Prospective Patient Reported Outcomes (PRO) Study Assessing Outcomes of Surgically Managed Ankle Fractures.

Foot Ankle Int 2020 02 4;41(2):206-210. Epub 2019 Dec 4.

Department of Orthopedics, Division of Foot & Ankle Surgery, Northwestern University Feinberg School of Medicine, Chicago, IL, USA.

Background: Ankle fractures are a common cause of morbidity that have increased in incidence over the past decade. The purpose of this study was to compare the outcomes and prognosis of various fracture subtypes by using 2 validated patient-reported outcome measures: the Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function (PF) and Pain Interference (PI) Computer Adaptive Tests (CATs).

Methods: Twelve-month postoperative PF and PI CATs were collected for 126 ankle fracture patients presenting between 2014 and 2017. Patients were stratified by ankle fracture subtype and refined by the presence/absence of concomitant deltoid injury or posterior malleolar fracture. Patients defined as members of vulnerable populations and patients presenting more than 2 weeks from time of injury or with prior acute ipsilateral fracture were excluded. The distribution of PF and PI T scores were assessed via a Shapiro-Wilk test and a 1-way analysis of variance. If significant differences were found between groups, pairwise comparisons were tested via Dwass, Steel, and Critchlow-Fligner multiple comparison analysis.

Results: Mean values for the PROMIS PF and PI for each fracture subtype were calculated and compared to reference population mean (SD) T scores of 50 (10): isolated lateral malleolar (PF: 50/PI: 51), isolated medial malleolar (PF: 52/PI: 49), bimalleolar (PF: 48/PI: 50), trimalleoar (PF: 47/PI: 51), isolated posterior malleolar (PF: 53/PI: 44), and isolated syndesmotic injury (PF: 60/PI: 46). Shapiro-Wilk test indicated a nonnormal distribution for the postoperative PROMIS PF T scores across all fracture patients ( = .0421).

Conclusion: Operative fixation of an ankle fracture was able to return most patients to the population mean with regard to PROMIS function and pain regardless of fracture type.

Level Of Evidence: Level II, prospective comparative study.

A Cadaveric Study of Cutaneous Vascular Anatomy about the Elbow Using Computed Tomography Angiography.

Clin Anat 2019 May 19;32(4):509-514. Epub 2019 Feb 19.

University of Arkansas for Medical Sciences, Little Rock, Arkansas.

The posterior approach is a commonly employed exposure of the elbow that provides excellent visualization and efficacy for various orthopedic procedures, including total elbow arthroplasty (TEA) and fracture care. The posterior approach to the elbow has been associated with an increased rate of wound complications, including infection, skin necrosis, and wound dehiscence. Despite an association between these complications and decreased elbow perfusion, data regarding the intrinsic anatomic etiology for preferential complications in this area has been scarcely reported in the literature. This study characterizes the subdermal and cutaneous vascular perfusion about the elbow by describing the predominant direction of circulation, subdermal anastomoses, and volume of perfusion through cadaveric modeling using computed tomography angiography (CTA). Fifteen upper extremity cadaver specimens were prepared with injection of radiographic contrast directly into the axillary artery immediately preceding CTA imaging of each specimen. Sectra IDS7 software for Windows was used for analysis of all images to produce superimposed axial and 3-D reconstructions of each CTA series. From these images it was discerned that the predominant direction of flow in the posterior elbow integument is anterior medial to posterior lateral. Both the posterior medial and posterior lateral subdermal vascular networks emanate from proximally derived medial arterial sources with few anastomoses and minimal collateral perfusion from the anterolateral location. Consequently, it is important to preserve medial subdermal vascular structures to prevent ischemic wound complications. This is especially true in previously incised elbow integuments. Clin.

High Relative Expression of Pannexin 3 (PANX3) in an Axillary Sweat Gland Carcinoma With Osteosarcomatous Transformation.

Am J Dermatopathol 2016 Nov;38(11):846-851

*Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN; Departments of †Pathology, ‡Dermatology, and §Radiology, University of Arkansas for Medical Sciences, Little Rock, AR; ¶Division of Hematology/Oncology, Department of Internal Medicine, University of Arkansas for Medical Sciences, Little Rock, AR; Departments of ‖Orthopedic Surgery and **Pathology, University of Arkansas for Medical Sciences, Little Rock, AR.

Primary cutaneous sweat gland carcinomas (SGCs) are rare tumors that commonly involve axillae, have a high local recurrence rate, and rarely show sarcomatoid transformation. A 68-year-old man presented with rapid enlargement of a previously stable, asymptomatic pea-sized nodule in the left axilla. Initial excision (with positive surgical margins) at another institution showed characteristic histologic features of a high-grade osteosarcoma and molecular analysis using a 92-gene real-time quantitative reverse transcription-polymerase chain reaction assay confirmed a diagnosis of osteosarcoma with 96% certainty. Notably, the molecular assay demonstrated consistently high relative expression of pannexin 3 (PANX3), a gene involved in normal osteoblast differentiation which, when highly expressed, strongly predicts osteosarcoma per the assay's algorithm. However, on further histologic review, the tumor also contained focal cystic areas, nests, and ducts composed of malignant epithelial cells reminiscent of SGC; these areas directly transitioned into the osteosarcomatous component and were strongly positive for pancytokeratin, CK7, and p63. Within 2 weeks, the lesion recurred and grew rapidly, prompting complete resection, histologic sections of which showed high-grade osteosarcoma without residual epithelial elements. This is the fifth report, to our knowledge, of osteosarcomatous transformation in a SGC, and the only report to date including molecular data. This case demonstrates that osteosarcoma arising from a SGC has a similar molecular profile to de novo primary osteosarcoma of bone. It also emphasizes the importance of histopathologic findings as the established diagnostic gold standard and the need to interpret molecular results within the clinical context.

Stress Fractures of the Distal Femur Involving Small Nonossifying Fibromas in Young Athletes.

Orthopedics 2016 Nov 26;39(6):e1197-e1200. Epub 2016 Jul 26.

Small nonossifying fibromas (ie, fibrocortical defects) are incidental findings commonly seen on radiographs of young patients evaluated for extremity pain or sport-related trauma. Although pathological fractures have been reported in larger lesions, the subcentimeter, intracortical defects are not generally thought to predispose to pathological fractures. The authors report on 2 young athletes who presented with knee pain after initiating conditioning exercise programs (cross-training). Both were diagnosed with transverse metaphyseal stress fractures involving fibrous cortical defects of the distal femur. Initial radiographs were interpreted without evidence of fractures. However, subsequent magnetic resonance imaging was informative, suggesting that magnetic resonance imaging may have value in identifying potential stress reactions in young athletes. In addition, subsequent plain radiographs of both patients showed subperiosteal new bone formation in these nondisplaced fractures, suggesting that serial radiographs and close clinical follow-up are warranted for patients with persistent symptoms. The authors propose that, in the appropriate clinical setting, the presence of a small nonossifying fibroma may be a clinical indication that further evaluation is needed when plain radiographs show normal findings, as the defect could be an unrecognized area of fracture initiation.

"High five to healthy living": a health intervention program for youth at an inner city community center.

J Community Health 2012 Feb;37(1):1-9

Morehouse School of Medicine, Atlanta, GA 30312, USA.

Providing developmental programs to inner-city youth is a key component to promoting healthy lifestyles in urban communities. In this study, 46 adolescents, predominately African American youth (age 11-14), participated in the "High Five for Healthy Living" hygiene intervention program hosted at the NFL Youth Education Town of the Boys and Girls Club of Atlanta. Windshield surveys, key informant interviews and focus groups were conducted in order to identify the needs of the surrounding community and subsequently plan and implement a 5 week developmental module to meet these needs. Weekly modules were conducted focusing on oral hygiene, hand washing, physical activity, male/female personal hygiene, and nutrition/food safety. Surveys administered showed that a large percentage of students exhibited behavioral change following the completion of each module: 42% for oral hygiene, 88% for hand washing, 75% for physical activity, 88% for personal hygiene and 50% for nutrition/food safety. From these findings, it is evident that that African American adolescents can benefit from developmental programs targeted to address their specific community needs, and as a result implement personal lifestyle changes. Such interventions could potentially decrease in the prevalence of certain preventable diseases endemic to many low socioeconomic inner city communities.
