Anatomical Parameters for Occipital Condyle Screws: An Analysis of 500 Condyles Using CT Scans.

STUDY DESIGN: Retrospective observational study. OBJECTIVE: To establish occipital condyle dimensions (length, width, height), as well as the medialization angle necessary for safe occipital condyle screw placement in occipitocervical fixation. METHODS: Between 1/2014-6/2014, patients who presented to a single level 1 academic trauma center emergency room and received computed tomography (CT) imaging of the cervical spine as part of routine clinical care were identified. After excluding patients with cervical fractures, neoplastic disease, or infection, 500 condyles representing 250 patients were analyzed. Condyle length, height, and width (all reported in millimeters [mm]) were evaluated on the sagittal, coronal, and axial series, respectively. Medialization angle (reported in degrees) was evaluated on the axial series of CT imaging. Measurements were compared by sex and age. RESULTS: The average condyle length, width, and height were 18.6 millimeters (mm) (range, 14.5-23.0 mm), 10.5 mm (range, 7.4-13.8 mm), and 11.3 mm (7.1-15.3 mm), respectively. Additionally, the average occipital condyle medialization angle was 23° (range, 14-32°). Occipital condyles of men were significantly longer, wider, and taller (all comparisons, p < 0.05). The medialization angle was significantly steeper for women than men (p < 0.05). No measurement differences were appreciated by age. CONCLUSION: Our findings are similar to previous studies in the field; however, length appears slightly shorter. Further, measurement differences were appreciated by sex but not age. Thus, our measurement findings emphasize the importance of preoperative planning utilizing individual patient anatomy to ensure safe placement of occipital condyle screws for optimal outcomes.

Evaluation and Treatment of Posterior Tibialis Tendon Insufficiency in the Elderly Patients.

INTRODUCTION: Posterior tibialis tendon insufficiency is the most common cause of adult acquired flatfoot deformity in elderly patients. We performed a literature search of primary and secondary journal articles pertaining to posterior tibialis tendon insufficiency in the geriatric population. We examined relevant data from these articles regarding current evaluation in addition to both conservative and advanced treatment approaches that correspond to disease severity. SIGNIFICANCE: There is a paucity of literature to guide treatment of posterior tibialis tendon insufficiency in the elderly, and this condition may be more prevalent in geriatric patients than previously realized. RESULTS: Posterior tibialis tendon insufficiency is an acquired defect that affects 10% of the geriatric population and disproportionately affects women. It is typically caused by degenerative changes. There are four primary stages of posterior tibialis tendon with subcategorizations that range from mild to severe. Conservative treatment with a variety of available ankle braces and non-steroidal anti-inflammatory medications are typically used to treat the first and second stage disease. Surgical repair is warranted for advanced second stage and above posterior tendon insufficiency. A variety of techniques have been proposed, and can include tendon transfer, hindfoot fusion, and even total ankle arthroplasty in extreme cases. CONCLUSION: Posterior tibialis tendon insufficiency causes marked discomfort and alters normal gait biomechanics. Elderly patients typically present with more severe manifestations of the disease. For patients requiring surgery, and especially geriatric patients, the ideal treatment is thought to be a procedure that is minimally invasive in order to maximize positive outcomes for elderly patients. More work is needed to examine clinical and radiographic outcomes of geriatric patients treated for posterior tibialis tendon insufficiency.

Interest in Orthopedic Surgery Residency: A Google Trends Analysis.

Google Trends, a powerful online search tool, was used to evaluate the association between the United States applicant pool for orthopedic surgery residency and Internet queries for orthopedic residency and orthopedic salary. From 2006 to 2015, searches for orthopedic salary and orthopedic residency were conducted by Google Trends. Data from the National Residency Match Program (NRMP) in the same time period was plotted and subsequently compared to the Google Trends results. From 2006 to 2015, Google Trends demonstrated an increase in orthopedic residency queries with the largest increase between 2008 and 2010. Orthopedic salary searches increased over the study period, with the sharpest increase from 2008 to 2009. NRMP demonstrated an increase over the study period in U.S. medical school orthopedic surgery applicants and positions filled. The Google Trends analysis mirrored the data from the NRMP, suggesting that online search tools could be of important predictive value for medical students' interest in orthopedic surgery residency.

Validity of QuickDASH at day of surgery versus day of initial consultation: Does informed consent make a difference?

INTRODUCTION: The trend toward requiring explicit consent from patients participating in observational research increases time and resources required to perform such research. Informed consent introduces the potential for "consent bias"-either through selection bias or through the "Hawthorne effect," where patients may alter responses based upon the awareness of participation in a study, thus potentially limiting its applicability to a generalized orthopedic practice. We hypothesized that administering Quick Disabilities of the Arm, Shoulder, and Hand Questionnaire (QuickDASH) to patients on the day of surgery with informed consent would alter responses in a statistically and clinically meaningful way compared to patients who complete QuickDASH as a quality control measure. METHODS: We previously instituted the QuickDASH questionnaire as the standard new patient intake and postoperative questionnaire for quality assurance purposes. We retrospectively reviewed data on a cohort of patients who underwent isolated carpal tunnel release (CTR) who had completed preoperative and postoperative QuickDASH forms without providing consent for study participation. Next, a cohort of patients scheduled to undergo isolated CTR who completed the intake questionnaire was approached on the day of surgery for consent to participate in the study. After obtaining consent but prior to surgery, these patients completed a second questionnaire and then completed a postoperative questionnaire on follow-up at a mean of 8 weeks postoperatively. RESULTS: Thirty-nine patients and 35 patients were included in the retrospective and prospective cohorts, respectively. No significant differences were observed in age, gender, symptom duration, nerve conduction study/electromyography results, or disease severity between the two groups. We identified no statistically significant difference in preoperative or postoperative QuickDASH score between the retrospective and prospective cohorts (39.8 ± 22.7 vs. 39.7 ± 19.1 preoperatively; 27.3 ± 24.7 vs. 18.7 ± 13.3 postoperatively) or within the prospective cohort before and after obtaining informed consent. CONCLUSION: Informed consent did not significantly alter patient responses to the QuickDASH questionnaire. These results suggest that both "opt-in" and "opt-out" approaches to observational research in hand surgery provide results that may be applicable to a generalized orthopedic practice. CLINICAL RELEVANCE: This study provides evidence that will inform the interpretation of observational research findings in hand surgery.

Geriatric Cyclists: Assessing Risks, Safety, and Benefits.

Nearly 1 in every 3 Americans ride bicycles each year, but only 20% of the reported 100 million cyclists ride on a weekly basis. Bicycling is a common form of transportation and recreation and has gained popularity among the elderly patients. In recent years, the number of elderly cyclists has increased steadily and studies have cited ease of use, need for exercise, and enjoyment as important contributing factors. The benefits of physical activity on health is well-documented, and elderly individuals are encouraged to remain active to reduce the progression of age-related weakness and loss of muscle mass. Safety concerns, however, have been a prevalent public health issue. According to the Center for Disease Control and Prevention, elderly and teenage cyclists account for the highest number of head injuries and fatalities among all cyclists. Safety measures that include wearing protective gear such as helmets and choosing the appropriate bicycle have been recommended to minimize the risk of sustaining injuries while riding. Despite these concerns, bicycling has remained a popular and exciting activity for the elderly patients.

Spinal Cord Injury in the Geriatric Population: Risk Factors, Treatment Options, and Long-Term Management.

Spinal cord injuries (SCIs) are sustained by more than 12 500 patients per year in the United States and more globally. The SCIs disproportionately affect the elderly, especially men. Approximately 60% of these injuries are sustained traumatically through falls, but nontraumatic causes including infections, tumors, and medication-related epidural bleeding have also been documented. Preexisting conditions such as ankylosing spondylitis and diffuse idiopathic skeletal hyperostosis can render the spine stiff and are risk factors as well as cervical spondylosis and ensuing cervical stenosis. Treatment options vary depending on the severity, location, and complexity of the injury. Surgical management has been growing in popularity over the years and remains an option as it helps reduce spinal cord compression and alleviate pain. Elevating mean arterial pressures to prevent spinal cord ischemia and avoiding the second hit of SCI have become more common as opposed to high dose steroids. Ongoing clinical trials with pharmacological agents such as minocycline and riluzole have shown early, promising results in their ability to reduce cellular damage and facilitate recovery. Though SCI can be life changing, the available treatment options have aimed to reduce pain and minimize complications and maintain quality of life alongside rehabilitative services.

Initial Preoperative Management of Geriatric Hip Fractures.

Hip fractures are a common emergency among the geriatric population and often requires immediate hospitalization for proper assessment. More than 90% of the time, hip fractures are suffered by individuals older than 65 and are usually precipitated predominantly by falls. Current studies show that the average individual over 65 years falls at least once a year, and roughly 1 out of every 4 of these individuals succumb to their injuries just 12 months following surgical treatment. Moreover, timely treatment and management of these hip fractures have shown to decrease mortality by reducing cardiopulmonary and venous thromboembolic complications that often accompany hip surgeries. As a result, an emphasis on initial preoperative assessment is important to help identify the presence of ancillary factors such as preexisting comorbidities, which can impact the course of treatment. Delaying surgical management of hip fractures has been linked to decreased functional outcomes and increased mortality rates. Time, rather than technique, appears to be a recurring factor that can impact the long-term survival of these patients. The initial preoperative assessment, therefore, presents a window of opportunity where possible interventions can be made in an effort to reduce the delay of surgery, minimize postsurgical complications, and ultimately improve mortality rate among patients with hip fracture.

Distal Radius Fracture Outcomes and Rehabilitation.

Distal radius fractures account for nearly 1 of every 5 fractures in individuals aged 65 or older. Moreover, increased susceptibility to vertebral and hip fractures has been documented in patients a year after suffering a distal radius fracture. Although women are more susceptible to hip fractures, men experience a higher mortality rate in the 7 years following a distal radius fracture. Traditional approaches to distal radius fractures have included both surgical and nonsurgical treatments, with predominant complaints involving weakness, stiffness, and pain. Nonsurgical approaches include immobilization with or without reduction, whereas surgical treatments include dorsal spanning bridge plates, percutaneous pinning, external fixation, and volar plate fixation. The nature of the fracture will determine the best treatment option, and surgeons employ a multifactorial treatment approach that includes the patient's age, nature of injury, joint involvement, and displacement among other factors. Historically, closed reduction and percutaneous pinning have been the most popular approaches. However, volar plate fixation is quickly becoming a popular option as it minimizes tendon irritation, reduces immobilization time, and decreases risk of complication. The goal of treatment is to restore mobility, reduce pain, and improve functional outcomes following rehabilitation. The aim of this review is to summarize the most common treatments and importance of early referral to hand therapy to improve functional outcomes.

The Geriatric Driver: Factors That Influence When to Stop Driving.

The increase in the growth of the elderly population in the past 2 decades has been paralleled by an increase in the number of active elderly drivers. Consequentially, this growth has been accompanied by a rise in fatal road-related accidents. Due to age-related fragility, elderly drivers are more susceptible to injuries and death following a road-related accident. The increased risk of accidents has become a growing public health issue and has led to certain guidelines and restrictions for elderly drivers. Moreover, the cognitive and physiological decline that exacerbates with age has encouraged preventative measures aimed at optimizing their ability to operate motor vehicles. Some of these include yearly vision, cognitive, motor, and mental assessment tests. Results obtained from these tests may help suggest when an elderly driver becomes unsuitable to drive.

Evaluating Problems With Footwear in the Geriatric Population.

Foot pathologies are common in nearly 80% of all elderly patients, and studies have indicated inappropriate footwear as one of the major underlying cause. It has been postulated that ill-fitting shoe wear affects plantar pressure, thus exacerbating weak balance. Complications arising from foot pathologies, which include difficulty in maintaining balance, have increased the risk of falls that can result in fractures and other serious injuries. The link between footwear and the onset or progression of certain foot pathologies has emphasized the need to explore and promote preventative measures to combat the issue. Wider and higher toe boxed shoes, along with sneakers, are examples of footwear documented to evenly distribute plantar pressure, increase comfort, and facilitate appropriate balance and gait. Ultimately, the use of appropriate footwear can help to better stabilize the foot, thus reducing the risk of sustaining debilitating physical injuries known to drastically decrease the quality of life among the geriatric population.
