Muscle rupture sports

BACKGROUND: Semitendinosus/gracilis (STG) tendon autograft has been used effectively for restoring knee stability after anterior cruciate ligament (ACL) rupture. Though ACL reconstruction with STG autograft is an effective surgical technique for return to sports, short-term hamstring strength asymmetries exist after surgery. Although imaging evidence has demonstrated regrowth and reorganization of the semitendinosus (ST) tendon, no studies show whether the regrowth is associated with residual muscle function...

OBJECTIVES: To describe the Return to competition after Achilles Tendon rupture (ATR) in an elite soccer player. DESIGN: Case report. SETTING: Return to sport (RTS) of a professional soccer player who suffered an ATR during a match. The RTS phase started 15 weeks after surgery and specific on-field activities were gradually introduced. Criteria used to monitor the transition through the different phases were strength and endurance of the calf muscle and ability to sustain specific on-field training loads (TL) monitored with Global Positioning System and heart-rate system...

Orthobiologics are biological substances that allow injured muscles, tendons, ligaments, and bone to heal more quickly. They are found naturally in the body; at higher concentrations they can aid in the healing process. These substances include autograft bone, allograft bone, demineralized bone matrix, bone morphogenic proteins, growth factors, stem cells, plasma-rich protein, and ceramic grafts. Their use in sports medicine has exploded in efforts to increase graft incorporation, stimulate healing, and get athletes back to sport with problems including anterior cruciate ligament ruptures, tendon ruptures, cartilage injuries, and fractures...

BACKGROUND: The vast majority of biceps tendon ruptures occurs at the proximal insertion and almost always involves the long head. There are several options for long head of biceps (LHB) tenodesis with advantage and disadvantages of each technique. We believe that the suprapectoral LHB tenodesis described in this article enables the restoration of the anatomic length-tension relation in a technically reproducible manner, when following the guidelines set forth in this article, and restores biceps contour and function adequately with a low risk of complications...

INTRODUCTION: The pectoralis major is a very powerful muscle that forms the chest prominence and. It moves the shoulder forward and across your chest. It is best known as the muscle that you develop with the bench press exercise in gymnasium. The pectoralis major attaches to the humerus bone and is divided into two parts. The upper part is known as the "clavicular head" and the lower part the "sternal head," based on their origins from the clavicle and sternal bones, respectively. Ruptures of the pectoralis major muscle are becoming more common due to the increase in power sports weight training...

Simultaneous bilateral rupture of the distal biceps tendon is a rare clinical entity, seldom reported in the literature and with unclear therapeutic setting. The authors report the case of a 39-year-old white man who suffered a simultaneous bilateral rupture while working out. When weightlifting with elbows at 90° of flexion, he suddenly felt pain on the anterior aspect of the arms, coming for evaluation after two days. He presented bulging contour of the biceps muscle belly and ecchymosis in the antecubital fossa, extending distally to the medial aspect of the forearm, as well as a marked decrease of supination strength and pain in active elbow flexion...

A 29-year-old man experienced right shoulder pain and weakness following a forced abduction and external rotation motion performed during an Australian football game. The following morning, the sports medicine physician referred the player for magnetic resonance imaging to exclude infraspinatus rupture, given the external rotation strength deficit. Magnetic resonance imaging revealed a low-grade partial tear of the medial infraspinatus muscle. J Orthop Sports Phys Ther 2016;46(12):1087. doi:10.2519/jospt.2016...

Second anterior cruciate ligament rupture is a common and devastating injury among young women who return to sport after ACL reconstruction, but it is inadequately understood. The purpose of this study was to compare gait biomechanics and return-to-sport time frames in a matched cohort of young female athletes who, after primary ACLR, returned to sport without re-injury or sustained a second ACL injury. Approximately 6 months after primary reconstruction, 14 young women (age 16 ± 2 years) involved in jumping, cutting, and pivoting sports underwent motion analysis testing after physical therapy and impairment resolution...

Synopsis It is generally accepted that up to 50% of those with a whiplash injury following a motor vehicle collision will fail to fully recover. Twenty-five percent of these patients will demonstrate a markedly complex clinical picture that includes severe pain-related disability, sensory and motor disturbances, and psychological distress. A number of psychosocial factors have shown prognostic value for recovery following whiplash from a motor vehicle collision. To date, no management approach (eg, physical therapies, education, psychological interventions, or interdisciplinary strategies) for acute whiplash has positively influenced recovery rates...

OBJECTIVE: The purpose of this study was to analyse the incidence and characteristics of muscle injuries and hamstring muscle injuries occurred during the international athletics championships from 2007 to 2015. PATIENTS AND METHODS: National medical teams and local organizing committee physicians have collected every day all newly occurred injury whenever international championship from 2007 to 2015. Only the muscle injuries and hamstring muscle injuries, whatever gravity (cramp, contracture, rupture, avulsion), were analysed...

PURPOSE: This study aimed to prospectively investigate the association between isolated and functional lower extremity muscle strength and the risk for noncontact anterior cruciate ligament (ACL) injury in Norwegian female elite handball and football players. METHODS: From 2007 through 2015, premier league players participated in strength testing and were prospectively followed for ACL injury risk. At baseline, we recorded player demographics, playing and ACL injury history, and measured peak concentric isokinetic quadriceps and hamstring torques (60°·s), hamstring-to-quadriceps ratio, isometric hip abduction strength, and one-repetition maximum in a seated leg press...

OBJECTIVE: To present a rehabilitation exercise program and suggest a schedule of activities for daily living and participation in sports after surgical treatment of a pectoralis major rupture. DESIGN: A single case study. SETTING: Hospital-based study, Thessaloniki, Greece. PARTICIPANTS: We present a 30-year-old male athlete (height, 196 cm; weight, 90 kg; right hand dominant) with a complete rupture of the pectoralis major tendon after a fall...

BACKGROUND: The decision as to whether or not an athlete is ready to return to sport (RTS) after ACL reconstruction is difficult as the commonly used RTS criteria have not been validated. PURPOSE: To evaluate whether a set of objective discharge criteria, including muscle strength and functional tests, are associated with risk of ACL graft rupture after RTS. MATERIALS AND METHODS: 158 male professional athletes who underwent an ACL reconstruction and returned to their previous professional level of sport were included...

Isolated injuries to the teres major muscle occur in competitive sporting activities such as baseball pitching, hockey and tennis. We report a similar event of a physically fit man sustaining an isolated teres major rupture while waterskiing. Non-operative management was chosen, with pain resolution and no appreciable functional limitations at follow up. Because teres major muscle injury was suspected at the time of imaging, we present a dedicated imaging protocol to optimize assessment for teres major injury...

BackgroundThe anterior cruciate ligament (ACL) rupture accounting for about 50% of all knee ligament injuries. The rehabilitation program requires a long time to rebuild muscle strength and to reestablish joint mobility and neuromuscular control. The purpose of the study is to evaluate the muscle strength recovery in athletes with ACL reconstruction. MethodsWe enrolled soccer atlethes, with isolated anterior cruciate ligament rupture treated with bone-patellar tendon-bone autograft artroscopic reconstruction...

BACKGROUND: Patients with chronic injuries of the proximal hamstring can develop significant impairment because of weakness of the hamstring muscles, sciatic nerve compression from scar formation, or myositis ossificans. PURPOSE: To describe the surgical outcomes of patients with chronic injury of the proximal hamstrings who were treated with hamstring repair and sciatic neurolysis supplemented with nerve wrapping with acellular dermal matrix. STUDY DESIGN: Retrospective case series; Level of evidence, 4...

BACKGROUND: Rupture of the anterior cruciate ligament (ACL) is a common injury, mainly affecting young, physically active individuals. The injury is characterised by joint instability, leading to decreased activity, which can lead to poor knee-related quality of life. It is also associated with increased risk of secondary osteoarthritis of the knee. It is unclear whether stabilising the knee surgically via ACL reconstruction produces a better overall outcome than non-surgical (conservative) treatment...

The aim is to review the modalities in musculoskeletal imaging with view on the prognostic impact for the patient's and for social outcome and with view on three major fields of preventive medicine: nutrition and metabolism, sports, and patient education. The added value provided by preventive imaging is (1) to monitor bone health and body composition with a broad spectrum of biomarkers, (2) to detect and quantify variants or abnormalities of nerves, muscles, tendons, bones, and joints with a risk of overuse, rupture, or fracture, and (3) to develop radiology reports from the widely used narrative format to structured text and multimedia datasets...

BACKGROUND: Diagnosis of pectoralis major tears early in the acute phase is important for optimizing surgical repair and outcomes. However, physical examination of pectoralis major injuries can be misleading, often resulting in a potentially detrimental delay in surgical treatment. PURPOSE: To establish and validate a quantifiable clinical diagnostic test for structurally significant pectoralis major tears. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 2...
