The late—1 year after the knee injury—imaging assessment of the patient regarding radiograph images, CT scan, and MRI was misleading, misinterpreted, and failed to reveal this osteochondral fracture. The free osteochondral fragment was detected during diagnostic arthroscopy. Open reduction and fixation of the osteochondral fragment with bioabsorbable pins were done, and healing was achieved within an acceptable time. The patient's clinical and imaging examination with knee MRI, a year after the surgical treatment, was highly satisfactory. Fixation with bioabsorbable pins showed to be a worthwhile option in this case. The technique used was straightforward, with excellent short- and long-term results. Bioabsorbable pins may be used to restore successfully even an old, large osteochondral fracture in the immature skeleton.","PeriodicalId":145112,"journal":{"name":"JAAOS Global Research & Reviews","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128188459","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}

{"title":"Dialysis Dependence Is Associated With Significantly Increased Odds of Perioperative Adverse Events After Geriatric Hip Fracture Surgery Even After Controlling for Demographic Factors and Comorbidities","authors":"T. Ottesen, Alp Yurter, Blake N. Shultz, A. Galivanche, C. Zogg, P. Bovonratwet, L. Rubin, J. Grauer","doi":"10.5435/JAAOSGlobal-D-19-00086","DOIUrl":"https://doi.org/10.5435/JAAOSGlobal-D-19-00086","url":null,"abstract":"Introduction: Previous studies evaluating the risk of perioperative adverse events after hip fracture surgery for dialysis-dependent patients are either institutional cohort studies or limited by patient numbers. The current study uses the National Surgical Quality Improvement Program database's large national patient population and 30-day follow-up window to address these weaknesses. Methods: National Surgical Quality Improvement Program databases (2006 to 2016) were queried for patients aged 60 years or older who underwent hip fracture surgery. Differences in 30-day outcomes based on preoperative dialysis dependence were compared using risk-adjusted logistic regression and coarsened exact matching for adverse events, need for revision surgery, readmission, and mortality. The proportion of adverse events that occurred before versus after discharge was also assessed. Results: A total of 288 dialysis-dependent and 16,392 non–dialysis-dependent patients met the inclusion criteria. Matched populations controlling for demographic factors (ie, age, sex, body mass index, and functional status) and overall health (American Society of Anesthesiologists class) found dialysis-dependent patients to be associated with significantly greater odds of any adverse event (odds ratio [OR] = 1.90), major adverse event (OR = 1.77), and unplanned readmission (OR = 2.48). Increased odds of minor adverse event (OR = 1.05), return to the operating room (OR = 1.66), and death (OR = 1.42) within 30 postoperative days were also found but were not statistically significant. Discussion: Even after controlling for demographics and health status, geriatric dialysis patients undergoing surgery for hip fracture are at significantly greater odds of adverse outcomes. Because of increased risks for geriatric dialysis patients undergoing surgery for hip fracture, surgical caution, patient counseling, and heightened surveillance must be observed throughout the perioperative period for this fragile population. Furthermore, hospitals and physicians must take the increased risks associated with dialysis into account when considering bundled payment reimbursement strategies and resource allocation for hip fracture care.","PeriodicalId":145112,"journal":{"name":"JAAOS Global Research & Reviews","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126392772","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}

The use of a dynamic hip screw in this setting gave us a stable fixed-angle construct with compression across the fracture site, and the addition of a trochanteric side plate added to the stability. The dynamic compression plate with limited bone contact was used to neutralize the construct. This case describes the successful treatment of such an injury in a way not previously described in the literature with the intent of giving the orthopaedic traumatologist another method to approach this rare injury.","PeriodicalId":145112,"journal":{"name":"JAAOS Global Research & Reviews","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130227932","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}

Although there are many advantages to surgery in this position, there are also potential drawbacks and described complications including devastating neurologic outcomes. The etiology of these complications is postulated to be due to the gravitational effects of the seated position leading to cerebral hypoperfusion. We review the current literature on intraoperative cerebral monitoring and neurocognitive complications with shoulder surgery performed in the BCP. A previous systematic review estimated the incidence of neurocognitive complications after surgery in the BCP to be 0.004%. However, the true incidence is unknown and is likely much more common. Reports of neurologic complications have revealed a need for heightened vigilance, alternative anesthesia techniques, and improved monitoring. Methods for monitoring have included near-infrared spectroscopy, a measurement of cerebral oximetry shown to reliably detect cerebral hypoperfusion. In this literature review, we sought to update the incidence of intraoperative cerebral desaturation events (CDEs) to investigate the relationship of CDEs to neurocognitive complications and to review recent reported cases of neurocognitive complications. Existing literature suggest that accurate intraoperative monitoring of cerebral perfusion may improve patient safety.","PeriodicalId":145112,"journal":{"name":"JAAOS Global Research & Reviews","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130377974","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}

As concluded by the World Health Organization during the 2013 Global Forum on Human Resources for Health, an adequate healthcare workforce is mandatory to provide universal health coverage. Despite efforts to increase the numbers of healthcare workers, an extreme deficit in highly trained surgeons remains. Several options exist to provide training for surgeons in LMICs, including local training by local surgeons, sending local surgeons abroad for training, or local training by short-term or long-term visiting surgeons from high-income countries. This article further discusses the benefits and challenges of each option and reviews the 10-year outcomes of the Orthopaedic Surgery Residency Program at the CURE Kenya Hospital in Kijabe, Kenya. The program has graduated nine orthopaedic surgeons who are all practicing in Africa, five of which are full-time attending consultants in residency training programs. An additional eight residents are currently in the program. Sustainable orthopaedic training can be accomplished in LMICs as demonstrated by the ongoing success of the CURE Kenya Orthopaedic Surgery Residency Program. Additional efforts to expand and replicate this model may assist in providing improved access to high-quality universal healthcare in LMICs.","PeriodicalId":145112,"journal":{"name":"JAAOS Global Research & Reviews","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124631450","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}

Frequently, the cervicothoracic spine is involved. Only recently, the morbidity attributed to the spinal abnormalities has gained attention. Strategy and timing of spine surgery has become increasingly important in patients with OAVS. Here, we report a case of OAVS with characteristic vertebral cervical and thoracic involvement and its sequelae requiring multiple spinal procedures, further complexed by an unprecedented occult tethered cord syndrome, which was successfully treated by surgical detethering.

Despite its infrequent occurrence, AECS has devastating sequelae, including muscle necrosis and nerve injury. It is imperative to promptly evaluate for AECS in any patient who has notable pain and sensory changes in the context of recent physical activity because of the dire consequences of a missed diagnosis. A 34-year-old man presented to the emergency department with excruciating pain and diffuse paresthesias in his bilateral arms and forearms after participating in a push-up contest. He also had pain with passive stretch of his triceps. Because of these physical examination findings and uncontrollable pain, a clinical diagnosis of AECS was made and was managed with fasciotomies. Postoperatively, the patient's pain and paresthesias slowly resolved, and he was eventually able to return to work at full capacity as a construction worker. This example of AECS of bilateral upper extremities emphasizes that it is a condition that, although rare, is real and must be taken seriously. With appropriate clinical suspicion, a prompt diagnosis can be made, and potentially devastating consequences can be avoided.","PeriodicalId":145112,"journal":{"name":"JAAOS Global Research & Reviews","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133791835","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}

Patients are generally unaware of the prices of the services they use. Understanding the costs associated with surgical management of ankle arthritis is an important facet of patient care. The purposes of this study were to (1) determine the access to the surgical cost of total ankle arthroplasty (TAAs) and ankle arthrodesis and (2) the variability of the price between the two procedures. Methods: Fifty foot and ankle centers (25 academic, 25 private) that perform TAAs and ankle arthrodeses were contacted using a standardized patient script. The described patient was a 63-year-old man who had failed conservative treatment of ankle arthritis. Each institution was contacted up to three times in an attempt to obtain a full-bundled surgical quote for a TAA and an ankle arthrodesis. Results: Twenty-one centers (42%, 14 academic, 7 private) were able to provide a quote for a TAA and an ankle arthrodesis. The mean bundled price for a TAA was $50,332 (SD ± $25,744), with the mean academic and private center quote being $56,529 and $37,937, respectively. The mean bundled price for an ankle arthrodesis was $41,756 (SD ± $26,033), with the mean academic and private center quote being $48,116 and $29,037, respectively.

The purpose of this study was to identify an association between preoperative vitamin D (25D) levels and postoperative complications in arthroscopic RCR. Methods: From a national claims database, patients undergoing arthroscopic RCR with preoperative 25D levels were reviewed. Patients were stratified into 25D-sufficient (≥20 ng/dL) or 25D-deficient (<20 ng/dL) categories and examined for development of postoperative complications. Multivariate logistic regression was performed using age, sex, and Charlson Comorbidity Index (CCI) as covariates. From this, risk-adjusted odds ratios (ORs) were calculated comparing complications between the two groups. Results: One thousand eight hundred eighty-one patients with measured preoperative 25D levels were identified; 229 patients were 25D deficient (12.2%). After adjusting for age, sex, and Charlson Comorbidity Index, 25D-deficient patients had increased odds of revision RCR (OR 1.54, 95% confidence interval 1.21 to 1.97, P < 0.001) and stiffness requiring manipulation under anesthesia (OR 1.16, 95% confidence interval 1.03 to 2.03, P = 0.035).
