The distal femur is the bottom part of your thigh bone. It is a trapezoidal shaped bone that makes up the top of your joint and sits just behind your knee cap. Your knee is the largest weight-bearing joint in the body Distal Femur. Distal femur shows a sarcoma that has developed in a site previously treated with bone cement for conventional GCT of bone. From: Diagnostic Pathology: Bone (Second Edition), 2017. Related terms: Lesion; Tibia; Cartilage; Bone Density; Epiphysis; Femur; Osteosarcoma; Proximal Tibi The distal femur includes both the supracondylar and condylar regions (Fig. 33.1). The supracondylar area of the femur is the zone between the femoral condyles and the junction of the metaphysis with the femoral shaft. This area comprises the distal 10 to 15 cm of the femur
Distal femur fractures are traumatic injuries involving the region extending from the distal metaphyseal-diaphyseal junction to the articular surface of the femoral condyles. Diagnosis is made radiographically with CT studies often required to assess for intra-articular extension INTRODUCTION. Distal femoral fractures comprise approximately 3%-6% of all femoral fractures. 1 The associated mechanism of injury can be of high or low energy; high-energy mechanisms such as motor vehicle accidents are more common in the younger population as compared with low-energy mechanisms such as fall from stand in the elderly and osteoporotic patients. 2 Distal femoral fractures are. A large well defined central medullary focal bony lesion is noted at the distal left femoral shaft, with the following features: it measures 3.1 x 2.7 x 5.2 cm in maximum dimensions it expresses heterogeneous T1 hypo and T2 hyperintense signal with intra-lesional T1 mixed hyper and hypointense and T2 hypointense foc

Introduction. Distal femur fractures are fractures extending from the distal metaphyseal-diaphyseal junction of the femur to the articular surface of the femoral condyles.. They account for around 3-6% of femur fractures.They occur both in younger patients (as the result of high energy trauma) or in older patients (from low energy trauma as a pathological fracture secondary to osteoporosis or. The femur is the thigh bone. Distal femur indicates the part of the thigh bone just above the knee A Fracture of the Distal Femur is a break or crack that occurs anywhere within the lower region of the femur (near the knee
The distal femur is defined as the region from the metaphyseal-diaphyseal junction to the articular surface of the knee, involving approximately the distal 15 cm of the femur. The shaft of the femur is a cylindrical shape and extends into two curved condyles at the distal end Distal femur fractures include fractures of the supracondylar and intercondylar region and are relatively common injuries. The goals of treatment follow AO principles of anatomic reduction of the articular surface, restoration of limb alignment, length, and rotation. Despite improvements in implant design, management of distal femur fractures remains a challenge; fractures are often comminuted.
Distal femur fractures can be classified as metaphyseal fractures or physeal fractures. Metaphyseal fractures — Transverse distal metaphyseal fractures (also called supracondylar femoral fractures) are the most common type of distal femur fracture in infants and young children The distal femur has a unique anatomical shape. Seen from an end-on view, the lateral surface has a 10° inclination from the vertical, while the medial surface has a 20-25° slope. A line is drawn from the anterior aspect of the lateral femoral condyle to the anterior aspect of the medial femoral condyle (patellofemoral inclination) that slopes approximately 10° This case describes a distal femur stress fracture in a long-distance hiker. While 1 case does not prove causality, it suggests there may be a need for a well-designed epide-miologic study identifying occurrence of knee pain in long-distance hikers and distal femur stress as a possible etiology. Clinicians should consider stress fracture on th The DePuy Synthes Vet 4.5 mm LCP Distal Femur Plate is intended for comminuted 1 fractures of the proximal phalanx in horses. 1.Fractures lacking an intact strut of bone extending from the proximal to distal articula
Demonstration of distal femoral resection and GMRS replacement using a lateral approach to the distal thigh The lower extremity of femur (or distal extremity) is the lower end of the femur (thigh bone) in human and other animals, closer to the knee. It is larger than the upper extremity of femur, is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior; it consists of two oblong eminences known as the lateral condyle and medial condyl Distal femoral fractures have been reported to go onto nonunion at a rate of 6‐24%. Distal femur fractures occur in a bimodal distribution in the population, with an increased frequency in young. The epiphysis of the distal femur is the first epiphysis to ossify and is present at birth. From birth to skeletal maturity the distal femoral physis contributes 70% of the growth of the femur and 37% of the growth of the lower extremity. The distal femoral physis has an average growth of 1.0 cm/year, making it the fastest growing physis

The distribution of reaming debris in the knee joint is avoided by opening the joint with the hollow reamer. Sufficiently recessed placement of the implant prevents protruding implant edges. As a result of the ventral and dorsal oblique surfaces of the Targon® RF, the nail recess can be kept.
Surgical Technique - Distal Femur Foreword Distal femoral fractures can lead to complex tissue injuries. Conservative treatment often results in malalignment or non-unions as well as stiffness of the knee. To reduce the occurrence of these problems, open reduction and internal fixation of the bone can be carried out Distal femur Fractures Prepared by : Dr.Loay Aburaiya 2016-2017 2. Outline : - Basic anatomy - Introduction - Type of fractures - Clinical features - Investigations - Treatment - surgical techniques - Complications 3. Basic anatomy of femur - only bone in the thigh. - It is classed as a long bone, and is the longest bone in the body The femur (/ ˈ f iː m ər /, pl. femurs or femora / ˈ f ɛ m ər ə /), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates.The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia (shinbone) and patella (kneecap), forming the knee joint.By most measures the two (left.
In the distal femur, the shape of the patellar surface and symmetry of the femoral condylar widths suggest that the knee was not typically abducted but assumed more variable movements and/or postures The distal femur is an important part of the knee joint because it forms the entire top half of the joint and the grove that the knee cap travels in. The strong ligaments and tendons of the knee attach to the distal femur and allow for knee strength and stability. The distal femur is also covered with a layer of cartilage that allows the knee. 17.

The Synthes LCP Distal Femur Plates are intended for buttressing multifragmentary distal femur fractures including: supracondylar, intra-articular and extra-articular condylar, periprosthetic fractures; fractures in normal or osteopenic bone; nonunions and malunions; and osteotomies of the femur. 094218-18062 A large bilobed exostosis arises from the posteromedial aspect of the distal femoral diaphysis, extending into the metaphyseal region. The medullary cavity of the exostosis is directly continuous with that of the femur and although the cortex is thinned in several areas, it remains intact According to Sabatini, There is the risk of recurrence or malalignment following distal femoral osteotomy in pediatric patients. Therefore, patients should be followed through skeletal maturity. The distal end of the femur has a saddle that rests on the top of the tibia. It has rounded edges on either side of the knee joint, known as the condyles. The depression between the condyles is called the patellar groove. Inside the body of the femur is the medullary cavity, which contains bone marrow. At the ends of the femur are areas of.
A distal femoral osteotomy (knock knee surgery) is a procedure whereby a surgical fracture is created at the end of the femur and the shape of the bone is changed. In general, these are performed for patients with knock knees, which we call valgus alignment, and the goal of the surgery is to realign them such that the weightbearing axis is. Minimally invasive plate fixation for distal femur fractures after TKA showed good results. Minimally invasive plate osteosynthesis is a recommendable treatment method for periprosthetic fractures

Introduction Distal femoral replacement (DFR) and open reduction and internal fixation (ORIF) are surgical options for comminuted distal femur fractures. Comparative outcomes of these techniques are limited. The aims of this study were to compare implant survivorship, perioperative factors, and clinical outcomes of DFR vs. ORIF for comminuted distal femur fractures. Methods Ten patients.
the distal femur. In more complex fractures, CT is used to delineate intra-articular extension, degree of comminution, and fracture lines in the coronal plane. A recent study re-ported coronal plane fracture in 38.1% of all distal femoral fractures, with the lateral condyle most fre-quently involved.5 In that study, plain radiography missed 31% o Femur Shaft Fractures (Broken Thighbone) Your thighbone (femur) is the longest and strongest bone in your body. Because the femur is so strong, it usually takes a lot of force to break it. Motor vehicle collisions, for example, are the number one cause of femur fractures. The long, straight part of the femur is called the femoral shaft The Zimmer Periarticular Distal Femoral Locking Plate is designed to be placed slightly anteriorly on the distal femoral condyles. In order to achieve an accurate lateral x-ray or c-arm image, it will be necessary to externally rotate the affected limb 20-30˚. As in distal targeting of intramedullary nails, visualization of round holes.
The distal femoral cut is made after clinically assessing the depth. It has the additional option of +/−2, +/−4 mm or +/−6 mm cut for increasing or decreasing the depth of the distal femur resection. In the second embodiment of the jig, besides the first steps detailed above, the placement of the subsequent jig is marked directly through. The TomoFix Medial Distal Femur Plate is designed according to the locking compression plate (LCP) principles. The distal plate head features four threaded locking holes that were designed to adapt to the anatomy of supracondylar femur. The proximal plate shaft features Combi holes that accept both cortex and locking screws A distal femoral cortical irregularity at the attachment sites of tendons was a frequent incidental finding on knee MRI scans, with an increased prevalence in youth competitive alpine skiers; this finding should not be mistaken for malignancy Distal femoral resection at knee replacement - The effect of varying entry point and rotation on prosthesis position. Distal femoral cut perpendicular to mechanical axis may induce varus instability in flexion in medial osteoarthritic knees with varus deformity in total knee replacement: a pitfall of the navigation system
Distal femur fractures are rare injuries with a bimodal distribution (high-energy injury in young males and low-energy fragility fractures in old females). Their management can be challenging: open reduction and internal fixation (ORIF) with distal femur locking plates is a commonly performed procedure especially in comminuted fractures with articular involvement. Anxiety regarding the. Distal femur fractures in younger age groups are associated with high-impact injury leading to severe comminution and soft tissue injuries. Most of the intra-articular distal femur fractures occur as a result of axial loading accompanied by a variable amount of flexion. An 18-year-old male patient who had met with a road traffic accident was brought to the trauma center Intramedullary nailing is one of the most convenient biological options for treating distal femoral fractures. Because the distal medulla of the femur is wider than the middle diaphysis and intramedullary nails cannot completely fill the intramedullary canal, intramedullary nailing of distal femoral fractures can be difficult when trying to obtain adequate reduction Distal femoral varus osteotomy may be used to treat valgus knee malalignment or to protect a knee compartment in which cartilage restoration surgery (such as osteochondral or meniscus allografting) has been performed. Medial closing-wedge osteotomy has demonstrated good success in treatment of osteoarthritis in published series, but few studies.

Distal Fem & Prox Tib Microfracture App by J. Baumfeld, MD, M. Lemos, MD 2_2014 Compiled by K. DelPaine, PT Review date 3_16 2 Overview In the knee the articular cartilage at the femoral condyles, tibial plateau and patella can be damaged or torn during athletic trauma or injury causing an articular cartilage lesion Distal femur fractures have been treated by open reduction and internal fixation (ORIF) using locking compression plates (LCPs), dynamic condylar screws (DCSs), angled blade plates (ABPs) and intramedullary nails (IMNs). Locking plates have gained favor because they are less invasive,. Distal femoral fractures (at the bottom end of the femur) present a different type of problem. The bone is much wider at the distal end and more difficult to stabilize. Everything is even more challenging when the fracture is comminuted (broken into many little pieces) Distal two-thirds of distal femur, including knee joints, is shown. Knee joint space will not appear fully open because of divergent x-ray beam. Position: No rotation is evidenced; femoral and tibial condyles should appear symmetric in size and shape with the outline of patella slightly toward medial side of femur Short metaphyseal segments remaining after distal femoral tumor resection pose a unique challenge. Limb sparing options include a short stemmed modular prosthesis, total endoprosthetic replacement, cross-pin fixation to a custom implant, and allograft prosthetic composite reconstruction (APC). A series of patients with APC reconstruction were evaluated to determine functional and radiologic.
Advice and exercises after distal femoral replacement, November 2020 1 . Advice and exercises after distal femoral replacement . Introduction . A distal femoral replacement is done for tumour removal, revision of total knee replacements and complex fractures. The aim of the surgery is to relieve pain and to increase function Distal Femur Locking Plate provides an excellent fit against the surface of the bone. Condylar scallops on the distal end of the plate allow easy placement of lag screws outside the plate for fixation of articular fractures. Each screw hole will accept one of four different screws allowing you to customize the scre The full length xray helps in identifying the individual bone segment deformity e.g the xray picture on the right side shows a valgus in the distal femur (the outer angle of the thigh bone close to the knee is smaller than the normal range). The green lines mark the joint lines of the hip & knee
In certain types of femur fractures (displaced fractures), the trauma knocks the broken thigh bone pieces out of alignment. Femur fractures that occur near the knee (distal femur) are known as distal femoral fractures. Open reduction and internal fixation (ORIF) is a common surgery to fasten the broken femur together with hardware that allows it to heal correctly Total femoral replacement.

Beware knee stiffness, try not use for longer than 2 to 3 weeks. Remember the lateral knee joint capsule reaches 1.25-2cm above knee joint, dont forget the distal femoral physis in children. In general, the pin should pass along or slightly posterior to the midcoronal plane of the femoral shaft The post-operative weight bearing recommendations for distal femur fractures treated with locking plate vary widely which motivated Granata et al. to evaluate the biomechanics of immediate weight bearing of distal femur fractures treated with locked plate fixation. They found that the fatigue limit of the locked plate constructs was 1.9 times.
A femur fracture is a break in the femur. The distal femur is the lower part of the thigh bone which flares out like an upside-down funnel and its lower end is covered by a smooth, slippery articular cartilage that protects and cushions the bone during movement The distal femur is a far more frequently affected site compared to the diaphyseal femur: 44% and 3%, respectively . In terms of size, the lesion in the distal femur of our patient had progressed much more than the lesions in the fracture fragments (Figure 5B) A review of available radiographic and pathologic material revealed evidence that two distinct anatomical variations may be found on the posteromedial aspect of the distal femur. One, the femoral c.. A femoral fracture is a fracture of the femur (thigh bone). A femoral shaft fracture is defined as a fracture of the diaphysis occurring between 5 cm distal to the lesser trochanter and 5 cm proximal to the adductor tubercle occurs by chronic, repetitive activity that is common to runners and military Background Open reduction and internal fixation (ORIF) is a commonly used treatment for fractures throughout the body, including the distal femur. Supracondylar fractures of the femur account for approximately 7% of all femur fractures
DISTAL FEMUR FRACTURES. Distal femoral physeal fractures in children may be difficult to treat and are associated with a high rate of complications including growth arrest. 1 Close follow-up is necessary to detect early angular deformity that may result from a partial growth arrest. The greater the severity of fracture and displacement across the physis, the higher the risk of growth arrest. 2. The concept of measured resection was introduced by Hungerford, Kenna, and Krackow in 1978 and is currently incorporated to some degree in most instrument systems. The concept involves resecting that amount of the distal and posterior femur that will be replaced by the prosthetic components The POLYAX™ Locked Plating System is indicated for the treatment of distal femur and proximal tibia fractures. The system is intended for use in open or percutaneous fracture fixation cases requiring Open Reduction Internal Fixation (ORIF) of closed and open fractures of the distal femur and proximal tibia, including repair of non The fracture of the distal extremity of the femur continues to represent a fracture that is difficult to resolve because of its location and anatomy, which adds to the importance of the associated joint (the knee). This work was responsible for collecting and selectin
mechanism that allows the four distal screws (2- transverse and 2-oblique) to be mechanically locked to provide enhanced distal femoral fixation. This universal retrograde femoral nail is composed of titanium alloy that incorporates a 1.8m radius of curvature and a 5° distal bend, that is initiated at 45mm from the driving end Six of 7 studies reported that the MPFL origin on the distal femur lies distal to the medial distal femoral physis in the majority of specimens. The MPFL originated distal to the medial distal femoral physis in 92.8% of participants at a mean distance of 6.9 ± 2.4 mm
of the distal femur is the TEA distal femur of 76.34 ± 5.89 mm, while the smallest average is CAP of 23.33 ± 3.19 mm. The method used for measuring the parameters of the tibia proximal bone is the same as the measurement of the distal femur bone, as well as the measurement of one limb and sample used The femur is a very large, strong bone that is difficult to break. A broken femur is usually caused by a severe accident; vehicle accidents are one of the primary causes The indications and contraindications for distal femoral osteotomy are similar to those for high tibial osteotomy. Surgical Technique A lateral approach is used to perform a distal femoral osteotomy. The iliotibial band is split along its fibers and the vastus lateralis is elevated off the femur to expose the femoral shaft and metaphysis. A. Objective: To determine the functional and radiological outcome of fracture distal femur treated with retrograde interlocking nail.Methods: This was a descriptive study conducted at Department of Orthopaedics surgery Jinnah Post Graduate Medical Centre(JPMC) from 15th February 2016 to 10th January 2019.All patients fulfilling the inclusion criteria were treated with retrograde nailing Treatment of distal femoral fractures with lateral locking plate causes less damage to the soft tissue and blood supply of the medial side of distal femur, reducing the risk of intraoperative. Distal femoral fracture with excision and TKR The example cited, says the patient also had severe degenerative arthritis of the knee, along with the acute distal femoral fracture. The severe arthritis alone, even without the fracture, should support this procedure. But, this was no ordinary TKR
