Osteoid osteoma with an atypical nidus: A case report.

Osteoid osteoma is a benign tumor that can be seen in both cortical or cancellous bone. Radiographic appearance is usually diagnostic. It consists of a small nidus usually less than 1.5cm and a surrounding bony sclerosis. We present one case of osteoid osteoma with an unusual (nearly completely calcified) nidus.

Anterior Cruciate Ligament Reconstruction with Hamstring Tendons Has no Deleterious Effect on Hip Extension Strength.

BACKGROUND: Hamstring tendons are secondary hip extensors. Their harvest for graft in anterior cruciate ligament (ACL) reconstruction may create deleterious effect on hip extension strength. This is of particular importance in sports that need powerful hip extension force like climbing and sprinting. Due to scarcity of a comprehensive study in this area, we designed this prospective study to evaluate hip extension strength following ACL reconstruction using different types of grafts. METHODS: Fifty eight patients were enrolled in this prospective non-randomized case control study to compare isokinetic hip extension strength following ACL reconstruction with different graft types. Twenty patients in group A (both Semitendinosus and Gracilis tendons autograft (ST-G)), 14 patients in group B (Tibialis Posterior tendon allograft (Allograft)), 12 patients in group C (bone-patellar tendon-bone autograft (BPTB)) and 12 patients in group D (only semitendinosus autograft (ST)) were studied. Hip extension strength was tested post-operatively at three- and six-month periods using a Biodex isokinetic testing machine at a speed of 30 degree per second in operated (cases) and non-operated (controls) limbs. RESULTS: There was a significant increase in hip extension force between three and six month intervals in all four groups and in both operated (case) and non-operated (control) limbs (P<0.05, 95% CI). However, there was more increase in case limbs in comparison to control limbs. There was no significant difference in hip extension strength among all four groups (both in case and control limbs) in the third- and the sixth-month post-operative tests. CONCLUSION: Graft type had no effect on hip extension strength following ACL reconstruction, and the harvest of one or both hamstrings had no deleterious effect on hip extension force. LEVEL OF EVIDENCE: III.

Neglected triceps tendon avulsion: case report, literature review, and a new repair method.

Triceps tendon rupture or avulsion is a rare tendon injury. The most common feature of injury is avulsion from osseous insertion on the olecranon. The diagnosis of acute triceps tendon rupture may be missed, and a missed diagnosis can result in prolonged disability and delayed operative management. In this article, we report 2 cases of neglected triceps tendon avulsion and a new V-Y-plasty surgical technique for repair.

An unusual location of ossified intramuscular lipoma: a case report.

Lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. Some studies show that less than 1% of lipomas were ossified. We describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. To the best of the authors' knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and hyperostosis has not been previously reported in the literature.
