Accessory thoracic muscles in human fetuses.

BACKGROUND: Typically, the anterior thoracic wall musculature is composed of the pectoralis major and pectoralis minor. Embryologically, these two muscles are originated from a common pectoral muscle mass; therefore, disruption of the normal development and differentiation could give rise to an aberrant or accessory muscle. The main aim of this study is to demonstrate and classify the accessory muscles of the pectoralis region in human fetuses. MATERIAL AND METHODS: Fifty spontaneously aborted human fetuses (25 male and 25 female, 100 sides) aged 18-38 weeks of gestation at death, and fixed in 10% formalin solution were examined. Following parental approval, the fetuses were donated to the Medical University anatomy program. The pectoralis major and minor muscle's morphology, the possible occurrence of accessory muscles of pectoral region and its morphology, their origins, and insertions, as well as the morphometric details, were assessed. RESULTS: The pectoralis major and minor were bilaterally found in all fetuses (100 cases). The accessory muscles of pectoral region were found in 16 cases (16%), and four types were differentiated. The Pectoralis Quartus muscle was the most common type of accessory muscles found in this study and occurred in 8 cases. The axillary arch muscle was observed in 3 cases. The chondrocoracoideus muscle was observed in 3 cases. The sternalis muscle occurred in 2 cases, and one of them was bifurcated. CONCLUSIONS: The thoracic region is characterized by a large amount of morphological variations, which are observed not only in adult population, but also among human fetuses. The pectoralis quartus was the most frequent variation in this study. Accessory structures like sternalis muscle, chondrocoracoideus muscle, pectoralis quartus muscle, or axillary arch muscle may have clinical implications, and knowledge about them is very useful for clinicians, especially plastic surgeons, thoracic surgeons, and orthopedics.

Pectoral major myocutaneous flap in our practice: about 25 cases.

The pectoralis major myocutaneous flap (PMMF) was described by Ariyan in 1979 for head and neck reconstructions. It is a safe flap, currently supplanted by free flaps in developed countries, but which remains very useful in developing countries. We report a series of 25 cases of PMMF reconstruction. All patients were treated for advanced stages of oral cavity cancer, where tumor excision left significant tissue loss. The reconstruction used PMMF, taken using the same technique. Supplanted by free flaps in developed countries, PMMF remains useful in developing countries. It is a flap that has numerous advantages (ease of collection, viability, low requirements in terms of instrumentation, etc.). Many variations have been described over the years.

Long-term outcomes of pectoralis major transfer for scapular winging due to long thoracic nerve palsy: results after a median follow-up of 17 years.

Background: A pectoralis major (PM) transfer is a viable treatment option for patients with scapular winging due to long thoracic nerve (LTN) palsy not responding to nonsurgical management. However, the long-term outcomes remain unknown. Therefore, the purpose of this study was to evaluate the long-term outcome of shoulder function (ie, minimum follow-up of 10 years) and quality-of-life (QoL) of patients treated for scapular winging due to LTN palsy with a PM transfer. Methods: This observational cohort study included 15 patients (16 shoulders) who underwent PM transfer, using a tendoachilles allograft, between 1995 and 2012. Shoulder forward flexion and abduction were analyzed preoperatively, 1 year after surgery and at the final follow-up. SF-36 component scores (physical component summary (PCS) and mental component summary (MCS)) were used to evaluate the QoL. Results: Shoulder forward flexion and abduction measured in degrees improved from 86 (SD 14.5) and 82 (SD 33.8) preoperatively to 140 (SD 27.3) and 138 (31.3) at 1 year postoperatively. After a median follow-up of 17 years, mean shoulder functions were slightly lower than at 1 year postoperatively, but still better than preoperative function, ie, forward flexion 121 (SD 41.9) and abduction 122 (SD 44.5). The mean PCS score at the final follow-up was 41.9 (SD 9.7), and the mean MCS score was 49.9 (SD 12.5). Better shoulder function at the final follow-up was significantly associated with higher QoL in terms of PCS scores (P = .023), but not MCS scores (P = .287). Conclusion: The results of the present study indicate that PM transfer augmented with an achilles tendon allograft for scapular winging due to LTN palsy leads to functional improvements that persist in long term. These functional improvements likely translate to better QoL based on their association.

Fascia lata autograft for chronic Pectoralis Major ruptures - A technical note.

Rupture of the pectoralis major tendon is an uncommon injury but increasing in incidence. Surgical management is often needed, and ruptures treated acutely show more favorable results. However, a significant number of ruptures are missed and diagnosed later in a chronic state. Direct suture without tension is a major challenge in these cases, and interposition grafts are required. Several techniques have been described however none uses a fascia lata autograft. This technical note aims to describe fascia lata autograft as a valid option to treat retracted chronic pectoralis major ruptures. LEVEL OF EVIDENCE: IV; Study Design: Technical Note.

Pectoralis Major Transfer For Anterior Recurrent Dislocation of Reverse Total Shoulder Arthroplasty: A Case Report.

Introduction: Reverse total shoulder arthroplasty (RTSA) has revolutionized the treatment landscape for a spectrum of shoulder pathologies, extending its indications from rotator cuff arthropathy to encompass irreparable rotator cuff lesions, fractures, inflammatory arthritis, and tumors. However, the exponential increase in RTSA usage has brought a proportional rise in associated complications, with dislocation being one of the most common early post-operative complications. Case Report: This case report details a 65-year-old right-hand dominant male patient presenting with chronic pain and weakness in the right shoulder, diagnosed with advanced glenohumeral arthritis and massive irreparable rotator cuff tears. The patient underwent a Bony Increased- Offset RTSA (BIO-RTSA) procedure, coupled with subscapularis repair. Postoperatively, the patient experienced pain and instability, culminating in an atraumatic anterior dislocation at 4 months. Despite conservative management, recurrent dislocations persisted. Revision surgery was performed with an increase in the linear component size for containment. About 1 year postoperative of the revision surgery, recurrent dislocation reoccurred. Re-revision surgery was performed with secondary pectoralis major (PM) transfer for subscapularis deficiency due to re-tear from recurrent dislocation, and with an increased humeral tray size for better containment. About 1-year and 6-month post-operative to the re-revision surgery, the patient achieved restored stability, improved range of motion, and reported satisfaction with the outcome. Conclusion: This case report underscores the challenges of managing recurrent anterior dislocation after RTSA. The successful use of secondary PM transfer highlights its efficacy as a salvage procedure in restoring stability for persistent anterior dislocation after RTSA. Yet, further clinical studies are warranted to establish the role of such interventions in the management for RTSA-associated complications. Level of Evidence IV: Case report.

Pectoralis Major Tendon Rupture Repairs Using Intramedullary Suture Anchors Shows High Patient Reported Outcomes in Military Service Members.

BACKGROUND: In the general population pectoralis major tendon ruptures are uncommon; however, it is a common injury in the military population. The military service members have greater physical demands than the general population. The purpose of this study is to critically assess the post-operative outcomes of pectoralis major tendon ruptures in military service members following a repair using intramedullary suture anchors. PURPOSE: To report outcomes of pectoralis major repairs utilizing intramedullary suture anchors in military service members. METHODS: A retrospective chart review was performed between 2014 to 2022, identifying patients who underwent a pectoralis major rupture repair performed by the senior surgeon using intramedullary suture anchors. Records were reviewed for age, gender, mechanism of injury, chronicity, VAS, and SANE scores. Patients who had less than 1 year of follow-up were excluded from the study. During the study period, 18 patients underwent surgical repair of their torn pectoralis major, and 15 patients were greater than 1-year post-operative. Twelve of these 15 patients (80%) were successfully contacted, and patient reported outcomes were collected. RESULTS: A total of 12 patients (12 male, 0 female) with a mean age of 34.5 years, were identified. Average time from injury to surgery was 471.4 days. The average duration of follow-up was 3.7 years. There was a decrease in the preoperative average single repetition maximum (1RM) barbell bench press of 277 lbs to a postoperative average 1RM bench press of 225 lbs (p-value=0.03). The average change in average 1RM barbell bench press is a 19.04% decrease postoperatively. Postoperative SANE score was 80.8 and an ASES of 86.9. Seven patients (58.3%) stated that they were afraid to bench press at their previous weight due to fear of reinjury. None of the patients were medically discharged from the military due to limitations from their repaired shoulder. Ten patients (83%) reported that they were extremely satisfied with their shoulder function post-operatively. CONCLUSION: Repair of the pectoralis major tendon ruptures using intramedullary suture anchors has high rates of return to duty, patient satisfaction and patient reported outcomes. Greater than half of the patients reported that they were afraid to bench press at their preinjury weight due to concerns of reinjury; the decrease in post-operative strength may be a result of the patients' fear of reinjury rather than physiologic limitations.

Tubed myocutaneous pectoralis major flap: A rescue option in esophagus reconstruction.

This article presents a complex case of total pharyngoesophageal defect reconstruction in a patient with recurrent supraglottic squamous cell carcinoma. After failed attempts with free microsurgical techniques due to complications, a tubed myocutaneous pectoralis major flap was successfully employed. The procedure aimed to achieve alimentary continuity, speech, and swallowing functionality. Despite initial challenges and concerns about stenosis, the reconstruction of a total pharyngolarygectomy defect resulted in a good functional outcome, although minor deficits in neck mobility and aesthetic donor zone deformities were noted. The case highlights the broad armamentarium of reconstruction techniques that plastic and aesthetic surgery teams must be trained, namely the myocutaneous pectoralis major flap which in selected cases can be the end solution.

Granulomatous mastitis and pectoralis major muscle defect following polyacrylamide hydrogel injection: a case report and literature review.

Background: Breast augmentation through the injection of polyacrylamide hydrogel (PAAG) was a popular procedure in the past, but it has since been prohibited due to various complications, including masses, migration, infection, inflammation, and even cancer. However, there were rare cases of granulomatous mastitis with pectoralis major muscle defect following PAAG injection for breast augmentation. Case Description: A 40-year-old female patient presented with a swollen and suppurative mass in her left breast and was insensitive to antibiotics. She was admitted to our department for further treatment after 7 months with progressive local and general symptoms. Ultrasound imaging showed ill-defined heterogeneous echoes, and contrast-enhanced magnetic resonance imaging (MRI) revealed non-mass enhancement lesions in the multiregional distribution in Breast Imaging-Reporting and Data System 4A (BI-RADS 4A) with oedema in the retroglandular space and multiple enlarged lymph nodes in the ipsilateral axilla. Intraoperative observations revealed necrotic tissues, multiple abscesses, residual mucoid PAAG prosthesis diffused into the mammary glands and intramuscularly into the pectoralis muscle, and partial loss of pectoralis major muscle. Histopathological results revealed foreign-body granulomas accompanied by gel-like granular PAAG and proliferative inflammatory cells. She recovered after undergoing the characteristic surgical management in our center under general anesthesia and had no recurrence during the 2-year follow-up. Conclusions: This case revealed that PAAG injection for augmentation mammaplasty, even after the removal operation, could result in subsequent complications, including granulomatous mastitis and pectoralis major muscle damage. PAAG filler complications are difficult to treat, therefore, it is essential to establish appropriate and effective therapeutic procedures.

Oxidative stability in meat (pectoralis major) of broiler orally supplemented with essential oils of allium sativum, Curcuma longa, Zingiber officinale, and Cinnamomum zeylanicum.

Lipid oxidation is a normal process in living muscles, but is escalated postmortem due to the loss of inherent antioxidant defense, which causes quality deterioration of meat. This study investigates the effects of essential oil (EO) supplementation to the drinking water of broiler chicken on physical properties, antioxidants, and lipid oxidation in Pectoralis major during frozen storage. Two hundred day-old chicks of arbo acre were allocated to five groups; control (T1) and the groups supplemented with: Allium sativum (T2), Curcuma longa (T3), Zingiber officinale (T4) and Cinnamomum zeylanicum (T5) at the level of 300ml/L into drinking water throughout a 49-d study. Thereafter, birds were slaughtered and breast meat excised for assessments during a 28-d storage period at 4 °C using standard procedure. The results show that cooking loss of Pectoralis major from T1 birds was not significantly (P > 0.05) different from that of T4, and were significantly higher than those of T2, T3, and T5 birds. Meat from T5 birds showed the lowest drip loss. The results for total antioxidant activity are not similar among sampling days. In general, control group showed inferior values, but T2 and T4 had greater values on days 0 and 28. The rate of lipid peroxidation increased with time; however, EOs administration markedly reduced the peroxidation rates compared to controls. The catalase activity of breast meat was significantly declined from day 14, but was enhanced as an effect of EO consumption especially in group T5 at 21 and 28 d. Supplementation of garlic, turmeric, and cinnamon EOs to broiler chickens increased glutathione peroxidase in breast meat on days 21 and 28, while turmeric EO enhanced superoxide dismutase up to 7 d. In conclusion, EOs are valuable supplements for broiler chickens and potent in enhancing meat quality and prolonging the shelf life.

Optimizing pectoralis major tendon repair: a modified knotless suture anchor technique using high-strength suture and tape.

Background: Rupture of the pectoralis major (PM) tendon is infrequent but has shown an increased incidence in athletes, particularly weightlifters during bench presses. Various techniques for repair exist, yet no established gold standard has been defined. Methods: We present a modified surgical technique utilizing knotless suture anchors for PM tendon repair. The technique involves bringing the tendon end superiorly and inferiorly to the decorticated bone surface, ensuring broader tendon-to-bone contact. Knotless anchors with a unique suture locking mechanism facilitate tension adjustment. Additionally, the repair's strength is reinforced by employing both surgical tape and high-strength suture. Results: The utilization of both surgical tape and high-strength suture in conjunction with knotless suture anchors provides a secure and stable construct. This approach minimizes the risk of failure, reduces the potential for neurovascular injury associated with bicortical drilling, preserves imaging quality due to the absence of metal artifacts, and helps avoid the risk of fracture associated with traditional methods. However, surgeons should be aware of a potential disadvantage of increased surgical costs compared to traditional techniques. Conclusion: Our modified technique offers multiple advantages, including increased tendon-to-bone contact, enhanced stability, reduced neurovascular risks, and avoidance of potential fractures. This makes it a valuable option for successful PM tendon repairs. Surgeons should consider its benefits and weigh them against the associated costs for optimal patient care.

Pectoralis major tendon transfer in reverse total shoulder arthroplasty with irreparable subscapularis: surgical technique and preliminary clinical and radiological results.

Hypothesis/Background: Addressing irreparable subscapularis in conjunction with reverse total shoulder arthroplasty (RTSA) presents challenges. RTSA without subscapularis repair leads to similar clinical results compared to those with a subscapularis repair but with less range of motion in internal rotation (IR). Optimization of IR and anterior stability after RTSA, in the setting of an irreparable subscapularis may be achieved with a pectoralis major (PM) tendon transfer. This study aims to describe a novel surgical technique involving PM transfer in RTSA for irreparable subscapularis and report the initial clinical and radiological outcomes. Methods: This study included 13 patients with an average of 65.5 years (range, 52-82 years). All patients underwent a lateralized RTSA with concurrent PM transfer, associated to an irreparable subscapularis, performed by a single surgeon (PV). Preoperative and postoperative range of motion, including internal rotation 1, internal rotation 2, external rotation 1 (ER1) and forward elevation, were measured. The absolute Constant score, the age and sex-adjusted Constant Murley score, Visual Analog Scale and subjective shoulder value were evaluated by the same surgeon. Standard X-rays, preoperative magnetic resonance imaging, and computed tomography scan were performed for all patients. Results: With an average follow-up of 37 months, the mean Constant score improved from 17.7 preoperatively to 61 postoperative (P < .05). Postoperative clinical outcomes significantly improved across the study group. Mean internal rotation 2 increased from 44.6° to 61.5° (P < .05), while internal rotation 1 improved from 2.6 to 5 (P < .05). The Gerber test yielded positive results for all patients, while the belly press test was negative for eleven patients. Postoperative imaging assessment of the transferred PM tendon transfer showed intact repair, a good cicatrization on the lesser tuberosity with excellent trophicity of the muscle without any fatty infiltration in all patients. Conclusion: PM transfer combined with a lateralized RSTA in cases of irreparable subscapularis leads to improved shoulder range of motion, particularly in IR, increased strength and pain relief.

Reconstruction of Partial Hypopharyngeal Defects following Total Laryngectomy: A Systematic Review and Meta-Analysis.

BACKGROUND: Various operative techniques exist to reconstruct partial hypopharyngeal defects following total laryngectomy. The current study aimed to investigate and compare complications and functional results following commonly used reconstructive techniques. METHODS: A systematic review and meta-analysis were performed using studies that investigated outcomes after the reconstruction of a partial hypopharyngeal defect. The outcomes of interest were fistulas, strictures, flap failure, swallowing function and postoperative speech. RESULTS: Of the 4035 studies identified, 23 were included in this review. Four common reconstructive techniques were reported, with a total of 794 patients: (1) pectoralis major myocutaneous and (2) myofascial flap, (3) anterolateral thigh free flap and (4) radial forearm free flap. Fistulas occurred significantly more often than pectoralis major myocutaneous flaps (34%, 95% CI 23-47%) compared with other flaps (p < 0.001). No significant differences in the rates of strictures or flap failure were observed. Pectoralis major myofascial flaps were non-inferior to free-flap reconstructions. Insufficient data were available to assess speech results between flap types. CONCLUSION: Pectoralis myocutaneous flaps should not be the preferred method of reconstruction for most patients, considering their significantly higher rate of fistulas. In contrast, pectoralis major myofascial flaps yield promising results compared to free-flap reconstructions, warranting further investigation.

Antibiotic-loaded bone cement fixation technique combined with bilateral pectoralis major muscle flaps tension-free management for sternal infection after midline sternotomy.

INTRODUCTION: Deep sternal wound infection (DSWI) after midline sternotomy of cardiac surgery is a challenging complication that affects the outcome of surgery. This study aims to assess the clinical effectiveness of the antibiotic-loaded bone cement fixation technique combined with bilateral pectoralis major muscle flaps tension-free management in the treatment of DSWI. METHODS: We retrospectively analyzed 5 patients with DSWI who underwent antibiotic-loaded bone cement combined with bilateral pectoralis major muscle flaps for chest wall reconstruction after sternotomy for cardiac surgery in a tertiary hospital in China from January 2020 to December 2021. The clinical and follow-up data were retrospectively analyzed. RESULTS: All patients had no perioperative mortalities, no postoperative complications, 100% wound healing, and an average hospital stay length of 24 days. The follow-up periods were from 6 to 35 months (mean 19.6 months). None of the cases showed wound problems after initial reconstruction using antibiotic-loaded bone cement combined with bilateral pectoralis major muscle flaps. CONCLUSIONS: We report our successful treatment of DSWI, using antibiotic-loaded bone cement fixation technique combined with bilateral pectoralis major muscle flaps tension-free management. The clinical and follow-up results are favorable.

Pectoralis major muscle flap reconstruction after a total laryngectomy widened anteriorly: A case report.

INTRODUCTION AND IMPORTANCE: The pectoralis major flap is one of the leading regional pedicled flaps for reconstructive surgery of the head and neck, particularly in oncology after tumor resection. Despite the increasing use of free flaps, this type of flap is still highly recommended in defined indications. It is a highly reliable flap in terms of viability. CASE PRESENTATION: We report the case of a man treated in our ENT department for a squamous cell carcinoma of the three laryngeal stages, anteriorly very extensive and requiring total laryngectomy extended to the skin and subcutaneous planes opposite, followed by reconstruction with a flap of the pectoralis major muscle. Post-surgical outcome was excellent. CLINICAL DISCUSSION: Aryan was the first person to describe the use of the pectoralis major muscle flap. Since then, several studies have demonstrated the great value of this flap in face and neck reconstruction, thanks to its wide indications and excellent viability rate. CONCLUSION: The pectoralis major muscle flap represents a valuable reconstructive option for substance loss in the cervicofacial region despite the great development of microsurgery and free flaps.

Biomechanical comparison of pectoralis major repair techniques: A systematic review and meta-regression.

Background: There are many surgical techniques when repairing pectoralis major tears. However, there is no clear consensus on which repair technique is biomechanically superior. Our purpose was to perform a systematic review and meta-regression to evaluate the most biomechanically superior pectoralis major repair technique. Methods: We performed a systematic review and meta-regression of six human cadaveric biomechanical studies evaluating fixation techniques for pectoralis major repairs. The primary outcome was the ultimate failure load. Covariates included cadaveric age, bone mineral density, implants, suture, and stitch method. Meta-regression accounted for differences in variables. Results: Compared with Krackow/Bunnell stitch method, the modified Mason-Allen stitch demonstrated a decrease in ultimate failure load by 220.6 N (95% CI, -273.0 to -168.2; p = <0.001). No differences were found between Krackow/Bunnell and whipstitch. There was an increase in ultimate failure load when utilizing suture tape by 206.6 N (95% CI, 139.5-273.7, p < 0.001). Suture anchors had a decrease in ultimate failure load by 88.1 N (95% CI, -153.4 to -22.8, p = 0.008) when compared to transosseous sutures. No differences were found between transosseous sutures and unicortical buttons. Discussion: We found the combination of suture tape in a whipstitch or Krackow/Bunnell stitch utilizing transosseous sutures or unicortical buttons is the most biomechanically superior construct for pectoralis major repairs.

Isolated Myocysticercosis of Pectoralis Major: A Rare Case.

Isolated myocysticercosis is a neglected tropical disease and a rare diagnosis, with only a handful of cases being reported in the literature. It is highlighted that recently, it has not only been limited to endemic regions but also persists globally due to widespread migration from endemic regions. We present a case of isolated myocysticercosis of the right pectoralis major without neurological involvement in a non-pork-eater. High-resolution ultrasonography is an effective method of diagnosis. Anti-helmintic drugs are effective treatment options; if not responding, surgical excision is the management of choice. Ultrasound-guided excision is a better treatment modality to prevent complications.

Automated analysis of pectoralis major thickness in pec-fly exercises: evolving from manual measurement to deep learning techniques.

This study addresses a limitation of prior research on pectoralis major (PMaj) thickness changes during the pectoralis fly exercise using a wearable ultrasound imaging setup. Although previous studies used manual measurement and subjective evaluation, it is important to acknowledge the subsequent limitations of automating widespread applications. We then employed a deep learning model for image segmentation and automated measurement to solve the problem and study the additional quantitative supplementary information that could be provided. Our results revealed increased PMaj thickness changes in the coronal plane within the probe detection region when real-time ultrasound imaging (RUSI) visual biofeedback was incorporated, regardless of load intensity (50% or 80% of one-repetition maximum). Additionally, participants showed uniform thickness changes in the PMaj in response to enhanced RUSI biofeedback. Notably, the differences in PMaj thickness changes between load intensities were reduced by RUSI biofeedback, suggesting altered muscle activation strategies. We identified the optimal measurement location for the maximal PMaj thickness close to the rib end and emphasized the lightweight applicability of our model for fitness training and muscle assessment. Further studies can refine load intensities, investigate diverse parameters, and employ different network models to enhance accuracy. This study contributes to our understanding of the effects of muscle physiology and exercise training.

Bilobed Pectoralis Major Myocutaneous Flap Reconstruction: a Single Institution Experience of 150 Patients and Methods to Prevent Complications.

Introduction: Bilobed PMMC flap is done for patients who have diseases that require resection of oral cavity mucosa along with the overlying skin, either because of direct tumor invasion to the skin or for achieving adequate tumor-free base of resection. The versatility of the flap allows it to be used to cover both inner and outer linings for a full-thickness defect. Materials and Methods: This was a single-center, retrospective, observational study carried out in the Department of Head and Neck Oncology at a regional cancer center from January 2019 to December 2019. A minimum follow-up duration for all patients was 6 months. The primary endpoint was to study the results and complications associated with bilobed PMMC flap reconstruction and factors affecting it, as well as their management. Results: The median age was 45 years [24-71 years]. There were 96(64%) males and 54(36%) females. The most common sites reconstructed were lower gingivobuccal sulcus (39.1%), buccal mucosa (30.2%), and lower alveolus (16.7%). The overall complication rate was 41.3%, with 10(6.6%) patients requiring re-exploration. The average hospital stay was 11 days [5-28 days]. On doing a multivariate analysis, for various factors affecting flap necrosis, none of the factors reached statistical significance (p value > 0.05). Conclusion: PMMC flap remains the workhorse of head and neck reconstruction. In cases of full-thickness defects in oral cancer patients, in our country, in the setup which lacks the expertise in microvascular anastomosis and with immense caseload in the head and neck cancer department, bilobed PMMC flap remains a safe and favorite alternative method for reconstruction.

Pectoralis Major Tendon Rupture in an Occupational Medicine Setting: A Case Report.

Pectoralis major (PM) rupture is a rare injury, commonly misdiagnosed, that affects mostly young male athletes aged 20-40 years. This type of injury is typically associated with weight lifting, especially bench pressing. In an occupational medicine setting, it is extremely rare and not much reported in the literature. We present the case of a 30-year-old trauma technician male who presented with right shoulder and chest pain following a popping sensation while pushing in full momentum a patient on a gurney accidentally set on break mode. PM rupture was suspected clinically. Magnetic resonance imaging confirmed the diagnosis and revealed a complete rupture of the sternal head of PM. Surgical reconstruction was performed to restore the anatomy and functionality of the shoulder girdle.
