Do you suffer from Morton’s Neuroma? Podiatrists in East Fremantle at George St Podiatry can help you!
A Morton’s neuroma is a type of nerve entrapment or irritation. It is also referred to as interdigital neuroma or metatarsalgia. The 5 long bones that form the ball of the foot(metatarsals) have a nerve that runs between each of them. If the nerve is irritated a thickening or swelling can occur. This leads to nerve becoming compressed, causing symptoms such as pain, swelling and burning in the ball of the foot. The adjacent toes may experience numbness or tingling.
Morton’s Neuroma can affect adults of any age, however woman are affected more than men. Middle aged women who wear high heel shoes are the most commonly affected subjects. Whilst a Morton’s neuroma may develop between any of the metatarsals it is more common in the third interspace of the foot between the 3rd and 4th toes. In rare instances it is possible to have multiple Neuromas in the one foot.
Causes and contributing factors:
- Chronic trauma theory: increased pressure in the forefoot through high heel shoes, narrow toe-boxes or tight calf muscles
- Intermetatarsal bursitis theory: inflammation of the bursa between the metatarsal bones causes secondary thickening and increased pressure on the nerve
- Entrapment theory: the nerve is compressed between the plantar aspect of the foot and tight intrinsic ligament or muscular structures
- Mechanical hyper-pronation theory: excessive rolling in of the foot during walking causes hypermobilitiy in the forefoot
- Foot posture and natural bony alignment: those with close proximity between the metatarsal bones are subject to greater pressure on the nerve
Morton’s neuroma treatment includes:
- Footwear changes
- Padding and strapping
- Functional foot orthotics with neuroma pads/domes
- Stretching exercises and manipulations
- Cortisone injection
- Surgical: excision of the neural thickening
