Mcl origin and insertion

Medial Collateral ligament Anatomy-. Thickening of the joint capsule.

The medial collateral ligament is composed of two portions superficial MCL and deep MCL.

Mcl origin and insertion. Medial Collateral ligament Anatomy-. MCL originates from the femurs medial epicondyle and inserts into the posterior medial surface of the proximal tibia. The medial collateral ligament is composed of two portions superficial MCL and deep MCL.

The MCL originates on the medial aspect of the distal femur and inserts on the medial aspect of the proximal tibia several centimeters below the joint line. Its deep fibers are intimately interlaced with the joint capsule at the level of the joint and the medial meniscus is attached directly to it. Originates from medial femoral epicondyle and inserts into periosteum of proximal tibia deep to pes anserinus the superficial portion of the MCL contributes 57 and 78 of medial stability at 5 degrees and 25 degrees of knee flexion respectively.

The superficial MCL is the primary stabilizer to valgus stress at all angles. Medial collateral ligament Injury of the knee MCL Tear are the most common ligament injuries of the knee and are frequently associated with ACL tears. They are cause by either a direct blow more severe tear or a non-contact injury less severe.

Treatment is usually bracing unless there is gross varus instability in which case repair or reconstruction is performed. Cial MCL femoral origin is located 32 mm proximal and 48 mmposteriortothemedial epicondyleThe ligament inserts distally on the tibia at 2 points approximately 122 mm and 612 mm distal to the joint line Fig 12 MCL injury severity is categorized as grade 1 grade 2 and grade 3 based on asymmetrical medial joint space. The femoral origin of the MCL is identified and marked.

The medial joint line is also marked with a needle. The distal tibial attachment sites of the deep medial collateral ligament dMCL and superficial medial collateral ligament sMCL are marked with a ruler which are 1 cm and 6 cm distal to the medial joint line respectively. The guide pin is inserted into the femoral attachment site of the MCL from media.

The MCL complex runs from the humerus to the ulna and is composed of three parts 1347. Inferior medial epicondyle to the sublime tubercle of the medial coronoid process. Medial epicondyle to the medial olecranon.

Thickening of the joint capsule. Transverse or oblique bundle Coopers ligament. Knee origins and insertions.

Prevent valgus motion of the knee or inward buckling of the knee. The medial collateral ligament MCL is com-posed of superficial and deep fibers to provide the knee with medial and rotatory stability. Its deep fibers may be torn with meniscal tears because of their direct attachment.

OriginPosterior aspect of the medial gastrocnemius femoral condyle Insertion. Dorsal part from C4-6 vertebraes transverse processes medial part from C6-7 vertebraes transverse processes o Insertion. - the dorsal scalenus has two muscular parts inserting on the cranial border of ribs.

The dorsally situated on the first four ribs the ventrally situated is longer and inserts on the first eight-nine ribs - the middle scalenus inserts on the cranial border of. The complex of the medial collateral ligaments of the ankle joint is collectively called deltoid ligamentIt attaches the medial malleolus to multiple tarsal bones. The ligament is composed of two layers.

The superficial layer has variable attachments and crosses two joints while the deep layer has talar attachments and crosses one joint. Anterior cruciate ligament ACL origin. Anterior cruciate ligament ACL insertion.

Posterior cruciate ligament PCL origin. Posterior lateral side of tibia. Posterior crucuiate ligament PCL insertion.

Medial collateral ligament origin. This ligament is in relation with the triceps brachii and flexor carpi ulnaris and the ulnar nerve and gives origin to part of the flexor digitorum superficialis. However the relationship between the footprint anatomy and the physes are not clearly defined.

The purpose of this study was to identify the origin and insertion of the ACL and MCL and define the footprint anatomy in relation to the physes in skeletally immature knees. The median distance from the MCL femoral origin on the epiphysis to the distal femoral physis was 120 cm interquartile range 100 to 120 cm and 085 cm interquartile range 063 to 100 cm for groups A and B respectively. The median distance from the MCL insertion on the tibial metaphysis to the tibial physis was 305 cm interquartile range 263 to 330 cm and 480 cm.
