Purpose: This study sought to study the effects of cross-legged sitting posture on joint motion. It also examined the correlation between the changes in the joint range of motion, musculoskeletal symptoms, and facial asymmetry. Methods: The Acumar Digital Inclinometer (Lafayette Instrument Company, USA) was used to measure the range of motion (ROM). We measured the flexion and extension of the cervical, thoracic, and lumbar spine using a dual inclinometer, and measured the ROM of the shoulder and hip joint with a single inclinometer. The Likert scale questionnaire was used to investigate musculoskeletal symptoms and facial asymmetry. Results: The data analysis was performed using the Jamovi version 1.6.23 statistical software. After confirming the normality of the ROM with descriptive statistics, it was compared with the normal ROM through a one-sample t-test. Correlation matrix analysis was performed to confirm the association between facial asymmetry and musculoskeletal symptoms. The result of the one-sample t-test showed a significant increase in the thoracic spine extension and right and left hip external rotation (p<0.001***), while most other joints were restricted. As per the frequency analysis, facial asymmetry was found to be 81.70%. Conclusion: The independent variable, namely cross-legged sitting posture led to an increase in ROM. The study also suggests that facial asymmetry and musculoskeletal symptoms could occur. Therefore, to prevent the increase and limitation of ROM and to prevent the occurrence of facial asymmetry and musculoskeletal symptoms, it is suggested that the usual cross-legged sitting posture should be avoided.

Purpose: The purpose of this study was to evaluate the clinical result of arthroscopic treatments by using suture anchors or suture anchors combined with cannulated screw in the greater tuberosity fracture of the proximal humerus fracture. Materials and Methods: From March 2004 to March 2006 we have used suture anchor or suture anchors combined with cannulated screw for 6 cases of the greater tuberosity fracture which include displaced fractures, comminuted fractures and minimally displaced fractures with comcomittent lesions such as rotator cuff tears, stiffness and labral lesion. In this retrospective study, we analyzed the clinical outcomes by using the range of motion, University of California at Los Angeles shoulder rating scale (UCLA) and the ASES shoulder index score (ASES) in the average 6 months follow up. Results: At the last follow up, average range of motion was improved to 154.3 degree, 145.8 degree, 32.6 degree and L1 vertebrae in each forward flexion, abduction, external rotation and internal rotation. Clinically the UCLA rating scales improved to 31.5 and the ASES shoulder index score (ASES) improved to 93.6 in the last follow up. Conclusion: Arthroscopic treatments by using suture anchor or suture anchors combined with cannulated screw in the greater tuberosity fracture of the proximal humerus fracture is an alternative treatment of the greater tuberosity fracture of the proximal humerus fracture.
Purpose: Scapular body fractures have generally been treated with non-surgical methods. This study reports the clinical and radiological outcomes after lateral-posterior internal fixation for treating displaced scapular body fractures. Materials and Methods: From March 2007 to May 2017, out of 40 patients who underwent internal fixation for scapular fractures, 13 cases of lateral plate fixation of a scapular body fracture were reviewed retrospectively. Preoperative and postoperative displacement, angulation and glenopolar angle (GPA) were measured. The range of shoulder motion, visual analogue scale (VAS), and disabilities of the arm, shoulder, and hand (DASH), and Constant score were assessed at the last follow-up. Results: The mean follow-up period was 17.7 months (range, 6-45 months). The mean preoperative GPA was 23.3°±3.96° (range, 17.8°-28.1°) and the postoperative GPA was 31.1°±4.75° (range, 22.5°-40.1°). Injury to the suprascapular nerve, nonunion, fracture redisplacement, metallic failure, or infection did not occur. At the last follow-up, the mean range of motion was 150.5°±19.3° in forward flexion, 146.6°±2.34° in lateral abduction, 66.6°±19.1° in external rotation, and 61.6°±18.9° in internal rotation. The VAS, DASH, and Constant scores were 1.7±1.3, 6.2±2.4, and 86±7.9 points, respectively. Conclusion: A scapular body fracture with severe displacement, angulation and marked decreased GPA can be stabilized by lateralposterior plate fixation using the appropriate surgical technique with good functional and radiological results.

According to our recent investigation that the increase in the occlusal vertical dimension made the appendage muscle strength got higher, the occlusal appliances were made by increasing the occlusal vertical dimension "from the centric relation" position of the mandible. In this experiment, the authors tried to study the change in the appendage muscle strength due to increase in occlusal vertical dimension from intercuspal position(ICP) of mandible with the same subjects and manner as the former experiment. For this study, ten male athletes in a mean age of 23 year who were joined the former study were selected. All the subjects had a complete or almost complete set of natural teeth and reported no subjective symptoms of temporomandibular disorders. Upper and lower casts were mounted on the semi-adjustable articulator at the intercuspal position and a point was marked on the attached gingival area between the right canine and the right 1st. premolar in each upper and lower cast. From the points, the occlusal vertical dimension was increased by 2mm, 3.5mm and 5mm, and then each 10 maxillary type occlusal splint at each 3-increased position were fabricated with heat curing clear acrylic resin. Including the intercuspal position, the 3 kinds of occlusal splints were placed on the subjects individually, and then isokinetic muscle strength on 7 parts of the human appendage which are shoulder, knee, ankle, wrist, forearm, elbow and hip was measured with the CYBEX 6000 SYSTEM (Lumex, NewYork, USA). The results were as follows: The highest mean value in muscular strength was shown at the position of 2mm-increased vertical dimension. The muscle strength during internal/external rotation of shoulder and knee, plantarflexion of ankle, flexion of elbow, and flexion and extension of hip at the increased occlusal vertical dimension position were significantly higher than them at the intercuspal position (p<0.05). Only in view of the increase in the appendage muscle strength, regardless of the way of making the occlusal splints by elevating the occlusal vertical dimension from the centric relation position or intercuspal position, the occlusal splints had an effect on the increase of isokinetic muscle strength at the occlusal vertical dimension which increased within the proper range on the habitual arc of closure.
Recently among several tennis techniques forehand stroke has been greatly changed in the aspect of spin, grip and stance. The most fundamental factor among the three factors is the stance which consists of open, square and closed stance. The purpose of this study was to investigate the relations between the segments of the body, the three dimensional anatomical angle according to open stance patterns during forehand stroke in tennis. For the movement analysis three dimensional cinematographical method(APAS) was used and for the calculation of the kinematic variables a self developed program was used with the LabVlEW 6.1 graphical programming(Johnson, 1999) program. By using Eular's equations the three dimensional anatomical Cardan angles of the joint and racket head angle were defined 1. In three dimensional maximum linear velocity of racket head the X axis showed $11.41{\pm}5.27m/s$ at impact, not the Y axis(horizontal direction) and the z axis(vertical direction) maximum linear velocity of racket head did not show at impact but after impact this will resulted influence upon hitting ball It could be suggest that Y axis velocity of racket head influence on ball direction and z axis velocity influence on ball spin after impact. the stance distance between right foot and left foot was mean $74.2{\pm}11.2m$. 2. The three dimensional anatomical angular displacement of shoulder joint showed most important role in forehand stroke. and is followed by wrist joints, in addition the movement of elbow joints showed least to the stroke. The three dimensional anatomical angular displacement of racket increased flexion/abduction angle until the impact. after impact, The angular displacement of racket changed motion direction as extension/adduction. 3. The three dimensional anatomical angular displacement of trunk in flexion-extension showed extension all around the forehand stroke. The angular displacement of trunk in adduction-abduction showed abduction at the backswing top and adduction around impact. while there is no significant internal-external rotation 4. The three dimensional anatomical angular displacement of hip joint and knee joint increased extension angle after minimum of knee joint angle in the forehand stroke, The three dimensional anatomical angular displacement of ankle joint showed plantar flexion, internal rotation and eversion in forehand stroke. it could be suggest that the plantar pressure of open stance during forehand stroke would be distributed more largely to the fore foot. and lateral side.

Purpose: We wanted to analyze and report on the radiologic and clinical results of prospective Hook plate fixation for unstable distal clavicle fractures after a minimum of 2 years follow up. Materials and Methods: We followed up 17 out of 20 cases that underwent prospective Hook plate fixation from 2008 to 2009. We performed radiologic follow up at 2 weeks, 6 weeks, 3 months, 6 months, 18 months and 24 months postoperatively. The clinical results were evaluated at 12 months and 24 months postoperatively. Results: The mean period for bony fusion was 14.5 weeks and the plate was removed after an average of 20.2 weeks. The VAS pain scores were 0.7 and 0.8, the UCLA scores were 33.5 and 33.3, the ASES scores were 92.8 and 92.5, the Constant-Murley scores were 81.5 and 77.0, the KSS scores were 92.5 and 94.3 and the ranges of motion were $173.3^{\circ}$ and $173.7^{\circ}$ of flexion, $56.0^{\circ}$ and $54.5^{\circ}$ of external rotation, $62.3^{\circ}$ and $63.5^{\circ}$ of the internal rotation, $172.0^{\circ}$ and $172.6^{\circ}$ of abduction and $43.3^{\circ}$, and $42.9^{\circ}$ of extension at 1 and 2 years follow-up, respectively. There was no statistically significant difference of clinical outcomes and the range of motion at 1 year and 2 year postoperatively (p>0.05). There was no other complication except 1 case of delayed union. Conclusion: For Hook plate fixation at 2 years postoperatively, the complications will be decreased and excellent clinical results should occur.
Objective: To evaluate if acromial locking in hook plate is necessary for surgical treatment of acromioclavicular dislocation by compare Wolter plate and AO hook plate. Methods: Seventy one patients who have Rockwood type III to V acromioclavicular joint dislocation treated with AO hook plate and Wolter plate were involved. Among them, 39 patients were treated with Wolter hook plate and 32 patients with AO hook plate. The Constant-Murley score and the range of motion of shoulder joint were measured on postoperative 1st ,$3^{rd}$, $6^{th}$ and $12^{th}$ months, and the radiological complications involving plate and bone were investigated. Results: Constant-Murley score of postoperative one year were $83.2{\pm}6.8$ in AO hook plate group and $85.2{\pm}5.3$ in Wolter plate group without statistical difference (p<0.05). Faster recover of forward elevation and external rotation were examined in Wolter plate group at first and third months after surgery than those of AO hook plate group, but there were no significant difference between after six months or later after surgery. Four cases of loosen or broken screws and one case of pull-out of plate were found in Wolter plate group. Seven cases of subacromial bony erosion and one periprosthetic fracture were found in AO hook plate group. Conclusion: Although clinical outcomes of both two methods were same, no matter if acromial locking system was or not. More radiological complication of plate and bone were found in AO hook plate than that of Wolter plate. However also had disadvantage like larger incision during surgery.
Purpose: The purpose of this study is to provide the clinical outcomes of arthroscopic type II SLAP repair in non-athletes, and to compare the clinical outcomes between those who had isolated type II SLAP lesion and those who had combined partial thickness supraspinatus tear that did not required a combined repair. Materials and Methods: From July 2005 to January 2007, 142 consecutive type II SLAP lesions were treated with arthroscopic surgery. The inclusion criteria for the study were; (1) younger than 50 years old; and (2) non-athletes. Exclusion criteria were; (1) prior surgery, fracture or combined recurrent dislocation history on the affected shoulder; (2) combined full thickness rotator cuff tear or PTST (>50% thickness) patient that needed repair; and (3) combined infection, arthritis or inflammatory disease. Remaining 19 patients meet the criteria. Among them, 13 had combined PTRCT that did not require repair (Group I), and 6 had isolated type II SLAP lesion without combined supraspinatus tear (Group II). The mean age was 36.7 years (29~49 years), mean symptom duration was 39.1 months (3~216 months) and mean follow-up was 19.0 months (12~27 months). In all patients, the range of motion of affected shoulder, pain and function visual analogue scale (PVAS, FVAS), the Constant score and UCLA score were evaluated preoperatively and postoperatively. Results: In group I, external rotation at side was decreased significantly (p=0.003),but there were no statistical significant change at the remains(p>0.05). And there were no differences between groups (p>0.05). At the final follow-up, all clinical outcome measurements improved after surgery with statistical significance (p<0.05): UCLA score, $22.8{\pm}5.2$ to $32.8{\pm}2.1$; Constant score, $79.4{\pm}8.6$ to $94.9{\pm}4.3$; PVAS $5.4{\pm}2.7$ to $1.1{\pm}1.4$; FVAS $63.2{\pm}15.3$ to $93.4{\pm}7.3$. But, in group comparison of the mean UCLA score and Constant score, there were no statistical significant differences between two groups. Conclusion: Arthroscopic repair of type II SLAP lesion provided good clinical outcomes in nonathletic population. Combined partial thickness supraspinatus tear does not seem to hamper the final outcome at minimal 1 year follow-up.
Purpose: There are various known methods for arthroscopic rotator cuff repair. The purpose of this retrospective study is to report on the clinical results and anatomical results of UU repair surgery, which is a new repair method. Materials and Methods: We enrolled 156 patients (88 men and 68 women) who underwent UU repair for rotator cuff tears from January 2009 to May 2010 in our hospital. Their average age was 55 years old (range: 38~75 years old) and the average follow-up period was 12 months (range: 6~23 months). For determining the results, we evaluated the VAS for pain, the daily living index (ADL) in the ASES scores, the UCLA and KSS scores, and all these tests were conducted at the first hospital visit and 6 months and 1 year after surgery and at the final follow-up. During the follow-up period, MRI was performed 3 and 6 months after surgery only in the patients who consented to MRI scans to confirm the presence of re-rupture. Results: The average scores of the VAS as a pain indicator decreased from 7.0 before surgery to 2.7 after surgery (p<0.05). The UCLA and KSS scores increased from 22.2 to 32.5 and from 83.7 to 91.5, and the changes was significant (p<0.05). For the active joint range of motion, the average forward flexion was improved from 125 to 175 degrees, the average lateral external rotation was improved from 38 to 58 degrees, and the average abduction was improved from 104 to 169 degrees. Out of a total of 156 patients, re-rupture was observed in 4 cases (3%) of 117 cases (75%) for which MRI was performed (with consent) between 3 and 6 months after surgery. Conclusion: UU repair surgery as arthroscopic repair of rotator cuff tear is a good repair method that shows excellent clinical results and a low re-rupture rate.

Purpose: We describe a all-arthroscopic technique for decompression of spinoglenoid ganglion cyst and present our clinical results for this procedure. Materials and Methods: From March 2006 to June 2009, eight patients (7 males, 1 female; mean age 40.6 years; range: 21~61) were included who underwent arthroscopic decompression of spinoglenoid ganglion cyst. The most common symptoms were vague shoulder pain and external rotation weakness, which lasted 6.4 months (range: 3~8) on average. Five of eight patients were noted abnormalities on electromyographic (EMG) examination to have suprascapular nerve neuropathy and magnetic resonance imaging (MRI) showed spinoglenoid ganglion cysts in all eight patients and the cyst size was 2.6 cm (range: 1.8~3.6). Labral pathology was identified intraoperatively in all patients and the cysts were decompressed by the posterosuperior capsulotomy under arthroscopic control and labral repair with suture anchors was performed in six patients. Results: The average clinical outcome scores including Constant and Murley, Simple shoulder test (SST) all improved significantly at the time of the final follow-up and there were no complications resulting from the procedures. All patients including the patients with abnormal EMG study recovered strength on isokinetic strength testing. Follow-up MRI scans were performed on all patients at a mean of 5.2 months postoperatively (range: 3~12) revealed complete resolution of the cysts and no evidence of recurrences were seen at an average of 18 months (range: 12~26) of follow-up. Conclusion: Arthroscopic decompression of spinoglenoid ganglion cyst effectively restores patient function and all patients in this study showed improvement in their postoperative MRI findings. Arthroscopic decompression is also useful in the appropriate treatment for labral pathology and may contribute to decreased risk of cyst recurrence.
