Distal biceps tendon ruptures are a result of an eccentric load onto a flexed elbow and can lead to loss of flexion and supination strength. Surgical treatment is a well-accepted treatment that can improve flexion and supination strength, however, can be associated with a number of surgical complications. The case presented here describes a vascular injury sustained during a distal biceps tendo...

We describe a patient who complained of jerking of the right forearm on writing. Active pronation of his arm produced several beats of pronation/supination tremor. A burst of tremor also could be elicited by tendon taps to the volar surface of the wrist, to the finger extensors, and to pectoralis major, and by forcible supination of the wrist delivered by a torque motor. The subject's writing d...

A 26 year old male reported with gross limitation of pronation and supination of right forearm 8 week after a vehicular accident. X-Ray of the elbow showed isolated radial head dislocation without any associated fracture. It was treated with radial head excision with almost full restoration of movements postoperatively. The case is presented because of rarity of this injury and the tendency to ...

In force myography (FMG) limb movement is detected by measuring muscle contraction intensity in terms of forces. this work, FMG used to detect forearm movements i.e. flexion, extension, pronation, supination and steady-state. FMG, sensors are conventionally located at supinator/pronator muscles pronation/supination movement. paper, a new approach also including flexion/extension steady-state po...

Zusammenfassung Die Ruptur der distalen Bizepssehne tritt am häufigsten bei Männern im mittleren Alter auf (30 bis 50 Jahre). Der typische Mechanismus ist die exzentrische Belastung in strecknaher Ellbogenstellung Supination, wobei diese Verletzung mit Kraftsport und körperlich belastender Tätigkeit assoziiert ist. Epidemiologische Daten weisen eine Zunahme von Bizepsrupturen den letzten Jahrze...

BACKGROUND Pulled elbow (nursemaid's elbow) is a common injury in young children. It often results from a sudden pull on the arm, usually by an adult or taller person, which pulls the radius through the annular ligament, resulting in subluxation (partial dislocation) of the radial head. It can also be caused by a fall or twist. The child experiences sudden acute pain and loss of function in the...

AIM To provide a "patient-normalized" parameter in the proximal forearm. METHODS Sixty-three cadaveric upper extremities from thirty-five cadavers were studied. A muscle splitting approach was utilized to locate the posterior interosseous nerve (PIN) at the point where it emerges from beneath the supinator. The supinator was carefully incised to expose the midpoint length of the nerve as it p...

PURPOSE To show biomechanically that the brachioradialis (BR) muscle can be transferred to restore key pinch and forearm pronation simultaneously. METHODS Nine fresh-frozen forearms were thawed and instrumented with a custom muscle-tendon excursion jig. Maximum BR muscle-tendon excursion was measured with the wrist and thumb mobile. Muscle-tendon excursion then was measured from 60 degrees of...

PURPOSE For severe forearm injuries such as an Essex-Lopresti fracture-dislocation, functional reconstruction necessitates repair of the interosseous ligament (IOL) to restore normal load sharing between the radius and ulna. Locating or tensioning such a reconstruction improperly can lead to abnormal load sharing and/or restriction of forearm rotation. The normal IOL strains should indicate the...

8 Abstract 9 Purpose The aim of this study was to provide guidance 10 on the safe zones for the exposure of the proximal radius by 11 measuring the distance from the PIN to various anatomical 12 landmarks in the proximal forearm in pronation and 13 supination. 14 Methods Twenty cadaveric arms were used for this study. 15 On the anterior aspect of the forearm, the distance between 16 insertion o...
