1. The Küntscher method of intramedullary reaming and nail fixation was applied to thirty-five cases of non-union of the lower extremity, twenty femurs and fifteen tibias. A bone graft was generally not used. 2. Most of the patients were allowed to bear weight and to exercise the joints within a few days of the operation. Additional measures such as pre-operative surgery for infection or distraction of shortening were used in some cases. 3. The pseudarthrosis healed in all cases, even when infection was present. The nails were generally not removed until after healing had occurred. 4. It is concluded that the Küntscher method gives remarkably rapid consolidation and restoration of function even in difficult cases of non-union of shaft

The objective of this study was to validate the
efficacy of Takeuchi classification for lateral hinge fractures
(LHFs) in open wedge high tibial osteotomy (OWHTO). In all 74 osteoarthritic
knees (58 females, 16 males; mean age 62.9 years, standard deviation
7.5, 42 to 77) were treated with OWHTO using a TomoFix plate. The
knees were divided into non-fracture (59 knees) and LHF (15 knees)
groups, and the LHF group was further divided into Takeuchi types
I, II, and III (seven, two, and six knees, respectively). The outcomes
were assessed pre-operatively and one year after OWHTO. Pre-operative
characteristics (age, gender and body mass index) showed no significant
difference between the two groups. The mean Japanese Orthopaedic
Association score was significantly improved one year after operation
regardless of the presence or absence of LHF (p = 0.0015, p <
0.001, respectively). However, six of seven type I cases had no
LHF-related complications; both type II cases had delayed union;
and of six type III cases, two had delayed union with correction
loss and one had overcorrection. These results suggest that Takeuchi
type II and III LHFs are structurally unstable compared with type
I. Cite this article:

We performed a retrospective analysis of the clinical and radiological outcomes of total hip replacement using an uncemented femoral component proximally coated with hydroxyapatite. Of 136 patients, 118 who had undergone 124 primary total hip replacements were available for study. Their mean age was 66.5 years (19 to 90) and the mean follow-up was 5.6 years (4.25 to 7.25). At the final follow-up the mean Harris hip score was 92 (47.7 to 100). Periprosthetic femoral fractures, which occurred in seven patients (5.6%), were treated by osteosynthesis in six and conservatively in one. We had to revise five femoral components, one because of aseptic loosening, one because of septic loosening and three because of periprosthetic
In a randomised trial we compared the effects of two different antithrombotic regimens on the incidence of venographically established deep venous thrombosis (DVT) in 83 patients undergoing surgery for
A total of 20 pairs of fresh-frozen cadaver femurs were assigned to four alignment groups consisting of relative varus (10° and 20°) and relative valgus (10° and 20°), 75 composite femurs of two neck geometries were also used. In both the cadaver and the composite femurs, placing the component in 20° of valgus resulted in a significant increase in load to failure. Placing the component in 10° of valgus had no appreciable effect on increasing the load to failure except in the composite femurs with varus native femoral necks. Specimens in 10° of varus were significantly weaker than the neutrally-aligned specimens. The results suggest that retention of the intact proximal femoral strength occurs at an implant angulation of ≥ 142°. However, the benefit of extreme valgus alignment may be outweighed in clinical practice by the risk of superior femoral neck notching, which was avoided in this study.
