What is the main function of the joint capsule?

What is the main function of the joint capsule?

To Stabilize Joints: The joint capsule provides joint stability. If injured it can lead to stiffness and may then be surgically removed, without compromising stability as long as the joint's ligaments are kept intact. While this seems counterintuitive, it's because joints can undergo changes that turn the capsule from a necessary structure to a problem that is best removed (it regrows back more normal). ...Read more

Do all joints have a joint capsule?

Do all joints have a joint capsule?

No: A synovial joint has a capsule surrounding it. These are joints like the shoulder, knee, hip and many many others. There are also fibrous joints (like the sutures in the skull) and cartilaginous joints (like where the ribs meet the sternum). Each of these kinds of joints have numerous subtypes as well. ...Read more

Would a fx of the lateral malleolus with partially torn aftl and deltoid ligs and soft tissue injury in joint capsule be described as bimalleor?

Would a fx of the lateral malleolus with partially torn aftl and deltoid ligs and soft tissue injury in joint capsule be described as bimalleor?

Bimal equival: A single fracture of the lateral malleolus with a displaced, torn deltoid ligament can be described as a bimalleolar equivalent. It's not truly a bimalleolar fracture because there is only one "true" fracture, but because of the deltoid injury/joint displacement, it's treated as a more serious ankle fracture injury. ...Read more

Why does the anterior side of the shoulder joint capsule tear more commonly than any other side during shoulder dislocations?

Why does the anterior side of the shoulder joint capsule tear more commonly than any other side during shoulder dislocations?

Instability forces: Shoulder stability is provided by the surrounding muscles, the glenohumeral ligaments/capsule and the labrum. The shoulder is most unstable during a trauma, when the shoulder is forced anteriorly (to the front) and inferiorly (below the shoulder). This puts significant force on the anterior capsule often resulting in tearing/stretching. An abducted & externally rotated shoulder is most vulnerable ...Read more

3mm lump on epl tendon snags painfully at pip on slight flexion. Any excision risks? Fluid escape from joint capsule? Cause ganglion? Other risks?

3mm lump on epl tendon snags painfully at pip on slight flexion. Any excision risks? Fluid escape from joint capsule? Cause ganglion? Other risks?

Real cause?: Epl tendon inserts at the base of the middle phalynx so central slip snagging at pip joint is more likely a tear in fibers extending from lateral band to central slip causing abnormal shift of tendons. There is no structure that central slip [epl] would get caught on. Lump is most likely scar. Recommend splinting protocol first before considering any surgery. F/u with hand surgeon. ...Read more

Would a webr b dist fib fx with partial aftl and delt tear with some soft tissue in joint capsule and tenderness in Achilles be stable or unstable?

Ankle fracture: Weber b fracture means the level of fibula fracture starts at the ankle joint. Whether its stable or not can depend on fracture displacement, rotation, etc. In your case, you may have a bi-malleolar equivalent fracture. To determine if you need surgery or non-surgical treatment, see your podiatric surgeon. ...Read more

How long does a broken toe, torn MCL in foot, torn joint capsule and swelling in the bone take to heal?

How long does a broken toe, torn MCL in foot, torn joint capsule and swelling in the bone take to heal?

Approx 6-8 weeks.: In healthy people, most bones take 6-8 weeks to heal. However, the body continues the healing process for a full year after injury or surgery. So for example if you had an MRI it will still show activity even after the 6-8 weeks. ...Read more

Non displaced weber b fracture with partially torn deltoid and aftl ligaments and soft tissue damage in the joint capsule delayed union reasons for it

Non displaced weber b fracture with partially torn deltoid and aftl ligaments and soft tissue damage in the joint capsule delayed union reasons for it

Healing: This type of ankle fracture is a progression of a severe twisting injury to the ankle. It appears that you have had an MRI and every ankle MRI will show ligament injury. These will heal but will also be present on an MRI for a very long time. Clinical healing of a fracture happens sooner then MRI findings show healing. All fractures need 6 weeks at least for solid healing and union. ...Read more

Which are the named ligaments of the capsule of the hip joint?

Which are the named ligaments of the capsule of the hip joint?

Capsular Ligament: The capsular ligament consists of two types of fibers, circular and longitudinal. Some of the longitudinal fibers form the retinacula and the circular fibers form the zona orbicularis. It is attached to the acetabulum and anterior inferior iliac spine; and connects to the transverse ligament, iliofemoral ligament, pubocapsular, and ischiocapsular ligaments. ...Read more

Connective tissue: I believe you post is looking for either 'connective tissue', or fascia. Each joint has plent of tendinous/ligamentous support to prevent dislocation; it is when these tissues develop laxity that the dislocation occurs. ...Read more

Is the diet pill safe? I am in so much joint pain and can't sleep but losing weight will help I'm told.

Temporary fix: It depends on which pill and what your medical status is. Generally diet pills work in the short run, but without making changes in what and how much you eat, the weight will just come back on. Consider weight watchers for a good diet and moral support. Also start walking every day. It will help your joints and help you lose weight. Good luck! ...Read more

Can't sleep cuz pain on left shoulder I have osteoarthritis and just took nsaid pill what else can I do to relieve the joint pain?

Shoulder pain: Did you know that there are four joints and several muscles in your shoulder? I would suggest a visit to an orthopaedic surgeon for a musculoskeletal physical exam to determine what musculoskeletal or other cause is generating your pain. Rest, not sleeping on that shoulder, physical therapy, ice/heat, massage, NSAIDS, joint injections and surgery are potential options depending on the diagnosis. ...Read more

Mark rippetoe (a well known coach) says isotretinoin (acne pill) and weightlifting don't go hand in hand as it hurts the joints and makes skin dry? True?

Mark rippetoe (a well known coach) says isotretinoin (acne pill) and weightlifting don't go hand in hand as it hurts the joints and makes skin dry? True?

Manageable SE's: Isotretinoin, a very powerful acne medication, is a derivative of vitamin a. One of the ways that it works is by shrinking oil glands, thereby making the skin and lips very dry. It has many other potential side effects, one of which is that it can cause joint pain, especially of the large joints. This is a dose related side effect, and dose adjustments can be made to ease symptoms, as needed. ...Read more
