The longest and largest bone of the skeleton, it is situated between the hip and the knee.
The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.
Congenital dislocation of the hip generally includes subluxation of the femoral head, acetabular dysplasia, and complete dislocation of the femoral head from the true acetabulum. This condition occurs in approximately 1 in 1000 live births and is more common in females than in males.

A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)
A form of muscle hypertonia associated with upper MOTOR NEURON DISEASE. Resistance to passive stretch of a spastic muscle results in minimal initial resistance (a "free interval") followed by an incremental increase in muscle tone. Tone increases in proportion to the velocity of stretch. Spasticity is usually accompanied by HYPERREFLEXIA and variable degrees of MUSCLE WEAKNESS.

Is there any relationship between Q-angle and lower extremity malalignment? (6/8)

OBJECTIVE: The aim of this study was to assess the relationship between Q-angle and lower extremity alignment in women with unilateral patellofemoral pain syndrome (PFPS). METHODS: Eighty-five women with unilateral patellofemoral pain participated in the study, with each subject acting as their own internal control using the unaffected limb. Lower extremity alignment and Q-angles of the affected and unaffected knees were compared. RESULTS: There was a significant difference in the Q-angle between the affected (19.61+/-4.35) and the unaffected (17.63+/-4.29) side (p=0.00). There was also a significant difference in the lateral distal femoral angle (LDFA) (81.00+/-2.58 vs. 81.83+/-3.03; p=0.03) and no significant difference in the medial proximal tibial angle (MPTA) (87.88+/-2.63 vs. 87.60+/-3.29; p=0.51) between the affected and the unaffected side. There was no relationship between the Q-angle and LDFA (r=0.001, p=0.99), and MPTA (r=-0.051, p=0.64) in the affected side of the patients. There was also no relationship between the Q-angle and LDFA (r=0.179, p=0.64), and MPTA (r=-0.146, p=0.18) in the unaffected side of the patients. CONCLUSION: Increased Q-angle and decreased LDFA may be associated with PFPS although cause or effect cannot be established. There was no relationship between the Q-angle and lower extremity malalignment. Large prospective longitudinal studies are needed to detect changes in the femoral anteversion and toe-in gait and to establish if these features are a cause of PFPS.  (+info)

Using the transverse acetabular ligament as a landmark for acetabular anteversion: an intra-operative measurement. (8/8)

PURPOSE. To measure the transverse acetabular ligament (TAL) anteversion in hips with severe deformity, using fluoroscopy-computed tomographic navigation. METHODS. 31 hips in 10 men and 19 women aged 40 to 78 (mean, 58.7) years who underwent total hip arthroplasty for primary osteoarthritis (n=6) or osteoarthritis secondary to developmental hip dysplasia (n=19) or congenital hip dislocation (n=6) were included. The severity of hip dislocation was classified according to the Crowe classification; 15 hips were grade 1, 7 were grade 2, 3 were grade 3, and 6 were grade 4. The TAL anteversion was measured using fluoroscopy-computed tomographic navigation. The difference in TAL anteversion between non-dislocated hips (Crowe grade 1, n=15) and dislocated hips (Crowe grades 2-4, n=16) was compared. RESULTS. In all 31 hips, the TAL could be visualised intra-operatively. No patient reported severe pain, early wear, loosening, or dislocation after 2 years. The mean TAL anteversion and inclination angles measured by the navigation system were 26.5 (SD, 8.9; range, 8-42) degrees and 41.5 (SD, 4.6; range, 32-49) degrees, respectively. 22 of the 31 hips were in the safe zone. TAL anteversion in non-dislocated and dislocated hips was not significantly different. Inter- and intra-observer mean absolute differences in TAL anteversion were 0.3 and 0.4 degree, respectively. CONCLUSION. The TAL is a useful anatomic landmark for total hip arthroplasty in dislocated hips.  (+info)

Open surgical fixation was performed on four hip joints in three dogs who were suffering from caudoventral hip luxations for which closed reduction had previously failed. Stabilization of the joint was achieved with a ventral coxofemoral approach, which augmented the function of the transverse acetabular ligament using a sling implant through a bone tunnel (n = 1), a sling implant around two pelvic screws (n = 1), or an internal fixator plate (n = 2). Transverse acetabular ligament augmentation resulted in successful joint stabilization in all cases, and should be considered for the surgical reduction of caudoventral hip luxations in dogs. The use of an internal fixator plate, while preserving soft-tissue blood supply and resulting in minimal to no long-term arthritic changes, may provide an optimal outcome. ...

Hip contact stress is considered to be an important biomechanical factor related to development of coxarthrosis. The effect of the lateral coverage of the acetabulum on the hip contact stress has been demonstrated in several studies of hip dysplasia, whereas the effect of the anterior anteversion remains unclear. Therefore, the joint hip contact stress during normal level walking and staircase walking, in normal and dysplastic hips, for small and large acetabular anteversion angle was computed. For small acetabular anteversion angle, the hip contact stress is slightly increased (less than 15%) in staircase walking when compared with normal walking. In hips with large angle of acetabular anteversion, walking downstairs significantly increases the maximal peak contact stress (70% in normal hips and 115% in dysplastic hips) whereas walking upstairs decreases the peak contact stress (4% in normal hips and 34% in dysplastic hips) in comparison to normal walking. Based on the presented results, we ...
This is a fibrous continuation of the acetabular labrum that is completely collagenous and contains no chondrocytes or cartilage. It crosses the acetabular notch and binds the ends of the cartilaginous labrum. As it crosses the notch it leaves a small gap between it and the rim of the acetabulum that allows vessels to access the joint ...

AU - Reinert, Charles M.. PY - 2014/2/1. Y1 - 2014/2/1. N2 - Rotational malalignment after intramedullary (IM) nailing of femoral fractures remains a significant problem. A technique using intraoperative fluoroscopy and the anteversion inherent to the IM nail for obtaining appropriate femoral rotational alignment is presented. The technique is advocated as a simple alternative to more complex methods for estimation of femoral anteversion during placement of femoral IM nails. This method is simple and requires intraoperative fluoroscopy on the injured extremity alone. It reliably sets the femoral anteversion within a normal physiologic range with minimal additional intraoperative steps and without preoperative measurements..

AU - DAntonio, James A.. PY - 2001/1/1. Y1 - 2001/1/1. N2 - Morphologic features of the hips, in particular those features germane to determination of acetabular and femoral anteversion angles and femoral head offset, were studied in 50 male and 50 female human skeletons with bilateral normal joints. Four distinct configurations were identified relative to the anterior acetabular ridge. The majority (121, 60.5%) were curved; 51 (25.5%) were angular; 19 (9.5%) were irregular; and nine (4.5%) were straight. The acetabular anteversion angle measured 19.9° ± 6.6° (range, 7°-42°) and was significantly larger in females (21.3° ± 7.1°) versus males (18.5° ± 5.8°). The notch acetabular angle, which can be identified easily intraoperatively, was defined as the angle created at the intersection of a line from ...
We previously described that the anteroposterior (AP) axis of the tibia is approximately perpendicular to the transverse axis of the anterior pelvic plane (APP) in the standing position in healthy subjects. The purpose of this study was to investigate the rotational alignment between the APP and clinical epicondylar axis and the AP axis of the tibia relative to pelvic coordination in the standing position in normal subjects and in women with developmental dysplasia of the hip (DDH) to aid decision making for surgeons in the alignment of implants in total hip or knee arthroplasty. This study included 77 Japanese women. Twenty-nine in the DDH group underwent curved periacetabular osteotomy; 48 women without lumbago and knee pain were included in the normal group. Femoral neck anteversion (FNA), condylar twist angle, and knee rotation angle were measured in femoral coordination. The angle between the femoral neck axis and clinical epicondylar axis (CEA) was measured, the transverse axis of the APP was also

Pigeon toes, an in-toeing gait, femoral anteversion and tibial torsion are different types of atypical torsional alignment of the thighs, knees and feet that occur in children, and are linked to bone growth as well as the strength, flexibility and coordination of the leg and foot muscles.
Treatment will depend on your childs symptoms, age, and general health. It will also depend on how severe the condition is.. The twisting in of the thighbone usually gets better with time. Many cases correct themselves as the child grows. Your child will likely walk normally by 8 to 10 years of age.. Your childs healthcare provider may prescribe braces or special shoes. But most studies have found that these treatments dont help. If the femoral anteversion is severe, your child may need surgery to straighten the thighbone.. It is important to know that femoral anteversion usually does not lead to arthritis or any other future health problems.. ...

Due to it being tangential to the distal femoral axis, the anteromedial portal presents significant risk of causing iatrogenic damage, and of producing tunnels that are too short for optimal osseointegration. Flexible reamers were developed to eliminate the need for knee hyperflexion and offer better-controlled orientation of the femoral tunnel. We aimed to compare the anteversion and length of femoral tunnels drilled using flexible reamers to those drilled using rigid reamers. Between May 2012 and December 2013, all patients receiving ACL reconstruction performed by one surgeon were operated on using either a rigid or a flexible reamer from the same supplier (Versi-Tomic® system, Stryker, Kalamazoo, Michigan). The height of each patient was recorded, and the length and anteversion of the femoral tunnels were measured intra-operatively and on true lateral radiographs, respectively. Thirty-seven patients underwent operations using the rigid instrumentation, and 43 using the flexible instrumentation.
The size and shape of the acetabulum and of the femoral head influence the injury tolerance of the hip joint. The aim of this study is to quantify changes in acetabular cup geometry that occur with age, gender, height, and weight. Anonymized computed tomography (CT) scans of 1,150 individuals 16+ years of age, both with and without hip trauma, were used to describe the acetabular rim with 100 equally spaced points. Bilateral measurements were taken on uninjured patients, while only the uninjured side was valuated in those with hip trauma. Multinomial logistic regression found that after controlling for age, height, weight, and gender, each 1 degree decrease in acetabular anteversion angle (AAA) corresponded to an 8 percent increase in fracture likelihood (p≺0.001). Age, weight, and gender were found to influence anteversion angle significantly, with each 10 years in age increasing AAA by 1.07 degrees, each 10 kg of weight decreasing AAA by 0.45 degrees, and being female resulting in 1.42 ...

An alignment system for aligning an acetabular cup insertion instrument utilizes pre-operative preferably standing x-rays and intra-operative x-rays to allow the surgeon to compensate for the position of a patient on an operating room table. The system uses a programmable computer connected to a digital x-ray system and an navigation tracking system to provide input for calculating the inclination and anteversion angles of an acetabular cup impactor based on a pre-operative plan developed from the standing x-rays. The system calculates changes in lengths and angles between anatomic landmarks on the pelvis to alter the intra-operative orientation of the acetabular reaming and impacting instruments to produce the desired inclination and anteversion angles when the pelvis is reoriented as the patient is placed on an operating table.
The four limb buds begin to develop in the fifth week of gestation with all four having a parallel axis. The great toes initially develop in a preaxial position, and with medial rotation are seated at the midline by week seven. Intrauterine molding continues, with variable positioning of the feet, internal rotation of the tibia, and external rotation of the hip. This can lead newborns to have common deformities related to these positions. The lower extremities continue to externally rotate in the postnatal period until around age 8-10 years when adult values are typically reached. On average, femoral anteversion will decrease about 25 degrees to a value of 15 degrees, with the tibia externally rotating 15 degrees (Staheli, 1985 ...

Having been told through the years that I have tibial torsion in my left leg, I am not always in agreement with the doctors and therapists. Yes, there is something there and has been since I started running in high school that goes along with my femoral anteversion in that leg, but sometimes it is bit very pronounced and sometimes it looks horrible. Some of the photos of my leg twisting and compensating in the last 10-15 years of running I did where just crazy looking. Since my arthroscopic surgery in 2011, my running has been curtailed, but one thing that I notice is that some days I feel great (and that is when my lower leg is straightest) and other days I feel terrible and that is when my leg is rotated out a whole lot more and my knee gets really tight ...
Unlike other surgical navigation systems the NaviPro system is Image Free. No CT, MRI or fluoroscopic imaging is needed. All data is acquired by simple and quick intraoperative registration techniques. Trackers are attached to the pelvis and proximal femur* prior to dislocating the hip. They are then utilized throughout the case to monitor the relative position of the femur and pelvis in order to provide you with accurate feedback on leg length and offset changes.. A unique table positioner* orients the patient and provides touch points that allow accurate definition of the anterior pelvic plane. This pelvic plane becomes the reference for true anatomic cup anteversion and abduction positioning.. A short series of descriptive screen images walk the user through the simple steps required to navigate the hip. A printout of the relevant results is available at the end of the surgical case for inclusion with the patient chart ...

The angle formed between the longitudinal axis of the femur, representing the pull of the quadriceps muscle, and a line that represents the pull of the patellar tendon. A clinical measure of the angle is obtained by connecting the central point of the patella with a line through the anterior iliac spine above and with a line through the tibial tuberosity below. The Q-angle is normally less than 15° in men and 20° in women when the quadriceps are relaxed. The angle becomes smaller when the quadriceps are contracted. A Q-angle greater than 20° increases the likelihood of the quadriceps pulling the kneecap laterally, increasing the risk of knee disorders such as patellofemoral pain syndrome.. Q-angle ...
This pictorial review aims to provide the radiologist with simple and systematic guidelines for the radiographic evaluation of a hip prosthesis. Currently, there is a plethora of commercially available arthroplasties, making postoperative analysis not always straightforward. Knowledge of the different types of hip arthroplasty and fixating techniques is a prerequisite for correct imaging interpretation. After identification of the type of arthroplasty, meticulous and systematic analysis of the following parameters on an anteroposterior standing pelvic radiograph should be undertaken: leg length, vertical and horizontal centre of rotation, lateral acetabular inclination, and femoral stem positioning. Additional orthogonal views may be useful to evaluate acetabular anteversion. Complications can be classified in three major groups: periprosthetic lucencies, sclerosis or bone proliferation, and component failure or fracture. Teaching Points • To give an overview of the

Tibial torsion, the most common cause of in-toeing, occurs when the lower leg bone (tibia) tilts inward. If the tibia tilts outward, a child will toe-out. When the thighbone, or femur, is tilted, the tibia will also turn and give the appearance of in-toeing or out-toeing. The medical term for this is femoral anteversion. In-toeing can also be caused by metatarsus adductus, a curvature of the foot that causes toes to point inward ...

When implanting the cup (or acetabular component), most surgeons attempt to implant it into a specific position. This positioning is based on each surgeons specific surgical approach, technique, prosthesis used and experience. Dr. George Lewinnek, an orthopedic surgeon in Worcester, Mass., published a study and popularized the concept of a safe zone for cup positioning. Based on his own specific surgical goal, he found that if the cups were placed within a range of 10 degrees plus or minus his goal, then the rate of dislocation was significantly less (1.5% dislocation) compared to those cups that were outside of the desired range (6.2% dislocation).. Another important study, which recently was published and won the coveted Charnley Award for 2010, describes risk factors associated with cup mal-positioning (poor cup position). It reports on the experience of seven surgeons at Massachusetts General Hospital in Boston. Cup position was analyzed on the postoperative X-rays of 2,061 patients who ...
