The medial and lateral menisci play important roles in knee biomechanics, kinematics, and stability. Unfortunately, these structures are prone to damage and, because of a tenuous blood supply, have great difficulty healing. Many interventions have…

Scratches on bones have routinely been attributed to tooth marks (a predominantly untested speculation), ignoring the effects of claws, perhaps because of the general assumption that claws are too soft to damage bone. However, some pathologies…

Locomotion is precarious in an arboreal habitat, where supports can vary in both diameter and level of compliance. Several previous studies have evaluated the influence of substrate diameter on the locomotor performance of arboreal quadrupeds. The…

Minke whales (Balaenoptera acutorostrata) are the smallest member of balaenopterid whales and little is known of their kinematics during feeding maneuvers. These whales have narrow and elongated flippers that are small relative to body size compared…

BACKGROUND: The parameters of self-tapping screw (STS) performance in normal and osteoporotic bone have been defined in representative environments, but the question remains as to the clinical application of such findings. The goal of this study was…

STUDY DESIGN: A human growth hormone transgene was bred into mice of the Cola2oim (oim) lineage. Caudal (tail) vertebrae from male and female mice at early skeletal maturity and at midlife were evaluated for physical and biomechanical properties.…

Soft tissue allografts have many uses in orthopaedic surgery, including knee ligament reconstruction, hand tendon surgery, shoulder instability, and rotator cuff reconstruction. The predictable biologic incorporation of soft tissue allografts without…

OBJECTIVES: This study was performed to assess osseous contributions to osteoarthritis, obviating the analysis challenges presented by confounding factors in humans and rarity of osteoarthritis in free-ranging mammals. METHODS: Frequency of…

The leg tendons of certain avian species normally calcify. The gastrocnemius, or Achilles, tendon of the domestic turkey, Meleagris gallopavo, is one such example. Its structure and biomechanical properties have been studied to model the adaptive…

This study consisted of 26 male patients with distal biceps tendon ruptures, 2 of whom had bilateral injuries, making the total number of ruptures 28. The average age at injury was 45 years. The treatment groups were the following: 3 were treated…

Recently proposed ancestral locomotor and morphological 'stages' leading to the evolution of primates have emphasized small body size, and a transition from a clawed non-grasping stage, to a clawed, grasping stage with clawless opposable hallux, to a…

The distribution of peak vertical forces between the forelimbs and the hind limbs is one of the key traits distinguishing primate quadrupedal locomotion from that of other mammals. Whereas most mammals generate greater peak vertical forelimb forces,…

Patient expectations after primary total knee arthroplasty (TKA) continue to increase as the arthroplasty population becomes younger. Patients desire more than just pain relief, function, and the ability to return to higher level activities after…

As the smallest living primate, the mouse lemur is a suitable model for reconstructing the locomotor mechanisms by which primate ancestors might have responded to the challenges of an arboreal environment. In this study, we tested the effects of…

We examined masseter and temporalis recruitment and firing patterns during chewing in five male Belanger's treeshrews (Tupaia belangeri), using electromyography (EMG). During chewing, the working-side masseters tend to show almost three times more…

Recording reaction forces from primates during behaviors on vertical substrates, such as leaping, climbing, or biting trees, typically requires the design and construction of customized recording devices or mounting commercially available force…

The primate masticatory apparatus (MA) is a functionally integrated set of features, each of which performs important functions in biting, ingestive, and chewing behaviors. A comparison of morphological covariance structure among species for these MA…
