PURPOSE: To assess the use of preoperative, dynamic ultrasound to predict ulnar nerve instability following in situ decompression for cubital tunnel syndrome. METHODS: Prior to undergoing in situ decompression, 43 consecutive patients underwent dynamic ultrasound to assess the stability of the ulnar nerve during elbow flexion. The dynamic ultrasound findings were compared with the intraoperative assessment of nerve stability following in situ decompression. RESULTS: The preoperative dynamic ultrasound agreed with intraoperative findings in 38 of 43 patients (88%)...

Botulinum toxin (BT) is widely prescribed by physicians for managing spasticity post stroke. In an ongoing study, we examine the spatial pattern of muscle activity in biceps brachii of stroke survivors before and after receiving BT, examined over the course of 11 weeks (2 weeks before - 9 weeks after). We hypothesize that BT alters muscle electrophysiology by disrupting fiber neuromuscular transmission in an inhomogeneous manner and we seek to detect these changes using grid surface electromyography (sEMG)...

Ulnar neuropathy at the elbow is the second most common entrapment neuropathy of the upper extremity. Yet, there is a paucity of literature focusing on the imaging appearance following surgical decompression of the ulnar nerve at the elbow. Diagnostic imaging studies obtained after surgical decompression at The University of Michigan were reviewed and imaging findings were documented. We aim to describe the various techniques of ulnar nerve decompression and corresponding post-operative appearance on imaging...

OBJECTIVE: To investigate the relationship between tendon structural changes determined by static ultrasound images (US) and sensory changes using quantitative sensory testing (QST), and clinical measures in lateral epicondylalgia. MATERIALS AND METHODS: Both elbows of 66 adult participants with a clinical diagnosis of lateral epicondylalgia were investigated. Using a standardised ultrasound image rating scale, common extensor hypoechogenicity, heterogenicity, neovascularity, and bony abnormalities at the enthesis were scored, and tendon thickness (longitudinal and transverse plane) was measured by a trained assessor...

About 10% of supracondylar humerus fractures in children are associated with distal ischemia. In case of acute limb ischemia after reduction and fixation, it is recommended to explore the brachial artery surgically without delay. However, there is no consensus on the management of intermediate situations, like a perfused hand with a weak pulse after fracture fixation. A 6-year-old boy presented a displaced Gartland type III supracondylar humerus fracture with no radial or ulnar pulse and hand ischemia. Immediately after closed reduction and internal fixation, the pulses were still missing...

BACKGROUND: Proximal brachial plexus blocks can lead to an extended period of motor paralysis and delay the return of motor function. This could influence patient satisfaction, and extend hospitalizations. The aim of the study is to compare a selective distal nerve block of the arm to a proximal axillary block, both ultrasound-guided, in terms of their motor block intensity of the elbow. Our hypothesis is that a selective nerve block of the arm would result in a different motor block of the elbow, compared to the axillary block...

We investigated alterations in material properties such as elasticity and viscoelasticity of stroke-affected muscles using ultrasound induced shear waves and mechanical models. We used acoustic radiation force to generate shear waves along fascicles of biceps muscles and measured their propagation velocity. The shear wave data were collected in muscles of 13 hemiplegic stroke survivors under passive conditions at 90°, 120°, and 150° elbow flexion angles. In a viscoelastic medium, as opposed to a purely elastic medium, the shear wave propagation velocity depends on the frequency content of the induced wave...

BACKGROUND: Massive and irreparable rotator cuff tears are difficult to manage surgically. One technique is to use a synthetic polytetrafluoroethylene (PTFE) patch to bridge the tear. However, there is little information regarding the outcomes of this procedure. PURPOSE: To determine the ≥2-year outcomes of patients for whom synthetic patches were used as tendon substitutes to bridge irreparable rotator cuff defects. STUDY DESIGN: Case series; Level of evidence, 4...

A 19-year-old female collegiate swimmer presented to our sports medicine clinic with a history and physical examination consistent with right ulnar neuropathy at the cubital tunnel. Diagnostic ultrasound (US) revealed compression of the ulnar nerve under the cubital tunnel retinaculum (CTR) with nerve swelling proximal to the site of compression. Electrodiagnostic studies confirmed the diagnosis of a moderate to severe ulnar neuropathy at the elbow. Treatment consisted of an US-guided decompression of the ulnar nerve in the cubital tunnel by cutting the CTR using a rotated stylet "v" cutting technique...

REVIEW
C Tesch
Focused sonography of the musculoskeletal system in the emergency room should be done for time-effective and symptom-oriented detection of suspected findings. Analogous to other point-of-care ultrasound in emergency medicine, it is by definition not a complete ultrasound examination of the respective organ (e.g., shoulder, elbow). It allows detection of important findings (luxation, effusion, fracture or rupture) with good to excellent diagnostic accuracy. Afterwards computed tomography, magnetic resonance imaging or complete sonographic examination (according to the guidelines of the working group Bewegungsorgane der Deutschen Gesellschaft für Ultraschall in der Medizin, which are identical to those of the working group Orthopädie und Unfallchirurgie) should be added as clinically required...

PURPOSE OF THE STUDY When treating tears of the distal biceps brachii muscle tendon, we repeatedly noticed a difference between the preoperative ultrasound findings and the operative findings. The aim of the study was to retrospectively correlate these findings in order to determine the sensitivity of the ultrasound examination in everyday orthopaedic practice. Moreover, we compared the results and complications of surgical treatment through two operative techniques used at our department. MATERIAL AND METHODS In the 2004-2016 period 20 patients underwent a surgery at our department for total tear of the distal tendon of the biceps brachii muscle...

Although triceps tendon ruptures can result from a traumatic incident, chronic overuse causing degenerative changes to the insertion and leading to a complete or partial rupture is more common. In our practice, we have found that anabolic steroid abuse by weightlifters is the most common predisposing factor. The initial diagnosis is often missed. A thorough clinical examination is imperative to avoid missing a partial or complete rupture. Ultrasound or magnetic resonance imaging can confirm the diagnosis. Early diagnosis increases the chance of a direct repair...
