Medial epicondyle

Derrick M Knapik, Cameron L Fausett, Allison Gilmore, Raymond W Liu
BACKGROUND: Medial epicondyle fractures may occur in isolation or with associated elbow dislocation. In the absence of open fracture or fragment incarceration, nonoperative management with immobilization has been shown to result in generally successfully outcomes comparable with those reported after surgical fixation. However, no comparative investigation has assessed outcomes after nonoperative treatment based on the presence or absence of elbow dislocation. METHODS: A systematic review was conducted investigating all studies in the literature reporting nonoperative outcomes for isolated medial epicondyle fractures and fracture-dislocations...

INTRODUCTION: Among the various elbow injuries in children that initially have normal radiographs, a certain number of occult fractures are only diagnosed correctly after the fact, during a follow-up visit. PURPOSE: This study evaluated the diagnostic contribution of ultrasonography in the treatment of acute elbow injuries in children and the strategic and economic impact of using this tool alongside radiography. MATERIALS AND METHODS: During this prospective study performed between January 1 and April 1 2014, elbow ultrasonography was performed within 6 days in all children under 15 years of age with a suspected occult fracture...

BACKGROUND: Fasciocutaneous flaps supplied by discrete perforator arteries can be raised in numerous parts of the human body and are routinely used in plastic surgery. The aim of this anatomical investigation was to provide a description of the vascular supply of the medial upper arm, to localize and measure the perforator arteries and to define potential perforator flap dimensions in pendency of individual anatomical conditions. MATERIAL AND METHODS: A total of 20 upper limbs from 11 fresh cadavers were examined...

PURPOSE: The medial patellofemoral ligament (MPFL) is the major medial soft-tissue stabiliser of the patella, originating from the medial femoral condyle and inserting onto the medial patella. The exact position reported in the literature varies. Understanding the true anatomical origin and insertion of the MPFL is critical to successful reconstruction. The purpose of this systematic review was to determine these locations. METHODS: A systematic search of published (AMED, CINAHL, MEDLINE, EMBASE, PubMed and Cochrane Library) and unpublished literature databases was conducted from their inception to the 3 February 2016...

Chondroepitrochlearis (CET) is an anomalous muscular slip that originates from the pectoralis major muscle and inserts into epicondyle of the humerus. The morphology of this variant form of pectoralis major can vary from slender to strong musculo-tendinous. In its course, it usually crosses the neurovascular structures of arm; their compression is a major complication that could be manifested by its persistence. In the present case, potentially anomalous CET muscle with the slender slip of origin, but strong tendinous insertion to the medial epicondyle of the humerus was found unilaterally...

The aim of this study was to evaluate the rate of power Doppler ultrasound (PDUS) abnormalities at entheseal sites in patients with early psoriatic arthritis (PsA) naïve to traditional and biologic DMARDs and to compare the PDUS findings with clinical examination. PsA patients with early disease and naïve to traditional and biologic DMARDs were consecutively enrolled in this study. Patients underwent PDUS examination of the following bilateral entheseal sites: common extensor tendon at its insertion at the lateral humeral epicondyle; quadriceps tendon at its insertion at the superior pole of the patella; patellar tendon at its insertion at the tibial tuberosity; medial collateral ligament at its proximal insertion and Achilles tendon at its insertion at the calcaneus...

Brachialis periosteal avulsion injury is an uncommon injury occurring in young children. The injury may be misinterpreted or overlooked because of misleading or subtle radiological findings. A case of 7-year-old child with post-traumatic elbow pain and subtle findings on elbow radiography is presented. The injury was initially misinterpreted as an avulsion fracture of the medial epicondyle. Following radiological review, a diagnosis of brachialis periosteal avulsion injury was made. The radiographic and magnetic resonance imaging (MRI) findings of this injury are presented to stress the value of comparing the radiographic findings with previous imaging and to increase awareness of this uncommon injury...

BACKGROUND: The location of patellar and femoral fixation of the graft in medial patellofemoral ligament reconstructions has been widely discussed. This study aimed to assess the distances between different patellar and femoral fixation points to identify the least anisometric pairs of points. METHODS: Ten cadaver knees were attached to an apparatus that simulated an active range of motion of 120°, with three metallic markers fixed onto the medial side of the patella, and seven markings onto the medial epicondyle...

BACKGROUND: Angiofibroblastic changes of a musculotendinous origin at the medial epicondyle characterize medial epicondylitis of the elbow. Although nonsurgical treatment is the primary approach for medial epicondylitis, surgical treatment should be considered when conservative therapy fails. This study reports the results of surgical treatment of medial epicondylitis monitored for more than 5 years. METHODS: This study included 55 patients with 63 cases of medial epicondylitis between 2000 and 2010...

Fracture of the humeral medial epicondyle is a relatively common injury in children. Surgery is a good option for treatment, but correct diagnosis is important. Most fractures occur after the ossification of the medial epicondylar apophysis. If a fracture occurs before the ossification of the medial epicondyle, it is undetectable by radiographs. Here we report a case of an unossified medial epicondyle fracture of the humerus. A 9-year-old boy had persistent pain in the medial side of the right elbow after a fall...

Ulnar neuropathy at the elbow is the second most frequent entrapment neuropathy and is considered idiopathic in most patients. However, several anatomic variations, including the anconeus epitrochlearis muscle, have been reported to cause ulnar nerve compression. The anconeus epitrochlearis muscle is a common anatomic variation, with a prevalence of up to 34%, but the clinical diagnosis of ulnar neuropathy of the elbow as a result of this variation is rare, with an unknown prevalence. It is a congenital accessory muscle between the medial humeral epicondyle and the olecranon that covers the posterior aspect of the cubital tunnel and is usually an operative finding, not a preoperative diagnosis...

PURPOSE: Long-term functional results remain equivocal between operative fixation and closed management of displaced humeral medial epicondyle fractures. The purpose of this study was to determine whether a functional difference exists between treatment types. METHODS: One hundred and forty patients with a displaced medial epicondyle fracture between 2007 and 2014 met the inclusion criteria. Of this large cohort, only 12 patients agreed to return to clinic at a mean follow-up of 3 years for prospective evaluation...

An occupational illness is an event or exposure that occurs in the workplace that causes or contributes to a condition or worsens a preexisting condition. If an occupational disorder is suspected, a directed history should be taken with particular attention to establishing a temporal relationship of symptoms and exposure at work. Occupational asthma is the most prevalent occupational lung disorder in industrialized countries and presents with classic asthma symptoms (cough, difficulty breathing, chest tightness, wheezing)...

Ulnar neuropathy is caused by compression of the ulnar nerve in the upper extremity, frequently occurring at the level of the elbow or wrist. Rarely, ulnar nerve entrapment may be seen proximal to the elbow. This report details a case of ulnar neuropathy diagnosed and localized to the arcade of Struthers with electromyography (EMG) and ultrasound (US) imaging and confirmed at time of operative release. US imaging and EMG findings were used to preoperatively localize the level of compression in a patient presenting with left ulnar neuropathy...

INTRODUCTION: The aim of this study was to clarify the morphological characteristics of the intermuscular aponeurosis between the flexor carpi ulnaris (FCU) and flexor digitorum superficialis (FDS; IMAS), and that between the FCU and flexor digitorum profundus (FDP; IMAP), and their topographic relationships with the ulnar nerve. MATERIALS AND METHODS: Fifty limbs of 38 adult cadavers were studied. RESULTS: The IMAS extended along the deep surface of the FCU adjoining the FDS, having the appearance of a ladder, giving off "steps" that decreased in width from superficial to deep around the middle of the forearm...
