title: Percutaneous lumbar nuclectomy according to the Onik method: indications, technique, first results.
abstract: The authors report their first experience with 20 cases of lumbar herniated disc treated by percutaneous nuclectomy according to the Onik method. The methods used for a precise preliminary assessment of the prolapse in order to establish correct indications are discussed. The technique of the operation is then described. The simplicity and relative absence of trauma in this type of surgery, associated with the patient's rapid recovery, drastically reduces hospitalization time, with consequent social and economic advantages. The clinical results at follow-up are sufficiently rewarding to suggest a wider use of this method, but it is essential to restrict it to the indications laid down, which are fully illustrated. The method is applicable only to contained hernias and is contra-indicated in extruded hernias.
