Internal joint stabilizer for varus posteromedial rotatory instability of the elbow.

Background: Management of varus posteromedial rotatory instability (VPMRI) of the elbow presents a challenging problem, sometimes requiring supplemental external fixation or ulnohumeral cross-pinning. A relatively new treatment adjunct for posterolateral rotatory instability of the elbow has become available with the development of the internal joint stabilizer (IJS) implant. However, this has not been studied for VPMRI because the implant is thought to be ineffective at treating this instability when placed in the usual manner on the lateral side of the elbow.

Interposition Arthroplasty of the Elbow Utilizing a Lateral Epicondyle Osteotomy.

Management of severe elbow arthritis in young or active patients presents a challenging problem. Interposition arthroplasty is a useful salvage procedure for these patients but has a significant failure rate associated with postoperative instability. Previous studies have sought to preserve the integrity of the medial elbow ligament complex to decrease postoperative instability and the need for external fixation.

Distal Biceps Brachii Tendon Transfer for Re-establishing Extrinsic Finger Function: Feasibility Study in Cadavers.

Purpose: To determine the anatomic feasibility of transferring the biceps brachii tendon into either the extensor digitorum communis (EDC) or flexor digitorum profundus (FDP), determine the excursion imparted to EDC and FDP tendons after transfer, and compare the work capacity of the cadaver biceps to previously published data on the biceps as well as the recipient muscles by calculating the physiologic cross-sectional area (PCSA).

Methods: Four fresh-frozen cadaver shoulder-elbow-wrist specimens were used to measure tendon excursion that can be obtained with transfer of the distal biceps tendon into either the EDC or FDP. Two cadavers had distal biceps-to-EDC transfer performed, and the other 2 had distal biceps-to-FDP performed.

The role of exercise in heart failure: a systematic review.

The objective of this study was to examine the long-term effects of exercise on physiological function, functional capacity, and quality of life (QOL) and health status in patients with heart failure. PubMed and CENTRAL were searched (March 2001 to March 2011) for randomized controlled trials for the keyword "exercise heart failure." Data were abstracted by a single author (B.
