Halicephalobus gingivalis is a free-living nematode that occasionally causes infections in horses. We report a rare case of limb fracture of horse caused by infection with H. gingivalis. An 8-year-old mare was referred to the Veterinary Hospital of the Federal University of Lavras with claudication grade 5 of the right hind limb, that had been started 3 months ago. The patient had aseptic arthritis in the tarsal joint and edema that extended to the quartile. The radiographic examination showed punctate osteolysis with exacerbation of bone trabeculation along the calcaneus, talus, proximal epiphysis of the third metatarsal and distal epiphysis of the tibia. Treatment for arthritis was initiated, and the animal showed a slight improvement in limb function. However, 21 days after hospitalization, due to a comminuted fracture of the tibia, it was euthanized. At necropsy, yellowish masses were found from the metatarsal to the tibia, and around the tarsal bones and joint. Similar masses were also found in the left kidney. Numerous nematodes compatible with H. gingivalis were identified. This is the first description of a pathological fracture caused by H. gingivalis infection in an equine limb.

Developmental dysplasia of the hip is a condition characterized by hip joint instability due to acetabular dysplasia in infancy, necessitating precise ultrasound examination. Legg-Calvé-Perthes disease is caused by a temporary disruption in blood flow to the femoral head during childhood, progressing through avascular, fragmentation, re-ossification, and residual stages. Slipped capital femoral epiphysis is a condition where the femoral head shifts medially along the epiphyseal line during adolescence due to stress, such as weight-bearing. Differentiating between transient hip synovitis and septic arthritis may require joint fluid aspiration. Osteomyelitis can be associated with soft tissue edema and osteolysis. When multiple lesions are present, it is essential to distinguish between Langerhans cell histiocytosis and metastatic neuroblastoma. This review will introduce imaging techniques and typical findings for these conditions.

Developmental dysplasia or dislocation of the hip is the most pronounced form of a condition in which the femoral heads tends progressively to leave the acetabulum. In the young child the variability of findings and course suggest a spectrum of conditions in which there are a number of common features: restriction of movement, particularly of abduction in flexion; shortening; and abnormal radiology, including a sloping or dysplastic acetabulum and delay in the appearance of the upper femoral epiphysis. It is vital to make the diagnosis of a congenital dislocation as soon after birth as possible. Conservative treatment with an abduction brace before the child run begins to walk is completely adequate, but after the age of 4 even surgical repositioning is difficult and after the age of 7 it is almost impossible. The aim of the study was to gain insight into the value of physical therapy of developmental dysplasia or dislocation after operation.

The adolescent Tillaux fracture is an avulsion fracture of the anterolateral corner of the distal tibial epiphysis caused by external rotation of the foot. This type of fracture occurs during epiphyseal fusion in adolescence. A difficult to detect Tillaux fracture was discovered on a preoperative radiograph, such fractures have rarely been reported to accompany a predominantly adult-type ankle fracture. Especially, to the best of our knowledge, no case of a trimalleolar ankle fracture in an adolescent with a Tillaux fracture has been reported. Thus, we present a case of a trimalleolar ankle fracture in a 15-year-old adolescent with a Tillaux fracture who was successfully treated surgically.

The giant cell tumor comprises approximately 5% of all bone tumors especially in the long tubular bones, particularly in proximity to the epiphysis. A rare case of giant cell tumor involving the patella was recently experienced by authors. Case summary with brief review of reference is presented.

An intraosseous ganglion typically exists in periarticular epiphysis or subchondral area, and is usually treated with open curettage of cyst or curettage and bone graft. We report a case of intraosseous ganglion of talus treated by endoscopic curettage and bone grafting with a review of the literature.

The growth effects of newly developed recombinant human growth hormone (rHGH), were compared with those of Biotropine. For the effective evaluation, we examined the increasing rate of body weight and the thickness of tibial epiphysis as criteria of growth effects on hypophysectomised female rats treated with varing concentration of rHGH for 4 days. rHGH treated groups showed significant body weight gain which was less evident in Biotropine and vehicle treatment group. In tibial epiphyseal test, rHGH also showed clear effects compared to Biotropine and vehicle treatment group. Above findings indicate that newly developed rHGH has better effects of growth stimulation on female rats than Biotropine does.

Multiple epiphyseal dysplasia is an uncommon disorder, which was first described by Fairbank in 1935, characterized by irregularity in development of the epiphysis that manifests itself as late appearance and mottling of the ossification centers, knobby joints, stubby digits and minimal shortness of stature. It is typically transmitted as an autosomal dominant trait though recessive forms have been described. The diagnosis is established on the basis of the positive roentgenographic findings in combination with the absence of biochemical abnormalities. We report a case of multiple epiphyseal dysplasia, which was improved by herbal medication.

Giant cell tumor of bone is relatively common neoplasm usually involving epiphysis of long bone. And rarely it involves the diaphysis or metaphysis without epiphyseal extension. We report on an 18-year-old girl with giant cell tumor of ulnar diaphysis. She was treated with wide excision and reconstuction with nonvascularized autogenous fibular graft. We harvested fibular fragment preserving fibular continuity to reduce donor site morbidity. Surgical outcome and functional result was excellent.

Purpose: We examined the kinematics and kinetics of the shoulder in youth baseball pitchers in light of the mechanisms of development of little league shoulder and humeral retrotorsion. Materials and Methods: The joint kinematics and the net force and torque acting on the humerus were calculated in fourteen youth pitchers throwing in a simulated game. Results: The major force component acting on the humerus was a tensile force of 378$\pm$81 N that peaked just after ball release. The predominant torque on the humerus was an external rotation torque about the long axis of the humerus. This torque reached a peak value of 35.3$\pm$6.7 Nm about 73$\%$through the pitching motion. This torque is approximately 66$\%$ of the torque required to fracture of the adult humerus. Conclusions: The direction of the humeral torque was consistent with the development of increased humeral retrotorsion in the throwing arm. Shear stress arising from the high torque during the late cocking phase likely leads to deformation the relatively weak proximal humeral epiphysis. The external rotation torque applied to the humerus during the pitch also agrees with the proposed mechanism for development little league shoulder, which has been hypothesized to be due to rotational stresses acting on the epiphysis during the throwing motion.
