Background. Morton's neuroma is the enlargement of an interdigital nerve most commonly located between the third and fourth metatarsals. It is susceptible to entrapment and therefore is a common cause of disabling foot pain. Greek foot is a normal variant where the first metatarsal is shorter than the second metatarsal. To our knowledge there is currently no reported association between Greek foot and Morton's neuroma in the literature. Material and methods. Retrospective study of 184 patients. Two separate cohorts were recruited. Cohort (A): 100 randomly selected patients with no foot pain. Cohort (B): 84 patients with foot pain and Mortons's neuroma. The foot shape was determined by using a self-assessment tool and plain radiographs. Statistical analyses were performed using the Chi square test on the association between Greek foot and Morton's neuroma. A value of P = < 0.05 was considered statistically significant. Results. Our study shows a statistically significant association between Greek foot and Morton's neuroma with a prevalence of Greek foot in Cohort (A) of 20% (95% C.I.:12%–28%) and in Cohort (B) of 63% (95% C.I.:53%–73%). (P = 2.6 × 10. −9. ). Discussion. This study has shown a possible association between the presence of a Greek foot and the presence of Morton's neuroma. We can conclude that people with foot pain are more likely to have Greek foot than Egyptian foot and that the prevalence of Greek foot is higher in patients with Morton's neuroma than in the asymptomatic population. Although our study design has limitations and does not allow full statistical analysis, we do believe that the shown association between Greek foot and Morton's neuroma can help clinicians and other health care providers in establishing the diagnosis of Morton's neuroma in patients with a painful foot

A Morton's neuroma is a compressive neuropathy most commonly affecting the common digital nerve of the third inter-space. Symptoms are variable but usually the diagnosis can be made quite easily and the diagnosis is essentially a “clinical” one. When symptoms relate to the second inter-space the clinician needs to be alert to mechanical causes of metatarsalgia leading to secondary irritation of the nerve. Imaging with MRI scanning and/or ultrasound can be helpful but equally can be misleading, as there may be false positives and false negatives. In the case of ultrasound the accuracy of imaging depends on the experience and expertise of the radiologist. Morton's neuroma surgery is usually associated with high levels of success but some reports suggest as many as 30% of patients under-going such surgery are dissatisfied with the outcome. The reasons for failed surgery can be broadly divided into three groups: a) wrong diagnosis b) wrong surgery and c) right diagnosis and right operation but unfavourable outcome. Wrong diagnosis is most commonly encountered in second space pathology when there is an underlying mechanical reason for the symptoms such as second MTP joint synovitis. This is usually secondary to joint overload associated with first ray insufficiency eg hallux valgus. This is the so-called Moron's neuroma. Wrong surgery occurs when the wrong space is operated upon, when mechanical causes are overlooked or when a plantar incision is made over the weight-bearing part of the forefoot, leading to painful scar formation. Wrong surgery can also involve failure to recognise anomalous anatomy within the space or insufficient nerve resection. Unfavourable outcomes include infection, stump neuroma formation or the onset of CRPS. Occasionally despite an appropriate assessment and operation a patient will derive no relief of symptoms and the cause of the pain remains totally unexplained. Careful history and examination and careful pre-operative planning can reduce the incidence of failed Morton's neuroma surgery. The role of imaging is probably greater in such cases compared with those presenting with a primary Morton's neuroma but the diagnosis remains essentially clinical. Stump neuroma resection should be considered in patients presenting with repeat symptoms especially if there is initial surgical success followed by recurrent symptoms. If two explorations result in no success then a third exploration is unlikely to resolve the problem. Some patients are left with intractable symptoms and should be referred to a pain specialist, as further surgery often has nothing more to offer

Background. Infiltration is considered the first treatment option for symptomatic Morton's neuroma and can be performed with various medications. The aim of this study was to compare the effects of hyaluronic acid infiltration versus corticosteroid injection in the treatment of Morton's neuroma. Methods. A randomised clinical trial was conducted with 46 patients (50 feet) diagnosed with Morton's neuroma. After randomisation, the control group (CG) received three injections (one per week) of triamcinolone (Triancil®) guided by ultrasound, while the study group (SG) received three applications of hyaluronic acid (Osteonil Plus®). Patients were followed up for six months after the intervention. The primary outcome measure used was the Visual Pain Analog Scale (VAS). Secondary endpoints included patient-reported outcome measures using the American Orthopaedic Foot & Ankle Society (AOFAS) score and complications. Results. Both groups showed significant improvement in VAS and AOFAS scores (p < 0.001). The CG showed greater improvement than the SG in the VAS (p < 0.05) and AOFAS (p < 0.001) variables. Four patients in the CG experienced skin hypochromia at the injection site, while there were no complications in the SG. Conclusion. Ultrasound-guided hyaluronic acid infiltration in Morton's Neuroma proved to be safe, showing improvement in pain and function after six months of follow-up, without major complications, but with a significantly lower improvement when compared to corticosteroid injection. Taking into account cost implications and the potential for longer lasting improvement from viscosupplementation further medium- and long-term studies are needed

Introduction. Morton's Neuroma is routinely treated by excision of the interdigital nerve. Traditional surgery works by denervation, but the results are variable, and recurrence is common. Multiple Morton's Neuromas present a difficult clinical challenge. MR and ultrasound often demonstrate a normal nerve or an interdigital bursa. Some experts advise division of the intermetatarsal ligament rather than excision. This case series evaluates an alternative method of treatment. Methods. Patients with a clinical diagnosis of Morton's Neuroma, with symptoms only on weight bearing, were treated with division of the intermetatarsal ligaments and Weil's osteotomies. The nerve was not excised. Patients wore a postoperative shoe for six weeks. If radiographs were satisfactory, they returned to weight bearing in a normal shoe. They were evaluated at 12 weeks with AOFAS scoring, as part of the routine clinical pathway. Results. 14 patients were treated with Weil's osteotomy, including one who had recurrence of symptoms following traditional surgery. The mean AOFAS score rose from 71 to 91. No patient had recurrent symptoms after surgery. The patient who had previously been treated with excision of the nerve also had some improvement. Discussion. The success of this surgery in relief of symptoms in this case series raises questions about the pathology, diagnosis and treatment of Morton's Neuroma. Many MR studies find abnormal nerves in asymptomatic patients, and no neuroma in symptomatic patients. Patients have symptoms exacerbated by weight bearing, and nerve compression may play an important part in the pathophysiology. Weil's osteotomy works by decreasing the effective weight bearing in the involved rays. It is particularly useful if symptoms exist in multiple intermetatarsal areas. Conclusions. Multiple Weil's osteotomies are an effective method for treatment of Morton's Neuroma. The basis for the traditional approach of excision of the nerve may be flawed and merits further study

Purpose: To describe sonographic evaluation of Morton’s neuroma and to demonstrate the advantage of the ultrasound technique. Material and methods: Between the years 1999–2001, eight patients were operated upon because of Morton’s neuroma in the 3rd interspace, using dorsal approach at the Basel Height Medical Center. Five patients were female and three were male, mean age 35 years (range, 17–51 years). All the patients suffered from metatarsalgia at the 3rd web while walking with shoes. No pain was noted when they walked barefoot. All the patients underwent sonographic evaluation by using high frequency transducers of 10 and 12 MHz. Plantar and dorsal scanning was performed with and without digital pressure of the metatarsal space. Results: In all the operated cases ultrasound examination prior to surgery revealed an ovoid, well defined hypoecogenic mass of a mean diameter of 8 mm (range 7–15 mm), located in the third interdigital space, proximal to the metatarsal heads. Plantar scanning and dorsal digital pressure, by the examiner, disclosed the best sonographic images. All cases were confirmed by histological examination. No surgical complications were noted. Conclusion: We present the sonographic appearance of Morton’s neuroma in eight cases that underwent surgical excision of the neuromas. We describe manual maneuvers in order to bring up the best images of the mass

The aim of our study was to compare the clinical versus radiological diagnosis of patients suffering from a Morton's neuroma. Clinical assessments and pre operative radiological imaging of patients who underwent operative procedures for an excision of a Morton's neuroma were retrospectively compared. This review included 43 excised Morton's neuromas from 36 different patients over a period of 68 months, performed by one surgical team. The commonest clinical symptoms were those of pain or tingling on the plantar aspect of the affected webspace on direct palpation (100%), pain of weight bearing (91%) which was relieved by rest (81%) and pain on stretching the toes (79%). The most sensitive clinical sign was a Mulder's click. Our results showed that clinical assessment was the most sensitive method of diagnosing these neuromas (98%). All of our patients had at least one mode of radiological investigation. Ultrasonography was the commonest requested single imaging modality in our series. It was found to have a sensitivity of 90% (28/31). This imaging technique has the disadvantage of being operator dependant, as highlighted by the fact that one of our patients had a correct radiological diagnosis after a repeat ultrasound to the affected area was requested. Magnetic Resonance Image scan is a more expensive technique as it has the advantage of producing static reproducible images. As a single imaging modality, it was found to have a sensitivity of 92% (12/13) in our series. 3 patients had both imaging modalities; initial ultrasound failed to convincingly diagnose a neuroma in 2 cases and in the other case, the initial MRI did not show any pathology. In all these cases, the repeat imaging techniques confirmed the clinical diagnosis. We conclude that there is no absolute requirement for ultrasonography or magnetic resonance imaging in patients who clinically are suspected to have a Morton's neuroma, as the clinical examination was found to be the most sensitive method of diagnosis. We suggest that the two main indications for performing some form of imaging is (a) an unclear clinical assessment and (b) cases when more than one webspace appears to be affected. An ultrasound of the webspaces should be the radiological investigation of choice, followed by a magnetic resonance scanning if any uncertainty still remains

Background: Morton’s Neuroma is most likely a mechanically induced degenerative neuropathy, presenting as forefoot pain. Methods: The authors retrospectively reviewed clinical notes, imaging and histology from 71 consecutive patients (75 feet) treated operatively for Morton’s Neuroma between January 2006 and April 2009 and a control group of 20 patients (20 feet) undergoing MRI for other forefoot pathology. 7 feet were excluded from the surgical group due to recurrent disease or missing data. Results: 84% of the surgical group were female. Mean age was 52. 97.4% of the surgical group presented with pain. 50% described pain in the plantar aspect of the forefoot and 85% reported that their pain was worse in shoes. Web space tenderness was positive in 95%, foot squeeze test 88%, plantar percussion 61% and toe tip sensation deficit 67%. Any two tests were positive in 92% of this group. In the control group any two tests were positive in only 39% – this difference was statistically significant (p< 0.0001 chi-squared test). MRI identified a neuroma in 97% of the surgical group (mean size 8mm) and 50% of the control group (mean size 6mm). 68% were in the 3rd web space; the remainder were in the 2nd web space. Histology confirmed neuroma in 99%. Discussion: This cohort is larger than any other published series and is further strengthened by both the consistency of clinical testing and the independence of radiological and histological assessment. Conclusion: We found that diagnosis of Morton’s neuroma was accurate. MRI correctly identified the neuromata in 97% and at least two clinical tests were present in 92%

Current knowledge regarding outcomes following surgical treatment of Morton's neuroma remains incomplete. This is the first prospective study to report the pre- and post-operative patient reported outcomes and satisfaction scores following excision of interdigital Morton's neuroma. Over a seven year period, 99 consecutive patients (112 feet) undergoing surgical excision of Morton's neuroma were prospectively studied. 78 patients were female with a mean age at operation of 56 years. Patient recorded outcomes and satisfaction were measured using the Manchester-Oxford Foot Questionnaire (MOXFQ), Short Form-12 (SF12) and a supplementary patient satisfaction survey three months pre and six months post-operatively. Statistically significant differences were found between the mean pre- and post-operative MOXFQ and physical component of the SF-12 (p< 0.05). No difference in outcome was identified in patients in whom multiple neuromas were operated compared to single site surgery. However, revision surgery proved to statistically worsen MOXFQ outcomes post-operatively p< 0.004. Overall satisfaction was reported as excellent (49%) or good (29%) by the majority of patients but 10% were dissatisfied with poor (8%) or very poor (2%) results expressed. Only 64% were pain free at the time of follow-up and 8% of patients MOXFQ scores worsened. These findings illustrate that overall, patient reported outcomes following resection of symptomatic Morton's neuroma are acceptable but may not be as favourable as earlier studies suggest. Caution should be taken when considering revision surgery which has shown to be a poor prognostic indicator. Contrary to current knowledge, multiple site surgery can be safely undertaken

Patient reported outcomes and satisfaction scores following excision of interdigital Morton's neuroma have been recently established. However, little is known regarding what patient factors affect these outcomes. This is the first and largest prospective study to determine which patient factors influence surgical outcome following Morton's neuroma excision. Over a seven-year period, 99 consecutive patients (112 feet) undergoing surgical excision of Morton's neuroma were prospectively studied. 78 patients were female with a mean age at operation of 56 years. Patient recorded outcomes and satisfaction were measured using the Manchester-Oxford Foot Questionnaire (MOXFQ), Short Form-12 (SF12) and a supplementary patient satisfaction survey three months pre and six months post-operatively. Patient demographics were recorded in addition to co-morbidities, deprivation, associated neuroma excision and other forefoot surgery. Obesity, deprivation and revision surgery proved to statistically worsen MOXFQ outcomes post-operatively (p=0.005, p=0.002 and p=0.004 respectively). Deprivation significantly worsened the mental component of the SF12 (p=0.043) and depression the physical component (p=0.026). No difference in outcome was identified for age, sex, time from diagnosis to surgery, multiple neuroma excision and other forefoot surgeries. 23.5percnt; of deprived patients were dissatisfied with their surgery compared to 7percnt; of the remaining cohort. Patient reported outcomes following resection of symptomatic Morton's neuroma are shown to be less favourable in those patients who display characteristics of obesity, depression, deprivation and in those who undertake revision neuroma resection. Surgery can be safely delayed, as time to surgery from diagnosis bears no impact on clinical outcome

The cause of intermetatarsal neuromas is unclear even if there is a mechanically induced degenerative neuropathy of the intermetatarsal nerve. Treatment of Morton’s neuroma includes conservative methods such as steroid or local anaesthetic injection, orthotic devices and surgical therapy. Surgical therapy has a reported failure rate of between 7% and 24%, depending on the case histories. Dockery in 1999 and Masala et al. in 2001 presented their results on alcoholisation of Morton’s neuroma. The aim of this study is to prove the reproducibility of the aforementioned procedure and its results. Between December 2001 and March 2004, 30 patients with Morton’s neuroma were examined with US and treated with alcohol injections under US guidance by the same operator. Among these 23 were women and seven men with age ranging between 37 and 70 years. Fifteen patients presented with more than one neuroma in the same foot or in both feet. The standard US was followed by a 3D US in order to extend the diagnosis in treated patients. Alcohol-sclerosing intralesional treatment was performed in 45 neuromas. The treatment consists of an injection cycle (minimum 1, maximum 4), composed of 50% ethyl alcohol (95%) and 50% of a 2% aqueous solution of carbocaine. A total of 90 injections were performed, with an average of two for each neuroma. The patients were examined after the treatment by both authors. On 31 (69%) neuromas, the alcohol-sclerosing intralesional treatment was successful; 14 (31%) neuromas had only a partial improvement and therefore the patients underwent a surgical excision. No procedure-related complications were observed. The results of this study indicate that, even considering the failure rate, compared to surgery the alcoholisation treatment of neuroma under US guidance is a valuable conservative procedure because of its low morbidity and cost-effectiveness. Alcoholisation under US guidance thus could be a useful tool for orthopaedic surgeons in order to determine whether surgical excision is really necessary

Background. The aim of this prospective study was to assess the effectiveness of a single ultrasound-guided steroids injection in the treatment of Morton's neuromas and whether the response to injection correlates with the size of neuroma. Methods. Forty three patients with clinical features of Morton's neuroma underwent ultrasound scan assessment. Once the lesion was confirmed in the relevant web space, a single corticosteroids injection was given using 40 mg Methylprednisolone along with 1% Lidocaine. All scans and injections were performed by a single musculoskeletal radiologist. Patients were divided into two groups based on the size of the lesion measured on the scan. Group 1 included patients with neuromas of 5mm or less and Group 2 patients had neuromas larger than 5mm. The Visual Analogue Scale (Scale:0 to 10), the American Orthopaedic Foot and Ankle Society score (AOFAS) and the Johnson satisfaction scale were used to assess patients prior to injection and then at 6 weeks, 6 months and 12 months following the injection. Results. Thirty nine patients had confirmed neuromas. Group 1 (lesion ≤5mm) included 17 patients (mean age, 30 years) (7 males, 10 females) and Group 2 (lesion >5mm) had 22 patients (mean age, 33 years) (8 males, 14 females). VAS scores, AOFAS scores and Johnson scale improved significantly in both groups at 6 weeks (p < 0.0001). At 6 months post-injection, this improvement remained significant only in group 1 with regards to all scores (p < 0.001). At 12 months, there was no difference between both groups and outcome scores nearly approached pre-injection scores. The need for surgical treatment for persistent symptoms was similar in both groups (p = 0.6). Conclusion. A single ultrasound-guided corticosteroids injection offers generally a short-term pain relief for symptomatic Morton's neuromas. The effectiveness of the injection is likely to be more significant and long-lasting for lesions smaller than 5mm

Introduction: Morton’s neuroma is a common cause of foot pain. For this study, we assessed the efficacy of a series of sonographically guided alcohol injections into the lesion. Method: One hundred and one consecutive patients with Morton’s neuroma were included in this prospective series. An average of 4.1 treatments per person wee administered, and follow-up images were obtained at a mean of 21.1 months after the last treatment (range, 13–34 months). Results: Technical success was 100%. Partial or total symptom improvement was reported by 94% of the patients, with 84% becoming totally pain-free. The median visual assessed pain score decreased from 8 before treatment to 0 after treatment (p< 0.001). Transitory increased local pain occurred in 17 cases (16.8%). There were no major complications. Thirty patients underwent sonography at 6 months after the last injection and showed a 30% decrease in the size of the neuroma. Discussion and Conclusion: We conclude that alcohol injection of Morton’s neuroma has a high success rate and is well tolerated. The success rate is acceptable at 84% whilst being associated with a low morbidity. The treatment avoids surgery and allows continued mobility with patients being able to weight bear and perform their usual activities of daily living. We advocate reserving surgical management for non-responders

Introduction: The first line treatment in our centre for Morton’s neuroma (MN), sufficient to warrant intervention, is a peri-neural Ultrasound guided injection of corticosteroid (USI). The NHS will soon implement 18 week referral to treatment targets. A prospective study was performed whereby from 2004–6, referral letters from General Practitioners suggesting a diagnosis specifically of Morton’s neuroma, resulted in randomised assignment to either direct referral for USI or to the specialist Foot and Ankle outpatient clinic. Patients with less specific referral letters were evaluated in clinic and referred for USI as appropriate. A comparison was made of the sensitivity and specificity of the referral pathways, financial implications and the time to treatment (TTT). Results: 121 patients were referred for USI. Of 57 patients for whom the GP had diagnosed a MN, 40 (70%) had the diagnosis confirmed on USI (other diagnoses were: 7 NAD, 3 ganglions, 2 bursae, 2 degenerative change, 1 glomus tumour, 1 angioleiomyoma, 1 SOL); this was comparable to the overall number referred to radiology with a suspected MN (69%). In the directly referred group, the mean TTT was 115 days (95%CI = 89 – 141), compared to 241 days (95%CI = 223 – 259) for those patients who went via a Foot and Ankle clinic. P< 0.0001. Conclusion: For patients with features highly suggestive of a Morton’s neuroma, direct referral from primary care for USI has a similar sensitivity and specificity to referral from a specialist hospital clinic and the TTT is significantly shorter. The mean wait of this group is within the 18 week government target without any changes to our current radiology protocols. Using this direct referral protocol we saved 29 outpatient appointments; if followed for all eligible patients we would have saved 57 outpatient appointments

Data was collected for patients referred to the orthopaedic department at Forth Valley Royal Hospital with metatarsalgia who subsequently received an ultrasound. Patients found to have a Morton's neuroma were divided into groups based on its size. A total of 90 patients received an ultrasound scan and neuroma was confirmed in 58 with an alternative diagnosis found in 32 patients and a total of 42 were included in the final analysis. All 14 patients with neuroma < 6mm reported resolution of symptoms. 4 (28.5%) underwent surgical excision as first line, 1 (7%) received a single corticosteroid injection and 9 (64%) were treated with metatarsal bars. There were 27 patients with neuroma > 6mm; 8 (29.6%) underwent surgical excision as first line treatment, 5 (18.5%) received metatarsal bars and 14 (51.9%) received injections. 7 (25.9%) patients reported resolution of symptoms after 1 injection, 1 (3.7%) patient required 2 injections and 1 (3.7%) patient required 3 injections to achieve resolution. 5 (18.5%) patients required surgical excision following ongoing symptoms despite non-surgical treatment. 9 (33.3%) reported resolution of symptoms following injection. 5 (18.5%) reported resolution of symptoms following use of metatarsal bars. A total of 71% of patients with a neuroma measuring < 6mm reported full resolution of symptoms with non-surgical treatment. For patients with neuroma >6mm, 64.3% had resolution of symptoms with injections alone and 18.5% required surgical excision despite injection. In conclusion, there is a benefit to offering non-surgical treatment as first line in patients with a neuroma regardless of size

A prospective study of 72 patients with Morton’s neuroma was carried out outlining presenting symptoms, significance of clinical examination and the beneficial effect of various treatment modalities. They were followed up for at least 6 weeks. There were 51 females (70%) and 21 males (30%) with average age of 52 years. Bilateral symptoms were present in 15% cases with remaining 85% cases having unilateral symptoms. Commonest symptom observed was pain in the web space, commonest being 3. rd. space (70%) and others being 2. nd. space (18%), 4. th. space (4%) and combination of two spaces (8%). In 90% of these cases, pain was aggravated by walking and wearing closed shoes; and relieved by taking rest. Paraesthesia in adjacent toes was present in 46% cases. Clinically palpable Mulder’s click was seen in 54% cases. Shoe modification was tried in 33% patients, with little benefit. All 72 patients underwent corticosteroid and local anaesthetic injection in the outpatient clinic. Fair to good pain relief was obtained in 76% cases with average duration of pain relief of 2.8 weeks (range (0–8 weeks)). No pain relief was achieved in 24% cases. Twenty-eight patients (38%) who either had inadequate pain relief at 6 weeks following injection; or had recurrence of pain eventually underwent surgical excision/decompression using plantar approach. None of them had any complication related to surgery. All patients had excellent pain relief at a minimum of 6 months follow up after the surgery. 90 % of the patients who underwent surgery had VAS pain score of 0 at 6 months follow up. Thus, single injection treatment is a very useful treatment modality achieving satisfactory results in 76% of patients. Surgical excision/decompression should be reserved for patients with no pain relief/recurrence after the injection

Background. Morton's neuroma (MN) is a common cause of metatarsalgia. Whilst there are a many treatment modalities available, studies looking at the long term effectiveness of most forms of treatment are scarce. The injection of MN with alcohol has gained popularity over the past ten years with widespread media coverage. Many surgeons have anecdotally questioned the long-term effectiveness. Sixty patients underwent alcohol injection for the treatment of MN by Radiologists at our institution. These results were originally published showing 92% (92/100) success rates and only 3% (3/100) requiring surgical excision at a mean follow up of 10.5 mths. The authors concluded that alcohol injection was comparable to results for surgical excision. Methods. We were able to review forty five of this original cohort with an average follow up of 61 (range, 33 to 73) months. The modified Johnson score and visual analogue scales were used to assess the patients and compare these results to five year results available in the literature for surgical management. Results. Our results indicated that by five years 36% (16/45) had undergone surgical treatment and a further 45% (13/29) had return of symptoms. Only 29% (13/45) remained symptom free. Results at five years showed statistically significant differences (P< 0.05) compared to surgical management, with 67.8% complete resolution of symptoms with surgery and 33% in the alcohol injection group. Conclusion. Injection with alcohol sclerosant for MN has been marketed as a definitive management option comparable to surgical excision. Our investigation illustrated that although short term results are encouraging; alcohol injection does not offer permanent resolution of symptoms for most patients, can be associated with considerable morbidity and that results are not comparable to surgery. Our investigation provides the only long term data for alcohol injection treatment of MN

Morton’s syndrome is an entrapment of a digital nerve between the metatarsal heads in the foot causing pain between the metatarsal heads. 41 subjects with signs and symptoms of Morton’s syndrome were prospectively examined with an ultrasound scan and the size of the bifurcation of the interdigital nerve was recorded if it was visible. Each subject completed a Visual Analogue Scale and short form McGill Pain Questionaire before an injection of local anaesthetic and corticosteroid was administered. The subjects were reviewed after 6 weeks and the pain scores repeated.

26 subjects had positive ultrasounds with a mean width of 5.1 mm, range 2.7–9.8 mm and 15 subjects had negative ultrasounds. Differences in mean ranks of VAS scores between the two groups were borderline statistically significant for scores before injection (p=0.064). Difference in mean rank of VAS score was significant after injection (p=0.013).

Differences in mean ranks of MPQ scores were borderline statistically significant for changes in scores (p=0.062). Difference in mean rank of MPQ score was significant after injection (p=0.007). None of the correlations between nerve width and any of VAS or MPQ outcome measures were statistically significant.

This study demonstrates that the larger the neuroma on the ultrasound, the more painful it is for the patient. This study suggests that patients who have a small or absent neuroma demonstrated on the ultrasound scan are more likely to have their pain reduced to an acceptable level with an injection of local anaesthetic and corticosteroid than those patients with a large neuroma. Ultrasound examination is a useful tool in the management of patients with Morton’s syndrome.

Objective of the Study: To assess the clinical effectiveness of ultrasound guided injection in the management of Morton’s Metatarsalgia. Patients and Methods: Patients, that were clinically diagnosed to with interdigital Morton’s neuroma were treated with ultrasound guided injection of local anaesthetic and steroid. Fifty three patients were available for follow-up, and all had detailed telephone questionnaires completed. These questionnaires included a pre and post injection symptom score, as well as a Johnson Satisfaction score. Results: 69% of patients had ultrasound diagnosis of Morton’s neuroma and 31% had an ultrasound diagnosis of intermetatarsal bursa. Mean follow up was11.4 months (Range: 3-23 months).67% of the patients were satisfied with the results of treatment. At follow up 63% of patients had no limitation in activity levels, and had no need to modify their shoe wear. Of all patients included in the study, only 3 patients have gone on to require surgery for ongoing symptoms. Conclusion: Some studies have suggested that neither injection nor imaging have a role in the treatment of Morton’s neuroma. This study, however, demonstrate that ultrasound guided placement of local anaesthetic and steroid in either an intermetatarsal bursa or Mor-ton’s neuroma gives a good short and medium term symptom relief and in the majority of cases avoids the need for surgery

Introduction. Up to 70% of patients with symptomatic Morton's neuroma proceed to surgery having failed non-operative management. The success of surgical excision is up to 85% but carries with it significant morbidity. Radiofrequency ablation (RFA) is a less invasive alternative. Methods. We studied a consecutive cohort of patients with Morton's neuroma that had failed non-operative treatment. Instead of undergoing surgical excision, these patients were referred for RFA. Under a local anaesthetic nerve block, RFA was performed under ultrasound-guidance, as an out-patient procedure, by a single radiologist. The procedure was repeated after 4 weeks if necessary. We followed patients for a minimum of 6 months to assess their change in visual analogue pain scores (VAS), overall symptom improvement, complications and progression to surgical excision. Results. 30 feet in 25 patients were studied. There were 4 males and 21 females with an average age of 55 years (range 33–73 y). All had tried previous methods of non-operative management. 40% presented with 2. nd. space neuromas and 60% with 3. rd. space. The average number of treatment sessions was 1.6 (range 1–3, mode 1). Prior to treatment, all patients had pain on activity (VAS average: 6.0, range 3–9). At 6 months post treatment, there was a statistically significant reduction in pain scores (post RFA VAS average: 1.7, range 0–8, p<0.001). The average overall symptom improvement was 76%. There was one minor complication of temporary nerve irritation. 3 neuromas (10%) have progressed to surgical excision. 1 patient has ongoing, unchanged pain with no obvious cause. At 6 months, 26 out of 30 feet had a satisfactory outcome. Conclusion. RFA has potentially reduced the need for surgical excision of Morton's neuromas by >85%
