Orthopedic Surgery Matched Applicants Are Publishing More: A Bibliometric Analysis of Research Output.

Introduction This study analyzed the number of peer-reviewed publications submitted by matriculants prior to applying for the orthopedic surgery residency. The graduating residency classes of 2023 and 2027 were included in the study to understand the trend of publications, to inform aspiring orthopedic surgeons. Methods The top, middle, and bottom 10 orthopedic surgery residency programs were identified on the Doximity online website. Matriculants were searched on PubMed and Google Scholar for publication contributions. Variables including number of publications, orthopedic publications, first-author authorship, and H-index were analyzed. A logistic regression model was created, and a t-test was conducted to statistically compare the 2027 and 2023 graduating classes. Results Matriculants of the 2023 match had higher numbers of publications, orthopedic surgery-specific publications, first authorships, and h-indices than the matriculants of the 2018 match. Conclusion The average number of publications has been observed to increase over four years, indicating an increase in competition to match into orthopedic surgery residency. Publishing in higher numbers may be a good indicator of an applicant's success in not only matching but also matching into a higher-tier program.

The effectiveness of pre-contoured titanium alloy rods in inducing thoracic kyphosis after sequential spinal releases in an in vitro biomechanical model.

Purpose: Evaluate the ability of pre-contoured rods to induce thoracic kyphosis (TK) in human cadaveric spines and determine the effectiveness of sequential surgical adolescent idiopathic scoliosis (AIS) release procedures. Methods: Six thoracolumbar (T3-L2) spine specimens were instrumented with pedicle screws bilaterally (T4-T12). Over correction using pre-contoured rods was performed for intact condition and Cobb angle was measured. Rod radius of curvature (RoC) was measured pre- and post-reduction. The process was repeated following sequential release procedures of (1) interspinous and supraspinous ligaments (ISL); (2) ligamentum flavum; (3) Ponte osteotomy; (4) posterior longitudinal ligament (PLL); and (5) transforaminal discectomy. Cobb measurements determined the effective contribution of release on TK and RoC data displayed effects of reduction to the rods. Results: The intact TK (T4-12) was 38.0° and increased to 51.7° with rod reduction and over correction. Each release resulted in 5°-7°of additional kyphosis; the largest releases were ISL and PLL. All releases resulted in significant increases in kyphosis compared to intact with rod reduction and over correction. Regionally, kyphosis increased ∼2° for each region following successive releases. Comparing RoC before and after reduction showed significant 6° loss in rod curvature independent of release type. Conclusion: Kyphosis increased in the thoracic spine using pre-contoured and over corrected rods. Subsequent posterior releases provided a substantial, meaningful clinical change in the ability to induce additional kyphosis. Regardless of the number of releases, the ability of the rods to induce and over correct kyphosis was reduced following reduction.

Prescribing braces after forearm fractures does not decrease refracture rate.

Refracture is one of the most common complications of pediatric forearm fractures. One way to decrease this risk is to extend immobilization with a brace after the cast has been removed to allow for a range of motion exercises. The purpose of this study was to examine whether prescribing a brace after casting was discontinued decreased the risk of refracture. A retrospective, cohort study was performed at one level I trauma center. Girls under 10 years and boys under 12 years who sustained a forearm fracture from January 2013 to December 2018 were included. Patients with open fractures, fractures that required operative intervention, fractures involving the physis, fracture-dislocations, floating elbows, fractures in children with endocrine abnormalities, and fractures in patients lost to follow-up were excluded. The primary endpoint was a refracture within 6 months of the original injury that extended through the original fracture site. In total 2093 patients met the inclusion criteria. There were 19 refractures (0.9%). There was no statistically significant difference in the refracture rate between the braced (11/1091) and unbraced (8/1002) cohorts (Fisher exact value 0.65 at P < 0.05). The most common fracture type that went on to refracture was greenstick fractures. This large, retrospective study aimed to examine whether prescribing a brace had any significant effect on the refracture rate. Bracing after the cast is removed may help ease family anxiety and extend the period of immobilization while allowing for hygiene and range of motion, but it does not significantly decrease the rate of refracture.

Evaluation of shoulder balance in early onset scoliosis after definitive fusion and comparison with adolescent idiopathic scoliosis shoulder balance.

STUDY DESIGN: The Children Spine Study Group registry was queried for early onset scoliosis (EOS) patients who had final definitive spinal fusion after their scoliosis was managed with either growing rods or VEPTR. The Harms Study Group registry was queried for adolescent idiopathic scoliosis (AIS) patients who had definitive fusion OBJECTIVE: The goal is to assess shoulder alignment in EOS patients after a definitive fusion and how these radiographic outcomes relate to the more familiar situation of post-definitive fusions shoulder alignment in AIS patients. BACKGROUND: EOS is a challenging pathology to manage. Numerous components are important in the success of spinal surgery for this population. Shoulder balance is a one of the components that is easily seen by the patient. Recently, the importance of its relationship to patient satisfaction has received greater attention. METHODS: Sample size: n = 145 (EOS (n = 34) and AIS (n = 111)). Shoulder balance parameters (SBP) of clavicular angle (CA), coracoid height difference (CHD), clavicular tilt angle difference (CTAD), and clavicle-rib cage intersection difference (CRID) measurements were measured from the reviewed radiographs and documented pre-definitive, post-definitive and 2-year follow-up measures. Shoulder balance parameters were compared between EOS and AIS cohorts at documented intervals. RESULTS: EOS mean pre-definitive fusion SBPs (CA, CTAD, CRID, CHD) were significantly higher compared to AIS, p = 0.004, 0.003, < 0.001, < 0.001, respectively. Significant post-definitive fusion corrections were noticed for CTAD (0.01), CHD (0.01), nearly significant CA (0.07), non-significant CRID in EOS patients. In AIS patients, no significant corrections were noticed for CA, CTAD, CHD and but significant for CRID (0.02). At post-definitive and 2-year follow-up, CA, CRID, CHD were not significant between cohorts, but CTAD (< 0.01) was significantly higher in EOS cohort at final follow-up. CONCLUSION: Post-definitive and 2-year follow-up shoulder balance for EOS patients was not significantly different from AIS patients. LEVEL OF EVIDENCE: III.

Electronic Medical Record Use and Satisfaction Among Pediatric Orthopaedic Surgeons.

INTRODUCTION: Electronic medical record (EMR) use among pediatric orthopaedic surgeons has evolved substantially within the past decade. In response to the Patient Protection and Affordable Care Act, large hospitals and tertiary pediatric medical centers rapidly acquired and implemented EMRs with uncertainty as to the potential impact on patient care and operational efficiency of subspecialists. This study reviews the background and regulatory framework for Meaningful Use of EMR and assesses the current landscape of EMR utilization by pediatric orthopaedic surgeons. METHODS: In 2015, the Practice Management Committee distributed a survey regarding EMR use and satisfaction to members of the Pediatric Orthopaedic Society of North America. Survey responses from 324 members were used to analyze levels of satisfaction by EMR platform and practice type and to consider drivers of satisfaction or dissatisfaction of end users. RESULTS: Although there were no differences in overall satisfaction based on vendor or practice type, significant differences were noted for 5 specific parameters of satisfaction, including: usefulness of templates, efficiency of practice workflow, information services support, number of logon events, and speed of the system. A user/vendor map is provided to facilitate networking among providers and groups utilizing common EMR platforms to help bring about rational improvements in EMR functionality for the future. CONCLUSIONS: Substantial effort needs to be made to improve subspecialty-specific EMR documentation, order entry, research tools, and clinical workflows to enhance the processes of care for children with orthopaedic conditions in the era of EMR.

Pediatric Sports Medicine, A New Subspeciality in Orthopedics: An Analysis of the Surgical Volume of Candidates for the American Board of Orthopaedic Surgery Part II Certification Exam Over the Past Decade.

BACKGROUND: Pediatric orthopaedic surgery has become increasingly subspecialized over the past decade. The purpose of this study was to analyze the volume of pediatric sports medicine cases performed by surgeons applying for the American Board of Orthopaedic Surgeons (ABOS) Part II certification exam over the past decade, comparing caseloads according to the type(s) of fellowship completed. METHODS: The ABOS database was reviewed for all surgeons applying for the ABOS Part II certification exam from 2004 to 2014. Fellowship training of the candidates was recorded as Pediatrics, Sports, and Dual-Fellowship (fellowship in both Pediatrics and Sports). All other candidates were categorized as "Other". A total of 102,424 pediatric cases (patients below 18 years) were reviewed to identify sports medicine cases performed by CPT code. Multiple linear regression and Mann-Whitney U tests were used to determine trends in case volume overall and according to fellowship training for all patients, patients ≥13 and patients <13. One-way ANOVA testing was used to compare multiple means followed by multiple post hoc comparisons using a Tukey all pairwise approach using SPSS. RESULTS: A total of 14,636 pediatric sports medicine cases were performed. There was an increase in the number of sports medicine cases performed in patients <13 (117.5±31.8 from 2004-2009 to 212.4±70.1 from 2010-2014, P=0.035; r=0.743, P=0.0007). The number of Pediatrics (r=0.601, P=0.005), Sports (r=0.741, P=0.0007) and Dual-Fellowship candidates increased (r=0.600, P=0.005) from 2004-2014. Dual-Fellowship surgeons performed 21.4% of pediatric sports medicine cases in 2014 when compared to 2.1% in 2004 (919% increase). As a group, the number of pediatric sports cases performed by Dual-Fellowship (r=0.630, P=0.004) and Sports (r=0.567, P=0.007) candidates has increased, while the number performed by "Other" candidates has decreased (r=0.758, P=0.0005). Per surgeon, Dual-Fellowship candidates performed a greater number of pediatric sports cases per collection period (36.5±9.18) than Pediatrics (6.71±0.94), Sports (5.99±0.46), and "Other" (1.21±0.15, P<0.0001 for each) candidates from 2004 to 2014. CONCLUSIONS: Over the past decade operative sports injuries have increased in children with a similar increase in the number of orthopedic surgeons specializing in pediatric sports medicine. On a per surgeon basis, these dual fellowship-trained candidates have performed on average five times the number of pediatric sports medicine cases compared to all other ABOS Part II candidates. These trends may point towards the development of a new subspecialty of pediatric sports medicine among orthopedic surgeons. LEVEL OF EVIDENCE: Level IV-Retrospective Database Review.

Changes in the Practice of Pediatric Orthopaedic Surgeons Over the Past Decade: Analysis of the Database of the American Board of Orthopaedic Surgery.

BACKGROUND: There has been an increase in the number of the graduates of pediatric orthopaedic fellowship programs over the past decade creating the potential for increased competition in the field. The purpose of this study was to analyze the effect of increased number of pediatric orthopaedic fellowship graduates on case volume as well as the type of procedures performed by recent graduates of pediatric orthopaedic fellowship programs from 2004 to 2014. METHODS: Case logs submitted for the American Board of Orthopaedic Surgery Part II examination by applicants with the self-declared subspecialty of pediatric orthopaedics from 2004 to 2014 were analyzed. Cases were categorized as trauma (upper and lower extremity), spine, sports medicine, hip, deformity correction, foot and ankle, hardware removal, soft tissue procedures, and other. The period was divided into 3 sections: 2004-2007, 2008-2011, 2012-2014. Descriptive analysis was used to report the change in the volume and pattern of practices over the study period. RESULTS: Although the number of pediatric orthopaedic subspecialty applicants increased from 15 to 44 from 2004 to 2014, the average cases per year increased from 2142 in 2004-2007 to 2960 in 2007-2011, and to 4160 in 2012-2014. The number of cases performed per applicant remained stable over the study period. Upper extremity trauma cases were the largest category of cases reported and increased in case volume by 141% from 2004 to 2014. Sports medicine cases increased in volume by 175%. CONCLUSIONS: Despite a large increase in the number of pediatric orthopaedic surgeons over the past decade, there is a concomitant increased in case volume across almost all subspecialties within pediatric orthopaedics. As such, pediatric orthopaedic surgeons who start a new practice can expect to develop a robust practice with a diverse group of pathologies. LEVEL OF EVIDENCE: Level III.

The Pursuit of Scholarship: Why We Should Care About Resident Research.

Research is a foundational component of an orthopaedic residency. It fosters intellectual curiosity and pursuit of excellence, while teaching discipline and the scientific method. These are the key principles for careers in both community-based practice and academia. Currently, no consensus exists on how to best engage residents and support their research endeavors. In 2014, the American Academy of Orthopaedic Surgeons Board of Specialty Societies Research and Quality Committee convened a Clinician-Scientist Collaboration Workgroup. The workgroup's task was to identify barriers to clinical and basic science research, and to propose feasible recommendations to overcome these barriers. Herein, we have compiled the opinions of various stakeholder constituencies on how to foster scholarly pursuits during an orthopaedic residency. These opinions reflect the workgroup's conclusions that research is directly and indirectly influenced by funding, departmental support, and mentorship, and that early exposure and dedicated time to pursue scholarly activities may have a positive impact on lifelong research interests.

Effect of Pedicle Fill on Axial Pullout Strength in Spinal Fixation After Rod Reduction.

Rod reduction to pedicle screws is used for a variety of spinal fixation procedures; however, it can alter the integrity of the screw-bone interface. The authors investigated the effect of pedicle fill (ratio of pedicle screw diameter to pedicle diameter) on the strength of the screw-bone interface after simulated rod reduction on 17 vertebrae (3 thoracolumbar spine specimens). Pedicle diameter was measured with standard clinical computed tomography scan protocols. The authors determined the minimum pedicle diameter for each level. Polyaxial pedicle screws were surgically placed bilaterally with a freehand technique with standard clinical anatomic landmarks. The pedicle pairs were instrumented with pedicle screws of predetermined diameter, 1 with greater than 80% fill and 1 with less than 80% fill. A simulated reduction maneuver was performed with a 5-mm gap followed by an axial pullout test to assess screw interface strength. Comparison of insertion torque between less than 80% fill and greater than 80% fill did not show significant increases. A significant difference in pullout load (P=.043) occurred with greater than 80% fill (791±637 N) compared with less than 80% fill (636±492 N). No significant difference in stiffness was noted (P=.154) with pedicle fill of greater than 80% (427±134 N/mm) compared with less than 80% (376±178 N/mm). The current findings support the use of greater than 80% pedicle fill for optimal screw anchoring in pedicle screw-based constructs involving rod reduction. Surgeons should consider placing screws that can safely fill vertebral pedicles, especially at the apex of the curve and the proximal and distal levels of constructs, where excessive forces are imparted to the screws.

Chronic C1-C2 Rotatory Subluxation Reduced by C1 Lateral Mass Screws and C2 Translaminar Screws: A Case Report.

BACKGROUND: C1-C2 rotatory subluxation can result from a variety or etiologies. Pediatric patients are particularly susceptible to C1-C2 rotatory subluxation. If left untreated the condition is termed an atlantoaxial rotatory fixation (AARF) and chronic neck pain and deformity can result. Patients failing conservative treatment or those with recurrent or chronic rotatory subluxation may require halo treatment or surgical intervention. This illustrative case report is about a patient with chronic C1-C2 AARF who was treated with C1 lateral mass screws and C2 translaminar screws, a treatment that has not been addressed by this technique in a pediatric population. METHODS: This is a retrospective case review. RESULTS: After an unsuccessful attempt at reduction, an 11-year-old girl underwent surgery to treat her C1-C2 AARF. Through an all posterior approach, screws were placed bilaterally into the C1 lateral masses followed by the placement of C2 translaminar screws bilaterally. A small amount of distraction was applied through the screw construct to open up the C1-C2 articulation and the AARF was open reduced and fused. A detailed postoperative computed tomographic scan focused on the occiput C1-C2 joint confirmed the anatomical reduction of the joint complex. CONCLUSIONS: The patient had cosmetically pleasing relief of her torticollis and was doing well at 60 months after surgery. LEVEL OF EVIDENCE: Level IV.

Are Traditional Radiographic Methods Accurate Predictors of Pedicle Morphology?

STUDY DESIGN: Cadaveric in vitro computed tomography (CT) imaging study. OBJECTIVE: To examine minimum pedicle diameter from transverse and coronal CT reconstructions of thoracolumbar spine specimens and compare their degree of disparity, if any. Pedicle angulation in coronal and transverse planes was measured and their contribution to the disparity in minimum pedicle diameter was assessed. SUMMARY OF BACKGROUND DATA: Spinal minimum pedicle diameter can be obtained from both transverse and coronal CT reconstructions; however, the degree of disparity in these measurements has not been described previously. Angulation of the pedicle in transverse and coronal planes may contribute to a disparity in minimum pedicle diameter acquired from reconstructions. This also has not been described previously. This study examined whether the disparity could be predicted by spinal level, as pedicle angulations vary in both coronal and transverse planes. METHODS: Five thoracolumbar specimens (T1-L5, age 48-59 yrs, male) were CT scanned utilizing clinical protocols. Minimum pedicle diameters and pedicle angulations were acquired in transverse and coronal reconstructions. Disparities between minimum pedicle diameters were measured and the correlation between this disparity and spinal level was characterized. RESULTS: A significant difference (P < 0.001) in minimum pedicle diameter existed between measures from coronal and transverse reconstructions. There was a significant correlation (P < 0.001) between the difference in minimal pedicle diameter and the transverse pedicle angle as well as the coronal pedicle angle. CONCLUSION: An overestimation of minimum pedicle diameter in the transverse reconstruction occurs when the coronal pedicle angulation increases, and in the coronal reconstruction when the transverse pedicle angulation increases. Therefore, pedicle angle should be determined using both coronal and transverse reconstructions and utilized to reduce the risk of overestimation of the true pedicle diameter. LEVEL OF EVIDENCE: NA.

Fifteen to twenty-five year functional outcomes of twenty-two patients treated with posterior Cotrel-Dubousset type instrumentation: a limited but detailed review of outcomes.

BACKGROUND: Long-term outcomes of patients undergoing extensive fusions for adolescent idiopathic scoliosis (AIS) have conflicting results. Moskowitz found uninstrumented scoliosis fusion patients had similar back pain as a normal age matched population. Recently, long-term outcomes of patients with Harrington rod instrumentation were reviewed and found similar functional outcome scores to non-scoliosis patients, with trending toward worse outcomes when fusions extended to L4. Our study examined long-term functional outcomes of patients treated with Cotrel-Dubousset (CD) instrumentation and determined whether distal level of instrumented fusion (L4 and L5) correlate with increased back pain or lower functional level. METHODS: Retrospective review of AIS surgeries from 1986 to 1996 was undertaken. Patient demographics and surgical data were collected via case-note audit. Patients were contacted and asked to complete a series of functional outcome questionnaires including visual analog scales (VAS) for pain, Short-Form 36 (SF-36), Scoliosis Research Society 22 (SRS-22) and Oswestry Disability Index (ODI) for function. ANOVA technique categorically compared outcome scores to most distal levels of fusion. Linear regression compared patient reported outcomes to time elapsed since surgery. Statistical significance was p < 0.05. RESULTS: One hundred twelve patients were identified, 50 patients were contacted, and 22 agreed to participation and completed a full assessment. Follow-up time since surgery ranged from 15 to 26 years and age ranged from 30 to 43 years. Six patients reported daily VAS back pain of ≥5; with a mean of 2.5. Back pain was not associated with level of distal fusion (p = 0.92). ODI was 15.36, with six patients' ODI >20. No relationship was shown between ODI and distal level of fusion (p = 0.72). SF-36 and SRS 22 values were also not related to distal level of instrumentation. Patient reported VAS back pain scores (r(2) = 0.18, p = 0.05), ODI (r(2) = 0.09, p = 0.17), and SF-36 and SRS-22 were not worse in patients with longer follow-up over time. Back pain and certain functional score subcategories of the SF-36 and SRS-22 trended toward improved results over time. CONCLUSIONS: Most patients who underwent multi-segment spinal fixation appeared to do well long-term, with minimal back pain. Lowest instrumented segment did not appear to be associated with increased back pain after 15 to 25 years follow-up.

Patient satisfaction surveys: an evaluation of POSNA members' knowledge and experience.

BACKGROUND: Patient satisfaction surveys (PSS) were originally designed to identify areas in need of improvement in patient interactions for individuals, practices, and institutions. As a result of the Affordable Care Act, the Centers for Medicare and Medicaid Services incorporated PSS into a formula designed to determine the quality of medical care delivered to hospital inpatients; the resultant score and rank will determine subsequent hospital payments. This survey was developed to evaluate POSNA members' knowledge of and experience with PSS. METHODS: The POSNA Practice Management Committee developed a 14-question survey that was sent to all active and candidate members (850). A total of 229 members responded; and results were tabulated by answer and simple percentages were calculated for each question. Comments were reviewed and grouped by similarity to identify frequency. RESULTS: A total of 82% of respondents were aware of PSS with 67% stating they were utilized in their setting. Utilization of PSS rarely alters clinical decision making. However, PSS do affect decisions regarding the patient experience; and 45% of respondents believe that PSS have utility with respect to business decisions. Fifty-nine percent of respondents feel that scores can be predictably improved. Less than half the respondents stated that they had a good or excellent understanding of PSS and only 48% believe that PSS are a valid measure of health care quality. CONCLUSIONS: POSNA members' knowledge of and experience with PSS are not universal or uniform. Although most agree that patient satisfaction does not drive clinical decision making, it does appear to impact business and clinic-flow decisions with the idea that it can be predictably improved. Despite this, members' self-assessed that knowledge is average and it is not clear to the members that patient satisfaction reflects medical quality. On the basis of these findings and as the impacts of PSS become more prominent, efforts to educate the members of POSNA about PSS should be enhanced. Furthermore, research to identify and develop best practices that enhance patient satisfaction and well-being while minimizing costs should be supported. LEVEL OF EVIDENCE: Level IV.

Toward a better understanding of direct vertebral rotation for AIS surgery: development of a multisegmental biomechanical model and factors affecting correction.

BACKGROUND CONTEXT: The direct vertebral rotation (DVR) technique involves vertebral manipulation by the application of force in the transverse plane using a pedicle screw as the anchor point. The biomechanics of this technique has not been well studied, and the applied derotation force may affect cosmetic outcome and potential complications. PURPOSE: The purpose of the study was to develop an in vitro biomechanical model replicating DVR and examine the effects of screw placement, derotation direction, and segmental versus en bloc rotation on correction. STUDY DESIGN: This study is based on a cadaveric spine model examining the biomechanics of DVR. METHODS: Short three vertebral segments were dissected from thoracolumbar cadaveric spines (T5-L4). Each pedicle of the central vertebra received a unicortical, bicortical, or in-out-in screw. Unconstrained biomechanical tests were performed in an axial rotation (medial and lateral directions) mimicking DVR surgery. Nondestructive tests were performed examining peak force and rotational stiffness with/without a contralateral rod. A destructive failure test was performed on each pedicle screw with a contralateral rod connecting via the contralateral pedicle screw. Repeated-measures analysis of variance and post hoc Student t tests were used to detect significance with screw placement and loading direction as main factors. RESULTS: Without the contralateral rod, the rotation direction was significant (p=.004, medial stiffness more than lateral). With the contralateral rod, in-out-in placement demonstrated lower stiffness than unicortical or bicortical screws (p=.009), and the rotation direction was significant (p=.003, medial stiffness more than lateral). There was no interaction effect between main factors. Peak force with and without a contralateral rod resulted in a similar pattern of significance as stiffness. Destructive failure tests showed that the placement was significant (p<.02) with in-out-in resulting in lower stiffness than unicortical- and bicortical-placed screws. In-out-in (25±6 N) and unicortical (35±16 N) placements resulted in lower peak load (p<.001) than bicortical (48±17 N) screws. CONCLUSIONS: The biomechanical characteristics of DVR are dependent on the derotation direction and screw placement. Correction for adolescent idiopathic scoliosis can be attempted irrespective of the type of pedicle screw placement, more efficiently if performing derotation maneuvers en bloc on bicortical screws in the medial direction.

Pediatric disk herniation.

Pediatric disk herniation is a rare condition that should be considered in the differential diagnosis of the child with back pain or radiating leg pain. Because pediatric disk herniation is relatively uncommon, there is typically a delay in diagnosis compared with time to diagnosis of adult disk herniation. Pediatric disk herniations are often recalcitrant to nonsurgical care, but such measures should be attempted in patients who present with isolated pain symptoms and have a normal neurologic examination. Twenty-eight percent of adolescent disk herniations involve apophyseal fractures; this presentation has a higher rate of surgical intervention than do herniations without fracture. Surgical management of pediatric disk herniation involves laminotomy and fragment excision. Short-term data demonstrate excellent pain relief, with 1% of children requiring repeat surgery for lumbar disk pathology in the first year. Long-term data suggest that 20% to 30% of patients will require additional surgery later in life.

Medical errors in orthopaedics. Results of an AAOS member survey.

BACKGROUND: There has been widespread interest in medical errors since the publication of To Err Is Human: Building a Safer Health System by the Institute of Medicine in 2000. The Patient Safety Committee of the American Academy of Orthopaedic Surgeons has compiled the results of a member survey to identify trends in orthopaedic errors that would help to direct quality assurance efforts. METHODS: Surveys were sent to 5540 Academy fellows, and 917 were returned (a response rate of 16.6%), with 53% (483) reporting an observed medical error in the previous six months. RESULTS: A general classification of errors showed equipment (29%) and communication (24.7%) errors with the highest frequency. Medication errors (9.7%) and wrong-site surgery (5.6%) represented serious potential patient harm. Two deaths were reported, and both involved narcotic administration errors. By location, 78% of errors occurred in the hospital (54% in the surgery suite and 10% in the patient room or floor). The reporting orthopaedic surgeon was involved in 60% of the errors; a nurse, in 37%; another orthopaedic surgeon, in 19%; other physicians, in 16%; and house staff, in 13%. Wrong-site surgeries involved the wrong side (59%); another wrong site, e.g., the wrong digit on the correct side (23%); the wrong procedure (14%); or the wrong patient (5% of the time). The most frequent anatomic locations were the knee and the fingers and/or hand (35% for each), the foot and/or ankle (15%), followed by the distal end of the femur (10%) and the spine (5%). CONCLUSIONS: Medical errors continue to occur and therefore represent a threat to patient safety. Quality assurance efforts and more refined research can be addressed toward areas with higher error occurrence (equipment and communication) and high risk (medication and wrong-site surgery).

Slipped capital femoral epiphysis in down syndrome.

Slipped capital femoral epiphysis (SCFE) and Down syndrome are both uncommon in the population at large, and rarely are both conditions present in a single individual. Institutional records were searched for both Down syndrome and SCFE. At least 2 years of follow-up was required. Eight patients were identified. At presentation four patients could not walk due to pain and four could walk. Six of eight hips presented with grade III SCFE. Four hips were treated with internal fixation in situ and four were manipulatively reduced in the operating room at the time of fixation with percutaneous screws or pins. Three hips healed uneventfully. Five hips developed aseptic necrosis (three partial, two whole head). This small retrospective study suggests an extremely high rate of complications in adolescents with Down syndrome and SCFE.

Pulsed color-flow Doppler analysis of arterial deficiency in idiopathic clubfoot.

This prospective study used pulsed color-flow Doppler sonography to determine differences in the presence and direction of flow through the dorsalis pedis, posterior tibial, and peroneal arteries in a group of children with clubfoot and a comparison group of controls. There was a statistically significant difference in the prevalence of deficient (absent or retrograde flow) dorsalis pedis arteries in children with clubfoot (45%) compared with controls (8%). This indicates that there is an association between some clubfeet and deficiency of the dorsalis pedis artery. There was a trend toward difference in the prevalence of deficiency of the dorsalis pedis artery in the clubfeet that required surgery (54%) compared with those that did not (20%), suggesting that dorsalis pedis artery deficiency may be more prevalent among clubfeet with greater deformity.
