RESUMO

OBJECTIVES: To assess the relationship between patient smoking status and fracture-related infection (FRI) characteristics including patient symptoms at FRI presentation, bacterial species of FRI, and rates of fracture union. DESIGN: Retrospective cohort study. SETTING: Urban level 1 trauma center. PATIENT SELECTION CRITERIA: All patients undergoing reoperation for FRI from January 2013 to April 2021 were identified through manual review of an institutional database. OUTCOME MEASURES AND COMPARISONS: Data including patient demographics, fracture characteristics, infection presentation, and hospital course were collected through review of the electronic medical record. Patients were grouped based on current smoker versus nonsmoker status. Hospital course and postoperative outcomes of these groups were then compared. Risk factors of methicillin-resistant Staphylococcus aureus (MRSA) infection, Staphylococcus epidermidis infection, and sinus tract development were evaluated using multivariable logistic regression. RESULTS: A total of 301 patients, comprising 155 smokers (51%) and 146 nonsmokers (49%), undergoing FRI reoperation were included. Compared with nonsmokers, smokers were more likely male (69% vs. 56%, P = 0.024), were younger at the time of FRI reoperation (41.7 vs. 49.5 years, P < 0.001), and had lower mean body mass index (27.2 vs. 32.0, P < 0.001). Smokers also had lower prevalence of diabetes mellitus (13% vs. 25%, P = 0.008) and had higher Charlson Comorbidity Index 10-year estimated survival (93% vs. 81%, P < 0.001). Smokers had a lower proportion of S. epidermidis infections (11% vs. 20%, P = 0.037), higher risk of nonunion after index fracture surgery (74% vs. 61%, P = 0.018), and higher risk of sinus tracts at FRI presentation (38% vs. 23%, P = 0.004). On multivariable analysis, smoking was not found to be associated with increased odds of MRSA infection. CONCLUSIONS: Among patients who develop a FRI, smokers seemed to have better baseline health regarding age, body mass index, diabetes mellitus, and Charlson Comorbidity Index 10-year estimated survival compared with nonsmokers. Smoking status was not significantly associated with odds of MRSA infection. However, smoking status was associated with increased risk of sinus tract development and nonunion and lower rates of S. epidermidis infection at the time of FRI reoperation. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

Femoral neck fractures in physiologically young patients typically occur from high-energy axial loading forces through the thigh with the hip in an abducted position. These fractures have a high rate of associated head, chest, abdominal, and musculoskeletal injuries. High-energy hip fractures differ from traditional geriatric hip fractures regarding incidence, mechanism, management algorithms, and complications. After adequate resuscitation, goals of treatment include anatomic reduction and stable fixation while maintaining vascularity of the femoral head, which can be achieved through a variety of different techniques. Prompt recognition and treatment of these fractures is crucial to achieve a successful outcome because these injuries are often associated with complications such as osteonecrosis, fixation failure, and nonunion.

RESUMO

Pelvic ring injuries occur in varying severity and in vastly different patient demographics. Knowledge regarding which of these injuries require surgical intervention and which can be managed nonsurgically continues to evolve. Previous studies have shown validated criteria for sacral fractures and the posterior ring, explored the role of examination under anesthesia, and other forms of dynamic imaging. Although there is substantial information available, a comprehensive synthesis of this information is lacking. This article provides a comprehensive review of radiographic markers suggestive of stability, discusses treatment strategies, and proposes a treatment algorithm that is easily understood and applicable to not only those with a trauma background but also the general orthopaedic surgeon who will see these injuries frequently while on call.

RESUMO

BACKGROUND: The objective of this study was to investigate the outcomes of COVID-19-positive patients undergoing orthopaedic fracture surgery using data from a national database of U.S. adults with a COVID-19 test for SARS-CoV-2. METHODS: This is a retrospective cohort study using data from a national database to compare orthopaedic fracture surgery outcomes between COVID-19-positive and COVID-19-negative patients in the United States. Participants aged 18-99 with orthopaedic fracture surgery between March and December 2020 were included. The main exposure was COVID-19 status. Outcomes included perioperative complications, 30-day all-cause mortality, and overall all-cause mortality. Multivariable adjusted models were fitted to determine the association of COVID-positivity with all-cause mortality. RESULTS: The total population of 6.5 million patient records was queried, identifying 76,697 participants with a fracture. There were 7,628 participants in the National COVID Cohort who had a fracture and operative management. The Charlson Comorbidity Index was higher in the COVID-19-positive group (n = 476, 6.2 %) than the COVID-19-negative group (n = 7,152, 93.8 %) (2.2 vs 1.4, p<0.001). The COVID-19-positive group had higher mortality (13.2 % vs 5.2 %, p<0.001) than the COVID-19-negative group with higher odds of death in the fully adjusted model (Odds Ratio=1.59; 95 % Confidence Interval: 1.16-2.18). CONCLUSION: COVID-19-positive participants with a fracture requiring surgery had higher mortality and perioperative complications than COVID-19-negative patients in this national cohort of U.S. adults tested for COVID-19. The risks associated with COVID-19 can guide potential treatment options and counseling of patients and their families. Future studies can be conducted as data accumulates. LEVEL OF EVIDENCE: Level III.

RESUMO

Orthopaedics as a field and a profession is fundamentally concerned with the treatment of musculoskeletal disease, in all of its many forms. Our collective understanding of the cellular mechanisms underlying musculoskeletal pathology resulting from injury continues to evolve, opening novel opportunities to develop orthobiologic treatments to improve care. It is a long path to move from an understanding of cellular pathology to development of successful clinical treatment, and this article proposes to discuss some of the challenges to achieving translational therapies in orthopaedics. The article will focus on challenges that clinicians will likely face in seeking to bring promising treatments forward to clinical practice and strategies for improving success in translational efforts.

RESUMO

Sacral fractures are complex injuries that follow a bimodal distribution, typically involving acute high energy trauma in young adults and low energy trauma in older adults (> 65 years old). Nonunion is a rare but debilitating potential complication of undiagnosed or improperly managed sacral fractures. Various surgical techniques, including open reduction and internal fixation, sacroplasty, and percutaneous screw fixation, have been used to manage these fracture nonunions. In addition to reviewing the initial management of sacral fractures and the risk factors for fracture nonunion, this article describes techniques, specific cases and outcomes of these treatment strategies.

RESUMO

The purpose of this study was to investigate the association between pre-operative anemia and prolonged hospital stay among geriatric patients with operative femoral neck fractures. This retrospective cohort study was performed at a level I trauma center and included geriatric patients with femoral neck fractures (OTA/AO 31) and operative treatment with Current Procedural Terminology code 27236. Exclusion criteria were admission to the intensive care unit, evacuation of subdural hematoma, and conditions requiring exploratory laparotomy. A total of 207 individuals, with data collected between January 2015 and August 2019 and age 65 years and older, were included in the analysis. Linear regression was used to evaluate the association between anemia and length of stay adjusting for potential confounders. Anemia was defined using preoperative hematocrit. The primary outcome was prolonged length of stay, defined as 5 or more days. The group was 65% women. The mean age was 80.2 years (range, 64-98 years). The majority (61%) of patients had anemia. American Society of Anesthesiologists classification was associated with preoperative anemia (P=.02). Patients with anemia had a 16% higher risk of prolonged length of stay compared with patients without anemia (81% vs 65%, P=.009). In the linear regression model, preoperative hematocrit was associated with length of stay (P=.032) when adjusted for sex, age, preoperative tranexamic acid, preoperative hemoglobin, postoperative hemoglobin, and postoperative hematocrit. Length of stay was approximately 1 week in this study, with anemia being a statistically significant risk factor for prolonged length of stay. Health care providers and administrators can consider anemia on admission when predicting length of stay. [Orthopedics. 2023;46(4):211-217.].

RESUMO

Open pelvic ring injuries are rare clinical entities that require multidisciplinary care. Due to the scarcity of this injury, there is no well-defined treatment algorithm. As a result, conflicting evidence surrounding various aspects of care including wound management and fecal diversion remain. Previous studies have shown mortality reaching 50% in open pelvic ring injuries, nearly five times higher than closed pelvic ring injuries. Early mortality is due to exsanguinating hemorrhage, while late mortality is due to wound sepsis and multiorgan system failure. With advancements in trauma care and ATLS protocols, there has been an improved survival rate reported in published case series. Major considerations when treating these injuries include aggressive resuscitation with hemorrhage control, diagnosis of associated injuries, prevention of wound sepsis with early surgical management, and definitive skeletal fixation. Classification systems for categorization and management of bony and soft tissue injury related to pelvic ring injuries have been established. Fecal diversion has been proposed to decrease rates of sepsis and late mortality. While clear indications are lacking due to limited studies, previous studies have reported benefits. Further large-scale studies are necessary for adequate evaluation of treatment protocols of open pelvic ring injuries. Understanding the role of fecal diversion, avoidance of primary closure in open pelvic ring injuries, and importance of well-coordinated care amongst surgical teams can optimize patient outcomes.

RESUMO

Traumatic hemipelvectomy (THP) is a catastrophic injury associated with high-energy trauma and high mortality. THP has been defined as a complete dislocation of the hemipelvis, often with disruption through the symphysis pubis and sacroiliac joint with concurrent traumatic rupture of the iliac vessels. Despite recent advances in prehospital resuscitative techniques, the true incidence of THP is difficult to ascertain because many patients die before hospital arrival. The leading causes of death associated with THP include blood loss, infection, and multiple system organ failure. Recognition and immediate intervention for these injuries is imperative for survival. The initial assessment includes a thorough physical examination assessing for signs of arterial damage and other associated injuries. Hemorrhage control and vigorous resuscitation should be prioritized to combat impending exsanguination. Emergent amputation has been found to be a lifesaving operation in these patients. The basis of this approach is rooted in achieving complete hemostasis while reducing complication rates. Understanding the nature of these massive pelvic injuries, the role of early amputation, and the importance of subspecialty communication can improve survivability and optimize patient outcomes.

RESUMO

INTRODUCTION: Phantom limb syndrome is a debilitating complication after extremity amputation that poses significant challenges to recovery. This study aims to examine the relationship between phantom limb syndrome and mental and physical comorbidities, including a comparison between phantom limb pain and phantom limb syndrome without pain in below knee amputees. METHODS: This is a retrospective cohort study of patients who underwent below knee amputation of the lower extremity in the PearlDiver database, as identified using CPT codes. Analysis was carried out to evaluate the absence or presence of phantom limb syndrome. Matched bivariate analysis accounting for age, sex, Charlson Comorbidity Index score, and region was used to assess whether the presence of pain in phantom limb syndrome patients was associated with increased comorbidity. RESULTS: In total, 44,028 patients with below knee amputation were examined: 95% (42,493 patients) did not develop phantom limb syndrome while 4.8% (1,535 patients) of patients did develop phantom limb syndrome. Phantom limb syndrome was significantly associated with increased odds of coexistent major depressive disorder (OR = 1.86, p <0.0001), generalized anxiety disorder (OR = 2.14, p = 0.04), posttraumatic stress disorder (OR = 1.7, p <0.0001), suicidal ideation (OR = 1.62, p <0.0001), obesity (OR = 1.28, p = 0.0007), osteoarthritis (OR = 1.53, p <0.0001), osteoporosis (OR = 1.64, p <0.0001), and low back pain (OR = 2.31, p <0.0001). Analysis of patient cohorts of phantom limb syndrome with pain and those without pain did not reveal a statistically significant relationship between the presence of pain and any dependent variable. CONCLUSIONS: This investigation of over 44,000 patients with below knee amputation revealed that patients with phantom limb syndrome exhibit significantly higher rate of psychiatric comorbidities compared to those without documented phantom limb pain. Suicidal ideation, major depressive disorder, generalized anxiety disorder, and post-traumatic stress disorder were especially common, and consequently a multi-disciplinary approach to management is essential.

RESUMO

BACKGROUND: This study investigated the outcomes of coronavirus disease (COVID-19)-positive patients undergoing hip fracture surgery using a national database. METHODS: This is a retrospective cohort study comparing hip fracture surgery outcomes between COVID-19 positive and negative matched cohorts from 46 sites in the United States. Patients aged 65 and older with hip fracture surgery between March 15 and December 31, 2020, were included. The main outcomes were 30-day all-cause mortality and all-cause mortality. RESULTS: In this national study that included 3303 adults with hip fracture surgery, the 30-day mortality was 14.6% with COVID-19-positive versus 3.8% in COVID-19-negative, a notable difference. The all-cause mortality for hip fracture surgery was 27.0% in the COVID-19-positive group during the study period. DICUSSION: We found higher incidence of all-cause mortality in patients with versus without diagnosis of COVID-19 after undergoing hip fracture surgery. The mortality in hip fracture surgery in this national analysis was lower than other local and regional reports. The medical community can use this information to guide the management of hip fracture patients with a diagnosis of COVID-19.

RESUMO

BACKGROUND: Proximal humerus fractures (PHFs) are managed with open reduction and internal fixation (ORIF), hemiarthroplasty (HA), reverse shoulder arthroplasty (RSA), or nonoperatively. Given the mixed results in the literature, the optimal treatment is unclear to surgeons. The purpose of this study was to survey orthopedic shoulder and trauma surgeons to identify the patient- and fracture-related characteristics that influence surgical decision-making. METHODS: We distributed a 23-question closed-response email survey to members of the American Shoulder and Elbow Surgeons and Orthopaedic Trauma Association. Questions posed to respondents included demographics, surgical planning, indications for ORIF and arthroplasty, and the use of surgical augmentation with ORIF. Numerical and multiple-choice responses were compared between shoulder and trauma surgeons using unpaired t-tests and χ2 tests, respectively. RESULTS: Respondents included 172 shoulder and 78 trauma surgeons. When surgery is indicated, most shoulder and trauma surgeons treat 2-part (69%) and 3-part (53%) PHFs with ORIF. Indications for managing PHFs with arthroplasty instead of ORIF include an intra-articular fracture (82%), bone quality (76%), age (72%), and previous rotator cuff dysfunction (70%). In patients older than 50 years, 90% of respondents cited a head-split fracture as an indication for arthroplasty. Both shoulder and trauma surgeons preferred RSA for treating PHFs presenting with a head-split fracture in an elderly patient (94%), pre-existing rotator cuff tear (84%), and pre-existing glenohumeral arthritis with an intact cuff (75%). Similarly, both groups preferred ORIF for PHFs in young patients with a fracture dislocation (94%). In contrast, although most trauma surgeons preferred to manage PHFs in low functioning patients with a significantly displaced fracture or nonreconstructable injury nonoperatively (84% and 86%, respectively), shoulder surgeons preferred either RSA (44% and 46%, respectively) or nonoperative treatment (54% and 49%, respectively) (P < .001). Similarly, although trauma surgeons preferred to manage PHFs in young patients with a head-split fracture or limited humeral head subchondral bone with ORIF (98% and 87%, respectively), shoulder surgeons preferred either ORIF (54% and 62%, respectively) or HA (43% and 34%, respectively) (P < .001). CONCLUSIONS: ORIF and HA are preferred for treating simple PHFs in young patients with good bone quality or fracture dislocations, whereas RSA and nonoperative management are preferred for complex fractures in elderly patients with poor bone quality, rotator cuff dysfunction, or osteoarthritis. The preferred management differed between shoulder and trauma surgeons for half of the common PHF presentations, highlighting the need for future research.

RESUMO

BACKGROUND: Implants are a significant contributor to health care costs. We hypothesized that extra-articular fracture patterns would have a lower implant charge than intra-articular fractures and aimed to determine risk factors for increased cost. METHODS: In total, 163 patients undergoing outpatient distal radius fracture fixation at 2 hospitals were retrospectively reviewed stratified by Current Procedural Terminology codes. Implants and associated charges were noted, as were sex, age, insurance status, surgeon specialty, and location. Bivariate and multivariable regression were used to determine associations. RESULTS: Total implant charges were significantly lower for 25607 (extraarticular, $3,348) than 25608 (2-part intraarticular, $3,859) and 25609 (3+ part intraarticular, $3,991). In addition, intra-articular fractures had higher charges for distal screws/pegs and bone graft. Charge was lower when surgery was performed at a trauma center. There was no charge difference associated with insurance status, age, sex, hand surgery specialty, or fellow status. Substantial intersurgeon variation existed in all fracture types. CONCLUSION: Distal radius fractures may represent a good model for examining implant costs. Extra-articular fractures had lower implant charges than intra-articular fractures. These data may be used to help construct pricing for distal radius fracture bundles and potential cost savings.

RESUMO

➤: Oxidative stress has been implicated as a causative factor in many disease states, possibly including the diminished bone mineral density in osteoporosis. ➤: Understanding the effects of oxidative stress on the development of osteoporosis may lead to further research improving preventative and therapeutic measures that can combat this important contributor to morbidity and mortality worldwide. ➤: A diet rich in whole plant foods with high antioxidant content along with antioxidant-preserving lifestyle changes may improve bone mineral density and reduce the risk of fragility-related fractures. While it is not explicitly clear if antioxidant activity is the effector of this change, the current evidence supports this possibility. ➤: Supplementation with isolated antioxidants may also provide some osteoprotective benefits, but whole plant food-derived antioxidants potentially have more overall benefits. Larger-scale clinical trials are needed to give credence to definitive clinical recommendations.

RESUMO

BACKGROUND: Posterior malleolus fractures are traditionally managed with open reduction and internal fixation or percutaneous anterior-to-posterior screws. We present a third option using a percutaneous technique for the placement of posterior-to-anterior-directed screws. An anatomic safety analysis is done using cadaveric specimens. METHODS: Using 15 embalmed specimens (10 F and 5 M), a guidewire was placed using the described technique. The posterolateral ankle was dissected to evaluate for damage to vulnerable structures including the sural nerve, peroneal artery, and flexor hallucis longus/flexor digitorum longus/peroneal/Achilles tendons. The distance from the sural nerve and peroneal artery was measured to the guidewire at its nearest point. The tendons were evaluated for traumatic piercings. RESULTS: The sural nerve had a mean distance to wire of 5.3 mm (range 0 to 12) and the peroneal artery had a mean distance to wire of 5.7 mm (range 2 to 13 mm) with no traumatic piercings of either structure. The flexor hallucis longus/flexor digitorum longus/peroneal/Achilles tendons had no traumatic piercings. CONCLUSION: This percutaneous technique provides a safe alternative to the standard open and traditional percutaneous techniques. It has limited application and is suitable for noncomminuted minimally displaced posterior malleolus fractures and those with fragile tissues where the morbidity of the soft tissue exposure outweighs the benefit of an open reduction.

RESUMO

INTRODUCTION: A simple antibiotic prophylaxis initiative can effectively decrease the time to antibiotic administration for patients with open fractures. We aim to determine whether adherence to the protocol decreased over time without active input from the orthopaedic trauma team. PATIENTS AND METHODS: This retrospective cohort study included adult patients with open fractures (excluding hand) presenting directly to the emergency department at one Level I trauma center. Three separate 50-patient groups were included: a preimplementation cohort, immediately postimplementation cohort, and a retention cohort 2 years later. The primary outcome was time from emergency department presentation to antibiotic administration, and secondary outcomes were the percentage of patients receiving antibiotics within 60 minutes and incidence of infection requiring revision surgery within 90 days. The χ2 and Student t-tests evaluated between-group differences, and multivariable linear or logistic regression evaluated risk factors. RESULTS: After implementation, the time from presentation to antibiotic administration decreased markedly from 123.1 to 35.7 minutes and remained durable (50.0 minutes) at retention. The proportion of patients receiving antibiotics within 60 minutes increased markedly from 46% preimplementation to 82% postintervention and remained similar at retention (80%). The postintervention and retention groups were markedly more likely to receive antibiotics within 60 minutes than the preintervention group (odds ratio [OR], 8.4 and 4.7, respectively), as were patients with a higher Gustilo-Anderson type (OR, 2.4/unit increase), lower extremity injury (OR, 2.8), and male sex (OR, 3.1); mechanism, age, and Injury Severity Score were not associated. No difference was observed in infection. CONCLUSIONS: Our educational initiative showed durable results in reducing the time from presentation to antibiotic administration after 2 years. LEVEL OF EVIDENCE: Therapeutic Level III.

RESUMO

Reconstruction of segmental diaphyseal bone defects has been a major challenge in limb salvage surgery. Staged reconstruction as first described by Masquelet is a common strategy to deal with this problem in limb salvage surgery. One consequence of this technique is a time period of prolonged limited weightbearing while the segmental defect heals. The purpose of this study was to describe an adjunctive technique for stage II of the Masquelet procedure and retrospectively analyze the outcome and weight bearing progression of 3 patients who sustained femur fractures with significant bone loss and underwent this technique. A retrospective chart review was performed. The patients (2 males, 1 female with an average age of 36.6 years) all sustained segmental femur fractures which resulted in significant bone loss. Induced membrane technique with adjunct use of a fibular strut allograft was performed after initial stabilization and PMMA spacer placement. All three patients went on to union and full weight bearing after being treated by the described technique. All the patients were allowed toe-touch weight bearing immediately after surgery and all progressed to weight bearing as tolerated at an average of 3.6 months. Using a fibular strut allograft as an adjunct to the induced membrane technique serves as a biologic and mechanical scaffold and may allow earlier weightbearing.

RESUMO

BACKGROUND: Animal models have been used for decades to simulate human fractures in the laboratory setting. Fracture models in mice are attractive because they offer a high volume, relatively low-cost method of investigating fracture healing characteristics. We report on the development of a novel murine femur fracture model that is rapid, reproducible and inexpensive. METHODS: As part of a pilot study to investigate the effects of smoking on fracture healing, fifteen 35-43 g twelve-week old female CD-1 mice underwent a novel surgical protocol using direct visualization of femur fracture creation and fixation. Following surgery, mice were sacrificed at 14 days, 28 days and 42 days. After sacrifice, the femora were analyzed using MicroCT and histology to evaluate progression of healing. RESULTS: Of the 14 mice that survived the surgical procedure (one succumbed to a complication of anesthesia), two lost reduction and did not heal. Histology demonstrated at 14 days 44.1% (SD±2.9%) of callus composed of cartilage. At 28 days there was 19.0% (SD±3.4%) of callus composed of cartilage. At 42 days there was 8.4% (SD±2.6%) callus composed of cartilage (p < 0.005). MicroCT demonstrated that from 14 to 42 days the average callus volume decreased from 101.6 mm3 to 68.2 mm3 while the relative bone volume of callus increased from 14 to 42 days (15%-31%) (p = 0.068). CONCLUSIONS: Our novel fracture and fixation model is an effective, rapid, reproducible and inexpensive method to simulate a fracture in a laboratory setting. Additionally, our model reliably creates a reproducible progression of radiographic and histological bone healing.

RESUMO

Infection following total hip arthroplasty can be a devastating complication, often necessitating a 2-stage surgery with the temporary placement of an antibiotic spacer. Fracture around this spacer is an uncommon complication that presents serious treatment challenges. Our manuscript details the successful surgical treatment of a previously unreported fracture around an antibiotic spacer, treated with revision to a hemiarthroplasty and placement of an antibiotic plate.

RESUMO

Acetabular articular impaction may well accompany acetabular fractures. Anatomic restoration of acetabular congruence is imperative to achieve longevity of the hip joint. Combination of incarcerated acetabular impaction with osteochondral femoral fracture is a true challenge for the pelvic surgeon to address. We describe a technique to treat a posterior column acetabular fracture in association with incarcerated articular impaction and concomitant osteochondral femoral fracture. Posterior wall osteotomy combined with surgical hip dislocation facilitates the restoration of femoral head anatomy and acetabular surface integrity. This technique should be considered when dealing with this difficult scenario.
