A rare case of bilateral occipital condyle fractures associated with inferior clivus separation fracture resulting in craniocervical dislocation: a case report and modification of the Anderson and Montesano classification is proposed.

The authors report a very rare case of bilateral occipital condyle fractures (OCF) that was associated with complete separation fracture of the inferior clivus resulting in craniocervical dislocation alongside dissociation of C1-C2 joint complex. Also, a new type of the Anderson and Montesano classification system is presented with two subtypes of injuries. Type IVA occurs when the OCF is associated a clivus avulsion fracture, while Type IVB occurs when the OCF is associated with complete "en piece" separation fracture of the inferior clivus.

Cross-cultural adaptation and validity of an adapted Brazilian Portuguese version of Scoliosis Research Society-30 questionnaire.

Study Design: Prospective clinical study developed at a tertiary teaching facility to test an adapted Brazilian Portuguese version of the Scoliosis Research Society-30 (SRS-30) questionnaire.

Objective: To perform cross-cultural adaptation and evaluate the validity of the adapted Brazilian Portuguese version of SRS-30 questionnaire.

Summary Of Background Data: Quality-of-life measurement is a common practice to assess spine diseases.
