ABSTRACT

Objective:To investigate the efficacy of osteochondral fragment fixation using bioabsorbable pins for Hepple Ⅱ osteochondral lesions of the talus (OLT) in adolescents.Methods:Retrospective case analysis was used. The clinical data and follow-up results of 13 adolescent patients (13 feet) with Hepple Ⅱ OLT were all treated with osteochondral fragment fixation using bioabsorbable pins admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2017 to December 2021 were retrospectively analyzed. There were 7 males and 6 females, with 13 right feet. The age was (14.85±2.23) years old, ranged from 12 to 18 years old. According to the American orthopedic foot and ankle society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) and SF-36 score before operation and at the last follow-up were used to evaluate the efficacy and function of the patients. Measurement data with normal distribution were represented as mean ± standard deviation( ± s), and the comparison between groups was conducted using the t-test; The mearsurement data with skewness distribution were expressed by M( Q1, Q3), and rank-sum test was used for inter-group comparison. Results:Thirteen adolescent patients (13 feet) with Hepple Ⅱ OLT underwent surgery successfully and were followed up for (25.54±9.95) months. All wounds healed by first intention, and no complications such as wound infection and delayed healing occurred. Preoperative AOFAS ankle-posterior foot score, VAS and SF-36 score were 58.62±3.55, 7.00 (6.50, 8.00) and 68.38±4.81, respectively. At the last follow-up, the scores were 97.38±2.73, 1.00 (0.00, 1.00), 91.15±4.28, respectively, and the results were significantly improved at the last follow-up, with the difference between the two groups statistically significant( P<0.05). Conclusion:Osteochondral fragment fixation using bioabsorbable pins which can promote cartilage repair, significantly improve symptoms, and achieve better clinical satisfaction with fewer complications, is a safe and effective surgical treatment option for Hepple Ⅱ OLT in adolescents with satisfactory short-term clinical outcomes.

ABSTRACT

Objective:To study the morphology of dorsal medial talar neck osteophyte (DMTNO) and its association with anteromedial ankle impingement syndrome (AAIS) using CT 3D reconstruction images.Methods:The present retrospective study included 23 patients with AAIS due to DMTNO (case group) and 23 patients with DMTNO but without AAIS (control group) who had been admitted from February 2019 to June 2021. Multi-slice CT data (DICOM) of DMTNO in both groups were collected and imported into Arigin 3D Pro 3D reconstruction software to reconstruct and observe the 3D morphology of DMTNO. The dorsal convex distance, medial convex distance and anterior convex distance of DMTNO were measured to find their association with AAIS.Results:In the case group, DMTNO clearly showed a flat polyhedral shape with a large base and a small top; in the control group, DMTNO showed various shapes that were different mainly in an irregular top but similar in a large, long and narrow base. The dorsal convex distance [(8.07±2.30) mm] and medial convex distance [(6.70±2.62) mm] in the case group were significantly larger than those in the control group [(3.59±1.10) mm and (1.98±0.93) mm] ( P<0.05), but there was no significant difference between the 2 groups in the anterior convex distance ( P>0.05). Conclusions:The DMTNO leading to AAIS shows a flat polyhedral shape with a large base and a small top. No correlation is found between the anterior convex and AAIS whereas the dorsal convex and medial convex of DMTNO may be closely associated with AAIS.

ABSTRACT

Objective:To evaluate the mid-term efficacy of surgery for sub-acute injury to distal tibiofibular syndesmosis associated with ankle fracture.Methods:From July 2014 to October 2019, 14 patients were treated at Foot & Ankle Section, Department of Orthopaedics, Shanghai Sixth People’s Hospital for sub-acute injury to distal tibiofibular syndesmosis associated with ankle fracture.There were 11 males and 3 females, aged from 17 to 61 years (mean, 35.9 years).According to Danis-Weber classification, 6 cases were type B and 8 type C; according to Lauge-Hansen classification, 7 cases belonged to supination-external rotation, one to pronation-abduction, and 6 to pronation-external rotation (Maisonneuve fracture in 4).The syndesmosis injury was treated by fixation with distal tibiofibular screws in 11 cases, by Tightrope elastic fixation in one, by hybrid fixation with distal tibiofibular screws and Tightrope in one, and by distal tibiofibular fusion in one.Postoperative complications were recorded.Their visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society ankle-hindfoot scores (AOFAS-AH) were compared between preoperation and the last follow-up.Results:The 14 patients were followed up for 24 to 85 months (mean, 46.8 months). Of the 9 patients whose distal tibiofibular screws had been removed (including one with hybrid fixation), wound infection occurred in one after removal of all the internal fixation, distal tibiofibular widening in 2, ankle degeneration in 5 and fibular nonunion in one. Of the other 3 patients whose distal tibiofibular screws had not been removed, screw breakage happened in 2, screw loosening in one and distal tibiofibular widening in one. The VAS scores were significantly improved from preoperative 6.8±0.9 to 1.4±1.3 at the last follow-up; the AOFAS-AH scores were increased significantly from preoperative 35.3±6.3 to 86.8±11.7 at the last follow-up (both P<0.001). According to AOFAS-AH scores, 8 cases were excellent, 4 good and 2 moderate. Conclusion:Surgery for sub-acute injury to distal tibiofibular syndesmosis associated with ankle fracture can restabilize the distal tibiofibular syndesmosis and ankle joint, reduce pain and improve ankle function, leading to fine mid-term efficacy.

ABSTRACT

Objective:To investigate the efficacy of posterior ankle arthroscopic microfracture with platelet-rich plasma (PRP) injection for the treatment of posterior osteochondral lesions of the talus (OLT).Methods:A retrospective case series study was conducted on clinical data of 13 patients with posterior OLT admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University from September 2019 to October 2020. There were 10 males and 3 females, aged 10-65 years [(38.2±15.9)years]. According to Hepple′s classification, four patients were with type II, three with type IV, and six with type V. According to Elias′ grid scheme, nine patients were in zone 7 and four patients in zone 9. The disease duration was 13-51 months [(26.2±11.4)months]. All patients underwent posterior ankle arthroscopic microfracture with PRP injection. The operation time was recorded. The visual analogue scale (VAS), American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, and ankle range of motion (ROM) were compared before operation and at 3 months and 1 year after operation. The magnetic resonance observation of cartilage repair tissue (MOCART) score was used to evaluate the repair of cartilage injury at 1 year after operation. Complications were recorded.Results:All patients were followed up for 12-25 months [(15.7±3.7)months]. The operation time ranged from 50 to 90 minutes [(63.8±13.3)minutes]. The VAS improved from 3.0(3.0, 4.0)points before operation to 1.0(0, 2.0)points at 3 months after operation and 1.0(0,1.5)points at 1 year after operation; the AOFAS ankle-hindfoot score was improved from (66.1±11.8)points before operation to (84.8±9.5)points at 3 months after operation and (92.9±8.6)points at 1 year after operation; the ankle ROM was improved from (48.5±7.5)° before operation to (61.9±10.3)° at 3 months after operation and (65.4±11.8)° at 1 year after operation (all P<0.05). There was no significant difference in VAS at 3 months and 1 year after operation ( P>0.05). There were significant differences in AOFAS ankle-hindfoot score and ankle ROM at 3 months and 1 year after operation (all P<0.05). According to AOFAS ankle-hindfoot score, the results were excellent in 11 patients, good in one, and fair in one, with the excellent and good rate of 92%. The MOCART score was 40-85 points [(70.4±14.2)points] at 1 year after operation. There was no postoperative necrosis, infection or neurovascular injury. Two patients had slight transient pain during rehabilitation training and were improved after non-surgical treatment. Conclusion:For posterior OLT, posterior ankle arthroscopic microfracture with PRP injection can effectively alleviate pain, improve ankle function and repair cartilage damage, with satisfactory short-term efficacy.

ABSTRACT

Objective:To evaluate the short-term outcome of arthroscopic modified Brostr?m procedure plus minimally invasive calcaneal osteotomy for the treatment of chronic lateral ankle instability combined with subtle cavus foot.Methods:A retrospective cohort study was conducted to analyze the clinical data of 12 patients suffering chronic lateral ankle instability combined with subtle cavus foot admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University from November 2016 to November 2020, including 5 males and 7 females, aged 16-62 years [(40.3±15.1)years]. All patients were treated with arthroscopic modified Brostr?m procedure plus minimally invasive calcaneal osteotomy. The calcaneal pitch angle, Meary′s angle and medial cuneiform height on the foot weight-bearing lateral view plus calcaneus valgus angle on the hindfoot long axial view were compared to evaluate the improvement of bony structure and foot alignment preoperatively and at 3 months and 1 year postoperatively. At the same time, American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and visual analogue scale (VAS) were used to evaluate the improvement of ankle function and pain. Postoperative complications were also observed and recorded.Results:All patients were followed up for 1-3 years [(1.6±0.6)years]. The calcaneal pitch angle was decreased from (24.6±5.3)° preoperatively to (22.5±4.9)° at postoperative 3 months and (22.3±5.0)° at postoperative 1 year; the Meary′s angle was decreased from 6.6°(5.2°,7.6°) preoperatively to 2.5°(0.5°,3.8°) at postoperative 3 months and 2.1°(0.5°,3.2°) at postoperative 1 year; the medial cuneiform height was decreased from (24.3±5.3)mm preoperatively to (22.3±4.8)mm at postoperative 3 months and (22.3±4.6)mm at postoperative 1 year; the calcaneus valgus angle was increased from -7.1°(-10.3°,-5.9°) preoperatively to 2.3°(-2.5°,4.5°) at postoperative 3 months and 2.4°(-1.6°,3.8°) at postoperative 1 year (all P<0.01). However, there were no significant differences in the calcaneal pitch angle, Meary′s angle, medial cuneiform height, and calcaneus valgus angle at postoperative 3 months and 1 year (all P>0.05). AOFAS ankle-hindfoot score was increased from (66.8±8.7)points preoperatively to (81.0±5.9)points at postoperative 3 months and (88.6±3.6)points at postoperative 1 year (all P<0.01). According to AOFAS ankle-hindfoot score, the results were excellent in four patients and good in eight patients at postoperative 1 year, with the excellent and good rate of 100%. VAS was decreased from 2.5(2.0,4.0)points preoperatively to 2.0(1.3,2.8)points at postoperative 3 months and 1.0(0,2.0)points at postoperative 1 year (all P<0.01). There were significant differences in the AOFAS ankle-hindfoot score and VAS at postoperative 3 months and 1 year (all P<0.05). Wound malunion was seen in one patient, and healed with a dress changing. All patients had no complications such as vascular or nerve injury. There was no recurrence of malformation or joint instability during 1-year follow-up. Conclusion:For chronic lateral ankle instability combined with subtle cavus foot, arthroscopic modified Brostr?m procedure plus minimally invasive calcaneal osteotomy can stabilize ankle joint, correct hindfoot alignment, improve function and relieve pain.

ABSTRACT

Objective:To evaluate the clinical results of reduction and fixation via fibular osteotomy for treatment of old ankle fractures involving the posterior malleolus in middle-aged and elderly patients.Methods:A retrospective case series study was made for 13 middle-aged and elderly patients with old ankle fractures involving the posterior malleolus treated from July 2013 to March 2018 in Sixth People's Hospital Affiliated to Shanghai Jiao Tong University. There were 2 males and 11 females, with age of 48-63 years (mean, 54.8 years). The mean surgical period was 8-18 weeks from injury (mean, 9.6 weeks). According to Haraguchi classification, all posterior malleolar fractures were type I. According to Lauge-Hansen classification, there were 2 patients with pronation-external rotation type and 11 with supination-external rotation type. All patients underwent open reduction and fixation via fibular osteotomy. Bone healing time and postoperative complications were recorded. Clinical results were assessed by visual analogue scale (VAS) score and American orthopedic foot and ankle society (AOFAS) ankle-hind score.Results:All patients were followed up for average 20.3 months (range, 9-36 months). All patients had bone union, with the mean healing period of 12-15 weeks (average 14.8 weeks). No infection, implant loosening or breakage occurred after operation. X-ray film of one patient suggested mild traumatic arthritis. At the latest follow-up, VAS was improved to (1.0±0.2)points compared to pre-operative (5.3±0.6)points ( P<0.05), and the AOFAS ankle-hind score was improved to (85.2±7.4)points compared to pre-operative (42.4±6.7)points ( P<0.05). According to the AOFAS ankle-hind score, the results were excellent in 4 patients, good in 8, moderate in 1, with the excellent and good rate of 92%. Conclusion:For old ankle fractures involving the posterior malleolus in the middle-aged and elderly patients, reduction and fixation via fibular can reduce postoperative complications, facilitate bone healing, relieve ankle pain and improve function recovery.

ABSTRACT

Objective@#To compare instrumentation with 3D-printed patient-specific guides versus conventional techniques in supramalleolar osteotomy for varus ankle osteoarthritis.@*Methods@#A retrospective analysis was done of the 21 patients with varus ankle osteoarthritis who had been treated at Department of Orthopaedics, Shanghai JiaoTong University Affiliated Sixth People's Hospital from January 2017 to December 2018. They were divided into 2 groups by their treatment methods. In the 9 patients treated by instrumentation with 3D-printed patient-specific guides, there were 6 males and 3 females with an age of 54.6±8.6 years, 4 left and 5 right sides involved, and one case of Takakura stage 1, 3 cases of Takakura stage 2 and 5 cases of Takakura stage 3a. In the 12 patients treated by conventional techniques, there were 7 males and 5 females with an age of 53.0±6.5 years, 7 left and 5 right sides involved, and one case of Takakura stage 1, 5 cases of Takakura stage 2 and 6 cases of Takakura stage 3a. The 3D printed guide group and the conventional group were compared in terms of operation time, intraoperative blood loss and frequency of intraoperative fluoroscopy, tibial anterior surface angle (TAS), talar tilt angle (TT), and tibial lateral surface angle (TLS). The differences in TAS, TT and TLS between pre- and post-operation in the 3D printed guide group were also evaluated.@*Results@#There were no significant differences in the preoperative general data between the 2 groups (P>0.05), indicating they were comparable. All the patients were available for follow-up for an average of 7.8 months (from 3 to 15 months). The 3D printed guide group incurred significantly shorter operation time (106.2±10.6 min), less intraoperative blood loss (207.2±16.0 mL) and lower fluoroscopy frequency (2±0) than the conventional osteotomy group (all P<0.01). The post-operative TAS (94.3°±3.2°) and TT (3.8°±0.8°) angles in the 3D guide group were significantly different from their preoperative values (84.6°±3.5° and 7.6°±1.6°) (P<0.01). The 3D printed guide group was not significantly different from the conventional group in postoperative TAS (94.3°±3.2° versus 92.4°±5.9°), TT (3.8°±0.8° versus 4.2°±1.1°) or TLS (83.7°±3.4° versus 84.2°±2.2°) angles (P>0.05).@*Conclusions@#Compared with conventional techniques, instrumentation with 3D-printed patient-specific guides can shorten operation time and reduce intraoperative blood loss and fluoroscopy frequency. The 3D printed patient-specific guides in osteotomy can facilitate accurate correction of varus deformity, leading to similar efficacy compared with conventional osteotomy.

ABSTRACT

Objective@#To explore the diagnosis and treatment of head and neck Castleman′s disease (CD), and to improve the understanding of the disease.@*Methods@#The clinical data of 41 patients with head and neck CD treated from January 2007 to July 2017 in the First Affiliated Hospital of Zhengzhou University were analyzed retrospectively. The patients were divided into two groups: localized CD (LCD, n=27) and multicentric CD (MCD, n=14). The clinical manifestations, laboratory examinations, operations, pathological findings and follow-up data were analyzed.@*Results@#LCD was characterized by asymptomatic enlargement of the single lymph node with mild clinical symptoms. The main pathological type was hyaline vascular type, which can be cured by surgical treatment. MCD accompanied by fever 9 cases(64.3%), anemia 8 cases (57.1%), splenomegaly 7 cases (50.0%), respiratory symptoms 6 cases (42.9%), with multiple enlarged superficial and deep lymph nodes with pain, pleural effusion, and edema of lower extremity, C-reaction protein increased in 8 cases (57.1%), hypoproteinemia 8 cases(57.1%), globulin increased 7 cases (50.0%) and neutropenia 6 cases(42.9%). The main pathological type was plasma cell type in 7 cases (50.0%), and also there were 4 cases of hyaline vascular type and 2 cases of mixed type. Chemotherapy with or without rituximab was the main treatment. Most patients received complete or partial remission except for 2 patients who died of lung infection due to chemotherapy.@*Conclusions@#The diagnosis of head and neck CD depends on pathological examination. LCD shows mild symptoms and good prognosis after surgery. However, clinical manifestations of MCD are complex, with relatively poor prognosis after comprehensive treatment.

ABSTRACT

Objective To evaluate the clinical results of wedge osteotomy and subtalar arthrodesis for rockbottom malunion after calcaneal fracture.Methods From February 2014 to February 2015,9 cases of rockbottom malunion after calcaneal fracture were treated with wedged osteotomy and subtalar arthrodesis.They were 8 men and one woman,aged from 31 to 49 years (average,40.5 years).Weight-bearing X-rays were taken before surgery and at final follow-ups.Talar declination,lateral talocalcaneal angle,lateral talo-first metatarsal angle and B(o)hler's angle were used to evaluate correction of the malunion.The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and visual analogue scale (VAS) for pain were used to assess functional recovery.Results Eight of them were fully followed up for an average time of 30.6 months (from 27 to 38 months).All the osteotomy sites and subtalar joints obtained bony union after an average of 17.1 weeks (from 12 to 22 weeks).The talar declination was improved from 2.5° (from-6° to 13°) preoperatively to 13.2° (from 5° to 19°) postoperatively,the lateral talocalcaneal angle from-0.2° (from-15° to 10°) preoperatively to 20.2° (from 7° to 25°) postoperatively,the talo-first metatarsal angle from 21.1° (from 10° to 30°) preoperatively to 9.9° (from 5° to 14°) postoperatively,and the calcaneal B(o)hler' s angle from-25.6° (from-39° to-10°) preoperatively to 22.4° (from 10° to 35°) postoperatively.The AOFAS score averaged 26.6° (from 12 to 53) preoperatively and 79.7 (from 72 to 89) at the final follow-up;the VAS score averaged 7.5 (from 6 to 9) preoperatively and 2.6 (from 2 to 3) at the final follow-up.Both scores demonstrated improvements after operation.Conclusions Since the pathoanatomy of rockbottom malunion after calcaneal fracture consist in severe loss of calcaneal height,resulting in horizontalization of the talus and anterior ankle impingement,wedge osteotomy and sutalar arthrodesis can effectively correct the malunion,restore the loss of calcaneal height and hindfoot malalignment,and relieve the symptoms.

ABSTRACT

[Objective]To evaluate the clinical result of Weil osteotomy for refer metatarsalgia in hallux valgus. [Method]Between 2004 and 2005, 25 feet of 17 patients with hallux valgus were treated by osteotomy at the base of the first metatarsal and Weil osteotomy of the lesser metatarsal with metatarsalgia. Weight-bearing anterior-posterior and lateral X ray were taken before the surgery and 6 weeks after surgery on follow up. The hallux valgus angle , the intermetatarsal angle between 1st and 2nd metatarsal, and length of the second metatarsal were measured on the X-ray film. AOFAS system was used to judge the clinical result of the surgery. [Result]The hallux valgus before surgery angle was 32??5.7?,after surgery it was 12.8??3.5?; the intermetatarsal angle between lst and 2nd metatarsal before surgery was 24.2??3.7?,after surgery it was 10.5??0.7?; AOFAS score was 45.6?6.9 before surgery , and 86.9?4.6 after surgery ; significant difference was found between the result. The metatarsal after Weil osteotomy was shorten by 3~8 mm, mean 4.5 mm. After surgery 18 feet had pain free, and 7 feet had a signigicant pain relief . All the patient could return to normal life without other treatment. [Conclusion ] The biomechanical changes in the foot with hallux valgus should be analyzed before surgery . Combined use of base osteotomy at the first metatarsal and Weil osteotomy at lesser metatarsal can get satisfactory clinical result in patients with sever hallux valgus and transferred refer metatarsalgia.
