Knowledge, Attitude, and Practices Regarding Radiation and its Hazards Among Orthopaedic Surgeons in India: A Questionnaire-Based Study.

Introduction: Orthopaedic surgeons are among the most frequent users of radiation and are often exposed to X-Ray radiation regularly. There is an overall unsatisfactory level of knowledge, attitude, and practices regarding the same among surgeons. This study aimed to assess the practices among orthopaedic surgeons regarding radiation and its hazards in India. Methodology: This questionnaire-based survey was conducted between March and September 2022. The questionnaire broadly assessed the knowledge, awareness, and practices among orthopaedic surgeons regularly exposed to X-ray radiation. The questionnaire consisted of objective and Likert scale questions which were distributed to the respondents electronically using publicly available contact information. A qualitative review of interpretations obtained from the responses and available evidence in the literature was then performed. Results: The response rate for the survey was 36.4%. 65.9% reported using trunk protection all the time during procedures. 57.1% of respondents reported not using thyroid protection during procedures. 92.3% reported not using protective goggles and 100% did not use appropriate gloves. 76.9% were not issued dosimeters, and only 5.5% of those who had been issued one wore it during radiation procedures. 58.2% reported having a dedicated employee to operate the machine. 86.8% of respondents did not have formal training and 81.3% were not aware of institutes offering formal training. Conclusion: There is very high compliance with the use of protection aprons among the respondents however, the use of other apparel like thyroid shields, protection goggles and gloves was poor. The awareness regarding radiation exposure was also poor as most respondents were not issued dosimeters, however, those issued with one were well aware of their exposure. It is imperative to prioritize both surgeons' and patients' safety where radiation exposure is concerned.

Management of tibial plateau fractures: a fresh review.

Tibial plateau fractures are complex injuries which carry significant morbidity and economic burden. They can present complex geometry depending upon the direction of the force and position of the limb and are often associated with significant soft-tissue injury. While the goals of adequate reduction, stable fixation, and early mobilization remain unchanged, the management of these injuries can be challenging even to experienced orthopaedic surgeons. Lacking consensus, this review aims to provide a summary of current state of orthopaedic practice in the face of tibial plateau fractures. A PubMed search for relevant recent articles as well as a reading of classical articles on tibial plateau fractures was carried out. The focus remained on articles concerned with management modalities and recent advances. A review of some classification systems was also done and included. A great majority of these fractures need operative fixation while respecting the soft tissues. Numerous methods have been reported in the literature including but not limited to plates, screws, external fixators, arthroscopy assisted methods, balloon-cement tibioplasty, or a combination thereof. There is a shortage of randomized controlled trials comparing various operative methods. This article provides a review of various techniques and latest advances made in the management of tibial plateau fractures. The key to achieving optimal functional outcome is using a tailored approach to the individual patient accounting for factors related to the injury pattern, type of host, surgical skills and experience, and local availability of implant devices while taking care of soft tissue. While there is no gold standard, a staged procedure is recommended with early spanning and definitive fixation at later stage by any appropriate methods while respecting the soft tissue, achieving anatomical reduction and adequate fixation and, early rehabilitation.

K-Wire-Based External Fixator for Management of Salter-Harris Type-II Distal Femur Physeal Injury.

We present a case of a 16-year-old male with a Salter-Harris type II physeal slip of the distal femur managed with closed reduction and K wire and clamp-based external fixator. Knee range of motion exercises were initiated after one week. The union was observed at 10 weeks, and implant removal was done on an outpatient basis. At one year follow-up, the patient had good clinical and radiological outcomes. The K-wire-based external fixator frame is an effective fixation method for distal femur physeal slips in older children, providing favorable radiological and functional outcomes.

K Wires or Cannulated Screws for Fixation of Lateral Condyle Fractures in Children: A Systematic Review of Comparative Studies.

Introduction: Lateral condyle fractures in children have been typically been treated operatively using Kirschner wires (K wire) or cannulated screws (CCS); however, a definitive choice of implant remains a matter of debate. This systematic review aims to determine if union and functional outcomes of these fractures are better with screw fixation. Methodology: A search of PubMed, Medline, Cochrane, and Google scholar was performed in March 2021. The results were screened by title and abstract, and relevance and a quality assessment of the data were performed for the articles meeting the inclusion criteria. Articles comparing radiological and functional outcomes of lateral condyle fractures treated with K wires or screws were included for examination. Articles were excluded if they did not compare outcomes of K wires and CCS together, or were in a language other than English, technical notes, case reports, and articles, which describe the use of fixation methods other than K wire or CCS as well as biomechanical studies were also excluded. Risk of bias and quality assessment of included articles were also done. Results: Seven clinical studies were included. 44.4% (n = 4) were retrospective review of records with level III evidence (77.7%, n = 7). Only two included articles had good-quality assessment scores. Union was reported in 85.7% % in K wire group and 99.6% in CCS group. Functional outcomes were not statistically significant between the two groups. Conclusion: Using screws to fix lateral condyle provides better union; however, there is no difference in the functional outcomes and complication rate between the two. Using screws or buried K wires adds the burden of an additional procedure for removal.

Metallosis and Nonunion: A Case Series and Literature Review.

Metallosis, defined as the presence of free metal particles in the tissue, including bone and soft tissue, is a rare phenomenon seen in orthopedic practice. It is more commonly seen in arthroplasty surgeries, but its occurrence in the presence of other metal implants is also well recognized. Multiple hypotheses are suggested to explain the genesis of metallosis, but it is traditionally believed that abnormal contact between the metal surfaces leads to abrasive wear causing the release of metal particles into the surrounding tissue eliciting foreign body reactions from the body's immune system. The consequences can be local effects, which can be asymptomatic soft tissue lesions, or lead to significant osteolysis, tissue necrosis, joint effusion, and large soft tissue masses, causing secondary pathological effects. The systemic distribution of these metal particles can also contribute to the clinical picture. The literature contains multiple case reports of metallosis following arthroplasty surgeries, but there is limited information on metallosis resulting from osteosynthesis of fractures. In this review, we are presenting our experience with a few patients who developed nonunion following the index surgeries and on revision were found to have metallosis as well. It is difficult to postulate whether metallosis was contributory to the nonunion or the other way around or whether the occurrence of nonunion in face of metallosis was a pure coincidence. Additionally, one of our patients had a positive intraoperative culture, further complicating the picture. In addition to the case series, we present a succinct review of the literature on metallosis found in previous studies.

Patient Preferences Regarding Telemedicine to In-person Consultation: A Questionnaire-Based Survey.

Introduction: Telemedicine has been evolving over the last two decades; however, with the advent of the COVID 19 pandemic, its utility and acceptance have drastically increased. Most studies report increasing acceptability and satisfaction rates. This study aimed to assess patient preferences regarding telemedicine to in-person consultations and to attempt to assess the factors driving these preferences. Material and Methods: A questionnaire-based cross-sectional study was conducted for patients who had both teleconsultation and in-person consultation in the orthopedic outpatient. After obtaining consent to participate in the study, the patients were divided into broad clinical categories and responses were recorded regarding the treatment of illness by the doctor and opinions regarding telemedicine. Most questions were in yes/no or a Likert-based questionnaire. Mean, median, percentage and proportions were used for statistical analysis of the data. Results: The study group included 264 patients, with the majority with fractures and dislocations. Most patients (55.7%) were comfortable using the software for teleconsultation, and half the respondents found telemedicine convenient. A large percentage of the study group preferred in-person consultation to teleconsultation (58.7%), and the primary reasons for discontinuing teleconsultation were dissatisfaction during the interaction with the doctor and poor connectivity to telecommunication networks. Conclusion: Telecommunication has high acceptance and satisfaction, but many factors limit its acceptance in developing countries.

Effectiveness of Calcium Sulfate and Hydroxyapatite Composite in Collapse Prevention in Osteonecrosis of Femoral Head.

Introduction Calcium-sulfate-hydroxyapatite bioceramics have been widely used as void fillers in bone. However, their effectiveness as void fillers in core decompression for osteonecrosis of the femoral head (ONFH) in preventing femoral head collapse prevention has limited evidence. The current study investigates the effectiveness of calcium-sulfate-hydroxyapatite bioceramics as a void filler in the core decompression procedure for ONFH. Methods We retrospectively reviewed the clinical and radiological records of ONFH patients that underwent core-decompression using either autologous iliac crest cancellous bone graft or calcium-sulfate-hydroxyapatite bioceramic paste as void fillers with at least one-year follow-up. The primary outcome of this study was the radiological progression of collapse in the last available standard anteroposterior (AP) radiographs of the hip. The collapse progression was compared between the two groups based on void fillers. Results This study included patient records with 44 hip joints that underwent core decompression. There were five female and 33 male patients. The mean age was 29.1±6.3 years. The mean follow-up duration was 21.4±3.4 months. No significant differences in collapse progression were observed between the two groups based on void fillers. Conclusion The use of calcium-sulfate-hydroxyapatite as a void filler in core decompress for ONFH is not superior to the autologous cancellous bone in terms of collapse prevention and mechanical support. Further modifications in the core decompression techniques and well-planned prospective studies would help establish sound recommendations.

Pubic Symphysis Osteomyelitis after Bilateral Laproscopic Hernia Repair: A Case Report and Review of Literature.

Introduction: Pubic symphysis osteomyelitis is a rare complication of hernia repair, it is easily mistaken for osteitis pubis (OP) which can lead to a significant delay in diagnosis and prolonged pain for the patient. Case Report: We present the case of a 41-year-old male who presented with complaints of diffuse low back pain, perineal pain for 8 weeks after bilateral laparoscopic hernia repair. The patient was initially considered to have OP and managed however pain did not relieve with treatment. There was tenderness in the ischial tuberosity only. At the time of presentation, X-ray revealed areas of erosion and sclerosis in the pubis with increased inflammatory markers. Magnetic resonance imaging showed an altered marrow signal in the pubic symphysis, edema in the gluteus maximus on the right side, and collection in the peri-vesical space. The patient was started on oral antibiotics for 6 weeks and clinicoradiological improvement was noted. Conclusion: Pubic osteomyelitis and OP show similar clinical presentations with contrasting treatments. Early identification and initiation of appropriate treatment can decrease morbidity and improve outcomes.

Prediction of quadruple hamstring graft diameter for anterior cruciate ligament reconstruction by anthropometric measurements.

BACKGROUND: The literature is scanty regarding the anthropometric predictors on the diameter of quadruple hamstring graft obtained in anterior cruciate ligament (ACL) reconstruction in Indian population. Minimum diameter of the graft for ACL reconstruction should be >7 mm to preclude failure. The objective of this study was to assess the prediction of the hamstring graft diameter by several anthropometric parameters including age, thigh circumference, weight, height and body mass index (BMI). MATERIALS AND METHODS: 46 consecutive patients who had undergone ACL reconstruction by the same surgeon using quadruple hamstring grafts were evaluated. The age, thigh circumference of the normal side, height, weight and BMI were recorded preoperatively and Pearson correlation was done using these parameters with graft diameter measured intraoperatively. Regression analysis in a stepwise manner was undertaken to assess the influence of individual anthropometric parameters on the graft diameter. RESULTS: There were 44 males and 2 females. Mean age was 29.4 years, mean height was 172.6 cm, mean weight was 70.9 kg, mean BMI was 23.8 kg/m(2), mean thigh circumference was 47.1 cm and mean graft diameter was 7.9 mm. There was a positive correlation individually between the thigh circumference and graft diameter obtained (r = 0.8, P < 0.01, n = 46), and between the height and graft diameter (r = 0.8, P < 0.01, n = 46). On the regression analysis thigh circumference and height were found to be significant predictors of graft diameter giving the following equation: Graft diameter (mm) = 0. 079 height (cm) +0.068 thigh circumference (cm) -9.031. CONCLUSION: Preoperatively using the above equation if graft diameter came out to be <7 mm then alternate options of graft material must be kept in mind in order to prevent failure.

Management of congenital talipes equinovarus by Ponseti technique: a clinical study.

The purpose of this study was to evaluate the early results of treatment of idiopathic congenital talipes equinovarus (CTEV) by the Ponseti method and compare the results with those of other manipulation techniques and surgical treatment reported in the literature. A total of 100 patients with 156 clubfeet (80 males, 20 females), were treated for idiopathic CTEV by the Ponseti method. The average age at presentation was 4.5 months. Scoring of each foot was done according to the Pirani score. Photographs showing the deformity and podograms were taken to have an objective record against which the results were compared. The mean total Pirani score at the start of treatment was 4.26 and mean foot print angle (FPA) was 14.2 degrees. Post correction, there was a significant difference (P < .001, z = 18.638) in the mean FPA. There was also a statistically significant difference between the pre- and postcorrection Pirani scores (P < .001, z = 55.427). In 95% of the patients correction of the deformity was achieved. The Ponseti technique is based on sound understanding of the pathoanatomy of clubfoot. The good results obtained by the Ponseti technique show that posteromedial soft tissue release may no longer be required for most cases of idiopathic CTEV.
