Predictive Factors of Neurovascular and Tendon Injuries Following Dog Bites to the Upper Extremity.
Background: Dog bite injuries to the upper extremity can result in traumatic neurovascular and musculotendinous damage. Currently, there are no clear guidelines dictating which patients may benefit from early operative exploration. The purpose of this study was to identify clinical variables that were predictive of abnormal intraoperative findings in patients who sustained an upper extremity dog bite injury. ⋯ One hundred percent of patients with an abnormal vascular physical exam had intraoperative arterial injury. Conclusions: To date, there are no clear guidelines on what clinical criteria indicate the need for operative exploration and possible repair of neurovascular structures in upper extremity dog bite injuries. In our study, nerve, tendon, and vascular abnormalities noted on physical exam were strongly predictive of discovering neurovascular and musculotendinous damage during surgical exploration.

Evaluation of Physical Examination Tests for Thumb Basal Joint Osteoarthritis.
We compare the ability of 3 diagnostic tests to reproduce the pain of basilar joint arthritis (BJA): the grind test, the lever test (grasping the first metacarpal just distal to the basal joint and shucking back and forth in radial and ulnar directions), and the metacarpophalangeal extension test. ⋯ The lever test was the diagnostic test that best reproduced the pain caused by thumb basal joint osteoarthritis. We recommend using the lever physical examination test when evaluating the patient with suspected basal joint osteoarthritis. The often-quoted grind test is of limited diagnostic value.

Assessment of Intra-articular Screw Penetration During Radial Head and Olecranon Locking Plate Fixation: A Cadaveric Study.
The purpose of this study is to evaluate the role of radiographic and clinical exams in predicting screw penetration into the proximal radioulnar joint and ulnohumeral joint during open reduction and internal fixation of the radial head and proximal ulna. ⋯ The study evaluates sensitivity and specificity of clinical and radiographic means when assessing for articular penetration of screws during olecranon and radial head locking plate fixation. Certain screw locations are more difficult to evaluate than others and may go undetected by standard means of assessment used in a surgical setting.

The use of a single volar locking plate for AO C3-type distal radius fractures.
A single volar locking plate (VLP) is now frequently used for open reduction and internal fixation (ORIF) of many types of distal radius fractures. Comminuted intra-articular distal radius fractures (AO C3-type) are typically the most challenging to surgically treat. No studies directly address the adequacy of a VLP alone for maintaining reduction of AO C-type fractures. We hypothesized that a single VLP provides an effective method for maintaining reduction for these fractures. ⋯ Level IV.

The role of fracture reduction and plate position in the aetiology of flexor pollicis longus tendon rupture after volar plate fixation of distal radius fractures.
Flexor pollicis longus (FPL) rupture has been described as complication following volar plating for distal radius fractures. It has been hypothesised that this is due to plate prominence. The aim of the study was to investigate the relationship between sub-optimal plate position and fracture reduction on plate prominence. ⋯ The results show a statistically and clinically significant effect of both plate position and fracture reduction on plate prominence and support the theory that both contribute to the aetiology of post-operative FPL rupture.
