This study investigated the validity of pulp-to-palm distance measures as clinical indicators of finger flexion capacity. Pulp-to-palm distance and goniometry of the metacarpophalangeal, proximal interphalangeal and distal interphalangeal joints were measured by a single tester in 50 patients with abnormal digital flexion using a computerized hand assessment system. The correlation between pulp-to-palm distance measurements and total finger flexion measures obtained by goniometry, was moderate (r=-0.46 and -0.51). This indicates that the measures are not interchangeable. The relationship between an upper extremity disability score (DASH) and restricted motion was stronger for the goniometric measurements (r=0.45, P<0.01) than for the pulp-to-palm distance measurements (r<0.30, P>0.01). Both types of range of motion measurements were able to discriminate between minimal and substantial upper extremity disability. Further methodological evaluation is required to support the use of pulp-to-palm distance measures as an outcome indicator.

Objective The aim of this study was to report the average tibial plateau angle (TPA) from a large sample of dogs and to determine if breed or gonadectomy had a significant association with abnormal TPA. Study Design This was a retrospective case study. Materials and Methods Medical records from 2006 to 2015 were reviewed for dogs that were diagnosed with cranial cruciate ligament (CrCL) rupture and underwent dynamic surgical stabilization. Signalment, examination findings, preoperative TPA and surgical report were reviewed. Results A total of 3,249 dogs underwent CrCL stabilization surgery from 2006 to 2015. Of the 3,249 dogs, 3,054 dogs met the inclusion criteria for a total of 3,922 stifles to be evaluated. The average preoperative TPA was 29° ± 3.7°. Average breed-specific preoperative TPA ranged from 27° to 35.1°, with four breeds having significantly lesser TPA and four breeds significantly greater TPA than the overall mean of dogs. Neutered dogs had a higher TPA of 28.87° ± 3.8° than non-neutered dogs with an average TPA of 26.88° ± 4.0°, p < 0.001. There was not a significant difference in average TPA between females and males, regardless of the neuter status. Conclusion and Clinical Relevance Our reported preoperative TPA in a large sample of dogs is higher than what has been previously published. In reviewing 3,922 stifles, the average preoperative TPA was 29°. We report the average preoperative TPA in specific breeds and report that neutered dogs have a significantly higher TPA than intact dogs. This updated information may guide clinicians in management decisions regarding treatment for CrCL rupture.
