Orthopedic pitfalls in the ED: fight bite

Honey dressing for penile skin avulsion caused by traditional circumcision: a case report

OBJECTIVE

Penile skin avulsion is a rare complication of circumcision but commonly encountered as the result of traditional practice. We aimed to present the use of honey dressing and the benefit of its wound healing properties for management of such a complex wound.

CASE

A 24-year-old male patient with penile bleeding presented to the emergency department after undergoing traditional circumcision. Complete degloving of the penis with active bleeding and foul odour, along with heavy contamination of chewed betel leaves and powdered amoxicillin was found. Honey (Madu Nusantara, PT. Madu Nusantara, Indonesia) was used as dressing after copious irrigation using saline and povidone-iodine with bleeding control.

RESULTS

Honey dressing was shown to be effective for secondary wound healing of such a complicated and contaminated wound-in this case due to its antimicrobial, anti-inflammatory, immunostimulatory and autolytic debridement properties. A complete re-epithelialisation of the wound was achieved without progression to the hard-to-heal state by day 43. Suboptimal sexual function and aesthetic result due to wound contracture were observed as surgical reconstruction via split-thickness skin graft was refused due to cost.

CONCLUSION

In this case report, honey dressing was shown to be effective for wound healing, even in a penile avulsion with complete skin loss and heavy contamination. In rural settings, where penile avulsion due to traditional circumcision is common, honey should be considered as one of the dressing choices.

Biting the hand that feeds you: Management of human and animal bites

Bites from animal and humans represent a very small proportion of all the patients presenting to emergency departments, However, they require prompt medical and surgical intervention in order to minimise the risk of infection, that may lead to limb and life-threatening complications. In this review article we synthesise the existing literature for treatment of human and animal bites and offer practical considerations when managing bite injuries.

Human bite wounds as a portal of entry for infective endocarditis and purulent pericarditis: a very rare association

Human bites are an infrequent cause of emergency department visits and hospital admissions. There are rarely published cases of complicated infection, such as infective endocarditis. We present a rare case of a patient with acute infective endocarditis in a healthy native valve and purulent pericarditis from a human bite. A 40-year-old man with obesity suffered deep human bites by an adult woman, with two deep lesions in the anterior thorax and one superficial lesion in the upper abdomen and admitted in intensive care unit with septic shock and a persistent aortic murmur. Echocardiography described evidence of vegetation, perforation and severe regurgitation of aortic valve. Scanner described moderate pericardial effusion. Cardiac surgery was performed, with evidence of purulent pericardial effusion after pericardiotomy, and subsequently aortic valve replacement with a 25 mm bioprosthesis. The patient showed positive progress.

Challenging Dogma: Optimal Treatment of the "Fight Bite"

Background: The optimal treatment of human bites to the dorsal metacarpophalangeal region (ie, "fight bite") in the absence of gross purulence is controversial. Few studies have compared the outcomes of operative debridement with expectant wound care and oral antibiotics. Methods: We performed a retrospective chart review of all patients evaluated at a Level 1 trauma center over a 10-year period. We compared demographic and clinical characteristics of patients across treatment and outcome groups using the Fisher exact test. Logistic regression models were used to describe the relationships between the outcome and treatment variables. Results: We identified 115 patients with a mean age of 29 years. The mean follow-up was 51.8 days. Seventy-two (63%) patients were treated with antibiotics only. Thirty-two (28%) patients were treated with irrigation in the emergency department (ED) and expectant wound care. Eleven (9%) patients were treated with irrigation and debridement in the operating room. No demographic variables were found to correlate with the treatment selected. A 12% complication rate (major and minor) was observed. After adjusting for duration of follow-up and days to presentation, neither the treatment rendered nor the antibiotics selected influenced the rate of complications. Time to presentation >24 hours was the only variable associated with higher complication rate (P = .003). Conclusions: Not all fight bites require operative intervention. Irrigation in the ED with expectant wound care and oral antibiotics can be sufficient for patients presenting within 24 hours of injury in the absence of gross purulence.

Delay in the Diagnosis of Stable Slipped Capital Femoral Epiphysis

INTRODUCTION

Delays in the diagnosis of stable slipped capital femoral epiphysis (SCFE) is common due to the vague symptomatology and the lack of awareness of this entity by healthcare providers. Delays in the diagnosis of this condition can lead to poor outcomes for the patients. This study was designed to identify factors that contributed to delays in the diagnosis or the treatment of patients with SCFE seen at our institution.

METHODS

A retrospective chart review of patients with the diagnosis of a stable SCFE who had undergone screw stabilization between 1989 and 2010 at our hospital was performed. For each patient, demographic data, the date of initial onset of symptoms, the date of the first visit to the medical provider, the type of provider seen initially (orthopaedic surgeon or not), the date of diagnosis of SCFE, the type of physician who made the diagnosis (orthopaedic surgeon or not), and the date of surgery were recorded. For each patient, the presenting symptom was recorded as hip, thigh, or knee pain. The effect of demographic data, presenting symptoms, and the type of initial provider seen on the delay to diagnosis was studied using 2 Cox models.

RESULTS

A total of 149 patients with 196 stable SCFE were included. The average time from the first physician visit to diagnosis was 94 days in the group seen by a nonorthopaedic provider compared with an average of 2.9 days in the group seen by an orthopaedist (P<0.05). Diagnosis was made in 1 week only in 19% of the group seen by a nonorthopaedic provider versus 97% in the group seen by orthopaedic surgeons. It took significantly longer to be diagnosed with SCFE in patients who presented with initial knee pain (P=0.0097) compared with those who presented with hip pain at the initial visit.

CONCLUSIONS

This study shows a significant delay in the diagnosis of SCFE in the United States, particularly in patients seen by nonorthopaedic providers initially.

LEVEL OF EVIDENCE

Level III-prognostic.

[Mammal bite management]

BACKGROUND

Animal bites are a major public health problem, it is estimated that 2% of the population is bitten each year. Most bites are by dogs and the risk factors include young children, men, certain breeds of dogs and untrained dogs. The risk of infection after bites differs between animal species and depends on the animal teeth and oral flora.

CONCLUSIONS

Animal bites are still a major cause of morbidity in patients of all ages and have caused several preventable childhood deaths. These wounds often become infected. If the wound requires it, early surgical evaluation must be performed. The use of antibiotics is only recommended for high risk bite wounds.

Clenched fist injury complicated by septic arthritis and osteomyelitis treated with negative pressure wound therapy: One case report

We reported a 30 years old man who suffered a bite wound of the right hand in a fight. Two days after the injury, he was admitted in emergency because of stab wound above the head of the third metacarpal bone. He presented the swelling, redness, pain and fever. Primary revision confirmed only partial lesion of the extensor apparatus. During the following days, we recorded a deterioration of local findings and magnetic resonance imaging revealed osteomyelitis and septic arthritis of the thirdmetacarpophalangeal joint. The wound was then revised several times using negative pressure wound therapy in combination with intravenous antibiotics. After resolution of clinical and laboratory findings, the wound was finally closed by delayed primary suture. Clenched fist injury is a medical emergency that requires immediate surgical revision. We treated clenched fist injury with the development of septic arthritis and osteomyelitis with negative pressure wound therapy and obtained good outcomes.

Metacarpal Neck Fractures: A Review of Surgical Indications and Techniques

CONTEXT

Hand injuries are a common emergency department presentation. Metacarpal fractures account for 40% of all hand fractures and can be seen in the setting of low or high energy trauma. The most common injury pattern is a metacarpal neck fracture. In this study, the authors aim to review the surgical indications for metacarpal neck fractures, the fixation options available along with the risk and benefits of each.

EVIDENCE ACQUISITION

Literature review of the different treatment modalities for metacarpal neck fractures. Review focuses on surgical indications and the risks and benefits of different operative techniques.

RESULTS

The indications for surgery are based on the amount of dorsal angulation of the distal fragment. The ulnar digits can tolerate greater angulation as the radial digits more easily lose grip strength. The most widely utilized fixation techniques are pinning with k-wires, dorsal plating, or intramedullary fixation. There is currently no consensus on an optimal fixation technique as surgical management has been found to have a complication rate up to 36%. Plate and screw fixation demonstrated especially high complication rates.

CONCLUSIONS

Metacarpal neck fractures are a common injury in young and active patients that results in substantial missed time from work. While the surgical indications are well-described, there is no consensus on the optimal treatment modality because of high complication rates. Dorsal plating has higher complication rates than closed reduction and percutaneous pinning, but is necessary in comminuted fractures. The lack of an ideal fixation construct suggests that further study of the commonly utilized techniques as well as novel techniques is necessary.

Managing bite wounds

Animal and human bites are common in the United States. Although evidence-based practice guidelines have not been developed, bite wounds warrant an organized, standardized approach to care to help prevent complications. Such an approach involves first eliciting a history of the circumstances surrounding the bite and the patient's medical history. Next, basic bite wound care should be performed, including cleansing and irrigation of the wound. A good understanding of bite wound bacteriology and the situations in which antibiotics may be indicated is important. Finally, rabies and tetanus prophylaxis should be considered and appropriate follow-up care ensured.

The tooth, the whole tooth: an unusual fight bite with an unnoticed embedded tooth in the hand

A 19-year-old man presented to the plastic surgeons with a wound between his fourth and fifth metacarpophalangeal joints, with associated hand swelling and pain. He admitted to accidentally striking his brother in the mouth the previous evening. His brother reportedly made a hasty exit, and the patient dismissed the wound to his hand until waking up the next morning with swelling, pain and ascending lymphangitis. Radiographs revealed the unusual extent of his 'fight bite' injury with an entire human tooth embedded in his hand. Removal of the tooth and aggressive debridement was performed in theatre. Establishing an accurate account of events in these injuries can be difficult, with the orientation of the tooth in the soft tissues being more consistent with an uppercut than the reported jab. The patient made a good recovery following elevation, intravenous antibiotics, rigorous surgical debridement and postoperative hand therapy.

The karapandzic flap in lower lip reconstruction

Human bite injuries are both deceptive and challenging in their presentation and management. They are particularly notorious due to the polymicrobial nature of human saliva inoculated in the wound and the risk they pose for transmission of infectious diseases. Early treatment, appropriate prophylaxis and surgical evaluation are the key to achieving desired treatment outcomes. Here we present a case report of human lip bite with significant tissue loss that required reconstruction. The reconstructive techniques are usually varied but the ultimate objectives of treatment are to achieve healing, function, and aesthetics. Through this article, we have tried to focus on the diagnostic features, reconstructive procedure as well as other recommended treatment options for human lip bites based on the current available evidence.

"Fight-bite": not just a hand problem

Human bite wounds around the knee are rarely seen, yet may require the same urgent attention as a fight bite to the hand. Two cases of polymicrobial septic arthritis of the knee secondary to a human bite wound are described. In both the cases, the diagnosis of the septic arthritis was delayed because the intra-articular wound was unrecognized. The injuries were initially deemed superficial and managed with local wound care. In each case, the knee was flexed at the time of injury and the quadriceps tendon was penetrated by a tooth which inoculated the knee joint. Septic arthritis of the knee presented, in both cases, 72 hours after the injury. These infections proved challenging to treat and required multiple surgeries and prolonged antibiotic therapy. The "fight bite" phenomenon of the hand is widely recognized and the same phenomenon can occur at the knee.

Bite injuries to the hand: microbiology, virology and management

Bites to the human hand, be it from a pet, a stray animal or even a fellow human, may often have dire consequences for the person suffering the insult. Bites by mammals are a common problem and they account for up to 1% of all visits to hospital emergency rooms, in the UK. Clenched fist injuries to the mouth ('fight bite') are notorious for being the worst human bites. Bite injuries of the hand and their related infections must be monitored vigilantly and managed proactively, by experts in this field of surgery. In this review article we discuss the associated microbiology and virology of these injuries as well as their management.

An analytical study of Mammalian bite wounds requiring inpatient management

BACKGROUND

Mammalian bite injuries create a public health problem because of their frequency, potential severity, and increasing number. Some researchers have performed fragmentary analyses of bite wounds caused by certain mammalian species. However, little practical information is available concerning serious mammalian bite wounds that require hospitalization and intensive wound management. Therefore, the purpose of this study was to perform a general review of serious mammalian bite wounds.

METHODS

We performed a retrospective review of the medical charts of 68 patients who were referred to our plastic surgery department for the treatment of bite wounds between January 2003 and October 2012. The cases were analyzed according to the species, patient demographics, environmental factors, injury characteristics, and clinical course.

RESULTS

Among the 68 cases of mammalian bite injury, 58 (85%) were caused by dogs, 8 by humans, and 2 by cats. Most of those bitten by a human and both of those bitten by cats were male. Only one-third of all the patients were children or adolescents. The most frequent site of injury was the face, with 40 cases, followed by the hand, with 16 cases. Of the 68 patients, 7 were treated with secondary intention healing. Sixty-one patients underwent delayed procedures, including delayed direct closure, skin graft, composite graft, and local flap.

CONCLUSIONS

Based on overall findings from our review of the 68 cases of mammalian bites, we suggest practical guidelines for the management of mammalian bite injuries, which could be useful in the treatment of serious mammalian bite wounds.

Managing human bites

Human bites are frequently overlooked in making a diagnosis in the emergency room. They are particularly notorious due to the polymicrobial nature of human saliva inoculated in the wound and the risk they pose for transmission of infectious diseases. Early treatment, appropriate prophylaxis and surgical evaluation are the key to achieving desired treatment outcomes. Through this article, we have tried to summarize the diagnostic features, complications as well as the recommended treatment alternatives for human bites based on the current available evidence.

Risk management and avoiding legal pitfalls in the emergency treatment of high-risk orthopedic injuries

Avoiding legal pitfalls of orthopedic injuries in the emergency department (ED) requires an understanding of certain high-risk injuries, their presentation, evaluation, and disposition. Various pitfalls pertaining to both upper and lower extremity injuries are discussed in detail, with recommendations regarding the history, physical examination, and radiographic techniques that minimize the risk inherent in these injuries. When approaching these injuries in the ED, a high level of suspicion coupled with appropriate evaluation and management will allow the practitioner to avoid mismanagement of these potential pitfall cases.

Hand Trauma Pitfalls: A Retrospective Study of Fight Bites

Clench fist or fight bite injuries are associated with some of the worst types of infective complications but their mechanism is often poorly understood. In a retrospective case series, 34 patients seen between 1998 and 2004 presented to a local hand surgery unit with confirmed human bite hand injuries. Seventy-six percent presented with infective complications with a mean delay in presentation of 4 days. Eighty percent of patients were clench fist injuries (CFI) (open joints in 59% and tendon injuries in 63%). Using an aggressive treatment policy including early surgical and antibiotic intervention, most patients achieved good results functionally (full range of movement was achieved in 83% of those with CFI which completed follow-up (44%)). High rates of non-compliance and incomplete follow-up was noted. Major long-term complications including limited range of movement and osteomyelitis was low and suggests the policy of prompt and comprehensive surgical and medical intervention is the optimal treatment option. A brief but in-depth discussion of the specific anatomical pitfalls is included.

Emergency Management of Difficult Wounds: Part I

Emergency physicians treat millions of wounds annually in the United States. In 2004 approximately 6.4 million open wounds were seen in United States emergency departments, representing approximately 5.8% of all visits. This article discusses difficult traumatic wounds that emergency physicians encounter on a daily basis, including mammalian bites, puncture and high-pressure wounds, and crush injuries, with special emphasis given to individuals at high risk for infectious complications. Information is provided on epidemiology, pathophysiology, management, and treatment of various complicated wounds. The authors highlight available guidelines, provide the best evidence available, and provide recommendations when data are limited.

Continuity of interpersonal violence between Nubian communities

Modern communities affiliated with the same culture have been shown to experience comparable levels of interpersonal violence, no matter what their size. It was hypothesized that a similar relationship would exist among ancient rural and urban people, but that accident-related trauma may be more prominent among rural dwellers due to their activity base. Through an analysis of antemortem trauma, this investigation contrasted the injury profile of Nubian adult villagers (N = 55) from the Kerma period (2500-1750 BC) to that of their urban neighbors (N = 223) at Kerma (2050-1500 BC). The injury pattern associated with interpersonal violence (cranial injury, direct-force ulna fractures, and multiple injuries) was similar between the two samples, as hypothesized. The rural group sustained significantly more nonviolence-related injuries that suggested occupational or environmental influences. The more severe cranial injuries observed among urban people are attributed to a preference for more lethal hand-wielded objects that may have accompanied increasing local tensions and incursions into Egypt during the 17th Dynasty.
