During physiological motion, cervical spine ligaments limit the range of motion of the neck. However, the integrity of these ligaments can be compromised under excessive loading, specifically during vehicle crash scenarios, which is the leading cause of upper cervical spine injury [1]. Techniques to predict injury, such as the use of finite element models, require accurate mechanical properties...

The isolated bilateral agenesis of both cruciate ligaments is a rare congenital disorder. A 17-year-old male came to our attention due to an alteration in gait pattern, pain, and tendency to walk on the forefoot with his knee flexed. The patient did not recall previous injuries. Upon physical examination anterior and posterior chronic instability were observed. Radiographic examination of both ...

The purpose of this study was to review the clinical results of carpal ligaments injuries with scaphoid nonunion. We hypothesized that scaphoid nonunion with carpal ligament injury is associated with clinical result. We retrospectively reviewed 60 cases of -Herbert screw fixation with bone graft for scaphoid nonunions. Scapholunate (SL) and lunotriquetral (LT) ligaments lesions were confirmed b...

A new nonlinear constitutive model for the three-dimensional stress relaxation of articular ligaments is proposed. The model accounts for finite strains, anisotropy, and strain-dependent stress relaxation behavior exhibited by these ligaments. The model parameters are identified using published uniaxial stress-stretch and stress relaxation data on human medial collateral ligaments (MCLs) subjec...

Tendons and ligaments are dense fibrous bands of connective tissue that integrate musculoskeletal components in vertebrates. Tendons connect skeletal muscles to the bone and function as mechanical force transmitters, whereas ligaments bind adjacent bones together to stabilize joints and restrict unwanted joint movement. Fibroblasts residing in tendons and ligaments are called tenocytes and liga...

The main function of a ligament is to connect one bone to another bone across a joint, keeping them aligned to prevent abnormal motions and dislocations. The typical magnitude of force a ligament may experience during day-to-day activities varies. For example the anterior cruciate ligament of the knee can be exposed to daily tensile forces ranging between 67N for ascending stairs to 630N for jo...

background: sdft, ddft and suspensory ligament are the most important tendons and ligament of the palmar aspect of the metacarpus that contribute to stability mechanism. objectives: the purpose of this study was to describe the tendons and ligaments of the palmar surface of metacarpus in anatoly donkey and compare them with those in horse. methods: 14 healthy anatoly donkeys without lameness we...

Injuries to ligaments are common, painful and debilitating, causing joint instability and impaired protective proprioception sensation around the joint. Healing of torn ligaments usually fails to take place, and surgical replacement or reconstruction is required. Previously, we showed that in vivo application of the recombinant human amelogenin protein (rHAM(+)) resulted in enhanced healing of ...

INTRODUCTION A girl presented with achondroplasia manifested as mild knee pain associated with stiffness of her back. A skeletal survey showed enchondroma-like metaphyseal dysplasia and ossification of the spinal ligaments. Magnetic resonance imaging of the spine further clarified the pathological composites. CASE PRESENTATION A 7-year-old girl presented with the classical phenotypic features...

Background: The symptoms of rotator cuff tear vary and may even be absent. Thus, the symptoms cannot be explained solely by the presence of rotator cuff tear, and other factors are thought to be involved. Because the rotator cuff comes in contact with the coracoacromial ligament, the elasticity of the ligament may be a factor of the symptoms. The purpose of this study was to clarify the elastic...
