RESUMO
INTRODUCTION: Femoral neck shortening is a common phenomenon following osteosynthesis for femoral neck fractures, which was shown to have a negative effect on hip function. There is paucity of literature on the effect of shortening on the ipsilateral limb mechanical axis and knee coronal alignment. We hypothesized that postoperative femoral neck shortening can alter the limb's mechanical axis into valgus. METHODS: Of 583 patients screened, 13 patients with severe neck shortening (< 10 mm) following femoral neck fracture fixation, were found eligible and agreed to participate. A full-length lower limb radiographs were obtained and radiographic parameters (offset, neck-shaft angle, HKA, mLPFA, mDLFA, mMPTFA, MAD, MAD-r) as well as functional scores were obtained. RESULTS: Statistically significant differences in mechanical axis deviation ratio (MAD-r) were found between the ipsilateral and the contralateral extremities (0.41 ± 0.16 versus 0.55 ± 0.11, p = 0.03). A correlation between femoral neck length differences and MAD was not statistically significant although a tendency towards lateral deviation of the mechanical axis was noted (r = - 0.5, p = 0.077). A negative correlation was found between a greater difference in the femoral neck length and the SF12 score, both in the physical and the mental parts (r = - 0.69, p = 0.008; r = - 0.58, p = 0.035, respectively). CONCLUSION: We found a more lateralized mechanical axis in limbs that demonstrated post-operative ipsilateral femoral neck severe shortening. These findings may provide a possible explanation and rationale for knee pain and perhaps for the development of knee osteoarthritis as a sequalae of femoral neck shortening. Further investigation and larger cohort, long-term studies are needed to further explore this hypothesis.

INTRODUCTION: Hip fractures in the elderly are related to increased mortality. The identification of patients at risk is essential. Several nutritional and inflammatory parameters were investigated in an effort to find a prognostic indicator for mortality following fragility hip fractures (FHF) surgery. We aim to evaluate their utility and compare between the different factors. METHODS: A retrospective cohort study of patients 65 years and older, who underwent surgery following fragility hip fractures between January 2012 and June 2020, was conducted. Patients who died within 90 days were matched at a 1:1 ratio with surviving controls, based on age, gender, fracture type, and comorbidities. Nutritional and inflammatory indices, including serum albumin, protein energy malnutrition (PEM), albumin-to-globulin ratio (AGR), prognostic nutritional index (PNI), the systemic immune-inflammation index (SII), platelet-to-lymphocyte ratio (PLR), and the neutrophile-to-lymphocyte ratio (NLR), were compared between groups. RESULTS: 304 patients were included, 152 in each group. Patients' demographics were similar. Among all indices evaluated, only the PLR significantly differed between the study groups (236.9 ± 193.5 for the study group vs. 186.6 ± 119.3 for the control group (p = 0.007). In patients who survived the initial hospitalization, the PEM was also found to be correlated with 90 days mortality. DISCUSSION: The PLR was found to be correlated with mortality risk following FHF surgery. As it can be easily calculated from accessible blood tests, we recommend its' routine assessment as a screening tool for personalized management of patients at high risk for mortality.
RESUMO
Acute distal patella tendon avulsion from the tibial tubercle (TT) is a relatively rare injury that is usually described in the adolescents or elderly population in their 7th or 8th decades. Bifocal avulsion fractures of the patella tendon from the TT and the distal pole of the patella are exceptionally rare in adults. In this case report, we present a 52-year-old healthy old male who was treated for bifocal avulsion of the patellar tendon with open reduction and internal fixation augmented with two ULTRATAPE sutures. To our knowledge, this is the first case report to describe this injury in a healthy middle-aged patient.

Introduction: Anticoagulation use in the elderly is common for patients undergoing femoral neck hip surgery. However, its use presents a challenge to balance it with associated comorbidities and benefits for the patients. As such, we attempted to compare the risk factors, perioperative outcomes, and postoperative outcomes of patients who used warfarin preoperatively and patients who used therapeutic enoxaparin. Methods: From 2003 through 2014, we queried our database to determine the cohorts of patients who used warfarin preoperatively and the patients who used therapeutic enoxaparin. Risk factors included age, gender, Body Mass Index (BMI) > 30, Atrial Fibrillation (AF), Chronic Heart Failure (CHF), and Chronic Renal Failure (CRF). Postoperative outcomes were also collected at each of the patients' follow-up visits, including number of hospitalization days, delays to theatre, and mortality rate. Results: The minimum follow-up was 24 months and the average follow-up was 39 months (range: 24-60 months). In the warfarin cohort, there were 140 patients and 2055 patients in the therapeutic enoxaparin cohort. Number of hospitalization days (8.7 vs. 9.8, p = 0.02), mortality rate (58.7% vs. 71.4%, p = 0.003), and delays to theatre (1.70 vs. 2.86, p < 0.0001) were significantly longer for the anticoagulant cohort than the therapeutic enoxaparin cohort. Warfarin use best predicted number of hospitalization days (p = 0.00) and delays to theatre (p = 0.01), while CHF was the best predictor of mortality rate (p = 0.00). Postoperative complications, such as Pulmonary Embolism (PE) (p = 0.90), Deep Vein Thrombosis (DVT) (p = 0.31), and Cerebrovascular Accidents (CVA) (p = 0.72), pain levels (p = 0.95), full weight-bearing status (p = 0.08), and rehabilitation use (p = 0.34) were similar between the cohorts. Conclusion: Warfarin use is associated with increased number of hospitalization days and delays to theatre, but does not affect the postoperative outcome, including DVT, CVA, and pain levels compared to therapeutic enoxaparin use. Warfarin use proved to be the best predictor of hospitalization days and delays to theatre while CHF predicted mortality rate.
RESUMO
STUDY DESIGN: Retrospective case series analysis. OBJECTIVE: To identify relevant clinical and radiographic markers for patients presenting with infectious spondylo-discitis associated with spinal instability directly related to the infectious process. METHODS: We evaluated patients presenting with de-novo intervertebral discitis or vertebral osteomyelitis /discitis (VOD) who initiated non-surgical treatment. Patients who failed conservative treatment and required stabilization surgery within 90 days were defined as "failed treatment group" (FTG). Patients who experienced an uneventful course served as controls and were labeled as "nonsurgical group" (NSG). A wide array of baseline clinical and radiographic parameters was retrieved and compared between 2 groups. RESULTS: Overall 35 patients had initiated non-surgical treatment for VOD. 25 patients had an uneventful course (NSG), while 10 patients failed conservative treatment ("FTG") within 90 days. Factors found to be associated with poorer outcome were intra-venous drug abuse (IVDA) as well as the presence of fever upon initial presentation. Radiographically, involvement of the same-level facets and the extent of caudal and rostral VB involvement in both MRI and CT were found to be significantly associated with poorer clinical and radiographic outcome. CONCLUSIONS: We show that clinical factors such as IVDA status and fever as well as the extent of osseous and posterior element involvement may prove to be helpful in favoring surgical treatment early on in the management of spinal infections.
RESUMO
Introduction: Wide resections of periacetabular tumors create a sizeable bony defect that inevitably results in severe loss of function. Reconstruction of such defects usually requires using large metal implants, a feature associated with considerable surgery extension and complications. The aim of this study is to report resection with no reconstruction of the bony defect. In this retrospective study, we reviewed a consecutive series of 16 patients diagnosed with malignant periacetabular tumors and underwent en-bloc resection without reconstructing their remaining bone defect. Methods: Records were reviewed of 16 consecutive patients diagnosed with malignant periacetabular tumors and underwent en-bloc resection without reconstructing their remaining bony defect. Measurements included: the duration of surgery, blood loss, hemoglobin levels and the need for blood transfusions, data on other hospitalization characteristics, and intraoperative and postoperative complications. Results: Sixteen patients with malignant periacetabular bone tumors and extensive bone destruction underwent wide periacetabular tumor resection with a mean follow-up of 75 months and a mean age of 53 years. The average HOOS score was 46 (range: 20 to 76), and the mean MSTS score was 13% (range: 0 to 15). The mean operative time was 4.1â h, and the mean blood loss was 1200â ml. At their most recent follow-up, patients had a mean shortening of their operated extremity of 4.8â cm, and all could ambulate with assisting devices. Conclusion: Wide resection of periacetabular tumors without reconstruction provides acceptable levels of function and was associated with shorter surgical time, less blood loss and fewer postoperative complications compared to resection with reconstruction. Therefore, this approach may be considered a viable surgical option in patients with an extensive malignant periacetabular. Level III: Retrospective study.
RESUMO
Platelet-Rich Plasma (PRP) injection has become a desirable alternative to Partial Plantar Fasciotomy (PPF) surgery and steroid injection for patients with chronic plantar fasciitis (CPF) due to its potential for shorter recovery times, reduced complications, and similar activity scores. As such, we compared PRP treatment to PPF surgery in patients with CPF. Between January 2015 and January 2017, patients were randomly divided into two groups, a PRP treatment group, and a PPF group. All procedures were performed by a single foot and ankle fellowship-trained specialist surgeon. Visual Analog Score (VAS) and Roles-Maudsley Scale (RM) were collected during the preoperative visit and 3, 6, and 12 months postoperatively. The patients were also closely followed by a physiotherapist. There were 16 patients in each group after four patients refused to participate. Patients in the PPF had low Roles-Maudsley Scale (RM) scores compared to the PRP group one-year after treatment (3.77 vs. 2.72, p < 0.0001). Both procedures showed a reduction in RM scores during the follow-up year (9 to 1.62 for PPF and 8.7 to 2.4 for PRP). There was no significant change in VAS pain between the two groups (p = 0.366). Patients treated with PRP injection reported a significant increase in their activity scores, shorter recovery time, and lower complication rates compared to PPF treatment. Moreover, with respect to existing literature, PRP may be as efficient as steroid injection with lower complication rates, including response to physical therapy. Therefore, PRP treatment may be a viable option before surgery as an earlier line treatment for CPF. Level of Clinical Evidence: II.

INTRODUCTION: Shoulder dislocation occurs when the head of the humerus disengages from the glenoid bone. About 95% of shoulder dislocations are traumatic, while the other 5% are not trauma-related in a patient with predisposing factors such as generalized ligamentous laxity. Ninety percent of shoulders dislocate anteriorly from direct force on the arm in the "ABER" position (Abduction- External Rotation). Usually, dislocations are accompanied by injuries to the shoulder that may lead to recurrent anterior shoulder instability and in the long-run, osteoarthritis of the shoulder joint. In the case of traumatic shoulder dislocation in the younger population or competitive sport players, accompanied with bone injury on X-ray's (Bony Bankart or Hill-Sachs), surgical treatment is recommended as soon as possible to avoid recurring dislocation and further joint damage. There are several options to treat recurrent shoulder instability, including soft tissue procedures, bone procedures, and a combination of these procedures. Surgery can be performed by an open or arthroscopic approach.

INTRODUCTION: Total joint arthroplasty (TJA) is amongst the most common elective orthopedic surgeries. Since their introduction in 1951 there have been changes not only in prosthesis design and surgical approaches, but also in patient management, anesthesia, drug regimen and robotic arm assistance. These changes led to advancement in patient safety and shorter hospitalization. Today TJA is accessible for a wider age and function range of patients, which has led to an exponential growth in the number of procedures conducted.

INTRODUCTION: Proximal femur fractures are associated with an increased mortality rate in the elderly. Early weight-bearing presents as a modifiable factor that may reduce negative postoperative outcomes and complications. As such, we aimed to compare non-weight-bearing, partial-weight-bearing and full weight-bearing cohorts, in terms of risk factors and postoperative outcomes and complications. METHODS: We retrospectively reviewed our database to identify the three cohorts based on the postoperative weight-bearing status the day of surgery from 2003 to 20014. We collected data on numerous risk factors, including age, cerebrovascular accident (CVA), pulmonary embolism (PE), surgical fixation method and diagnosis type. We also collected data on postoperative outcomes, including the number of days of hospitalization, pain levels, and mortality rate. We performed a univariate and multivariate analysis; P < 0.05 was the significant threshold. RESULTS: There were 186 patients in the non-weight-bearing group, 127 patients in the partial-weight-bearing group and 1791 patients in the full weight-bearing group. We found a significant difference in the type of diagnosis between cohorts (P < 0.001 in univariate, P < 0.001 in multivariate), but not in fixation type (P < 0.001 in univariate, but P = 0.76 in multivariate). The full weight-bearing group was diagnosed most with pertrochanteric fracture, 48.0%, and used Richard's nailing predominantly. Finally, we found that age was not a significant determinant of mortality rate but only weight-bearing cohort (P = 0.13 vs. P < 0.001, respectively). CONCLUSION: We recommend early weight-bearing, which may act to decrease the mortality rate compared to non-weight-bearing and partial weight-bearing. In addition, appropriate expectations and standardizations should be set since age and type of diagnosis act as significant predictors of weight-bearing status.

BACKGROUND: Reverse oblique intertrochanteric fractures are classified by the AO/OTA as 31A3 and account for 2-23% of all trochanteric fractures. The Gamma 3-Proximal Femoral Nail (GPFN) and the Expendable Proximal Femoral Nail (EPFN) are among the various devises used to treat this fracture. The aim of this study was to compare outcomes and complication rates in patients with AO/OTA 31A1-3 fractures, treated by either a GPFN or an EPFN. PATIENTS AND METHODS: A total of 67 patients (40 in the GPFN group and 27 in the EPFN group, average age 78.8 years) were treated in our institution between July 2008 and February 2016. Data on postoperative radiological variables, including peg location and tip-apex distance (TAD), as well as orthopedic complications, such as union rate, surgical wound infection and cut-outs rates were also recorded, along with the incidence of non-orthopedic complications and more surgical data. Functional results were evaluated and quantified using the Modified Harris Hip Score (MHHS) and by the Short Form 12 Mental Health Composite questionnaire (SF-12 MHC) in order to assess the quality of life. RESULTS: The total prevalence of postoperative orthopedic complications including postoperative infection showed a significant difference with a p-value of 0.016 in favor of the EPFN group. Nonetheless, the frequency of revision did not differ between the two groups, being 0.134. The main orthopedic complication in both groups was head cut-out of the GPFN lag screw and the EPFN expendable peg, which was 20% and 7.4%, respectively, and required a revision surgery using a long nail or total hip replacement (THR). However, the average TAD did not significantly differ between groups which might be due to a relatively low cohort to reach a significant difference. Nonunion rate of 5% occurred solely in the GPFN group, with similar results of intraoperative open reduction between both groups. The EPFN group achieved better scores in both questionnaires (p = 0.027 and p = 0.046, respectively). Both the MHHS and SF-12 MCS values significantly differed between groups, with the EPFN group achieving better scores than the GPFN group in both questionnaires (p = 0.027 and p < 0.05, respectively). CONCLUSIONS: According to this study, the EPFN yields better results in comparison with the GPFN, with relatively less complications rate, for the treatment of unstable reverse oblique pertrochanteric fracture. In light of this results, we conclude that the EPFN might be as good as GPFN for the treatment of reverse oblique intertrochanteric fractures. LEVEL OF EVIDENCE: Level III retrospective study. The local institutional review board of the Tel Aviv Medical Center approved this study and all the surgeries were done exclusively in this institution.

INTRODUCTION: Femoral neck fractures (FNF) have been declared to be a worldwide epidemic, as their number is expected to surpass 6 million by the year 2050, with more than 7,000 cases per year in Israel. FNF are more common in patients older than 65 years, and are expected to become even more common as the population ages. Like in many other medical conditions, treatment must be adapted for the unique features of this population. In this report, we sought to review the extent of femoral neck fractures in the elderly and the accompanied clinical outcomes and economic implications. As this population constitutes a major part of the patients suffering from femoral neck fractures, and tend to suffer from a higher rate morbidity and mortality, the orthopedic surgeon must meticulously choose the appropriate treatment, in a relatively short timeframe of up to 24-48 hours. In order to do so, further high-quality research examining the clinical outcomes according to the treatment chosen in this special population is needed.

BACKGROUND: Traumatic spinal injuries can be life-threatening conditions. Despite numerous epidemiological studies, reports on specific spinal regions affected are lacking. HYPOTHESIS: We hypothesized that fractures at specific regions, such as the cervical spine (including the axis segment), have been affected to a greater degree. We also hypothesized that advanced age may be a significant contributing factor. OBJECTIVE: To longitudinally analyze trend of spine fractures and specific fracture subtypes. STUDY DESIGN: Longitudinal trend analysis of discharged patient state database. PATIENT SAMPLE: Discharged patient's data from 15 years (2003-2017) METHODS: We retrieved pertinent ICD-9 and 10 codes depicting fractures involving the entire spine and specific subtypes. To assess possible association with age, we analyzed the trend of the average age in patients discharged with and without spinal fractures as well as in specific fracture subtypes. Similar analysis was performed for other common fragility fractures. FDA device/drug status: The manuscript submitted does not contain information about medical device(s) or drug(s). RESULTS: We found that within 15 years, the overall proportion of spinal fractures has increased by 64% (from 0.47 to 0.77% of all discharged patients) with the greatest increase noted in fractures of the cervical spine (123%) and specifically of the second cervical vertebra (84%). Age was found to have increased more in patients with spinal fractures than in the general discharged population. Surprisingly, other non-spinal fractures among patients above 60 remained relatively stable, demonstrating a spine-specific effect. CONCLUSIONS: Our findings confirm a recent increase in all spinal fractures and in the cervical and sacral regions in particular. Advanced age may be an important underlying factor.

STUDY DESIGN: A retrospective cohort study. PURPOSE: This study aims to examine the effect of tranexamic acid (TXA) on postoperative wound healing in spine surgery. OVERVIEW OF LITERATURE: TXA (Cyklokapron, Hexakapron) is a widely used anti-fibrinolytic drug that is shown to be effective in mitigating hemorrhage during and after surgery by competitively blocking plasminogen in fibrinolytic cascade. Plasminogen also plays a role in inflammatory and infectious diseases. The modulation of this role by TXA may influence the development of postoperative infectious complications. METHODS: We collected and reviewed the charts of 110 patients who underwent spine surgery at our academic center. We used multivariate regression analysis to assess the factors affecting surgical site infection (SSI). RESULTS: Of the 110 patients included in this study, 21 patients (19%) were categorized as having postoperative wound complications, 16 patients (14%) had deep or superficial wound infection, and five patients (4%) had wound dehiscence. Patients with a higher surgical invasiveness index score, longer surgeries, and older patients were found to be at risk for wound complications. TXA was determined not to be a direct risk factor for wound healing complications and SSIs. CONCLUSIONS: We found no risk of wound healing complications and SSI directly attributable to preoperative and intraoperative treatment with TXA in spine surgeries.
RESUMO
PURPOSE: To determine if boney morphology influences the anatomic location of hip fractures in elderly patients. METHODS: All patients with hip fractures between 2008 and 2012 who had hip radiographs taken prior to the fracture were reviewed. Fractures were classified as intracapsular or extracapsular and hip morphology was measured on the pre-fracture x-rays. Hip morphology was determined by alpha angle, lateral central edge angle, acetabular index, neck-shaft angle, hip axis length, femoral neck diameter, Tönnis classification for hip osteoarthritis (OA) and the presence of a crossover sign. RESULTS: 148 subjects (78.4% female, age 83.5 years) with proximal femur fractures were included. 44 patients (29.7%) had intracapsular fractures and 104 (70.3%) had extracapsular fractures. 48% of patients had previous hip fractures on the contralateral side and 74.6% had the same type of fracture bilaterally. The rates of bilateral intracapsular and extracapsular fractures were similar (33.7% vs. 40.9% respectively, p = 0.39). Extracapsular fractures had a statically significant higher neck-shaft angle, a shorter hip axis length, a narrower femoral neck diameter and a higher grade of Tönnis classification of OA (p = 0.04, 0.046, 0.03, 0.02 respectively). Acetabular coverage and the proximal femoral head-neck junction, which were evaluated by lateral centre-edge angle (LCEA), acetabular index and the presence of a crossover sign, did not correlate with fracture type. The alpha angle > 40° had a statistically significant higher likelihood for extracapsular fractures (p = 0.013). CONCLUSIONS: Acetabular coverage and proximal femoral head-neck junction morphology, were found to partially correlate with the location of hip fractures and do not fully elucidate fracture type susceptibility.

Capsulotomy is necessary to facilitate instrument manoeuvrability within the joint capsule in many arthroscopic hip surgical procedures. In cases where a clear indication for capsular closure does not exist, surgeon's preference and experience often determines capsular management. The purpose of this study was to assess the influence of capsular closure on clinical outcome scores and satisfaction in patients who underwent hip arthroscopy surgery for femoroacetabular impingement (FAI) and labral tear. Data were prospectively collected and retrospectively analysed for hip arthroscopy surgeries with a minimum 2 years follow-up. Patients with developmental dysplasia of the hip, previous back or hip surgeries, and degenerative changes to this hip and secondary gains were excluded. Demographic data, intraoperative findings and patient-reported outcome scores were recorded, including the Modified Harris Hip Score (MHHS) and Hip Outcome Score (HOS). A total of 29 and 35 patients were included in the non-closure and closure groups, respectively. The mean follow-up time was over 3 years for both groups. The mean pre-operative and post-operative HOS scores and MHHS scores did not significantly differ between groups (pre-operative HOS: 65.6 and 66.3, P = 0.898; post-operative HOS: 85.4 and 87.2, P = 0.718; pre-operative MHHS: 63.2 and 58.4, P = 0.223; post-operative MHHS: 85.7 and 88.7, P = 0.510). Overall patient satisfaction did not differ significantly between groups (non-closure 86.3%, closure group 88.6%; P = 0.672). Capsular closure did not significantly influence satisfaction or clinical outcome scores in patients who underwent arthroscopic hip surgery for FAI or labral tear.
RESUMO
BACKGROUND: Functional scores and radiographs are often used to assess function and predict development of osteoarthritis in patients with multi-fragmentary tibial plateau fractures (TPFs). Locomotion, which is the primary goal of fracture treatment, is rarely assessed. The objective of this study was to assess functional ability of patients after TPF fixation using spatio-temporal gait analysis (STGA), and to compare STGA variables with self-reported functional scores and preoperative fracture characteristics. METHODS: Preoperative CT scans of 21 patients with complete articular multi-fragmentary TPFs were evaluated for number of fragments, maximum gap between the fragments and maximum articular depression. All patients underwent STGA (velocity, cadence, step length of the affected and the unaffected leg, single-limb support by the affected and the unaffected leg, and double-leg support) and filled the Knee Society Score and the Short Form-12 questionnaires on average 3â¯years (SDâ¯=â¯1.56, range, 2-5.8) post-injury. FINDINGS: Step length and single-limb support time of the affected leg were shorter compared to the unaffected leg (pâ¯=â¯0.02 and pâ¯=â¯0.007, respectively). Number of fracture fragments correlated with cadence (Râ¯=â¯-0.461, pâ¯=â¯0.04) and velocity (Râ¯=â¯-0.447, pâ¯=â¯0.04). INTERPRETATION: Given that both higher fracture comminution and deformity on the one hand and the above gait parameter alterations on the other hand are associated with knee osteoarthritis, STGA may be used for routine postoperative evaluation of patients after TPF fixation.

PURPOSE: This study was designed to compare the results of clavicle fracture open reduction internal fixation (ORIF) with standard horizontal incision versus vertical incision. METHODS: ORIF surgery performed between October 2012 and August 2016 was included. The surgical approach was chosen according to surgeon preference as vertical or horizontal. Functional outcomes, fracture union, complications, scar appearance, skin irritation, and denervation around the scar were assessed at a minimum follow-up of three months. RESULTS: Thirty-eight patients, age 39 ± 12 years, were operated upon, 22 through vertical incisions and 16 through horizontal incisions. There were no significant group differences in functional scores, fracture union, or complications. Two patients in the vertical incision group had a post-operative haematoma. The scar length was significantly shorter when a vertical incision was used (6.75 ± 1.25 cm vs 8.9 ± 2.3 cm, P = 0.001). The typical distribution of hypoesthetic skin area distal and lateral to the scar represented iatrogenic damage to the supraclavicular nerves and was found in 66% of patients. The mean hypoesthetic surface area was smaller in the vertical incision group (38 ± 29 cm2 vs 48 ± 28 cm2, P = non-significant). CONCLUSION: Vertical incision results in shorter scars but may be associated with increased incidence of haematomas. Meticulous closure of the subcutaneous tissue is recommended.
