Between 1993 and 2000, 61 patients with instability-related coccygodynia were operated on by a single surgeon using the same technique. There were 49 women and 12 men, mean age 45.3 (18–72) years. Twenty-seven patients had hypermobility of the coccyx and 33 subluxation. In all cases, the unstable portion was removed through a limited incision directly over the coccyx. The outcome was assessed using a detailed questionnaire. Follow-up was between 12 months and more than 30 months. The outcome was rated excellent or good in 53 patients, fair in one, and poor in seven. There were nine patients with infection requiring reoperation.

Il y avait 49 femmes et 12 hommes, d’âge moyen âge 45.3 ans (18–72). Vingt-sept malades avaient une hypermobilité du coccyx et 33 une subluxation. Dans tous les cas, la portion instable a été enlevée par une incision limitée, directement sur le coccyx. Le résultat a été apprécié en utilisant un questionnaire détaillé. Le suivi était entre 12 mois et plus de 30 mois. Le résultat a été estimé excellent ou bon pour 53 malades, moyen pour un, et mauvais pour sept. Il y avait neuf malades avec une infection qui a nécessité une réintervention.
