Hip Arthroplasty Using the Bencox® Hip System: An Evaluation of a Consecutive Series of One Thousand Cases / 대한고관절학회지

PURPOSE: This is a report on the outcomes associated with a consecutive series of 1,000 cementless hip arthroplasties utilizing the Bencox® hip stem–the first Korean-developed hip prosthesis. MATERIALS AND METHODS: A consecutive series of 1,000 hip arthroplasties using the Bencox® hip stem were analyzed, starting from its initial release (September 2006) until June 2014. Patients in this consecutive series underwent surgery for fractures (n=552), arthritis (n=155), avascular necrosis (n=209), and revisions (n=84). Of these 1,000 cases, patients with a minimum follow-up of at least 1 year (n=616) were retrospectively analyzed for radiographic and clinical outcomes (i.e., Harris hip score). The stability of the prosthesis was evaluated by examining subsidence. RESULTS: During the follow-up period (mean follow-up period of 54.8 months), there were 2 cases requiring revision of the femoral stem–both were caused by periprosthetic fractures and neither involved stem loosening. The mean Harris hip score during follow-up was 95.5. Bone ongrowth occurred in 95% of patients; no cases of subsidence or aseptic loosening of the stem were detected, and no cases of postoperative complications such as ceramic breakage were observed. CONCLUSION: Clinical and radiographic evaluations of hip arthroplasty using the Bencox® hip stem revealed excellent outcomes with an average of 54.8 month follow-up in a consecutive series of 1,000 cases.

Juxta-articular Plate Fixation in Distal Radius Intra-articular Fractures with Accompanying Volar Free Fragments beyond the Watershed Line

BACKGROUND: Although distal radius fractures (DRF) are common fractures, intra-articular comminuted DRF with volar free fragments are uncommon. There is considerable difficulty in the fixation of free fragments beyond the watershed line using the existing volar locking plate. We aimed to examine the efficacy and potential complications associated with the use of juxta-articular volar plates in intra-articular DRF accompanied by free fragments beyond the watershed line. METHODS: The patients were enrolled in a consecutive manner between 2007 and 2016. In cases of DRF with free fragments beyond the watershed line, we employed a 2.4-mm small fragment juxta-articular volar locking compression plate using a volar Henry approach. A total of 32 patients were included in this study. There were 15 males and 17 females with a mean age of 52.3 years (range, 33 to 69 years). The mean follow-up period was 14.5 months (range, 10 to 24 months). Preoperative radiographs and three-dimensional computed tomography images were used to analyze fracture patterns and assess the free fragments beyond the watershed line. The mean number of free fracture fragments beyond the watershed line was 2.33. Plain radiographs of immediate postoperative and last follow-up were used to confirm fracture union, incongruence, radial height, volar tilt, radial inclination, and arthritic changes. For functional assessment, we measured grip strength, range of motion (ROM), modified Mayo wrist score (MMWS) and determined Disabilities of Arm, Shoulder and Hand (DASH) scores at the last follow-up. Postoperative complications were monitored during the follow-up period. RESULTS: All patients obtained sound union without significant complications. At the last follow-up, 16 cases presented with an articular step-off of more than 1 mm (mean, 1.10 mm). The mean MMWS was 76.3 (range, 55 to 90), mean DASH score was 15.38 (range, 9 to 22), mean visual analogue scale score for pain was 1.2 and mean grip strength was 75.5% of the opposite side. The mean ROM was 74.3° for volar flexion and 71.5° for dorsiflexion. CONCLUSIONS: In cases of intra-articular DRF with free fragments beyond the watershed line, a volar approach with use of a juxtaarticular plate provided favorable outcomes without significant complications.

Educational Needs of Toddler's Mother in Child-caring Experience / 아동간호학회지

The purpose of this study was to find educational needs of toddler's mother in child-caring experience. The subject of the study was toddler's mother who visited one health care center in J city for immunization and had a child or children between twelve and thirty six months old. The subjects were 37 mothers. The instrument used for this study was a semi-structured questionnaire developed by researcher and based on Objective Content Test of Garretson(1967). The Collected data were analized by two researchers using the method of content Analysis. The results of this study are summarized as follows ; 1) Of the large categories, the need of the highest frequency was 'prevention and management of disease and injury', that of the lowest 'growth and development'. 2) In 'physical care' category, 'care of sleeping' was the highest. In 'nutrition and eating-habitual management' category, 'weaning management' was the highest. In 'prevention and management of disease and injury' category, 'disease management' was the highest. In 'discipline and teaching' category, 'discipline' was the highest. 3) In comparison with preceding references, the educational needs of child-caring which had not been shown in preceding references but had been shown in this study were hair-caring, kind of weaning diet, method of cure and nursing, management of deformity, and so on. In conclusion, educational needs of toddler's mother in child-caring experience were matter-of-fact and inclusive. Needs in management of special situation such as disease were higher than usual parenting procedure or method. In addition, there were higher needs in questions happened through child-caring experience or confirmation of procedures practicing now. Then, it is suggested that parent education program should be developed on the basis of educational needs found in this study to be more effective in preparing mothers's child-caring.
