Diagnosis
This demographic is most commonly affected by interdigital neuromas, particularly due to certain types of footwear.
Who are females between the age of 40 and 60?
This noninvasive measure involves modifying footwear to reduce mechanical pressure on the interdigital neuroma.
What is footwear modification?
Interdigital neuromas are most commonly found in this location on the foot, as identified by both Drs. Morton and Durlacher
What is the third interspace?
This initial imaging modality is used to explore bone pathologies and general foot structure in the evaluation of interdigital neuroma.
What are plain film radiographs?
This common symptom of interdigital neuromas can be present in up to 80% of patients and is a key consideration in surgical treatment.
What is metatarsalgia?
This type of shoe wear may aggravate interdigital neuroma by compressing and restricting the intermetatarsal spaces
What are shoes with narrow toe boxes or high heels?
This type of therapy uses microsonic energy pulses, theorized to stimulate healing in interdigital neuroma cases.
What is extracorporeal shockwave therapy (ESWT)?
This percentage represents the high occurrence of having multiple neuromas at one time, according to a study by Valero et al.
What is 65.2%
This sign, indicating splaying of neighboring digits in the transverse plane, may be observed on weight-bearing films in cases of significant space-occupying lesions.
What is the "Sullivan Sign"?
First described by Gauthier in 1978, this procedure involves a sharp release of the deep transverse intermetatarsal ligament rather than a complete neurectomy.
What is nerve decompression?
This physical examination maneuver generates a click upon palpation of a neuroma, known as a 'Mulder click'
What is medial and lateral compression of the metatarsals?
This method of foot manipulation aims to reduce pain symptoms in interdigital neuroma patients through the distraction of the metatarsophalangeal joint.
What is manipulation and mobilization of the foot?
This anatomical feature is a contributing factor to the predilection of neuromas in the third interspace, involving a communication between branches of the medial and lateral plantar nerves
What is the communicating branch between the common digital branches of the medial and lateral plantar nerves?
This imaging tool is praised for its cost-effectiveness and real-time visualization of the enlarged nerve in suspected interdigital neuroma cases.
What is ultrasound?
This approach to surgical treatment of interdigital neuromas involves complete excision of the affected part of the interdigital nerve.
What is neurectomy?
This test, described as 'web space tenderness,' is noted for its high sensitivity in diagnosing interdigital neuroma
What is the finger squeeze test?
This invasive nonsurgical treatment offers symptomatic relief when noninvasive measures fail, often performed with various agents.
What is injection therapy?
This is the term for the outer layers of connective tissue encasing a complete nerve and its fascicles, which show fibrosis and thickening in a neuroma.
What are the epineurium and perineurium?
In MRI, interdigital neuromas often present as this shape and are low signal on T1- and T2-weighted sequences.
What is an ovoid or dumbbell-shaped mass?
This term describes the regrowth of a nerve in a disorganized manner after neurectomy, which can lead to painful outcomes.
What is an amputation neuroma?
In the context of interdigital neuroma, this imaging modality is particularly noted for its ability to enhance the detection of neuromas when patients are positioned in a specific way, as discussed in the chapter
What is MRI with patient positioning in the prone plantar flexed position?
This study outcome suggests that the effectiveness of certain injections for interdigital neuroma may depend on this characteristic of the lesion.
What is the size of the neuroma?
This study found no clear histological differences between nerves excised due to pain from neuromas and plantar nerves from autopsy specimens without neuroma pain, except for this noticeable difference
What is swelling in nerves excised due to pain?
This factor significantly affects the visualization of an interdigital neuroma in MRI studies, potentially enhancing detection.
What is patient positioning in the MRI tube (prone with the foot in a plantar flexed position)?
This surgical technique involves implanting the nerve stump into muscle to prevent painful neuroma formation post-neurectomy.
What is intramuscular implantation of the nerve stump?
