Reliability, usability and applicability of the ICD-11 beta draft focusing on hand injuries and diseases: results from German field testing.

OBJECTIVE: To test the interrater reliability when using the codes of the 11th revision of the International Classification of Diseases (ICD)-11 beta draft as well as ICD-10 and to explore the usability of the ICD-11 beta draft and the applicability of ICD-11's Supplementary section for functioning assessment in hand injuries and diseases. DESIGN: We conducted a validation study of the ICD-11 beta draft complemented by a single-centre study to collect clinical routine data on functioning. SETTING: German hand surgery clinics. PARTICIPANTS: Twenty-three physicians coded real-life cases containing diagnostic information on hand injuries and diseases. Additionally, clinical information of 100 patients was coded by 6 physicians and a nurse using ICD-11's Supplementary section for functioning assessment. MAIN OUTCOME MEASURES: Physicians coded 210 cases using the ICD-11 beta draft and ICD-10. Krippendorff's alpha was calculated. Clinical routine data was coded using 38 functioning categories. RESULTS: Interrater reliability (Krippendorff's alpha) of 0.67 for ICD-11 coding and 0.71 for ICD-10 coding was obtained, indicating substantial agreement. However, physicians reported a high proportion of problems with ICD-11 coding and slightly fewer problems with ICD-10 coding. The collected data on functioning could be mapped to ICD-11's Supplementary section for functioning assessment. For some data, however, only unspecific codes were available. CONCLUSIONS: Interrater reliability of ICD-10 and ICD-11 was satisfactory. Training material for ICD-11 is needed to further improve reliability and usability. Future users of ICD-11 should be encouraged to use the Supplementary section for functioning assessment to shed light on the problems patients experience in everyday life.

Revisión del diagnóstico de mano catastrófica a lo largo de 15 años en un hospital terciario: ¿hacemos un uso adecuado del término? / Review of catastrophic hand diagnosis over 15 years in a tertiary hospital: do we make proper use of the term?

Objetivo: Describir las características de los pacientes diagnosticados de «mano catastrófica» por el Servicio de Cirugía Plástica en un hospital de tercer nivel en el periodo comprendido entre 2000 y 2015; analizar la evolución del uso del término «mano catastrófica», y realizar una revisión bibliográfica con el objetivo de proponer la definición más óptima de dicha expresión. Material y método: Realizamos un estudio descriptivo y retrospectivo de los pacientes diagnosticados de «mano catastrófica» que requirieron atención hospitalaria por el Servicio de Cirugía Plástica de un hospital terciario en el periodo comprendido entre 2000 y 2015. Efectuamos una revisión bibliográfica acerca del uso del término «mano catastrófica» y aplicamos a nuestros resultados las clasificaciones propuestas en las publicaciones consultadas. Resultados: El número de diagnósticos de «mano catastrófica» fue de 133. Objetivamos una tendencia descendente en el empleo del mencionado término con el transcurso de los años. Aplicando clasificaciones basadas en la imposibilidad de recuperación de una mano aceptable (presencia de 3 dedos largos y pulgar) mediante procedimientos reconstructivos, tan solo 9 de 133 pacientes podían ser considerados «manos catastróficas», constituyendo un 6,7% del total de casos. Discusión: El término «mano catastrófica» posee diferentes acepciones, generando ambigüedad. El uso de una clasificación basada en la posibilidad de obtener una mano aceptable disminuye su utilización y mejora el abordaje de dichas lesiones. Conclusión: Abogamos por limitar el uso de «mano catastrófica» a los casos que cumplan criterios de «mano mutilada» y «mano metacarpiana» para evitar su uso indiscriminado y optimizar su manejo terapéutico

Objective: To describe the characteristics of patients diagnosed with 'catastrophic hand' by the plastic surgery department in a tertiary hospital in the period between 2000-2015, analyse the evolution of the use of the term 'catastrophic hand' and conduct a review of the literature with a view to proposing the optimal definition for said expression. Material and method: We conducted a descriptive and retrospective study of patients diagnosed with 'catastrophic hand' who required hospital care by the plastic surgery department of a tertiary hospital in the period between 2000-2015. We conducted a literature review on the use of the term 'catastrophic hand' and we applied the classifications proposed in the publications consulted to our results. Results: The number of 'catastrophic hand' diagnoses was 133. We observed a downward trend in the use of the term over the years. Applying classifications based on the impossibility of recovery of an acceptable hand (presence of three long fingers and thumb) by reconstructive procedures, only 9 out of 133 patients could be considered to have 'catastrophic hands', constituting 6.7% of the total cases. Discussion: The term 'catastrophic hand' has different meanings, and this generates ambiguity. The use of a classification based on the possibility of obtaining an acceptable hand diminishes its use and improves the approach for such injuries. Conclusion: We advocate limiting the use of 'catastrophic hand' to cases that meet criteria of 'mutilated hand' and 'metacarpal hand' to avoid indiscriminate use of the term and optimise therapeutic management

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.

[The International Classification of Functioning, Disability and Health (ICF) : The implementation of the ICF Core Sets for Hand Conditions in clinical routine as an example of application]. / Die Internationale Klassifikation der Funktionsfähigkeit, Behinderung und Gesundheit (ICF) : Implementierung in der klinischen Routine am Beispiel der ICF Core Sets der Hand.

The International Classification of Functioning, Disability and Health (ICF) provides a standardized language of almost 1500 ICF categories for coding information about functioning and contextual factors. Short lists (ICF Core Sets) are helpful tools to support the implementation of the ICF in clinical routine. In this paper we report on the implementation of ICF Core Sets in clinical routine using the "ICF Core Sets for Hand Conditions" and the "Lighthouse Project Hand" as an example. Based on the ICF categories of the "Brief ICF Core Set for Hand Conditions", the ICF-based assessment tool (ICF HandA) was developed aiming to guide the assessment and treatment of patients with injuries and diseases located at the hand. The ICF HandA facilitates the standardized assessment of functioning - taking into consideration of a holistic view of the patients - along the continuum of care ranging from acute care to rehabilitation and return to work. Reference points for the assessment of the ICF HandA are determined in treatment guidelines for selected injuries and diseases of the hand along with recommendations for acute treatment and care, procedures and interventions of subsequent treatment and rehabilitation. The assessment of the ICF HandA according to the defined reference points can be done using electronic clinical assessment tools and allows for an automatic generation of a timely medical report of a patient's functioning. In the future, the ICF HandA can be used to inform the coding of functioning in ICD-11.

Lumbrical muscle tear: clinical presentation, imaging findings and outcome.

The incidence of lumbrical muscle tear is increasing due to the popularity of climbing sport. We reviewed data from 60 consecutive patients with a positive lumbrical stress test, including clinical examination, ultrasound and clinical outcomes in all patients, and magnetic resonance imaging in 12 patients. Fifty-seven patients were climbers. Lumbrical muscle tears were graded according to the severity of clinical and imaging findings as Grade I-III injuries. Eighteen patients had Grade I injuries (microtrauma), 32 had Grade II injuries (muscle fibre disruption) and 10 had Grade III injuries (musculotendinous disruption). The treatment consisted of adapted functional therapy. All patients completely recovered and were able to return to climbing. The healing period in Grade III injuries was significantly longer than in the patients with Grade I or II injuries ( p < 0.001). We recommend evaluation of specific clinical and imaging findings to grade the injuries and to determine suitable therapy. LEVEL OF EVIDENCE: IV.

Interposition Tendon Graft and Tension in the Repair of Closed Rupture of the Flexor Digitorum Profundus in Zone III or IV.

We report the results of interposition tendon grafts using the ipsilateral palmaris longus tendon in 12 patients with closed flexor digitorum profundus tendon ruptures in zone III or IV of 14 digits between June 2006 and October 2015. Before surgery, 2 patients were diagnosed with closed tendon ruptures that occurred after nonunion of hamate hook fractures. The other 10 patients were diagnosed with spontaneous tendon ruptures of unknown cause. In 2 of the 10 patients with spontaneous tendon rupture, the cause of the rupture was not found. In the other 8 patients, there was rough surface with deficient overlying soft tissue on the radial side of the hamate hook. In all cases, the ruptured flexor digitorum profundus was reconstructed by applying overtension on the tendon graft, causing greater flexion than for the other normal digits. Hamate hook excision was also performed on 10 subjects with abnormalities. Postoperatively, the patients were followed for an average of 22.5 months (range, 12-64 months). At the final follow-up, the mean Disabilities of the Arm, Shoulder, and Hand questionnaire score was 5.7 (range, 3.3-8.3). There were excellent results in all 14 digits according to Strickland and Glogovac criteria. The mean total active motion was 167 degrees (range, 160-180 degrees). There were no surgical complications, including infection, adhesions, or tendon rerupture. There were excellent clinical results with the interposition tendon graft using palmaris longus for closed tendon rupture in zone III or IV of the hand. Applying overtension to the grafted tendon appears to be beneficial.

International Classification of Functioning, Disability and Health: development of an assessment set to evaluate functioning based on the Brief ICF Core Set for Hand Conditions - ICF HandA.

Timely identification of patients' problems after disorder or injury of the hand requires a thorough functional assessment. However, the variety of outcome measures available makes it difficult to choose the appropriate instrument. The brief International Classification of Functioning, Disability and Health (Brief ICF Core Set for Hand Conditions) provides a standard for what aspects need to be measured in hand injuries and disorders without specifying how to make the assessment. We developed the ICF-based Assessment Hand (ICF HandA), an assessment set for functioning based on the Brief ICF Core Set for Hand Conditions. First, we performed a literature review and an expert survey to pool outcome measures appropriate to assess functioning in clinical practice. At an interdisciplinary consensus conference experts decided on the outcome measures to be included in the ICF HandA. The ICF HandA provides a consensus on outcome measures and instruments to systematically assess function in patients with hand injuries and disorders.

A Novel Classification System for Injuries After Electronic Cigarette Explosions.

Electronic cigarettes (e-cigarettes) contain lithium batteries that have been known to explode and/or cause fires that have resulted in burn injury. The purpose of this article is to present a case study, review injuries caused by e-cigarettes, and present a novel classification system from the newly emerging patterns of burns. A case study was presented and online media reports for e-cigarette burns were queried with search terms "e-cigarette burns" and "electronic cigarette burns." The reports and injury patterns were tabulated. Analysis was then performed to create a novel classification system based on the distinct injury patterns seen in the study. Two patients were seen at our regional burn center after e-cigarette burns. One had an injury to his thigh and penis that required operative intervention after ignition of this device in his pocket. The second had a facial burn and corneal abrasions when the device exploded while he was inhaling vapor. The Internet search and case studies resulted in 26 cases for evaluation. The burn patterns were divided in direct injury from the device igniting and indirect injury when the device caused a house or car fire. A numerical classification was created: direct injury: type 1 (hand injury) 7 cases, type 2 (face injury) 8 cases, type 3 (waist/groin injury) 11 cases, and type 5a (inhalation injury from using device) 2 cases; indirect injury: type 4 (house fire injury) 7 cases and type 5b (inhalation injury from fire started by the device) 4 cases. Multiple e-cigarette injuries are occurring in the United States and distinct patterns of burns are emerging. The classification system developed in this article will aid in further study and future regulation of these dangerous devices.

Metacarpal-Like and Metacarpal Hand.

The metacarpal-like and metacarpal hand injuries are devastating conditions that render the hand nonfunctional. Although the metacarpal hand is well-studied, the metacarpal-like hand is never addressed. The authors, using the same principles as in the classification and treatment of metacarpal hand, propose an easy to follow treatment algorithm for metacarpal-like hand injury to guide the reconstructive surgeon. For both injuries, microsurgical toe-to-hand transplantation can restore an acceptable level of function if done properly. Meticulous planning is essential for the toe-to-hand surgery to achieve its prime goal of stable tripod pinch with insignificant morbidity at the donor sites.

Hand trauma: A prospective observational study reporting diagnostic concordance in emergency hand trauma which supports centralised service improvements.

BACKGROUND: Hand injuries are common, contributing up to 30% of accident and emergency (A&E) attendances. The aim of this study was to prospectively analyse the pathological demographics of hand injuries in a level 1 trauma centre with a Hand Trauma Unit and direct A&E links, and compare clinical and intra-operative findings. The null hypothesis was that there would be no differences between clinical and intra-operative findings (100% diagnostic concordance). METHODS: Data were prospectively collected for referrals during 2012. Referral diagnosis, additional pathologies found on clinical assessment and intra-operative findings were documented on a live database accessible from both the Hand Unit and associated operating theatres. Odds ratios were calculated using SAS. RESULTS: Injuries (1526) were identified in 1308 patients included in the study. Diagnostic concordance between Hand Unit clinical examination and intra-operative findings was 92.5% ± 2.85% (mean ± SEM); this was lower for flexor tendon injuries (56.3%) because a greater number of additional pathologies were found intra-operatively (2.25 ± 0.10). This 'trend' was noted across multiple referral pathologies including phalangeal fractures (1.28 ± 0.02; 82.9%), lacerations (1.33 ± 0.04; 79.1%), extensor tendon injuries (1.30 ± 0.05; 87.8%) and dislocations (1.18 ± 0.05; 87.8%). Odds ratio analysis indicated a relationship between primary referral diagnoses that were more or less likely to be associated with additional injuries (p < 0.05); referral diagnoses of flexor tendon injuries and lacerations were most likely to be associated with additional injuries. CONCLUSIONS: As hand injuries are a common presentation to A&E departments, greater emphasis should be placed on training clinicians in the management of hand trauma. Our findings, coupled with the presented relevant literature reports, lead us to advocate that A&E departments should move towards a system wherein links to specialist hand trauma services are in place; we hereby present useful data for hospitals implementing such services.

Open Fractures of the Hand: Review of Pathogenesis and Introduction of a New Classification System.

Open fractures of the hand are a common and varied group of injuries. Although at increased risk for infection, open fractures of the hand are more resistant to infection than other open fractures. Numerous unique factors in the hand may play a role in the altered risk of postinjury infection. Current systems for the classification of open fractures fail to address the unique qualities of the hand. This article proposes a novel classification system for open fractures of the hand, taking into account the factors unique to the hand that affect its risk for developing infection after an open fracture.

[Primary flexor tendons repair in zone 2]. / Réparation primitive des tendons fléchisseurs en zone 2.

Primary flexor tendon repair is still challenging even in the most experienced hands. With atraumatic surgery, the goal is to suture the tendon in a way that it will be strong enough to allow for tendon gliding without the risk of rupture or adhesions during the 12 weeks needed for the tendon to heal. After reviewing the zone 2 anatomy, the authors describe the state of art for flexor tendon repair along with their personal preferences. Although suture methods and postoperative rehabilitation programs are not universal, most specialized teams now use multistrand suturing techniques with at least 4 stands along with protected and controlled early active mobilization. Although the published rates of failure of the repair or postoperative adhesions with stiffness have decreased, these complications are still a concern. They will continue to pose a challenge for scientists performing research into the mechanics and biology of flexor tendon repairs, especially in zone 2.

Current guidelines for management of severe hand injuries.

BACKGROUND: Severe, multitissue hand injuries constitute a serious problem of the modern world. Despite investing significant funds in their management these injuries often exclude young people from professional life. It is often due to improper management conducted by untrained personnel lacking appropriate instruments. The goal of this work is to review the literature on the problem and attempt to organize this information. MATERIAL/METHODS: A review of available literature on mutilating hand trauma, amputations in the hand region, replantation and scales used for assessment of the severity of injury and hand function, both in Poland and internationally. RESULTS: Hand injuries may be managed through three approaches: concomitant definitive, delayed and secondary. The best results are achieved through the first approach. However sometimes, due to the character of injury or lack of trained personnel, the team is forced to apply temporary dressing and, subsequently, initiate complex further management. HISS scale is a useful tool allowing for precise determination of the severity of injury and, used together with DASH questionnaire, prediction of long-term treatment outcome. CONCLUSIONS: Necessary changes need to be implemented in the healthcare system in order to achieve better results of treatment of severe hand injuries. Proper guidelines for everyday practice should be also introduced. Changes should encompass precise determination of competences of individual centers as well as the mode and indications for patient transport between them. Training of doctors should be modified in such way to ensure that at least one person in each center would be capable of performing proper immediate management of such injuries, making further treatment possible. At the same time, financing, as a strong motivator, should promote appropriate management.

[Management of zone 1 flexor digitorum profundus tendon injuries]. / Prise en charge des lésions du tendon fléchisseur profond des doigts en zone 1.

Flexor tendons repair in zone 1 is classically considered providing good results with an overall satisfactory finger function. However, the objective functional results after surgical repair of flexor digitorum profundus are sometimes disappointing. The authors describe the different surgical repair techniques available to the operator from so-called "traditional" sutures to newer methods of internal fixation using miniaturized anchor sutures. The management of postoperative procedures, that of failures and old cases are reported.

Malunited fractures in the hand.

Posttraumatic deformity of a tubular bone in the hand after malunion can impact function due to alteration in mobility, strength, or associated pain. Surgical intervention is often indicated, with the surgical options based on both the type and location of the deformity, as well as any associated articular, tendon, or soft tissue constraints. This article provides a management approach based on the deformity classification, location, and any associated conditions.

Clinical use of a combined grasping and locking core suture technique for flexor tendon repair in zone II.

Previous authors have used either a grasping or a locking technique for flexor tendon repair in zone II. A combined (grasping and locking) 10-strand repair was used by the author in 22 adults (n = 28 fingers) with lacerations of both flexor tendons in zone II. The combined repair is known to be strong (mean tensile strength of 164 N), and the technique was used in selected cases who were thought to be at higher risk of rupture either because of excessive digital oedema (in early tendon repairs) or because of tendon retraction (in late primary tendon repairs). The 10-strand repair was bulky and, hence, only the profundus tendon was repaired; and "venting" of the pulley system was done proximal to the repair site as recommended by other authors. Supervised early active mobilisation was done immediately after the operation. At final follow-up, the outcome was calculated using the original Strickland-Glogovac grading system. There were no ruptures and the final outcome was considered excellent in 19 patients (n = 25 fingers), good in two patients (n = 2 fingers), and fair in the remaining patient (n = 1 finger). It was concluded that the bulky 10-strand repair may be used for zone II finger flexor tendon lacerations as long as a profundus-(?) only repair and "venting" of the pulley system are performed.
