Abstract
INTRODUCTION: Among various patterns of complex injuries of the wrist and forearm, "spaghetti wrist" refers to an extensive volar forearm laceration, in which several of the 12 tendons, 2 major nerves and 2 major arteries are transected, leading to lifelong disability and psychological, social and economic consequences. The aim of the study is to emphasize the keynote principles for the management of these injuries through retrospective review of a large group of patients treated by a team of experienced hand surgeons. MATERIAL- METHODS: Data were retrospectively obtained for 61 patients (49 males and 12 females with average age of 34.7 years) treated for spaghetti wrist lacerations and followed for a minimum period of two years, in two accredited Orthopaedic / Hand-Upper Extremity Surgery and Microsurgery Departments in Greece. All patients were treated within 16 hours of injury and underwent primary, layered reconstruction of all injured structures through an axial forearm exposure. RESULTS: The most frequent mechanism of injury was glass-related lacerations. Overall, 541 structures were reconstructed, of which 417 were tendons, 76 nerves, and 48 arteries. An average of 8.86 structures were injured per patient, including 6.83 tendons, 1.24 nerves, and 0.79 arteries. The majority of the patients (28/61) had ≥10 structures injured (45.9%), while 32.7% (20/61) and 21.3% (13/61) of patients had 6-9 and 3-5 injured structures respectively. Almost 80% (49/61) of patients had excellent/good grading in all six tests used for the functional assessment post-operatively. DISCUSSION: Spaghetti wrist injuries usually occur in a transverse wound pattern and necessitate timely and definitive operative reconstruction of all injured structures in layers, through an axial approach, by experienced hand surgeons to maximize outcome and to avoid complications. The most important prognostic factor of functional recovery is not the number of transected tendons, but the involvement of ulnar and/or median nerve injury.
