Some issues Dr. Zachariah Summers Logan, MD can help you with:

Hip Replacement

Hip replacement is a surgical procedure to replace parts of the hip joint that are damaged by disease or injury. It is most often done to treat arthritis, a common condition that causes stiffness and pain in the joints. Surgery is used only after other, less invasive treatments have failed to work.

The type of hip replacement patients receive is based on their age and the extent of damage to their hip. The hip joint has two parts: the femoral head, or hip ball, and the acetabulum, or hip socket. The hip ball is located on the upper end of the femur (thigh bone), and the hip socket is part of the pelvis. Depending on whether one or both parts require replacement, patients may need one of the following procedures:

Partial hip replacement, which is generally recommended in the case of hip fractures or other hip injuries. If a patient is having a partial hip replacement, only the hip ball will be replaced.
Total hip replacement, which is often used to treat the hip joint when it has become damaged due to arthritis. Both the hip socket and hip ball are replaced.
Hip resurfacing, which is usually performed for younger patients. A hip resurfacing procedure reshapes the hip ball and only replaces its surface. This preserves more bone and makes future surgeries easier. If a patient is having a partial hip resurfacing, only the hip ball is resurfaced and replaced. If a patient is having a total hip resurfacing, the hip socket will be replaced as well.

During hip replacement surgery, an incision is made along the side of the hip. The surgeon may access the joint directly through this incision, or by using small tools and a lighted tube called an arthroscope to see and treat the joint. The diseased tissue is removed, and the bones are smoothed out and fitted with metal ends. The metal pieces may be cemented in place, or they may have a porous structure that encourages bone to grow into them and hold them securely. A smooth plastic cushion is placed between the two bones to replace the cartilage and allow the joint to move freely.

Hip replacement surgery takes one to two hours, and afterwards patients may stay in the hospital for several days. When patients go home, they will have to use a cane, walker, or crutches at first. Patients will likely have physical therapy to improve their ability to move with their new hip. After the first few weeks, light exercise such as bike riding or swimming will help them heal, but certain actions, such as climbing stairs or bending over at the waist, may be difficult at first. It will take several weeks before they can drive or return to work. Full recovery may take six to 12 months.

Musculoskeletal Problems

The musculoskeletal system refers collectively to the bones, joints, ligaments, muscles, and nerves. It is what gives the body structure and movement. Because this system encompasses so much of the body, musculoskeletal problems are extremely varied and can happen almost anywhere. There are musculoskeletal problems that affect only the joints, those that affect the bones, those that affect tendons and ligaments, and those that can happen in any area of the body but cause pain and numbness.

Joint problems include bursitis and arthritis. Bursitis is the inflammation of a fluid-filled sac cushion on the outside of a joint, causing symptoms including pain and swelling. Arthritis is the inflammation and damage of a joint due to wear and tear or disease. There are several treatments for arthritis, but if the damage progresses far enough, joint replacement may be necessary. In joint replacement, a metal or plastic implant is surgically placed within the joint to make movement easier.

Bone problems include scoliosis, fractures, and osteoporosis. Scoliosis is a curvature of the spine, making the normally straight spine look like a 'C' or 'S.' It is treated with braces or surgery. Osteoporosis is a disease that causes bones to weaken and break easily. It's most common in women, especially older women. Fully half of all women over 65 have osteoporosis. Fractures are any break in the bone. They can be a simple crack or a severe and complicated shatter. Osteoporosis causes fractures in people who have it, but other causes are trauma (such as a fall) or overuse.

Tendon and ligament problems most often result from injury or overuse. Two good examples are ligament tears and tendonitis. The most common ligament tear is the ACL tear in the knee. This ligament supports and stabilizes the knee and is most often torn during sports activities. Tendonitis happens when a tendon, which connects muscles and bones together, becomes irritated and inflamed. This happens most often in older patients who push their bodies too far, leading to pain and swelling. Treatment for both tendon and ligament problems usually includes rest, ice, and supporting the area to let it heal.

Pain and numbness problems can be caused by overuse, disease, an injury, or a compressed nerve. Lower back pain and carpal tunnel syndrome are two of the most common conditions patients encounter. Lower back pain may be caused by sore muscles that have been overworked, or an injury to the disks separating the vertebrae in the spine. Lower back pain usually goes away on its own within a few days, but it may require medical treatment depending on the cause. Carpal tunnel syndrome occurs when the nerve at the base of the palm becomes trapped or pinched. Symptoms include tingling, pain, numbness, or weakness in the hand. Treatment involves rest and sometimes steroid injections.

Because the musculoskeletal system involves so much of the body, problems here can be incredibly varied in their type and severity. Some musculoskeletal problems will go away on their own or only require rest, while others may require medication, physical therapy, or even surgery.

Replacement Arthroplasty (Joint Replacement)

Joint replacement, sometimes also called arthroplasty, is an option when a joint becomes severely damaged by disease or injury. The damaged cartilage of the joint is surgically removed, the ends of the bones in the joint are resurfaced, and a prosthetic is installed. Most prosthetic joints are made of a metal piece that fits into a plastic sleeve so that they glide smoothly. A joint replacement increases stability in the damaged area and decreases pain. The hip and knee are the two joints most commonly replaced, but joint replacement can also be performed on the ankle, shoulder, elbow and even fingers.

Although joint replacement is one of the safest and most reliable medical procedures available, it is still a major surgical procedure. All surgical procedures carry risks, such as infection or blood clots. For this reason, doctors try to help their patients avoid surgery for as long as they can. Taking arthritis medications, losing weight, avoiding high impact sports such as running, taking supplements such as glucosamine or chondroitin, or having joint injections may allow a patient to enjoy life without the need for surgery.

After having joint replacement surgery, patients can expect some pain the first few days as they recover. Physical therapy is an important part of recovery, and it can decrease complications and increase future mobility. As soon as possible, returning to low impact sports such as swimming, walking or biking can stretch and heal the new joint. A prosthetic joint can last 15 - 20 years and cannot be further damaged by degenerative diseases such as arthritis, so once it is done patients should be pain-free for many years.
