Meniscal tears are a common source of knee pain in military personnel. We aimed to investigate the arthroscopic findings of isolated meniscal tears in soldiers younger than 30 years of age. Between May 2011 and April 2014, a total of 36 soldiers with 37 knees who underwent arthroscopic surgeries for isolated meniscal tears were included in this study. All patients were male soldiers and average age was 22 years (range, 19 to 30 years). Thirty patients (83%) were identified as having trauma in sports activity or military training, but no definite trauma was documented in six patients. We analyzed whether medial or lateral meniscus, the location and type of tear according to the arthroscopic findings. The incidence of meniscal tears was nearly same for both knees (right 18 and left 19). Twenty-six of 37 tears (70%) were found in the lateral meniscus and 11 (30%) in the medial meniscus. Twenty-five tears (68%) were located in mid body and traumatic vertical type tears (65%) were more common than degenerative horizontal type tears (35%). Although our study based on relatively small cohort, isolated meniscal tears in young soldiers were usually resulted from trauma such as sports or ranger training and commonly located in lateral meniscus. Regarding the type of tear, traumatic vertical type was more common than degenerative horizontal type.

Humeral head chondrolysis has been widely reported as a devastating complication after arthroscopic shoulder surgery; however little is known about post-arthroscopic humeral head osteonecrosis. We experienced a 66-year-old female patient with rapidly progressive osteonecrosis of the humeral head only seven months after arthroscopic Bankart and rotator cuff repair. The patient had no systemic risk factors for osteonecrosis. A satisfactory result was achieved with reverse total shoulder arthroplasty for severe humeral head destruction and an irreparable massive rotator cuff tear. Shoulder surgeons should be aware of such severe complication, perform routine radiographs, and pay close attention to the presence of constant pain or loss of motion after arthroscopic shoulder surgery.

Scapulothoracic bursitis refers to inflammation of the bursae secondary to trauma or overuse owing to sports activities or work. It usually causes persistent pain and scapulothoracic crepitus by irritation of bursa but can be presented as painless mass around chest wall. We report a case of scapulothoracic bursitis in a baseball pitcher presenting as rapidly growing chest wall mass confused with a soft tissue tumor. Computed tomography and magnetic resonance imaging revealed as a well-demarcated cystic mass situated between the scapula and chest wall. Incisional drainage resulted in complete resolution of the mass within a couple of weeks. Scapulothoracic bursitis may be presented as painless huge mass in overhead sports athlete and one of the differential diagnoses of soft tissue tumor of the chest wall.

The purpose of this study is to evaluate the gravity valgus stress ultrasonographic findings of ulnar collateral ligament (UCL) injury among baseball players. Twenty-eight (age, 16-30; mean, 19.5 years) UCL injured players, diagnosed by magnetic resonance imaging (MRI), were examined by bilateral elbow ultrasonography. On MRI findings, partial and complete tears were 17 and 11 players, respectively. Ultrasonographic examinations were performed in 90 degree elbow flexion with gravity valgus stress, and abnormalities around UCL and ulnohumeral distance were compared with contralateral uninjured elbow. 22 of 28 (79%) players had sonographic abnormalities in injured elbow such as thickening, wavy contour of the UCL (32%), hypoechoic foci in the ligament (43%), osteophyte on trochlear or ulnar articular margin (36%), joint effusion (29%) and ossicles in or around the UCL (68%) that were the most common finding in both partial and complete tears. In all players, the ulnohumeral distance was significantly wider on the injured side than it was on the uninjured side (4.0+/-1.5 mm and 2.5+/-0.43 mm, respectively; p=0.015). Significant increased average ulnohumeral distance in injured elbow was observed with complete UCL tears compared with partial tears (5.4+/-0.9 mm and 3.1+/-0.8 mm, respectively; p=0.021) and the mean difference between injured and uninjured elbow was more significant in complete tears than partial tears (2.8+/-1.2 mm and 0.7+/-0.6 mm, respectively; p=0.012). Gravity valgus stress ultrasonography is rapid noninvasive diagnostic tool and can provide clinicians valuable information regarding the condition of the UCL and medial elbow laxity in partial and complete UCL tear players.

This study is to evaluate the abnormalities in the kinetic chain in the players with little league elbow during the medical screening of middle school baseball teams. Ninety-three players were examined with elbow ultrasonography in the field. Using kinetic chain evaluation test, 27 players sonogrphically diagnosed of little league elbow in dominant arm were compared with 25 players who were normal as control. Scapular-spine distance, horizontal flexion test, combined abduction test, and glenohumeral internal rotation deficit were used for evaluating kinetic chain in the upper extremities, while tightness of quadriceps and hamstring muscles, internal rotation of stance leg, and external rotation of stride leg were used for lower extremities. Also, the single leg stance test and finger-floor distance were used for core stability and flexibility. Twenty-five of 27 players (93%) having little league elbow showed kinetic chain abnormalities of either upper or lower extremities or trunk. This rate was significantly higher for the players having the little leaguer's elbow than control (28%) (p=0.017). Each specific tests for evaluating kinetic chain were also more prevalent in little league elbow group than control, and the abnormalities in the upper extremity were more common than those in lower extremity (p=0.026). Combined abduction test (23/27) and limitation of internal rotation of stance leg (16/27) were the most prevalent abnormalities in upper and lower extremity test, respectively. Our findings showed that there are many abnormalities in kinetic chain in players having the little league elbow and it may be associated with pathogenesis of little league elbow.

Inversion injury of the lateral ankle ligaments is very common. Few studies, however, have focused on avulsion fracture of the lateral ankle ligaments. A fracture producing a small fragment usually avulsed from lateral malleolus and may be easily misdiagnosed as a sprain because the fragment is superimposed on the lateral malleolus and goes undetected on early radiographs, especially in skeletally immature patients. We present a case of isolated avulsion fracture of the talar attachment of the anterior talofibular ligament in 13-year-old male patient. Diagnosis was confirmed by computed tomography and avulsed fragment was fixed to original talar footprint with suture anchors. A high level of suspicion must be maintained to obtain an accurate diagnosis of avulsion fracture in inversion ankle injury because of the high incidence in children and to prevent recurrent instability.

BACKGROUND/AIMS: Gastro-esophageal reflux disease (GERD) is a chronic condition, with 50-80% of patients experiencing recurrence within one year following completion of initial treatment. The present study aimed to estimate recurrence rate and treatment response in GERD patients treated with proton pump inhibitor. METHODS: A total of 207 symptomatic GERD patients, which were confirmed by endoscopy from July 2008 till January 2009, were enrolled. They were divided into non-erosive reflux disease (NERD) group and erosive reflux disease (ERD) group by endoscopic findings. Patients were treated with lansoprazole 15 mg (NERD group) or 30 mg (ERD group) once daily for 8 weeks. The presence of symptoms was assessed in each patient at baseline and post-treatment using a questionnaire. Subsequent symptomatic recurrence on the cessation of therapy in each improved patients was checked by telephone survey or outpatient interview. RESULTS: Ninety-four patients and 113 patients were first diagnosed with NERD and ERD, respectively. The mean post-treatment follow-up period was 24.4+/-8.5 weeks. Recurrence rate was 40.0% (NERD, 43.8%; ERD, 37.1% (p=0.224)). Recurrence time was 10.1+/-5.8 weeks (NERD 9.6 weeks; ERD, 10.6 weeks (p=0.444)). Regarding the symptom improvement after 8 week therapy with lansoprazole, 89.4% (NERD, 85.1%; ERD, 92.9% (p=0.056)) of total patients were symptomatically improved. CONCLUSIONS: Forty percentage of GERD patients recurred within 6 months following the completion of 8 week therapy with lansoprazole. Recurrence rate, recurrence time, and rate of symptom improvement were not significantly different between NERD group treated with half dose and ERD group treated with full dose lansoprazole.

BACKGROUND/AIMS: Eosinophilic esophagitis (EE) is a chronic inflammatory disorder characterized by abnormal dense eosinophilic infiltration of esophageal mucosa and results in dysphasia and food impaction. EE is being increasingly recognized in adults. The prevalence is largely unknown. This study was performed to evaluate the detection rate of EE diagnosed based on pathologic criteria and to define the clinical characteristics of EE in Korea. METHODS: We reviewed biopsy specimen of the 1,609 patients who underwent esophageal biopsy from January 2006 till August 2008. The presence of more than 20 eosinophils per high power field in biopsy specimens was considered cases of EE. Clinical information and endoscopic findings were obtained. RESULTS: 7 (0.4%) patients were diagnosed as EE based on pathologic criteria retrospectively. Clinical symptoms were epigastric pain (43%), regurgitation (29%), dyspepsia (14%), and no symptom (14%). Endoscopic findings were whitish exudates or granules (57%), esophageal polyp (29%), and hyperemic change (14%). Two patients received treatment. One patient with bronchial asthma improved after treatment with inhaled corticosteroid, and one patient improved after 8 week proton pump inhibitor therapy. CONCLUSIONS: Eosinophilic esophagitis was found in 0.4% of the total esophageal biopsied cases. Our results suggest that Korean patients with eosinophilic esophagitis showed symptoms mimicking gastroesophageal reflux disease and atypical endoscopic findings. Therefore, regardless of the gross appearance of the mucosa, meticulous diagnostic approaches are needed for patients with swallowing difficulty and lack of response to proton pump inhibitor.

BACKGROUND: To evaluate the clinical results and operation technique of arthroscopic repair of combined Bankart and superior labrum anterior to posterior (SLAP) lesions, all of which had an anterior-inferior Bankart lesion that continued superiorly to include separation of the biceps anchor in the patients presenting recurrent shoulder dislocations. METHODS: From May 2003 to January 2006, we reviewed 15 cases with combined Bankart and SLAP lesions among 62 patients with recurrent shoulder dislocations who underwent arthroscopic repair. The average age at surgery was 24.2 years (range, 16 to 38 years), with an average follow-up period of 15 months (range, 13 to 28 months). During the operation, we repaired the unstable SLAP lesion first with absorbable suture anchors and then also repaired Bankart lesion from the inferior to superior fashion. We analyzed the preoperative and postoperative results by visual analogue scale (VAS) for pain, the range of motion, American Shoulder and Elbow Surgeon (ASES) and Rowe shoulder scoring systems. We compared the results with the isolated Bankart lesion. RESULTS: VAS for pain was decreased from preoperative 4.9 to postoperative 1.9. Mean ASES and Rowe shoulder scores were improved from preoperative 56.4 and 33.7 to postoperative 91.8 and 94.1, respectively. There were no specific complication and no significant limitation of motion more than 10 degree at final follow-up. We found the range of motions after the arthroscopic repair in combined lesions were gained more slowly than in patients with isolated Bankart lesions. CONCLUSIONS: In recurrent dislocation of the shoulder with combined Bankart and SLAP lesion, arthroscopic repair using absorbable suture anchors produced favorable clinical results. Although it has technical difficulty, the concomitant unstable SLAP lesion should be repaired in a manner that stabilizes the glenohumeral joint, as the Bankart lesion can be repaired if the unstable SLAP lesion is repaired first.
