Reliability and validity of grip and pinch strength evaluations

Abstract: Twenty-seven college women participated in a study to evaluate the reliability and validity of four tests of hand strength: grip, palmar pinch, key pinch, and tip pinch. Standardized positioning and instructions were followed. The results showed very high inter-rater reliability. Test-retest reliability was highest in all tests when the mean of three trials was used. Lower correlations were shown when one trial or the highest score of three trials were utilized. The Jamar dynamometer by Asimow Engineering and the pinch gauge by B&L Engineering demonstrated the highest accuracy of the instruments tested.

Latent Class Analysis

Abstract: c ( l WHEN RADIOGRAPHS ARE normal in a young adult patient with snuffbox tenderness after a fall, we turn to more sophisticated radiological examination to rule out a fracture of the scaphoid. But each examination can miss a fracture or suggest a fracture when one is not present. There is no test that is both reliable and accurate in the diagnosis of a scaphoid fracture among patients with a suspected fracture. Both patients and health providers crave certainty, but we can only estimate the probability of a scaphoid fracture in this context. This situation is not unique. The diagnosis of carpal tunnel syndrome, compartment syndrome, and prosthetic joint infection, to name a few examples, are all probabilities rather than certainties. The basic issue is that there is no valid and reliable test that can make the diagnosis with certainty. Such a test is referred to as the gold or reference standard. When there is a reference standard, the value of a diagnostic test is evaluated using diagnostic performance characteristics such as sensitivity, specificity, and positive and negative predictive values. In the absence of a reference standard, an increasingly used statistical method is latent class analysis (LCA), which identifies unobserved (or latent) associations of risk factors that estimate the probability of disease. For instance, in the setting of a suspected scaphoid fracture, 1 study estimated that the presence of all 4 of the identified risk factors (male sex, sports injury, anatomical snuffbox tenderness on ulnar deviation of the wrist within 72 hours, and thumb-index finger pinch) was associated with a 74% probability of scaphoid fracture. Other studies used LCA and conventional methods to calculate diagnostic performance characteristics and

Triangular fibrocartilage complex lesions: A classification

Abstract: Based on anatomic and biomechanical studies and review of our clinical experience of the past 10 years, a classification of injuries to the triangular fibrocartilage complex is presented. This classification is based on the clinical examination, routine x-ray films, wrist arthrograms, wrist arthroscopy, and wrist arthrotomy. The classification recognizes both traumatic and degenerative lesions. Traumatic lesions are classified according to their location. Degenerative lesions are classified by the location and severity of degenerative changes of the triangular fibrocartilage complex, ulnar head, ulnocarpal bones and lunotriquetral ligament.

The SLAC wrist : Scapholunate advanced collapse pattern of degenerative arthritis

Abstract: Four thousand wrist x-ray films were reviewed to establish the pattern of sequential changes in degenerative arthritis of the wrist. After eliminating all other arthritides, we studied 210 cases of degenerative arthritis. The most common pattern (57%) was arthritis between the scaphoid, lunate, and radius; 27% of cases occurred between the scaphoid, trapezium, and trapezoid; a combination of these two patterns occurred in 15%. Twenty operations were performed on 19 patients with the scapholunate advanced collapse pattern. Eighteen of 19 patients had less pain postoperatively and none required pain medication. Flexion-extension and radial-ulnar deviation motions showed considerable improvement after the operation.

The triangular fibrocartilage complex of the wrist-Anatomy and function

Abstract: The anatomy and function of the triangular fibrocartilage complex (TFCC) of the wrist was studied through anatomic dissections and biomechanical testing of 61 specimens. The TFCC was found to be a homogenous structure composed of but not dissectable into, the articular disc, the dorsal and volar radioulnar ligaments, the meniscus homologue, the ulnar collateral ligament, and the sheath of the extensor carpi ulnaris. The TFCC tivas found to be perforated in 53% of specimens dissected, and all of the wrists with a demonstrable perforation showed evidence of damage or erosion of the cartilage of the Innate and/or distal ulna. Biomechanical studies suggest that the TFCC functions both as a cushion for the ulnar carpus and as a major stabilizer of the distal radioulnar joint. Perforations of the TFCC can result in the ulna-lunate abutment and cartilage erosion. Since excision of the TFCC stay lead to ulnolunatc abutment, chronic wrist pain, and/or instability of the distal radioulnar joint, it is not recommended.
