Two studies were conducted to assess whether distraction has drivelike effects on task performance. In both, the effects of distraction over all trials interacted significantly with the nature of the task; jlistraction tended to facilitate the performances of simple tasks and signirkantiy~impaired performance on complex tasks. Moreover, analyses focusing upon drive carryover effects generally r...

We present the outcome of the treatment of chronic post-traumatic contractures of the proximal interphalangeal joint by gradual distraction correction using an external fixator. A total of 30 consecutive patients with a mean age of 34 years (17 to 54) had distraction for a mean of 16 days (10 to 22). The fixator was removed after a mean of 29 days (16 to 40). Assessment at a mean of 34 months (...

INTRODUCTION Temporo-mandibular joint ankylosis is a common cause of acquired deformity in children. PURPOSE Surgical correction of the ankylosis only leaves the patient with an uncorrected mandibular deformity. This study was to evaluate the use of distraction osteogenesis for simultaneous correction of the mandibular deformity. MATERIAL This study was done on six children with temporo-man...

[Purpose] The purpose of this study was to examine the effects of manual therapy using joint mobilization and flexion-distraction techniques on chronic low back pain and disc heights. [Subjects] This study was conducted with 31 chronic low back pain patients who were divided into a manual therapy group (MTG; n=16) and a spinal decompression therapy group (SDTG; n=15). [Methods] The MTG was trea...

BACKGROUND Ankle joint distraction (AJD) avoids the potential complications associated with ankle fusion or total ankle replacement (TAR) in patients with advanced ankle osteoarthritis (OA). AJD could a tenable option to ankle fusion or TAR. METHODS A review has been performed on the role of AJD in advanced OA of the ankle. The exploration machine was MedLine. The keywords utilized were: join...

We investigated effectiveness and potential use of early diagnosis of hip joint dysplasia in German Shepherd dogs by X-ray examination comparing the conventional extension position I with compression-distraction method. In addition to that we also used Ortolani palpation technique and X-ray examination of the hip joint in order to obtain view of its dorsal acetabular rim (DAR) and dorsal acetab...

Purpose. Rotating hinge knee prostheses should provide a stable situation following reconstruction. We performed a biomechanical analysis to establish the association between design of the central rotational stem (peg) and implant's stability, in a theoretical setting. Methods. Six different rotating hinge designs were tested, and three observers performed two different measurements with a cust...

Introduction: Anterior cervical discectomy and fusion (ACDF) has been considered as the gold standard surgical treatment for degenerative pathologies. Some surgeons tend to use larger-sized interbody cages during ACDF restore index intervertebral disc height, hence, this study evaluated effect of on spine with under both static cyclic loading. Method: Twenty pre-operative personalized poro-hype...
