“…0 único processo que poderia evitar o deslocamento do áxis e bás-cula, no sentido dorsal, da apófise odontóide, seria uma sólida imobilização do atlas e epistrófeo. List 10 propôs que se fixasse a apófise espinhosa do áxis ou da terceira vertebra cervical, por meio de um enxerto sólido; assim, no caso 1 deste autor foi praticado um enxerto ósseo autógeno, paramediano, desde o ocipital à quinta vertebra cervical. Este processo também é recomendado por Hadley 8 M. V. M., 27 anos de idade, branco, mecânico, reg.…”

“…Deformative stress due to chronic flexion extension injuries were noted in patients with angulation of the brainstem [76,78,79,84] and attributed to the fulcrum effect of the medullo-spinal junction draped over the odontoid [17]. Deformative stress is evident in achondroplasia [85][86][87][88][89], platybasia [84,90,91], acquired bonesoftening conditions such as rickets, hyperparathyroidism, spondyloepiphyseal dysplasia, acroosteolysis, Hurler's Syndrome, osteomalacia, achondromalacia, renal osteodystrophy, Paget's disease, and degenerative conditions such as rheumatoid arthritis [35,51,72,[92][93][94][95][96][97][98][99] and osteogenesis imperfecta [100,101].…”

“…The deformative stress imposed upon the neuraxis by flexion of the neck and craniocervical junction, such as occurs in whiplash injury, is manifest radiologically by the measurement of increased length of the medulla and spinal cord [5,12,14,17,18,22,46,49,51,52,61,64,68,[70][71][72][73][74][75][76][77][78][79] (Figs. 4A-C).…”

Study Design:A prospective 1-year follow-up study of whiplash patients presenting with neurological signs/or symptoms (WADIII), and whiplash patients with neck pain but no neurologic findings (WADI/II). Objective:We hypothesize that WADI/II and WADIII are distinct entities, with regards to clinical presentation, pathoanatomy, and prognosis.Summary of Background Data: symptoms associated with whiplash injury range from mild neck pain (WADI/II), to injuries associated with neurologic sequellae (WADIII). To date, literature considers whiplash associated disorders (WAD) a single clinical and pathologic entity, with different grades of severity (WADI-IV).Methods: Thirty one subjects were divided into a WADIII study group and a WADI/II comparison group. All subjects underwent H&P, radiographic evaluations, and clinical outcome measures (collected at 3, 6, and 12 months). Statistical analysis was performed (Student T-test, Wilcoxon Signed-Rank test) with significance set at p=0.05. A finite element analysis (FEA) technology (SCOSIA©) was used to predict stresses within the neuraxis.Results: At day 0: Better neurologic assessments, functional performances, and higher quality-of-life measurements were noted in WADI/II compared to WADIII. VAS scores were comparable.At 12 months: Both groups reported improvements in neurologic status and disability symptoms. However functional recovery and quality-of-life measures significantly improved in WADIII, and conversely deteriorated in WADI/II along with notable worsening of pain symptoms. Litigation claims were comparable. FEA predicted higher stress within the neuraxis of WADIII, notably in subjects with preexisting stenosis and odontoid retroflexion. Conclusion:WADI/II and WADIII are distinct entities. Musculoskeletal injury precipitates WADI/II pain symptoms while neuronal stretching leads to WADIII neurologic injuries, which are mostly recoverable.

“…In their series, some patients had improvement of preoperative symptoms. The publication of Garner and Goodall appears to have resulted in the widespread adoption of posterior fossa decompression for hindbrain herniation with larger reports following over the next few decades [1,5,7,9,10,13].…”

Over the past several decades, our understanding of the pathophysiology of hindbrain hernias has markedly increased. Additionally, with the advent of MRI, diagnosis of these entities is common. Although the history of the discovery of what are now known as the Chiari malformations is well known, publications regarding the historical surgical treatment of these is, to our knowledge, not extant. Many have attributed the first successful patient series to Gardner in the 1950s. However, and unknown to many, the first description of a hindbrain decompression was in 1930 by the Dutchman Cornelis Joachimus van Houweninge Graftdijk. This neurosurgeon also added to our understanding the pathophysiology of hindbrain herniation and its relationship to raised intracranial pressure. The present paper reviews the contributions of this early pioneer of neurosurgery.
