LESION BANKART HOMBRO PDF

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.

Lesión de Bankart

Bankart lesions do heal, and therefore early surgical intervention if any is not required. Further long-term clinical studies are necessary. In order to avoid this confusion, we proposed a new terminology: Locher et al 39 retrospectively analysed patients who underwent arthroscopic Bankart repair.

Case 2 Case 2. The only exception to this rule is the reverse Bankart, which is the result of a posterior dislocation and injury to the inferoposterior labrum. Bony defects created anteriorly. It is a very fundamental question. We apply this width 0. Sometimes the displacement is difficult to appreciate, especially when the transscapular-Y view is slightly rotated.

Continue with the images in ABER-position. Dislocations, sprains and strains Orthopedic problems Lesion. Bankagt the other hand, a HSL, which is out of the glenoid track off-track lesionhas a risk of engagement and dislocation. Osseus Bankart Bankart lesions with an osseus fragment are common findings in patients with an anterior dislocation and are frequently seen on the x-rays or CT-scan. There is also a Hill-Sachs defect red arrow. It should not be confused with Perthes disease of the hip.

This creates a negative intra-articular bankaet, which sucks the humeral head into the glenoid socket and prevents a downward translation of the humeral head. October Learn how and when to remove this template message.

Case 3 Case 3. The Latarjet procedure can convert an off-track lesion to an on-track lesion.

The physiologic groove in the humerus or cysts and erosions at the attachment site of the infraspinatus tendon can simulate a Hill-Sachs, but usually this is not a diagnostic problem figure. Reproduced with permission from Itoi E, Yamamoto N.

Med J Islam Repub Iran ; At the end-range of movement, a part of the shoulder capsule is tight, which prevents a translation of the humeral head on the glenoid socket. In the ABER position however there is tension on the antero-inferior labrum by the stretched anterior band of the inferior glenohumeral ligament and you have more chance to detect the tear.

Although the labrum may be normally positioned, functionally bankarrt no longer provides any stability to the humeral head, mainly as hombeo result of impairment of the normal stabilizing influence of the inferior glenohumeral ligament. The effect of a glenoid defect on anteroinferior stability of the shoulder after Bankart repair: The images show a partial tear of the anteroinferior labrum with adjacent cartilage damage at the o ‘clock position arrows.

You can help by adding to it. Posterior dislocations are associated with epileptic seizures, high energy trauma, electrocution and electroconvulsive therapy. Notice extention of the SLAP-tear further to posterior red arrow.

On the images a posterior dislocation is seen with a fracture. This page was last edited on 27 Octoberat This circle is considered to be close to the original shape of the glenoid.

In that case, a best-fit circle method can be used instead. Bony Bankart lesion Bankart lesions Soft Bankart lesion. Posterior homvro Posterior dislocations are uncommon and easily missed, because there is less displacement compared to the anterior dislocation.

La Chirurgia degli organi di movimento ; This results in instability and recurrent dislocations.

Intraarticular pressure of the shoulder. One method is dynamic examination. Posterior dislocations are uncommon and easily missed, because there is less displacement compared to the anterior dislocation. Sometimes this makes it easier to understand the anatomy.

Sometimes an axillary view can be of help, but when in doubt go to CT. SLAP tears typically extend from the 10 to the 2 o’clock position, but can extend more posteriorly or anteriorly and even extend into the biceps tendon.

Determination of prevalence of glenoid bony lesions after recurrent anterior shoulder dislocation using the 3-D CT scan. 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. For the purpose of assessing the risk of HSL relative to the glenoid, the glenoid track concept was introduced.
