ABSTRACT
Objective:To evaluate the outcomes of endoscopic resection of symptomatic talocalcaneal coalitions in adolescents using a posterior approach.Methods:A retrospective case-series study was performed to analyze the data of 15 adolescent patients (16 feet) with symptomatic talocalcaneal coalitions (TCC) who had been treated by posterior arthroscopy from February 2017 to December 2020 at Department of Orthopaedics, Xuzhou Central Hospital. There were 11 boys and 4 girls with an average of 14.3 years (from 11 to 17 years). The left side was affected in 9 and the right side in 5 patients, and both sides were involved in one. Ten patients had a history of ankle sprain. The clinical outcomes were evaluated by visual analogue scale (VAS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score and 36-item short form health survey (SF-36) postoperatively.Results:The 15 patients were followed up for a mean time of 19.9 months (from 12 to 36 months). At the final follow-up, the VAS significantly decreased from preoperative 6 (6, 7) points to 1 (1, 3) point, the AOFAS ankle-hindfoot score significantly increased from preoperative (54.1±10.4) points to (90.0±16.6) points, and the SF-36 score significantly improved from preoperative (55.5±12.7) points to (88.7±6.5) points ( P<0.05). Follow-ups found such complications as infection, TCC recurrence or osteoarthritis in none of the patients. Conclusion:Endoscopic TCC resection using a posterior approach is an effective surgery for symptomatic TCC in adolescents, showing advantages of limited invasion, fast recovery, a low rate of postoperative complications and precise resection.
ABSTRACT
Objective To evaluate Evans lateral lengthening calcaneal osteotomy(E-LLCOT) in the treatment oftalocalcaneal coalitions (TCCs) with forefoot abduction deformity in the teenagers.Methods From February 2014 to August 2018,11 teenaged patients (14 feet) were treated at Department of Foot and Ankle Surgery,Zhengzhou Orthopaedics Hospital for TCCs with severe forefoot abduction deformity.They were 6 males (8 feet) and 5 females (6 feet),aged from 13 to 17 years (average,15 years).Their diseases involved bilateral feet in 3 cases and unilateral foot in 8,the left foot in 7 cases and the right in 7.All patients underwent TCCs resection followed by E-LLCOT.Their talonavicular coverage angles (TCA) and talar-second metatarsal angles (T2-MT) on the anteroposterior film and talar horizontal angles (TH) and talar-first metatarsal angles (T1-MT) on the lateral film were measured preoperatively and at the last follow-up.The foot functions were evaluated preoperatively and at the last follow-up using the ankle-hindfoot scores of American Orthopaedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS).Results All the 11 patients were followed up for 12 to 24 months (average,16.5 months).The mean preoperative TCA (22.3°,from 20° to 26°) was improved to 10.5° (from 8° to 13°) at the last follow-up;the mean T-2MT was improved from preoperative 17.6° (from 16° to 20°) to 6.5° (from 5° to 11°) at the last follow-up;the mean TH on the lateral view was improved from preoperative 35° (from 25° to 40°) to 17.5° (from 16° to 21°) at the last follow-up;the mean T-1MT was improved from preoperative 15.5° (from 10° to 22°) to 3.5° (from 2° to 6°) at the last follow-up;the mean AOFAS score was improved from 56.5 (from 50 to 62) preoperatively to 90.6 (from 75 to 95) at the last follow-up;the mean VAS score was improved from 6.0 (from 5 to 7) preoperatively to 2 (from 0 to 3) at the last follow-up.Conclusion For TCCs with severe forefoot abduction deformity in the geenagers,E-LLCOT after TCCs resection can effectively correct deformity,relieve pain and achieve significant functional and radiographic improvements.
ABSTRACT
Objective: To investigate the effectiveness of arthroscopic talocalcaneal coalition resection in painful adults via a modified posterior approach. Methods: Between January 2015 and December 2017, 9 patients with painful talocalcaneal coalition accepted arthroscopic resection via the posterior malleolus high lateral observation approach combined with the lower medial operation approach. Of them, 6 were male and 3 were female, aged from 19 to 30 years (mean, 24 years). Among them, 2 cases had no definite local trauma and 7 cases had a history of sprain of foot and ankle. The disease duration ranged from 6 to 30 months, with a median of 12 months. Rozansky classification of talocalcaneal coalition for the 9 patients: 5 cases (5 feet) were type Ⅰ, 2 cases (2 feet) type Ⅱ, and 2 cases (2 feet) type Ⅲ. The patients had no sequelae of limb dysfunction and no limb joint surgery in the past. All the patients received anteroposterior and lateral X-ray films and CT scans of the ankle joint during follow-up. The visual analogue scale (VAS) score and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score were used to evaluate the effectiveness. Results: The operation time was 60-90 minutes (mean, 76 minutes). All patients were followed up 12-24 months (mean, 18 months). All the incisions healed by first intention, without infection, skin necrosis, lower extremity deep vein thrombosis, vascular nerve and tendon injury, bone bridge recurrence, and other complications. The ankle function recovered well and the pain was relieved obviously after operation, and the patients returned to work at 3-5 months after operation, with an average of 3.9 months. At last follow-up, the VAS score was 0.7±0.5, which was significantly improved ( t=20.239, P=0.000) when compared with preoperative score (4.2±0.5); the AOFAS ankle-hind foot score was 94±4, which was significantly improved ( t=-27.424, P=0.000) when compared with preoperative score (62±2). According to AOFAS ankle-hindfoot scoring system, the results were excellent in 7 cases and good in 2 cases at last follow-up. Conclusion: It is more intuitive, more space, and more flexibility for operation via the modified posterior malleolus high lateral observation approach combined with the lower medial operation approach in talocalcaneal coalition. It is feasible to remove talocalcaneal coalition programmatically according to the specific anatomic signs during the operation.
ABSTRACT
Objective: To investigate the effectiveness of the Evans lateral lengthening calcaneal osteotomy (E-LLCOT) in treatment of talocalcaneal coalition (TCC) with hindfoot valgus deformity. Methods: Between January 2014 and October 2017, 10 patients (13 feet) of TCC with hindfoot valgus deformities underwent E-LLCOTs. There were 6 males (8 feet) and 4 females (5 feet) with an age of 13-18 years (mean, 15.8 years). The disease duration was 10-14 months (mean, 11.5 months). The foot deformity was characterized by hindfoot valgus, forefoot abduction, and collapse of the medial arch. Pain site was the tarsal sinus in 4 feet, TCC in 5 feet, and ankle joint in 4 feet. There were tightness of the gastrocnemius in 3 cases (4 feet) and Achilles tendon in 7 cases (9 feet) on Silverskiold test. The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was 46.54±9.08 and visual analogue scale (VAS) score was 6.54±0.88 after walking 1 kilometer. The AOFAS ankle-hindfoot score and VAS score were adopted to evaluate the postoperative function of the foot. The talar-first metatarsal angle (T1MT), talonavicular coverage angle (TCA), talar-horizontal angle (TH), calcaneal pitch angle (CP), and heel valgus angle (HV) were measured after operation. Results: All incisions healed by first intention. All patients were followed up 12-30 months (mean, 18 months). At last follow-up, the AOFAS ankle-hindfoot score and VAS score were 90.70±6.75 and 1.85±0.90, respectively, showing significant differences when compared with preoperative scores ( t=-23.380, P=0.000; t=35.218, P=0.000). X-ray films showed that the osteotomy healed at 2-4 months (mean, 3 months) after operation. At last follow-up, the T1MT, TCA, TH, and HV were significantly lower than preoperative ones ( P<0.05), and the CP was significantly higher than preoperative one ( P<0.05). During the follow-up, the pain did not relieve obviously in 1 patient (1 foot), and the cutaneous branch of the sural nerve injured in 1 patient (1 foot). Conclusion: For TCC with severe hindfoot valgus deformity, E-LLCOT can effectively correct deformity and relieve pain.

ABSTRACT
Talocalcaneal coalition known as the most common tarsal coalition is a congenital failure of segmentation. Talocalcaneal coalition with complete bone bridge is very rare, and there are few references in the literature about the clinical results and the operative method for this type of tarsal coalition. We report a case of 15 years old female with complete talocalcaneal coalition, who showed good clinical results by lateral sliding calcaneal osteotomy.

PURPOSE: Study was to evaluate the operative results for tarsal coalition with tarsal tunnel syndrome. MATERIALS AND METHODS: From Jan. 2005 to Mar. 2006, among a number of patients who were diagnosed with tarsal tunnel syndrome caused by tarsal coalition and treated surgically, 5 patients were closely observed for more than 12 months. All cases were talocalcaneal coalition and there were two male and three female patients with a mean age of 36 years (22-50 years). We used the Takakura rating scale as clinical evaluation. RESULTS: All five patients had a burning pain in the sole or extended to toes and showed positive Tinel's sign. Sensory disturbances were observed in the distribution of the medial plantar nerves in four patients and in the area of the medial and lateral plantar nerves in one. Atrophy and weakness of the plantar muscles were seen in two patients. The mean Takakura scale in preoperative and postoperative was 3.4 points (1 to 5 points), 8.6 point (6 to 10 points). The mean follow up was 14.4 months (12 to 16 months). The postoperative results were excellent in two patients, good in two and fair in one. As postoperative complications, there were persistent swelling in one patient and a flexion disturbance of Hallux in one. CONCLUSION: The coalition resection performed on tarsal tunnel syndrome caused by tarsal coalition could improve a level of pains and neurological symptoms significantly. However, since there were some undesirable complications, a detailed explanation to patients is required prior to surgical treatment and study of such complications may be required.
