Background:
Despite the clinical importance of suicidal deep wrist injuries (DWIs), we currently do not know whether their injury patterns differ from accidental injuries.
Methods:
This retrospective study included all patients admitted to the Clinic of Plastic Surgery for acute treatment of a DWI from 2008 to 2016, except for isolated injuries to the palmaris longus (PL) and amputations. Intentionality of the injury was determined using documentation of psychiatric evaluations; cases that could not be categorized regarding intentionality were excluded.
Results:
About 20% of DWIs stemmed from suicide attempts, which involved the nondominant hand in 94.5%. Suicidal DWIs were more likely to involve the median nerve, radial artery, PL, and flexor carpi radialis (FCR), especially on the nondominant hand, but were less likely to involve the ulnar artery and nerve on the dominant hand. The effect of the protective structures PL/flexor carpi ulnaris on the median nerve/ulnar artery could be confirmed for suicidal DWIs, but intactness of the FCR was associated with increased radial artery injuries. Longitudinal cut orientation in suicidal DWIs was associated with more radial artery injuries, but fewer injuries to tendons and nerves. Frequencies of various other injury constellations are tabulated to aid in clinical assessment.
Conclusions:
Suicidal and accidental DWIs differed in various aspects of injury pattern. Suicidal injuries were mostly localized to the nondominant radial side, and accidental injuries to the ulnar side. Also, the so-called protective structure FCR had the opposite effect in suicidal injuries. Thus, findings regarding injury patterns in accidental DWIs cannot be generalized to suicidal injuries.
Objective
As suicide attempts by definition entail at least some threat to physical integrity and life, they theoretically qualify as an A1 criterion for posttraumatic stress disorder (PTSD). This study uses the unique opportunity of deep wrist injuries to quantify the effect of intentionality on PTSD rates by comparing suicide attempt survivors with patients who sustained accidental injuries similar in mechanism, localization, and extent.
Method
Patients who had been admitted with an acute deep wrist injury from 2008 to 2016 filled out the revised Impact of Event Scale and reported other known PTSD risk factors. Mental morbidity and intentionality of the injury were determined by psychiatric consultation during the index hospitalization.
Results
Fifty‐one patients were followed up (72.5% male, 92.2% Caucasian, mean age at injury 42.3 ± 17.5 years, 72.5% accidental injuries), on average 4.2 ± 2.9 years after their injury. The intentionality of the injury alone predicted the severity of intrusions, avoidance, hyperarousal, and probable PTSD (aOR = 14.0).
Conclusions
Traumatization in the context of a suicide attempt may be a hitherto unknown PTSD risk factor. Patients after suicide attempts, especially medically serious attempts, should be monitored for PTSD symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
