Management of post burn hand deformities

Acute and Reconstructive Burn Care of the Hand

The hand is commonly affected in thermal injuries. Hand burns account for 39% of all burns and they are involved in 34% of instances when the total body surface area of a burn exceeds 15%. Inadequate or inappropriate treatment could result in significant morbidity. The ultimate integration of a burn patient into the society largely depends on the functionality of the hands. Hence, it is important to reduce complications by providing good care during the acute stage.

Evaluation of Functional Outcomes After Reconstruction of Post-burn Contracture of the Hand in the Pediatric Age Group: A Prospective Study

Background Injuries on the hand due to burns affect the quality and functions of activities of daily living (ADL). Severe burns cause lasting complications and deformities, such as contracture of the hand, which require multiple staged surgeries and rehabilitation for extended periods to regain function. This is of major significance to children, as they are in the growing and developmental age group, which should be considered while planning a reconstructive procedure. Psychological counselling is equally important for these patients to accept the residual deformity and cosmesis of the hand following surgery. Methods A prospective interventional study was conducted on 40 patients to assess the functional outcomes of various reconstructive procedures for post-burn contracture of the hand and to find out which is the better surgical intervention for restoring the hand functions needed for ADL. Functional outcomes were analyzed using the Modified Jebson Hand Function Test (JHFT) after a minimum of four months.  Results In the group of children operated on with flap procedures, the maximum number of patients had average functional outcomes. Functional outcomes were assessed using the Modified JHFT, in which fine motor, weighted, and non-weighted hand function activities were assessed and analyzed. However, in the group of children operated on by the Z-plasty procedure and skin graft procedure, the maximum number of patients had poor functional outcomes.  Conclusion The management of burn injuries on the hand and subsequent contractures is often challenging, especially in pediatric patients. Timely intervention, patient education, and surgical skills with an appropriate choice of reconstructive procedures play a vital role in achieving good postoperative results. This study showed that hands reconstructed using flap procedures had good functional outcomes compared to graft and Z-plasty procedures.

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.

The use of modified glove-like abdominal flap for reconstruction of contracture following burns of dorsal hand and fingers: A case report

Introduction and importance

Burn contracture has been a challenge for its acquired functional disabilities and deformities. Surgical reconstruction poses a significant challenge for optimal aesthetic and functional improvement. Super thin abdominal skin pedicle flap can be used, but it has only one pedicle from one site of abdomen and needs tissue expander for a larger defect. The use of modified glove-like abdominal flap has been stated to be an option mainly for the use on acute hand burn. In this study, application of the modified glove-like abdominal flap was applied to contracture of dorsal hand and fingers.

Case presentation

A 39-year-old male patient with severe contracted hand, eight-month post-burn injury presented at outpatient clinic Santosa Central Hospital in 2017. Multiple series of surgeries were performed on this patient, consisting of released contracture, defect closure using a modified “glove-like” thin abdominal flap, and flap separation.

Clinical discussion

Abdominal flap has been the commonly used technique but has the disadvantage of being bulky. Glove-like abdominal flap, a subcutaneous layer plane flap, can be performed simply, safely, and briefly. It has been published mainly for reconstruction for acute burn hand injuries, not for burn hand contracture.

Conclusion

The use of modified glove abdominal flap technique for reconstruction in hand burn contracture gives a satisfactory result in terms of functional and aesthetic outcome and can be an option in reconstruction in contracted dorsal hand and fingers.

•

Abdominal flap has been used to be an option for hand burn reconstruction but has the disadvantage of being bulky.

•

Glove-like abdominal flap has been published mainly for reconstruction for acute burn hand injuries, not burn hand contracture.

•

Glove-like abdominal flap is an easy technique, safely, briefly, not bulky, and give better functional aesthetic results.

•

Modified glove abdominal flap technique can be an option in reconstruction in contracted dorsal hand and fingers.

Early wound repair versus later scar repair in children with treadmill hand friction burns

The incidence of pediatric treadmill hand friction burns has been increasing every year. The injuries are deeper than thermal hand burns, the optimal treatment remains unclear. This was a retrospective study of children who received surgery for treadmill hand friction burns from January 1, 2015, to December 31, 2019, in a single burn center. A total of 22 children were surveyed. The patients were naturally divided into two groups: the wound repair group (13 patients), which was admitted early to the hospital after injury and received debridement and vacuum sealing drainage initially, and a full-thickness skin graft later; and the scar repair group (9 patients), in which a scar contracture developed as a result of wound healing and received scar release and skin grafting later. The Modified Michigan Hand Questionnaire score in the wound repair group was 116.31 ± 10.55, and the corresponding score in the scar repair group was 117.56 ± 8.85 (P>0.05), no statistically significant difference. The Vancouver Scar Scale score in the wound repair group was 4.15 ± 1.21, and the corresponding score in the scar repair group was 7.22 ± 1.09 (P<0.05). Parents were satisfied with the postoperative appearance and function of the hand. None in the two groups required secondary surgery. If the burns are deep second degree, third degree, or infected, early debridement, vacuum sealing drainage initially, and a full-thickness skin graft can obviously relieve pediatric pain, shorten the course of the disease, and restore the function of the hand as soon as possible.

Surgical Management of Post Burn Hand Deformities

Objective

To evaluate the efficacy of different surgical procedures on post burn contracture of hand.

Methods

A quasi-experimental study design was conducted at the Department of Plastics and Reconstructive Surgery, Dow University of Health Science, DR. Ruth KM Pfau, Civil Hospital, Karachi, Pakistan from 1^st June 2019 to 30^th November 2019. Ninety-three participants of burned hand contracture of either gender, aged between 6- 60 years were included in the study. Resurfacing surgery with skin graft and loco-regional flaps were done according to type of contracture with individualization for each patient. All patients were kept under follow up for ninety days to assess efficacy of contracture release for each surgical procedure was noted. SPSS version 23 was used to analyse data.

Results

Full thickness skin graft (FTSG) was performed in 60.2% cases, 17.2% with split thickness skin graft (STSG) and 12.9% with cross finger flaps. About 25% of recurrence was observed in cross finger flaps, whereas no recurrence was seen in Z-plasties and posterior interosseous flap. The significant association was between recurrence and surgical procedures (p<0.05).

Conclusion

Z-plasty followed by FTSG was effective in the management of post burn contractures of hand.

Dynamic Hand Pain from Generalized Skin Tightness Treated with First Webspace Release and Resurfacing

Contractures from burns or other trauma generally manifest as discrete areas of skin deficiency or localized scar bands in the hand, and are treated successfully with release and resurfacing of the affected area. We report a case of generalized bilateral skin tightness in the hand from severe childhood burns, with no obvious localized area of contracture, manifesting with pain and numbness when making a fist and with certain activities. This was treated with release and resurfacing of the first webspace with bilateral free lateral arm flaps as well as endoscopic carpal tunnel release, resulting in increased laxity of skin throughout both hands, and resolution of dynamic symptoms with activity.

Management of Hand Burn With Pedicled Converted Anterolateral Thigh Free Flap

The upper limb is involved in burns in a high percentage of cases and its reconstruction is extremely important, given the functional impact of this anatomical region. Among the reconstruction choices for severe and large structural defects, the pedicled anterolateral thigh flap is an available option. This case study discusses the utilization of the pedicled anterolateral thigh flap for reconstruction of a complex full-thickness hand burn, when adequate arterial perforators were not available. Complex hand burns can often present challenges for reconstructive coverage, because of the complex anatomy of the upper extremity and the need to preserve as much function as possible. The use the anterolateral thigh free flap is one option that can be utilized for coverage of these large hand defects, in the face of poor local tissue advancement options. The finding of inadequate or lack of perforator vessels necessitates intraoperative changes in the surgical approach. In these cases, different alternatives exist depending on the dimensions and characteristics of the required coverage, the dissection of a pedicled flap being one of them. The pedicled anterolateral thigh flap represents an alternative for the coverage of large hand defects in the absence of valid perforators during free-flap dissection.

Dorsal pentagonal island flap to reconstruct post-burn interdigital web

INTRODUCTION

This study reports the use of a dorsal pentagonal island flap for post-burn webbing contracture, in which the islanded flap is harvested from the burn scar tissue.

METHODS

Fourteen dorsal pentagonal island flaps were harvested in seven patients with post-burn webbing. Each flap was selected by examining the scar tissue donor using a modified Vancouver scar scale. Modification from the basic design was made according to the density of the donor scar tissue and the metacarpophalangeal joint movement.

RESULTS

All the flaps survived with normal abduction of the affected fingers. Modification of the flap design needed adjustment by assessing it through flexion and extension of the metacarpophalangeal joints. There was no incidence of web creep after two months to one year of follow-up.

CONCLUSION

Dorsal pentagonal island flap shows promising results as an alternative for reconstructing post-burn webbing.

Evaluation of Patients' Satisfaction and Functional Outcome of Dorsal Hand Unit Reconstruction in Burn Patients in Shiraz, Southern Iran

The aim of this study was to assess patients' satisfaction and functional outcome of dorsal hand unit reconstruction in burn patients in Shiraz, southern Iran.From September 2013 to February 2017, 11 patients (15 hands) with hand aesthetic complaint who were unhappy with their hand appearance were included for dorsal hand unit reconstruction. Under general anesthesia and tourniquet control, the burned tissue on dorsal surface of the hands was excised and a thick partial thickness skin graft was used for coverage, whereas the fingers were fixed by sutures to the palm. After 1 year, the five-points scale was used for evaluation of patients' satisfaction regarding the five major activities considered for hand function before and after operation. The mean age of the patients was 25.8 ± 5.17 years. The skin grafts were well taken. Six (40%) and eight patients (53%) reported the result of operation as completely satisfied and satisfied, respectively. Dorsal hand unit reconstruction in patients with dorsal hand contracture and significant dorsal scar was shown to simultaneously improve the function and aesthetic outcome of the surgery.

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.

A new option for definitive burn wound closure - pair matching type of retrospective case-control study of hand burns in the hospitalised patients group in the Dr Stanislaw Sakiel Centre for Burn Treatment between 2009 and 2015

Nearly 80% of all burns include the hands of affected individuals. Skin grafting is the gold standard in burns treatment, but in the case of the burn wound bed, it may require the necessity of utilising skin substitutes to facilitate closure. The aim of this study is to assess the impact of a porcine-derived wound dressing (Oasis™) for application to hand burns compared to a synthetic dressing (Suprathel™). Comparative assessments were made, including the time to heal, quality of healing and pain intensity. A retrospective, unblinded, matching pair case-control of hand burns was performed. A control group of 24 patients was treated with Suprathel dressing, and a study group of six patients underwent application of the Oasis dressing. The wound healing process was evaluated by taking histopathological specimens and also utilising the Bates-Jensen Wound Assessment Tool. A 10-cm Visual Analogue Scale (VAS) was used for pain assessment. Other parameters measured included dressing loss because of infection and the need of rehabilitation. The progress of wound healing on the fourth day in the study group was 30%. A decrease in the level of pain was recorded on the fourth day after surgery. There was a decrease of 5% in the risk of rehabilitation in the treatment group.

Functional and subjective assessment of burn contracture release in a mission setting

OBJECTIVE

Burns and subsequent contractures are common in developing nations. Contracture release is performed to treat such patients with functional limitations. The aim of this study is to evaluate post-operative functional and psychosocial outcomes following contracture release in a mission setting.

METHODS

During a surgical mission in Mumbai, India, 39 patients burn contractures underwent surgical release. A total of 31 patients (64% female, mean age 27 years) chose to participate in the study. Patients were scored preoperatively and postoperatively using a SF-36 validated survey and AMA impairment guideline assessment.

RESULTS

Thirty-one patients completed questionnaires pre-operative and 6-weeks post operatively. Twenty-four patients completed a survey 3-months post operatively (77.4%). Among those enrolled, 67% were women with the majority sustaining <20% total body surface area burns (70.7%) but had multiple contractures (80.6%). SF-36 physical component score increased from a mean score of 49.8 preoperatively to 55.6 by 3 months following contracture release (P<0.001). The SF-36 mental component score similarly increased from 38.8 to 51.1 by 3 months (P<0.001). AMA Whole Person Impairment (WPI) scores improved from 40.3% impairment pre-operative to 26.6% at 6-weeks post-operative (P<0.001).

CONCLUSIONS

Patients SF-36 and WPI scores improved following burn contracture release, confirming both functional and psychologic improvement following surgery. During the acute post-operative period, this study suggests that contracture release in a mission setting is of benefit to patients.

Study on Surgical Management of Post Burn Hand Deformities

CONTEXT

Functionality of the hands is the major determinants of the quality of life in burns survivors. If contractures or scarring affect the dominant hand, as they do on most occasions, the vocation and there by the economic status of the patient suffer.

AIM

The aim of this study is to evaluate the different surgical procedures for resurfacing after release of post-burn hand contractures in terms of functional recovery and aesthetic outcome.

SETTINGS AND DESIGN

It's a prospective, non-randomised study of 50 patients admitted and undergoing surgical reconstructive procedures for post burn hand contractures in our plastic surgery department.

MATERIALS AND METHODS

Resurfacing procedures were done according to type of contracture with individualisation for each case. All cases were followed up with physiotherapy and splinting advices. Functional and aesthetic outcome and recurrence of contracture for each procedure was noted at 6 months.

RESULTS

Forty seven percent of the cases were reconstructed with skin grafting, 30% cases with Z plasties and 23% with flap coverage. Split thickness skin grafts (STSG) and full thickness graft (FTSG) reconstructed cases had good recovery of joint mobility in 43% and 75% of cases respectively. Reconstructive procedures were aesthetically acceptable to the patients in 63%, 75% and 94% of STSG, FTSG and Z plasty cases respectively. Recurrence was seen in 17% of STSG done cases.

CONCLUSION

Most of the cases can be resurfaced with skin grafting and few cases have clear indication for flap coverage which needs to be planned and executed cautiously. Z plasties with proper planning gives maximum length gain with no donor morbidity as other procedures. Postoperative physiotherapy and splinting is must for better outcome in all cases.

Neglected post burns contracture of hand in children: Analysis of contributory socio-cultural factors and the impact of neglect on outcome

BACKGROUND

No study has ever evaluated the causes and effect of neglect on the outcome of post burns contractures of hand in children.

METHODS

66 hands in 61 children (mean age 12.22 years) with a mean neglect of 11.6 years (range 5-17 years) were assessed for the causes of neglect and the outcome of surgery. Average follow up was 6.6 years. The results were assessed in two groups of 5-10 years neglect as group I and >10 years neglect as group II.

RESULTS

In a total number of 134 contracted rays in 66 hands, the surgical procedures included local Z/V-Y flap (51 rays), cross finger flap (48 rays), full thickness graft (35 rays). Additional external fixator with a distracter was used in 3 patients treated at a delay of 14, 16 and 17 years. 50 (81.96%) patients belonged to rural and slum areas. The reasons for delayed treatment included poverty - 33 patients, lack of awareness of surgical treatment - 16 patients; and indifference of parents - 12 patients. 44 (72.13%) children were illiterates. With treatment the average DASH score improved from 65.10 to 36.90 (p < .000) and from 68.14 to 45.93 (p < .000) in group I and II respectively. The results were significantly superior in group I (p < .000).

CONCLUSION

The main factors for neglect in treatment of post burns contracture include poverty, lack of awareness and illiteracy. All the patients showed significant improvement in function after the surgery. Contractures with higher neglect had significantly inferior outcome.

Effect of educational program based on exercise therapy on burned hand function

BACKGROUND

Hands burn was associated with significant functional disorders that severely affected patient's quality of life. The aim of this study was to examine the effect of educational program based on exercise therapy on burned hand function.

METHODS

This experimental research was conducted in a period of ten months in 2010-2011 in Mottahari Hospital in Tehran in Iran. The sample included 60 patients, who were randomly assigned into experimental and control groups, half in intervention and half in control group. Educational program was implemented on experimental group. The data collection tools were two observational checklists about determining of hand function.

RESULTS

Both groups were matched in characteristic of demographic and burn injury. Subjects in experimental group demonstrated significant improvements in range of motion and hand function balance from admission to discharge.

CONCLUSION

In order to reduce the hand functional impairment caused by burns, it is recommended that special attention be paid to patient education about exercise therapy.

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.
