How is a Bennett lesion treated?
Although no consensus exists, surgical treatment may be indicated in patients who experience continued pain and disability after nonsurgical treatment. Bennett lesion resection is performed arthroscopically or via open surgery.
What is a Bennett lesion?
A Bennett lesion is a bony spur at the posterior glenoid that is often seen in baseball players and usually asymptomatic. However, it sometimes becomes painful, but the mechanism of throwing pain is still unknown.
Which radiographic view is most preferable for shoulder dislocation?
CT is mainly indicated after traumatic injury of the shoulder to rule out fractures not visible in radiographs or to assess the extent and severity of fractures already depicted in previous radiographs. CT is also useful to assess humeral and glenoid version. Excessive version can lead to instability (Figure 3).
Does MRI show shoulder instability?
MRI and arthrographic studies are very accurate in showing chondral and labral injuries (such as Bankart lesion, ALPSA, GLAD and HAGL, as well as their counterparts in posterior instability).
How do SLAP lesions occur?
A SLAP lesion is mainly caused by a fall on an outstretched arm where there is an important superior compression on the labrum which causes a tear of the labrum. A typical symptom is intermittent pain that also occurs in overhead movements.
What is a Bankart lesion in shoulder?
One of the most common labral injuries is known as a Bankart lesion. This condition occurs when the labrum pulls off the front of the socket. This occurs most often when the shoulder dislocates. If a Bankart tear doesn’t heal properly, it can cause future dislocations, instability, weakness and pain.
Does a MRI scan show nerve damage?
An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings.
Can a rotator cuff tear be missed on an MRI?
An MRI scan is often done to diagnose a SLAP tear and other potential injuries to the muscles, tendons, ligaments, and cartilage in the shoulder. Because of the many overlapping and interwoven structures in the shoulder, it is possible for an MRI scan to miss a smaller tear.
Where do you feel pain with a SLAP tear?
Common SLAP tear symptoms include: Shoulder pain that can be a persistent dull ache or a sharp pain deep in your shoulder. Shoulder pain in certain positions, like raising your arm or stretching your arm behind your head. Shoulder pain when you do certain things, like throwing a ball or reaching overhead.
Can a SLAP tear in shoulder heal on its own?
SLAP tears are often painful and can cause clicking in the shoulder. They often occur as a result of a jarring motion of the arm. Unfortunately, SLAP tears do not heal on their own and usually require surgery to allow them to heal properly.
When to use a non contrast MRI for shoulder injury?
Non-contrast magnetic resonance imaging for diagnosing shoulder injuries. Non-contrast MRI is reliable only for diagnosing full thickness rotator cuff tears and anterior labral tears. Direct or indirect contrast enhancement is recommended for more differentiation. Special scan orientation is necessary for SLAP tears.
How is the arthroscopic excision of the posterior Bennett lesion?
Since first described by Meister et al. 3 in 1999, arthroscopic excision of the posterior Bennett lesion has consisted of variations on capsulotomy, soft-tissue debridement for the purpose of visualization, removal of the posterior glenoid exostosis, and contouring of the glenoid rim.
Where is the Bennett lesion in the glenoid?
An axial view shows the Bennett lesion in the posteroinferior aspect of the glenoid (arrows).
What kind of ossification is Bennett’s exostosis?
Bennett lesions, also known as “thrower’s exostosis” of the shoulder, involve ossification of the posteroinferior glenoid and are not uncommon in overhead throwing athletes. The literature surrounding the optimal operative management of the symptomatic Bennett lesion is limited.
