrent multifocal osteomyelitis is an idiopathic nonpyogenic autoinflammatory bone disorder involving multiple sites, with clinical progression persisting for more than 6 months and which may have episodes of remission and exacerbation in the long term. It represents up to 2-5% of the cases of osteomyelitis, with an approximate incidence of up to 4/1,000,000 individuals, and average age of disease onset estimated between 8-11 years, predominantly in females. The legs are the most affected, with a predilection for metaphyseal regions along the growth plate.
