“…Other studies have reported similar results15171819). In contrast, early postoperative subsidence of the stem has been reported in many studies of the cementless Spotorno stem (CLS stem; Zimmer, Warsaw, IN, USA), whose design is similar to that of the COREN prosthesis202122).…”

PurposeThis study presents the clinical and radiological outcomes of cementless total hip arthroplasty using the COREN hip system after a minimum duration of follow-up of 5 years.Materials and MethodsWe evaluated the results of a consecutive series of the first 200 primary total hip arthroplasties that had been performed in our hospital in 169 patients between February 2007 and April 2011. Six patients (6 hips) had died within 5 years, and 12 patients (13 hips) had been lost to follow-up, leaving a total of 151 patients (181 hips) available for the study. All patients were evaluated clinically and radiologically with special attention to thigh pain, implant fixation, radiolucent line and osteolysis around implants.ResultsThe mean Harris hip score improved from 59.4 preoperatively to 97.2 postoperatively. No patient complained of thigh pain. All implants demonstrated radiographic evidence of stable fixation by bone ingrowth without any change in position. No implant was loose radiographically or was revised. Eleven hips (7.7%) had a radiolucent line around the femoral stem. Focal osteolytic area was detected in 3 cases (2.1%). An osteolytic lesion was stabilized in 1 case and further observation was needed in 2 cases in which the lesions were detected several years after surgery. Stress shielding was observed in 80.3% of cases (first degree, 35.9%; second degree, 44.4%); there were no cases of third or fourth degree stress shielding. One case was complicated by bacterial infection and repeated dislocation.ConclusionMid-term results of total hip arthroplasty using the COREN hip system are very encouraging clinically and radiologically.

“…Although the use of a cemented stem has been proposed to solve this problem 20 21 22) , this is limitedly used because of a high mortality risk caused by fat embolism, cement embolism, vasodilation due to autonomic reflex and others in elderly patients with cardiovascular diseases 23) . We ensured solid fixation by using a cementless, double tapered, rectangular wedge-shaped, straight stem (Bencox®), and obtained excellent clinical and radiographic results at 2-year follow up 24 25) .…”

PurposeFemoral intertrochanteric fractures are common in the elderly. Appropriate surgical fixation of trochanteric fracture fragments can restore normal anatomical structure and ambulation, and can aid in the recovery of biomechanical function of the hip. We evaluated clinical outcomes of bipolar hemiarthroplasty using a wiring technique for trochanteric fracture fragment fixation.Materials and MethodsFrom September 2006 to February 2015, a total of 260 cases underwent simultaneous bipolar hemiarthroplasty and wire fixation. A total of 65 patients (69 hips) with an average age of 78 years and more than one year of follow-up was included in the study. Using pre-, postoperative and follow-up radiograms, we evaluated wire fixation failure and also assessed changes in walking ability.ResultsLoosening or osteolysis around the stem was not observed; however, we did observe bone growth around the stem (54 cases), cortical hypertrophy (6 cases), a wide range of sclerotic lines but no stem subsidence (1 case), wire breakage (9 cases), and fracture fragment migration with no significant functional deficiency (2 cases).ConclusionOur study showed that additional wiring for trochanteric fracture fragment fixation following bipolar hemiarthroplasty can help restore normal anatomy. The added stability results in faster rehabilitation, and good clinical and radiographic outcomes. We recommend this procedure in this type of fracture.

“…Moreover, bony ongrowth was shown in 95.0% of patients (585 of 616 cases) with follow up for at least one year. Our previous 5-year follow-up study revealed good results of the Bencox® stem (e.g., excellent bone ongrowth rates [86.6% in the fracture group, 99.6% in the OA group without subsidence or complications requiring revision operation]) 19) . In another study, 78% of patients with an unstable intertrochanteric fracture experienced restoration of their ambulation ability to a pre-injury state, and the combined use of wiring fixation has been described to help obtain support in the posterolateral aspect including the lesser trochanter 5 10) .…”

PurposeThis 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 MethodsA 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.ResultsDuring 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.ConclusionClinical 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.
