Rationale: Damage control is a staged surgical approach to manage polytraumatized patients. The damage control approach comprises three steps. First, bleeding is controlled and fractures are stabilized temporarily; second, vital parameters are stabilized and the child is rewarmed in the intensive care unit; and third, the child is reoperated for definitive repair of injuries.

Background: Displaced lateral humeral condyle fractures in children are usually treated with open reduction and internal fixation. When treated operatively with Kirschner wires, the bent cut near side wire ends are either buried in the subcutaneous tissue or are left exposed. It is believed that burying the wires allows them to remain in longer and hence facilitate better union. Read More

Case: A 30-year-old man was found to have a posteriorly displaced osteochondral shear fracture of his left humeral head, likely from dislocation and relocation. The fragment was fixed in its native position using headless screws, and the patient regained full strength and range of motion within 9 months.

Conclusions: Osteochondral shear fractures of the humeral head appear to shear off the anteromedial articular joint surface after dislocation and relocation. Read More

Background: Medical image processing has facilitated simulation of 3-dimensional (3-D) corrective osteotomy, and 3-D rapid prototyping technology has further enabled the manufacturing of patient-matched surgical guides and implants (patient-matched instruments, or PMIs). However, 3-D corrective osteotomy using these technologies has not been the standard procedure. We aimed to prospectively verify the efficacy and safety of PMIs in corrective osteotomy for deformities of the upper extremity. Read More

Introduction: The Center for Medicare Services currently bundles all shoulder arthroplasties, total shoulder arthroplasty and reverse total shoulder arthroplasty, into one Diagnosis-Related Group on which bundled reimbursements are then further characterized. An arthroplasty performed for traumatic indications, such as fractures, may have a different postoperative course of care compared with the one being done for degenerative arthritis/osteoarthritis (OA), despite having the same Current Procedural Terminology (CPT) and Diagnosis-related Group code.

Methods: The 2012 to 2016 American College of Surgeons-National Surgical Quality Improvement Program databases were queried using CPT-23472 to retrieve records of patients undergoing total shoulder arthroplasty/reverse total shoulder arthroplasty for degenerative arthritis/OA or proximal humerus fracture.

Background: Osteoporosis constitutes a major public health problem, through its association with age-related fractures, particularly of the hip, vertebrae, distal forearm, and humerus. Over recent decades, it has evolved from being viewed as an inevitable consequence of ageing, to being recognised as a serious and eminently treatable disease.

Materials And Methods: In this article, we review the literature pertaining to the epidemiology of osteoporosis, associated health burden, approaches to risk assessment and treatment. Read More

Clinical management of a septic non-union of the distal humerus is challenging and is complicated by the diversity of potential treatments which are variably successful. We report a novel and very successful treatment of a 58-year-old man presenting an infected non-union of the right distal humerus, secondary to a closed fracture initially treated with two anatomic plates. After hardware removal, a two-stage reconstruction was performed. Read More

Background: Olecranon osteotomy is a commonly used method for obtaining adequate exposure of the articular surface in complex distal humeral fractures. We describe a new technique whereby a precontoured olecranon plate is first fixed to the olecranon, and a Gigli saw is used to perform the osteotomy while the plate is in place.

Methods: By use of a standard posterior approach, a precontoured olecranon plate is applied to the olecranon and affixed with screws both proximally and distally to the planned osteotomy site. Read More

Long bone fractures in racehorses may present as stress fractures which have a good prognosis, or complete fractures, which often result in a fatal outcome. In order to identify differences in modifiable management practices that may contribute to these outcomes, racing histories of horses with humeral or tibial fractures and of matched controls were examined. A retrospective case-control study of Australian Thoroughbred racehorses diagnosed with a fracture of the humerus or tibia by scintigraphy or at post-mortem between 2002 and 2016 was undertaken.

External fixation is currently used as the definitive mode of fracture stabilisation in the management of ˜50% of long-bone non-unions. Distinction between non-union and delayed union is a diagnostic dilemma especially in fractures healing by primary bone repair. This distinction is important, as non-unions are not necessarily part of the same spectrum as delayed unions. Read More

Introduction: Management of minimally displaced lateral humeral condyle fractures in pediatric patients is controversial. This is primarily because with current imaging modalities it is difficult to accurately and conveniently determine the stability of the fractures by detecting the integrity of the cartilage hinge. Nevertheless, transverse ultrasonography has not been intensively reported in previous studies. Read More

Although radiologists are likely familiar with basic fracture patterns around the shoulder, certain fracture types in this area have particularly relevant and controversial clinical management issues. These include proximal humeral fractures, in which conservative management is favored but some patients receive surgical treatment; glenoid fractures and Hill-Sachs lesions, in which surgery may be performed depending on the amount of bone loss; and distal clavicular fractures, in which certain displaced fractures have high rates of nonunion, but there is no clearly favored surgical technique. Knowledge of the different clinical issues and surgical options can aid the radiologist in identifying key imaging findings and creating a useful report. Read More

During mammalian pregnancy and lactation, the maternal demand for calcium is increased to satisfy fetus and newborn skeletal growth. In addition to the dietary intake, females use the calcium contained in their bones to supply this increased demand, leading to a decrease in maternal bone mineral content. In reproductive insectivorous female bats, bone loss has been described as a physiological cost of reproduction, due to the reported increased risk of bone fracture. Read More
