  • Article: The effects of surgical delay on the outcome of pediatric supracondylar humeral fractures.
    [show abstract] [hide abstract]
    ABSTRACT: Occasionally, the treatment of a pediatric supracondylar humeral fracture is delayed owing to lack of an available treating physician, necessitating transfer of the child, or delay in availability of an operating room. The purpose of this study is to prospectively evaluate whether delayed pinning of these fractures affects the outcome or number of complications. We reviewed information that was prospectively collected on 145 pediatric supracondylar humeral fractures that were treated by closed reduction and percutaneous pinning, with a minimum follow-up of 8 weeks. To determine the effect of delayed treatment, we compared a group of fractures that was treated within the first 21 hours after their presentation to our urgent care center (Group A) with a group that was treated after more than 21 hours (Group B). We compared the following variables: need for open reduction, length of surgery, length of hospitalization, the presence of neurologic complications, vascular complications including compartment syndrome, pin tract infection, loss of fixation, final carrying angle, range of motion, and outcome. Overall, the mean time from presentation to surgery for both groups was 52 hours. This interval was greater for Gartland type II fractures (65 h) than for Gartland type III fractures (19 h) (P=0.00001). There was no need for an open reduction in either group. There were no significant differences between the groups regarding iatrogenic nerve injuries, vascular complications, compartment syndromes, surgical time, final carrying angle, range of motion, and outcome. The results of this prospective study found that a delay in pinning closed supracondylar humeral fractures in children did not lead to a higher incidence of open reduction or a greater number of complications. Although the urgency of treating any child with a supracondylar fracture should be individualized, our study suggests that most of these injuries can be managed safely in a delayed fashion without compromising the clinical outcome. We recommend careful monitoring of any patient with type 3 injury whose treatment is delayed. II.

  • Article: Peripheral neuropathy of the upper extremity: medical comorbidity that confounds common orthopedic pathology.
    Joshua G Bales, Roy Meals
    [show abstract] [hide abstract]
    ABSTRACT: In the orthopedic patient, the diagnosis of a compression neuropathy may be straightforward. However, various medical comorbidities can obscure this diagnosis. It is paramount for the practicing orthopedic surgeon to have an appreciation for the medical pathology of common axonal neuropathies to properly diagnose, treat, and refer a patient with altered sensation in the upper extremity. The prevalence of diabetes in the United States is 10%, and roughly 20% of diabetic patients have peripheral neuropathy. In addition to diabetes, 32% of heavy alcohol users present with polyneuropathy. With advancements in the treatment of human immunodeficiency virus/acquired immunodeficiency syndrome clinicians may see the long-term effects of the virus manifested as axonal neuropathies and extreme allodynia. In some regions of the world, Hansen's disease usurps diabetes as the most common cause of polyneuropathy. Based on patient demographics and social habits, Lyme disease, multiple sclerosis, and syphilis can all manifest as polyneuropathies. Understanding the common medical causes of neuropathy will aid the orthopedic surgeon in differentiating simple compression neuropathies from diseases mimicking or confounding them.

  • Article: Electrocautery-induced asystole in a scoliosis patient with a pacemaker.
    [show abstract] [hide abstract]
    ABSTRACT: Pediatric heart condition management may include a variety of implanted cardiac devices. Monopolar electrocautery (Bovie) produces significant electromagnetic interference to these devices. This interference can alter the function of a cardiac generator resulting in a variety of complications including impaired cardiac output and asystole. We report the case of a 16 plus 2-year-old girl who presented with idiopathic scoliosis and a past medical history significant for complete congenital heart block treated with a DDD*** pacemaker. During surgery, the use monopolar electrocautery caused the patient to develop asystole and loss of pulsatile blood pressure. Electrocautery was subsequently terminated, the patient then returned to a normal sinus rhythm and blood pressure normalized.

  • Article: Bilateral patellar dislocation associated with alpha-mannosidase deficiency.
    [show abstract] [hide abstract]
    ABSTRACT: Mannosidosis is an extremely rare genetic disease characterized by a deficiency of the lysosomal enzyme, alpha-mannosidase. This enzyme is necessary for cleavage of mannose from many glycoproteins. In the absence of this enzyme, mannose accumulates in cells throughout the body, including the joints and the synovium. This disease causes many skeletal changes including dysostosis multiplex, synovial hypertrophy, and Charcot-type joints. We report the case of a girl, aged 9 years and 6 months, who developed bilateral patellar dislocation and severe synovial hypertrophy secondary to alpha-mannosidase deficiency. Her disease was further complicated by Charcot elbow and bilateral hip and elbow avascular necrosis.
