Foot function after subtalar distraction boneblock arthrodesis
The Journal of Bone and Joint Surgery, 2004
Subtalar distraction bone-block arthrodesis for malunited calcaneal fractures was performed in 31 patients (26 men, five women), with a mean age of 38.5 years. The mean time from injury to arthrodesis was 36 months. There were no cases of nonunion. One patient had an early dislocation of the bone block requiring a repeat arthrodesis, and one had a soft-tissue infection. The mean AOFAS hindfoot score improved significantly from 23.5 before operation to 73.2 at a mean follow-up of 33 months (p > 0.001). Compared with the unaffected side, the talocalcaneal height was corrected by 61.8%, the talus-first metatarsal axis by 46.5%, the talar declination angle by 38.5% and the talocalcaneal angle by 35.4%. Dynamic pedobarography revealed a return to normal of the pressure distribution during roll-over and a more energetic gait. The distribution of local transfer of load correlated well with the AOFAS score. The amount of correction of the heel height correlated with a normal pattern of p...
Tibiotalocalcaneal arthrodesis in treatment of hindfoot pain and deformity
Foot and Ankle Surgery, 2006
Background: Tibiotalocalcaneal arthrodesis is a salvage procedure for patients with severe disease of the ankle and subtalar joints. Methods: We report a series of 26 consecutive patients (26 feet) operated on by a single surgeon in a single centre over a 4 year period with average follow up of 26 months (6-50 months). Average age of the patients was 57 years (28-72 years). Patients had combined ankle and subtalar joint arthrodesis by an intramedullary nail device. Indications for surgery were pain except for the Charcot joints. Only five patients did not have severe deformity pre-operatively. Patients were assessed by AOFAS Ankle-Hindfoot Scale, SF-12, patient satisfaction scores and radiologically. Results: Two patients have died of unrelated causes. Clinically and radiologically 15 have solid union (65%). Six patients have signs of radiological non-union/delayed union but are clinically asymptomatic. Two patients required amputation. One patient has had revision surgery for infected non-union. Most patients are very satisfied with the procedure (79%) and would undergo the procedure again (83%). Conclusion: Majority of cases with combined ankle and subtalar joint arthrosis and severe deformity can be salvaged.

Tibiotalocalcaneal arthrodesis is a salvage procedure for severe hindfoot/ankle deformities, arthritis, avascular necrosis of the talus, failed total ankle replacement, and Charcot neuroarthropathy. The methods for fixation include anterior and lateral plates, screws, retrograde intramedullary nails, and external fixation. The purpose of the present report was to describe the short-term radiographic outcomes and technique using a posterior approach with an anatomic-specific locking plate for tibiotalocalcaneal arthrodesis. Nine patients underwent tibiotalocalcaneal arthrodesis using a posterior locking plate. The medical records and radiographs were retrospectively reviewed for patient demographics, fusion rate, complications, and patient satisfaction. The mean patient age was 57.89 ± 10.8 years, and the follow-up period was 11.11 ± 4.74 months for the patients undergoing posterior tibiotalocalcaneal arthrodesis. The mean time to weightbearing in a shoe with a brace was 16.68 weeks....
Minimally invasive, no hardware subtalar arthrodesis with autogenous posterior iliac bone graft
Strategies in Trauma and Limb Reconstruction, 2010
Sixteen patients underwent minimally invasive subtalar arthrodesis through a mini-invasive approach with posterior iliac graft between 2004 and 2006. No hardware was used to transfix the arthrodesis and partial weight bearing was allowed immediately. The primary indication for surgery was the squeal of fracture os calcis in terms of subtalar joint arthritis, loss of heel height, malalignment of the hindfoot, and pain with weight bearing. There were 12 male and 4 female patients with a mean age of 30 (range 17-52). Patients were followed up for a period of 40.8 months (range 36-48 months). The mean interval from injury to fusion was 2 (?0.6) years ranging from 6 months to 6 years post fracture. The average clinical rating scale based on the American Orthopaedic Foot and Ankle Society (AOFAS) improved from 36 preoperatively to 78 at the latest follow-up (P \ 0.05). Union rate was 94%. Radiographic evaluation revealed a mean increase in calcaneal inclination of 6.25 ? 8.3°(P \ 0.07) and a mean increase in the lateral talocalcaneal angle of 7.42 ? 10.2°(P \ 0.08). Complications were graft nonunion in 1 patient and transient tendoachilles tendinitis in another. This technique can be used to decrease the morbidity associated with the late complications of os calcis fractures by aligning the hindfoot, restoring the heel height and correcting calcaneal and talar inclination. It offers the advantage of early weight bearing while avoiding hardware complications.
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 Oilier'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 os-teotomy 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 decli-nation angle, it is suitable for those patients with a "ba-nana"-shaped calcaneus malunion. If the patient has prominent anterior ankle pain caused by tibiotalar im-pingement, we believe that a distraction subtalar arthro-desis would be more appropriate.
Posterior Bone Block Distraction Arthrodesis of the Subtalar Joint: A Review of 22 Cases
The Journal of Foot and Ankle Surgery, 2008
Twenty-two patients underwent a posterior bone block distraction arthrodesis of the subtalar joint between 1999 and 2006. The indication for surgery was loss of heel height, subtalar joint arthrosis, decreased talar declination with associated tibiotalar impingement, insufficient Achilles tendon function, malalignment of the rear foot, and pain with ambulation. There were 11 male and 11 female patients with a mean age of 46.7 years (range 20 to 71). The mean follow-up period was 27.3 months (range 12 to 63.9 months). Radiographic analysis revealed a mean increase in heel height of 6.09 mm (P= .0001), 5.83 degrees (P= .12) of lateral talocalcaneal angle, 5.5 degrees (P= .06) of talar declination, and 5.23 degrees (P= .07) of calcaneal inclination. The talo-first metatarsal angle increased an average of 4.5 degrees (P= .18). There was a 95.5% union rate. Postoperative complications included nonunion in 1 patient, subsidence of graft (collapse) in 1 patient, wound dehiscence in 3 patients, painful hardware in 7 patients, sural neuritis in 1 patient, superior cluneal nerve dysfunction in 1 patient and one mild varus malunion. Posterior bone block distraction arthrodesis can be successfully used to restore heel height, realign the foot, and decrease the morbidity associated with late complications of calcaneal fractures, as well as, nonunion and/or malunion following subtalar joint arthrodesis, Charcot neuroarthropathy, and avascular necrosis of the talus. 4.

Background: End-stage ankle arthrosis causes severe pain and limited movement. In this case, tibiotalocalcaneal arthrodesis (TTCA) surgery forms the basis for surgical treatment in the appropriate patient group. TTCA with arthroscopy-assisted hindfoot nailing can be used to achieve a high union rate and low complication rate. In this study, we aimed to examine the early-and mid-term results of patients treated with this technique from various perspectives and to evaluate them by comparing them with the current literature. Methods: Data were collected from 25 patients who met the established criteria and underwent TTCA with posterior approach arthroscopic-assisted hindfoot nailing. In addition to the demographic data of the patients, their clinical and pain scores were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS). These scoring data were collected preoperative, postoperative 3rd month, postoperative 12th month, and at the final postoperative followup (18-24th months). Additionally, the union time and complication data during the follow-up period were examined. Results: When the AOFAS and VAS scores of the 25 patients were examined, a significant improvement was observed in the preoperative period and early postoperative period comparisons (p < 0.001). No significant change was observed between the comparison of the postoperative 12th month and last postoperative control clinical scores. While the union rate of the patients was observed to be 92%, the average union time was 13.1 ± 3.5 weeks. During follow-up, peri-implant fracture, deep infection, and non-union were observed in one patient each (12%). Conclusion: The early-and mid-term postoperative results of patients treated with TTCA surgery with posterior approach arthroscopic-assisted hindfoot nailing show that this technique may be an option with low complication and high union rates for the appropriate group of patients planned for ankle arthrodesis.
