Intraaticular treatment of tarsal degenerative joint disease in cattle.

Tarsal degenerative joint disease (DJD) in 12 cattle was classified as primary or secondary, based on age, evidence of hereditary or congenital joint conformation defects, faulty hindlimb alignment, duration and type of usage joints were subjected to, and history or signs of repeated trauma. Three of the cattle had bilateral primary tarsal DJD, 7 had bilateral secondary tarsal DJD, and 2 had secondary DJD of the left tarsus. Analyses of synovial fluid samples provided a means of characterizing pathologic changes of tarsal DJD, Results of blood and synovial fluid analyses were grouped in compilation of data for cattle affected with either primary or secondary tarsal DJD. Corticosteroids and a long-acting synthetic progestational agent were injected singly or in combination with aqueous antibiotics into affected tarsal joints. Tarsal joints of 5 of the cattle responded favorably to a single intraarticular treatment, as manifested by palliative relief and functionally usable joints. Seven joints of 5 cattle were subjected to repeated intraarticular treatment. Serial synovial fluid analyses in 7 of the cattle provided a means of assessing tarsal joint response to intraarticular treatment or to therapeutic arthrocentesis, exclusive of patient objective response. One cow developed a mild self-limiting bilateral postinjection synovitis that was resolved after the 2nd and final intraarticular injection. Usable function returned to tarsal joints of cattle that responded favorably to intraarticular treatment at different periods after single or repeated injections. Three cattle with advanced tarsal DJD experienced minor temporary relief and were euthanatized at their owner's request. Improvement did not occur in the tarsal joint of 1 cow subjected to therapeutic aspiration only. Intraarticular treatment in all cattle was considered supportive to the animal's well-being rather than curative.

Bone dysplasias in the labrador retriever: a radiographic study.

A radiographic study of the humeral head, elbow joint, hip joint, stifle joint, tarsal joint, and lumbosacral (LS) junction was performed in 1,018 Labrador retrievers in search for humeral head, femoral condyle, and tarsal osteochondroses; elbow and hip dysplasias; and transitional LS vertebrae. The ages of all dogs reported were one year or older. Elbow dysplasia was detected as the most common lesion (17.8%), with a higher prevalence in the male dog. Hip dysplasia was the second most common lesion (12.6%) and was found equally in the male and female. Elbows and hips were often affected in the same dog (4.2%). Transitional vertebral segments were found more frequently in the female (4.2%) than in the male (1.0%), and the condition was thought to be inherited.

Postural development in school children: a cross-sectional study.

BACKGROUND: Little information on quantitative sagittal plane postural alignment and evolution in children exists. The objectives of this study are to document the evolution of upright, static, sagittal posture in children and to identify possible critical phases of postural evolution (maturation). METHODS: A total of 1084 children (aged 4-12 years) received a sagittal postural evaluation with the Biotonix postural analysis system. Data were retrieved from the Biotonix internet database. Children were stratified and analyzed by years of age with n = 36 in the youngest age group (4 years) and n = 184 in the oldest age group (12 years). Children were analyzed in the neutral upright posture. Variables measured were sagittal translation distances in millimeters of: the knee relative to the tarsal joint, pelvis relative to the tarsal joint, shoulder relative to the tarsal joint, and head relative to the tarsal joint. A two-way factorial ANOVA was used to test for age and gender effects on posture, while polynomial trend analyses were used to test for increased postural displacements with years of age. RESULTS: Two-way ANOVA yielded a significant main effect of age for all 4 sagittal postural variables and gender for all variables except head translation. No age x gender interaction was found. Polynomial trend analyses showed a significant linear association between child age and all four postural variables: anterior head translation (p < 0.001), anterior shoulder translation (p < 0.001), anterior pelvic translation (p < 0.001), anterior knee translation (p < 0.001). Between the ages of 11 and 12 years, for anterior knee translation, T-test post hoc analysis revealed only one significant rough break in the continuity of the age related trend. CONCLUSION: A significant linear trend for increasing sagittal plane postural translations of the head, thorax, pelvis, and knee was found as children age from 4 years to 12 years. These postural translations provide preliminary normative data for the alignment of a child's sagittal plane posture.

Characteristics of normal equine tarsal synovial fluid.

Physical, biochemical, and cytologic properties of synovial fluid from normal equine tarsal joints were investigated. Tarsal synovial fluid was pale yellow, clear, free of flocculent material, and did not clot. Volume varied in direct proportion to individual tarsal joint size. Relative viscosity was related to volume, polymerization and quantity of hyaluronic acid, and protein concentration. Mucinous precipitate quality (hyaluronic acid polymerization) was uniformly high. Results of certain analyses of serum were compared with those of tarsal synovial fluid. Tarsal synovial fluid protein concentration was low in conjunction with a high A:G ratio. Serum: synovial fluid sugar ratio was 1.24:1. Serum ALP, ACP, LDH, GOT, and GPT activity levels were higher than their corresponding levels of activity in tarsal synovial fluid. Serum ALD activity level was slightly lower than its tarsal synovial fluid counterpart. Total erythrocyte counts ranged markedly, while total leukocyte counts were uniform and low. Lymphocytes were the predominant synovial fluid cell type.

Kinematics of the hind limb in trotting horses after induced lameness of the distal intertarsal and tarsometatarsal joints and intra-articular administration of anesthetic.

OBJECTIVE: To identify hind limb and pelvic kinematic variables that change in trotting horses after induced lameness of the distal intertarsal and tarsometatarsal joints and after subsequent intra-articular administration of anesthetic. ANIMALS: 8 clinically normal adult horses. PROCEDURE: Kinematic measurements were made before and after transient endotoxin-induced lameness of the distal intertarsal and tarsometatarsal joints and after intra-articular administration of anesthetic. Fourteen displacement and joint angle (metatarsophalangeal [fetlock] and tarsal joints) measurements were made on the right hind limb, sacrum, and the right and left tubera coxae. Kinematic measurements were compared by general linear models, using a repeated measures ANOVA. Post hoc multiple comparisons between treatments were evaluated with a Fisher least squared difference test at alpha = 0.05. RESULTS: After lameness induction, fetlock and tarsal joint extension during stance decreased, fetlock joint flexion and hoof height during swing increased, limb protraction decreased, and vertical excursion of the tubera coxae became more asymmetric. After intra-articular administration of anesthetic, limb protraction returned to the degree seen before lameness, and vertical excursion of the tubera coxae became more symmetric. CONCLUSIONS AND CLINICAL RELEVANCE: Increased length of hind limb protraction and symmetry of tubera coxae vertical excursion are sensitive indicators of improvement in tarsal joint lameness. When evaluating changes in tarsal joint lameness, evaluating the horse from the side (to assess limb protraction) is as important as evaluating from the rear (to assess pelvic symmetry).

Intertarsal ligaments: high resolution MRI and anatomic correlation.

High resolution MRI was performed on four cadaveric foot specimens of human feet to demonstrate the ligaments of the tarsal joints. Spin echo T1 images were obtained using a local gradient coil that produces 6 G/cm and 100 A in all three axes. The best views for each of the individual ligaments were determined. High resolution MRI potentially can demonstrate most of the intertarsal ligaments.

Comparison of two methods of joint distraction for arthrodesis of the foot.

A study was conducted to compare the efficacy of two methods of obtaining the joint exposure needed to perform arthrodesis or exploration of various joints of the foot. The investigation was performed by means of simulated arthrodesis in a cadaveric model. On each specimen, a single investigator performed standard incisions and dissection as typically performed for surgical arthrodesis of the first metatarsocuneiform, naviculocuneiform, medial intercuneiform, talonavicular, calcaneocuboid, and subtalar joints. Each joint was exposed and distracted once using the Tarsal Joint Distractor (Orthovation LLC, Sealy, Texas) and once using the Inge Laminar Spreader (K-Medic, Northvale, New Jersey). While a given joint was distracted, a calibrated digital photograph of the exposed joint was taken from an angle best representing the surgeon's view of the articular space. Digital images were analyzed to calculate the maximum distance between articular surfaces and the total area of articular surfaces exposed while distracted. Thirty-six joints involving six feet were distracted using each device. The mean area of articular exposure was 178.3 mm(2) for the Tarsal Joint Distractor and 116.4 mm(2) for the Inge Laminar Spreader (P = .0001). The mean distance of distraction was 8.1 mm for the Tarsal Joint Distractor and 6.5 mm for the Inge Laminar Spreader (P = .0001). An average of 53.1% more exposure and 25.2% more distance between distracted surfaces was achieved when using the Tarsal Joint Distractor. The Tarsal Joint Distractor provides significantly better visualization of articular spaces typical of midfoot and rearfoot arthrodesis procedures than the Inge Laminar Spreader.

Tarsal degenerative joint disease in cattle: blood and synovial fluid changes.

Tarsal degenerative joint disease (DJD) in 27 cattle was classified as primary or secondary based on age, joint conformation defects, faulty hindlimb alignment, or history of trauma to the affected joint(s). Results of blood and synovial fluid analysis for cattle affected with primary or secondary tarsal DJD were grouped in compilation of data. Cattle with tarsal DJD had significantly (P smaller than 0.01) reduced hemoglobin (Hb) content in comparison to that in control cattle. There was highly significant (P smaller than 0.001) reduction in packed cell volume (PCV). A significant difference was not determined for mean corpuscular hemoglobin concentration (MCHC) values of the 2 groups of cattle. Total white blood cell (WBC) counts closely paralleled each other, although mean proportion of neutrophils was significantly (P smaller than 0.05) greater in cattle affected with tarsal DJD, as were mean proportion of lymphocytes (P smaller than 0.02). Synovial fluid samples were analyzed for physical, biochemical, and cytologic properties. Statistical comparisons were made between values determined for arthritic cattle and control cattle. All samples from cattle with tarsal DJD were transudative. Opacity and flocculation were attributed to the presence of cartilaginous fragments and fibrils. There was significant correlation between increased relative viscosity (RV) and higher grades of mucinous precipitate quality (MPQ; r = +0.294, P smaller than 0.05) for all cattle. Mean alkaline phosphatase (ALP) activity for arthritic cattle was significantly (P smaller than 0.001) reduced, as was the mean activity for lactic dehydrogenase (LDH; P smaller than 0.05). The mean aldolase (ALD) activity for arthritic cattle was increased, whereas mean activity values for glutamic oxalacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were reduced. Samples from arthritic cattle had reduced total leukocyte counts and significantly (P smaller than 0.05) increased proportion of macrophages in comparison to the values in control cattle.
