ReviewNew concepts in high tibial osteotomy for medial compartment osteoarthritis.
Medial compartment osteoarthritis remains a clinical challenge for the orthopedic surgeon. Accurate preoperative planning is an integral part of management. MCOA with genu varum is not a single condition but a family of related deformities. ⋯ In total knee replacement, the important emphasis has been on achieving correct bony alignment and soft-tissue balance. With osteotomy, the emphasis has been on bony alignment. However, soft-tissue balance should also be considered an important element in preserving the knee in osteotomy surgery.

In the period 1984-1991, 33 lower limb reconstructions were performed with an uncemented Kotz modular femur tibia reconstruction (KMFTR) prosthesis after resection of 32 malignant bone tumors and 1 benign giant cell tumors. Tumor localization was proximal femur in 12, distal femur in 17, and proximal tibia in 4. ⋯ In 2 of the 4 patients undergoing combined distal femur and proximal tibia resection, a deep infection developed, and above-knee amputation was performed. One local recurrence occurred after proximal femur resection.

Comparative Study[Surgical limb lengthening in patients of short stature. Indications, complications and results].
The authors report their experience in limb lengthening in 55 patients with short stature. ⋯ Such a treatment must be undertaken in specialized centers, not only owing to surgical difficulties, but especially because it requires a continuous clinical check and a strong post-operative physiotherapy.

Clinical TrialDouble vascularized fibulas for reconstruction of large tibial defects.
Vascularized fibular grafts have proven to have many advantages over nonvascularized transplants for treatment of large segmental bone defects in the extremities. Fibulas are typically impacted into the medullary canal and fixed with wires or screws. Consolidation has often been delayed and full weightbearing was only possible after graft hypertrophy, usually 12 to 18 months after reconstruction. ⋯ In six patients, healing was uneventful. In one patient, hypoperfusion of the lower extremity and the vascularized grafts eventually resulted in a below-knee amputation. In all six successful cases, union resulted within 3 months.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative StudyAnalysis of the external fixator pin-bone interface.
External fixator pins were inserted into tibiae of dogs under four in vivo loading conditions to examine the mechanism of pin loosening. Pins were quantitatively measured for pin torque resistance, and the pin tracts were studied radiographically and histologically. The pins holding an unstable fracture had more gross pin loosening. ⋯ Unstable external fracture fixation is another important factor in producing pin loosening. Pins loaded under unstable fracture fixation had the highest incidence of gross loosening. When applying an external fixator, the fracture rigidity should be critically evaluated and, if necessary, protected weight bearing must be introduced initially to minimize pin loosening.
