Severe calcium pyrophosphate dihydrate deposition disease of the metacarpophalangeal joints.

BMJ Case Rep 2018 Sep 28;2018. Epub 2018 Sep 28.

Medicine/Rheumatology, University of Kentucky, Lexington, Kentucky, USA.

We report a case of calcium pyrophosphate deposition disease (CPPD) with an unusual presentation of severe chondrocalcinosis with atypical large burden deposited in the metacarpophalangeal joints as well as more typical deposition in wrists and knees as demonstrated on plain radiographs. A 77-year-old African-American woman 1-year status post parathyroidectomy for hyperparathyroidism initially presented to the rheumatology clinic to treat suspected rheumatoid arthritis given her pattern of joint involvement but was found to have CPPD. The patient's history is notable for end-stage renal disease which complicates medical management. Read More

Tether Creation Between the Second and Third Extensor Digitorum Communis for Third Extensor Tendon Subluxation at the Metacarpophalangeal Joint.

Tech Hand Up Extrem Surg 2018 Dec;22(4):146-149

Yukioka Hospital Hand Center, Osaka Yukioka College of Health Science, Kita-ku, Osaka-shi, Osaka, Japan.

We developed a substitution technique for a sagittal band reconstruction for subluxation of the third extensor tendon at the metacarpophalangeal joint. Through this procedure, we attempted to supply a tether between the second and third extensor digitorum communis (EDC) tendons. A half-slip of the second EDC was interlaced to the third EDC tendon at the level of the third metacarpal head with the metacarpophalangeal joint in full flexion position; this ensured that the interlace of the graft serves as a direct stabilizer against ulnar subluxation.

F-sodium fluoride positron emission tomography of the racing Thoroughbred fetlock: Validation and comparison with other imaging modalities in nine horses.

Equine Vet J 2018 Sep 14. Epub 2018 Sep 14.

School of Veterinary Medicine, University of California, Davis, California, USA.

Background: Early and accurate detection of stress remodelling in racehorses is of utmost importance to prevent catastrophic injuries. Current imaging techniques have limitations in assessing early changes predisposing to catastrophic breakdowns. Positron emission tomography (PET) using F-sodium fluoride ( F-NaF) is a sensitive method for the detection of early bone turnover and may improve early recognition of subtle injuries. Read More

Normal force distribution and posture of a hand pressing on a flat surface.

J Biomech 2018 Oct 15;79:164-172. Epub 2018 Aug 15.

Department of Industrial and Operations Engineering, University of Michigan, Ann Arbor, MI, United States.

Hand strength data are needed to understand and predict hand postures and finger loads while placing the hand on an object or surface. This study aims to analyze the effect of hand posture and surface orientation on hand force while pressing a flat surface. Twelve participants, 6 females and 6 males ages 19-25, performed three exertions (100%, 30% and 10% MVC- Maximum Voluntary Contraction) perpendicular to a plate in 4 angles (-45°, 0°, 45° and 90° with respect to the horizontal plane) at elbow height.
