Dysbaric bone necrosis demonstrated in ichthyosaurs may be the result of prolonged deep diving rather than rapid ascent to escape predators. The bone lesions show structural and anatomical similarity to those that may occur in human divers and in the deep diving sperm whale, Physeter macrocephalus. 

The Permian and Triassic in the Albanian Alps

The sedimentary succession of the Permian to Middle Triassic of the Albanian Alps is described, as part of the eastern Adria passive margin towards the Tethys. A carbonate ramp deepening towards NE

Perspectives on decompression syndrome and the methodology of science

TLDR
While pulmonary parenchymal disruption certainly can be considered a complication of decompression associated with rapid ascent, Hayman's reference to it as decompression illness may cause semantic confusion to those interested in natural diving physiology.

Adaptations for marine habitat and the effect of Triassic and Jurassic predator pressure on development of decompression syndrome in ichthyosaurs

TLDR
Examination of a large Triassic sample of ichthyosaurs finds that diving in the Triassic appears to have been a “leisurely” behavior until the evolution of large predators in the Late Jurassic that forced sudden depth alterations contributed to a higher occurrence of bends.

Radiology of Dysbaric osteonecrosis.

TLDR
Dysbaric osteonecrosis is a major hazard to compressed air workers and an increasing danger to divers especially with longer exposure times at greater depths and all other causes of aseptic necrosis of bone must be kept in mind.

Dysbaric osteonecrosis: a reassessment and hypothesis.

TLDR
Despite detailed examination of this problem by many authorities, dysbaric osteonecrosis still remains a significant occupational hazard with serious medico-legal consequences, and preventative measures are being based upon an incomplete understanding of the pathophysiology of the disease, and that other etiological factors are perhaps being overlooked.

Nontraumatic osteonecrosis of the humeral head.

TLDR
Surgical treatment includes arthroscopic debridement and core decompression for early osteonecrosis and hemiarthroplasty or total shoulder arthroplasty for more advanced disease.
