Smartphone applications for the evaluation of pathologic shoulder range of motion and shoulder scores-a comparative study.

Hypothesis And Background: Accurate measurement of range of motion (ROM) is important in evaluating a pathologic shoulder and calculating shoulder scores. The aim of this study was to establish the reliability and validity of different smartphone applications (apps) in assessing pathologic shoulder ROM and to determine whether differences in recorded ROM measurements affect calculated shoulder scores. The authors hypothesized that there is no difference between shoulder ROM assessment methods and calculated shoulder scores.

Hip Disability and Osteoarthritis Outcome Score and Western Ontario and McMaster Universities Osteoarthritis Index Values in Asymptomatic and Arthritic Cohorts.

The primary aim of this study was to determine whether an electronic, multicenter data collection system could be used to establish normal population reference values for the Hip Disability and Osteoarthritis Outcome Score (HOOS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The secondary aim was to investigate differences in asymptomatic HOOS and WOMAC values reported in 2 geographically distinct English-speaking countries and compare these with a symptomatic arthritic patient cohort. A total of 552 participants were recruited.

Asymptomatic reference values for the Disability of Arm, Shoulder and Hand and Patient-Rated Wrist/Hand Evaluation - electronic data collection and its clinical implications.

The purpose of this study was to establish normal asymptomatic population values for the Disability of Arm, Shoulder and Hand and Patient-Rated Wrist/Hand Evaluation in healthy, asymptomatic individuals of different age, gender, ethnicity, handedness and nationality, using electronic data collection. Two-hundred and ninety-two Australian and 293 Canadian citizens with no active wrist pain, injury or pathology in their dominant hand, were evaluated. Participants completed an electronically administered questionnaire and were assessed clinically.

Asymptomatic population reference values for three knee patient-reported outcomes measures: evaluation of an electronic data collection system and implications for future international, multi-centre cohort studies.

Objectives: The aim was to assess whether the Knee Society Score, Oxford Knee Score (OKS) and Knee Injury and Osteoarthritis Outcome Score (KOOS) were comparable in asymptomatic, healthy, individuals of different age, gender and ethnicity, across two remote continents. The purpose of this study was to establish normal population values for these scores using an electronic data collection system.

Hypothesis: There is no difference in clinical knee scores in an asymptomatic population when comparing age, gender and ethnicity, across two remote continents.

An international, multicenter cohort study comparing 6 shoulder clinical scores in an asymptomatic population.

Hypothesis: The study purpose was to assess 6 shoulder patient-reported outcome measure (PROM) values in asymptomatic, healthy, pathology-free individuals. We hypothesized that there would be no difference in PROM values in pathology-free individuals when considering sex, age, ethnicity, and geographical location.

Methods: Electronic questionnaires were completed by 635 individuals (323 Australians and 312 Canadians) without dominant shoulder pathology for the American Shoulder and Elbow Surgeons (ASES) shoulder score; Constant-Murley Shoulder Score (CSS); Oxford Shoulder Score (OSS); University of California, Los Angeles (UCLA) shoulder score; Shoulder Pain and Disability Index (SPADI); and Stanmore Percentage of Normal Shoulder Assessment (SPONSA).

Normal population reference values for the Oxford and Harris Hip Scores - electronic data collection and its implications for clinical practice.

Background: The aim of this study was to assess whether the Harris Hip Score (HHS) and the Oxford Hip Score (OHS) were comparable in normal, healthy, pathology-free individuals of different age, gender, ethnicity, handedness and nationality. The purpose of this study was to establish normal population values for the HHS and OHS using an electronic data collection system.

Methods: 317 Australian and 310 Canadian citizens with no active hip pain, injury or pathology in the ipsilateral hip corresponding to their dominant arm, were evaluated.

A Pronator Teres-sparing Volar Approach for Osteosynthesis of Midshaft Diaphyseal Radius Fractures.

Henry's approach is widely considered the "workhorse" for exposing the volar radius and has not really changed since his original description in 1945. We describe a pronator teres-sparing volar approach to the forearm, for osteosynthesis of midshaft diaphyseal radius fractures. We believe this approach is safe, simple, and reproducible, and has several practical and theoretical advantages over Henry's original description.

A modified ulnar translocation reconstruction technique for Campanacci grade 3 giant cell tumors of the distal radius using a clover leaf plate.

Background: Campanacci grade 3 giant cell tumors of the distal radius are locally aggressive and in close proximity to the median nerve, articular cartilage, flexor and extensor tendons, and the radial artery. Although several reconstructive techniques have been described, it is unclear to what degree these procedures restore function.

Description Of Technique: We present a modified ipsilateral ulna translocation technique using a clover leaf plate, for reconstruction of en bloc resected distal radius.

Repair of the acutely unstable elbow: use of tensionable anchors.

Acute ruptures of the medial or lateral collateral ligaments of the elbow associated with elbow dislocations have traditionally been repaired back to their respective epicondyles using suture anchors or transosseous sutures. Tensioning of those ligaments using conventional techniques had been difficult because of the need to maintain tension while tying and securing sequential knots. Tensionable anchors are a new generation of anchors that have been used for rotator cuff repair, but can be employed for the repair of collateral ligaments and capsular tears.

Imaging recognition of morphological variants at the midcarpal joint.

Purpose: To compare the imaging methods for identifying the various morphological variations of the articular surfaces at the midcarpal joint.

Methods: Thirteen cadaveric wrists were examined by plain neutral anteroposterior radiographs; 2-dimensional computed tomography (CT); 3-dimensional CT reconstruction, and 3-tesla magnetic resonance imaging (MRI). Carpal measurements were performed, and the parameters that defined the scaphoid, lunate, hamate, and capitate morphological types were investigated, with dissection being used as the definitive measure of morphology.

Translunate fracture with associated perilunate injury: 3 case reports with introduction of the translunate arc concept.

We report 3 cases of translunate fractures with associated perilunate dislocations (or subluxation). We believe the translunate injury reflects a higher-velocity trauma and produces further destabilization of the carpus when compared with the established greater and lesser arc injuries. A modification to Johnson's perilunate injury classification system is proposed: the addition of a translunate arc injury subgroup, which would include all perilunate injuries with translunate fractures.

Influence of lunate type on scaphoid kinematics.

Purpose: To assess the influence of lunate type on scaphoid kinematics.

Methods: One hundred normal wrists had fluoroscopic assessment of the wrist in maximal radial, neutral, and ulnar deviation. The shortest distance in a neutral position between the capitate and triquetrum, C-T distance, determined lunate type.
