Cut-out complication remains a major unsolved problem in the treatment of trochanteric hip fractures. A better understanding of the three-dimensional fracture-implant motions is needed to enable further development of clinical strategies and countermeasures. The aim of this clinical study was to characterise and quantify three-dimensional motions between the implant and the bone and between the lag screw and nail of the Gamma nail. Radiostereometry Analysis (RSA) analysis was applied in 20 patients with trochanteric hip fractures treated with an intramedullary nail...

BACKGROUND: Metastatic lesions to the proximal femur occur frequently (about 10% of patients with cancer) and require surgical treatment. There are many surgical methods of treatment, however, use of the tumor modular endoprostheses seems to be particularly promising. The aim of study was to evaluate oncological and functional results of treatment in patients with proximal femur metastases. Oncological results were evaluated considering the survival of patients and the number of local recurrences...

Intertrochanteric fractures are common injuries in the elderly. Conventional intramedullary nails including Gamma 3 locking nail and proximal femoral nail antirotation (PFNA) were designed for unstable intertrochanteric fractures. The InterTan (IT) nail system, introduced in 2005, has been reported superior biomechanical and clinical outcomes compared with 1-screw nailing system. However, some recent studies have reported that IT did not improve functional recovery in patients with intertrochanteric fractures...

BACKGROUND: Breast cancer remains a leading cause of cancer death worldwide. There is evidence that immunotherapy may play a role in the eradication of residual disease. Peptide vaccines for immunotherapy are capable of durable immune memory, but vaccines alone have shown sparse clinical activity against breast cancer to date. Toll-like receptor (TLR) agonists and helper peptides are excellent adjuvants for vaccine immunotherapy and they are examined in this human clinical trial. METHODS: A vaccine consisting of 9 MHC class I-restricted breast cancer-associated peptides (from MAGE-A1, -A3, and -A10, CEA, NY-ESO-1, and HER2 proteins) was combined with a TLR3 agonist, poly-ICLC, along with a helper peptide derived from tetanus toxoid...

INTRODUCTION: This study measured the tip-apex distance (TAD) values in the immediate postoperative period and following weight-bearing and fracture impaction in patients undergoing osteosynthesis with dynamic hip screw and cephalomedullary nail. OBJECTIVE: To correlate the Baumgaertner index in the immediate postoperative period with values obtained after impaction of the fracture with the accommodation of the cephalic implant in the femoral head. PATIENTS AND METHODS: Radiographic TAD measurements were taken with AGFA-VIEW® of 82 patients with a mean age of 72 years with pertrochanteric fractures who were operated on and the fracture fixed with DHS- Synthes® , TFN-Synthes® , or Gamma Nail III-Stryker® in the immediate postoperative period, and following weight-bearing and fracture impaction (mean 3-8 weeks after surgery)...

INTRODUCTION: Anaemia in patients with trochanteric fracture is associated with increased morbidity and mortality and it is an independent risk factor for functional mobility of patients. Several authors have reported the blood loss following operative treatment comparing different fixation systems but few authors have evaluated many associated variables that could influence the perioperative blood loss. PURPOSE: To evaluate the blood loss in patients that had their trochanteric fracture stabilized with dynamic hip screw (DHS) or Gamma nail...

Incontinentia pigmenti (IP) is a rare X-linked dominant disorder, in which skin lesions distributed along Blaschko's lines appear shortly after birth. Early lesions which are erythematous/bullous evolve over time into warty lesions, hyperpigmented swirls/macules, and atrophic hypopigmented streaks. Clinical features are heterogeneous. Abnormalities of the teeth, nails, hair, eyes, central nervous system, and breast may also be present. While intelligence is generally normal, varied degrees of intellectual disability/developmental delay have been reported...

Skeletal involvement is the major clinical complication of multiple myelomas, resulting in pathological fractures. Proximal femoral fractures are very frequent during multiple myeloma evolution and they seriously compromise survival and quality of life of patients with cancer. Early surgical treatment allows mortality and morbidity improvement. Cervicomedullary Gamma locking nail osteosynthesis allows efficient, sustainable and stable fixation associated with early patient mobilization and survival improvement...

Incontinentia pigmenti (IP) is an X-linked genodermatosis affecting the skin and other sites, including the teeth, nails, hair, eyes and nervous system defects in female patients. Generally lethal in males, there are only a few known cases of males surviving this condition. Nuclear factor (NF)-κB essential modulator (NEMO), also known as inhibitor of kappa light polypeptide gene enhancer in B cells, kinase gamma (IKBKG), constitutes an essential activator of NF-κB. Over 80% of female patients with IP carry a common deletion mutation involving exons 4-10 of the IKBKG/NEMO gene...

The ideal implant for the treatment of an unstable intertrochanteric femoral fracture is still a matter of discussion. The aim of this systematic review is to conduct a network meta-analysis of randomized controlled trials (RCTs) comparing clinical outcomes between dynamic hip screws (DHS), Medoff sliding plating, percutaneous compression plating (PCCP), proximal femoral nails (PFN), Gamma nails and less invasive stabilization system fixation in femoral trochanteric fractures in the elderly. These clinical outcomes consist of total intra-operative time, intra-operative fluoroscopy time, intra-operative blood loss, blood component transfusion, length of hospital stay, postoperative general complications, wound complications, late complications and reoperation rates...

Intertrochanteric femur fractures are very common in patients over 65 years old, and are often associated with osteoporosis. Proximal femoral nails are preferred because of their biomechanical advantages in the treatment of these fractures, especially if the fracture is unstable. However, many complications associated with intramedullary fracture fixation have been described. The medial migration of the intramedullary gamma nail is a rare complication. The authors report an uncommon but potentially fatal complication, medial and intrapelvic migration of the intramedullary Gamma 3 nails, recorded after one month of osteosynthesis...
