The use of the Vidal-Adrey external fixation system. Part 1: The treatment of open fractures.
The average time for healing of open fractures treated by the Vidal-Adrey external fixation method was 9 1/2 months for the lower extremity and 4 months for the upper extremity injuries. In a series of 33 cases, the results were excellent or good in 21.
The use of the Vidal-Adrey external fixation system. Part 2: The treatment of infected and previously infected pseudarthrosis.
A total of 23 infected or previously infected non-unions were treated by the Vidal-Adrey modification of the Hoffmann apparatus. The external fixators were applied after decortication and bone grafting either immediately in cases with no evidence of infection or later in cases of draining, infected wounds. The average healing time for these non-unions, that is time when no external support was required, was 12 months after the initial application of the Vidal-Adrey external fixators. The results were considered good or acceptable in 21 of 23 cases. Union occurred in 21, although union did not necessarily mean a good result overall when all other factors (shortening, etc.) were considered. This fixation device, when correctly applied and in conjuction with adequate debridement and bone grafting is an excellent method for the treatment of severe non-unions where infection is or was a problem.
The use of a peritoneal catheter for the irrigating system in arthroscopy: a better system for accurate diagnosis.
The use of a peritoneal catheter enhances diagnosis using arthroscopy by affording a clear visibility of the knee joint. The accuracy in diagnosis is significantly enhanced using this method of irrigation. No better method of irrigation is available for cases of acute knee joint injuries.

An analysis of differential epidural spinal anesthesia and pentothal pain study in the differential diagnosis of back pain. Aids in avoiding unnecessary back surgery.
The selection of the proper patient for back surgery is of prime importance and is the topic of this report. An analysis of patients evaluated with differential epidural spinal anesthesia and the Pentothal pain study show these tests to be helpful in separating those patients with primarily organic pain who could benefit from surgery from those patients with primarily functional pain who should not be operated upon. These tests will help one determine whether a disability is related to the severity of pain, to the patient's emotional response to pain, or to a somatic manifestation of a gross emotional breakdown.

The use of the Varney brace for subluxating shoulders in stroke and upper motor neuron injuries.
Applying the Varney shoulder brace for painful subluxating shoulders in stroke and head injury patients with or without spasticity has proved to be an extremely effective means of reducing the subluxed shoulder. Other causes for painful shoulders in these patients must be ruled out. Not every shoulder which subluxes with or without spasticity is painful. Correct diagnosis of the etiology of the pain is essential to help the patient. Rotator cuff tendinitis, reflex sympathetic dystrophy, glenohumeral arthritis, shoulder contracture, pain due to central nervous system origin (thalmic pain) and other intrinsic causes of referred pain must be ruled out. Once the subluxed shoulder is proven to be the cause of pain, the Varney brace is an excellent orthosis for the reduction and maintenance of position. Pain usually subsides completely within 5 to 7 days.
