We previously reported that elbow magnetic resonance imaging (MRI) with 7 kg traction increases the joint space width of the radiocapitellar joint and improves articular cartilage visibility without arthrography. However, the optimal traction weight remains unclear. We assessed the effects of different traction weights on elbow MRI in 30 healthy volunteers. Elbow MRI was performed without traction and with 3, 5, and 7 kg axial tractions. The joint space width, humeral articular cartilage outline visibility, and intraprocedural pain/discomfort were evaluated...

BACKGROUND: Medial ulnar collateral ligament (mUCL) injury can cause significant pain and alter throwing mechanics. Common autograft options for mUCL reconstruction (UCLR) include the palmaris longus (PL) and hamstring tendons. Allograft use may reduce donor site morbidity and decrease function related to PL autografts. PURPOSE: To compare varus stability and load to failure between a novel allograft for UCLR-knee medial collateral ligament (kMCL)-and a PL autograft in human donor elbow specimens...

Hemimelia denotes the partial or complete absence of the distal half of a limb. Ulna hemimelia, a rare congenital anomaly, involves the complete or partial absence of the ulna in the upper limb, with an incidence of 1 in 150,000. This condition has been classified into 4 types, with the rare Type 4 variant involving humeroradial synostosis. We present a unique case of bilateral complete ulna hemimelia, humeroradial synostosis, and oligodactyly, in an 11-month-old female with bilateral upper limb shortening and restricted elbow movement since birth...

Intra-articular distal humerus fractures present various challenges with a wide array of treatment options. Open reduction internal fixation remains the treatment of choice. In older patient populations with poor bone quality and short-end segment fractures with articular comminution, open reduction internal fixation, however, may bring on unsurmountable technical challenges. Total elbow arthroplasty and elbow hemiarthroplasty (EHA) may offer superior functional outcomes in these cases. During EHA for fractures, the medial and lateral columns are reconstructed with the collateral ligaments to restore elbow stability...

OBJECTIVES: Bankart lesion is one of the most common lesions of the glenohumeral joint. Several double-row suture methods were reported for Bankart repair, which could provide more stability, yet more motion limitation and complications. Therefore, we introduced a new double-row Bankart repair technique, key point double-row suture which used one anchor in the medial line. The purpose of this article is to investigate the clinical outcomes of this new method and to compare it with single-row suture...

Radial nerve entrapment is an uncommon diagnosis. The entrapment can occur at any location within the course of the nerve distribution, but the most frequent location of entrapment occurs around the elbow and involves the posterior interosseous nerve. Several potential sites of radial nerve entrapment around the elbow are identified: the capsular tissue of the radiocapitellar joint; hypertrophic crossing branches of leash of henry; the leading proximal tendinous and medial edge of ECRB; the arcade of Frohse and distal border of the supinator between its two heads...

Snapping triceps syndrome is a rare cause of medial elbow pain and ulnar neuritis caused by subluxation and triggering of the medial tricipital muscle belly over the medial distal humeral ridge and condyle. The diagnosis and surgical management of snapping triceps syndrome can be challenging due to the subtlety of the symptoms and the infrequent presentation. Despite the diagnosis relying largely on clinical examination, noninvasive dynamic ultrasonography may facilitate detection. Correct recognition of this condition is crucial in the avoidance of surgical misadventure and revision surgery...
