During the fifth century BC in ancient Greece during the eve of orthopaedics, the Hippocratic School of Medicine diagnosed a series of congenital limb deformities. Congenital dislocation of the arm, elbow, wrist, hip, knee, tarsotibial joint, apex leg, as well as talipes valgus (clubfoot), congenital clavicle fractures, and thumb malfunction were all discussed by Hippocrates and his followers. Ancient Greek medico-philosophers, fond of a "perfect" human body, proposed an immediate non-interventional approach, while archaic orthotics and specialized footwear were suggested. Read More

Sporthopaedicum, Straubing and Regensburg, Bahnhofplatz, 27, 94315, Straubing, Germany.

Purpose: Most elbow dislocations can be treated conservatively, with surgery indicated in special circumstances. Surgical options, apart from fracture fixation, range from repair or reconstruction of the damaged ligaments to static external fixation, usually entailing either a long period of immobilization followed by carefully monitored initiation of movement or dynamic external fixation. In general, no consensus regarding surgical treatment has been reached. Read More

Department of Orthopaedic Surgery and Traumatology, Inselspital, University of Bern, Inselspital, Freiburgstrasse, Bern, Switzerland.

Introduction: The purpose of this proof-of-concept study was to investigate the biomechanical performance of two surgical techniques, namely (1) the double Tight-Rope fixation with an additional acromioclavicular FiberTape fixation (DTRC) and (2) the fixation of the clavicle to the acromion and coracoid in a bipodal manner (Bipod) using a Poly-Tape and FiberTape. Both techniques intend to address vertical and horizontal instability after acromioclavicular dislocation. They were compared with the commonly used (3) double Tight-Rope (DTR) technique, which only stabilizes the clavicle to the coracoid. Read More

Purpose: Current options for treating elbow instability include bony and/or ligamentous fixation with orthosis or cast immobilization, transarticular cross-pinning, temporary bridge plating, and hinged or rigid external fixation. Our purpose was to evaluate the recently developed internal joint stabilizer (IJS), which acts as an internal external fixator of the elbow. Our primary end point was to assess whether use of the device results in a stable and congruent reduction of the ulnohumeral and radiocapitellar joints in patients with acute or chronic elbow instability as a result of trauma.

Terrible triad injury of the elbow is a complex injury that is classically defined as elbow dislocation along with fractures of the coronoid process of the ulna and the radial head. The injury is usually associated with typical soft-tissue disruptions (with common involvement of the lateral collateral ligament complex, elbow joint capsule, as well as the common extensor and flexor-pronator tendons) that are best understood in the context of injury mechanism as well as the role and relevance of the various elbow stabilizers. The goals of this article are to review the pertinent anatomy, mechanism of injury, classification and imaging of terrible triad injuries of the elbow with brief descriptions of treatment, and complications of this complex injury.

Department of Orthopaedic Surgery, MetroHealth Medical Center, Case Western Reserve University School of Medicine, Cleveland, Ohio.

Case: A 30-month-old boy with a displaced medial condyle fracture and no history of an elbow dislocation was found to have an entrapped median nerve.

Conclusion: Entrapment of the median nerve is a potential consequence of a displaced medial condyle fracture, even when there are no neurologic deficits on presentation. This provides additional support for open reduction of these fractures rather than percutaneous treatment or nonoperative management. Read More

Chirurgie orthopédique et traumatologique, CHU Charles-Nicolle, 1, rue de Germont, 76031 Rouen, France.

The appropriate management of early treatment failures in patients with elbow injuries requires the identification of the cause of failure. In this work, six types of elbow injury are considered: (i) identification of early failed reduction of a dislocation or fracture-dislocation of the elbow should lead to a repeat reduction procedure, testing for elbow instability, and ligament repair, followed by the use of a hinged external fixator to allow early mobilisation. Differentiating an isolated dislocation from a dislocation combined with a fracture of the coracoid process is crucial. Read More

Department of Orthopaedic Surgery, New York-Presbyterian Hospital, New York, USA.

"Floating elbow" injuries of the arm traditionally represent a combination of humeral shaft and forearm fractures which require anatomic rigid open reduction and internal fixation of all fractures to allow for early range of motion exercises of the elbow. There are published variants of the floating elbow injury which include ipsilateral diaphyseal humeral fracture, proximal ulna fracture with proximal radioulnar joint disruption, and ipsilateral diaphyseal humeral fracture with elbow dislocation and both bones forearm fracture. We present the case of a 21-year-old woman whose left arm became caught between the side of a waterslide and adjacent rocks at a park. Read More

Purpose Of Review: The chronic Monteggia may lead to pain, mobility limitation, progressive valgus deformity, lateral elbow instability, late ulnar nerve paralysis, and degenerative changes. In this review, we discuss the current procedures in the literature focused on correcting chronic Monteggia to avoid these complications.

Recent Findings: Correction of the ulnar deformity with elongation and angulation of the ulna in the opposite direction of the dislocation of the radial head is the most important factor for the reduction and consequent preservation of the radial head. Read More

Nail-patella syndrome (NPS) or hereditary onycho-osteodyaplasia is a rare genetic condition involving a mutation in the LMX1B gene affecting nails, elbows, knees, and pelvis. Due to the regulatory functions of the gene in many developmental processes through the body, patients with NPS experience wide-ranging musculoskeletal problems including patellar instability, fingernail anomalies, iliac exostoses/horns, and elbow abnormalities. The patellar changes often involve aplasia, hypoplasia, and chronic dislocation. Read More

Western Orthopaedics, Denver, Colorado.

Case: A 49-year-old right-hand-dominant man sustained an auger-related injury that resulted in open dislocation at the left wrist and palm, with complete amputation of the distal aspect of the forearm and the hand. The injury at the elbow included instability with an ulnar coronoid fracture, posterior dislocation of the ulna, and posterolateral dislocation of the radius. To restore stability of the forearm stump and elbow, we performed a complete resection of the radius, open reduction and internal fixation of the coronoid tip, a repair of the lateral collateral ligament, and transfer of the distal biceps tendon to the coronoid.
