First metatarsophalangeal (MTP) joint pain is a common presentation in clinical practice, often described by patients simply as “big toe pain.” While many cases are managed conservatively, it is important to recognise when symptoms represent more complex joint pathology requiring further assessment and potential escalation of care.
The causes of first MTP joint pain are varied. Early degenerative change (hallux limitus) and more advanced arthritis (hallux rigidus) are frequently encountered, but clinicians should also consider soft tissue pathology, sesamoid disorders, inflammatory arthropathies, and post-traumatic changes. Patients may present with pain on push-off, stiffness, swelling, or difficulty with footwear. In some cases, symptoms may be intermittent initially but progress over time.
Initial management should focus on activity modification, appropriate footwear, and addressing biomechanical contributors. Podiatry plays a key role in early assessment, including evaluation of joint function, gait, and load distribution. Where mechanical factors are more complex, orthotists can provide custom orthotic devices aimed at improving first ray function and reducing joint stress. Recognising the distinction between these roles helps ensure targeted and effective early intervention.
Referral should be considered where symptoms persist despite appropriate conservative measures, particularly where there is increasing stiffness, functional limitation, or pain impacting normal gait. Patients who are unable to tolerate normal footwear, or who report significant limitation in activity, may require further investigation.
Imaging can be useful in guiding management. Weight-bearing radiographs remain the first-line investigation to assess joint space narrowing, osteophyte formation, and overall alignment. Ultrasound or MRI may be considered where there is diagnostic uncertainty or suspicion of associated soft tissue pathology.
Multidisciplinary team (MDT) input is particularly valuable in complex or persistent cases. Collaboration between podiatry, orthotics, physiotherapy, radiology, and orthopaedic surgery allows for a comprehensive assessment and more coordinated management plan. This is especially relevant in the private sector, where structured MDT pathways may not always be readily available.
Referral for specialist opinion should be considered where conservative management has failed, where imaging demonstrates significant degenerative change, or where there is uncertainty regarding diagnosis. Surgical options may be appropriate in selected cases, particularly in patients with advanced arthritis or persistent symptoms affecting quality of life.
For clinicians, recognising the spectrum of pathology underlying first MTP joint pain and knowing when to escalate care is key to avoiding prolonged ineffective treatment. For patients, timely referral ensures access to appropriate investigation and a more structured, multidisciplinary approach to management.
