Measurement properties of the Patient-Rated Wrist and Hand Evaluation: Rasch analysis of responses from a traumatic hand injury population

INTRODUCTION

The Patient-Rated Wrist and Hand Evaluation (PRWHE) is a self-reported assessment of pain and disability to evaluate outcome after hand injuries. Rasch analysis is an alternative strategy for examining the psychometric properties of a measurement scale based in item response theory, rather than classical test theory.

PURPOSE OF THE STUDY

This study used Rasch analysis to examine the content, scoring and measurement properties of the PRWHE.

METHODS

PRWHE scores (n = 264) from persons with a traumatic injury or reconstructive surgery to one hand were collected from an outpatient hand rehabilitation facility. Rasch analysis was conducted to assess how the PRWHE fit the Rasch model, confirms the scaling structure of the pain and disability subscales, and identifies any areas of bias from differential item functioning.

RESULTS

Rasch analysis of the PRWHE supports internal consistency of the scale (α = 0.96) and reliability (as measured by the person separation index) of 0.95. While gender, age, diagnosis, and duration since injury all systematically influenced how people scored the PRWHE, hand dominance and affected side did not. Rasch analysis supported a 3 subscale structure (pain, specific activities and usual activities) rather than the current divisions of pain and disability.

CONCLUSIONS

Initial examination of the PRWHE indicates the psychometric properties of consistency, reliability and responsiveness previously tested by classical methods are further supported by Rasch analysis. It also suggests the scale structure may be best considered as 3 subscales rather than simply pain and disability.

Do patient-reported outcome measures capture functioning aspects and environmental factors important to individuals with injuries or disorders of the hand?

STUDY DESIGN

Qualitative study.

INTRODUCTION

Clinical outcome evaluation needs to consider the patient perspective for an in-depth understanding of functioning and disability.

PURPOSE OF THE STUDY

To explore whether patient-reported outcome measures (PROMs) used in the field of hand injuries or hand disorders, capture functioning aspects and environmental factors important to the patients.

METHODS

We performed a qualitative study and a systematic literature review. The focus group sessions were recorded, transcribed verbatim, and the identified concepts were linked to the ICF. We searched in MEDLINE for reviews, related to injuries or disorders of the hand, reporting on PROMs. We linked the items of the identified PROMs to the ICF and compared the qualitative data with the content of the PROMs.

RESULTS

Statements from 45 individuals who participated in eight focus groups were linked to 97 categories of the ICF. From 15 reviews included, eight PROMs were selected. The selected PROMs capture 34 of the categories retrieved from the qualitative data.

CONCLUSIONS

PROMs used in the context of hand injuries or hand disorders capture only in parts the functioning aspects important to the patients.

Integration of occupation based intervention in hand injury rehabilitation: A Randomized Controlled Trial

STUDY DESIGN

Randomized Controlled Trial (RCT).

INTRODUCTION

Engagement in daily occupations and day to day activities helps to restore function in individuals with injured hands and provides a platform to practise selected occupations.

PURPOSE

The purpose of this study was to investigate the effectiveness of a combination of Occupation Based Intervention (OBI) and Therapeutic Exercise (TE) compared to TE alone for the rehabilitation of hand injuries.

METHOD

A single center RCT, parallel group was conducted at the Kuala Lumpur General Hospital (KLGH), Malaysia. Forty-six adult clients with hand injuries who consented to participate were randomly allocated to either the OBI + TE group or to the TE group.

RESULTS

Following a ten week intervention program, statistical significance differences were found in DASH score (TE = 18.64 ± 14.84 vs OBI + TE = 9.50 ± 9.14, p = 0.02); total active motion (TE = 1035.85 ± 179.84 vs OBI + TE = 1203.65 ± 133.60, p = 0.01); neuropathic pain (TE = 2.90 ± 2.79 vs OBI + TE = 1.05 ± 2.01, p = 0.02); COPM performance (TE = 7.62 ± 2.03 vs OBI + TE = 9.53 ± 0.64, p < 0.001); and COPM satisfaction (TE = 7.60 ± 2.11 vs OBI + TE = 9.49 ± 0.76, p < 0.001) in favor of OBI + TE group.

CONCLUSION

This study highlighted the integration of OBI into hand injury rehabilitation improved outcomes for clients.

Functional, motor, and sensory assessment instruments upon nerve repair in adult hands: systematic review of psychometric properties

BACKGROUND

Outcome after nerve repair of the hand needs standardized psychometrically robust measures. We aimed to systematically review the psychometric properties of available functional, motor, and sensory assessment instruments after nerve repair.

METHODS

This systematic review of health measurement instruments searched databases from 1966 to 2017. Pairs of raters conducted data extraction and quality assessment using a structured tool for clinical measurement studies. Kappa correlation was used to define the agreement prior to consensus for individual items, and intraclass correlation coefficient (ICC) was used to assess reliability between raters. A narrative synthesis described quality and content of the evidence.

RESULTS

Sixteen studies were included for final critical appraisal scores. Kappa ranged from 0.31 to 0.82 and ICC was 0.81. Motor domain had manual muscle testing with Kappa from 0.72 to 0.93 and a dynamometer ICC reliability between 0.92 and 0.98. Sensory domain had touch threshold Semmes-Weinstein monofilaments (SWM) as the most responsive measure while two-point discrimination (2PD) was the least responsive (effect size 1.2 and 0.1). A stereognosis test, Shape and Texture Identification (STI), had Kappa test-retest reliability of 0.79 and inter-rater reliability of 0.61, with excellent sensibility and specificity. Manual tactile test had moderate to mild correlation with 2PD and SWM. Function domain presented Rosén-Lundborg score with Spearman correlations of 0.83 for total score. Patient-reported outcomes measurements had ICC of 0.85 and internal consistency from 0.88 to 0.96 with Patient-Rated Wrist and Hand Evaluation with higher score for reliability and Spearman correlation between 0.38 and 0.89 for validity.

CONCLUSIONS

Few studies included nerve repair in their sample for the psychometric analysis of outcome measures, so moderate evidence could be confirmed. Manual muscle test and Rotterdam Intrinsic Hand Myometer dynamometer had excellent reliability but insufficient data on validity or responsiveness. Touch threshold testing was more responsive than 2PD test. The locognosia test and STI had limited but positive supporting data related to validity. Rosén-Lundborg score had emerging evidence of reliability and validity as a comprehensive outcome following nerve repair. Few questionnaires were considered reliable and valid to assess cold intolerance. There is no patient-reported outcome measurement following nerve repair that provides comprehensive assessment of symptoms and function by patient perspective.

Trends of hand injuries presenting to US emergency departments: A 10-year national analysis

BACKGROUND

The purpose was to observe current incidence and trends of hand and wrist injuries presenting to U.S. emergency departments (EDs) over a decade.

METHODS

The National Electronic Injury Surveillance System (NEISS) was queried for hand and wrist injuries from January 2009-December 2018. Descriptive analyses were used to report injury types to the hand and wrist. Incidence, age, gender, race, injury location, and type of injury were recorded. Linear regression analyses were used to assess changes in trends over time. A p value <0.05 was statistically significant.

RESULTS

In total, 649,131 cases of hand and wrist injuries were identified in the NEISS from 2009 to 2018, correlating to 25,666,596 patients nationally. Incidence rates for finger, hand, and wrist were 450, 264, and 182 per 100,000 people. The estimated number of patients per year declined by 8.6% from 2009 to 2018. Male adults (aged 18-39) were the most frequent demographic. Total national estimates of hand (-8.2%; p = 0.001), wrist (-6.1%; p = 0.007), and finger (-9.9%; p < 0.001) injuries declined over the study period. The most common injuries were lacerations (36.5%), fractures (19.9%), strains/sprains (12.3%), and contusions/abrasions (12.1%) which significantly declined over the study period. The overall admission rate was 1.8%.

CONCLUSIONS

The estimated annual number of hand/wrist injuries presenting to US EDs was 2.6 million with gradual decline over the decade. Hand injury registries could assist in quality improvement measures targeted toward increased efficiency and resource allocation and education.

Conclusion

Knowledge of these entities and special consideration for the athlete can help the team physician effectively treat these players and help them achieve their goals.

Investigation of reliability, validity, and cutoff value of the Jebsen-Taylor Hand Function Test

STUDY DESIGN

This is a cross-sectional study.

INTRODUCTION

The Jebsen-Taylor Hand Function Test (JTHFT) evaluate the efficacy of treatment and assess a broad range of hand functions.

PURPOSE OF THE STUDY

The purpose of this study was to investigate the psychometric properties of the JTHFT and to determine cutoff values.

METHODS

The test-retest reliability was assessed by determining intraclass correlation coefficient (ICC), the hypothesis testing validity was assessed by using Spearman rho coefficient, and the receiver operating characteristic curve, area under the curve of the receiver operating characteristic, sensitivity, and specificity were calculated to determine the cutoff values. We administered JTHFT, Disabilities of Arm, Shoulder and Hand Questionnaire (DASH) and assessed grip strength with Jamar dynamometer. We included 162 healthy participants and 143 patients with hand injuries.

RESULTS

The JTHFT subtests and total score have a good to excellent test-retest reliability (except lifting large light object for dominant hand-ICC: 0.77) for both dominant and nondominant hand (ICCs = 0.84-0.97). There was a statistically significant, weak positive correlation between the JTHFT total score and DASH-T (r = 0.39, P < .001 for the injured hand; r = 0.35, P < .001 for the uninjured hand) and also statistically significant weak negative correlation between grip strength for injured hand and JTHFT total score for injured hand (r = -0.33; P < .001). The cutoff value of the total score was found to be 37.08 s for injured hand.

DISCUSSION AND CONCLUSION

JTHFT is a reliable and valid instrument. Clinicians and researchers may use this test with confidence to assess the dexterity of hand injury patients.

Zone 2 flexor tendon injuries: Venturing into the no man's land

Flexor tendon injuries are seen commonly yet the management protocols are still widely debated. The advances in suture techniques, better understanding of the tendon morphology and its biomechanics have resulted in better outcomes. There has been a trend toward the active mobilization protocols with development of multistrand core suture techniques. Zone 2 injuries remain an enigma for the hand surgeons even today but the outcome results have definitely improved. Biomolecular modulation of tendon repair and tissue engineering are now the upcoming fields for future research. This review article focuses on the current concepts in the management of flexor tendon injuries in zone 2.

Cost analysis and related factors in patients with traumatic hand injury

The aim of this study was to measure the direct and indirect costs and factors influencing these costs in patients presenting following traumatic hand injury. We assessed patients aged 18-65 years who were in work. Hand injury severity and functional status were assessed. Direct costs, including medical care expenses, and indirect costs, including lost productivity, were calculated. Seventy-nine patients of a mean age of 32 years were included. The mean direct cost for each patient was $1772 (47% of total cost), and the indirect cost was $1891 (53% of total cost). Injury severity, time to return to work, and hospitalization time were the main parameters of increased total cost in a linear regression analysis.

Epidemiology of complex hand injuries treated in the Plastic Surgery Department of a tertiary referral hospital in Warsaw

Background

Trauma to the hand is common and potentially serious, impairing daily living and general quality of life. Patients are often unable to work for several months, with hand function improving only gradually. Here, we review the epidemiology of hand injuries treated at a tertiary referral hospital in Warsaw, Poland.

Material and methods

In this single-centre, retrospective study, we reviewed medical records of patients presenting to the A&E Unit of the Plastic Surgery Department, Centre of Postgraduate Medical Education in Warsaw, Poland, between January 2001 and December 2005. We assessed a number of patient and injury characteristics, including severity, scored with the Hand Injury Severity Scoring System (HISS), and time off work.

Results

Of 1091 patients with a hand injury, 84% were male and over half were under the age of 40 years. Hand injury commonly resulted in tendon damage (56.1%), especially to finger flexors (79%), and in skin loss (37.8%). Amputations occurred in 24.1% of cases, while fractures (9.6%) and nerve (6.1%) or joint (5.5%) damage were less common. HISS-graded injury severity was moderate in 28.6% of cases, over half of the patients suffered severe (25.5%) or major (26.5%) injuries, and minor injuries were relatively uncommon (19.4%).

Conclusions

Amongst patients admitted to our Department, the most common injuries were tendon damage, skin loss, and amputations. Over half of the patients presented with severe or major injuries and took six months or longer to return to work, suggesting they were likely to face substantial social and economic consequences of their injury.

The use of split-thickness versus full-thickness skin graft to resurface volar aspect of pediatric burned hands: A systematic review

OBJECTIVE

The aim of this systematic review was to discuss the comparison of split-thickness skin graft (STSG) and full-thickness skin graft (FTSG) use as the treatment for volar digital and palmar burns in children.

METHODS

We conducted PubMed and Cochrane Library searches using keywords "hand injuries", "contracture" and "skin transplantation". The search was limited to studies published from 1st January 1980 until 31st December 2013 and used English language. We selected the studies based on specific inclusion and exclusion criteria. We assessed the quality of the studies by using Newcastle-Ottawa Scale (NOS) for cohort studies.

RESULTS

We included eight articles in our systematic review. One of those studies is a prospective cohort study and the others are retrospective cohort studies. Based on combined range of motion (ROM) evaluation in three studies, STSG group yielded poorer functional outcomes than FTSG group. However, there is no study which can fairly show that FTSG was significantly superior to STSG to achieve good functional outcomes.

CONCLUSION

Currently, there is no strong, high-quality evidence to prove that FTSG is superior to STSG to cover pediatric palmar burns. Either FTSG or STSG can be utilized with consideration of several influential factors especially splinting and physiotherapy.

Fractures and dislocations of the hand in polytrauma patients: Incidence, injury pattern and functional outcome

INTRODUCTION

Injuries of the hand can cause significant functional impairment, diminished quality of life and delayed return to work. However, the incidence and functional outcome of hand injuries in polytrauma patients is currently unknown. The aim of this study was to determine the incidence, distribution and functional outcome of fractures and dislocation of the hand in polytrauma patients.

METHODS

A single centre retrospective cohort study was performed at a level 1 trauma centre. Polytrauma was defined as patients with an Injury Severity Score of 16 or higher. Fractures and dislocations to the hand were determined. All eligible polytrauma patients with hand injuries were included and a Quick Disability of Arm, Shoulder and Hand questionnaire (QDASH) and Patient-Rated Wrist/Hand Evaluation (PRWHE) were administered. Patients were contacted 1-6 years after trauma.

RESULTS

In a cohort of 2046 polytrauma patients 72 patients (3.5%) suffered a hand injury. The functional outcome scores of 52 patients (72%) were obtained. The Metacarpal (48%) and carpal (33%) bones were the most frequently affected. The median QDASH score for all patients with hand injury was 17 (IQR 0-31) and the PRWHE 14 (IQR 0-41). Patients with a concomitant upper extremity injury (p=0.002 for PRWHE, p0.006 for QDASH) and those with higher ISS scores (p=0.034 for PRWHE, QDASH not significant) had worse functional outcome scores. As an example, of the 5 patients with the worst outcome scores 3 suffered an isolated phalangeal injury, all had concomitant upper extremity injury or neurological injuries (3 plexus injuries, 1 severe brain injury).

CONCLUSION

The incidence of hand injuries in polytrauma patients is 3.5%, which is relatively low compared to a general trauma population. Metacarpal and carpal bones were most frequently affected. The functional extremity specific outcome scores are highly influenced by concomitant injuries (upper extremity injuries, neurological injuries and higher ISS).

Analysis of 344 Hand Injuries in a Pediatric Population

Background

The purpose of this study was to identify comprehensive hand injury patterns in different pediatric age groups and to assess their risk factors.

Methods

This retrospective study was conducted among patients younger than 16-year-old who presented to the emergency room of a general hospital located in Gyeonggi-do, Republic of Korea, and were treated for an injury of the finger or hand from January 2010 to December 2014. The authors analyzed the medical records of 344 patients. Age was categorized according to five groups.

Results

A total of 391 injury sites of 344 patients were evaluated for this study. Overall and in each group, male patients were in the majority. With regard to dominant or non-dominant hand involvement, there were no significant differences. Door-related injuries were the most common cause in the age groups of 0 to 3, 4 to 6, and 7 to 9 years. Sport/recreational activities or physical conflict injuries were the most common cause in those aged 10 to 12 and 13 to 15. Amputation and crushing injury was the most common type in those aged 0 to 3 and 4 to 6 years. However, in those aged 10 to 12 and 13 to 15, deep laceration and closed fracture was the most common type. With increasing age, closed injuries tended to increase more sharply than open injuries, extensor tendon rupture more than flexor injuries, and the level of injury moved proximally.

Conclusions

This study provides a comprehensive overview of the epidemiology of hand injuries in the pediatric population.

Wide-awake local anaesthesia no tourniquet (WALANT) vs regional or general anaesthesia for flexor tendon repair in adults: protocol for a systematic review and meta-analysis

BACKGROUND

Flexor tendon injuries most commonly occur following a penetrating injury to the hand or wrist. These are challenging injuries and the standard treatment is surgical repair under general or regional anaesthesia. 'Wide-awake' surgery is an emerging technique in hand surgery where a conscious patient is operated on under local anaesthetic. The vasoconstrictive effect of adrenaline (epinephrine) creates a 'bloodless' operating field and a tourniquet is not required. The potential advantages include intra-operative testing of the repair; removal of the risks of general anaesthesia; reduced costs; no aerosol generation from intubation therefore reduced risk of COVID-19 spread to healthcare professionals. The aim of this study will be to systematically evaluate the evidence to determine if wide-awake surgery is superior to general/regional anaesthetic in adults who undergo flexor tendon repair.

METHODS

We designed and registered a study protocol for a systematic review and meta-analysis of comparative and non-comparative studies. The primary outcome will be functional active range of motion. Secondary outcomes will be complications, resource use (operative time) and patient-reported outcome measures. A comprehensive literature search will be conducted (from 1946 to present) in MEDLINE, EMBASE, CINAHL, and Cochrane Library. Grey literature will be identified through Open Grey, dissertation databases and clinical trials registers. All studies on wide-awake surgery for flexor tendon repair will be included. The comparator will be general or regional anaesthesia. No limitations will be imposed on peer review status or language of publication. Two investigators will independently screen all citations, full-text articles and abstract data. Potential conflicts will be resolved through discussion or referral to a third author when necessary. The study methodological quality (or bias) will be appraised using an appropriate tool. If feasible, we will conduct a random effects meta-analysis.

DISCUSSION

This systematic review will summarise the best available evidence and definitively establish if function, complications, cost, or patient-reported outcomes are improved when flexor tendons are repaired using wide-awake technique. It will determine if this novel approach is superior to general or regional anaesthesia. This knowledge will help guide hand surgeons by continuing to improve outcomes from flexor tendon injuries.

Demographic profile of hand injuries in an industrial town of north India: a review of 436 patients

There are not many injuries that rival the injured hand in complexity. A better understanding of biologic, behavioral, and socioeconomic risk factors potentially associated with hand injuries can help identify those individuals most at risk and define potential preventative measures to help reduce the incidence. We present a prospective study of 436 consecutive patients of hand and forearm injury treated over a period of 2 years. A serial recording of the demographic profile of the patient along with the type & cause of injury sustained, hand dominance, duration of hospital stay, time lag between injury and admission, type surgery preformed with intra-operative findings and the cost analysis was done. An expected male dominance in economically viable individuals of 21 to 30 years formed 50 % of the patients of which 22.9 % were labourers and students each. The malady was altercation (27.5 %) followed by industrial & road accidents. Post prandial period was most notorious with multiple neuro (27.05 %) vasculo (39.34 %) tendinous (60.66 %) injury common with even simple lacerations. Dominant hand injury was commonest. It is challenging to assess and treat an injured hand. This study defines the demography and the etiology behind the various cases of hand and forearm injury with the detailed trauma profile. The limitation of the study was absence of functional outcome. The necessity of hand trauma registry is a pre-requisite to quantify the burden of hand injuries and formulate a prevention strategy.

Transitioning from hurting to healing: self-management after distal radius fracture

PURPOSE

Chronic pain and disability after musculoskeletal trauma support the need for non-biomedical perspectives to frame experiences of recovery. Self-management is a specific holistic lens with implications for improving health outcomes. This qualitative study explored how adults made meaning of self-management after distal radius fracture (DRF).

METHODS

Thirty-one individuals aged 45-72 with a unilateral DRF participated in a semi-structured interview 2-4 weeks after discontinuing full-time wrist immobilization. Interviews were audio-recorded and transcribed, and constructivist grounded theory techniques were used to analyze the data.

RESULTS

Participants made meaning of self-management as a process of "transitioning from hurting to healing," which occurred via three underlying processes. "Learning because of my injury" included gaining information for empowerment and understanding by physically living through the experience. "Working and hoping toward healing" involved taking active steps to recovery in the face of uncertainty. "Getting back to my normal self" comprised reconnecting to one's body and identity after injury.

CONCLUSIONS

Participants' lived experiences overlapped with those of self-managing chronic conditions, highlighting the need to consider how individuals actively engage in their recovery after DRF. Findings suggest using supportive interventions to facilitate patients' understanding, activation, and engagement in meaningful activity after DRF.Implication for rehabilitationTo maximize health outcomes after distal radius fracture, clinicians should move beyond impairment remediation to supporting multiple dimensions of recovery, including emotional distress and functional limitations.Clinicians should routinely provide early and ongoing information, such as expected symptoms and recovery time frames, to minimize loss of control related to uncertainty.Clinicians should emphasize active interventions, such as collaborative goal setting and functional tasks, that engage patients in their own healing.Clinicians should support patients' early return to meaningful activity to maintain or restore connection to the body and identity.

Simplified internal fixation of fifth metacarpal neck fractures

BACKGROUND

Fifth metacarpal neck fractures (boxer's fractures) are common injuries that contribute 20% of all hand fractures. Divergent percutaneous pinning (bouquet fixation) as described by Foucher has gained popularity but is challenging and at times arduous, as it requires the insertion of several slender K-wires into a narrow medullary canal. Here, we report on a simplified technique in which a single thick K-wire is inserted.

TECHNIQUE

An 18/10 K-wire is bent at one end then mounted on a drill chuck. The incision is performed and the entry hole created using the K-wire, which is then advanced along the medullary canal. After reduction of the metacarpal head using the Jahss manoeuvre, the K-wire is inserted across the fracture site into the subchondral bone. Any persistent rotational malalignment is corrected by rotating the metacarpal around the K-wire. Immobilisation is by buddy taping covered by a resin guard.

METHODS

We collected follow-up data for 30 patients treated using our technique, at a mean age of 32 years.

RESULTS

90 days after surgery, the fracture was healed in all patients. No patients had rotational malalignment. Mean operative time was 14minutes. No complications were recorded.

DISCUSSION

The use of a single thick K-wire proved simple, effective, reproducible, and rapid. No rotational malalignment occurred. This technique is faster and easier to perform than divergent pinning with multiple K-wires.

CONCLUSION

This technique can be used to treat fifth metacarpal neck fractures.

Reversed posterior interosseous flap: safe and easy method for hand reconstruction

Complex hand trauma presents multifaceted problems for the surgeon. Soft tissue defects of the upper extremity must be carefully assessed to determine the most appropriate method of coverage of hand. In this article, the reversed posterior interosseous flap was used for coverage of the hand. The injured areas include: dorsum of the hand (10 cases), the wrist (3 cases) and the dorsal thumb (2 cases). All flaps survived completely and none exhibited venous compromise. All donor sites were skin grafted. The reversed posterior interosseous flap is a versatile option for coverage of moderate sized defects of the hand and is specifically indicated for coverage of injuries of the wrist, dorsal hand and dorsal thumb.

Factors affecting time off work in patients with traumatic hand injuries-A bio-psycho-social perspective

Hand injuries are common and can result in a long time off work. To analyse and identify factors affecting time of work, a holistic view on patients is needed. World Health Organization's International Classification of Functioning, Disability and Health (ICF) with its bio-psycho-social perspective provides such a holistic view. The purpose of this study is to analyse time off work in patients with traumatic hand injuries and to identify factors affecting time off work from a bio-psycho-social perspective. We used factors derived from the ICF Core Set for Hand Conditions to predict time off work by applying Cox regression analyses and Kaplan-Meier method using data of a multicentre prospective study in nine German Level 1 hand trauma centres. In total, 231 study participants with a broad range of hand injuries were included. From these, 178 patients (77%) returned to work within 200 days. Impairments in mobility of joint functions and sensory functions related to temperature and other stimuli as well as higher hand strain at work led to extended time off work. Gender, fine hand use and employment status additionally influenced time off work in sub-models. Our results demonstrate that a bio-psycho-social perspective is recommended when investigating time off work.

Risk of surgical site infection in hand trauma, and the impact of the SARS-CoV-2 pandemic: A cohort study

BACKGROUND

Despite the ubiquity of hand trauma, there remains insufficient published data to reliably inform these patients of surgical site infection (SSI) risk. We describe the risk of SSI in a single-centre cohort of patients with hand trauma, with an analysis of the impact of the coronavirus disease-2019 (COVID-19) pandemic.

METHODS

Retrospective data collection of consecutive patients who underwent surgery for hand and wrist trauma in a single plastic surgery centre over two, three-month periods. Demographic, injury and operative details, alongside prophylactic antibiotic use, were recorded. Burn injuries and wounds infected at presentation were excluded. Presence of SSI at 30 days (90 days if a surgical implant was used) was assessed.

RESULTS

Overall, 556 patients - 'Pre-COVID-19' (n = 310) and 'During COVID-19' (n = 246) - were included. Risk of SSI was 3.6% in the aggregated cohort. Female patients were more likely to develop an SSI, even when adjusted for their greater prevalence of bite aetiologies (adj OR 2.5; 95% CI, 1.00-6.37 and p < 0.05). The absolute risk of SSI in the 'Pre-COVID-19' group was 2.3% and 5.3% in the 'During COVID-19' group. The relative risk of developing an SSI in the 'During COVID-19' group was 2.34 (95% CI, 0.95-5.78 and p = 0.06). Baseline characteristics were equivalent between the two groups.

CONCLUSION

The risk of SSI in hand trauma is the same as the nationally estimated risk for all surgeries; 3-5%. Changes in presentation and practice associated with the first wave of the COVID-19 pandemic did not appear to alter the risk of SSI in patients undergoing surgery for hand trauma.

Purple Glove Syndrome after Phenytoin or Fosphenytoin Administration: Review of Reported Cases and Recommendations for Prevention

The aim of our study was to identify all previously reported cases of phenytoin- or fosphenytoin-associated purple glove syndrome (PGS) and summarize the most current understanding of the pathophysiology, clinical presentation, diagnosis, and treatment of the disease. We searched the English language references from MEDLINE, EMBASE, CINAHL, TOXNET, and gray literature that featured one or more case descriptions of phenytoin- or fosphenytoin-associated PGS after administration and provided information on the clinical setting of the event and associated outcome(s). Descriptive statistics were employed to summarize relevant facts about the cases. We identified 82 unique cases of parenteral phenytoin-associated PGS and 5 cases of fosphenytoin-associated PGS that were published from 1984 to 2015. Additionally, we found two cases of PGS associated with oral formulation of phenytoin published from 1999 to 2015. The spectrum of tissue injury ranged from mild local cutaneous reactions around the infusion site to frank limb ischemia. Just over a half of cases reported symptoms after one dose of IV phenytoin. Pathologic findings included evidence for microvascular thrombosis and possible microvascular or subclinical extravasation as a contributing mechanism. Dopper ultrasound and conventional angiography were used in some patients to identify arterial or venous thrombosis. Various treatments were documented including the use of supportive care such as limb elevation and heat or cold application, utilization of systemic antibiotics, anticoagulants, or vasodilators, and local infiltration of hyaluronidase, heparin, or other compounds. In a small number of patients, invasive interventions such as regional anesthesia, thrombectomy, fasciotomy, and debridement were described. Time to resolution varied from days to weeks. Resolution of PGS without deficits was documented in the majority of cases. Skin changes followed by sensory and motor deficits were described in 16, 6, and 5 cases, respectively. Four patients underwent skin grafting and eight patients required limb amputation. Death as a result of PGS was documented in two patients. PGS associated with oral and injectable phenytoin or parenteral fosphenytoin has been documented in the literature and sometimes includes significant vascular thrombosis and potentially limb-threatening ischemia. Avoidance of small hand veins, adherence to recommended IV administration guidelines and monitoring of the infusion site for reactions should be considered to decrease the morbidity of IV phenytoin or fosphenytoin use. Patients with PGS and evidence of decreased distal perfusion should undergo prompt vascular imaging and potential intervention to avoid ischemic sequelae. Alternative anticonvulsant drugs should be considered in patients at risk for PGS when possible.

Particularities of hand and wrist complex injuries in polytrauma management

Hand and wrist lesions are relatively common in polytraumatised patients. These subjects sustain a wide range of potential life-threatening conditions and hand and wrist injuries incurred are often not diagnosed or are insufficiently treated. Closed lesions are the most frequently missed diagnosis, but even severe open lesions may be incorrectly treated. Most of these hand and wrist injuries can have a strong negative impact on long-term quality of life, particularly when treatment of these injuries is poor or delayed. Orthopaedic and hand surgeons should be vigilant in their assessment and treatment of patients with multiple injuries and a global approach, based on the advanced trauma life support (ATLS)-protocol, must be applied. The very common association of head, chest, abdomen, bone and soft-tissue lesions in the polytraumatised patient requires a multidisciplinary team approach from the beginning. The energy of trauma in these patients often causes complex injuries to the wrist and hand; these require correct treatment in terms of both timing and techniques. It is not possible to create a practical, useful guideline with a "one lesion-one solution" approach, because every case is different; therefore, this paper describes a spectrum of indications and techniques that may be useful in managing hand and wrist injuries, particularly in polytraumatised patients.

Multimodal care for the management of musculoskeletal disorders of the elbow, forearm, wrist and hand: a systematic review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration

BACKGROUND

Musculoskeletal disorders of the elbow, forearm, wrist and hand are associated with pain, functional impairment and decreased productivity in the general population. Combining several interventions in a multimodal program of care is reflective of current clinical practice; however there is limited evidence to support its effectiveness. The purpose of our review was to investigate the effectiveness of multimodal care for the management of musculoskeletal disorders of the elbow, forearm, wrist and hand on self-rated recovery, functional recovery, or clinical outcomes in adults or children.

METHODS

We conducted a systematic review of the literature and best evidence synthesis. We searched MEDLINE, EMBASE, CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials from January 1990 to March 2015. Randomized controlled trials, cohort studies, and case-control studies were eligible. Random pairs of independent reviewers screened studies for relevance and critically appraised relevant studies using the Scottish Intercollegiate Guidelines Network criteria. Studies with a low risk of bias were synthesized following best evidence synthesis principles.

RESULTS

We screened 5989 articles, and critically appraised eleven articles. Of those, seven had a low risk of bias; one addressed carpal tunnel syndrome and six addressed lateral epicondylitis. Our search did not identify any low risk of bias studies examining the effectiveness of multimodal care for the management of other musculoskeletal disorders of the elbow, forearm, wrist or hand. The evidence suggests that multimodal care for the management of lateral epicondylitis may include education, exercise (strengthening, stretching, occupational exercise), manual therapy (manipulation) and soft tissue therapy (massage). The evidence does not support the use of multimodal care for the management of carpal tunnel syndrome.

CONCLUSIONS

The current evidence on the effectiveness of multimodal care for musculoskeletal disorders of the elbow, forearm, wrist and hand is limited. The available evidence suggests that there may be a role for multimodal care in the management of patients with persistent lateral epicondylitis. Future research is needed to examine the effectiveness of multimodal care and guide clinical practice.

[Finger bone and joint trauma of the hand in children]

The hand is the most commonly injured location of a child. Fractures of the digits are the most frequent lesions with two specific locations: 1) in the young child, the fracture is usually a crush injury, such as occurs when a hand gets caught in a door, with lesion of the distal phalanx; soft tissue associated injuries are the main problem in this location; 2) in the older child, the fracture is usually secondary to recreational sports, with lesion on the proximal phalanx of the second and fifth digits. Dislocations or sprains are less common. Most interphalangeal joint injuries occur at the proximal interphalangeal joint and are secondary to hyperextension with as results a volar plate injury. Most fingers injuries in children are treated non operatively with a favorable outcome. The treating physician should however identify those clinical situations that require surgery, as complications are most commonly due to a failure to identify and treat an injury requiring an operation acutely. These injuries include intra-articular fractures, displaced phalangeal neck fractures, and malrotated fractures. Malrotation or intra-articular malunion have no remodeling capacity. Non-union and stiff digits are uncommon but a significant trauma or a high-energy mechanism with severe soft tissues injuries appears to be a factor of risk.

Surgical exploration of hand wounds in the emergency room: Preliminary study of 80 personal injury claims

BACKGROUND

The SHAM Insurance Company in Lyon, France, estimated that inadequate hand wound exploration in the emergency room (ER) accounted for 10% of all ER-related personal injury claims in 2013. The objective of this study was to conduct a critical analysis of 80 claims that were related to hand wound management in the ER and led to compensation by SHAM.

MATERIAL AND METHODS

Eighty claims filed between 2007 and 2010 were anonymised then included into the study. To be eligible, claims had to be filed with SHAM, related to the ER management of a hand wound in an adult, and closed at the time of the study. Claims related to surgery were excluded. For each claim, we recorded 104 items (e.g., epidemiology, treatments offered, and impact on social and occupational activities) and analysed.

RESULTS

Of the 70 patients, 60% were manual workers. The advice of a surgeon was sought in 16% of cases. The most common wound sites were the thumb (33%) and index finger (17%). Among the missed lesions, most involved tendons (74%) or nerves (29%). Many patients had more than one reason for filing a claim. The main reasons were inadequate wound exploration (97%), stiffness (49%), and dysaesthesia (41%). One third of patients were unable to return to their previous job. Mean sick-leave duration was 148 days and mean time from discharge to best outcome was 4.19%. Most claims (79%) were settled directly with the insurance company, 16% after involvement of a public mediator, and 12% in court. The mean compensatory damages award was 4595Euros.

CONCLUSION

Inadequate surgical exploration of hand wounds is common in the ER, carries a risk of lasting and sometimes severe residual impairment, and generates considerable societal costs.
