Degloving intramuscular injuries of the semimembranosus and adductor longus muscles in adolescent soccer players.

Degloving muscle injury was described for the rectus femoris where the inner bipennate component is dissociated from its superficial unipennate component. The semimembranosus muscle displays a distinctive dual morphology, featuring both unipennate and bipennate muscle fibers. Nevertheless, this specific tear pattern has not been previously documented. Conversely, the adductor longus muscle showcases an elongated intramuscular tendon segment, indicating a multipennate morphology. We present two separate cases of previous undescribed degloving injuries of the semimembranosus and the adductor longus in teenage soccer players with MRI and ultrasound diagnosis, ultrasound-guided hematoma aspiration, and recovery timelines for return-to-play.

Management of radiology services during the 2022 FIFA football (soccer) World Cup.

Diagnostic imaging is the predominant medical service sought for the assessment and staging of musculoskeletal injuries in professional sports events. During the 2022 FIFA Football (soccer) World Cup, a centralized medical care infrastructure was established. This article provides a comprehensive account of the radiological services implemented during this event, encompassing the deployment of equipment and human resources, the structuring of workflows to uphold athlete confidentiality, and initiatives aimed at enhancing communication. Communication channels were refined through radiology consultations held with national teams' health care providers and the adoption of audiovisual reports available in multiple languages, which could be accessed remotely by team physicians. Our established framework can be replicated in international professional football events for seamless integration and efficacy.

Imaging-detected sports injuries and imaging-guided interventions in athletes during the 2022 FIFA football (soccer) World Cup.

OBJECTIVE: To describe imaging-detected musculoskeletal injuries and image-guided interventional procedures during the 2022 FIFA football (soccer) World Cup. MATERIALS AND METHODS: Retrospective analysis of all radiologic examinations performed in a central medical facility for athletes was performed by two board certified musculoskeletal radiologists. Data on muscle, tendon, ligament, cartilage, and bone injuries were collected according to imaging modality and body part. RESULTS: A total of 143 radiology examinations in 94 athletes were evaluated at the central medical facility. Magnetic resonance imaging (MRI) was the most utilized modality (67%), followed by radiography (12%), ultrasonography (9%), and computed tomography (4%). Image-guided interventions corresponded to 8% of all radiological examinations. There were 112 injuries described, affecting muscles and tendons (42%), ligaments (25%), cartilage (21%), and bone (12%). Most injured body parts were thigh (27%), foot and ankle (23%), knee (23%), and hip/groin (8%). Most injured players were within the age range of 24-35 years old (71%). CONCLUSION: Imaging was utilized in 11% of players who participated in the 2022 FIFA World Cup in Qatar. MRI was the most utilized modality, and acute muscle tears were the most diagnosed type of injury. Diagnostic imaging played an important role in diagnosing sports-related injuries during the 2022 FIFA World Cup.

Medical services at the FIFA world cup Qatar 2022.

OBJECTIVE: The Football World Cup is among the biggest sporting events in the world, but data to inform the requirements of medical care for such tournaments are limited. This study describes the athlete and team medical services at the FIFA World Cup Qatar 2022 . METHODS: Three different medical service entities were identified through a needs analysis based on expert advice, team physician interviews and questionnaires prior to the event: 'Team Services' to provide any workforce or equipment needs of the teams, a 'Polyclinic' to manage any acute medical demands, and a 'recovery centre' to improve game readiness throughout the tournament. All services had been set up prior to the tournament and thoroughly tested. RESULTS: Of a total of 832 athletes, ~1300 team delegation and ~130 match officials, 167 individuals including 129 (77%) athletes and 38 (23%) non-athletes were assessed in the polyclinic. For the 129 athletes (median 4 players per team), medical imaging was the most requested service, which peaked during the group phase of the tournament. Most requests were received during normal working hours despite many games finishing late at night. 30 of the 32 participating teams solicited medical services for their players at least once. Three teams made use of the recovery facilities, and 17 teams requested additional medical equipment or clinical assistance. CONCLUSION: Central imaging services was the most used medical resource at the FIFA World Cup Qatar 2022, and over half of teams required additional medical equipment or personnel. These data may inform planning of medical services for similar events in the future.

High-resolution Ultrasound of the Foot and Ankle.

High-resolution ultrasound (US) can be used to assess soft tissue abnormalities in the foot and ankle. Compared to MRI, it has lower cost, is widely available, allows portability and dynamic assessment. US is an excellent method to evaluate foot and ankle tendon injuries, ligament tears, plantar fascia, peripheral nerves, and the different causes of metatarsalgia.

Imaging of Muscle Injuries: MR Imaging-Ultrasound Correlation.

Ultrasound (US) and MR imaging are the most common imaging modalities used to assess sports muscle injuries. The site of the muscle injury can be located at the peripheral aspect of the muscle (myofascial), within the muscle belly (musculotendinous), and with tendon involvement (intratendinous). Tears that affect the intramuscular tendon have a worse prognosis in terms of recovery time. US is an excellent method to evaluate muscle injuries, with high spatial and contrast resolution. MR imaging can be reserved for evaluation of professional athletes, surgical planning, differential diagnosis, and assessment of deep located and proximal muscle groups.

Management of desmoid-type fibromatosis involving peripheral nerves.

Desmoid-type fibromatosis is an uncommon and aggressive neoplasia, associated with a high rate of recurrence. It is characterized by an infiltrative but benign fibroblastic proliferation occurring within the deep soft tissues. There is no consensus about the treatment of those tumors. We present a surgical series of four cases, involving the brachial plexus (two cases), the median nerve and the medial brachial cutaneous nerve. Except for the last case, they were submitted to multiple surgical procedures and showed repeated recurrences. The diagnosis, the different ways of treatment and the prognosis of these tumoral lesions are discussed. Our results support the indication of radical surgery followed by radiotherapy as probably one of the best ways to treat those controversial lesions.

A fibromatose do tipo desmoide é uma lesão tumoral agressiva e rara, associada a alto índice de recorrência. É caracterizada pela fibroblástica infiltrativa, porém benigna, que ocorre no interior de tecidos moles profundos. Não existe consenso com relação ao tratamento desses tumores. Apresentamos uma série cirúrgica de quatro casos comprometendo o plexo braquial (dois casos), o nervo mediano e o nervo cutâneo medial do braço. Com exceção do último caso, todos foram submetidos a múltiplos procedimentos cirúrgicos e apresentaram recorrências repetidas. São discutidos o diagnóstico, as diferentes formas de tratamento e o prognóstico dessas lesões tumorais. Nossos resultados apoiam o conceito de que cirurgia radical seguida por radioterapia é uma das melhores formas de se tratar essas controvertidas lesões.

Estado atual do "split-lever" como opcao tecnica para o transplante de figado: revisao da literatura / An update of split liver as a technical option of liver transplantation: review of literature

A falta de doadores de orgaos e um fator critico que limita o emprego do transplante ortotopico de figado em nosso meio. O "split-liver" refere-se a seccao regrada do figado de um doador para implante em dois receptores. Os autores revisaram a literatura e observaram que apesar desta tecnica possuir indices de complicacoes pos-operatorias e mortalidade superiores ao transplante habitual constitui-se em boa opcao tecnica para pacientes cronicamente em listas de espera bem como aqueles com insuficiencia hepatica aguda e subaguda que necessitam de um novo orgao para manterem-se vivos.
