Most interdigital neuroma can be diagnosed clinically. But, diagnostic local injection method, sonography and magnetic resonance image(MRI) have been used as secondary tests for clinical confirmation or surgery. Recently, there have been active discussions on the method of interdigital neuroma diagnosis for which sonography or MRI is used. For finding out the location or the number of interdigital neuroma particularly in non-typical clinical manifestation or surgery, MRIs, which are exellent in tissue contrast, may be quite helpful. This case had an interdigital neuroma showing non-typical manifestation. MRIs were used for clinical diagnostic confirmation and finding out the location and the number of interdigital neuroma. Thus, the validity along with literary consideration is being reported.

Morton's neuroma has been treated with resection of the enlarged interdigital nerve by most of surgeons, but the numbness after resection could bother the patients. We reported the experiences of the good results after treatment of Morton's neuroma with the decompression of the interdigital nerve. Three patients, 4 feet were diagnosed to Morton's neuroma and taken the surgery, decompression of the interdigital nerve after the conservative treatments. The decompression can be considered first as another choice of treatment for interdigital neuroma before resection of the nerve.

Purpose: We examined the relationship of interdigital neuroma occurring site and the surrounding structures, including the deep transverse metatarsal ligament (DTML) by cadaver study and clinical results. Materials and Methods: Seventeen fresh frozen cadavers study were done to evaluate the relationship of interdigital neuroma occuring site and the DTML at two phase of the gait cycle with 60 degree of metatarsophalangeal dorsiflexion and with 15 degrees of ankle dorsiflexion. We measured the distance from interdigital nerve bifurcation of the common digital nerve to anterior margin of the DTML and longitudinal length of DTML itself. Clinically, we checked the location of interdigital neuroma and DTML length during surgery in 32 feet. Results: In the second and third web space, the mean distance from bifurcation of the common digital nerve of foot to the anterior margin of DTML was 16.7 mm, 15.1 mm in the mid-stance position, and 15.9 mm. 14.6 mm in heel-off position. Second, Third web space ligament itself length were average 12.8 mm, 10.6 mm. Clinically, all of the cases of interdigital neuroma started at the bifurcation area of the common digital nerve and interdigital neuroma was average 7.5 mm (range; 6-11 mm). Conclusion: Interdigital neuroma were located more distally than DTML in both the mid-stance and heel off stage. The main lesion was located between metatarsal head and metatarsophalangeal joint and more distal than the DTML anterior margin.

Purpose: To compare ultrasonographic size of morton's neuroma measured to actual size. Materials and Methods: Thirty-two (twenty-eight patients) of symptomic Morton's neuroma were measured by ultrasonography preoperatively and by manual method that designed by authors intraoperatively from January, 2002 to May, 2003. Two results were stastically compared by paired T-test. Results: Except one, all of cases were women and the mean age of patients was 50.6 years (32-62 years). The most common associated disease was hallux valgus deformity (17 cases). Six of Morton's neuromas located on second intermetatarsal space, sixteen of them did third intemetatarsal space and ten of neuromas located simultaneously second and third intermetatarsal space. The ultrasonographic size of neuroma averaged 3.48 mm and real size was 3.99 mm. The size checked by manual method was larger than by ultrasound with statical meaning. Conclusion: The size of Morton's interdigital neuroma checked by ultrasonography on plantar aspect is smaller than real size. If you checked Morton's interdigital neuroma size by ultrasonography, you can suspect that real size of Morton's interdigital neuroma is larger than that size.

Purpose: The purpose of this study is to evaluate the effectiveness of low-dose gabapentin for interdigital neuroma. Metrials and Methods: Between April 2000 and June 2003, 32 patients (39 feet) with interdigital neuroma were treated with using low-dose gabapentin. Two of the 32 patients were male, and thirty were female, and the average age was 47.4 years. The follow-up was 6 to 44months (mean 15.1 months). All cases were diagnosed by physical examination and ultrasonography or MRI. Low-dose gabapentin (300-600 mg) was prescribed and shoe modification was recommended. The patients were evaluated through questionnaire. Results: Neuroma was found in twenty one cases at the third intermetatarsal space, and thirteen at the second intermetatarsal space. The sensitivity of ultrasonography was 96% and that of MRI was 79%. Overall satisfaction was rated as excellent or good by 18 cases (57%). Average pain relief ratio was 50.3%, and in 14 cases, more than 80% of pain relief was noted. Nine (28%) of 32 patients showed they had no activity restrictions, such as daily activities or work, whereas 8 (25%) had mild restrictions and 15 (47%) had major restrictions. Twelve of 15 patient with major restrictions had been treated operatively (neurectomy; 10 cases, decompression; 2 cases). One case had gastrointestinal problem. Conclusion: Low-dose gabapentin for interdigital neuroma was one of the effective conservative treatments. The operation may be preserved for patient with the persist symptoms, nevertheless the conservative treatments and use of low-dose gabapentin.

전족부 통증의 주요 원인 중의 하나인 모턴씨 신경종, 즉 족지간 신경염은 진정한 종양이 아니라 신경 포착 증후군의 일종으로 이해되고 있으며, 진단 시 정확한 이학적 검사와 함께 전족부 통증의 원인이 되는 다른 질환과도 감별해야 한다. 치료에 있어서는 적절한 보존적 치료에도 증상 호전이 되지 않는 환자에게 수술적 치료로서 신경절제술이 주로 시행되어 약 80%의 환자가 만족하는 좋은 결과를 보고하고 있으나, 수술 후 만족스럽지 않은 결과를 보이는 2~35%의 환자를 적절히 처치함으로써 족지간 신경염의 치료 결과를 좀 더 만족스럽게 할 수 있을 것이다.

Purpose: The purpose of this study was to investigate the clinical results of conservative treatment for Morton's neuroma and to analyze the factors which influenced on the results. Materials and Methods: In this retrospective study, 101 cases of 83 patients with interdigital neuroma were conservatively treated with follow-up period of at least 6 months. There was no significant difference in results among different age groups, sxes, and lesion sites. However, the results were significantly better if the treatment was started within 6 months after onset. Results: We had 28 excellent results (28%), and 13 good results (13%). Patients were grouped by sex, age, duration of symptom before treatment, affected location. The result of treatment was evaluated by comparing the subject pain and discomfort score of the first vist and last follow-up. Conclusion: There are excellent results over 41% by conservative treatment. The results of conservative treatment were not related to age, sex, and lesion site, but were related to pre-treatment period. The shorter the pretreatment period was, the better the results.

Purpose: To evaluate the usefulness of ultrasound and MRI in diagnosing Morton's Neuroma, and the effect and significance of stepwise treatment. Materials and Methods: Out of all patients suspected of Morton's neuroma through history taking and physical examination, 77 patients (84 feet, 95 lesions) in whom Morton's neuroma was confirmed by ultrasound or MR imaging study or was clinically suspected with negative imaging studies, and followed up for over 3 months were included. In all cases, history taking and imaging study were done, and by comparison with operative findings of the patients, the sensitivity of ultrasound and MRI was checked. Postoperative evaluation was done using the AOFAS scale. The patient's satisfaction was also examined. Results: Morton's neuroma occurred most frequently at the $3^{rd}$ web space of the foot (56%), followed by the $2^{nd}$ web space (44%). Out of 15 cases suspected of morton's neuroma through ultrasound study, 13 were pathologically positive showing a sensitivity of 85.7%. Out of 16 cases suspected of morton's neuroma through MRI, 14 were pathologically positive showing a sensitivity of 83.3%. There was no significant difference in sensitivity between the two imaging modalities. Conclusion: In diagnosing Morton's neuroma, ultrasound examination had a similar sensitivity with MRI, therefore can be used as a screening study.
