We aimed to assess the effect of plate hook bending in treatment of acromioclavicular (AC) dislocation by analyzing clinical and radiological results according to the angle of the plate hook (APH). Methods: This was a retrospective, observational, case-control study including 76 patients with acute AC joint dislocation that were divided into two groups according to treatment with bent or unbent plate hook. The visual analog scale (VAS), the American Shoulder and Elbow Surgeons (ASES) shoulder score, and range of motion (ROM) were evaluated as clinical outcomes. Comparative coracoclavicular distance (CCD) was measured to evaluate radiological outcomes. Results: While the VAS and ASES of the bending group at 4 months after surgery were significantly higher (p=0.021 and p=0.019), the VAS and ASES of the bending group at other periods and ROM of the bending group showed no significant difference. The initial CCD decreased from 183.2%±25.4% to 114.3%±18.9% at the final follow-up in the bending group and decreased from 188.2%±34.4% to 119.1%±16.7% in the non-bending group, with no statistical difference (p=0.613). The changes between the initial and post-metal removal CCD were 60.2%±11.2% and 57.3%±10.4%, respectively, with no statistical difference (p=0.241). The non-bending group showed greater subacromial osteolysis (odds ratio, 3.87). Pearson’s coefficients for the correlation between APH and VAS at 4 months after surgery and for that between APH and ASES at 4 months after surgery were 0.74 and –0.63 (p=0.027 and p=0.032), respectively. Conclusions: The APH was associated with improved postoperative pain and clinical outcomes before implant removal and with reduced complications; therefore, plate hook bending is more useful clinically during plate implantation.

Sarcopenia-related falls and fractures are increasing worldwide due to the aging population. The purpose of this study was to 1) evaluate anthropometric characteristics related to hip fracture in Korean patients, 2) investigate sarcopenia prevalence in hip fracture (HF) and non-hip fracture (NF) groups, and 3) investigate the correlation between sarcopenia and osteoporosis. This case-control study examined 359 HF and 1,614 NF normal populations using Korea National Health and Nutrition Examination Survey data. We performed whole-body dual energy X-ray absorptiometry to analyze body composition using the skeletal muscle mass index (SMI: lean mass/height2) and bone mineral density (BMD). In the HF group, using the AWGS definition, the prevalence of sarcopenia in women and men was 44.3% and 68.2%, respectively; in the NF group, it was 7.1% and 16.1%, respectively. Lower appendicular SMI (P < 0.001), leg muscle mass (P < 0.001), and higher prevalence of sarcopenia (P < 0.001) were observed in the HF group after adjustment for age and gender. In multivariate analysis, sarcopenia (OR = 6.52; 95% CI = 4.67-9.09), age (OR = 1.15; 95% CI = 1.13-1.17), and osteoporosis (OR = 1.87; 95% CI = 1.35-2.58) were associated with the occurrence of a hip fracture. This study showed a higher prevalence of sarcopenia in patients with hip fractures compared with a normal population, and higher prevalence of sarcopenia in men.

PURPOSE: To compare the clinical results of spontaneous rupture of extensor pollicis longus tendon treated by palmaris longus tendon graft (group I) versus extensor indicis proprius tendon transfer (group II). MATERIALS AND METHODS: Out of twenty-five patients who suffer from spontaneous extensor pollicis longus tendon rupture, twelve patients were treated by palmaris longus tendon graft and thirteen patients were treated by extensor indicis proprius tendon transfer. Postoperatively thumbs were immobilized with thumb spica splint for three weeks. Active and passive movement was allowed subsequently for six weeks. The functions of the thumbs were assessed by the Geldmacher criteria and statistically compared. RESULTS: The overall outcome was excellent in 5(20%) of patients and good in 17(68%) of patients and satisfactory in 3(12%) of patients. The mean scores using the Geldmacher criteria were 18.50 for palmaris longus tendon graft and 19.69 for extensor indicis proprius tendon transfer. No significant difference was noted between two groups. CONCLUSION: Both methods establish equally good clinical results in patient with chronic extensor pollicis longus tendon rupture. Extensor indicis proprius tendon transfer seems more available methods.

Patients undergone partial maxillectomy experience post-operative masticatory, phonetic, and swallowing difficulties. They also encounter social and psychological challenges due to changes in their facial appearances. Thus, functional and esthetic recovery through maxillofacial prosthesis becomes significant for these patients. The objective of an appropriate obturator is to restore palate and improve phonetic and swallowing ability by separating the oral cavity, nasal cavity, maxillary sinus, and nasopharynx. In this case report, an obturator was fabricated for a patient who had partial resection from the maxillary posterior region to the pharynx due to squamous cell carcinoma. The purpose of this case study is to describe the results because the patient was successfully improved both functionally and esthetically.

PURPOSE: Adenoid cystic carcinoma is a rare type of eccrine sweat gland carcinoma. Although it is mostly known as a neoplasm of the salivary gland, it could occur as a primary skin tumor. We present a patient with a primary cutaneous adenoid cystic carcinoma at the genital area. METHODS: A 60-year-old man had a slowly growing 1 cm sized single tender mass near the left scrotum and he underwent excisional biopsy at a local clinic. A diagnosis of adenoid cystic carcinoma was made and thus he was transferred to our hospital. In physical examination, other specific findings were not detected except a linear scar caused by a previous skin biopsy near the left scrotum. In CT scan, PET-CT scan and endoscopy, there was no evidence of neoplasm in other organs. It was diagnosed as the primary cutaneous adenoid cystic carcinoma and then wide excisions were performed including total 4.5cm margin of normal skin. RESULTS: Microscopic findings revealed proliferation of tumor cell islands with cribriform or tubular patterns containing several round, pseudocystic structures. The tumor cells showed basaloid cells with uniform and small nuclei. Tumor cells infiltrated into the dermis and upper portion of subcutaneous tissue. There was multifocal perineural invasion of tumor cells. In postoperative 6 months, we found no recurrence and other complications. CONCLUSION: Herein we found a rare case of primary cutaneous adenoid cystic carcinoma at the genital area.

PURPOSE: The purpose of this study was to analyze the effects of the splinted implant prosthesis in a reconstructed mandible using three-dimensional finite element analysis. MATERIALS AND METHODS: Three-dimensional finite element models were generated from a patient's computed tomography data. The patient had undergone partial resection of the mandible that covered the area from the left canine to the right condyle. The mandible was reconstructed using a fibula bone graft and dental implants. The left mandibular premolars and molars remained intact. Three types of models were created. The implant-supported prosthesis was splinted and segmented into two or three pieces. Each of these models was further subcategorized into two situations to compare the stress distribution around normal teeth and implants. Oblique loading of 300 N was applied on both sides of the mandible unilaterally. The maximum von Mises stress and displacement of the models were analyzed. RESULTS: The stress distribution of the natural mandible was more uniform than that of the reconstructed fibula. When the loading was applied to the implant prosthesis of reconstructed fibula, stress was concentrated at the cortical bone around the neck of the implants. The three-piece prosthesis model showed less uniform stress distribution compared to the others. Displacement of the components was positively correlated with the distance from areas of muscle attachment. The three-piece prosthesis model showed the greatest displacement. CONCLUSION: The splinted implant prosthesis showed a more favorable stress distribution and less displacement than the separated models in the reconstructed mandible.

. This study aims to compare the marginal fitness of two types of implant-supported fixed dental prosthesis, i.e., cementless fixation (CL.F) system and cement-retained type. MATERIALS AND METHODS. In each group, ten specimens were assessed. Each specimen comprised implant lab analog, titanium abutment fabricated with a 2-degree tapered axial wall, and zirconia crown. The crown of the CL.F system was retained by frictional force between abutment and relined composite resin. In the cement-retained type, zinc oxide eugenolcement was used to set crown and abutment. All specimens were sterilized with ethylene oxide, immersed in Prevotella intermedia culture in a 50 mL tube, and incubated with rotation. After 48 h, the specimens were washed thoroughly before separating the crown and abutment. The bacteria that penetrated into the crownabutment interface were collected by washing with 500 μL of sterile saline. The bacterial cell number was quantified using the agar plate count technique. The BacTiter-Glo Microbial Cell Viability Assay Kit was used tomeasure bacterial adenosine triphosphate (ATP)-bioluminescence, which reflects the bacterial viability. The t-test was performed, and the significance level was set at 5%. RESULTS. The number of penetrating bacterial cells assessed by colony-forming units was approximately 33% lower in the CL.F system than in the cement-retained type (P<.05). ATP-bioluminescence was approximately 41% lower in the CL.F system than in the cementretained type (P<.05). CONCLUSION. The CL.F system is more resistant to bacterial penetration into theabutment-crown interface than the cement-retained type, thereby indicating a precise marginal fit.

Purpose: While initial fixation using a press-fit of the acetabular cup is critical for the durability of the component, restoration of the hip center is regarded as an attributable factor for implant survival and successful outcome. In protrusio acetabuli (PA), obtaining both restoration of the hip center and the press-fit of the acetabular cup simultaneously might be difficult during total hip arthroplasty (THA). We tested the hypothesis that use of a medialized cup, if press-fitted, will not result in compromise of the implant stability and outcome after cementless THA of PA. Materials and Methods: A total of 26 cementless THAs of 22 patients with PA were reviewed. During THA, press-fit of the cup was prioritized rather than hip center restoration. A press-fit was obtained in 24 hips. A pressfit could not be obtained in the two remaining hips; therefore, reinforcement acetabular components were used.Restoration of the hip center was achieved in 17 cups; 15 primary cups and two reinforcement components; it was medialized in nine cups. Implant stability and modified Harris hip score (mHHS) between the two groups were compared at a mean follow-up of 5.1 years (range, 2-16 years). Results: Twenty-six cups; 17 restored cups and nine medialized press-fitted cups, remained stable at the latest follow-up. A similar final mHHS was observed between the restored group and the medialized group (83.6± 12.1 vs 83.8±10.4, P=0.786). Conclusion Implant stability and favorable results were obtained by press-fitted cups, irrespective of hip center restoration. THA in PA patients showed promising clinical and radiological results.
