Resection of calcaneonavicular coalition: Arthroscopic or open approach?

Purpose:Calcaneonavicular coalition accounts for more than half of all tarsal coalitions. Resection of calcaneonavicular coalition by an open approach is the standard treatment. Treatment of calcaneonavicular coalition by an arthroscopic approach appears promising. The objective of our study was to compare the clinical outcomes of calcaneonavicular coalition resection by open approach versus arthroscopic approach.Methods:A retrospective cohort study was conducted to evaluate 127 patients who underwent a resection of calcaneonavicular coalition from 2009 to 2017. Patients were divided into two groups according to whether an arthroscopic approach or an open approach was used. Demographics, operative parameters, and clinical outcomes (foot and ankle ability measure score, subjective score, and global ankle estimation) were assessed.Results:Arthroscopic approach was used for 81 patients and open approach for 46 patients. Treatment with arthroscopic approach resulted in a shorter hospital stay (2.6 ± 0.6 days vs 3.0 ± 0.7; p = 0.02) and a longer operative time (24.5 ± 8.1 min vs 20.5 ± 4.2; p < 0.01) than with open approach. The foot and ankle ability measure sports subscale scored significantly higher in the arthroscopic approach group (90.9 vs 77.3; p = 0.003). Revision rate was significantly higher in the arthroscopic approach group (12 (15%)) versus the open approach group (1 (2%)) (p = 0.024). Persistent symptoms (n = 12) were the main reason for revision.Conclusions:Arthroscopic treatment of calcaneonavicular coalition is associated with a higher revision rate than the open approach.Level of evidence:Level III—retrospective comparative study.

Calcaneonavicular coalition resection

Tarsal coalition is an abnormal connection between tarsal bones, caused by an embryogenic failure. Its most common forms are calcaneonavicular and talocalcaneal coalition, which are present in 53% and 37% of the cases, respectively. The onset of symptoms is related to tarsal bone ossification, and mean age for this event is estimated at 16 years for calcaneonavicular coalition. Surgical treatment is indicated for patients who did not improve symptoms with conservative treatment. The aim of this study is to present a surgical technique as a treatment option for resection of calcaneonavicular coalition associated with abnormal cuboid-navicular joint.

Long-term Outcomes of Coalition Resection in Adult Tarsal Coalition

Category:Hindfoot; OtherIntroduction/Purpose:Although the diagnosis, treatment, and natural history of tarsal coalitions has been well described in the adolescent population, there remains a paucity of orthopaedic literature on outcomes associated with coalition resection with or without interposition in the adult population. This study is the first to evaluate clinical and radiographic outcomes in adult patients with tarsal coalition resection without interposition.Methods:All patients with symptomatic tarsal coalition (subtalar, calcaneonavicular, or talonavicular) who failed conservative management and underwent coalition resection with concomitant procedures as indicated by their pathology between January 2006 and December 2014 were included in our retrospective case series. Demographics, clinical outcomes, patient comorbidity information, visual analogue scale (VAS) pain scores were collected. Advanced imaging (CT or MRI) was reviewed to determine fibrocartilaginous or osseous coalition. The primary outcome was reoperation. Secondary outcomes were change in visual analog score (VAS), and minor complications (local wound care, use of antibiotics, and skin dehiscence).Results:68 patients (52.9% males, 47.1% females; average age 35.9 years old, range 18 to 70) met inclusion. Calcaneonavicular, subtalar, and talonavicular coalitions were resected in 45.6% (n=31), 54.4% (n=37), and 0% of patients, respectively. At average final clinical follow up of 36 months, there were a total of 33 reoperations in 33.8% of patients (n=23) most commonly including subsequent fusion (n=11), exostectomy (n=10), and removal of hardware (n=15). There was no significant difference in reoperation (42.3% versus 63.1%, p=0.454) or fusion (19.4% versus 19.2%, p=0.99) following subtalar or calcaneonavicular coalition resection. Average VAS score preoperatively and postoperatively was 5.8 to 3.0. Minor complications were present in 16.2% of patients (n=11; 3 local wound care, 10 use of antibiotics, and 0 skin dehiscence).Conclusion:The present study demonstrates overall improvement in VAS score by an average of 2.8 points following subtalar and calcaneonavicular coalition resection. Although 33.8% of patients may anticipate additional surgery, the majority of patients may expect long-term maintenance of improvement in pain without subsequent fusion.

Fat Graft and Bone Wax Interposition Provides Better Functional Outcomes and Lower Reossification Rates Than Extensor Digitorum Brevis After Calcaneonavicular Coalition Resection.

Calcaneonavicular coalitions are the most common form of tarsal coalitions. The prefered treatment for symptomatic coalitions is surgical resection; however, there are no published studies that directly compare different interposition techniques. The purpose of the present study was to retrospectively compare pain relief, functional outcomes, and complications of children and adolescents who had a resection of a symptomatic calcaneonavicular coalition with interposition of fat graft, bone wax, or extensor digitorum brevis (EDB). In total, 48 patients (56 ft) underwent calcaneonavicular coalition resection-interposition at 3 institutions from July 2008 to July 2015. There were 23 feet in group 1 (fat graft), 18 feet in group 2 (bone wax), and 15 feet in group 3 (EDB). Patient demographic characteristics were similar between all groups for age, sex, coalition type, and symptoms onset. Data concerning clinical and radiographic features, surgical technique, and postoperative complications were obtained from all available medical records. Radiographs were evaluated at last follow-up to determine coalition regrowth. Preoperative and postoperative pain was assessed with the visual analog scale, and function was assessed with use of the American-Orthopaedic-Foot and Ankle Society (AOFAS) score. Pain improved to an average of 0.5 in the first group (range, 0 to 6), 0 in group 2, and 1.7 in group 3 (range, 0 to 5) (P=0.033). The average AOFAS score improved from 59 (range, 33 to 71 points) to 98 points (range, 62 to 100 points) in the fat graft group, from 50 (range, 34 to 62 points) to 98 points (range, 88 to 100 points) in the bone wax group, and from 48 (range, 30 to 60 points) to 75 points (range, 70 to 95 points) in the EDB group (P<0.001). Eight feet had regrowth of the coalition on the postoperative radiographs: 1 in group 1 (4%), 1 in group 2 (6%), and 6 in group 3 (40%) (P=0.004). Five feet from the third group developed progressive symptoms. In our study, autogenous fat graft and bone wax interposition techniques provided better pain relief, gave better functional scores, and avoided more effectively coalition reossification than EDB technique. Further studies are required to evaluate safety of bone wax as an interposition material. Level III-therapeutic.

Calcaneonavicular Coalition Resection With Pes Planovalgus Reconstruction

Calcaneonavicular coalitions can lead to a painful, rigid pes planovalgus deformity. Historical treatment of coalitions recommends resection. A newer concept in coalition treatment includes concomitant flatfoot reconstruction. In the present study, we hoped to demonstrate the ability to reconstruct a flatfoot deformity with concomitant calcaneonavicular coalition resection. We performed a retrospective comparative study of patients undergoing isolated calcaneonavicular bar excision (group A) with those undergoing calcaneonavicular bar excision and concomitant pes planovalgus reconstruction (group B). The radiographic parameters of pes planovalgus correction were measured on the pre- and postoperative radiographs, including talar head uncoverage, calcaneal inclination, and anteroposterior and lateral talo-first metatarsal angle. Calcaneonavicular coalition resection was performed using a standard technique with or without biologic spacers. Associated flatfoot reconstruction included posterior muscle group lengthening, calcaneal osteotomy, and/or midfoot osteotomy. Of the 27 patients, 20 were included in group A and 7 in group B. Their mean age was 18.1 years. Improvement was seen in the radiographic parameters for patients undergoing calcaneonavicular bar excision with concomitant flatfoot procedures, with statistical significance found in the calcaneal inclination (p = .013). Talar head uncoverage improved in both groups (p = .011). No change was found in the radiographic angles in patients undergoing isolated calcaneonavicular bar excision. No patients in either group developed recurrence of the coalition. The results of the present study demonstrated radiographic improvement in patients undergoing calcaneonavicular bar excision with concomitant pes planovalgus reconstruction. Hindfoot reconstruction with joint sparing osteotomies during coalition excision is a reasonable option to improve alignment and avoid arthrodesis.

Resection interposition arthroplasty of calcaneonavicular coalition using a lateral supramalleolar adipofascial flap

Space after the resection of calcaneonavicular coalition has been interposed by fat graft or the extensor digitorum brevis muscle. Nonvascularity of fat graft and insufficient volume of the extensor digitorum brevis muscle cause regrowth of the coalition. A pedicled lateral supramalleolar adipofascial flap was interposed into the space created by resection of the calcaneonavicular bar in the case of a 10-year-old boy. Regrowth of the coalition was successfully prevented by sufficient volume of the vascularized fatty tissue. The range of motion of the affected right ankle joint was similar to that of the unaffected side at 32 months postoperatively.

Percutaneous resection of calcaneo-navicular coalition with interposition of synthetic graft

Background Surgical resection of calcaneo-navicular coalition (CNC) with interposition of fat or muscle graft is indicated when there is failure of conservative treatment. Objectives to evaluate the clinical and functional of outcome of a new mini-invasive technique for resection of CNC and interposition of synthetic graft. Methods This is a prospective case series study on 9 patients (12 feet) with symptomatic CNC. Percutaneous resection of the CNC was done using a motorized bone burr through a small incision in the sinus tarsi under image intensifier control. After complete resection a synthetic graft of Teflon or Dacron measuring 15 mm × 30 mm was interposed to prevent re-union of the bone bar. Results The mean follow up period was 26.44 months (±1.5 SD). There was statistically significant improvement in the mean total AOFAS score from 47.89 (±8.49 SD) preoperatively to 90.22 (± 5.26 SD) at two years follow up ( P < 0.05). The mean time to return to full daily activity was 7.44 weeks (±0.88 SD) Conclusion Percutaneous resection of calcaneo-navicular bar with interposition of synthetic graft is an effective mini-invasive method for treatment of calcaneo-navicular coalition with good results in 44.4% of patients and excellent results in 55.6% of patients.

Experimental model in cadavera of arthroscopic resection of calcaneonavicular coalition and its first in-vivo application: preliminary communication

Open surgical resection of calcaneonavicular coalition is indicated after the failure of conservative treatment. Our objectives are to develop the arthroscopic surgical technique and to check the feasibility of the arthroscopic resection of the calcaneonavicular coalition. We designed and performed endoscopic resection of the calcaneonavicular ligament and part of the anterior process of calcaneus as a simulation of the coalition resection on four cadaver specimens. After this procedure, we successfully performed the first resection in a 12-year-old girl, without any soft tissue interposition. American Orthopaedic Foot and Ankle Society Hindfoot Scale was 55 before surgery, 98 after 10 weeks, and 100 after 2 years without recurrence.

Calcaneonavicular Coalition

Symptomatic calcaneonavicular coalitions treated with resection and interposition of the extensor digitorum brevis (EDB) muscle often have unpredictable improvement of symptoms. Concerns with regard to skin cosmesis from a bony prominence on the lateral aspect of the foot and inadequate filling of the resection gap potentially causing reossification have motivated us to use fat graft interposition instead. The purpose of this study was to describe our surgical technique and report our clinical and radiographic outcomes for fat graft interposition after resection of a calcaneonavicular coalition. A retrospective review of all pediatric patients surgically treated with a calcaneonavicular coalition resection from January 1999 to December 2006, was performed. Presenting symptoms and examination findings were recorded. Postoperative examinations and imaging studies were evaluated to grade reossification, and functional outcomes were assessed for all patients with minimum 1-year postoperative follow-up. In addition, a cadaveric study was performed to compare the efficacy of EDB and fat graft interposition in terms of filling the postresection gap. Foot pain was the most common presenting complaint, though limitation of activities, stiffness, preoperative hindfoot malalignment, and associated injuries were also frequently observed. One year after resection, 87% of the patients returned to sport or their past activities, whereas 5% had symptomatic regrowth requiring repeat resection. Seventy-four percent had improvement of subtalar motion and 82% had improvement of plantarflexion; which was identified as an additional clinical sign of a calcaneonavicular bar. Preoperative pain averaged 7 of 10, whereas postoperative pain averaged less than 1 of 10 at rest, while walking, and with activities. The cadaveric study showed that the EDB was able to fill on average only 64% of the resected gap, leaving approximately 10 mm of the plantar gap unfilled. Reossification and reoperation rates with fat graft interposition in our series were lower than in most published reports of EDB interposition. Ankle and subtalar motion improved in a vast majority of the patients, and most patients returned to sport without requiring further surgery. Resection of a calcaneonavicular coalition with interposition of fat graft, when meticulously performed, is an effective way to relieve symptoms, restore subtalar motion, and return patients to activities, while preventing reossification.

Calcaneonavicular Coalition Resection with Extensor Digitorum Brevis Interposition in Adults

Traditionally, pediatric patients with symptomatic calcaneonavicular coalitions have been treated with resection of the coalition and interposition of the origin of the extensor digitorum brevis muscle. Despite the success of calcaneonavicular coalition resection in children, many surgeons are reluctant to perform this procedure in adults or in patients with osseous coalitions, and joint sacrificing arthrodesis often is done instead. Seven adult patients (eight feet) had calcaneonavicular coalition resection with extensor digitorum brevis interposition. The average patient age was 41 years, and all patients displayed isolated, symptomatic calcaneonavicular coalitions without any radiographic evidence of degenerative arthritis. At followup, physical and radiographic evaluations were performed, and an American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score was recorded. Charts were reviewed for complications and patients were questioned with regards to their overall satisfaction with the surgery. At a mean postoperative followup of 56.5 months, the average AOFAS score was 87. Review of most recent radiographs revealed no degenerative changes or recurrence of the coalition. All patients responded that they would have this surgery again and that they would recommend this procedure to a friend. Complications included one superficial infection and one dysesthesia involving the sural nerve. The results of the present study suggest that resection combined with muscular interposition can be successful in patients over the age of 18 in whom conservative management of their symptomatic coalitions has failed. This procedure offers an excellent alternative to arthrodesis and has a very low complication rate.

Success of calcaneonavicular coalition resection in the adult population.

Twelve adult patients (13 feet), average age 33 years (range, 19-48 years), with calcaneonavicular coalitions remained symptomatic after a trial of conservative treatment. Surgical resections were performed. Before surgery, there was < 5 degrees of inversion/eversion in 11 patients, radiographic evidence of degenerative arthritis in 10 feet (77%), and talar beaking in 7 feet. At an average postoperative follow-up of 36 months, subjective relief of preoperative symptoms was achieved in all but two patients. Two patients required subsequent hindfoot arthrodesis. Resection of calcaneonavicular coalition in the adult can be successful and provides an option to arthrodesis after nonoperative methods have failed.

Excision of symptomatic coalition of the middle facet of the talocalcaneal joint.

From 1977 through 1984, nine patients who had ten persistently symptomatic coalitions of the middle facet of the talocalcaneal joint were treated with excision of the coalition and an autogenous free fat graft. Evaluation revealed five excellent, three good, one fair, and one poor result, with an average length of follow-up of forty-two months after surgery. The patient (one foot) with the fair result initially had a poor result until revision, at which time incomplete resection was documented. The patient (one foot) with the poor result initially had a fair result, but it deteriorated forty months postoperatively. Incomplete resection at the time of the initial operation was documented at the time of the second operation. Functional testing of these patients revealed results that were comparable with the results that have been reported after resection of calcaneonavicular coalition. [corrected]
