Hip

The hip joint is a ball-and-socket joint where the upper end (head) of the thigh bone (femur) joins with the socket (acetabulum) of the pelvis. It allows for motion and gives the stability needed to bear body weight.

The hip is the area located on each side of the pelvis. The pelvis bone is made up of 3 sections:

  1. Ilium- The broad, flaring portion of the pelvis.
  2. Pubis- The lower, rear part of the pelvis.
  3. Ischium- One of the bones that helps form the hip

 

The hip is one of the most stable joints in the body. As it bears your body weight, it is more likely to develop arthritis because of the extra pressure. Pain in the hip may be caused by injury to muscles, tendons, or the small fluid-filled sacs (bursae) that cushion and lubricate joints.

Hip Flexor Strain

WHAT IS A HIP FLEXOR STRAIN?

The hip flexors can be found connecting the top of the femur (thighbone), the largest bone in the body, to the lower back, hips, and groin.

Hip flexor muscles work together to enable a person to be mobile. They include:

  • The iliacus and psoas major muscles, also known as iliopsoas
  • The rectus femoris, which is part of a person’s quadriceps

 

These muscles and tendons are easily strained if you overuse or overstretch them, which can result in injury, accompanying pain and reduced mobility.

WHAT ARE THE SYMPTOMS OF A HIP FLEXOR STRAIN?

The primary symptom of a hip flexor strain is sudden pain at the front of the hip or pelvis.

Other common symptoms include:

  • Tenderness and a cramping or clenching sensation in the muscles of the upper leg area
  • Weakness in the front of the groin, together with a tugging sensation
  • Constant discomfort in the upper leg area
  • Swelling or bruising at your hip or thigh area
  • Muscle spasms at your hip or thigh area
  • Inability to do vigorous actions involving your hip, such as jumping or kicking
  • Worsening pain when you lift your knee toward your chest
  • Tightness or stiffness after a period of inactivity, such as waking up after sleeping

 

WHAT ARE THE CAUSES AND RISK FACTORS OF A HIP FLEXOR STRAIN?

As a person’s hip flexors are engaged when they lift their knee up towards their chest, people involved in activities such as cycling, dancing, martial arts and soccer players are at higher risk of a hip flexor strain. Athletes who run or jump a lot while performing high knee kicks are also at risk.

Hip flexor strain tears can range from mild to severe:

  • Grade I tear

Only a few fibers are damaged (minor tear)

  • Grade II tear

A significant number of muscle fibers are damaged, resulting in a moderate loss of hip flexor function

  • Grade III tear

The muscle is completely ruptured or torn, and you usually cannot walk without a limp

Most hip flexor strains are Grade II.

 

WHAT IS THE DIAGNOSIS OF A HIP FLEXOR STRAIN?

A history of the injury and a physical examination of the hip will be conducted by the Doctor.

Imaging tests will be taken, such as an x-ray and MRI scan to help the doctor rule out other possible conditions and confirm the diagnosis.

WHAT ARE THE TREATMENT OPTIONS FOR A HIP FLEXOR STRAIN?

In most cases, hip flexor strains can be treated nonsurgically with home remedies. This includes:

  • Rest

Resting the affected muscles to help them heal is important in a hip flexor strain. Avoid activities that may overstretch the muscle, such as climbing up the stairs.

  • Wearing a compression wrap

 

  • Application of ice pack/heat pack

 

  • Over-the-counter pain relief medications such as acetaminophen and ibuprofen

 

  • Gentle exercises or stretches

Exercises such as stretches or hip exercises can help strengthen your muscles and improve flexibility. These can also reduce the tension surrounding your hip, and help prevent future injury.

  • Physiotherapy

Should you have severely strained your hip flexor that it has resulted in a large muscle tear, your doctor may recommend physiotherapy. Very rarely, surgery is used to help repair the torn hip flexor.
