The aim of this study was to investigate whether a new periodontal ligament attachment will form on titanium implants when they are implanted with cultured periodontal ligament cells. Periodontal ligament cells obtained from the teeth of 3 dogs were cultured and attached to the surface of titanium implants. The implants with the cultured autologous periodontal ligament cells were placed in the ...

A study was carried out on the discomalleolar ligament by dissection of adult human cadavers. The ligament corresponds to the most internal portion of the superior lamina of the temporomandibular joint capsule. It extends from the posterointernal portion of the temporomandibular joint disc, penetrates the petrotympanic fissure and reaches the malleus of the middle ear. Because of its morphology...

The calcification of knee ligaments is a finding noted only in a handful of case reports. The finding of an anterior cruciate ligament calcification has been reported once in the literature. Comparable studies involving the posterior cruciate ligament, medial collateral ligament and an ossicle within the anterior cruciate ligament are likewise discussed in reports of symptomatic patients. We re...

BACKGROUND The individual biomechanical strength properties of the fibular collateral ligament, popliteofibular ligament, and popliteus tendon have not been well elucidated by previous studies. To define the necessary strength requirements for a posterolateral knee reconstruction, these properties for the main individual structures of the posterolateral knee need to be defined. HYPOTHESIS The...

The medial collateral ligament is one of the most frequently injured ligaments in the knee. Although the medial collateral ligament is known to provide a primary restraint to valgus and external rotations, details regarding its precise mechanical function are unknown. In this study, strain in the medial collateral ligament of eight knees from male cadavers was measured during valgus loading. A ...

Recently, medial patellofemoral ligament reconstruction has gained popularity as a treatment modality for recurrent patellar instability.2-6 Patients who have failed surgical interventions including lateral release, medial patellofemoral ligament reefing, and distal realignment may be good candidates for medial patellofemoral ligament reconstruction. The anatomy and biomechanics of the medial p...

INTRODUCTION Most ligaments of the human body have been well studied. However, the lumbocostal ligament has received little attention in the extant medical literature and, to our knowledge, has not undergone anatomical study. Therefore, the present study was performed to better characterize this structure's anatomy and relationships. METHODS In the prone position, 10 adult cadavers underwent ...

The discomalleolar ligament (Pinto's ligament) is not described in the anatomy textbooks but was demonstrated by Pinto and others. This is a ligamentous structure connecting the malleus in the tympanic cavity and the articular disc and capsule of the temporomandibular joint. This anatomical relationship between the middle ear and the temporomandibular joint is supposed to be one of the explanat...

A biomechanical in vitro study was performed on 16 fresh frozen cadaver forearms to investigate the role of the transverse carpal ligament (TCL) in carpal stability. The distance between the scaphoid and hamate was measured, as a reference for the length of the TCL. Distances were recorded in both loaded and unloaded conditions after gradual sectioning of the transverse carpal ligament, the pal...

The internal lateral ligament is the ligament most frequently damaged. Usually a few of the upper fibres are torn away from the periosteal attachment at the lower end of the femur. Occasionally, however, the deep fibres which are attached to the internal semilunar cartilage are partially torn without the cartilage being damaged. Occasionally, the external lateral ligament is injured. With more ...
