Management of interhemispheric pathologies requires surgical intervention through a restricted anatomical corridor ensconced within critical cerebral structures. The use of retractors to facilitate operative access may cause damage to cerebral tissue. The development of an innovative retraction technique designed to alleviate cerebral damage in such cases is imperative. In this study, we present a novel and gentle retraction method to facilitate the interhemisferic approach. ⋯ The ideal retraction technique during the interhemispheric approach is still a challenge. Our novel retraction technique may help minimize brain parenchymal damage during surgical resection of interhemispheric lesions.

Little research has been done to evaluate the prognostic value of short-term postoperative patient-reported outcomes (PROs) on long-term PROs following lumbar decompression (LD). We evaluated the prognostic value of short-term PROs on long-term PROs through 2 years after LD. ⋯ The 6-week postoperative PROs are predictive of the same outcomes at 6 months, the PROMIS-PF is predictive through 1 year, and the PHQ-9 is predictive through 2 years. Determining the predictive value of early postoperative PROs can be helpful in understanding the likely postoperative trajectory following LD and informing patient expectations.

Mucopolysaccharidosis type IVA is a lysosomal storage disorder caused by a deficiency of the enzyme N-acetyl-galactosamine-6-sulphate sulphatase. Mucopolysaccharidosis type IVA is multisystemic disease with significant spinal involvement and atlantoaxial instability leading to neural compression and significant morbidity. Dens hypoplasia is a common feature of this condition. In this study we demonstrate that after spinal fixation, there is new growth of dens in significant proportion of patients, suggesting atlantoaxial instability as one of the major driving forces of lack of development of dens in this condition.
