Patients treated by the proposed ACL reconstruction technique showed on average good to excellent long-term results. A meniscal lesion at the time of ACL tear was highly predictive for less favourable outcome.
There was no significant OA progression on plain radiography at an average of 11 years post-HA. Sound indication criteria is essential, as 45% of patients required subsequent surgery.
We retrospectively reviewed the safety and efficacy of operative treatment of torsional malalignment of the tibia in 44 children, on whom we performed 71 derotational osteotomies of the distal tibia to treat tibial torsion. We placed four pins using an alignment jig, performed a percutaneous osteotomy, and applied an external fixator after derotation. Postoperative radiographs showed accurate tibial derotation and pin placement in all patients. Nine patients developed superficial pin-tract infections that resolved with antibiotic treatment. Two developed fractures after removal of the external fixator, which healed in a plaster cast. Operative treatment of these cases with an external fixator is safe, effective, and well tolerated.
Case:
Osteochondral shearing fracture of the humeral head after an anterior shoulder dislocation is a condition that has rarely been reported in literature. We report a case of a large posteriorly located fragment of such a fracture in a 23-year-old man. We performed open reduction and internal fixation with resorbable pins through a deltopectoral approach and subscapularis tenotomy.
Conclusion:
In our case of a large osteochondral fracture of the posterior humeral head, treatment by open reduction and internal fixation showed an excellent radiographic result at 1 year and clinical result up to 5 years postoperatively.
Bei der Hoffa-Fraktur handelt es sich um eine intraartikuläre koronare Fraktur des distalen Femurs. Die Erstbeschreibung dieser Fraktur geht auf Friedrich Bush aus dem Jahr 1869 zurück, Albert Hoffa beschrieb die nach ihm benannte Fraktur offiziell 1904. Sie ist in über 80 % der Fälle mit Hochrasanztraumata mit axialer Krafteinwirkung auf das flektierte Kniegelenk assoziiert [1]. Ausserdem ist die Hoffa-Fraktur bei Sturz aus grosser Höhe und bei Sportarten mit Rotationsbewegungen und gleichzeitig axialer Krafteinwirkung auf das flektierte Kniegelenk beschrieben. Die Hoffa-Fraktur in Kombination mit einer Patellaluxation ist eine Rarität; weltweit gibt es nur einzelne Fallberichte. Die Klassifikation nach der AO (Arbeitsgemeinschaft für Osteosynthesefragen) beschreibt die Hoffa-Fraktur als eine 33-B3-Verletzung. Diese kann nach Letenneur näher klassifiziert werden (Typ I bis Typ III).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
