Physiotherapists in Ipswich treat many different conditions including the issues profiled below.

The Structure of Bone

Bone is one of the body.s connective tissue and its cells produce a firm and rigid framework to make the skeleton of the body. It has a good blood supply and is surrounded by nerve endings which are mostly in the soft tissues which enclose the bone. Two types of bone exist, cortical bone which exists in solid masses or sheets and trabecular bone which is a lattice like honeycomb of small bone struts. The mass of bone secreted is five to eight percent water and 60-70 percent Hydroxyapatite, which is composed mostly of calcium and phosphate. The rest of the bone is made up of collagen, a form of fibrous tissue.

The crystals of Hydroxyapatite mean that bone is hard and can withstand compressive stresses while the fibrous tissue reduced the brittleness and resists tension stresses. Bone is laid down in an arrangement of concentric cylinders with a central channel carrying the blood vessels and nerves. The osteocytes or bone maintaining cells lie between the layers of bone. The whole unit of the individual cylinder is known as a Haversian system or an osteon. The periosteum covers the outer surface of the bone, with a tougher outer layer and a cellular inner layer.

Meniscal Tears

Each knee has a pair of interesting structures inside it known as the menisci, more commonly called the knee cartilages. They are cartilaginous structures a bit like banked tracks and attached to the top of the tibia on each side of the knee. Their upper curves surfaces accommodate the large curved condyles of the end of the femur which otherwise would have to articulate solely with the flat upper tibial surface. The function of the menisci is not entirely clear but they may have to do with distributing synovial fluid around the joint, giving the brain feedback on where exactly the knee is during activities or easing force transmission across the joint as it fills in the gaps between the two joint surfaces.

During movements of the knee the large femoral condyles can pinch the menisci against the tibial surfaces and cause tears in the substance of the meniscus. A small tear from the outside of the structure can cause a flap which is called a .parrot beak. tear. If the tear is horizontal along the plane of the meniscus and does not reach the edge then a flap can be produced which is known as a .bucket handle. tear.
