Introduction: The original Harris hip score (HHS) does not contain ability to perform squatting and sitting cross legged as items in the questionnaire and hence a need was felt to modify the Harris hip score so that it could stay relevant in functional assessment of Indian patients in the rural setting. Validity, responsiveness and ceiling floor effect of the Harris hip score after internal fixation of pertrochanteric fracture has not been previously described. The objective of the study was to investigate construct validity, responsiveness and ceiling floor effects of the modified Harris hip score (mHHS)...

Background: Basicervical proximal femoral fracture is a known subtype of extracapsular fracture and is mechanically unstable, especially for the rotational direction, which may lead to implant failure. A cephalomedullary nail (CMN) is widely used for the fixation of unstable extracapsular fracture; however, its application for basicervical fracture remains controversial. Helical blade CMN is proven to have more rotational stability than traditional lag screw implants and potentially advantageous in the treatment of basicervical fracture...

Complication rates of hip fractures after proximal femoral nail are not rare. In such fractures, treatment invariably comprises the extraction of proximal femoral nail and the introduction of a different hip prosthesis. To solve this problem, we aimed to develop a new implant, the modular nail prosthesis, which combines an intramedullary nail with a hip prosthesis. The aim of this study was to determine the effect of stress load distribution on the stem using finite element analysis under laboratory conditions...

BACKGROUND: Cut-out is the most common mechanical complication of the osteosynthesis of pertrochanteric fractures. This complication determines a significant increase in morbidity in elderly patient. Cut-out is defined as the varus collapse of the femoral head-neck fragment with the extrusion of the cephalic screw. Surgical treatment of cut-out might lead to further complications, longer rehabilitation, increased social burden and healthcare system costs. The aim of the study is to identify the predictors of cut-out to prevent its occurrence...

Introduction: Clavicle fractures are common injuries treated by orthopedic surgeons, with most injuries managed nonoperatively. Operative fixation of clavicle fractures is indicated in specific clinical scenarios such as open injuries, ipsilateral shoulder trauma, or fractures with associated neurovasculature compromise. Operative fixation is not widely accepted for closed injuries and is typically reserved for instances of failed closed treatment with resultant nonunion or delayed union...

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...

INTRODUCTION: In many low and middle-income countries (LMICs) SIGN nail is commonly used for antegrade femoral intramedullary (IM) nailing, using a start site either at the tip of the greater trochanter or piriformis fossa. While a correct start site is considered an essential technical step; few studies have evaluated the impact of using an erroneous start site. This is particularly relevant in settings with limited access to fluoroscopy to aid in creating a nail entry point. The purpose of this study was to evaluate the impact of antegrade SIGN IM nailing start site on radiographic alignment and health-related quality of life...

Intramedullary nailing (IM) is a technique universally accepted to treat femoral diaphyseal fractures. The treatment of fractures located in the distal third remains a controversial issue though. A finite element model of the femur has been developed, analyzing distal fractures with several gap sizes combined with different interlocking combinations of distal screws with one oblique screw proximally to stabilize the intramedullary nail. The mechanical strength of the nail against bending and compression efforts was also studied...

Femoral shaft fractures are among the most severe injuries of the skeleton. They are associated with high morbidity and mortality. The most appropriate treatment depending on the type of fracture and location level should be chosen. A finite element model of the femur has been developed, analyzing various types of fractures in the subtrochanteric and diaphyseal supracondylar area, with several gap sizes, being stabilized with a single combination of screws for the intramedullary nail. The mechanical strength of the nail against bending and compression efforts was studied comparing two materials for the nail: stainless steel and titanium alloy...

OBJECTIVE: Femoral intertrochanteric fractures are usually fixed with short, straight cephalomedullary nails. However, mismatches between the nail and the femur frequently occur, such as tip impingement and tail protrusion. The authors designed a new type of short femoral intertrochanteric nail (fitn) with an anterior curvature (length=19.5cm, r=120cm) and herein report the geometric match study for the first of 50 cases. METHODS: A prospective case series of 50 geriatric patients suffering from unstable intertrochanteric fractures (AO/OTA 31 A2/3) were treated...

BACKGROUND Poliomyelitis is a neuromuscular disease which causes muscle atrophy, skeletal deformities, and disabilities. Treatment of hip fractures on polio-affect limbs is unique and difficult, since routine fixation methods like nailing may not be suitable due to abnormal skeletal structures. CASE REPORT We report one femoral neck fracture and one subtrochanteric fracture in polio survivors successfully treated with reverse less invasive stabilization system (LISS) plating technique. Both fractures were on polio-affected limbs with significant skeletal deformities and low bone density...
