INTRODUCTION: In general, the long head of the biceps brachii (LHB) tendon arises from the supraglenoid tubercle in the shoulder joint, and it has an important stabilizing mechanism for the humeral head in the shoulder joint. This case demonstrates that even if the LHB tendon can be palpated outside of the shoulder joint, it may disappear in the intertubercular sulcus (IS) and in the glenohumeral (GH) joint because of abnormal articulation. PATIENT CONCERNS: This case involved the cadaver of an 82-year-old Japanese man (number 1936, cause of death: hepatocellular tumor), who was selected from the bodies used for gross anatomy practice at the Tokai University School of Medicine in 2017...

Proximal humerus fracture is a common arm trauma and rarely occurs with vascular injury which however is a serious complication. In this case report, we present a long segment dissection of the axillary and brachial arteries as a rare complication due to fragmented proximal humerus fracture and shoulder dislocation. An 80-year old female patient was seen at the emergency department. Radiograph examination has revealed a fragmented proximal humerus fracture besides dislocation of the head of humerus towards the axillary area...

Humeral fractures typically occur as the result of direct, external trauma. Here however, we describe the case of a young, amateur athlete presenting with acute right, upper arm pain after throwing a ball. Examination showed right upper arm deformity and tenderness to palpation, without any distal neurovascular deficits. X-ray demonstrated a spiral fracture of the humerus. The patient had operative repair of the injury several days later, with no complications noted on outpatient visits up to 3 months later...

We report the case of a 46-year-old woman who struck her right elbow on the ground after a fall on ice. Radiography showed a right humeral capitellar fracture, and CT further confirmed a Dubberley type 1A fracture. Closed reduction was performed under local anaesthesia, and an anatomical position was obtained. After the reduction, her right elbow was casted for 18 days. Three months after the injury, bone union was achieved without displacement, and the active range of motion of her right elbow recovered similar to the unaffected side...

BACKGROUND: In computer-assisted reconstructive surgeries, the contralateral anatomy is established as the best available reconstruction template. However, existing intra-individual bilateral differences or a pathological, contralateral humerus may limit the applicability of the method. The aim of the study was to evaluate whether a statistical shape model (SSM) has the potential to predict accurately the pretraumatic anatomy of the humerus from the posttraumatic condition. METHODS: Three-dimensional (3D) triangular surface models were extracted from the computed tomographic data of 100 paired cadaveric humeri without a pathological condition...

Mark S Ayoub, Ivan S Tarkin
For younger patients with extra-articular distal humerus fractures closed management is plagued with high rates of malunion, suboptimal functional outcomes, extended immobilization with loss of early motion, a delay in return to work, and a general period of lost productivity. Surgical management offers an appealing alternative. Maintaining respect for the triceps musculature and minimizing iatrogenic injury to the radial nerve are primary concerns with operative treatment. Accordingly, use of a triceps-sparing approach and single column plating may be the optimal treatment paradigm in the young patient presenting with an extra-articular distal humerus fracture...

PURPOSE: Corticotomy is an integral part of the Ilizarov method on management of infected nonunited fractures that are challenging orthopaedic surgeons. However, the presence of active draining sinuses may contaminate the operative field with the potential of developing corticotomy site infection. The authors present a surgical technique aiming at minimizing or avoiding the risk of surgical site infection (SSI) in the corticotomy zone. PATIENTS AND METHODS: A total of 144 cases of draining infected nonunions were treated by Ilizarov fixator using the corticotomy-first technique...

BACKGROUND: Reverse shoulder arthroplasty (RSA) designs vary in the lateralization and distalization geometry, which may affect functional outcomes. The purpose was to determine the effect of RSA lateralization and distalization on final functional outcomes by using the "lateralization shoulder angle" (LSA) and the "distalization shoulder angle" (DSA). METHODS: Forty-six consecutive patients who underwent RSA for cuff tear arthropathy were retrospectively evaluated...

We report a case of a 29-year-old man who presented with a distal humeral shaft fracture sustained by blunt trauma. Physical examination and nerve conduction study were consistent with injury to the median and radial nerves proximal to the elbow. The patient underwent open reduction and internal fixation of the humeral shaft fracture with neurolysis of the median and radial nerves. Repeat electromyography at 6 months postoperatively showed recruitment of motor units in all muscles sampled, in keeping with clinical improvement...

Background: There is relatively little literature on elbow disease in the horse. The only published reports on soft tissue conditions describe collateral ligament and biceps brachii injuries. Case presentation: A three-year old Thoroughbred gelding presented with a history of acute onset right forelimb lameness of less than one week duration, one month after commencing training in a National Hunt racing yard. Physical examination and peri-neural anaesthesia failed to localise the lesion...

Background: The location of the ulnar styloid process can be confusing because the radius and the hand rotate around the ulna. The purpose of this study was to identify the absolute location of the ulnar styloid process, which is independent of forearm pronation or supination, to use it as a reference for neutral forearm rotation on lateral radiographs of the wrist. Methods: Computed tomography (CT) images of 23 forearms taken with elbow flexion of 70° to 90° were analyzed...

INTRODUCTION: Coronal plane distal humeral injuries are relatively rare. Numerous classification systems have been proposed as the complexity of these fractures has been realized. We in the present series of ten patients describe the surgical technique of Open Reduction and Internal Fixation of Coronal plane fractures of the distal humerus with headless compression screws performed using the anterolateral approach. MATERIAL AND METHOD: It was a retrospective study, the data collected from March 2010 to 2015 was analysed and the final outcome was assessed using the DASH score...

A 2-year-old cat was presented with the complaint of acute-onset non-weight-bearing lameness of the right forelimb. When examined, the cat was of short stature and had multiple joint and cartilaginous abnormalities suggestive of chondrodysplasia. The cause of the acute lameness was radiographically identified as a displaced osseous fragment from the medial portion of the right humeral condyle. The features of the osseous fragment were consistent with an ununited medial condylar ossification centre of the distal humerus...

Around one third of humeral fractures and 2-6% of all fractures occur to the distal part of the humerus. There is a bimodal distribution differentiating between young male patients with high-energy and elderly female patients with low-energy trauma related to osteoporosis. The AO classification and Dubberley subclassification are used in daily routine. Most fractures are diagnosed on radiographs. For further evaluation, three-dimensional computed tomography is recommended, especially for comminuted or complex fractures...

BACKGROUND: In adults, a relative "safe zone" for lateral approaches to the elbow has been well described in efforts to reduce iatrogenic injury, typically a minimum of 6 cm proximal to the lateral epicondyle. To avoid iatrogenic injury to the radial nerve intraoperatively, we investigated the distance of the nerve from the distal humeral physis in children. METHODS: All patients who had axial and coronal T1-weighted magnetic resonance imagings of the humerus and elbow between 2005 and 2015 were eligible...

BACKGROUND: Distal humerus physeal separations are rare pediatric elbow fractures that are often misdiagnosed and difficult to treat. Adequate reduction is often technically challenging and up to 71% of children develop postoperative cubitus varus. We propose using the medial and lateral humeral lines as an adjunct to elbow arthrography in order to guide intraoperative fixation of distal humerus physeal separations to reduce the incidence of postoperative cubitus varus. METHODS: From 2009 to 2014, all pediatric patients under the age of 3 diagnosed with a distal humerus physeal separation and treated surgically at our institution were included for analysis...
