Subdural Traction and Posttraumatic Headache

Arachnoid Rupture as Cause of the Postconcussion Syndrome

“…Probably subdural air could be observed more frequently if tilting of the head was a routine part of the pneumoencephalographic procedure, as indicated in the studies by uon Sforch & Buermann (1939) and Penfield & Norcross (1936). Air studies are rarely pxformed immediately after a n "uncomplicated" cerebral concussion and arachnoid tears may have healed before the examination is done.…”

The Post-Traumatic Convulsive and Allied States.

“…Large amounts of air may escape into the subdural space. This is commonly seen following head injuries, even in late cases (Penfield and Norcross, 1936), and bespeaks a lepto-meningeal abnormality. Another type of lesion, which may or may not be combined with the former, results in a dilatation of the lateral and perhaps the third ventricles.…”

Chronic Posttraumatic Headache

“…Penfield and Norcross, 9 believed that these adhesions caused traction and pressure on sensory nerves of the dural vessels. Penfield and Norcross, 9 believed that these adhesions caused traction and pressure on sensory nerves of the dural vessels.…”

“…Even in minor head injures, adhesions may form between the arachnoid and dura mater due to small subdural hemorrhages. Penfield and Norcross, 9 believed that these adhesions caused traction and pressure on sensory nerves of the dural vessels. They sought to relieve the headaches by breaking up these adhesions by air insufflation.…”
