HYPOTHESIS This study examined national trends and projections of procedure volumes and prevalence rates for shoulder and elbow arthroplasty in the United States (U.S.). This study hypothesized that the growth in demand for upper extremity arthroplasty will be greater than the growth in demand for hip and knee arthroplasty and that demand for these(More)
We studied the morphology of the thoracic vertebrae in the spines of seventeen human cadavera in order to define parameters that could be used as guidelines for the placement of hooks and screws in the pedicles to obtain internal fixation. We also reviewed computerized tomographic scans of nineteen thoracic spines in living patients who had no evidence of(More)
BACKGROUND Elbow tenderness and pain with resisted wrist extension are common manifestations of lateral epicondylar tendinopathy, also known as tennis elbow. Previous studies have suggested platelet-rich plasma (PRP) to be a safe and effective therapy for tennis elbow. PURPOSE To evaluate the clinical value of tendon needling with PRP in patients with(More)
Rupture of the distal biceps tendon occurs most commonly in the dominant extremity of men between 40 and 60 years of age when an unexpected extension force is applied to the flexed arm. Although previously thought to be an uncommon injury, distal biceps tendon ruptures are being reported with increasing frequency. The rupture typically occurs at the tendon(More)
Nineteen consecutive patients treated surgically for meso-os acromiale and subacromial pathology were reviewed retrospectively, with a mean length of follow-up of 40 months (range, 24-94 months). Of the patients, 11 (58%) were treated with acromioplasty in the presence of a stable os acromiale; 8 patients (42%) underwent open reduction-internal fixation for(More)
Closed reduction and percutaneous fixation is a viable treatment option for displaced two-part, three-part, and valgus-impacted four-part proximal humerus fractures. Despite biomechanical studies demonstrating inferior stability compared with plate and intramedullary nail constructs, percutaneous fixation offers a minimally invasive approach with potential(More)
Osteochondral lesions of the glenohumeral joint in early stages and in younger patients are an important problem and present a challenge during clinical decision making. Although prosthetic arthroplasty remains the gold standard for treatment in later stages of the disease, alternatives are desirable in the early stages and in young patients. The purposes(More)
UNLABELLED In the hands of an experienced arthroscopist, arthroscopic decompression of a spinoglenoid notch cyst can lead to resolution of a patient's symptoms and complete functional recovery. In our study, we hypothesized that patients with a spinoglenoid notch cyst who were treated arthroscopically would have return to near normal function of their(More)
We retrospectively reviewed 32 patients who underwent glenoid revision surgery after total shoulder arthroplasty to compare the results of revision total shoulder arthroplasty with those of revision hemiarthroplasty and to identify factors associated with poor results after revision shoulder arthroplasty for glenoid component loosening. Results were(More)
Ganglion cysts causing suprascapular nerve compression are an uncommon cause of suprascapular nerve compression. The advent of magnetic resonance imaging (MRI) and its application in patients with shoulder pain has improved the ability to diagnose cystic lesions causing extrinsic compression of the suprascapular nerve. Traditionally, treatment of(More)
