Learning objectives
This pictorial essay explores the causes of metatarsalgia which can be broadly categorised as follows:
Intermetatarsal bursitis
Mortons neuroma.
Degenrative Joint Disease Osteochondral lesion of 1st metatarsal head Osteoarthritis Freiberg infraction
Sesamoiditis Medial and Lateral
Trauma Soft tissue: Turf toe Osseous: Metatarsal stress response Fracture of proximal phalanx
Inflammatory Tensoynovitis of flexor tendons Inflammtory arthropathy /synovitis
Neoplastic lesions Fibroadenoma
We aim to review the important anatomical features,
clinical presentations and characteristic features on MRI.
Background
Forefoot pain is a debilitating clinical complaintand a common reason for specialist consultation (1,2).
There is often significant overlap between the various condtions affecting the forefoot in terms of symptoms and presentations.
As such,
clinical history and physical examination has limited accuracy in differentiating the various causes of forefoot pain.
Plain film andsonographic evaluation are commonly used in theinitial evaluation offorefoot pain.
Cross-sectional imaging,
however, provides vitaldetail required foraccurate diagnoses (2,3).
In particular MRI offers excellent contrast resolution and multiplanar capability,
providing exquisite detail of...

BURSAE
Anatomy:
Bursae are fluid-filled sacs located near tendons,
ligaments,
skin,
and muscles that prevent friction between moving structures.
There are multiple bursae located at the base of the metatarsals and between the metatarsal bones in the intermetatarsal spaces located in the forefoot.
Intermetatarsal Bursitis (IMB)
Inflammation of the intermetarsal bursae (bursitis) can occur following trauma or secondary to systemic diseases such as rheumatoid arthritis,
gout or local irritation (Morton's neuroma).
Severe bursitis results in distension of the bursa causing fore foot pain and splaying...
Conclusion
Forefoot pain is a non-specific symptom caused by a plethora of pathologic processes.
There is significant overlap between the signs and symptoms of forefoot pathology.
There is also a potential overlap in the imagng features of these conditions.
Given this conundrum both clinicians and musculoskeletal radiologists must work in tandem to achieve anaccurate diagnosis.
The majority of forefoot pain can be managed conservatively.
In problematic cases or those requiring intervention,
MRI is especially useful as a problem solving tool.
