Modular femoral prostheses are characterized by a second neck-stem junction. This modularity provides many clinical benefits including hip offset restoration, intraoperative leg length and anteversion adjustment. Although, this extra junction in modular femoral prostheses can contribute to catastrophic consequences like fracture, cold welding, corrosion and fretting of the modularity. However, only few complications related to the modularity itself have been reported in the literature. We report a unique case of neck-stem component dissociation without dislocation of the R-120PC™ Modular Stem (DJO Surgical)...

Purpose: Long-term fixation of cemented acetabular components can be problematic in younger active patients. Our technique is put forward to improve outcomes and maximize implant survivorship in this particular patient population. Materials and Methods: We report on a cohort of young adult patients (less than 55 years old) with cemented total hip replacement (THR) using a novel technique in preparing and cementing the acetabulum with a minimum follow-up of 10 years (mean follow-up, 14 years)...

Purpose: Cephalomedullary nails (CMN) are commonly used for the surgical treatment of intertrochanteric fractures. This study aimed to evaluate overall postoperative local complications by reviewing patients who received surgical treatment using three different types of implants. Materials and Methods: The study sample included 353 patients (107 males, 246 females) who underwent surgery using CMN for intertrochanteric fractures. Three different types of implants were used: i) the Gamma3® (Stryker) in 80 cases, ii) the Targon® PF (Aesculap) in 225 cases, and iii) the Compression Hip Nail® (Trademedics) in 48 cases...

Purpose: This 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 Methods: We 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...

Purpose: Although advances in technology have reduced the risk of ceramic implant fractures in total hip arthroplasty, these injuries do occur and their treatment remains challenging. There is a lack of studies reporting on the effectiveness of ceramic components in revision hip arthroplasty after ceramic bearing fracture. The aim of this study is to evaluate clinical and radiologic outcomes of revision surgery with ceramic-on-ceramic components after ceramic bearing fractures in young (i...

Using modular femoral stems in total hip arthroplasty enables surgeons to make fine adjustments to individual joints and offers intraoperative flexibility. The concept of modularity has been developed in numerous shapes, resulting in a vast range of options. Among them, the greatest achievement has been made for prostheses with modular proximal sleeves. The use of these implants has resulted in excellent mid- to long-term results in a number of cases. Although the use of tapered stems with a broaching technique is gaining popularity in straightforward primary surgeries, modular femoral implants are still associated with a number of potential challenges (e...

Periprosthetic joint infection (PJI) is a serious complication after arthroplasty, which is associated with pain, prolonged hospital stay, multiple surgeries, functional incapacitation, and even mortality. Using scientific and efficient management protocol including modern diagnosis and treatment of PJI and eradication of infection is possible in a high percentage of affected patients. In this article, we review the current knowledge in epidemiology, classification, pathogenesis, diagnosis and treatment of PJI...

Gamma 3 rotation control lag screws (U-blade) are particularly useful when treating rotational and unstable fractures of the proximal femur. A 93-year-old woman who underwent closed reduction of a trochanteric fracture and internal fixation with a Gamma 3 nail rotation control lag screw. The patient presented with metal failure and U-blade bending following a fall occurring 4 weeks after surgery. Here, we present a case report summarizing removal of the failed lag screw.

Femoral nerve palsy after total hip arthroplasty is an uncommon complication. We present a case report of delayed-onset femoral nerve palsy associated with iliopsoas hematoma and bursitis 10 years after primary total hip arthroplasty in a 57-year-old male patient with avascular necrosis of the femoral head. The patient visited our clinic due to swelling of the inguinal area with sudden-onset knee extension weakness. Radiologic examination at admission revealed suspicion of bursitis and hematoma on iliopsoas muscle...

The causes of osteolytic lesions found in radiological examinations are not quite certain. Therefore, to determine the appropriate treatment method, various approaches and analyzes are required to find the real cause. Hyperparathyroidism is one of the diseases which forms osteolytic bone lesions so-called brown tumor. A 55-year-old woman who had painful osteolytic bone lesions in both hip joint areas was diagnosed as parathyroid carcinoma after serial work-up. She underwent parathyroidectomy and follow-up imaging showed a decrease in brown tumor size and bone consolidation in the subchondral bone destruction area...

The diagnostic criteria for sequential rapidly destructive coxarthrosis remain unclear and this condition is rarely reported in patients with human immunodeficiency virus (HIV). Here, we report a case of an HIV-infected 73-year old female who experienced hip joint destruction. The patient was diagnosed with HIV in 2012 (at age 68 years) and began continuous treatment with nucleoside reverse transcriptase and protease inhibitors. Twenty-nine months after her HIV diagnosis, the patient experienced osteonecrosis of the right hip and underwent a total hip arthroplasty (THA)...

The long-term use of adefovir and tenofovir-antiviral medications commonly used to treat chronic hepatitis B-can be associated with proximal renal tubular dysfunction resulting in significant hypophosphatemic osteomalacia. However, there have been few reports about pathological fractures requiring surgical stabilization in cases of antiviral drug-induced hypophosphatemic osteomalacia. We present the case of a 51-year-old man who sustained bilateral pathological hip fractures associated with antiviral drug-induced hypophosphatemic osteomalacia...

Purpose: Neurogenic myositis ossificans (NMO) in patients with traumatic spinal cord or brain injuries can cause severe joint ankylosis or compromise neurovascularture. The purpose of this study was to evaluate the clinical and radiological outcomes of and review considerations relevant to surgical resection of NMO of the hip joint. Materials and Methods: Six patients (9 hips) underwent periarticular NMO resection between 2015 and 2017. The medical records of these patients were retrospectively reviewed...

The rate of acetabular cup revision arthroplasty is gradually rising along with an increased risk of osteolysis and prosthesis loosening over time and an increase in life expectancy. The goals of revision total hip arthroplasty are: i) implant stability through reconstruction of large bone defects, ii) restoration of range of motion and biomechanics of the hip joint, and iii) normalization of uneven limb lengths. In acetabular cup revision arthroplasty, stable fixation of acetabular components is difficult in the presence of severe bone loss (e...

Although surgical techniques for treating acetabular fracture are evolving, the use of periacetabular screws is common, and their placement in acetabular surgery is still technically demanding. For instance, intraarticular screw perforation is a serious complication that may occur during surgical treatment of an acetabular fracture. Here, we describe the case of a 50-year-old female who experienced an intraarticular screw perforation after surgical treatment of a posterior acetabular wall fracture. Removal of the perforated screw was performed arthroscopically based on its ability to offer minimally invasive access to the hip joint...
