Fizz-computed tomography as a novel modality of objective esophageal hiatal assessment.

Background: Traditional investigations of esophageal hiatal assessment for reflux disease and hiatal hernia (HH), such as endoscopy and barium swallow are subjective. High resolution manometry (HRM) limits hiatal hernia assessment to vertical length. We report a novel use of 3D volumetric Computed Tomography with effervescent oral contrast (Fizz-CT) as a means of preoperative HH diagnosis.

Outcome of uncemented trapeziometacarpal prosthesis for treatment of thumb carpometacarpal joint arthritis.

Background: Osteoarthritis of the trapeziometacarpal joint of thumb occurs frequently and can be very disabling. Numerous surgical techniques including trapeziectomy with or without tendon interposition arthrodesis and partial or total joint arthroplasty with cemented and noncemented prosthesis have been described for the treatment of trapeziometacarpal joint osteoarthritis. Initial problems of osteolysis and implant loosening have been substantially reduced with improvement in implant design.
