RESUMEN
INTRODUCTION: Self-reduction of a shoulder dislocation may reduce the time from injury to reduction and to the relief of patient discomfort. The purpose of this study was to assess adherence to earlier acquired self-reduction techniques during real-time recurrent shoulder dislocation. METHODS: A telephone survey was conducted among 58 patients previously taught shoulder self-reduction via an instructional video sent to their smartphones during a visit to the emergency department (ED) for the treatment of anterior shoulder dislocation. Participants were queried on recurrent dislocations, use of self-reduction methods, success rate, the effect that instruction in self-reduction had on their willingness to participate in recreational sports activities, on the decision to avoid surgery, and on the overall level of satisfaction with self-reduction methods. RESULTS: Forty-five patients (77.6%; average age 31.4±11.7 y, 10 females) were available for follow-up at an average 60.8±11.0 mo after the index visit to the ED. Eighteen of 23 patients (78.2%) who experienced a recurrent dislocation during the follow-up period attempted self-reduction, and 12 of them successfully achieved self-reduction. Sixteen patients (35.6%) reported that the knowledge in self-reduction increased their willingness to participate in recreational sports activities, whereas 4 (8.9%) patients reported that knowledge in self-reduction affected their decision not to undergo surgical stabilization. CONCLUSIONS: Individuals who sustain recurrent shoulder dislocations should be educated on shoulder self-reduction with the aims of minimizing discomfort, obviating referral to the ED, and motivating participation in recreational activities.

BACKGROUND: As advanced technology continues to evolve, incorporating robotics into surgical procedures has become imperative for precision and accuracy in preoperative planning. Nevertheless, the integration of three-dimensional (3D) imaging into these processes presents both financial considerations and potential patient safety concerns. This study aims to assess the accuracy of a novel 2D-to-3D knee reconstruction solution, RSIP XPlan.ai™ (RSIP Vision, Jerusalem, Israel), on preoperative total knee arthroplasty (TKA) patient anatomies. METHODS: Accuracy was calculated by measuring the Root Mean Square Error (RMSE) between X-ray-based 3D bone models generated by the algorithm and corresponding CT bone segmentations (distances of each mesh vertex to the closest vertex in the second mesh). The RMSE was computed globally for each bone, locally for eight clinically relevant bony landmark regions, and along simulated bone cut contours. In addition, the accuracies of three anatomical axes were assessed by comparing angular deviations to inter- and intra-observer baseline values. RESULTS: The global RMSE was 0.93 ± 0.25 mm for the femur and 0.88 ± 0.14 mm for the tibia. Local RMSE values for bony landmark regions were 0.51 ± 0.33 mm for the five femoral landmarks and 0.47 ± 0.17 mm for the three tibial landmarks. The RMSE along simulated cut contours was 0.75 ± 0.35 mm for the distal femur cut and 0.63 ± 0.27 mm for the proximal tibial cut. Anatomical axial average angular deviations were 1.89° for the trans epicondylar axis (with an inter- and intra-observer baseline of 1.43°), 1.78° for the posterior condylar axis (with a baseline of 1.71°), and 2.82° (with a baseline of 2.56°) for the medial-lateral transverse axis. CONCLUSIONS: The study findings demonstrate promising results regarding the accuracy of XPlan.ai™ in reconstructing 3D bone models from plain-film X-rays. The observed accuracy on real-world TKA patient anatomies in anatomically relevant regions, including bony landmarks, cut contours, and axes, suggests the potential utility of this method in various clinical scenarios. Further validation studies on larger cohorts are warranted to fully assess the reliability and generalizability of our results. Nonetheless, our findings lay the groundwork for potential advancements in future robotic arthroplasty technologies, with XPlan.ai™ offering a promising alternative to conventional CT scans in certain clinical contexts.
RESUMEN
BACKGROUND: Magnetically controlled growing rod (MCGR) treatment for early-onset scoliosis (EOS) has become a widely utilized method of deformity control, but long-term follow-up reports are sparse. We evaluated the outcomes of a large group of consecutive pediatric patients diagnosed with EOS who were treated by MCGR to the endpoint of definitive spinal fusion in a single center. We hypothesized that lessons learned from treating a large volume of MCGR patients would lower the complication rate in comparison to what was previously reported by other studies. METHODS: The records of 48 EOS patients with varied etiologies who were treated by MCGR between 2012 and 2022 and reached the end of treatment were analyzed retrospectively for baseline and final radiographic measurements and surgery-related complications. RESULTS: The mean percent of improvement in the major coronal deformity was 51.7±25.0% and the mean T1 to T12 total growth was 52.9±21.9 mm. The total complication rate was 22.9% of which 12.5% required a single unplanned surgery, 6.3% required multiple unplanned surgeries, and 4% did not require any unplanned surgery. CONCLUSION: MCGR treatment provides adequate control of EOS, enabling satisfactory growth of the thoracic spine. The complication rate in a single large volume center is moderate. LEVEL OF EVIDENCE: IV.

The surgical treatment for osteoid osteoma (OO) in the upper extremity is challenging due to the difficulty in locating the lesion and the crowding of sensitive structures within the anatomy. This study aimed to describe the outcomes of navigated minimally invasive radiofrequency ablation and those of navigated mini open-intralesional curettage in treating these lesions. Nineteen consecutive patients with OO in the upper limb who underwent navigated surgery were included. The average QuickDASH and Numeric Pain Rating Scale improved from 62.2 ± 23.7 to 11.7 ± 16.9 and from 8.1 ± 1.6 to 0.5 ± 1.8, respectively (p < .01 each) following the procedure. Two complications were recorded: one patient had persistent radial nerve palsy, and one patient had transient partial radial nerve weakness. In conclusion, navigation is an important tool in the surgical treatment of OO in the upper limb. A mini open approach to identify and protect neurovascular structures is recommended.

BACKGROUND: Although fibromyalgia is associated with poor outcomes following orthopedic surgeries, several studies show some benefit from surgical intervention and nevertheless recommend operative treatment when indicated. There is sparse evidence of the effect of fibromyalgia on the outcomes of shoulder surgery. The purpose of this study was to investigate the effect of fibromyalgia on patient-reported outcomes of arthroscopic rotator cuff repair (ARCR). METHODS: All patients with a confirmed diagnosis of fibromyalgia who underwent ARCR in one institution between 2010 and 2021 were included. Data retrieved from medical records included demographics, characteristics of the cuff tear and the surgical procedure, and preoperative and last follow-up (minimum 1 year) postoperative Disabilities of the Arm, Shoulder and Hand (DASH) score, Subjective Shoulder score (SSV), and Numeric Pain Rating Scale (NPRS). A matched controlled group of patients without fibromyalgia who had undergone ARCR was selected according to age, sex, and preoperative DASH, SSV, and NPRS scores. RESULTS: There were no significant differences in demographics, cuff tear and surgical procedure characteristics, and preoperative scores between the fibromyalgia and control groups. The fibromyalgia patients' postoperative scores for all 3 measurements showed significant improvement: SSV by 32.1 (P = 0.004), DASH by 20.3 (P = 0.016), and NPRS by 2.33 (P = 0.017). There were no significant differences in the postoperative DASH, SSV, and NPRS between the fibromyalgia and control groups. CONCLUSION: Fibromyalgia patients with rotator cuff tears who undergo ARCR do not have inferior patient-reported outcomes compared with non-fibromyalgia controls. Fibromyalgia should not be a considered a contraindication for ARCR. LEVEL OF EVIDENCE: III.

BACKGROUND: The surgical treatment for osteoid osteoma (OO) in the foot and ankle is challenging. It is difficult to locate the lesion and the anatomy is crowded by sensitive structures. The purpose of this study was to describe the outcomes of navigated mini open-intralesional curettage (NMIC) or navigated minimally invasive radiofrequency ablation (NMRFA) in treating these lesions. METHODS: All patients who underwent surgery for OO in the foot and ankle between 2015 and 2020 were included. O-arm navigation was used in All procedures. The choice of NMIC versus NMRFA was made by the surgeon according to the location of the lesion and its proximity to sensitive anatomic structures. RESULTS: Fourteen patients were included. Ten were operated by NMRFA and 4 by NMIC. All patients' symptoms related to OO resolved following a single procedure. Average AOFAS score increased by 18.7 (P < .001). Three patients had the following complications: pathologic fracture, superficial infection and transient deep peroneal nerve sensory loss. CONCLUSION: Navigated surgical treatment of OO in the foot and ankle is accurate, efficient and safe.

Background: Transtibial amputation (TTA) due to complications of diabetic foot infection (DFI) or peripheral vascular disease (PVD) is a high-risk procedure in fragile patients. The risks of reoperation, blood loss requiring blood transfusion, and mortality are high. The use of a tourniquet in this procedure is controversial and scarcely reported. Objective: this study aimed to compare the outcomes of TTAs with or without a tourniquet in a single tertiary medical center. Methods: We retrospectively identified all patients who had undergone TTA in our institution (1/2019-1/2020) and included only those who underwent the procedure due to complications of DFI or PVD (n = 69). The retrieved data included demographics, comorbidities, ASA score, the use of a tourniquet, operation duration, pre- and postoperative hemoglobin levels, administration of blood transfusions, hospitalization length, surgical site infection and 60-days reoperation and mortality rates. Results: TTA with a tourniquet was superior to TTA without a tourniquet in reducing the average operation length by 11 min (p = 0.05), the median postoperative hospitalization by 6 days (p = 0.04), and the use of blood transfusions (odds ratio [OR] = 0.176, 95% confidence interval [CI]: 0.031-0.996). Conclusions: Our findings demonstrated advantages in operative time, hospitalization length, and blood transfusion requirement for TTA with a tourniquet compared to TTA without a tourniquet.

Background: Primary bone sarcomas are associated with critically sized bone defects and require complete resection with negative margins. Recent advancements in health care have pioneered novel approaches such as the implementation of 3D surgical technologies. This study presents oncological and functional outcomes following tumor resections of long bones with the use of customized 3D-printed Patient Specific Instruments (PSIs). Methods: This single-center retrospective study is comprised of seventeen patients who underwent either intercalary (N = 12) or geographic (N = 5) resections with various reconstruction methods including allograft (N = 8), vascularized fibula (Capanna) (N = 7), and 3D printed customized titanium implants (N = 2), between the years 2016-2020. All patients were operated on with a 3D surgical workflow, including intraoperative PSIs, and were followed up postoperatively for at least 12 months (average 31.40 ± 12.13 months) to assess oncological and functional outcomes. Results: All patients demonstrated negative surgical margins, apart from one patient who had planned positive margins. Three patients suffered from short-term complications, and three patients underwent revision surgery due to graft non-union or pathological fracture. One patient suffered from local recurrence and underwent above-knee amputation. Three patients suffered from lung metastasis. MSTS at 12-month follow-up was 26.9.±5.87. Conclusion: Customized 3D-printed osteotomy PSIs provide surgeons with a novel tool for optimizing bone resection and reconstruction in long bones surgeries, thus minimizing overall tissue trauma and reducing the risk of damage to nervous and vascular structures. This study demonstrates that the use of PSIs has the potential to improve functional and oncological outcomes. We believe that this technique will become increasingly popular in the future as a widely applicable, highly accurate, cost-effective optimization tool.
RESUMEN
PURPOSE: The purpose of this study is to present the outcomes all patients with osteogenesis imperfecta (OI) who underwent cementless posterior spinal fusion for the treatment of severe spine deformity in our institution. METHODS: All patients with OI who underwent surgical correction of their spine deformity in our institution between 2003 and 2020 were enrolled. The collected data included demographics, operative and follow-up findings, medical history, bisphosphonate therapy, HGT protocol, pre- and post-HGT and postoperative scoliosis and kyphosis curve measurements, hospitalization length, complications, and revision surgeries. General treatment strategies included cessation of bisphosphonate therapy around the surgery, 30-day HGT protocol, titanium rods, cementless screw technique, and a high implant density policy. RESULTS: Eleven consecutive patients with OI who underwent surgery for spine deformity in our institution were identified. The mean age at surgery was 15.6 ± 2.3. Mean follow-up period was 6.6 ± 5.8 years. The mean pre- and postoperative scoliosis curves were 85.4 ± 19.3° and 43.1 ± 12.5°, respectively, representing a 49.5% correction rate. Five patients underwent HGT and achieved a mean correction of 27.6 ± 7.1° (31.6%) preoperatively. Implant density ratio was 1.5 (screw or hook/level). Mean postoperative hospitalization length was 5.9 ± 1.6 days. One patient had deep wound infection which resolved following treatment according to our protocol for surgical site infection, and one patient had skull penetration by one of the halo pins. CONCLUSION: Surgical treatment of severe spine deformity in OI patients with cementless posterior spinal fusion is safe and effective after applying a specific preoperative strategy.

BACKGROUND: The management of bone defects remains one of the major challenges surgeons are faced with in revision total knee arthroplasty (RTKA). Large and uncontained bone defects are traditionally managed with metaphyseal sleeves that facilitate osseointegration and have reported construct stability. While many studies have presented excellent short-term outcomes using metaphyseal sleeves, less is known on their performance in the longer term. The purpose of this study was to present our mid-term results of the metaphyseal sleeves used in patients undergoing RTKA. MATERIALS AND METHODS: Between January 2007 and January 2015, 30 patients underwent RTKA with the use of a CCKMB prosthesis combined with an osteointegrative sleeve. The main indications for RTKA were instability in 40% of the cases (n = 12), aseptic loosening in 30% (n = 9), infection in 26.7% (n = 8), and "other" in 3.3% (n = 1). The minimal follow-up time was 5 years and the mean follow-up time was 82.4 months (SD = 22.6). Clinical outcomes were assessed by Knee Society scores (KSS), range of motion and rate of re-operation. RESULTS: The mean Knee Society score increased significantly from 72.1 preoperatively to 90.0 postoperatively (p < 0.001). The cumulative incidence of re-operation in our study was 13.3% (n = 4). Our study reported no cases of aseptic loosening or mobile-bearing spin-out. Knee flexion to 90° and more was impossible in seven cases (23.3%) preoperatively and in one case (3.3%) postoperatively. CONCLUSION: Porous-coated metaphyseal sleeves demonstrated excellent rates of survivorship and radiographic ingrowth in the mid-term setting. However, further studies are required to assess their outcomes in the long-term.
RESUMEN
PURPOSE: Knee instability is one of the most common indications for having to undergo revision total knee arthroplasty (RTKA) and can be prevented with adequate implant selection and good surgical technique. Varus-valgus constrained implants (VVC) are indicated for cases of RTKA with absent ligament function in order to provide the necessary stability. While mobile-bearing articulations are thought to decrease the risk of aseptic loosening in comparison to their fixed-bearing counterparts, there is limited data on their outcomes. The purpose of our study is to present the clinical and radiological outcomes for patients undergoing an RTKA procedure with the mobile-bearing VVC implant. METHODS: Between January 2008 to January 2018, 93 patients underwent RTKA with the use of varus-valgus mobile-bearing (VVCMB) prosthesis. The main indications for RTKA were instability 38.7% (n = 36), aseptic loosening 31.2% (n = 29), infection in 26.9% (n = 25), and other 3.3%. The mean follow-up time was 56 months. Clinical outcomes were assessed by knee society scores, range of motion, and rate of re-operation. RESULTS: The mean knee society score increased significantly from 65.52 pre-operatively to 89.65 post-operatively (p < 0.001). The five year cumulative incidence of re-operation in our study was 7.53% (n = 7). Our study reported no cases of aseptic loosening or mobile-bearing spin-out. The number of flexion contractures decreased from n = 23 (24.7%) pre-operatively to n = 11 (11.8%) post-operatively (p < 0.05). CONCLUSION: The VVC mobile-bearing prosthesis demonstrated good clinical outcomes and mid-term survivorship in patients undergoing RTKA. Additional follow-up is required in the long term.

INTRODUCTION: Acetylsalicylic acid (aspirin) is a commonly prescribed medication, especially in the age group of individuals who undergo elective total hip arthroplasty (THA). Preoperative discontinuation of aspirin is believed to reduce intraoperative bleeding and other complications, but it may increase the risk of perioperative cardiovascular events. In this study we have sought to evaluate the safety of continuous aspirin treatment in patients undergoing elective THA. MATERIALS AND METHODS: This is a retrospective analysis of a consecutive cohort who underwent elective THA in a tertiary medical center between 2011 and 2018. The cohort was divided into two groups-one that received continuous preoperative aspirin treatment and one that did not. Blood loss, peri- and postoperative complications, readmissions, and short- and long-term mortality were compared between groups. RESULTS: Out of 757 consecutive patients (293 males, 464 females) who underwent elective primary THA, 552 were in the "non-aspirin" group and 205 were in the "aspirin" group and were not treated preoperative with other medication affecting hemostasis. Perioperative continuation of aspirin treatment did not significantly increase perioperative bleeding, as indicated by changes in hemoglobin levels (P = 0.72). There were no significant differences in short- and long-term mortality (P = 0.47 and P = 0.4, respectively) or other perioperative complications, such as readmission (P = 0.78), deep or superficial infection (P = 1 and P = 0.47, respectively), and cardiovascular events (none in both groups). CONCLUSION: Peri-operative continuation of aspirin treatment in patients undergoing elective primary THA did not increase perioperative complications or mortality compared to the non-aspirin-treated patients. The protective effects of aspirin from postoperative thrombotic and cardiovascular events are well documented. The current findings dispute the need to preoperatively withhold aspirin treatment in patients undergoing elective primary THA.

INTRODUCTION: Proximal humerus nails (PHN) are commonly used for the treatment of simple proximal humerus fractures, and have a reported malunion rate of about 10%. The surgeons who used PHN in one medical institution have noticed a high rate of fracture re-displacement in the early post-operative period. This study's aim is to evaluate the rate of secondary displacement and malunion of patients treated for two part proximal humerus fractures with an angle-stable PHN (MultiLoc), and to assess possible risk factors for this secondary displacement. METHODS: A retrospective study comprised of 25 consecutive patients with 2 part surgical neck or metaphysis displaced proximal humerus fracture, treated with PHN between the years 2014-2017. Results assessed included radiographic measures (neck-shaft angle) and clinical data: range of motion (ROM) and functional scores (Constant, DASH, SSV). A univariate regression analysis was used to assess possible risk factors for secondary displacement. RESULTS: Mean age was 66.6 (range 17-93), and mean follow up was 20 months (range 6-40). Mean neck shaft angle (NSA) changed from 139.1° post operatively to 122.6° at last follow up, with 6 patients (24%) having a NSA change larger than 20°. Two patients (8%) ended up with NSA less than 90°, defined as malunion. The deltoid tuberosity index was found to correlate with the degree of displacement (-0.41, p = 0.04). CONCLUSIONS: PHN for simple displaced proximal humerus fractures was associated with fair clinical results but an unacceptable rate secondary displacement. The deltoid tuberosity index was found to correlate with the degree of this secondary displacement.
RESUMEN
BACKGROUND: Surgical exposure of the Lisfranc joint complex is within close proximity to the deep peroneal nerve, which can be injured in this approach. Common clinical practice is to remove Lisfranc hardware at 3 to 4 months postoperatively. However, it is unknown if this provides a clinical benefit or risks injury to the deep peroneal nerve. The rate of nerve injury is currently unknown from the published literature. This study clarifies rates of neurological injury to the deep peroneal nerve during primary surgery and hardware removal. METHODS: This retrospective study was performed on all patients of a single surgeon from 2012 to 2018. Fixation was performed with locking plates or screws depending on the injury pattern. All patients who required open reduction and internal fixation routinely underwent hardware removal during this time. Neurological injury was assessed in a binary fashion (normal or abnormal) at 2, 6, and 12 weeks after the primary surgery and 2 and 12 weeks after hardware removal. McNemar's test was performed to compare the rates of injury. Patients were contacted at a minimum follow-up of 15 months (range, 15-87 months) to assess persistent nerve injury and satisfaction. Fifty-seven patients with an average age of 29.8 years were included in the final analysis; all had documentation at 3 months postsurgery. RESULTS: All patients had normal neurology before surgery. The rate of nerve injury for the primary surgery (11%) was significantly lower than the rate for patients with nerve injury following hardware removal (23%). However, the rate of spontaneous neurological recovery was low, with symptoms persisting in 5 of 6 patients between the primary operation and subsequent hardware removal. When these patients were excluded from the analysis, the rate of new nerve injury following hardware removal (15%) was not significantly different from the primary surgery rate. Seventy-one percent of nerve injuries persisted at the minimum 15-month final follow-up, with all patients with nerve injury being very or partially satisfied. CONCLUSION: The rate of deep peroneal nerve injury from primary Lisfranc fixation was 11%, and when routine hardware removal was planned the overall rate of nerve injury rose to 23%. This may be useful information during the patient consent process. LEVEL OF EVIDENCE: Level IV, case series.

OBJECTIVES: Previous observational research has shown that elderly patients with hip fractures who are operated early (within 48 hours from admission) benefit from less short- and long-term mortality compared to those operated later. The objective of this study was to present regulatory measures aimed at promotion of early hip fracture surgery and their effect on the rates of early surgery and on postoperative mortality. DESIGN: Retrospective cohort. SETTING: Single inner-city medical center. PARTICIPANTS: Elderly patients with hip fractures operated during three time periods: 2006 to 2009 (n = 1735, no intervention), 2010 to 2013 (n = 2104, first intervention, positive reinforcement), and 2014 to 2016 (n = 1538, second intervention, positive and negative reinforcement). INTERVENTION: Two regulatory measures were introduced consecutively: staff extra wages for afternoon operations (positive reinforcement) in 2010 and making early operation rates publicly available as the Ministry of Health Quality Care Indexes (negative reinforcement) in 2013. MEASUREMENTS: Percentage of early surgeries and mortality at 1 month and 1 year postoperatively. RESULTS: A total of 5377 patients (1595 men, 3782 women; mean age, 83.1 ± 7.2 years) underwent hip surgery between 2006 and 2016. The three study groups did not differ significantly in age on admission, sex, type of hip fracture (intracapsular or extracapsular), American Society of Anesthesiologists' score, mean hemoglobin on admission, and mean socioeconomic status. The percentage of operations performed within 48 hours was 55%, 65%, and 85%, respectively (P < .001). One-month mortality was 3.9%, 5.1%, and 5%, respectively (P > .05), and one-year mortality was 19.2%, 18.7%, and 19.6%, respectively (P > .05). CONCLUSIONS: Management pressure on the staff to expedite hip surgery and avoid negative publicity in conjunction with additional wages for afternoon surgeries was successful at promoting earlier hip surgery. Despite the substantial increase in the rates of early surgery, however, mortality rates were not affected. J Am Geriatr Soc 67:777-783, 2019.

INTRODUCTION: Direct oral anticoagulation agents (DOACs) are increasingly prescribed to older adults. Concerns for perioperative blood loss dictate cessation of anticoagulation treatment and postponement of surgery until the coagulation system returns to normal state. The goal of this study is to compare the estimates of perioperative blood loss and mortality between patients using DOACs and patients receiving no anticoagultaion, in order to challenge the existing policy and question the need for surgery deferral. MATERIALS AND METHODS: This is a retrospective cohort of patients (age > 65) with proximal hip fractures treated with either closed reduction internal fixation (CRIF, n = 1143; DOAC use n = 60) or hemiarthroplasty (HA, n = 571; DOAC use n = 29). Baseline patient characteristics included age, gender, ASA score, socioeconomic level, type of surgica#1: In general a l treatment, duration of surgery and time from admission to surgery. The effect of anticoagulant prescription on percentage of hemoglobin change, odds of receiving blood transfusions and one-month and one-year mortality was evaluated separately for CRIF and HA patients. RESULTS: Patients receiving DOACs had similar perioperative hemoglobin change, transfusion rates and mortality, compared to subjects without anticoagulants in both CRIF and HA cohorts. DOAC patients undergoing CRIF had a longer delay to surgery (40.2 ± 26.9 vs 31.2 ± 22.2, p = 0.003) and higher mortality rates at one year postoperatively (26.7% vs 16.1%, p = 0.015). CONCLUSIONS: DOAC use was not associated with an increased perioperative blood loss or mortality compared to controls. However, they had to wait longer for surgery, which itself was an independent predictor of mortality. It may be safe to shorten waiting time for surgery in patients using anticoagulation, with the goal to minimize surgery delay.

Methylphenidate (MP), a widely used and abused stimulant medication for ADHD, negatively affects bone mass. However, previous epidemiological studies demonstrated that MP is not associated with increased incidence of fractures in children, and may even have a protective effect due to behavior modification. This study aimed to investigate the association between MP and fracture risk in a retrospective cohort of healthy military recruits, aged 18-25, with at least 1 year of service between 2008 and 2017. Subjects were divided into five groups: subjects without ADHD; untreated subjects with ADHD; and subjects with ADHD and prescriptions of 1-90, 91-180, or 181+ tablets during the study period. The primary outcome was at least one fracture diagnosis during the study. Among 682,110 subjects (409,175 men [60%]), 50,999 (7.5%) had fractures. MP was used by 1,681 (0.4%) men and 2.828 (1%) women. The fracture rates in the no ADHD, untreated ADHD, ADHD 0-90, ADHD 91-180, and ADHD 181+ groups were 10.4%, 16.4%, 8.7%, 4.8% and 5.8% in men, and 3.6%, 7.1%, 4.6%, 4.4% and 3% in women, respectively. Multivariate regression analysis confirmed an inverse dose-response association between MP and fractures in men (p < 0.001). In women, untreated ADHD was associated with a significantly higher fracture risk, compared to healthy controls (OR = 1.82, p < 0.001). The study confirms previous literature and demonstrates an inverse dose-response association between MP and fracture risk in men. © 2018 Orthopaedic Research Society.

Shoeprints left at crime scenes are seldom perfect. Many prints are distorted or contaminated by various materials. Noisy background often contributes to vagueness on the shoeprints as well. Test impressions made from the suspect's shoes in the laboratory are considered a genuine replication of the shoe-sole. This naïve attitude is far from being correct. Consecutive test impressions made in the laboratory under strict similar conditions revealed differences among the exemplars of the same sole. Some of them are minor, but some are major, and can mislead the less experienced practitioners during the comparison process. This article focuses on the inherent within source variability between controlled shoeprints made from the same shoe, as it appears on the RACs. To describe and analyze this variability, repeated test impressions were prepared, and datasets were created. Several RACs were marked on each test impression, using an expert assisting software tool (developed in the authors' lab). The variance in repeated test impressions is demonstrated and possible sources are discussed. This variance should be considered when trying to establish the degree of matching between individual characteristics.
RESUMEN
OBJECTIVE: To compare the incidences of any cancer and specific types among patients with Parkinson's disease (PD) in a 10-yrs time window around diagnosis, to that of the general population. METHODS: We conducted a population-based, retrospective large-scale cohort study on 7125 newly diagnosed PD patients who had just initiated anti-parkinsonian medications between 1.1.2000 and 12.31.2012; all members of Maccabi Health Services (MHS), a large Israeli HMO. Cancer incidence during the same period was collected from MHS cancer-registry. Standardized-Incidence-Ratio (SIR) accounting for age, chronological-year and sex were calculated to compare cancer risks of PD patients to that of MHS population. RESULTS: The PD cohort (54% males) had a mean age at initiation of anti-parkinsonian medications of 71.2 ± 10.3years. In a time-window of 6.6 ± 3.4years before and 4.0 ± 3.9years after PD was first treated, 21% of the men and 15% of the women were diagnosed with incident-cancer. We found no-difference in any cancer risk for the PD cohort compared to the reference population: SIR = 0.99 (95%CI: 0.92-1.06) for males and 0.98 (95%CI: 0.89-1.07) for females. Risks for lung and colon cancers in the PD cohort were significantly lower for both sexes compared to the reference population. Risks for breast, central nervous system, kidney, leukemia, lymphoma, melanoma, ovarian, pancreatic, prostatic, rectal and thyroid were similar for the two populations. The SIRs did not differ between the sexes. CONCLUSIONS: We found no difference in the risk of any-type of cancer among PD patients compared to the general population, focusing on 10yrs time-window around the initiation of anti-parkinsonian medications.
