BACKGROUND: Spaghetti wrist injuries involve a complete transection of three or more structures at the wrist level (including tendons, nerves, or arteries). Few studies on spaghetti wrist trauma have been reported in the literature, and most of them have focused on functional recovery rather than the prognostic factors which affect the outcome. We attempted to address some of the lacunae in current knowledge.
METHODS: Patients who were operated between January 2017 to January 2019 for spaghetti wrist injuries at a level 1 trauma center were included in the study. Several variables such as age, gender, smoking, education level, mechanism of injury, time gap between the injury to surgery, number of damaged structures and pattern of neurovascular structure were selected as potential prognostic factors to be included in the analysis. Motor recovery, sensory recovery & QuickDash score were used for the outcome assessment. A Multivariate analysis was done to identify the prognostic factor(s).
RESULTS: Thirty patients were included in the study. The mean age was 30.5 years (range: 7-57 years). Male population was predominantly affected (93.33%). The dominant limb was injured in 73.33%. The most common mechanism of injury was accidental glass cut (n = 19,63.33%), the most frequently affected structure was flexor digitorum superficialis of the middle finger (n = 23, 76.6%). Combined nerve injury was present in 23.33%. Intrinsic muscle recovery was affected significantly by presence of crush injury (e = 7.189, std error = 2.425, p = 0.003), education significantly affected power grip recovery (p < 0.0001), age was associated with pinch grip recovery (e = 0.083, std error = 0.039, p = 0.034).
CONCLUSIONS: Increasing age, low education level, and presence of crush injury were identified as negative prognostic factors in the study. These findings may be used for counselling of patients affected by spaghetti wrist injuries.
