Objective To evaluate the results of arthroscopically-assisted closed reduction and percutaneous screw fixation by posterior approach to subtalar joint for calcaneal fractures of Essex-Lopresti tongue type, Sanders IIA, IIB, and IIIAB. Methods Sixteen patients with unilateral calcaneal fracture were treated with arthroscopically-assisted closed reduction and percutaneous screw fixation by posterior approach to subtalar joint between June 2012 and June 2015. There were 13 males and 3 females with an average age of 37.8 years (range, 18-65 years). The injury causes included falling from height in 10 cases and traffic accident in 6 cases. Of 16 cases, 4 were classified as Essex-Lopresti tongue type, 5 as Sanders IIA, 4 as Sanders IIB, and 3 as Sanders IIIAB. The interval of injury and operation was 4-8 days (mean, 5.94 days). The Böhler angle, Gissane angle, and width of calcaneus were measured before and after operation. American Orthopaedic Foot and Ankle Society (AOFAS) score was used to evaluate the ankle function at 12 months after operation. Results Primary healing of incision was obtained in all cases, and no complications of infection, necrosis, and osseous fascia compartment syndrome occurred. The patients were followed up 12-15 months (mean, 13.63 months). The X-ray films showed that fracture line disappeared at 6 months after operation; the patients had no tenderness or percussion pain, no breakage or loosening of internal fixation, no varus calcaneus tuberosity, no subtalar joint fusion, and no compression symptoms of peroneal tendons. Achilles tendon irritation occurred in 2 cases, and disappeared after removal of internal fixation; traumatic arthritis occurred in 2 cases, and was relieved after removal of internal fixation. The Böhler angle, Gissane angle, and calcaneal width were significantly improved at 3 days and 6 months after operation when compared with preoperative ones (P<0.05). The loss of the above indexes was observed at 6 months, showing no significant difference between at 3 days and 6 months (P>0.05). The AOFAS score results were excellent in 11 cases, good in 3 cases, and fair in 2 cases, and the excellent and good rate was 87.5%. Conclusion It has the advantages of little trauma, less complication, and good function recovery to use arthroscopically-assited closed reduction and percutaneous screw fixation by posterior approach to subtalar joint for calcaneal fractures of Essex-Lopresti tongue type, Sanders IIA, Sanders IIB, and Sanders IIIAB.
ObjectiveTo investigate the effectiveness of closed reduction and internal fixation with elastic nails in treatment of Mason type Ⅱ radial head fracture in adults.MethodsA clinical data of 28 patients with Mason type Ⅱ radial head fractures between May 2013 and March 2017 was retrospectively analyzed. Thirteen patients were treated with closed reduction and internal fixation with elastic nails (trial group); 15 patients were treated with open reduction and internal fixation with Herbert screws (control group). There was no significant difference in gender, age, cause of injury, side of fracture, and the time from injury to operation between the two groups (P>0.05). The operation time, blood loss, and fluoroscopy times in the two groups were recorded and compared. Postoperative X-ray films were used to evaluate the bone healing, heterotopic ossification, and necrosis of radial head. The effectiveness was evaluated according to Mayo score criteria of the elbow at last follow-up. ResultsAll patients were followed up 12-30 months (mean, 21.9 months). The operation time and blood loss were significantly less in the trial group than in the control group (P<0.05), while the fluoroscopy times significantly increased in the trial group than in the control group (P<0.05). X-ray films showed that all fractures healed with the bone healing time of (2.85±0.69) months in the trial group and (3.35±0.88) months in the control group. There was no significant difference in bone healing time between the two groups (t=1.654, P=0.110). Heterotopic ossification occurred in 2 cases in the control group. At last follow-up, there was no significant difference in the Mayo scores between the trial group (90.6±5.3) and the control group (86.4±7.1) (t=1.750, P=0.092).ConclusionClosed reduction and internal fixation with elastic nails, as a minimally invasive technique, has advantages of short operation time and less bleeding in the treatment of Mason type Ⅱ radial head fracture.
Objective To investigate the effectiveness of medial and lateral column periosteal hinge reconstruction using Kirschner wire in the closed reduction of multi-directional unstable humeral supracondylar fractures in children. Methods A clinical data of 43 children with multi-direction unstable humeral supracondylar fractures, who met the selection criteria and were admitted between August 2020 and August 2022, was retrospectively analyzed. Twenty-one cases of fractures were treated wuth closed reduction after medial and lateral column periosteal hinge reconstruction using Kirschner wire and percutaneous Kirschner wires fixation (study group), while 22 cases of fractures were treated by traditional closed reduction technique and percutaneous Kirschner wire fixation (control group). There was no significant difference in gender, age, cause of injury, fracture side, and interval from injury to operation between the two groups (P>0.05). The operation time, intraoperative fluoroscopy times, the number of children who were changed to open reduction after closed reduction failure, fracture healing time, complications within 2 months after operation, and the Flynn score of elbow joint function at last follow-up were compared between the two groups. ResultsAll the fractures in the study group were successfully closed reduction, and 4 cases in the control group were changed to open reduction and completed the operation, the difference between the two groups was significant (P=0.040). The operation time and intraoperative fluoroscopy times of the study group were significantly less than those of the control group (P<0.05). All children in both groups were followed up 6-18 months with an average of 9.0 months in the study group and 9.8 months in the control group. Imaging review showed that the fractures of both groups healed, and the difference in the healing time between the two groups was not significant (P=0.373). According to Flynn score at last follow-up, the excellent and good rate of elbow joint function was 95.2% (20/21) in the study group and 86.4% (19/22) in the control group, with no significant difference (P=0.317). There was no complication such as infection or irritation at the end of Kirchner wire within 2 months after operation. Conclusion For children with multi-directional unstable humeral supracondylar fractures, the use of Kirschner wires to reconstruct the medial and lateral column periosteal hinge to assist in closed reduction has the advantages of shortening operation time, reducing intraoperative fluoroscopy times, and effectively reducing the incidence of open reduction, and can achieve similar postoperative elbow joint function when compared with traditional closed reduction technique.
Objective To investigate the short-term effectiveness of transverse antecubital incision in the treatment of failed closed reduction of Gartland type Ⅲ supracondylar humeral fractures (SHFs) in children. Methods Between July 2020 and April 2022, 20 children with Gartland type Ⅲ SHFs who failed in closed reduction were treated with internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision. There were 9 boys and 11 girls with an average age of 3.1 years (range, 1.1-6.0 years). The causes of injuries were fall in 12 cases and fall from height in 8 cases. The time from admission to operation ranged from 7 to 18 hours, with an average of 12.4 hours. The healing of the incision and the occurrence of complications such as nerve injury and cubitus varus were observed after operation; the elbow flexion and extension range of motion after removing the gypsum, after removing the Kirschner wire, and at last follow-up were recorded and compared, as well as the elbow flexion and extension and forearm rotation range of motion at last follow-up between healthy and affected sides; the Baumann angle was measured on the X-ray film, and the fracture healing was observed. At last follow-up, the effectiveness was evaluated according to the Flynn elbow function evaluation criteria. ResultsAll incisions healed by first intention, and there was no skin necrosis, scar contracture, ulnar nerve injury, and cubitus varus. Postoperative pain occurred in the radial-dorsal thumb in 2 cases. The gypsum was removed and elbow flexion and extension exercises were started at 2-4 weeks (mean, 2.7 weeks) after operation, and the Kirschner wire was removed at 4-5 weeks (mean, 4.3 weeks). All the 20 patients were followed up 6-16 months, with an average of 12.4 months. The fracture healing time was 4-5 weeks, with an average of 4.5 weeks, and there was no complication such as delayed healing and myositis ossificans. The flexion and extension range of motion of the elbow joint gradually improved after operation, and there were significant differences between the time after removing the gypsum, after removing the Kirschner wire, and at last follow-up (P<0.017). There was no significant difference in the flexion and extension of the elbow joint and the forearm rotation range of motion between the healthy and affected sides at last follow-up (P>0.05). There was no significant difference in Baumann angle between the time of immediate after operation, after removing the Kirschner wire, and at last follow-up (P>0.05). According to Flynn elbow function evaluation standard, 16 cases were excellent and 4 cases were good, the excellent and good rate was 100%. Conclusion The treatment of Gartland type Ⅲ SHFs in children with failed closed reduction by internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision has the advantages of complete soft tissue hinge behind the fracture for easy reduction and wire fixation, small incision, less complications, fast fracture healing, early functional recovery, reliable reduction and fixation, and can obtain satisfactory results.
Objective To evaluate the effectiveness of double joystick technique assisted closed reduction and Kirschner wire internal fixation in the treatment of Gartland type Ⅲ supracondylar fractures of the humerus (SCFH) in children. Methods A retrospective study was conducted on 28 cases of Gartland type Ⅲ SCFH with complete data available, who underwent closed reduction and Kirschner wire internal fixation with the double joystick technique between August 2022 and July 2024. There were 23 boys and 5 girls, with an average age of 6.4 years (range, 1-12 years). All fractures resulted from falls and were classified as extension-type. X-ray film showed the radial displacement of the distal fragment in 15 cases and unlar displacement in 13 cases. The interval from injury to operation was 3-36 hours (mean, 19.5 hours). X-ray film re-examination was conducted to evaluate the fracture healing, and the Baumann angle of affected elbow joint and carrying angle of bilateral elbow joints were measured. Elbow joint function was evaluated using the range of motion (flexion and extension) and the Flynn criteria. The above indicators were compared between affected and healthy sides. Results All operation were successfully completed. The operation time ranged from 15 to 40 minutes (mean, 25.2 minutes). The length of hospital stay was 2-5 days (mean, 3.5 days). All patients were followed up 3-24 months (mean, 11.8 months). X-ray film confirmed fracture healing in all patients, with a mean healing time of 5.4 weeks (range, 4-6 weeks). At last follow-up, the Baumann angle of the affected elbow joint was (73.50±3.46)°, and the carrying angle and the range of motion in flexion and extension of the affected elbow joint were significantly less than the contralateral side (P<0.05). According to the Flynn criteria, the elbow joint function of the affected elbow was evaluated as excellent in 25 cases and good in 3 cases, with an excellent and good rate of 100%. Conclusion The double joystick technique is a safe and effective method which can facilitate the closed reduction and Kirschner wire internal fixation of Gartland type Ⅲ SCFH in children without increasing risk of complications.
ObjectiveTo investigate the effectiveness and advantages of skeletal tractor in closed reduction and proximal femoral nail antirotation (PFNA) internal fixation of intertrochanteric fracture compared with traction table.MethodsThe clinical data of 86 patients with intertrochanteric fractures, who were treated with closed reduction and PFNA internal fixation between October 2016 and March 2018 and met the selection criteria, was retrospectively analysed. Among them, 44 cases were treated with skeletal tractor (trial group) and 42 cases were treated with traction table (control group). There was no significant difference between the two groups in gender, age, cause of injury, fracture side, AO classification, and degree of osteoporosis (P>0.05). The preoperative position time, operation time, intraoperative fluoroscopy times, intraoperative blood loss, fracture healing time, intraoperative and postoperative complications, and postoperative Harris score were compared between the two groups.ResultsThe operation was successfully completed in both groups. Compared with the control group, the patients in the trial group had shorter preoperative position time and operation time, fewer intraoperative fluoroscopy times, and less intraoperative blood loss (P<0.05). The patients were followed up 12-21 months in trial group (mean, 14.2 months) and 12-22 months in control group (mean, 14.3 months). Venous thrombosis of lower extremity occurred in 8 patients (3 cases of trial group and 5 cases of control group) after operation. Internal fixation failure occurred in 5 patients (2 cases of trial group and 3 cases of control group) during 1 year after operation. All fractures healed except for those with internal fixation failure, the fracture healing time was (11.6±2.9) weeks in trial group and (12.4±3.6) weeks in control group; and there was no significant difference between the two groups (t=1.250, P=0.214). At 1 year after operation, Harris score of the trial group was 86.2±5.9 and that of the control group was 84.1±6.1. There was no significant difference between the two groups (t=1.768, P=0.080).ConclusionCompared with traction table, skeletal tractor in closed reduction and PFNA internal fixation of intertrochanteric fracture can significantly shorten the preoperative position time and operation time, reduce the intraoperative fluoroscopy times, improve the operation efficiency, and have similar effectiveness.
Objective To investigate the surgical technique and preliminary effectiveness of closed reduction and internal fixation (CRIF) using antegrade elastic intramedullary nailing (ESIN) via a novel approach through the proximal radius for treating distal radius metaphyseal-diaphyseal junction (DRMDJ) fractures in children. Methods A retrospective analysis was conducted on 34 children with DRMDJ fractures who met the selection criteria and were treated between January 2020 and June 2023. There were 21 boys and 13 girls, aged 6-14 years (mean, 8.2 years). Injury causes included falls in 11 cases and sports-related trauma in 23 cases. Twenty-six cases were associated with ipsilateral distal ulnar fractures. All patients had failed initial closed reduction in the outpatient clinic. The time from injury to operation ranged from 1 to 15 days (mean, 4 days). All patients underwent CRIF using antegrade ESIN inserted via a novel approach at the proximal one-third of the radius. The operation time, intraoperative fluoroscopy frequency, fracture healing time, and complications were recorded. Fracture reduction was assessed immediately after operation on anteroposterior and lateral X-ray films for residual translation and angulation. Wrist function was evaluated using the modified Mayo wrist score. ResultsSurgery was successfully completed in all 34 children. CRIF with ESIN failed in 2 cases with associated ipsilateral distal ulnar fractures, requiring conversion to open reduction of the ulna. Operation time ranged from 15 to 56 minutes (mean, 21 minutes). Intraoperative fluoroscopy frequency ranged from 5 to 21 times (mean, 7 times). Immediate postoperative X-ray films showed residual translation of 0-15% on anteroposterior view and 0-10% on lateral view, and residual angulation of 0°-5° on both anteroposterior and lateral views. All children were followed up 6-18 months (mean, 12 months). There was no complication such as neurovascular injury, incision infection, or limitation of forearm rotation. Follow-up X-ray films showed no fracture displacement, implant loosening, delayed union, or nonunion. Fracture healing time ranged from 4 to 8 weeks (mean, 6 weeks). Implants were removed at 4-6 months postoperatively (mean, 5 months). At last follow-up, all fractures had achieved anatomic or near-anatomic healing. The modified Mayo wrist score ranged from 80 to 100 (mean, 94), with 27 excellent and 7 good results, yielding an excellent and good rate of 100%. Conclusion CRIF using antegrade ESIN via a novel approach through proximal radius is a safe and effective treatment for pediatric DRMDJ fractures, associated with few postoperative complications and excellent restoration of wrist function.
Objective To compare the effectiveness of ultrasound-guided closed reduction with Kirschner wire fixation and open reduction with Kirschner wire fixation in the treatment of humeral lateral condyle fracture (HLCF) in children. Methods A clinical data of 53 children with HLCF admitted between May 2020 and April 2023 and met selective criteria was retrospectively analyzed. Of these, 25 cases were managed with closed reduction and Kirschner wire fixation under ultrasound guidance (closed group), while 28 cases underwent open reduction and Kirschner wire fixation (open group). There was no significant difference between the two groups in terms of gender, age, cause of injury, fracture side, fracture classification, and time from injury to operation (P>0.05). The following variables were recorded and compared between the two groups: operation time, intraoperative fluoroscopy frequency, fracture healing time, incidence of complications, and the Flynn elbow function score at last follow-up. Results In the closed group, the fractures were successfully reduced under ultrasound guidance, with no nerve damage reported in either group. The operation time and intraoperative fluoroscopy frequency were significantly less in the closed group than in the open group (P<0.05). One case of infection (Kirschner wire irritation) was observed in the closed group, while 3 cases in the open group (2 of Kirschner wire irritation and 1 of incision infection). However, the difference in the incidence of infection between the two groups was not significant (P>0.05). All patients in both groups were followed up 6-18 months (mean, 10.2 months). X-ray examinations confirmed that fractures had healed in both groups, with no significant difference in healing time (P>0.05). During follow-up, 5 cases of lateral humeral process formation were observed in the closed group, compared to 12 cases in the open group, although this difference was not significant (P>0.05). At last follow-up, the excellent and good rate of elbow joint function was evaluated as 96.0% (24/25) in the closed group and 92.9% (26/28) in the open group according to the Flynn scoring criteria, with no significant difference between the two groups (P>0.05). Both groups showed no occurrence of ossifying myositis or elbow internal/external rotation. Conclusion The effectiveness of ultrasound-guided closed reduction and Kirschner wire fixation in the treatment of HLCF in children is comparable to open reduction and Kirschner wire fixation, but the former can reduce operation time and intraoperative fluoroscopy frequency, and obtain lower the incidence of complications.
Objective To investigate the effectiveness of one-stage closed reduction and elastic compression fixation with double Kirschner wires for Wehbe-Schneider types ⅠB and ⅡB bony mallet fingers. Methods Between May 2017 and June 2020, 21 patients with Wehbe-Schneider type ⅠB and ⅡB bony mallet fingers were treated with one-stage closed reduction and elastic compression fixation using double Kirschner wires. There were 15 males and 6 females with an average age of 39.2 years (range, 19-62 years). The causes of injury were sports injury in 9 cases, puncture injury in 7 cases, and sprain in 5 cases. The time from injury to admission was 5-72 hours (mean, 21.0 hours). There were 2 cases of index finger injury, 8 cases of middle finger injury, 9 cases of ring finger injury, and 2 cases of little finger injury. The angle of active dorsiflexion loss of distal interphalangeal joint (DIPJ) was (40.04±4.02)°. According to the Wehbe-Schneider classification standard, there were 10 cases of typeⅠB and 11 cases of type ⅡB. The Kirschner wire was removed at 6 weeks after operation when X-ray film reexamination showed bony union of the avulsion fracture, and the functional exercise of the affected finger was started. Results The operation time was 35-55 minutes (mean, 43.9 minutes). The length of hospital stay was 2-5 days (mean, 3.4 days). No postoperative complications occurred. All patients were followed up 6-12 months (mean, 8.8 months). X-ray films reexamination showed that all avulsion fractures achieved bony union after 4-6 weeks (mean, 5.3 weeks). Kirschner wire was removed at 6 weeks after operation. After Kirschner removal, the visual analogue scale (VAS) score of pain during active flexion of the DIPJ was 1-3 (mean, 1.6); the VAS score of pain was 2-5 (mean, 3.1) when the DIPJ was passively flexed to the maximum range of motion. The angle of active dorsiflexion loss of affected finger was (2.14±2.54)°, showing significant difference when compared with preoperative angle (t=52.186, P<0.001). There was no significant difference in the active flexion angle between the affected finger (79.52±6.31)° and the corresponding healthy finger (81.90±5.36)° (t=1.319, P=0.195). At 6 months after operation, according to Crawford functional evaluation criteria, the effectiveness was rated as excellent in 11 cases, good in 9, and fair in 1, with an excellent and good rate of 95.24%. Conclusion For Wehbe-Schneider typesⅠB and ⅡB bony mallet fingers, one-stage closed reduction and elastic compression fixation with double Kirschner wires can effectively correct the deformity and has the advantages of simple surgery, no incision, and no influence on the appearance of the affected finger.
ObjectiveTo compare the effectiveness of ultrasound-guided closed reduction and Kirschner wire fixation for different unstable humeral lateralcondylar fractures of children. Methods The clinical data of 94 children with unstable humeral lateralcondylar fractures admitted to three medical centers between January 2021 and October 2022 were retrospectively analyzed. The children were divided into three groups according to the Song classification and whether the elbow joint was dislocated or not, including 42 cases of Song 4 type (group A), 38 cases of Song 5 type (group B), and 14 cases of elbow joint dislocation (group C). There was no significant difference in gender, age, side, cause of injury, and time from injury to operation among the three groups (P>0.05). All children were treated with ultrasound-guided closed reduction and Kirschner wire fixation. The operation time and complications of the three groups were recorded and compared, and the failure of closed reduction was evaluated by ultrasound. X-ray examination was performed at last follow-up to measure the Baumann angle, condylar angle, carrying angle, and lateral osteophyte of the affected side; the extension, flexion, pronation, and supination range of motion of the affected elbow joint were measured; the function of the elbow joint was evaluated by Mayo score. ResultsThe operation time in group A was significantly longer than that in groups B and C (P<0.05). There were 7, 2, and 5 cases of closed reduction failure in groups A, B, and C, respectively, and there was no significant difference in the incidence of the closed reduction failure (P>0.05). All patients were followed up 6-28 months, with an average of 15.7 months. There was no significant difference in the follow-up time among the three groups (P>0.05). Complications: in group A, there were 2 cases of delayed union, 4 cases of needle tract infection, 1 case of trochlear necrosis, and 39 cases of lateral osteophyte; in group B, there was 1 case of malunion, 5 cases of needle tract infection, 1 case of redisplacement, and 26 cases of lateral osteophyte; in group C, there were 2 cases of needle tract infection and 10 cases of lateral osteophyte. There was no significant difference in the incidence of complications among the three groups (P>0.05). No cubitus varus or cubitus valgus deformity was found in all patients. At last follow-up, except that the condylar angle in group A was significantly greater than that in groups B and C (P<0.05), there was no significant difference in other imaging indicators, elbow range of motion, or Mayo score between groups (P>0.05). ConclusionThe Song type 4 of humeral lateralcondylar fracture treated with ultrasound-guided closed reduction and Kirschner wire fixation has a longer operation time, more postoperative complications, and is more prone to lateral osteophyte.
