The Direct Tendon Suture and Paratenon Repair Technique for Acute Tendinous Mallet Finger: A Case Series.

(1) Introduction: Tendinous mallet finger is a frequent deformity that occurs after an extensor tendon injury during sports or daily life activities. Despite the existence of numerous non-operative and operative techniques to address this deformity, there is a controversy on its optimal management. In this study, we aimed to present a direct tendon suture technique using the distal interphalangeal (DIP) joint open approach for treating tendinous mallet finger injury. (2) Methods: Between 2019 and 2021, 19 patients with closed non-fracture tendinous mallet fingers underwent the direct tendon and paratenon repair technique. After skin incision, we opened the paratenon with lazy S shape incision and found the ruptured proximal and distal tendon ends. We reapproximated the tendons using a simple interrupted suture with Prolene #6/0. After that, we meticulously performed paratenon repair using PDS #6/0 for preventing readherence. Temporary trans-articular Kirschner wire fixation was used for 4 weeks. (3) Results: All patients were followed-up for 3-8 months (mean: 4.8 months). The mean final extension lag was 6.5 degrees, and the overall rate of cases with excellent and good outcomes using Crawford's criteria was 85%. (4) Conclusions: In conclusion, this surgical approach could be a reliable alternative for the treatment of tendinous mallet finger injuries.

Sutura em Polia Retificada para síntese de feridas de pele tensionadas / Rectified Pulley Suture for the synthesis of tensioned skin wounds

Introdução: A síntese de feridas de pele tensionadas é uma área que tem sido alvo de estudos para o desenvolvimento de técnicas de sutura que sejam capazes de realizar o fechamento primário dessas feridas com alívio de tensão, garantindo uma cicatrização adequada e evitando complicações como deiscência, edema, sangramento e infecção. Método: Esta pesquisa tratou-se de um estudo piloto, sendo a primeira apresentação da técnica de Sutura em Polia Retificada para síntese de feridas de pele tensionadas através do acompanhamento prospectivo, duplo-cego, de uma série de casos de 8 pacientes randomicamente admitidos no centro cirúrgico de um hospital de alta complexidade de uma cidade de médio porte. Resultados: A Sutura em Polia Retificada é uma técnica versátil e apta para lidar com feridas de pele tensionadas, uma vez que no intraoperatório conseguiu fechar por primeira intenção lesões de até 6,5 centímetros e de diferentes regiões tensionadas sem necessidade do uso de técnicas mais complexas, como retalhos, enxertos, zetaplastia e fechamento por segunda intenção. Além disso, no pós-operatório, houve redução dos escores da POSAS, indicando um processo de cicatrização satisfatório tanto para os observadores quanto para o paciente. É imprescindível mencionar, também, que o desfecho mais temido no seguimento dos pacientes com feridas tensionadas submetidos a fechamento primário - a deiscência - foi completamente evitado. Conclusão: A técnica é simples, confiável, segura e reprodutível, com curta curva de aprendizagem, de forma que a Sutura em Polia Retificada pode ser considerada como uma nova ferramenta a ser integrada ao arsenal cirúrgico.

Introduction: The synthesis of tensioned skin wounds is an area that has been the subject of studies for the development of suturing techniques that are capable of performing the primary closure of these wounds with tension relief, ensuring adequate healing, and avoiding complications such as dehiscence, edema, bleeding, and infection. Method: This research was a pilot study, being the first presentation of the Rectified Pulley Suture technique for the synthesis of tensioned skin wounds through prospective, double-blind monitoring of a series of cases of 8 patients randomly admitted to the surgical center of a high-complexity hospital in a mediumsized city. Results: Rectified Pulley Suture is a versatile technique suitable for dealing with tensioned skin wounds, since intraoperatively it was able to close, by first intention, lesions measuring up to 6.5 centimeters and in different tensioned regions without the need for the use of more extensive techniques. complex, such as flaps, grafts, Z-plasty, and secondary intention closure. Furthermore, post-operatively, there was a reduction in POSAS scores, indicating a satisfactory healing process for both observers and the patient. It is also essential to mention that the most feared outcome in the follow-up of patients with tension wounds undergoing primary closure - dehiscence - was completely avoided. Conclusion: The technique is simple, reliable, safe, and reproducible, with a short learning curve, so the Rectified Pulley Suture can be considered a new tool to be integrated into the surgical arsenal.

The mini-open procedure with a modified figure of eight for managing sacrococcygeal fracture-dislocation: A case report and literature review.

INTRODUCTION AND IMPORTANCE: A fracture associated with an anteriorly displaced fragment may induce soft tissue disintegration. However, this might be avoided by maintaining the stability of the sacrococcygeal bone. Fixation by using less invasive modalities is needed to improve the outcome. CASE PRESENTATION: A 37-year-old female came with tailbone pain, which lasted around one month. There was a history of falling in a sitting position a month before hospital admission. Tenderness was positive while palpating the perineal site. A radiography examination shows a fracture in the sacrococcygeal segment with anterior dislocation. The patient was diagnosed with a sacrococcygeal fracture and anterior dislocation. CLINICAL DISCUSSION: We performed a mini-open procedure using a modified figure-of-eight technique to reconnect the sacrococcygeal bone. Suturing was performed through the skin in the painful area, and then the bone at the injured site was reduced. As an outcome, there was an improvement in the Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), and EuroQol-5 Dimensions (EQ5D) scores. CONCLUSION: A mini-open procedure with a modified figure of eight is a simple and valuable method for correcting the sacrococcygeal components.

The distance of insertion points from wound margins in interrupted and vertical mattress sutures influences the tensile load capacity: An in vitro experimental study.

AIM: To determine the tensile load capacity (TLC) and the tearing characteristics for interrupted and vertical mattress sutures with different insertion points from the wound margin, and the effect of the bite size when using vertical mattress sutures. MATERIALS AND METHODS: A total of 120 gingiva and lining mucosa samples obtained from pig jaws were divided into groups according to the suturing technique (interrupted and vertical mattress sutures), distance of the insertion points from the wound margin (margin, 1, 3, and 5 mm) and bite size (1, 3, and 5 mm). The TLC of the suture and the tearing characteristics were evaluated using a tensile tester device. RESULTS: The TLC was significantly higher for vertical mattress sutures than for interrupted sutures regardless of the distance of the insertion points from the wound margin (intergroup p < .001). This distance significantly influenced the TLC for vertical mattress sutures (p < .05) but not for interrupted sutures (p > .05). Testing the tearing characteristics revealed that no tissue tearing occurred in groups when the insertion points were more than 3 mm from the wound margin. CONCLUSION: The TLC is higher for vertical mattress sutures than for interrupted sutures, and it increases when the insertion points are farther from the wound margin.

Horizontal pharyngeal closure during total laryngectomy reduces rates of pharyngocutaneous fistula.

PURPOSE: Pharyngocutaneous fistula (PCF) is a possible complication following total laryngectomy (TL), with a mean incidence of 17%. We intended to investigate the effect of pharyngeal closure type during TL on the prevention of PCF. METHODS: We retrospectively reviewed patients that underwent TL with a horizontal pharyngeal closure over a 10-year period. The frequency of PCF clinically, dysphagia, total oral diet, postoperative dilatation of the neopharynx and voice problems were tabulated. RESULTS: Seventy-seven subjects underwent TL due to laryngeal tumor without pharyngeal extension. Of them, 45 underwent a salvage TL. PCF occurred in 1/77 subjects. The rest of the subjects (76/77) did not develop a PCF, neither in the early nor in the late postoperative phase. All subjects (15/77) that underwent implantation of a voice prosthesis were satisfied with their voice. No subject complained about dysphagia. Every subject achieved total oral diet. CONCLUSION: The horizontal pharyngeal closure is a safe pharyngeal closure technique during TL, reduces PCF rates (< 2%), results in excellent voice rehabilitation and swallowing function, and can also be used during salvage TL instead of a major pectoral flap. This type of closure should be used only in selected patients with laryngeal disease without pharyngeal extension.

Efficacy, Complications and Effects of Alcides Pereira's Sutures in the Management of Uterine Atony: A Retrospective Study.

INTRODUCTION: Uterine compressive sutures are conservative measures applied in cases of severe postpartum hemorrhage unresponsive to uterotonics. Pereira's suture was introduced in 2005 and consists of two longitudinal and three transverse non-transfixes sutures. Previous studies reported favorable results, highlighting its benefits and value. The aim of this study was to assess the efficacy, complications, and impact on fertility and future pregnancies of Pereira's suture applied in cases of uterine atony and postpartum hemorrhage. METHODS: An observational retrospective study was performed by consulting the medical records of women treated with Pereira's compressive sutures in a tertiary center between January 2013 and December 2022. We registered demographic data, pregnancy outcomes, short-term complications, and outcomes of subsequent pregnancies. RESULTS: A total of 50 women were treated with Pereira's suture. The overall success rate was 96% and no hysterectomies were performed. Women who had sutures performed during an intra-cesarean section had better outcomes than those who had an after-cesarean section. Complications were reported in 12% (n = 6) of women, with the most frequent being pelvic infection (n = 3) and abdominal pain (n = 3). Regarding fertility, all women desiring a future pregnancy (n = 5) were able to conceive, resulting in three live births. CONCLUSION: Pereira's suture is a type of suture that provides numerous advantages and should be considered when first-line medical treatment fails. When applied at an early stage, the sutures may prevent maternal morbidity. The Alcides Pereira's suture is a safe technique and appears to preserve fertility.

Management of a Large Hypervascular Apicoposterior Mediastinal Mass Using the Purse-String Suture Technique in Robotic-Assisted Thoracoscopic Surgery: A Case Report.

Complete resection of an apicoposterior mediastinal mass is essential due to the mass effect, which exerts pressure on adjacent organs. Recently, the use of minimally invasive surgery has had many advantages. In this report, we describe a case in which a large apicoposterior mediastinal hypervascular mass was managed using a purse-string suture technique during robotic-assisted thoracoscopic surgery (RATS). The patient, a 77-year-old woman, was diagnosed with a 6.2-cm apicoposterior mediastinal hypervascular solid mass originating from the branches of the right subclavian artery. The patient underwent RATS for treatment. To obtain an adequate view of the apex of the thoracic cavity, a needle aspiration was performed, followed by the application of a purse-string suture technique. This was done to reduce the size of the tumor and to prevent catastrophic events such as seeding or spillage of the cystic mass. The mass was histopathologically diagnosed as a schwannoma. The patient was discharged on the first postoperative day without experiencing any complications.

Modelo alternativo para o treinamento de técnicas de microssuturas em "patch" de pericárdio bovino / Alternative model for training microsuture techniques in bovine pericardium patches

Introdução: As técnicas microcirúrgicas caracterizam-se pela aplicação de manobras e suturas em estruturas milimétricas com o auxílio de lentes de aumento. São técnicas complexas, utilizadas em diversas especialidades médicas, que demandam grande habilidade e treinamento antes da aplicação em humanos. O objetivo é desenvolver um modelo de baixo custo e alta fidelidade, para o treinamento de técnicas de microcirurgia, utilizando um fragmento de patch de pericárdio bovino. Método: São utilizados para a confecção deste modelo segmentos remanescentes de uma placa de pericárdio bovino, previamente utilizado em reparos vasculares. O material é recortado em duas partes simétricas e suas extremidades fixadas aos campos cirúrgicos, com auxílio de clamps. A borda superior de cada uma das partes é, então, suturada à borda inferior com fio de Prolene 8-0, de maneira que cada uma forme uma estrutura tubular. Posteriormente, as extremidades tubulares livres passam pela dissecção da camada adventícia e são suturadas entre si, mimetizando uma anastomose vascular término-terminal. Resultados: Com o modelo, simulam-se os mesmos inconvenientes/ dificuldades presentes nas suturas vasculares humanas, como a delaminação de camadas, excesso da camada adventícia e risco de sutura inadvertida da parede posterior, provando sua utilidade na aquisição de habilidades microcirúrgicas básicas, sem necessidade de manipulação de tecidos humanos ou animais. A prática neste modelo pode ocorrer dentro do próprio centro cirúrgico e emprega materiais que seriam descartados. Conclusão: A utilização do pericárdio bovino para confecção de suturas milimétricas mimetiza o tecido vascular humano e é um procedimento de baixo custo, que possibilita o treinamento de habilidades microcirúrgicas.

Introduction: Microsurgical techniques are characterized by the application of maneuvers and sutures to millimetric structures with the aid of magnifying lenses. These are complex techniques, used in various medical specialties, which require great skill and training before applying them to humans. The objective is to develop a lowcost and high-fidelity model for training microsurgery techniques using a fragment of bovine pericardium patch. Method: Remaining segments of a bovine pericardium plate, previously used in vascular repairs, are used to create this model. The material is cut into two symmetrical parts, and its ends are fixed to the surgical drapes with the aid of clamps. The upper edge of each part is then sutured to the lower edge with 8-0 Prolene thread so that each one forms a tubular structure. Subsequently, the free tubular ends undergo dissection of the adventitial layer and are sutured together, mimicking an end-to-end vascular anastomosis. Results: With the model, the same inconveniences/ difficulties present in human vascular sutures are simulated, such as delamination of layers, excess of the adventitial layer, and risk of inadvertent suturing of the posterior wall, proving its usefulness in the acquisition of basic microsurgical skills, without need to manipulate human or animal tissues. Practice in this model can take place within the surgical center itself and uses materials that would otherwise be discarded. Conclusion: The use of bovine pericardium to create millimetric sutures mimics human vascular tissue and is a low-cost procedure that allows the training of microsurgical skills.

Eight years experience of transanal endoscopic microsurgery

Introduction: Transanal Endoscopic Microsurgery (TEM) is a minimally invasive method for management of different proctologic conditions. Despite widespread use of this method, it is not used widely in Iran. This report is about to describe the application of TEM in managing different proctologic conditions in a tertiary colorectal referral center in Iran regarding methods and complications. Methods: All of the patients' documents such as procedure, method, early postop complications and further operations were actively reviewed and the data were entered in to the database. Results: Since 2012 till the end of 2020 chart review was done and 150 cases of TEM operation were found. The most frequent procedure that was done was resection procedure. Using different energy devices during surgery or suturing versus not suturing the defect were not associated with complication. There was a case of in hospital mortality and one case delayed perianal fistula following TEM. Measurement of lesion distance from anal verge was not significantly different using TEM or colonoscopy. Villous adenomas detected in colonoscopy were mostly associated with malignancy. In evaluated resected lesions most of cases had free base and distance from anal verge or using different energy devices were not associated with obtaining free base. Conclusion: TEM is a safe minimal invasive procedure with acceptable complications that could be helped in managing different proctologic conditions and the results of reviewing our patients revealed the same results that is reported from other colorectal centers.

Surgical and Clinical Outcomes Associated With the Use of Barbed Sutures and Self-Adhering Mesh System and Polymeric Glue for Wound Closure in Multilevel or Revision Spinal Surgery: A Matched Cohort Comparative Study With Conventional Wound Closure Procedure.

OBJECTIVE: Multilevel or revisional posterior spinal surgery is prone to infection and delayed wound healing, related with the wound closure time and suture strength. Knotless barbed suture is an innovative self-locking, multianchor suture. This study aims to evaluate the safety and efficacy of the knotless barbed suture and self-adhering mesh with polymeric glue in multilevel or revisional posterior spinal surgery. METHODS: This is a single-center retrospective matched cohort study. Patients were divided into 2 groups based on the wound closure method: barbed suture group with novel wound closure, and conventional suture group with conventional wound closure, 1:1 matched by the level of surgery and sex, resulting in 120 subjects each. Total operation time and wound closure time were measured intraoperatively, and perioperative clinical outcome parameters including postoperative wound complication were investigated for the first 3 months postoperatively. The distribution of continuous variables was assessed for normality by Shapiro-Wilk test, then parametric or nonparametric tests were applied accordingly (paired t-test or Wilcoxon signed-rank test). RESULTS: Wound closure time was significantly shorter with the novel barbed suture than with conventional suture in all subgroups divided by the level of spinal surgery: 3-5, 6-9, ≥ 10 levels (p < 0.001). The 2 groups showed no significant differences in surgical complications (p = 1.000). Specially, total operation time and wound-closing time were significantly shorter in revisional subgroup. CONCLUSION: Absorbable knotless barbed suture and self-adhering mesh with polymeric glue can shorten spinal wound closure time with noninferiority in complications for multilevel or revisional spinal surgery.

Addition of Transfixation Suture to Purse String Suture During Intraperitoneal Inguinal Hernia Repair Increases Peri-Hernia Sac Neck Collagen Formation.

BACKGROUND: The worldwide accepted repair for indirect inguinal hernia in children is high ligation of the hernia sac with open herniotomy. However, laparoscopic pediatric inguinal hernia repair (IHR) has been gaining popularity in the last two decades. An experimental study was conducted to investigate the effects of different intraperitoneal IHR suture techniques on the collagen formation at the hernia sac neck. METHODS: Present study was conducted on thirty-five male adult (3-6 months old) Wistar-Albino rats (260-300 g). Intraperitoneal IHR with different hernia sac neck suturing techniques (purse string suture only, transfixation suture only and purse string suture plus transfixation suture) were performed through median laparotomy using open operative techniques. Non-absorbable 2/0 braided polyester suture with 16 mm 1/2 curved round needle (Ti-cron, Covidien, MN) was used as suture material. RESULTS: The highest collagen thickness around the suture was detected in intraperitoneal IHR with purse-string plus transfixation suture group. The collagen thickness of the intraperitoneal IHR with purse string suture only and IHR with tranfixation suture only groups were not statistically significantly different. The collagen thickness of the intraperitoneal IHR with purse string suture plus transfixation suture group was statistically significantly higher compared with the intraperitoneal IHR with purse string suture only and intraperitoneal IHR with transfixation suture only groups. CONCLUSIONS: The combined usage of purse string suture and transfixation suture during laparoscopic intraperitoneal inguinal hernia repair further stimulates mesothelial fibrosis at the hernia sac neck compared with mesothelial fibrosis induced by purse string suture only or transfixation suture only.

Continuous suture technique increases the complete closure rate of colorectal mucosal defects after endoscopic resection: a single-blind, randomized controlled trial.

BACKGROUND: Complete closure of mucosal defects after colorectal endoscopic submucosal dissection (ESD)/piecemeal endoscopic mucosal resection (p-EMR) procedures reduces postoperative adverse events, but the complete closure rate of the traditional method using only hemostatic clips is not satisfactory. Therefore, we invented a continuous suture technique using a barbed suture and clips to increase the complete closure rate of colorectal mucosal defects. METHODS: Patients with a single large (≥ 2 cm) colorectal lesion were recruited. After completion of the ESD/p-EMR procedures, they were randomly allocated to the treatment group or control group. The mucosal defects of the treatment group were closed using barbed suture and clips, while the control group was closed using only clips. RESULTS: From January 18, 2022 to April 13, 2022, a total of 62 patients with colorectal lesions were enrolled, with 31 patients in each group. Complete closure was achieved in 29 patients (93.5%) in the treatment group and 18 patients (58.1%) in the control group (P = 0.001). The median closure time was 13 min in the treatment group and 19 min in the control group (P < 0.001). The median closure speed was 6.4 cm2/10 min in the treatment group and 3.5 cm2/10 min in the control group (P = 0.008). CONCLUSIONS: This study provided a clinically feasible continuous suture technique that was safe and effective for the complete closure of colorectal mucosal defects after endoscopic resection.

Comparison of modified gunsight suture technique and traditional interrupted suture in enterostomy closure.

BACKGROUND: Prophylactic enterostomy surgery is a common surgical approach used to reduce the risk of anastomotic leakage in patients who have undergone partial intestinal resection due to trauma or tumors. However, the traditional interrupted suturing technique used in enterostomy closure surgery has several issues, including longer surgical incisions and higher incision tension, which can increase the risk of postoperative complications. To address these issues, scholars have proposed the use of a "gunsight suture" technique. This technique involves using a gunsight incision instead of a traditional linear incision, leaving a gap in the center for the drainage of blood and fluid to reduce the risk of infection. Building on this technique, we propose an improved gunsight suture technique. A drainage tube is placed at the lowest point of the incision and close the gap in the center of the gunsight suture, which theoretically facilitates early postoperative mobility and reduces the burden of dressing changes, thereby reducing the risk of postoperative complications. AIM: To compare the effectiveness of improved gunsight suture technique with traditional interrupted suture in closing intestinal stomas. METHODS: In this study, a retrospective, single-center case analysis was conducted on 270 patients who underwent prophylactic ileostomy closure surgery at the Department of Colorectal Surgery of Qilu Hospital from April 2017 to December 2021. The patients were divided into two groups: 135 patients received sutures using the improved gunsight method, while the remaining 135 patients were sutured with the traditional interrupted suture method. We collected data on a variety of parameters, such as operation time, postoperative pain score, body temperature, length of hospital stays, laboratory indicators, incidence of incisional complications, number of wound dressing changes, and hospitalization costs. Non-parametric tests and chi-square tests were utilized for data analysis. RESULTS: There were no statistically significant differences in general patient information between the two groups, including the interval between the first surgery and the stoma closure [132 (105, 184) d vs 134 (109, 181) d, P = 0.63], gender ratio (0.64 vs 0.69, P = 0.44), age [62 (52, 68) years vs 60 (52, 68) years, P = 0.33], preoperative body mass index (BMI) [23.83 (21.60, 25.95) kg/m² vs 23.12 (20.94, 25.06) kg/m², P = 0.17]. The incidence of incision infection in the improved gunsight suture group tended to be lower than that in the traditional interrupted suture group [ (n = 2/135, 1.4%) vs (n = 10/135, 7.4%), P < 0.05], and the postoperative hospital stay in the improved gunsight suture group was significantly shorter than that in the traditional interrupted suture group [5 (4, 7) d vs 7 (6, 8) d, P < 0.05]. Additionally, the surgical cost in the modified gunsight suture group was slightly lower than that in the traditional suture group [4840 (4330, 5138) yuan vs 4980 (4726, 5221) yuan, P > 0.05], but there was no significant difference in the total hospitalization cost between the two groups. CONCLUSION: In stoma closure surgery, the improved gunsight technique can reduce the incision infection rate, shorten the postoperative hospital stay, reduce wound tension, and provide better wound cosmetic effects compared to traditional interrupted suture.

The Elbow's Achilles Heel: A Systematic Review and Meta-Analysis of Triceps Tendon Rupture and Repair Techniques.

Triceps tendon avulsion is a rare but debilitating condition and the least frequent of all tendon injuries, but it is receiving increasing attention in the literature. The most common mechanism of injury is resisted extension, which is typically seen in a fall onto an extended hand. Such injuries are easily overlooked and should be considered a differential diagnosis in all patients who describe pain and swelling at the posterior aspect of the elbow following a traumatic event. Non-operative management is the general principle for partial rupture as opposed to a variety of surgical treatments for a complete avulsion. The goal of this meta-analysis is to analyse the current literature on triceps avulsion and provide a detailed overview of the occurrence, diagnosis, treatment options and outcomes, comparison of various repair techniques, and consequences of this injury.

Surgery was urgent in 80% of the group with total stitch closure; and elective in 75% of the closing cases with subtotal points. The incision was median supra and infraumbilical in 70% of the patients in the group with total suture closure; and xiphopubic in 66.7% of those at closure with subtotal points. There were medians of 3 ± 2 and 1 ± 0 complications for closure with total stitches and closure with subtotal stitches, respectively. Median hospital stay was longer in the total stitch closure group (8 ± 6 days). Conclusions in the patients where internal subtotal sutures were applied for abdominal wall closure, the results were better than in the group where total sutures were used.

The application of an intraoral banana peel suturing model in surgical training of dental students.

OBJECTIVES: This study investigated the application of an intraoral banana peel suturing model in helping students to acquire intraoral surgical techniques. METHODS: This is a self-control study conducted from January 2021 to March 2021. An intraoral banana peel suturing model was implemented to provide oral suture experience for undergraduates majoring in stomatology. The sutures students placed in the model were photographed and evaluated blindly by a professional team using an established scoring system. Training scores were recorded before (training 1) and after 2 months of training (training 2). Linear regression was used to examine factors related to the scores. Suturing training was conducted in the School and Hospital of Stomatology at Peking University. A total of eighty-two students in Peking University School and Hospital of Stomatology were in their fourth pre-clinical year and followed a workshop on surgical sutures according to the curriculum. All students who should take this course were included, and the response rate was 100%. RESULTS: The mean training 2 score (23.04 ± 3.83) was higher than the mean training 1 score (13.94 ± 3.15). The training 1 score was not significantly correlated with any of the students' general characteristics. The training 2 score was correlated with the training 1 score and the cumulative duration of practice outside of class. CONCLUSION: The intraoral banana peel suturing model can be used for suture training, and dental students' suture ability was improved after using the banana peel for suture practice.

Functional Shoulder Evaluation after Osteosynthesis of Greater Tuberosity Fracture: Is There any Influence of Glenohumeral Dislocation?

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.
