What is the greater tuberosity?
The greater tuberosity is the “bump” of bone at the top of the humerus that serves as the attachment for two rotator cuff muscles. This attachment is why a fracture can also interfere with the functioning of the rotator cuff.
What attaches to greater tuberosity of humerus?
The greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles – supraspinatus and infraspinatus.
What tendon attaches to greater tuberosity?
Muscle Attachments
| Muscle | Attachment |
|---|---|
| Supraspinatus | Greater Tubercle |
| Infraspinatus | Greater Tubercle |
| Teres Minor | Greater Tubercle Upper Part of the Lateral Border |
| Subscapularis | Lesser Tubercle |
What is irregularity of the greater tuberosity?
Cortical irregularity of the greater tuberosity and shoulder joint effusion, which manifests as anechoic fluid in the axillary pouch, posterior recess, and sheath of the long head of the biceps tendon, are also considered secondary signs of rotator cuff tear (,Fig 20,).
Can a humerus bone heal without surgery?
Most proximal humerus fractures can be treated without surgery. The broken bone will take 3 to 4 months to heal. During this time, you will need to perform exercises to regain range of motion, strength, and return to normal activities.
How do you fix a greater tuberosity fracture?
In these cases, surgical treatment is recommended. Multiple surgical techniques include open and arthroscopic options tailored to fracture morphology, and strategies for repair include the use of suture anchors, transosseous sutures, tension bands, and plates/screws.
How long does it take for a fracture of the greater tuberosity to heal?
You have sustained a fracture of your greater tuberosity of your shoulder. The shoulder is a ball and socket joint you have fractured the outside of the ball part. This normally takes between 6-12 weeks to unite (heal).
How long does a greater tuberosity fracture take to heal?
Do you need to wear a brace at all times when you break your humerus?
In many cases, proximal and mid-shaft humerus fractures don’t require surgery because the broken ends usually stay close together. This makes it easier for your humerus to heal on its own. However, you’ll still need to wear a sling, brace, or splint to keep your arm from moving and stabilize your shoulder, if needed.
What does tuberosity mean in medical terms?
Tuberosity – A moderate prominence where muscles and connective tissues attach. Its function is similar to that of a trochanter. Examples include the tibial tuberosity, deltoid tuberosity, and ischial tuberosity. Tubercle – A small, rounded prominence where connective tissues attach.
Can you sleep lying down with a broken humerus?
Lay flat. Though it may be uncomfortable, try sleeping, as much as possible, in a seated/upright position. Lying flat may allow the bone to move and bend, even in a cast.
What is the purpose of a tuberosity on a bone?
In the skeleton of humans and other animals, a tubercle, tuberosity or apophysis is a protrusion or eminence that serves as an attachment for skeletal muscles. The muscles attach by tendons, where the enthesis is the connective tissue between the tendon and bone.
