[Short-term efficacy of digitally-assisted traditional Chinese medicine manual reduction combined with 3D printed splint in the treatment of AO type-A distal radius fractures].

Objective To explore the short-term efficacy of digitally-assisted traditional Chinese medicine manual reduction combined with 3D printed splint in the treatment of AO type-A distal radius fractures, and explore the quantification of traditional Chinese medicine manual reduction and personalized improvement of splinting. Methods The clinical data of 50 patients with AO type-A distal radius fractures, who received treatment at the outpatient department of Cangzhou Integrated Traditional Chinese and Western Medicine Hospital in Hebei Province, were retrospective analyzed. The patient cohort included 22 females and 28 males, with ages ranging from 25 to 75 years old. Among them, 27 cases presented with distal radius fractures on the left side, and 24 cases on the right side. The patients were categorized into two groups: treatment group (n=25) and control group(n=25). There were 13 males and 12 females in the treatment group, with an average age of (56.2±5.5) years old. Treatment approach for this group involved several steps. Initially, Mimics Research software was used to conduct comprehensive analysis of complete CT data from the affected limb, resulting in the creation of a three-dimensional model. Subsequently, 3D models of the bones and skin contours, stored as STL format files, were imported into the Materialise Magics 23.0 software for model processing and repair. This facilitated the simulation of reduction and recording of displacement data, effectively generating a "digital prescription" to guide and quantify traditional Chinese medicine manipulation procedures. Finally, a personalized 3D printed splint was applied for fixation treatment. There were 15 males and 10 females in the control group, with an average age of (53.32±5.28) years old. These patients were treated with manualreduction combined with traditional splinting. The clinical efficacy of the two groups was assessed in terms of fracture reduction quality, fracture healing time, Gartland-Werley wrist joint score and X-ray parameters (palminclination angle, ulnar deviation angle, radius height) at 6 weeks post-operatively. Results The treatment group exhibited a shorter duration for achieving clinical healing compared to the control group (P<0.05). Six weeks post-operatively, the treatment group demonstrated higher wrist joint function scores, and a higher proportion of excellent and good outcomes than the control group(P<0.05). The treatment group was superior to the control group in terms of imaging parameters 6 weeks post-operatively (P<0.05). Conclusion By quantifying skin contours through digital simulation prescription reduction, a personalized 3D printed splint is developed to effectively stabilize fractures, enhancing localized fixation while ensuring greater adherence, stability, and comfort. This innovative approach offers personalized treatment for AO type-A distal radius fractures and presents a novel, precise treatment strategy for consideration.

The Effects of Light Pressure Instrument-Assisted Soft Tissue Mobilization at Different Rates on Grip Strength and Muscle Stiffness in Healthy Individuals.

CONTEXT: Instrument-assisted soft tissue mobilization (IASTM) is a popular myofascial treatment utilized by health care professionals. Currently, there is a lack of research on the effects of a light pressure IASTM treatment on the forearm region. The purpose of this study was to explore the effects of a light pressure IASTM technique at different application rates on grip strength and muscle stiffness. This study was considered exploratory with the goal of establishing methodology for future controlled studies. DESIGN: Observational pretest and posttest clinical study. METHODS: Twenty-six healthy adults underwent one light pressure IASTM treatment to their dominant forearm muscles. Participants were allocated to 2 groups of 13 based upon treatment rate: 60 beats per minute and 120 beats per minute. Participants were tested pretreatment and posttreatment for grip strength and tissue stiffness via diagnostic ultrasound. One-way analyses of covariance were used to assess group differences posttreatment for grip strength and tissue stiffness. RESULTS: Statistically significant posttreatment changes for grip strength and tissue stiffness were not found. Despite the nonstatistical significance, there were small decreases in grip strength and tissue stiffness. Faster (120 beats/min) IASTM application may have produced clinically meaningful decreases in grip strength along with a small decrease in tissue stiffness. CONCLUSIONS: This report helps to establish methodology for future controlled studies on this topic. Sports medicine professionals should consider these results as exploratory and interpret them with caution. Future research is needed to confirm these findings and begin to postulate possible neurophysiological mechanisms.

The effects of spin-orbit coupling on optical properties of monolayer [Formula: see text] due to mechanical strains.

We have studied the optical conductivity of a quasi two-dimensional [Formula: see text] in the presence of external magnetic field and spin-orbit coupling. Specially, we address the frequency dependence of optical conductivity due to spin-orbit interaction. Using linear response theory the behavior of optical conductivity has been obtained within Green's function method. We have also considered the effects of uniaxial and biaxial in-plane strain on the optical absorption of [Formula: see text] layer. In the absence of external magnetic field with negative uniaxial strain parameter, optical conductivity includes Drude weight at zero frequency limit while Drude weight vanishes for [Formula: see text] layer under positive uniaxial strain. Our results show that the increase of uniaxial positive strain parameter causes to move the position peak to the higher frequencies. In contrast to uniaxial strain case, the Drude weight in optical conductivity appears at positive biaxial strain value 0.15. Also we have studied the effects of magnetic field, electron doping, hole doping in the presence of spin-orbit coupling on frequency dependence of optical conductivity of [Formula: see text] in details. The magnetic field dependence of optical absorption shows a monotonic decreasing behavior for each value of temperature in the absence of strain parameter.

Effect of Using the Modified Milch Technique on Quality of Life in Patients with Anterior Dislocation of the Shoulder Joint.

Objective: To evaluate the effect of the Milch technique on quality of life (QoL) in patients with anterior dislocation of the shoulder joint. Methods: A total of 126 patients undergoing manual reduction for anterior dislocation of the shoulder in our hospital from January 2021 to January 2022 were prospectively enrolled in this study. The randomized number table method was used to divide patients into the study group (63 patients) and the control group (63 patients). The study group was treated with a modified Milch technique while the control group was treated with the Hippocratic method. Success rate and complications were compared to evaluate the effectiveness of manual reduction. Clinical assessment of shoulder function included the Constant-Murley Score and visual analog scale (VAS) before, during and after manual reduction. Results: The success rate of primary and secondary reduction in the study group was significantly higher than in the control group (87.30% vs 61.90, respectively; P = .001; 11.11% vs 25.40%, respectively; P = .038). The failure rate in the study group was significantly lower than in the control group (1.59% vs 12.70%, respectively; P = .015). The time required for reduction in the study and control groups was 58.87 ± 7.92 seconds and 93.09 ± 8.01 seconds, respectively; a significant difference (t = -24.113; P < .001). There was no statistically significant difference in VAS scores before and during reduction in the 2 groups. After reduction, VAS scores in the study group were significantly lower than in the control group (1.02 ± 0.01 vs 1.14 ± 0.26, respectively; P < .001). There were no significant differences in pain level, activities of daily living, joint range of motion or muscle strength between the 2 groups before and after reduction (P > .05). After reduction, health status, emotional function, mental health, physiological function, physiological function, physical pain, vitality and social function scores in the study group were significantly higher than in the control group (P < .05). There were 4 avulsion fractures and 2 humeral fractures in the control group; no complications occurred in the study group, with a significant difference (χ2 = 6.289; P = .012). Conclusion: The Milch technique can improve the QoL in patients with anterior dislocation of the shoulder, and the success rate of the reduction is high.

This article addresses a fuzzy event-triggered tracking control problem of unreliable networked systems. An event-based tracking controller is put forward to control the plant in fuzzy form. The looped Lyapunov-Krasovskii functional method is made use of conducting stability analysis, and sufficient conditions on the controller are determined. As a result, the tracking control performance is achieved for the controlled system. The feasibility of the presented tracking control design is verified by some examples.

Effect of traditional Chinese manipulation on ankle sprains: A systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis was performed to evaluate the clinical efficacy and safety of traditional Chinese manipulation in treating ankle sprains. METHODS: Seven databases were searched from inception to July 2020. A meta-analysis of randomized controlled trials comparing traditional Chinese manipulation and other conservative therapy for ankle sprains was conducted. The Cochrane Handbook tool was applied to access the quality and risk of bias of each study. The meta-analysis was performed with Review Manager 5.3 software (Nordic Cochrane Centre, Copenhagen, Denmark). RESULTS: In total, 14 articles and 1112 patients were included. The total effective rate of ankle manipulation was much higher than that of other conservative therapy (risk ratio [RR], 1.23; 95% confidence interval [CI], 1.17-1.30; P < .00001). The Baird-Jackson score (RR, 10.14; 95% CI, 5.57-14.70; P < .0001), visual analog scale score (RR, -1.78; 95% CI, -3.14 to -0.43; P = .01), and American Orthopaedic Foot and Ankle Society ankle-hindfoot score (RR, 15.70; 95% CI, 12.72-18.68; P < .00001) were significantly lower in the manipulation group than in the control group. Further subgroup analysis showed that the visual analog scale score of the rotating-traction-poking manipulation was significantly lower than that of the control group (RRRTPM, -2.56; 95% CI, -4.54 to -0.58; P = .01), while there were no significant differences between the effects of other manipulations and the control group (RRother manipulation, -0.62; 95% CI, -1.52 to 0.28; P = .18). CONCLUSION: Traditional Chinese manipulation might have a better effect on ankle sprains than other types of conservative treatment. The rotating-traction-poking manipulation might achieve better effects than other manipulation techniques in terms of alleviating pain intensity. However, considering the overall high or unclear risk of bias, the evidence identified does not allow for a robust conclusion concerning the efficacy and safety of traditional Chinese manipulation for treating ankle sprains. High-quality randomized controlled trials are needed to confirm these findings.

A Cluster-based Model Using Functional Methods Requires Less Operator Experience for Reliable Gait Analysis: A Preliminary Study of Intra- and Inter-assessor Reliability.

Reliability of three-dimensional gait analysis is important for repetitive assessments in clinical or research studies. In this paper, we hypothesized that a Strathclyde Functional Cluster Model (SFCM) in which all the joint centers and flexion axes were determined by functional methods, could improve the reliability of joint kinematics within and between operators' sessions compared to an anatomical model, Plug-in Gait (PiG). A preliminary study of intra- and inter-assessor reliability of the SFCM was been analyzed and compared to the PiG. One able-bodied participant performed eight sessions measured by four operators who have different experience level on the two models. Intra- and inter-operator reliability of the SFCM and PiG were assessed using the intraclass correlation coefficient (ICC) and standard deviation (SD). Results showed that the SFCM generated smaller SD and greater ICC values for all joint variables compared to the PiG in the inter-operator condition, suggesting that functional methods could improve the inter-operator reliability. Moreover, the intra-operator ICC results indicated that the SFCM performance was less influenced by operator experience compared to the PiG. In conclusion, as the model requires less palpation of ALs, it would benefit the users who have less experience in practical use.

The Use of Osteopathic Manipulative Medicine in the Management of Recurrent Mastitis.

Mastitis affects breastfeeding mothers everywhere and management obstacles often lead to cessation of breastfeeding. Breastfeeding mastitis is commonly managed with antibiotics despite lack of clear infectious etiology. With the emerging problem of antibiotic resistance, novel managements are required. We present the case of a 34-year-old woman with 6 pregnancies and 3 children (gravida 6, parity 3) who had 5 cases of mastitis within 6 months treated with multiple courses of antibiotics. The patient underwent with osteopathic manipulative treatment (OMT) to the affected breast over 2 sessions and was taught how to perform self-myofascial release. Techniques are shown in an accompanying Supplemental Video. As of this report, the patient had been symptom free for 1 year. Future research, including a clinical trial of OMT, is required to determine whether osteopathic physicians can effectively manage recurrent lactational mastitis.

A systematic review of pre-hospital shoulder reduction techniques for anterior shoulder dislocation and the effect on patient return to function.

PURPOSE: The majority of acute anterior shoulder dislocations are sustained during sports and wilderness activities. The management of acute dislocations in the pre-hospital setting is currently without guidelines based on the evidence. The study aims to assess the risk of acute complications in pre-hospital shoulder reduction and identify which pre-hospital reduction technique has the highest success rate in the published literature. METHODS: The involved databases were Allied and Complementary Medicine, CENTRAL, CINAHL, Cochrane Database of Systematic Reviews, Embase, Europe PMC, Ovid MEDLINE®, Pedro, Proquest, Trip, and World Health Organization International Clinical Trials Registry platform. Only original research of high methodological quality was included, which was defined by the recently developed assessment tool-assessing the methodological quality of published papers (AMQPP) and investigated the management of acute anterior shoulder dislocations in the pre-hospital setting. RESULTS: Two hundred and ninety-eight articles were identified and screened. A full text review was performed on 40 articles. Four articles published between 2015 and 2018 met the inclusion criteria. A total of 181 patients were included with the study duration ranging from 6 to 60 months. All studies reported zero immediate complication following pre-hospital reduction and there were no documented subsequent adverse events regardless of the technique used. Prompt resolution of neurological symptoms was observed following the early and successful pre-hospital reduction. First attempt success rate, when performed by skilled practitioners, ranged from 72.3% to 94.9%. CONCLUSION: Pre-hospital shoulder reduction appears to be a safe and feasible option when carried out with the appropriate expertise. A novel reduction technique adapted from the mountain medicine diploma course at the University of Paris North was found to have the highest first attempt reduction success rate of 94.9%. Other techniques described in the literature included Hippocratic, Stimson's, Counter-traction and external rotation with the success rates ranging from 54% to 71.7%.

Impact of Extremity Manipulation on Postural Sway Characteristics: A Preliminary, Randomized Crossover Study.

OBJECTIVE: Evaluate multisegmental postural sway after upper- vs lower-extremity manipulation. METHODS: Participants were healthy volunteers (aged 21-40 years). Upper- or lower-extremity manipulations were delivered in a randomized crossover design. Postural assessments were made pre-post manipulation, in floor and rocker board conditions. Analysis included traditional balance measures of pathlength and range and sample entropy (SampEn) to examine the temporal structure of sway of the head, trunk, and surface. RESULTS: No statistical changes in pathlength or sway range on the ground surface condition were observed. No increases in the amount of sway occurred in any condition. Chiropractic manipulation of either upper or lower extremities led to reductions in traditional measures of postural control on the rocker board. In the anteroposterior direction (sagittal plane), lower-extremity manipulation led to increased trunk SampEn while on the ground, and conversely a decreased SampEn while on the rocker board. In the mediolateral rocker board condition (frontal plane), manipulation elicited a change in SampEn that differed according to site of manipulation; upper-extremity manipulation increased SampEn, whereas lower-extremity manipulation reduced SampEn. CONCLUSION: Both upper- and lower-extremity manipulation influenced several measures of postural sway on both the ground and the rocker board. Lower-extremity manipulation improved the organization of sway at the trunk (anteroposterior direction) and the board (mediolateral direction). Given the reduction and reorganization of sway metrics seen in this study, we propose extending this line of research to the elderly who are at greatest risk of increased sway and falls.

Effects of Tibiofibular and Ankle Joint Manipulation on Hip Strength and Muscle Activation.

OBJECTIVES: The purpose of this study was to determine whether high-velocity, low-amplitude ankle region manipulations could increase force output and muscle activation of hip musculature in individuals with a history of ankle sprain and unilateral tensor fascia latae (TFL) weakness during muscle testing. METHODS: This investigation used a single-arm repeated measures design. Twenty-five participants' force outputs were tested at three time points (before manipulation, immediately after manipulation, and 48 hours after manipulation), and muscle activation of the rectus femoris, gluteus medius, and TFL was measured before and immediately after manipulation. Manipulations were applied to the talocrural, subtalar, proximal, and distal tibiofibular joints of the weaker limb. No contralateral manipulations were applied. Two-way repeated measures analysis of variance was used to compare maximal and average force production for each limb. In addition, paired t tests were used to compare muscle activation before and after manipulations. RESULTS: There was a significant limb × time interaction. The involved limb average force increased from before manipulation (65.7 N) to 48 hours after manipulation (77.8 N; P = .014), maximal force increased (76.9 N) 48 hours after manipulation (87.8 N; P = .030), and gluteus medius activation increased (9.8% maximum, 12.2% average) immediately after manipulation. No significant differences were found in the uninvolved limb. CONCLUSION: The results of this study suggest that high-velocity, low-amplitude ankle region manipulations might improve hip abductor strength in individuals with a history of ankle sprain and unilateral weakness during a TFL muscle test.

The Role of Sphenobasilar Synchondrosis in Disease and Health.

BACKGROUND: The sphenobasilar synchondrosis (SBS; also, sphenobasilar synostosis or sphenooccipital synchondrosis) plays a major role in the concept of osteopathic cranial manipulative medicine (OCMM) and craniosacral therapy. Previous research suggests that many individuals, from newborns to adults, present with single or multiple SBS strain patterns as a result of the birth process and other traumatic forces throughout life. To date, it is unclear whether specific SBS lesion patterns are present in altered health states and disease and how they compare with healthy controls. OBJECTIVE: To identify research that reports on specific SBS strain patterns compared with healthy controls. METHODS: A literature review of electronic databases and hand-search of publication bibliographies was performed. Observational studies of newborns, children, and adults were included if there was information on the occurrence of cranial strain patterns related to the SBS in individuals with impaired health states and a healthy control group. RESULTS: Of 1123 citations, 836 articles were screened after duplicate removal, and 42 articles were evaluated by full-text assessment. Three articles were included in this review, including 1 prospective and 2 retrospective studies. The age ranges of the populations studied were newborns aged 5 days or younger, children aged 4 to 14 years, and adults aged 45 to 90 years. In adults with Parkinson disease, no significant difference in SBS strain patterns between the Parkinson disease group and the age-matched healthy control group were seen. In contrast, different SBS strain patterns were observed between newborns with a range of health impairments, such as jaundice and respiratory and nervous symptoms, and children with learning disabilities compared with their healthy counterparts. However, no statistical analysis was conducted in these 2 studies; hence, results are difficult to interpret. Reporting in all 3 studies was limited; therefore, the methodologic quality of the 3 identified studies was deemed incapable of being judged. CONCLUSION: The study landscape of this review highlights the scarcity of, poor reporting on, and unclear methodologic quality of research on SBS strain patterns in disease and health. It is still unclear whether and to what extent specific SBS strain patterns occur in impaired health states compared with healthy controls. Future studies should seek to improve study methods and reporting and minimize the risk of bias.

Treatment of Neck Pain With Myofascial Therapies: A Single Blind Randomized Controlled Trial.

OBJECTIVE: This study aimed to investigate the effects of myofascial release therapy vs a standard physical therapy program in patients with neck pain (NP). METHODS: This was a randomized controlled trial in which 54 participants with mechanical NP were randomly assigned into an experimental group (EG) or a comparison group (CG). The EG group (n = 27) received 5 therapy sessions of myofascial release therapy while the CG group (n = 27) received 10 sessions of massage, ultrasound therapy, and transcutaneous electric nerve stimulation over a 2-week period. Outcome measures were the numerical pain rating scale (NPRS), pressure pain thresholds (PPTs) and range of motion at the end of treatment and at 1-month follow-up. RESULTS: At 1-month follow-up, between-group differences in change scores were found in the NPRS (mean = -1.56, 95% confidence interval [CI] [-2.30 to -0.81]; P < .001), in the right thoracic PPT (mean = 0.35, 95% CI [0.03-0.66]; P = .031), and in both left (mean = 0.34, 95% CI [0.08-0.61]; P = .012) and right (mean = 0.29, 95% CI [0.04-0.54]; P = .026) suboccipital PPTs. The success rate was 63.0% in the CG and 92.6% in the EG. The number needed to treat was 3.38 (95% CI = 1.99-11.23). CONCLUSIONS: Myofascial release therapy could be better than a standard physical therapy program for improving pain and suboccipital PPTs in patients with NP. However, the difference between both treatments is less than the minimum detectable change of the NPRS.

Tibiofemoral joint mobilizations following total knee arthroplasty and manipulation under anesthesia.

STUDY DESIGN: Case report. BACKGROUND: The purpose of this case report is to describe the use of tibiofemoral joint mobilizations to improve knee flexion in a patient with arthrofibrosis following total knee arthroplasty (TKA) and failed manipulation under anesthesia (MUA). CASE DESCRIPTION: A 62-year-old female presented to physical therapy 15 days after TKA with full knee extension, 45 deg of active knee flexion, 48 deg of passive knee flexion, pain, and a Lower Extremity Functional Scale (LEFS) score of 28. INTERVENTIONS/OUTCOMES: A multimodal intervention strategy was used initially with minimal improvement in knee flexion. The patient was diagnosed with fibrosis and MUA was performed. Passive knee flexion was 80 deg before MUA and 75 deg after MUA. Focused grade III and IV tibiofemoral joint mobilizations were used after MUA. At discharge, the patient had 90 deg of active and 116 deg of passive knee flexion, no pain, and an LEFS score of 80. DISCUSSION: A conventional multimodal intervention approach was ineffective for a patient who developed arthrofibrosis following TKA. A focused intervention approach of grade III and IV tibiofemoral joint mobilizations improved knee flexion, pain, and function following TKA and failed MUA.

Instrument-Assisted Soft Tissue Mobilization: A Systematic Review and Effect-Size Analysis.

OBJECTIVE: To determine the overall effectiveness of instrument-assisted soft tissue mobilization (IASTM) in improving range of motion (ROM), pain, strength, and patient-reported function in order to provide recommendations for use. We also sought to examine the influence of IASTM on injured and healthy participants, body part treated, and product used. DATA SOURCES: We searched the Academic Search Premier, Alt Healthwatch, CINAHL Complete, Cochrane Library, MEDLINE with full text, NLM PubMed, Physical Education Index, Physiotherapy Evidence Database (PEDro), SPORTDiscus with full text, and Web of Science databases for articles published from 1997 through 2016. The Boolean string advantEDGE OR astym OR graston OR iastm OR "instrument assist* soft tissue mobil*" OR "augment* soft tissue mobil*" OR "myofascial release" OR "instrument assist* massage" OR "augment* massage" OR "instrument assist* cross fiber massage" was used. STUDY SELECTION: Included articles were randomized controlled trials that measured ROM, pain, strength, or patient-reported function and compared IASTM treatment with at least 1 other group. DATA EXTRACTION: Thirteen articles met the inclusion criteria. Four independent reviewers assessed study quality using the PEDro and Centre for Evidence-Based Medicine scales. Twelve articles were included in the effect-size analysis. DATA SYNTHESIS: The average PEDro score for studies of uninjured participants was 5.83 (range = 5 to 7) and that for studies of injured participants was 5.86 (range = 3 to 7). Large effect sizes were found in outcomes for ROM (uninjured participants), pain (injured participants), and patient-reported function (injured participants). The different IASTM tools used in these studies revealed similar effect sizes in the various outcomes. CONCLUSIONS: The current literature provides support for IASTM in improving ROM in uninjured individuals as well as pain and patient-reported function (or both) in injured patients. More high-quality research involving a larger variety of patients and products is needed to further substantiate and allow for generalization of these findings.

Force transmission between thoracic and cervical segments of the spine during prone-lying high-velocity low-amplitude spinal manipulation: A proof of principle for the concept of regional interdependence.

BACKGROUND: Regional interdependence is conceptually based on observations that applying manual therapy to a remote anatomical region has an effect in the area of the patient's primary complaint. The current model for regional interdependence depends on force transmissibility within the body. This investigation sought to determine transmissibility between forces applied to the thoracic spine during prone-lying high-velocity low-amplitude spinal manipulative therapy and the cervical spine. METHODS: A chiropractic treatment table was modified to allow (or disallow) translation of the headrest in the caudal-cephalad direction when unlocked (or locked). Prone-lying high-velocity low-amplitude spinal manipulative therapy was applied to the thoracic region of 9 healthy participants with the headrest in both configurations. Head and thorax kinematics and kinetics were measured at interfaces between participant and the external environment, which included the clinician's hands. Compressive forces at the cervicothoracic junction and angular kinematics of the cervical spine were derived. Ratios between the clinician-applied forces (input) and the cervical compressive force (output) were also determined. FINDINGS: The cervical spine extended during all high-velocity low-amplitude spinal manipulative therapy trials. Force input-to-output ratios exceeded 1 for high-velocity low-amplitude spinal manipulative therapy trials performed with the headrest in the locked configuration, which was greater than ratios for the unlocked configuration. INTERPRETATION: Forces imparted to thoracic spine during high-velocity low-amplitude spinal manipulative therapy were transmitted to the cervical spine, which provided a precursor for the regional interdependence model for manual therapy. Friction between the participant's face and the treatment table's head rest likely amplified cervical compressive forces.

Three-step Reduction Therapy of Integrated Chinese and Western Medicine for Thoracolumbar Burst Fracture.

Objective: To investigate and compare the efficacy of three-step reduction (TSR) therapy of integrated Chinese and Western Medicine and posterior open (PO) surgery for thoracolumbar burst fracture. Methods: We selected 60 patients diagnosed with thoracolumbar burst fracture and received treatment in our hospital from December 2014 to March 2017. According to randomized digital table, they were randomly divided into TSR and PO groups. VAS pain grade, Oswestry disability index, height of centrum front, Cobb's angle of spine, bleeding, and complication of internal fixation of the two groups were compared. Results: Postoperative reduction of injured centrum, regained volume of canalis vertebralis, volume of bleeding, and early functional rehabilitation of TSR group were better than that of PO groups (P < 0.05). Conclusion: Through three-step reduction combined pedicle screw fixation surgery, we can achieve satisfied reduction of thoracolumbar burst fracture, rebuild the height of centrum, recover the biomechanics function of spine, and reduce bleeding. Three-step reduction therapy is an effective therapy for thoracolumbar burst fracture.
