Contractures in burn injury part II: investigating joints of the hand. J Burn Care Res. 2008;29:606-613. [PMID: 18535473 DOI: 10.1097/bcr.0b013e31817db8e1]

Long-Term Functional Outcomes after Hand Burns: A Monocentric Controlled Cohort Study

Background: Hand burns are involved in 80-90% of severe burn injuries. Even though hands correspond to a small total burn surface area (TBSA) of less than 5%, the loss of their functionality has a significant impact on the patient's life. Studies that provide long-term results regarding hand functionality after hand burns are scarce. Therefore, this study aimed to investigate functional long-term results in a patient-centric approach regarding burn depth, unilateral and bilateral hand involvement, and (non-)isolated hand burns as potential influencing factors in patients with hand burns. Methods: We conducted a controlled cohort study of patients with burned hands treated at our department between 2005 and 2022. Healthy age-, sex-, and handedness-matched participants were used as controls. Data on the demographics, burn-related injuries, and treatments were collected. For a patient-centric approach, we used the Disabilities of the Arm, Shoulder, and Hand Questionnaire (Quick-DASH) and the Michigan Hand Questionnaire (MHQ) as patient-reported outcome measures for functional long-term evaluation, and the Patient and Observer Scar Assessment Scale (patient scale) for assessing long-term scar quality. Results: We enrolled 61 patients with 88 affected hands and 63 matched control participants. Up to 77.1% of the participants were male, with a mean age of 50.7 (±15.5) years and a follow-up of 8.1 (±4.7) years. The mean TBSA was 13.9% (±15.8), with 72.4% of the hands presenting with deep partial-thickness and full-thickness burns and most of the patients had only one hand affected (55.7%). The hand burn patients perceived significantly worse long-term functional scores in every domain of the MHQ as well as in the "overall function" and "work" of the Quick-DASH. Superficial hand burns negatively affected the two-handed activities of daily living (p = 0.013) and aesthetic appearance (p = 0.005) when both hands were involved. Isolated hand burns were associated with more difficulties in work performance (p = 0.03), whereas patients with bilateral hand involvement perceived more pain (p = 0.025). Conclusions: The patients with hand burns can achieve satisfactory long-term functional outcomes over time, but they do not reach the same long-term hand functionality as the healthy matched control group. Our study revealed that factors such as burn depth, unilateral or bilateral hand involvement, and (non-)isolated hand burns indeed have an impact on certain aspects of perceived long-term hand functionality.

Enzymatic Debridement (Nexobrid) on Burned Hands: Retrospective Review from a Burn Referral Center in Spain

Background

In deep burns, the gold standard of treatment is surgical debridement and coverage, but in hands, this may lead to poor aesthetic and functional results due to the complexity of this anatomical area. Enzymatic debridement (Nexobrid) allows for the preservation of the dermal remnant and reduces the number of skin grafts when compared with surgical excision. The study aimed to analyze the patients with intermediate second-degree or deeper burns in hands who required surgical treatment after Nexobrid and those who avoided it.

Methods

A descriptive retrospective study of all patients who underwent Nexobrid following hand burns between May 2015 and April 2020 treated in Vall d'Hebrón University Hospital was conducted. After the enzymatic debridement, the burn unit team determined if the burn required conservative treatment or surgery, based on the characteristics of the wound bed.

Results

A total of 202 hands were collected. Most hands included in this study had deep second-degree burns (122; 60.4%). Almost half of the hands underwent surgery (99; 49%), and most had deep second-degree burns (61; 61.62%). During follow-up, 24 hands required surgery for sequelae (11.88%) and 62 did not undergo follow-up (30.69%). In the group that needed sequelae surgery, 21 needed surgery after Nexobrid and three of them were healed with conservative treatment after Nexobrid (P < 0.001).

Conclusions

Nexobrid decreases the number of surgical procedures in deep burns of the hand because more conservative attitudes are adopted. Also, it seems to reduce the need of surgery due to burn sequelae.

Research and Development of a 3D-Printed Dynamic Finger Flexion Orthosis for Finger Extension Stiffness-A Preliminary Study

Finger extension stiffness is a common post-traumatic complication that results in the hand's functional impairment. In clinical practice, a dynamic splint enables the patient to stretch the affected finger independently. However, current dynamic splints have drawbacks, such as limited stretching efficacy, and interfere with the hand's functional activities. Therefore, this study aimed to develop a dynamic finger flexion orthosis capable of stretching each finger joint using additive manufacturing (AM) technology, thereby enabling hand functional activity, and analyze the clinical improvement in the range of motion (ROM). One subject with a hand fracture was recruited while undergoing a 7-week home-based rehabilitation program for the orthosis. The outcome measurements included the total active motion (TAM), the tip-to-finger distance (TPD), and the score on the Disability of Arm, Shoulder, and Hand (DASH) questionnaire. The results show that the TAM of the participant's fingers increased by 72.7 degrees on average, the TPD decreased by 3.5 cm on average, and the DASH score decreased to 9.5 points. The 7-week home-based rehabilitation program for the orthosis resulted in a 53.6% increase in the TAM on average. The developed orthosis improved hand function and enabled a more complete ROM in finger flexion.

Physical Medicine Applications in Hand Burns: Treatment or Rehabilitation

The aim of this study is to investigate the contribution of concurrent physical therapy to the preservation of hand function in patients with hand burns. This retrospective cohort study included the records of adult patients who presented with hand burns between July 1, 2020, and December 1, 2021. A total of 67 of 1578 burn patients who attended the clinic were included in this study. The patients' age, sex, total BSA with burns, causative agent, depth of burn on the hand, right or left hand, location of the burned area on the hand, treatment applied, healing time of the burn on the hand, limitation of movement, the joint restrictions, contractures, and compliance with physical therapy were assessed and recorded. Among the 67 patients included, 82.1% (n = 55) had no limitation in terms of their joint range of motion, whereas 17.9% (n = 12) had a limitation of movement in their finger joints. When the prevalence of movement limitation was examined by gender, such limitation was found to be more common in females (P = .041). Moreover, contractures were found to occur more frequently in patients with full-thickness burns (P = .032). It was also found that the limitation of movement was more severe in patients with skin grafts (P = .044). In addition, it was observed that the recovery time of the burn area was longer in those patients who had movement limitations (P = .004). In this study, we found that applying early physical therapy to patients after burn injuries facilitated the recovery of hand functions.

A Narrative Review of Outcomes in Burn Rehabilitation Based on the International Classification of Functioning, Disability, and Health

Burn injury commonly causes long-term physical impairments and psychosocial limitations that impact survivorship. This article uses the World Health Organization (WHO) International Classification of Functioning, Disability and Health (ICF) framework to summarize burn rehabilitation outcomes related to body functions and structures and how they relate to activities and participation within the social context. This article will contribute to a better understanding of burn recovery, facilitate the identification of specific and meaningful issues common to burn survivorship that may be under-reported in prior investigations and guide future rehabilitation to advance long-term burn outcomes.

Burn Injury Cutaneous Functional Units: Allocating Occupational Therapy Resources and Influencing Practice

Burn injury severity is currently determined by estimating the total body surface area (TBSA) burned, but this method fails to capture the severity of subsequent functional consequences. Alternatively, cutaneous functional units (CFUs)--skin segments that accommodate for movement and commonly become contracted--can be used to more accurately estimate burn severity based on functional consequences. Bilateral hands account for 81.3% of the body's CFUs, though only account for 5% of TBSA. However, hand burn survivors can have worse physical outcomes (ie, contractures, deformities) after burn injury, leading to subsequent loss of function, global occupational participation deficits, and poor psychosocial outcomes. This study, conducted at a verified American Burn Association burn center, explores how CFU involvement among adult burn survivors with uni and bilateral hand and upper extremity burns influenced occupational therapy practice in regards to time spent completing scar and soft tissue elongation techniques from the elbow to the digit tips per patient. The data showed, on average, burn occupational therapists require 0.8 minutes per CFU for an average total of 38.7 (SD = 29.5) minutes each session to complete scar and soft tissue elongation techniques to the upper extremities. The results of this study can be used to educate burn centers on the clinical utility of CFUs, burn occupational therapists regarding best-practice in terms of utilization of therapist time and resources, as well as support the justification for increasing occupational therapy services for patients with upper extremity and hand burns, and increasing staffing to meet patient need.

Critical Care Rehabilitation of the Burn Patient

Despite the fact that modern burn care has significantly reduced the mortality associated with severe burn injuries, the rehabilitation and community reintegration of survivors continues to be a challenge. An interprofessional team approach is essential for optimal outcomes. This includes early occupational and physical therapy, beginning in the intensive care unit (ICU). Burn-specific techniques (edema management, wound healing, and contracture prevention) are successfully integrated into the burn ICU. Research demonstrates that early intensive rehabilitation of critically ill burn patients is safe and effective. Further work on the physiologic, functional, and long-term impact of this care is needed.

Concepts in soft-tissue reconstruction of the contracted hand and upper extremity after burn injury

Burns and their subsequent contracture result in devastating functional and aesthetic consequences which disproportionally affect the upper extremity. By focusing on reconstruction with analogous tissue and utilizing the reconstructive elevator, function can be restored concomitantly with form and aesthetic appearance. General concepts for soft-tissue reconstruction after burn contracture are presented for different sub-units and joints.

Rehabilitation interventions after hand burn injury in adults: A systematic review

The aim of this review was to summarise the current evidence regarding the effectiveness of rehabilitation interventions in improving hand function, range of motion (ROM), hand strength, scar outcome, return to work, level of impairment/disability, level of burn knowledge and decreasing edema following hand burns in adult burn survivors. This review provides evidence-based support for the use of rehabilitation interventions for burn rehabilitation professionals. The following data sources were searched: MEDLINE, EMBASE and CINAHL from their inception up to February 2021, reference lists from all the included full-text articles were screened for additional relevant publications and monthly Google Scholar searches until December 23rd 2021 to make sure all new pertinent published articles after February 2021 would be included. Thirty-five studies were included in this review including 14 RCTs. Most of the included studies were Level 4 (46%; 16/35) and Level 2 (40%; 14/35) evidence. Only four studies were classified as Level 3 (14%; 5/35) evidence and none were considered Level 1. Most studies received a score of 5-9 (54%; 19/35) (Moderate quality). Fourteen studies received a score of ≥ 10 (40%; 14/35) (High quality) and only 2 studies received a score of< 5 (6%; 2/35) (Low quality). Articles were categorized according to the primary outcome targeted by the intervention. Clinical recommendations on higher-level evidence interventions are presented. This review supports the clinical practice of the following interventions: 1) The use of adhesive compression wraps for patients who have increased edema to increase hand function and ROM; 2) The use of compression (adhesive compressive wrap, compression bandage or intermittent compression pump) to decrease hand edema following burn injury; 3) Participating in general rehabilitation to increase hand function and patient perceived level of disability; 4) The use of an orthosis to increase ROM and a dynamic MCP orthosis to increase hand function; 5) If available, incorporate the use of VR based rehabilitation to increase hand function and hand strength; 6) The use of paraffin to increase hand PROM; 7) The use of gels to reduce hand scar thickness; 8) The use of an education component in rehabilitation to increase the level of burn knowledge. The limitations of this study are also discussed. Further research with robust methodology is needed to investigate the potential benefits of treatment interventions included in this review.

Safety of Early Postoperative Range of Motion in Burn Patients With Newly Placed Hand Autografts: A Pilot Study

Patients who suffer hand burns are at a high contracture risk, partly due to numerous cutaneous functional units, or contracture risk areas, located within the hand. Patients who undergo split-thickness skin grafting are often immobilized postoperatively for graft protection. Recent practice at our burn center includes an early range of motion (EROM) following hand grafting to limit unnecessary immobilization. The purpose of this study was to determine whether EROM is safe to perform after hand grafting and if there is any clinical benefit. This retrospective, matched case-control study of adults compared patients who received EROM to subjects who received the standard 3 to 5 days of postoperative immobilization. Patients were evaluated for graft loss and range of motion. Seventy-one patients were included in this study: 37 EROM patients and 34 matched controls. Six patients experienced minor graft loss, three of these were not attributable to EROM. All graft loss was less than 1 cm and none required additional surgery. Significantly more patients who received EROM achieved full-digital flexion by the first outpatient visit (25/27 = 92.6% vs 15/22 = 68.2%; P = .028). Performing EROM does not cause an increase in graft loss. All areas of graft loss from the EROM group healed without intervention. There appears to be a benefit to EROM since there was a significant improvement in the patients' ability to make a full fist at initial outpatient follow-up. Additional prospective analysis is needed to examine the true clinical utility of EROM in the hand and other contracture-prone areas.

Cross-cultural translation, adaptation and validation of the Burnt Hand Outcome Tool (BHOT) from English to French Canadian

BACKGROUND

The Burnt Hand Outcome Tool (BHOT) is a comprehensive tool assessing the multiple impacts of hand burn injuries which makes it essential to burn care practice, but is currently only available in English.

OBJECTIVES

To create a French-Canadian cross-cultural adaptation of the BHOT and to assess its content and construct convergent validity.

METHODS

The BHOT was translated and culturally adapted according to evidence-based principles for patient-reported outcome measures. The steps included translation to French (BHOT-F), backward translation, expert committee review, and cognitive debriefing with 5 adult participants. A pre-final version of the BHOT-F was then administered to 39 adult participants with hand burn injuries to assess construct convergent validity using the shortened Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH). Content validity was evaluated based on comments from the expert committee and participant burn survivors.

RESULTS

The BHOT-F was modified during the adaption process to ensure its clarity. The Cronbach's alpha value of 0.935 demonstrates the excellent internal consistency of the BHOT-F. The BHOT-F and the QuickDASH were strongly correlated (p < 0.01). Content validity was deemed satisfactory and recommendations are reported for future research.

CONCLUSIONS

The BHOT-F demonstrates adequate clinimetric properties to be used in clinical practice.

Five Essential Principles for First Web Space Reconstruction in the Burned Hand

BACKGROUND

Burn injuries commonly affect the hand, and the development of adduction contractures of the first web space is frequent and deleterious, both functionally and aesthetically. Many corrective techniques and algorithmic approaches have been described to treat this problem, but there is no consensus on the optimal management.

METHODS

A retrospective review at a single high-volume pediatric burn center was undertaken to evaluate the clinical course of these patients. All pediatric patients undergoing initial release of burn scar contracture of the first web space from 2005 through 2015 were included in a retrospective cohort study.

RESULTS

The authors identified 40 patients with 57 burned hands. The initial approach to management was variable. Z-plasty or other local flap was the first technique used in 28 hands (49 percent), split-thickness skin graft in 19 hands (33 percent), full-thickness skin graft in seven hands (12 percent), groin flaps in two hands (4 percent), and a reverse radial forearm flap in one hand (2 percent). The mean numbers of total reconstructive procedures per hand including the initial procedure were as follows: groin flap, 4.0; full-thickness skin graft, 3.1; split-thickness skin graft, 2.1; Z-plasty, 1.4; and reverse radial forearm flap, 1.0.

CONCLUSIONS

Successful reconstruction of the first web space must be addressed in the context of the entire hand. It is the authors' preference to use split-thickness skin grafting whenever a skin deficiency is present-only then should leading edge contractures be addressed with Z-plasty. Based on their experience, the authors recommend five principles that are essential to successfully treat postburn contractures of the first web space.

Long-term medical treatment of patients with severe burns at exposed sites

BACKGROUND

Body parts such as the face and hands are highly exposed during daily life and burns may accumulate in these areas. In addition, residual wounds, scar hyperplasia and contracture often exist in the late stage of a deep burn in these areas, which may affect patients’ appearance, movements, and mental health. However, inadequate attention has been paid to this issue which can result in problems, such as difficulty in healing, possibility of carcinoma, chronic pain and a heavy mental burden.

AIM

To investigate the long-term medical treatment of patients with severe burns at exposed sites following a mass burn casualty event.

METHODS

A retrospective analysis of 13 patients with severe burns at exposed sites was performed to determine their respective long-term medical treatment. A combined wound dressing scheme consisting of traditional Chinese and Western medicine was introduced to repair residual wounds. Active and passive functional exercises with massage, Chinese herbal baths and compression fixation were proposed to ameliorate the condition of the hands. A combination of physical, chemical and photoelectrical measures was adopted for anti-scar treatment. A psychological intervention and recovery guide was provided which corresponded to the patients’ psychological status.

RESULTS

Compared to patients who did not simultaneously receive the same treatment, patients who underwent systematic treatment recovered with a lower wound infection rate (P < 0.05), a shorter healing time (13.6 ± 3.2 d) compared with (19.1 ± 3.5 d) and more bearable pain during wound dressing at three days, one week and two weeks after a Chinese herbal bath (P < 0.05). Satisfactory results were achieved with regard to restored function of patients’ joints and blood supply to nerve endings, closure of the eyelids and the size of mouth opening tended to be normal, and only 7.1% of patients were diagnosed with severe scar hyperplasia and contracture deformity compared with 30.7% in the control group. In addition, the color, thickness, vascular distribution and softness score of the scars improved (P < 0.01), and the effects of the psychological intervention was remarkable as shown by the Self-Rating Anxiety Scale and Self-Rating Depression Scale.

CONCLUSION

A better prognosis can be achieved in patients in the late stage of a burn with active residual wound repair, limb functional exercise, anti-scar and psychological rehabilitation.

Effects of Virtual Reality-Based Rehabilitation on Burned Hands: A Prospective, Randomized, Single-Blind Study

Hands are the most frequent burn injury sites. Appropriate rehabilitation is essential to ensure good functional recovery. Virtual reality (VR)-based rehabilitation has proven to be beneficial for the functional recovery of the upper extremities. We investigated and compared VR-based rehabilitation with conventional rehabilitation (CON) in patients with burned hands. Fifty-seven patients were randomized into a VR or CON group. Each intervention was applied to the affected hand for four weeks, and clinical and functional variables were evaluated. Hand function was evaluated before intervention and four weeks after intervention using the Jebsen-Taylor hand function test (JTT), Grasp and Pinch Power Test, Purdue Pegboard test (PPT), and Michigan Hand Outcomes Questionnaire (MHQ). The JTT scores for picking up small objects and the MHQ scores for hand function, functional ADL, work, pain, aesthetics, and patient satisfaction were significantly higher in the VR group than in the CON group (p < 0.05). The results suggested that VR-based rehabilitation is likely to be as effective as conventional rehabilitation for recovering function in a burned hand. VR-based rehabilitation may be considered as a treatment option for patients with burned hands.

Joint flexibility problems and the impact of its operationalisation

BACKGROUND

Dissatisfaction is being voiced with the generally used way joint flexibility problems are defined (operationalised), i.e. as a range of motion (ROM) one or more degrees lower than normative ROM of healthy subjects. Other, specifically more function-related operationalisations have been proposed. The current study evaluated the effect of applying different operationalisations of joint flexibility problems on its prevalence.

METHOD

ROM data of 95 joints affected by burns of 23 children were used, and data on 18 functional activities (Burn Outcome Questionnaire (BOQ)). Five methods were used to operationalise joint flexibility problems: (1) ROM below normative ROM, (2) ROM below normative ROM minus 1SD, (3) ROM below normative ROM minus 2SD, (4) ROM below functional ROM, and (5) a score of 2 or more on the Likert Scale (BOQ).

RESULTS

Prevalence of joint flexibility problems on a group level ranged from 13 to 100% depending on the operationalisation used. Per joint and movement direction, prevalence ranged from 40% to 100% (Method 1) and 0% to 80% (Methods 2-4). 18% of the children received '2' on the Likert Scale (Method 5).

CONCLUSION

The operationalisation of joint flexibility problems substantially influences prevalence, both on group and joint level. Changing to a function-related operationalisation seems valuable; however, international consensus is required regarding its adoption.

TRIAL REGISTRATION

The study is registered in the National Academic Research and Collaborations Information System of the Netherlands (OND1348800).

Goniometric Measurement of Burn Scar Contracture: A Paradigm Shift Challenging the Standard

Standard goniometry is the most commonly used method of assessing the range of motion (ROM) in patients with burn scar contracture. However, standard goniometry was founded on arthrokinematic principles and doesn’t consider the cutaneous biomechanical influence between adjacent joint positions and skin pliability to accommodate motion. Therefore, the use of standard goniometry to measure burn scar contracture is called into question. This prospective, multicenter, comparative study investigated the difference between standard goniometry, based on arthrokinematics and a revised goniometry protocol, based on principles of cutaneokinematics and functional positions to measure ROM outcome in burn survivors. Data were collected for 174 joints from 66 subjects at seven burn centers totaling 1044 measurements for comparison. ROM findings using the revised protocol demonstrated significantly more limitation in motion 38.8 ± 15.2% than the standard protocol 32.1 ± 13.4% (p &lt; .0001). Individual analyses of the motions likewise showed significantly more limitation with revised goniometry compared with standard goniometry for 9/11 joint motions. Pearson’s correlation showed a significant positive correlation between the percentage of cutaneous functional units scarred and ROM outcome for the revised protocol (R2 = .05, p = .0008) and the Δ between the revised and standard protocols (R2 = .04, p = .0025) but no correlation was found with the standard goniometric protocol (R2 = .015, p = .065). The results of this study support the hypothesis that standard goniometry underestimates the ROM impairment for individuals whose motion is limited by burn scars. Having measurement methods that consider the unique characteristics of skin impairment and the impact on functional positions is an important priority for both clinical reporting and future research in burn rehabilitation.

Rehabilitation of Burn Injuries: An Update

A major burn is a severe injury with a global impact. Our system of medical evacuation has led to the survival of many severely injured service members. Burn rehabilitation is a complex and dynamic process and will not be linear. Recovery requires a comprehensive, interdisciplinary team-based approach, individually designed to maximize function, minimize disability, promote self-acceptance, and facilitate survivor and family reintegration into the community.

Quantifying Contracture Severity at Hospital Discharge in Adults: A Burn Model System National Database Study

Contracture is a common complication of burn injury and can cause significant barriers to functional recovery and rehabilitation. There are limited studies of quantitative range of motion after burn injury. The purpose of this study is to examine quantitative contracture outcomes by anatomical location, burn size, and length of stay in adults. Data were obtained from the Burn Model System National Database from 1994 to 2003. All adult patients with a joint contracture at acute discharge were included and 16 joint motions were examined. Contractures were reported as both mean absolute loss of normal range of motion in degrees and percent loss of normal range of motion. Analysis of variance was used to assess for a linear trend for contracture severity by burn size and length of stay. Data from 659 patients yielded 6,228 instances of contracture. Mean absolute loss of normal range of motion ranged from 20° to 65° representing an 18 to 45% loss of normal movement across the studied joint motions. In the majority of joint motions, contracture severity significantly increased with larger burn size and longer length of stay; however, wrist and many lower extremity joint movements did not demonstrate this trend. The data illustrate the quantitative assessment of range of motion deficits in adults with burn injury at discharge and the relation to burn size and length of stay.

Profile of Patients Without Burn Scar Contracture Development

Burn scar contractures (BSCs) are a frequently recognized problem for survivors of burn injury. In the burn literature, many reports focus on the frequency and factors associated with the BSC development. To the contrary, few burn rehabilitation publications report on patients who are able to successfully avoid developing BSC. From a prospective, multicenter study, data were extracted and reviewed on a group of 56 adult burn survivors who were discharged from their acute hospitalization without any measured BSCs. Forty-three variables with a recognized or presumed association with the development of BSCs were analyzed and are reported. Highlighted features of the noncontracted group included being an adult male with an educated background and few associated physical, medical, or social problems. The group had relatively small burn sizes that nonetheless required hospitalization. Despite the overall TBSA, the majority of the burn areas required skin grafting, although this area also represented a small area. The patient group had a longer than expected hospital stay. Rehabilitation was provided to patients on 80% of their hospital days. In addition, patients received sufficient rehabilitation treatment based on the number of cutaneous functional units involved in the burn injury. Patients were judged to have a high pain tolerance and compliant with rehabilitation. The results of this study document the clinical circumstances that patients with burn injury can be discharged from their acute hospitalization with the development of BSC. This study challenges the rehabilitation personnel to expand the upper limit of burn severity that can result in similar positive outcomes.

Reconstruction of the Adult and Pediatric Burned Hand

Thermal injuries of the hand can have a great impact on function. Initial treatment should focus on the prevention of contracture through the use of tissue-sparing techniques and optimized occupational therapy. Surgical intervention should follow the standard reconstructive ladder and can involve several techniques from simple to complex including minimally invasive techniques, such as laser and steroid injection, contracture release and skin grafting, and local tissue rearrangement and regional flaps as well as distant pedicled and free flaps. Reconstructive surgery of the hand, when performed well, can lead to meaningful functional improvement in severe burns.

Indications and Predictors for Reconstructive Surgery After Hand Burns

PURPOSE

The objective of this study was to analyze the prevalence, indications, and type of reconstructive surgery and predictors of the outcomes of reconstructive surgery after hand burns.

METHODS

A retrospective cohort study was conducted that included all patients admitted with acute hand burns in the Dutch burn centers from January 1998 through December 2002. The details of reconstruction including frequency, timing, indication, and techniques were collected over a 10-year follow-up period.

RESULTS

Hand burns were seen in 42% (n = 562 of 1,334) of all patients admitted with acute burns. Reconstructive surgery during the 10-year follow-up period was required in 15%. Contractures, especially of the first web space and little finger, were the most frequent indications for reconstructive surgery. Web spaces 1 to 3 and the little finger were the location most frequently operated on. The most frequently performed surgical technique was release of the contractures and the use of a random flap. Eighty percent of the reconstructive surgery patients required more than 1 reconstructive procedure, most often within 2 years of the initial injury. Secondary operations at the same location were required in 12%. In 40% of the patients, the first reconstructive surgery was performed within the first postburn year. Significant independent factors related to the need for reconstructive hand surgery were a larger area of full-thickness burns and surgical treatment of the hand during the acute phase.

CONCLUSIONS

Reconstructive surgery was required in 15% of patients who sustained hand burns. The majority of the patients requiring reconstructive surgery of the hand needed 2 or more operations to correct the contractures of the hand. Contractures of the little finger and first web space were the locations most frequently operated on. Patients with more extensive burns and who required hand surgery during the acute phase were more likely to need reconstructive surgery.

Outcomes Assessment After Hand Burns

Accurately assessing function and disability after hand burns is imperative to improving the management of patients. The biological, social, and psychological impact of these injuries should be considered. The International Classification of Functioning Disability (ICF) and Health Core Sets for Hand Conditions provides a guide to what should be measured and reported. Although many outcomes measures instruments are available to assess patients with hand or burn injuries, few are validated in the subpopulation of hand burns. Further efforts are required to investigate the ability of current assessment instruments to evaluate hand burn outcomes within the ICF framework.

Prevalence of scar contractures after burn: A systematic review

OBJECTIVE

Burn scar contractures are the pathological outcome of excessive scarring and ongoing scar contraction. Impairment of joint range of motion is a threat to performing activities in daily living. To direct treatment strategies to prevent and/or correct such contractures, insight into the prevalence, course, and determinants is essential.

METHODS

A literature search was conducted including Pubmed, Cochrane library, CINAHL, and PEDro. Articles were included if they provided burn scar contracture data to calculate the point prevalence. The quality of the articles was scored. Data were extracted regarding study, subject and burn characteristics, method of scar contracture assessment, point prevalence, and possible determinants.

RESULTS

Nine articles and one abstract could be included for data extraction. The prevalence at discharge was 38-54%, but with a longer time after burn, the prevalence was lower. Contractures were more likely to occur in more severe burns, flame burns, children, female, the cervical spine, and the upper extremity.

CONCLUSIONS

The prevalence of burn scar contractures varies considerably between studies. When prevalence is unclear, it is also difficult to investigate potential determinants and evaluate changes in interventions. There is a need for extensive, well-designed longitudinal (inter)national studies that investigate prevalence of scar contractures, their evolvement over time, and risk factors.

Clinical outcomes from a foam wedge splinting program for axillary contracture prevention in the intensive care unit

Preventing scar contracture after burn injury is a critical goal during recovery. Although the need for intervention is well-understood, data on specific techniques are limited. The study's objective is to provide data for the use of a foam abduction wedge in terms of safety, effectiveness, and patient and caregiver satisfaction through a prospective, single-arm trial. All patients presenting with a burn injury that required grafting in the axillary region and placed them at risk for shoulder joint contracture were offered inclusion. Patient outcomes were recorded for the duration of their burn intensive care unit admission. Ten subjects completed the protocol with a mean duration of wedge use of 41.5 ± 32.5 days. At discharge, the mean shoulder abduction was 132° ± 38° on the left and 118° ± 22° on the right. The mean shoulder flexion was 132° ± 31° on the left and 123° ± 29° on the right. As much as 90% of the subjects had greater than 90° of shoulder abduction and flexion at discharge. There were no observations of worsening burn injury wounds, graft failure, or new pressure-related wounds. One patient was found to have an upper-extremity peripheral nerve injury that was not clearly associated with the splint. Patient and nursing surveys indicated areas of satisfaction as well as areas for potential improvement. This study illustrates the anticipated clinical outcomes and care issues associated with the use of a specific contracture prevention method used in the burn intensive care unit setting as well as identifying areas for future research.

Hierarchical decomposition of burn body diagram based on cutaneous functional units and its utility

A burn body diagram (BBD) is a common feature used in the delivery of burn care for estimating the TBSA burn as well as calculating fluid resuscitation and nutritional requirements, wound healing, and rehabilitation intervention. However, little change has occurred for over seven decades in the configuration of the BBD. The purpose of this project was to develop a computerized model using hierarchical decomposition (HD) to more precisely determine the percentage burn within a BBD based on cutaneous functional units (CFUs). HD is a process by which a system is degraded into smaller parts that are more precise in their use. CFUs were previously identified fields of the skin involved in the range of motion. A standard Lund/Browder (LB) BBD template was used as the starting point to apply the CFU segments. LB body divisions were parceled down into smaller body area divisions through a HD process based on the CFU concept. A numerical pattern schema was used to label the various segments in a cephalo/caudal, anterior/posterior, medial/lateral manner. Hand/fingers were divided based on anatomical landmarks and known cutaneokinematic function. The face was considered using aesthetic units. Computer code was written to apply the numeric hierarchical schema to CFUs and applied within the context of the surface area graphic evaluation BBD program. Each segmented CFU was coded to express 100% of itself. The CFU/HD method refined the standard LB diagram from 13 body segments and 33 subdivisions into 182 isolated CFUs. Associated CFUs were reconstituted into 219 various surface area combinations totaling 401 possible surface segments. The CFU/HD schema of the body surface mapping is applicable to measuring and calculating percent wound healing in a more precise manner. It eliminates subjective assessment of the percentage wound healing and the need for additional devices such as planimetry. The development of CFU/HD body mapping schema has rendered a technologically advanced system to depict body burns. The process has led to a more precise estimation of the segmented body areas while preserving the overall TBSA information. Clinical application to date has demonstrated its worthwhile utility.

Corrective and reconstructive surgery in patients with postburn heterotopic ossification and bony ankylosis: an evidence-based approach

Articular heterotopic ossification (HO) and subsequent bony ankylosis (BA) are infrequent yet devastating complications of severe burn injuries. These conditions are diagnosed clinically and confirmed by imaging. Patients then begin active physical therapy until cleared for surgery, which remains the standard of care. This study critically reviews the existing literature on the diagnosis, treatment, and surgical outcomes of HO/BA in severely burned patients and provides an evidence-based treatment algorithm. A comprehensive search for all the studies addressing HO and BA after burn injury was conducted using PubMed and Google Scholar from 1957 to 2013. Fifty-one studies on postburn HO/BA have been published, reporting incidences from 0.1 to 35.3%. Most patients suffered from third-degree, thermal burns, with a mean TBSA of 49 ± 14%. The mean time from burn until diagnosis was 7 ± 11 months. Seventy-nine percent of the affected joints were elbows and 84% had adjacent and/or overlying burns. Ninety-one percent of joints had solely extra-articular HO. Ninety percent of HO/BA cases were treated with anatomic excision, and all achieved appreciable increases in range of motion with infrequent recurrence. Perioperative radiotherapy was used infrequently. Surgical articular reconstruction is the standard of care for postburn HO/BA severe enough to limit joint movement and/or function. Early detection and initiation of physical therapy are paramount in preventing progression to complete BA. Increased awareness and more rapid means of detecting postburn articular changes may permit earlier discontinuation of passive range of motion exercises, thereby halting the initiation and progression of HO.

Feasibility of an Exoskeleton-Based Interactive Video Game System for Upper Extremity Burn Contractures

BACKGROUND

Burn contractures are common and difficult to treat. Measuring continuous joint motion would inform the assessment of contracture interventions; however, it is not standard clinical practice. This study examines use of an interactive gaming system to measure continuous joint motion data.

OBJECTIVE

To assess the usability of an exoskeleton-based interactive gaming system in the rehabilitation of upper extremity burn contractures.

DESIGN

Feasibility study.

SETTING

Eight subjects with a history of burn injury and upper extremity contractures were recruited from the outpatient clinic of a regional inpatient rehabilitation facility.

METHODS

Subjects used an exoskeleton-based interactive gaming system to play 4 different video games. Continuous joint motion data were collected at the shoulder and elbow during game play.

MAIN OUTCOME MEASURES

Visual analog scale for engagement, difficulty and comfort. Angular range of motion by subject, joint, and game.

RESULTS

The study population had an age of 43 ± 16 (mean ± standard deviation) years and total body surface area burned range of 10%-90%. Subjects reported satisfactory levels of enjoyment, comfort, and difficulty. Continuous joint motion data demonstrated variable characteristics by subject, plane of motion, and game.

CONCLUSIONS

This study demonstrates the feasibility of use of an exoskeleton-based interactive gaming system in the burn population. Future studies are needed that examine the efficacy of tailoring interactive video games to the specific joint impairments of burn survivors.

Longitudinal burn scar quantification

Quantitative studies of the clinical recovery of burn scars are currently lacking. Previous reports validate the objective, precise, diagnostic capabilities of high-frequency ultrasound to measure thickness, the Cutometer(®) to measure pliability and the Mexameter(®) to measure erythema and pigmentation of scars. Thus, we prospectively quantified clinical characteristics of patient-matched, after burn hypertrophic scar (HSc), donor site scar (D) and normal skin (N) using these instruments. One investigator measured 3 sites (HSc, D, N) in 46 burn survivors at 3, 6, and 12 months after-burn. A mixed model regression analysis, adjusting p-values for multiplicity of testing, was used to compare means among sites and time points. Participants were 41.2±13.5 years old, 87% males, predominantly Caucasian, with an average of 19.5% body surface area burned. HSc thickness decreased significantly between 3 and 6, 6 and 12, and 3 and 12 months (all p<0.0001), but remained thicker than D and N skin (all p<0.0001). Pliability differed significantly between HSc, D and N sites at all time points (all p<0.0001), with HSc and D increasing between 3 and 12 months (p<0.05) but not reaching normal. HSc and D sites were significantly more erythematous than normal skin (p<0.05) at 3 and 6 months but D sites approached normal by 12 months. The only time points at which pigmentation significantly differed were the HSc and D sites at 6 months. Thickness, pliability, erythema and pigmentation of N skin remained similar over the 12 months. We found that post-burn HSc thickness, pliability and erythema differed significantly from D and N skin at 3, 6, and 12 months and does not return to normal by 12 months after-injury; however, significant improvements towards normal can be expected. Donor sites are redder than normal skin at 3 and 6 months but can be expected to return to normal by 12 months. Although the color of HSc and D sites change markedly with time these color changes are primarily due to changes in redness of the site, not melanin in this primarily Caucasian population.

Treating burn-associated joint contracture: results of an inpatient rehabilitation stretching protocol

The prevention and treatment of scar contracture is critical after significant burn injuries to avoid functional impairment. However, descriptions of specific contracture treatment interventions and outcomes are limited. Our objective is to provide detailed information and range of motion outcomes regarding the use of an intensive stretching protocol for burn-associated contracture. As part of a quality improvement measure, all patients admitted to inpatient rehabilitation with burn injury were treated with at least 1 hour of daily stretching by experienced therapists and were tracked with standardized range of motion measurements. Eighty-eight joint contractures were treated across nine patients for up to 4 weeks. The average weekly improvement in range of motion was 8.2 degrees (95% confidence interval [CI], 6.5-9.9). The largest gains were seen in the first week of treatment with an average improvement of 11.2 degrees (95% CI, 8.7-13.6). Eighteen digit contractures were treated across four patients. The average weekly improvement in flexion was 7.2 mm (95% CI, 5.2-9.1) again with larger gains in the first week of treatment-12.8 mm (95% CI, 10.3-15.4). Thumb opposition improved across five patients in the first week with an average improvement of 1.4 on the opposition scale (95% CI, 0.4-2.5). Intensive stretching by experienced therapists yielded significant improvements in joint range of motion for patients with burn-associated joint contracture. Defining specific burn contracture interventions remains a key goal in advancing burn rehabilitation in the future.

Rehabilitation of hand burn injuries: current updates

The improved short and long term survival rate of individuals with large burn injuries has made rehabilitation for optimal recovery of the patient increasingly important. Burn injury to the hands worsens the prospect of functional recovery and good quality of life in single events, especially when included in larger burns. The purpose of this paper is to present a narrative review of examination strategies used for children with burn injuries to the hands in the acute, intermediate and long term stages of rehabilitation, and apply these concepts to selected treatments, using a case that is representative of this complex patient population. The model of health described by the World Health Organisation provided the framework for the review, to structure the review in the domains of body structures and body functions, functional activities and participation in life roles. The lack of consensus in the burn literature regarding the most appropriate outcome measures and interventions necessitates futures research and long term outcome studies to identify, predict and prevent the difficulties patients may face over their lifespan.

Physical and quality of life outcomes of patients with isolated hand burns--a prospective audit

Hand burns can have major implications on function, appearance, and quality of life. Our clinical practice has changed over the last 10 years, with a steady increase in the proportion of hand burns receiving early and aggressive surgical management using Biobrane® sheets/gloves and a concomitant fall in the proportion requiring excision and split skin grafting. The aim of this study was to measure a comprehensive range of outcomes for patients admitted with isolated hand burns to review our outcomes and provide us with the "expected" patterns of recovery. A prospective audit was performed over a 14-month period, with outcomes measured during hospital admission and at 2 weeks, 1, 3, 6, and 12 months postinjury (depending on the method of management). Outcomes comprised pain, the Burns Specific Health Scale (abbreviated version B), return to work/leisure, total active range of motion, grip strength, the Michigan Hand Questionnaire, and scar appearance using Matching Assessment with Photographs of Scars. A total of 52 patients (35 male, mean age 39 years) with 57 burned hands participated. Patients whose burn injuries were such that they were able to be managed conservatively or with Biobrane® showed rapid recovery in all outcomes, with normal or near-normal values achieved within 2 weeks to 1 month postinjury. The patients whose burn injuries required excision and split skin grafting demonstrated more marked initial deterioration, a slower rate of improvement, but eventual good recovery. In conclusion, for this sample of patients with isolated hand burns, recovery was good and rapid for those whose burn injuries were such that they were managed conservatively or with Biobrane®.

Randomized controlled trial of daily total end range time (TERT) for Capener splinting of the stiff proximal interphalangeal joint

OBJECTIVE

Capener splinting is a common treatment for extension deficit of the proximal interphalangeal (PIP) joint. This study compared the effect of daily splint total end range time (TERT) of 6-12 hr versus 12-16 hr.

METHOD

Twenty-two participants with extension deficits of the PIP joint were randomly allocated to a daily TERT of 6-12 hr or 12-16 hr. Progress after 8 wk of splinting was evaluated.

RESULTS

No significant difference was found in change in extension range of motion (ROM) between groups (active ROM, F[4, 17] = 2.19, p = .13; passive ROM, F[4, 17] = 0.95, p = .46; torque ROM, F[4, 17] = 1.49, p = .26). Considerable crossover between groups resulted in a similar average daily TERT (9.5 hr for the 6-12 hr group vs. 11.5 hr for the 12-16 hr group).

CONCLUSION

Further research with a larger sample is needed to determine whether longer daily TERT is beneficial. Our results suggest, however, that most patients find it difficult to wear splints >12 hr/day.

Effects of modified dynamic metacarpophalangeal joint flexion orthoses after hand burn

OBJECTIVE

To assess the effectiveness of modified dynamic metacarpophalangeal joint flexion orthoses for treatment of post-burn hand contractures.

METHOD

We enrolled 42 hand burn patients with limited range of motion at the metacarpophalangeal joints in this study. The patients were randomly assigned into either a control or an orthotic group. Both groups received the standard rehabilitation therapy focused on hand therapy; 21 subjects in the orthotic group wore a splint for 3 hours per day for 8 weeks. Hand function was measured by active range of motion, grip strength and other assessment tools. All parameters were estimated using the Mann-Whitney U test at the beginning and the end of the treatment after 8 weeks.

RESULTS

The 21 subjects that had an orthotic intervention showed significant improvement in the range of motion at 2nd, 3rd, 4th and 5th metacarpophalangeal joints (p<0.05). However, the grip strength was not significantly increased after the 8 weeks of treatment compared to control group (p>0.05). There was a significant difference in the hand function scales between the 2 groups (p<0.05).

CONCLUSION

The modified dynamic metacarpophalangeal joint flexion orthoses provide continuous flexion to metacarpophalangeal joint that is needed for the restoration of range of motion in post-burn hand contractures. For the clinical application of hand orthoses in patients with hand disorders, additional research into its affects are required.

Dynamic splinting for the stiff hand after trauma: predictors of contracture resolution

STUDY DESIGN

Prospective cohort.

INTRODUCTION

Many variables are believed to influence the success of dynamic splinting, yet their relationship with contracture resolution is unclear.

PURPOSE OF THE STUDY

To identify the predictors of outcome with dynamic splinting of the stiff hand after trauma.

METHODS

Forty-six participants (56 joints) completed eight weeks of dynamic splinting, and the relationship between 13 clinical variables and outcome was explored.

RESULTS

Improvement in passive range of motion, active range of motion (AROM), and torque range of motion averaged 21.8°, 20.0°, and 13.0°, respectively (average daily total end range time, 7.96 hours). Significant predictors included joint stiffness (modified Weeks Test), time since injury, diagnosis, and deficit (flexion/extension). For every degree change in ROM on the modified Weeks Test, AROM improved 1.09° (standard error, 0.2). Test-retest reliability of the modified Weeks Test was high (intraclass correlation coefficient [2, 1]=0.78).

CONCLUSIONS

Better progress with dynamic splinting may be expected in joints with less pretreatment stiffness, shorter time since injury (<12 weeks), and in flexion rather than extension deficits. Further research is needed to determine the accuracy with which the modified Weeks Test may predict contracture resolution.

Alternate splint for flexion contracture in children with burns

Splinting children and ensuring that children wear the splint can be challenging tasks for both the therapist and the caregiver. Sometimes creativity is needed to create a pediatric splint that is easy to don and stays in place. These authors describe their challenge with pediatric burn patients either not wearing or losing their splint and how they now combine the splint directly into the pressure garment to ensure better patient compliance

Efficacy of inpatient burn rehabilitation: a prospective pilot study examining range of motion, hand function and balance

PURPOSE

To examine the effect of inpatient rehabilitation therapy on range of motion, hand function and balance in the burn population.

METHODS

This study utilizes a prospective longitudinal design. Inclusion criteria are adults admitted to a regional inpatient rehabilitation hospital with a primary diagnosis of burn injury. Demographic and medical data are collected. Primary outcomes include range of motion at four joints (shoulder, elbow, hip, knee), hand function (Jebsen Taylor Hand Test) and balance (Berg Balance Scale). Outcomes are measured at admission and discharge. Students't-test is used to determine significant differences in outcomes from admission to discharge.

RESULTS

Eleven subjects meet inclusion criteria. The mean age is 50 years, rehabilitation length of stay is 35 days and total body surface area burned is 41%. Subjects demonstrate significant improvements in range of motion, hand function and balance from admission to discharge (p<0.05).

CONCLUSIONS

Specific functional measures, range of motion, hand function and balance, demonstrate significant improvement during inpatient rehabilitation. Future work is needed to investigate other functional benefits of rehabilitation and to compare the impact of inpatient rehabilitation to other therapeutic interventions.

The modified Patient and Observer Scar Assessment Scale: a novel approach to defining pathologic and nonpathologic scarring

BACKGROUND

Scarring is a highly prevalent and multifactorial process, yet no studies to date have attempted to distinguish pathologic from nonpathologic scarring.

METHODS

This article defines and proposes methods of classifying pathologic scarring as it pertains to clinical presentation.

RESULTS

The authors propose a new scar scale that incorporates pain and functional impairment.

CONCLUSIONS

The modified Patient and Observer Scar Assessment Scale is the first of its kind to factor in the functional deficits pain and pruritus of scarring into measurements of associated morbidity. This scale has great potential in evaluating patient response to treatment and analyzing clinical outcomes.
