introduction anterior talofibular ligament (atfl) rupture is the most commonly injured anatomic structure in lateral ankle sprain. in some cases, atfl avulsion fracture from the lateral malleolus may occur instead of purely ligamentous injuries. the atfl avulsion fracture is detected as a small ossicle at the tip of lateral malleolus on direct radiographs, which is called os subfibulare in chro...

The coracoclavicular ligaments vary widely in morphology and anatomic descriptions. Few authors have adequately described the coracoclavicular ligaments' anatomy, and a number of discrepancies exist in the anatomy literature. This study examines the complex anatomy of the coracoclavicular ligaments and their relationships to clinically important bony landmarks. The geometric dimensions of 24 co...

Objective- Using the arthroscopic surgery technique for experimental transection of cranial cruciateligament and arthroscopic findings of stifle joint following ligament transection .Design- Experimental study.Animals- Five healthy mixed breed dogs. Procedures- Five dogs (mean weight 27±3 kg, mean age 3 years) selected to study the stifle joint changesafter experimental cranial cruciate ligamen...

The lateral aspect of the knee is stabilized by a complex arrangement of ligaments, tendons, and muscles. These structures can be demonstrated with routine spin-echo magnetic resonance (MR) imaging sequences performed in the sagittal, coronal, and axial planes. Anterolateral stabilization is provided by the capsule and iliotibial tract. Posterolateral stabilization is provided by the arcuate li...

OBJECTIVES To determine if screw displacement axis patterns describing elbow joint motion: (1) change after ligament transection in vitro; (2) can reflect subtle changes in stability as a function of forearm position; (3) can reflect dynamic stabilization of the ligament insufficient elbow provided by muscle activity.Design. An in vitro kinematic study of eighteen cadaveric specimens tested in ...

PURPOSE Severe or recurrent lower eyelid ectropion can be challenging to correct. Studies on the role of upper midface ptosis in lower eyelid malposition have been published. The authors describe their technique of supporting the lateral cheek by lifting and reestablishing support for the orbitomalar ligament through a 10-mm canthotomy incision as an adjunct to a lateral tarsal strip procedure....

BACKGROUND The orthopaedic literature contains relatively little quantitative information regarding the anatomy of the posterior aspect of the knee. The purpose of the present study was to provide a detailed description of, and to propose a standard nomenclature for, the anatomy of the posterior aspect of the knee. METHODS Detailed dissection of twenty nonpaired, fresh-frozen knees was perfor...

OBJECTIVES The aim of this study was to examine the relationship between cartilage, ligament, and meniscus degeneration and radiographic alignment in severe varus knee osteoarthritis in order to understand the development of varus knee osteoarthritis. DESIGN Fifty-three patients (71 knees) with primary varus knee osteoarthritis and who underwent total knee arthroplasty were selected for this ...

A gold standard for the correct rotation of the tibial component has not been established in total knee arthroplasty (TKA). The target parameter of correct rotation is the facilitation of femorotibial rotation over the entire range of motion with no implant overhang. Although the origin of the lateral collateral ligament is a recognized landmark for determining the rotation of the femoral compo...

Medical collateral ligament injuries are among the most common knee injuries for the athletic population. Immobilization once was the accepted course of treatment for MCL injuries but research has demonstrated the ineffectiveness of this approach. The knee is second only to the ankle in frequency of injuries in competitive sports and often more severe. Ruptures to the anterior cruciate ligament...
