The hip is the classic ball and socket joint. Typical pains are felt at the front, deep inside the joint and are often to do with the cartilage surface including arthritic changes (hip
arthritis) or the fibrous tissues around the joint like the labrum and bony impingement issues. These are felt as deep pinching type pains. Pains nearer the surface are commonly to do with the numerous tendons.
The side of the hip can be very sore to lay on and are to do with tendon problems as well as bursa issues around the hip bone itself. (Trochanteric Bursitis)
At the back are the big gluteal muscles and tendons which are stubborn sporting injuries as well as deeper nerve and muscle type problems sometimes related to the back and pelvis as well as the deeper muscles and the nerves that pass through this area.
It is suggested that hip pain is a ‘hangover from evolution’.
Dr Paul Monk, of the Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences, Oxford, took 300 ancient specimens from the Natural History Museum in London and Oxford, and the Smithsonian Institution in Washington to create a library of 3D models, and spot changes to the shapes of single bones over millions of years. The findings show that the so-called neck of the thigh bone grew broader to support the extra weight as we evolved. However, studies show that the thicker the neck of the thigh bone, the more likely it is that arthritis will develop.
Scientists say this is one potential reason why humans are susceptible to so much hip pain. But they say it is not all bad news – the right physiotherapy and working on maintaining a good posture can help mitigate some of the downsides of our design. Link here to Paul Monk.
