Precise application of Traditional Chinese Medicine in minimally-invasive techniques / 中国骨伤

The miminally-invasive techniques of traditional Chinese medicine(TCM) uses different types of acupuncture needles to treat diseased locations with special techniques. These techniques include different methods of insertion and closed incision (press cutting, sliding cutting, scrape cutting, etc.). This needling technique is based on the traditional Chinese medicine theories of (cutaneous), (sinew), (meridian), (five body structure components) and (organ system). Commonly used needles include: needle , needle with edge, needle, needle, needle, needle, needle, needle and so on. The principle of this minimally-invasive technique of TCM is to achieve the greatest healing benefit with the least amount of anatomical and physiological intervention. This will result in the highest standard of health care with the lowest rehabilitative need and burden of care. In the past 20 years, through the collaborative research of several hundred hospitals across China, we systemically reviewed the best minimally invasive technique of TCM and the first line treatments for selective conditions. In 2013, the Department of Medical Affairs of the State Administration of Traditional Chinese Medicine created "Traditional Chinese Medicine Technical Manual"(General Version) and released it nationwide, its contents include: (1)Minimally invasive scar tissue release. ¹Suitable for Bi and pain syndromes of neck, shoulder, waist, buttocks and extremities. ²Degeneration causes local hypertrophy and inflammation, creating local tissue adhesion. ³There are two kind incision methods-press cutting and slide cutting. (2)Minimally invasive fascial tension release. ¹Suitable for localized fascial tension caused by trauma, overuse, or wind-cold-dampness, leading to compensatory hyperplasia. ²Long term high-stress stimulation to local fascia creates compensatory hyperplasia, Ashi points, and tissue texture changes (cords, nodules, masses). ³According to the different structural features of the needles, there are two incision methods: penetrating from the outside to the inside and pulling from inside to outside. (3)Minimally invasive decompression technique. ¹Suitable for internal pressure changes within organ cavities caused by trauma, degeneration, inflammation, such as compartment syndrome, bone marrow edema, increased intraluminal pressure in the bone marrow. ²According to the different tissues, it is categorized into soft tissue decompression, and bone decompression. (4)Minimally invasive orthopedic surgery. Applicable to some postural, developmental deformity correction, mainly through the dynamic balance method and/or static balance method. (5)Minimally invasive dissection. Suitable for fractures, tendons injury caused by deep soft tissue adhesion. (6)Minimally invasive separation. ¹Suitable for cutaneous, sinew regions, superficial adhesions due to lesions, and local post-operative incision adhesions. ²According to the structure of the needle tip, the methods are divided into sharp separation and blunt dissection. (7)Minimally invasive sustained pressure technique. ¹Suitable for neuromuscular dysfunction which causes (spasm) syndrome and (atrophy) syndrome. ²The needle is applied with sustained pressure, without penetrating select tissue surface. This includes: nerve root sustained pressure technique; peripheral nerve sustained pressure technique; muscle sustained pressure technique; fascial contact procedure; cutaneous sustained pressure technique.(8)Minimally invasive insertion technique. ¹Suitable for systemic regulation to treat disease. ²Different organs are connected to different layers of tissue. Therefore, to treat specific conditions, specific tissues must be targeted. ³For example, back Shu points are used to treat vertigo from cervical spine issues, and spinal degeneration associated digestion issue. ⁴The internal organs can be regulated by the pathways that runs along the different layers of tissue. The types of stimulation include: meridian acupoint stimulation; cutaneous stimulation; fascia stimulation; mucle stimulation; periosteum stimulation. The clinical application of these techniques has enriched the drug-free therapies of traditional Chinese medicine and achieved excellent outcomes, but at the same time it also raises an important question. How can we apply these minimally invasive techniques to clinical practice so it can be safe and effective? In addition, how can practitioners, individually and further develop their understanding of this minimally invasive technique progressive manner? We make the following recommendations. (1)Clear diagnosis and precise application. Any approach has specific indications and choosing the correct technique comes from a comprehensive understanding of its advantages and disadvantages. Moreover, the accurate application of the technique depends the expertise of the practitioner. Through systematic review and clinical observation, we formulated the First Line Treatment, the Second Line Treatment, and the Third Line Treatment for specific conditions. Using the information gathered from research, practitioners can decide on which point is appropriate to use based on the stage of disease progression. For example, common conditions like the nerve ending tension pain(i.e. cutaneous nerve entrapment syndrome) is caused by stress concentration. There are two types of treatment for this condition: ¹Change in the response to stress state (i.e.non-invasive approach such as manual therapy and physiotherapy). ²Change in state of surrounding environment (i.e. invasive approach such as Needle). Before tissue texture changes to pain point, cord, nodules, the former approach is effective. Once tissue texture changes, the latter approach is First Line Treatment. (2)Systematic training and disease progression training. The minimally invasive techniques of traditional Chinese medicine can treat many kinds of disease. To ensure its safety, organization, progressive development, practitioners are trained systematically and manage their treatment approach through disease hierarchy. Moreover, this technique should be conducted according to its technical difficulty, operating conditions, and expertise of the practitioner. The application of minimally invasive techniques of traditional Chinese medicine does not depend on the hospitals' administration system or the regulatory college of medical professionals. The minimally invasive techniques of TCM should be taught from easy to difficult, simple to complicated, and requires gradual progression by the practitioners. Eventually, the minimally invasive techniques of TCM's diagnostic and treatment protocol can be created. These protocols are currently available for reference: ¹Forming diagnosis and differential diagnosis for the conditions below requires expert diagnostic and application skills: cerebral palsy; cervical vertigo; cervical headache; cervical precordial pain; other spine-related diseases. ²The requirements for the diagnosis and differential diagnosis of such techniques are relatively high, and special training is required for the practitioner who performs this technique. The conditions below uses minimally invasive orthopedic surgery and dissection: scar contracture deformity; congenital developmental malformations; cervical -syndrome; shoulder pain syndrome; knee -syndrome; low back pain; cervical spondylosis; lumbar disc herniation; avascular necrosis of the femoral head; ankylosing spondylitis. ³There are no special requirements for the diagnosis and differential diagnosis of such techniques, and special training is required for the practitioner who performs this technique. The technical content is mainly decompression and scar tissue release. a)Muscle strain diseases: levator scapulae, splenius capitis, splenius cervicis, supraspinatus, infraspinatus, teres minor, teres major, serratus posterior superior, serratus posterior inferior, piriformis, gluteus maximus, gluteus medius, and gluteus minimus, erector spinae. b)Joint degenerative disorders: frozen shoulder, tennis elbow, tenosynovitis, knee osteoarthritis, and plantar fascitis. c) pain syndrome (cutaneous nerve entrapment syndrome): occipital great nerve entrapment syndrome, occipital small nerve entrapment syndrome, great auricular nerve entrapment syndrome, suprascapular nerve entrapment syndrome, transverse cutaneous nerve of neck entrapment syndrome. (3)People-centred practice. The most attractive feature of the minimally invasive techniques of TCM is that they do not rely on expensive medical equipment and operating conditions. The key to applying this technique is the practitioners' technique, skill, and expertise. The necessary conditions required to successfully apply this technique is ¹practitioner understands disease progression and diagnosis; ²practitioners' skill in applying technique. We require patient-centered approach, which uses evidence based approach as the focus. We aim to seek the truth from facts, to understand the comprehensive picture, to include pertinent details, to be observant, to be goal oriented, from one to another, from outside to inside, from top to the bottom, compare right from left, through active movement and passive movements and weight-bearing movements, and assisted passive movements to determine instantaneous centre to diagnose stress concentration points. The operating technique is based on the response of patient's tissues to this technique. We must pay attention to diagnosis through palpation: layers, structure, texture, deformity, dislocation, movement characteristic, rhythmic changes. To achieve : position, quantify, quantity, timing, and pattern. Accurate grasp of timeliness and dose efficiency. Can distinguish between local or systemic effects of treatment. Through comprehensive judgment of hands feeling, acupuncture needle feeling, and inspiration, to achieve the precious treatment requirements as indicated by the : "Puncture the bone without damaging tendons, and puncture tendons without damaging muscles, puncture the muscle without damaging pulse, puncture pulse without damaging skin, puncture skin without damaging muscle. Puncture muscle without damage tendons, puncture tendons without damaging bone... Puncture bone without damaging tendons and it means the needle passes through the tendons and arrives at the bone and work on the bone. Puncture tendons without damaging muscles, and it means the needle passes through the muscles and arrives close to the tendon. Puncture the muscle without damaging pulse and it means the needle passes the pulse and does not touch the muscle. Puncture pulse without damaging skin and it means, the needle passes through the skin without penetrating pulse. Puncture skin without damaging muscle and it means, the disease is in the skin and the needles insert into skin but does not damage muscle. Puncture muscle without damage tendons, and it means, the needle passes through the muscle and arrive on the tendon. Puncture tendons without damaging bone."

Regeneration and functional recovery of rabbit knee joint after osteotomy under control of external artificial joint / 医用生物力学

Objective To discuss the possibility for regeneration of knee joint with normal function under bionics biomechanical environment. Methods Seven normal rabbits with two metal frames respectively mounted on their femur and tibia of single (right) side leg by two threading pins of 1.5 mm diameter were used. Then the external artificial joints, containing two four-bar-linkage inside and outside of the knee to simulate motion trajectory of the joint in sagital plane were connected with the two preset fixed frames before osteotomy. The arthro-cartilage of the knee joint, crucial ligaments, semi-lunar fibro-cartilages, and partial under-cartilage-osseous intra articular capsule were cut off during osteotomy, with the patella, sesamoid bones remained intact. Insertion sites of muscle tendons were not invaded as far as possible, and capsules with ligaments outside were kept complete when the incision wound was closed by suture. The rabbits could move freely after osteotomy. The range of motion (ROM) of the knees in sagital plane and bony gap between the femur and tibia were measured by X-Ray films during the fracture healing after osteotomy. Results External artificial knee joints were successfully installed on right legs of 6 rabbits among the seven. The rabbits moved freely after osteotomy under the control of minimal invasive external artificial joint in bionics trajectory. The average angles between femoral shaft and tibial shaft at the 1st week after osteotomy were from (144.7±15.62)° in extremely flexed position to (44.2±25.77)° in extremely extended position, with ROM of (100.5±29.03)°. At the 12th week, the average angles were from (139.4 ± 12.92)° in extremely flexed position to (40.4±22.04)° in extremely extended position, with ROM of (99.0±23.39)°. No significant differences were displayed in flexed/extended position and ROM between the 1st and 12th week, with the bony gaps of the knees still existed but decreased significantly from (4.03±1.84) mm at the 1st week to (2.32±1.05) mm at the 12th week. In contrast, bony gaps of the opposite knees were not changed significantly, which were (1.27±0.22) mm on average. At the end of 16th week after osteotomy, the external artificial joints were removed. Newly born cartilage, with white color and smooth surface, were covered at lower end of the femur and upper end of the tibia. Typical trochlear surface appeared at the front side of regenerated cartilage corresponding to the posterior surface of the patella. And the regenerated fibro-bundle linkage similar with ligament, which started from bony structure of regenerated lower end of the femur and inserted into regenerated upper end of the tibia, was observed in each rabbit. At the 25th week, the average angles between femoral shaft and tibial shaft were from (148.3 ± 4.75)° in extremely flexed position to (48.30±17.57)° in extremely extended position, with ROM of (100.0±20.80)°. In the opposite (left) leg, the average angles between femoral shaft and tibial shaft were from (148.3±7.5)° in extremely flexed position to (21.6±9.09)° in extremely extended position, with ROM of (126.7±6.88)°, and the average bony gap of the knees after osteotomy was (1.4±0.59) mm, while that of the opposite (left) knees was (0.92±0.35) mm. Conclusions The external artificial joint with bionics trajectory could reserve the space for regeneration of rabbit knee joint by providing motion modeling environment, and proved the stress adaption during fracture healing. The present results indicated that regeneration of the knee joint after intra-capsular osteotomy in bionics biomechanical environment was possible.

Effects of tension relaxation by small needle knife on muscle tension and nerve endings after compression of gracilis muscle in rats / 中国骨伤

<p><b>OBJECTIVE</b>To determine the effect of tension relaxation by small needle knife on the muscle tension and morphology changes of nerve terminals when sustained pressure was applied to muscular tissue.</p><p><b>METHODS</b>Rat gracilis muscles were exposed to pressure in vivo at 70 kPa for 2 hours. Sixty rats were divided into three groups: normal, control and experiment group respectively. In all rats except the six normal ones, the lower legs were considered as the control group, and the right left as experiment group. At day 1, 2 and 3, 9 rats from the two groups were randomly selected and sacrificed in order to determine the muscle tension change. At the same time, muscle histology and morphology changes of nerve terminals were observed.</p><p><b>RESULTS</b>Abnormal tension increased in muscles under compression of 70 kPa. At the 1st and 2nd days, there were no significant differences between the two groups. Compared with control group, the tension was lower in experiment group, and there was statistically significant difference (P < 0.01) between the two groups. Exposure of striated muscle tissue to intensive and prolonged compression may pathologically alter its microstructure. Histological evaluation showed that this stiffening accompanied extensive necrotic damage. The changes could not be found in the nerve terminals.</p><p><b>CONCLUSION</b>Deep muscle tissue that undergoes prolonged compression may significantly increase its stiffness during acute injury. Tension relaxation applied by small needle knife can effectively reduce the mechanical load which is harmful to the whole tissue.</p>

Using radiographs to analyze equivalent weakest transverse interface of fracture healing / 医用生物力学

Objective An effective but simple method for quantifying the fracture healing progress was provided to obtain more information on fracture healing mechanics from plain X-ray film. Method Twelve rabbits were used for experimentally osteotomy at the middle tibiae, each of which was fixed by the sliding fixator with four pins of 1.5 mm diameter, with mini transducer of displacement measuring the sliding micro movement between the fractured bone fragments, denoted as ΔL. The bending rigidity, denoted as K=P/ ΔL, of the rabbits’ tibia (with sliding fixator together) were recorded by computer data assembling system once a week, where P was the load on the fracture site from anterior of the tibia by manual operation of a loading transducer. The anterior posterior and lateral radiographs were also taken every week by digitally upgraded X-ray radioscope. The effective weakest transverse curved interfaces were found, and the equivalent bending moments of inertia were calculated from the radiographs automatically, by gray scan along the longitudinal axis of the tibia upon the image programs edited in Delphi programming environment. And they were used for quantitative description of the rigidity of the healing bone. Results The sliding fixators were removed in 29~41 days after the osteotomy. Ratios of the minimum to the maximum of equivalent bending moments of inertia for each fracture bone were calculated. And they were found to increase via the healing time. The means of the ratios of all twelve rabbits calculated from lateral radiographs were (0.31±0.17) for the first week, (0.34±0.13) for the second week，(0.43±0.20) for the third week, and (0.56±0.23) for the fourth week after the osteotomy, respectively. From anterior posterior radiographs, the means of the ratios were (0.40±0.19), (0.47±0.16)， (0.56±0.20), and (0.66±0.11), respectively. These ratios were significantly correlated with the bending rigidity K of the fracture tibia of the rabbits. The means of K value was （3.976±4.986）N•μm-1 before the operation，and （0.679±1.026）N•μm-1 for the first week，（2.115±3.233）N•μm-1 for the second week，（3.459±4.723）N•μm-1 for the third week and （4.788±4.831）N•μm-1 for the fourth week after the operation, respectively. Conclusions The growth of external callus has its own rules. It can be distinguished from plain radiographs easily, and it grows from either side of the fracture site and meets together gradually, filling up the gap at the fracture site at last. The methods described in this paper could reflect the feeling when reading the radiographs.

Effects of small needle knife on the substance P in the dorsal root ganglion and spinal cord of rats / 中国骨伤

<p><b>OBJECTIVE</b>To study the mechanism of synthesis of substance P (SP) in the dorsal root ganglion (DRG) and the release of it in the dorsal horn of the spinal cord of rats after compression of skeletal muscle, and to observe the influence of small needle knife.</p><p><b>METHODS</b>Sustained pressure of 70 kPa was applied to rats, muscular tissues for 2 hours. The rats were divided into three groups: normal, control and experiment group respectively. In all rats except the six normal ones, the lower legs were compressed once one day. The left leg was considered as the control group, the right left was experiment group, which were divided into the 1st day, the 2nd day and the 3rd day within the two groups. Experiment group was treated with small needle knife after the muscular tissue was compressed. After completing the stimulation, the DRG related to the muscle and part of spinal cord were removed for the qualification of SP-like immunoreactivity using immunohistochemistry. The dark brown stains on the DRG and on the REXed laminae I and II in the dorsal horn of the spinal cord were counted by Image-Pro Plus software.</p><p><b>RESULTS</b>SP-like immunoreactivity in the side treated by the small needle knife was enhanced comparing with the counterpart in DRG in normal group (P < 0.01). The integrated optical density of SP like immunoreactivity of the DRG in the experiment group were significantly reduced compared with the control group (P < 0.05). However, the release of SP from spinal cord in experiment group was lower than that in the control group at the 1st day and the 3rd day (P < 0.01), with the opposite result of the 2nd day.</p><p><b>CONCLUSION</b>Based on the fact that SP is a nociceptive neurotransmitter, the present study suggests that tension relaxation by small needle knife reduces expression of SP in the DRG, and shows no effects on the release of SP from the spinal cord in short-term (3 days).</p>

Vertebra morphology measurement in adolescent idiopathic scoliosis population / 中华外科杂志

<p><b>OBJECTIVE</b>To measurement the vertebra morphology using multi-planar reformations method of multi-slice spiral CT (MSCT) in AIS girls, and To compare with age and gender-matched controls in order to affirm the morphology results of abnormal development of the anterior and posterior elements in AIS.</p><p><b>METHODS</b>Thoracic and lumbar spine multi-slice spiral CT was undertaken on 52 girls with AIS between the age of 10 and 18 years from June 2004 to May 2008 in Peking Union Medical College Hospital and Beijing Shijitan Hospital, and 54 age and gender-matched non-IS controls. Multiple measurements (including the anterior column and posterior column) of each thoracic and lumbar vertebra were obtained using the 3D-MPR technique. The patients and control were divided into 10-14 years old group and 15-18 years old group. The corresponding vertebral anterior height, vertebral posterior height, transverse distance, vertebra central width, vertebra anterior-posterior distance, area of pedicle, pedicle height, pedicle width, and upper-lower facet distance were compared.</p><p><b>RESULTS</b>Compared with the controls, the 10-14 years old group girls' spine had longer anterior column height, relative shorter posterior column (there are difference from thoracic 2-11 and lumbar 1-3, P < 0.05), relative longer anterior-posterior vertebral distance, vertebral wedging changes in vertebral, distinct vertebral and pedicle asymmetry on the concave and convex side, and upper-lower facet distance asymmetry on the concave and convex side. The difference between the anterior and the posterior column ratio was significantly different from that in the controls (P < 0.01). But there hadn't the same difference in 15 - 18 years old group.</p><p><b>CONCLUSIONS</b>There are differences in coronal plane vertebra wedging changes in AIS patient. There are high vertebra height, relative shorter posterior column, relative longer anterior-posterior vertebral distance, and relative slender vertebra in 10 - 14 years old AIS patients. This may lead to the initial and progression of scoliosis.</p>
