Free flaps in the reconstruction of hand and distal forearm injuries.

We report a series of 32 free flap reconstructions following acute hand and forearm trauma. The series consists of two dorsalis pedis flaps, four scapular flaps and 26 lateral arm flaps. One flap became infected and failed completely, and a partial necrosis occurred in another flap. The transfers covered large skin defects, exposed tendons, tendon grafts, bone, bone grafts, joints, nerves and nerve grafts. The donor site morbidity was negligible. Our study shows that free microvascular flaps are a safe and convenient alternative to conventional flaps in hand surgery. The lateral arm flap seems very suitable for small and medium size defects.

Transfer of the second toe for reconstruction of the hand after trauma.

Twenty-six transfers of second toe to hand have been carried out in 25 cases. On 25 occasions the toe was anastomosed to the stump of the thumb, and in one to a metacarpal hand. Revascularization failed in five cases, but the remaining 21 healed with bony union occurring within six weeks in all cases. The mean follow up period was 52 months, range 14-81, and the results in 19 thumb cases were classified as excellent and in one as good by the Tamai score. We conclude that the microsurgical technique of transferring the second toe to the hand is challenging, but if revascularization is successful the functional results are good. Morbidity at the donor site is minimal.

Free tissue transfer for type III tibial fractures. Microsurgery in 19 cases.

We report 19 tibial fractures Types III B and C treated by free flaps. The fracture healed in 16 cases after 12 (3-54) months. In 3 cases a secondary amputation was carried out. Tibial malalignment or substantial shortening ensued in 1 case each. We conclude that coverage with free flaps, radical removal of dead bone, stable external fixation and transfer of vascularized bone may salvage the majority of Type III B and C tibial fracture with function superior to that after amputation.

[Surgery of the hand].

Hand surgery has developed into a specialist field. In Norway, hand surgery is still performed by surgeons without specialist training, with an unacceptably high incidence of poor outcome as a result. The article consists in a review of the commonest hand injuries and their treatment.

Mechanical effects of intramedullary acrylic cement on osteotomy healing in rats.

The medullary cavities of both femora in 35 rats were reamed, and bone cement was injected on the left side. A partial transverse osteotomy of the midshaft of both femora was then performed. At 0, 15, 30, 60, and 90 days following operation, the bending moment and elastic stiffness of the osteotomies were evaluated. No significant differences were found between the right and left femora. It is concluded that acrylic bone cement injected into the medullary cavity does not significantly impair the healing of osteotomies in rats.

Total hip replacement with Müller prosthesis and ICLH double cup. 2- to 6-year results of a prospective comparative study.

A prospective comparative study was made of patients in the age-group 60-79 years with osteoarthritis of the hip treated with the Müller total hip prosthesis (n = 155) and the ICLH double-cup prosthesis (n = 149). The patients were comparable with regard to sex, mean age, and body weight, and the preoperative radiographic appearance of the hips was th same in the two groups. The mean operating time was significantly shorter in the Müller group, whereas the operative blood loss and the operative complications were statistically equal. No deep infections occurred in either group. The incidence of systemic complications was low and no difference between the two groups was seen. The patients are followed up for an average of 48.5 months (range: 27-75 months). Dramatic improvement in hip function was seen postoperatively in both prosthetic groups. The Müller group had more favorable ratings than the ICLH group for pain, walking ability, hip motion, and total hip score at all follow-ups, from 3 weeks to 5 years after the operation. However, the differences were rather small and did not reach a significant level at any registration. The acetabular radiolucent zones and heterotopic bone formation were statistically equal in the two groups. No revision operations have been done in the Müller group. Two Müller prostheses have shown radiographic signs of mechanical loosening. Thirteen ICLH prostheses (8.7%)--all in female patients--have been reoperated (P less than 0.001), 12 owing to mechanical loosening and one because of pain and stiffness.(ABSTRACT TRUNCATED AT 250 WORDS)

Mechanical effects of intramedullary reaming on osteotomy healing in rats.

The effect of intramedullary reaming on the healing of stable femoral osteotomies was studied. In one group of rats reaming of the medullary cavity was performed, and a partial, transverse osteotomy was made at the mid-shaft. In the control group only the osteotomy was made. At 0, 15, 30, 60, and 90 days following operation the bending moment and the bending rigidity of the osteotomies were evaluated. There were no significant differences in these biomechanical parameters between the two groups during the experimental period. The results indicate that reaming of the medullary cavity of diaphyseal bone does not significantly impair the healing of fractures that are rigidly fixated.

Healing of stable and unstable osteotomies in rats.

In two groups of rats a partial, transverse osteotomy at the mid-shaft of the femur was made. The osteotomy was manually broken in one of the groups after the operation. The healing process of the osteotomies was evaluated at 15, 30, 60, and 90 days following operation. The unstable osteotomies healed by the formation of external callus, in contrast to the stable osteotomies, which healed by so-called primary bone union. At 90 days the bending moment and rigidity of the instable osteotomies were regained as compared to the intact right femurs. The stable osteotomies were only 67% as strong as the intact bones (P less than 0.01). The bending rigidity of the stable osteotomies was equal to that of the intact bones during the experimental period. It is concluded that instability at the fracture site is conducive to fast healing.
