The diagnostic accuracy of clinical examination in hand lacerations.

INTRODUCTION

Hand injuries account for a significant proportion of emergency department attendance. We investigated the diagnostic accuracy of clinical examination in patients with simple hand lacerations undergoing surgical exploration at our unit.

METHODS

One hundred and sixty-five consecutive patients were identified as undergoing exploration of the hand. Case notes of these patients were reviewed. The clinical findings, made by emergency department doctors (ED) and hand surgeons (HS), were compared with the operative findings.

RESULTS

A total of 101 patients were included following exclusion criteria. Both ED and HS correctly identified 68.2% of flexor tendon injuries. Overall, the ED diagnosed accurately significantly fewer extensor tendon injuries (ED 65.6% vs HS 75.0%, p<0.001). Similarly, HS diagnosed nerve injuries more accurately than ED (ED 54.5% vs HS 78.8%, p<0.005).

DISCUSSION

Clinical examination forms an important part of the patient assessment, provides the surgeon with an idea of which structures are potentially injured, and its value should never be underestimated. Formal exploration, however, should be undertaken since both ED and HS missed about 30% injuries.
