Poor prognosis and complications are common in limb salvage surgery for malignant tumors of the proximal tibia invading the fibula.
Malignant tumors in proximal tibia invading fibula usually have a large tumor volume and are adjacent to the neurovascular bundles. The prognoses and functional outcomes of limb salvage for these patients are uncertain. We, therefore, asked whether patients with limb salvage surgery for malignant tumors in proximal tibia invading fibula had poorer oncological prognosis, higher complication rate, and lower postoperative functional score compared with patients without fibula invasion. ⋯ Patients with limb salvage surgery for malignant tumors in proximal tibia invading fibula had poorer oncological prognosis, higher complication rate, and acceptable postoperative functions compared with patients without fibula invasion.

Comparative StudyLocal control of giant cell tumors of the long bone after aggressive curettage with and without bone cement.
Aggressive curettage has been well established for the treatment of giant cell tumors (GCTs) of the bone. The purpose of this study was to review our experience and evaluate the role of different implant materials in patients with GCTs of the extremities after aggressive curettage. ⋯ The use of bone cement was associated with a significantly lower recurrence rate than bone grafting following aggressive intralesional curettage to treat benign giant cell tumors of the long bone. Better MSTS functional results were also observed in the bone cement group compared to the bone graft group.

Evaluation of bone heating, drill deformation, and drill roughness after implant osteotomy: guided surgery and classic drilling procedure.
This study evaluated and compared bone heating, drill deformation, and drill roughness after several implant osteotomies in the guided surgery technique and the classic drilling procedure. ⋯ During preparation of implant osteotomies, the guided surgery technique generated a higher bone temperature and deformed drills more than the classic drilling procedure. The increase in tissue temperature was directly proportional to the number of times drills were used, but neither technique generated critical necrosis-inducing temperatures. Drill deformation was directly proportional to the number of times the drills were used. The roughness of the drills was directly proportional to the number of reuses in both groups but tended to be higher in the GG group.

The aim of this study was to compare the effects and indications of minimally invasive plate osteosynthesis (MIPO) and limited open reduction (LOR) for managing distal tibial shaft fractures. A total of 79 cases of distal tibial shaft fractures were treated surgically in our trauma center. The 79 fracture cases were classified into type A, B, and C (C1) according to the Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification, with 28, 32, and 19 cases, respectively. ⋯ LOR promoted bone healing and lowered the non-union rate of several simple-distal tibial shaft fractures. Thereafter, the incidence of soft tissue complication was not significantly increased. However, for complex and comminuted fractures, MIPO was the preferred method for correcting bone alignment and protecting soft tissue, leading to functional recovery.
