Osteochondral lesions (OCLs) that are frequently encountered in skeletally immature and adult patients are more common than once thought, and their incidence rate is rising. These lesions can appear in many synovial joints of the body, such as the shoulder, elbow, hip, and ankle, occurring most often in the knee. The term osteochondral lesion includes a vast spectrum of pathologies such as osteochondritis dissecans, osteochondral defects, osteochondral fractures, and osteonecrosis of the subchondral bone.

Isolated humeral trochlea fracture, particularly in skeletally immature children, is extremely rare. The exact mechanism of this injury remains unknown because the humeral trochlea is embraced within the olecranon fossa without any muscular or ligamentous attachment. We report the treatment of a 6-year-old boy who sustained an isolated trochlea osteochondral fracture when he fell with his elbow in a flexed position while skateboarding. Read More

Background: Fractures are the most common type of unintentional injury in children, with traumatic upper limb fractures accounting for approximately 80% of all childhood fractures. Many epidemiological investigations of upper limb fractures in children have been conducted, but with the development of society, the patterns of childhood fractures may have changed. This study aimed to analyze the epidemiology and economic cost factors of upper limb fractures in Chinese children. Read More

Background: Brachial plexus birth injuries (BPBIs) can often result in functional and cosmetic deficits including, according to a recent scoping review, elbow flexion contractures in up to 48%. A treatment algorithm that includes a custom long-arm orthosis to optimize early glenohumeral joint positioning (Sup-ER protocol) has been shown to improve shoulder range of motion. Although the protocol was not intentionally designed to affect the elbow, this study investigates the prevalence and severity of elbow flexion contractures in children treated with that protocol.

Introduction: This study investigated the anatomic feasibility of a new surgical therapy option for radial head arthrosis using an autologous vascularized bone graft of the second metatarsal and proximal fibula to recreate the proximal radiohumeral joint.

Materials And Methods: Upper and lower extremities of eleven body donors were evaluated using CT prior to anatomic dissection. Several distinct anatomic parameters were measured on the ipsi- and contralateral radial and fibular head and the second metatarsal base: bone diameter, articular surface diameter, head height, metaphyseal (neck) diameter, articular surface radius, total articular surface area, and angulation of the articular surfaces (facet).

Purpose: The purposes of this in vitro study were to investigate whether the addition of dexamethasone can compensate for any cytotoxic effects of the amide-type local anesthetics (LA) bupivacaine and ropivacaine and whether morphine and morphine-6-glucuronide (M6G) may be a safe alternative for peritendinous application.

Methods: Biopsies of human biceps tendons ( = 6) were dissected and cultivated. Cells were characterized by the expression for tenocyte markers, collagen I, biglycan, tenascin C, scleraxis, and RUNX via reverse transcriptase-polymerase chain reaction and immunohistochemistry. Read More

Continuous peripheral nerve block, also known as "local anesthetic perineural infusion," refers to percutaneous placement of a catheter near a peripheral nerve or plexus followed by administration of a local anesthetic through a catheter to provide anesthesia, or analgesia for several days, in some cases even for a month. This report describes the case of a 7 year old boy with left elbow contracture with limited flexion and extension who was admitted to the Clinic of Pediatric Surgery for redressment of the elbow and physical therapy. An ultrasound-guided axillary brachial plexus block was performed, with placement of a non-tunneled perineural catheter. Read More

Subcutaneous emphysema is commonly associated with infection caused by gas-producing organisms. In this case report, we describe a rare instance of traumatic subcutaneous emphysema of the hand and forearm caused by a puncture injury to the first web space of the hand. Our objective is to increase awareness of the potential for seemingly minor trauma to cause entrapment of significant air in subcutaneous tissues, thereby decreasing the likelihood that a clinically benign-appearing patient will be started down an unnecessarily aggressive treatment pathway.

Background: Pediatric supracondylar humerus fractures (pSCHFs) may be challenging injuries to treat because of the potential residual deformity. There is debate regarding the technical aspects of adequate closed reduction and crossed Kirschner wire (K-wire) fixation.

Purpose: Do surgeons have an agreement on the aspects of the fixation of pSCHFs?

Methods: Radiographs of 20 patients from a cohort of 154 patients with pSCHFs treated with closed reduction and crossed K-wire fixation were selected. Read More

Department of Orthopedic Surgery, William Beaumont Hospital, Royal Oak, Michigan.

Introduction: Monteggia fracture-dislocations are rare and complex injuries that usually involve a fracture of the proximal ulna associated with a proximal radioulnar and radiocapitellar joint dislocations. These injuries comprise <1% of all pediatric forearm fractures. We report on a pediatric Monteggia fracture-dislocation variant that included an irreducible divergent ulnohumeral joint dislocation, an irreducible anterior radial head dislocation, and a proximal and distal radius and ulna fracture.

We evaluated the functional and radiological outcomes of surgically treated supracondylar humerus fractures based on injury mechanisms, as well as the therapeutic and prognostic aspects of monkey bar-related injuries, in this study. Between December 2014 and December 2018, pediatric patients who had undergone surgical treatment for supracondylar humerus fractures were analyzed retrospectively. According to the mechanism of injury, patients were divided into two groups: monkey bar-related injuries and other injuries. Read More

Department of Pharmacology, Vanderbilt University.

Background: Nonaccidental trauma (NAT) is a rising source of morbidity and mortality in the pediatric population. Fractures are often the first cause for presentation to health care providers in the case of NAT but can be misidentified as accidental. Given that elbow fractures are the most common accidental injuries among pediatric patients, they are not traditionally associated with NAT. Read More
