According to Physiopedia, slipping rib syndrome can be diagnosed through a type of physical examination called the Hook maneuver. Additionally, observing the symmetry of the movements of the posterior chest wall during deep breathing may also determine if there is rib restriction.
Physiopedia explains that the Hook maneuver is performed by a therapist who hooks his fingers under the lower costal margin of the rib cage and pulls anteriorly, while the patient is lying on the unaffected side. If pain and clicking in the ribs are experienced while this test is being conducted, the patient might be suffering from slipping rib syndrome.
According to Physiopedia, slipping rib syndrome is characterized by pain in the upper part of the abdomen or lower portion of the chest, as well as a tender area on the costal margin, especially when it is pressed. This problem can be managed by performing manual therapy and by administering local anaesthetic nerve blocks and corticosteroids to the patient.
Physiopedia notes that therapy for slipping rib syndrome mainly involves manipulation of the patient's costovertebral joint to relieve pain. Furthermore, Physiopedia also states that removing the anterior end of the patient's rib and costal cartilage through surgery also produces positive outcomes.
