PURPOSE: In patients with independent mobility, full hip range of motion and sufficient muscle strength for daily life without cognitive impairment, treatment of a femoral neck fracture with total hip arthroplasty (THA) may be a better option compared to bipolar hip hemiarthroplasty. Here, functional outcomes and complications in patients who underwent THA for femoral neck fracture based on their comorbidity status were analyzed. MATERIALS AND METHODS: Between January 2013 and December 2018, 110 patients were treated with THA for femoral neck fractures at our institution. These patients were retrospectively analyzed for clinical outcomes at final follow-up (mean=24.4 months, range: 6–81 months) using the Harris hip score (HHS) and the presence or absence of two potential comorbidities: i) diabetes mellitus (DM; 35 with and 75 without) and ii) hypertension (HTN; 50 with and 60 without). RESULTS: The incidence of superficial infections at the surgical site in patients with DM was significantly higher compared with patients without DM (P=0.024). There were no significant differences in other potential complications based on DM status. HHS at final follow-up between patients with and without DM and with and without HTN were not significantly different (83.3 vs. 81.0, P=0.39 and 81.6 vs. 82.4, P=0.75, respectively). CONCLUSION: Superficial infections occurred more frequently in patients with DM compared with patients without DM. DM and HTN status are not correlated with HHS.

BACKGROUND: Since the establishment of biological augmentation to improve the treatment of rotator cuff tears, it is imperative to explore newer techniques to reduce the retear rate and improve long-term shoulder function after rotator cuff repair. This study was undertaken to determine the consequences of a gel-type atelocollagen injection during arthroscopic rotator cuff repair on clinical outcomes, and evaluate its effect on structural integrity. METHODS: Between January 2014 and June 2015, 121 patients with full thickness rotator cuff tears underwent arthroscopic rotator cuff repair. Of these, 61 patients were subjected to arthroscopic rotator cuff repair in combination with an atelocollagen injection (group I), and 60 patients underwent arthroscopic rotator cuff repair alone (group II). The visual analogue scale (VAS) for pain and the Korean Shoulder Society (KSS) scores were evaluated preoperatively and postoperatively. Magnetic resonance imaging (MRI) was performed at 6 months postoperatively, to assess the integrity of the repair. RESULTS: VAS scores were significantly lower in group I than in group II at 3, 7, and 14 days after surgery. KSS scores showed no significant difference between groups in the 24 months period of follow-up. No significant difference was obtained in the healing rate of the rotator cuff tear at 6 months postoperatively (p=0.529). CONCLUSIONS Although a gel-type atelocollagen injection results in reduced pain in patients at 2 weeks after surgery, our study does not substantiate the administration of atelocollagen during rotator cuff repair to improve the clinical outcomes and healing of the rotator cuff.

BACKGROUND: This study investigated and evaluated the clinical outcomes of intra-articular lesions of traumatic anterior shoulder dislocation (TASD) associated with greater tuberosity (GT) fracture of the humerus. METHODS: Subjects included 20 patients who were surgically or non-surgically treated for GT fracture of the humeurs with TASD, and followed-up for at least 2 years. The mean follow-up period was 54.1 months (range, 24–105 months). Of the 20 patients, 12 were treated surgically. Intra-articular lesions were identified randomly on magnetic resonance imaging scans (repeated thrice) by experienced radiologists and orthopedic surgeons. The accompanying intra-articular lesions were left untreated. Clinical outcomes were evaluated by Simple Shoulder Test (SST) and Western Ontario Shoulder Instability index (WOSI) at the last follow-up. RESULTS: Intra-articular lesions were identified in 19 patients: 7 Bankart lesions, 15 humeral avulsion of the glenohumeral ligament lesions, 3 glenoid avulsion of the glenohumeral ligament lesion, and 6 inferior capsular tears. Two or more intra-articular lesions were identified in 6 patients. The mean SST score was 10.9 and the mean WOSI score was 449.3 at the last follow-up. CONCLUSIONS: For GT fracture of the humerus with TASD, a high frequency of diverse intra-articular lesions was identified. There were no incidence of recurrent shoulder dislocations, and good clinical outcomes were obtained without treatment of the intra-articular lesions. We thereby comprehend that although intra-articular lesions may occur in TASD associated with GT fracture of the humeurs, merely treating the GT fracture of the humerus is sufficient.

PURPOSE: We performed clinical and radiological evaluation of surgical outcomes of congenital vertical talus. MATERIALS AND METHODS: Fifteen surgically treated feet in 9 patients (6 bilateral and 3 unilateral) which were followed-up for at least 2 years were included. Mean patient age at the time of surgery was 10.9 months. The surgical technique was a one-stage correction using the Kumar technique with a Cincinnati skin incision. In 7 feet we also transferred half of the tibialis anterior to the talar neck (the Grice technique). Radiologic parameters (talo-calcaneal angle, talo-first metatarsal angle, tibio-talar angle, tibio-calcaneal angle) were analyzed pre- and postoperatively and at the last follow-up, and clinical outcomes by the Laaveg-Ponseti score. RESULTS: Talus orientation was improved in all patients. All radiologic parameters showed statistically significant improvement by the last follow-up. The mean Laaveg-Ponseti score at the last follow-up was 16 for patient satisfaction, 16 for function, and 24 for pain. There was no recurrence, however one case of talar neck fracture occurred during the tibialis anterior transfer. CONCLUSION: One-stage surgical correction for congenital vertical talus at an early age provides satisfactory functional and cosmetic results.

PURPOSE: We evaluated outcomes of treatment in medial condyle fracture of the distal humerus in children. MATERIALS AND METHODS: Seven patients (4 females, 3 males) who were treated at the Pusan National University Hospital and followed-up until skeletal maturity after treatment were included. The average age at the time of fracture was 4.6 years (range, 2 to 10 years). Treatment was performed from 1 day to 6 months after the fracture: 4 patients underwent a surgical treatment for 17 days, 2 months, 2 months and 6 months after fracture, respectively. All fractures were Milch type 1. Five patients had Kilfoyle type 3, and two patients had type 2 fractures. Final outcomes were evaluated by the Mayo elbow performance score and carrying angle. RESULTS: There were 3 excellent, 3 good and 1 fair result at the final follow-up. There was no elbow pain in any of the patients. One of the four patients who underwent a late surgical treatment received corrective osteotomy due to cubitus varus. All four patients had a limitation of elbow motion. The other three patients who had accurate diagnosis and treatment had a full range of motion. CONCLUSION: Diagnosis of medial condyle fracture of the distal humerus based on plain radiograph is difficult in children due to its cartilaginous structures. When a patient shows pain, tenderness and swelling on the medial side of the elbow, an additional examination with magnetic resonance imaging may be required even if no fracture line is found in the radiograph. Accurate diagnosis and early treatment is important for good results.

BACKGROUND/AIMS: Vaccination against hepatitis A virus (HAV) is recommended for patients with chronic hepatitis B (CHB), since they are potentially at an increased risk of HAV-related morbidity and mortality. However, little is known about the adherence to these recommendations in the community. This study evaluated the current vaccination status and immunity against HAV among Korean military soldiers with CHB. METHODS: We performed a prospective study of Korean military soldiers from August 2008 to January 2009. We enrolled 96 soldiers with CHB on a consecutive basis. We assessed their vaccination history and the presence of anti-HAV immunoglobulin G (IgG). RESULTS: The HAV vaccination rate of the soldiers enrolled in our study was 2% (2 of the 96 soldiers). The seroprevalence rates of anti-HAV IgG among military soldiers without a vaccination history were 0%, 50%, and 100% for those aged 19-29 years (n=71), 30-39 years (n=8), and 40 years or older (n=15), respectively (p<0.001). CONCLUSIONS: The HAV vaccination rate is very low among military soldiers. Public health efforts aimed at raising awareness about HAV vaccination in patients with CHB should be strongly encouraged.
