Orthopaedic resident and program director opinions of resident duty hours: a national survey.

BACKGROUND The Accreditation Council for Graduate Medical Education (ACGME) established national guidelines for resident duty hours in July 2003. Following an Institute of Medicine report in December 2008, the ACGME recommended further restrictions on resident duty hours that went into effect in July 2011. We conducted a national survey to assess the opinions of orthopaedic residents and of directors of residency and fellowship programs in the U.S. regarding the 2003 and 2011 ACGME resident duty-hour regulations and the effects of these regulations on resident education and patient care. METHODS A fifteen-item questionnaire was electronically distributed by the Candidate, Resident, and Fellow Committee of the American Academy of Orthopaedic Surgeons (AAOS) to all U.S. orthopaedic residents (n = 3860) and directors of residency programs (n = 184) and fellowship programs (n = 496) between January and April 2011. Thirty-four percent (1314) of the residents and 27% (185) of the program directors completed the questionnaire. Statistical analyses were performed to detect differences between the responses of residents and program directors and between the responses of junior and senior residents. RESULTS The responses of orthopaedic residents and program directors differed significantly (p < 0.001) for fourteen of the fifteen survey items. The responses of residents and program directors were divergent for questions regarding the 2003 rules. Overall, 71% of residents thought that the eighty-hour work week was appropriate, whereas only 38% of program directors agreed (p < 0.001). Most program directors (70%) did not think that the 2003 duty-hour rules had improved patient care, whereas only 24% of residents responded in the same way (p < 0.001). The responses of residents and program directors to questions regarding the 2011 duty-hour rules were generally compatible, but the degree to which they perceived the issues was different. Only 18% of residents and 19% of program directors thought that the suggested strategic five-hour evening rest period implemented in July 2011 for on-call residents was appropriate (p > 0.05), and both groups (84% of residents and 74% of program directors) also disagreed with the limitation of intern shifts to sixteen hours (p < 0.001). Seventy percent of residents and 79% of program directors thought that the new duty-hour regulations would result in an increased number of handoffs that would be detrimental to patient care (p < 0.001). The mean responses of junior residents and senior residents differed for eight of the fifteen survey items (p < 0.001), with the responses of senior residents more closely resembling those of program directors on six of these eight questions. The mean responses and percentiles for the survey items did not differ significantly between residency directors and fellowship directors (p > 0.05). CONCLUSIONS This national survey indicated significant differences between the opinions of orthopaedic residents and program (residency and fellowship) directors regarding the 2003 ACGME resident duty-hour regulations and the effects of these regulations on resident education and patient care. However, both residents and program directors agreed that the further reductions in duty hours in the 2011 rules may be detrimental to resident education and patient care.

Health literacy in an orthopedic trauma patient population: A cross-sectional survey of patient comprehension

Objectives: The aim of this study was to evaluate the level of comprehension in an orthopedic trauma patient population regarding injury, surgery, and postoperative instructions and to determine if educational background is associated with inadequate comprehension. Design: This involved a prospective observational cohort. Setting: The study was conducted at an Academic Level 1 trauma center. Patients: From April to June 2011, 248 orthopedic trauma patients with an operatively fixed isolated fracture were found to be eligible for inclusion. One hundred forty-six eligible questionnaires were collected (58.9% response rate). Intervention: The patients were administered a questionnaire during their first postoperative visit before being seen by a physician. The questionnaire included demographic information and questions regarding (1) which bone was fractured; (2) the type of implanted fixation; (3) weight-bearing status; (4) expected recovery time; and (5) need for deep vein thrombosis (DVT) prophylaxis. Multivariable logistic regression analyses were used to examine the association between educational level and questions regarding surgical procedure and discharge instructions. Results: The overall mean score of all the patients on the patient comprehension portion was 2.54 ± 1.27 correct responses out of 5. Only 47.9% of patients knew the bone they fractured, and 18.5% knew their expected healing time. Of the patients, 66.4% knew the type of implanted fixation, and 45.2% knew their weight-bearing status. The patients (74.0%) knew their DVT prophylaxis medication(s). The mean score for patients in the group ⩽ HS (high-school education or less) was 2.26, whereas the mean score for patients in the group > HS (more than high-school education) was 3.00 (P = 0.0009). The patients in the group > HS were 2.54 times more likely to know the bone they fractured (P = 0.01), 3.82 times more likely to know the recovery time (P = 0.004), and 2.79 times more likely to know their DVT prophylaxis medication(s) than patients in the group ⩽ HS. Conclusions: Orthopedic trauma patients demonstrated limited comprehension of their injuries, surgeries, and postoperative instructions. Patients with lower educational levels did significantly worse on the questionnaire than those with higher educational levels. The results of the study highlight a lack of comprehension within this patient population and suggest that an increased focus on patient communication by orthopedic providers may be necessary. Level of Evidence: Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.

Avoidance of Malreduction of Proximal Femoral Shaft Fractures With the Use of a Minimally Invasive Nail Insertion Technique (minit)

Objectives: To determine our rate of malalignment in proximal femoral shaft fractures treated with intramedullary (IM) nails, with and without the use of a minimally invasive nail insertion technique (MINIT). Design: Retrospective study. Setting: Level 1 trauma center. Methods: Between July 1, 2003, and June 31, 2005, 100 consecutive proximal femoral shaft fractures (97 patients) were treated with IM nails. The average age of the 56 men and 41 women was 43.5 years (range, 17 to 96 years). There were 92 closed fractures and 8 open fractures. Fractures were classified according to the Russell-Taylor classification (69 type 1A, 11 type 1B, 3 type 2A, 17 type 2B). All patients underwent antegrade IM nailing using a fracture table in the supine (83) or lateral (17) position. A total of 72 entry portals were trochanteric, and 28 were piriformis. Seventy-seven percent of the femurs were opened with MINIT, a technique that uses a percutaneous cannulated channel reamer over a guide pin as opposed to the standard method of Kuntscher, which employs a femoral awl. Nails were locked proximally using standard locking in 37 fractures, and recon mode in 63. Fracture reduction was examined on immediate postoperative films to determine angulation in the coronal and sagittal planes. Criteria for acceptable reduction were less than 5 degrees angulation in any plane. In addition, surgical position, entry portal, mechanism of injury, Russell-Taylor classification, OTA classification, open or closed fracture, open or closed reduction, and type of implant used were analyzed for significance. Results: The frequency of malalignment was 10% for the entire group of patients. Malalignment occurred in 26% of fractures treated without the use of the MINIT and in 5.2% when the MINIT was used (P < 0.01). There was no statistically significant difference between the different Russell-Taylor fracture types, although there was a trend towards more malalignment in type 2A and 2B fractures (P = 0.06). None of the other factors studied had a statistically significant effect on malalignment. A whole-model test of the factors that were surgeon-controlled (use of the MINIT, surgical position, open or closed reduction, type of implant used, and entry portal) found that only use of the MINIT had a statistically significant effect on malalignment (P < 0.01). Conclusions: The results indicate that use of the minimally invasive nail insertion technique (MINIT) significantly decreases the occurrence of malalignment in proximal femoral shaft fractures.

Stress hyperglycemia and surgical site infection in stable nondiabetic adults with orthopedic injuries

BACKGROUND Hyperglycemia in nondiabetic patients outside the intensive care unit is not well defined. We evaluated the relationship of hyperglycemia and surgical site infection (SSI) in stable nondiabetic patients with orthopedic injuries. METHODS We conducted a prospective observational cohort study at a single academic Level 1 trauma center over 9 months (Level II evidence for therapeutic/care management). We included patients 18 years or older with operative orthopedic injuries and excluded patients with diabetes, corticosteroid use, multisystem injuries, or critical illness. Demographics, medical comorbidities (American Society of Anesthesiologists class), body mass index, open fractures, and number of operations were recorded. Fingerstick glucose values were obtained twice daily. Hyperglycemia was defined as a fasting glucose value greater than or equal to 125 mg/dL or a random value greater than or equal to 200 mg/dL on more than one occasion before the diagnosis of SSI. Glycosylated hemoglobin level was obtained from hyperglycemic patients; those with glycosylated hemoglobin level of 6.0 or greater were considered occult diabetic patients and were excluded. SSI was defined by a positive intraoperative culture at reoperation within 30 days of the index case. RESULTS We enrolled 171 patients. Of these 171, 40 (23.4%) were hyperglycemic; 7 of them were excluded for occult diabetes. Of the 164 remaining patients, 33 were hyperglycemic (20.1%), 50 had open fractures (6 Type I, 22 Type II, 22 Type III), and 12 (7.3%) had SSI. Hyperglycemic patients were more likely to develop SSI (7 of 33 [21.2%] vs. 5 of 131 [3.8%], p = 0.003). Open fractures were associated with SSI (7 of 50 [14%] vs. 5 of 114 [4.4%], p = 0.047) but not hyperglycemia (10 of 50 [20.0%] vs. 23 of 114 [20.2%], p = 0.98). There was no significant difference between infected and noninfected patients in terms of age, sex, race, American Society of Anesthesiologists class, obesity (body mass index > 29), tobacco use, or number of operations. CONCLUSION Stress hyperglycemia was associated with SSI in this prospective observational cohort of stable nondiabetic patients with orthopedic injuries. Further prospective randomized studies are necessary to identify optimal treatment of hyperglycemia in the noncritically ill trauma population. LEVEL OF EVIDENCE Therapeutic study, level III.

Fracture morphology of high shear angle "vertical" femoral neck fractures in young adult patients.

Objective: Management of vertical femoral neck fractures in young adults has been a challenging clinical problem, resulting in mixed clinical outcomes. A thorough understanding of the fracture morphology for this injury pattern is lacking, which may contribute to frequent failures of treatment. This study is designed to produce a detailed description of the pathoanatomy of these fractures, which may ultimately be helpful in developing more informed reduction and fixation strategies. Design: Retrospective study of patient records, plain radiographs, and computed tomography scans to determine the morphology the Pauwels III femoral neck fractures (coronal angle >50 degrees) in young adults. Setting: Two level I and 1 level II regional trauma centers. Patients: All patients 18–49 years of age with a surgically repaired, high-energy high shear angle (>50 degrees) femoral neck fracture from January 1, 2007, to December 31, 2010. Methods: One hundred thirty-six adult patients younger than 50 years were identified with a femoral neck fracture in the study period, of whom 33 met all study criteria. We evaluated plain radiography and computed tomography data including fracture orientation, comminution, deformity, characteristics of the inferomedial fracture spike, and the associated inferomedial calcars cortical buttress. Results: The vertical (coronal) fracture averaged 60 degrees and axial fracture obliquity averaged 24 degrees with relative deficiency of the posterior neck on the head–neck fragment. Major femoral neck comminution (>1.5 cm in any dimension) was identified in 96% of cases, mostly located in the inferior (94%) and posterior (82%) quadrants. The apical fracture spike of the head segment was found to be in line (within 10 degrees) of the neck–shaft axis on the proximal femur 63% of the time. Deformity in external rotation averaged 44 degrees (range, 10–68 degrees) and shortening of the femur averaged 1.8 cm (range, 0.9–4.4 cm). Conclusions: This study investigated the fracture morphology of isolated, high shear angle femoral neck fractures in young adults, which may ultimately lead to improved operative reduction and fixation tactics. Given this injurys characteristic findings, including fracture orientation, deformity, and comminution, surgeons should be cognizant of this patterns innate instability and potential for treatment failure with typical implant constructs.

Health literacy in an orthopaedic trauma patient population: Improving patient comprehension with informational intervention

Objectives: This study aims to evaluate the change in comprehension of diagnoses, treatment plans, and discharge instructions after orthopaedic trauma patients are given an informational document that includes pictorial representations at the time of discharge. It also seeks to determine if the intervention has a greater impact on patients with lower educational backgrounds. Design: Prospective comparative cohort study. Setting: Academic level 1 trauma center. Patients: From April to December 2011, 529 orthopaedic trauma patients with an operatively fixed isolated fracture were eligible for inclusion. Two hundred ninety-nine eligible questionnaires were collected (56.5% response rate). Intervention: Patients were administered a questionnaire regarding their treatment and discharge instructions during their first postoperative clinic visit before being seen by a physician. The questionnaire included demographic information and questions regarding: (1) which bone was fractured, (2) type of implanted fixation, (3) weight-bearing status, (4) expected recovery time, and (5) need for deep vein thrombosis prophylaxis. All patients had received verbal instructions outlining this information at postoperative hospital discharge. During the second half of the study, patients were given an additional informational sheet with both text and pictorial representations at discharge. Multivariable log-binomial regression analyses were used to examine the impact of this intervention. Results: One hundred forty-six patients were given only the standard discharge instructions, whereas 153 patients were also administered the additional information document. The mean score for patients who received the intervention was 2.90 (out of 5) compared with the mean score of 2.54 for patients who did not receive the intervention (P = 0.013). Patients who received the intervention were 1.3 times more likely to know which bone was fractured (P = 0.007) and 1.1 times more likely to be able to correctly name the medication(s) they were prescribed for deep vein thrombosis prophylaxis (P = 0.03). Conclusions: Overall performance on comprehension questionnaires in orthopaedic trauma patients was significantly improved via a text and pictorial intervention. The intervention did not preferentially aid patients with lower education backgrounds. Future studies should evaluate long-term postoperative results to determine if improved patient comprehension has an effect on surgical outcomes and patient satisfaction.

Analysis of single-incision versus dual-incision fasciotomy for tibial fractures with acute compartment syndrome.

Objectives: To analyze the rate of postoperative infection and nonunion after tibial fractures in patients treated for acute compartment syndrome (ACS) using (1) single-incision versus (2) dual-incision fasciotomy technique. Design: Retrospective. Setting: Level I trauma center. Patients: Review of all adult tibial fractures operatively treated (n = 2756) over a 12-year period identified 175 patients with concurrent ACS requiring fasciotomy. Of 60 patients treated with intramedullary nails, 36 patients had single-incision fasciotomy and 24 had dual-incision fasciotomy. Of 81 patients treated with plate fixation, 59 patients had single-incision fasciotomy and 22 had dual-incision fasciotomy. Intervention: Tibial fixation with fasciotomy for ACS. Main Outcome Measurements: Occurrence of postoperative infection and nonunion. Results: Both fasciotomy groups were similar across recorded patient and treatment characteristics. Need for skin graft was similar between fasciotomy groups. For patients treated with intramedullary nail (n = 60), 1 infection (2.8%) occurred in single-incision group versus 2 (8.3%) in dual-incision group (P = 0.558). Seven nonunions (19.4%) occurred in single-incision group versus 3 (12.5%) in dual-incision group (P = 0.726). For plate fixation patients (n = 81), 15 infections (25.4%) occurred with single-incision fasciotomy versus 5 infections (22.7%) with dual-incision fasciotomy (P = 1.000). Seven nonunions (11.9%) occurred with single-incision group versus 4 nonunions (18.2%) with dual-incision group (P = 0.479). Conclusions: This is the first study to compare a single-incision fasciotomy technique to a dual-incision technique in the setting of tibial fractures with ACS, with similar infection and nonunion rates with either technique. The choice of fasciotomy technique can be based on surgeon experience or patient condition as opposed to a suspected elevated infection or nonunion risk with either technique. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Results of Cephallomedullary Nail Fixation for Displaced Intracapsular Femoral Neck Fractures

Objective: To evaluate the outcomes of displaced intracapsular femoral neck fractures treated with a cephalomedullary device. Design: Retrospective study. Setting: Level I trauma center. Patients: Between 2002 and 2008, 18 patients with displaced intracapsular femoral neck fractures were treated at our Level I trauma center with a cephalomedullary nail. There were 12 males and six females. Six patients were younger than 60 years of age with a mean age of 63 years (range, 40–88 years). Thirteen fractures were midcervical (Orthopaedic Trauma Association [OTA] 31-B2.2 and B2.3), and five fractures were subcapital (OTA 31-B3). Patients with basicervical fractures (OTA 31-B2.1) and nondisplaced subcapital fractures (OTA 31-B1) were excluded. Intervention: All patients underwent cephalomedullary nail fixation of their femoral neck fractures under the supervision of fellowship-trained orthopaedic trauma surgeons. Main Outcome Measurements: Postoperative radiographs were evaluated for fracture reduction quality. Clinical follow-up was available on 13 patients with a minimum of 12 months (range, 12–25 months). A radiographic and chart review was done to identify complications and outcomes. Results: Seven of eight fractures that healed were anatomically reduced. No failures occurred in the six patients younger than 60 years. Fixation failed in five of 13 fractures (38.4%) with varus collapse as the typical failure mode. The mean time to failure in these cases was 3.8 months (range, 1–7 months). Overall, the failure rate for the subcapital fractures was 100% (three of three) and for midcervical 20% (two of 10) with all failures being in patients older than 60 years (71.4%). Osteonecrosis without fixation failure or cutout occurred in one case. Conclusion: Cephalomedullary nail fixation of displaced intracapsular femoral neck fractures demonstrated mixed results. For younger patients with midcervical fractures that were well reduced, the fixation performed well. Displaced subcapital fractures in patients older than 60 years demonstrated a 100% failure rate. As a result, we cannot advocate cephalomedullary fixation for displaced intracapsular femoral neck fractures in patients older than 60 years, although in younger patients, these implants may provide an alternative to side-plate based fixation devices.

Quantification of bony pelvic exposure through the modified Stoppa approach.

Objectives: Authors previously have described anatomic structures commonly seen through the modified Stoppa approach; however, no study has formally quantified the areas and amount of visual bony exposure that is obtained. This information is important for proper preoperative planning of acetabulum fractures with regard to fracture reduction and fixation. The aim of this study was to quantify and describe the extent of bony pelvis exposed while identifying the limits of exposure from osseous landmarks within the dissection of the modified Stoppa approach. Methods: Ten modified Stoppa approaches were performed on cadavers. Specific anatomic landmarks were identified, and the far boundaries of the exposed osseous structures from the surgeons perspective were marked on each cadaver. All soft tissues were then stripped, and calibrated digital images of the demarcated area of exposure were taken and total viewable osseous surface area was calculated. Additionally, the boundaries of exposure based on various anatomic landmarks were determined. Results: All neurovascular structures at potential risk (external iliac, obturator, corona mortis, and superior gluteal) were identified in each exposure. The entire pelvic brim from the pubic symphysis to beyond the sacroiliac joint was visualized in all exposures, with an average ± SD of 10 ± 5 mm of anterior sacrum exposed. On average, visualization above the pelvic brim was possible 15 ± 5 mm anteriorly over the acetabular roof and 19 ± 5 mm posteriorly above the greater sciatic notch. The viewable area included 51 ± 5 mm below the pelvic brim along the quadrilateral surface, with 41 ± 5 mm of the obturator foramen depth and 29 ± 9 mm of the greater sciatic notch seen on average. Approximately 32% ± 4% of the total surface area of the inner pelvis was able to be visualized, which included 79% ± 5% of the inner true pelvis below the brim and 80% ± 6% of the quadrilateral surface. Conclusions: The modified Stoppa approach allows for exposure of most (79%) of the inner true bony pelvis including the entire pelvic brim and 80% of the quadrilateral surface. On average, visualization is possible 2 cm above the pelvic brim and 5 cm below the pelvic brim along the quadrilateral surface, providing adequate anterior exposure for clamp and implant placement.

Building a clinical research network in trauma orthopaedics: The major extremity trauma research consortium (METRC)

Objectives: Lessons learned from battle have been fundamental to advancing the care of injuries that occur in civilian life. Equally important is the need to further refine these advances in civilian practice, so they are available during future conflicts. The Major Extremity Trauma Research Consortium (METRC) was established to address these needs. Methods: METRC is a network of 22 core level I civilian trauma centers and 4 core military treatment centers—with the ability to expand patient recruitment to more than 30 additional satellite trauma centers for the purpose of conducting multicenter research studies relevant to the treatment and outcomes of orthopaedic trauma sustained in the military. Early measures of success of the Consortium pertain to building of an infrastructure to support the network, managing the regulatory process, and enrolling and following patients in multiple studies. Results: METRC has been successful in maintaining the engagement of several leading, high volume, level I trauma centers that form the core of METRC; together they operatively manage 15,432 major fractures annually. METRC is currently funded to conduct 18 prospective studies that address 6 priority areas. The design and implementation of these studies are managed through a single coordinating center. As of December 1, 2015, a total of 4560 participants have been enrolled. Conclusions: Success of METRC to date confirms the potential for civilian and military trauma centers to collaborate on critical research issues and leverage the strength that comes from engaging patients and providers from across multiple centers.
