View clinical trials related to Limb Length Discrepancy.
Filter by:This retrospective cohort study included 50 consecutive patients who underwent THR. All surgeries were performed by the same orthopedic surgeon, using posterior approach. In all patients, the same technique of intraoperative measurement of the femoral offset and limb length was used, entailed calculation of the distances between reference points on the ischium, greater trochanter, and the screwdriver. Measurements were collected from radiographic imaging data and surgical reports.
Walking boots are a common form of durable medical equipment Orthopaedic surgeons prescribe both post-operatively and in the treatment of lower extremity injuries. Walking boots create a limb length discrepancy (LLD) which effects joint angles and moment arms in the lower extremities and the spine. These altered mechanics lead to reported back, hip, and knee pain in patients who are prescribed walking boots. Current walking boot literature evaluates gait and ground reaction forces (GRF), focusing primarily on the lower extremities, neglecting the remainder of the kinetic chain including the spine. Alternatively, there is a body of literature evaluating the effects of congenital LLD on spine and posture. However, there is paucity in the literature reporting both the effects of a walking boot on the entire kinematic chain and the subsequent effects of a corrective foot lift. The investigators seek to evaluate lower extremity and spinal kinematics using a motion analysis capture system with healthy subjects undergoing walking trials while wearing normal shoes, a walking boot, and a walking boot with contralateral foot lift. The investigators hypothesize a corrective foot lift will decrease the asymmetrical effects of a walking boot, recreating the kinematics of a more normal gait.
Several techniques exist for epiphysiodesis in limb length discrepancy with different results. Most of the time the results are disappointing for this functional surgery. The aim of this study is understanding the reasons of the failures by analyzing the different steps of the medical care. The patients will be distributed in two groups : "fulfilled contract" and "failed contract" The differences between the two groups will be analyzed.
The Ilizarov external fixator is an external skeletal fixator that is used to stabilize or lengthen the limb bones. Bone lengthen bone occurs through mechanical distraction on the long axis of the bone, thus the method of lengthening is called distraction osteogenesis. This method has been shown successful. Unfortunately, it has also been associated with a substantial number of complications. Muscle shortening and persistent weakness are among the most common complications seen in this procedure. Muscle shortening usually occurs in strong muscle groups such as the planter flexor muscles, as a result of strength imbalance between the opposing muscle groups. Shortening may persist for more than a year after the removal of the fixator and may require surgical intervention. Fortunately, muscular shortening can be prevented by splinting and physiotherapy in the form of stretching and strengthening exercise and functional training. The use of different exercises in rehabilitation can help accomplishing different therapeutic goals. Thus, the choice to use one or the other should depend on the desired treatment goals. Weight bearing (CKC) and non weight bearing (OKC) exercise has been incorporated into rehabilitation; however, the effects of these two types of exercises particularly on muscle flexibility and mechanics have never been studied systematically. Therefore, the purpose of this is to compare the effects of OKC and the CKC exercise on muscle strength, architecture and flexibility. General Hypothesis: The use of open kinetic or closed kinetic chain exercises will have no different effects on muscle function or internal organization during tibial distraction osteogenesis by Ilizarov's method Specific hypotheses 1. There will be no difference between the effects of OKC and CKC on muscle flexibility. 2. There will be no difference between the effect of OKC and CKC exercises on muscle strength. 3. There will be no difference between the effect of OKC and CKC on the internal organization of muscle specifically the pennation angle, muscle thickness and fiber length. 4. There will be no difference between the overall of OKC and CKC exercise on the functional performance of patients.
The purpose of this study is to obtain post market performance and safety data of the Ellipse PRECICE Intramedullary Limb Lengthening System for subjects undergoing unilateral limb lengthening.
