Some issues Dr. John Thaddeus Decker, MD can help you with:

Hysterectomy (Uterus Removal)

A hysterectomy is an extremely common surgery performed to remove the uterus. Sometimes the fallopian tubes, ovaries, or cervix will be removed as well. A woman who has had a hysterectomy will no longer have periods and cannot get pregnant.

There are a variety of reasons that women have hysterectomies, including:

Heavy bleeding or pain, such as that due to fibroids, endometriosis, or adenomyosis
Cancer
Prolapsed uterus, where the pelvic muscles can no longer completely hold the uterus in place

It is important to note that having any of these conditions does not necessarily mean that a hysterectomy is necessary. There are other available treatment options in most cases.

Although the uterus is responsible for a period, it is the ovaries that control the hormonal changes that women go through every month. So if a woman has a hysterectomy but keeps her ovaries, she might still experience hormonal swings every month even if she no longer has a period. Alternately, if a younger woman has a hysterectomy where her ovaries as removed, she will essentially be in immediate menopause.

A hysterectomy can be performed traditionally through one large cut in the abdomen, laparoscopically using tiny incisions and small tools, or through the vagina. Full recovery may take four to six weeks. After a hysterectomy, patients might experience sexual changes such as vaginal dryness or a change in libido. It is common to experience strong emotions after a hysterectomy, including both grief and relief. If a patient's ovaries were removed, they may be at higher risk for certain diseases, such as heart disease and osteoporosis. Taking hormonal birth control might reduce this risk.

Spinal Cord Injury

Spinal cord injury medicine is a branch of medicine that treats damage to the spinal cord from an injury or a nontraumatic myelopathy, which is any disorder that affects the spinal area. The spinal cord is a section of nerve tissue protected by the vertebrae (spinal bones). Trauma to the spinal cord, typically caused by compression or bent vertebrae, prevents the body and brain from communicating. This can result in pain, loss of sensation, and impaired physical function and movement. Acute spinal cord injuries (SCIs) are a leading cause of permanent disability. Spinal cord injuries may develop from accidents or myelopathies, disorders that provoke spinal compression. Traumatic incidents such as falls, sports injuries, vehicle accidents, and bullet or stab wounds can cause an acute spinal cord injury.

Spinal cord injury medicine seeks to stabilize the spine and to alleviate the symptoms of spine damage. Practitioners of spinal cord injury medicine are called spinal cord injury specialists. Spinal cord injury medicine is an interdisciplinary field, meaning physicians of various specialties may be trained to treat spinal cord injuries.

Damage to the spinal cord may initially be diagnosed through X-ray, MRI, or CT scans. Patients can also undergo spinal exams to evaluate their sensory ability and strength. Injuries to the spinal cord can be complete (no feeling or sensation) or incomplete (some feeling or sensation remains). Conditions spinal cord injury medicine specialists may treat include:

Paralysis, such as paraplegia (loss of function in the legs), or quadriplegia (loss of function from the neck down)
Spine fracture or trauma, which can lead to impairment and/or significant pain
Spinal infections
Myelopathies, such as herniated disks, spinal tumors, and rheumatoid arthritis
Inflammatory diseases such as ankylosing spondylosis, and degenerative conditions like Lou Gehrig's disease (ALS)

Treatment for spinal cord injuries often involves surgery, either directly after an injury occurs or at a later date. Surgery for spine injuries is intended to ease spinal compression and stabilize the spine. Surgical procedures can involve shifting vertebrae, removing bone, or altering spinal placement with implantable devices. Patients with significant spinal trauma may require urgent surgical intervention.

Surgical treatments can be complemented by rehabilitative physical therapy to improve mobility. Spinal cord injury specialists also treat complications arising from a spinal injury, such as respiratory or bladder conditions. Some patients with spinal cord injuries may require lifelong treatment. Spinal cord injury specialists aim to help these patients successfully adjust and lead an improved quality of life. An emerging treatment for spinal cord injuries is neural prosthetics, which replicate patients' lost nerve function. Neural prostheses may be used as artificial body parts or assistive devices that patients may cognitively control. Other assistive devices include wheelchairs and scooters.

Spinal cord injury specialists may collaborate with physical therapists, radiologists, neurologists, urologists, and orthopedists.
