Pericapsular Nerve Group (PENG) block versus fascia iliaca compartment (FI) block for hip surgery: a systematic review and meta-analysis of randomized controlled trials

Abstract Background: This study compares Fascia Iliaca compartment (FI) block and Pericapsular Nerve Group (PENG) block for hip surgery. Methods: Pubmed, Embase and Cochrane were systematically searched in April 2022. Inclusion criteria were: Randomized Controlled Trials (RCTs); comparing PENG block versus FI block for hip surgery; patients over 18 years of age; and reporting outcomes immediately postoperative. We excluded studies with overlapped populations and without a head-to-head comparison of the PENG block vs. FI block. Mean-Difference (MD) with 95% Confidence Intervals (CI) were pooled. Trial Sequential Analyses (TSA) were performed to assess inconsistency. Quality assessment and risk of bias were performed according to Cochrane recommendations. Results: Eight RCTs comprising 384 patients were included, of whom 196 (51%) underwent PENG block. After hip surgery, PENG block reduced static pain score at 12h post-surgery (MD = 0.61 mm; 95% CI 1.12 to -0.09; p = 0.02) and cumulative postoperative oral morphine consumption in the first 24h (MD = -6.93 mg; 95% CI -13.60 to -0.25; p = 0.04) compared with the FI group. However, no differences were found between the two techniques regarding dynamic and static pain scores at 6 h or 24 h post-surgery, or in the time to the first analgesic rescue after surgery. Conclusion: The findings suggest that PENG block reduced opioid consumption in the first 24 h after surgery and reduced pain scores at rest at 12 h post-surgery. Further research is needed to fully understand the effects of the PENG block and its potential benefits compared to FI block.

Ultrasound Guided Fascia Iliaca Compartment Block Using Either Bupivacaine Or Bupivacaine With Dexmedetomidine For Postoperative Analgesia In Patients With Femur Fractures.

Background: Femur fractures are extremely painful due to the lowest pain threshold of the periosteum among the deep somatic structures. Perioperative Fascia Iliaca Compartment Block (FICB), when administered using a local anesthetic agent, bupivacaine, can reduce morbidity by providing satisfactory pain relief. Dexmedetomidine, an alpha-2 agonist, is known to prolong the local anesthetic effects without causing any significant side effects. We compared analgesic duration of ultrasound guided FICB with bupivacaine alone and bupivacaine with dexmedetomidine for postoperative analgesia. A prospective, randomized, double blinded study was conducted on 50 patientsMaterials And Method: aged 18 to 65 years undergoing femur fracture surgeries. Patients were divided into 2 groups of 25 each. Both groups received USG guided FICB. Group A received 28 ml 0.25% bupivacaine and 2 ml normal saline (NS). Group B received 28 ml 0.25% bupivacaine and 30 mcg dexmedetomidine in NS. Pain scores were assessed every 5 minutes until 15 minutes post FICB, during positioning for subarachnoid block and every 2 hours until 24 hours post-operatively. Total duration of analgesia, cumulative analgesia requested in 24 hours, Ramsay sedation and patient satisfaction scores were recorded. Results: The mean duration of analgesia in Group A was 419.4 ± 115.35 minutes (95%CI: 374.2 – 464.6) and in Group B was 656.6 ± 137.99 minutes (95%CI: 602.5 –710.7), p <0.001. Mean VAS score during positioning for SAB in Group A was 1.60 ± 0.50 and in Group B was 0.96 ± 0.68. USG guided FICB with dexmedetomidine is superior inConclusion: providing prolonged post-operative analgesia in comparison to bupivacaine alone

Dacryocystectomy: A fibrin glue-assisted subfascial excision

This article describes a technique of dacryocystectomy involving dissection within the subfascial plane, in which the lacrimal sac fascia is preserved and the orbital fat remains undisturbed. The lacrimal sac cavity was directly injected with Tisseel fibrin glue mixed with trypan blue. This led to sac distension and facilitated its separation from surrounding periosteal and fascial attachments. Staining the lacrimal sac epithelium improved definition of the mucosal lining. Transverse sections of the lacrimal sac specimen were histologically analyzed, which confirmed that dissection was completed within a subfascial plane. The technique herein described facilitates en bloc excision of the lacrimal sac without breaching the fascial plane that separates the sac from orbital fat.

(In)tensões em fluxo no corpo vivo / (In)tensions influx in the living body / (In)tensiones que fluyen en el cuerpo vivo

Este artigo traz reflexões sobre o sistema fascial na aproximação com os estudos somáticos e a Educação Física. Deste escopo, apresenta-se um caminho de sensibilização que pretende dar visibilidade para a perspectiva facial na orientação do trabalho corporal. Tal caminho chama a atenção para o fato de que somos seres de natureza viscoelástica, e, enquanto tais, embora sejamos amplamente sujeitos à lógica biomecânica newtoniana, pulsamos nas entrelinhas dessa leitura calculista de compreensão da vida, de modo a afirmar a linguagem das (in)tensões, de onde se evidencia o sistema fascial. Neste sentido, as fáscias oferecem possibilidades interessantes para ingressarmos a fundo na linguagem e na compreensão do movimento humano, ao oportunizar a composição de visões mais amplas e conectivas acerca do corpo, que se apresentam à percepção como um universo fluído (aquoso), no qual irrompem as energias sutis, no ebulir das sensações, das emoções e dos sentimentos que preenchem de sentidos a experiência de movimento.

This article brings reflections about the fascial system in the approach to somatic studies and Physical Education. From this scope, a path of awarenessis presented, which aims to give visibility to the fascial perspective on bodywork orientation. This path draws our attention to the fact that we, as human beings, have viscoelastic properties, and, as such, although we are widely prone to the Newtonian biomechanical logic, we pulse in between the lines from its calculating classical literature of life comprehension, in such a way as to reaffirm the language of (in)tensions. In this sense, the qualification of the Physical Education intervention, which involves the need to seek greater attention and awareness of this (in)tensions flow, without which we do not ascend into the language and comprehension of the human movement, by providing the opportunity for the composition of broader and more connective views about the body, that are presented to the perception as a fluid (watery) universe, in which erupt the subtle energies, in the ebullition of sensations, emotions and feelings that fill of meaning the movement experience.

Feasibility study of immediate breast reconstruction with fusion fascia combined with implants / 中华肿瘤杂志

Objective: To investigate the oncologic and surgical safety of the fused fascia method for immediate breast reconstruction with implants. Methods: The clinical data of 343 patients with immediate breast reconstruction with implants in Tianjin Medical University Cancer Hospital from 2014-2017 were retrospectively analyzed to compare the 5-year local recurrence-free survival, 5-year disease-free survival and 5-year overall survival of patients with breast reconstruction by fusion fascia and other methods, and to analyze the complication incidences of implant removal between different implant groups. Results: Of the 343 patients with breast reconstruction, 95 were in the fused fascia group (fascia group) and 248 were in the non-fascia group (25 in the bovine pericardial patch group and 223 in the muscle flap group). At a median follow-up of 49 months, the differences in 5-year local recurrence-free survival (90.1% and 94.9%, respectively), 5-year disease-free survival (89.2% and 87.6%, respectively), and 5-year overall survival (95.2% and 95.1%, respectively) between patients in the fascial and non-fascial groups were not statistically significant (P>0.05). The complication incidence of implant removal was 24.0% (6/25) in the patch group and 2.1% (2/95) and 2.2% (5/223) in the fascia and muscle flap groups, respectively. Conclusion: Immediate breast reconstruction with fused fascial combined with implant is safe and feasible, less invasive than muscle flaps, more economical and with fewer complications than patches.

Use of the serratus anterior fascia in immediate implant-based breast reconstruction

Using the serratus anterior fascia may be a safe and effective option to recreate the lateral breast profile during subpectoral breast reconstruction, with minimal functional impact on the donor site. However, the literature is scarce when it comes to studies on this fascia flap in implant-based reconstruction. This article aimed to review the use of the serratus anterior fascia in immediate implant-based breast reconstruction, searching the electronic databases PubMed, Embase, Lilacs, and SciELO. The search was carried out by combining the following keywords: 'breast reconstruction' and 'serratus anterior fascia'. In the Pubmed and Embase databases, the search yielded a total of 12 and 15 articles, respectively, of which seven were selected according to the scope of this article. We found no studies on serratus anterior fascia and breast reconstruction in the Lilacs and SciELO databases. All works have results favorable for the use of the serratus anterior fascia flap and agree that this technique can be considered in the algorithm for the coverage of the inferolateral portion during subpectoral breast reconstruction

Clinical analysis of hypospadias repair with free tube graft urethroplasty / 现代泌尿外科杂志

As an optional method for the treatment of hypospadias, free tube graft urethroplasty has been applied in some centers in recent years. It has the advantages of convenient urethra materials, high freedom of surgery, and satisfactory urine flow and appearance, but there are fewer reported cases and many complications. Therefore, it is recommended to be used cautiously. This paper summarizes the experience of 497 cases of free surgical surgery based on Buck fascia reconstruction, including key points such as full correction of penile lower curvature, no tension-free urethra, long-inclined plane anastomosis, and reliable coverage enhancement.

Comparison of analgesic efficacy and postoperative recovery between multi-point and single-point fascia iliaca compartment block in patients with hip fracture: a randomized controlled trial / 中华全科医师杂志

Objective:To compare the analgesic effect and postoperative recovery between multi-point and single-point ultrasound-guided fascia iliaca compartment block (FCIB) in elderly patients with hip fracture.Methods:From June 2019 to April 2020, 96 patients aged (71.1±5.4) years undergoing elective surgery for hip fracture in Renji Hospital were randomly assigned in multi-point block group or single-point block group, and the multi-point or single-point ultrasound-guided FCIB was performed for the two groups, respectively. The primary outcomes were the success rate for block of femoral nerve, lateral femoral cutaneous nerve and obturator nerve, and the 24 hours postoperative pain visual analog scale (VAS) score at rest and passive movement. The secondary outcomes were the onset time of sensory blocks of the above three nerves, complications of FICB, the satisfaction score of pain control during 48 hours after surgery and postoperative recovery of patients.Results:The success rate for block of lateral femoral cutaneous nerve in multi-point block group was 97.9% (47/48), which was significantly higher than that in single-point block group (83.3%(40/48)) ( P=0.031). The success rate for block of obturator nerve in multi-point block group was 95.8% (46/48), which was significantly higher than that in single-point block group which was 81.3% (39/48) ( P=0.025). The success rate of femoral nerve block in both groups was 97.9% (47/48) ( P=1.000). The 24 hours postoperative VAS scores at rest and passive movement in the multi-point block group were significantly lower than those in the single-point block group ( P<0.05). The onset time for block of lateral femoral cutaneous nerve and obturator nerve in multi-point block group was shorter than that in single-point block group ( P=0.025 and P<0.01). There was no significant difference in the onset time for block of femoral nerve between the two groups ( P=0.343). The satisfaction score of patients at 48 hours after surgery in multipoint block group was higher than that in single point block group ( P=0.024). The length of hospital stay in the multi-point block group was shorter than that in the single-point block group ( P=0.042), the proportion of intravenous analgesic drugs used after surgery was lower than that in the single-point block group ( P=0.041), and the complication rate within 30 days after surgery was also lower than that in the single point block group ( P=0.026). Conclusion:Compared with single-point block, ultrasound-guided multi-point block in iliac fascia space has advantages of increasing analgesic efficacy and promoting postoperative recovery in elderly patients with hip fracture.

Optimization strategies of anesthesia for modified radical mastectomy: pecto-intercostal fascial block-pectoral nerve block type Ⅱ-general anesthesia / 中华麻醉学杂志

Objective:To evaluate the efficacy of pecto-intercostal fascial block (PIFB)-pectoral nerve block type Ⅱ (PECS Ⅱ block)-general anesthesia for modified radical mastectomy.Methods:Forty-six patients, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, aged 40-65 yr, scheduled for elective modified radical mastectomy, were divided into 2 groups ( n=23 each) using a random number table method: PECS Ⅱ block-general anesthesia group (group P+ G) and PIFB-PECS Ⅱ block-general anesthesia group (group P+ P+ G). The patients received ultrasound-guided PECS Ⅱ block (P+ G group) or PIFB combined with PECS Ⅱ block (P+ P+ G group) in the pre-anesthesia room. Then the patients were admitted to the operating room, and midazolam, propofol, sufentanil and cisatracurium were used for anesthesia induction, and sevoflurane, remifentanil and cisatracurium were used for anesthesia maintenance. The intraoperative consumption of remifentanil, emergence time and extubation time were recorded. Flurbiprofen axetil 50 mg was intravenously injected as rescue analgesic after operation, and visual analog scale score was maintained ≤3 at rest. The requirement for rescue analgesia and occurrence of nausea and vomiting within 24 h after operation were recorded. Results:Compared with group P+ G, the intraoperative consumption of remifentanil was significantly decreased, the emergence time and extubation time were shortened, the rate of rescue analgesia within 24 h after operation was decreased, the time of first rescue analgesia was prolonged ( P<0.05), and no significant change was found in the incidence of nausea and vomiting in group P+ P+ G ( P>0.05). Conclusions:Compared with PECS Ⅱ block-general anesthesia, PIFB-PECS Ⅱ block-general anesthesia can reduce the amount of intraoperative opioids, inhibit postoperative hyperalgesia and promote early postoperative recovery when used for modified radical mastectomy.

Objective:To systematically compare the analgesic efficacy of pericapsular nerve group (PENG) block and fascia iliaca compartment block (FICB) after hip fracture surgery.Methods:Databases including Pubmed, Embase, Cochrane, CNKI, Wanfang and VIP were searched for randomized controlled trials involving comparison of the analgesic efficacy of PENG block and FICB after hip fracture surgery from inception to August 2022. The primary outcome was the postoperative pain score, and the secondary outcome was the amount of postoperative analgesics and incidence of postoperative adverse reactions. The data were analyzed using Revman 5.4 software.Results:Eight studies were included ( n=374), and the pain score at rest 30 min after block was significantly lower in PENG group than in FICB group ( MD=-0.35, 95% CI -0.60--0.11, I2=14%, P<0.05). There was no statistically significant difference between PENG group and FICB group in pain scores at rest and during activity at 6, 12, 24 and 48 h after operation ( P>0.05). Compared with FICB group, the amount of analgesics used was significantly reduced at 24 and 48 h after operation in PENG group ( MD=-9.10, 95% CI -19.11-0.91, I2=95%, P<0.05). There was no statistically significant difference in the incidence of adverse reactions after operation between the two groups ( P>0.05). Conclusions:PENG block provides better efficacy when used for analgesia following hip fracture than FICB.

Analysis on effective concentrations and adverse reactions of Ropivacaine in the modified fascial iliac compartment block for pain relief after total knee arthroplasty in elderly patients / 中华老年医学杂志

Objective:To identify the effective concentrations of Ropivacaine in the modified fascial iliac compartment block(FICB)that would not affect the movement of the affected limb but would offer effective pain relief after total knee arthroplasty(TKA)in elderly patients.In addition, adverse reactions within 24 hours of FICB were examined.Methods:This study was a prospective, single-arm sequential trial.Forty-five elderly patients treated with TKA at the First Affiliated Hospital of Soochow University between September 2021 and March 2022 were selected, with an American Society of Anesthesiologists(ASA)score of Ⅰ or Ⅱ.All patients were given ultrasound-guided FICB on the surgical side under general anesthesia and 10 minutes before the operation, and the injection volume was 30 ml.According to preliminary experiments and relevant literature, the initial concentration of Ropivacaine was 0.1%, and the concentration for the next patient was determined using a modified Dixon sequential method.If the quadriceps femoris muscle strength score of the first patient was ≥4, there was no resting pain[visual analogue scale(VAS)score ≤1], and the VAS score during activity was ≤3, the concentration for the next patient would be reduced.Conversely, the concentration would be increased.The Ropivacaine concentration was increased or decreased by 0.01% each time and the trial would be stopped after 12 reentries.The median effective concentration(ED50), 95% effective concentration(ED95)and corresponding 95% confidence interval(CI)of ropivacaine were calculated using the probit model.Meanwhile, adverse reactions within 24 hours of FICB were monitored.Results:Of 43 elderly patients who completed the trial, the intervention was effective in 23 and ineffective in 20.While ensuring that postoperative limb movement in elderly patients was not affected, a single injection of 30 ml ropivacaine through FICB was able to effectively inhibit postoperative pain, and the ED50 and ED95 of ropivacaine were 0.072%(95% CI: 0.065%-0.078%)and 0.093%(95% CI: 0.084%-0.124%), respectively.Within 24 hours of FICB, 2 patients had lower limb weakness and could not get out of bed and walk, and 5 patients had severe pain and needed additional analgesics.No other adverse reactions were found. Conclusions:The effective ED50 and ED95 of Ropivacaine for postoperative pain relief in elderly patients after TKA are 0.072% and 0.093%, respectively.And the incidence of adverse reactions is low.

Fascia lata autograft bridging combined with long head of biceps tendon transposition for irreparable massive rotator cuff tear / 中华骨科杂志

Objective:To investigate the early clinical effect of fascia lata autograft bridging combined with the long head of biceps tendon transposition for treatment of irreparable massive rotator cuff tear.Methods:All of 31 cases of massive irreparable rotator cuff tear treated in our hospital from March 2016 to March 2020 were analyzed retrospectively. Among them, 17 cases (10 males, 7 females) were repaired with fascia lata autograft bridging under arthroscopy (patch group), the average age was 61.47±6.63 (ranging from 51 to 72) and 14 cases (4 males, 10 females) were repaired with fascia lata autograft bridging combined with the long head of biceps tendon transposition (combined group), the average age was 62.57±6.11 (ranging from 53 to 71). The operation time, intraoperative blood loss, postoperative complications, visual analogue scale (VAS) of pain before operation, at 1 week and 12 months after operation, Constant-Murley score of shoulder joint and American Association of shoulder and elbow Surgeons (ASES) score before operation, at 6 months and 12 months after operation were compared between the two groups. The outcome of rotator cuff healing was evaluated by MRI 1 year after operation.Results:All patients were followed up for 12-27 months (mean 18.33 ±6.8 months). There was no perioperative complication, and there was no significant difference in operation time between the two groups ( P>0.05) . The VAS score in the patch group was significantly higher than the combined group 1 week after operation ( t=2.09, P=0.048) , and there was no significant difference in VAS score 12 months after operation between the two groups. Constant-Murley score and ASES score in the combined group were significantly higher than the patch group at 6 months after operation ( t=5.23, P<0.001; t=4.45, P<0.001) , and there was no significant difference in Constant score and ASES score between the two groups at 12 months after operation. Constant score and ASES score in the two groups were significantly higher than those before operation. One year after operation, the MRI of the affected shoulder showed that the incidence of autograft patch thinning (Sugaya grade III) was 52.94%, the autograft patch structure failure rate (Sugaya grade IV and V) was 17.65% in the patch group, the autograft patch thinning rate (Sugaya grade III) was 35.71%, and the structural failure rate (Sugaya grade IV and V) was 7.14% in the combined group. The difference was statistically significant (χ 2=7.12, P=0.028) . Conclusion:Fascia lata autograft patch bridging combined with long head of biceps tendon transposition technique for treatment of irreparable massive rotator cuff tear has less pain 1 week after operation and better recovery of shoulder function half a year after operation. MRI showed better patch healing 1 year after operation.

Risk factors for residual pain after percutaneous kyphoplasty for osteoporotic vertebral fractures / 中华创伤骨科杂志

Objective:To analyze the risk factors for residual pain after percutaneous kyphoplasty (PKP) for osteoporotic vertebral fractures (OVF).Methods:Retrospectively analyzed were the patients with OVC who had been treated at Department of Orthopaedic Surgery, The First Affiliated Hospital of Soochow University by single level PKP from January 2020 to December 2021. They were 40 men and 181 women, with an age of (69.6±8.2) years. By the pain score of visual analogue scale (VAS) on the postoperative day 3, they were assigned into 2 groups: a residual pain group (VAS≥4) and a control group (VAS<4). The general demographics, radiographic and surgical related data of the 2 groups were analyzed by single factor analysis, including their gender, age, bone mineral density, body mass index, glucocorticoid usage, follow-up time, duration of symptoms, fracture location, severity of fracture compression, intravertebral cleft, middle column involvement, thoracolumbar fascia injury, anesthesia method, puncture method, volume of bone cement injected, cement-endplates contact, pattern of cement distribution, cement leakage, vertebral height restoration, preoperative cobb angle and correction of cobb angle. The P<0.1 factors screened were further analyzed by the multivariate logistic regression to determine the final variables. Results:In the present study, 19 patients were assigned into the residual pain group and 202 patients the control group. The univariate analysis showed that body mass index ( P=0.059), intravertebral cleft ( P=0.049) and thoracolumbar fascia injury ( P< 0.001) increased the risk for residual pain. The multivariate logistic regression analysis showed that thora-columbar fascia injury was an independent risk factor for residual pain ( OR=6.127, 95% CI: 2.240 to 16.755, P<0.001). Conclusion:Thoracolumbar fascia injury is an independent risk factor for residual pain after PKP for OVF.

Treatment of Irreparable Rotator Cuff Tears: Superior Capsular Reconstruction with Fascia Lata Allograft / Tratamento das rupturas irreparáveis do manguito rotador: Reconstrução capsular superior com aloenxerto de fáscia lata

Abstract Objective The objective of the present study was to evaluate the efficacy and safety of superior capsular reconstruction (SCR) using fascia lata allograft. Methods A prospective case series of 15 patients with irreparable supraspinatus tear who underwent SCR using fascia lata allograft. The American Shoulder and Elbow Surgeons (ASES) scale at 12 months after surgery was the primary outcome. The University of California Los Angeles (UCLA), Constant-Murley, and Single Assessment Numeric Evaluation (SANE) scales, in addition to the range of motion, were secondary outcomes. Radiological parameters were also evaluated by simple radiographs and magnetic resonance imaging (MRI). Results Fifteen patients completed 12 months of postoperative follow-up. The ASES score increased from 34.0 to 73.0 (p= 0.005). The UCLA, Constant-Murley, and SANE scales also showed statistically significant differences (p= 0.001; p= 0.005; and p= 0.046). In the evaluation of range of motion, there was improvement in elevation and in external rotation (95 to 140°, p= 0.003; 30 to 60°, p= 0.007). Six patients (40%) had complete graft healing. The clinical outcomes were significantly higher in the patients who presented graft healing. Conclusions Superior capsular reconstruction using a fascia lata allograft is a safe and effective procedure in short follow-up. Level of Evidence IV; Therapeutic Study; Case Series.

Resumo Objetivo O objetivo do presente estudo foi avaliar a eficácia e a segurança da reconstrução capsular superior (RCS) com a utilização do aloenxerto de fáscia lata. Métodos Uma série de casos prospectivos de 15 pacientes com ruptura irreparável do supraespinhal foi submetida a RCS com aloenxerto de fáscia lata, sendo adotada como desfecho primário a escala American Shoulder and Elbow Surgeons (ASES, na sigla em inglês) aos 12 meses do pós-operatório. Como desfechos secundários, foram adotadas as escalas da University of California Los Angeles (UCLA, na sigla em inglês), Constant-Murley, e Single Assessment Numeric Evaluation (SANE, na sigla em inglês), além da amplitude de movimento. Os parâmetros radiológicos também foram avaliados por radiografias simples e ressonância magnética (RM). Resultados Quinze pacientes completaram 12 meses de acompanhamento pós-operatório. O escore ASES aumentou de 34,0 para 73,0 (p= 0,005). As escalas UCLA, Constant-Murley e SANE também apresentaram diferenças estatisticamente significativas (p= 0,001; p= 0,005; e p= 0,046). Na avaliação da amplitude de movimento, houve melhora na elevação e rotação externa (95 a 140°, p= 0,003; 30 a 60°, p= 0,007). Seis pacientes (40%) tiveram cicatrização completa do enxerto. Os desfechos clínicos foram significativamente maiores nos pacientes que apresentaram cicatrização do enxerto. Conclusões A RCS com aloenxerto de fáscia lata é um procedimento seguro e eficaz com um curto acompanhamento de tempo. Nível de evidência IV; Estudo Terapêutico; Série de casos.

The effect of the minimum effective volume for suprainguinal fascia iliaca block in fresh cadavers / El efecto del volumen efectivo mínimo para el bloqueo de la fascia ilíaca suprainguinal en cadáveres frescos

SUMMARY: The goal of ultrasound-guided suprainguinal fascia iliaca block (USG-SFIB) is anesthetic spread to three nerves, which are lateral femoral cutaneous nerve (LFCN), femoral nerve (FN), and obturator nerve (ON). The 90 % minimum effective volume (MEV90) for USG-SFIB is each result of studied showed the successful block and effect in various volume for block. So, Thus, the study purposes to demonstrate the efficiency of the effective volume (MEV90,62.5 ml) for USG-SFIB and confirm the staining of dye in connective tissue of nerve (nerve layer) that focused on the obturator nerve by histological examination in cadavers. The histological result showed the dye staining on the nerve layer of the ON in epineurium (100 %) and un-staining perineurium & endoneurium. Therefore, the minimal effective volume (MEV) is effective for USG-SFIB. Moreover, dye stain at the epineurium of stained obturator nerve only.

RESUMEN: El objetivo del bloqueo de la fascia ilíaca suprainguinal guiado por ecografía (USG-SFIB) es la propagación anestésica a tres nervios, cutáneo femoral lateral, femoral y obturador. El volumen efectivo mínimo del 90 % (MEV90) para USG-SFIB en cada uno de los resultados mostró el bloqueo exitoso y el efecto en varios volúmenes por bloqueo. Por lo tanto, el estudio tuvo como objetivo demostrar la eficiencia del volumen efectivo (MEV90,62.5 ml) para USG-SFIB y confirmar la tinción de tinte en el tejido conectivo del nervio, el cual se centró en el nervio obturador a través del examen histológico en cadáveres. El resultado histológico mostró tinción de colorante en el epineuro (100 %) del nervio obturador, sin embargo no hubo tinción del perineuro y endoneuro. Por lo tanto, el volumen efectivo mínimo (MEV) es efectivo para USG-SFIB.

Anatomical study of the latissimus dorsi muscle flap / Estudio anatómico del colgajo del músculo latísimo del dorso

SUMMARY: The latissimus dorsi is a broad muscle that originates from the inferior thoracic spinous processes, thoracolumbar fascia, iliac crest, and inferior ribs. It inserts on the inferior aspect of the intertubercular groove of the humerus through a thin tendon. The study was conducted on 10 cadavers (7 male and 3 female). These specimens were dissected and examined to study the gross anatomical characteristics of the latissimus dorsi muscle. The dimensions of the latissimus dorsi muscle and its surface area were measured in all the cadavers. The branching pattern of the thoracodorsal vessels was recorded. The pedicle length and caliper were measured using Vernier calipers. On the 20 dissected sides, the thoracodorsal artery was found to be one of the terminal branches of the subscapular artery that originates in the axillary region. In 19 (95 %) cases, the thoracodorsal artery terminated in a bifurcation, giving off a medial and a lateral branch. The average size of the elevated flap of the latissimus dorsi muscle was 18 cm x 36 cm. The average pedicle length was 9.5 cm (range: 5 cm-14 cm), and the average diameter at its origin was 2.5 mm (range: 1.5 mm-3.5 mm). The average diameter of the vena comitans was 3.3 mm. The current study focuses on the anatomical features of the latissimus dorsi muscle and its blood supply to increase the success rate of operations in clinical practice.

RESUMEN: El músculo latísimo del dorso se origina en los procesos espinosos de las vértebras torácicas inferiores, la fascia toracolumbar, la cresta ilíaca y las costillas inferiores y se inserta en el surco intertubercular del húmero a través de un delgado tendón. El estudio se realizó en 10 cadáveres (7 mujeres y 3 hombres). Estos especímenes fueron disecados y examinados para estudiar las características anatómicas macroscópicas del músculo latísimo del dorso. En todos los cadáveres se midieron las dimensiones del músculo y su superficie. Se registró el patrón de ramificación de los vasos toracodorsales. La longitud del pedículo y el calibre se midieron con paquímetro Vernier. En los veinte lados disecados, se encontró que la arteria toracodorsal era una de las ramas terminales de la arteria subescapular que se originaba en la región axilar. En 19 (95 %) casos, la arteria toracodorsal terminaba bifurcándose en dos ramas, una rama medial y otra lateral. El tamaño promedio del colgajo elevado del músculo latísimo del dorso era de 18 cm x 36 cm. La longitud promedio del pedículo era de 9,5 cm (rango: 5 cm-14 cm), y el diámetro promedio en su origen era de 2,5 mm (rango: 1,5 mm-3,5 mm). El diámetro medio de la vena comitans era de 3,3 mm. El estudio actual se centra en las características anatómicas del músculo latísimo del dorso y su irrigación para aumentar la tasa de éxito de las operaciones en la práctica clínica.
