Evidence for Juvenile Disc Herniation in a Homo Erectus Boy Skeleton

  title={Evidence for Juvenile Disc Herniation in a Homo Erectus Boy Skeleton},
  author={Martin Haeusler and Regula Schiess and Thomas Boeni},
Study Design. An analysis and differential diagnosis of bony alterations in the lower lumbar vertebrae of a Homo erectus boy skeleton. Objective. To analyze low back problems during early human evolution. Summary of Background Data. Back problems in modern humans are often attributed to our upright, bipedal locomotion that is thought to place huge mechanical stresses on the vertebral column. However, little is known of this situation during the course of human evolution. Methods. We analyzed… 
Revisiting scoliosis in the KNM-WT 15000 Homo erectus skeleton.
No skeletal dysplasia in the Nariokotome boy KNM-WT 15000 (Homo erectus)--a reassessment of congenital pathologies of the vertebral column.
The Nariokotome boy fossil seems to belong to a normal Homo erectus youth without pathologies of the axial skeleton, and the absence of platyspondyly refutes axial dysplasia and disproportionate dwarfism.
Spinal Pathologies in Fossil Hominins
An overview of the known spinal pathologies in the hominin fossil record is presented, including spondylolisthesis in the Pelvis 1 individual from Sima de los Huesos, traumatic juvenile disc herniation in KNM-WT 15000 (Homo erectus) and Scheuermann’s disease in A. afarensis.
How Did the Pelvis and Vertebral Column Become a Functional Unit during the Transition from Occasional to Permanent Bipedalism?
It is shown that pelvic incidence increases and lumbar lordosis develops when the infant learns to walk, leading to a correlation between these parameters, and a chain of correlations between the six angular parameters are observed.
Percutaneous endoscopic interlaminar discectomy for pediatric lumbar disc herniation
PEID shows a satisfying outcome with a minimal rate of complications and has the advantages of minimal traumatization and scar formation and is a safe and effective treatment for PLDH.
Percutaneous Endoscopic Interlaminar Discectomy for L5-S1 Adolescent Lumbar Disc Herniation.
Considering specific anatomical peculiarities and expectation for rapid recovery, PEID is a safe and effective minimally invasive technique for ALDH at the L5-S1 level.
Spinal cord evolution in early Homo.
Whole Spine Disc Degeneration Survey according to the Ages and Sex Using Pfirrmann Disc Degeneration Grades
Disc degeneration is natural course after one’s 2nd decades, and its incidence and grade were increased with age, and more affected by sexual difference after 6th decades.
Morphology, pathology, and the vertebral posture of the La Chapelle-aux-Saints Neandertal
The spinal posture of La Chapelle-aux-Saints 1 is reassessed using a new pelvic reconstruction to infer lumbar lordosis, interarticulation of lower lumbAR (L4-S1) and cervical (C4-T2) vertebrae, and consideration of his widespread age-related osteoarthritis.
An evolutionary hypothesis to explain the role of deconditioning in low back pain prevalence in humans
An evolutionary hypothesis relating to the role of deconditioning in the prevalence of low back pain (LBP) in humans is presented and the hypothesis that an evolutionarily determined factor might predispose LBP across a wide range of Homo sapiens populations seems plausible to examine.


Facet Joint Asymmetry as a Radiologic Feature of Lumbar Intervertebral Disc Herniation in Children and Adolescents
Facet joint asymmetry is a radiologic feature of lumbar intervertebral disc herniation in children and adolescents, and the frequency in the juvenile group was five times higher than that in the adult group.
Adolescent lumbar disc disease: findings and outcome
Operative intervention in the form of simple discectomy offers good result in 92% of lumbar disc herniation cases irrespective of approach and method.
Middle Pleistocene lower back and pelvis from an aged human individual from the Sima de los Huesos site, Spain
A revised reconstruction of Pelvis 1, together with the current fossil evidence, confirms the previous hypothesis that the morphology of this pelvis represents the primitive pattern within the genus Homo, and argues that this primitive pattern is also characterized by sexual dimorphism in the pelvic canal shape, implying complicated deliveries.
Lumbar disc herniation in patients up to 25 years of age.
The condition of the bony structures seems to be more important than the condition ofThe disc tissue in the occurrence of herniated lumbar discs in young patients.
Age-related disk degeneration: preliminary report of a naturally occurring baboon model.
Anteroposterior and lateral radiographs of 126 adult baboons were reviewed. The mean age was 15.7 years (range 6-30 years). Evidence of disk degeneration, to include disk-space narrowing, osteophyte
Vertebral pathology in the afar australopithecines.
The presence of Scheuermann disease in the AL-288 column suggests that lifting, climbing, or acrobatic activities may have been important in early hominids.
Vertebrae numbers of the early hominid lumbar spine.
Doubts are raised about previous conclusions for the presence of six lumbar vertebrae in early hominids and the most parsimonious explanation is that they did not differ from modern humans in the segmentation of the vertebral column.
A review of current treatment for lumbar disc herniation in children and adolescents
It was found that pediatric patients responded less favorably to conservative treatment as compared with adults, and the outcome of surgery remained to be satisfactory for at least 10 years after the initial operation, even though it appeared to deteriorate slightly.
Spondylosis in sand rats: A model of intervertebral disc degeneration and hyperostosis
This study defines gross, histopathologic, and radiologic changes associated with intervertebral disc degeneration in a spontaneously occurring form of the disease in aging sand rats (Psammomys
