A sac-like protrusion on the right upper arm

Indirect BP measurement was obtained in the right upper arm in 219 healthy newborn infants with the Dinamap monitor and was compared with values obtained from the calf to establish normative BP values and to help establish a diagnosis of hypertension and coarctation of the aorta in the newborn. There were 174 Mexican-Americans (79.5%), 33 whites (15.0%), and 12 blacks (5.5%). The width of the BP cuff was selected to be 0.4 to 0.5 times the circumference of the extremities. Three supine position readings of BPs and heart rate were obtained from each site and were averaged for statistical analyses. Mean arm BP values (±SD) of the neonate less than 36 hours of age were 62.6±6.9/38.9± 5.7 mm Hg (48.0±6.2 mm Hg). Neonates older than 36 hours had slightly but significantly (P<.05) greater values (4 to 6 mm Hg) than did infants younger than 36 hours of age. Active neonates had values 6 to 10 mm Hg greater than quiet neonates (P<.05). BP values in the calf obtained with the same-sized cuff were almost identical with those obtained from the arm. Differences in consecutively obtained arm and calf BPs (arm values minus calf values) were 1.1±7.7 mm Hg systolic, -0.01 ± 6.2 mm Hg diastolic, and 0.9 ±6.9 mm Hg mean pressures. Mean heart rate (±SD) of neonates less than 36 hours of age was 129.4± 13.2 beats per minute and that of neonates older than 36 hours of age was 139.4± 14.1 beats per minute. These results show the following: (1) arm BPs and calf BPs using the same-sized cuff are almost identical with mean values of approximately 65/ 41 mm Hg (50 mm Hg) in neonates one to three days of age, (2) arm BP of 75/49 mm Hg (59 mm Hg) or greater is in the hypertensive range, and (3) calf BPs that are less than arm BPs by mean + 1 SD (6 to 9 mm Hg) necessitate a thorough investigation for coarctation of the aorta.

The Relationship

The purposes of this study were to examine the consistency of wheelchair athletes’ upper-limb kinematics in consecutive propulsive cycles and to investigate the relationship between the maximum angular velocities of the upper arm and forearm and the consistency of the upper-limb kinematical pattern. Eleven elite international wheelchair racers propelled their own chairs on a roller while performing maximum speeds during wheelchair propulsion. A Qualisys motion analysis system was used to film the wheelchair propulsive cycles. Six reflective markers placed on the right shoulder, elbow, wrist joints, metacarpal, wheel axis, and wheel were automatically digitized. The deviations in cycle time, upper-arm and forearm angles, and angular velocities among these propulsive cycles were analyzed. The results demonstrated that in the consecutive cycles of wheelchair propulsion the increased maximum angular velocity may lead to increased variability in the upper-limb angular kinematics. It is speculated that this increased variability may be important for the distribution of load on different upper-extremity muscles to avoid the fatigue during wheelchair racing.

In 1856 the coffin of Princess Elizabeth (1635-1650) was discovered during the demolition of old St. Thomas's Church at Newport, Isle of Wight, England. Mr. Ernest P. Wilkins, MRCS, examined the remains of the Princess and noted:1 The bones of the upper arm were slightly curved outwards—more particularly the right humerous—while those of the forearm were somewhat twisted and considerably curved outwards. The spinal column, retaining the relative position of the vertebrae during life, presented an extremely curved condition constituting the double lateral or S curvature of pathologists, which must have caused considerable projection of the right shoulder-blade and its attendant deformity .... The condyles of the lower extremities were very large in relative proportion. The femur or thigh bone of the left side was curved forwards and inwards, that of the right side was more distorted than any other long bone. It was very much curved forwards and inwards. This bone was much flattened, its greatest diameter being from before, obliquely outwards and backwards; the concavity of the curve was somewhat filled in, and the bone thus strengthened by additional osseous deposit in accordance with the natural reparative tendency of Nature's laws. The bones of the leg, the tibia and fibula, were much curved outwards. The bones of the skeleton indicate the great deformity which existed during life—there was evidently considerable "growing out" of the right shoulder-blade and corresponding flattening of the left side of the back. The lower extremities were contorted and of unequal length, the knees were what is termed "knocked"; below the knees the legs were bowed, the heels thrown outwards and the toes inverted.

This controlled, exploratory laboratory study was conducted to measure hand-arm vibration (HAV) exposures when using a bucking bar fitted with three different handles: 1) a typical plastic handle, 2) a similarly designed handle with an aluminum core and a built-in dampening spring, and 3) a steel core handle with the same built-in spring. Using two experienced machinists, tri-axial HAV exposures were measured at the bucking bar handles; small, battery-powered, self-contained Inertial Measurement Units (IMUs) were used to measure the vibration transmitted through the tool operator’s left and right arms; and a wearable device worn on the operator’s right wrist estimated the HAV exposures occurring at the tool handle. The plastic handle produced the highest HAV exposures while the aluminum-spring and steel spring handles reduced exposures by 19% and 39%, respectively. On average, 74%, 65% and 40% of the tool-measured vibration was transmitted to the right hand, forearm and upper arm, respectively. The wrist mounted sensor appeared to accurately estimate HAV exposures measured at the hand-tool interface.

Objective: To evaluate relative and absolute reliability and repeatability in assessing median nerve mobility at the level of the wrist and distal upper arm of the right upper extremity during wrist extension. Methods: Six healthy participants participated in the study. Median nerve mobility was captured three times at both sites using Sonocyte Turbo by two sonologists for a total of 72 video clips (36 for each site and 18 by each sonologist). Longitudinal movement was measured using Motion Tracking Analysis Program (MTAP) by the two assessors who were rehabilitation medicine residents. After one month, the assessors remeasured the longitudinal excursion of the median nerve of the previous video clips. Results: There was moderate agreement between the two sonologists of the median nerve mobility at the level of the distal upper arm and the wrist respectively. There was a moderate to almost perfect agreement between the two assessors’ readings in the mobility of the nerve at level of the distal upper arm and wrist for the first and second readings. Repeatability testing showed that there was variable agreement at the level of the distal upper arm and at the wrist. Conclusion: MTAP using fast template tracking with an adaptive template is a reliable tool that can be employed in the accurate assessment of median nerve mobility at the distal upper arm and wrist.

The aim of the study was to determine whether maintaining the standing balance position is influenced by athlete’s symmetric morphological characteristics. Thirty-two healthy sports students participated in this study (age 19.8±1.4 years, body height 182.9±6.8 cm, body weight 79.1±8.1 kg). Morphological characteristics are represented with differences between the left and the right body side of: forearm girth, upper arm girth, calf girth, thigh girth, long shoulder height, lean mass of legs and lean mass of arms. The standing balance result was calculated as a result of factor scores for 9 measurements of 30 seconds (3 measurements of normal standing, 3 measurements of blind standing, and 3 measurements of deaf standing) collected from the pressure insoles system and the difference in ground reaction force between the left and the right leg. Results show that the asymmetric leg load in maintaining standing balance depends on the side differences in the thigh girth and upper arm girth. The greater difference in the thigh girth in favour of the left side resulted in bigger ground reaction force on the right leg compared to the left leg and the greater difference in the upper arm girth in favour of the left side resulted in bigger ground reaction force on the left leg. To avoid one side overload, it is essential for all sports activities to be performed bilaterally.

Extensor Carpi Radialis

ABSTRACTRadial nerve is usually a branch of the posterior cord of the brachial plexus. It innervates triceps, anconeous, brachialis, brachioradialis, extensor carpi radialis longus muscles and gives the posterior cutaneous nerve of the arm, lower lateral cutaneous nerve of arm, posterior cutaneous nerve of forearm; without exhibiting any communication with the medial cutaneous nerve of forearm or any other nerve. We report communication between the radial nerve and medial cutaneous nerve of forearm on the left side in a 58-year-old male cadaver. The right sided structures were found to be normal. Neurosurgeons should keep such variations in mind while performing the surgeries of axilla and upper arm.

Abstract Background Acute compartment syndrome (ACS) is a potentially devastating condition. ACS is rare in the upper arm. Case presentation We report a case of acute compartment syndrome of the anterior compartment of the upper arm due to brachial muscle injury. The patient experienced abnormal progressive swelling and pain in his right upper arm, and passive pulling pain of the right wrist and right hand. It was highly suspected to be right upper arm compartment syndrome, and was confirmed by surgery. The patient transferred to the emergency operating room for fasciotomy that was performed under general anesthesia using the anterolateral approach. The brachial muscle was found to be heavily swollen and had the greatest tension. The brachial muscle fibers were split lengthwise, and a large amount of hematoma was cleared. The brachial muscles were injured and partly ruptured. After full decompression, a negative pressure drainage device was used to cover the wound in the first stage. Ten days after injury, the swelling of the affected limb subsided and the wound was sutured. The patient’s limbs completely recovered to normal. The shoulder and elbow joints could move freely and the patient resumed normal farming work ability. Conclusion Clinicians should fully recognize the fact that acute compartment syndrome can occur in the upper arm, rather than only the forearm and leg, and therefore avoid serious consequences caused by missed diagnosis and misdiagnosis.
