What is a Sports Hernia?
Sports hernia does not fit the common definition of a “hernia,” where an organ or soft tissue protrudes outside its normal cavity. There is no defect in the abdominal wall or herniation of the abdominal contents with a sports hernia. Injury occurs in the form of tears and weakening in the deep layers of the abdominal wall. Other common terms for a sports hernia include “sportsman’s hernia” and “hockey groin.”
Repetitive hip and pelvic motions typical in sports can cause injury to the lower abdominal area. Imbalances between the hip and abdominal muscles can, over time, cause overuse and injury. Weakness and lack of conditioning in the abdominals also might contribute to the injury. Ironically, aggressive and unsafe abdominal exercise programs can also cause or aggravate a sports hernia. A sports hernia usually occurs where the abdominal muscles attach in your pelvis. There is no protrusion of organs in a sports hernia, but there are tears in tendons and muscles, such as those surrounding the hip. This makes the term “hernia” a misnomer, as the term hernia means when organs from your abdomen come out through spaces, such as the inguinal canal. Nerve irritation can also occur with a sports hernia, contributing to the uncomfortable symptoms.
How Does it Feel?
Chronic groin pain is a hallmark symptom of sports hernia. It occurs in 5% to 18% of athletes, and varies with the sport being played. Sharp groin pain with exertion is also a typical symptom. Pain often occurs exclusively with intense sprinting, kicking, twisting, or “cutting,” and subsides rapidly with rest. Significant training and competition time can be lost due to the chronic groin pain caused by sports hernia.
With sports hernia you may experience:
Sharp or stabbing pain in the groin region that occurs mainly with running, sprinting, cutting, pivoting, kicking, or twisting.
Pain felt while performing abdominal sit-ups.
Pain that is often isolated to 1 side of the groin.
Pain that radiates into the inner thigh.
Pain isolated to the groin when coughing or sneezing.
Minimal to no pain in the groin when resting, sitting, or sleeping.
Tenderness to touch or pressure on the lower abdominal area.
Note: If you have groin pain that isn’t relieved with rest from activity, you could have other potentially serious medical conditions involving the digestive, urinary, or reproductive systems. Consult your physician.
How Is It Diagnosed?
If you see your physical therapist first, your therapist will conduct a thorough evaluation that includes taking your health history. Your therapist may ask whether you:
Have groin pain that occurs when you are sprinting, twisting, or kicking.
Have had any injuries to your hip, low back, or groin.
Have recently completed any intense abdominal or core strengthening exercises.
Get relief from your groin pain if you rest or don’t participate in your regular sport or exercise routine.
Feel pain in your groin when coughing, sneezing, or “bearing down.”
Recall a particular movement or incident when you first felt pain in the area.
Experience groin pain that limits your desired level of sport performance.
Your physical therapist also will conduct standard strength tests of your hip muscles, and tests to measure the flexibility of your hip and thigh muscles. Your physical therapist will assess how well you can isolate or contract certain muscles. A thorough examination of your hip and low back movements may also be performed.
Your physical therapist may use additional tests to investigate for knee joint or lumbar spine injuries.
To provide a definitive diagnosis, your physical therapist may collaborate with a sports medicine physician or other health care provider. The physician may order further tests—such as magnetic resonance imaging (MRI) — to rule out other injuries to your hip, low back, or pelvis, and further confirm the diagnosis of sports hernia.
How Can a Physical Therapist Help?
Conservative treatment of sports hernia includes rest and physical therapy. Your physical therapist will provide treatments to target the key problems found during the examination. Your therapist will design an individualized treatment program for you that targets your condition and goals, to help you safely return to your sport or normal activity levels.
Some cases of more severe injury may require surgery. Most patients with a sports hernia are advised to first attempt a conservative course of treatment for 4 to 6 weeks. If groin pain continues to occur after that time, surgery may be recommended. If you decide to have surgery, your therapist can help you regain your strength and flexibility following the procedure.
Treatment Without Surgery
Physical therapy will focus on addressing the key problems that are found during your evaluation. The key issues that are often found with a sports hernia include poor hip strength and flexibility, and a reduced ability to activate or turn the abdominal muscles to stabilize the pelvis.
Targeted physical therapy treatments will address your condition without worsening or reproducing your pain.
Your physical therapist will also caution you to avoid certain activities and exercises that cause groin pain. Ice may also be applied to decrease pain in the area of injury. Your therapist may advise you to:
Avoid aggressive or painful stretching.
Avoid stretching your trunk and upper body.
Avoid doing sit-ups.
Your physical therapy treatment may include:
Icing and compression. During the initial phases of injury or when high levels of pain are being experienced, application of ice to the area may decrease pain levels.
Stretching. Your physical therapist may help you perform hip and low back exercises to gently stretch and strengthen your muscles. Your therapist will educate you on the proper duration and frequency of exercises to improve muscle flexibility and decrease pain.
Muscle retraining.Your physical therapist will teach you to target or activate the abdominal and hip muscles. This is a key part of your treatment; certain muscles may not be “firing” or contracting due to pain and inhibition.
Strengthening.Targeted hip strengthening and nonaggravating core strengthening will be started once you are no longer experiencing pain.
Manual therapy. Hands-on stretching, soft-tissue mobilization, and joint mobilization may be performed by your physical therapist based on your evaluation.Manual (hands-on) therapy may be performed to improve your hip-joint mobility and range of motion, or ease muscle pain and improve flexibility.
Return-to-sport drills. Once you are able to progress without pain during treatment, your physical therapist will add movements specific to your sport or activity into your treatment program.For instance, you may return to running and light sport drills to prepare your body for the stress of full participation in your sport.
Can this Injury or Condition be Prevented?
Sports hernia is a challenging condition to prevent because of the inherent stress and strain placed on the pelvis and hips during certain sports. That being said, a prevention program should be directed at those at the highest risk—males participating in soccer, hockey, and football. That program includes:
Abdominal and core stabilization exercises
Exercises to strengthen the hip adductor muscle
Exercises to help decrease stress across the pelvis and lower abdominal area, where the sports hernia injury often occurs
Real Life Experiences
Mitch is a high-school soccer player who has been experiencing left-sided groin pain over the past month. He has been trying to play this season, but experiences sharp groin pain when kicking the ball, twisting to defend his opponents, and sprinting. He has sat out 2 practices and 1 game, but his pain starts up again as soon as he tries to play. He can run with no pain, but is frustrated because he can’t kick the ball as far or as hard as he once did. His dad calls his physical therapist.
Mitch’s physical therapist, upon hearing his account of his recent pain, and conducting a hands-on examination, determines that Mitch is experiencing the signs and symptoms consistent with a sports hernia. She recommends that Mitch receive conservative nonsurgical treatment for 4 weeks. She designs a treatment program that includes manual therapy and exercises targeted at his hip muscles to improve their strength and flexibility. She also teaches Mitch how to isolate his deep abdominal muscles, and help stabilize his pelvis with gentle soccer-specific kicking motions. During his treatment sessions, she also tells Mitch what exercises and activities to avoid, including sit-ups.
During the last phase of his treatment program, Mitch starts to run and perform drills to replicate movements similar to soccer, and prepare his body for the stress of rejoining the team.
After 6 weeks of treatment, Mitch is cleared by his physical therapist and physician to resume soccer practice—and is able to kick and play without any pain or limitations.
