Minimally invasive surgery (MIS) has gained popularity for hallux valgus, compared to the traditional scarf osteotomy (OS). Though evidence suggests similar clinical outcomes, there is paucity of randomised controlled studies. This study aimed to assess the feasibility of conducting a randomised controlled trial comparing the patient recorded and clinical outcomes for the surgical management of Hallux Valgus between OS and MIS Chevron Akin (MICA).

The aim of this retrospective study is to compare the different anaesthetic techniques in children undergoing circular frame application for lengthening and deformity correction. Data was collected from 68 cases on severe pain episodes, postoperative duration of analgesia, requirement for top-up analgesia, complications and side-effects and number of osteotomies. The three analgesic methods used were morphine infusion (M), epidural analgesia (E) and continuous peripheral nerve blocks (CPNB). There was a significant difference between the number of episodes of severe pain experienced by the patients receiving a morphine infusion when compared to the epidural and CPNB groups (M vs. E p<0.0001, M vs. CPNB p=0.018). CPNB were associated with the lowest incidence of severe pain episodes and top-up analgesia requirements. The difference in the incidence of nausea and vomiting between the methods was approaching significance (p=0.06). A significant difference was found when comparing epidural and morphine infusions (p=0.05). Epidural analgesia was associated with significantly more nausea and vomiting (p=0.023), and motor blockade (p<0.01) than CPNB. The results show the most effective method of post-operative analgesia for our paediatric patients, in light of pain episodes and associated side-effects, is sciatic nerve catheterisation with continuous infusion.
