Prediction of joint moments from kinematics using machine learning in children with congenital talipes equino varus and typically developing peers.

Background: Understanding joint loading and the crucial role of joint moments is essential for developing treatment strategies in gait analysis, which often requires the precise estimation of joint moments through an inverse dynamic approach. This process necessitates the use of a force plate synchronized with a motion capture system. However, effectively capturing ground reaction force in typically developing (TD) children and those with congenital talipes equino varus (CTEV) presents challenges, while the availability and high cost of additional force plates pose additional challenges.

Gait variability and biomechanical distinctions in knee osteoarthritis: Insights from a 3D analysis in an adult elderly cohort.

Background: This study employs 3D gait analysis to investigate normal gait patterns in individuals afflicted with knee Osteoarthritis (OA). Focusing on the adult osteoarthritic population, the research aims to establish reference values for joint angles, temporospatial parameters, Gait Profile Score (GPS), and Movement Analysis Profile (MAP) collected concurrently along a standardized walking path. Furthermore, the study delves into potential variations linked to gender and OA severity, comparing gait parameters between male and female participants and among individuals with grade 3 and grade 4 OA.

Effect of total knee arthroplasty on contralateral knee: A prospective comparative gait analysis of non-operated legs in the Indian population.

Introduction: Biomechanics plays a crucial function in osteoarthritis. Changes in the biomechanical parameters of the contralateral knee following total knee arthroplasty (TKA) may result in pain in the contralateral knee. The objective of this study was to examine preoperative and postoperative gait measurements on the contralateral leg following a TKA for a variety of gait measures at a self-selected normal gait pace in a similar speed population.

Finite element analysis of a healthy knee joint at deep squatting for the study of tibiofemoral and patellofemoral contact.

Background: In non-western countries, deep squatting is a daily activity, and prolonged deep squatting is common among occupational squatters. Household tasks, taking a bath, socializing, using toilets, and performing religious acts are among the activities frequently carried out while squatting by the Asian population. High knee loading is responsible for a knee injury and osteoarthritis.

Estimation and Comparison of Knee Joint Contact Forces During Heel Contact and Heel Rise Deep Squatting.

Background: Increased knee flexion is required for deep squatting in the daily life of the non-western population as well as in many sports activities. The purpose of this study was to estimate as well as to compare knee joint contact forces during heel contact (HC) and heel rise (HR) deep squatting in 10 healthy young Indian participants.

Materials And Methods: Kinematic data were captured using a 12-camera Motion Analysis system.

Impact of COVID Pandemic on the Children with Cerebral Palsy.

Background: The COVID pandemic has been raging across the world for the past 18 months and has severely impacted healthcare and resources. Children with special needs have been adversely affected by the COVID pandemic, due to lack of formal schooling, access to rehabilitation and limited physical and social activity. The aim of this online survey was to understand the effect of the pandemic on the children with Cerebral Palsy (CP).

Longitudinal Observation of Changes in the Ankle Alignment and Tibiofibular Relationships in Hereditary Multiple Exostoses.

The longitudinal changes in the tibiofibular relationship as the ankle valgus deformity progresses in patients with hereditary multiple exostoses (HME) are not well-known. We investigated the longitudinal changes and associating factors in the tibiofibular relationship during the growing period. A total of 33 patients (63 legs) with HME underwent two or more standing full-length anteroposterior radiographs.

Titanium Elastic Nailing with Temporary External Fixator versus Bridge Plating in Comminuted Pediatric Femoral Shaft Fractures: A Comparative Study.

Background: High-velocity trauma, associated injuries, risk of iatrogenic devascularization of fragments and need for maintaining alignment upto union make comminuted fracture in pediatric femur a formidable fracture to treat. This comparative study was conducted to evaluate the outcomes of two modes of management in such cases: titanium elastic nailing supplemented with external fixator and submuscular bridge plating (BP).

Materials And Methods: Thirty eight children (aged 6-12 years) with comminuted fracture shaft femur who were randomized into two groups underwent systematic evaluation.

Persistent ulnar-sided wrist pain after treatment of triquetral dorsal chip fracture: six cases related to triangular fibrocartilage complex injury.

Introduction: Persistent ulnar-sided wrist pain after treatment of triquetral dorsal chip fracture even after union is a matter of concern. There could be various reasons for this persistent pain like arthritis, instability, fractures and non-union. We correlate our findings of physical examination and wrist arthroscopy as triangular fibrocartilage complex injury to be one of the causes of this persistent pain.

An approach to the supraclavicular and infraclavicular aspects of the brachial plexus.

The surgical approach to the brachial plexus is of great importance during surgery for brachial plexus injuries--obstetric or traumatic. A number of different approaches have been described over the years for these injuries, with each 1 having its own advantages and disadvantages. We describe a novel approach to the supra-clavicular and infra-clavicular aspects of the brachial plexus, which has been used by senior author successfully for the past 15 years.

Clinical outcome of shoulder muscle transfer for shoulder deformities in obstetric brachial plexus palsy: A study of 150 cases.

Background: Residual muscle weakness, cross-innervation (caused by misdirected regenerating axons), and muscular imbalance are the main causes of internal rotation contractures leading to limitation of shoulder joint movement, glenoid dysplasia, and deformity in obstetric brachial plexus palsy. Muscle transfers and release of antagonistic muscles improve range of motion as well as halt or reverse the deterioration in the bony architecture of the shoulder joint. The aim of our study was to evaluate the clinical outcome of shoulder muscle transfer for shoulder abnormalities in obstetric brachial plexus palsy.
