Prevalence of Avascular Necrosis Following Surgical Treatments in Unstable Slipped Capital Femoral Epiphysis (SCFE): A Systematic Review and Meta-Analysis.

The choice of treatment for unstable and severely displaced slipped capital femoral epiphysis (SCFE) is controversial. This meta-analysis was conducted to determine the prevalence of femoral head avascular necrosis (AVN) following various treatments for unstable SCFE. Various databases were searched to identify articles published until 4 February 2022.

A review of bioceramics scaffolds for bone defects in different types of animal models: HA and-TCP.

Increased life expectancy has led to an increase in the use of bone substitutes in numerous nations, with over two million bone-grafting surgeries performed worldwide each year. A bone defect can be caused by trauma, infections, and tissue resections which can self-heal due to the osteoconductive nature of the native extracellular matrix components. However, natural self-healing is time-consuming, and new bone regeneration is slow, especially for large bone defects.

Corrective Mechanism Aftermath Surgical Treatment of Spine Deformity due to Scoliosis: A Systematic Review of Finite Element Studies.

This paper presents a systematic study in reviewing the application of finite element method for the analysis of correction mechanism of spine deformity due to scoliosis. The study is aimed at systematically (1) reviewing the use of finite element analysis in spine deformity case, (2) reviewing the modelling of pedicle screw and rod system in scoliosis surgery, and (3) analysing and discussing gap between the studies. Using the restricted key phrases, the review gathered studies from 2001 to 2021 from various electronic databases (Scopus, ScienceDirect, PubMed, Medline, and WorldCAT).

Finite Element Prediction on Fracture Load of Femur with Osteogenesis Imperfecta under Various Loading Conditions.

Osteogenesis Imperfecta (OI) is an inherited disorder characterized by extreme bone fragility due to collagen defects. It is an incurable disease. Bone fractures can occur frequently without prior notice, especially among children.

Commemorating the 40-Year Journey of the School of Medical Sciences, Universiti Sains Malaysia.

The School of Medical Sciences of Universiti Sains Malaysia (USM) is the launching pad for this journal. From the school's humble beginning at the USM Main Campus in Pulau Pinang, Malaysia, it has grown in stature at its current location in the USM Health Campus, Kubang Kerian, Kelantan, Malaysia. Commemorating its 40th anniversary, this editorial aims to recollect, although not exhaustively, the wealth of returns for the USM, as well as for the nation, which the school has managed to deliver in that period.

The effect of leg length inequality on joint contact forces of lower limbs during walking.

Purpose: The aim of this study was to examine the joint contact forces (JCF) between each limb as the LLD magnitude increases during walking activity.

Methods: Eighteen male healthy subjects volunteered to participate in the experiment. Walking gait analysis was conducted with eight different levels of insole to simulate the LLD, starting from 0 cm until 4.

Ankle reconstruction and lengthening strategy in type II fibular hemimelia: a report of two cases.

Limb lengthening of fibular hemimelia is associated with progressive ankle valgus deformity. We reported a successful tibial lengthening in fibular hemimelia without recurrence of ankle valgus in 2 cases. The procedure involved 2 stages.

Leg Length Discrepancy: Dynamic Balance Response during Gait.

Balance in the human body's movement is generally associated with different synergistic pathologies. The trunk is supported by one's leg most of the time when walking. A person with poor balance may face limitation when performing their physical activities on a daily basis, and they may be more prone to having risk of fall.

Long-term effect on foot and ankle donor site following vascularized fibular graft resection in children.

This study was carried out to evaluate the long-term effect on the donor side of the foot and ankle following vascularized fibular graft resection in children. Eight patients underwent resection of the fibula for the purpose of a vascularized fibular graft by a surgical team who practiced leaving at least 6 cm residual distal fibula. The age of these children at the time of surgery was between 3 and 12 years.

Influence of Age, Weight, and Pirani Score on the Number of Castings in the Early Phase of Clubfoot Treatment using Ponseti Method.

Background: The objectives of this study were to investigate whether severity of clubfoot, age, and weight of the patients at initial manipulation and casting influence the total number of castings required.

Methods: This prospective study was conducted on 38 idiopathic clubfoot patients undergoing weekly manipulation and casting using the method recommended by Ponseti. The patients' age, weight, and foot Pirani score at the start of manipulation and casting were analysed against the total number of castings required to achieve correction to 60° abduction.

Breakage of an intramedullary rod after bone union in congenital pseudoarthrosis of the tibia: a report of two cases.

We report 2 patients with congenital pseudoarthrosis of the tibia who underwent intramedullary Rush rod transfixation through the ankle joint following refracture and nonunion of vascularised fibular grafting 6 and 8 months earlier. After 9 and 5 years, both Rush rods were broken at the level of the ankle joints, while the reconstructed area was solidly united. The growth of the distal tibia increased the distance of the tips of the broken rod and hence the ankle joint motion.

A modified surgical technique for neglected fracture of lateral humeral condyle in children.

Operative treatment for neglected fracture of lateral humeral condyle (LHC) is difficult because of contracted muscle, fibrous tissue formation, and indistinct bony edges. Its success depends on the ability to preserve blood supply during the surgery. We retrospectively reviewed eight cases of neglected fracture of LHC in children treated with open reduction with selected multiple 'V' lengthening of common extensor muscle and internal fixation.
