INTRODUCTION It is well known that the biceps functions mainly as an elbow flexor and forearm supinator. In vivo elbow flexion and forearm supination strength testing after rupture of the long head of the biceps tendon has shown decreases of 0-16% and 0-21%, respectively [1,2]. Although many studies have attempted to identify the role of the long head of the biceps brachii muscle in elbow flexi...

A nine year old girl with a congenital above-elbow amputation was supplied with a myoelectrically controlled arm prosthesis at the Regional Hospital, Orebro, Sweden, in May 1978. The prosthesis was equipped with an artificial hand as well as an elbow joint. The latter was designed at New York University, for switch control but adapted to myoelectric control in the Department of Clinical Neuroph...

OBJECTIVE To evaluate the influence of elbow and forearm range of motion on the distal excursion of the long head of the biceps (LHB). METHODS The distal excursion of the LHB after tenotomy of the shoulders of eight cadavers was ascertained by measuring the distance between a point marked out on the LHB, 3 cm from the anterolateral border of the acromion, and its position at different degrees...

Congenital bilateral humeroradioulnar fusion of the elbow is rare. Many patients tolerate unilateral elbow stiffness very well, but bilateral fixed elbows are very disabling. We report the management of a 13-year-old patient using the Ilizarov technique. The left elbow was ankylosed in 70 degrees flexion. It was gradually lengthened through an osteotomy across the fused elbow and flexed through...

Rupture of the Long Head of Biceps tendon (LHB) results in varying elbow flexion strength deficit (mean deficit: 8%, S.D. 12% of mean) (Mariani et al. 1988). This variability in strength is interesting because it is previously unexplained. Observations of musculoskeletal parameters also exhibit variability (Murray et al. 2000). We hypothesize that the variation in elbow flexion strength in heal...

Parkinsonian rigidity has been thought to be constant through a full range of joint angle. The aim of this study was to perform a detailed investigation of joint angle dependency of rigidity. We first measured muscle tone at the elbow joint in 20 healthy subjects and demonstrated that an angle of approximately 60° of flexion marks the division of two different angle-torque characteristics. Then...

BACKGROUND Flexion of one elbow is essential to enable children with arthrogryposis to achieve independent function such as self-feeding and self-care of the face and hair. We analyzed the outcomes of posterior elbow capsulotomy with triceps lengthening for the treatment of elbow extension contractures in a series of children with arthrogryposis multiplex congenita. METHODS The medical record...

We present the long-term results of pectoralis major transfer to restore elbow flexion in seven patients (ten procedures). The early results in all the patients were encouraging but with longer follow-up a gradual and progressive flexion deformity was observed with a decrease in the arc of flexion in eight elbows, reaching > or = 90 degrees in all cases. The results of pectoralis major transfer...

Abnormal synergies in the paretic shoulder and elbow of hemiparetic subjects were quantified during maximal voluntary contractions (MVCs) in 27 subjects with a history of stroke and 8 age-matched control subjects. A six-axis load cell allowed simultaneous measurement of the primary torque the subject was attempting to maximize and the secondary torques at other joint actions. For example, durin...

Joint stiffness is a common complication of elbow trauma. Treating elbow stiffness is challenging, especially in patients with severe elbow stiffness with distal humeral nonunion. To improve treatment outcomes, the authors applied a hinged external fixator after performing open reduction and internal fixation and evaluated the clinical outcome. Between 2005 and 2011, eleven patients with elbow ...
