Abstract

Displaced mid-shaft clavicle fractures have traditionally been treated non-operatively. New evidence supports the use of operative treatment with better functional results although with some risk of adverse complications. The patient's opinion in choosing one or the other option of treatment is important especially when a new therapeutic philosophy is introduced.

We aimed to obtain the patients' preference based on their opinion of various possible outcomes of each treatment method. A clinical decision tree was constructed based on probabilities for various outcomes from the current literature. We used clinical decision analysis based on Bayesian logic. A similar clinical decision analysis was done for a cohort of orthopaedic surgeons.

We interviewed 20 patients to obtain their health preferences on a numerical rating scale for each of the six possible outcomes for the conservative and operative treatments. Similar health preferences were obtained from 20 orthopaedic surgeons.

The cohort of patients were young (age range: 13 – 21, mean: 16 years) males involved in active sport. The results of the decision analysis demonstrated a strong preference for operative management in this cohort of patients (combined probability of 0.81 for operative treatment versus 0.61 for non-operative).

The cohort of orthopaedic surgeons were either career orthopaedic trainees or qualified orthopaedic surgeons with an age range of 28 – 41 years (mean age: 35 years). The results of the decision analysis demonstrated a weak preference for operative management in this cohort of surgeons (combined probability of 0.84 for operative treatment versus 0.77 for non-operative management).

Overall the young active patient is eight times more likely to prefer operative treatment over non-operative management compared to the well informed orthopaedic surgeon. Patient education is the key to a better informed patient who can make a balanced decision. Clinical decision analysis can be a useful tool in this process.

The management of closed ankle fractures requiring open reduction and internal fixation is dependent upon soft tissue swelling to determine the timing of the surgery. At Exeter in 2001 one third of all trauma cases were operated on “out of hours”, in 2007 less than ten percent were principally because of the lack of anaesthetic staff. The senior author has developed a technique of percutaneous ankle fixation that may be undertaken at an early stage despite the presence of swelling.

A retrospective study of four years focusing on time to surgery, time to discharge and complications was compared with a cohort selected at random that had undergone open fixation from the same period. Patients undergoing percutaneous fixation were extracted using the Plato database and all patients were included. Admission documentation, operation notes and subsequent clinic letters were used to ascertain the outcomes. Pre and post-operative imaging was evaluated.

Over a four year period two consultants and four specialist registrars performed the technique on a total of 22 patients. The mean time to surgery was 2.04 days for the percutaneous cohort (range 0–5 days) compared with 4.04 for the open cohort (range 1–10). Time to discharge was 4.6 days to 5.8 in favour of percutaneous. No complications were experienced in the percutaneous cohort compared with 6 patients in the open.

Preliminary results demonstrate a reduced waiting time for surgery and a quicker discharge. Percutaneous fixation is an option when swelling precludes open fixation.
