Analysis of Self-Inflicted Lacerations to the Wrist: A Multi-Disciplinary Approach to Treating

Deep wrist injuries from suicide attempts vs. accidents do not differ regarding sensorimotor outcome, but regarding patient-reported outcome measures

Despite the clinical importance of deep wrist injuries (DWIs), data comparing the outcome of suicide attempt survivors vs. accident survivors are lacking. Patients admitted to our Clinic for acute treatment of a DWI from 2008 to 2016 were contacted for a follow-up assessment of sensory, motor and functional outcomes. Patients also completed the Disability of the Arm, Shoulder and Hand Questionnaire, the Modified Mayo Wrist Score, the Boston Carpal Tunnel Questionnaire, and the WHOQOL-BREF questionnaires. 51 patients could be followed up, on average 4.3 ± 2.9 years after their injury. Suicide attempt survivors did not differ from accidents survivors concerning two-point discrimination, grip and pinch strength, but showed poorer outcomes in self-reported disability, symptom severity, and quality of life. Patients with DWIs from suicide attempts vs. accidents do not differ in sensorimotor outcomes but patient-reported outcome measures. Level of Evidence: II.

Management of Incisional Self-Harm of the Upper Limb: A Systematic Review

Background

The incidence of incisional self-harm of the upper limbs is increasing, and recurrence rates are high. It is not known whether different wound treatment strategies (dressings only vs. surgery) or the operative setting (main theatre vs. non-main theatre) affect wound or mental health-related outcomes.

Methods

Four electronic databases (Ovid MEDLINE, OVID EMBASE, PsycINFO and CENTRAL) were searched from inception to 14/09/2021 for studies which describe the management of incisional self-harm wounds of the upper limb(s) in adults and children. Dual-author screening and data extraction were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Results

In total, 19 studies (1477 patients) were included. Overall, the evidence was limited by a paucity of comparative data on wound management strategy and setting, and poor-quality outcome reporting. Only four studies clearly identified the operative setting for definitive wound management (two in main operating theatres, one in the emergency department and one using both settings, depending on injury severity). Few studies inconsistently reported surgical outcomes (n=9) or mental health outcomes (n=4), hindering evidence synthesis.

Conclusion

Further investigation is needed to determine the most cost-effective management strategies and settings for these injuries.

Hand wounds: An analysis of topography and related damage to underlying structures

INTRODUCTION

Hand wounds account for 35 to 51% of hand traumas. Damage to underlying anatomical structures depends on the location of the wound. The objective of this study is to describe the topographic distribution of hand wounds allowing for subsequent evaluation of the link between affected surface area and underlying lesion.

METHODS

We retrospectively reviewed the medical records of 1058 patients with a total of 1319 wounds over a period of 2 years. Wound location was described according to the cutaneous projection of IFSSH zones for flexors and extensors. Any associated deep lesions were evaluated. Topographical distribution was modeled graphically using a heat-map. We compared the proportion of underlying lesions between each cutaneous zone. Sub-group analysis for lesions' rate regarding zone groups were performed.

RESULTS

58.9% of wounds were located on the palmar surface and 41.1% on the dorsal surface. 71% of wounds affected only the digits. The index finger was the most affected. The most damaged region was zone 2 for palmar wounds and zone 3 for dorsal wounds. 45.5% of wounds resulted in injury to a significant underlying anatomical structure. This frequency was 36.4% and 58.5% for palmar and dorsal wounds respectively. More than 50% of wounds in palmar zone 5 and dorsal zones 1, 3, 5, 6 and 7 presented at least one lesion. A lesion of major structure was more frequently found in palmar zone 5 (p <0.001). Dorsally, no zone predominated. Subgroup analysis for dorsal wounds revealed that wounds overlying joints had more major lesions including more tendons injuries and more articular violations with zone 3 presenting a rate of 68%.

CONCLUSION

We provided the first graphical representation for the topographical distribution of hand wounds. Dorsal wounds have a higher association with injury to underlying structures. These results generally support surgical exploration of all hand wounds regardless of their location.

A pilot study of 17 wrist-cutting suicide injuries in single institution: perspectives from a hand surgeon

Background

Self-cutting is a special type of emergency in hand surgery. Despite its low mortality rate, it is clinically significant because there is a possibility of permanent disability and repeated suicide attempts are likely to occur. Therefore, we aim to understand the characteristics of self-inflicted wrist injuries and share the perspectives from a hand surgeon in order to inform those who face these patients primarily in the emergency room.

Methods

We reviewed 17 patients with self-inflicted wrist injuries who were referred to the Department of Hand surgery from the Emergency Medicine Department from 2013 to 2017. We investigated the differences in demographic features (age, gender, psychological diagnosis, alcohol consumption, prior suicide attempts) and clinical features (injury side, injury pattern, anatomical structures, distance from wrist crease).

Results

Among the patients, 4 were female and 13 were male. 70.6% of patients (12/17) had injuries on the left wrist and 94.1% of patients (16/17) had injuries on the flexor side. The average distance from the wrist crease to the injured site was 3.43 cm and 90.5% (19/21) of total injuries had an average distance of was less than 5 cm. The most frequently injured structures were palmaris longus tendon (58.5%, 10/17). 52.9% (9/17) of patients, among which 6 of the 8 patients with deep injuries and 3 of the 9 patients with superficial injuries, had a history of a psychiatric disorder.

Conclusions

We conclude that a male with a previously diagnosed psychiatric disorder has a higher chance of inflicting a deeper injury. In addition, self-cutting injuries are highly predictable because most of these injuries occur on the flexor side of the left wrist and are limited to a distance of 5 cm from the wrist crease. In terms of the implements used in self-inflicted injuries, we can predict the type of damage to some degree depending on the type of implement used. In view of these characteristics, more appropriate evaluation can be implemented in the emergency room and those who deal with these patients primarily can cope more effectively for better long-term results.
