Acute management of exercise treadmill-associated injuries in children

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.

Pediatric Treadmill Friction Burns to the Hand: Outcomes of an Initial Nonoperative Approach

Treadmill burns that occur from friction mechanism are a common cause of hand burns in children. These burns are deeper and more likely to require surgical intervention compared to hand burns from other mechanisms. The purpose of this study was to identify the factors associated with healing time using an initial nonoperative approach. A retrospective chart review was performed examining children (<15 years) who were treated for treadmill burns to the hand between 2012 and 2019. Patient age, burn depth, total body surface area of the hand injury, and time to healing were recorded. Topical wound management strategies (silver sheet, silver cream, non-silver sheet, and non-silver cream) and associated treatment durations were determined. For patients with burns to bilateral hands, the features, treatment, and outcomes of each hand were assessed separately. Cox regression analysis was used to evaluate the association between time to healing and patient characteristics and treatment type. Seventy-seven patients with 86 hand burns (median age 3 years, range 1-11) had a median total body surface area per hand burn of 0.8% (range 0.1-1.5%). Full-thickness burns (n = 47, 54.7%) were associated with longer time to healing compared to partial-thickness burns (HR 0.28, CI 0.15-0.54, P < .001). Silver sheet treatment was also associated with more rapid time to healing compared to treatment with a silver cream (HR 2.64, CI 1.01-6.89, P = .047). Most pediatric treadmill burns can be managed successfully with a nonoperative approach. More research is needed to confirm the superiority of treatment with silver sheets compared to treatment with silver creams.

Emergency department-reported injuries associated with mechanical home exercise equipment in the USA

The goal of this study was to generate national estimates of injuries associated with mechanical home exercise equipment, and to describe these injuries across all ages. Emergency department (ED)-treated injuries associated with mechanical home exercise equipment were identified from 2007 to 2011 from the National Electronic Injury Surveillance System. Text narratives provided exercise equipment type (treadmill, elliptical, stationary bicycle, unspecified/other exercise machine). Approximately 70 302 (95% CI 59 086 to 81 519) mechanical exercise equipment-related injuries presented to US EDs nationally during 2007-2011, of which 66% were attributed to treadmills. Most injuries among children (≤4 years) were lacerations (34%) or soft tissue injuries (48%); among adults (≥25 years) injuries were often sprains/strains (30%). Injured older adults (≥65 years) had greater odds of being admitted, held for observation, or transferred to another hospital, compared with younger ages (OR: 2.58; 95% CI 1.45 to 4.60). Mechanical exercise equipment is a common cause of injury across ages. Injury awareness and prevention are important complements to active lifestyles.

The Michigan hand outcomes questionnaire after 15 years of field trial

BACKGROUND

The Michigan Hand Outcomes Questionnaire has been used to assess a variety of hand and upper extremity injuries and conditions for nearly 15 years. It has been included in several overviews of upper extremity outcomes measures, but it has not been systematically examined regarding its clinometric properties during field trials.

METHODS

The authors conducted a review of the Michigan Hand Outcomes Questionnaire in the English language literature from 1998 through March of 2012. Data from clinical studies were abstracted and compiled.

RESULTS

The Michigan Hand Outcomes Questionnaire has been used in 58 clinical studies, and its clinometric properties have been analyzed in an additional 18 publications. The Michigan Hand Outcomes Questionnaire compares favorably with other hand outcomes instruments in the areas of test-retest reliability, validity, and responsiveness. High internal consistency may indicate redundancy within the items in the Michigan Hand Outcomes Questionnaire. The strength of the Michigan Hand Outcomes Questionnaire is its multidimensional construct in measuring patient-rated outcomes in symptom, function, aesthetics, and satisfaction.

CONCLUSIONS

The Michigan Hand Outcomes Questionnaire has been applied across a variety of conditions affecting the hand and upper limb. Its psychometric properties have been tested through field trials in various clinical settings around the world.

Management of treadmill hand injuries using soft tissue distraction

Background:

In the modern day cities, home treadmill usage is increasing. Toddlers are prone to a special injury by the treadmill, during workout the toddler tries to get on the belt and the roller action pulls the fingers under the belt and get caught between the belt and a metal rod under the machine and the belt scrapes the fingers. If untreated some of these injuries will lead to flexion contracture. The usual treatment is release of contracture and skin grafting, however, graft discoloration and recurrence of contracture are the complications of this method and the patients usually seek treatment for the brown discoloration of the grafts at a later age.

Objectives:

In this study we assess the results of Z-plasty in combination with soft tissue distraction without skin grafting with long term usage of splint as an alternative treatment for these patients.

Materials and Methods:

In this retrograde descriptive cross-sectional study, we evaluated the patients presented with treadmill hand injuries between the years 2006 and 2011. Demographic data including age and sex in addition to other information including location of trauma, severity of trauma, time elapsed between the trauma and treatment, type of treatment including wound care and surgical method and treatment outcomes were assessed.

Results:

A total of 8 patients (3 girls and 5 boys) following finger treadmill injury were assessed. 15 fingers in 7 patients had volar injury. The middle finger was the most commonly injured finger. In all patients a minimum of 2 fingers were injured and in just 1 patient 3 fingers were injured. In long-term follow-up all the patients had acceptable volar skin and complete ROM of the fingers.

Conclusions:

Due to discoloration of the skin graft and recurrence of contracture following skin graft as the sole treatment for the injury, application of Z-plasty with soft tissue distraction and long term splints seems to be a proper alternative treatment for these patients.

Pediatric treadmill injuries: a public health issue

BACKGROUND

Treadmill injuries in children tend to be severe and are becoming increasingly common. We present an overview of this problem to promote public awareness, education, and to advocate a prevention strategy for this preventable injury.

METHODS

Medical records of all children with treadmill-related injuries during a 6-year period (January 2001-November 2006) from 2 tertiary pediatric hospitals were reviewed. Data on patient demographics, injury related data, types of surgical procedure, and outcome of treatment were collected.

RESULTS

Forty-four children with treadmill-related injuries were admitted in a 6-year period (2001-2006). Each year, the incidence increased with 17 (39%) cases occurring in 2006 so far. The median age of injury at the time of incident was 2.8 years (range, 8 months-12 years). There was a higher incidence in males (55%) compared with females (45%). Most of these injuries were to the hand (75%), full-thickness burns (59%), <1% of total burn surface area (TBSA) (73%), and occurred while the treadmill was in use by an adult (34%). Twenty-one (47%) children required skin grafting surgery.

CONCLUSION

Treadmill-related burn injuries in children are a serious public health issue and warrants considerable attention. Adult supervision is paramount, and prevention strategies should include child safety features in equipment designs.

Pediatric hand friction burns from treadmill contact

BACKGROUND

Treadmills have become relatively common in American homes. This machine can be dangerous for children because they can sustain friction burns to the hands when the moving treadmill is touched. With aggressive wound care and physical therapy, most of these burns will heal without surgery. However, some patients will require reconstructive surgery to release contractures. We report our experience with a series of patients who suffered friction burns to the hand from contact with a moving treadmill. The purpose of this study is to further understand the incidence and outcomes of this type of injury.

METHODS

A retrospective chart review of all patients referred between September 2002 and June 2005 to our hand surgery clinic for treadmill friction burns on the hand(s) was conducted. Pertinent data collected included sex, age, injury distribution, and surgeries performed. An analysis of data maintained by the Consumer Product Safety Commission was used to understand the incidence of exercise equipment-induced injuries.

RESULTS

Thirteen pediatric patients were evaluated for friction burns on the hand. Their total injuries included 24 fingers, 1 hand, and 1 forearm. Three patients (23%) required surgery for release of flexion contractures. All wounds of the remaining 10 patients healed, and with the implementation of hand therapy programs did not require subsequent surgery.

CONCLUSIONS

Treadmill friction burns to the hands of children can lead to limitations of the motion of the hand. Because this problem is completely preventable, parents and treadmill manufacturers are encouraged to be proactive in preventing these injuries. In addition, prompt initiation of wound care and hand therapy is integral to a favorable outcome.

Characteristics of pediatric traumatic amputations treated in hospital emergency departments: United States, 1990-2002

OBJECTIVE

To examine the characteristics of children with traumatic amputations and the products associated with these injuries.

METHODS

Data regarding amputation injuries to children younger than 18 years treated in US emergency departments from 1990 to 2002 were obtained from the National Electronic Injury Surveillance System. Data included demographics, product involved, and body region injured.

RESULTS

An estimated 111,600 children younger than 18 years with amputation injuries were treated in US emergency departments from 1990 to 2002. The average age was 6.18 years (median: 4 years; mode: 1 year old). Males experienced 65.5% of these injuries. Finger amputations accounted for 91.6% of all amputations, ranging from 95.2% among 0- to 2-year-olds to 87.9% among 13- to 17-year-olds. Complete amputations accounted for 70.2% of all amputations among 13- to 17-year-olds compared with 52.6% of amputations among 0- to 2-year-olds. Adolescents also had the highest proportion of amputations resulting in hospital admission (26.6% for 13- to 17-year-olds compared with 11.9% for 0- to 2-year-olds). Adolescents had the highest proportion of amputation injuries involving lawn mowers (14.1% for 13- to 17-year-olds compared with 1.4% for 0- to 2-year-olds) and the highest proportion of amputations involving tools (29.3% for 13- to 17-year-olds compared with 2.5% for 0- to 2-year-olds). The percentage of amputations involving doors peaked in the youngest age group and decreased as age increased (65.8% of all amputations for 0- to 2-year-olds compared with 14.1% for 13- to 17-year-olds).

CONCLUSIONS

To our knowledge, this is the first study to use a nationally representative sample to broadly investigate amputation injuries among children. The majority of traumatic amputation injuries occur to young children, to males, and to fingers and the majority involve doors. Adolescents experience a higher proportion of more serious amputation injuries. Effective interventions exist but are inadequately used to prevent many of these injuries, including door stops and modifications, bicycle-chain and spoke guards, wearing closed-toe footwear while bicycling, a no-mow-in-reverse default feature on ride-on lawnmowers with the override switch located behind the mower operator, and a SawStop system on power saws. Use of these technical countermeasures and changes in relevant product standards to promote their implementation and use could lead to a decrease in pediatric traumatic amputations.

Pediatric hand injury induced by treadmill

Korea has recently seen an increase in pediatric hand injuries associated with treadmills. This study was conducted to identify the frequency, patterns, treatment and outcome of these injuries, in the hope of developing preventive programs. A retrospective review of the medical records of 25 children, all with treadmill-induced friction hand injuries, was conducted at the Hallym Burn Centre, Hangang Sacred Heart Hospital, Seoul, Korea, during the period of January 2002 to March 2004. The injuries constituted 1.4% of the total number of pediatric burn injury admissions. Male toddlers were affected more than female. The mean age of the children was 3.9+/-3.2 (3, 1-15) years old. Most injuries occurred in spring. Treadmill friction inflicted deep second or third degree burns, small in area (1.6+/-1.0% of TBSA). All lesions involved the hands and forearms, with 60% on the right. Most patients (64%) underwent surgical management 13+/-5 days after the injury. The volar surface of the hand was more affected than the dorsal side (27 versus 8). Treatment was mainly with full thickness skin graft (60%) and long-term surgical outcomes were excellent. Such injuries may be prevented by educating the public about the potential risks of the treadmill, and by the development of additional safety designs. Changes in management protocols and treatment policies would improve the provision of appropriate care.

Home Treadmill Friction Injuries: A Five-Year Review

Treadmills are popular home fitness machines in American homes. Young children are at risk for friction injuries if they contact moving treadmills. The purpose of this study was to determine the impact of treatment of treadmill friction injuries in children. A review of 1,211 pediatric patients younger than 6 years treated at the Intermountain Burn Center between July 1997 and June 2002 was conducted. Forty-eight of these cases (4%) were treadmill friction injuries. The mean TBSA of these burns was 0.5%. The volar surface of the hand was the most common site of injury. Twenty-two (46%) of the 48 identified patients had full-thickness injuries that were treated surgically. Medical costs associated with treadmill friction injuries averaged US 2,385 dollars. The number of treadmill friction accidents resulting in friction injuries to children less than 6 years of age deserves serious attention and increased public awareness.
