The hip joint consists of the top of the femur and the acetabulum of the pelvis. Both joint surfaces are covered with articular cartilage. This ball and socket joint has movement in multiple directions (i.e. flexion/extension, abduction/adduction, internal/external rotation), but it is also quite stable. The labrum increases the depth of the acetabulum, which in turn creates increased security of the femur. The primary function of the hip joint is to support the body during static and dynamic positions.

It is uncommon that the hip is injured through acute trauma and typically pain is from degenerative joint disease or an inflammatory process like bursitis. Low back disorders can mimic hip disease, so the low back needs to be cleared before treating the hip. Hip disease can lead to low back issues due to the biomechanical relationship between the two areas.

Some common disorders at the hip are trochanteric bursitis, muscle strains, labral tears and arthritis.

• Trochanteric Bursitis is occurs in the lateral (outside) region of the hip and can radiate down the lateral aspect of the thigh to the knee. A person with trochanteric bursitis will have pain with ascending stairs and lying on the involved side. The pain is typically deep and aching. Treatment would involve avoiding the irritating positions, use of ice, soft tissue mobilization, ultrasound, stretching, non steroidal medications (Aleve and Advil), and strengthening. A cortisone shot is usually very helpful to eliminate the pain and inflammation.
• Muscle strains typically occur at the weakest link of the muscle-tendon unit. The musculotendinous junction may give way or the bony attachment may be damaged when increased stress is applied to an area. The most common hip muscles that are strained are the hamstrings and rectus femoris, however it is not uncommon to have injury to the adductors or the iliacus. Treatment involves ice, ultrasound, and gentle stretching initially. As healing occurs soft tissue mobilization and strengthening are added to the program. Specific examples of hip stretching and strengthening are:
  • Degenerative joint disease (Hip Arthritis) has various causes from injury to genetics. Symptoms present as pain in the hip area and most often the groin that can radiate down the leg and into the low back. Ambulation, standing, and squatting can be painful. People with arthritis of the hip benefit from soft tissue mobilization, joint mobilization, stretching, strengthening, gait training and wearing supportive shoes. Lubricating injections and cortisone can be helpful. If the symptoms become too severe and have limited the person’s ability to complete daily activities surgery is the next option. We recommend Yoga, Pilates, pool exercises and other forms of stretching and strengthening for all hip arthritis patients.
  • In the younger populations there are two disorders that can occur at the hip. The first one is Legg Calve’ Perthe Disease. The femoral head becomes flattened which results in decreased hip range of motion. There is no known cause but typically occurs in young, active people. The child will complain of pain in the inner thigh and knee. The common treatment for this disorder is stretching, strengthening, and bracing.
  • The second disorder occurs in overweight boys during a period of rapid growth. This condition is called Slipped Capital Femoral Epiphysis. The head of the femur becomes displaced from its normal position. The treatment is surgery with rehabilitation to follow.

To help protect your hip it is wise to be on a daily stretching program and a strengthening program seven days a week. Beneficial stretches would be for the hamstrings, quadriceps, and gluteals. Strengthening exercises should focus on the gluteals, hamstrings. Some suggestions are bridging, foot on ball bridging with alternating arm reaches, squats, side steps with a theraband around the ankles, and single leg balance.
