Muscle Repair (MR) is a specialized surgical technique that restores the structural integrity of the abdominal wall. This procedure corrects a common condition where the central abdominal muscles have separated, leading to functional and aesthetic concerns. The primary purpose of MR is to bring these separated muscles back to their correct anatomical position and secure them permanently. This internal correction provides the foundation for a flatter, firmer abdomen and helps restore core strength.
Understanding Diastasis Recti
The most frequent reason for Muscle Repair is diastasis recti, involving the separation of the rectus abdominis muscles. These muscles, commonly called the “six-pack” muscles, run vertically along the front of the abdomen and are normally joined by the linea alba, a band of connective tissue. Diastasis recti occurs when this tissue stretches and weakens, creating a noticeable gap between the left and right muscle halves.
The condition is most often associated with pregnancy, as the expanding uterus places significant outward pressure on the abdominal wall. Diastasis recti can also affect men and women who have experienced substantial weight fluctuation, excess abdominal fat, or engaged in improper core exercises. The resulting muscle separation weakens the core, which can lead to functional problems.
Patients often experience a visible bulge or “pooch” in the midsection, which can become more pronounced when contracting the abdominal muscles. Beyond the aesthetic change, the compromised abdominal wall can contribute to chronic lower back pain, poor posture, and difficulty engaging the core muscles for everyday activities. The separation can also be a factor in issues like urinary incontinence, as the support structures of the trunk are diminished.
The Surgical Technique of Muscle Repair
The surgical correction of diastasis recti, often called muscle plication, involves rejoining the separated rectus abdominis muscles. The surgeon first makes an incision, typically low across the abdomen, to lift the skin and fat layer away from the underlying muscle fascia. This allows for full visualization of the muscle separation, which often runs from the lower sternum down to the pubic bone.
The repair process involves meticulously folding and suturing the stretched fascia that lies over the muscles. Strong, permanent sutures are used to bring the two halves of the rectus abdominis muscles back together at the midline. This internal tightening creates a reinforced, flat, and stable anterior abdominal wall structure.
In cases of significant separation, the surgeon may utilize a layered approach, placing multiple rows of sutures to ensure the durability of the repair. This technique effectively creates a strong, internal “corset” that physically narrows the abdominal cavity and provides long-term support. The goal is to achieve optimal tension in the repaired fascia without placing excessive pressure on the internal organs.
Procedures That Include Muscle Repair
Muscle Repair is most frequently performed as a core component of a full abdominoplasty, commonly known as a tummy tuck. While a standard abdominoplasty focuses on removing excess skin and fat, the inclusion of MR transforms it into a comprehensive procedure that addresses both aesthetic and functional issues. Not every patient undergoing a tummy tuck requires this step; MR is only performed when diastasis recti is diagnosed.
The decision to include muscle repair is based on a pre-operative physical examination and assessment of the abdominal wall. If the rectus abdominis muscles are intact or minimally lax, the muscle repair portion may be omitted. In some instances, MR may also be performed in conjunction with a complex hernia repair, as diastasis recti increases the risk of developing certain types of hernias.
The vast majority of Muscle Repair procedures are done within the context of body contouring surgery to re-establish a firm, flat abdominal profile. This internal structural correction distinguishes an abdominoplasty with MR from less invasive procedures like liposuction, which only addresses fat removal. The muscle repair step is foundational, providing the tight underlying structure necessary for the final contouring of the skin and remaining fat.
Post-Operative Recovery and Restrictions
The inclusion of Muscle Repair significantly impacts post-operative recovery, making it more restrictive than recovery from skin-only procedures. The newly repaired muscles need time to heal and securely fuse, requiring strict limitations on core strain. Patients are immediately fitted with an abdominal binder or compression garment, which must be worn continuously for several weeks to support the repair and manage swelling.
During the initial recovery phase, which typically lasts six to eight weeks, patients must avoid any activity that puts tension on the abdominal wall. This means abstaining from heavy lifting, generally defined as anything over 10 to 15 pounds, for the entire duration. Patients are also advised to avoid strenuous core exercises, such as sit-ups or crunches, for at least three to six months to prevent the internal sutures from tearing.
Discomfort is common and often described as intense muscle soreness or tightness, resulting from the newly constrained abdominal space. This internal tightening can temporarily cause a sensation of being full more quickly after eating or a decreased ability to take a deep breath. While light walking is encouraged soon after surgery to promote circulation, movement is often limited, and patients may adopt a slightly hunched posture to avoid undue strain.
