Background: Spondylolysis defects detected by nuclear scintigraphy but not by plain radiographs represent early lesions. Functional outcome and eventual bony union of these defects are unknown. Hypothesis: Defects with greater degree of healing…
To investigate the source of bone brittleness in the disease osteogenesis imperfecta (OI), biomechanical properties have been measured in the femurs from a homozygous (oim/oim) mutant mouse model of OI, its heterozygous littermates, and wild-type…
Study Design. A descriptive study of the association between sacroiliac joint bridging ( SIB) and age, gender, laterality, and ethnic origin in a normal skeletal population. The effectiveness of radiographs in identifying SIB was also evaluated.…
Study Design. A descriptive study of the association between sacroiliac joint (extra-articular) bridging and other enthesopathies. Objectives. To examine the relationship between sacroiliac joint bridging with other entheseal reaction sites in the…
The purpose of this study is to critically investigate the anatomy of the deep posterior compartment of the leg, Specifically, the relationship of the deep posterior compartment to the superficial posterior compartment and their Insertion onto the…
Chronic obstructive pulmonary disease (COPD) was the third leading cause of mortality in the United States in 2009 and accounts for millions of dollars in health care expenses annually. It is characterized by slow declines in functional ability and…
Study Design. An aneurysmal bone cyst in the neural arch of the fourth cervical vertebra of a 10-year-old girl is reported, along with a brief review of the literature on the topic. Objective. To report the presentation and diagnosis of this disorder…
Intra-articular fractures of the tibial plafond are complex injuries which continue to challenge orthopaedic surgeons in achieving anatomic reduction, while allowing early weight bearing and return to activity. Although a wide range of treatment…
Ultrastructural studies of slipped capital femoral epiphysis (SCFE) growth plates have shown diminished cellularity and marked distortion of the architecture in the proliferative and hypertrophic zones. Chondrocyte degeneration and death were noted…
Numerous physiologic derangements can result when body-builders attempt to augment their muscle definition by using diuretics, potassium supplements, and dietary restrictions., A case report describes a 27-year-old male professional bodybuilder who…
Objectives: We evaluated the economic aspects of an orthopaedic trauma section at a regional Level 1, semi-academic community hospital. This study analyzes the economics of a dedicated hospital-based orthopaedic trauma program. Methods: Institutional…
Study Design. A description of a method for standardizing the nomenclature used in reporting the size and location of lesions in the lumbar or thoracic spine is presented. Objectives. To make the reporting of findings on computed tomography or…
Four groups were studied to determine the cooling effect at skin level of ice application over common ankle bandages and casts. The plaster cast, synthetic cast, and Ace(R) wrap dressing groups had 18 participants and the Robert-Jones dressing group…
Interbody cage devices, used to assist interbody fusion, are rapidly gaining popularity in the surgical management of chronic low back pain. This update provides a structural classification of commonly used devices and assesses them against a set of…
Study Design. A description of the technique for lumbar microdecompression and a prospective study of the outcomes. Objective. To describe and analyze a technique that affords an excellent decompression while minimizing damage to surrounding tissues.…
Objective: In the early 1970s, the Akron dome osteotomy was developed as a salvage surgical option to manage rigid cavus deformity of the foot. This study represents an updated review of surgical cases between 1972 and 2001 constituting 89 patients…
Purpose: Surgical correction of the hip and knee in patients with diastrophic dysplasia is extremely difficult secondary to the markedly distorted pathoanatomy of both the bone and soft tissues. The objective of this study is to provide a…
Background: Surgical correction of the foot and ankle in patients with diastrophic dysplasia is extremely difficult secondary to the markedly distorted pathoanatomy. Several authors have described superficially some of the clinical and radiographic…
Lateral column calcaneal lengthening as described by Mosca is a widely accepted technique for the correction of hindfoot valgus and pes planus. It is performed with both allogeneic and autogenous bone graft. The purpose of this study was to evaluate…
As a potential means of comparing hypothyroidism in humans, this work intended to establish a defined hypothyroid state in immature miniature swine and evaluate specific molecular, cellular, and extracellular responses of their growth plates. Two…
Vertically unstable sacral fractures often make it difficult to achieve rigid fixation and there is no consensus on the optimal fixation technique for these injuries. The purpose of this Study was to evaluate complication rate and short-term outcome…
