“…Intense tenderness elicited by pressure with the transducer over the suspected neuroma supports the diagnosis. In the appropriate clinical setting, US has a reported sensitivity of 95%-100% (30,31,36) for detection of Morton neuromas, with a specificity of 83% and accuracy of 95% (31). Similar results have been reported for MR imaging, which has demonstrated a sensitivity of 87%, specificity of 100%, and accuracy of 89% (37).…”

“…US evaluation can be performing by placing the probe on the dorsal (30,31) or plantar (32) aspect of the foot. For the dorsal approach, the toes are plantar flexed and manual pressure in the affected web space is applied on the plantar side.…”

“…Morton neuromas most frequently occur within the second or third interspace and are located at the level of or slightly proximal to the metatarsal heads. They appear as fusiform or ovoid hypoechoic masses elongated along the major axis of the metatarsals (30,32,34) (Fig 18). Beyond the tumor, the entering and exiting nerve may be slightly thickened and is therefore more easily identified than in normal subjects on longitudinal US scans.…”

US of Nerve Entrapments in Osteofibrous Tunnels of the Upper and Lower Limbs

The diagnosis of nerve entrapment at osteofibrous tunnels relies primarily on clinical and electrodiagnostic findings. Recently, the refinement of high-frequency broadband transducers with a range of 5-15 MHz, sophisticated focusing in the near field, and sensitive color and power Doppler technology have improved the ability to evaluate peripheral nerve entrapment in osteofibrous tunnels with ultrasonography (US). In the upper limb, osteofibrous tunnels amenable to US examination include the carpal tunnel for the median nerve and the cubital and Guyon tunnels for the ulnar nerve. In the lower limb, these tunnels include the fibular neck for the common peroneal nerve, the tarsal tunnel for the posterior tibial nerve, and the intermetatarsal spaces for the interdigital nerves. High-resolution US allows direct imaging of the involved nerves, as well as documentation of changes in nerve shape and echotexture that occur in compressive syndromes. A spectrum of extrinsic causes of entrapment, such as tenosynovitis, ganglia, soft-tissue tumors, bone and joint abnormalities, and anomalous muscles, can also be diagnosed with US. With continued experience, it is likely that this technique will be increasingly used to evaluate nerve entrapment syndromes.

“…Not infrequently, the diagnosis or the exact interdigital space involved is uncertain. Sonography is then of value in demonstrating a solid, hypoechoic soft tissue mass between the metatarsal heads, [22][23][24][25][26] although disappointing results have been reported. 27 I use a plantar sonographic approach in cases of suspected Morton's neuroma.…”

“…Injuries smaller than five millimeters may be difficult to visualize at the ultrasound test (1) . Ultrasound results prove that masses were found at the first space in 8% of the cases, at the second space in 44%, at the third in 46%, and at the fourth space in 2% of the cases (4) . Magnetic resonance is an imaging test that certainly shows the neuroma, its characteristics and size (5,6) .…”

Com o propósito de avaliar a eficácia da técnica cirúrgica - neurectomia por via plantar -, em portadores de neuroma de Morton, 19 pacientes foram submetidos a esse tratamento. Portanto, foram 19 neuromas, sendo 84,3% do sexo feminino, 15,7% do sexo masculino; 31,5% no segundo espaço intermetatarsal, 68,5% no terceiro; 47,3% no lado direito e 52,7% no esquerdo. A cirurgia foi realizada por via plantar em todos os casos, com tempo médio de acompanhamento de 9 meses, e o resultado foi considerado satisfatório em 89,5% dos pacientes. O tempo de retorno às atividades foi de 6 semanas em 84,2%. Dois pacientes se apresentaram insatisfeitos, ambos devido à dor residual abaixo da cicatriz. Os autores concluem que, a neurectomia por via plantar foi satisfatória, pois há uma melhor exposição do neuroma, boa cicatrização, retorno rápido às atividades e melhora da dor.
