BACKGROUND: Leg-length inequality results in an altered position of the spine and pelvis. Previous studies on the influence of leg asymmetry on postural control have been inconclusive. The purpose of this paper was to investigate the effect of structural leg-length discrepancy (LLD) on the control of posture. METHODS: We studied 38 individuals (19 patients with structural LLD, 19 healthy subjects). The examination included measurement of the length of the lower limbs and weight distribution as well as a static posturography...

Congenital lower limb shortening is a group of relatively rare, heterogeneous disorders. Proximal focal femoral deficiency (PFFD) and fibular hemimelia (FH) are the most common pathologic entities in this disease spectrum. PFFD is characterized by variable degrees of shortening or absence of the femoral head, with associated dysplasia of the acetabulum and femoral shaft. FH ranges from mild hypoplasia to complete absence of the fibula with variable shortening of the tibia. The development of the lower limb requires complex and precise gene interactions...

We identified the presence of deformities in the affected pelvis of unilateral Crowe type IV DDH patients, and if present, whether the teardrop and ischial lines were parallel with the sacral base line. We also verified whether the sacral base line provided a better pelvic landmark than the teardrop line for determining leg length inequality (LLI). After leveling the pelvis by using a block to lift the short leg, standard anterior-posterior full-length radiography was performed on 10 patients and 10 healthy volunteers as controls...

BACKGROUND: Treatment of femoral bone loss is difficult. Ilizarov described the bone lengthening technique using a circular external fixator, but this technique is uncomfortable on the femur because of the circular fixator. We have therefore opted for use of a monoplane external fixator to treat femoral bone loss with bone lengthening. The objectives of this study were to determine whether (1) bone union can be obtained with a monoplane external fixator; (2) infections can be treated; (3) the lower limb axes and alignment can be controlled; and (4) patient satisfaction is high...

BACKGROUND: Total hip arthroplasty (THA) is one of the most effective treatments for phase III and IV hip arthrosis. Lower limb length balancing is one of the determining factors of a successful surgery, particularly in patients with developmental dysplasia of the hip (DDH). The purpose of this study was to evaluate the postoperative change in intra-pelvic obliquity (intra-PO) angle in the coronal plane and its effects on leg length discrepancy (LLD) within 2 years. METHODS: A total of 78 patients (70 females, 8 males) were enrolled in this study...

BACKGROUND: Symptomatic leg length inequality accounts for 8.7% of total hip replacement related claims made against the UK National Health Service Litigation authority. It has not been established whether symptomatic leg length inequality patients following total hip replacement have abnormal hip kinetics during gait. METHODS: Hip kinetics in 15 unilateral total hip replacement patients with symptomatic leg length inequality during gait was determined through multibody dynamics and compared to 15 native hip healthy controls and 15 'successful' asymptomatic unilateral total hip replacement patients...

This study assessed the factors related to leg length discrepancy after flexible intramedullary nailing in pediatric patients. A retrospective analysis was conducted of 27 patients with flexible intramedullary nail fixation. Twenty-three patients showed lengthening of the injured limb, and 23 showed lengthening of the injured femur or tibia, with 11 patients having a resultant leg length discrepancy greater than 10 mm. Age at the time of injury was the only factor that was significantly related to leg length discrepancy...

We evaluated an operative technique, described by the Exeter Hip Unit, to assist accurate introduction of the femoral component. We assessed whether it led to a reduction in the rate of leg-length discrepancy after total hip arthroplasty (THA). A total of 100 patients undergoing THA were studied retrospectively; 50 were undertaken using the test method and 50 using conventional methods as a control group. The groups were matched with respect to patient demographics and the grade of surgeon. Three observers measured the depth of placement of the femoral component on post-operative radiographs and measured the length of the legs...

INTRODUCTION: The recent evolution of prosthesis technology has enabled the surgeon to replace entire limbs. These special prostheses, or megaprostheses, were developed for the treatment of severe oncological bone loss; however, the indications and applications of these devices have expanded to other orthopaedic and trauma situations. For some years, surgeons have been implanting megaprostheses in non-oncological conditions, such as acute trauma in severe bone loss and poor bone quality; post-traumatic failures, both aseptic and septic (represented by complex non-unions and critical size bone defects); major bone loss in prosthetic revision, both aseptic and septic; periprosthetic fractures with component mobilisation and poor bone stock condition...

UNLABELLED: A delay in the union of bone regenerate in surgical lengthening procedures and the healing index (HI) are major factors in the quality of the results in progressive bone lengthening. Early removal of the external fixator (EF) is associated with a low rate of postoperative complications, including pin track infection, and with better muscle and joint function recovery. Addition of intramedullary wires (IMWs) to the EF led to a 9-49% decrease in the HI depending on the clinical series...

BACKGROUND: Compelled by the psychosocial implications of short stature, patients with short stature are increasingly undergoing distraction osteogenesis for cosmetic limb lengthening. To the degree that this is true, evaluation of the risks and benefits of this treatment are very important, but to date, there are few studies reporting on using distraction osteogenesis for this indication. QUESTIONS/PURPOSES: We reviewed a group of patients undergoing cosmetic lower-extremity lengthening in terms of (1) soft tissue challenges, (2) bone-related complications, and (3) functional and subjective clinical outcomes...

PURPOSE: The growth plate involvement (GPI) index is reportedly a reliable predictor of final radiographic outcome in Legg-Calvé-Perthes disease (LCPD). We determined whether (1) the GPI index was associated with the lateral pillar classification, (2) the GPI index could predict the final radiographic outcome, and (3) the geometry of proximal femur was affected by presence of physeal involvement. METHODS: We reviewed 47 patients with unilateral LCPD who were treated conservatively...

Leg length discrepancy (LLD) is commonly recognised as a complication of total hip arthroplasty. Some patients with only minor LLD complain of major difficulties. The effect of LLD has been described in the dynamic phase, but not static phase. The aim of this project was to investigate the effect of leg length discrepancy on static limb loading (i.e. Standing). A pedobarograph was used to measure the limb loading of 20 normal volunteers whilst changing the height of the other foot thus simulating a LLD. With both feet at the same level, the left limb took 54% of the load...
