PurposeIn comminuted intertrochanteric fractures, various operative options have been introduced. The purpose of this study was to determine whether there were differences in clinical and radiologic outcomes among bipolar hemiarthroplasty (BH), compression hip screw (CHS) and proximal femur nail antirotation (PFNA) in treating comminuted intertrochanteric fractures (AO/OTA classification, A2 [22, 23])Materials and MethodsWe retrospectively evaluated total 150 patients (BH, 50; CHS, 50; PFNA, 50) who were operated due to intertrochanteric fractures from March 2010 to December 2012 and were older than 65 years at the time of surgery. We compared these three groups for radiologic and clinical outcomes at 12 months postoperatively, including Harris Hip Score, mobility (Koval stage), visual analogue scale and radiologic limb length discrepancy (shortening).ResultsThere was no statistical significance among three groups in clinical outcomes including Harris Hip Score, mobility (Koval stage), visual analogue scale. However, there was significant differences in radiologic limb discrepancy in plain radiographs at 12 months postoperatively (radiologic shortening: BH, 2.3 mm; CHS, 5.1 mm; PFNA, 3.0 mm; P=0.000).ConclusionThere were no clinical differences among BH, PFNA, and CHS in this study. However, notable limb length shortening could be originated during fracture healing in osteosynthesis, compared to arthroplasty (BH

Total joint arthroplasty could be done without transfusion using this protocol in most of our patients. The rates of infection and mortality were similar with known infection and mortality rates of arthroplasties. In patients who do not want allogeneic transfusions, our protocol is a safe alternative to perform joint arthroplasties.

The aim of this study was to investigate survival rate, complications and associated risk factors after hip fracture surgery in patients with chronic kidney disease (CKD) by comparing to non-CKD patients. A total of 119 patients (130 hips, 63 hips CKD group, 67 hips non-CKD) who underwent hip fracture surgery were included. We assessed variables including age, gender, CKD, comorbidities, operation delay and operation time as risk factors for survival and complications after hip fracture surgery. The survival rate was 55.8% at 1-year, 45.8% at 3-year, and 31.4% at 5-year in CKD group, whereas 82.1%, 60.7%, and 36.8%, respectively in non-CKD. Age (more than 85) (hazard ratio [HR], 3.238; 95% confidence interval [CI], 1.736–6.042; P < 0.001), stages 4, 5 of CKD (HR, 2.004; 95% CI, 1.170–3.433; P = 0.001), cerebrovascular disease (HR, 2.213; 95% CI, 1.196–4.095; P = 0.001), and malignancy (HR, 3.086; 95% CI, 1.553–6.129; P = 0.001) were significant risk factors. Complications occurred in 17 hips of CKD group and 8 hips of non-CKD. Stage 4–5 of CKD (odds ratio [OR], 3.401; 95% CI, 1.354–8.540; P = 0.001), malignancy (OR, 3.184; 95% CI, 0.984–10.301; P = 0.050) were significant risk factor. When performing hip fracture surgery in patients with CKD, surgeons should consider age, severity of CKD, and presence of other comorbid disease, such as cerebrovascular disease and malignancy, as patients with these risk factors will need more intensive preoperative and postoperative care.

Purpose: The aim of this study was to determine the mortality and factors that are related to the mortality in elderly patients with hip fracture. Materials and Methods: Between March 2006 and December 2009, 304 patients who were 65 years or older underwent surgery for hip fracture. Among them, 261 patients were available and 43 patients excluded from this study, as they were unable to be evaluated for one year mortality. We analyzed the relationship between the postoperative mortality and the associated factors (age, gender, the type of operation, the type of fracture, method of anesthesia, comorbidity, operation delay). Results: The one year mortality rate for elderly patients with hip fracture was 10.7%. There was no relationships between the postoperative mortality and the type of operation, the type of fracture, and method of anesthesia. However, age, gender, the number of comorbidity, operation delay, and dementia of comorbidity were factors associated with the mortality rate for elderly patients with hip fracture. Conclusion: The one year mortality rate for elderly patients with hip fracture was 10.7%. Age, gender, the number of comorbidity, operation delay, and dementia of comorbidity were factors associated with the mortality rate in elderly patients with hip fracture.

ObjectiveThe aim of this study was to evaluate the radiologic outcomes of open reduction and lateral plating with wiring in the treatment of Vancouver B2 periprosthetic femoral fractures.MethodsWe retrospectively recruited 37 patients treated with ORIF with lateral plating and wiring for Vancouver B2 fractures. The 27 patients (15 men and 12 women; mean age: 70.8 ± 8.3 years) without follow-up loss had achieved complete bony union without notable complications. The average union period was checked after operation with radiologic findings. Radiologic outcomes were evaluated by ipsilateral limb length discrepancy (LLD) and subsidence between immediate postoperative length and length at postoperative 1 year after adjusting for magnification differences. The average distance to which the retained stem sunk down was investigated between immediate postoperative radiographs and final radiographs showing union.ResultsTen patients could not be evaluated, because of mortality or failure to follow up. The average time to union was 18.3 weeks, and the average distance of stem sinking was 2.5 ± 1.7 mm (range: 0–7.2 mm), which was significantly different between immediate postoperative radiographs and final radiographs. There was no case with loss of reduction or loss of fixation, requiring revision surgery.ConclusionOpen reduction and lateral plating with wiring as a treatment for Vancouver B2 periprosthetic femoral fractures produced good radiologic outcomes with successful bony union. ORIF can be considered the alternative option for treating patients with Vancouver B2 PPF, instead of stem revision surgery.Level of evidenceLevel IV, Therapeutic study.

Periprosthetic fractures after total knee arthroplasty (TKA) are gradually increasing, reflecting extended lifespan, osteoporosis, and the increasing proportion of the elderly during the past decade. Supracondylar periprosthetic femoral fracture is a potential complication after TKA. Generally, open reduction and internal fixation are the conventional option for periprosthetic fracture after TKA. However, the presence of severe comminution with component loosening can cause failure of internal fixation. Although the current concept for periprosthetic fracture is open reduction and internal fixation, we introduce an unusual case of revision arthroplasty using a MUTARS® prosthesis for a comminuted periprosthetic fracture in the distal femur after TKA, with technical tips.

Revision rates of total hip arthroplasty have decreased after introducing total hip arthroplasty (THA) using ceramic component, since ceramic components could reduce components wear and osteolysis. The fracture of a ceramic component is a rare but potentially serious event. Thus, ceramic on polyethylene articulation is gradually spotlighted to reduce ceramic component fracture. There are a few recent reports of ceramic head fracture with polyethylene liner. Herein, we describe a case of a ceramic head component fracture with polyethylene liner. The fractured ceramic head was 28 mm short neck with conventional polyethylene liner. We treated the patient by total revision arthroplasty using 4th generation ceramic on ceramic components.
