Introduction: The tibia bone forms the main skeleton of the leg. It plays an important role in weight bearing and takes part in the formation of knee joint. The knowledge of different dimensions of upper end of tibia will help the orthopaedic surgeons for diagnosis, planning and treatment of disease related to knee. Inappropriate design of knee replacement could affect the outcome of surgery with reported complications. The objective of the study is to find out the morphometric measurements of upper end of tibia in Nepalese Population. Methods: After ethical approval (MEMG/IRC/211/GA) the study was done on 60 dry tibia bones of Nepalese citizens irrespective of sex and race in the Department of Anatomy, Manipal College of Medical Sciences, Pokhara. The morphometric measurements of medial condyle, lateral condyle, intercondylar area and circumference of upper end of tibia of both sides were measured manually by thread, scale and Vernier calliper. Data were reported as mean ± SD and analyzed with MS Excel 2007 software. Results: Average anteroposterior measurements were found to be 46.38 mm and 39.14 mm and average transverse measurements were 28.79 mm and 27.86 mm respectively for medial and lateral condyles of both sides. The anteroposterior and transverse measurements of intercondylar area of tibia were 47.75 mm and 7.11 mm on the right side and 49.81 mm and 7.25 mm respectively on the left side (p<0.05). Similarly mediolateral length and circumference of upper end of tibia of left limb were significantly greater than the right limb (p<0.05).  Conclusion: The knowledge of different dimensions of upper end of tibia may be important in anthropological practice. Morp hometric parameters of upper end of tibia will be important to orthopaedic surgeons for diagnosis, planning and treatment of disease related to knee in Nepalese population.

: Knee deformities can be reliably assessed by using morphometric parameters of upper end of tibia. Total knee arthroplasties are done to treat many types of arthritis and injuries involving knee joint. So, there is a need to have data of various morphometric parameters of upper end of tibia in order to have better surgical outcomes. The present study was attempted to provide values of different parameters in the population of Bihar.: The present study was a cross-sectional and prospective study conducted on 50 tibia of unknown gender and age in the Department of Anatomy, Indira Gandhi Institute of Medical Sciences, Patna. Fully ossified, dried, macerated and thoroughly cleaned tibia were taken to measure different parameters of upper end with the help of digital vernier calliper. The data thus obtained were tabulated and analysed statistically using Microsoft excel software.: It was found that the diameters of medial condyle were more than the lateral condyle. The antero-posterior diameter was more than the transverse diameter in case of both the condyles. But the difference between the right and the left side was not statistically significant.: The present study will help in providing a baseline data for designing of the prosthesis used in total knee replacement surgeries. It will also be helpful to anthropologists and forensic experts.

Background: The anterior reach distance and symmetry of the Y-Balance Test (YBT) has been associated with increased injury risk in collegiate athletes. Examining the influence of dorsiflexion range of motion (DROM) and single-limb balance (SLB) on YBT performance may identify underlying factors associated with injury risk. Objective: The purpose of this study is to determine if YBT anterior reach is related to DROM or SLB in collegiate varsity and club sport athletes. Methods: A convenience sample of 124 university varsity and club sport athletes (females: 99, age: 20.0 ± 1.6 years, height: 168.9 ± 12.5 kg, body mass: 68.8 ± 14.0 kg) completed the anterior direction of the YBT, weight-bearing DROM, and SLB components (firm and foam surface) of the Balance Error Scoring System on both limbs at one testing session. Relative symmetry was calculated by subtracting values of the left limb from the right limb. Results: For the left and right limb, normalized anterior reach distance was moderately correlated to DROM (R = .55, p < .001). Anterior reach distance and symmetry was weakly correlated to SLB and SLB symmetry (R = −.16 to −.03). Conclusion: There was a positive relationship between YBT anterior reach and weight-bearing DROM which was also observed in the between-limb symmetry. However, weak relationships were exhibited between YBT anterior reach and SLB. These findings may be useful for future injury prevention initiatives in athletic settings.

Background: Total knee arthroplasty is the most cost effective and rapidly evolving technique. The success of procedure relies on appropriate sizing of tibial component, for which elaborate information of various dimensions of upper surface of tibia is mandatory. Hence, this study is aiming to generate baseline data on antero-posterior and transverse measurements of medial and lateral condyles and intercondylar area of upper surface of tibia. Methods: The study was conducted in 42 dry human cadaveric tibia with unidentified age and sex, in the Department of Anatomy, College of Medical Sciences and Teaching Hospital, Chitwan. The antero-posterior and transverse measurements of medial and lateral condyles and intercondylar area of tibia were recorded in millimeter (mm) with digital Vernier calipers. The data was analysed using SPSS version 16.0. Results: The antero-posterior and transverse measurements of medial condyle of tibia were 43.00±5.95 mm and 25.21±8.08 mm respectively on the right side and 45.33±5.36 mm and 27.43±8.57 mm respectively on the left side and that of lateral condyle were 37.94±5.64 mm and 25.21±8.71 mm respectively on the right side and 41.03±3.65 mm and 27.06±8.83 mm respectively on the left side. The antero-posterior and transverse measurements of intercondylar area of tibia were 47.49±6.31 mm and 15.71±3.93 mm respectively on the right side and 49.24±6.91 mm and 15.02±3.88 mm respectively on the left side. The variation in the measurements between right and left tibia showed significant difference only for antero-posterior measurement of lateral condyle (p<0.05). Conclusions: The study generates baseline data regarding various anthropometric measurements of upper surface of tibia, which will assist the orthopedic surgeon to create a resected bony surface identical to the tibial component of an implant in unilateral and total knee arthroplasty.

Objective Early detection of degenerative changes in the cartilage matrix composition is essential for evaluating early interventions that slow down osteoarthritis (OA) initiation. T1rho and T2 relaxation times were found to be effective for detecting early changes in proteoglycan and collagen content. To use these magnetic resonance imaging (MRI) methods, it is important to document the topographical variation in cartilage thickness, T1rho and T2 relaxation times in a healthy population. As OA is partially mechanically driven, the relation between these MRI-based parameters and localized mechanical loading during walking was investigated. Design MR images were acquired in 14 healthy adults and cartilage thickness and T1rho and T2 relaxation times were determined. Experimental gait data was collected and processed using musculoskeletal modeling to identify weight-bearing zones and estimate the contact force impulse during gait. Variation of the cartilage properties (i.e., thickness, T1rho, and T2) over the femoral cartilage was analyzed and compared between the weight-bearing and non-weight-bearing zone of the medial and lateral condyle as well as the trochlea. Results Medial condyle cartilage thickness was correlated to the contact force impulse ( r = 0.78). Lower T1rho, indicating increased proteoglycan content, was found in the medial weight-bearing zone. T2 was higher in all weight-bearing zones compared with the non-weight-bearing zones, indicating lower relative collagen content. Conclusions The current results suggest that medial condyle cartilage is adapted as a long-term protective response to localized loading during a frequently performed task and that the weight-bearing zone of the medial condyle has superior weight bearing capacities compared with the non-weight-bearing zones.

Introduction: In order to achieve the right balance of the posterior cruciate ligament using the skeletal method is very difficult, almost impossible (Mahoney). Our hypothesis for the right balance of the PCL by using the skeletal method is based on several defined facts: - PCL is a union based of two anatomically independent, but functionally synergic parts, posteromedial and anterolateral part. - The length of the posteromedial part of the PCL is determined by the belonging of the medial compartment and is shortest in varus and longest in valgus deformation. - The length of the anterolateral part of the PCL, placed centrally is unchangeable (cca 38 mm) in every knee and is independent from the anatomical appearance (deformation). - The cylindrical shape of the distal posterior part of the femur (Ficat) depends of the molding function of the PCL (Kapandji) and is a result of the proportion of the both parts of the PCL that is consisted of: shorter posteromedial part, less bone stock on the medial and more bone stock on the lateral condyle (varus knee) and vice versa, longer posteromedial part, more bone stock on the medial condyle and less on the lateral (valgus knee). According to that, the neutral bone stock is achieved by equalization of the lengths of the two parts (common radius of the cylinder) of the PCL, that is basis for the interligamentary balance of the posterior cruciate ligament. Methods: The basic characteristics of the interligamentary balance of the PCL that we started in 2008 are the following: 1. Posterior condylar offset is equal to the even length of the both part of the PCL. 2. Decrease of the values of proximal tibial resection from 10 in varus to 4-6 in valgus. 3. Femoral valgus cut from 6 in excessive varus deformity to 4 in valgus. Results: The clinical evaluation of the cases divided in groups excessive varus, mean varus, valgus type 1, 2 (Krakow) showed right distribution in the groups of the postoperative ROM and intraoperative tenacity of the PCL (POLO test and palpation test), as a confirmation to the hypothesis. Conclusions: The ligamentary apparatus of the knee by the molding function depends on the skeletal morphology of the distal posterior femur to the degree that there aren’t two identical knees (Kapandji). According to that, every PCL has its own knee.

BACKGROUND Osteoarthritis of knee joint is one of the major health problems, due to the evolution of erect posture. Upper weight bearing end of tibia is most vulnerable to damage in such patients. Total knee arthroplasty and unicompartmental arthroplasty are the most frequently done procedures, which require the use of adequate knee prosthesis. So, the present study was focused at providing morphometric data of upper articular end of tibia for designing the tibial component of prosthesis. METHODS The present study has been conducted in SAMC & PGI, Indore in the Department of Anatomy. 80 dry tibia bones were studied, of which 33 were right sided and 47 were left sided. Maximum anteroposterior (AP) length and width of upper surface of medial and lateral condyles and intercondylar area were measured with digital vernier caliper. RESULTS The average anteroposterior diameter was found to be greater than the transverse diameter for both the condyles and the intercondylar area, irrespective of side. Furthermore, the anteroposterior diameter and the transverse diameter of medial condyle was more than that of lateral condyle on both the sides. In intercondylar area, the anteroposterior diameter was found to be more on right side while transverse diameter was more on left side. CONCLUSIONS The present study demonstrates the accurate complete comparative measurements of all the parameters of upper surface of medial and lateral condyles and intercondylar area. The morphometric data obtained will provide guidelines for designing tibial component of knee prosthesis in central Indian population. Apart from clinical significance, the study has anthropological and medicolegal importance as well. KEYWORDS Morphometry, Upper End of Tibia, Knee Joint

This research article focuses on the theme of violence and its representation by the characters of the novel “This Savage Song” by Victoria Schwab. How violence is transmitted through genes to next generations and to what extent socio- psycho factors are involved in it, has also been discussed. Similarly, in what manner violent events and deeds by the parents affect the psychology of children and how it inculcates aggressive behaviour in their minds has been studied. What role is played by the parents in grooming the personality of children and ultimately their decisions to choose the right or wrong way has been argued. In the light of the theory of Judith Harris, this research paper highlights all the phenomena involved: How the social hierarchy controls the behaviour. In addition, the aggressive approach of the people in their lives has been analyzed in the light of the study of second theorist Thomas W Blume. As the novel is a unique representation of supernatural characters, the monsters, which are the products of some cruel deeds, this research paper brings out different dimensions of human sufferings with respect to these supernatural beings. Moreover, the researcher also discusses that, in what manner the curse of violence creates an inevitable vicious cycle of cruel monsters that makes the life of the characters turbulent and miserable.

Abstract Background We present a case of an immense unprecedented tibial bone lengthening of 33.5 cm. The management of chronic osteomyelitis of the right tibia with subtotal tibial bone defect, talus defect and equinus ankle deformity. We demonstrate limb reconstruction by distraction osteogenesis and correction of ankle deformity with the Ilizarov technique. Limb salvage was preferred as an alternative to amputation to restore basic limb function. Case presentation A 16-year-old male patient fell and injured his right lower leg. He attempted to treat the symptoms with traditional home remedies. During 15 months of self-treating, he developed osteomyelitis of the right tibia and had lost function in his foot. Radiology revealed immense bone defect of the right tibia, including talus bone defect and equinus deformity of the calcaneus. The patient’s right tibia was non weight-bearing, had drainage sinus just below his knee and a large scar anteriorly along the entire length of the tibia. Conclusion Upon completion of treatment, the patient was able to avoid amputation of his leg with partially restored function for weight-bearing. He carried himself without assistance after 3 years of lost function in his right leg. Tibial bone distraction osteogenesis of 33.5 cm was done after 90% of the tibial length was defected. To the best of our best knowledge, this case is one of a kind to achieve distraction of tibial bone to such length.
