AM17 International Poster 008: Investigating the “Weekend Effect 9400 West Higgins Road, Suite 305 Rosemont, IL 60018-4975 Phone: (847) 698-1631 FAX: (847) 430-5140 E-mail: [email protected] It is my pleasure to provide the OTA Annual Meeting welcome for the sec- ond consecutive year. This anomaly is related to an organizational shift in the timing for transition of OTA held offices and positions from the Spring AAOS to the Fall OTA meeting. When the OTA was established, some 30 years ago, there was no OTA Annual Meeting. There was no OTA specific venue or opportunity for gathering, sharing, learning, educating, partner- ing, or doing OTA business. Since 1985, our Annual Meeting has grown from nonexistent to the premier orthopaedic trauma related meeting in the world. The timing shift for transition affected all committees. The Program William M. Ricci, MD Committee was no exception. Last year Mike McKee did double duty as the Program Committee Chair and Second President- Elect positions and Mike Gardner entered as Co-Chair of the Program Committee. Rather than following the normal two-year cycle in their Pro- gram Committee leadership duties, Mike McKee rotated off after one year to assume Presidential Line responsibilities, and Mike Gardner assumed the helm of the Program Committee a year early. Stephen Kottmeier joined the Program Committee as co-Chair. Despite the disturbance in normal cadence, the 2018 OTA Annual Meeting in Orlando, FL, as you will see, represents an evolution toward a more robust, more comprehensive, and more modern Annual Meeting sure to be our best yet. A testament to the commitment and dedication of all our member volunteers and the hard work of our OTA staff. Thanks to all!! Another exciting launch at this year’s Annual Meeting is OTA Online Trauma Access. OTA Online is a one stop online portal for educational material related to orthopaedic trauma. It will house the largest, most comprehensive, peer reviewed library of technique videos available. OTA Online will also include access to three Rockwood & Green titles: Rockwood & Green Textbook of Fractures in Adults/Children including a new living textbook edition Rockwood & Green Live that will provide consistent up-to-date material and the in demand Rockwood & Green On-Call a quick reference, bullet point resource based on the Rockwood & Green text. OTA Online will also provide access to the Journal of Orthopaedic Trauma, OTA International (OTA’s new open access journal), and forthcoming OTA Orthopaedic Trauma Textbook Series (targeted monographs to the most relevant clinical issues). This launch is the culmination of several years’ effort and a partnership with our publisher oltersW Kluwer. Finally, OTA Online will include Industry Channels where our corporate partners will showcase educational and reference content specific to their products. Again, hearty thanks to all involved for their tireless efforts to makeOTA Online a reality. I hope you will agree with our OTA Board of Directors that there is no better place or time than the OTA Annual Meeting to gather, share, learn, educate, partner, do OTA business, and now transition our offices and positions. Enjoy the meeting and please visitOTA Online often and encourage colleagues and trainees to visit often as well.

  • A Case of Bilateral Calcaneal Fracture, Following Fall from 35 Feet

The calcaneus is the most frequently fractured tarsal bone. Tarsal bone fractures account for about 2% of all adult fractures. Of these, 60% are calcaneus fractures.The heel bone is often injured in a high-energy collision where other parts of the skeleton are also injured. In up to 10% of cases, the patient can also sustain a fracture of the spine, hip, or the other calcaneus. Injuries to the calcaneus often damage the subtalar joint and cause the joint to become stiff. This makes it difficult to walk on uneven ground or slanted surfaces. Case Report: A 24 year old male, working as a lift operator presented to the casualty of the hospital after the elevator broke down and came down in a free fall from about a height of 4 stories (35 feet). He presented along with the other occupants of the lift who also sustained calcaneal fractures.The case on arrival was subjected to ATLS protocol and through radiologic work up was done. Following a period of 12 days post trauma he was operated for bilateral calcaneal fractures and discharged 10 days post operatively.

  • Deep Tissue Injury
    Deep Tissue Injury Overview Deep tissue injury is a term proposed by NPAUP to describe a unique form of pressure ulcers. These ulcers have been described by clinicians for many years with terms such as purple pressure ulcers, ulcers that are likely to deteriorate and bruises on bony prominences (Ankrom, 2005). NPAUP’s proposed definition, is “A pressure-related injury to subcutaneous tissues under intact skin. Initially, these lesions have the appearance of a deep bruise. These lesions may herald the subsequent development of a Stage III-IV pressure ulcer even with optimal treatment.”(NPAUP, 2002). Why is it important to have another label for pressure ulcers? Aren’t four stages enough? Perhaps not, because deep tissue injury represents a dangerous lesion due to its potential for rapid deterioration. Proper labeling will afford clinicians a more accurate diagnosis, and lay a foundation for the development of efficacious interventions. Background Shea (1975) is often credited with labeling the stages of pressure ulcers, and his descriptions of four depths of ulcers were adapted by IAET, AHCPR, and NPUAP. Missing from that four stage system label is deep tissue injury. However, Shea did not forget them in his review. He described ulcers that appear innocent yet conceal a deep, potentially fatal lesion. In 1873 Paget may have been the first to describe deep tissue injury describing purple areas with sloughing of tissue and large cavities once they open. In 1942, Groth created deep, “malignant pressure sores” in an animal model in a series of experiments that began in deeper tissues and spread to the surface.

  • Calcaneal Fracture and Rehabilitation
    1 Calcaneal Fracture and Rehabilitation Surgical Indications and Considerations Anatomic Considerations: The calcaneus articulates with the talus superiorly at the subtalar joint. The three articulating surfaces of the subtalar joint are the: anterior, middle, and posterior facets, with the posterior facet representing the major weight-bearing surface. The subtalar joint is responsible for the majority of foot inversion/eversion (or pronation/supination). The interosseous ligament and medial, lateral, and posterior talocalcaneal ligaments provide additional support for the joint. The tibial artery, nerve, posterior tibial tendon, and flexor hallucis longus tendon are located medially to the calcaneus and are at risk for impingement with a calcaneal fracture, as are the peroneal tendons located on the lateral aspect of the calcaneus. The calcaneus serves three major functions: 1) acts as a foundation and support for the body’s weight, 2) supports the lateral column of the foot and acts as the main articulation for inversion/eversion, and 3) acts as a lever arm for the gastrocnemius muscle complex. Pathogenesis: Fractures of the calcaneal body, anterior process, sustentaculum tali, and superior tuberosity are known as extra-articular fractures and usually occur as a result of blunt force or sudden twisting. Fractures involving any of the three subtalar articulating surfaces are known as intra-articular fractures and are common results of: a fall from a height usually 6 feet or more, a motor vehicle accident (MVA), or an impact on a hard surface while running or jumping. Intra-articular fractures are commonly produced by axial loading; a combination of shearing and compression forces produce both the primary and secondary fracture lines.

Besides the intense pain and distress caused to the patient, the gross displacement may cause pressure necrosis of the anterior skin, vascular and neurologic impairment, and compressive damage to the cartilage of the talar dome and tibia joint surface. Immediate reduction of the fracture, and thereby relieving the compromised neurovascular structures provides overall good results. There are several case reports and series reporting on non-reducible fracture-dislocations of the ankle1-3.

At the same time, successful closed manipulations in an ankle joint fracture and dislocation are dicult because of the bula attachment at the posterolateral ridge of the tibia or at the fractured end of the posterior tibia. Patient concerns: A 56-year-old man visited the hospital for further evaluation of a swollen, deformed right ankle resulting from a tumble 4 hours ago.

Methods: Fifty-six members of the special force brigade of the military who had sustained ankle fractures during parachute land- ings between January 2005 and April 2010 were retrospectively analyzed. The injury sites and fracture sites were identified and the fracture types were categorized by the Lauge-Hansen and Weber classifications. Follow-up surveys were performed with re- spect to the American Orthopedic Foot and Ankle Society ankle-hindfoot score, patient satisfaction, and return to preinjury activity. Results: The patients were all males with a mean age of 23.6 years. There were 28 right and 28 left ankle fractures. Twenty-two patients had simple fractures and 34 patients had comminuted fractures. The average number of injury and fractures sites per person was 2.07 (116 injuries including a syndesmosis injury and a deltoid injury) and 1.75 (98 fracture sites), respectively.
