Arthroscopic Decompression of a Popliteal Cyst

Background: Popliteal (Baker) cysts are enlarged gastrocnemius-semimembranosus bursae leading to swelling in the popliteal fossa.Surgical decompression and capsulectomy is the definitive treatment for symptomatic cysts with arthroscopic or open decompression.Arthroscopic decompression is minimally invasive, entails lower risks, and allows for earli

High chloride, sulphate and fluoride concentrations in clay-rich aquitard porewater, the North China Plain: evidence of geochemical behavior

The focus of this investigation was to constrain the porewater chemistry from tracer and ion profiles in a 128 m thick clay-rich sequence of Quaternary sediments comprising the clay, silt and fine sand formation in the North China Plain.Porewater are much more saline (1.1-71.0 g/L) than the lower confined groundwaters (0.3-1.3g/L).Chloride profiles
