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

Regional anaesthetic for foot surgery has been discussed as a method of post operative analgesia. Ankle block as the sole anaesthetic for foot surgery has not been extensively reviewed in the literature. Aim. To describe our experience of forefoot surgery under ankle block. Methods. 71 consecutive forefoot procedures (65 patients) were carried out under ankle block. A mixture of 10ml 2% Lidocaine with 10ml 0.5 % Bupivacine was administered to the superficial peroneal, deep peroneal, sural and saphenous nerves. Ankle tourniquet was employed in all procedures. Patients were contacted post operatively and completed a standardised questionnaire including an incremented pain assessment ranging from 0-10 (0 no pain, 10 severe pain). Results. 61 female and 4 male patients were contacted (age range 33-67y). Procedures included 48 first metatarsal osteotomies, 15 cheilectomies, 2 first MTP joint replacements, and 6 fusions. 17 patients (26 %) reported some discomfort during the block procedure (average pain score 1.2). No patients reported any pain during their operation(s). 14 patients (22%) required supplementation of the block. Average pain score at 6, 12, 24 and 48 hours following surgery were 0.66, 2.9, 2.4 and 1.3 respectively. All patients were discharged home and walking on the same day. None complained of nausea or required parentral analgesia. There were no readmissions. Each patient confirmed they would have surgery under regional block rather than general anaesthesia and would recommend this technique to family and friends. Discussion. There are many advantages in being able to perform these small procedures under regional anaesthesia. Our initial observational study suggests forefoot surgery under ankle block alone may be safe and effective. Anaesthesia obtained permits the majority of forefoot procedures and provides lasting post-operative analgesia. Combined with intra-operative sedation, use of ankle tourniquet and same day discharge it has very high patient acceptance and satisfaction
