Targeted four-dimensional computerized tomography scans for elbow disorders: a literature review and refinement of existing technique with two exemplar cases.

Background: Four-dimensional computerized tomographies (4D-CTs) or motion CTs in elbow disorders have several potential advantages over conventional static imaging such as a reduction of misdiagnoses, a more targeted surgical approach, better patient understanding of their condition and potentially faster operative times. However, the radiation dose is higher than conventional static CT scans so this should be used judiciously. Our study reviews the current literature for 4D-CTs in dynamic elbow disorders and provides a technical note describing radiation-reduced targeted elbow 4D-CTs (te4D-CT) with two exemplar cases alongside our recommendations for when te4D-CTs are indicated.

Four-dimensional computed tomography scan for dynamic elbow disorders: recommendations for clinical utility.

Background: Four-dimensional computed tomography (4D CT) is rapidly emerging as a diagnostic tool for the investigation of dynamic upper limb disorders. Dynamic elbow pathologies are challenging to diagnose, and at present, limitations exist in current imaging modalities.

Objective: We aimed to assess the clinical utility of 4D CT in detecting potential dynamic elbow disorders.

Unexplained Pain Post Total Knee Arthroplasty With an Oxford Knee Score ≥20 at 6 Months Predicts Good 2-Year Outcome.

Background: Total knee arthroplasty (TKA) is an effective procedure for end-stage osteoarthritis of the knee. Some patients experience persistent unexplained pain post-TKA despite normal investigations. The purpose of this study is to identify which of these patients are likely to improve without any surgical intervention.

Treatment of infected nonunion total knee arthroplasty periprosthetic fracture using a stemmed articulating spacer.

Background: We present a case of multifocal infection involving the left total hip replacement and the right total knee replacement of a patient, further complicated by an infected non-union of a periprosthetic fracture of the right knee. This required the unique simultaneous management of both infection eradication and fracture stabilization in the knee.

Methods: Both sites were treated with a two-stages procedure, including the novel use of a stemmed articulating spacer for the right knee.

Evaluation of medial-lateral stability and functional outcome following total knee arthroplasty: results of a single hospital joint registry.

A precept of a successful total knee arthroplasty (TKA) would be a well balanced, stable knee. We analyzed the effects of medial-lateral (ML) stability on functional outcome at 2years post-operatively. Prospectively collected Joint Registry data of all unilateral primary TKAs between 2004 and March 2008 were used.

An atypical presentation of acute pancreatitis after simultaneous bilateral total knee replacement: A case report.

Acute pancreatitis is a known post-operative complication, commonly after abdominal surgery rather than total knee arthroplasty. When complications occur, post total knee arthroplasty, they tend to be cardiovascular and neurological events, rarely involving the gastrointestinal system. Therefore, when gastrointestinal complications occur, especially if they present with atypical symptoms, this tends to result in a delay in diagnosis.
