Why is post-free distraction important?

If you are a patient who will be undergoing hip arthroscopy surgery, it is important to know that there are risks. At the start of the procedure, your leg will be put in traction with or without a post in your groin to achieve the desired position. Traction means that your hip will be distracted, or pulled away, from the socket enough for your surgeon to insert instruments, see the entire joint and perform any necessary treatment.3

In order to put a patient in traction to achieve distraction, most surgeons will utilize a table that has a post placed against your groin for counter-traction. Although this technique has been commonly used for many years, the post applies significant force to your groin, which could result in postoperative issues including numbness in the groin, nerve and/or soft tissue damage and even sexual dysfunction.1 These issues are usually minor and transient, but occasionally they may be more severe and permanent.

While these risks are well known in the medical community, patients, like you, may not always be fully aware of or prepared for these potential post-related problems, duration of the problems and how to manage them if you experience them.1 We want to provide you with this information as well as information on a post-free option.

Speak with your doctor and discuss the risks associated with hip arthroscopy surgery.

Important information about arthroscopy


Hip arthroscopy is performed in individuals to treat joint disease resulting from conditions such as femoroacetabular impingement, labral tears, removal of loose fragments of cartilage inside the joint, inflamed joint lining or painful bone spurs.

Hip arthroscopy surgery is often not considered to be appropriate for patients with certain types of infections, compromised bone stock, skeletal immaturity, severe arthritis of the joint or excessive body weight.

Like any surgery, hip arthroscopy surgery has serious risks which include, but are not limited to, pain, infection, bone fracture, peripheral neuropathies (nerve damage), circulatory compromise including deep vein thrombosis (blood clots in the legs), heart attack and death.

The information presented is for educational purposes only. Speak to your doctor to decide if hip arthroscopy surgery is appropriate for you. Individual results vary and not all patients will return to the same activity level. It is important to closely follow your doctor’s instructions regarding post-surgery activity, treatment and follow-up care.
