Diagnostic Approach for Fifth Toe Pain

Initial Assessment and Imaging

The American College of Radiology recommends radiography of the foot as the initial imaging study for evaluating toe pain, with a sensitivity for detecting toe fractures ranging from 80-100% 1, 2, 3
Evaluate for point tenderness, swelling, deformity, or skin changes in the affected toe, and assess weight-bearing ability and gait pattern 1, 2
Consider advanced imaging, such as MRI or CT, if radiographs are negative but clinical suspicion remains high, or if soft tissue injury is suspected 2, 4

For acute pain, radiography (X-ray) of the foot is the recommended first imaging study, with a standard three-view study (anteroposterior, oblique, and lateral) typically sufficient 1, 2
For chronic pain, radiography (X-ray) of the foot remains the recommended initial imaging study, useful for detecting osteoarthritis, stress fractures, and other bony abnormalities 5, 6
MRI may be indicated for suspected soft tissue pathology, such as Morton's neuroma or intermetatarsal bursitis, and ultrasound may be useful for detecting Morton's neuroma, intermetatarsal bursitis, or plantar plate tears 4, 6

Appropriate footwear with adequate width is essential for managing chronic conditions, and orthotic devices may help redistribute pressure and reduce pain 7
NSAIDs may be used for pain management and reducing inflammation, and referral should be considered for displaced fractures, open fractures or dislocations, or pain persisting despite 6-8 weeks of conservative treatment 2, 7
Referral is also indicated for suspicion of systemic disease causing toe pain, or need for advanced imaging or diagnostic testing 7

Overlooking small avulsion fractures on radiographs, and failing to obtain weightbearing views when indicated, can lead to misdiagnosis or delayed diagnosis 2
Underestimating the impact of proper footwear on symptom management, and missing foreign bodies in cases of penetrating trauma, can also lead to poor outcomes 2, 7
