No clinical and functional benefit after medial congruent compared to ultra congruent total knee arthroplasty at 1 year: A prospective randomized controlled study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Various conforming bearing designs are used during total knee arthroplasty (TKA), yet their impact on clinical outcomes remains uncertain. In recent years, the use of medial congruent (MC) and ultra congruent (UC) onlays has gained popularity.

Design of a hip screw for injection of bone cement

, 2006
Fracture to the neck of femur is frequently stabilised with a hip screw system, however the host bone is often weak or osteoporotic. This causes premature failure of the system, commonly by cut-out of the lag screw through the head of the femur.

Hearing Preservation Rates After Cochlear Implantation Using Soft Surgery Techniques

The Laryngoscope, EarlyView.
ABSTRACT Objectives To determine if hearing preservation rates after cochlear implantation varied over time with soft surgery techniques. Methods The hearing preservation rate over time in adult cochlear implant patients over 10 years was analyzed. The association between hearing preservation rate and sex, age, perioperative steroid dose, and type of ...

Monitoring of historical structural materials with computed tomography

Structural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.

Reconstruction of Post-Traumatic Frontal-Bone Depression Using Hydroxyapatite Cement

, 2009
The safety and efficacy of hydroxyapatite cement (Bone Source, Howmedica, Leibinger, Inc. Dallas, TX) use for the augmentation of post-traumatic frontal-bone depression was evaluated in a study of 20 consecutive oriental patients between June 1998 and ...

Split‐disk testing of precast ultra‐high performance fiber‐reinforced concrete tubes

Structural Concrete, EarlyView.
Abstract Ultra‐high performance fiber‐reinforced concrete (UHPFRC) has great potential for structural applications involving precast cylindrical shapes, including pipes, silos and stay‐in‐place forms for concrete columns. This study examines the performance of UHPFRC rings under internal pressure simulated using the split‐disk loading method, along ...
