Hip Dysplasia and Acupuncture Treatment in Tokyo

What Is Hip Dysplasia?

Definition and Causes

Hip dysplasia is a structural abnormality where the femoral head and acetabulum are misaligned. In a healthy hip, the femoral head fits snugly into the acetabular socket, allowing smooth movement. In hip dysplasia, the socket may be too shallow, or the femoral head may be misshapen, leading to instability.

Causes of Hip Dysplasia:

1. Genetics: A family history of hip dysplasia increases the risk. Congenital DDH is often linked to genetic mutations affecting joint development.
2. Developmental Factors: In infants, improper swaddling or breech positioning in the womb can contribute to DDH.
3. Lifestyle and Activity: Repetitive high-impact activities, obesity, or poor posture may exacerbate hip dysplasia in adults.
4. Injury or Trauma: Injuries to the hip joint can alter its structure, leading to secondary dysplasia.
5. Hormonal Factors: Relaxin, a hormone released during pregnancy, can loosen ligaments, increasing the risk of hip instability.

Symptoms of Hip Dysplasia

Symptoms vary depending on the severity and age of the individual. Common signs include:

• Pain: Dull or sharp pain in the hip, groin, or lower back, especially during movement.
• Stiffness: Reduced range of motion in the hip joint.
• Limping: An uneven gait or favoring one leg while walking.
• Clicking or Popping: Audible or felt sensations in the hip during movement.
• Muscle Weakness: Weakness in the hip or thigh muscles due to compensatory movements.
• Fatigue: Discomfort may worsen with prolonged standing or activity.

In infants, signs of DDH include asymmetrical leg creases, limited leg movement, or one leg appearing shorter than the other.

Diagnosis and Conventional Treatments

Diagnosis typically involves physical exams, imaging (X-rays, MRI, or ultrasound), and assessing medical history. In infants, ultrasound is preferred due to its non-invasive nature, while X-rays are common for adults.

Conventional Treatments:

• Infants: Bracing (e.g., Pavlik harness) to hold the hip in place and promote proper development.
• Adults: Physical therapy to strengthen hip muscles, anti-inflammatory medications, or corticosteroid injections for pain relief.
• Surgical Options: Periacetabular osteotomy (PAO) to reshape the hip socket or total hip replacement for severe cases.

While effective, these treatments may not suit everyone due to invasiveness, recovery time, or side effects. This has led many to explore acupuncture as a complementary or alternative therapy.

Acupuncture: An Overview

Acupuncture is a traditional Oriental medicine (TOM) practice that involves inserting thin needles into specific points on the body, known as acupoints, to restore balance and promote healing. According to TOM, the body’s vital energy flows through meridians (energy pathways). Disruptions in Energy flow can cause pain or illness. Acupuncture aims to restore harmony by stimulating acupoints, which influence the nervous system, muscles, and connective tissues.

Modern research suggests acupuncture may work by:

• Stimulating the release of endorphins, the body’s natural painkillers.
• Modulating the nervous system to reduce pain signals.
• Improving blood flow to promote tissue repair.
• Reducing inflammation through the regulation of cytokines.

Acupuncture is widely used for musculoskeletal conditions, including hip dysplasia, due to its ability to address pain, inflammation, and mobility issues without invasive procedures.

How Acupuncture Treats Hip Dysplasia

Acupuncture offers a holistic approach to managing hip dysplasia by targeting pain, improving joint function, and addressing underlying imbalances. Here’s how it works:

1. Pain Relief

Chronic pain is a hallmark of hip dysplasia. Acupuncture stimulates the release of endorphins and serotonin, which reduce pain perception. By targeting acupoints around the hip and along related meridians, acupuncture can alleviate discomfort in the hip, groin, and lower back.

2. Reducing Inflammation

Inflammation contributes to cartilage degradation in hip dysplasia. Acupuncture may reduce pro-inflammatory cytokines, such as TNF-α and IL-6, while promoting anti-inflammatory responses. This helps decrease swelling and protect the joint from further damage.

3. Improving Mobility

Stiffness and restricted movement are common in hip dysplasia. Acupuncture enhances blood circulation to the hip joint, delivering oxygen and nutrients to tissues. This can relax tight muscles, improve flexibility, and support joint stability.

4. Supporting Muscle Strength

Weak hip muscles often accompany dysplasia due to compensatory movement patterns. Acupuncture can stimulate motor points in muscles, improving strength and coordination. This complements physical therapy by enhancing muscle activation.

5. Addressing Emotional Stress

Chronic pain can lead to stress, anxiety, or depression, which exacerbate physical symptoms. Acupuncture’s calming effect on the nervous system can reduce stress hormones like cortisol, promoting overall well-being.

Scientific Evidence

Research supports acupuncture’s efficacy for musculoskeletal pain. A 2018 meta-analysis in Pain Medicine found acupuncture effective for chronic lower back pain, which often accompanies hip dysplasia. Another study in The Journal of Alternative and Complementary Medicine (2020) reported improved hip function and reduced pain in osteoarthritis patients treated with acupuncture. While specific studies on hip dysplasia are limited, these findings suggest acupuncture’s potential for related conditions.

Key Acupoints for Hip Dysplasia

Acupuncture treatment for hip dysplasia involves selecting acupoints based on TOM principles and the patient’s symptoms. Below are key acupoints commonly used, along with their locations and benefits. These points are typically stimulated with needles, but electroacupuncture (applying a mild electrical current) or acupressure may also be used.

1. GB30 (Huantiao)

• Location: On the buttock, one-third of the way from the greater trochanter (hip bone) to the sacrum.
• Benefits: Relieves hip pain, sciatica, and lower back stiffness. Strengthens the hip joint and improves mobility.
• TOM Role: Located on the Gallbladder meridian, GB30 regulates Energy and blood flow to the hip, alleviating stagnation and pain.

2. GB29 (Juliao)

• Location: Midway between the anterior superior iliac spine (ASIS) and the greater trochanter.
• Benefits: Reduces hip joint pain, inflammation, and muscle tension. Enhances hip stability.
• TOM Role: Also on the Gallbladder meridian, GB29 clears blockages and promotes circulation to the hip.

3. BL40 (Weizhong)

• Location: At the midpoint of the popliteal crease (back of the knee).
• Benefits: Alleviates lower back and hip pain, relaxes tight muscles, and improves leg mobility.
• TOM Role: On the Bladder meridian, BL40 clears heat and dampness, reducing inflammation in the lower body.

4. ST31 (Biguan)

• Location: On the anterior thigh, below the ASIS, in a depression when the thigh is flexed.
• Benefits: Relieves hip and thigh pain, strengthens leg muscles, and improves joint function.
• TOM Role: On the Stomach meridian, ST31 activates Energy and blood flow to the lower limbs.

5. GB34 (Yanglingquan)

• Location: Below the knee, in a depression anterior and inferior to the head of the fibula.
• Benefits: Reduces muscle spasms, improves tendon flexibility, and supports joint health.
• TOM Role: Known as the “influential point for tendons,” GB34 strengthens connective tissues around the hip.

6. SP10 (Xuehai)

• Location: On the inner thigh, 2 cun (finger widths) above the superior border of the patella.
• Benefits: Enhances blood circulation, reduces inflammation, and alleviates pain in the hip and thigh.
• TOM Role: On the Spleen meridian, SP10 invigorates blood flow and clears stagnation.

7. LI4 (Hegu)

• Location: On the hand, in the webbing between the thumb and index finger.
• Benefits: Provides general pain relief, reduces stress, and supports overall Energy flow.
• TOM Role: On the Large Intestine meridian, LI4 is a powerful point for systemic pain relief and relaxation.

8. Local and Ashi Points

• Location: Tender points around the hip joint, identified during examination.
• Benefits: Directly target pain and inflammation in the affected area.
• TOM Role: Ashi points (literally “ouch” points) are used to address localized pain and stagnation.

Treatment Protocol

A typical acupuncture session for hip dysplasia involves:

1. Assessment: The acupuncturist evaluates the patient’s symptoms, medical history, and TOM diagnosis (e.g., Energy stagnation, blood deficiency).
2. Point Selection: 6–12 acupoints are chosen, combining local (hip) and distal (e.g., knee, hand) points.
3. Needle Insertion: Sterile, single-use needles are inserted to a depth of 0.5–2 inches, depending on the point.
4. Stimulation: Needles may be manually manipulated or connected to an electroacupuncture device for 20–30 minutes.
5. Frequency: 1–2 sessions per week for 6–12 weeks, depending on severity.

Electroacupuncture is particularly effective for hip dysplasia, as it enhances stimulation and promotes muscle relaxation. Patients may also receive moxibustion (burning mugwort near acupoints) to warm the area and improve circulation.
