RESUMEN
PURPOSE: The aim of this systematic review and meta-analysis was to compare joint awareness in patients who underwent total hip arthroplasty (THA) via the anterior approach (AA) versus the posterior approach (PA). The hypothesis was that patients who underwent THA via AA would have better forgetfulness of the artificial joint. METHODS: A comprehensive search of major literature databases and bibliographic details was conducted to identify studies evaluating the forgotten joint score (FJS-12) in total hip arthroplasty (THA) patients operated through the anterior approach (AA) and posterior approach (PA). Out of 234 studies identified, seven studies met the inclusion criteria for review. The Newcastle-Ottawa Scale was used to evaluate the quality of evidence and the risk of bias in the included studies. The FJS-12 was evaluated at three months, one year, and beyond 2 years. RESULTS: The mean FJS-12 at > 2 years was 82.03 in the AA group and 80.32 in the PA group. The forest plot analysis (n = 819 patients) revealed no significant difference in FJS-12 score between these two approaches (MD 2.13, 95% CI [- 1.17, 5.42], p = 0.21; I2 = 60%). However, the joint awareness was significantly lesser in the AA group at 3 months (MD 12.56, 95% CI [9.58, 15.54], p < 0.00001, I2 = 0%) and 1 year (MD 9.55, 95% CI [7.85, 11.24], p < 0.0001, I2 = 0%). CONCLUSIONS: After analyzing the available literature, it was found that THA patients operated through the AA approach have significantly lower joint awareness than those operated through the PA approach in the first year of surgery. However, there is no significant difference in joint awareness between these two approaches after 2 years. LEVEL OF EVIDENCE: III.

PURPOSE: Unstable pelvic ring injury can result in a life-threatening situation and lead to long-term disability. Established classification systems, recently emerged resuscitative and treatment options as well as techniques, have facilitated expansion in how these injuries can be studied and managed. This study aims to access practice variation in the management of unstable pelvic injuries around the globe. METHODS: A standardized questionnaire including 15 questions was developed by experts from the SICOT trauma committee (Société Internationale de Chirurgie Orthopédique et de Traumatologie) and then distributed among members. The survey was conducted online for one month in 2022 with 358 trauma surgeons, encompassing responses from 80 countries (experience > 5 years = 79%). Topics in the questionnaire included surgical and interventional treatment strategies, classification, staging/reconstruction procedures, and preoperative imaging. Answer options for treatment strategies were ranked on a 4-point rating scale with following options: (1) always (A), (2) often (O), (3) seldom (S), and (4) never (N). Stratification was performed according to geographic regions (continents). RESULTS: The Young and Burgess (52%) and Tile/AO (47%) classification systems were commonly used. Preoperative three-dimensional (3D) computed tomography (CT) scans were utilized by 93% of respondents. Rescue screws (RS), C-clamps (CC), angioembolization (AE), and pelvic packing (PP) were observed to be rarely implemented in practice (A + O: RS = 24%, CC = 25%, AE = 21%, PP = 25%). External fixation was the most common method temporized fixation (A + O = 71%). Percutaneous screw fixation was the most common definitive fixation technique (A + O = 57%). In contrast, 3D navigation techniques were rarely utilized (A + O = 15%). Most standards in treatment of unstable pelvic ring injuries are implemented equally across the globe. The greatest differences were observed in augmented techniques to bleeding control, such as angioembolization and REBOA, more commonly used in Europe (both), North America (both), and Oceania (only angioembolization). CONCLUSION: The Young-Burgess and Tile/AO classifications are used approximately equally across the world. Initial non-invasive stabilization with binders and temporary external fixation are commonly utilized, while specific haemorrhage control techniques such as pelvic packing and angioembolization are rarely and REBOA almost never considered. The substantial regional differences' impact on outcomes needs to be further explored.

PURPOSE: Hip fractures among elderly patients are surgical emergencies. During COVID-19 pandemic time, many such patients could not be operated at early time because of the limitation of the medical resources, the risk of infection and redirection of medical attention to a severe infective health problem. METHODS: A search of electronic databases (PubMed, Medline, CINAHL, EMBASE and the Cochrane Central Register of Controlled Trials) with the keywords "COVID", "COVID-19â³, "SARS-COV-2", "Corona", "pandemic", "hip fracture", "trochanteric fracture" and "neck femur fracture" revealed 64 studies evaluating treatment of hip fracture in elderly patients during COVID-19 pandemic time. The 30-day mortality rate, inpatient mortality rate, critical care/special care need, readmission rate and complications rate in both groups were evaluated. Data were analyzed using Review Manager (RevMan) V.5.3. RESULTS: After screening, 7 studies were identified that described the mortality and morbidity in hip fractures in both COVID-19 infected (COVID-19 +) and non-infected (COVID-19 -) patients. There were significantly increased risks of 30-day mortality (32.23% COVID-19 + death vs. 8.85% COVID-19 - death) and inpatient mortality (29.33% vs. 2.62%) among COVID-19 + patients with odds ratio (OR) of 4.84 (95% CI: 3.13 - 7.47, p < 0.001) and 15.12 (95% CI: 6.12 - 37.37, p < 0.001), respectively. The COVID-19 + patients needed more critical care admission (OR = 5.08, 95% CI: 1.49 - 17.30, p < 0.009) and they remain admitted for a longer time in hospital (mean difference = 3.6, 95% CI: 1.74 - 5.45, p < 0.001); but there was no difference in readmission rate between these 2 groups. The risks of overall complications (OR = 17.22), development of pneumonia (OR = 22.25), and acute respiratory distress syndrome/acute respiratory failure (OR = 32.96) were significantly high among COVID-19 + patients compared to COVID-19 - patients. CONCLUSIONS: There are increased risks of the 30-day mortality, inpatient mortality and critical care admission among hip fracture patients who are COVID-19 +. The chances of developing pneumonia and acute respiratory failure are more in COVID-19 + patients than in COVID-19 â patients.

Background and Objectives: Pelvic nonunion and malunion have been documented as rare complications in pelvic fractures and literature describing these topics is severely limited. Articles dedicated solely to pelvic malunion are nearly nonexistent. We conducted a literature search with the goal of providing a summary of the definition, causes, treatment strategies, and outcomes of pelvic malunion correction. Materials and Methods: An initial review of the literature was performed using the PubMed, ScienceDirect, and Cochrane Database of Systematic Reviews databases. Search terms used were "malunion" AND "pelvic" OR "pelvis". Duplicate articles, non-English language articles without translations available and non-human subject studies were excluded. Results: Eleven original publications were found describing experiences with pelvic malunion. Seven of the articles were exclusively dedicated to the topic of pelvic fracture malunion, and only two reported on a series of patients treated for malunion with variably staged procedures. Most reports define pelvic pain as the main indication for surgical correction, along with gait disturbance, standing or sitting imbalance, and urinary or sexual dysfunction. Radiographically, vertical displacement of one to two centimeters and rotation of the hemipelvis of fifteen degrees or more have been described in defining malunion. No treatment algorithms exist, and each patient is treated with a unique work-up and operative plan due to the complexity of the problem. Only one series reported a patient satisfaction rate of 75% following malunion treatment. Conclusions: Pelvic malunion is a rare complication of pelvic ring injury and is seldom discussed in the literature. We found two small case series reporting exclusively on malunion treatment and complications. While some of the combination studies made the distinction in the diagnosis of malunion and nonunion, they rarely differentiated the treatment outcomes between the two categories. This paper describes pelvic malunion and highlights the need for more research into surgical outcomes of treatment specifically regarding functionality, patient satisfaction, and recurrence of preoperative symptoms.

PURPOSE: The purpose of this systematic review and meta-analysis is to evaluate the joint awareness after unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA). It was hypothesized that patients with UKA could better forget about their artificial joint in comparison to TKA. METHODS: A search of major literature databases and bibliographic details revealed 105 studies evaluating forgotten joint score in UKA and TKA. Seven studies found eligible for this review were assessed for risk of bias and quality of evidence using the Newcastle-Ottawa Scale. The forgotten joint score (FJS-12) was assessed at 6 months, 1 year, and 2 years. RESULTS: The mean FJS-12 at 2 years was 82.35 in the UKA group and 74.05 in the TKA group. Forest plot analysis of five studies (n = 930 patients) revealed a mean difference of 7.65 (95% CI: 3.72, 11.57, p = 0.0001; I2 = 89% with p < 0.0001) in FJS-12 at 2 years. Further sensitivity analysis lowered I2 heterogeneity to 31% after exclusion of the study by Blevin et al. (MD 5.88, 95%CI: 3.10, 8.66, p < 0.0001). A similar trend of differences in FJS-12 between the groups was observed at 6 months (MD 32.49, 95% CI: 17.55, 47.43, p < 0.0001) and at 1 year (MD 25.62, 95% CI: 4.26, 46.98, p = 0.02). CONCLUSIONS: UKA patients can better forget about their artificial joint compared to TKA patients. LEVEL OF EVIDENCE: III.

PURPOSE: To assess the reliability, validity and responsiveness of the Hindi version of the Knee Injury and Osteoarthritis Outcome Score (H-KOOS) in osteoarthritic knee. METHODS: Two hundred and fourteen patients of osteoarthritis knee (OA) between 40 and 80 years of age were evaluated with H-KOOS, Short form health survey (SF12v2) and the WHOQOL-BREF questionnaire. The H-KOOS was re-evaluated after 48 h in 125 patients to assess the test-retest reliability. For responsiveness, 40 patients were treated with the intra-articular hyaluronic acid injection, and the effect was assessed after 6 weeks. RESULTS: Most of the domains in H-KOOS did not show a ceiling effect. The floor values were observed in 3.75% of patients in sports/recreation function and 2.75% of patients in Quality of life (QoL). The test-retest reliability was excellent with the Intraclass-Correlation-Coefficient (ICC) ranging from 0.89 to 0.94. Internal consistency as assessed using Cronbach's alpha coefficient was acceptable for pain, activities of daily living (ADL) and sport/recreation function (range 0.86-0.93); however, symptoms and QoL had weak internal consistency. There were moderate to strong correlations (r = 0.35 to 0.6) between domains measuring similar constructs in H-KOOS, SF12v2 and WHOQOL-BREF indicating good convergent construct validity. The responsiveness as measured by the effect size (ES) and standardized response mean (SRM) was large for pain (ES 0.9, SRM 0.8), moderate for Sport/Rec (ES 0.66, SRM 0.2) and small for ADL, QoL and Symptoms subscales. CONCLUSION: The Hindi version KOOS is a valid, reliable and responsive measure to evaluate osteoarthritis knee with minimal ceiling and floor effects. LEVEL OF EVIDENCE: Prospective cohort study, level II.

PURPOSE: Total hip replacement (THR) is one of the most successful and cost-effective surgical procedures and remains the treatment of choice for long-term pain relief and restoration of function for patients with diseased or damaged hips. Acetabular fractures managed either conservatively or operatively by fixation tend to present later with secondary joint changes that require THR. In this study we evaluated the functional outcome and quality of life achieved by such patients. METHODS: Our study was carried out as a retrospective trial by recruiting patients who underwent THR from June 2006 to May 2012. A total of 32 patients were included with a mean age of 46.08 years ranging from (25-65) years. We evaluated the quality of life in the patients using scoring techniques of Short Musculoskeletal Functional Assessment (SMFA) and the 12-Item Short Form Health Survey (SF-12). Functional outcome was assessed using Harris Hip Score (HHS). RESULTS: The mean HHS of the patients was 84.3 with a range from 56 to 100. The SMFA averaged 13.3. The SF-12 score averaged 49.1. The correlation of the HHS with SF-12 was positive (p =0.001) while with SMFA there was a negative correlation (p =0.001). CONCLUSION: From this study it is inferred that the functional outcome of THR and quality of life in patients who had acetabular fractures and were initially managed by open reduction and internal fixation is good.

BACKGROUND: Ankle and foot tuberculosis is relatively uncommon. Magnetic resonance imaging (MRI) is highly sensitive in detecting the changes but there is limited experience with MRI evaluation and differentiation from other mono-articular arthritis, particularly pyogenic arthritis, is a challenge. PURPOSE: To report MRI findings in ankle and foot tuberculosis. MATERIAL AND METHODS: MRI was performed in 17 selected patients with ankle and foot tuberculosis. T1-weighted, proton density (PD) weighted, T2-weighted, and postcontrast sequences were performed in multiple imaging planes. Recorded findings included: number of bones involved; specific bones involved; extent of involvement; erosions; joint effusion, synovial thickening, tenosynovitis; joint effusion; adjacent soft-tissue changes; and involvement of sinus tarsi. Clinical data of all patients were also reviewed. Radiographic correlation at the time of MRI was available in selected patients. RESULTS: The most common abnormality was synovial thickening. Signal abnormality was noted most frequently in the talus (n = 14). Erosions and intra-osseous abscesses were noted in 10 (58%) and eight (47%) patients, respectively. Tenosynovitis was present in eight (47%) patients. Soft tissue changes were noted in all patients, including abscesses in 13 patients (76%). CONCLUSION: A multiplicity of findings (both osseous and extra-osseous) on MRI favors the diagnosis of tuberculosis. Three findings (intra-osseous abscess, soft tissue abscess, tenosynovitis), when present together, have a high sensitivity and specificity.

BACKGROUND: A few animal studies have shown that IL-6 can serve as an early marker of fat embolism syndrome. The degree to which this is true in human trauma victims is unknown. QUESTIONS/PURPOSES: In this clinical study, we sought to determine (1) whether elevated serum IL-6 levels at 6, 12, and 24 hours in patients with skeletal trauma were associated with the development of fat embolism syndrome (FES) within 72 hours after injury, and (2) at what time after trauma peak IL-6 levels are observed. METHODS: Forty-eight patients between 16 and 40 years old who presented to our tertiary trauma center within 6 hours of injury with long bone and/or pelvic fractures were included in this study. Serum IL-6 levels were measured at 6, 12, and 24 hours after injury. The patients were observed clinically and monitored for 72 hours for development of FES symptoms. Gurd's criteria were used to diagnose FES. RESULTS: Elevated serum IL-6 levels 12 hours after trauma correlated with an increased likelihood of having FES develop; no significant relationship was observed between IL-6 levels at 6 or 24 hours and the development of FES. Patients with FES had a mean IL-6 level of 131 pg/mL, whereas those without FES had a mean IL-6 level of 72 pg/mL. Peak IL-6 levels were observed at 12 hours. CONCLUSIONS: An elevated serum IL-6 level may be useful as an early marker of FES in patients with isolated skeletal trauma. LEVEL OF EVIDENCE: Level II, diagnostic study.

Introduction: Orthopedic surgeons, owing to their specialized role, have a set of medical and moral responsibilities that span beyond the confines of the operating room. The primary objective of this exploration is to emphasize the pivotal ethical and professional standards that these surgeons should uphold. Methodology: We derived key ethical and professional aspects by reviewing standard medical practices, professional guidelines, and through consultations with senior orthopedic professionals. These aspects covered both the conduct inside the surgery room and the interpersonal relations outside. Results: Several core areas of conduct were identified.Patient-Centered Care: Prioritizing the holistic well-being of the patient.Communication: Ensuring that all communications are both transparent and respectful.Informed Consent: Properly securing consent after ensuring the patient is adequately informed.Confidentiality: Taking measures to safeguard patient information.Professional Behavior: Upholding the highest standards of professional conduct.Continuous Learning: Remaining committed to updating skills and enhancing competence.Interpersonal Relations: Building healthy and constructive relationships with industry representatives, professional peers, and hospital staff.Personal Life Balance: Recognizing the importance of a balanced personal and professional life for holistic well-being. Conclusion: For Orthopedic surgeons, strict adherence to the outlined ethical and professional principles is essential. Such commitment not only ensures the trust and safety of patients but also serves to maintain and elevate the prestigious standing of the orthopedic community in the broader medical landscape.
RESUMEN

This narrative review aimed to investigate the implementation and impact of an ethics-centric curriculum tailored for orthopedic postgraduate students. Methods: The proposed curriculum incorporates methodologies such as case-based learning, interactive discussions, and dedicated mentoring sessions, focusing on the unique ethical challenges encountered in orthopedics. Results: Introducing the curriculum provided postgraduate students with a robust foundation in ethical principles, enhancing effective communication, and fostering better doctor-patient relationships. Consequently, the students displayed an increased aptitude in navigating intricate ethical dilemmas in their clinical practice. Conclusion: There is a crucial need for continuous ethics education in orthopedics. Creating a supportive learning environment is essential to cultivate professionalism and promote patient-centered care. This study underscores the transformative potential of ethics training in molding orthopedic professionals who are both competent and deeply committed to maintaining the highest ethical standards.
RESUMEN
Background: Reduced bone density and increased fragility are hallmarks of osteoporosis, making the disease a major public health concern. The disease necessitates early diagnosis and appropriate therapy depend on an accurate evaluation of bone health. Essential tools for assessing osteoporosis include dual-energy X-ray absorptiometry (DEXA) and other imaging modalities. Methods: This chapter focuses on dual-energy X-ray absorptiometry (DEXA) and other imaging methods as essential tools for assessment of osteoporosis. The chapter also explores complementary imaging modalities that help overcome limitation of DEXA by providing insights into the microarchitecture and bone quality. Results: T-scores, used to categorise bone health, are determined by DEXA by comparing bone mineral density to age-matched standards. Bone mineral density (BMD) is the most common indicator of bone health; nevertheless, DEXA may misclassify bone health owing to reasons other than BMD. These constraints may be overcome with the use of complementary imaging methods, which provide information on the microarchitecture and quality of bone. The evaluation of bone structure is aided by high-resolution peripheral quantitative computed tomography (HR-pQCT), which produces precise 3D images of the trabecular and cortical bone compartments. Independent of traditional methods of gauging fracture risk, quantitative ultrasonography (QUS) uses an analysis of the characteristics of sound waves to determine bone health. Diagnostic precision is improved by magnetic resonance imaging (MRI) due to its ability to view bone marrow and trabecular structure without the use of ionising radiation. Discussion: New methods, such as the trabecular bone score (TBS), examine bone texture and provide more data on the likelihood of fracture than conventional DEXA. By modelling bone strength using imaging data, finite element analysis (FEA) provides a biomechanical viewpoint on breakage probability. These combined methods boost diagnostic accuracy and pave the way for individualised treatment plans. Imaging helps with therapy monitoring as well as diagnosis. By monitoring bone density and structure over time, therapy effectiveness or course corrections may be quickly identified. The availability of sophisticated imaging techniques and the standardisation of procedures provide obstacles not withstanding their advantages. Ongoing work is being done to solve these issues and standardise and disseminate these methods in a variety of contexts. Conclusion: The evaluation of osteoporosis is significantly aided by DEXA and other imaging methods. While DEXA is still the gold standard for diagnosing osteoporosis, other imaging techniques may shed light on bone health in greater detail. These methods improve fracture risk prediction and treatment assessment by providing information on bone architecture, quality, and strength. Integration of several imaging modalities shows potential for bettering osteoporosis therapy and patient outcomes as the field develops.
RESUMEN
Purpose: Although numerous systematic reviews and meta-analyses have established the efficacy of tranexamic acid (TXA) in hip fracture surgeries, the included studies in those reviews have included all types of surgical interventions ranging from fixation to arthroplasty. Hip hemiarthroplasty is usually indicated in the elderly patients with femoral neck fracture and these patients have associated severe comorbidities and cognitive impairment. These subsets of patients with femoral neck fracture needs appropriate perioperative care and judicious use of antifibrinolytics. There is no meta-analysis evaluating the safety and efficacy of intravenous TXA in these patients. Methods: Searches of PubMed, Embase and Cochrane Central Register of Controlled Trials databases revealed 102 studies on TXA in hip fracture surgeries. After screening, eight studies were found to be suitable for review. The primary objective of this meta-analysis was to compare blood transfusion rate between TXA vs. control in hip hemiarthroplasty. The secondary objectives were total blood loss, postoperative haemoglobin, surgical duration, length of hospital stay and side effects (VTE, readmission and 30 days mortality). Results: There were one RCT, one prospective cohort study and six retrospective studies. All studies recruited the elderly patients. Intravenous (IV) TXA administration resulted in significant reduction in requirement of blood transfusion (12.7% vs. 31.9%; OR 0.28; 95% CI 0.17-0.46; p < 00,001; I 2 = 73%). The TXA group had significantly decreased total blood loss (MD - 100.31; 95% CI - 153.79, - 46.83; p < 0.0002). The postoperative Hb in the TXA group was significantly higher than the control group (MD 0.53; 95% CI 0.35, 0.71; p < 0.00001). There was no significant difference in the incidences of VTE (0.97% vs. 0.73%, OR 1.27; p = 0.81; I 2 = 64%) and readmission rate (9.2% vs. 9.64%; OR 0.79; p = 0.54), but 30-d mortality rate was significantly lower in the TXA group (3.41% vs. 6.04%; OR 0.66; p = 0.03). Conclusions: Intravenous TXA is efficacious in the reduction of blood loss and transfusion need in hip hemiarthroplasty surgery for hip fracture, without increased risk of VTE. The blood conservation protocol led to decreased 30 days mortality in these fragile elderly patients. Level of evidence: III.
RESUMEN
OBJECTIVES: Nonspecific clinical presentations often lead to misdiagnosis of focal cysticercal myositis. This report emphasizes the role of ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of solitary intramuscular cysticercosis. MATERIALS AND METHODS: Six patients with persistent post-traumatic isolated muscular swelling were treated with analgesic and antibiotics, but the swelling did not subside. Radiographs showed soft tissue swelling with no bony abnormalities. Laboratory markers were inconclusive. Ultrasonographic and magnetic resonance images (MRI) showed typical features of intramuscular cysticercosis. Clinical, radiological, and fundoscopic evaluation of brain and eyes could not isolate any cysticercosis focus in these organs. Patients were treated with 3 weeks albendazole therapy. RESULTS: The identifying sonographic features of intramuscular cysticercosis, as evident from this case series, included an intramuscular elliptical or oval anechoic lesion with echogenic intralesional focus likely to be scolex. Magnetic resonance images showed orientation of the cyst along the direction of muscle fibers with T2W hyperintense signal and post-contrast perilesional enhancement. All patients responded to medical treatment. CONCLUSION: Cysticercosis may manifest as isolated muscular swelling without neurological or ocular involvement. Clinicians should be aware of this clinical condition to avoid misdiagnosis. Ultrasonography and magnetic resonance imaging are good diagnostic aids to establish soft tissue cysticercosis.

Fifty-one osteonecrotic hips in 40 patients were randomly divided into 2 treatment groups. Patients in group A (25 hips) were treated with core decompression, and those in group B (26 hips) received autologous bone marrow mononuclear cell instillation into the core tract after core decompression. Outcome between the 2 groups were compared clinically (Harris Hip score), radiographically (x-ray and magnetic resonance imaging), and by Kaplan-Meier hip survival analysis after 12 and 24 months of surgical intervention. The clinical score and mean hip survival were significantly better in group B than in group A (P < .05). Patients with adverse prognostic features at initial presentation, that is, poor Harris Hip score, x-ray changes, edema, and/or effusion on magnetic resonance imaging had significantly better clinical outcome and hip survival in group B than in group A.

PURPOSE: Conventional anterior column lag screw fixation in acetabular fracture is a difficult technique that has potential risks of vascular injury, hip joint penetration and excessive radiation exposure. We propose a safe technique of anterior column lag screw fixation (in-out-in technique) and present the outcome. MATERIALS AND METHODS: Twenty-seven acetabular fractures were operated through an iliofemoral approach, where the 'in-out-in technique' of lag screw fixation was a part of the surgical procedure. The technique involved insertion of a malleolar screw (4.5 mm) or 6.5 mm partially threaded cancellous screw from the outer side of the iliac wing, 0.5-1 cm posterior and inferior to the anteroinferior iliac spine. The screw comes out of the bone surface to re-enter into the anterior part of iliopectineal eminence, and finally gains purchase in the lateral part of superior pubic ramus. The screw fixation procedure was under direct visualization without resorting to an image intensifier. The average follow-up of the patients was at 18.6 months (range 12-36 months). RESULTS: No loss of reduction, joint penetration or visceral and neurovascular injury were documented. The average duration of surgery was 70 min and blood loss was 290 ml. All fractures were united after an average period of 2.8 months. Excellent to good functional outcome was observed in 24 patients (88 %), on evaluation with Merle D'Aubigne and Postel score at the latest follow-up. CONCLUSION: We conclude that the 'in-out-in technique' is a safe and effective method of anterior column lag screw fixation in acetabular fractures. It provides rigid stability and minimizes surgical duration, radiation exposure and intra-operative complications.

PURPOSE: Multiplex Polymerase Chain Reaction (MPCR) is a technique in which two or more gene targets are amplified in a single reaction. This has increased sensitivity of diagnosis as a single gene target may be absent in some Mycobacterium tuberculosis strains. METHODS: MPCR using two target genes specific for Mycobacterium tuberculosis, that is, IS6110 and MPB 64, ZN staining and Mycobacterial culture were performed on synovial fluid/pus samples of 80 (three confirmed, 77 suspected) patients of osteoarticular tuberculosis and 25 non tuberculosis patients. RESULTS: MPCR had a sensitivity of 100% in confirmed cases and 81.8% in clinically suspected cases. AFB was positive in one patient and Mycobacterial culture was positive in three patients. MPCR also had 100% specificity; MPB64 was positive in five patients in which IS6110 was negative whereas IS6110 was positive in two patients in which MPB64 was negative. CONCLUSIONS: MPCR is a sensitive and specific method for diagnosis of paucibacilliary conditions such as osteoarticular tuberculosis.

PURPOSE: Revision internal fixation for femoral-neck nonunion is a challenging procedure. Treatment options are osteotomy, osteosynthesis using various implants and grafting techniques (muscle pedicle, vascularised or nonvascularised fibular graft) or arthroplasty. The objective of this article is to report the outcome of revision internal fixation using an angle blade plate and autogenous fibular graft in symptomatic aseptic femoral-neck nonunion. METHODS: Twenty-two patients who had been treated previously with cannulated screws or dynamic hip screw for femoral-neck fracture and progressed to nonunion were treated with revision internal fixation using an angle blade plate and autogenous nonvascularised fibular graft. Mean patient age was 38 (range 21-52) years, with average duration between injury and revision surgery 11.2m (range 8-16 months). RESULTS: Other than one nonunion, we achieved union in all patients (21 patients, 91%) after an average period of 4.4 months. The functional outcome after 3.2 years as per scoring system given by Nagi et al.. showed excellent results in four, good in ten, fair in six and poor in two patients. Patients with poor results included one with nonunion and other with avascular necrosis with collapse of the femoral head. Average limb shortening was 1.5 cm, and mean femoral-neck-shaft angle was 116°. There was no instance of fibular graft fracture, slippage or implant cut-through. CONCLUSION: Angle blade plate provides rigid stability and offloads any shearing force over the fibular graft when used for revision internal fixation in aseptic femoral-neck nonunion. Thus, the fibular graft only serves the purpose of osteogenesis and stimulates the surrounding host cells to promote healing at the nonunion site. We recommend the angle blade plate and autogenous fibular graft as a viable option for hip-joint salvage in revision internal fixation of aseptic femoral-neck nonunion.

INTRODUCTION: Although lateral locking plate has shown promising results in distal femur fracture, there are high rates of varus collapse and implant failure in comminuted metaphyseal and articular fractures. This systematic review evaluates the functional outcomes and complications of dual plating in the distal femur fracture. MATERIALS AND METHODS: Manual and electronic search of databases (PubMed, Medline Embase and Cochrane Central Register of Controlled Trials) was performed to retrieve studies on dual plate fixation in the distal femur fracture. Of the retrieved 925 articles, 12 were included after screening. RESULTS: There were one randomized-controlled, four prospective and seven retrospective studies. A total of 287 patients with 292 knees were evaluated (dual plating 213, single plating 76, lost to follow-up 3). The nonunion and delayed union rates following dual plate fixations were up to 12.5% and 33.3%, respectively. The mean healing time ranged from 11 weeks to 18 months. Good to excellent outcome was observed in 55-75% patients. There was no difference between the single plate and dual plate fixation with regards to the functional outcomes (VAS score, Neer Score and Kolmert's standard) and complications. Pooled analysis of the studies revealed a longer surgical duration (MD - 16.84, 95% CI - 25.34, - 8.35, p = 0.0001) and faster healing (MD 5.43, 95% CI 2.60, 8.26, p = 0.0002) in the double plate fixation group, but there was no difference in nonunion rate (9.2% vs. 0%, OR 4.95, p = 0.13) and blood loss (MD - 9.86, 95% CI - 44.97, 25.26, p = 0.58). CONCLUSION: Dual plating leads to a satisfactory union in the comminuted metaphyseal and articular fractures of the distal femur. There is no difference between the single plate and dual plate with regards to nonunion rate, blood loss, functional outcomes and complications. However, dual fixation leads to faster fracture healing at the cost of a longer surgical duration.
