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

Ligament-Bone and Tendon-Bone Conditions - Bone Formation

The behaviour of the bone around the joint varies in differing arthritic conditions. In rheumatoid arthritis the inflammatory joint condition is linked with loss of bone and this contributes to the damage to the joint and the disability which ensues. However, in ankylosing spondylitis (AS) the inflammation is accompanied by the formation of new bone at the inflamed sites. This new bone forms at each insertion site, growing together in the spine to form bony bridges across the vertebrae, stiffening the spine in a poor position in some cases which can cause significant disability. Since inflammation usually breaks bone down this is difficult to understand.

New bone typically forms at normal ligament or tendon insertions as we get older, but in arthritis the inflammatory phase which erodes bone does settle and then bony spurs can form as the bone laying down phase occurs next in time. In the case of AS, if a bony formation phase follows the inflammatory phase, then suppressing the inflammatory phase with medication might accelerate the bony formation process, increasing the disability. AS patients may continue to fuse their joints even in the presence of new biological treatments but they may be shown to inhibit bone formation at the insertions and thereby reduce disability.

Good and Bad Lumbar Posture

Good and bad lumbar posture has often been decided on grounds that are not sufficiently scientific and future recommendations need to be based on solid research. Early research on the effects of different spinal postures indicated that maintaining a lumbar lordosis reduced the pressures inside the disc nucleus. This seemed fine until it was realised that these pressures were being transferred to the rear disc walls and the facet joints. As the facet joints are known to be frequent causes of low back pain and the nucleus of the disc is not a source of pain the idea that a lordosis is desirable in all circumstances does not stand up to examination.

Overall having some flexion in the spine is better in static positions whilst a slight lordotic posture is better when walking. Too much flexion interferes with the ability of the muscles of the back to protect the spine, so a moderate position should be taken between too much flexion and too much extension. The benefits of slight flexion are mirrored in the typical habits of people in postures, such as crossing the legs or putting a leg up on something at a bar, both actions which increase the flexion of the lumbar spine.
