Materials and Methods: Thirty-three PE liner changes were performed without the removal of stably ingrown implants (33 hips of 32 patients). They were able to be followed for a mean period of 92 months. Clinically, the Harris hip score (HHS), pain evaluation, and complications were evaluated. Radiologically, the annual wear rate and the size of the osteolytic lesions were measured before the operation and the latest follow-up. The bone graft incorporation scale and the development of new osleolytic lesions were checked during the final follow-up. Results: HHS improved to 89.3 at last follow-up. The size of the osteolysis was significantly reduced postoperatively. Bone graft incorporation scales were Grade I in 9 and Grade II in 14 cases. New osteolytic lesions have not developed at latest follow-up. As a complication, one case of dissociation of a liner and a periprosthetic fracture were noted. Annual wear rates during the same period were significantly reduced. There was no sign of alteration in stability of the PE liner. Conclusion: Exchange of a PE liner without removal of stable implants can be a good option for the treatment of wear and osteolysis around a stable cementless THA implant, even if the system has a weak locking mechanism, such as the HG cup. In these cases, under certain states with a higher risk of early failure in the locking mechanism, it would be better to select other revision procedures such as cup revision or cemented polyethylene liner fixation.","PeriodicalId":410202,"journal":{"name":"The Journal of the Korean Hip Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126872855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: A total of 230 patients were enrolled who had all experienced a femoral intertrochanteric fracture and undergone the Proximal Femoral Nail Anti-rotation surgical procedure between February 2007 and April 2011. We measured the neck-shaft angle and endosteal width at the isthmus of a normal femur, and the distance between the greater trochanter and the nail tip of the Proximal Femoral Nail Anti-rotation in post-operative plain radiography. We analyzed the average and standard deviations of the measurements. We also investigated correlations with the patient gender. Results: The average neck-shaft angle and endosteal width at the isthmus were 129.7。(111.0~138.3。 ) and 14.5 mm (9.7~23.1 mm), respectively. The average protruded nail length was 4.9 mm (1.0~15.0 mm). The femur neck-shaft angle had a correlation ratio with gender (p=0.000). However, the endosteal width at the isthmus level and the protruded nail length had no correlation ratio with gender (p=0.108, 0.573, respectively). Conclusion: Until now, in intertrochanteric fracture operations using Proximal Femoral Nail Anti-rotation, the selection of devices has been extremely limited. Through this study we present the average Korean anatomical neckshaft angle, endosteal width of the femur, and protruding length of the nail tip. We expect that these numerical values can be used in the production of new devices with shorter proximal nails, which would be more appropriates for Koreans.","PeriodicalId":410202,"journal":{"name":"The Journal of the Korean Hip Society","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125938951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bone stock deficiency presents the major challenge in acetabular reconstruction during revision hip arthroplasty. The reasons for such acetabular defects include osteolysis, bone resportion following cup loosening, iatrogenic damage resulting from cup or cement removal during revision THA, and cup migration. The pre-operative assessment of acetabular bone stock, including the amount and location of pelvic osteolysis before revision surgery, is a critical preoperative preparation for the treatment of bone deficiency. In cases with mild acetabular defects, a variety of surgical options are available for treating. However, in cases with severe segmental, cavitary, or combined acetabular defects, controversies have existed so far about the most optimal treatment. Thereby, we tend to introduce the most commonly-adopted classification system of acetabular defects and management options using high hip center cups, oblong cups, structural allografts, morselized allografts with bipolar cups, morselized allografts with cementless cups, morselized allografts with acetabular reinforcement devices, and revisions with trabecular metal augmentations.","PeriodicalId":410202,"journal":{"name":"The Journal of the Korean Hip Society","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129284181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A leg length discrepancy is the difference in vertical distance between a horizontal line drawn along the bottom of the ischial tuberosities and the most inferior points of the lesser trochanter. It was measured in a pelvis AP x-ray. In each case, pre-operative templating was performed and an intraoperative pelvis AP x-ray was taken again to assess the accuracy of preoperative planning. Implant positions were readjusted when necessary. Results: The mean post-operative leg-length discrepancy was 0.3 mm (SD, 3.1 mm). The range was from -5.8 mm to +5.9 mm.

The purpose of this study was to evaluate the midterm effect of ceramic-on-ceramic bearing THA using cemented femoral stems. Materials and Methods: We studied 32cases (30 patients) of THA using ceramic-on-ceramic bearing cemented femoral stems and 33 cases (31 patients) of THA using ceramic-on-ceramic bearing cementless femoral stems. All total hip arthroplasties were performed between January 2004 and December 2005 and were followed up for more than 5 years. The clinical results and radiographic results were evaluated. Results: The mean HHS improved from points pre-operatively to points at the last follow-up in both the cemented and cementless stem groups (P<0.05). The mean WOMAC score also improved from points pre-operatively to points at the last follow-up in both the cemented and cementless stem groups (P<0.05). But no statistically significant difference was noted between the cemented and cementless stem groups in HHS and WOMAC scores (P=0.304, P=0.769). There were 3 patients with a sense of discomfort on ambulation and 5 patients with thigh pain in the cementless stem group and no cases in the cemented stem group. There was no instance of acetabular loosening in either group. Subsidenc of the cemented femoral stem was less than 1mm in 30 cases and less than 2 mm in 2 cases. All cementless femoral stems acquired firm bony union.
