    The Nearly Invisible Intraneural Cyst: a New and Emerging Part of the Spectrum

    NEUROSURGICAL FOCUS Neurosurg Focus 42 (3):E10, 2017 The nearly invisible intraneural cyst: a new and emerging part of the spectrum Thomas J. Wilson, MD,1 Marie-Noëlle Hébert-Blouin, MD,2 Naveen S. Murthy, MD,3 Joaquín J. García, MD,4 Kimberly K. Amrami, MD,3 and Robert J. Spinner, MD1 Departments of 1Neurosurgery, 3Radiology, and 4Laboratory Medicine and Pathology, Mayo Clinic, Rochester, Minnesota; and 2Department of Neurosurgery, McGill University Health Centre, Montreal, Quebec, Canada OBJECTIVE The authors have observed that a subset of patients referred for evaluation of peroneal neuropathy with “negative” findings on MRI of the knee have subtle evidence of a peroneal intraneural ganglion cyst on subsequent closer inspection. The objective of this study was to introduce the nearly invisible peroneal intraneural ganglion cyst and provide illustrative cases. The authors further wanted to identify clues to the presence of a nearly invisible cyst. METHODS Illustrative cases demonstrating nearly invisible peroneal intraneural ganglion cysts were retrospectively reviewed and are presented. Case history and physical examination, imaging, and intraoperative findings were reviewed for each case. The outcomes of interest were the size and configuration of peroneal intraneural ganglion cysts over time, relative to various interventions that were performed, and in relation to physical examination and electrodiagnostic find- ings. RESULTS The authors present a series of cases that highlight the dynamic nature of peroneal intraneural ganglion cysts and introduce the nearly invisible cyst as a new and emerging part of the spectrum. The cases demonstrate changes in size and morphology over time of both the intraneural and extraneural compartments of these cysts.

  • Trigger Finger

    Trigger Finger

    PATIENT EDUCATION Trigger Finger Trigger Finger "Trigger finger" sounds like a malady that might affect gunslingers or hunters. In fact, this common condition results in a finger bent as if to pull a trigger. People over 40 years of age with a history of diabetes or rheumatoid arthritis are especially at risk to develop this condition. How it develops Although the exact cause of trigger finger is unknown, the progression of the condition is well documented. Trigger finger involves the tendons and pulleys in the hand that bend the finger. The tendons connect the muscles of the forearm with the bones of the fingers. Each tendon is covered by a slick lining or sheath. When you bend your fingers, the tendons glide back and forth, guided by a restraining pulley or yoke. When the tendon sheath becomes inflamed, it swells and may develop a knot or thickening in the tendon. The knot passes through the pulley as the finger bends, but gets stuck as the finger straightens. This causes further irritation and results in a vicious circle of irritation, swelling, catching and more irritation until finally, the finger locks in a bent position. Diagnosis No X­rays are needed to diagnose trigger finger. Your doctor will examine your hand and fingers, and use the findings to make the diagnosis. The finger may be swollen and there may be a bump, or nodule, over the joint in the palm of the hand. The finger may be stiff and painful. Although it may seem that the problem is in the knuckles, it is actually at the joint nearest the palm of the hand.

    CONSTRUCTION WORK and CUMULATIVE TRAUMA DISORDERS What Are Cumulative Trauma Disorders?

Cumulative trauma disorders (CTDs) also known as repetitive strain injuries, repetitive motion disorders, overuse syndrome, and work-related musculoskeletal disorders are the largest cause of occupational disease in the United States and the most frequently reported type of occupational disease in Connecticut. CTDs are injuries of the musculoskeletal system (joints, muscles, tendons, ligaments, nerves, and blood vessels) which are caused by over use as a result of stressful work over a period of time. CTDs are usually caused by a combination of the following risk factors common to construction work: • repetitive motions • forceful exertions - pulling, pushing, lifting, and gripping • awkward postures - body positions that are not the natural resting position • static postures - body positions held without moving • mechanical compression of soft tissues in the hand against edges or ridges, such as using tools or objects which press against the palm • fast movement of body parts • vibration, especially in the presence of cold conditions • lack of sufficient recovery time (rest breaks, days off), which will increase the risk of developing a CTD by any of the above factors. Cumulative trauma disorders most often occur in the upper body. Common symptoms of CTDs include pain and swelling of the body parts that are performing work duties involving the above risk factors. Although back injuries are excluded from the definition of CTDs, back injuries are often caused by similar risk factors and occur quite frequently in construction workers.

    De Quervain's Release Standard of Care PT

    BRIGHAM & WOMEN’S HOSPITAL Department of Rehabilitation Services Physical Therapy Standard of Care: de Quervain’s Syndrome: Surgical Management Physical Therapy management of the patient who had a release of the first extensor compartment. Case Type/Diagnosis: (diagnosis specific, impairment/dysfunction specific) 11 Since the first description of “washerwoman’s sprain” tenosynovitis of the first dorsal compartment has become a commonly recognized inflammatory disorder. The most radial of the extensor compartments on the dorsum of the wrist is occupied by the tendons of the extensor pollicis brevis and abductor pollicis longus. The tendons are enveloped in an osseofibrous canal lined by synovium, which, when subjected to excessive or repetitive mechanical stresses, responds in a characteristic fashion distinguished by pain, swelling, and limitation of motion of the thumb. In 1895,Fritz de Quervain, a Swiss surgeon, 1 was first credited with the recognition of this disease and so it bore his name. More accurately, Tillaux 2 and Gray 3 referred to this disorder before de Quervain. Anatomy: Twenty-four extrinsic tendons cross the wrist and provide power and dexterity in the hand. Each tendon passes through a series of tight fibrous -osseous canals designed to optimize the balance between motion and force production by maintaining the tendon in close approximation to the joint or joints it controls. There are six separate compartments under the dorsal carpal ligament each lined with a separate synovial sheath membrane. The first one is over the radial styloid and it contains the abductor pollicis longus and the extensor pollicis brevis tendons. These tendons pass through an unyielding osteoligamentous tunnel formed by a shallow groove in the radial styloid process and a tough overlying roof composed by the transverse fibers of the dorsal ligament.

Trauma & Orthopaedics, All India Institute of Medical Sciences, Bhubaneswar, IND Corresponding author: Sudarsan Behera, [email protected] Disclosures can be found in Additional Information at the end of the article Abstract Cystic lesion around knee usually presents as painless swelling and diagnosed incidentally by imaging for any internal derangement of the knee. Few cases presented with pain. Intra- tendinous patellar ganglion is very rare in location for the disease. Ganglionic cyst usually treated by aspiration followed by steroid and surgical excision in some cases. We reported a case with anterior knee pain due to patellar intra-tendinous ganglion cyst which treated conservatively with no recurrence even after one year. Categories: Radiology, Orthopedics, Anatomy Keywords: ganglion cyst, patellar intra-tendinous sheath, knee pain Introduction A ganglion is a benign cystic mass containing clear high-viscosity mucinous fluid with a dense fibrous connective tissue capsule lined by flat spindle-shaped cells that is rich in hyaluronic acid and other mucopolysaccharides [1, 2]. Ganglia usually arises from periarticular locations with a variable for predilection intra-articular, extra-articular soft tissue, intraosseous and rarely from periosteal locations [1,3,4]. Majority of the patients are asymptomatic and diagnosed incidentally on imaging. Clinical presentation depends on the location and size of the ganglion.
