ABSTRACT
Objetivo: A pesquisa tem por objetivo verificar os limiares de repouso eletromiográfico dos músculos masseter e temporal em pacientes com disfunção temporomandibular (DTM) antes e após intervenção fonoaudiológica com e sem a utilização de bandagem elástica terapêutica. Métodos: A coleta contou com 14 participantes do sexo feminino, com idade entre 18 e 40 anos, com diagnóstico de DTM muscular ou mista. As pacientes foram divididas entre dois grupos classificados em: pacientes com bandagem associada à terapia tradicional (CB) e grupo de terapia tradicional (SB). As pacientes inicialmente foram avaliadas pelo exame de eletromiografia de superfície nas situações de contração voluntária máxima e repouso, e após quatro semanas de intervenção, foi realizada nova avaliação com os mesmos instrumentos. A análise dos dados ocorreu de forma quantitativa e qualitativa. Resultados:No grupo SB o músculo masseter direito apresentou aumento dos valores de repouso com significância, foi observado que o mesmo ocorreu para todos os músculos deste grupo, influenciando no equilíbrio da musculatura ipsilateral e contralateral, no entanto sem evidência estatística. O grupo CB não demonstrou valores estatísticos significativos, porém qualitativamente os valores de repouso muscular diminuíram e equilibraram-se de forma contralateral. Conclusão: Não foram observadas mudanças estatisticamente significantes nos limiares eletromiográficos durante repouso dos músculos masseter e temporal em ambos os grupos. Qualitativamente houve aumento dos valores eletromiográficos após terapia manual tradicional em todos os músculos do grupo SB. Com relação ao grupo CB, houve diminuição dos valores do repouso eletromiográfico após terapia, embora sem evidências estatísticas. (AU)
Purpose: Objective: The research aims to verify the electromyographic rest thresholds of the masseter and temporal muscles in patients with temporomandibular disorders (TMD) before and after speech therapy intervention with and without the use of therapeutic elastic bandage. Methods: The collection included 14 female participants, aged between 18 and 40 years, who had a diagnosis of muscular or mixed TMD. The patients were divided into two groups: with traditional therapy (CB) bandage and traditional therapy (SB) only group. The patients underwent initial evaluation, as well as surface electromyography in situations of maximum voluntary contraction and rest and at the end of the four weeks of intervention, a new evaluation was performed with the same instruments. Data analysis occurred quantitatively and qualitatively. Results: In the SB group, the right masseter muscle showed a significant increase in resting values. It was observed that the same occurred for all muscles in this group, influencing the balance of the ipsilateral and contralateral muscles, although without statistical evidence. The CB group did not show statistically significant values, but qualitatively the muscle rest values decreased and balanced in a contralateral way. Conclusion: No statistically significant changes were observed in the resting electromyographic thresholds of the masseter and temporalis muscles in both groups. Qualitatively, there was an increase in electromyographic values after traditional manual therapy in all muscles in the SB group. Regarding the CB group, there was a decrease in electromyographic resting values after therapy, although without statistical evidence. (AU)

Purpose: To compare post?operative pain perception using bandage contact lens (BCL) stored at 2–8?C (Cold BCL, CL?BCL) or room temperature (23 – 25?C, RT?BCL) after photorefractive keratectomy (PRK) or corneal collagen?crosslinking (CXL) and determine status of nociception associated factors. Methods: In this prospective interventional study, 56 patients undergoing PRK for refractive correction and 100 keratoconus (KC) undergoing CXL were recruited following approval from the institutional ethics committee with informed consent. Patients undergoing bilateral PRK received RT?BCL on one eye and CL?BCL on the other. Pain was graded by Wong–Baker scoring on the first post?operative day (PoD1). Expression of transient receptor potential channels (TRPV1, TRPA1, TRPM8), calcitonin gene?related peptide (CGRP) and IL?6 was measured in cellular content from used BCLs collected on PoD1. Equal number of KC patients received RT?BCL or CL?BCL post?CXL. Pain was graded by Wong–Baker scoring on PoD1. Results: Pain scores on PoD1 were significantly (P < 0.0001) reduced in subjects receiving CL?BCL (Mean ± SD: 2.6 ± 2.1) compared to RT?BCL (6.0 ± 2.4) post?PRK. 80.4% of subjects reported reduced pain scores with CL?BCL. 19.6% reported no change or increased pain scores with CL?BCL. TRPM8 expression was significantly (P < 0.05) increased in BCL of subjects reporting reduced pain with CL?BCL compared to those who did not. Pain scores on PoD1 were significantly (P < 0.0001) reduced in subjects receiving CL?BCL (3.2 ± 2.1) compared to RT?BCL (7.2 ± 1.8) post?CXL. Conclusion: The simple approach of using a cold BCL post?operatively substantially reduced pain perception and could overcome post?operative pain?related limited acceptance of PRK/CXL.
ABSTRACT
AIM:To assess the clinical efficacy of 5-fluorouracil(5-FU)and bandage contact lens in the pterygium excision combined with autogenous limbal stem cell transplantation(ALSCT)in treating patients with pterygium.METHODS:Random controlled clinical trial. A total of 71 patients(71 eyes)of pterygium who treated at the department of ophthalmology in Qinhuangdao Haigang Hospital between May 2021 and November 2022 were included. They were divide into three groups, including 23 eyes received pterygium excision combined with ALSCT in group A, 24 eyes that were administered with 5-FU intraoperatively and postoperatively in group B, and 24 eyes that received both bandage contact lens and 5-FU in group C. Furthermore, comfort levels at 1, 3, 7, 14d postoperatively, corneal epithelial healing at 1, 3, 7, 14d and 1mo postoperatively, treatment outcomes and complications at 3～6mo postoperatively were compared among the three groups of patients.RESULTS:The comfort levels at 1, 3 and 7d postoperatively and corneal healing at 1 and 3d postoperatively of the group C were better than those of the groups A and B. There were no statistical significant differences in the comfort levels at 14d after surgery and corneal healing at 14d and 1mo after surgery among the three groups of patients. Over a 3～6mo follow-up period, group A experienced recurrence in 3 eyes, group B had 1 recurrence, while group C had no recurrence. There were no statistically significant differences in complication rates among the three groups of patients.CONCLUSIONS: The application of 5-FU combined with bandage contact lens can enhance postoperative comfort levels, promote corneal epithelial healing, and improve the success rate in pterygium excision combined with ALSCT.
ABSTRACT
ObjectiveTo investigate the short-term efficacy of orthopedic elastic bandages on gait symmetry and walking ability in children with spastic hemiplegic cerebral palsy. MethodsFrom June, 2020 to June, 2023, 31 children with spastic hemiplegic cerebral palsy from Beijing Bo'ai Hospital were randomly divided into control group (n = 15) and experimental group (n = 16). Both groups received routine rehabilitation, while the control group received routine walking training, and the experimental group wore an orthopedic elastic bandage for walking training, for four weeks. The indexes of gait symmetry of foot deviation angle ratio (affected/healthy), step length ratio (affected/healthy), gait line ratio (affected/healthy) and standing stage ratio (affected percentage/healthy percentage) were calculated before and after training, and they were measured step width and the optional and maximum walking speed of 10-meter walk test (10MWT). ResultsOne case dropped off in the experimental group. After training, the foot deviation ratio, step length ratio, gait line ratio, and standing stage ratio improved in both groups (|t| > 2.434, P < 0.05), and they were better in the experimental group than in the control group (|t| > 2.230, P < 0.05); while the optional and maximum walking speed of 10MWT improved in both groups (|t| > 9.186, P < 0.001), and they were better in the experimental group than in the control group (|t| > 2.278, P < 0.05). ConclusionWearing orthopedic elastic bandages during rehabilitation can promote the gait symmetry and walking ability of children with spastic hemiplegic cerebral palsy.

ABSTRACT
Objective:To explore the clinical effectiveness of hemostatic bandage on wound safety and comfort after transradial coronary angiography and/or interventional therapy.Methods:This was a experimental study. A total of 400 consecutive patients who underwent transradial coronary angiography and/or interventional therapy in the Department of Cardiology, Peking University Third Hospital from July to October 2022 were enrolled and randomly divided into the hemostatic bandage group and the hemostatic balloon compressor group by the envelope method with 200 cases in each group. The hemostatic bandage group and the hemostatic balloon compressor group were treated with hemostatic bandage and hemostatic balloon compressor as transradial artery hemostatic device, respectively, to observe and compare postoperative hemostatic effect, hemostat use time, complication rate, postoperative pain, the degree of numbness in the finger on the operated side and wristband comfort between the two groups.Results:The hemostatic success rate was 98.5% (197/200) and 99.0% (198/200) in the hemostatic bandage and the hemostatic balloon compressor group, respectively, with no statistical difference ( χ2=0.20, P>0.05). The hemostat use time in the hemostatic bandage group and the hemostatic balloon compressor group was (6.23 ± 0.47) h and (17.01 ± 7.74) h, respectively, and the difference was statistically significant ( t=-19.66, P<0.01). The incidence of complications in the hemostatic bandage group and the hemostatic balloon compressor group was 13.5%(27/200) and 29.5%(59/200), respectively, and the difference was statistically significant ( χ2=8.01, P<0.05). Among the complications, swelling occurred in 21 individuals of the hemostatic bandage group and 54 individuals of the hemostatic balloon compressor group with statistically significant differences ( U=16 689.50, P<0.01). Besides, the hemostatic bandage group was significantly better than the hemostatic balloon compressor group with statistically significant differences in wound pain at immediate postoperative ( U=13 669.50, P<0.01), in finger numbness at immediate postoperative and 1-hour postoperative (immediate postoperative: U=17 838.00, P<0.05; 1-hour postoperative: U=13 342.50, P<0.01), in comfort at immediate postoperative, 4-hours, 8-hours and 12-hour postoperative(immediate postoperative: U=9 966.50, P<0.01; 4-hour postoperative: U=12 851, P<0.01; 8-hour postoperative: U=14 900, P<0.01; 12-hour postoperative: U=15 920, P<0.01). Conclusions:The hemostatic bandage shows better hemostatic effect, shorter compression time, lower complication rate, less wound pain, less numbness of the finger on the operation side, and higher comfort of the wrist band compared to hemostatic balloon compressor after transradial coronary angiography and/or interventional therapy, which is worthy of clinical promotion.
ABSTRACT
PURPOSE@#The present study aimed to treat fractures of the distal end of the radius in children with Robert Jones (RJ) bandage. The objective was to compare this treatment modality with the cast regarding the frequency of the complication occurrence, child comfortability, and family satisfaction.@*METHODS@#The study was a randomized controlled non-inferiority clinical trial including children with recent (less than 5 days) fractures at the distal end of the radius OTA/AO 23-A2, which is usually treated conservatively. Those with open fractures, pathological fracture, severely displaced fracture that needs reduction or multiple injuries were excluded. The participants were divided randomly into 2 groups according to the treatment modalities. Group 1 was treated by plaster of Paris cast (the control group), and Group 2 by modified RJ bandage (the trial group). The difference between the 2 groups was found by the Chi-squared test. The difference was considered statistically significant when the p value was less than 0.05.@*RESULTS@#There were 150 children (aged 2 - 12 years, any gender) included in the study, 75 in each group. The complications occured in 5 (3.3%) cases only, pressure sores of 3 cases in Group 1 and fracture displacement of 2 cases in Group 2. There was no statistically significant difference in the rate of complication occurrence between both modalities of treatment (p = 0.649). Children treated by RJ bandages were more comfortable than those treated by the cast (97.3% vs. 73.3%, p < 0.001) with a statistically significant difference between them. Contrary to that, the families were more satisfied with the cast than RJ bandage (88.0% vs. 81.3%), but without a statistically significant difference (p = 0.257).@*CONCLUSION@#RJ bandage is a non-inferior alternative to the cast for the treatment of fractures at the distal end of the radius that can be treated conservatively in children.

All patients received complex decongestion therapy. At the pressure bandage stage, the control group received figure-of-eight shape bandaging methods, the experimental group implemented modified bandaging methods: the figure-of-eight shape bandaging methods was used below the elbow joint, the spiral bandaging methods was used above the elbow joint. The arm circumference of affected limb, extracellular water/total body water ratio, general comfort questionnaire, bandage loosening rate as well as bandage loss was compared between two groups.Results:At 20 days after treatment, the arm circumference of affected limb in L 3, L 4 were (20.69 ± 2.06) cm, (25.76 ± 3.79) cm and extracellular water/total body water ratio was (10.15 ± 2.49)% in the experimental group, which were lower than those in the control group (21.97 ± 3.45) cm, (27.33 ± 3.25) cm and (11.67 ± 3.12)%, the differences were significant ( t=2.13, 2.11 and 2.56, all P<0.05); the physiological demension scores and total general comfort questionnaire scores were (11.07 ± 2.09) points and (81.71 ± 5.65) points in the experimental group, which were higher than those in the control group (8.36 ± 2.28) points and (77.29 ± 7.52) points, the difference were statically significant ( t=5.88 and 3.16, P<0.05). The bandage loosening rate was 2.2% in the experimental group, 6.7% in the control group, there was no significant difference between two groups ( χ2=1.05, P>0.05). The average bandage loss was (3.47 ± 0.53) rolls in the experimental group, which was lower than that in the control group (3.79 ± 0.40) rolls, the difference was statically significant ( t=3.28, P<0.01). Conclusions:Modified bandaging methods can decrease breast cancer associated lymphoedema, improve the degree of patient comfort and reduce bandage usage.
ABSTRACT
Objective:To evaluate the efficacy and safety of corneal bandage lens in the treatment of dry eye after cataract surgery in patients with mild meibomian gland dysfunction (MGD).Methods:A non-randomized controlled clinical study was conducted.Sixty eyes of 60 patients with mild MGD after cataract surgery were enrolled in Yantai Yuhuangding Hospital from June 2020 to February 2021.The patients were divided into bandage lens group and control group according their willingness, with 30 eyes in each group.All the patients received phacoemulsification and intraocular lens implantation and were administered with the same postoperative medication.Patients in bandage lens group wore lenses for 14 days continuously after the operation.Patients in control group did not wear the corneal bandage lens after the operation.The structure and inflammation of the anterior segment were observed with a slit-lamp microscope before operation and on days 1, 7, and 14 after the operation.Best corrected visual acuity (BCVA) was obtained using a standard logarithmic visual acuity chart.Ocular surface symptoms were evaluated via an ocular surface disease index (OSDI) questionnaire.The intraoperative changes of meibomian glands were assessed with an ocular surface analyzer and the non-invasive first tear film break-up time (NIFBUT) was recorded.Corneal epithelium defects were observed by corneal fluorescein sodium staining (CFS). This study adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Yantai Yuhuangding Hospital (No.2021-363). Written informed consent was obtained from each patient before any medical examination.Results:On the 1st, 7th, and 14th day after surgery, no inflammatory reaction or complication was observed in both groups.Statistically significant differences in BCVA among different postoperative time points were found ( Ftime=3.610, P=0.016). BCVA on the 7th day after surgery were higher than that on the 1st day after surgery, and the BCVA on the 14th day after surgery were significantly higher than those on the 1st and 7th day after surgery in both groups, with statistically significant differences (all at P<0.05). There were statistically significant differences in OSDI scores between the two groups at different postoperative time points ( Fgroup=31.219, P<0.001; Ftime=15.672, P<0.001). The OSDI scores of bandage lens group were significantly lower than those of control group on the 7th and 14th day after surgery, OSDI scores in both groups on the 14th day after surgery were significantly lower than those on the 1st and 7th day after surgery, with statistical significance (all at P<0.05). The NIFBUT values on the 7th and 14th day after surgery were (6.62±0.93)s and (8.02±1.13)s, in control group, bandage lens group and (9.81±0.91)s and (10.03±0.49)s in bandage lens group, with a statistically significant difference between them ( Fgroup=2.351, P=0.037), and the NIFBUT values of bandage lens group on the 7th and 14th day after surgery were higher than those of control group, with statistically significant differences (both at P<0.05). The number of high CFS score eyes of bandage lens group were lower than those of control group on the 7th and 14th day after surgery, and the differences were statistically significant ( χ 2=7.391, P=0.025; χ 2=9.317, P=0.002). Conclusions:For patients with mild MGD after cataract surgery, wearing bandage contact lens has no obvious ocular adverse reaction and can promote the growth of corneal epithelium, enhance the stability of tear film, improve dry eye symptoms, and relieve dry eye manifestations after surgery.
ABSTRACT
Recurrent corneal erosion (RCE), a common disease caused by repeated episodes of corneal epithelial defects, is characterized by the sudden onset of eye pain, usually upon first awakening.Among many causes of the disease, trauma is the most common one, followed by epithelial basement membrane dystrophy.The disease can be diagnosed via the characteristic medical history, ocular symptoms and slit-lamp examination.Treatment of RCE includes both conservative management and surgical management.Conservative treatment is the first choice for the primary patients, including medication, bandage contact lens, application of serum drops, coverage of cryopreserved amniotic membrane, etc.The appropriate surgical procedures should be performed in patients when the conservative therapy failed.Surgical treatment mainly includes epithelial debridement, diamond burr polishing, anterior stromal puncture, alcohol delamination, phototherapeutic keratectomy, photorefractive keratectomy, femtosecond laser-assisted lamellar keratectomy, etc.RCE treatment progress was comprehensively reviewed in this article to provide references for clinical therapy.
ABSTRACT
@#AIM: To evaluate the application effect of limbal stem cell transplantation fixed by corneal bandage lens with no suture method in primary pterygium excision surgery.<p>METHODS:Selected 25 patients of 50 eyes with bilateral primary pterygium who were admitted into our hospital from January 2019 to December 2019 for prospective clinical study. Group A(25 eyes)were randomly chosen with one eye of a patient fixed with corneal bandage lens with no suture; and Group B(25 eyes)were chosen with the other eye of a patient using traditional suture method. The incision healing, patient comfort, surgical complications, and postoperative recurrence were observed in both groups after postoperative follow-up for 6mo.<p>RESULTS: The average operating time for Group A(13.5±2.1min)was significantly less than that of Group B(26.6±7.2min). The results of postoperative follow-up in 1d, 1, 2wk, 1, 3 to 6mo showed that the discomfort such as pain, photophobia, lacrimation, foreign body sensation and itching were lower in Group A than in Group B. The discomfort disappeared in both groups after 6mo. The stability of postoperative corneal rim stem cell transplants was favorable in Group A, and the complications one and three months after surgery were less than those in Group B.<p>CONCLUSION: The method of banded corneal rim stem cell conjunctival transplantation combined with corneal bandage lens is an effective procedure for the treatment of primary pterygium. It is simple, convenient, safe and effective, the postoperative comfort is good, the recurrence rate is low, compared with the traditional suture method, it can shorten the operation time and effectively reduce the patient's pains.
ABSTRACT

ABSTRACT
@#AIM: To analyze the influence of bandage contact lens on corneal refractive status and postoperative complications in patients with pterygium. <p>METHODS: Totally 116 patients with pterygium treated in the hospital between January 2018 and December 2019 were recruited in the study. They were divided into control group and observation group by random number table method, 58 cases in each group. The control group received extended pterygium resection and autologous corneal limbal stem cell transplantation. On this basis, the observation group was treated with bandage contact lens. The best corrected visual acuity(BCVA), surface asymmetry index(SAI)of corneal topography, surface regularity index(SRI), corneal refractive power and postoperative complications in the two groups were compared. <p>RESULTS: Compared with preoperation, the BCVA of the two groups was significantly higher 1mo and 3mo after operation(<i>P</i><0.05), without statistically significant difference between the groups(<i>P</i>>0.05). Corneal horizontal and vertical curvature of the two groups were significantly higher, while corneal astigmatism was significantly lower at 1mo and 3mo after surgery. Meanwhile, the observation group had significantly lower corneal astigmatism than the control group(<i>P</i><0.05). SAI and SRI of the two groups significantly decreased, which were significantly lower in the observation group than in the control group(<i>P</i><0.05). No complications such as infection, poor healing of grafts and subconjunctival cysts were observed. The incidence of eye irritation was significantly lower in the observation group than in the control group, and lower at 2wk than at 1wk before operation(<i>P</i><0.05).<p>CONCLUSION: Extended pterygium resection combined with autologous corneal limbal stem cell transplantation and bandage contact lens is more conductive to the improvement of corneal refraction in patients with pterygium, which also can reduce the incidence of eye irritation.
ABSTRACT
@#AIM: To compare the measurement of intraocular pressure(IOP)through a bandage contact lens with the “native” measurement by rebound tonometry and non-contact tonometry in patients after pterygium excision. <p>METHODS: Fifty consecutive patients(50 eyes)undergone pterygium excision(unilateral nasal, primary pterygium, horizontal length <4mm), and conjunctival autografting were included in this prospective study. IOP measurements were obtained by Rebound tonometry and non-contact tonometry in random order with(lens measurement)and without(native measurement)a bandage contact lens half a month after operation. We compared the mean values(validity parameter)and standard deviation(precision parameter)of the two individual measurements in each case using the paired t-test 14d after surgery. <p>RESULTS: With the rebound tonometry we detected statistically significant higher values in the contact lens measurements(18.20±3.19 <i>vs</i> 15.17±3.80mmHg in the native measurements; <i>P</i><0.001), a good correlation with <i>r</i>=0.884 and mean difference was 3.04±1.79mmHg; With the non-contact tonometry we detected statistically significant higher values in the contact lens measurements(15.74±3.23 <i>vs</i> 13.19±3.89mmHg in the native measurements; <i>P</i><0.001), a good correlation with <i>r</i>=0.876 and mean difference was 2.55±1.88mmHg. In the contact lens measurements and native measurements, we detected statistically significant higher values by Rebound tonometry than that by non-contact tonometry(<i>P</i><0.001), and mean difference was 2.46±1.45mmHg, 1.98±1.67mmHg. <p>CONCLUSION: The use of rebound tonometry and non-contact tonometry shows good consistency between lens measurement and native measurement. However, it should be noted that the average of the measurements over contact lens by rebound tonometry and non-contact tonometry were found to be higher than that in native measurement, and the average of the measurements with and without lens by rebound tonometer was found to be higher than what was measured by non-contact tonometry.

Ocular surface irritation symptom scores, corneal epithelial healing time and conjunctival graft edema subsidence time of the three groups were compared after treatment.<p>RESULTS: Ocular surface irritation symptom scores in group A were lower than those in group C at all observation time points postoperatively(all <i>P</i><0.001); the corneal epithelial healing time(2.08±0.78d)and conjunctival graft edema subsidence time(4.62±1.17d)in group A were significantly shorter than those in group C with corneal epithelial healing time(5.13±2.34d)and conjunctival graft edema subsidence time(6.42±1.51d)(<i>P</i>=0.001, <i>P</i>=0.002). The corneal epithelial healing time was significantly shorterin group A when compared with group B(<i>P</i>=0.018), but there were no significant differences in ocular surface irritation symptom scores and conjunctival graft edema subsidence time between the two groups.<p>CONCLUSION: The combination of 3g/L sodium hyaluronate and corneal bandage contact lens has synergistic effect when applicated in the early stage after pterygium excision surgery, it can effectively shorten the corneal epithelial healing time as well as relieve irritation symptoms.
ABSTRACT
BACKGROUND: The clinical effect of minimally invasive treatment of hallux valgus is significant. The osteotomy end is stabilized only by external fixation of the bandage. There is currently no research on the stability of the osteotomy end. OBJECTIVE: To study the effect of minimally invasive treatment of the "8" bandage external fixation on the stress and displacement of the osteotomy end in the balanced standing condition after hallux valgus. METHODS: In the minimally invasive treatment of the "8" bandage external fixation finite element model after the hallux valgus operation, three vertical axes (X-axis, Y-axis, Z-axis) were established with the first tibial osteotomy as the center. The X-axis and Y-axis were parallel to the horizontal plane of the foot, pointing to the medial and anterior sides of the foot respectively. The Y axis was perpendicular to the horizontal plane of the foot, pointing upwards. The four nodes defining the distal osteotomy surface were A1 on the upper side, B1 on the outer side, and C1 on the outer side, and D1 on the inner lower side. The proximal end osteotomy surface corresponded to four nodes as A2, B2, C2 and D2. The displacement was positive when it coincided with the direction of the coordinate axis, and negative when it was opposite. Through the finite element analysis, the direction and magnitude of the stress and displacement of the distal and proximal nodes of the osteotomy surface in the balanced standing condition were obtained. RESULTS AND CONCLUSION: (1) The finite element model of the "8" bandage after minimally invasive treatment of hallux valgus was used in a balanced standing condition. The maximum stress at the osteotomy end was at the dorsal side of the osteotomy surface (B2), which was 0.632 MPa. (2) The first principal stress at the osteotomy surface was at Z-axis. The direction was opposite to the Z-axis, and was the same as the total stress, which was a compressive stress. The shear force was the largest on the XY plane, and the maximum stress was at the dorsal inner side (A2) of the proximal osteotomy surface, which was 0.058 MPa. (3) The major displacements of the distal and proximal ends of the first patella osteotomy were on the X-axis, and the displacements were on the medial condyle (D1) of the osteotomy surface, i.e., -1.002 mm and medial condyle (A2), and 0.621 mm, respectively. (4) The results confirm that the external fixation of "8" bandage can maintain the stability of the osteotomy end after minimally invasive treatment of hallux valgus, and is conducive to the healing of the osteotomy end.
ABSTRACT
BACKGROUND: Various methods have been developed for establishing a rabbit osteoarthritis model worldwide. However, most of modeling methods are cumbersome, and the original gypsum braking method has some defects. OBJECTIVE: To establish the rabbit osteoarthritis model using polymer bandage combined with a plastic rod. METHODS: Sixteen male New Zealand white rabbits were randomly divided into model group and control group. In the model group, the rabbit osteoarthritis model was established through fixed braking using polymer bandage in the flexion position. The control group was normal group. In the model group, the polymer bandage was removed after 8 weeks of fixation. Histological changes of rabbit synovium, cartilage and meniscus were observed using hematoxylin-eosin staining under microscope. Mankin scoring for articular cartilage was performed. The study protocol was approved by the Animal Ethics Committee of the First Affiliated Hospital of Xinjiang Medical University (approval No. IACUC-20170222026). RESULTS AND CONCLUSION: Under the light microscope, the number of meniscus chondrocytes and stroma in the model group was increased, with part of chondrocytes increased in size, and clearly visible cartilage pits. A small amount of chronic inflammatory cells in synovial tissue infiltrated, the number of collagen fibers increased, and some collagen fibers were thickened with hyaline degeneration. Villous-nodular hyperplasia was visible in part of synovial tissues. There were slight fissures on part of the cartilage surface, chondrocytes and stroma slightly proliferated, the number of chondrocytes and stroma reduced partially, and collagen fibers arranged disorderly. The pathological results showed that there were typical pathological changes of knee osteoarthritis in the knee. The Mankin score of the model group was significantly higher than that of the control group (P < 0.05). Therefore, the use of polymer bandage combined with plastic rod can successfully establish the rabbit model of knee osteoarthritis, with good local fixation stability, joint angle controllability, and good local permeability.
ABSTRACT
BACKGROUND: It is still lack of sufficient clinical evidence whether the patients can benefit from the routine use of elastic bandages after total knee arthroplasty. OBJECTIVE: To explore whether the use of elastic compression bandage after first total knee arthroplasty is beneficial to the prognosis of patients. METHODS: Totally 60 knee osteoarthritis patients who received bilateral knee arthroplasty in the Department of Joint Surgery, West Coast Hospital Branch of Affiliated Hospital of Qingdao University were selected from September 2017 to September 2018. One limb of the patient was covered with a general surgical dressing, while an elastic bandage was applied from the instep to the middle of the thigh (elastic compression bandage group). One limb was covered only with a general surgical dressing (control group). All patients signed the informed consent. The study was approved by the Hospital Ethics Committee. Circumference (thigh, knee and calf), flexural activity (range of motion) and visual analogue scale of the lower extremities were measured at 1, 2, 3 and 7 days after the operation by professionals who were not involved in patient management. Drainage volume 24 hours after operation and the occurrence of complications within 30 days after operation were recorded. RESULTS AND CONCLUSION: (1) At 1, 2, 3, and 7 days after surgery, circumference of thigh, knee and calf was smaller in the elastic compression bandage group than in the control group. Range of motion of the knee was better in the elastic compression bandage group than in the control group (P < 0.001). (2) At 1 and 2 days after surgery, resting visual analogue scale scores were higher in the elastic compression bandage group than in the control group (P < 0.001). At 7 days, resting visual analogue scale scores were lower in the elastic compression bandage group than in the control group (P < 0.001). No significant difference in visual analogue scale scores was found between the two groups at 3 days. Sports visual analogue scale scores in the elastic compression bandage group were higher than in the control group at 1 and 2 days (P < 0.001). However, no significant difference in sports visual analogue scale scores was detected between the two groups at 3 and 7 days. (3) There was no difference in wound-healing complications between the two groups, but the sample size was too small for meaningful statistical analysis. (4) There was a statistically significant difference in drainage volume between the two groups at 24 hours after surgery. (5) No deep infection, venous thrombosis or reoperation occurred within 30 days. (6) It is concluded that the application of elastic compression bandage from the instep to the middle of the thigh after the first total knee arthroplasty can effectively reduce the swelling of the operative limb and postoperative blood loss, increase the flexion and extension of the operative limb, which is conducive to the rapid recovery after the operation. It is worth popularizing and applying.
ABSTRACT
Objective:To observe the effect of compressive low elastic bandage on upper limb lymphedema after breast cancer surgery. Methods:From November, 2017 to December, 2018, 64 patients with upper limb lymphedema after breast cancer surgery were randomly divided into control group (n = 32) and observation group (n = 32). Both groups accepted manual lymphatic drainage and low elastic bandage, while the observation group increased the pressure with sponge pads on the fibrous swelling site as bandaging, five times a week for two weeks. They were measured L-Dex with bioelectrical spectroscopy before the first treatment (T1), before the second treatment (T2), before the third treatment (T3), before the sixth treatment (T4), and 24 hours after the tenth treatment (T5), respectively. The arm circumference of affected side and un-affected side was also measured at T1 and T5. Results:L-Dex decreased since T2 in both groups, but increased at T4 in the observation group and more than that of the control group (t = 2.13, P < 0.05), and less than that of the control group at T5 (t = -2.29, P < 0.05). The difference of arm circumference between affected side and un-affected side was less in the observation group than in the control group (t = -3.78, P < 0.001)。 Conclusion:Low elastic bandage combined with lymphatic drainage technique can alleviate the fibrous swelling. On the basis of low elastic bandage with local sponge pad compression is more effective than simple low elastic bandage on fibrous swelling after lymphedema of upper limbs after breast cancer surgery.
