Luis Cartier R, Andrés Gallardo V
Liquefied hydrocarbon gas, such as propane is considered safe. However there are reports that voluntary exposure to liquefied gas at least could originate hallucinatory states. We report a 20 years old woman who was found in a coma with extensor muscle hypertonia, brisk tendon reflexes and extensor plantar (Babinski) responses after being exposed to propane gas. The brain magnetic resonance imaging (MRI) showed lesions in both hippocampi and white matter in the oval center. The patient had a normal oxygen saturation of 98%, a carboxyhemoglobin of 1...

BACKGROUND: The posterior approaches to the elbow are considered as to allow an excellent joint exposure for total elbow arthroplasty. One complication that is well recognized is the insufficiency of the extensor mechanism in particular with the patients with poor tendon quality as in the rheumatoid diseases. The purpose of this paper is to present a new triceps-splitting exposure for total elbow arthroplasty used in rheumatoid patients with their preliminary results. METHODS: Fifteen consecutive patients with rheumatoid disease at grades III to V of the Larsen grading scale underwent total elbow replacement using the new triceps-splitting exposure called anconeus-triceps lateral flap and it preserves the integrity of the medial proper triceps tendon...

Knee extensor mechanism rupture is a serious complication of total knee arthroplasty (TKA). Its prevalence ranges from 1 to 10% and it is commonly observed as a chronic multifactorial pathology with the patellar tendon as the most common site of rupture. Knee extensor mechanism reconstruction can be performed using allogenic or synthetic grafts. In the literature it is still not clear whether one of these techniques is superior to the other and the choice is usually tailored to the patient case by case. Allografts allow better restoration of the anatomical landmarks, whereas the mesh technique is more reproducible and the graft does not elongate over time...

BACKGROUND: Isolated tuberculous tenosynovitis and bursitis are rare among musculoske let al tuberculosis, but it is one of the major causes for chronic tendon sheath infection in developing countries. In hand, it is usually presented as a compound palmer ganglion (radio ulnar bursa), tenosynovitis of the flexer tendon sheaths and very few cases of tubercular tenosynovitis affecting the extensor tendons also are reported. CASE PRESENTATION: We are reporting a rare case of tuberculous extensor tenosynovitis with rupture of the extensor digitorum tendon in an elderly Indian man...

The complex inter-segmental forces that are developed across an extended knee by body weight and contraction of the quadriceps muscle group transmits an anteriorly-directed force on the tibia that strain the anterior cruciate ligament (ACL). We hypothesized that a relationship exists between geometry of the knees extensor mechanism and the risk of sustaining a non-contact ACL injury. Geometry of the extensor mechanism was characterized using MRI scans of the knees of 88 subjects that suffered their first non-contact ACL injury and 88 matched control subjects with normal knees that were on the same team...

Tendon rupture in dogs is generally the result of a direct trauma. This report described the use of adjacent muscle autogenic fascial graft for reconstruction of distal rupture of long digital extensor tendon in a dog. A two-year-old male mix breed dog, was presented with a non-weight bearing lameness of the right hind limb and a deep rupture of lateral side of right tarsus. History taking revealed that this rupture appeared without any apparent cause, when walking around the farm, three days before. Radiography was done and no fracture was observed...

Jae Hoon Lee, Jong Hun Baek, Jung Seok Lee
Subluxation of the extensor tendon results from a disruption to the sagittal band at the metacarpophalangeal joint. When conservative treatment fails to correct the subluxation, surgical treatment may be necessary. Surgical techniques for chronic cases vary in graft source and graft pathway. We present a surgical technique to recentralize and stabilize the extensor tendon using a residual ruptured sagittal band. This technique is simple and effective without donor site morbidity and seems to provide potential biomechanical advantages by restoring nearly normal anatomy...

MATERIAL AND METHODS: Traumatic dislocation of the extensor tendon over the metacarpophalangeal (MCP) joint is a rare lesion that is caused by the dysfunction or rupture of the sagittal band, which is an important stabilizing structure of the extensor tendon. This mechanical alteration presents itself as instability that affects function and may cause pain or snapping during finger motion. The diagnosis is made when ulnar dislocation of the extensor tendon is observed over the MCP joint...

During a routine dissection of an adult embalmed male cadaver for educational purpose in the department of anatomy at AIIMS, New Delhi, India, a rare unilateral variation of extensor digitorum longus (EDL) was found which is a muscle of anterior compartment of the leg. There was a split tendon of EDL muscle in the anterior compartment of left leg which became a common tendon in front of the ankle joint. This common tendon of EDL muscle again divided into four slips and were inserted in to the lateral four toes...

Traumatic injuries to the knee are common in emergency medicine. Bedside ultrasound (US) has benefits in the rapid initial detection of injuries to the patella. In addition, US can also quickly detect injuries to the entire knee extensor mechanism, including the quadriceps tendon and inferior patellar ligament, which may be difficult to diagnose with plain radiographs. While magnetic resonance imaging remains the gold standard for diagnostic evaluation of the knee extensor mechanism, this can be difficult to obtain from the emergency department...

BACKGROUND: To evaluate the efficiency of the percutaneous 18-G needle technique in releasing the fibro-osseous sheath over the first dorsal extensor compartment of the hand. METHODS: Using anatomic landmarks, percutaneous release was performed with an 18-G needle on 48 wrists of 24 cadavers. The specimens were then dissected and examined for the completeness of the first dorsal extensor compartment release and any tendon or neurovascular injuries. The tunnel length, number of abductor pollicis longus and extensor pollicis brevis tendons, presence of an intertendinous septum, and the effects of these parameters on percutaneous release were evaluated...

: Congenital hypoplasia of the extensor tendon central slip is a rare entity. This article describes the clinical characteristics in a series of 22 fingers in 16 patients (mean age: 10 months), and the outcomes of conservative treatment. Nine of 22 fingers were classified as slender or hypoplastic. Treatment with bracing was successful in 21 digits, resulting in full active extension of the proximal interphalangeal joint at a mean of 8.5 months after treatment. Bracing was unsuccessful in one digit, in which operative treatment resulted in a successful outcome...

Variations of radial artery, in both its course and branching pattern in the anatomical snuffbox, are clinically significant for the plastic surgeons, cardiologists, and radiologists. Reports on its abnormal high origin and subsequent superficial course have been well documented. Herein, we report an unusual superficial branch of the radial artery given off before its entry into the palm by passing between the two heads of first dorsal interosseous. It eventually divided into princeps pollicis and radialis indicis arteries at the first web space of palm as a unique vascular variation...

PURPOSE: The purpose of this study was to compare mid-term results of three different reconstructive techniques for chronic patellar tendon disruption after total knee arthroplasty (TKA). Several surgical techniques have been proposed, but to date it is still unclear which is the best solution. The hypothesis was that allografts provide better functional results than autografts in restoring a correct joint function. METHODS: Twenty-one reconstructions were performed in twenty-one patients (three groups of seven patients) with chronic patellar tendon lesion following TKA...

BACKGROUND: Published data regarding the structure of the quadriceps tendon are diverse. Dissection of the quadriceps muscle group revealed that beside the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis a fifth muscle component- named the tensor vastus intermedius consistently fused into quadriceps tendon. It can be hypothesized that all these elements of the extensor apparatus of the knee joint must also be represented in the quadriceps tendon. This study investigated the multi-layered quadriceps tendon with special emphasis on all components of the quadriceps muscle group including the newly discovered tensor vastus intermedius...

BACKGROUND: Ultrasonography can be used in early Rheumatoid Arthritis to determine and to follow parameters of joint inflammation, such as effusion, synovitis, and marginal erosion that can be radiologically occult. We therefore planned a study to investigate whether Ultrasonography could provide information on signs of inflammation and destruction in Rheumatoid Arthritis affected finger joints that was not available with Radiography and compared it to the information provided by Magnetic resonance imaging...

Patellar sleeve fractures make up greater than 50% of all patellar fractures. They are essentially only seen in the pediatric population because of the thick periosteum and the distal patellar pole apophysis in this group. These fractures can lead to complications if not treated appropriately and in a timely fashion. Complications of missed or untreated patellar sleeve fractures include patella alta, anterior knee pain, and quadriceps atrophy. These can all result in severe limitations in activity. The authors describe a case of a 16-year-old boy who sustained a patellar sleeve fracture 3 years prior to presentation...
