In the elderly patients who complain of pain in the buttock and leg, it is not easy to distinguish whether the pain comes from the lesion of the hip or from the spine. A 78-year-old female who was treated conservatively for persistent pain in the right buttock and leg after an operation for spinal stenosis in the local clinic visited our clinic. Septic hip arthritis with severe femoral head destruction and multiple abscesses in the buttock and iliopsoas muscle were diagnosed 2 months postoperatively, and spinal abscess in the site of the previous operation was detected by a subsequent MRI study. To avoid such a delay of the diagnosis and treatment, it is important to suspect hip joint lesion earlier for the source of persistent pain after a spine operation. Further more, diagnostic evaluation is necessary to rule out co-infection of the spine or iliopsoas muscle when a hip joint infection exists.

A non-traumatic, incomplete insufficiency fracture commonly involves the lateral side of the femoral cortex; whereas a non-traumatic, incomplete stress fracture commonly involves the medial side of the femoral cortex. Here, we describe a case of a 66-year-old woman with a two-month history of bilateral thigh pain without trauma or medication usage who was diagnosed with bilateral subtrochanteric insufficiency fractures involving the medial side of the femoral cortex.

Periprosthetic joint infection is one of the most dreaded complications of replacement arthroplasty and the incidence of periprosthetic tuberculous infections is increasing. This report presents a case of extensive periprosthetic tuberculous infections of primary total hip arthroplasty which was treated with debridement and long periods of antituberculous medication without implant removal. The patient completed 18 months of 4 drug antituberculous chemotherapy and the plain radiograph on the last review showed new bony consolidation around the prosthesis without loosening or signs of reactivation.

This is a report of 2 cases that showed dissociation of the acetabular cup liner by acetabular fixation screw among patients who underwent total hip replacement. Screws for fixation of the acetabular cup were used during the primary surgery in both cases. Each patient visited the out patient department complaining of pain and noise from the joint; radiologic finding revealed a collapse of the column shape bone graft area with dissociation of the acetabular cup liner. In both cases, during revision surgery, screw was extruded to the inner side of the acetabular cup, since it migrated superiorly. There has been no report of liner dissociation by extrusion of acetabular cup fixation screw after total hip replacement. Therefore, we report two cases of dissociation of the acetabular cup liner of hip arthroplasty, which occurred due to screw issues after total hip replacement with structural autogenous bone graft.

PURPOSE: The purpose of this study is to compare and analyze the radiological and clinical results after treatment of intertrochanteric fractures of the femur by three devices including DLT, PFNA and Gamma 3 nail. MATERIALS AND METHODS: From January 2007 to January 2012, we reviewed 131 patients who suffered intertrochanteric fractures(33 cases of DLT, 59 cases of PFNA, 39 cases of Gamma 3 nail). The following were measured for all three groups; The tip apex distance (TAD), neck shaft angle and lag screw position at the head of femur, as well as the amount of blood loss and transfusion, operation time, duration of hospitalization and postoperative ICU admission, complications were also assessed. RESULTS: In comparison of the radiological results, there were no statistical differences among the three groups in TAD, neck shaft angle and the lag screw position. There was no statistical difference in clinical results. In the last follow-up, there was one case of nonunion in the PFNA group. There also was, in the last follow up, a development of varus angulation & cut-out of lag screw that occurred in 2 cases (DLT), 4 cases (PFNA), 1 cases (Gamma 3). There was no statistical difference among the three groups in the sliding length of the lag screw. CONCLUSION: Any certain group was not better than the others with regard to the radiological and clinical results among DLT, PFNA and Gamma nail groups in treating intertrochanteric fracture. To achieve favorable results, precise reduction of fracture site and surgical techniques are important.

PURPOSE: The purpose of this study is to evaluate the results of bipolar hemiarthroplasty using calcar replacement stem for comminuted intertrochanteric fracture in elderly patients. MATERIALS AND METHODS: Between March 1998 and March 2008, the clinical records of 79 cases who were older than 75 years of age and underwent bipolar hemiarthroplaty, using calcar replacement stem with figure of eight and cerclage wiring, were reviewed. Their mean age was 82.4 years(75-92 years) and the mean follow-up period was 68 months(24-92 months). RESULTS: The mean postoperative Harris hip score was 82.1(62-92), and preoperative walking ability was recovered in 56 cases(71%). Bony ingrowth fixation was achieved in 70 cases(89%), and fibrous stable fixation was in 9 cases(11%). Stress shields were revealed in 21 cases(27%). Nonunion of trochanter was found in 3 cases(4%), and wire fixation breakages were in 3 cases after bony union. The mean duration of bony union was 16.3 weeks(12-38 weeks). Aseptic loosening was observed in 1 case and protrusio acetabuli were in 2 cases. CONCLUSION: The result of clinical and radiological evaluations of bipolar hemiarthroplasty, using calcar replacement stem with figure of eight and cerclage wiring, were satisfactory in elderly patients with comminuted intertrochanteric fracture.

PURPOSE: To analyze the clinical and radiological outcomes of total hip replacement arthroplasty (THRA) for the treatment of femur neck fractures in the elderly. MATERIALS AND METHODS: Femur neck fracture patients older than70 years of age, who showed good preoperative walking ability without dementia,and underwent THRA between February, 2008 and March, 2010 were reviewed retrospectively. Twelve patients(13 hips) were enrolled and the mean ages of the patients were 79.4(70-91). The mean follow-up period was 31(20-49) months. The modified Koval index was used to determine the clinical outcome. Inclination and anteversion of acetabular cup, loosening, osteolysis, periprosthetic fractures and dislocations were evaluated using the radiographs. RESULTS: The modified Koval index decreased from 4.92 to 4.84 at the final follow-up, but the decrease was not significant (P=0.339). Dislocations occurred in 2 cases postoperatively(2/13, 15.4%). No other complications were encountered. CONCLUSION: The THRA for the treatment of femur neck fractures in elderly patients over 70 years of age showed satisfactory clinical and radiological outcomes. Nevertheless, caution should be taken regarding the relatively high incidence of postoperative dislocations.

PURPOSE: This study evaluated the usefulness of ultrasonography for a diagnosis of acetabular labral tear in femoroacetabular impingement (FAI). MATERIALS AND METHODS: From March 2010 to October 2011, an ultrasonographic examination was performed in 58 patients(58 hips: 26 men and 32 women) with acetabular labral tear. The sensitivity and positive predictive value of ultrasonography were evaluated for 58 cases with acetabular labral tear confirmed by hip arthroscopy. RESULTS: The sensitivity and positive predictive value for an acetabular labral tear using ultrasonography was 89.6% and 100%, respectively. The concordance rate of an acetabular labral tear between arthroscopy and ultrasonography was 84.6%. CONCLUSION: Hip ultrasonography can make a significant contribution to a pathologic diagnosis and isa useful diagnostic tool for acetabular labral tears.

PURPOSE: This study examined the association between the pre-operative body mass index (BMI) and the post total hip replacement arthroplasty result, as well as postoperative change in the life quality of patients diagnosed with femur head avascular necrosis (AVN). MATERIALS AND METHODS: Patients diagnosed with femur head AVN undergoing total hiparthroplasty (THA) with a ceramic-ceramic articular surface from March 2005 to May 2011 were analyzed retrospectively. The Harris hip score (HHS), 36-item short-form health survey (SF-36) score, radiological examination, and complications at two years or longer after THA in the 4 groups were analyzed in terms of the BMI (underweight group, normal weight group, overweight group, and obesity group). RESULTS: The normal body weight group showed the best result(94.36+/-7.51) in all scores but the difference was not significant. In the SF-36 physical scores, obese group showed the greatest improvement. Complications occurred frequently in the underweight(50%) and obese groups(19.5%). In particular, periprosthetic fractures (P=0.002) and pneumonia (P=0.005) occurred frequently in the underweight group. CONCLUSION: The impacts of obesity and underweight on the clinical outcome after surgery are insignificant but patients with an abnormal BMI can expect a high quality of life after surgery.

PURPOSE: We previously reported results of a mean 3.2-year follow-up of the COREN hip system, which is the first total hip prosthesis developed in Korea. The aim of this prospective study was to update the previous report with regard to the hip function and radiographic implant performance. MATERIALS AND METHODS: Between 2003 and 2004, a consecutive series of 68 primary, cementless, total hip prostheses (COREN) were implanted in 57 patients(68 hips) and followed up for a minimum of 7 years. Sixty-three of the 68 hips were available for clinical scoring and radiographic analysis. RESULTS: The mean Harris hip and WOMAC scores were improved from 48.1 and 54.7, preoperatively, to 96.4 and 22.1 at the final follow-up. The mean patient activity increased from 3.1, preoperatively, to 8.2 at the final follow-up. All hips showed stable bony ingrowth on the radiographs. No hips showed evidence of osteolysis or prosthesis loosening, and no revision was required during the follow-up. A Periprosthetic fracture (Vancouver type B1) was encountered in one hip 4.7 years after surgery, which was treated by reoperation. CONCLUSION: This study shows that the COREN hip system produces excellent mid-term results in cementless hip arthroplasty.
