Objectives

“Virtual fracture clinics” have been reported as a safe and effective alternative to the traditional fracture clinic. Robust protocols are used to identify cases that do not require further review, with the remainder triaged to the most appropriate subspecialist at the optimum time for review. The objective of this study was to perform a “top-down” analysis of the cost effectiveness of this virtual fracture clinic pathway.

The use of passive stretching of the elbow after arthrolysis is controversial. We report the results of open arthrolysis in 81 patients. Prospectively collected outcome data with a minimum follow-up of one year were analysed. All patients had sustained an intra-articular fracture initially and all procedures were performed by the same surgeon under continuous brachial plexus block anaesthesia and with continuous passive movement (CPM) used post-operatively for two to three days. CPM was used to maintain the movement achieved during surgery and passive stretching was not used at any time. A senior physiotherapist assessed all the patients at regular intervals. The mean range of movement (ROM) improved from 69° to 109° and the function and pain of the upper limb improved from 32 to 16 and from 20 to 10, as assessed by the Disabilities of the Arm Shoulder and Hand score and a visual analogue scale, respectively. The greatest improvement was obtained in the stiffest elbows: nine patients with a pre-operative ROM < 30° achieved a mean post-operative ROM of 92° (55° to 125°). This study demonstrates that in patients with a stiff elbow after injury, good results may be obtained after open elbow arthrolysis without using passive stretching during rehabilitation.

We present a retrospective study of 25 patients treated by open arthrolysis of the elbow for post-traumatic stiffness. The mean follow-up was for 7.8 years (5 to 10.8). The range of movement of the elbow, pain scores and functional outcomes were recorded pre- and postoperatively. An improvement in the mean range of movement from 55° (0° to 95°) to 105° (55° to 135°) was obtained in our patients at one year. This improvement was maintained over the mean follow-up period of 7.8 years (5 to 10.8). Improvement in pain, function and patient satisfaction was recorded in 23 of the 25 patients at final follow-up.

On the basis of this study, we believe that the results of open arthrolysis for post-traumatic stiffness of the elbow are durable over the medium term.

40 linked total elbow replacements were inserted into 35 patients over a 12-year period. The mean age was 67. 3 years, (range 48 to 87 years) and the mean follow up 50 months (range 8 to 134 months). Each patient had undergone at least 1 operation prior to the index arthroplasty (range 1 to 10). 27 elbows were flail and 13 unstable due to previous failed total elbow replacements in 23, gross bony erosion due to rheumatoid arthritis in 9, distal humeral non-union in 6 and Charcot joints due to syringomyelia in 2.

A Coonrad Morrey sloppy hinge prosthesis was implanted in 25 elbows and a snap-fit Souter Strath-clyde prosthesis in 15. The technique included preservation of the triceps mechanism and early mobilisation in most cases. At review 38 elbows had no or mild pain, 2 moderate, and no patient had severe pain. All patients achieved a functional range of movement. There was no linkage failure of any implant.

Complications included revision for aseptic loosening of one humeral and one ulnar component, debridement for infection in one and curettage and bone grafting of a cement granuloma in one. One patient with a Charcot joint developed a non-union after failure of plating and grafting of a periprosthetic fracture at the tip of the humeral component. In addition six had delayed wound healing, two ulnar nerve symptoms and two triceps weakness.

In conclusion, a linked elbow replacement can reliably provide stability, mobility and pain relief in a flail or unstable joint allowing the hand to be positioned in space and therefore the function of the limb is dramatically improved. This method is especially appropriate in elderly frail patients.
