Knee kinematics and in situ forces resulting from anterior cruciate ligament reconstructions with 2 femoral tunnel positions were evaluated.A graft placed inside the anatomical footprint of will restore knee function better than a at position for best isometry.Controlled laboratory study.Ten cadaveric knees tested response to 134-N load combined 10-N.m valgus 5-N.m internal rotation load. A robotic universal force-moment sensor testing system was used apply loads, recorded. An active...

We studied seven patients who had isolated loss of the proximal attachment tendon long head biceps brachii, documented operatively or with magnetic resonance imaging, in order to identify and measure superior translation humeral on glenoid. Four true anteroposterior radiographs were made both shoulders, before after operation, 0, 45, 90, 120 degrees abduction scapular plane. managed arthroscopic acromioplasty an open tenodesis; one, tenodesis alone; debridement a ruptured stump; remaining...

Patellofemoral pain is associated with patellar malalignment and quadriceps weakness which are seen more commonly in women. The objective of the current study was to determine effects gender, vastus medialis strength, tibial rotation on patellofemoral joint biomechanics. Twelve fresh-frozen knees from cadavers were tested using a custom knee jig. Anatomic multiplane loading extensor mechanism used varying loads. contact area pressure measured sensitive film at flexion angles 0 degrees, 30 60...

The loads needed to elicit a positive pivot shift test in knee with an anterior cruciate ligament (ACL) rupture have not been quantified. coupled tibial translation (ATT), internal rotation (ITR), and the situ force ACL response valgus torque, inherent component of test, were measured 10 human cadaveric specimens. Using robotic/universal force-moment sensor testing system, torques ranging from 0.0 10.0 Nm applied nine increments on intact ACL-deficient flexion 0 degrees 90 degrees. At 15...

To evaluate the predictive accuracy of Palliative Prognostic (PaP) score in patients with advanced cancer under care an oncologist.The PaP was calculated 100 consecutive hospitalized a medical or radiation oncologist at university teaching hospital Australia. The attending predicted survival duration for purpose scoring. positive value evaluated. Survival analysis performed to compare three prognostic groups.Assessable data were available 98 patients. overall median 12 weeks (interquartile...

We evaluated the effect of simulated scapular protraction on anterior glenohumeral translation and in situ inferior ligament strain. Five fresh-frozen cadaveric joints were tested position apprehension while simulating using a custom testing device differential variable reluctance transducer. The results showed statistically significant decrease as scapula was increasingly rotated to simulate 20° protraction. With 15 N thorax-based, anteriorly directed load, mean 6.3 1.6 mm (mean SEM). 10°...

Advances in smartphone photography (both quality and image transmission) may improve access to care via direct parent-to-clinician telemedicine. However, the accuracy of diagnoses that are reliant on parent-provided photographs has not been formally compared with made person.To assess whether pediatric skin conditions taken by parents sufficient permit accurate diagnosis.A prospective study was conducted among 40 patient-parent dyads at a dermatology clinic Children's Hospital Philadelphia...

This is a retrospective study of 10 patients with combined cruciate ligament and posterolateral instability who underwent surgical reconstruction between 1991 1994. All knees had at least 20 degrees increased external rotation 30 knee flexion from 1+ to 3+ varus instability. Five posterior ruptures 2+ Lachman test result. (One both anterior injuries). In all cases the lateral collateral was reconstructed bone-patellar tendon-bone allograft secured interference screws. Fixation tunnels were...

We reviewed the hospital records of 371 children who were suspected having been physically abused. Our purpose was to determine specific features that might be used distinguish injuries resulting from abuse accidental injuries. Soft-tissue found in 341 (92 per cent) these children. Ecchymoses most common, accounting for 555 (62 892 soft-tissue injuries, and very few had a suspicious pattern. Only thirty-four (9 radiographically documented fracture, but radiography performed only thirty-seven...

The purpose of this study was to determine whether there are changes in anterior and posterior glenohumeral translation after arthroscopic, nonablative, thermal capsuloplasty with a laser. Two anteriorly two posteriorly directed loads were sequentially applied the humerus nine cadaveric joints, on glenoid measured. rigidly fixed, joint positioned simulating 90 degrees shoulder abduction external rotation. Using holmium:yttrium-aluminum-garnet laser, energy then capsuloligamentous structures...

Background Patients with glenohumeral instability have proprioceptive deficits that are suggested to contribute muscle activation alterations. Hypothesis Muscle alterations will be present in shoulders anterior instability. Study Design Posttest-only control group design. Methods Eleven patients diagnosed were matched 11 subjects. Each subject received an external humeral rotation apprehension perturbation while reflexive characteristics measured indwelling electromyography and surface...

Different operative techniques for transfer of the pectoralis major tendon have been proposed treatment irreparable ruptures subscapularis tendon. The objective this study was to compare effects two transferring (above or underneath conjoint tendon) on glenohumeral kinematics during active abduction in a biomechanical model subscapularis-deficient shoulder.Six shoulder specimens were tested with custom dynamic testing apparatus. After intact recorded, complete tear simulated surgically. A...
