BACKGROUND: Extension deformity of the distal humerus after a malunited supracondylar fracture can restrict elbow flexion. Here we report a computer-assisted operative procedure and review the results of clinical cases in which corrective surgery was performed. METHODS: The medical records of the patients who underwent corrective osteotomy for hyperextended elbow malunion of the distal humerus with limited elbow flexion (flexion angle ≤100°) were reviewed retrospectively...

BACKGROUND: Metaphyseal-diaphyseal junction (MDJ) fractures of the distal humerus are problematic to reduce and more susceptible to post-operative complications. This biomechanical study was designed to compare Kirschner wires (KW), lateral external fixation, and elastic stable intramedullary nails (ESIN) in simulated transverse MDJ fractures of various heights. METHOD: Sagittally oblique, transverse MDJ fractures were created in fourth-generation composite bone models at three levels: high, mid, and low fractures, respectively, and then fixed with either Kirschner wires, lateral external fixation (EF), or ESIN respectively and tested in extension, flexion, valgus, varus, internal, and external rotations...

A 5-year-old female spayed Shetland sheepdog presented for evaluation of bandage sores on the left pelvic limb after a splint was placed to stabilise a digit fracture incurred approximately 2 weeks previously. Multiple areas of necrosis were identified upon bandage removal. After debridement of devitalised tissue, a 4 cm wound on the plantar surface of the metatarsal bones (with exposed bone and tendons) remained. The Papineau technique (which involves removal of infected or necrotic tissue, placement of autogenous cancellous bone graft within a wound, and delayed skin closure) was used to treat this wound...

The high rate of fixation failure in osteoporotic proximal humerus fractures indicate the need for improved solutions. Computer simulations may help to overcome the limitations of the gold standard biomechanical testing in evaluating the performance of new implants and enhance the effectivity and outcome of the design process. This study presents a framework for automated computational analysis that facilitates efficient and systematic evaluation of proximal humerus fracture plating under a variety of conditions including bone quality, fracture pattern, implant configuration and loading regime...

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...

Traumatic shoulder pain is pain directly attributed to a traumatic event, either acute or chronic. This pain may be the result of either fracture (the clavicle, scapula, or proximal humerus) or soft-tissue injury (most commonly of the rotator cuff, acromioclavicular ligaments, or labroligamentous complex). Imaging assessment of traumatic shoulder pain begins with conventional radiography and, depending on physical examination findings, will require MRI or MR arthrography for assessment of soft-tissue injuries and CT for delineation of fracture planes...

Fracture of lateral condyle with dislocation of the elbow joint is rare in pediatric age. Diagnosis and management of these injuries could be a challenge. Delayed presentation of such injuries could be mistaken for a malunited supracondylar fracture of the humerus and treatment of these injuries remains controversial. We present 2 such cases, where the diagnosis of dislocation of elbow was missed at initial presentation and caused diagnostic confusion at late presentation. The problems faced in the diagnosis of these injuries and the management of late presenting cases are discussed...

The objective of this study is to determine the reproducibility and feasibility of using 3-dimensional (3-D) computer simulation of proximal humerus fracture computed tomography (CT) scans for fracture reduction. We hypothesized that anatomic reconstruction with 3-D models would be anatomically accurate and reproducible. Preoperative CT scans of 28 patients with 3- and 4-part (AO classification 11-B1, 11-B2, 11-C1, 11-C2) proximal humerus fractures who were treated by hemiarthroplasty were converted into 3-D computer models...

The Gartland classification of pediatric supracondylar humerus (SCH) fractures is commonly used but inconsistently defined regarding type 1 and type 2 (posteriorly hinged) SCH fractures. This study examined the reliability of the anterior humeral line (AHL) index compared with the Gartland classification. Fifty consecutive SCH fractures on anteroposterior and lateral elbow radiographs in pediatric patients (age range, 18 months to 15 years) were classified by 11 observers (9 attendings and 2 residents) according to the Gartland classification (types 1, 2, and 3) and the AHL index (AHL0, AHL passes anterior to the capitellum; AHL1, anterior one-third capitellum; and AHL2, middle one-third capitellum), with recommendations for treatment (cast immobilization vs surgery)...

BACKGROUND: Proximal humerus fractures are the third most common in the human body but their management remains controversial. Open reduction and internal fixation with plates is one of the leading modes of operative treatment for these fractures. The development of technologies and techniques for these plates, during the recent decades, promise a bright future for their clinical use. A comprehensive review of in vitro biomechanical studies is needed for the comparison of plates' mechanical performance and the testing methodologies...

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...

OBJECTIVE: Proximal humerus fractures are highly traumatic and debilitating. Surgical fixation may be contraindicated in older clients, thus requiring a systematic rehabilitation protocol. These clients may suffer loss of independence and require long-term assistance if not treated properly. METHOD: In this case report, we describe the occupation-based conservative rehabilitation of a retired male client after a four-part proximal humerus fracture. Outcome measurements used were the QuickDASH, the Numeric Rating Scale for Pain, goniometric measurements, and manual muscle testing...

Treatment of unicameral bone cysts (UBC) in the humerus with drainage screws is scarcely reported in the literature. The aim of this retrospective study was to compare drainage screws and alternative treatment methods with respect to the number of required surgical procedures to achieve sufficient UBC healing, postoperative fractures/recurrences/complications, and radiological outcome. Medical archives of two tertiary orthopedic referral centers were screened for all patients who were treated surgically for humeral UBC in the period 1991-2015 with a histologically/cytologically confirmed diagnosis...

PURPOSE: There are two widely used distal humerus fracture (DHF) fixation methods with either orthogonal or parallel double-plate osteosynthesis. However, biomechanical studies have shown inconsistent results on which technique is more effective. We performed a meta-analysis to compare these two fixation methods for adult DHF fixation. METHODS: We searched the literature for entries discussing the biomechanical testing of orthogonal and parallel fixation techniques for DHFs...

Older men who participated in a sporting activity were less likely to sustain any fracture or major osteoporotic fracture over a 6-year follow-up period. PURPOSE: Regular weight-bearing physical activity can reduce fracture risk through an increase in bone strength, as well as reducing falls risk by improving muscle strength and balance. In this study, we aimed to determine whether a specific type of physical activity, sports participation, reduces fracture risk in older Australian men...
