Iatrogenic damage of the rotator cuff followed by postoperative shoulder function loss is a potential complication after antegrade intramedullary nailing (AIN) for a humeral fracture. The authors present a case of arthroscopic rotator cuff repair and subacromial decompression of a non-healed rotator cuff tendon (mainly supraspinatus) and secondary impingement syndrome caused either by the tear or a proud nail after AIN for a mid-shaft humeral fracture. At presentation, the patient complained of right shoulder pain and 'snapping', especially during forward elevation and abduction of the shoulder, of 4 years duration. Right shoulder pain started sometime after pain due to the humeral shaft fracture, operation had subsided, and persisted after nail removal. Arthroscopic findings showed a longitudinal rotator cuff tear at the nail entry point that had not healed and severe fibrous hypertrophy on the acromion underspace, which is a unique finding since most longitudinal splits of tendon fibers are more likely to heal than conventional rotator cuff tears detached from bone. The torn rotator cuff was repaired after debridement and placing side-to-side sutures. At his 34-month follow-up after rotator cuff repair, the patient showed complete recovery and had excellent clinical scores.

The elbow is the most frequent area of complaint in children and adolescent baseball players. The physical stresses associated with repetitive throwing create extra-ordinary forces, which may affect the normal osteochondral and soft tissue developmental process and are the important factors causing the decrease of competitive power and shortening of life as a baseball player in adolescents. We surveyed the 114 baseball players of middle & high school in Taegu in order to evaluate the prevalance of symptoms and radiologic findings of the elbow and correlation of these findings to career & position of the baseball game. The results were as follows. 1. Of 114 players, 83 were non-pitchers and 31 were pitchers. The mean career was 3.8 years (7 months to 6 years). 2. The 77 players (67.7%) had the pain on their elbow during or after daily exercise. Other clinical symptoms were locking (30.7%), limitation of motion (18.4%), swelling (16.6%) and clicks on motion (10.5%). 3. On the radiogram of the elbow, hypertrophy or separation of medial epicondyle were seen in 34% of players, loose bodies in 17%, hypertrophy of the humerus in 12% and cystic change of the capitellum in 11%. 4. The mean career of symptomatic players was 4.4 years but non-symptomatics was 2.7 years. The mean career of players who had abnormal radiologic findings was 5.1 years but 3.1 years in players who had no abnormal radiologic fingings. 5. Symptoms and pathologic changes were more common in the elbow of pitcher' s group due to throwing frequency & pitching style. 6. Among the 77 players who had any kinds of problem of the elbow, 49 players of them had no experience of visiting hospital. 7. To prevent these injuries of the elbow, the following recommendations were made. First, restrict the number of innings pitched per game. Second, avoid throwing the curve ball in this age group. Third, ensue an adequate warm up period before exercise or rest after games. Fourth, inform parents and coaches of possible harmful nature of excessive throwing.

4.Epidemiology and etiology of shoulder pain based on health statistics data from Healthcare Bigdata Hub in Korea
Journal of the Korean Medical Association 2022;65(11):687-698
The study investigated the current epidemiologic and etiologic trends of shoulder pain over the past 10 years in South Korea.Current Concepts: From 2011 to 2020, nationwide health statistics data of the following diseases and soft tissue damage codes related to shoulder pain were extracted from the Healthcare Bigdata Hub—M75, S43, and S46. The annual changes in total medical cost and the number of patients with the three codes were extracted. The crude and age-standardized prevalence rates, and the annual percentage change were analyzed to characterize trends in prevalence rates over time. Changes in the proportion of medical cost by age, hospital type, and outpatient/inpatient distribution were also analyzed. Among the three codes, a significant increase in total medical cost, crude and age-standardized prevalence was observed only for the code M75. Additionally, in the distribution of total medical cost for the code M75 by age, the increase in the number of patients of the age group of 60 to 69 years was remarkable. The total medical cost gradually decreased at the clinic level and showed a remarkably increasing trend at the hospital level. This pattern is consistent with those of rotator cuff disease (M751), a representative disease of shoulder lesions.Discussion and Conclusion: The age of patients with shoulder pain appears to be increasing. Considering this trend of change in health statistics on shoulder pain in Korea, socioeconomic support and improvement of health policy regarding the distribution of medical expenses and resources for shoulder pain will be more necessary in the future.

PURPOSE: The objective of this study was to assess myocardial function before and after IVIG treatment by tissue Doppler imaging in children with Kawasaki disease. METHODS: This study was conducted on 43 patients with Kawasaki disease from April 2005 to February 2006 at Dongsan Medical Center, Keimyung University. Myocardial function of all patients was examined using echocardiography before (time 1) and after intravenous gamma-globulin (IVGG, time 2) treatment. Deceleration time (DT), isovolumic relaxation time (IVRT), fractional shortening (FS), and peak early diastolic (E), peak late diastolic (A) velocity of transmitral flow were measured by M-mode and pulsed wave Doppler. Systolic (Sm), peak early diastolic (Em), peak late diastolic (Am) velocity in apical 4-chamber and 2-chamber views were measured by tissue Doppler imaging. The author calculated modified Tei index, E/A, E/Em ratio by using measured values. RESULTS: Forty three patients were 27 boys and 16 girls. The average age of patients was 3 years and 1 month. There was 5 patients treated IVGG more than twice and no patient with definite coronary dilatation. All conventional Doppler parameters showed no significant difference statistically between control and time 1, 2. Among tissue Doppler parameters measured at time 2 in comparison to control and time 1, modified Tei index in septum, E/Em and modified Tei index in inferior wall decreased significantly and Am in inferior wall increased significantly. CONCLUSION: Although the results did not show consistency throughout all measured areas, it showed significant difference between patients and control in some areas' myocardiac function in relative recovery phase. This results are thought that the change in myocardial function may be derived from the Kawasaki disease during acute phase and recovery phase. There should be more investigations both in number and in diversity of patients with Kawasaki disease and there also should be studies to find how the changes mentioned above are different from persistent febrile group without the Kawasaki disease and whether they are temporal changes in the acute phase due to IVIG volumic overload.

BACKGROUND: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. METHODS: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. RESULTS: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder (8.2 +/- 7.9 mm versus 7.3 +/- 3.4 mm, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal. CONCLUSIONS: In cases of an unstable distal clavicle fracture with coracoclavicular ligament disruption, satisfactory clinical results were obtained by locking plate fixation and coracoclavicular ligament suture augmentation concurrently.

The Journal of the Korean Orthopaedic Association 2022;57(3):213-222
Purpose:
This study examined the characteristics based on the ultrasound findings of non-contact, gradual-onset shoulder pain in recreational-level surf beginners with a surf experience of one year or less and the treatment outcomes.
Materials and Methods:
From January 2019 to May 2020, 34 patients with gradual-onset shoulder pain from recreational-level surfing activity who visited outpatient clinics were analyzed retrospectively with prospective data collection. All patients had a surf experience of one year or less as surf club members. The demographic data, including the surf-specific data and physical test, were reviewed. Simple radiographs and ultrasound of both shoulders were performed for an initial evaluation in all patients. If needed, magnetic resonance images were taken for an additional evaluation. Conservative treatments, including medication or injection, combined with trunk extension, periscapular, and core muscle training were performed in all cases. The clinical outcomes were evaluated using the visual analog scale for pain (PVAS), the Simple Shoulder Test (SST) score at the initial and final follow-up, and the patient’s level of satisfaction with treatment.
Results:
Thirty-two patients (94.1%) showed minor symptoms. The clinical findings were predominantly divided into periscapular or pectoralis muscle strain (14.7%), proximal biceps tendinopathy (38.2%), subacromial impingement (44.1%), and shoulder instability (2.9%). The common findings in ultrasound were effusion around the biceps tendon, cuff tendinosis, and subacromial bursitis. The mean PVAS and SST score improved significantly at the last follow-up (p<0.001, p<0.001). The patient’s satisfaction with treatment ranged from ‘satisfied’ to ‘very satisfied’ in 31, ‘so so’ in two, and ‘dissatisfied’ in one patient.
Conclusion
This study showed that the common pathologic conditions of shoulder pain in recreational-level beginners with a surf experience of one year or less are tendinopathy around the long head of the biceps tendon and rotator cuff. Ultrasound was helpful in rapidly diagnosing and determining the treatment plans during the primary diagnostic approach at the outpatient visit. Most cases were associated with minor symptoms that did not interfere with work or surfing and showed relatively satisfactory results for conservative treatments combined with functional muscle training.

STUDY DESIGN: Retrospective study of clinical experiences. OBJECTIVES: The correct discrimination of a compressed root is very important for proper decompression. With a foraminal disc herniation, the cephalad root is compressed. The diagnostic importance of the clinical and radiological findings was investigated. SUMMARY OF LITERATURE REVIEW: A compressed root, due to a herniated disc, is known as a caudal root (i. e. L5 root compressed by L4-5 disc herniation). In some cases, a prolapsed disc may compress the cephalad root, resulting in a difficult diagnosis. MATERIAL AND METHOD: The medical records, plain X-ray and MRI of 17 patients were reviewed, and the physical examination and MRI findings were carefully evaluated to retrospectively document the efficacy of the diagnoses. Every MRI image of each patient was graded according to the 4 point ranking system of diagnostic efficacy devised by the authors. The clinical outcomes and postoperative complications were also investigated. RESULTS: Ten, 5 and 2 of the 17 patients had L4-5, L5-S1 and L3-4 foraminal disc herniations, respectively. Eight of 10 L4-5 cases showed a positive femoral nerve stretching test. The knee jerk reflex was diminished in 7 patients, with bilateral hyporeflexia in the other 3. The body-cut axial MRI image was the most effective, and the coronal images were also very helpful, whereas the routine axial images were of least value. Most cases achieved a satisfactory clinical result. CONCLUSIONS: Foraminal disc herniations seem to be reasonably common. For the accurate discrimination of a compressed root, a thorough physical examination seems to be very important. When MRI is performed for these cases, in addition to routine studies, the body-cut axial and coronal MRI images are effective and useful, and their use is strongly recommended.

PURPOSE: We performed this study to investigate the outcome of surfactant replacement therapy (SRT) in above nearterm neonates who were required mechanical ventilatory care due to meconium aspiration pneumonia (MAP), respiratory distress syndrome (RDS) or other severe pneumonia (PN). METHODS: 48 patients, gestational period 36 weeks, who were admitted in NICU of Dongsan Medical Center, Keimyung University between July 1999 and June 2004 were enrolled. They were divided into three groups, MAP group (15 cases), RDS group (27 cases) and PN group (6 cases). All patients were received SRT and evaluated several clinical data (gestational age, oxygen index, duration of ventilator care) and outcome (complications and mortality rate) between pre-SRT and post-SRT. The mean dose of surfactant (modified bovine surfactant, Newfacten, Yuhan Co., Seoul, Korea) was 120 mg/kg. RESULTS: Among each groups, mean pre-SRT OI was higher in MAP group (213.2) than other groups, mean duration (days) of ventilatory care and oxygen therapy were similar distributions. Compared with pre-SRT values, significant improvements (P<0.05) in mean values for FiO2 and oxygenation index were documented at 12 hours after SRT. Early complications (persistent pulmonary hypertension of newborm, pneumothorax) and survival rate were lower in MAP group. Within RDS group, earlier SRT (given before 12 hours of life) revealed significantly lower early complication rate than later SRT (given after 12 hours of life) (13.3% vs 58.3%, P<0.05) CONCLUSION: Our study suggested that SRT seems to be an effective therapy in above nearterm neonates with severe pulmonary disease, and earlier SRT tends to reduce complications in RDS group than later therapy.
