Knowledge of the plantar foot shape alteration under weight bearing can offer implications for the design and construction of a comfortable and functional foot support. The purpose of this study was to quantify the change in three-dimensional foot shape under different weight-bearing conditions. The plantar foot shapes of 16 normal feet were collected by an impression casting method under three...

PURPOSE Correlations between maximum flexion and functional outcomes in total knee arthroplasty (TKA) patients are reportedly weak. We investigated whether there are differences between passive maximum flexion in nonweight bearing and other types of maximum flexion and whether the type of maximum flexion correlates with functional outcomes. MATERIALS AND METHODS A total of 210 patients (359 k...

The effect of weight-bearing on the height of the patellar using four radiological indices was studied in 25 healthy men using lateral radiographs of the knee in 30 degrees of flexion non-weight-bearing and weight-bearing. The position of the patella was quantified using the Insall-Salvati, the modified Insall-Salvati, the Blackburne-Peel and the Caton indices. The contraction of the quadriceps...

OBJECTIVE To monitor the concentration of markers of cartilage and synovium metabolism in the knee (stifle) joint synovial fluid of young beagles subjected to immobilisation and subsequent remobilisation. METHODS The right hind limb of 17 dogs was immobilised in flexion for 11 weeks. Simultaneously, the contralateral left knee was exposed to increased weight bearing. The remobilisation period...

Introduction: Transcuneiform fracture patterns without dislocations are uncommon. In a review of the literature, numerous case reports describe cuneiform fracture-dislocations involving either the transmetatarsal or midtarsal joint complexes due to direct trauma; however, an isolated transcuneiform fracture pattern without dislocation has not been reported. Methods: We present a rare injury of ...

The acute rupture of the Achilles tendon is a protracted injury. Surgery is only the beginning of a long rehabilitation period. Therefore, the rehabilitation protocol is an integral aspect to restore the pre-injury activity level. Despite several trials available comparing different treatment regimes, there is still no consensus regarding the optimal protocol. Consequently, the aim of our study...

Background: Creating a socket with proper fit is an important factor to ensure the comfort and control of prosthetic devices. Several techniques are commonly used to cast transtibial stumps but their effect on stump shape deformation is not well understood. This study compares the dimensions, circumferences and volumes of the positive casts and also the socket comfort between two casting method...

As composites are being used as primary load bearing members, the increased understanding of damage tolerance of the material is becoming important. When load is applied to a structure containing a crack or damage, a small area ahead of the crack undergoes very high stress. These stresses cause further damage in this small zone. Initially this damage is at the microlevel: in isotropic materials...

CONTEXT In clinical practice, the range of motion (ROM) of the non involved side often serves as the reference for comparison with the injured side. Previous investigations of non-weight-bearing (NWB) ankle dorsiflexion (DF) ROM measurements have indicated bilateral symmetry for the most part. Less is known about ankle DF measured under weight-bearing (WB) conditions. Because WB and NWB ankle D...

Structural glass combined with a timber frame is a composite system that has a predisposition for good behavior during an earthquake, it is energy-efficient and cost-effective, aesthetically acceptable and has a good load-bearing characteristics. In recent years, several research projects of composite systems timber structural glass are in progress and according to the present results basic gui...
