The use of patient reported outcome measures (PROMs) of function is increasing in popularity. Self reported outcome instruments are used to measure change in health status over time allowing for the collection of accurate and relevant data on the quality of healthcare services. With recent changes outlined by the government, it will become increasingly important for surgeons to be able to demonstrate, with quantitative data, positive benefit of the surgery they perform. This study demonstrates the effectiveness of, and issues involved with setting up a PROMs database in a busy orthopaedic unit.

We have previously shown that a high proportion of our orthopaedic patients have access to the Internet. Suitable patients were identified at foot and ankle clinics or from surgical lists, and the well validated Foot and Ankle Ability Measure (FAAM) regional scoring system was used. The FAAM is a self-reported, region specific, instrument consisting of 21-item activities of daily living (ADL) subscale and an eight-item sports subscale. This was completed pre-operatively and also online at six-months post operatively, using limesurvey, a free online survey with internet/email based responses.

The software was simple to use and took about 4 hours to develop. 77% of the patient cohort for the period of study had email access and the majority of patients without email were happy to have the questionnaire completed over the phone. This took approximately ten minutes per survey. Patients who did not conduct the study prior to their admission were able to fill it in on the ward using a laptop.

This project has demonstrated that the initiation and continuation of a PROMs data collection system is feasible in a busy orthopaedic unit, producing reliable data which will enable us to monitor and improve standards of clinical practice. We discuss the issues involved with its introduction and usage.

Simultaneous arthrodesis of the ankle and subtalar joints is an established treatment option for combined ankle and subtalar arthritis or complex hindfoot deformities. The use of a curved intra medullary nail has potential advantages in terms of stability, hindfoot alignment and avoidance of the lateral neurovascular bundle.

We devised a comparative description of the results of hindfoot fusion using a curved locking nail before and after the introduction of anatomically specific modifications to the device through a retrospective review of notes and radiographs of patients undergoing simultaneous ankle and subtalar fusion by retrograde intramedullary nailing using an ACE¯ (Humeral Nail. Patients undergoing the same procedure using the Tibiotalocalcaneal [TTC] Nail System [DePuy] were recruited and studied prospectively. The outcome was assessed by a combination of notes review, clinical examination and telephone questionnaire.

Between 1996 and 2004, 71 arthrodeses in 67 patients have been performed. The average follow up is 27 months [3-73] and mean age 58 years. Fifty-two arthrodeses utilised the ACE humeral nail and nineteen used the newer TTC nail. Both nailing systems are locked proximally and distally and provide a short radius laterally directed distal curve. Mean time to union is 4.3 months [3-10]. Average AOFAS hindfoot score post-operatively is 65, with a mean improvement of 40 points from the pre-operative score in the TTC nail group. Post-operative complications included deep infection, amputation and a non-union rate of 10% overall. In the humeral nail group, four symptomatic stress reactions [8%] and three fractures of the tibia [6%] occurred at the tip of the nail. No stress-riser effect has to date been seen in the TTC nail group. Prominent metalwork removal has also been significantly reduced in the TTC nail group.

Our results show hindfoot fusion using a curved intramedullary nail to be an effective technique in complex cases of hindfoot arthritis and deformity. Anatomically specific alterations to the nail have resulted in a significant reduction in certain complications. Alternate proximal locking options in the TTC nail have reduced prominent metalwork and, more significantly, the incidence of stress reactions and fractures appears to have been eliminated.
