Diagnosis and treatment of chronic exertional compartment syndrome of the lower extremities: a review / 中华创伤杂志

Chronic exertional compartment syndrome (CECS) of the lower extremities is a common clinical condition characterized by exercise-induced pain in the extremities, which is predominantly observed in people who take an active part in sports, such as athletes. It is mainly presented as post-exercise pain in the lower extremities, probably accompanied by numbness and limb weakness, etc., affecting the patients′ life and work. The symptoms of CECS in the lower limbs are usually present after physical activities of a certain intensity, making them difficult to be identified through routine outpatient physical examination, and likely to be misdiagnosed and underdiagnosed. Furthermore, the absence of universally accepted and unified treatment standards for CECS of the lower extremities complicates the decision-making process regarding the necessity of surgical intervention and choice of surgical approach in the clinical practice. For this purpose, recent developments in the diagnosis and treatment of CECS of the lower extremities were reviewed to provide reference for its standardized diagnosis and treatment.

Application of platelet-rich plasma-based regenerative rehabilitation technology in the management of sports injury / 中华创伤杂志

The most common sports injury is trauma to the skeletal muscles, with injuries to ligaments, muscles, tendons, joint capsules or cartilage and minor injuries to other chronic soft tissues, accounting for 97% of all cases. These injuries directly affect athletes′ performance, shorten their athletic career, and also impede the daily life and work of the general public. Surgical and non-surgical interventions often fail to meet the demands for quick recovery, and patients with sports injury may experience joint stiffness, limited range of motion, and pain-related functional impairments. Platelet-rich plasma (PRP) has a role in the promotion of tissne regeneration, regulation of immune response and suppression of inflammation. PRP-based regenerative rehabilitation technology offers new possibilities for rapid recovery of patients with sports injury. However, there have been few reports on the combined application of PRP and principles/methods of rehabilitation medicine. To this end, the authors summarized the history of regenerative rehabilitation medicine, explored the feasibility of PRP-based regenerative rehabilitation technology in the treatment of sports injuries, and discussed the application prospects of PRP-based regenerative rehabilitation technology regarding the joint, muscle, tendon, and ligament injuries.

Application value of joint friction sounds in diagnosing meniscus injury of the knee based on machine learning models / 中华创伤杂志

Objective:To investigate the application value of joint friction sounds in diagnosing meniscus injury of the knee based on machine learning models.Methods:A case-control study was conducted to analyze the clinical data of 17 patients with meniscus injury of the knee (meniscus injury group) admitted to Sir Run Run Shaw Hospital Affiliated to Nanjing Medical University from August 2020 to October 2022, as well as 75 recruited healthy subjects without knee joint diseases (healthy group). The knee joint friction sounds of the subjects were collected in a relatively quiet environment (peak value below 40 dB). The sounds collected in a flexion-extension-flexion mode of exercise were split and divided randomly with a ratio of 4∶1 into the training set (125 segments from the meniscal injury group and 187 segments from the healthy group) and the test set (33 segments from the meniscal injury group and 47 segments from the healthy group). The sounds obtained in a sit-stand-sit mode of exercise were split and divided randomly with a ratio of 4∶1 into the training set (81 segments from the meniscal injury group and 164 segments from the healthy group) and the test set (20 segments from the meniscal injury group and 40 segments from the healthy group). Four machine learning models were built, including support vector machine with linear kernels, radial basis function support vector machine, random forest, and extremely randomized trees. The learning training of the model was performed on the training set, and its model performance was verified with the test set. The time required in a single collection of joint friction sound from the subjects and the interpretation of data analysis was recorded. Knee function of the subjects were scored according to the Lysholm Score before and at 1 day after the test. The accuracy rates of diagnosis of meniscus injury with friction sounds under the two modes of exercise were compared based on the test results to yield an optimal one. The effectiveness of the four models was compared to find the best machine learning model fitting the data frame of this study according to the test results such as accuracy, sensitivity, specificity, F1 score, and area under the receiver operating characteristic curve (AUC) obtained with the optimal mode of exercise. The diagnostic accuracy, misdiagnosis rate and missed diagnosis rate of joint friction sound for meniscal injury under the optimal machine learning model with the optimal mode of exercise were observed.Results:The time required in a single collection of joint friction sound ranged from 5 to 10 minutes [(7.1±1.3)minutes], when the time required for interpretation of data analysis was approximately 1 minute. The Lysholm Score before and after the test was (75.6±4.0)points and (77.7±3.7)points respectively in the meniscal injury group ( P>0.05), and (99.6±0.9)points and (99.5±1.0)points respectively in the healthy group ( P>0.05). The diagnosing accuracy rates for flexion-extension-flexion of exercise and sit-stand-sit modes of exercise were 0.775 and 0.817 under the support vector machine model with linear kernels; 0.813 and 0.900 under the radial basis function support vector machine model; 0.800 and 0.867 under the random forest model; 0.800 and 0.900 under the extremely randomized tree model. The accuracy rates for sit-stand-sit mode of exercise were all higher than those for flexion-extension-flexion mode of exercise. In the sit-stand-sit mode of exercise, the extremely randomized tree model had an accuracy rate of 0.900, sensitivity of 0.900, specificity of 0.950, F1 score of 0.900, and AUC of 0.942, which were higher than those under the remaining 3 models, showing better machine learning efficacy. Under the extremely randomized tree model in the sit-stand-sit mode of exercise, 22 (18 true positive and 4 false positive) were diagnosed as meniscal injury and 38 (36 true negative and 2 false negative) as healthy out of 60 segments in the test set (20 from the meniscal injury group and 40 from the healthy group). The diagnostic accuracy of joint friction sounds in diagnosing meniscus injury of the knee was 0.900, with the misdiagnosis rate of 0.100 and the missed diagnosis rate of 0.100. Conclusion:Diagnosis of meniscus injury of the knee with joint friction sounds can shorten time and enhance safety during the examination process. The diagnostic model using machine learning-based artificial intelligence is faster and more stable, which can be used as a diagnostic marker for such injury.

Comparison of platelet-rich plasma and sodium hyaluronate in treatment of rotator cuff injury / 中华创伤骨科杂志

Objective:To compare the clinical effects of platelet-rich plasma (PRP) and sodium hyaluronate on rotator cuff injury.Methods:From February 2022 to December 2022, 226 patients with rotator cuff injury caused by military training were treated at Department of Orthopaedics, Jinling Hospital, School of Medicine, Nanjing University. They were all male, aged (24.5±3.7) years, and their time from injury to treatment was (4.6±2.2) months. They were divided into 2 even groups according to different treatments: an observation group of 113 cases into whose subacromial space PRP was injected, and a control group of 113 cases into whose subacromial space sodium hyaluronate was injected. In both groups, the injection was performed once a week for consecutive 3 weeks. The 2 groups were compared in terms of visual analogue scale (VAS) and Constant-Murley shoulder function scale (CMS) before treatment and 4 and 8 weeks after treatment, and the levels of TNF- α and IL-6 in the shoulder synovial fluid before treatment and 8 weeks after treatment. Results:There was no statistical difference between the 2 groups in general clinical data before treatment, indicating comparability ( P>0.05). At 4 and 8 weeks after treatment, compared with the pre-treatment values, the VAS scores were significantly decreased and the Constant-Murley scores significantly increased in both groups ( P<0.001). At 4 and 8 weeks after treatment, the VAS scores in the observation group (3.1±0.9 and 1.5±0.5) were significantly lower than those in the control group (3.7±0.8 and 2.3±0.6) while the Constant-Murley scores in the observation group (58.6±4.5 and 72.2±4.1) significantly higher than those in the control group (55.2±5.3 and 67.8±5.0) ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the 2 groups were significantly lower than the levels before treatment ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the observation group [(2.9±0.9) μg/L and (0.8±0.2) μg/L] were significantly lower than those in the control group [(4.0±0.4) μg/L and (1.1±0.4) μg/L] ( P<0.001). Conclusion:Injection of PRP or sodium hyaluronate can relieve pain and improve shoulder function obviously in patients with rotator cuff injury, but PRP is superior to sodium hyaluronate in the treatment of rotator cuff injury.

Characteristics and treatment of snow sports injuries in Zhangjiakou Zone of the Olympic Winter Games Beijing 2022 / 中华创伤骨科杂志

Objective:To characterize the injuries suffered by athletes in snow events other than alpine skiing in the Zhangjiakou Zone of the Olympic Winter Games Beijing 2022, in order to provide insights for prevention of sports injuries and preparation of large-scale winter sports events.Methods:The medical records were retrospectively collected of all athletes who had been treated at Beijing University Third Hospital Chongli within the closed loop of the Zhangjiakou Zone during the Winter Olympics and Paralympics (from November 21, 2021 to April 5, 2022). The incidence, severity and part of the injuries were analyzed, as well as the medical treatment process.Results:In the Zhangjiakou Zone, a total of 1,188 athletes participated in the Winter Olympic Games, with an injury incidence of 2.9% (34/1,188), while 420 ones participated in the Winter Paralympic Games, with an injury incidence of 1.7% (7/420). The average daily medical visits were the highest during the Winter Olympics phase (1.16 visits per day), and their emergency severity index (ESI) ranged from level 3 to level 4. The department of orthopedics was visited the most (92.7%, 38/41). Lower limb injuries accounted for the highest proportion (53.7%, 22/41), with the knee ones accounting for 36.6% (15/41) of all injuries. Most of the athletes with ESI level 3 received splint fixation (62.5%, 5/8), while those with ESI level 4 mostly received observation and follow-up (57.6%, 19/33). A total of 57 radiological examinations were performed in the 41 athletes. X-ray was used the most frequently on a single day (5.00 times) while magnetic resonance imaging was per day on average (0.16 times). The transfer time for the athletes injured was (27.4±8.8) min which was not influenced by the 4 weather conditions (cloudy, sunny, light snow, and cloudy) ( P=0.374). Conclusions:The incidence of injuries during the Beijing Winter Olympics in the Zhangjiakou Zone was lower than that in other areas of the Beijing Winter Olympics and in previous Winter Olympics. There were no serious life-threatening cases. The imaging examination resources and transfer speed in the Zhangjiakou Zone were able to meet the medical needs of athletes at all stages of the Beijing Winter Olympics and Paralympics. Athletes should pay attention to protection of their lower limbs during skiing competitions.

Characteristics of severe sports injuries related to alpine skiing during the 2022 Winter Olympics and Paralympics in Beijing / 中华创伤骨科杂志

Objective:To characterize the severe sports injuries related to alpine skiing during the 2022 Beijing Winter Olympics and Paralympics so as to provide information for the prevention and treatment of sports injuries in the Yanqing National Alpine Skiing Center tracks.Methods:The medical data were collected of all the alpine skiing athletes and related staff who had sought medical treatment in Peking University Third Hospital Yanqing Hospital during January 20, 2022 to March 26, 2022. Descriptive statistical analyses were conducted for body part, type, occurrence place, and severity of the injuries.Results:There were 49 patients who had suffered severe injuries related to alpine skiing events during this Olympic Games, with 68 injuries by body parts and 72 injuries by types. The most common injury part was the knee (25.0%, 17/68), followed by the head (14.7%, 10/68), and the shoulder (8.8%, 6/68). The most common types of injury were contusion (including hematoma and abrasion, 30.6%, 22/72), followed by sprain (including dislocation, subluxation, and ligament injury, 22.2%, 16/72), and fracture (20.8%, 15/72). The most common occurrence place in the tracks for athletes was the "Haituo Bowl" area (41.7%, 10/24). In terms of severity, the injuries led to an absence from training or competition in 48 athletes [98.0% (48/49)], of whom 33 were severely injured [67.3% (33/49)].Conclusions:The most vulnerable part for severe sports injuries in the alpine skiing events of the 2022 Beijing Winter Olympics and Paralympics was the knee, mostly with ligament injuries, which is consistent with the findings of previous events. The high proportion of severe injuries indicated the difficulty of this track. The place where injuries mostly occurred was the "Haituo Bowl" area of the racing track, also the most challenging part of this track, indicating a necessity of more medical resources in this area.

Clinical characteristics and treatment of 147 patients with winter ice and snow sports injuries in Xinjiang / 中华创伤骨科杂志

Objective:To analyze the clinical characteristics and treatment methods of the patients who suffered from ice and snow sports injuries in Xinjiang in winter so that useful information can be provided for medical service for ice and snow sports.Methods:A retrospective study was conducted to analyze the clinical data of 147 patients who had sought medical attention for ice and snow sports injuries at Department of Orthopaedics, Xinjiang Uygur Autonomous Region Hospital of Traditional Chinese Medicine from November 2018 to March 2022. The basic information, injury site, injury type, injury cause, length of hospitalization, and treatment methods of the patients were classified and statistically analyzed. The χ2 test was used to compare the injury site and type in patients of different ages, and the nonparametric Kruskal-Wallis test to compare the length of hospitalization in patients of different ages. Results:Of the 147 patients, 73 were males and 74 females with an age of (27.8±15.6) years. The top 3 injury sites were the lower limb (36.91%, 55/149), the upper limb (31.54%, 47/149), and the head and face (14.77%, 22/149). The top 3 injury types were fractures (61.90%, 91/147), skin and soft tissue lesions (14.97%, 22/147), and ligament lesions (10.20%, 15/147). The main causes for injury were fall (58.50%, 86/147), sprain (20.41%, 30/147), and bruise (19.73%, 29/147). Of the 91 patients with fractures, 55 (60.44%, 55/91) underwent surgical treatment, and 32 (35.16%, 32/91) closed reduction and plaster/brace external fixation. Eight of the 22 patients with soft tissue lesions (36.36%, 8/22) and 7 of the 15 patients with ligament lesions (46.67%, 7/15) underwent surgical treatment. The length of hospitalization for the 147 patients was 6.0 (4.0, 9.0) d. The differences in injury site and injury type were statistically significant between different age groups of patients, and the length of hospitalization was significantly different between different age groups of fracture patients ( P<0.05). Conclusions:Young people are the population who suffered from the most injuries due to ice and snow sports in winter in Xinjiang. Injury sites, injury types, and lengths of hospitalization varied with different age groups. Fractures were the most common type of injury. The participants of ice and snow sports should be fully aware that ice and snow sports are highly risky and thus avoid high-risk movements. Doctors should consider the patient's age, injury site, and injury type comprehensively when they formulate specific diagnostic and treatment schemes.

Characteristics of major sports injuries in high-performance athletes / Características das principais lesões esportivas em atletas de alto desempenho / Características de las principales lesiones deportivas en atletas de alto rendimiento

ABSTRACT Introduction The focus of attention in high-performance athlete injuries tends to be on physical recovery, neglecting psychological factors and their practical social impacts on the rehabilitation of the injured athlete. In this phase, giving attention to the importance of athletes' thoughts, emotions, and motivation can speed up the biopsychosocial rehabilitation process. Objective To analyze the characteristics involved in the major sports injuries of high-level athletes to provide a reference for athletes and coaches during recovery. Methods This article analyzes through bibliographic research the characteristics of the major sports injuries in high-level athletes, including physiological, psychological, and social factors. Results The physical impact of injuries requires patience and persistence for recovery, including additional muscle strengthening to compensate for the loss of residual joint proprioception, ensuring performance recovery. Mental factors such as insecurity when returning from games, reduced self-confidence, and fear of hurting the team must be worked through in parallel in multi-professional care and during long recovery periods. Conclusion Sports injuries can occur in athletes of all levels. For elite athletes, the impact of injuries, especially severe ones that need to interrupt training or even surgery, will lead to forced suspension of training or competition, preventing the improvement of sports performance, decreasing the quality of the sports career, and may even lead to physical or psychological disability in severe cases. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Resultados As principais formas de lesões esportivas graves causadas pelos tenistas foram lesões agudas e moderadas. As fraturas mais comuns que ocorrem são principalmente as ligamentares e tendinosas: lesão ou laceração do ligamento articular, lesão ligamentar muscular, bursite e contusão ligamentar de tecidos moles. As articulações mais envolvidas são joelhos, tornozelos, cotovelos, pulsos e ombros. Conclusão As causas comuns das lesões esportivas nos tenistas são uma união de imprecisão dos movimentos técnicos, atividades de força muscular insuficientes e força insuficiente para atividades técnicas preparatórias. Na prática, recomenda-se aos atletas corrigir e padronizar seus movimentos. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.
