The spectrum of femoral shaft fractures is wide and ranges from nondisplaced stress fractures to fractures associated with severe comminution and significant soft tissue injury. Femoral shaft fractures are generally caused by high-energy forces and are often associated with multisystem trauma. Isolated injuries can occur with repetitive stress and may...

Stress fractures are overuse injuries of bone. These fractures, which may be nascent or complete, result from repetitive subthreshold loading that, over time, exceeds the bone's intrinsic ability to repair itself. Briefhaupt originally described stress fractures in military recruits in 1855. Our present understanding of the pathophysiology of stress fractures...

Abstract (full text available) Background It has been suggested that a hip fracture as a primary diagnosis for arthroplasty is a risk factor for periprosthetic fracture.
Patients and methods We compared 16 patients with late periprosthetic fracture of the femur to 48 controls. The primary diagnosis for all patients was hip...

Management of Pathological Fracture Neck of the Femur Following Recent Osteomyelitis in a Child A S Devnani
ABSTRACT Fracture neck of the femur is rare in children and occurs following severe trauma(1-5). Several recommendations have been made for the treatment of displaced transcervical fracture type II (Delbet classification)(1,2,5-8). However there are no...

A fracture is defined as a disruption in the integrity of a living bone, involving injury to the bone marrow, periosteum, and adjacent soft tissues. Many types of fractures exist, such as pathologic, stress, and greenstick fractures. When a fracture occurs, it is described radiographically and clinically in...

This article discusses fractures of the femoral diaphysis. The femur is the largest and strongest bone and has a good blood supply. Because of this and its protective surrounding muscle, the shaft requires a large amount of force to fracture. Once a fracture does...

Hip fractures are classified as intracapsular, which includes femoral head and neck fractures, or extracapsular, which includes trochanteric, intertrochanteric, and subtrochanteric fractures. The location of the fracture and the amount of angulation and comminution play integral roles in the overall morbidity of the patient, as does the preexisting physical condition...

Isolated fracture of the lateral condyle of the femur or Hoffa fracture is a rare lesion and has been reported to occur with supracondylar fracture of the femur, fracture of the femoral shaft and knee dislocation. We report a rare case of ipsilateral Hoffa fracture and patellar dislocation, which has...

Although there is a high rate of bisphosphonate use among patients with atypical femur fractures, the absolute risk for such fractures is small enough to justify prescribing the drugs.
May 9, 2011 — Almost 78% of all Swedish women aged 55 years and older who sustained an atypical femur fracture in...

Late complications of total knee-replacement arthroplasty with a non-hinged prosthesis are known to include loosening on fracture of either component, dislocation, and infection. Supracondylar femoral fracture after knee replacement has not, to our knowledge, been described. We are reporting our experience in the management of four patients with this problem...

A male 41 years old transferred to our unit with 3 week old femoral fracture near the knee prosthesis after a mimimal fall. In 1994 he sustained multiple injury with open patella fracture (complicated with septic arthritis), and ipsilateral femoral shaft fracture treated by ex-fix.
TKA performed in 1998. In 2001...

Arthrofibrosis of the Knee After Tibial Spine Tibial spine fracture is an uncommon injury in children and adolescents. According to Meyer’s classification, nondisplaced or minimally displaced type I and type II fractures can be treated by external splint or long leg cast in extension. Displaced type III or type IV...

The incidence of femur fracture around total hip arthroplasties continues to increase at substantial cost to society. These fractures are frequently associated with a loose femoral component. Consequently, we sought to test whether femoral component loosening predisposes to periprosthetic femoral fracture.
Based on our data, patients with loosened femoral components...

Abstract Aims: To examine the roles of fracture stability, anatomical reduction and screw position on cut through failure of Dynamic Hip Screw (DHS) implants. Methods: This is a retrospective study of consecutive patients treated with a DHS implant following intertrochanteric fractures of the proximal femur. Fracture stability was assessed from fracture...

Interlocking nails are commonly performed using an image intensifier. These are expensive and are not readily available in most resource-poor countries of the world. The aim of this study was to achieve interlocking nailing without the use of an image intensifier. This is a prospective descriptive analysis of 40 consecutive...

Fractures have been treated with immobilization, traction, amputation, and internal fixation throughout history. Immobilization by casting, bracing, or splinting a joint above and below the fracture was used for most long bone fractures, with the exception of the femur, for which traction was the mainstay of treatment. In the past,...

Fracture of the femoral stem is a rare mode of failure for total hip arthroplasty. A 1995 survey study 7 reported 172 stem fractures out of 64,483 cases (including both cemented and cement less prostheses), for an incidence of 0.27%. However with increasing number of hip replacements done these days,...

Results A history suspicious for abuse, physical or radiographic evidence of prior injury, and age younger than 18 months were risk factors for abuse. Patients with no risk factors had a 4% chance, patients with one risk factor had a 29% chance, patients with two risk factors had an 87% chance,...

Polyethylene wear has been recognized in association with many designs of prostheses used in total knee arthropbasty”2’3. Three important factors that affect stresses on the polyethylene include the conformity of the articular surfaces, the thickness of the polyethylene, and the elastic modulus of the polyethylene. Polyethylene wear in a total knee prosthesis is related to small...

Archived 2003. UPMC. The introduction of the intramedullary hip screw (IMHS) was hailed as a solution for the treatment of complex intertrochanteric (IT) and subtrochanteric (ST) femur fractures. In fixation with the IMHS benefits of intramedullary shaft stabilization are combined with the advantages of sliding hip screw fixation. Fixation with...
