ABSTRACT
OBJECTIVES & AIMS:• To evaluate the outcome of different Reconstructive surgery in oral cavity carcinoma• To determine the factors which increase the complication in post op reconstructive surgery(like – diabetes, hypertension, smoking etc.)• The effect of flap transfer on complication or on post op rehabilitation of patients in oralcavity carcinoma.MATERIALS AND METHODS: This is a prospective study conducted at GCS hospital,Ahmedabad between oct. 2021 to June 2022. Sample size is 40 patients with case of oral cavitycarcinoma, out of which some cases underwent for PMMC Flap, Radial forearm free flap, ALTfree flap, fibula flap, forehead rotational flap, deltopectoral flap and local flap.CONCLUSION:Risks have not increased complications in PMMC or Free flap group in our study. Various otherstudies have similar results however a larger patient pool may be needed to assess them. ThePMMC flap is more favorable for patients with possibly lethal pre-op morbidities, when a longoperation is not advisable and a small defect is expected as compared to the longer operationduration of ALT free flap & Radial free flap.Though the flap related complications & donor site related complications are more with foreheadrotational flap as compared to PMMC. ALT & Radial forearm free flap, statistically there is nosignificant difference. Also, in the functional post-op outcomes there is minimally statisticallysignificant difference with PMMC flap, ALT free flap or Radial free flap, local flaps and otherreconstructive surgery.

ABSTRACT
Objective:To explore the advantages and value for clinical application of clavicle segment osteotomy approach with pectoralis major muscle pedicle in surgical resection of posterior brachial plexus tumour.Methods:From April 2010 to December 2020, 6 patients with brachial plexus tumour behind the clavicle were treated. Two patients had the tumour on the left brachial plexus and 4 on the right. Two patients had the tumours located in the upper trunk of brachial plexus, 2 in the middle trunk, 1 in the medial plexus and 1 in the posterior bundle. The neurological function evaluation were grade II in 3 cases and grade III in 1 case preoperatively. The tumours sized from 3.0 cm× 3.0 cm×2.0 cm to 11.0 cm×8.0 cm×6.0 cm. The clavicular segment osteotomy approach with the pedicle of the pectoralis major was applied in order to expose the surgical field and remove the nerve tumour. All patients underwent regular postoperative outpatient clinic follow-up to record the sensation of the affected limb and the recovery of muscle strength, tumour recurrence and fracture healing.Results:In the operation, it was found that there was still a little glial-like tissue in the nerve sheath after complete dissection of the tumours in 2 patients. Postoperative pathological examination reported that there were 4 schwannoma, 1 malignant peripheral schwannoma and 1 neurolipoma. The postoperative follow-up lasted for 6 to 34 months, with an average of 12.8 months. All patients showed no symptoms of brachial plexus injury or tumour recurrence. The clinical symptoms were relieved or disappeared. The neurological function evaluation reached grade III in 5 patients and grade IV in 1 case. At the same time, the internal fixation of the clavicle was satisfactory and achieved bone union in all cases. Fracture healing time was 2.5 to 4.5 months, with an average of 3.2 months. The internal fixation was removed from 3 patients after operation in 1 year. No obvious limb movement disorder and periarthritis of shoulder and other complications occurred.Conclusion:The transclavicular osteotomy approach with the pedicle of the pectoralis major can fully expose the anatomical alignment of the brachial plexus and the relationship adjacent and between the tumour and the surrounding tissues in the surgery for a brachial plexus tumour behind the clavicle, which is helpful for a complete tumour resection. It is a feasible method to treat brachial plexus tumour behind the clavicle by finding residual tumour-like tissue, reducing the risk of surgery and tumour recurrence, and providing excellent blood supply to the osteotomy segment of the clavicle to promote fracture healing.
ABSTRACT
Objective:To analysis the effect of two methods of transposition of pectoralis major in different degrees deep sternal wound infection(DSWI) after undergoing cardiac surgery.Methods:128 patients with DSWI after cardiac surgery were treated, 72 were mild, and 56 were severe. 66 cases of pectoralis major muscle flap docking method(medial muscle flap docking group) and 62 cases of lateral pectoralis major muscle flap turnover method(lateral muscle flap turnover group) were implemented respectively. Drainage tube indwelling time, reoperation rate, incidence of lung infection, long-term thoracic stability and other aspects were observed to compared the treatment effect.Results:In the mild patients, the medial muscle flap docking group and the lateral muscle flap turnover group were compared( P<0.05). The postoperative hospital stay [(14.2±4.7)days vs.(17.1±3.9)days], drainage tube retention time[(6.2±1.7)h vs.(9.1±2.9)h], and reoperation rate(2.4% vs. 6.7%), the incidence of lung infection(14.3% vs. 23.3%), long-term thoracic stability[73.8%(31/42)vs.43.3%(13/30)]. In the severe patients, the medial muscle flap docking group and the lateral muscle flap turnover group were compared. The postoperative hospital stay[(24.2±7.2)days vs.(20.1±3.5)days], drainage tube retention time[(20.2±6.6)h vs.(13.2±3.1)h], reoperation rate(20.8% vs.12.5%), incidence of pulmonary infection(41.7% vs. 31.3%), long-term thoracic stability[25.0%(6/24)vs.68.8%(22/32)]. The differences of the indicators in each group were significant , P<0.05. In the mild group, each index of the pectoralis major medial muscle flap docking method was superior to the lateral muscle flap turnover method, but the treatment results of the two methods in the severe group were opposite. Conclusion:Patients with mild deep DSWI treated with medial pectoralis major muscle flap docking and suture have less hospital stay, less reoperation rate, less complications and better treatment effect than reverse lateral pectoralis major muscle flap turnover. But the two treatments in the severe DSWI have the opposite effect.
ABSTRACT
@#OBJECTIVE: It is common to get lost during a comminuted proximal humerus surgery, and the pectoralis major insertion is always a constant. Therefore, this study aimed to do a cadaveric study on the Filipino population to assess the distance from the pectoralis major tendon to the top of the humeral head (PMT) as a reference during proximal humerus surgery. METHODS: This study dissected the shoulders of cadavers. The distance from the pectoralis major tendon insertion to the top of the humeral head (PMT) was measured using a caliper. This PMT distance was also correlated to the cadaver's height and sex. RESULTS: This study dissected 110 shoulders (55 cadavers | 24 females, 31 males). The median PMT was 5.40 cm for males and 4.90 cm for females, with a combined value of 5.40 cm overall. There was a direct and moderate correlation between the PMT with overall height. Height and PMT of both the left and right shoulder were significantly longer among males compared to females. The study showed that for every centimeter increase in the height of males, there was a corresponding 0.02 cm increase in the PMT, adding the constant factor of 1.83. A corresponding 0.04 cm increase in the PMT for females added the constant factor of -0.81. CONCLUSION; The pectoralis major tendon insertion is a consistent landmark that can accurately restore humeral length when reconstructing complex proximal humerus fractures where landmarks are otherwise lost because of comminution.

ABSTRACT
Abstract Introduction: Pharyngocutaneous fistula is the most significant complication after salvage total laryngectomy in patients who have received previous treatment with radiotherapy with or without chemotherapy. Objective: Our purpose is to review the fistula rate in radiated patients undergoing salvage total laryngectomy, to determine if the use of pectoralis major flap interposition reduces the incidence and duration of fistula and to examine other risk factors. Methods: We made a retrospective review of patients undergoing salvage total laryngectomy for exclusively larynx cancer after failure of primary curative radiotherapy between 2000 and 2017. General data from patients, risk factors and other complications were analyzed. Results: We identified 27 patients whose mean age was 66.4 years, mainly male (92.5%). The primary closure group without pectoralis major flap included 14 patients, and the group with pectoralis major flap closure included 13 patients. Pharyngocutaneous fistula was present in 15 patients (55.5%). Global pharyngocutaneous fistula rate was higher in the group of patients without pectoralis major flap comparing with those were the flap was interposed (78.6% versus 30.8%, p = 0.047). Also the pharyngocutaneous fistulas which need to be repaired with surgery (64.3% versus 7.7%, p = 0.03) and large pharyngostomes (64.3% versus 0%, p = 0.0004) were present in a higher rate in the group closed primary without pectoralis major flap. We did not find other risk factors with statistical significance. Oral diet initiation (84 days versus 21.5 days, p = 0.039) and the duration of hospitalization (98.3 days versus 27.2 days, p = 0.0041) were much lower in patients with a preventive pectoralis major flap. Two patients died as a consequence of complications of large pharyngostomes. Conclusions: Prophylactic pectoralis major flap reduced the incidence, severity and duration of fistula and should be considered during salvage total laryngectomy.
Resumo Introdução: A fístula faringocutânea é a complicação mais significativa após laringectomia total de resgate em pacientes que receberam tratamento prévio com radioterapia com ou sem quimioterapia. Objetivo: Revisar a taxa de fístula em pacientes irradiados submetidos a laringectomia total de resgate, para determinar se o uso de interposição de retalho do peitoral maior reduz a incidência e a duração da fístula e examinar outros fatores de risco. Método: Fizemos uma revisão retrospectiva de pacientes submetidos à laringectomia total de resgate para câncer exclusivamente laríngeo após falha da radioterapia curativa primária entre 2000 e 2017. Dados gerais dos pacientes, fatores de risco e outras complicações foram analisados. Resultados: Foram identificados 27 pacientes com média de 66,4 anos, principalmente do sexo masculino (92,5%). O grupo de fechamento primário sem retalho de peitoral maior incluiu 14 pacientes e o grupo de fechamento com retalho de peitoral maior incluiu 13 pacientes. Fístula faringocutânea esteve presente em 15 pacientes (55,5%). A taxa global de fístula faringocutânea foi maior no grupo de pacientes sem retalho de peitoral maior em comparação com aqueles que receberam o retalho (78,6% vs. 30,8%, p = 0,047). Além disso, as fístulas faringocutâneas que precisaram ser reparadas através de cirurgia (64,3% vs. 7,7%, p = 0,03) e grandes faringostomias (64,3% vs. 0%, p = 0,0004) apresentaram uma taxa mais alta no grupo fechado primariamente sem retalho do peitoral maior. Não encontramos outros fatores de risco com significância estatística. O início da dieta oral (84 dias vs. 21,5 dias, p = 0,039) e a duração da internação (98,3 dias vs. 27,2 dias, p = 0,0041) foram muito menores nos pacientes com uso preventivo do retalho do peitoral maior. Dois pacientes morreram em consequência de complicações de grandes faringostomias. Conclusões: O uso profilático do retalho do peitoral maior reduziu a incidência, a gravidade e a duração da fístula e deve ser considerado durante a laringectomia total de resgate.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a well-recognized public health problem throughout theworld. The evolution of new genetically distinct community-acquired and livestock-acquired MRSA and extended resistance toother non-β-lactams including vancomycin has only amplified the crisis. This paper presents data on the prevalence of MRSAand resistance pattern to other antibiotics on the selected specimen from burn patients.Materials and Methods: This is a prospective study conducted in the burn unit of Shyam Shah Medical College and SanjayGandhi Memorial Hospital, Rewa (M.P.), from June 2018 to May 2019, where all patients with flame and scald burns wereincluded in the study who had up to a second degree or partial-thickness burns.Results: A total of 558 patients were admitted in the burn unit throu`ghout the year, the age ranged from 2 months to 85 years.About 56.10% were females and 43.90% were males. Pseudomonas aeruginosa (37.5%) was the most common isolatefollowed by S. aureus (18.75%). The prevalence of MRSA was 57.14% but all the MRSA isolates showed 100% sensitivity tovancomycin and linezolid closely followed by piperacillin and tazobactam combination. The prevalence of methicillin resistanceoverall among S. aureus and Staphylococcus epidermidis was found to be 51.72%.Conclusion: MRSA is prevalent among the burn wounds but is 100% sensitive to vancomycin and linezolid. To ensure earlyand appropriate therapy, routine microbiological surveillance and a regular update of their antimicrobial susceptibility patterncould help in the prevention of development of multidrug resistance.
ABSTRACT
Variations in the pectoralis major (PM) muscles have been reported by various authors in the literature. We report a case of accessory slip of PM with variation in insertion which has not been reported in the literature to the best of our knowledge. This accessory slip was partially muscular getting inserted into medial lip of intertubercular sulcus (ITS) and partially aponeurotic getting inserted into lateral lip ITS, thus forming “H”-shaped pattern. Knowledge of such anatomical variation will create awareness among surgeons performing surgical reconstruction using PM muscle.
ABSTRACT

ABSTRACT
The musculus sternalis is an anatomical variant that occurs in 3-8 % of the world population and its incidence is higher in women. It can be found unilaterally or bilaterally and is located in the anterior wall of the thorax, where its fibers run parallel to the sternum and superficial to the medial part of the pectoralis major muscle. The main objective of this study was to quantify the incidence of musculus sternalis in the population of Caldas (Colombia) and, therefore, 68 cadavers of adult individuals were used during a period of twenty years to determine the incidence of this muscle and describe its anatomical characteristics. Two cadavers had this muscle, which was equivalent to 2.94 % of the sample, where one was located unilaterally and in other bilaterally. In the case of unilateral presence, the muscle presented an oblique direction thatdoes not coincide with any subtype of the classification given for these muscles. In bilateral presentation, both muscles were continuous at their upper ends with the respective sternocleidomastoid muscle. In addition, the right musculus sternalis had a digastric shape, which also does not coincide with any subtype of the classification.
El músculo esternal es una variante anatómica que se presenta entre el 3 % y 8 % de la población mundial y su incidencia es mayor en mujeres. Puede hallarse de manera unilateral o bilateral y se localiza en la pared anterior del tórax, donde sus fibras corren paralelas al esternón y superficial a la región medial del músculo pectoral mayor. El objetivo del presente estudio fue cuantificar la incidencia del músculo esternal en la población de Caldas (Colombia). Fueron revisados 68 cadáveres de individuos adultos durante un lapso de doce años, con el fin de determinar el grado de presencialidad del músculo y sus características anatómicas. Dos cadáveres, que equivale al 2,94 % de la muestra, presentaron el músculo esternal, uno de manera unilateral y el otro bilateral, a los cuales se les hizo una descripción anatómica detallada. En la presentación unilateral, el músculo presentó una dirección oblicua que no coincide con ningún subtipo de la clasificación dada para estos músculos. En la presentación bilateral, ambos músculos se continúan por su extremo superior con el respectivo músculo esternocleidomastoideo. Además, el músculo esternal derecho tiene una configuración digástrica, que tampoco coincide con ningún subtipo de la clasificación.

Abstract Introduction: The pectoralis major flap is a reconstructive option to consider in the treatment of pharyngocutaneous fistula after a total laryngectomy. There are not large studies assessing variables related to pharyngocutaneous fistula recurrence after removal of the larynx. Our objectives were to review the results obtained with this type of treatment when pharyngocutaneous fistula appears in laryngectomized patients, and to evaluate variables related to the results. Methods: We retrospectively reviewed our results using either a myocutaneous or fasciomuscular pectoralis major flap to repair pharyngocutaneous fistula in 50 patients. Results: There were no cases of flap necrosis. Oral intake after fistula repair with a pectoralis major flap was restored in 94% of cases. Fistula recurrence occurred in 22 cases (44%), and it was associated with a lengthening of the hospital stay. Performing the flap as an emergency procedure was associated with a significantly higher risk of fistula recurrence. Hospital stay was significantly shorter when a salivary tube was placed. Conclusions: The pectoralis major flap is a useful approach to repair pharyngocutaneous fistula. Placing salivary tubes during fistula repair significantly reduces hospital stay and complication severity in case of pharyngocutaneous fistula recurrence.
Resumo Introdução: O retalho do músculo peitoral maior é uma opção a ser considerada no fechamento de fístula faringocutânea pós-laringectomia total. Não há grandes estudos que avaliem as variáveis relacionadas à recorrência da fístula faringocutânea após esse procedimento. Nossos objetivos foram avaliar os resultados obtidos com esse tipo de tratamento em pacientes laringectomizados com fístula faringocutânea e as variáveis relacionadas aos resultados. Método: Revisamos retrospectivamente os nossos resultados em 50 pacientes nos quais um retalho miocutâneo ou fasciomuscular do músculo peitoral maior foram utilizados para reparar a fístula faringocutânea. Resultados: Não houve casos de necrose de retalho. Após o reparo da fístula com um retalho do músculo peitoral maior, a ingestão oral foi restaurada em 94% dos casos. Houve recorrência da fístula em 22 casos (44%), a qual foi associada à duração da hospitalização. O uso do retalho como procedimento de emergência foi associado a um risco significativamente maior de recorrência da fístula. A permanência hospitalar foi significativamente menor quando utilizado um tubo de derivação salivar. Conclusões: O uso do retalho do músculo peitoral maior é uma abordagem útil para reparar a fístula faringocutânea. A colocação de tubos de derivação salivar durante o reparo da fístula reduz significativamente o tempo de hospitalização e a gravidade das complicações em caso de recorrência da fístula faringocutânea.

Background of study- A detailed knowledge of variations in the origin and branching pattern of Thoraco-acromial artery(TAA) is important during various reconstructive and microvascular surgeries. Materials and methods- Hundred formalin xed specimens were studied at Government Medical College, Kozhikode, Kerala, India over a period of four years. Results- Normal quadrifurcation pattern was observed in majority of specimens (84%). The division of TAA into two trunks was seen in 9% followed by ramication into multiple branches in 4% specimens. Some specimens showed trifurcation (3%). Conclusion- In this scenario of increasing reconstructive surgeries, a thorough knowledge on the anatomical variations of TAA will be helpful to surgeons as this artery provides vascular supply to Pectoralis Major Myo-Cutaneous ap.
ABSTRACT
Objective@#To compare the pedicled supraclavicular artery island flap (SCAIF) and the pectoralis major myocutaneous flap (PMMF) for oral reconstruction after cancer resection.@*Methods@#This is a retrospective study from May 2007 to May 2017. Sixty-one patients from the Jiangxi University of Traditional Chinese Medicine and the First Affiliated Hospital of Nanchang University, were included. All the patients underwent oral squamous cell carcinoma resection and pedicled flap reconstruction. Sixteen patients were performed SCAIFs (group A), and 45 were performed PMMFs (group B). The flap survival rate, flap size, flap preparation time, the presence of scar hyperplasia, pigmentation and dysfunction (temporary or permanent) were compared between these two groups.@*Results@#The survival rate of flaps in group A was 93.75% (15/16), and the survival rate of flaps in group B was 95.56% (43/45). There was no statistically significant difference in the survival rate of flaps, the average skin flap size or flap produce time between these 2 groups. There were no scar hyperplasia, pigmentation and dysfunction was observed in group A. However, scar hyperplasia (n=11), pigmentation (n=10) and dysfunction (n=12) occurred in group B. The difference was statistically significant (P<0.05).@*Conclusions@#This study suggests that SCAIF is more reliable, and brings more satisfied outcome, when compared with the PMMF.
ABSTRACT
We report two cases with postoperative sternal osteomyelitis after coronary artery bypass graft (CABG), in whom successful two-stage reconstruction was performed via negative pressure wound therapy (NPWT) and pectoralis major myocutaneous flaps. Two patients underwent CABG using bilateral internal thoracic arteries, after which they had surgical site infection (SSI). The intractable wound did not heal with irrigation and NPWT. Then, sternal osteomyelitis was observed via magnetic resonance imaging (MRI), so we planned two-stage reconstruction. The first stage of treatment consisted of complete debridement (including removal of sternal wires and necrosectomy of soft tissue and sequestrum) and application of NPWT until the remission of inflammation. The second stage consisted of wound closure with pectoralis major myocutaneous advancement flaps. After wound closure, the two patients were given 2 months of oral antibiotics, and the postoperative results were good. Two-stage reconstruction with NPWT and pectoralis major myocutaneous flaps results in excellent clinical outcome. In the first stage, the key to the successful management of postoperative sternal osteomyelitis is infection control. This includes surgical debridement and wound-bed preparation with NPWT. The pectoralis major myocutaneous flap technique is brief and does not require a second cutaneous incision or an intact internal thoracic artery. In conclusion, the pectoralis major myocutaneous flap is a useful option in two-stage reconstruction after CABG.
ABSTRACT
To investigate the therapeutic effect of pectoralis major muscle flap transplantation in thoracotomy patients with sternal infection. Methods From January 2014 to December 2017, the treatment group of 39 patients with thoracic bone infection after cardiac surgery was used pectoralis major muscle flap to close the wound, while 26 patients were treated by debridement and vacuum sealing drainagea at the same time as the control group. The hospitalization time, hospital costs, number of operations, satisfaction survey, and relapse rate were compared between the those. Results Compared with the control group, the treatment group has the benefit of shorter hospitalization time [(18. 1 ± 3. 8)days vs. (36. 7 ± 11. 4) days], less hospital costs [(19429 ±4088)yuan vs. (33495 ±10712)yuan], less number of operations [(1. 1 ±0. 3)times vs. (2. 4 ±0. 8)times], higher level of satisfaction(56. 4％ vs. 30. 8％), lower relapse rate(5. 1％ vs. 26. 9％), the differences are statistically significant(all P <0. 05). Conclusion Thoracic reconstruction with pectoralis major muscle flap is an effective treatment for sternal infection in postcardiac surgery.
ABSTRACT
PURPOSE: This study investigated the effects of shoulder protraction exercise according to weight by examining the surface electromyography (EMG) amplitude in the serratus anterior (SA), upper trapezius (UT), and pectoralis major (PM) as well as the activity ratio of each muscle. METHODS: Twenty three winging scapula subjects participated in the study. The subjects performed scapula protraction at shoulder 90° flexion and 60° horizontal abduction with up to four (none, 1kg, 1.5kg, and 2kg) dumbbells in the supine position. The EMG data were collected from the dominant side muscles during a shoulder protraction exercise according to weight in the supine position. One way repeated measures analysis of variance (ANOVA) was used to compare the normalized activities of the SA, UT, and PM and the ratios of PM/SA and UT/SA. RESULTS: The results showed that the activities of both the SA and UT were highest for the shoulder protraction exercise at 2kg in the supine position. The UT/SA ratio also was the lowest for exercise at 2kg. On the other hand, the activities of both the UT and PM/SA ratio were similar under all conditions. CONCLUSION: These results show that there is a need to selectively strengthen the SA muscle in the case of patients with the shoulder dysfunction. In particular, it is necessary to weigh 2kg when performing shoulder protraction exercises in the supine position to activate the SA muscle in patients with a winging scapula.

SUMMARY: Anomalous muscle slips of pectoralis major have been reported on several cases in the literature. Among these, chondroepitroclearis muscle is an extremely rare aberrant muscular slip originating from the pectoral region. During an educational dissection, chondroepitroclearis muscle was found on the right side in a Korean cadaver. Tendinous muscular slip originated from pectoralis major muscle, crossing the neurovascular bundle in the arm, and inserted onto medial epicondyle of the humerus. Clinical significance of these anomalous slip can cause median nerve entrapment and functionally limited movement of the humerus. We report a case of tendinous chondroepitroclearis muscle and discuss its clinical and embryological significance.
RESUMEN: En la literatura se han reportado fascículos anómalos del músculo pectoral mayor. Entre estos, el condroepicondilar medial es un fascículo muscular aberrante extremadamente raro que se origina en la región pectoral. Durante una disección educativa, se encontró esta variación en el lado derecho de un cadáver coreano. El fascículo muscular tendinoso se originó a partir del músculo pectoral mayor, cruzando el paquete neurovascular en el brazo, y se insertó en el epicóndilo medial del húmero. La importancia clínica de estos fascículos anómalos radica en la posibilidad de causar el atrapamiento del nervio mediano, causando un movimiento funcionalmente limitado del húmero. Divulgamos un caso de músculo condroepicondilar medial tendinoso y discutimos su significado clínico y embriológico.

La rotura del tendón del pectoral mayor es considerada una lesión infrecuente en lo descrito en la literatura, pero esa lesión ha tenido un aumento exponencial en sus reportes a partir de los años 90. A continuación, presentamos la resolución quirúrgica de una rotura completa del tendón del pectoral mayor mediante una técnica simple y reproducible en un hombre de 34 años, sometido a una alta demanda física diaria. Tenemos ya publicado diferentes técnicas de reparación en periodo agudo como reconstrucción en lesiones crónicas. Nosotros presentamos una técnica de reparación para rotura aguda que consiste en la reinserción mediante anclas de titanio en su huella insercional mediante una configuración de suturas que forma un constructo estable y resistente, que permita al paciente rehabilitarse en forma precoz y satisfactoria para intentar volver al mismo nivel de actividad pre lesional. Con eso, aportamos al especialista una manera sencilla de enfrentarse y planificar la reparación de ese tipo de lesiones infrecuentes que no siempre estamos acostumbrados a resolver.
Pectoralis major tendon rupture is an infrequent injury in what has been described in the literature so far. Lately, an exponential increase in reported cases of this injury has been observed. We present a simple and reproducible surgical technique in a 34 years old male subject to a high daily physical demand. Different techniques have been published for tendon repair during the acute period as well as reconstruction in chronic lesions. We present a technique for acute rupture that consists of the reinsertion by means of titanium anchors in its insertional footprint through a suture configuration that forms a stable and resistant construct, that allows the patient to be rehabilitated in an early and satisfactory manner with the objective to return to the same Level of pre-injury activity. With this we provide the specialist with a simple way to manage the repair of these infrequent injuries.
