What do I need to do if I experience symptoms associated with hip arthritis?
If you are experiencing any of the symptoms of arthritis of the hip and they do not clear after two weeks rest you need to visit your GP or manual therapist for a medical assessment.
What are the symptoms of arthritis of the hip?
Locking or clicking in the hip, pain in your hip or groin particularly while bending as if you were putting on a pair of socks. Stiffness or tightness in hip and noticeable loss in range of motion of the hip. Sometimes pain may refer to the knee, the buttocks or lower back.
Is it possible to make the hip joint unstable through excessive traction?
There is no evidence to suggest that the protocols prescribed with HipTrac would lead to extensive creep of ligaments of the hip joint causing it move beyond its physiological limitations. The ligaments around the hip joint are the strongest joint in the body. The forces required to cause extensive creep in these ligaments would have to be many times higher than HipTrac is able to deliver and applied for many hours a day for many years. Consider the creep forces applied to joints that have less strength. For example the cervical joints of the neck from a typical anteriorly shifted head. Or a thoracic spine that is slumped all day placing significant creep loads on the ligaments around the spine for many years. Joint instability is not the usual outcome in these examples. On the contrary muscle tightness and reduced mobility is the a more typical outcome here.
HipTrac provides long axis traction but what benefit is conferred for lateral and medial rotation of the hip?
It is possible to laterally and medially rotate the foot position before long axis traction force is applied and it is also possible to do traction in a side lying position. We are also developing devices that can be used in conjunction with the HipTrac to perform lateral traction.
What traction force can the HipTrac deliver?
HipTrac can deliver over 800N of force during traction, which is approximately 92PSI. Studies indicate that traction forces of 400 – 600N (46-69PSI) are required to deform the joint capsule.
How does HipTrac help with rehabilitation following arthroscopic surgical intervention for soft tissue repair or hip preservation surgery?
Following arthroscopic surgery there is significant damage to soft tissue caused by the keyhole surgery implements. This soft tissue needs to heal. HipTrac works to decrease the tightness and stretch these structures decreasing the pressure within and around the joint. Released tissue helps the healing process.
Post injection (e.g. Hyaluronic acid) should there be a rest time before using the HipTrac?
48-72 hours is most commonly advised by surgeons after injections for returning to normal activities in terms of treatment, manual therapy or exercise. You should seek advice from your health care provider.
Post arthroscopic surgical intervention should there be a rest time before using the HipTrac?
This will be patient specific and advice should be sought from your health care provider. Typically manual therapy begins 3 – 4 weeks following a procedure.
What research is planned for the HipTrac?
