Abstract

Purpose: To characterize the common patterns of injury in detail in cases of blast injuries to the hand and to outline the possible pathomechanics of these patterns of injury while describing the treatment modalities for the same as practiced in our center.

Materials and methods: A review of admitted patients in our department from september 2009 through december 2010 of blast injuries to the hand was made. Each patient had a careful characterization of their injuries as mild, moderate or severe with the help of X-rays, clinical photographs and operative notes. The treatment of these patients during hospital stay was also documented.

Results: Of the 55 patients studied, 5 patients suffered mild injuries with no bony injuries or dislocations, 26 patients had moderate injuries characterized by fractures and dislocations in addition to soft tissue injuries and 24 patients had severe injuries characterized by variable degrees of amputations. The most common injury type was to the radial aspect of the hand characterized by a first web split and a dislocation of the CMC joint of the thumb associated with fracture of the central metacarpals and amputations of the index and long fingers in some cases. Injury to the ulnar aspect was rare. Injuries were treated by repair as well as replacement done mostly in a serial fashion.

Conclusion: Depending on the mode of injury, blast injuries to the hand can have varying patterns of injury, which can have important implications in the treatment and rehabilitation of a patient.

Keywords: Blast; hand; injury; pathomechanics; pattern.
