Great Toe Pain: First Metatarsophalangeal Joint Fusion Has Excellent Outcomes
Fusion is the most popular way to address arthritis and end-stage deformities of the first metatarsophalangeal (MTP) joint, including bunions. Cleveland Clinic data demonstrate the success of the surgery across multiple locations, surgeons and causes of great toe pain.

Great toe pain is one of the most common complaints in patients presenting to a foot and ankle clinic. Approximately one in five people over the age of 50 will experience a bunion (hallux valgus) or arthritis of the first metatarsophalangeal (MTP) joint (hallux rigidus). With adults living longer and being more physically active into their 70s, complaints of painful arthritis and bunions will only increase.
Fusion is the most popular way to address end-stage deformities and arthritis of the first MTP joint. It is the gold standard for treating late stages of hallux rigidus, arthritic hallux valgus, geriatric hallux valgus, revision first ray surgeries and inflammatory arthropathies such as rheumatoid arthritis. It affords predictable pain relief, offers position maintenance, restores foot function and may provide good long-term outcomes compared to other surgical procedures. A review of the literature shows good to excellent outcomes across the board. Almost all studies report a greater than 90% fusion rate, with patient satisfaction greater than 80%.
Outcomes of first MTP joint fusion at Cleveland Clinic
The Outcomes Management and Evaluation (OME) system is a database of information prospectively collected for almost all orthopaedic procedures performed at Cleveland Clinic. Patients are enrolled on the day of surgery, when complete patient-reported outcome measures (PROMs) are collected along with surgeon-reported information about the specific procedure. PROMs also are collected six months and one year after surgery.
In 2016, we began collecting data on first MTP joint fusions. The database includes multiple surgeons (podiatrists and orthopaedic surgeons) and locations throughout Cleveland Clinic’s health system in Northeast Ohio.
Between August 2016 and May 2021, 756 patients underwent a first MTP joint fusion at our institution. Of these, we reviewed 406 (54%) patients who had a complete dataset (baseline PROMs, surgeon data and one-year PROMs). Our patient cohort included 317 women (78%), with an average age of 65 (age range: 54-71). Indications for surgery included hallux rigidus (N = 117), hallux valgus (N = 135), arthritic bunion (N = 116), hallux varus (N = 19) and other (N = 19).
The baseline Veterans RAND 12-Item Health Survey (VR-12) for physical health was 36.8 versus 43.3 at one year (P < .001), while the VR-12 for mental health remained similar at 53.4 to 52.7 (P = .115). All Foot and Ankle Outcome Score (FAOS) subscores (for pain, symptoms, activities of daily living [ADLs], sports/recreation and quality of life) had a statistically significant increase from baseline to one year after surgery.
Overall, patients do well after first MTP joint fusion and are happy with their results, as demonstrated in these two cases.
A healthy 52-year-old fitness instructor presented with bilateral hallux rigidus (Figure 1). She initially underwent arthrodesis of the left great toe. Two years later, the contralateral fusion was elected. Now she is at full unrestricted physical activity and pain-free with bilateral first MTP joint fusions (Figures 2-4).
A healthy 75-year-old female presented with bilateral great toe pain, worse on the left foot than the right (Figure 5). She reported that the pain was interfering with her ADLs, including walking for exercise. At four months after first MTP joint fusion on the left foot, she had no pain and had returned to all activities (Figures 6 and 7).
In conclusion, first MTP joint fusion is a reliable procedure that produces favorable outcomes in patients with various first MTP ailments. Our prospectively collected data have demonstrated that the surgery is successful across multiple locations, surgeons and diagnoses. Although implants for arthroplasty of the first MTP joint now are available, outcomes of first MTP fusion consistently are superior.
