Before the advent of computed tomography, occipital condyle injuries were solely a postmortem diagnosis. Nowadays, CT is well established in the diagnostic workflow of trauma management, allowing accurate planning and proper treatment. Anderson and Montesano as well Tuli developed radiologic classifications, each based on a small number of cases, in regards to the stability of the lesion and also provided treatment recommendations. In this case study we present a 24-year-old man suffering massive trauma to the head and thorax from a agricultural vehicle accident, leading to a displaced avulsion fracture of the right occipital condyle with high atlanto-occipital instability (Anderson Montesano type III). However, the patient did not develop any neurological deficit. Within the scope of the damage control polytrauma algorithm, the atlanto-occipital instability was initially stabilized in a HALO fixator.

The fixation construct spanned from the occiput to C3 in order to achieve a high primary stability. At 3-months follow-up, CT scans showed bony healing of the right condyle in an unchanged displaced position and a successful posterior fusion of C0/C1. After one year, a complete implant removal was done.

Purpose: the goal of this paper is to share our experience with the use of mega knee-prosthesis as a treatment option for complex DFF in the elderly patient and do a review the literature. Methods: we operated 4 patients with complex DFF using a mega knee-prosthesis. All patients were operated by one senior surgeon. No patients were lost at follow-up. One patient died 7 months after the surgery from flu. All patient were female and the average age at the time of the surgery was 79, 5. Clinical outcomes were measured through the WOMAC, Oxford knee score and pain NRS. Post-operative autonomy was measured using the Parker score. A follow-up radiographic analysis was performed independently by the surgeon and a radiologist. Results: At an average follow-up of 2,3 years (range, 0,6 to 4,2 years), the average Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) was 17,25 (range, 7 to 37), the average Oxford knee score was 35,25 (range, 25 to 41) and the average pain Numerical Rating Scale (NRS) was 0,5 (range, 0 to 1). Conclusion: The use of cemented knee mega-prosthesis for complex intra-articular distal femoral fractures is a viable treatment option in elderly patient with osteoporotic bone as it allows immediate full weight bearing and a rapid return to pre-operative functional status.
目的:本文的目的是分享我们使用巨型膝关节假体作为老年患者复杂DFF的治疗选择的经验，并对文献进行回顾。方法:采用大型膝关节假体对4例复杂DFF患者进行手术治疗。所有患者均由一名资深外科医生进行手术。随访期间无患者丢失。一名患者在手术后7个月死于流感。所有患者均为女性，手术时平均年龄为79.5岁。临床结果通过WOMAC、牛津膝关节评分和疼痛NRS进行测量。术后自主性采用Parker评分。后续放射学分析由外科医生和放射科医生独立进行。结果:平均随访2,3年(范围，0,6至4,2年)，Western Ontario and McMaster Universities Osteoarthritis index (WOMAC)平均为17,25(范围，7至37)，Oxford膝关节评分平均为35,25(范围，25至41)，pain Numerical Rating Scale (NRS)平均为0,5(范围，0至1)。使用骨水泥假体治疗复杂的股骨远端关节内骨折是老年骨质疏松患者的一种可行的治疗选择，因为它可以立即完全负重并快速恢复到术前功能状态。

Introduction: The purpose of this study was to explore the geographic distribution of pediatric orthopaedic surgeons (POS) in the US as an accurate assessment of pediatric orthopaedic surgical care. Methods: A list of all POS in the US was compiled using publicly available information from the Pediatric Orthopaedic Society of North America (POSNA). Name, practice location, and other contact information were recorded for a total of 1,188 surgeons. Surgeons were sorted into congressional districts (CDs). Using Dr. Richard Cooper’s Trend Model and projections for the demand of orthopaedic surgeons in 2020, each state and CD was classified as having optimal, suboptimal, and greater-than-optimal numbers of POS. Results: The most POS were in California, Texas, Florida, and New York and the least were in Wyoming and Montana. The median number of POS per state was 23 (range: 0-134). The median number of POS per CD was 2 (range: 0-38). Out of a total number of 435 CDs in the US, there were 187 CDs that had 0 POS. Furthermore, all 435 CDs had suboptimal numbers of POS. Discussion and Conclusion: Currently, there is no surgeon: population ratio standard for POS specifically. Furthermore, numbers generated about orthopaedics in general are based on national figures and do not take into account local demographic, economic, and physician practice pattern variations that can cause suggested ratios to differ. However, the data generated from this study suggests that POS are not evenly distributed throughout the US and many areas are not optimally served.

Although young adulthood is often characterized by social and intellectual development and multiple transitions, college-aged individuals are also routinely exposed to situations that place them at high risk of mental health disorders. For college student-athletes, the pressures of academics, paired with the demands of a college athletic program, certainly have the potential to increase the risk of psychiatric conditions. This article will assist the clinician in understanding the unique challenges faced by the college athlete, recognize the importance of screening college athletes for mental health concerns, and appreciate unique treatment considerations.

Background: Hamstring tendon autografts, for ACL (anterior cruciate ligament) reconstruction, have demonstrated a higher re-rupture rates when graft diameter of <8 mm is chosen. In the event that an autograft yield a graft diameter <8 mm, augmentation with allograft creates a hybrid graft with increased diameter. Clinical outcomes of this hybrid graft have yet to be established. Purpose: To assess clinical outcomes and failure rates of an adult population who undergo augmentation with allograft compared to patients with hamstring autograft alone. Methods: A retrospective chart review of primary ACL reconstructions performed by 4 sports fellowship trained surgeons at a single institution between 2010-2016 identified 23 patients with hamstring autografts and allograft augmentation. A comparison group of 23 patients consisted of patients who underwent ACL reconstruction with hamstring autograft of >8 mm diameter was then selected. The comparison group was matched based on age within 3 years. Graft failure was defined as revision ACL reconstruction or evidence of graft failure on clinical exam (no end point on lachman or pivot shift) or MRI evidence of retear. International Knee Documentation Committee (IKDC), Marx Activity, and Knee injury Osteoarthritis and Outcome (KOOS) scores were obtained. Patients were contacted to obtain information regarding outcome scores, revision procedures, return to sport, and complications. A minimum follow up time was set at 12 months. Results: Forty-six patients met criteria for inclusion in this study and had follow up data. The hybrid group had a total of 23 patients consisting of 7 men and 16 women with an average age of 31 years (Range 17-51 years). The autograft group had a total of 23 patients consisting of 17 men and 6 women with an average age of 33.3 years (Range 15-48). The average follow-up between both groups was 31.5 months (range 12-63 months). The graft failure rate in the hybrid group was 8.7% (2 of 23 patients), while the autograft group demonstrated a graft failure rate of 4.3% (1 of 23 patients) (p=0.49). In the hybrid ACL group, the mean IKDC was 67.8 (CI 59.8-75.9) compared to 73.8 (CI 66.6-80.9) in the autograft group (p=0.26). The average KOOS scores for the hybrid group was 75.8 (CI 67.5-84.1) compared to 86.5 (CI 81.4-91.7) in the autograft group (p=0.03). Conclusions: In an adult population, allografts augmented hybrid ACL grafts showed no statistically significant difference compared to hamstring autograft in graft failure rates. The autograft ACL group demonstrated a higher KOOS score, though the IKDC was equivalent.

Aim: To Compare hamstring graft healing time after anterior cruciate ligament (ACL) reconstruction with the use of augmentation of platelet-rich plasma. Methods: 30 patients between age group of 18 to 40 years with complete ACL tear were randomly divided into two groups the control group in which only ACL reconstruction was done and second group in which acl reconstruction was performed along with augmentation with Platelet rich plasma. For the PRP group, 3 ml of PRP was obtained in the operation room and was injected into femoral tunnel just before after portal suture. MRI was obtained post operatively 3 month, 6 month and 9th month for both the groups. Graft healing time was defined as the time taken for the graft to reach ligamentization phase when the graft became hyperintense or was visualised similar to PCL or the remnant which was preserved during reconstruction. Results: Patients in PRP augmented group achieved ligamentization phase significantly earlier as compared to those in the control group, with mean time of 3.4 months as compared to 8.1 months in the control group. Conclusion: PRP helps in faster healing of the Hamstring graft. However further studies are required to correlate graft healing time with return to previous activity.

This paper proposes developing a wireless sensor for heartbeat and respiration rate monitoring for the sportsman. The developed wireless sensor, includes an accelerometer sensor, a processor and a transceiver which operates in Industrial, Scientific and Medical (ISM) band and the frequency of 2.54 to connect with a central node for transmitting the measured data. In order to evaluate the accuracy of the presented sensor, the different experiments are carried out on several volunteers and the resultant data are compared to a gold standard for respiration rate and also heartbeat as a reference. As the outcomes illustrate, the root means square error (RMSE) and the standard deviation of the error (SD) are calculated less than 2.8 and 1.43 beats per minutes as well as 1.01 and 0.85 breaths per minutes for the heartbeat and respiration rate, respectively. Therefore, the sensor can account a good alternative for cardiorespiratory system monitoring for sporty application, due to low-cost, portable and also availability.

Purpose: The purpose of this study was to prospectively evaluate the outcome of fixation of chevron osteotomy for treatment of hallux valgus deformity with bioabsorbable pins and stainless steel Kirschner wires. Materials and Methods: A total of 112 patients (134 feet) with mild-to-moderate hallux valgus deformity treated with either bioabsorbable pins or stainless steel K-wires were included in the study between February 2010 and June 2016. At follow-up, patients were objectively and subjectively assessed to estimate the first intermetatarsal angle (IMA), hallux valgus angle (HVA), time to bony union and complications. Results: There was no significant difference between the 2 groups in terms of radiographic findings and main clinical outcomes by use of American Orthopaedic Foot and Ankle Society (AOFAS) scores. Pin migration or prominence, however, was the predominant complication in patients with stainless steel K-wires. Conclusions: Bioabsorbable pins and stainless steel K-wires used for fixation of the chevron osteotomy for treatment of hallux valgus deformity are similarly successful up.

Materials and Methods: A total of 112 patients (134 feet) with mild-to-moderate hallux valgus deformity treated with either bioabsorbable pins or stainless steel K-wires were included in the study between February 2010 and June 2016. At follow-up, patients were objectively and subjectively assessed to estimate the first intermetatarsal angle (IMA), hallux valgus angle (HVA), time to bony union and complications. Results: There was no significant difference between the 2 groups in terms of radiographic findings and main clinical outcomes by use of American Orthopaedic Foot and Ankle Society (AOFAS) scores. Pin migration or prominence, however, was the predominant complication in patients with stainless steel K-wires. Conclusions: Bioabsorbable pins and stainless steel K-wires used for fixation of the chevron osteotomy for treatment of hallux valgus deformity are similarly successful up.","PeriodicalId":73881,"journal":{"name":"Journal of orthopaedics and sports medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69349978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
