The calcaneus of Australopithecus afarensis and its implications for the evolution of bipedality.

Calcanei from African apes, modern humans, and Australopithecus afarensis are compared to investigate the anatomical and mechanical changes that occurred in this bone as a result of the transition to terrestrial bipedality. Features analyzed include the cross-sectional area and volume of the calcaneal tuber, the geometry and orientation of the articular surfaces, and the surface topography of the calcaneal corpus. Calcaneal morphology is unequivocal in its partitioning of quadrupedal pongids and bipedal hominids.

Vertebral body and posterior element morphology: the normal spine in middle life.

Multiple morphologic parameters were studied in 50 normal adult vertebral columns ranging in age from 20 to 40 years at the time of death. Posterior element morphology is highly variable and largely unpredictable. Minimum pedicle diameters ranged from 1.8 mm at T6 to 6.4 mm at L5, and did not correlate with any more readily measured vertebral dimensions. Penetration of 5 mm screw threads through pedicle cortex can be expected to occur routinely in the lower thoracic spine, and in a lesser but significant number of lumbar vertebrae.

Talocrural joint in African hominoids: implications for Australopithecus afarensis.

Talocrural joints of the African apes, modern humans, and A.L.288-1 are compared in order to investigate ankle function in the Hadar hominids. Comparisons between the hominids and African pongids clearly illustrate the anatomical and mechanical changes that occurred in this joint as a consequence of the evolutionary transition to habitual bipedality. Features which are considered include the obliquity of the distal tibial articular surface, the shape of the talar trochlea, and the location and functional implications of the talocrural axis. In every functionally significant feature examined the A.L.288-1 talocrural joint is fully bipedal. Moreover, the Hadar ankle complex also shows the functional constraints which are necessarily imposed by the adaptation to habitual bipedalism.

Home visits after hospitalization: enhancing baccalaureate nursing students' gerontologic clinical experience.

This article describes posthospitalization visits by 83 nursing students to 57 older patients and their caregivers discharged from two large academic medical centers and one community hospital. Patient and caregiver interviews in the home focused on the areas of geriatric assessments of cognitive and functional status, patient and caregiver satisfaction with recent hospitalization, ongoing health management, patient teaching, and discharge planning.
