Manipulation under anesthesia (MUA) or fibrosis release procedures [1] is a noninvasive procedure to treat chronic pain which has been unmanageable by other methods. MUA is designed not only to relieve pain, but also to break up excessive scar tissue. Scar tissue frequently builds up after orthopedic surgery, impeding movement of soft tissue and joints, so MUA is valuable in re-establishing optimal range of motion. [2] The patient normally goes through a series of examinations, including imaging tests and laboratory work, before undergoing MUA. These tests are necessary to precisely identify the targeted area and to ensure the patient's able to benefit from the procedure. MUA may be performed by a number of different types of medical professionals, but only those who have studied MUA and received certification in the technique. [3]
This is a non-invasive procedure that seems to help regain mobility accomplished by a combination of controlled joint mobilization/manipulation and myofascial release techniques, while the patient is under sedation. [4] MUA is used by osteopathic/orthopedic physicians, chiropractors and specially trained (MUA certified) physicians. It aims to break up adhesions (scar tissue) on and around spinal joints as the cervical, thoracic, lumbar, sacral, and pelvic regions, or extremity joints as the knee, shoulder and hip, to which a restricted range of motion can be painful and limit function. Failed attempts at other standard conservative treatment methods (i.e., manipulation, physical therapy, medication), over a sufficient time-frame, is one of the principal patient qualifiers. [5] [6] [7] [8]
Historically, the medical literature identifies sodium pentothal as the earliest of the anesthetizing agents used with the MUA procedure. [6] [9] [10] [11] [12] [13] That was followed by a period during which propofol was used to induce a “twilight state” [14] (aka, IV sedation or conscious sedation [15] ). The latter became the doctor-preferred means of rendering the service, as it offered preservation of patient responsiveness during the delivery of treatment. [16] With today's MUA procedure, deep conscious sedation is accomplished with agents such as propofol, [17] [18] [19] through monitored anesthesia care (MAC).
As a less common mode of MUA treatment, select injectable medications can be administered directly into affected synovial joints, [20] spinal facet joints, [21] or into the surrounding epidural space. [22] [23] [24] [25]
Medication-assisted manipulation (MAM) has been used since the 1930s, and MUA was practiced by osteopathic physicians and orthopedic surgeons in the 1940s and 1950s. It was largely abandoned due to complications from general anesthesia and due to the type of nonspecific manipulation procedures used. It was modified and revived in the 1990s, primarily by chiropractors, and also by osteopathic physicians; this was likely due to safer anesthesia used for conscious sedation, along with increased interest in spinal manipulation (SM). [26]
In the MUA literature, spinal manipulation under anesthesia has been described as a controversial procedure. [27] [28] It has had a history susceptible to enthusiastic claims of success and indiscriminate use. [29] With continued misperceptions about the findings and significance of primary research, [30] similar issues remain today.
Author/s cited | Commonly reported outcomes claims | Actual outcomes data and relevant study methods, as reported by publication |
---|---|---|
Bradford and Siehl | 71% of 723 MUA patients had good results (return to normal activity relatively symptom free) and 25.3% had fair results (return to normal activity with slight residuals) | Overall, for 723 cases (666 different patients), 60% had good results, 30% had fair results, and 10% had poor results. Most patients received a single procedure dose. As for the 185 patients with herniated disc, 26.4% had good results and 44.3% had fair results, with the author reporting, “improvement was quite temporary in a number of cases, since 51% required subsequent operation.” [31] |
Chrisman, et al. | 51% of patients reported good to excellent results three years post MUA | 51% of 39 patients had good or excellent results after rotatory manipulation of the spine under anesthesia. Of patients with positive myelograms, 37% (10 of 27) had good to excellent results three years or more after manipulation. All patients received a single procedure dose. [32] |
Krumhansl and Nowacek | Of 171 patients receiving MUA, 25% had no pain, 50% were much improved (with pain markedly decreased), and 20% were better and could tolerate their pain (but it interfered with work and recreation) | Of 171 patients, most of whom received a single procedure dose, approximately 25% were “cured” (having no pain of the type experienced prior to MUA), 50% were “much improved” (with markedly diminished pain and function restored but with intermittent nuisance type pain with weather changes or strenuous activity) and 20% were “better, but” (having a tolerable pain level but remained dysfunctional for work and recreational activities). [33] |
Kuo and Loh | 83% of 517 patients treated with MUA responded well | Of 517 patients receiving manipulation, 76.8% had satisfactory results. However, the number of patients anesthetized during manipulation is not reported (if any). In general terms, the authors state, “Prior to manipulation, general anesthesia with intravenous thiopental sodium may be given to suppress pain and muscle spasm.” Seventy-three patients (14%) had a condition recurrence or relapse, ranging from 2 months to 12 years after the first series of manipulations. Unresponsive patients (9%, overall) underwent surgical exploration and received a second series of manipulations after revision of the treatment protocol such that 434 of 517 patients (83.9%) are reported as having responded well to manipulation. [34] |
Mensor | 83% of 600 patients with EMG-verified radiculopathies reported significant improvement following MUA | For over 600 patients treated, a cursory evaluation led the author to “believe that the percentage of success or failure has not changed materially” from the original report. [35] The original report cited excellent to good results in 64% of private patients and 45% of industrial accident patients with disabilities. [36] Overall, 83% of patients received a single procedure dose, with the author reporting, “repeated manipulation is not justified” for satisfactory results. Within neither paper is EMG testing mentioned as part of the patient's objective findings or as a qualifier for treatment. |
Ongley, et al. | Patients that had back pain for a minimum of 10 years reported an 87% recovery rate after MUA | Eighty-one patients had an average pain duration of 10 years. Patients in the experimental group were placed in a diazepam-induced amnesic state, and received manipulation after administration of local anesthetic to six different ligaments of the lumbar, lumbopelvic, and sacroiliac regions. At six months, of the 40 patients in the experimental group who received a single procedure dose, 87.5% had greater than 50% improvement in disability scores and 37.5% had recovered completely (“free from disability”). [37] |
Since the 1930s, spinal manipulation under anesthesia has been reported in the published medical literature. Within the existing base of studies is some reports of positive results. However, it appears that as part of the evolution of the procedure, the medical literature reveals many variations in [A] the type of sedatives/medications used, [B] manipulation technique, [C] the number of MUA sessions employed, [D] the span of time between procedure doses (if administered in series), and [E] the types and breadth of application of post-MUA adjunctive and/or rehabilitative measures. [38]
There has been and remains a strong theoretical basis for spinal MUA. However, considering the aforementioned differences in existing published studies, field practitioners have not had an objective and uniform means by which to establish evidence-based treatment protocols. [38] Also, because the preponderance of studies is of lower level evidence [39] [40] the issue of long-term effectiveness of MUA in the management of specific spinal conditions has yet to be investigated. Another area for which basic experimental research is lacking to support the efficacy of MUA treatment of the low back, [17] and other spinal regions, relates to the two presiding theories that [A] flexibility of the spine may be increased when adhesions are reduced, and [B] MUA is more effective at treating adhesions than office-based manual therapy methods. Perhaps of greater significance, the circumstances by which or how often spinal adhesions (scar tissue) may form in the general population, in the presence or absence of prior surgery or vertebral fracture, have not been addressed in the medical literature. [41]
A 2005 consensus statement from the American Academy of Osteopathy indicates that research and publication is limited for the use and effectiveness of MUA. [8] More recently, it has been reported that there are gaps in the medical literature for spinal MUA in the areas of patient selection and treatment protocols. [5] On account of that, a Delphi process was undertaken to develop evidence-informed and consensus-based guidelines for the chiropractic profession. [42] The outcome of that process offers direction to MUA practitioners and facilities, although not intended for individual patients. [5]
Notably, the criteria recommended by members of the chiropractic profession [5] are distinctly different from the criteria established by the American Academy of Osteopathy. [8] Moreover, the Delphi method is a consensus process which represents consenting opinion from an impaneled group of experts. But with expert opinion serving as the lowest level of evidence (Level V) in the medical evidence hierarchy, [43] the MUA-related Delphi process publication of 2014 does not enhance the state of the evidence for spinal MUA. Therefore, the largely anecdotal basis for procedural effectiveness, [38] and continued reliance upon the spinal MUA protocols historically used, [44] are what principally influence the practice of MUA today.
In comparison to other available treatment options for chronic spine pain patients, it is the benchmark of the randomized controlled trial that would most accurately define patient candidacy, optimal procedure dosing, and long-term effectiveness for MUA. Previous MUA investigators have mentioned the use of inconsistent protocols [45] and have called for large-scale MUA studies (randomized trials) for chronic low back pain. [46] [47] To date, no such studies have been undertaken. [30]
Due to the lack of high-level research evidence for the long-term clinical efficacy of spinal MUA, several traditional criteria for patient selection are without support or remain unproven. The most recent analysis of the published medical evidence for MUA shows that disc herniation/protrusion qualifies as at least a relative contraindication, with risk for injury and no proven long-term benefit. [41] Also, in the presence of a positive lumbar EMG study (nerve root compression) with lumbar disc herniation, Level II evidence suggests that patients will eventually need surgical correction. [48] For chronic neck and low back pain patients who also have significant anxiety/stress, Level II evidence suggests that MUA will not be of therapeutic benefit. [49] Accordingly, most insurance carriers in the United States maintain medical policy which deems the spinal MUA unproven or experimental/investigational. [50] [39] [40]
Patients that may qualify for MUA to an extremity joint include those with stiff post-operative knee joints that have undergone total knee replacement (total knee arthroplasty- TKA). [51] [52] [53] [54] Range of motion data taken at discharge following TKA have been suggested as an indicator for MUA, when falling short of the “optimal zone” of ≥70˚ flexion combined with an extension deficit of ≤10˚. [55] It appears that the ideal period for applying manipulation to knee stiffness after TKA is at less than 20 weeks from primary surgery, with no added benefit reported from re-manipulations. [56] Similarly, another recent study also found that MUA is useful for decreased range of motion but the success rate of repeated MUA was less than that of the primary dose. [57]
Outside of the above clinical scenario and related research, the supportive evidence for MUA to other extremity joints is weak, inconclusive or non-existent. The shoulder, when failing to achieve flexibility following standard treatment, is one of the extremity regions for which the frozen shoulder condition has traditionally been cited as an indication for MUA. There are some supportive studies in this area, including one showing that patients fare better with intervention at 6 and 9 months after condition onset (having significantly better abduction and external rotation, with less pain at rest and at night). [58] However, for those studies which represent the highest level of research evidence, the results of two recent systematic reviews for frozen shoulder raise question as to treatment superiority when compared to other forms of treatment. Namely, in the 2012 systematic review, Maund, et al. found a single adequate study, but no evidence there of better outcome with MUA versus home exercise. [59] In the 2015 systematic review, Uppal, et al. determined MUA to be equivocal at best, when compared to hydrodilation and steroid injection. [60]
The provision of MUA to an extremity joint is reserved for primary conditions thereof, such as a frozen articulation. The practice of applying MUA to an extremity joint that conjoins the spine (i.e., shoulder and/or hip), as a routine component or an extension of a spinal MUA procedure, is not supported by clinical investigation. [38]
Tens of thousands of uneventful spinal and extremity MUA procedures have been performed in the United States over the past several decades. As such, in all likelihood, the risks with the procedure are relatively low or minimized with current techniques and when patients are properly selected and evaluated by the anaesthesiologist, the medical physician who is providing medical clearance, and the MUA manual therapy practitioner (DC, DO, MD). However, as with any procedure, there are inherent risks with MUA. The chiropractic literature seems to best address concern for complications, poor outcomes, or adverse events with spinal MUA.; [45] [41] however, better event reporting is needed in developing more definitive risk criteria. In part, these include severe sacroiliac pain with transient “pain paralysis” (of one or both legs), [61] transient respiratory distress, [61] a significant adverse cardiovascular event, [62] spinal fracture with hemothorax, [63] lower extremity fracture, [64] [65] glenoid fracture, [66] shoulder dislocation, [67] and pseudoaneurysm. [68]
Chiropractic is a form of alternative medicine concerned with the diagnosis, treatment and prevention of mechanical disorders of the musculoskeletal system, especially of the spine. It is based on several pseudoscientific ideas.
Back pain is pain felt in the back. It may be classified as neck pain (cervical), middle back pain (thoracic), lower back pain (lumbar) or coccydynia based on the segment affected. The lumbar area is the most common area affected. An episode of back pain may be acute, subacute or chronic depending on the duration. The pain may be characterized as a dull ache, shooting or piercing pain or a burning sensation. Discomfort can radiate to the arms and hands as well as the legs or feet, and may include numbness or weakness in the legs and arms.
Orthopedic surgery or orthopedics is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders.
Low back pain or lumbago is a common disorder involving the muscles, nerves, and bones of the back, in between the lower edge of the ribs and the lower fold of the buttocks. Pain can vary from a dull constant ache to a sudden sharp feeling. Low back pain may be classified by duration as acute, sub-chronic, or chronic. The condition may be further classified by the underlying cause as either mechanical, non-mechanical, or referred pain. The symptoms of low back pain usually improve within a few weeks from the time they start, with 40–90% of people recovered by six weeks.
Degenerative disc disease (DDD) is a medical condition typically brought on by the aging process in which there are anatomic changes and possibly a loss of function of one or more intervertebral discs of the spine. DDD can take place with or without symptoms, but is typically identified once symptoms arise. The root cause is thought to be loss of soluble proteins within the fluid contained in the disc with resultant reduction of the oncotic pressure, which in turn causes loss of fluid volume. Normal downward forces cause the affected disc to lose height, and the distance between vertebrae is reduced. The anulus fibrosus, the tough outer layers of a disc, also weakens. This loss of height causes laxity of the longitudinal ligaments, which may allow anterior, posterior, or lateral shifting of the vertebral bodies, causing facet joint malalignment and arthritis; scoliosis; cervical hyperlordosis; thoracic hyperkyphosis; lumbar hyperlordosis; narrowing of the space available for the spinal tract within the vertebra ; or narrowing of the space through which a spinal nerve exits with resultant inflammation and impingement of a spinal nerve, causing a radiculopathy.
Spinal adjustment and chiropractic adjustment are terms used by chiropractors to describe their approaches to spinal manipulation, as well as some osteopaths, who use the term adjustment. Despite anecdotal success, there is no scientific evidence that spinal adjustment is effective against disease.
Spinal manipulation is an intervention performed on synovial joints of the spine, including the z-joints, the atlanto-occipital, atlanto-axial, lumbosacral, sacroiliac, costotransverse and costovertebral joints. It is typically applied with therapeutic intent, most commonly for the treatment of low back pain.
Traction is a set of mechanisms for straightening broken bones or relieving pressure on the spine and skeletal system. There are two types of traction: skin traction and skeletal traction. They are used in orthopedic medicine.
Failed Back Syndrome is a condition characterized by chronic pain following back surgeries. The term "post-laminectomy syndrome" is sometimes used by doctors to indicate the same condition as failed back syndrome. 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 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.
A disc herniation or spinal disc herniation is an injury to the intervertebral disc between two vertebrae, usually caused by excessive strain or trauma to the spine. It may result in back pain, pain or sensation in different parts of the body, and physical disability. The most conclusive diagnostic tool for disc herniation is MRI, and treatments may range from painkillers to surgery. Protection from disc herniation is best provided by core strength and an awareness of body mechanics including good posture.
Joint manipulation is a type of passive movement of a skeletal joint. It is usually aimed at one or more 'target' synovial joints with the aim of achieving a therapeutic effect.
Radiculopathy, also commonly referred to as pinched nerve, refers to a set of conditions in which one or more nerves are affected and do not work properly. Radiculopathy can result in pain, weakness, altered sensation (paresthesia) or difficulty controlling specific muscles. Pinched nerves arise when surrounding bone or tissue, such as cartilage, muscles or tendons, put pressure on the nerve and disrupt its function.
Arthrofibrosis has been described in most joints like knee, hip, ankle, foot joints, shoulder, elbow, wrist, hand joints as well as spinal vertebrae. It can occur after injury or surgery or may arise without an obvious cause. There is excessive scar tissue formation within the joint and/or surrounding soft tissues leading to painful restriction of joint motion that persists despite physical therapy and rehabilitation. The scar tissue may be located inside the knee joint or may involve the soft tissue structures around the knee joint, or both locations.
An artificial facet replacement is a joint prosthesis intended to replace the natural facets and other posterior elements of the spine, restoring normal motion while providing stabilization of spinal segments. It is typically used as an adjunct to laminectomy, laminotomy, neural decompression, and facetectomy, in lieu of standard lumbar fusion. The prosthesis is indicated for back and leg pain caused by central or lateral spinal stenosis, degenerative disease of the facets with instability, and grade 1 degenerative spondylolisthesis with objective evidence of neurological impairment.
Neurogenic claudication (NC), also known as pseudoclaudication, is the most common symptom of lumbar spinal stenosis (LSS) and describes intermittent leg pain from impingement of the nerves emanating from the spinal cord. Neurogenic means that the problem originates within the nervous system. Claudication, from Latin claudicare 'to limp', refers to painful cramping or weakness in the legs. NC should therefore be distinguished from vascular claudication, which stems from a circulatory problem rather than a neural one.
Chiropractors use their version of spinal manipulation as their primary treatment method, with non-chiropractic use of spinal manipulation gaining more study and attention in mainstream medicine in the 1980s. There is no evidence that chiropractic spinal adjustments are effective for any medical condition, with the possible exception of treatment for lower back pain. The safety of manipulation, particularly on the cervical spine has been debated. Adverse results, including strokes and deaths, are rare.
Osteomyology is a multi-disciplined form of alternative medicine found almost exclusively in the United Kingdom and is loosely based on aggregated ideas from other manipulation therapies, principally chiropractic and osteopathy. It is a results-based physical therapy tailored specifically to the needs of the individual patient. Osteomyologists have been trained in osteopathy and chiropractic, but do not require to be regulated by the General Osteopathic Council (GOsC) or the General Chiropractic Council (GCC).
Spinal decompression is the relief of pressure on the spinal cord or on one or more compressed nerve roots passing through or exiting the spinal column. Decompression of the spinal neural elements is a key component in treating spinal radiculopathy, myelopathy and claudication.
The McKenzie method is a technique primarily used in physical therapy. It was developed in the late 1950s by New Zealand physiotherapist Robin McKenzie. In 1981 he launched the concept which he called "Mechanical Diagnosis and Therapy (MDT)" – a system encompassing assessment, diagnosis and treatment for the spine and extremities. MDT categorises patients' complaints not on an anatomical basis, but subgroups them by the clinical presentation of patients.
Primary spine practitioners are health care professionals who are specially trained to provide primary care for patients with spinal disease.
