Management of plantar puncture wounds in children

A Comparison of Pathogens in Skin and Soft-Tissue Infections and Pedal Osteomyelitis in Puncture Wound Injuries Affecting the Foot

BACKGROUND

To compare pathogens involved in skin and soft-tissue infections (SSTIs) and pedal osteomyelitis (OM) in patients with and without diabetes with puncture wounds to the foot.

METHODS

We evaluated 113 consecutive patients between June 1, 2011, and March 31, 2019, with foot infection (SSTIs and OM) from a puncture injury sustained to the foot. Eighty-three patients had diabetes and 30 did not. We evaluated the bacterial pathogens in patients with SSTIs and pedal OM.

RESULTS

Polymicrobial infections were more common in patients with diabetes mellitus (83.1% versus 53.3%; P = .001). The most common pathogen for SSTIs and OM in patients with diabetes was Staphylococcus aureus (SSTIs, 50.7%; OM, 32.3%), whereas in patients without diabetes it was Pseudomonas (25%) for SSTIs. Anaerobes (9.4%) and fungal infection (3.1%) were uncommon. Pseudomonas aeruginosa was identified in only 5.8% of people with diabetes.

CONCLUSIONS

The most common bacterial pathogen in both SSTIs and pedal OM was S aureus in patients with diabetes. Pseudomonas species was the most common pathogen in people without diabetes with SSTIs.

Outcomes of Foot Infections Secondary to Puncture Injuries in Patients With and Without Diabetes

It is difficult to compare foot infections in patients with diabetes to those without diabetes because foot infections are uncommon in people without diabetes. The aim of this study is to compare clinical outcomes in people with and without diabetes admitted to the hospital for an infected puncture wound. We evaluated 114 consecutive patients from June 2011 to March 2019 with foot infection resulting from a puncture injury; 83 had diabetes and 31 did not have diabetes. We evaluated peripheral arterial disease (PAD), sensory neuropathy, the need for surgery and amputation, length of hospitalization, and presence of osteomyelitis. Patients with diabetes were 31 times more likely to have neuropathy (91.6% versus 25.8%, p < .001, confidence interval [CI] 10.2 to 95.3), 8 times more likely to have PAD (34.9% versus 6.5%, p = .002, CI 1.7 to 35), and 7 times more likely to have kidney disease (19.3% versus 3.2%, p < .05, CI 0.9 to 56.5). They also took longer before presenting to the hospital (mean 20.1 ± 36.3 versus 18.8 ± 34.8 days, p = .09, CI 13 to 26.5); however, this result was not statistically significant. Patients with diabetes were 9 times more likely to have osteomyelitis (37.3% versus 6.5%, p = .001, CI 1.9 to 38.8). In addition, they were more likely to require surgery (95% versus 77%, p < .001, CI 1.6 to 21.4), required more surgeries (2.7 ± 1.3 versus 1.3 ± 0.8, p < .00001, CI 2.1 to 2.5), were 14 times more likely to have amputations (48.2% versus 6.5%, p < .0001, CI 3.0 to 60.2), and had 2 times longer hospital stays (16.2 ± 10.6 versus 7.5 ± 9 days, p = .0001, CI 11.9 to 15.9. Infected puncture wounds in patients with diabetes often fair much worse with more detrimental outcomes than those in patients without diabetes.

Plantar and Pedal Puncture Wounds in Children: A Case Series Study From a Single Level I Trauma Center

OBJECTIVES

The purpose of this study was to describe our experience in treatment of pediatric patient presenting with pedal puncture wound to our level I trauma center and describe our results for the need for hospitalization and/or surgery for these patients.

METHODS

Children and adolescents 18 years and younger presenting with pedal puncture wounds from September 2009 to December of 2013 were retrospectively studied. Exclusion criteria included adult patients, wounds related to animal bites, lacerations associated with a motor vehicle collision or all-terrain vehicle accidents, gunshot wounds, degloving injuries, or injuries resulting in complex lacerations to the foot.

RESULTS

A total of 147 children presented to emergency department (ED) with a pedal puncture wound. Average age was 9.8 years. Prophylactic antibiotic therapy was administered in 107 cases (72.8%). Fifteen patients (10%) were treated with intravenous or intramuscular antibiotics in the ED or after hospital admission, 81 patients (55%) were treated with oral medications (prescribed for them to be taken after discharge), and 35 patients (24%) received topical antibiotic treatment. Of the 147 patients included in the study, 9 patients (6%) required the need for hospitalization. Two patients were admitted for parenteral antibiotic treatment only, and 7 patients required formal surgical debridement in the operating room in addition to parenteral antibiotic therapy.

CONCLUSIONS

The majority of pediatric patients with pedal puncture wounds were treated in the ED with only a small percentage of patients requiring admission for either parenteral antibiotic treatment or formal surgical debridement.

Puncture wounds of the foot

Puncture wounds often appear benign but can cause significant pedal morbidity. Podiatric physicians who treat such wounds should educate local emergency room, urgent care center, and primary care physicians as to the potential complications associated with puncture wounds. Timely referral, recognition of the potential complications, and appropriate treatment ensure that the wound does not advance beyond a puncture wound. If complications have developed, aggressive treatment is required to eradicate the infection and prevent pedal amputation.

Contracture of the third toe as a delayed presentation of a foreign body in the foot

Foreign body retention in the foot after a penetrating injury is an unusual occurrence with varied presentation. A degree of suspicion needs to be present in situations where there is an inexplicable swelling, sinus, abscess, or tenderness. The authors present a case with a contracture of the third toe that had been caused by plantar fascial fibrosis secondary to retention of a rubber foreign body in the foot. This case report highlights the fact that an ultrasound to rule out retention of the foreign body might be a judicious investigation if common causes of toe contracture are excluded. It may also have therapeutic implications.

A new management strategy for puncture wounds of the foot. A case report

This is a case report of persistent foot infection after a deep puncture wound caused by a bolt which went through a sandal and into the foot. An occult rubber foreign body was missed by X-ray and MRI. On the basis of persistence of infection the foot was explored. A small dorsal skin incision converted a deep track into a tunnel, through which irrigation and curettage were done. With the rinse came a piece of rubber. The patient made a complete recovery. By converting the tract into a tunnel instead of extensive dissection, management was improved considerably. This strategy has not hitherto been reported.

Nail puncture wound through a rubber-soled shoe: a retrospective study of 96 adult patients

Nail punctures through rubber-soled shoes expose the foot to the possibility of deep infection and foreign body retention. In this article, we describe characteristics of adult patients who sustained nail puncture wounds through a rubber-soled shoe and were treated at our institution from January 1, 2000, to January 8, 2008. Of the 96 patients, 36 (37.5%) were treated conservatively and 60 (62.5%) were treated surgically in the operating room. Of those treated surgically, 15 (25%) had a foreign body extracted during the operation. The operated group had a longer duration of time from injury to hospital admission than did the nonoperated group (5.0 +/- 6.8 days versus 2.7 +/- 3.8 days, P < .05). Treatment success was observed in 91 (94.8%) of the patients, and the median lag time before admission for the less successfully treated group was longer than that for the successfully treated group (10 days versus 2 days, P < .002); and, the less successfully treated group was more likely to receive antibiotics in the community before hospitalization (100.0% versus 47.2%, P < .06), and was more likely to be diabetic (40.0% versus 9.9%, P < .10). Fever, white blood cell count, and erythrocyte sedimentation rate were not significantly associated with treatment outcome. Success of the treatment did not depend on white blood cell count, erythrocyte sedimentation rate, or fever. Ultrasonography was useful in detecting the presence of a foreign body.

Rapidly developing gas gangrene due to a simple puncture wound

Gas gangrene, an infection caused by Clostridium perfringens, is a potentially fatal and physically disabling disease due to its sometimes incredibly rapid progression. An adolescent boy was referred to our university hospital with a history of nail puncture in the hand that occurred a few hours previously. The physical examination revealed a swollen and tender arm with crepitations up to the shoulder. Gas was coming out from the puncture wound with digital pressure on the forearm. The plain radiograph of the arm was typical of gas gangrene with the presence of gas under the skin and between muscular fibrils.Having received 1 dose of meropenem, the boy had surgery, in which his entire upper extremity had to be disarticulated from the shoulder. The maintenance antimicrobial therapy with intravenously administered penicillin G and clindamycin was continued for a duration of 10 days, at the end of which, the patient was discharged.The rapidly progressive character and the dramatic ending of this case made us wonder whether antimicrobial prophylaxis would play any role in the preventive management of puncture wounds.

Delayed manifestations of the "Nail-Slipper injury"

Penetrating injuries of the foot are a common presenting complaint in the emergency department. The residents of the underdeveloped world are especially prone to suffer such injuries as barefoot walking is still common. However, a relatively common injury that occurs in the shod feet is the "Nail-Slipper injury". A metal nail penetrates through the rubber sole of the footwear introducing the rubber piece into the soft tissue of the foot. As the nail is removed the piece remains behind often leading to delayed manifestations. This article describes the various delayed manifestations of this injury. A leading question for the antecedent injury of this kind should be asked from all patients with such presentations, especially in the urban setting.
