For patients with an extremely narrow acetabulum and slender femur, a technique for enlarging the hypoplastic structure with subsequent use of normal-sized components is advantageous. The method mentioned in this chapter is not suitable for all patients with a high dislocation of the hip joint, but it is indicated when preoperative CT scanning indi- cates the need for enlargement of the acetabulum and of the medullary canal. Selective enlargement of only the acetabulum or femoral side can be performed in selected instances.

Kanehara, Tokyo, pp 257–266 A Biomechanical and Clinical Review: The Dall–Miles Cable System Desmond M. The Dall–Miles Cable System (Stryker Orthopaedics, Mahwah, NJ, USA) has been in clinical use since 1983. It was initially developed for reattachment of the greater trochanter in low-friction arthroplasty of the hip. It is now used largely as a cerclage system, par- ticularly in revision total hip arthroplasty (THA). A biomechanical review includes a comparison of the mechanical strength of different cerclage systems. The relationship between tensile strength and fatigue per- formance is analyzed, and comparative data are presented. A review of the clinical use of cable cerclage is presented, including ﬁxation of the greater trochanter in various trochanteric osteotomy approaches to the hip, the use of the system in revi- sion THA, femoral allografts, its use in ﬁxation of periprosthetic fractures of the femur in THA, and the use of the system in augmentation of other forms of fracture ﬁxation, emphasizing its value in the treatment of fractures in soft bone. Dall–Miles, Cable, Biomechanical, Clinical Introduction Cerclage systems have been used in many clinical situations, mainly to provide, or assist in, ﬁxation of bony fragments and occasionally of long bones.
The B-osteoproﬁlers were designed to cut the proximal Bicontact stem shape into the femoral bone discount zenegra 100 mg on-line. Final bone preparation with the B-osteoproﬁlers ensures the proximal load transfer of the Bicontact hip stem buy generic zenegra 100mg online. Proximal bone contact was additionally supported by the principles of proximal load transfer; this could be conﬁrmed by analysis of the proximal bone–implant interfaces in the Gruen zones 1 and 7 purchase 100mg zenegra otc. The titanium microporous stem coating supports the peri- prosthetic bone apposition in the proximal load transfer area buy 100 mg zenegra with visa. The ﬁrst 500 Bicontact implantations in Tübingen were followed up in two prospec- tive follow-up series, cemented and cementless. Early follow-up series conﬁrmed the very low incidence of postoperative thigh pain in the cementless Bicontact implantations with comparable results to the cemented stems of similar, uncoated design. The cementless Bicontact stem series in particular formed the subject of continuous follow-up work [30–32]. The latest follow-up of this series with 250 implantations was recently published by Eingartner et al. Special aspects of the proximal load transfer could be found in cases where screw-type sockets implanted in the ﬁrst Bicontact series of 1987–1989 had loosened. Even where there was severe polyethylene wear and acetabular osteolysis, the proxi- mally coated Bicontact stem was somehow sealed against polyethylene wear particles. This remarkable feature of the titanium plasmaspray coating is the subject of further investigations. Primary and secondary Bicontact implant stability was analysed by Eingartner et al. Periprosthetic bone remodeling in the proximal coated Bicontact stem area was investigated by dual-energy X-ray absorptiometry (DEXA). The relative values of the proximal bone mineral density declined by 20% at 6 months but did not change in the subsequent follow-up periods. Bicontact was introduced into Japan in 1994 and into Korea in 1996 with speciﬁc hip stem types designed for the special requirements of the smaller femoral canal dimensions. For this reason, the Bicontact standard stem range was extended with an SD series for dysplastic femoral canal conditions and the Bicontact N series for narrow femoral canal conditions in secondary osteoarthritis. Conclusion European hip stem design concepts have inﬂuenced the successful development of total hip arthroplasty in the cemented and cementless techniques. Straight tapered hip stems offer reliable biomechanical concepts for cementless ﬁxation. Even if Current Trends in THA in Europe and Experiences with Bicontact 209 different biomechanical concepts can lead to successful implant designs, we use the favourable characteristics of the proximal bone preservation hip implant concept in our institution. Not all current trends in hip arthroplasty are based on experience and sufﬁcient clinical data. Implantation for hip arthroplasties in younger patients should not lead us to an uncritical use of less-experienced methods and implants. However, innova- tion in medicine must also be studied with new technologies that seem to be promis- ing for the beneﬁt of our patients.

It has been shown to work well in patellar tendon graft ACL reconstructions generic zenegra 100mg with visa. The adaptation of this interference screw technique to this graft has several advantages zenegra 100mg without a prescription, including its straightforward technique generic zenegra 100mg without prescription, the avoidance of graft cutting (previously seen with metal screws) buy zenegra 100mg, and ultimate resorption of the graft. An addi- tional advantage is that these screws are cannulated, allowing accurate placement of the screws into the appropriate tunnels. These results demonstrate excellent clinical results in terms of patient satisfaction and outcome. The results indicated that 33 patients (67%) had 0mm to 2mm of laxity; 13 patients (27%) had 3mm to 5mm of laxity, and 2 patients (4. One of the two patients with greater than 5mm of laxity was satisﬁed with the stability of the knee and reported an IKDC of 93; the other represented a clinical and mechanical failure of the graft. These results are consistent with other series, which have reported on soft tissue ﬁxation of hamstring grafts with the Endo-button Acufex (Smith-Nephew Richards, Warsaw, IN). The results of this technique in revision ACL surgery were sub- optimal, with increased mechanical laxity existing in each case. While this may result from either the effects on the multiply operated limb or increased laxity of associated structures, efforts should focus on improvements in these results. Intraoperative attention should focus on ensuring that when screw ﬁxation is used, the revision tunnels do not communicate with existing tunnels forming an oval tunnel with insufﬁ- cient strength to support the screw-tendon ﬁxation. An internal evaluation of the cohort of patients treated at the same sports medicine facility revealed that there was an increased prevalence of patients with between 3mm and 5mm of laxity on maximum manual KT-2000 measurements at two years (7. Although this degree of laxity is consistent with other pub- lished series using soft tissue ﬁxation of hamstring grafts, our group wished to closely evaluate these results. A three-month review of patients treated with BioScrew presented at the AANA in 1999 suggested an increased laxity in female patients. These results were not supported by a review of the ﬁrst 49 patients of this cohort to undergo a two-year follow-up (ﬁgure age and gender, Discussion 187 etc. Similarly, no correlation between gender, age, preoperative laxity, the presence of meniscal pathology, and the use of secondary tibial ﬁxation in the form of a polypropylene button was identiﬁed. Other studies have also been unable to show a gender bias to poorer outcome. Statistical tests were composed of ANOVA and ANCOVA analyses of variance to determine the effects of these factors on the side-to-side difference manual-maximum KT-2000 scores and the IKDC scores, which were used as outcome measures at two-year follow-up. Addi- tional tests with Spearman’s rank correlation were used to identify the correlations between the size of the graft (bone tunnels drilled) and the size differential between the drilled tunnel and the screw size and measurements of tunnel dilation. An evaluation of the radiographic morphology of the tunnels was performed. While osteolytic areas up to 1cm in diameter have been accompanied by pure polyglycolide (PGA) screws between 6 and 12 weeks after implantation, these ﬁndings have been very rare with a pure poly-L-lactic acid screw such as the BioScrew. This polymer has a six- month half-life and degrades by hydrolysis, as shown by Barber. In other studies the use of this screw has not been associated with osteolysis. Of 36 radiographs reviewed, it was not uncommon to see evidence of resorption of the screw adjacent to the femoral tunnel at the screw- femur interface. In ten cases the tunnels were expansive, having a diam- eter measurement on at least one radiograph, of greater than 15mm. In six of these cases, both the tibial and femoral tunnels measured greater than 15mm on at least one view. In only four of these ten cases was this expansive tunnel with a radiographic diameter of 15mm on at least one radiograph associated with a KT-2000 side-to-side value of greater than 3mm. While this appearance of the poly-L-lactic acid screws has not previously been reported, it did not affect the outcome measures. The presence of tunnel expansion could represent graft motion or an osseous response to screw resorption. At the time of these procedures, attention was not attuned to aperture ﬁxation to prevent graft motion at the graft-joint interface.
