Direct and indirect costs associated with nonoperative treatment for shoulder instability: an observational study in 132 patients.

Background: Shoulder instability is associated with decreased functioning. The associated costs could be substantial and interesting to clinicians, researchers, and policy makers. This prospective observational study aims to (1) estimate productivity losses and healthcare expenses following the nonoperative treatment of shoulder instability and (2) identify patient characteristics that influence societal costs.

Quantitative 3-dimensional Computerized Tomography Modeling of Isolated Greater Tuberosity Fractures with and without Shoulder Dislocation.

Background: The aim of this study was to assess differences in fracture morphology and displacement between isolated greater tuberosity (GT) fractures (i.e. fractures of the greater tuberosity without other fractures of the proximal humerus) with and without shoulder dislocation utilizing quantitative 3-dimensional CT imaging.

Melone's Concept Revisited: 3D Quantification of Fragment Displacement.

We applied quantitative 3D computed tomography to 50 complete articular AO type C fractures of the distal radius and tested the null hypothesis that fracture fragments can be divided according to Melone's concept (radial styloid and volar and dorsal lunate facet fragments) and that each fragment has similar (1) displacement and (2) articular surface area. Thirty-eight fractures fit the Melone distribution of fragments. Radial styloid fragments were most displaced, and volar lunate fragments were least displaced.

Progression of Heterotopic Ossification around the Elbow after Trauma.

Background: This study addresses the null hypothesis that there is no expansion of heterotopic ossification (HO) in the elbow beyond what can be seen early on.

Methods: The area of HO was measured on lateral radiographs of 38 consecutive patients that had operative treatment of HO between 2000 and 2013. Measurements from radiographs obtained between 3 to 7 weeks were compared to measurements from radiographs made 3 months or more after injury.

Quantitative three-dimensional computed tomography analysis of glenoid fracture patterns according to the AO/OTA classification.

Hypothesis/background: This study measures the characteristics of glenoid fractures to determine if the AO Foundation and Orthopaedic Trauma Association (AO/OTA) classification captures the most common fracture patterns. The primary null hypothesis was that surface area and degree of fragmentation do not differ among the different fracture types. Secondarily, we tested if there was a relationship between high- vs.

What Is the Radiographic Prevalence of Incidental Kienböck Disease?

Background: Kienböck disease is characterized by osteonecrosis of the lunate. Not all patients with radiographic evidence of the disease experience symptoms bothersome enough to consult a doctor. Little research has been performed on the prevalence of Kienböck disease, and the prevalence in the asymptomatic population is unclear.

Quantitative 3-dimensional CT analyses of fractures of the middle phalanx base.

Background: Quantitative 3-dimensional computed tomography (3DCT) analyses can provide a more detailed understanding of fracture morphology. For fracture-dislocation of the proximal interphalangeal joint, the extent of fragmentation of the volar lip of the middle phalanx-a factor that might influence treatment-is not always apparent from radiographs. We hypothesized that there is no correlation between number of fracture fragments and the percentage of articular surface area involved in intra-articular fractures of the base of the middle phalanx using quantitative 3DCT analyses.

[Scapula alata following a gunshot injury].

Background: The clinical condition "winged scapula" (scapula alata) is frequently not recognized as such. The accompanying symptoms are often attributed to more frequently occurring shoulder disorders, which can lead to unnecessary surgical procedures.

Case Description: A 41-year-old man was shot during a robbery 3 years ago, resulting in a complete paraplegia from the fourth thoracic vertebra downwards.

Does verbal and nonverbal communication of pain correlate with disability?

Background: Illness (symptoms and disability) consistently correlates more with coping strategies and symptoms of depression than with pathophysiology or impairment.

Objective: This study tested the primary null hypothesis that there is no correlation between verbal and nonverbal communication of pain (pain behavior) and upper extremity-specific disability in patients with hand and upper extremity illness.

Methods: A total of 139 new and followed up adult patients completed the QuickDASH, an ordinal rating of pain, and 4 Patient-Reported Outcomes Measurement Information System (PROMIS) Computer Adaptive Testing instruments: (1) PROMIS pain behavior, (2) PROMIS pain interference (measuring the degree to which pain interferes with achieving ones physical goals), (3) PROMIS physical function, and (4) PROMIS depression.

A preliminary RCT of a mind body skills based intervention addressing mood and coping strategies in patients with acute orthopaedic trauma.

Objective: To test the acceptability and feasibility of a mind body skills-based intervention (RRCB) and estimate its preliminary effect in reducing disability and pain intensity as compared to standard care (SC) in patients with acute musculoskeletal trauma.

Design: Randomised controlled trial.

Setting: Level I trauma centre.

Estimation of base of middle phalanx size using anatomical landmarks.

Purpose: To determine whether there is a measurable and reproducible relationship between the articular surface size of the middle phalanx base and the size of the middle phalanx head and proximal phalanx length of the same finger.

Methods: Size of the articular surface of the middle phalanx base, size of the middle phalanx head, and proximal phalanx length were measured in 84 lateral radiographs by 3 observers.

Results: The ratio of articular surface size of the middle phalanx base to the proximal phalanx length of the same finger was 0.
