Periprosthetic pathologic fracture following tibial Echinoccocosis: A case report.

ABSTRACT: INTRODUCTION:Hydatid disease in humans caused by the parasitic tapeworm Echinococcus granulosus has an osseous involvement of about 0.5%-2.5% of all cases in humans. The location of hydatid cysts in the tibia is seldom described in the medical literature, and its diagnosis and treatment is challenging. CASE REPORT:This paper presents a patient, with a long term, well tolerated, bilateral total knee arthroplasty (TKA), treated at our clinic, with a recent history of pain and oedema in her left upper leg. After achieving a, radiologically and histhopathologically, well documented, diagnosis of Echinoccocosis lesion in her left proximal tibia, a surgical intervention was planed, a wide resection of the cyst performed, and a specific anti-helmintic therapy was instituted. Four years later, she returns to our observation complaining of pain and unable to bear weight on her left knee, from which a pathologic fracture, adjacent to the tibial component, was diagnosed. After surgical debridement of the newly advanced hydatid cyst growth, the TKA was revised, and due to the tibial component failure and the femoral implant loosening, a semi-constrained total knee revision arthroplasty was executed. Functional outcome was excellent. CONCLUSION:Although challenges in treatment of musculoskeletal hydatid cysts (HC) lesions have been documented, data regarding the musculoskeletal HC lesions resembling tumor is scarce, and those resulting in a prosthetic failure have not been published. The authors intend to add data concerning the therapeutic approach to this entity.

Project description:Introduction and importance: Unicondylar tibial plateau fractures with tibial shaft fractures are extremely rare among the elderly group of people. The traditional treatment method is to apply double plates to fix unicondylar tibial plateau fractures combined with tibial shaft fractures respectively, but this fixation method can disrupt the blood supply around the soft tissues and increase the rate of postoperative infection and fracture non-union. In this paper, we would analyse an old unicondylar tibial plateau fracture (Schatzker type III) with tibial shaft fracture which admitted to our department and discussed the efficacy of using intramedullary nails and plates in the treatment of these fractures. Case presentation A 78-year-old woman with an old unicondylar tibial plateau fracture combined with tibial shaft fracture was presented in this case. Using an intramedullary nail combined with a plate to achieve good results. Clinical discussion This case represents a rare case of an unicondylar tibial plateau fracture with a tibial shaft fracture. In this case, the tibial plateau fracture was first incised and internally fixed with a 9-hole plate across the fracture line of the tibial shaft, followed by fixing the tibial shaft fracture with an intramedullary nail. This treatment helped us successfully reset the unicondylar tibial plateau fracture with tibial shaft fracture and provided a satisfactory outcome for the patient. Conclusion Using intramedullary nails combined with plates to treat unicondylar tibial plateau fractures with tibial shaft fractures allowed for a predictable healing result. Highlights • Unicondylar tibial plateau fractures with tibial shaft fractures are extremely rare in the elderly.• Traditional double plate internal fixation seriously affected soft tissue and bone healing.• The use of plates in combination with intramedullary nails can reduce the destruction of soft tissue and fix both the tibial plateau and the tibial shaft.

Project description:In the treatment of Gustilo Type 3B open tibial fractures, it is important to perform soft tissue reconstruction and bone reconstruction simultaneously. Gastrocnemius muscle and soleus muscle flaps are generally used as rotational flaps for the tibia. The distal third of the tibia can often not be covered with the gastrocnemius muscle and soleus muscle flaps. Treatment distal to the distal third of the tibia is difficult because fewer flap options are available. In the present report, we describe our experience with a Gustilo Type 3B open tibial fracture treated by gastrocnemius muscle and soleus muscle flaps, along with an additional proximally based flexor hallucis longus flap, which is a rare procedure.The participant was a 17-year-old male who injured his left tibia in a motorcycle traffic accident. Physical examination revealed a wound of 13 cm × 7 cm extending from the medial lower leg to the posterior aspect, with extensive skin loss. There was no nerve or vascular injury. The tibia was exposed, with detachment of the periosteum. The radiograph revealed a tibial shaft fracture. The AO/OTA classification was 42-A3.3, and it was classified as a Gustilo-Anderson Type 3B fracture. Gastrocnemius muscle and soleus muscle flaps were lifted in the area of the soft-tissue defect and then, placed over the tibia. Despite this, the distal portion of the tibia remained uncovered. Therefore, a flexor hallucis longus flap was lifted and placed over the distal portion of the tibia. On day 7 after the injury, the external fixation device was removed and the tibial shaft was fixated with two Ender nails (4.5 mm in diameter). The clinical course was satisfactory, and the skin graft and flap were successful. Bone union was achieved without infection, and the resulting range of motion was normal.For the treatment of Gustilo-Anderson Type 3B open tibial fractures, early treatment of the soft-tissue defect is vital. We surgically treated a Gustilo-Anderson Type 3B open tibial fracture with gastrocnemius muscle and soleus muscle flaps, along with an additional proximally based flexor hallucis longus flap, which is a rare procedure. In the event of a soft-tissue defect in the distal third of the tibia, the use of a proximally based flexor hallucis longus flap is an effective surgical approach.
