Recent changes in the pattern of hand injuries in Hong Kong: a regional hospital survey.

Adult inpatients with injuries to the hand admitted to the Department of Orthopaedics and Traumatology of the Prince of Wales Hospital, Hong Kong, from June 1992 to May 1993 were surveyed (n=533). The causes of injury, mechanisms involved, and the nature of injuries were recorded. The injuries were further graded according to four different scales. It was found that 65% of the injuries were sustained at work, 15% in domestic environments, 7.6% during sports or recreational activities, and 6.5% in traffic accidents. Injuries caused by heavy machinery amounted to 26.7% and the electric saw was the second most common cause of injury accounting for 9.4% of injuries. Crush injuries occurred in 37.8%. The incidence of hand injury is estimated to be 600 per 100,000 population annually. The pattern of hand injuries bears some similarities and differences to published series. A comparison with data obtained in Hong Kong in the 1970s shows that major changes have occurred. We need continual surveillance of hand injury patterns.
