Active clinical trials for "Necrosis"

Today there are various surgical techniques for inguinal hernia. In this study, investigators want to compare the ''PIRS'' operating technique laparoscopy and modified "Marcy" operating technique with open inguinal access. Investigators would compare both groups to find out witch one does the lesser inflammatory stress response on the organism.

The objective of this study is to evaluate clinical performance for the commercially available NexGen TM Monoblock Tibia and NexGen TM Modular Tibia used in primary cementless tibia total knee arthroplasty.

Comparing the postoperative pain resulting after mechanical instrumentation using Reciproc reciprocating files versus that resulting after using ProTaper Next rotary files in asymptomatic necrotic molars.

A clinical trial of total Hip system used in Primary Total Hip Arthroplasty in China.

This multi-center exploratory clinical trial is a randomized trial designed to test whether a regenerative endodontic procedure using tissue engineering principles (REGENDO), or a revascularization (REVASC) endodontic procedure, in comparison to standard apexification treatment using a mineral trioxide aggregate barrier (apexification; APEX), produces a significantly better composite clinical outcome for the treatment of immature permanent teeth with pulpal necrosis.

The proposed study is a double-blinded randomized controlled trial comparing patient specific instruments with solely standardized instruments and pre-operative planning used for the placement of the acetabular cup prosthesis used in total hip arthroplasty. The investigators will enroll 36 patients who have consented to total hip arthroplasty for treatment of hip pathology. This treatment is a standard of care. Patients will receive standard of care pre- and post-operative care and placement of standard of care implants all of which are commercially available and FDA approved for general use for the clinical indications used in these patients. All patients will receive a pre-operative CT scan for surgical planning and comparison with post-operative CT scan. The difference in intervention between the groups will be the creation and use of patient specific instruments from the pre-operative planning session. These instruments will be used for placement of an indexing peripheral guide wire to direct acetabular preparation and placement of the shell assisting standard surgical instruments. Print-offs from the pre-operative plan will also be used in the treatment group. The post-operative scan will be performed within two weeks of the surgery for both the treatment and control groups. The investigators will analyze the difference in acetabular shell placement (acetabular version and abduction angle) from the pre-operatively planned CT scan. These differences will be compared between the control and experimental groups.

The purpose of this study is to evaluate the clinical performance of the rotating platform and fixed bearing implants in patients undergoing primary total knee replacement. Outcome scoring and radiographic assessment will be the methods used to evaluate performance.

Recruited patients with immature permanent maxillary anterior teeth with non-vital pulp, and periapical radiolucency, age ranging from 8 to16 years old were randomly allocated into three groups (n=13): Group I, disinfected using the triple antibiotic paste, Group II, disinfection was done using diode laser, and Group III, were disinfected using the triple antibiotic paste, diode laser was used for biostimulation. All groups were evaluated for the increase in root length and thickness and decrease in apical diameter at baseline, 3, 6, 9, and 12 months after treatment

This study was conducted to evaluate Calcium Hydroxide mixed with Gingerols versus Metapex in treatment of primary teeth with infected necrotic pulp

In the past years several shoulder reconstruction systems with different types of prostheses and fixation methods have been developed to improve shoulder arthroplasty, trying to cover a wide range of pathologies and revision situations. The aim of the present study is to report radiological and clinical outcome with a stemless shoulder implant with hollow screw fixation.
