INTRODUCTION: Sciatic nerve injury (SNI) is a potentially devastating complication after total hip arthroplasty (THA). Intraoperative neural monitoring has been found in several studies to be useful in preventing SNI, but can be difficult to implement. In this study, we examine the results of using a handheld nerve stimulator for intraoperative sciatic nerve (SN) monitoring during complex THA requiring limb lengthening and/or significant manipulation of the SN. METHODS: A consecutive series of 11 cases (9 patients, 11 hips) with either severe developmental dysplasia of the hip (Crowe 3-4) or other underlying conditions requiring complex hip reconstruction involving significant leg lengthening and/or nerve manipulation...

INTRODUCTION: Orthopedic walking boots have been widely used in place of traditional fiberglass casts for a variety of orthopedic injuries and post-surgical interventions. These walking boots create a leg length discrepancy (LLD). LLD has been shown to alter the kinematics and kinetics of gait and are associated with lumbar and lower limb conditions such as: foot over pronation, low back pain, scoliosis, and osteoarthritis of the hip and knee joints. Past gait analyses research with orthopedic boots is limited to findings on the ipsilateral limb...

INTRODUCTION: Skeletal muscles absorb and transfer kinetic energy during landing and jumping, which are common requirements of various forms of physical activity. Chronic ankle instability (CAI) is associated with impaired neuromuscular control and dynamic stability of the lower extremity. Little is known regarding an intra-limb, lower-extremity joint coordination of kinetics during landing and jumping for CAI patients. We investigated the effect of CAI on lower-extremity joint stiffness, and kinetic and energetic patterns across the ground contact phase of landing and jumping...

It is unclear whether the modern ballet body stereotype of long limbs is advantageous in dance performance. Therefore, we investigated the relationship between leg-length and selected dance movements representative of power, dexterity, and range of motion in ballet dancers at different competence levels. METHODS: The total of 10 recreational, 24 vocational, and 10 professional ballerinas volunteered. They were subjected to: a) lower limb-length measurements, b) power tests (vertical jump-sautés and unilateral countermovement jump-temps levé), c) dexterity tests (tendus and double battement frappes), and d) flexibility tests (lateral active and passive-développé à la seconde)...

Joint immobilization has been demonstrated to modify neural excitability in subsets of healthy populations, leading to disinhibition of cortical and reflexive pathways. However, these findings may have limited clinical application as most models have investigated casting and rigid immobilization, while many musculoskeletal injuries often utilize dynamic immobilization devices such as boot immobilizers and pneumatic splints that allow for modified ambulation. We therefore aimed to determine the short-term effects of ambulation in ankle immobilization devices on nervous system excitability and stiffness in able-bodied individuals...

OBJECTIVE: To investigate changes in body ownership and chronic neuropathic pain in patients with spinal cord injury (SCI) using multisensory own body illusions and virtual reality (VR). METHODS: Twenty patients with SCI with paraplegia and 20 healthy control participants (HC) participated in 2 factorial, randomized, repeated-measures design studies. In the virtual leg illusion (VLI), we applied asynchronous or synchronous visuotactile stimulation to the participant's back (either immediately above the lesion level or at the shoulder) and to the virtual legs as seen on a VR head-mounted display...

The peroneus brevis flap was first described as proximally based by Mathes et al (Surg Clin North Am. 1974;54:1337-1354) and later by Jackson and Scheker (Injury. 1982;13:324-330). A distally based version of this flap by Mathes and Nahai (Reconstructive Surgery: Principles, Anatomy and Technique. 1997:1437e46) was subsequently described in 1997. The first case series of distally based flaps was published by Eren et al (Plast Reconstr Surg. 2001;107:1443-1448).In our experience, the distally based flap is a useful muscle flap to reconstruct small defects in the lateral distal third of the leg...

This article reported the ultilization of cross-bridge flap transplantation and combined free-tissue flap transplantation to treat a 54-year-old male with Gustilo type III-C injuries. Thorough debridement, external fixation and vacuum sealing drainage were performed in the fist-stage treatment. After the removal of negative pressure on VSD devices, the joined free-tissue flaps and the cross-bridge flap were performed to repair the extensive soft-tissue defects. One month later the pedicle of cross-bridge flap was divided and the external fixator connecting both the lower legs was removed...

Sloped walking is challenging for individuals with transtibial amputation (TTA) due to the functional loss of the ankle plantarflexors. Prostheses that actively generate ankle power may help to restore this lost function. The purpose of this study was to use musculoskeletal modeling and simulation to quantify the mechanical power delivered to body segments by passive and powered prostheses and the remaining muscles in the amputated and intact legs during sloped walking. We generated walking simulations from experimental kinematic and kinetic data on slopes of 0, ±3 deg and ±6 deg in eight people with a TTA using powered and passive prostheses and eight nonamputees...

BACKGROUND: Clinical evidence has shown that percutaneous ankle fracture fixation using an intramedullary fibular nail results in good outcomes at 1 year and reduces postoperative wound complications in patients with vulnerable soft tissues. Confirmatory biomechanical evidence of its strength when used to secure a supination external rotation (SER) IV (AO/OTA 44B-type) fracture, compared with traditional plates and screws, is currently lacking. METHODS: Twenty cadaveric lower limbs (10 cadavers) had a SER IV injury surgically created...

Iatrogenic arteriovenous fistula (AVF) is an unusual and potentially fatal complication of lumbar spinal surgery. The presentation of these injuries is usually late, with symptoms such as leg swelling or cardiac failure. It is crucial to suspect AVF in the patient which presents to emergency with lumbar spinal surgery history. The diagnosis is often based on imaging studies such as computed tomography (CT) or magnetic resonance (MR) angiography. Surgery was the first choice of treatment, but with recent advances in stent technology endovascular approach has become widely popular...

EDITORIAL
Timothy E Hewett
Graft failure rates were higher and inferior subjective outcomes were observed after anterior cruciate ligament reconstruction in patients with generalized hypermobility. This is a clear and corroborative finding that is highly consilient with other reports of similar studies from the published literature. However, controversy remains regarding other potentially predictive and confounding variables. For example, age, activity level, sex, and dynamic neuromuscular control were not considered in this interesting, important, and potentially impactful study...
