Analysis of Oklahoma amputation trends and identification of risk factors to target areas for limb preservation interventions.

Objective: Annual trends of lower extremity amputation due to end-stage chronic disease are on the rise in the United States. These amputations are leading to massive expenses for patients and the medical system. In Oklahoma, we have a high-risk population because access to care is low, the number of uninsured is high, cardiovascular health is poor, and our overall health care performance is ranked 50th in the country.

Bilateral Digital Ischemia Secondary to Heparin-Induced Thrombocytopenia with Subsequent Limb Salvage: A Case Study.

Heparin-induced thrombocytopenia (HIT) is a prothrombotic state caused by the buildup of platelet factor 4 antibodies with decreased platelet count caused by heparin therapeutic or prophylactic therapy. It is important to detect this complication, especially in critically ill patients and cardiac patients. Detection of HIT can be demonstrated by positive antibodies in a HIT panel.

Development of Multiple Epidermal Inclusion Cysts After Radiofrequency Microtenotomy for Plantar Fasciitis: A Case Report.

Epidermal inclusion cysts are slowly developing intradermal lesions which form after the implantation of epidermal tissue into the dermal tissue. Epidermal cysts occur infrequently in the foot, but can occur after traumatic episodes, including surgically induced trauma. Epidermal inclusion cysts have been described as a complication of minimally invasive foot and ankle surgery; however, they have been described infrequently as a complication of radiofrequency microtenotomy.

Level of Agreement Between Systematic Doppler Examination of the Lower Extremity and Diagnostic Angiography in the Setting of Peripheral Arterial Disease.

Background: The objective of this investigation was to determine the level of agreement between a systematic clinical Doppler examination of the foot and ankle and diagnostic peripheral angiography.

Methods: The described Doppler examination technique attempted to determine the patency, quality, and direction of the flow through the dorsalis pedis artery, posterior tibial artery, terminal branches of the peroneal artery, and vascular arch of the foot. These results were then compared with angiographic distal run-off images as interpreted by a blinded vascular surgeon.

Printed 3-Dimensional Computed Tomography Scanned Ankle Fractures as an Educational Instrument.

The evaluation of and treatment protocols for ankle fractures represents an important aspect of the education of podiatric medical students. The objective of this investigation was to examine the feasibility of and student satisfaction with using 3-dimensional (3D) printed bone models representative of the Lauge-Hansen classification. The computed tomography scans of subjects with actual rotational ankle fractures representative of the Lauge-Hansen classification were identified and extracted into a format compatible with a 3D printer.

Level of Agreement with the Microscopic Analysis of Joint Aspirate for the Diagnosis of Gout in the Lower Extremity.

Background: Although clinical findings, laboratory serum markers, and radiographic images are also used, the purported gold standard or standard reference test for the diagnosis of gout is microscopic analysis of aspirated joint fluid. This observational investigation sought to identify the level of agreement with the microscopic analysis of joint fluid aspirate for the diagnosis of gout in the lower extremity between two departments in a single health-care center.

Methods: A retrospective medical record review identified consecutive patients seen for suspected gout who underwent diagnostic joint aspiration.

Soft Tissue Reconstruction with Diabetic Foot Tissue Loss.

Although substantial advances have been made in treatment of diabetic foot disease with respect to patient education, preventative measures, early intervention, and prophylactic procedures, most surgical interventions for this condition are reactionary. Patients still primarily present to emergency departments with acute infections and tissue necrosis. The surgical intervention for this results in soft tissue deficit, often with partial foot amputation, through excisional debridement of pathologic tissue.

Quantitative Assessment of the Obliquity of the First Metatarsal-Medial Cuneiform Articulation.

The so-called obliquity of the first metatarsal-medial cuneiform articulation has been described as an atavistic trait of human foot morphology, and it is commonly proposed as a relative risk factor for development of the hallux abductovalgus (HAV) deformity. The objectives of this investigation were to 1) provide descriptive normative radiographic data on a series of first metatarsal-medial cuneiform articulations and 2) correlate these findings to other common radiographic parameters used to define the HAV deformity. We measured radiographic parameters including the first intermetatarsal angle, hallux abductus angle, tibial sesamoid position, Engel's angle, and 2 measures of obliquity in the transverse and sagittal planes on a consecutive series of 136 weightbearing foot radiographic projections from subjects without a history of foot/ankle surgery or fracture/dislocation.

Triplanar Quantitative Radiographic Analysis of the First Metatarsal-Phalangeal Joint in the Hallux Abductovalgus Deformity.

Although hallux abductovalgus (HAV) is widely considered to be a triplanar deformity involving the transverse, sagittal, and frontal planes, most of the published literature has focused on evaluating the deformity in only the transverse plane, and we are unaware of any investigation objectively evaluating the relationship among the 3 planes in the setting of HAV deformity. The objective of this investigation was to quantitatively evaluate radiographic measurement of the relationship between the transverse, sagittal, and frontal planes in the HAV deformity. Anteroposterior, lateral, and sesamoid axial radiographs from 42 consecutive feet were evaluated with measurement of the first intermetatarsal angle, hallux abductus angle, metatarsal sesamoid position, first metatarsal inclination angle, sesamoid rotation angle, and tibial sesamoid grade.

U.S. State Driving Regulations Relevant to Foot and Ankle Surgeons.

The effect of lower extremity pathology and surgery on automobile driving has been a topic of contemporary interest, because these conditions can be associated with impaired driving function. We reviewed the U.S.
