Description

DESCRIPTION

Technical field [0001] The present invention relates to traction devices of treatment for the hip joint area. More specifically, the invention is a device, which enables self-treatment of hip joint area.

Prior art [0002] Traction is an effective treatment used within orthopedic medicine to stretch and relieve pressure on the human skeleton, ligaments, muscles and nerves. Hip joint traction known as femoral and acetabular separation is used for pain relief in the hip joint, that for example derives from osteoarthritis, impingement, tightness in the muscles, joint stiffness, mobility loss and for pre-surgical mobilization.

[0003] Historically, traction has been used combining ropes and weights to apply enough force to achieve separation of the joint. Orthopedic physiotherapists are using manual traction of the joints as a common daily treatment alternative. The physiotherapist treatment involves pulling the patient's body parts in different angles achieving the traction and vacuum phenomena at the joint required. Unfortunately, physiotherapist or any third party assistance is not always available. Therefore, an opportunity to perform necessary traction by oneself is needed.

[0004] Some devices for performing traction of the joint without any third party assistance are known from prior art. For example, US5681272 discloses a portable traction device, which enables pelvic traction by a user for the self-application without the need for specialized equipment or third party assistance. Due to its large size and complex construction, the mentioned traction device is uncomfortable to carry and needs careful dedication while in use.

[0005] US 4,181,125 which is considered to the closest prior art document, discloses portable traction device comprising a sling 80 which during use is attached to the foot of the user. The sling 80 is connected through a rope 82 across pully 60 to a traction weight 86. To achieve a separation in the hip joint, a traction force of at least 400 N must be applied (see, Arvidsson I. (1990) The hip joint: forces needed for distraction and appearance of the vacuum phenomenon, pages 157-161 of Scand J Rehabil Med. 22(3)).

[0006] Known devices need third party assistance or large equipment, wherein careful mounting is necessary to apply correct traction force. A need for hip joint traction may be necessary anywhere, therefor, there is a need for compact, portable, safe and easy selftreatment traction device.

Brief description of the invention [0007] The present invention relates to a hip joint self-treatment device according to claim 1. The a self-treatment device may be used to manually perform traction of the hip joint (femoral-acetabular joint) by using leg strength and body weight. The device includes a solid ankle brace, which comprises a fastening strap and anchoring mechanism that is connected to the holding point, which can be a support plate or a door chink.

[0008] The hip joint self-treatment device provides an innovative way of achieving hip traction by using body strength and weight. Moreover, the invention is portable, as it for example, fits into a pocket, costs a fraction of the price of any existing product, enables correct traction force, which corresponds to the force of 450N that creates a femoral head/socket "spring" effect for easier separation and can be used without the need for third party assistance.

[0009] Hip joint self-treatment device is a new and innovative medical tool that will fill the unanswered market gap of no side-effect self-treatments of hip joint disorders and is an alternative to pain and inflammatory drugs.
