“…Towards the end of the first year after injury, there was slow restoration of the mineral content but no return to the initial values in most instances. Although the average maximum loss was approximately 45%, only 25% of the initial bone mineral was missing after one year (Andersson and Nilsson, 1979).…”

Freeze-dried cortical bone can be used as a biological plate, either alone or in combination with other internal fixation devices, to stabilize fractures. In addition to it conferring mechanical stability, freeze-dried cortical bone may enhance fracture-healing and increase the bone stock. This study examined the effect of a freeze-dried allograft cortical bone plate (FACBP) on the biomechanical properties of an implant site in a canine bone defect model. Twelve adult mongrel dogs (around 4.8 kg) were used. A segmental critical-size defect (5 mm in length) at ulna diaphysis was created using an oscillating saw. The experimental animals were divided into two groups: eight dogs treated with an absorbable bone plate (FACBP) fixed by metal bone screws (Group A) and four dogs treated with a commercial stainless steel bone plate and metal bone screws (Group B). Bone healing was assessed by radiography, Dual-energy x-ray absorptiometry and a three-point bending test. The FACBP incorporated in the host bone produced complete remodeling of the cortical bone. There was no significant difference in the bone mineral density and biomechanical tests between the FACBP application site and normal ulna or a stainless steel bone plate of the ulna. These results suggest that FACBP facilitates recovery from a bone fracture by assisting in the induction of new bone formation in a defected fracture.

“…It is also known that an increase in the rate of mineral turnover is one of the early responses of bone to trauma as several investigators have reported substantial reductions in bone mass after fracture of long bones, not only at the site of the fracture but also at adjacent sites proximal and distal to it. 2 Detecting bone turnover in the hip may be an early indicator of future changes to come at the knee following ACL reconstruction.…”

Study Design: Prospective descriptive study. Objective: To determine the extent of bone mineral density (BMD) interlimb differences at several hip locations in the involved versus noninvolved lower extremity following anterior cruciate ligament (ACL) surgery. Background: Disuse following ACL reconstruction can be extensive. This disuse not only affects the soft tissue, but may also affect the skeletal structure. The extent of this disuse specific to the proximal femur has not been previously determined. Methods and Measures: BMD was assessed in 15 subjects, 17 to 51 years old, who were between 6 and 32 months post-ACL reconstruction surgery. Bone mineral content (BMC) and BMD of the femoral neck, trochanteric region, intertrochanteric region, and entire hip were measured as a primary emphasis of this study. BMD and BMC of the entire lower extremities were also measured bilaterally. Results: BMD was significantly less in the involved lower extremity compared to noninvolved lower extremity at several hip sites: 6.6% less (PϽ.001) for the trochanteric region, 4.0% less (PϽ.001) for the entire hip, and 3.4% less (P = .004) for the intertrochanteric region. No significant differences were noted comparing the entire lower extremities for either BMD (0.9%, P = .48) or BMC (3.7%, P = .09). Conclusion: BMD differences at the hip are significant in patient's postoperative ACL reconstruction, especially in the trochanteric region.

“…Extremity fracture is associated with persisting local osteopenia of considerable magnitude (Nilsson 1966, Westlin 1974, Anderson & Nilsson 1979a, not only close to the fracture, but also in adjacent bone(s). This phenomenon may perhaps contribute to subsequent fracture.…”
