The histologic and histochemical features of quinolone-induced arthropathy were studied using 14 skeletally immature Beagle dogs (3 to 4 months old) dosed orally with difloxacin at 300 mg/kg body weight once daily for 1, 2, 5, or 7 days. A placebo was given to eight other age-matched Beagle dogs that served as controls. A scoring technique that included lesion size and histologic features was u...

OBJECTIVE To evaluate T2 relaxation time change using axial T2 mapping in a rabbit degenerated disc model and determine the most correlated variable with histologic score among T2 relaxation time, disc height index, and Pfirrmann grade. MATERIALS AND METHODS Degenerated disc model was made in 4 lumbar discs of 11 rabbits (n = 44) by percutaneous annular puncture with various severities of an ...

Background: Meniscus tissue is highly susceptible to injury and tears. As these are intrasynovial and lack cellularity, their healing potential is less. Any knowledge to the factors affecting the meniscal healing can help surgeons in treating meniscal injuries. Hypothesis: Patient age is a predictor of the healing of meniscus tissue. Study Design: Prospective study. Methods: Gross and histologi...

background: a potential specific problem of patellar tendon graft in acl reconstruction is the possibility of graft-tunnel mismatch which could be more problematic with anatomic acl reconstruction where the femoral tunnel is placed low on the lateral wall of the lateral femoral condyle. the occasional occurrence of this mismatch raises the question that whether a correlation exists between pati...

BACKGROUND Postoperative asymptomatic deep venous thromboses (ADVT) can give rise to posttthrombotic syndrome (PTS), but there are still many unresolved issues in this context. For example, there is a lack of knowledge regarding the fate of small ADVT following minor orthopedic surgery. This follow-up study evaluates postthrombotic changes and clinical manifestations of PTS in a group of patien...

CONTEXT LigaSure™ is considered safe in performing pancreaticoduodenectomy (PD). However, no data are available regarding the possible damage of tissues at the resection margins and the impact thereof on histologic margin assessment. OBJECTIVE This study compares the degree of histologic damage to the resection margins when using LigaSure™ (Group 1) or traditional ligature (Group 2). METHOD...

background: palmaris longus (pl) is a muscle with marked variations. it is harvested as a tendon graft in many surgical proceduresin which a certain length of tendon is required. the aims of the present study were to determine the variations of this tendon in iranian population and to find whether the length of pl tendon could be estimated by measuring the forearm length and height.   methods: ...
