First metatarsophalangeal joint (MTPJ) arthrodesis plays a significant role in the management of symptomatic hallux rigidus. Several open and very few percutaneous techniques have been described in the literature. The authors present a new minimally invasive technique along with patient reported outcome, radiological parameters and a discussion on this novel technique. A total of fifteen cases of first MPTJ arthrodesis were included in this prospective continuous series from September 2011 to June 2012. Mean age was 56 years and the indication for surgery was hallux rigidus in 13 of 15 cases. All patients underwent the same minimally invasive procedure by the same primary surgeon (AHS), 13 of 15 as day cases. Clinical outcome and patient satisfaction were assessed by the Manchester-Oxford Foot Questionnaire (MOXFQ) preoperatively and at most recent follow up. Radiographic and clinical evaluation of fusion was also assessed. No patients were lost to follow up and all scores were collected by an independent surgical practitioner to avoid bias. Mean follow up was six months (range 1 to 9 months). The MOXFQ score for cases where fusion was achieved (n=14) improved from a mean 40/64 preoperatively to a mean 15/64 at last follow up ( This minimally invasive technique for first MTPJ arthrodesis is simple and can achieve results similar or better than open techniques in experienced hands. Further cases are needed to expand this series and evaluate for further complications.
Forefoot surgery causes postoperative pain which requires strong painkillers. Regional blocks are now increasingly used in order to control postoperative pain especially in the first twenty four hours when the pain is at its worst. We conducted a study to see whether timing of ankle block i.e. before or after application of tourniquet shows any difference in efficacy in postoperative analgesia in first twenty four hours. A prospective study was conducted between September and March 2011 involving 50 patients. Group A had ankle block after and Group B had block before application of tourniquet. Both group had twenty five patients each. Patients were given assessment forms to chart their pain on Visual Analogue Scale (VAS) at 4hrs and twenty four hours after surgery. Both groups demonstrated good postoperative pain control. Average pain score at four and twenty fours after surgery was 2.5 and 5 in Group A and 3.5 and 6.1 in Group B respectively. Pain control, both at four and twenty four hours surgery was better in Group A but this was not statistically significant. Ankle block should be routinely used in forefoot surgery to control postoperative pain. Ankle block before or after the application of tourniquet had comparable pain relief with no statistical difference.
