Kristopher B McCall, David Y Chong
A pediatric patient presenting with an open forearm fracture with segmental defect is rare, and the pediatric orthopedic literature to guide treatment is sparse. There are several described methods to treat the defect, including bone grafting and bone transport techniques. In addition, there are reports of fibular regeneration after resection if the periosteum is left intact. We present a case report of complete regeneration of over half of a pediatric radial shaft with an intact periosteum, after traumatic extrusion from an open fracture...

Musculoskeletal (MSK) conditions are the most common cause of severe long-term pain and physical disability. Current postoperative treatment for patients requires them to follow a long-term physiotherapy program customized for each specific case; however, this process can be complex, time-consuming and without the right therapy it may end up being ineffective. A possible solution involves the development of wearable mechatronic elbow braces that use electromyography (EMG) to identify patient intent. However, EMG characteristics change based on the health of the individual and therefore require further investigation...

Rehabilitation exoskeletons may make use of myoelectric control to restore in patients with significant motor impairment following a spinal cord injury (SCI) a sense of volitional control over their limb - a crucial component for recovery of movement. Little investigation has been done into the feasibility of using surface electromyography (sEMG) as an exoskeleton control interface for SCI patients, whose impairment manifests in a highly variable way across the patient population. We have demonstrated that by using only a small subset of features extracted from eight bipolar electrodes recording on the upper arm and forearm muscles, we can achieve high predictive accuracy for the intended direction of motion...

Isolated coronal shear fracture of the trochlea is a rare injury. Isolated fractures of the humeral trochlea have all been reported in adults. We present the case of a 7-year-old boy with pain and swelling of the elbow joint. Magnetic resonance imaging and arthrogram revealed an isolated osteochondral fracture of the trochlea in the coronal plane. Ossification of the trochlea had not yet occurred. An anterior approach was used for reduction and fixation of the fragment. A good clinical outcome was achieved with no signs of bony or chondral necrosis of the fragment 1 year after surgery...

BACKGROUND: Pathologies of the long head of biceps tendon (LHB) can cause anterior shoulder pain. Surgical treatment includes tenotomy and tenodesis (TD), however TD causes fewer cosmetic deformities and less cramping of the biceps muscle. To date, numerous techniques for TD have been described but the "gold standard" has not yet been established. OBJECTIVES: The purpose of this study is to evaluate the functional and cosmetic outcome following subpectoral biceps TD with an interference screw and a cortical-button (STLHB-IC) after 1 year...

BACKGROUND: Likely due to the high level of strain exerted across the elbow during the throwing motion, elbow injuries are on the rise in baseball. To identify at-risk athletes and guide postinjury return-to-throw programs, a better understanding of the variables that influence elbow varus torque is desired. PURPOSE: To describe the within-subject relationship between elbow varus torque and arm slot and arm rotation in professional baseball pitchers. STUDY DESIGN: Descriptive laboratory study...

BACKGROUND AND OBJECTIVE: Playing string instruments requires advanced motor skills and a long training that is often spent in uncomfortable postures that may lead to injuries or musculoskeletal disorders. Thus, it is interesting to objectively characterize the motor strategy adopted by the players. In this work, we implemented a method for the quantitative analysis of the motor performance of a violin player. METHODS: The proposed protocol takes advantage of an optoelectronic system and some infra-red reflecting markers in order to track player's motion...

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 affected arm. Pulled elbow is usually treated by manual reduction of the subluxed radial head...

Jeremy sustained bilateral complete brachial plexus injuries in an auto collision on an icy road a month before his third birthday. The accident rendered both upper extremities completely flail and insensate: he has no motor or sensory function of his shoulders, elbows, wrists, or digits. Jeremy does, however, have normal function of the lower extremities. Physical therapists have worked with the child for over a year with no noted improvement in arm function. Jeremy falls frequently, causing injury to his face and head, and occasionally, his arms get twisted or caught in his crib and his fingers turn blue...

This case is described of an eleven-month-old infant with lower limbs swelling and the left elbow skeletal malformation following a fall. The radionuclide bone scan was performed to exclude bone infection or congenital skeletal anomaly. The images unexpectedly showed multiple increased radioactive foci throughout the whole body. It was a strong probability of child abuse. All lesions are readily apparent on the following plain film radiographs and MRI.
