Cam-
type femoroacetabular impingement
(FAI) is a known cause of groin pain and a condition that can give rise to osteoarthritis of the hip (1). Patients suffering from this condition are mainly young and experience pain when the hip is moved through internal rotation and adduction at 90° of hip flexion.
What does CAM stand for in cam impingement?
The first involves an excess of bone along the upper surface of the femoral head, known as a cam deformity (abbreviation for
camshaft
, which the shape of the femoral head and neck resembles).
What causes cam type FAI?
Cam: This type results from
a bony growth at the head of the femur
. In some cases, physical activity may cause this growth to occur. Pincer: Caused by extra bone growth in the hip socket, this growth often happens during a child’s development. Combined: Both the cam and pincer types of FAI are present.
How do you fix camera impingement?
- Resting the affected hip.
- Modifying your activities to avoid moving the joint in a way that causes pain.
- Exercising as recommended by your doctor or physical therapist to strengthen the muscles that support the hip.
Does Cam impingement need surgery?
Approximately 60% of patients with cam lesions can be treated successfully without surgery
. The mainstay of non-operative treatment of cam impingement is physical therapy.
Do you need surgery for hip impingement?
Patients diagnosed with hip impingement syndrome can preserve their hip joint through a combination of
nonsurgical and surgical treatment methods
. Surgery is often recommended if nonsurgical methods have failed to reduce symptoms.
Can a cam impingement grow back?
All PRO scores were significantly improved at 3 months compared with preoperative scores and, except for visual analog scale score, continued to show improvement at 2-year follow-up. Conclusion:
There was no recurrence of cam deformity at 2 years after
femoral neck osteoplasty for femoroacetabular impingement.
What does FAI pain feel like?
FAI usually feels like
a sharp pain deep in the groin area
or in the front of the hip. It worsens with athletic activities, or with prolonged sitting. As symptoms progress, the muscles surrounding the hip will fatigue and become very sore.
Can FAI be fixed without surgery?
Although studies of conservative treatment clinical outcomes for FAI are scarce, some authors have reported good results. We have observed that
some patients with FAI do well without surgical treatment
, but the role of surgery in FAI is unclear.
Are you born with FAI?
FAI is
caused by deformities in the femur, hip socket
or a combination of both. The condition may begin at birth (congenital) or may develop as a child grows (acquired). The condition appears to be caused by a combination of genetic and environmental factors.
How do you sleep with a FAI?
Eliminate sitting with legs crossed. Side sleepers:
sleep with pillow between your ankles and knees
. Avoid excessive hip flexion while sleeping.
What do you do if you have fai?
Surgical and Nonsurgical Intervention
Once FAI has been diagnosed, your orthopedic surgeon will recommend either a nonsurgical or surgical approach. In both cases, proper exercises to strengthen and support the joint will be crucial.
Does stretching help hip impingement?
While the hip impingement may be related to bone structure, the surrounding muscles can help or hinder movement and can reduce pain.
Muscle release along with stretching will provide
the best results.
How successful is FAI surgery?
Conclusions: Primary hip arthroscopy for patients with FAI had excellent clinical outcome scores at a minimum of two years of follow-up. The average time to achieve success postoperatively, as defined, was less than six months. Overall, the
success rate was 81.1%
, which was consistent with prior studies.
How long does FAI surgery take?
A hip arthroscopy involving labral/cartilage repair and FAI decompression usually takes
about two hours
. This is done as an outpatient surgery (go home the same day).
How common is FAI surgery?
FAI is frequently seen in athletes. One recent systematic review of North American patients undergoing surgery for FAI found that the average age at surgery was 28 years and there was a mild
female preponderance FAI at 55% of patients
(9).
