Q: Frog Legs: A Guide to Hip Joint Measurement and Diagnosis

Hello, sir： Thank you for your inquiry. <br>In response to your question, the inability to squat may be related to issues with the frog leg position and the ankle joints, and a clinic examination is necessary to determine the cause. <br>Wishing you safety and happiness.

Regarding frog legs?

Hello Dr.
Yeh.
I previously visited an orthopedic doctor due to issues with my inability to squat during military service physical examinations.
At that time, the diagnosis was commonly referred to as "frog leg," which indicates symptoms of gluteal muscle fibrosis.
I requested a medical certificate, but it did not include any angles.
Later, I learned that an angle measurement is necessary to apply for a re-examination.
During my second visit to the doctor, I asked him to measure my hip joint angle, but he did not perform the measurement.
Instead, he used a method from the military service posture manual to measure with one leg, but he said that this method would easily show an angle exceeding 120 degrees.
However, I saw you mention that with "frog leg," it should not exceed 90 degrees.
I would like to ask whether the measurement method was incorrect or if I do not actually have "frog leg." I personally cannot squat; after just a few seconds of squatting, my legs become very sore, and my heels cannot touch the ground.

More Info

Understanding the condition known as "Frog Legs," or gluteal muscle fibrosis, involves a comprehensive approach to diagnosis and treatment. This condition is characterized by a limitation in the range of motion of the hip joint, particularly in the ability to squat or bend the knees without discomfort. The symptoms you describe, including difficulty squatting and experiencing pain or discomfort in the hips, are indicative of potential underlying issues related to muscle tightness or structural abnormalities.

Diagnosis
To accurately diagnose gluteal muscle fibrosis, a thorough physical examination is essential. This typically includes:
1. Range of Motion Assessment: A healthcare provider will assess the hip joint's range of motion, particularly focusing on flexion, abduction, and internal/external rotation. The standard measurement for hip flexion should ideally be above 120 degrees. If you are unable to achieve this, it may suggest a restriction due to fibrosis or other muscular issues.

2. Functional Tests: Tests such as the single-leg squat or the ability to perform a deep squat can provide insight into the functional limitations caused by the condition. If you experience significant discomfort or are unable to maintain the squat position, this further supports the diagnosis of gluteal muscle fibrosis.

3. Imaging Studies: While X-rays can help rule out bone-related issues, they are not particularly useful for soft tissue evaluation. An MRI may be more beneficial in assessing the condition of the muscles and identifying any fibrosis or other abnormalities.

4. Differential Diagnosis: It is crucial to differentiate between gluteal muscle fibrosis and other conditions such as piriformis syndrome or hip joint pathologies. Each of these conditions has distinct characteristics and treatment approaches.

Treatment
Once a diagnosis is established, treatment options may include:
1. Physical Therapy: Engaging in a structured physical therapy program can help improve flexibility, strength, and overall function of the hip joint. A physical therapist can provide targeted exercises to stretch the gluteal muscles and strengthen the surrounding musculature.

2. Manual Therapy: Techniques such as myofascial release or deep tissue massage may help alleviate tightness in the gluteal region and improve mobility.

3. Stretching and Strengthening Exercises: Incorporating specific stretching routines for the hip flexors, hamstrings, and gluteal muscles can be beneficial. Strengthening exercises for the core and lower extremities can also help support the hip joint and improve overall stability.

4. Activity Modification: Avoiding activities that exacerbate the symptoms, such as deep squatting or prolonged sitting, can help manage pain and prevent further injury.

5. Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) may be recommended to manage pain and inflammation associated with the condition.

6. Surgical Intervention: In rare cases where conservative measures fail, surgical options may be considered to release tight muscles or repair any structural abnormalities.

Conclusion
In summary, the diagnosis of "Frog Legs" or gluteal muscle fibrosis requires a detailed assessment of hip joint function and range of motion. If you are experiencing significant limitations in your ability to squat or perform daily activities, it is advisable to seek a thorough evaluation from a qualified healthcare provider. They can guide you through the appropriate diagnostic tests and develop a tailored treatment plan to address your specific needs. Remember, early intervention can significantly improve outcomes and enhance your quality of life.
