Closed injuries of the extensor hood of the lesser toes are rare and seldom reported in the literature. We present the case of a woman aged 25 years who presented to the orthopaedic fracture clinic with a 2-week history of pain in the left fifth toe and inability to extend following a ballet dancing session. Investigations showed no fracture on plain radiographs, but an ultrasound scan demonstrated rupture to the extensor hood of the little toe. Successful surgical repair of the extensor hood was performed, and the patient made a good recovery with return to dancing activities.

Background: This study investigated factors that may predict the need for Morton's neuroma (MN) to undergo further treatment within 2 years of a single ultrasound-guided corticosteroid injection.Methods: A retrospective study was undertaken over a three-year period. The data was stratified into two groups: Group A - did not receive further intervention and Group B - received further treatment. We investigated age, gender, neuroma size and presence of other forefoot pathology or ipsilateral neuromas.Results: 54 patients (57 feet) were reviewed. 29 feet (51%) required further treatment within 2 years (11 repeat injections, 18 surgical excisions). Binary logistic regression showed that larger neuromas (p = 0.011) and younger patients (p = 0.007) predicted the need for further intervention but not gender (p = 0.272). The distribution of concomitant forefoot pathology and ipsilateral neuromas were similar between the two groups.Conclusion: Size and age appear to be predictors for further treatment of MN within 2 years of corticosteroid injection.

Anomalous or accessory muscles in and around the foot and ankle have been reported in 8% of the population. Quadratus plantae muscle is one of the medial anomalous muscles in the foot and is a rare cause of heel pain or mass. This muscle has been implicated in tarsal tunnel syndrome. There is exiguous radiological description of quadratus plantae muscle in the literature. We present a case of quadratus plantae muscle presenting as a painful plantar mass and demonstrate its magnetic resonance imaging (MRI) characteristics. We have also reviewed the literature for other medial anomalous muscles around the ankle. This case report shows that MRI can help in establishing the cause of plantar mass and pain in clinically equivocal cases. Most importantly, correlation of imaging with patient's history and clinical examination can prevent unnecessary surgical intervention. The heightened anatomical awareness will assist a general or musculoskeletal radiologist to delineate these anomalous muscles as a cause of painful mass and help in overcoming a clinician's dilemma.
