INTRODUCTION
Complex injuries of the upper extremity remain a therapeutic challenge. The prognosis of the damaged extremity is often limited by soft tissue defects. Vacuum Assisted Closure (V.A.C.) therapy facilitates temporary coverage of soft tissue defects prior to surgical reconstruction.
METHODS
In a retrospective study all patients with complex defect injuries of the upper extremity that were treated by V.A.C. prior to reconstruction between August 2003 and September 2005 were analyzed.
RESULTS
7 patients (6 male, 1 female, 14-70 years) were included in the study. The patients suffered from subtotal upper arm (n = 1) and forearm (n = 1) amputation, complex multilevel amputation injury of the forearm (n = 1), slash wound of the forearm with skin defect and discontinuity of all volar structures (n = 1), complex open forearm fractures with skin and soft tissue defects (n = 2), and almost complete necrosis of the flexor compartment following distal radius and proximal ulnar fracture and compartment syndrome (n = 1). Stabile defect coverage was achieved in all patients following V.A.C. therapy by myocutaneous free flaps (n = 2), split thickness skin grafts (STSG) (n = 2), sequential secondary suture (n = 1), and STSG + secondary suture (n = 2). Wound conditions improved significantly under V.A.C. therapy. 5 patients reported pain relief following induction of V.A.C. therapy. Due to reduction of tissue oedema secondary suture was facilitated in 3 patients.
DISCUSSION
V.A.C. therapy represents an essential tool for treatment of complex injuries of the upper extremity with extended soft tissue defects. Decreased frequency of dressing changes as well as reduced tissue oedema considerably improved patient's comfort. Posttraumatic compartment syndrome or skin necrosis, which are often associated with macro amputations of the upper extremity, are efficiently treated with V.A.C., and secondary sutures may be performed despite initial skin defects.
