Flexor carpi radialis (FCR) muscle is located in the forearm anteriorly that runs through a synovial fibro-osseous tunnel in the forearm. We described a case of FCR tendon rupture due to repetitive overuse injury. A 55-year-old man, right-hand dominant, presented with right forearm pain and swelling which started 3 days ago while playing amateur golf. Focal tenderness and bruising over volo-ulnar region of the right forearm were examined. Plain radiographs showed soft tissue edema around lesion area and no detectable fracture. Ultrasonography showed multiple hypoechoic lesions suspected as hematoma of the flexor muscle group. After done magnetic resonance imaging, he was diagnosed with rupture of FCR tendon at proximal origin and strain of flexor digitorum superficialis and palmaris longus muscle. He received compressive dressing and restriction of wrist range of motion for three weeks. Two months later, remaining traces of lesions were observed at the follow-up ultrasonography and the pain disappeared.

Medial epicondylitis, also known as “golfer's elbow,” is a common overuse syndrome of the elbow and predominantly affects the origin of the common flexor tendon. We report two unique cases of medial epicondylitis complicated by chronic complete tear of the ulnar collateral ligament and common flexor tendon origin. Physical examination showed a focal huge swelling of medial epicondylar region of the dominant elbow and magnetic resonance imaging revealed complete tear of the ulnar collateral ligament and common flexor tendon and extravasation of intra-articular effusion. Satisfactory results were achieved with ulnar collateral ligament reconstruction and simultaneous repair of the common flexor tendon origin.

PURPOSE: To investigate the prevalence and risk factors of musculoskeletal disorder (MSD) among spine surgeons. MATERIALS AND METHODS: A modified version of discomfort survey was sent via e-mail to surgeons that belong to the Korean Society of Spine Surgery. The survey questionnaires were composed of demographics, factors relating to spine surgery, and MSD. We investigated the common sites of occurrence of MSD and its risk factors. RESULTS: The survey was sent to a total of 420 subjects; of which, 80 subjects (19.0%) responded. About 78.8% of the respondents had MSD for the past year. The common sites of occurrence included the neck (52.5%), back (46.3%), and shoulder (18.8%). The prevalence of pain in the elbow joint/forearm was higher in the group performing a higher frequency of spine surgeries (p=0.033). Moreover, the prevalence of pain in the wrist/hand (p=0.008) and in the back (p=0.042) was higher in those with greater frequency of major surgeries (>10 case/year) as compared with those with lower frequency of major surgeries. CONCLUSION: As shown, about 78.8% of spine surgeons experienced MSD for the past one year. Its prevalence was higher as compared with the general population. Thus, more attention should be paid to the prevention of MSD among spine surgeons.

Capsuloligamentous injury at the first metatarsophalangeal (MTP) joint is a common traumatic injury during physical activity, particularly on artificial turf. Mechanism of injury include excessive flexion, extension, or valgus stress. We report a non-operatively treated capsuloligamentous injury at the first MTP joint, which did not occur traumatically but developed by a stress-related mechanism in a collegiate rower.

Iliotibial band (ITB) friction syndrome is a common overuse injury typically seen in the active athlete population. A nodular lesion on the inner side of the ITB as an etiology or an accompanying lesion from friction syndrome has been rarely reported. A 45-year-old male presented with recurrent pain and a movable nodule at the lateral joint area, diagnosed as ITB friction syndrome. The nodule was confirmed as a rare intra-articular fibroma of the tendon sheath (FTS) on the basis of histopathologic findings. We describe the MRI findings, arthroscopic and pathologic features, in this case of intra-articular FTS presenting with ITB friction syndrome.

OBJECTIVEIn this study, we aimed at exploring the association between work-related musculoskeletal disorders (WMSDs) and work organization based on a case-control study.

METHODSA total of 1938 workers who claimed to suffer from WMSDs were selected from Beijing, Henan, Hubei, and the Guangdong province. The control group consisted of 2009 workers employed in similar industries without severe disease or musculoskeletal discomforts. We used a modified version of the questionnaire developed by the NMQ and the DMQ to investigate individual and work-related factors.

RESULTSA total of 13 variables (P<0.1) were selected by the chi-square test and finally, 7 variables entered into the equation, with 6 variables reaching statistical significance (P<0.05). The odds ratios (OR) of 'work changing with season' and 'sufficient rest time' did not reach 1 (0.749 and 0.441, respectively). In addition, 'sufficient rest time' seemed to be the stronger protective factor according to its higher standardized coefficient. And 'repetitive work every minute', 'constantly repetitive work' (every day), 'shortage of site personnel', and 'often switching shifts with others' seemed to be the risk factors.

CONCLUSIONWork organization may have comprehensive effects on the occurrence of WMSDs. This pattern of associations suggests that further investigation into the mechanism of how work organization affects the prevalence of WMSDs is required.

The purpose of this study is to evaluate the risk factors regarding the injuries from sports climbing through an epidemiologic study. We performed a questionnaire survey on sports climbers who participated in the 93th Annual Sports Festival in Daegu, in October 2012. Sixty-nine climbers (male: 57, female: 12) responded to the survey. The t-test was used for comparisons of the incidence of injury, according to sex and career. The multiple linear regression analysis and the logistic regression analysis were used for the evaluation of risk factors that affected the occurrence of injury. Overall, 58 (84.06%) climbers had history of injury. The incidences of climbing related injuries were higher than the incidences of cross-training related injuries. However, there were no significant difference (p=0.680). Also, there was no significant difference between males and females (p=0.467), and professionals and amateurs (p=0.076). Fifty (72.46%) out of 69 climbers had history of traumatic injuries, and 40 (57.97%) climbers had history of overuse injuries. Significant risk factors for traumatic injuries are leading (odds ratio, OR=17.854), speed (OR=45.246), and bouldering (OR=13.595). Significant risk factors for overuse injuries are leading (OR=23.252) and bouldering (OR=41.260). Significant risk factors for middle phalanx injuries, which happens most frequently in climbing related injuries, are leading (OR=20.625) and bouldering (OR=25.756). For traumatic injuries, leading, speed, and bouldering are prone to cause injuries, and leading and bouldering are significant factors for overuse injuries. Therefore, it is considered that the systematic organized training can help reduce the incidence of injury.

OBJECTIVES: The aim of this study was to evaluate musculoskeletal and psychosocial perception and compare these conditions regarding the type of job (white or blue-collar) and the type of management model (private or public). METHODS: Forty-seven public white-collar (PuWC), 84 private white-collar (PrWC) and 83 blue-collar workers (PrBC) were evaluated. Job Content Questionnaire (JCQ) and Utrecht Work Engagement Scale (UWES) were applied to evaluate psychosocial factors. Nordic Musculoskeletal Questionnaire (NMQ) was used to assess musculoskeletal symptoms. Pressure Pain Threshold (PPT) was measured to evaluate sensory responses. RESULTS: According to JCQ, all groups were classified as active profile. There was a significant association between work engagement and workers' categories (p < 0.05). PrWC workers had the highest scores for all the UWES domains, while PrBC had the lowest ones. PPT showed that PrBC workers had an increased sensitivity for left deltoid (p < 0.01), and for both epicondyles (p < 0.01), when compared to the other groups. PrWC workers had an increased sensitivity for both epicondyles than PuWC (right p < 0.01; left, p = 0.05). There was no significant association in the report of symptoms across the groups (p > 0.05). CONCLUSION: This study showed differences in psychosocial risk factors and musculoskeletal symptoms in workers engaged in different types of jobs and work organization. Personal and work-related characteristics, psychosocial factors and PPT responses were different across workers' group. Despite all, there was no significant difference in reported symptoms across the groups, possibly indicating that the physical load is similar among the sectors.

There is increasing attention to medical problems of musicians. Many studies find a high prevalence of work-related musculoskeletal disorders in musicians, ranging from 73.4% to 87.7%, and string players have the highest prevalence of musculoskeletal problems. This paper examines the various positions and movements of the upper extremities in string players: 1) basic postures for holding instruments, 2) movements of left upper extremity: fingering, forearm posture, high position and vibrato, 3) movements of right upper extremity: bowing, bow angles, pizzicato and other bowing techniques. These isotonic and isometric movements can lead to musculoskeletal problems in musicians. We reviewed orthopedic disorders that are specific to string players: overuse syndrome, muscle-tendon syndrome, focal dystonia, hypermobility syndrome, and compressive neuropathy. Symptoms, interrelationships with musical performances, diagnosis and treatment of these problems were then discussed.

The purposes of this study were basic data collection and evaluation of the risk factors regarding rowing injuries through an epidemiologic study. We performed a questionnaire survey from rowers who participated in the 91th Annual Sports Festival in Jinju, Gyeongnam, in October 2010. 145 rowers (male: 84, female: 61) responded to the survey. The t-test was used for comparisons for the type of injury, age, and gender. The multiple linear regression analysis and the logistic regression analysis was used for the evaluation of risk factors. Overall, 100 (69.0%) rowers had a history of injury. The incidence of overuse injuries was significantly higher than the incidence of traumatic injuries (2.07+/-2.59/rower vs. 1.46+/-2.08/rower, p=0.027). The incidence of injuries for the adult group was significantly higher than those in the youth group (4.42+/-4.45/rower vs. 2.61+/-3.63/rower, p=0.008). There was no significant difference between males and females (3.85+/-4.33/rower vs. 3.08+/-3.87/rower, p=0.275). Also, the incidence of cross-training related injury was significantly higher in traumatic injuries rather than in overuse injuries (0.92+/-1.54/rower vs. 0.5+/-1.07/rower, p=0.008). In addition, rowing injuries were more related with overuse injuries. Risk factors regarding overall rowing injuries were training time, and training using stairs. Traumatic injuries were related with diverse cross-training and time spent cross-training. Therefore, in order to reduce the incidence of rowing injuries, time and the number of cross-training sessions should be reduced. Moreover, highly risky training such as using stairs should be replaced with other low risk training methods.
