Following median and ulnar nerves, peroneal nerve entrapment is the most frequent nerve involvement in the body Katirji and Wilbourn (1998) [1]. Osteochondromas are the most common benign bone tumors comprising 9% of all bone tumors and 35% of benign bone tumors Porter (2000) [2]. Hereditary exostoses (HME) is an autosomal dominant disorder with variable penetrance characterized by multiple osteochondromas near joints. It is one of the most commonskeletal dysplasias with a frequency of about 1.18%. In this study, we aimed to present a case with a drop foot resulting from osteochondromas of proximal tibia and fibula and help to guide the clinicians in differential diagnosis according to SCARE criteria Agha (2016) [3]...

INTRODUCTION: Neurological complications due to spinal anesthesia are dysesthesia, paresthesia, cauda equina syndrome, and neuropathic joint. However, neurological complications are rare. We report a case of neuropathic joint of knee as a complication of syrinx following postspinal anesthesia. CASE REPORT: A 33-year-old female came with complaints of pain and instability of her left knee and left foot drop. She had developed weakness of her left lower limb following her cesarean section surgery done under spinal anesthesia...

: 102 Background: Intrathecal pumps (ITP) are used to manage severe malignancy related pain by delivering analgesics directly into the cerebrospinal fluid, in theory allowing for a reduced opioid dose and fewer complications. Although there is literature to support efficacy in patients with cancer, including improved survival, this mode of drug delivery also carries a risk of serious complications. Reports of complications in non-malignant pain suggest the risks and mortality related to ITP may be under-appreciated and that injury and liability occur with both ITP placement and ITP maintenance...

AIMS: Due to the complex anatomy of the pelvis, limb-sparing resections of pelvic tumours achieving adequate surgical margins, can often be difficult. The advent of computer navigation has improved the precision of resection of these lesions, though there is little evidence comparing resection with or without the assistance of navigation. Our aim was to evaluate the efficacy of navigation-assisted surgery for the resection of pelvic bone tumours involving the posterior ilium and sacrum...

BACKGROUND: An active ankle dorsiflexion is essential for a proper gait pattern. If there is a failure of the foot lifting, considerable impairments occur. The therapeutic effect of an implantable peroneus nerve stimulator (iPNS) for the ankle dorsiflexion is already approved by recent studies. However, possible affection for knee and hip motion after implantation of an iPNS is not well described. OBJECTIVE: The objective of this retrospective study was to examine with a patient cohort whether the use of iPNS induces a lower-extremity flexion withdrawal response in the form of an increased knee and hip flexion during swing phase...

Pelvic reconstruction after sacral resection is challenging in terms of anatomical complexity, excessive loadbearing, and wide defects. Nevertheless, the technological development of 3D-printed implants enables us to overcome these difficulties. Here, we present a case of sacral osteosarcoma surgically treated with hemisacrectomy and sacral reconstruction using a 3D-printed implant. The implant was printed as a customized titanium prosthesis from a 3D real-sized reconstruction of a patient's CT images. It consisted mostly of a porous mesh and incorporated a dense strut...

Impact is an important aspect of the kicking skill. This study examined foot and ball motion during impact and compared distance and accuracy punt kicks. Two-dimensional high-speed video (4000 Hz) captured data of the shank, foot and ball through impact of 11 elite performers kicking for maximal distance and towards a target 20 m in distance. Four phases were identified during impact, with an overall reduction in foot velocity of 5.0 m · s(-1) (± 1.1 m · s(-1)) and increase in ball velocity of 22.7 m · s(-1) (± 2...

BACKGROUND: Lumbar facet cysts are a benign, degenerative, and fairly uncommon cause for lumbar radiculopathy. The standard surgical treatment for lumbar facet cysts often requires a laminectomy and medial facetectomy which can further destabilize a pathological motion segment. The authors present here a novel technique for transpedicular endoscopic access to the pathology that obviates the need to violate the lamina or facet. METHODS: Two patient cases are described where the lumbar 4-5 facet cysts arise medial to the pedicle...

Imbalance of corticomotor excitability between the paretic and nonparetic limbs has been associated with the extent of upper extremity motor recovery post-stroke, is greatly influenced by specific testing conditions such as the presence or absence of volitional muscle activation, and may vary across muscle groups. However, despite its clinical importance, post-stroke corticomotor drive to lower extremity muscles has not been thoroughly investigated. Additionally, while conventional gait rehabilitation strategies for stroke survivors focus on paretic limb foot drop and dorsiflexion impairments, most contemporary literature has indicated that paretic limb propulsion and plantarflexion impairments are the most significant limiters to post-stroke walking function...

This is the case of an 84-year-old patient 18 years after total knee replacement. Regular follow-up examinations did not take place beyond 10 years of implantation, so that subsequent wear of the polyethylene insert was not detected. The patient presented because of knee pain, swelling of the calf, and a drop foot. Examination showed a large ganglion with pressure on the peroneal nerve, and a loose knee replacement with severe inlay wear and extensive osteolysis around the tibial and femoral implants. This rare case demonstrates the importance of regular clinical and radiological follow-up examinations after total joint replacements, particularly in the long term...

Mild traumatic brain injury typically involves temporary impairment of neurological function. Previous studies used water pressure or rotational injury for designing the device to make a rat a mild traumatic brain injury model. The objective of this study was to make a simple model of causing mild traumatic brain injury in rats. The device consisted of a free-fall impactor that was targeted onto the rat skull. The weight (175 g) was freely dropped 30 cm to rat's skull bregma. We installed a safety device made of acrylic panel...

BACKGROUND: Drop foot is a complex syndrome, with multiple interactions between joints and muscles. Abnormalities in movement patterns can be measured using motion capture techniques, but identifying compensation mechanisms remains challenging. METHODS: In order to identify compensatory mechanisms in patients with drop foot, this study evaluated a sample of 15 such patients using a computerized gait analysis system, as compared to a group of 15 healthy subjects...

Dislocation following primary and revision arthroplasty is a well-recognised complication with an estimated incidence rate of 0.2-10%. We present a rare case of simultaneous bilateral total hip replacement dislocation, complicated by unilateral foot drop following closed reduction, with no improvement in neurological function at 6-month follow-up.

Takashi Watanabe, Shun Endo, Ryusei Morita
This study aimed at developing a prototype of portable FES rehabilitation system for relearning gait pattern of healthy subjects, which can measure gait information during walking applying electrical stimulation for foot drop correction or providing timing information. A gait event detection method using an inertial sensor attached on the foot was determined based on gait of healthy subjects from simultaneous measurements with pressure sensors. From the result of comparing the detected gait event timings with EMG signal of the tibialis anterior muscle during walking of healthy subjects, the toe off and the foot flat timings detected by the inertial sensor were suggested to be useful to determine the stimulation timing for the foot drop correction...

INTRODUCTION: Neurologic paralysis of the foot due to damage to the central nervous system is primarily caused by a cerebral insult. The ankle-foot orthosis (AFO), which is the classical conservative treatment option, is associated with drawbacks, e.g., increased contractures, limited mobilization from the sitting position, and cosmetic aspects. METHODS: Functional external electrostimulation (FES) is an suitable treatment method for patients with a central lesion and intact peroneal nerve...

This study investigated the clinical feasibility of combining the electromechanical gait trainer Lokomat with functional electrical therapy (LokoFET), stimulating the common peroneal nerve during the swing phase of the gait cycle to correct foot drop as an integrated part of gait therapy. Five patients with different acquired brain injuries trained with LokoFET 2-3 times a week for 3-4 weeks. Pre- and post-intervention evaluations were performed to quantify neurophysiological changes related to the patients' foot drop impairment during the swing phase of the gait cycle...

Functional Electrical Stimulation is a commonly used method in clinical rehabilitation and research to trigger useful muscle contractions by electrical stimuli. In this work, we present a stimulation system for transcutaneous electrical stimulation that gives extensive control over the stimulation waveform and the stimulation timing. The system supports electrode arrays, which have been suggested to achieve better selectivity and to simplify electrode placement. Electromyography (EMG) measurements are obtained from the active stimulation electrodes (between the stimulation pulses) or from separate surface EMG electrodes...

Peroneal nerve palsy is common. The hallmark clinical manifestation of peroneal nerve palsy is drop foot. In the drop foot condition, the ankle cannot flex, and the foot does not clear the ground during the swing phase of gait. Spontaneous nerve repair can yield complete or incomplete resolution of drop foot. Some patients with incomplete resolution are left with a drop hallux condition, in which the ankle can dorsiflex, but the hallux remains unable to dorsiflex. This has not been thoroughly discussed in the past, regarding surgical repair...
