Orthopaedic surgeons continue to study this technique as well as the types of implants available. This technique with particular implants, orthopaedic surgeons are cautious to recommend it at this time due to reports of higher complication rates, unpredictable short- and long-term results, as well as difficulty with salvage procedures should the Or replacing one or both sides of the joint with metal or plastic parts, is intriguing due to the success orthopaedic surgeons have demonstrated with these procedures in the knee, hip, ankle, and other joints. This is a newer procedure and additional studies are needed to examine the results over time. In limited studies, it also has shown to be as effective as fusion in relieving pain, while preserving motion of the joint. The advantages of this procedure are that it requires less bone to be removed and it is theoretically easier than a failed joint replacement The operation does preserve some motion but is not as predictable for pain relief and may not restore the normal mechanics of the joint.Īlternatively, another technique uses a synthetic cartilage implant plug made out of polyvinyl alcohol as the spacer. This soft tissue can come from your foot, another part of your body, or even preparedĬadaver tissue. In one technique, a piece of soft tissue is used as the spacer in an attempt to resurface the joint. Interpositional arthroplasty is primarily performed in two ways. The two bones to minimize contact on either side of the joint. This procedure removes some of the damaged bone (similar to a cheilectomy) and places a spacer between Joint Resurfacing (Interpositional Arthroplasty)įor the patient with moderate to severe hallux rigidus who wants to avoid loss of motion, an interpositional arthroplasty may be an option. The major disadvantage is that it restricts movement of the big toe, although most patients can still be active. The main advantage of this procedure is that it is a permanent correction to reduce pain. In this procedure, the damaged cartilage is removed and the two bones are fixed together with screws and/or plates so they can grow together. This procedure is called arthrodesis or joint fusion. Patients can participate in physically strenuous activity such as running without pain.Īdvanced stages of hallux rigidus with severe joint damage are often treated by "welding" the big toe joint. The advantages of this procedure are that it maintains stability and motion, and preserves the joint itself. This procedure alsoĬan be combined with other bone cuts that change the position of the big toe and further relieve pressure at the top of the joint. Removing the bone spur allows more room for the toe to bend up and relieves pain caused when pushing off the toe. The type of surgery would be determined by the extent of arthritis and deformity of the toe.įor mild to moderate damage, removing some bone and the bone spur on top of the foot and big toe can be sufficient. If pain persists after the non-surgical treatments, surgical treatments will be considered. That limit motion at the MTP joint also can help.Īlthough these treatments may decrease the symptoms, they do not stop the condition from worsening. Shoes with a stiff sole, curved sole (rocker bottom), or both also may minimize joint pain. Avoiding thin-soled or higher-heeled shoes can minimize the pressure at the top of the joint. Platelet-rich plasma injections and similar injections into the joint are promising but vary in effectiveness.Ĭhanges in footwear also may help. A physician may suggest pain relievers and anti-inflammatory medicines and ice or heat packs to reduce pain. Non-surgical management is always the first option for treatment of hallux rigidus. These X-rays are best done with you standing and putting weight on your foot. X-rays may be taken to identify the extent of joint degeneration and to show the locationĪnd size of bone spurs. Your surgeon also will check your foot for evidence of bone spurs. Your foot and ankle orthopaedic surgeon will examine the MTP joint to see how much you are able to move and where the pain occurs. In many cases, the diagnosis of hallux rigidus can be made with a physical examination.
