The lesions on computerized tomography (CT) scan were evaluated in 7 cases of conduction aphasia. On Modified Westem Aphasia Battery (MWAB), all the patients showed fluent aphasia with some paraphasic errors, good comprehension, marked repetition dificit and variable degree of impairment in naming. The three most common lesions on CT scan were supramarginal gyrus and it's white matter, primary auditory cortex, and insular region, which were involved in 6,5,4 cases out of 7 respectively. Of the three lesions, one or variable combinations of them may be the critical structures for repetition difict in these patients, as has been reported in previous studies. In 5 cases Wermicke area was relatively intact and prominent involvement was seen in only 2 cases, which is thought to be associated with relative preseration foaural comprehension in conduction aphasia.

OBJECTIVE: Although anterior cervical discectomy and fusion (ACDF) is the standard treatment for degenerative cervical disc disease, concerns regarding adjacent level degeneration and loss of motion have suggested that arthroplasty may be a better alternative. We have compared clinical and radiological results in patients with cervical disc herniations treated with arthroplasty and ACDF. METHODS: We evaluated 53 patients treated for cervical disc herniations with radiculopathy, 21 of whom underwent arthroplasty and 32 of whom underwent ACDF. Clinical results included the Visual Analogue Scale (VAS) score for upper extremity radiculopathy, neck disability index (NDI), duration of hospital stay and convalescence time. All patients were assessed radiologically by measuring cervical lordosis, segmental lordosis and segmental range-of-movement (ROM) of operated and adjacent disc levels. RESULTS: Mean hospital stay (5.62 vs. 6.26 days, p<0.05) and interval between surgery and return to work (1.10 vs. 2.92 weeks, p<0.05) were significantly shorter in the arthroplasty than in the fusion group. Mean NDI and extremity VAS score improved after 12 months in both groups. Although it was not significant, segmental ROM of adjacent levels was higher in the fusion group than in the arthroplasty group. And, segmental motion of operated levels in arthroplasty group maintained more than preoperative value at last follow up. CONCLUSION: Although clinical results were similar in the two groups, postoperative recovery was significantly shorter in the arthroplasty group. Although it was not significant, ROM of adjacent segments was less in the arthroplasty group. Motion of operated levels in arthroplasty group was preserved at last follow up.

Cutaneous metastasis from internal malignacy is recognized but infrequently occuring manifestation. The prostatic carcinoma rarely acts as a primary source for cutaneous metastasis. We report a case of cutaneous metstasis from prostatic carcinoma. A 82-year-old male presents multiple painless erythematous nodules on suprapubic area, having an episode of surgical removal of prostate carcinoma two years ago. Histologic finding shows atypical anaplastic cell infiltration at the dermis and subcutaneous tissue, forming dermal tumor island, and have features similar to primary prostatic carcinoma. Immunohistochemical staining for prostate specific antigen shows positive reaction within cells, can assist in localization of the metatatic adenocarcinoma to a prostate origin.

PURPOSE: The aim of this study is to investigate the clinical performance and safety of Zimmer® natural nail cephalomedullary nail (ZNN CM nail) in the treatment of proximal femur fractures. MATERIALS AND METHODS: The following research was conducted as a prospective, non-comparative, single center outcome study. Upon providing written informed consent, enrolled patients' data were collected and analyzed. Postoperative follow-up visits were scheduled at 6 weeks, 3 months, 6 months, and 1 year. Follow-up evaluation included radiographic assessment, physical examination, and quality of life and adverse events reports. RESULTS: Thirty-nine patients were available for evaluation at one year postoperative. The patients reported the mean EuroQol-5 Dimension score increased after surgery: from 0.4 points at discharge (n=49) to 0.6 points at 1-year post-surgery (n=39). The mean Harris hip score also increased after surgery: from 56.3 points at discharge (n=49) to 72.1 points at 1 year (n=12). Bone union was seen in 64% (n=16) in 6 months and 95% (n=37) in 1 year. CONCLUSION: The results of this 1-year follow-up study affirmed the effectiveness and safety of the ZNN CM nail in the treatment of proximal femur fractures.

Journal of Bone Metabolism 2021;28(4):333-338
Background:
Low concentrations of vitamin D are considered one of the risk factors for hip fracture and are associated with worse outcomes. The purpose of this retrospective study was to compare vitamin D deficient group and vitamin D sufficient group and assess the association preoperative vitamin D deficiency and postoperative walking ability after hip fracture surgery.
Methods:
Between January 2014 and January 2020, 1,029 elderly patients with hip fracture (243 in men and 785 in women) were measured preoperative serum 25-hydroxy-vitamin D3 levels. Among 1,029 elderly patients, 702 patients were classified as Vitamin D deficient group (<20 ng/mL). Outcome parameters for functional recovery were the length of the hospital stay and KOVAL score, and those for complications were delirium, pneumonia, and thromboembolism.
Results:
The mean length of the hospital stay in the vitamin D deficient group was significantly longer than in the vitamin D sufficient group (27.7±17.8 vs. 2.9±11.8 days; odds ratio [OR], 1.03; 95% confidence interval [CI], 1.02-1.05; P=0.001). The mean postoperative KOVAL score in the deficient group was significantly higher than in the sufficient group (4.0±2.1 vs. 3.1±1.9 days; OR, 1.21; 95% CI, 1.11-1.32; P=0.001). Vitamin D deficiency was significantly associated with a higher risk of delirium and pneumonia in deficiency group.
Conclusions
Preoperative vitamin D deficiency in hip fractures patients was associated with prolonged duration of hospital stay and decrease of postoperative ambulatory status, and may increase the risk of delirium and pneumonia. Therefore, it is necessary to evaluate the preoperative vitamin D level and recommend vitamin D supplementation in elderly patients with a high probability of hip fracture.

Clinics in Orthopedic Surgery 2022;14(4):486-492
Background:
The normal references for acetabular parameters are important for the diagnosis of hip diseases and planning of total hip arthroplasty. There are wide interindividual differences in acetabular morphology in the normal population, and little is known about differences in acetabular morphology in the average South Korean population. The purpose of this study was to evaluate side and sex differences in acetabular morphology in the South Korean population.
Methods:
The acetabular parameters, including anteversion angle, abduction angle, center-edge angle, acetabular width and depth, and acetabular-head index, were measured on three-dimensional computed tomography images in 197 healthy Korean adults. Differences in acetabular parameters according to side and sex were evaluated.
Results:
The mean acetabular anteversion angle of men and women was 17.3° ± 5.2° and 20.1° ± 3.5°, respectively. The mean acetabular width of men and women was 61.5 ± 4.6 cm and 56.5 ± 4.0 cm, respectively. There were significant sex differences in acetabular anteversion angle (p = 0.001) and acetabular width (p = 0.036) when adjusted for age, body height, and weight. The mean acetabular width of the right side and the left side was 60.2 ± 5.2 cm and 57.8 ± 4.5 cm, respectively. There were significant side differences in acetabular width (p = 0.007) when adjusted for age, body height, weight, and sex.
Conclusions
Differences and reference ranges of acetabular parameters are important for the diagnosis of acetabular deformity, such as femoroacetabular impingement and acetabular dysplasia. Moreover, these differences and reference ranges are useful for preoperative planning and safe positioning of acetabular components in total hip arthroplasty.
