sternal non-union is a severe complication of sternotomy closure following open heart surgeries. healing problems typically occur in 0.3% to 5% of patients. technetium-99m methylene diphosphonate (99mtc-mdp) bone scintigraphy has been used to assess bone nonunion to predict the healing response for proper management. in this report, we present the case of a marked sternal nonunion following...
Scaphoid nonunion is a common but difficult problem for hand surgeons. The diagnosis of scaphoid nonunion is often delayed, and therefore, treatment must be tailored to the type of fracture, the duration of nonunion, and the presence or absence of resulting arthritis. This article reviews the diagnosis and work-up of scaphoid nonunion, classification schemes for scaphoid nonunion, and various t...
BACKGROUND Nonunion risk factor identification and modification are subjective. We describe and validate a predictive nonunion risk factor model to identify foot and ankle operative patients at risk for nonunion. MATERIALS AND METHODS One hundred international experts in foot and ankle surgery were surveyed. Nineteen nonunion risk factors were stratified into 3 categories: more significant th...
BACKGROUND Tibia shaft fractures (TSF) are common for men and women and cause substantial morbidity, healthcare use, and costs. The impact of nonunions on healthcare use and costs is poorly described. Our goal was to investigate patient characteristics and healthcare use and costs associated with TSF in patients with and without nonunion. METHODS We retrospectively analyzed medical claims in ...
Our aim was to develop a clinically relevant model of atrophic nonunion in the rat to test the hypothesis that the vessel density of atrophic nonunion reaches that of normal healing bone, but at a later time-point. Atrophic nonunion is usually attributed to impaired blood supply and is poorly understood. We determined the number of blood vessels at the site of an osteotomy using immunolocalisat...
PURPOSE Bupivacaine is commonly used for the treatment of back pain and the diagnosis of its origin. Nonunion is sometimes observed after spinal fusion surgery; however, whether the nonunion causes pain is controversial. In the current study, we aimed to detect painful nonunion by injecting bupivacaine into the disc space of patients with nonunion after anterior lumbar interbody fusion (ALIF) s...
OBJECTIVES A successful outcome following treatment of nonunion requires the correct identification of all of the underlying cause(s) and addressing them appropriately. The aim of this study was to assess the distribution and frequency of causative factors in a consecutive cohort of nonunion patients in order to optimise the management strategy for individual patients presenting with nonunion. ...
BACKGROUND Identification of patients at higher risk of nonunion after diaphyseal clavicular fractures is desirable to improve patient counseling and enable targeted surgical treatment. METHODS Seventy-nine percent (941 of 1196) of diaphyseal clavicular fractures were followed to union or nonunion. Demographic, injury, and radiographic characteristics associated with nonunion were determined ...
Nonunion is common complication of fracture management. Various factors are involved in its occurring. Metabolic and endocrine factors are often overlooked. So that aim of study was to evaluate the level of vitamin D and PTH in patients with unexplained nonunion and fractures due to low energy trauma. In the case control study, 30 patients with tibial nonunion compared with 32 patients with nor...
Nonunion following diaphyseal forearm fracture is an uncommon complication in children. Compression plate fixation with bone grafting has been the standard method to treat this complication. We report a case of hypertrophic nonunion of the ulna in a child who was treated surgically using an elastic stable intramedullary nail (ESIN) without bone grafting. The nonunion healed 4 months after surgery.
