BACKGROUND: The purpose of this retrospective study was to analyze the utility of a trochanteric claw plate in the treatment of an ununited greater trochanter following total hip arthroplasty. METHODS: From 1986 through 1999, seventy-two consecutive procedures to reattach an ununited greater trochanter were performed in seventy-one patients. The average age at the time of the index arthroplasty was 66.2 years. The arthroplasty that resulted in the nonunion of the greater trochanter was primary in fifty-four hips, a first revision in sixteen hips, and a second and third revision in one hip each. The mean duration between the hip replacement and the treatment of the nonunion was 8.1 months. The greater trochanter was fixed with the trochanteric plate alone in forty-eight hips and with the plate in conjunction with vertical wires in the remaining twenty-four hips. The average duration of follow-up was 5.1 years. RESULTS: Osseous union occurred in fifty-one of the seventy-two hips. There was a persistent nonunion in twelve hips and fibrous consolidation in the remaining nine hips. The mean time to osseous consolidation was 3.7 +/- 2.1 months (range, two to twelve months). The mean Merle d'Aubigné hip score was 16.1 +/- 2.4 points at the time of the latest follow-up. A highly significant improvement in function was achieved only in the group with osseous consolidation (p < 0.0001). The highest rate of osseous union was achieved when vertical wires had been used in conjunction with the claw plate. Union occurred in twenty-one of the twenty-four hips in that group (p = 0.025). CONCLUSIONS: Nonunion of the greater trochanter following total hip arthroplasty can be successfully treated with a trochanteric claw plate. The use of adjunctive vertical wires results in better osseous contact and union. 相似文献

Revision total hip replacement has traditionally required a trochanteric osteotomy for successful cement removal and component reinsertion. In this study the authors have concluded that in most instances the revision total hip replacement procedure can be successfully performed without trochanteric osteotomy. The advantages are underscored by the high percentage of trochanteric complications with trochanteric osteotomy for revision total hip replacement and the ease of rehabilitation without trochanteric osteotomy. Also, improved functional results without trochanteric osteotomy were noted. The specific indications for the procedure included revision total hip replacement with ununited prior trochanteric osteotomy, revision total hip replacement with femoral shaft fractures, and revision total hip replacement with stem fractures requiring only acetabular revision. The contraindications to the procedure are fibrous union or ununited trochanteric osteotomy from prior total hip replacement, severe acetabular protrusion of the acetabular component, advanced myositis ossificans, ankylosis of the hip, and advanced proximal femoral osteoporosis. The operating room records, x-rays, and outpatient records of 63 total hip revisions in 52 patients were reviewed. There was a minimum 2-year follow up with a range from two years to seven years. The patients were divided into two groups, comparing 21 trochanteric osteotomized revisions to 44 with trochanteric sparing techniques. Both groups were analyzed for age, type of implant, intraoperative perforation of femur, intraoperative femoral shaft fractures, intraoperative cortical window, component malpositioning extraneous cement, intraoperative blood loss, operating time, postoperative leg length inequality, persistent abductor weakness, average first day of ambulation, wound infection, dislocation, nonunion of the trochanter, and postoperative pain. In the nonosteotomized group, there was a 21% decreased blood loss, a 14% decrease in persistent abductor weakness, a 14% decrease in subluxation and dislocation, a 30% decrease operating time and a 50% reduction in intraoperative femoral perforation. In the osteotomized group there were six cases of fibrous union of the greater trochanter, two cases requiring removal of broken wires for trochanteric bursitis. A detailed surgical technique and representative cases are presented. In carefully selected cases, revision total hip replacement is optimally performed without trochanteric osteotomy. Postoperative trochanteric problems of nonunion, broken wires, bursitis, and abductor weakness can effectively be eliminated by avoiding trochanteric osteotomy.(ABSTRACT TRUNCATED AT 400 WORDS) 相似文献

BACKGROUND: The use of an extended trochanteric osteotomy facilitates exposure and aids in the removal of a well-fixed femoral implant and cement during revision total hip arthroplasty. Occasionally, nonunion, fracture, and trochanteric migration have been reported following osteotomy. We evaluated the rate of healing of the osteotomy site and of implant stability when fixation was accomplished with use of vertical trochanteric and horizontal metaphyseal cable fixation (combined cable fixation). METHODS: The clinical and radiographic results of revision total hip arthroplasty with use of an extended trochanteric osteotomy followed by implantation of a distally porous-coated component and combined cable fixation of the osteotomy site in forty-two consecutive patients (forty-three hips) were reviewed. Intraoperative fracture at the osteotomy site occurred in five hips (12%). RESULTS: All osteotomy sites healed by six months, with an average time to union of fifteen weeks. One implant subsided 5 mm in a patient in whom a fracture had occurred at the time of the osteotomy. No trochanteric migration occurred. Two patients required a reoperation: one because of instability, and another because of recurrent infection. CONCLUSIONS: The extended trochanteric osteotomy facilitates revision of a well-fixed femoral component. Despite occasional intraoperative fracture at the osteotomy site, combined vertical trochanteric and horizontal metaphyseal cable fixation resulted in an excellent rate of healing and implant stability. 相似文献

A system for trochanteric osteotomy and reattachment for total hip arthroplasty with a ninety-nine percent union rate 总被引:2,自引:0,他引:2
In certain circumstances osteotomy of the greater trochanter in total hip arthroplasty is of benefit. To attack the problem of nonunion following trochanteric osteotomy, the authors apply several different wiring techniques. To quantify the efficacy of these approaches, they have reviewed 804 consecutive total hip arthroplasties in which the greater trochanter was osteotomized, including 725 primary total hip arthroplasties. Ninety-nine percent of the trochanters united. Among the 79 revision cases, the trochanter united in every case. The use of two independent vertical wires with one transverse wire was the preferred technique. 相似文献

Fifty-nine cases of trochanteric wire revision following hip arthroplasty with trochanteric osteotomy and reattachment were identified and their outcome was studied. Two were infected and were excluded. Five were revised for instability: four became stable while one continued to have persistent dislocation. Fifty-two were revised for pain, 36 by removal of the trochanteric wire and 16 by reattachment of the greater trochanter. Successful relief of pain was obtained in less than half the cases. There was no difference in the incidence of back pain, wiring technique, trochanteric advancement, previous surgery to the same hip, trochanteric size or the pattern of wire breakage in the successfully treated group and the unsuccessful group. Neither was the removal of intact wire from a united trochanter any more certain of relieving pain than removal of broken wire from an un-united trochanter. Six patients later required revision for loosening or infection. These results indicate the need for full radiological and haematological investigation before exploration of the greater trochanter. At exploration for pain the wires should simply be removed as we could show no successful union after late reattachment of the trochanter in the absence of instability. 相似文献

A review of the results of the extended trochanteric osteotomy through a modified direct lateral approach in revision total hip arthroplasty was done. We reviewed 44 patients (45 procedures) at a minimum of 2 years followup (mean, 3.8 years; range, 2.1-7.2 years). There were 26 men and 18 women with a mean age at the time of surgery of 70.8 years (range, 36.9-90.4 years). Indications for use of the trochanteric osteotomy included facilitation of cement removal (25 procedures), proximal femoral varus deformity (14 procedures), trochanteric malposition (five procedures), and previous trochanteric osteotomies with significant bony overgrowth (three procedures). The mean length of the osteotomy was 133.9 mm. The mean migration of the osteotomized fragment was 2.1 mm (range, 0-20 mm) with significantly more proximal migration seen with the use of cerclage wires when compared with cables. There were two cases of trochanteric escape, for which the patients required repeat open reduction internal fixation. There were two late fractures of the greater trochanter. One femoral component had early subsidence for which the patient required re-revision with a further extended trochanteric osteotomy. The mean time to union of the remaining 40 hips was 10.3 months (range, 6-24 months). There only was one dislocation postoperatively. The extended trochanteric osteotomy through the modified direct lateral approach in revision total hip arthroplasty is a reproducible and reliable technique with a lower dislocation rate but a higher incidence of trochanteric fracture and escape than previously described with its use in the posterior approach. 相似文献

BACKGROUND: The purpose of this study was to assess the rate of union, time to union, and complications associated with the extended slide trochanteric osteotomy. We also evaluated how outcomes were influenced by the preoperative cortical-bone thickness, the preoperative cancellous-bone quality of the greater trochanter, the number of cables used to reattach the trochanteric osteotomy fragment, and the use of cortical strut augmentation. METHODS: We reviewed the results for forty-six hips in forty-five patients who underwent a revision total hip arthroplasty with an extended slide trochanteric osteotomy between December 1991 and December 1996. Twenty-three patients were men, and twenty-two were women; the mean age at the time of the operation was 66.3 years. Two hips had an isolated acetabular revision, fifteen had an isolated femoral revision, and twenty-nine had acetabular and femoral revisions. One patient (one hip) was lost to follow-up. RESULTS: At a mean of forty-four months after the operation, the rate of union of the distal osteotomy site was 98 percent (forty-four of forty-five hips), with no change in the femoral component position. The time to union was not significantly correlated with the number of cables, the preoperative cortical-bone thickness, or the preoperative cancellous-bone quality of the greater trochanter. Interestingly, the time to bridging-callus union was significantly longer in the hips with a strut allograft than in the hips without a strut allograft (p = 0.04, t test for independent samples). Two fractures of the osteotomy fragment occurred, but neither necessitated another revision. CONCLUSIONS: The extended slide trochanteric osteotomy allows extensive acetabular and femoral exposure, facilitates removal of distal cement or a well fixed porous-coated stem, and allows reliable reattachment and healing of the trochanteric fragment. 相似文献

The radiographic results of 73 anterior trochanteric slide osteotomies were retrospectively reviewed at an average of 36 months after primary hip arthroplasty to determine the incidence of nonunion of the trochanter and complications related to trochanteric hardware. In each case, the trochanter was retracted anteriorly, with the gluteus medius and vastus lateralis muscle insertions left intact. Reattachment was performed with 2 monofilament wires or cables passed through the lesser trochanter in each case. Ninety-two percent of the trochanters healed; nonunion was associated with anterior displacement of the trochanteric fragment with external rotation of the femur. The incidence of repeat surgery for hardware-related problems was 28%. Although the slide osteotomy prevented proximal migration of the trochanteric fragment, the incidence of hardware complications was too high to justify the routine use of this approach in primary hip arthroplasty. 相似文献

Clinical and radiographic results of trochanteric osteotomy after revision hip arthroplasty in 62 hips were reviewed. The
osteotomized fragment had been reattached using the Dall-Miles cable grip system in each hip. The patients' average age at
operation was 64.4 years (range, 40–86 years). The average duration of follow-up was 30.0 months (range, 12–60 months). Trochanteric
nonunion was found in 19 hips (30.6%). Trochanteric nonunion developed in 14 (38.9%) of 36 hips with each cable attached around
the medial cortex bone, in 2 (16.7%) of 12 hips with each cable passed in a drill hole, and in 3 (21.4%) of 14 hips with one
cable passed through a hole and the other attached around the medial cortex. Fragmentation developed in 18 hips (29.0%). In
3 of these 18, the fragments had migrated close to the acetabular component. Cable breakage was seen in 4 hips (6.5%), and
bone absorption around the cable in the medial cortex was seen in 17 hips (27.4%). There were 16 hips (25.8%) that presented
symptoms at the greater trochanter, including spontaneous pain and tenderness. When the Dall Miles cable grip device is used
for reattachment of the greater trochanter, attention should be paid to the condition of the trochanteric bed, the tension
of the abductor muscles, and to the placement of the cables and the H-shaped grip.

Ninety-nine patients (106 hips) with a trochanteric osteotomy during revision total hip arthroplasty were evaluated at a minimum of 5 years after surgery. Trochanteric reattachment was done with monofilament cobalt-chromium wires. The influence of the following variables on trochanteric union was examined: a prior trochanteric osteotomy, an existing trochanteric nonunion, trochanteric advancement to the lateral femur, use of vertical (in addition to horizontal) wires through the trochanter, and use of a trochanteric mesh. Overall, union occurred in 92 of the 106 trochanters (87%). Fifty-three of 61 trochanters (86.9%) healed after an initial osteotomy, whereas 34 of 38 (89.5%) healed after a repeat osteotomy. Five of the 7 trochanters with an existing nonunion healed, and 5 of 5 trochanters reattached to a bulk allograft healed. Twenty-nine of 36 trochanters (80.5%) reattached to cancellous bone healed, compared with 58 of 65 (89.2%) that were reattached to the lateral femoral cortex. Ninety percent (83/92) of the trochanters reattached in conjunction with use of a chrome-cobalt mesh healed, compared with 64.3% (9/14) of those without (P < .05). Of the variables studied, only the use of mesh was statistically significant. Osteotomy through a previously healed trochanter, advancement of the trochanter to cortical bone, existing trochanteric nonunion, trochanteric reattachment to a bulk allograft, and lack of vertical wires for fixation did not adversely affect the likelihood of obtaining trochanteric union. 相似文献

Sciatic neuropathy secondary to migration of trochanteric wire following total hip arthroplasty 总被引:4,自引:1,他引:3
Delayed sciatic neuropathy secondary to migration of a free segment of trochanteric wire in an otherwise successful total hip arthroplasty seems not to have been reported previously. A 60-year-old woman with a total hip arthroplasty with a lateral transtrochanteric approach had the trochanter reattached with two 18-gauge Vitallium wires. The osteotomy healed uneventfully despite a break in the vertical wire ten days after surgery. Five years and ten months later, the patient began to have severe sciatic pain. Roentgenograms showed a free fragment of trochanteric wire posterior to the hip joint. On exploration, the 2-cm wire fragment was found to lie entirely within the epineurium of the sciatic nerve. 相似文献

OBJECTIVE: To evaluate the results of valgus intertrochanteric osteotomy for varus nonunion and malunion of trochanteric fractures. SETTING: University hospital. DESIGN: Retrospective clinical study. PATIENTS: Fifteen patients (age range 29-84 years) with varus malunion (11 cases) or varus nonunion (4 cases). Indication for surgery was nonunion or varus malunion with limb shortening greater than 2 cm associated with limp, abductor muscle insufficiency, hip pain, and back pain. INTERVENTION: The patients were treated by a valgus intertrochanteric osteotomy fixed with a 120 degrees double-angled blade plate. RESULTS: Average follow-up was 5.5 years (range 2-10 years). Fourteen patients healed without complications: 12 patients within 4 months; 2 delayed unions within 6 months. One patient required revision surgery for a loss of fixation due to a fall 6 weeks after surgery. This osteotomy also healed. Average lengthening achieved by osteotomy was 2 cm (range 1-5 cm). In all patients, the resulting range of flexion in the hip joint was greater than 90 degrees, Harris hip score before surgery was 73 points (range 61-83), and after surgery 92 points (range 76-98). Osteoarthritis or avascular necrosis of the femoral head did not develop in any of the cases. CONCLUSION: Valgus intertrochanteric osteotomy is an effective procedure that reliably restores hip function in trochanteric malunion or nonunion. 相似文献

The development of cerclage systems for fixation of greater trochanteric osteotomies has progressed from monofilament wires to multifilament cables to cable grip and cable plate systems. Cerclage wires and cables have various clinical indications, including fixation for fractures and for trochanteric osteotomy in hip arthroplasty. To achieve stable fixation and eventual union of the trochanteric osteotomy, the implant must counteract the destabilizing forces associated with pull of the peritrochanteric musculature. The material properties of cables and cable grip systems are superior to those of monofilament wires; however, potential complications with the use of cables include debris generation and third-body polyethylene wear. Nevertheless, the cable grip system provides the strongest fixation and results in lower rates of nonunion and trochanteric migration. Cable plate constructs show promise but require further clinical studies to validate their efficacy and safety. 相似文献

Extensive bone loss raises formidable challenges in total hip revision. The aim of this study was to evaluate the results of reconstruction using a cemented long-stem and massive structural allograft implanted in a filleted proximal femur, with and without the use of a trochanteric claw plate. Between 1988 and 2001, 44 revisions were performed in 42 patients. After a transtrochanteric approach, the femur was cut longitudinally. A long, cemented Charnley-type prosthesis was used, and flaps of the residual femur were folded around the allograft. The greater trochanter was reinserted with wires in all revisions, and with both wires and a claw plate in 20 revisions. Mean follow-up was 7.15 years (range: 3-16); seven patients, died and four were lost to follow-up. The follow-up exceeded five years in 34 patients. The major complication was nonunion of the greater trochanter, which occurred in 25 cases. Six dislocations, one recurrence of infection, two mechanical loosening, and two fractures below the stem were also recorded. The use of a trochanteric claw plate significantly improved final hip stability, even in patients with nonunion. Femoral reconstruction with a massive structural allograft is reliable and long-lived, and serious complications and long-term resorption are uncommon. The use of a trochanteric claw plate significantly improves final hip stability. Level of evidence: Therapeutic study, level III (retrospective comparative study). 相似文献

BACKGROUND: The extended trochanteric osteotomy has been a useful approach for patients undergoing revision total hip arthroplasty; however, it has not been well described as an approach for those undergoing complex primary total hip arthroplasty. The purpose of the present report is to describe our experience with the use of an extended trochanteric osteotomy for patients undergoing complex primary total hip arthroplasty. METHODS: Six patients underwent primary total hip arthroplasty with use of an extended trochanteric osteotomy. The reasons for the use of this technique included severe femoral deformity, removal of intraosseous hardware, and high-riding developmental hip dysplasia. A fully porous-coated femoral component with diaphyseal fixation was used for all reconstructions. The mean age of the patients at the time of surgery was fifty-six years. Clinical and radiographic evaluation was performed at a minimum of two years. RESULTS: After a mean duration of follow-up of fifty months, all patients had an osseointegrated, stable femoral component. The site of the extended trochanteric osteotomy healed in five of the six patients. One patient had nonunion at the osteotomy site and a fracture at the base of the greater trochanter, with a subsequent fracture of the femoral component. The mean Merle D'Aubigné and Postel pain and walking scores improved from 2.2 and 2.3 preoperatively to 5.3 and 4.7 at the time of the final follow-up (p < 0.001). CONCLUSIONS: The extended trochanteric osteotomy is useful for the correction of femoral deformity and facilitates the removal of intraosseous hardware in carefully selected patients undergoing complex primary total hip arthroplasty. 相似文献

The outcome of sliding trochanteric osteotomy in revision total hip arthroplasty was assessed by comparing preoperative and postoperative static radiographic biomechanics and clinical hip abductor function of 22 consecutive operations (20 patients). Preoperative and postoperative pelvic radiographs were reviewed to quantify the biomechanical reconstruction of the hip abductor mechanism. Abductor muscle length and abductor moment arm were increased significantly (P <.05) by the operation. There was a significant (P <.05) increase in maximum degrees of active hip abduction from the preoperative to the postoperative state, an average of 32 months (range, 6-65 months) after surgery. The dysfunction index (a radiographic representation of hip torque) correlated positively (r =.63; P <.05) with active hip abduction. Sliding trochanteric osteotomy improves abductor biomechanics and may protect against trochanteric migration in revision total hip arthroplasty. 相似文献
