En ortopedia, la lesión de Bankart es una rotura de la parte anteroinferior del reborde glenoideo o labrum glenoideo de la escápula, a consecuencia de una luxación anterior de hombro. Perthes lesion is variant of Bankart lesion, presenting as an anterior glenohumeral injury that occurs when the scapular periosteum remains intact but is stripped. Sometimes, glenoid bone loss accompanies a bony fragment, which is called a bony Bankart lesion. This is observed in.

This was because in this position, the repaired anteroinferior capsule became tight and prevented the anterior translation of the humeral head, even with a large glenoid defect Fig. Acknowledgments The author thanks K-N.

A HSL which is small and narrow but is located medially needs special attention in selecting an optimum treatment option Fig.

It is named after Georg Clemens Perthes German surgeon, who first described the lesion in The image on the left shows lesionn absent anterosuperior labrum, which is called a Buford complex.

La Chirurgia degli organi di movimento ; This translation of the humeral head is called laxity. This means that MR-arthrography with the arm in the neutral position may fail to detect the labral tear. This resulted in both a Hill-Sachs impression fracture on the posterior aspect of the humeral head blue arrow and an impression fracture on the anterior aspect as a result of posterior dislocation red arrow.

Case 10 Case The magnitude and direction of the resultant force by the shoulder muscles depend on the activity and position of the arm. The glenoid socket is twice as deep in the superior-inferior direction as in the anteroposterior AP direction.

‘On-track’ and ‘off-track’ shoulder lesions

It is named after Georg C. There is a Bankart lesion with extension into the cartilage, i. They also have a typical location.

For the latter, there are also two methods to express the defect size: During arthroscopic surgery, the relative relationship between the HSL and the glenoid can be assessed.

Retrieved from ” https: The dislocation of the humeral head to antero-inferior causes damage to the antero-inferior rim of the glenoid in the 3 – bbankart o’clock position marked in red. SLAP tears typically extend from the 10 to the 2 o’clock position, but can extend more hombrk or anteriorly and even extend into the biceps tendon.

Quantifying glenoid bone loss arthroscopically in shoulder instability. For this reason, some insist that the term “Bankart lesion” be reserved for soft tissue injury. This was an incidental finding on a chest-film.

The shoulder joint is a ball-and-socket ldsion. Clinical outcome and glenoid morphology after arthroscopic repair of chronic osseous Bankart lesions: Arthroscopic repair of glenoid fractures using suture anchors.

Luxación de hombro, Inestabilidad del hombro, lesión del labrum hombro

In our daily practice, we use en face views of both glenoids and the posterior view of the involved humeral head on 3D CT. Case 2 Case 2.

There are two types of labral tears: Notice how this high signal continues posteriorly, which means that it is a SLAP-lesion. The lesion is best identified on MR arthrography. However, baniart the HSL is still off-track after the Latarjet procedure, either remplissage or bone graft to the HSL needs to be added to the Latarjet procedure.

Shoulder MR – Instability

Current Orthop Practice ; Sometimes this makes it easier to understand the anatomy. The Latarjet procedure can convert an off-track lesion to an on-track lesion. Surgery of the Musculoskeletal System. The effect of a glenoid defect on anteroinferior stability of the shoulder after Bankart repair: Location of the glenoid defect in shoulders with recurrent anterior bsnkart.

Perthes lesion

This stabilising mechanism is called a concavity-compression effect. Case 3 Case 3. Whatever the magnitude and direction, the perpendicular component of the resultant force against the glenoid socket multiplied by the stability ratio determines the resistance force.
