RESUMO

OBJECTIVES: To study the results of displaced femoral neck fractures (FNFs) in adults less than 60 years of age by comparing patients, injury, treatment, and the characteristics of treatment failure specifically according to patients' age at injury, that is, by their "decade of life" [ie, "under 30" (29 years and younger), "the 30s" (30-39 years), "the 40s" (40-49 years), and "the 50s" (50-59 years)]. DESIGN: Multicenter retrospective comparative cohort series. SETTING: Twenty-six North American Level 1 Trauma Centers. PATIENT SELECTION CRITERIA: Skeletally mature patients aged 18-59 years with operative repair of displaced FNFs. OUTCOME MEASURES AND COMPARISONS: Main outcome measures were treatment failures (fixation failure and/or nonunion, osteonecrosis, malunion, and the need for subsequent major reconstructive surgery (arthroplasty or proximal femoral osteotomy). These were compared across decades of adult life through middle age (<30 years, 30-39 years, 40-49 years, and 50-59 years). RESULTS: Overall, treatment failure was observed in 264 of 565 (47%) of all hips. The mean age was 42.2 years, 35.8% of patients were women, and the mean Pauwels angle was 53.8 degrees. Complications and the need for major secondary surgeries increased with each increasing decade of life assessed: 36% of failure occurred in patients <30 years of age, 40% in their 30s, 48% in their 40s, and 57% in their 50s (P < 0.001). Rates of osteonecrosis increased with decades of life (under 30s and 30s vs. 40s vs. 50s developed osteonecrosis in 10%, 10%, 20%, and 27% of hips, P < 0.001), while fixation failure and/or nonunion only increased by decade of life to a level of trend (P = 0.06). Reparative methods varied widely between decade-long age groups, including reduction type (open vs. closed, P < 0.001), reduction quality (P = 0.030), and construct type (cannulated screws vs. fixed angle devices, P = 0.024), while some variables evaluated did not change with age group. CONCLUSIONS: Displaced FNFs in young and middle-aged adults are a challenging clinical problem with a high rate of treatment failure. Major complications and the need for complex reconstructive surgery increased greatly by decade of life with the patients in their sixth decade experiencing osteonecrosis at the highest rate seen among patients in the decades studied. Interestingly, treatments provided to patients in their 50s were notably different than those provided to younger patient groups. LEVEL OF EVIDENCE: Prognostic Level III.

RESUMO

OBJECTIVES: The objective of this study was to determine the difference in failure rates of surgical repair for displaced femoral neck fractures in patients younger than 60 years of age according to fixation strategy. DESIGN: This is a retrospective, comparative cohort study. SETTING: Twenty-six Level 1 North American trauma centers. PATIENT SELECTION CRITERIA: Patients younger than 60 years of age with a displaced femoral neck fracture (OTA 31-B2, B3) undergoing surgical repair from 2005 to 2017. OUTCOME MEASURES AND COMPARISONS: Patient demographics, injury characteristics, repair methods used, and treatment failure (nonunion/failed fixation, avascular necrosis, and need for secondary surgery) were compared according to fixation strategy. RESULTS: Five hundred and sixty-five patients met inclusion criteria and were studied. The mean age was 42 years, 36% were female, and the average Pauwels' angle of fractures was 55 degrees. There were 305 patients treated with multiple cannulated screws (MCS) and 260 treated with a fixed-angle (FA) construct. Treatment failures were 46% overall, but was more likely to occur in MCS constructs versus FA devices (55% vs. 36%, P < 0.001). When FA constructs were substratified, the use of a sliding hip screw with addition of a medial femoral neck buttress plate (FNBP) and "antirotation" (AR) screw demonstrated better results than either FNBP or AR screw alone or neither with the lowest overall construct failure rate of 11% (P < 0.036). CONCLUSIONS: Historically used fixation constructs for femoral neck fractures (eg, multiple cannulated screws and sliding hip screw) in young and middle-aged adults performed poorly compared with more recently proposed constructs, including those using a medial femoral neck buttress plate and an antirotation screw. Fixed-angle constructs outperformed multiple cannulated screws overall, and augmentation of fixed-angle constructs with a medial femoral neck buttress plate and antirotation screw improved the likelihood of successful treatment. Surgeons should prioritize fixation decisions when repairing displaced femoral neck fractures in patients. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVE: To compare the bone healing effects of percutaneously delivered bone marrow aspirate concentrate (BMC) versus reamer irrigator aspirator (RIA) suspension in a validated preclinical canine ulnar nonunion model. We hypothesized that BMC would be superior to RIA in inducing bone formation across a nonunion site after percutaneous application. The null hypothesis was that BMC and RIA would be equivalent. METHODS: A bilateral ulnar nonunion model (n= 6; 3 matched pairs) was created. Eight weeks after segmental ulnar ostectomy, RIA from the ipsilateral femur and BMC from the proximal humerus were harvested and percutaneously administered into either the left or right ulnar defect. The same volume (3 ml) of RIA suspension and BMC were applied on each side. Eight weeks after treatment, the dogs were euthanized, and the nonunions were evaluated using radiographic, biomechanical, and histologic assessments. RESULTS: All dogs survived for the intended study duration, formed radiographic nonunions 8 weeks after segmental ulnar ostectomy, and underwent the assigned percutaneous treatment. Radiographic and macroscopic assessments of bone healing at the defect sites revealed superior bridging-callous formation in BMC-treated nonunions. Histologic analyses revealed greater amount of bony bridging and callous formation in the BMC group. Biomechanical testing of the treated nonunions did not reveal any significant differences. CONCLUSION: Bone marrow aspirate concentrate (BMC) had important advantages over Reamer Irrigator Aspirator (RIA) suspension for percutaneous augmentation of bone healing in a validated preclinical canine ulnar nonunion model based on clinically relevant radiographic and histologic measures of bone formation.

RESUMO

Background: Symptomatic acetabular labral insufficiency in young, active patients is often treated with labral repair or reconstruction using fresh-frozen allografts. However, fresh-frozen tendon allografts do not have tissue or material properties that closely mimic acetabular labral fibrocartilage. Recent studies suggest meniscal allografts may be a better biomechanical, geometric, and material alternative for acetabular labrum reconstruction (ALR). Hypothesis: Patients undergoing open ALR using fresh meniscus allograft transplants (MAT) will have better outcomes than those using fresh-frozen tendon allografts transplants (TAT) when comparing initial treatment success, diagnostic imaging assessments, and patient-reported pain and function scores. Study design: Cohort Study. Methods: With IRB approval, patients undergoing ALR with either TAT or MAT were included when initial (>1-year) outcomes data related to treatment success, pain, and function were available. In addition, a subcohort of patients underwent magnetic resonance imaging at least 6-months after surgery to evaluate allograft healing. Results: Initial success rate, defined as no need for ALR revision or conversion to total hip arthroplasty (THA), was 88.9% for the entire group (n = 27, TAT = 5, MAT = 22) with 1 (20%) patient in the TAT cohort and 2 patients (9.9%) in the MAT cohort undergoing THA. In the MAT cohort, significant improvements were documented for physical function and pain scores at 1 year and final follow-up (FFU)(mean 26.8 months). Improvements in pain and function were noted at 1-year, but not at FFU (mean 59.6 months) in the TAT group. MRIs completed at least 6 months after labrum reconstruction showed improved allograft integrity and integration in the MAT cohort over the TAT cohort. Conclusion: For acetabular labrum reconstructions, MAT was associated with a higher initial success rate, superior patient reported outcomes, and subjectively better MRI findings when compared to TAT.

RESUMO

Treatment options for symptomatic cartilage loss in the ankle are not consistently effective. This study documents initial outcomes for patients undergoing bipolar OCAT in the ankle after advances in tissue preservation, transplantation techniques, and patient management strategies were implemented. Patients were prospectively enrolled into a registry designed to follow outcomes after OCAT in the ankle. Fourteen patients were included for analyses (12 primary OCAT, 2 revision OCAT). Four patients underwent Bipolar OCAT (tibia, talus) and 10 Bipolar+ OCAT (tibia, talus, fibula). Short-term (median follow-up 43, range 13-73 months) success was documented for 13 patients. Radiographic assessments indicated OCA integration and maintenance of joint space in 12 patients. Statistically significant (p < .030) and clinically meaningful improvements in AAOS and VAS pain scores were noted at 3 months, 6 months, 1 year, and 2 years following OCA transplantation when compared to preoperative measures. For patients that were nonadherent to postoperative restriction and rehabilitation protocols, all 1-year postoperative PROs were significantly lower (p < .050) than for patients who were adherent. The successful outcomes documented in 13 of 14 patients in conjunction with significant and clinically meaningful improvements in patient-reported measures of pain and function support OCA transplantation as an appropriate treatment option in indicated patients. These improvements in outcomes were associated with advances in OCA preservation, preimplantation treatment, transplantation techniques, and patient management strategies, suggesting this shift in practice be considered for OCA transplantation in the ankle.

RESUMO

Effective nonunion and bone defect management requires consideration of multiple potential contributing factors including biomechanics, biology, metabolic, and patient factors. This article reviews these factors as well as several potential nonunion or bone defect treatments including bone grafts, bone graft substitutes, the induced membrane technique, and distraction osteogenesis. A summary of these concepts and guidelines for an overall approach to management are also provided.

RESUMO

Objective: Determine measurable differences for mechanistic urine and serum biomarkers in patients with developmental dysplasia of the hip (DDH) prior to, and following, secondary hip osteoarthritis (OA) when compared to controls. Design: Urine and serum were collected from individuals with developmental dysplasia of the hip (n = 39), prior to (Pre-OA DDH, n = 32) and following diagnosis of secondary hip OA (Post-OA DDH, n = 7), age-matched Pre-OA controls (n = 35), and age-matched Post-OA controls (n = 12). Samples were analyzed for protein biomarkers with potential for differentiation of hip status through a Mann-Whitney U test with a Benjamini-Hochberg correction. Results: Several interleukin and degradation related proteins were found to be differentially expressed when comparing DDH-related hip status prior to and following diagnosis of hip OA. In addition, MCP-1 and TIMP-1 were significantly different between younger and older patients in the control cohorts. Conclusion: These results provide initial evidence for serum and urine protein biomarkers that define clinically relevant stages of symptomatic DDH and its progression to secondary hip osteoarthritis categorized by known mechanisms of disease. Level of evidence: III.

RESUMO

The acetabular labrum is essential to maintaining the functional health of the hip joint through contributions to joint congruity, stability, and the negative pressure suction seal. Injury, overuse, long-standing developmental disorders, or failed primary labral repair can eventually lead to functional labral insufficiency requiring management via labral reconstruction. While numerous graft options exist for hip labral reconstruction, there is no current gold standard. The optimal graft should best mimic the native labrum with regard to geometry, structure, mechanical properties, and durability. This has led to the development of an arthroscopic technique for labral reconstruction with fresh meniscal allograft tissue.

RESUMO

OBJECTIVE: Evaluate serum and urine biomarker panels for their capabilities in discriminating between individuals (13- to 34-years-olds) with healthy hips versus those with developmental dysplasia of the hip (DDH) prior to diagnosis of secondary hip osteoarthritis (OA). DESIGN: Urine and serum were collected from individuals (15-33 years old) with DDH, prior to and following diagnosis of hip OA, and from age-matched healthy-hip controls. Samples were analyzed for panels of protein biomarkers with potential for differentiation of hip status using receiver operator characteristic curve (area under curve [AUC]) assessments. RESULTS: Multiple urine and serum biomarker panels effectively differentiated individuals with DDH from healthy-hip controls in a population at risk for developing secondary hip OA with the best performing panel demonstrating an AUC of 0.959. The panel comprised of two serum and two urinary biomarkers provided the highest combined values for sensitivity, 0.85, and specificity, 1.00, while a panel of four serum biomarkers provided the highest sensitivity, 0.93, while maintaining adequate specificity, 0.71. CONCLUSION: Results of this study indicate that panels of protein biomarkers measured in urine and serum may be able to differentiate young adults with DDH from young adults with healthy hips. These data suggest the potential for clinical application of a routine diagnostic method for cost-effective and timely screening for DDH in at-risk populations. Further development and validation of these biomarker panels may result in highly sensitive and specific tools for early diagnosis, staging, and prognostication of DDH, as well as treatment decision making and monitoring capabilities. LEVEL OF EVIDENCE: III.

RESUMO

OBJECTIVE: To assess key demographic and psychosocial variables that may be associated with non-adherence to clinic visits following orthopaedic trauma injuries to patients in an urban and rural population. METHODS: This retrospective review included all operative and non-operative patients presenting to a Level I academic trauma center serving an urban and rural population in the Midwest following an orthopaedic injury. The study tracked patient attendance to scheduled orthopaedic trauma follow-up clinic visits after a scheduled visit in the clinic following a trauma-related injury. RESULTS: Data were obtained for 5816 unique orthopaedic trauma patients who had 21,066 post-treatment follow-up visits scheduled. 1627 "no-show" appointments were recorded. Factors associated with no-shows included male sex, age between 26 and 35 years, self-reported race other than white, employment listed as disabled, household income below $25,000, education less than a high school level, uninsured, Medicaid insured, and relationship status reported as single. CONCLUSIONS: In the present study, key demographic and psychosocial factors were significantly associated with patient adherence to scheduled follow-up appointments after treatment for orthopaedic trauma. Identifying patients at higher risk for nonadherence will allow healthcare teams to educate patients, providers, and staff, link patients to resources to enhance adherence, and work with their institutions to develop and implement protocols for improving adherence to follow-up appointments.

RESUMO

OBJECTIVES: To evaluate mechanical treatment failure in a large patient cohort sustaining a distal femur fracture treated with a distal femoral locking plate (DFLP). DESIGN: This retrospective case-control series evaluated mechanical treatment failures of DFLPs. SETTING: The study was conducted at 8 Level I trauma centers from 2010 to 2017. PATIENTS AND PARTICIPANTS: One hundred one patients sustaining OTA/AO 33-A and C distal femur fractures were treated with DFLPs that experienced mechanical failure. INTERVENTION: The intervention included the treatment of a distal femur fracture with a DFLP, affected by mechanical failure (implant failure by loosening or breakage). MAIN OUTCOME MEASURE: The main outcome measures included injury and DFLP details; modes and timing of failure were studied. RESULTS: One hundred forty-six nonunions were found overall (13.4%) including 101 mechanical failures (9.3%). Failures occurred in different manners, locations, and times depending on the DFLPs. For example, 33 of 101 stainless steel (SS) plates (33%) failed by bending or breaking in the working length, whereas no Ti plates failed here ( P < 0.05). Eleven of 12 failures with titanium-Less Invasive Stabilization System (92%) occurred by lost shaft fixation, mostly by the loosening of unicortical screws (91%). Sixteen of 44 variable -angled-LCP failures (36%) occurred at the distal plate-screw junction, whereas only 5 of 61 other DFLPs (8%) failed this way ( P < 0.05). Distal failures occurred on average at 23.7 weeks compared with others that occurred at 38.4 weeks ( P < 0.05). Variable -angled-LCP distal screw-plate junction failures occurred earlier (mean 21.4 weeks). CONCLUSION: Nonunion and mechanical failure occurred in 14% and 9% of patients, respectively, in this large series of distal femur fracture treated with a DFLP. The mode, location, presence of a prosthesis, and timing of failure varied depending on the characteristics of DFLP. This information should be used to optimize implant usage and design to prolong the period of stable fixation before potential implant failures occur in patients with a prolonged time to union. LEVEL OF EVIDENCE: Economic Level IV. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

INTRODUCTION: Cephalomedullary nails (CMN) have proven to be effective for the fixation of unstable pertrochanteric hip fractures, but limited data exists regarding the degree of shortening that occurs with nailing systems that offer "dynamically" versus "statistically" locked helical blades. This study aimed to determine the incidence, timing, and amount of postoperative fracture shortening in patients with pertrochanteric hip fractures treated with "dynamically" versus "statistically" locked helical blades. METHODS: A retrospective review was performed on patients requiring operative fixation of pertrochanteric fractures. Inclusion criteria were patients aged 55 or older, low energy mechanism of injury, primary surgical open reduction and internal fixation of the injury, surgery performed by a fellowship-trained orthopaedic traumatologist, and radiographic follow up until healing or failure (minimum of 3 months). Quantification of fracture shortening was determined using the lateral screw protuberance method. Fracture shortening measurements were calculated from immediate post-operative films and subsequent radiographs at each follow-up visit. RESULTS: 222 patients met inclusion criteria (123 using Depuy Synthes Trochanteric Fixation Nail proximal femoral nailing system (TFN) with static locking; 65 TFN with dynamic locking; 23 using Depuy Synthes Trochanteric Fixation Nail-Advanced proximal nailing system (TFNA) with static locking; and 11 TFNA with dynamic locking). When comparing the final screw protuberance, the TFN dynamic (10.31 mm), TFNA static (9.52 mm), and TFNA dynamic (7.02 mm) groups were found to be significantly less compared to the TFN static cohort (11.67 mm; p < 0.001). The distribution of fracture shortening was found to be significant (p < 0.01). Interval measurements of fracture shortening by repeated measures of ANOVA within groups showed statistically significant increases in screw protuberance for the TFN static (p < 0.001), TFN dynamic (p < 0.001), and TFNA static (p < 0.01) cohorts within the first 60 days postoperatively. The TFNA with dynamic locking group was found to have statistically significant increases until the first 100 days post-operatively (p < 0.02). DISCUSSION: The incidence of fracture shortening remains high even with the use of cephalomedullary nails, regardless of dynamization status. Current pertrochanteric fixation constructs continue to favor fracture healing at the direct expense of fracture shortening.

RESUMO

➢: Arthroscopic hip labral reconstruction is a complex procedure which is growing in use as indications, techniques, and surgical expertise advance. ➢: Graft selection is an important component of labral reconstruction based on relative advantages and disadvantages of available types of autografts and allografts. ➢: The ideal graft should mimic the native acetabular labrum form and function while also being affordable, readily available, and associated with low morbidity. ➢: High rates of patient satisfaction and positive patient-reported outcomes have been reported after labral reconstruction using several graft types.

RESUMO

Background and objectives: Alignment of the lower extremity is important when treating congenital deformities, fractures, and joint replacement. During the COVID-19 pandemic, AO North America offered an online course on deformity measurement and planning. The Bonesetter app is a deformity planning tool that is freely available online. The purpose of this study was to see how effective an online course was in teaching axial alignment measurement and to assess that skill using an online digital planning tool, the Bonesetter app. Materials and Methods: An online module on axial alignment was provided during the AONA osteotomy course as well as a tutorial on how to use an online digital planning tool (Bonesetter app). The tools within the Bonesetter app allow users to draw digital lines directly on the CT images and measure the exact angle between two planes. Participants in this study were directed to perform these measurements in four different cases that tested different variations of deformity. Results: The measurements were completed correctly in case 1 = 56%, case 2 = 61%, case 3 = 84%, and case 4 = 76%. The standard deviation of angular digital measurements between individuals was ±4.26 degrees. Measuring the angle directly vs. drawing angles to a horizontal line had smaller standard deviations per case (p < 0.005) and less incidents outside 1 standard deviation for each measurement. Errors in adding and subtracting were the most common errors, particularly in relation to femoral anteversion or retroversion. Conclusions: The online course successfully instructed a group of orthopedic surgeons to measure alignment and malalignment of lower limb axial deformities. The Bonesetter app helped participants to learn this skill and identify errors in measurement. The inability to differentiate between anteversion and retroversion of the femur is a common source of error when it occurs and should be a focus of instruction.

RESUMO

The University of Missouri's Limb Preservation Center is a multi-disciplinary team helping patients with acute and chronic traumatic limb injuries, especially when faced with the difficult decision of limb preservation versus amputation. The team focuses on acute trauma and the chronic effects of a prior failed treatment, including possible amputation. This approach results in improved care, outcomes, and a decrease in failed treatment plans for patients. New advances in amputation techniques also provides better outcomes for patients.

RESUMO

The knee is a complex structure composed of bone, cartilage, menisci, ligaments and muscles, which all work synergistically to optimize congruence, stability, and function. Osteotomies are procedures addressing an abnormal joint alignment, shifting the mechanical load from a diseased joint compartment to a healthier one. Preoperative planning is an important art of identifying the source of abnormal load distribution to the joint, enabling the surgeon to simulate a deformity correction ahead of the surgical procedure.
