The sacroiliac joint is a paired joint in the pelvis that lies between the sacrum and an ilium. Due to its location in the lower back, a dysfunctional sacroiliac joint may cause lower back and/or leg pain. The resulting leg pain can be severe, resembling sciatica or a slipped disc. While nonsurgical treatments are effective for some, others have found that surgery for the dysfunctional sacroiliac joint is the only method to relieve pain.
Sacroiliac joint dysfunction is diagnosed by a physician. Associated surgery should only occur when certain criteria are satisfied. [1] Surgical options, such as the degree of invasiveness, can then be evaluated when deciding on a treatment plan.
If complications occur, they are often detected early (during surgery or shortly after) and correlate with the surgical approach. [2] [3] [4] [5] Results and outcomes vary according to the patient, pathology, surgeon, procedure, and methods. [5]
Sacroiliac joint surgery was first described in 1926 by the Journal of Bone and Joint Surgery. [6] Following its appearance, the original procedure was documented in several publications and practices for nearly a century. [2] [3] [4] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [ excessive citations ]
Sacroiliac joint surgeries have improved significantly beyond their nascency, which lacked the advent of hardware or instrumentation. [6] The first use of sacroiliac joint surgical materials appeared in 1987 with the use of ceramic blocks to aid in joint fusing. [7] The year 2001 marked the advent of spinal rods and screws to facilitate internal fixation. [8] Continued improvements have been documented as surgeons reduce their incision size while avoiding tissues such as muscle, blood vessels, and nerves. [3] [6] Modern sacroiliac joint surgery utilizes instrumentation systems attempts to be as minimally invasive as possible.[ citation needed ]
The first surgical textbook on sacroiliac joint surgery was published in 2014. [5]
The diagnosis of dysfunctional sacroiliac joint results from a combination of patient history, [1] clinical evaluation, [1] [5] [18] and one or more injections. [1] [5] [18] [19] The gold standard diagnostic injection utilizes a long-acting anesthetic agent with radiographic dye. [5] A diagnosis can be made following injections into the posterior sacroiliac transverse ligament. [1] [3] [5]
Currently, there is no standard treatment regimen that must precede sacroiliac joint surgery. However, an algorithm has been designed (2010) to guide the treatment process before committing a patient to surgery. [1] This algorithm allows for the use of alternative treatments (prolotherapy, radio frequency neural ablation, cryotherapy, acupuncture, and others) if desired by a clinician or patient.[ citation needed ]
When preparing to fuse the sacroiliac joint, a surgeon must consider the desired degree of invasiveness, surgical approach (fascial splitting that is posterior midline, posterior lateral, posterior lateral inferior, lateral, anterior), instrumentation, type of bone grafting material (autograft, allograft, and xenograft), and type of bone graft enhancing material (bone morphogenetic proteins). [5] Another consideration is a patient's desired postoperative weight bearing status, as some procedures result in full weight bearing while others only partial.[ citation needed ]
Current diagnostic criteria (not standard but generally accepted) include at least 6 months of chronic pain, failure of previous treatments, disability from daily activities, and a diagnostic injection. [5] There is no current standard operating procedure, [5] though some surgeons may prefer an approach based on his or her training and exposure (there are exceptions). [5]
The most frequently practiced fusion procedure is the lateral minimally invasive approach. [5] One leading explanation for this involves the FDA having made possible a Premarket notification (510(k)) for instrumentation that has a predicate preceding 1976. Several lateral minimally invasive instrumentation systems have acquired this designation. [5] [20] Some procedures are unique in that they do not rely on a fusion of the joint. [13]
Recent research by Guentchev et al. 2017 shows that peripheral nerve stimulation is a successful long-term therapy for degenerative sacroiliitis in older patients. [21]
Operating on a dysfunctional sacroiliac joint is an elective procedure and should never be an emergency. Preoperative planning and preparation should prevent or lessen the likelihood of most complications. However, aside from the general complications that encompass any reconstructive surgery, specific complications are associated with the sacroiliac joint.[ citation needed ]
The sacroiliac joint is essentially halfway between the ventral and dorsal sides of the body deep within the pelvis, a location in close proximity to several vital structures. Those structures within a few centimeters of the sacroiliac joint include the sacrum, ilium, sciatic nerve, dorsal and ventral sacral nerves, lumbar plexus, superior gluteal artery, iliac vessels, and large intestine. [5] While these structures could be injured during any type of sacroiliac joint procedure, the lateral minimally invasive approach is associated with the greatest number of complications. [4] [5]
Surgical outcome following dysfunctional sacroiliac joint correction has yet to be evaluated by multi-center studies. Multiple peer-reviewed articles have conducted followups, describing an overall success or satisfaction rate in the 70-80% range. [3] [4] [9] [10] [11] [12] [14] [15] [16] [17] However, one article was suggestive of poor outcomes with only 18% of patients being satisfied. [2]
Surgery has been demonstrated to also be effective for some pathologies that involve sacroiliac joint dysfunction. [5] The one exception is inflammatory arthritis, for which surgery achieves mixed results. [5]
Surgeries for the dysfunctional sacroiliac joint are currently in their infancy, despite their many advances. Prospective and multi-center studies are needed to move this surgery into the knowledge base of surgical education and surgical societies. [22] Advancements in surgery are expected to continue as science is applied further to the diagnosis and treatment of sacroiliac joint dysfunction.[ citation needed ]
A laminectomy is a surgical procedure that removes a portion of a vertebra called the lamina, which is the roof of the spinal canal. It is a major spine operation with residual scar tissue and may result in postlaminectomy syndrome. Depending on the problem, more conservative treatments may be viable.
The sacroiliac joint or SI joint (SIJ) is the joint between the sacrum and the ilium bones of the pelvis, which are connected by strong ligaments. In humans, the sacrum supports the spine and is supported in turn by an ilium on each side. The joint is strong, supporting the entire weight of the upper body. It is a synovial plane joint with irregular elevations and depressions that produce interlocking of the two bones. The human body has two sacroiliac joints, one on the left and one on the right, that often match each other but are highly variable from person to person.
Spondylosis is the degeneration of the vertebral column from any cause. In the more narrow sense it refers to spinal osteoarthritis, the age-related wear and tear of the spinal column, which is the most common cause of spondylosis. The degenerative process in osteoarthritis chiefly affects the vertebral bodies, the neural foramina and the facet joints. If severe, it may cause pressure on the spinal cord or nerve roots with subsequent sensory or motor disturbances, such as pain, paresthesia, imbalance, and muscle weakness in the limbs.
The Maisonneuve fracture is a spiral fracture of the proximal third of the fibula associated with a tear of the distal tibiofibular syndesmosis and the interosseous membrane. There is an associated fracture of the medial malleolus or rupture of the deep deltoid ligament of the ankle. This type of injury can be difficult to detect.
Sacroiliitis is inflammation within the sacroiliac joint. It is a feature of spondyloarthropathies, such as axial spondyloarthritis, psoriatic arthritis, reactive arthritis or arthritis related to inflammatory bowel diseases, including ulcerative colitis or Crohn's disease. It is also the most common presentation of arthritis from brucellosis.
Spinal fusion, also called spondylodesis or spondylosyndesis, is a neurosurgical or orthopedic surgical technique that joins two or more vertebrae. This procedure can be performed at any level in the spine and prevents any movement between the fused vertebrae. There are many types of spinal fusion and each technique involves using bone grafting—either from the patient (autograft), donor (allograft), or artificial bone substitutes—to help the bones heal together. Additional hardware is often used to hold the bones in place while the graft fuses the two vertebrae together. The placement of hardware can be guided by fluoroscopy, navigation systems, or robotics.
Failed back syndrome or post-laminectomy syndrome is a condition characterized by chronic pain following back surgeries. Many factors can contribute to the onset or development of FBS, including residual or recurrent spinal disc herniation, persistent post-operative pressure on a spinal nerve, altered joint mobility, joint hypermobility with instability, scar tissue (fibrosis), depression, anxiety, sleeplessness, spinal muscular deconditioning and even Cutibacterium acnes infection. An individual may be predisposed to the development of FBS due to systemic disorders such as diabetes, autoimmune disease and peripheral blood vessels (vascular) disease.
Scheuermann's disease is a self-limiting skeletal disorder of childhood. Scheuermann's disease describes a condition where the vertebrae grow unevenly with respect to the sagittal plane; that is, the posterior angle is often greater than the anterior. This uneven growth results in the signature "wedging" shape of the vertebrae, causing kyphosis. It is named after Danish surgeon Holger Scheuermann.
The superior cluneal nerves are pure sensory nerves that innervate the skin of the upper part of the buttocks. They are the terminal ends of the L1-L3 spinal nerve dorsal rami lateral branches. They are one of three different types of cluneal nerves. They travel inferiorly through multiple layers of muscles, then traverse osteofibrous tunnels between the thoracolumbar fascia and iliac crest.
A laminotomy is an orthopaedic neurosurgical procedure that removes part of the lamina of a vertebral arch in order to relieve pressure in the vertebral canal. A laminotomy is less invasive than conventional vertebral column surgery techniques, such as laminectomy because it leaves more ligaments and muscles attached to the spinous process intact and it requires removing less bone from the vertebra. As a result, laminotomies typically have a faster recovery time and result in fewer postoperative complications. Nevertheless, possible risks can occur during or after the procedure like infection, hematomas, and dural tears. Laminotomies are commonly performed as treatment for lumbar spinal stenosis and herniated disks. MRI and CT scans are often used pre- and post surgery to determine if the procedure was successful.
Unicompartmental knee arthroplasty (UKA) is a surgical procedure used to relieve arthritis in one of the knee compartments in which the damaged parts of the knee are replaced. UKA surgery may reduce post-operative pain and have a shorter recovery period than a total knee replacement procedure, particularly in people over 75 years of age. Moreover, UKAs may require a smaller incision, less tissue damage, and faster recovery times.

The term sacroiliac joint dysfunction refers to abnormal motion in the sacroiliac joint, either too much motion or too little motion, that causes pain in this region.
Posterolateral corner injuries of the knee are injuries to a complex area formed by the interaction of multiple structures. Injuries to the posterolateral corner can be debilitating to the person and require recognition and treatment to avoid long term consequences. Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). As with any injury, an understanding of the anatomy and functional interactions of the posterolateral corner is important to diagnosing and treating the injury.
Limb-sparing techniques, also known as limb-saving or limb-salvage techniques, are performed in order to preserve the look and function of limbs. Limb-sparing techniques are used to preserve limbs affected by trauma, arthritis, cancers such as high-grade bone sarcomas, and vascular conditions such as diabetic foot ulcers. As the techniques for chemotherapy, radiation, and diagnostic modalities improve, there has been a trend toward limb-sparing procedures to avoid amputation, which has been associated with a lower 5-year survival rate and cost-effectiveness compared to limb salvage in the long-run. There are many different types of limb-sparing techniques, including arthrodesis, arthroplasty, endoprosthetic reconstruction, various types of implants, rotationplasty, osseointegration limb replacement, fasciotomy, and revascularization.
Minimally invasive spine surgery, also known as MISS, has no specific meaning or definition. It implies a lack of severe surgical invasion. The older style of open-spine surgery for a relatively small disc problem used to require a 5-6 inch incision and a month in the hospital. MISS techniques utilize more modern technology, advanced imaging techniques and special medical equipment to reduce tissue trauma, bleeding, radiation exposure, infection risk, and decreased hospital stays by minimizing the size of the incision. Modern endoscopic procedures can be done through a 2 to 5 mm skin opening. By contrast, procedures done with a microscope require skin openings of approximately one inch, or more.
Wrist osteoarthritis is a group of mechanical abnormalities resulting in joint destruction, which can occur in the wrist. These abnormalities include degeneration of cartilage and hypertrophic bone changes, which can lead to pain, swelling and loss of function. Osteoarthritis of the wrist is one of the most common conditions seen by hand surgeons.
Trapeziometacarpal osteoarthritis (TMC OA) is, also known as osteoarthritis at the base of the thumb, thumb carpometacarpal osteoarthritis, basilar (or basal) joint arthritis, or as rhizarthrosis. This joint is formed by the trapezium bone of the wrist and the metacarpal bone of the thumb. This is one of the joints where most humans develop osteoarthritis with age. Osteoarthritis is age-related loss of the smooth surface of the bone where it moves against another bone (cartilage of the joint). In reaction to the loss of cartilage, the bones thicken at the joint surface, resulting in subchondral sclerosis. Also, bony outgrowths, called osteophytes (also known as “bone spurs”), are formed at the joint margins.
Ankle fusion, or ankle arthrodesis, is surgery of the ankle to fuse the bones to treat arthritis and for other purposes. There are different types of ankle fusion surgery. The surgery involves the use of screws, plates, medical nails, and other hardware to achieve bone union. Ankle fusion is considered to be the gold standard for treatment of end-stage ankle arthritis. It trades joint mobility for relief from pain. Complications may include infection, non-union, and, rarely, amputation.
Posterior tibial tendon dysfunction is the dysfunction of the posterior tibial tendon. It is a progressive disease that has 4 stages and is the most common cause of adult flatfoot.
