De Quervain disease (DQVD) is one of the most common causes of lateral wrist pain and can lead to significant disability. The current case involves a right-handed, middle-aged, female patient with severe lateral wrist pain due to DQVD. Her pain was not responsive to oral non-steroidal anti-inflammatory drugs, rehabilitation, and repeated corticosteroid injections. Because she refused surgical intervention, we performed ultrasound-guided methotrexate injections (four times). After the injections, dramatic pain relief, functional improvement, and reduction of the thickness of the retinaculum and tendons in the first dorsal extensor compartment of the wrist were noted...

Activation of motor-related regions with illusory kinesthesia had been suspected to contribute toward pain alleviation. We used electroencephalography (EEG) to assess the sensorimotor cortex activation during illusory kinesthesia by vibratory tendon stimulation in patients who were in pain. We investigated the relationship between the sensorimotor cortex and postoperative pain to clarify the analgesia mechanism. Patients who had undergone distal radius fracture surgery were studied. A hand massager provided the vibration stimulus for the illusory kinesthesia on the extensor digitorum muscle at the nonaffected hand's wrist joint on 7 consecutive days starting 1 day after surgery...

Chronic sagittal band injury with tendon dislocation of the extensor digitorum communis in the hand often requires operative stabilization. Various surgical techniques have been reported to repair and reconstruct the sagittal band. Nonetheless, most of the techniques are technically demanding and require donor graft. In this case report, we report a novel surgical technique to centralize and stabilize the tendon by reattaching the radial sagittal band with anchor sutures. The advantages of this new technique are simple, no donor morbidity and stable repair to restore the normal biomechanics of the tendon...

STUDY DESIGN: Case report. INTRODUCTION: Injuries to adjacent fingers with differing extensor tendon (ET) zones and/or sagittal band pose a challenge to therapists as no treatment guidelines exist. PURPOSE OF THE STUDY: This report highlights how the relative motion flexion/extension (RMF/RME) concepts were combined into one orthosis to manage a zone IV ET repair (RME) and a zone III central slip repair (RMF) in adjacent fingers (Case 1); and how a single RME orthosis was adapted to limit proximal interphalangeal joint motion to manage multi-level ET zone III-IV injuries and a sagittal band repair in adjacent fingers (case 2)...

De Quervain's tenosynovitis is a repetitive strain injury involving synovial inflammation of the tendons of the first extensor compartment of the wrist. It is relatively common in the general population, and is the most common radial-sided tendinopathy seen in athletes. Identifying a genetic marker associated with de Quervain's tenosynovitis could provide a useful tool to help identify those individuals with an increased risk for injury. A genome-wide association screen was performed using publically available data from the Research Program in Genes, Environment and Health (RPGEH) including 4,129 cases and 98,374 controls...

BACKGROUND: Spasticity and spastic dystonia are two separate phenomena of the upper motor neuron syndrome. Spasticity is clinically defined by velocity-dependent hypertonia and tendon jerk hyperreflexia due to the hyper-excitability of the stretch reflex. Spastic dystonia is the inability to relax a muscle leading to a spontaneous tonic contraction. Both spasticity and spastic dystonia are present in patients who are at rest; however, only patients with spasticity are actually able to kept their muscles relaxed prior to muscle stretch...

Ruptures of the tendon of the tibialis anterior muscle tend to occur in the context of degenerative impairments. This mainly affects the distal avascular portion of the tendon. Owing to the good compensation through the extensor hallucis longus and extensor digitorum muscles, diagnosis is often delayed. In addition to the clinical examination, magnetic resonance inaging (MRI) diagnostics are of particular importance, although damage or rupture of the tendon can also be demonstrated sonographically. Therapeutic measures include conservative or operative measures, depending on the clinical symptoms...

BACKGROUND: The principle of relative motion has allowed patients to regain a higher degree of hand function, while protecting extensor tendon repairs. The purpose of this study was to determine whether the principle of relative motion could be a viable method to protect a flexor tendon repair. METHODS: Four fresh-frozen cadaver arms were each mounted on a testing apparatus (wrist in 30° of extension, metacarpophalangeal [MCP] joints blocked to 70°-80°). A minimum of 11 N was used to cyclically load the flexor digitorum profundus and extensor digitorum communis tendons to maximum allowable flexion and extension for 25 cycles...

PURPOSE: The state-of-the-art tendon transfer surgery for high median-ulnar nerve palsy involves directly suturing four finger flexor tendons to one wrist extensor muscle. This couples finger flexion limiting the patient's ability to grasp objects. Therefore, we propose a new approach to attach a novel passive implant to the extensor digitorum longus tendon in order to create a differential mechanism in situ. The implant is expected to enable the fingers to adapt to an object's shape during grasping...

Hand musculoskeletal models provide a valuable insight into the loads withstood by the upper limb; however, their development remains challenging because there are few datasets describing both the musculoskeletal geometry and muscle morphology from the elbow to the finger tips. Clinical imaging, optical motion capture and microscopy were used to create a dataset from a single specimen. Subsequently, a musculoskeletal model of the wrist was developed based on these data to estimate muscle tensions and to demonstrate the potential of the provided parameters...

A distal femoral extension osteotomy with patellar tendon advancement (DFEO+PTA) is a common treatment for individuals with cerebral palsy (CP) who walk in crouch. Musculoskeletal modeling suggests that the typical patella baja position post-DFEO+PTA may limit one's abilities to perform sit-to-stand (STS) tasks; however, STS function has not been assessed. Our purpose was to compare how well individuals who received a DFEO+PTA can perform a 5-times STS test (FTSST) eight or more years after surgery compared to their peers who did not receive a DFEO+PTA (non-DFEO+PTA group)...

Simultaneous occurrence of tibial tubercle fracture and patellar tendon avulsion with double-hit injury of the knee extensor mechanism is an extremely rare condition. However, they become more frequent due to increased participation in sports and high-energy recreational activities at younger age. It represents a frequently missed diagnosis; therefore, high index of suspicion is required for the diagnosis of such injuries to avoid delays in the treatment which would lead to possible suboptimal functional outcome...

Menkes disease (MD) (OMIM: 309400) is also known as kinky hair disease, trichopoliodystrophy, and steely hair. A 7-months-old, male infant presented to our outpatient department in June 2016 with history of developmental delay and seizures. Seizures started at 3 months of age and worsened progressively to clusters of extensor spasms. Physical examination showed sparse and kinky hair. Neurological examination revealed a central hypotonia with marked decrease in muscle power with normal deep tendon reflexes. The serum ceruloplasmin level and serum copper level were decreased...

Anthony L Hessel, Kiisa C Nishikawa
Negative work occurs in muscles during braking movements such as downhill walking or landing after a jump. When performing negative work during stretch-shortening cycles, viscoelastic structures within muscles store energy during stretch, return a fraction of this energy during shortening, and dissipate the remaining energy as heat. Because tendons and extracellular matrix are relatively elastic rather than viscoelastic, energy is mainly dissipated by cross bridges and titin. Recent studies demonstrate that titin stiffness increases in active skeletal muscles, suggesting that titin contributions to negative work may have been underestimated in previous studies...
