This is an observational, single-center and single-operator study. Between July and December 2019, forty patients who underwent first ray surgery (hallux valgus or rigidus) and eligible for outpatient treatment were included. The surgical technique of the hallux valgus treatment consisted of open surgery via double metatarsal and phalangeal osteotomy. The hallux rigidus surgery consisted of arthrodesis using an open dorsal plate. Home monitoring was carried out by a healthcare provider (e-HORUS). The protocol provided for pain management by means of a diffuser of Nefopam IV for a maximum of 5 days, combined with alleviating oral analgesics 1 and 2 and NSAIDs. The pain was evaluated on D0, D1, D3, D5, D8 and D15, using a numerical scale (NS) from 0 to 10. The degree of patient satisfaction was recorded at 1 month.
35 patients were followed. 5 patients were excluded due to incomplete data. The series included 26 women and 9 men, with an average age of 59.9 years. There were 30 hallux valgus and 5 hallux rigidus. The pain analyzed by the NS was 5.37 on D0, 3.34 on D1, 1.83 on D3, 1.43 on D5, 1.06 on D8 and 2.2 on D15. The average duration of Nefopam infusions was 3.89 days, and the average duration of oral analgesics was 17.7 days. The tolerance of the treatment was satisfactory in 79% of the cases. 69% of patients were very satisfied with the management of their pain. There were no scar complications or infections. No re-hospitalization was necessary. 3 algoneurodystrophies were identified. The existence of fibromyalgia or Parkinsonian syndrome was correlated with higher pain.
Pain management after outpatient first ray surgery using the injectable Nefopam protocol was satisfactory in the majority of cases, with a high degree of patient satisfaction. This protocol is routinely offered to our patients who must undergo first ray surgery.
