Functional Shoulder Evaluation after Osteosynthesis of Greater Tuberosity Fracture: Is There any Influence of Glenohumeral Dislocation? / Avaliação funcional do ombro após osteossíntese da fratura da tuberosidade maior: Há influência da luxação glenoumeral?

Abstract Objective To evaluate the postoperative functional and radiographic outcomes of the shoulder of patients submitted to transosseous suturing of a greater tuberosity fracture (GTF) through an anterolateral route and the influence of the glenohumeral dislocation on these outcomes. Methods We conducted a retrospective study and functional assessment using the Constant-Murley score. The distance between the greater tuberosity and the joint surface of the proximal humerus (in true anteroposterior radiographs) after the union was calculated. We used the Fisher exact test for the categorical independent variables, and the Student t or Mann-Whitney test for the non-categorical variables. Results In total, 26 patients met the inclusion criteria, and 38% of the sample presented an association between glenohumeral dislocation and GTF. The mean Constant-Murley score was of 82.5 + 8.02 points. The presence of an associated dislocation did not alter the functional outcome. The mean distance between the greater tuberosity of the humerus and the joint surface of the humeral head after the union was of 9 + 4.3 mm below the articular line of the humeral head. The dislocation led to a lower level of reduction, but this did not influence the Constant-Murley score. Conclusion The cases of GTF submitted to surgical treatment with transosseous sutures had good functional outcomes. The presence of dislocation made the anatomical reduction of the greater tuberosity difficult. However, it did not influence the Constant-Murley score.

Resumo Objetivo Avaliar os resultados funcional e radiográfico pós-operatórios do ombro, em pacientes submetidos a sutura transóssea de fratura da tuberosidade maior (FTM) por acesso anterolateral, e a influência da luxação glenoumeral nesses resultados. Métodos Realizou-se estudo retrospectivo e avaliação funcional (pela escala de Constant-Murley). Calculou-se a distância entre a tuberosidade maior e a superfície articular do úmero proximal (por meio de radiografia em incidência anteroposterior verdadeira) após a consolidação. Usou-se o teste Exato de Fisher para as variáveis independentes categóricas, e os testes tde Student ou de Mann-Whitney para as não categóricas. Resultados Ao todo, 26 pacientes preencheram os critérios de inclusão. A associação de luxação glenoumeral com FTM foi observada em 38% da amostra. A média da pontuação na escala de Constant-Murley foi de 82,5 + 8,02. A presença de luxação associada não alterou o resultado funcional. A distância média da consolidação da tuberosidade maior do úmero em relação à superfície articular da cabeça umeral foi de 9 + 4,3 mm abaixo da linha articular da cabeça umeral. Pacientes com luxação associada evoluíram com redução menor, mas isso não influenciou na pontuação na escala de Constant-Murley. Conclusão As FTMs submetidas ao tratamento cirúrgico com sutura transóssea evoluíram com bom resultado funcional. A presença de luxação dificultou a redução anatômica da tuberosidade maior. Entretanto, isso não influenciou na pontuação na escala de Constant-Murley.

Assessing Endoscopic Suture Performance of Gynecology and Obstetrics Residents Following Methodic Training / Avaliando a performance em sutura endoscópica de residentes de ginecologia e obstetrícia após treinamento metódico

Abstract Objective To evaluate the performance of residents in gynecology and obstetrics before and after practicing laparoscopic sutures, to establish when the training shows the best results, in addition to comparing whether being in different years of residency influences this progression. Methods A prospective cohort study involving 32 medical residents evaluated with a pretest to establish their previous knowledge in laparoscopic suture. This test consisted of knotting two wires, one made of polypropylene and the other of polyglactin, with a blocking sequence of five semi-knots. We set a 30-minute limit to complete the task. Then, the residents held four training meetings, focusing on suture, Gladiator rule, knot, and symmetries, in addition to executing blocking sequences. A second test to establish progress was performed. Results Regarding the time spent to make the stiches using polyglactin wire, a statistically significant time improvement (p< 0.01) was observed, with a 10.67-minute pretraining median (mean 12.24 minutes) and a 2.53-minute posttraining median (mean 3.25 minutes). Regarding the stitches with polypropylene wire, a statistically significant time improvement (p< 0.05) was also observed, with a 9.38-minute pretraining median (mean 15.43 minutes) and a 3.65-minute posttraining median (mean 4.54 minutes). A total of 64.2% of the residents had been able to make the knot with polypropylene previously. One hundred percent were able to complete the task in the posttest. Conclusion Model training using the Gladiator rule for laparoscopic suture improves the knotting time with statistically similar performance, regardless of the year of residency, after systematic training.

Rinoplastia en nariz mestiza, un desafío quirúrgico / Rhinoplasty in mestizo nose, a surgical challenge

Las características anatómicas de pacientes con nariz mestiza, generalmente, incluyen una nariz aparentemente grande, un dorso convexo con radix bajo y una base nasal ancha. La longitud de la columela y punta nasal se ve disminuida debido a que los cartílagos alares son cortos, débiles y delgados, proporcionando un soporte estructural insuficiente, mala definición y proyección de la punta nasal. La principal dificultad al manejar este tipo de narices es un marco osteocartilaginoso mal estructurado y débil. En los últimos años se han desarrollado técnicas quirúrgicas para mejorar los resultados estéticos y funcionales de la rinoplastía en estos pacientes. Se realizó una revisión exhaustiva de la literatura describiendo las técnicas quirúrgicas utilizadas en este tipo de nariz.

The anatomical characteristics of patients with mestizo nose usually include an apparently large nose, a convex dorsum with a deep radix, and a wide nasal base. The length of the nasal columella and tip is decreased because the alar cartilages are short, weak and thin, providing insufficient structural support, poor definition and nasal tip projection. The main difficulty in managing this type of noses is a poorly structured and weak osteocartilaginous framework. In recent years, surgical techniques have been developed to improve the aesthetic and functional results of rhinoplasty in these patients. A comprehensive literature review was conducted describing the surgical techniques used in this type of nose.

Arthroscopic fixation of chronic bicruciate tibial avulsion fractures: A case report / 中华创伤杂志(英文版)

A cruciate ligament avulsion is a much less common form of injury than a cruciate ligament tear. Simultaneous tibial avulsion fractures of both cruciate ligaments occur even more rarely. Over the last decades, many studies have described arthroscopic fixation of acute cruciate tibial avulsion fractures, but arthroscopic treatment in a late presenting patient has not been reported in the literature. This case report presents a 32-year-old female with a chronic tibial avulsion fracture of both anterior cruciate ligament and posterior cruciate ligament. Simultaneous fixation of both fractures was performed arthroscopically at week four post-injury. At one year of follow-up, the patient had demonstrated full knee range of motion and stable knee with no complaints, and achieved excellent clinical outcomes. Radiographs showed union of both fractures, and the patient had resumed high-impact exercises.

Effectiveness of arthroscopic binding fixation using suture through single bone tunnel for posterior cruciate ligament tibial insertion fracture in adults / 中国修复重建外科杂志

OBJECTIVE@#To explore the effectiveness of arthroscopic binding fixation using suture through single bone tunnel for posterior cruciate ligament (PCL) tibial insertion fractures in adults.@*METHODS@#Between October 2019 and October 2021, 16 patients with PCL tibial insertion fractures were treated with arthroscopic binding fixation using suture through single bone tunnel. There were 11 males and 5 females with an average age of 41.1 years (range, 26-58 years). The fractures were caused by traffic accident in 12 cases and sports in 4 cases. The time from injury to operation ranged from 2 to 10 days with an average of 6.0 days. The fractures were classified as Meyers-McKeever type Ⅱ in 4 cases and type Ⅲ in 9 cases, and Zaricznyi type Ⅳ in 3 cases. There were 2 cases of grade Ⅰ, 7 cases of grade Ⅱ, and 7 cases of grade Ⅲ in the posterior drawer test. There were 3 cases combined with lateral collateral ligament injury and 2 cases with meniscus injury. The visual analogue scale (VAS) score, Lysholm score, International Knee Documentation Committee (IKDC) score, and knee range of motion were used to evaluate knee joint function. The posterior drawer test and knee stability tester (Kneelax 3) were used to evaluate knee joint stability. The X-ray films were used to evaluate fracture reduction and healing.@*RESULTS@#All incisions healed by first intention after operation. There was no incision infection, popliteal neurovascular injury, or deep venous thrombosis of lower limbs. All patients were followed up 6-12 months, with an average of 10 months. X-ray films at 6 months after operation showed the fractures obtained bone union. There were 11 cases of grade 0, 4 cases of gradeⅠ, and 1 case of grade Ⅱin posterior drawer test, showing significant difference when compared with preoperative results ( Z=23.167, P<0.001). The VAS score, Lysholm score, IKDC score, knee range of motion, and the results of Kneelax3 examination all significantly improved when compared with preoperative results ( P<0.05).@*CONCLUSION@#For adult patients with PCL tibial insertion fractures, the arthroscopic binding fixation using suture through single bone tunnel has the advantages of minimal trauma, good fracture reduction, reliable fixation, and fewer complications. The patient's knee joint function recovers well.

Among them, 14 patients were fixed with simple absorbable screw (group A), and 12 patients were fixed with absorbable screw combined with suture anchors (group B). All patients were confirmed by X-ray film, CT, or MRI preoperatively, and got positive results in preoperative posterior drawer tests. There was no significant difference in gender, age, side of affected limb, time from injury to operation, comorbidities, and preoperative Meyers & McKeever classification, Lysholm score, and International Knee Documentation Committee (IKDC) score between the two groups ( P>0.05). The operation time and postoperative complications were recorded and compared between the two groups. At last follow-up, Lysholm score and IKDC score were used to evaluate the improvement of knee function.@*RESULTS@#There was no significant difference in operation time between the two groups ( P>0.05). All incisions healed by first intention, and no complication such as vascular and nerve injury or venous thrombosis occurred. All 26 patients were followed up 9-89 months, with an average of 55.3 months. The follow-up time of group A and group B was (55.7±23.2) and (56.8±29.3) months, respectively, with no significant difference ( t=-0.106, P=0.916). Radiographs showed bone healing in both groups at 3 months after operation, and no complication such as infection and traumatic arthritis occurred. At last follow-up, the posterior drawer test was negative in both groups, and the Lysholm score and IKDC score significantly improved when compared with the pre-operative values ( P<0.05). However, there was no significant difference in the improvement value between the two groups ( P>0.05).@*CONCLUSION@#For PCL avulsion fracture at tibial insertion of the knee joint, the open reduction and absorbable screw combined with suture anchor fixation can achieve reliable fracture reduction and fixation, which is conducive to the early rehabilitation and functional exercise, and the postoperative functional recovery of the knee joint is satisfactory.

Microinvasive Meniscal Suture with Disposable Needle / Sutura meniscal microinvasiva com agulha descartável

Abstract The first meniscal suture was performed in 1885 and took about a century to become popular. Currently, all-inside meniscal repair devices are widely used. However, this technique presents the disadvantage of being a method dependent on specific devices, presenting a higher cost than other techniques. This high cost limits the use of such a technique in many locations. The objective of the present technical note is to describe a microinvasive meniscal suture technique as a modification of the all-inside technique, using a disposable 40 x 12 mm procedure needle. The authors believe that the proposed modification to the technique can make it more popular, enabling the use of the microinvasive technique in places with limited resources.

Resumo A primeira sutura meniscal foi realizada em 1885 e levou cerca de um século para tornar-se popular. Atualmente, os dispositivos de reparo meniscal all-inside são amplamente utilizados. Contudo, esta técnica apresenta a desvantagem de ser um método dependente de dispositivos específicos, apresentando um custo superior aos de outras técnicas. Este valor elevado limita o uso de tal técnica em muitos locais. O objetivo da presente nota técnica é descrever uma técnica de sutura meniscal microinvasiva, como uma modificação da técnica all-inside, utilizando uma agulha descartável de procedimento de 40 x 12 mm. Os autores acreditam que a modificação proposta para a técnica pode torná-la mais popular, possibilitando o uso da técnica microinvasiva em locais com recursos limitados.

Uso de vasopresina y suturas transfixivas para el tratamiento quirúrgico de la gestación ectópica intersticial / Use of vasopressin and transfixive sutures for the surgical treatment of interstitial ectopic gestation

Resumen La gestación cornual, también conocida como intersticial, es una gestación ectópica infrecuente que ocurre en 1/2500 a 1/5000 de los embarazos cuando el embrión implanta en el trayecto intramiometrial de la porción proximal de la trompa. Puede debutar como shock hipovolémico en un 25% de los casos, conllevando una mortalidad de hasta un 2,5%. Mediante ecografía se encuentra un saco gestacional excéntrico y rodeado por una fina capa de miometrio. El tratamiento, en la mayoría de los casos, es quirúrgico, y el control de la hemostasia supone todo un reto. Se presentan dos casos clínicos de mujeres con diagnóstico de gestación intersticial en quienes se realizó exéresis por laparoscopia tras inyección de vasopresina, permitiendo así controlar el sangrado. En una de las pacientes se practicaron también puntos transfixivos transitorios en la arteria uterina y el ligamento útero-ovárico.

Abstract Cornual gestation, also known as interstitial, is a rare ectopic gestation that occurs in 1/2500 to 1/5000 of pregnancies when the embryo implants in the intramyometrial tract of the proximal tube. It can debut as hypovolemic shock in 25% of cases, leading to a mortality rate of up to 2.5%. Using ultrasound, we will find an eccentric gestational sac surrounded by a thin layer of myometrium. Treatment, in most cases, is surgical and control of hemostasis is a challenge. Two clinical cases are presented of women with a diagnosis of interstitial pregnancy in whom transient transfixive sutures were performed at the level of the uterine artery and uterine-ovarian ligament and injection of vasopressin prior to laparoscopic exeresis, thus allowing the bleeding to be controlled.

Microsurgical arterial anastomosis in young and adult rats: an evolutive and comparative study

Purpose: To evaluate the caliber of an arterial micro-anastomosis in the young growing animal using a continuous suture technique. Additionally, late morphological changes and blood flows distal to the anastomosis were evaluated. Methods: Seventy-four Wistar rats were submitted to laparotomy to access the aorta for blood flow measurement. The aorta was sectioned using microsurgery technique and an end-to-end anastomosis with continuous suture. After a period of six months to one year, the anastomosis was checked. Results: Regarding the size of the aortas, comparing the pre- and postoperative values, there was an increase of 13.33% in adult animals and 25% in young animals, without any difference in the blood flows. Conclusions: The arteries of young rats show signs of growth at the site of the anastomosis performed with continuous suture.

Clinical effects of arthroscopy-assisted anterior cruciate ligament tibial eminence avulsion fracture compared with traditional open surgery:a Meta-analysis / 中国骨伤

OBJECTIVE@#To systematically evaluate the clinical efficacy of arthroscopy and traditional incision in the treatment of tibial avulsion fracture of anterior cruciate ligament (ACL).@*METHODS@#From July 2010 to July 2020, clinical comparative trial about arthroscopy and traditional incision in the treatment of ACL tibial avulsion fracture was conducted by using computer-based databases, including Embase, Pubmed, Central, Cinahl, PQDT, CNKI, Weipu, Wanfang, Cochrane Library, CBM. Literature screening and data extraction were carried out according to the inclusion and exclusion criteria, and the quality of the included literature was evaluated by improved Jadad score and Ottawa Newcastle scale (NOS). The operation time, hospital stay, fracture healing time, knee range of motion, postoperative excellent and good rate, complication rate, Lysholm score, International Knee Documentation Committee (IKDC) score and Tegner score were statistically analyzed by Review Manager 5.3 software.@*RESULTS@#Finally, 16 literatures were included, including 1 randomized controlled trial and 15 non randomized controlled trials, with a total of 822 patients (405 in arthroscopy group and 417 in traditional incision group). Meta analysis showed that the operation time [MD=-9.03, 95% CI(-14.36, -3.70), P<0.001], hospital stay [MD=-5.81, 95%CI(-9.32, -2.31), P=0.001] and fracture healing time [MD=-14.61, 95% CI(-17.93, -11.28), P<0.001] in the arthroscopy group were better than those in the traditional incision group. The incidence of complications in arthroscopy group was lower than that in traditional incision group[OR=0.15, 95%CI(0.07, 0.33), P<0.001]. The postoperative excellent and good rate[OR=4.39, 95%CI (1.96, 9.82), P<0.001], knee mobility[MD=6.78, 95%CI(2.79, 10.77), P<0.001], Lysholm score[MD=11.63, 95%CI(4.91, 18.36), P<0.001], IKDC score[MD=7.83, 95%CI(6.09, 9.57), P<0.001] and Tegner score[MD=0.60, 95%CI(0.31, 0.89), P<0.001] in the arthroscopic group were higher than those in the traditional incision group.@*CONCLUSION@#Compared with the traditional open reduction and internal fixation, arthroscopic surgery in patients with ACL tibial avulsion fracture can shorten the operation time, hospital stay and fracture healing time, reduce the incidence of postoperative complications, and obtain good postoperative knee function. It can be recommended as one of the first choice for patients with ACL tibial avulsion fracture.

Comparative analysis of pathological structure between acute closed and open Achilles tendon rupture / 中国骨伤

OBJECTIVE@#To investigate the morphological, histological and ultrastructural changes of acute closed rupture of Achilles tendon, in order to clarify the pathological basis of the injury and to explore the significance.@*METHODS@#From January 2015 to January 2019, 35 patients with acute Achilles tendon rupture who underwent the minimally invasive Achilles tendon suture technique were retrospectively analyzed. Among these patients, 12 cases in acute open Achilles tendon rupture group included 10 males and 2 females, with an average age of (35.1±9.7) years old ranging from 19 to 50, and the time from injury to operation was 2 to 8 hours with an average of(5.6±1.8);23 cases in acute closed Achilles tendon rupture group included 21 males and 2 females, with an average age of (35.5±6.6) years old ranging from 18 to 50, and the time from injury to operation was 3 to 15 hours with an average of (7.5±3.1). The gross appearance and imaging findings of the broken end of Achilles tendon tissue in the two groups were compared by naked eye observation and foot and ankle MRI at 4 to 6 hours before operation. HE staining, scanning and fluoroscopic electron microscopy, immunohistochemistry(Sirius red staining) were performed on the intraoperative Achilles tendon tissue specimens at 1 to 2 days after operation, the collagen fiber degeneration and local fat infiltration, collagen fiber shape, cell morphology and function, and the distribution of typeⅠand type Ⅲ collagen fibers in Achilles tendon were compared between the two groups.@*RESULTS@#Compared with the acute open Achilles tendon rupture group, the acute closed Achilles tendon rupture group had poor elasticity, hard texture, moderate edema, irregular shape of Achilles tendon broken end, horsetail shape, and more calcification around the broken end. HE staining results:the collagen fibers in the Achilles tendon of the acute open Achilles tendon rupture group were arranged irregularly, with hyaline degeneration and fat infiltration;The results of electron microscopy showed that collagen arranged disorderly and fibroblasts atrophied in the acute closed Achilles tendon rupture group. Immunohistochemical(Sirius staining) results:the proportion of collagenⅠin the acute open Achilles tendon rupture group and the acute closed Achilles tendon rupture group was(91.12±4.34)% and(54.71±17.78)% respectively, and the proportion of collagen Ⅲ was (8.88±4.34)% and (45.29±17.78)% respectively. The content of collagenⅠin the acute closed Achilles tendon rupture group was lower than that in the acute open Achilles tendon rupture group, and the content of collagen Ⅲ in the acute closed Achilles tendon rupture group was higher than that in the acute open Achilles tendon rupture group(P<0.05).@*CONCLUSION@#The morphology, histology and ultrastructure of the acute closed ruptured Achilles tendon are significantly altered compared with the normal Achilles tendon. The original fine and orderly spatial structure cannot be maintained, part of collagen Ⅰ is replaced by collagen Ⅲ, and the toughness and strength of the tendon tissue decreased, which may be the feature of degeneration of the Achilles tendon and an important pathological basis for closed Achilles tendon rupture.
