A picture identification test for measuring speech discrimination ability in hearing-impaired children was developed two phases. In the first phase word stimuli were evaluated to determine whether they within recognition vocabulary of and pictorial representations words adequate. Before second phase, revised consist 25 plates with 6 pictures on each plate, only 4 plate used as stimuli. These lists given 61 separate occasions. The results indicate reliability coefficients excess 0.87 all four...

The task of selecting the electroacoustic characteristics hearing aids for young hearing-impaired children continues to challenge many clinical audiologists. rationale a theoretically based approach this problem is presented. Additionally, issues related choice an idealized speech spectrum theoretical selection model are considered in relation acoustic environment and auditory needs children. Finally, preliminary version computer assisted approach, which facilitates initial frequency/gain...

<b>Background</b> Scapholunate reconstruction poses a challenge to orthopedic surgeons. <b>Materials and Methods</b> Prospective cohort. <b>Description of Technique</b> Our technique for scapholunate (SL) involves ligament utilizing portion the flexor carpi radialis tendon rerouted via transosseous tunnels across scaphoid, lunate, triquetrum (scapholunotriquetral tenodesis). The graft is secured with interference screw fixation into triquetrum. philosophy this new reduce subluxation maintain...

There are concerns regarding glenoid erosion with metal shoulder hemiarthroplasty. PyroCarbon may offer an alternative because of favorable wear characteristics and preservation the glenoid. The purpose this study was to assess in vitro bone relative cobalt chromium alloy hemiarthroplasty a simulator.Wear prostheses articulating were characterized by means penetration rate, changes surface roughness, particle analysis.PyroCarbon produced significantly less damage damaged than prostheses....

Abstract Objective This study aimed to evaluate the appearance, timing, and pattern of enhancement on magnetic resonance imaging (MRI) associated with triangular fibrocartilage complex (TFCC) scapholunate interosseous ligament (SLIL) tears. Materials Methods A retrospective review patients TFCC SLIL tears identified MRI was conducted determine patterns timelines after a gadolinium injection. The appearances were compared postcontrast in group asymptomatic controls who presented non-traumatic...

<b>Background</b> Instability of the distal radioulnar joint (DRUJ) is a complication that can occur following radius fracture or malunion. We have observed residual radial translation radius, relative to shaft, may be causal factor DRUJ instability, even once traditional radiographic parameters (volar tilt, inclination, and ulnar variance) been restored. Residual fragment cause detensioning interosseous membrane (IOM) pronator quadratus with poor apposition between head sigmoid notch. This...

Abstract Background M agnetic resonance imaging ( MRI ) is being increasingly utilized to define pathology and guide treatment in patients presenting with wrist pain. The clinical relevance of identified or confirmed has not been established, the prevalence asymptomatic known. Methods Twenty volunteers no previous injury symptoms underwent bilateral studies this exploratory diagnostic study. scans were reported by an experienced musculoskeletal radiologist surgeon, a consensus reached on...

We evaluated four potential secondary magnetic resonance imaging signs to aid in clinical diagnosis of posterior tibial tendon (PTT) tears. Seventy-one ankles (25 PTT tears and 46 controls) were for the following signs: (1) sheath fluid, (2) a distal spur located just anterior PTT, (3) unroofing talus, (4) "bone bruise"--like medullary lesions. Two musculoskeletal radiologists rated their confidence using scale compared level agreement. The presence fluid had modest specificity fair moderate...

This paper reports the results of fixation intraarticular fractures distal radius using TriMed fragment-specific system by surgeons early in their experience with system. A consecutive series 22 AO types C2 and C3 21 patients were internally fixed Restoration articular congruity to less than 2 mm was possible 20 fractures. At a minimum 6 months follow-up, mean volar radial inclination 8 degrees 25 , respectively, no loss reduction. The had 50 flexion, 63 extension pronation-supination arc...

The surgical treatment of post-traumatic radioulnar synostosis is difficult. Recurrence after resection alone a concern with poor long-term maintenance forearm rotation. We report on the use pedicled adipofascial flaps to prevent recurrence and facilitate movement in six adult patients synostosis. Five involved proximal joint one distal joint. In four flap was based radial artery two posterior interosseous artery. Mean intraoperative supination 78° pronation 76°. follow up 32 months. At...
