Median-to-Ulnar Nerve Communication in Carpal Tunnel Syndrome: An Electrophysiological Study
2021
The median-to-ulnar communicating branch (MUC) is an asymptomatic variant of the upper limb innervation that can lead to interpretation errors in routine nerve conduction studies. The diagnosis of carpal tunnel syndrome (CTS) or ulnar nerve lesions can be complicated by the presence of MUC. In this study, we describe electrophysiological features of MUC in CTS patients presenting to our clinic. We enrolled MUB cases from consecutive CTS patients referred to our laboratory between the years 2014 and 2019. MUC was present in 53 limbs (36 patients) from the studied population. MUC was bilateral in 53% of patients. MUC type II was the most common subtype (74%), followed by types III and I
The Surgery of Neglected Distal Humerus Fractures in Children and Adults
2008
The restoration of function after a neglected distal humerus fracture presents a formidable challenge to the surgeon because of both the complexity of the regional anatomy and the proximity of numerous neurovascular structures. Inadequate or unstable fixation, a failure to reposition the articular fragments anatomically, prolonged post-operative immobilization, or the development of soft-tissue complications will result in substantial disability for the patient. Complications after injuries affecting a child’s elbow are common due to understimating the severity of the injury on the native X-rays where the growth plates and cartilage structures can not be seen.
MRT bei chronischer Epicondylitis humeri radialis an einem 1,0 T-Gerät - Kontrastmittelgabe notwendig?
2001
T: Is Gd-DTPA administration useful Purpose: Evaluation of the diagnostic value and confidence of contrast-enhanced MR imaging in patients with lateral epicondylitis in comparison to clinical diagnosis. Material and Methods: 42 consecutive patients with clinically proven chronic lateral epicondylitis and 10 ellbow joints of healthy controls have been examined on a 1.0 T MR-unit. Criteria for inclusion in the prospective study were: persistant pain and a failed conservative therapy. The MR protocol included STIR sequence, a native, T 2 -weighted, fat-supressed TSE sequence, and a Flash-2-D sequence. Also, fatsupressed, T 1 -weighted SE sequences before and after administration of Gd-DTPA con…
Maximal isometric muscle strength and anthropometry in 75-year-old men and women in three Nordic localities
2007
Isometric maximal strength of hand grip, elbow flexion, knee extension, trunk extension and trunk flexion was studied in representative samples of 75-year-old residents of 3 Nordic localities: Glostrup in Denmark, Gothenburg in Sweden and Jyvaskyla in Finland. The study forms a part of a wider comparative research project analyzing the functional capacity and health of 75-year-olds in these towns. The strength measurements were carried out using standardized techniques and identical dynamometers. The results showed that the strength values of the limb muscles were significantly lower among the 75-year-olds in Jyvaskyla, both in absolute values and in relative units (N/kg body mass). For the…
Retrograde Nailing of Humeral Shaft Fractures
1998
The use of intramedullary nailing in the upper extremity is still controversial. Those who have experience with antegrade nailing have either great enthusiasm or strong criticism for the procedure. Criticism of the procedure is because of the trauma that can occur to the rotator cuff and possible impingement syndrome, which can occur after antegrade nail insertion. The technique of retrograde nail insertion with the unreamed humeral nail is described in detail. In a series of 190 retrograde nailings performed in a prospective multicenter study, the most frequent intraoperative problems were fissure or avulsion at the entry portal (n = 8; 4.2%) and secondary radial nerve palsy (n = 8; 4.2%).…
Sulcus ulnaris Syndrom nach Traumen im Ellenbogenbereich
2008
For a large scaled test 52 patients with anterior transposition of the ulnar nerve and 62 patients with elbow injuries were examined by questionnaire, physical examination and electroneurography. In conformity with existing literature 24 patients out of 52 suffering from cubital tunnel syndrome had an elbow trauma previously. To our great surprise in seven patients out of 46 with elbow injuries a cubital tunnel syndrome could be found for the first time. The cubital tunnel syndrome appears to be a frequent complication of elbow injuries. Besides the well known fractures of the medial epicondyle and pericondylar fractures leading to cubital tunnel syndrome, in our study fractures of the head…
Circumferential graft for elbow instability
2019
For those patients with instability of the medial and lateral sided of the elbow, there is a place for a circumferential graft. This has the main advantage of simplifying the bone tunnel creation and graft fixation, compared to having both medial- and lateral-sided reconstructions.
Constant Power Model in Arm Rotation—A New Approach to Hill’s Equation
2014
The purpose of this study was to further develop the constant power model of a previous study and to provide the final solution of Hill’s force-velocity equation. Forearm and whole arm rotations of three different subjects were performed downwards (elbow and shoulder extension) and upwards (elbow and shoulder flexion) with maximum velocity. These arm rotations were recorded with a special camera system and the theoretically derived model of constant maximum power was fitted to the experimentally measured data. The moment of inertia of the arm sectors was calculated using immersion technique for determining accurate values of friction coefficients of elbow and whole arm rotations. The experi…
Movement Variability Increases With Shoulder Pain When Compensatory Strategies of the Upper Body Are Constrained
2017
[DE] This cross-sectional study analyzed the influence of chronic shoulder pain (CSP) on movement variability/kinematics during humeral elevation, with the trunk and elbow motions constrained to avoid compensatory strategies. For this purpose, 37 volunteers with CSP as the injured group (IG) and 58 participants with asymptomatic shoulders as the control group (CG) participated in the study. Maximum humeral elevation (Emax), maximum angular velocity (Velmax), variability of the maximum angle (CVEmax), functional variability (Func_var), and approximate entropy (ApEn) were calculated from the kinematic data. Patients' pain was measured on the visual analogue scale (VAS). Compared with the CG, …
Ultrasound evaluation of joint damage and disease activity in adult patients with severe haemophilia A using the HEAD‐US system
2021
Introduction The Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) system and scoring scale has proven to be an accurate and time-efficient imaging method for identifying joint damage in patients with haemophilia. Aim Observational, multicentre, cross-sectional study conducted in 8 centres in Spain that assessed the joint status of adult patients with severe haemophilia A (SHA) using HEAD-US. Methods Joint status of the elbow, knee and ankle was evaluated in adults with SHA receiving on-demand (OD) treatment, or primary (PP), secondary (SP), tertiary (TP) or intermittent (IP) prophylaxis. Results Of the 95 patients enrolled, 87 received prophylaxis (6.3% PP, 38.9% SP, 43.2% …
