The clinical outcome for patients with documented rerupture after open repair of one or more rotator cuff tendons is not well known. purpose this study was to evaluate the outcomes a consecutive series reruptures and provide information concerning advisability in situations which there may be high probability rerupture.During prospective follow-up repairs, we detected, magnetic resonance imaging, structural failure twenty patients, who had mean age fifty-nine years at time repair. All were...

Background: At a mean follow-up of 3.1 years, twenty-seven consecutive repairs massive rotator cuff tears yielded good and excellent clinical results despite retear rate 37%. Patients with had improvement over the preoperative state, but those structurally intact repair substantially better result. The purpose this study was to reassess same patients determine long-term functional structural results. Methods: interval 9.9 twenty-three returned for review were examined clinically,...

Isolated tears of the subscapularis occur less commonly than those involving superior and posterior components rotator cuff. The purpose present study was to evaluate structural integrity clinical outcomes after arthroscopic repair isolated tears.A prospective seventeen consecutive patients who were managed with an all-arthroscopic tendon performed. group included thirteen men four women had average age forty-seven years at time surgery. interval from onset symptoms surgery twenty-four...

A computer-assisted planning and visualization system (the Orthopaedic Surgery Planning System) was tested for pedicle screw insertion in vivo.To evaluate the system's applicability regular intraoperative use its accuracy placement vivo.Pedicle poses considerable anatomic biomechanical risks. The reported rates of misplacement with conventional techniques are unacceptably high. It previously has been shown vitro that computer assistance offers potential to decrease number screws perforating...

Background: The natural history of massive rotator cuff tears is not well known. purpose this study was to determine the clinical and structural mid-term outcomes in a series nonoperatively managed tears. Methods: Nineteen consecutive patients (twelve men seven women; average age, sixty-four years) with tear, documented by magnetic resonance imaging, were identified retrospectively. There six complete two tendons thirteen three tendons. All exclusively nonoperative means. Nonoperative...

In a previous study, twenty consecutive patients with rerupture of the rotator cuff, as documented magnetic resonance imaging, were found to have significantly less pain and better function strength, compared preoperative state, at 3.2 years postoperatively. It was purpose this study determine clinical structural outcomes these reruptures in same after longer period follow-up.At mean 7.6 postoperatively, reexamined clinically standard radiographs imaging use clinical, radiographic, criteria...

Background: The treatment of recurrent posterior instability the shoulder, especially when it is associated with voluntary subluxation, remains controversial, and operative correction generally not advised. Methods: results subluxation in a consecutive series twenty-six shoulders twenty-four patients were reviewed. Eighteen on dominant side. average age was years (range, fifteen to thirty-three years). All had involuntary as well instability, but none psychiatric disorder. Only five...

To prospectively evaluate the signal intensity (SI), course, and diameter of elbow nerves to identify anatomic variants that are potentially associated with nerve compression syndromes on magnetic resonance (MR) images asymptomatic elbows.This study was approved by institutional review board. Informed consent obtained from each volunteer. Sixty subjects elbows (age range, 22.4-51.7 years; median age, 32.8 years) underwent MR imaging. Increased SI compared surrounding muscles fluid-sensitive...

Chronic tears of the subscapularis tendon with or without associated supraspinatus and infraspinatus tendons may lead to pain dysfunction shoulder. If conservative treatment fails repair musculotendinous unit is impossible, transfer pectoralis major can be attempted substitute for lost function.Twenty-eight patients underwent a total thirty consecutive transfers at an average age fifty-three years. There were twelve isolated eighteen tear infraspinatus. All examined clinically standard...

We performed a biomechanical study on human cadaver spines to determine the effect of three different interbody cage designs, with and without posterior instrumentation, three-dimensional flexibility spine. Six lumbar functional spinal units for each type were subjected multidirectional testing in four configurations: intact, cages from approach, additional cross-bracing. The tests involved application flexion extension, bilateral axial rotation lateral bending pure moments. relative...

ObjectiveThe aim of this study was to compare the responsiveness various patient-reported outcome measures (PROMs) and clinician-reported outcomes following total knee arthroplasty (TKA) over a 2-year period.MethodsData were collected in prospective cohort primary TKA. Patients who had completed Forgotten Joint Score-12 (FJS-12), Western Ontario McMaster Universities (WOMAC) osteoarthritis (OA) index, EQ-5D, Knee Society Score range movement (ROM) assessment included. Five time points...

Our study aimed at developing clinical thresholds (cut-off scores) for the Western Ontario and McMaster Universities (WOMAC) osteoarthritis index, EQ-5D Knee Society Score discriminating between patients with without treatment success following total knee arthroplasty (TKA). We performed a retrospective analysis of 1055 2 months after TKA 765 1 year TKA. considered successful if patient reported high levels satisfaction pain relief, functional increase, willingness to undergo same procedure...

Background Beach volleyball is an Olympic overhead sport. It not well known which clinical and imaging findings are normal associated with symptoms. Hypothesis There typical in the hitting shoulders of fully competitive professional beach players, as compared their nonhitting shoulders. Study Design Cross-sectional study; Level evidence, 3. Methods During Volleyball Grand Slam Tournament Klagenfurt, Austria, 84 players (54 men, 30 women) underwent a questionnaire-based interview complete...

Osteoporosis may complicate surgical fixation and healing of proximal humerus fractures should be assessed preoperatively. Peripheral quantitative CT (pQCT) the Tingart measurement are helpful methods, but both have limitations in clinical use because limited availability or fracture lines crossing area interest (Tingart measurement). The aim our study was to introduce validate a simple cortical index assess quality bone using AP radiographs.We asked: (1) How do deltoid tuberosity correlate...

The natural history of small, symptomatic rotator cuff tears is currently unclear. purpose the present study was to assess clinical and structural outcomes for a consecutive series patients with symptomatic, isolated full-thickness supraspinatus who had been offered repair but declined operative treatment.In period, twenty-four that diagnosed by means magnetic resonance arthrography were elected nonoperative treatment. twenty men four women an average age fifty-two years at time diagnosis....
