Clinical and radiographic changes of carpi, tarsi and interphalangeal joints of beef zebu bulls on semen collection regimen / Mudanças clínicas e radiográficas das articulações carpo, tarso e interfalangeana de touros de corte zebuínos em regime de colheita de sêmen

Osteoarthritis and osteochondrosis are highly correlated to reproductive failure in bulls. This study aimed to evaluate the carpal, tarsal and interphalangeal lesions in beef zebu bulls on semen collection regimen. Twenty-one beef cattle bulls, in a total of forty-one animals, were split into three age-based groups: animals from two to four years old (GI), from more than four to eight years old (GII) and above eight years old (GIII). The clinical findings were conformational changes of limbs, synovial effusion, peripheral venous engorgement of joints and prolonged decubitus. The total population showed moderate clinical manifestation and radiographic score. The GIII presented more severe joint lesions. Carpi and tarsi regions had discrete to difuse osteophytosis, subchondral cysts, cartilaginous flaps, bone incongruence and fragmentation, osteitis, and ankylosis. Interphalangeal joints presented osteophytosis, distal phalanx osteitis and enthesophytosis. The digital radiographic examination allowed full identification of articular lesions and their clinical correspondences, besides the positive correlation between age, body weight and radiographic score.(AU)

Osteoartrite e osteocondrose estão altamente correlacionados à falha reprodutiva em touros. Este estudo teve como objetivo avaliar as lesões do carpo, tarso e interfalangianas em touros zebuínos de corte em regime de coleta de sêmen. Vinte e um bovinos de corte, touros, provenientes de um total de 41 animais, foram divididos em três grupos baseados na idade, sendo eles: animais de dois a quatro anos (GI), de mais de quatro a oito anos (GII) e acima de oito anos de idade (GIII). Os sinais clínicos encontrados foram mudanças de conformação dos membros, derrame sinovial, ingurgitamento venoso periférico das articulações e decúbito prolongado. A população total avaliada apresentou manifestação clínica e escore radiográfico de grau moderado. Os touros mais velhos apresentaram maior gravidade nas lesões articulares. O GIII foi o que apresentou as lesões articulares mais severas. Identificou-se nos carpos osteofitose de discreta a difusa, cistos subcondrais, "flaps" cartilaginosos, fragmentação óssea, perda de congruência óssea, osteíte e anquilose; as lesões társicas obedeceram ao mesmo padrão. As articulações interfalangeanas apresentaram somente osteofitose, osteíte nas falanges distais e entesiofitose. O exame radiográfico digital permitiu a identificação completa das lesões articulares e suas correspondências clínicas, além da correlação positiva entre a idade, o peso corporal e o escore radiológico.(AU)

Arthrodesis of Distal Interphalangeal Joints in the Hand with Interosseous Wiring and Intramedullary K-wire Fixation

BACKGROUND: To evaluate the efficacy of intramedullary K-wire fixation and interosseous wiring in the arthrodesis of the distal interphalangeal (DIP) joint with description of surgical procedure. METHODS: We retrospectively analyzed 9 cases (7 women and 2 men) of DIP joint arthrodesis. The average age of patients was 44.2 years (range, 21 to 71 years) and the mean follow-up period was 19.6 months. Joint union was evaluated on the follow-up radiographs together with postoperative complications. RESULTS: All cases achieved radiologic union of the arthrodesis site. There was no surgical complication except for one case of skin irritation by the interosseous wire knot which was removed during the follow-up period. CONCLUSIONS: Intramedullary K-wire fixation and interosseous wiring could be an alternative procedure of arthrodesis in the DIP joint.

Kirner's deformity misdiagnosed as fracture: a case report

Kirner's deformity or dystelephalangy is a rare entity which presents with painless, progressive, bilateral radiovolar curving of the terminal phalanges of the little fingers. It is a clinicoradiological diagnosis. Herein, we present a case where the patient was being treated as having a fracture of the distal phalanx because of misdiagnosis of Kirner's deformity. Given the rarity of the deformity, we believe it useful to present our case report as a contribution to the literature

Correlation of Anti-Cyclic Citrullinated Antibody with Hand Joint Erosion Score in Rheumatoid Arthritis Patients

BACKGROUND/AIMS: To examine the correlation between radiological joint damage and serological parameters in early rheumatoid arthritis (RA). METHODS: This retrospective study reviewed the records of 216 patients diagnosed with RA and classified them according to disease duration: group 1, 24 months; and group 3, all patients combined. The extent of joint damage was assessed from plain radiographs using a modified version of the Larsen method and compared among groups. RESULTS: The mean radiographic joint damage score was significantly higher in patients who had established RA (10.1 points) compared with those who had early RA. In group 1, the inflammatory parameters, erythrocyte sedimentation rate, and C-reactive protein were positively correlated with the joint damage score, but rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibody were not. A subgroup analysis revealed that the anti-CCP positive patients in groups 1 and 2 had greater joint damage scores than did the anti-CCP negative patients, but no difference in RF was observed between subgroups. Anti-CCP positivity was not significantly correlated with joint damage sores in group 3. CONCLUSIONS: Anti-CCP positivity was significantly correlated with more severe joint damage at diagnosis. A correlation was observed between the radiological joint damage score and inflammatory parameters in early and established RA, indicating that anti-CCP can serve as a diagnostic tool and predict structural joint damage. These findings suggest anti-CCP positive patients should receive aggressive therapeutic intervention.

Roentgenographic evaluation of erosive changes in early cases of rheumatoid arthritis: using magnified view.

The diagnosis of typical cases of rheumatoid arthritis can be done on clinical grounds but problem arises in equivocal cases and radiological changes suggestive of rheumatoid arthritis help in confirmation or overweight the clinical diagnosis. Radiological changes viz, osteoporosis and soft tissue swelling can be assessed by conventional projections but problem arises in early detection of minute erosive changes of the articular surfaces. These lesions have been very well demonstrated by using magnification radiography and hence may be recommended for early diagnosis of rheumatoid arthritis.
