Shoulder Impingement/Rotator Cuff Tendinitis

One of the most common physical complaints is shoulder pain. Your shoulder is made up of several joints combined with tendons and muscles that allow a great range of motion in your arm. Because so many different structures make up the shoulder, it is vulnerable to many different problems. The rotator cuff is a frequent source of pain in the shoulder.


How to use crutches, canes and walkers

If you ever break a bone in your leg or foot, have a surgical procedure on your lower limb, or suffer a stroke, you may need to use crutches, a cane, or a walker.

In the beginning, everything you do may seem difficult. But, with a few tips and some practice, you will gain confidence and learn to use your walking aid safely.


Reverse Shoulder Replacement

Reverse total shoulder replacement is a relatively new procedure for patients who have failed a previous surgery or for patients with rotator cuff tears that cannot be fixed.  

This prosthesis is appropriately named as it makes a socket out of the patient's ball, and a ball out of the patient's socket, as shown in the picture above.  Newer "reverse shoulder" prostheses make shoulder arthroplasty a reality for many patients with rotator cuff tears by reversing the positions of the components. The ball of the joint is placed in the glenoid, while the socket is positioned on the humerus.  The U.S. Food and Drug Administration began approving reverse shoulder implants in the last decade.

In patients with a traditional shoulder replacement, the rotator cuff is essential for normal motion.  When a patient has a rotator cuff tear AND arthritis, sometimes a reverse shoulder replacement is the only option.  This unique procedure has helped decrease pain and restore function for patients with this combination of difficult problems. 

Reverse shoulder replacement is not for everybody, and your surgeon must be highly trained and proficient in this technique. Dr. Bahu is specially trained in the treatment of shoulder arthritis and the use of reverse shoulder replacement. Dr. Bahu did a one year fellowship at Columbia University with one of the designers of the modern reverse shoulder replacement.

Calcium, Nutrition, and Bone Health 

Adapted from AAOS  http://orthoinfo.aaos.org/topic.cfm?topic=A00317)

The health and strength of our bones rely on a balanced diet and a steady stream of nutrients, most importantly, calcium and Vitamin D.

Calcium is a mineral that people need to build and maintain strong bones and teeth. It is also very important for other physical functions, such as muscle control and blood circulation.

Calcium is not made in the body — it must be absorbed from the foods we eat. To effectively absorb calcium from food, our bodies need Vitamin D.

If we do not have enough calcium in our diets to keep our bodies functioning, calcium is removed from where it is stored in our bones. Over time, this causes our bones to grow weaker and may lead to osteoporosis — a disorder in which bones become very fragile.

Postmenopausal women are most vulnerable to osteoporosis. Although loss of estrogen is the primary reason for this, poor lifelong calcium and Vitamin D intake, as well as lack of exercise, play a role in the development of osteoporosis.

Note that men also are at risk for osteoporosis — typically later in life than women — and it is important for them to keep track of calcium intakes, as well.


Shoulder Arthritis

Shoulder arthritis is a common cause of shoulder pain.  Patients often report "creaking and cracking" in their shoulders, as well as loss of range of motion.  Just like in hips and knees, shoulder arthritis occurs when the cartilage wears out.

Facts about shoulder arthritis

The shoulder is one of the most commonly used joints in the body and can be affected with arthritis the same way that hips and knees commonly are.


Is it a fracture or is it broken?

Despite what you may have heard, a broken bone is not worse than a fracture, they both mean the same thing. In fact, the word fracture, according to the Oxford English Dictionary is defined as "the act of being broken." 

Bones: What Kind Of Break?

Doctors talk about broken bones, also called fractures, with a few basic terms:

  • Open or closed? Closed, or simple, fractures don’t break through the skin. Open, or compound, ones do
  • Partial or complete? Partial breaks don’t go all the way through the bone. Complete breaks mean the bone is in two or more pieces
  • Displaced or non-displaced? If the broken pieces still line up, it’s a non-displaced break. If they don’t, it’s displaced

Bones: Types of Fractures

Common types of breaks include:

  • Transverse: breaks straight across the bone
  • Stress fracture: a very thin crack, also called a hairline fracture
  • Oblique: breaks at an angle
  • Greenstick: breaks on one side, but bends on the other–like a fresh stick from a tree
  • Comminuted: bone breaks into three or more pieces

Other fracture types also include:

  • a compression fracture, which often occurs in the spine
  • Spiral fractures and avulsion fractures, when a tendon or ligament pulls off a piece of bone.

Typical Bone Fractures

Treatments of Fractures

  • Internal Fixation: Hardware (plates, rods, screws...) is used to re-align and hold the bones together.
  • External Fixation: In this type of operation, metal pins or screws are placed into the broken bone above and below the fracture site. The pins or screws are connected to a metal bar outside the skin. This device is a stabilizing frame that holds the bones in the proper position while they heal.
  • Cast Immobilization: A plaster or fiberglass cast is the most common type of fracture treatment, because most broken bones can heal successfully once they have been re-positioned and a cast has been applied to keep the broken ends in proper position while they heal.
