BACKGROUND: The purposes of this retrospective study were to review the results of isolated subtalar arthrodesis in adults and to identify factors influencing the union rate. The hypotheses were that (1) the overall outcome is acceptable but is not as favorable as previously reported, (2) complication rates, especially the nonunion rate, are higher than previously reported, and (3) factors contributing to a less favorable union rate can be identified. METHODS: Between January 1988 and July 1995, 184 consecutive isolated subtalar arthrodeses were performed in 174 adults (115 men and fifty-nine women) whose average age was forty-three years (range, eighteen to seventy-nine years). Eighty patients (46 percent) were smokers. The indications for the procedure included posttraumatic arthritis after a fracture of the calcaneus (109 feet), a fracture of the talus (thirteen feet), or a subtalar dislocation (thirteen feet); primary subtalar arthritis (thirteen feet); failure of a previous subtalar arthrodesis (twenty-eight feet); and residual congenital deformity (eight feet). Rigid internal fixation with one or two screws was used for all feet. Bone graft was used in 145 feet; the types of graft material included cancellous autograft (ninety-four feet), structural autograft (twenty-nine feet), cancellous allograft (seventeen feet), and structural allograft (five feet). Bone graft was not used in the remaining thirty-nine feet. RESULTS: Clinical and radiographic follow-up examinations were performed for 148 (80 percent) of the 184 feet at an average of fifty-one months (range, twenty-four to 130 months) postoperatively. The average ankle-hindfoot score according to the modified scale of the American Orthopaedic Foot and Ankle Society (maximum possible score, 94 points) improved from 24 points preoperatively to 70 points at follow-up. Thirty feet had clinical evidence of nonunion. The union rate was 84 percent (154 of 184) overall, 86 percent (134 of 156) after primary arthrodesis, and 71 percent (twenty of twenty-eight) after revision arthrodesis. The union rate was 92 percent (ninety-three of 101 feet) for nonsmokers and 73 percent (sixty-one of eighty-three feet) for smokers (p < 0.05). Intraoperative inspection revealed that 42 percent (seventy-eight) of the 184 feet had evidence of more than two millimeters of avascular bone at the subtalar joint; all thirty nonunions occurred in this group (p < 0.05). A nonunion occurred in three of the five feet that had been treated with structural allograft and in two of the six feet in which the subtalar arthrodesis had been performed adjacent to the site of a previous ankle arthrodesis. After elimination of the subgroups of feet in patients who smoked, those that had had a failure of a previous subtalar arthrodesis, those that had been treated with a structural graft, and those that had had the subtalar arthrodesis adjacent to the site of a previous ankle arthrodesis, the union rate improved to 96 percent (seventy-three of seventy-six). Complications other than nonunion included prominent hardware requiring screw removal (thirty-six of 184 feet; 20 percent), lateral impingement (fifteen of 148 feet; 10 percent), symptomatic valgus malalignment (five of 148 feet; 3 percent), symptomatic varus malalignment (four of 148 feet; 3 percent), and infection (five of 184 feet; 3 percent). CONCLUSIONS: To the best of our knowledge, the present study includes the largest reported series of isolated subtalar arthrodeses in adults. Our results suggest that the outcome following isolated subtalar arthrodesis is not as favorable as has been reported in previous studies. The rate of union was significantly diminished by smoking, the presence of more than two millimeters of avascular bone at the arthrodesis site, and the failure of a previous subtalar arthrodesis (p < 0.05 for all). Other factors that probably affect the union rate include the use of structural allograft and performance of the arthrodesis adjac 相似文献

BACKGROUND: This study tested the hypotheses that fusing the subtalar joint with a single lag screw from the posteroinferior calcaneus to the anterior talar neck is an effective technique and that factors affecting the time to fusion can be identified. METHODS: Between October, 1995, and July, 2002, the senior author (RAM) performed 101 isolated subtalar arthrodeses using a technique of single lag-screw fixation from posteroinferior to anterosuperior across the posterior facet of the subtalar joint combined with the application of an autograft taken from the floor of the sinus tarsi and anterior process. The average patient age was 52 (range 17 to 82) years. There were 52 women (53 arthrodeses) and 48 men (48 arthrodeses). Eight of 101 (8%) arthrodeses were revisions. The indications included posttraumatic arthritis (45), posterior tibial tendon dysfunction (18), failed prior ankle joint fusion (14), idiopathic disorders (12), hindfoot coalition (7), rheumatoid arthritis (3), and Charcot-Marie-Tooth disease (2). Fifteen of 101 patients (15%) smoked an average of 0.9 +/- 0.5 pack of cigarettes per day. RESULTS: Two of 101 joints did not fuse, resulting in an overall fusion rate of 98%. The average time to fusion was 12.3 +/- 3.4 weeks. The presence of a prior ankle fusion significantly prolonged the time to fusion of the subtalar joint (11.9 +/- 2.3 vs. 14.9 +/- 7.0, p = .003). Other factors, including smoking, revision surgery, patient age, and patient sex, did not affect time to fusion. The fixation screw was removed in 13 of 101 (13%) joints at an average of 8.8 +/- 0.5 months. CONCLUSIONS: Using a single 7.0-mm lag screw across the posterior facet of the subtalar joint results in fusion of the subtalar joint in 98% of patients. A prior ankle arthrodesis delays the time to fusion of the subtalar joint by 3 weeks. This is a simple and reliable technique for achieving fusion of the subtalar joint. 相似文献

BACKGROUND: Operative treatment of stage II posterior tibial tendon insufficiency (PTTI) is controversial. Many soft-tissue and bony procedures and various combinations of the two have been reported for treatment of stage II PTTI. Orthopaedists recognize the lateral column lengthening component of the procedure as a successful reconstructive technique. The use of cortical allograft for lateral column lengthening in the correction of pes planus in the pediatric patient population has been routine. In the adult population, however, tricortical iliac crest autograft has been the bone graft of choice. Harvest of this autograft can precipitate significant morbidity and cost. Therefore, we undertook this randomized controlled trial to compare graft incorporation and healing of allograft and autograft in the lateral column lengthening component of adult flatfoot reconstruction. METHODS: Lateral column lengthening was done as a component of operative correction for stage II PTTI in adult patients (older than 18 years) by two surgeons using similar procedures. The patients were randomized to either the allograft or autograft procedures. The primary endpoint was graft incorporation and healing as assessed by radiographs. RESULTS: The study included 33 randomized feet in 31 patients. We followed 18 feet in the allograft group and 15 in the autograft group to the point of union. There were 21 women and 10 men. There were no delayed unions, nonunions, or hardware failures. All patients in both groups achieved bony union by the 12-week followup evaluation. Two superficial foot infections were successfully treated with oral antibiotics. Two patients in the autograft group continued to have hip donor site pain at 3 months. CONCLUSIONS: This study suggests that union rates of allograft and autograft (iliac crest bone graft) are equal. The use of allograft in the lateral column lengthening component of operative correction of adult stage II PTTI appears to be a viable alternative to the use of iliac crest autograft and eliminates the morbidity and increased cost associated with autograft harvest. 相似文献

We present a check-up study of five arthrodeses of the ankle joint and five subtalar arthrodeses. The arthrodeses of the ankle joint were indicated because of hard pains after bimalleolar fractures and fractures of the pilon tibial. Subtalar arthrodeses were indicated in posttraumatic arthritis of the calcaneus after intraarticular fractures of the calcaneus. Resection-compression-arthrodesis following Charnley was used for the ankle joint, subtalar arthrodesis was done by the technic of using a corticocancellous bone graft from the iliac crest. With an average postoperative follow-up period of four years four from five patients in every group had a good results. In cases clear indication the early arthrodesis should be preferred. 相似文献

BACKGROUND: Subtalar bone-block distraction arthrodesis using structural autograft carries the risk of donor site morbidity. Recent reports suggest that structural allograft may be an attractive alternative to structural autograft in subtalar arthrodesis. This prospective study analyzes subtalar distraction arthrodesis using interpositional structural allograft. MATERIALS AND METHODS: Between 2000 and 2006, 22 patients (24 feet; mean age, 45.6 years) underwent subtalar arthrodesis with interpositional fresh-frozen femoral head structural allograft. Indications included subtalar arthrosis, loss of heel height, and anterior ankle impingement. Clinical outcome was assessed using the AOFAS ankle-hindfoot scoring system. Time to union was determined by previously reported clinical findings and radiographic evidence for bridging trabeculation between host bone and structural allograft. RESULTS: Mean followup was 35.8 months for 20 patients (21 feet) available for followup evaluation. Union was achieved in 19 of 21 patients (90%) at a mean of 15.5 (range, 11 to 19) weeks. Mean AOFAS hindfoot score improved from 21 to 71 points (p < 0.05). Radiographic analysis suggested significant (p < 0.05) improvement in all measurements. Complications included nonunion (2), varus malalignment (1), persistent subfibular impingement (1), sural neuralgia (1), and prominent hardware (2). Both patients with nonunions had avascular bone at the arthrodesis site and used tobacco products. CONCLUSION: This study supports recent publications that subtalar arthrodesis using interpositional structural allograft can have a favorable outcome. Our clinical and radiographic results suggest that restoration of hindfoot function and dimensions with structural allograft are comparable to results reported for the same procedure using structural autograft. LEVEL OF EVIDENCE: Level IV, prospective case series. 相似文献

We have retrospectively reviewed the results of 40 consecutive patients with nonunion of the scaphoid treated by the senior author (PG) between 1993 and 1996. These comprised two groups of patients. Group 1 comprised 20 patients treated between 1993 and 1994, with a Herbert screw and autograft, and Group 2, which also comprised 20 patients treated with the precision bone grafting technique which we describe. The precision bone grafting technique employs simple instrumentation to harvest bone percutaneously from the iliac crest and then insert it at the scaphoid nonunion site. The evaluation consisted of a clinical and radiological assessment of union and wrist function. Our review demonstrates a higher rate of union with the precision bone grafting technique than by the Herbert screw fixation with bone grafting. 相似文献

Arthroscopic subtalar arthrodesis has recently gained popularity in the treatment of primary subtalar or post-traumatic arthritis, coalition, or inflammatory diseases with subtalar arthritis. The present study reports the clinical and radiologic results of 19 patients (19 feet) who underwent posterior arthroscopic subtalar arthrodesis using 2 posterior portals. A total of 19 posterior arthroscopic subtalar arthrodeses (minimum follow-up of 24 months) performed without a bone graft and with 2 parallel screws were prospectively evaluated. The fusion rate was 94% (mean time to fusion 9.8 weeks). Modified American Orthopaedic Foot and Ankle Society ankle-hindfoot scale score (maximum 94 points) improved significantly from 43 to 80 points and the visual analog scale for pain score improved from 7.6 to 1.2. The 12-item short-form physical and mental scores at the last follow-up point were 52.5 and 56.4, respectively. One (5.3%) patient underwent open repeat fusion for nonunion, 2 (10.5%) patients required a second procedure for implant removal, and 1 (5.3%) experienced reversible neuropraxia. In conclusion, posterior arthroscopic subtalar arthrodesis is a safe technique with a good union rate and a small number of complications in patients with no or very little hindfoot deformity. 相似文献

Distraction arthrodesis of the subtalar joint is often used for the correction of neglected calcaneal fractures. Although different techniques have been advocated, there remains some debate as to the optimal type of bone graft for this purpose. This study retrospectively reviewed one surgeon's results for distraction arthrodesis of the talocalcaneal joint for 15 consecutive feet in 15 patients using 12 frozen femoral head and 3 freeze-dried iliac crest allografts. Indications for distraction arthrodesis in this series included neglected calcaneal fracture (n = 10), failed open reduction with internal fixation (n = 3), malunion after ankle fusion (n = 1), and subtalar joint arthritis with deformity (n = 1). The mean patient age was 47.5 (range 29 to 66) years, and the mean duration of follow-up was 20.6 (range 13 to 31) months. Complete union was achieved in 14 (93.33%) feet. Orthobiological agents were used in every case, including 7 (46.67%) platelet-rich plasma, 5 (33.33%) demineralized bone matrix combined with platelet-rich plasma, 2 (13.33%) platelet-rich plasma combined with an implantable electrical bone growth stimulator, and 1 (6.67%) demineralized bone matrix only. One (6.67%) patient developed a nonunion with collapse of the allogeneic graft, requiring revision with autogenous iliac crest bone graft. There were 8 (53.33%) minor complications, including 4 (26.66%) cases with inferior heel irritation, 2 (13.33%) with sural nerve paresthesia, and 2 (13.33%) with wound dehiscence. In conclusion, the use of allograft for subtalar joint distraction arthrodesis results in similar union rates as autogenous iliac crest grafting previously reported in the literature. 相似文献

PURPOSE: This study was designed to determine the complications associated with plate and screw fixation of thumb trapeziometacarpal arthrodesis and to compare these results with a previous report from our institution using K-wire fixation. METHOD: We retrospectively reviewed 26 trapeziometacarpal arthrodeses that used plate and screw fixation. The most common diagnosis was primary osteoarthritis and the average follow-up evaluation was 40 months. Nineteen patients were available for a clinical follow-up examination and radiographs. These results were compared with the previously published K-wire fixation group that consisted of 59 arthrodeses with an average follow-up period of 84 months. RESULTS: There were 2 (8%) painful nonunions. There were 6 (23%) hardware malpositions, most frequently associated with a screw in the trapeziotrapezoid joint. Seven (27%) arthrodeses had a second procedure, most commonly hardware removal. Twenty-one (81%) of the patients were satisfied and reported they would have arthrodesis again. In the K-wire fixation group 4 of 59 (7%) arthrodeses went on to nonunion and 2 of 59 required a secondary procedure; patient satisfaction was high (98%). CONCLUSIONS: K-wire and plate and screw fixation have comparable union rates. In the plate and screw fixation group, however, the satisfaction rate was lower and a second surgery was more common. We now recommend pin fixation when performing trapeziometacarpal joint arthrodesis. 相似文献

Forty extraarticular subtalar arthrodeses with internal fixation were performed in 26 patients with cerebral palsy who had a mobile, paralytic planovalgus deformity. We assessed the correction achieved and maintained by evaluating the clinical status, improvement in gait, correction of deformity, and foot stability. Union was achieved in a mean interval of 10 weeks with no instance of mechanical failure of the fixation screw. At a mean follow-up of 30 months, 38 feet (95%) were rated excellent or good and two were rated fair. The advantages of this technique of extraarticular subtalar arthrodesis warrant continued use of this procedure. 相似文献

Seven patients with spastic neuromuscular disease and severe hindfoot valgus deformity were treated by subtalar arthrodesis. Arthrodesis was performed in both feet at the same operation and fixed on one side with a self-reinforced poly-L-lactide (SR-PLLA) screw, and with a standard AO screw on the other side. The functional status state was improved, and radiographic union of the arthrodesis occurred in all feet. The radiograph showed better solid fusion in five feet treated with PLLA screws, similar fusion in both sides in one patient, and one slower fusion in the side treated initially with a PLLA screw. Totally absorbable SR-PLLA screws appear to be firm enough for fixation of subtalar extraarticular arthrodesis in children. 相似文献

Eighty six subtalar arthrodeses performed between 1985 and 1996 for complications associated with intra-articular calcaneal fractures were retrospectively evaluated. Patients were divided into three Groups: (I) 59 patients with calcaneal malunions (II) 13 patients with failed open reduction and internal fixation, and (III) eight patients undergoing open reductions and primary fusion for highly comminuted fractures. In each scenario, internal fixation was achieved with cancellous lag screws. Bone graft material consisted of either autogenous iliac crest graft, local graft obtained from the lateral wall exostectomy of the malunion, or freeze-dried cancellous allograft. Fusions in Groups II and III were performed in situ. Fusions in Group I were performed either in situ or utilizing a variety of reconstructive procedures depending upon the type of malunion encountered. Eighty three of the 86 fusion attempts were successful following the initial operations for a union rate of 96%. Fusion rates were similar regardless of the graft material used. Complications included four varus malunions, four cases of osteomyelitis, and two cases of reflex sympathetic dystrophy. A statistically significant shorter hospital stay was found for patients not undergoing iliac crest bone graft procedures. Eighty patients with at least two year follow up achieved a mean American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score of 75.0. Scores were similar for all three groups and for the various types of reconstructive procedures used. No correlation was found between postoperative talar declination angle and the AOFAS ankle-hindfoot score. Worker's compensation patients tended to have a poorer clinical outcome. 相似文献

Arthrodesis of the ankle (AA) or the subtalar joint (AST) is still a necessary treatment in case of painful posttraumatic arthrosis or paresis of the muscles after compartment syndrome. Today the alloplastic ankle joint replacement does not satisfy. Many treatments of arthrodesis with minimal or extended resection of the joint surface with or without bone transplantation are described in literature. We present in detail a new developed technique of press-fit dowel arthrodesis (KDA) for the ankle and subtalar joint. After adjustment of the joint position and retention with Kirschner wires the surface of both sides of the joint surface and underlying bone is removed by a cannulated diamond bone cutting device. Dowels from the anterior iliac crest are impacted in the cutted joint defect. The dowels are 1/10 mm bigger in dimension than the primary defect in the joint surface. The surgery will be completed with a compression screw osteosynthesis, at the ankle joint transarticular through the lateral and medial malleolus, at the subtalar joint from plantar. Ten patients have treated by press-fit-KDA (female 2, male 8; AA 7, 33.6 +/- 9 y; AST 3.38 +/- 10.9 y). The indication for KDA was in nine cases a severe posttraumatic arthrosis, in one case the paretic malfunction after compartment syndrome. The arthrodesis were clinically and radiologically consolidated after 8.2 +/- 1.9 weeks. At this time the patients showed no symptoms and were fully mobilised with complete weight-bearing. The advantages of KDA: preservation of the outline of joint and hindfoot, preservation of length of the leg and outline of iliac crest, no risk for the soft tissue, quick consolidation of the arthrodesis, no need of external fixation. The technique is also suitable for other indications as presented. 相似文献

In this study we compared the results of three methods of fixation for scaphoid non-union. The implants used were the AO 2 mm mini-fragment screw, the Herbert screw and the Kirschner (K) wires. Between 1990 and 1999, 132 patients underwent surgery for scaphoid fractures. We used the modified Filan and Herbert classification. Patients with acute fractures and patients requiring vascularised bone grafts were excluded. Twenty-six non-unions were fixed with an AO mini-fragment screw, 58 with a Herbert screw, and nine with K-wires. Radiological union was achieved in 85% of cases using the AO screw, 77% using the Herbert screw and 55% using the K-wire fixation. Statistically there was no significant difference between the AO and Herbert screw groups in terms of rate and speed of radiological union. The mechanical strength of the implant and the compression achieved did not seem to influence the union rate and speed. The type of bone graft (iliac crest or distal radius) did not significantly affect the union rates. Finally, K-wire fixation, either as a primary method or as a salvage procedure, produced inferior results and required prolonged immobilisation in plaster. 相似文献

BACKGROUND: Subtalar arthrodesis is a reliable procedure for pain relief and improved function in patients with isolated subtalar arthritis. Arthroscopic subtalar arthrodesis (ASTA) was designed to improve upon traditional methods by using a minimally invasive technique. However, posterior arthroscopic subtalar arthrodesis (PASTA) has not been described. The purpose of the present study was to investigate the early results of PASTA. METHODS: A retrospective review of 11 feet in 10 patients (one bilateral) that had PASTA was conducted. Inclusion criteria were isolated subtalar arthritis with no or minimal deformity and no significant bone loss. Exclusion criteria included patients requiring adjunctive open procedures or who had significant deformity. The technique involved prone positioning, two posterolateral portals and one posteromedial portal, posterior talocalcaneal facet debridement, percutaneous cancellous allografting and internal screw fixation. Outcome measures included patient satisfaction, the modified American Orthopaedic Foot and Ankle Society (AOFAS) score, union rate, time to union, and postoperative complications. RESULTS: All patients were discharged the day of surgery or stayed one night in the hospital. Eight patients were very satisfied, one satisfied, and one patient not satisfied with the results of their surgery. The average modified AOFAS score (maximum 94 points) improved from 36 points preoperatively to 86 points postoperatively. Ten joints fused by 10 weeks postoperatively, and one patient developed a nonunion. No other postoperative complications occurred. CONCLUSIONS: For surgeons familiar with posterior ankle or subtalar arthroscopy, PASTA offers superior exposure of the posterior talocalcaneal facet, high patient satisfaction, an excellent fusion rate, and less postoperative morbidity for patients with subtalar arthritis. 相似文献

We reviewed 116 patients who underwent 118 arthroscopic ankle arthrodeses. The mean age at operation was 57 years, 2 months (20 to 86 years). The indication for operation was post-traumatic osteoarthritis in 67, primary osteoarthritis in 36, inflammatory arthropathy in 13 and avascular necrosis in two. The mean follow-up was 65 months (18 to 144). Nine patients (10 ankles) died before final review and three were lost to follow-up, leaving 104 patients (105 ankles) who were assessed by a standard telephone interview. The preoperative talocrural deformity was between 22 degrees valgus and 28 degrees varus, 94 cases were within 10 degrees varus/valgus. The mean time to union was 12 weeks (6 to 20). Nonunion occurred in nine cases (7.6%). Other complications included 22 cases requiring removal of a screw for prominence, three superficial infections, two deep vein thromboses/pulmonary emboli, one revision of fixation, one stress fracture and one deep infection. Six patients had a subtalar fusion at a mean of 48 months after ankle fusion. There were 48 patients with excellent, 35 with good, 10 with fair and 11 with poor clinical results. 相似文献

Primary subtalar arthritis is not common. In most cases, it is the late sequela of intra-articular calcaneal fracture. Subtalar arthrodesis is mostly used for the treatment of traumatic subtalar arthritis in our clinics. We have compared our early cases of in-situ subtalar fusion with our recent cases of fusion with sliding corrective osteotomy in this clinical report. From 1989 to 1992, 15 feet of 13 patients were treated with subtalar arthrodeses for subtalar arthritis caused by malunion of calcaneal fractures. Fusion in situ was done by Ollier's approach, and resection of bony protrusion was done if there was lateral entrapment syndrome. From 1992 to 1995, 13 feet of 12 patients also received subtalar arthrodeses to salvage their calcaneal fractures, but the subtalar fusion was done by wide lateral approach, calcaneal sliding corrective osteotomy, and sometimes (11 of 13 feet) with Achilles tendon lengthening to restore the calcaneal height and width. Patients of both groups experienced obvious clinical improvement in subtalar pain relief, but there was no difference with walking distance, running, or jumping. The group undergoing fusion with sliding corrective osteotomy was more satisfied with regard to cosmetic results and shoe wear. The overall satisfactory rate in the group who underwent fusion with sliding corrective osteotomy (92%) was superior to the group who underwent fusion in situ (77%). Though our method of sliding corrective osteotomy does not provide much improvement to the talus declination angle, it is suitable for those patients with a "banana"-shaped calcaneus malunion. If the patient has prominent anterior ankle pain caused by tibiotalar impingement, we believe that a distraction subtalar arthrodesis would be more appropriate. 相似文献

Between 1994 and 1999 we treated 47 patients with 48 operations for arthrodesis of the ankle joint and/or the subtalar joint. Long-term follow-up with both clinical and radiological examination was achieved in 41 patients (41 arthrodeses); this extended over a median of 29 months (range 6–62 months) after the operation. The main indication for an arthrodesis in our patients was symptomatic posttraumatic arthrosis. Compression arthrodesis with screw fixation was the surgical technique performed in the vast majority of cases.
