BACKGROUND: Repair of distal biceps tendon ruptures has become widely accepted. Unfortunately, care of retracted-degenerated injuries remains a challenge for orthopedic surgeons. Complication rates appear to increase when surgery is performed in chronic cases compared to those operated acutely. Multiple techniques for chronic reconstruction with the use of grafts have been described. Recently Morrey, from the Mayo Clinic, proposed a direct anatomic repair of retracted distal biceps tendon ruptures in extreme flexion (60°-90°) to avoid grafting...

Fractures of the humerus shaft often are complicated by radial nerve palsy. Controversy still exists in the treatment that includes clinical observation and eventually late surgical exploration or early surgical exploration. Algorithms have been proposed to provide recommendations with regard to management of the injuries. However, advantages and disadvantages are associated with each of these algorithms. The aim of this study was to analyze the indications of each treatment options and facilitate the surgeon in choosing the conduct for each lesion, proposing our own algorithm...

Lateral humeral condyle fracture is the second most common fracture around the elbow in pediatric age group. Acute neurological deficit as a consequence of nerve injury associated with lateral humeral condyle fractures is very uncommon. We report a rare presentation of a case of lateral humeral condyle fracture in a 13-year-old boy with acute radial nerve palsy. Patient was operated through a modified anterolateral approach to the elbow with, exploration of the radial nerve and internal fixation of the fracture...

: In wrist arthroscopy, the standard dorsal portals are the most commonly used. However, their placement can be associated with injuries to the neurovascular structures of the radiocarpal joint. The present study assessed and compared the distance of commonly used dorsal portals to radial and ulnar neurovascular structures. Forty patients (20 males, 20 females) were evaluated with T1-weighted spin-echo (SE) magnetic resonance (MR) sequences. We measured the distance between 1-2 and 3-4 portals and radial vascular bundle and the nearest branch of the superficial branch of radial nerve (SBRN)...

BACKGROUND: Some leading anatomy texts state that all three heads of the triceps brachii are innervated by the radial nerve. The posterior cord of the brachial plexus bifurcates to terminate as the radial and axillary nerves. Studies have noted the presence of axillary innervation to the long head of the triceps brachii muscle, patterns different from the classic exclusive radial nerve supply. An understanding of these variations may assist the clinician in the assessment of shoulder weakness and in preoperative and operative planning of radial and axillary neuropathies...

PURPOSE: The purpose of this study was to investigate the early complications associated with the dorsal approach to the proximal radius. This approach, also called the Thompson approach, is used relatively infrequently for the treatment of forearm fractures. It is primarily reserved for proximal one-third radius fractures where a volar plate may not be placed sufficiently proximal for adequate fixation. METHODS: A retrospective chart review was performed on forearm fractures performed at our institution...

Background Scapholunate (SL) interosseus ligament injuries detected at an early stage could allow the surgeon to prevent progression through the spectrum of injury that leads to instability, and eventually osteoarthritis. We contend that early instability following injury can be detected by visualizing the relative motions and distances between the involved carpal bones (scaphoid and lunate) during wrist movement in vivo. The purpose of this study is to demonstrate the utility of dynamic CT (i.e., 4DCT) in diagnosing SL interosseus ligament injuries in two patients with clinical suspicion of SL interosseus ligament injury during flexion-extension (FE), radial-ulnar (RU) deviation, and dart thrower's (DT) motions...

Visual function has been shown to deteriorate prior to the onset of retinopathy in some diabetic patients and experimental animal models. This suggests the involvement of the brain's visual system in the early stages of diabetes. In this study, we tested this hypothesis by examining the integrity of the visual pathway in a diabetic rat model using in vivo multi-modal magnetic resonance imaging (MRI). Ten-week-old Sprague-Dawley rats were divided into an experimental diabetic group by intraperitoneal injection of 65 mg/kg streptozotocin in 0...

BACKGROUND: Evolving wrist arthroscopy requires creating new portals, and creating portals reciprocally leads to increased indications for arthroscopic wrist procedures. To facilitate access to the lunate bone and fossa for new arthroscopic procedures, a new portal was used. This is a cadaveric study of this portal. OBJECTIVES: In this cadaveric study, we evaluated a portal in wrist arthroscopy for procedures involving the lunate bone and lunate fossa. MATERIALS AND METHODS: Seventeen wrists from 10 fresh cadavers were included in this study...
