The Compass Elbow Hinge: indications and initial results.

The Compass Elbow Hinge uses Illizarov's methods of fixation to externally hold the elbow reduced and allow both passive and active motion. Eleven patients with degenerative disease, contracture or instability were treated with the Compass Elbow Hinge and were retrospectively evaluated at an average follow-up of 29 months (range: 18-62 months). One was lost to follow-up. Patients with degenerative changes underwent fascia lata interposition while those treated for contractures underwent anterior and posterior capsular release with or without fascia lata interposition. Those with elbow instability underwent ligament reconstruction. The device was removed after 6 weeks and seven of the 11 patients were satisfied with the outcome of the operation. Stability could not be achieved in two patients with coronoid fractures that were not reconstructed. One patient did not tolerate the device and requested its removal with subsequent subluxation. We conclude that patient selection and compliance are key elements in achieving a satisfactory outcome with the device.

Two-stage extensor tendon reconstruction after composite tissue loss from the dorsum of the hand.

Restoration of digital extension after chronic extensor loss has not been detailed extensively in the literature. The present report details an unusual case of composite tissue loss from the dorsum of the hand after a chronic burn wound. After debridement for chronic carpal osteomyelitis and free-tissue transfer were performed, staged wrist fusion and two-stage extensor tendon reconstruction resulted in a stable, pain-free wrist and functional digital extension. The present case illustrates that two-stage extensor tendon reconstruction, when necessary, is indeed feasible.

Posterior interosseous nerve palsy following placement of the compass elbow hinge for acute instability: a case report.

We describe a case of posterior interosseous nerve palsy that developed after application of a hinged elbow external fixation device. Our hypothesis that forearm pronation during ulnar half pin insertion may have been causative is supported by anatomic findings noted during subsequent cadaveric dissection. Based on our observations we recommend that the ulnar half pins required with this device be inserted with the forearm in supination.

Identification of an arteriovenous fistula during free tissue transfer despite negative preoperative angiography: a potentially correctable cause of venous thrombosis.

Although refinements in microvascular technique have resulted in great success with free tissue transfer, long-term anastomotic patency, particularly venous, is less predictable in patients with a history of intravenous drug abuse or other causes of intimal damage and/or venous hypertension. We report an unusual case in which an arteriovenous fistula was identified intraoperatively as the cause of pulsatile venous backflow despite a normal preoperative angiogram. A flow disturbance at the site of venous anastomosis and subsequent development of a venous thrombosis prompted more proximal venous exposure and the identification of an arteriovenous fistula. Once ligated, pulsatile venous backflow resolved and successful revision of the venous anastomosis was performed. This case illustrates that an anomalous arteriovenous communication must be considered when high-pressure venous backflow is observed intraoperatively, despite no evidence of an arteriovenous fistula on preoperative angiography, because, if identified and ligated, an arteriovenous fistula may represent a treatable cause of venous thrombosis.

Technique for ensuring ulnohumeral reduction during application of the Richards compass elbow hinge.

The compass elbow hinge is an externally applied device that allows both active and passive range of motion after placement. It is effective for treatment of posttraumatic elbow contractures and of the arthritic elbow with posttraumatic arthritis and also in cases of acute instability despite radial head replacement or fracture fixation and ligamentous repair. The device is technically challenging to apply and requires that the assistant maintain ulnohumeral reduction during application, particularly of the ulnar pins. We describe a simple technique that ensures reduction and shortens surgical time tremendously.
