UNASSIGNED: This retrospective study aimed to compare the clinical outcomes and complications of conventional tension band wire (TBW), TBW with penetrating technique, and double-bending technique.
UNASSIGNED: A total of 40 patients (17 men and 23 women; mean age: 64.0 ± 19.0 years) who underwent surgery for displaced olecranon fractures between January 2018 and December 2021 were included and divided into three groups based on the surgical method used (group A, conventional TBW; group B, TBW with penetrating technique; and group C, double-bending technique). Thirteen patients were assigned to group A, 17 to group B, and 10 to group C, including 2 Mayo type IB, 30 Mayo type IIA, and 8 Mayo type IIB fractures. Postoperative outcomes (elbow extension and flexion arc) and complications, such as backing out of the Kirschner wire (K-wire), were retrospectively evaluated.
UNASSIGNED: No significant difference was found in the general characteristics of the patients and fracture type among the three groups. The mean elbow extension arc values were 6.2°, 10.9°, and 0° in groups A, B, and C, respectively; it was significantly better in group C than in group B (P = .001). The rates of backing out of the K-wire were 84.6% (11/13) in group A, 41.2% (7/17) in group B, and 0% (0/10) in group C; the rate was significantly lower in group C than in group A (P < .001).
UNASSIGNED: The double-bending technique may be the best procedure for preventing the backing out of the K-wire and postoperative complications, such as range of motion restriction, for treating olecranon fractures that are treatable by TBW.
UNASSIGNED: Therapeutic IV.

UNASSIGNED: Elastic stable intramedullary nail (ESIN) is a commonly used method for treating diaphyseal fractures of the tibia, but its application in Distal Tibial Diaphyseal Metaphyseal Junction (DTDMJ) fractures has been a subject of controversy. This study aims to evaluate the clinical efficacy of the Elastic stable intramedullary nail-Kirschner wire (E-K) technique in treating pediatric DTDMJ fractures, providing better clinical decision-making for clinicians in diagnosing and treating such fractures.
UNASSIGNED: We conducted a retrospective analysis of patients aged 3-9 years who received treatment at our hospital from January 2019-January 2021 for distal tibial diaphyseal metaphyseal junction (DTDMJ) fractures. Based on their surgical procedures, they were categorized into the Elastic Stable Intramedullary Nail-Kirschner wire group (E-K) and the ESIN group. Demographic data, surgical duration, clinical outcomes, complications, and imaging data were recorded.
UNASSIGNED: The study included a total of 57 patients, with 24 cases in the E-K group and 33 cases in the ESIN group. There were 30 males and 27 females. The average age was (6.25 ± 1.59) years in the E-K group and (6.27 ± 1.48) years in the ESIN group. There were no significant differences between the two groups in terms of gender, age, weight, time from injury to surgery, follow-up time, side of injury, associated injuries, nail site infection, deep infection, and nail removal time (P > 0.05). Neither group experienced nonunion or refracture. The E-K group exhibited significantly lower coronal and sagittal plane angular values at the final follow-up compared to the ESIN group (P < 0.001). In the E-K group, the final follow-up coronal plane angle was 2.67 (1.09)°, while in the ESIN group, it was 6.55 (2.05)°. The final follow-up sagittal plane angle was 3.12 (1.54)° in the E-K group and 7.58 (1.48)° in the ESIN group. Both groups showed good alignment in the initial postoperative x-rays, with no statistically significant differences. However, during clinical healing, the ESIN group exhibited significant displacement, whereas the E-K group had minimal displacement, demonstrating a significant statistical difference (P < 0.001). There was a statistically significant difference in the AOFAS joint function assessment between the two groups (P = 0.027).
UNASSIGNED: The E-K technique is a viable option for treating DTDMJ fractures in pediatric patients, with well-established clinical efficacy. Its advantages include a straightforward surgical procedure, safety, and a low incidence of severe complications.

OBJECTIVE: To compare screw versus Kirschner wire fixation in the treatment of lateral humeral condyle fractures in children.
METHODS: A systematic search was conducted in PubMed, Embase, the Cochrane library, Web of Science, China National Knowledge Internet(CNKI), Wanfang Datebase from in ception to February 2022. Studies comparing screws and Kirschner wire fixation in the treatment of lateral humeral condyle fractures in children were included. Outcome measures included and excluded by a set of inclusion and exclusion criteria and evaluated for their quality, their excellent and good rate of fracture healing, malunion, delayed union or nonunion, infection, limitation of elbow flexion or extension(>10°) were extracted and analyzed using software Rev Man 5.3.
RESULTS: A total of 9 retrospective studies involving 647 patients were included, with 255 patients in the screw fixation group(including screw combined with Kirschner wire) and 392 patients in the Kirschner wire fixation group. Meta analysis showed the following:infection rate in the screw group was significantly lower than that in the Kirschner wire group[OR=0.22, 95%CI(0.09, 0.56), P=0.001]. There were no significant differences between the 2 groups in excellent and good rate of fracture healing, malunion rate(P>0.05). Subgroup analysis showed that infection rate in the screw-only group was significantly lower than that in the Kirschner wire group[OR=0.18, 95%CI(0.05, 0.65), P=0.009].
CONCLUSIONS: For lateral humeral condyle fractures, Screw fixation alone had a lower infection rate than kirschner wire fixation and screw combined with Kirschner wire fixation. There were no significant differences in the excellent and good rate of fracture healing, malunion. In terms of postoperative efficacy and safety of internal fixation, orthopaedic surgeons are more likely to recommend screws for fixation of lateral humeral condyle fractures in children.

UNASSIGNED: To compare the effects of allogeneic tendon coracoclavicular ligament reconstruction combined with Kirschner wire fixation and clavicular hook plate fixation on early postoperative pain, postoperative shoulder joint function score and shoulder joint mobility in patients with acromioclavicular joint dislocation.
UNASSIGNED: From January 2020 to January 2023, 43 patients with acromioclavicular joint dislocation admitted to Xi \'an Honghui Hospital were included. Among them, 24 patients were treated with the clavicular hook plate technique (Hook Plate,HP) group, and 19 patients were treated with allogeneic tendon coracoclavicular ligament reconstruction combined with the Kirschner wire technique (Allogeneic Tendon, AT) group. The Constant-Murley score of shoulder joint function 6 months after operation, postoperative shoulder joint activity, preoperative and postoperative pain, operation time, intraoperative blood loss and complications were compared between the two groups.
UNASSIGNED: All 43 patients were followed up for an average of 9.7 (9-12) months. The intraoperative blood loss in the allogeneic tendon group was less than in the hook plate group. The Constant-Murley shoulder function score was higher than that in the hook plate group 6 months after the operation. The abduction and lifting activity was greater than that in the hook plate group. The visual analogue scale scores at 3 days and 14 days after operation were lower than those in the hook plate group. The difference was statistically significant (p < 0.001). There was 1 case (5.3%) of exudation around the Kirschner needle track in the allogeneic tendon reconstruction group, and 5 cases (20.8%) of complications in the hook plate group, including 1 case of internal fixation stimulation, 2 cases of acromion impingement syndrome, 1 case of acromioclavicular joint osteoarthritis, and 1 case of shoulder joint stiffness. The complication rate of the allogeneic tendon group was lower than that of the hook plate group.
UNASSIGNED: The clinical efficacy of allogeneic tendon coracoclavicular ligament reconstruction combined with Kirschner wire fixation in treating acromioclavicular joint dislocation (Rockwood type III-V) is better than hook plate internal fixation. The patients have less early postoperative pain and better recovery of shoulder joint function and shoulder joint mobility.

UNASSIGNED: We aimed to report radiological and clinical features of single bone intramedullary fixation of the radius in pediatric both bone forearm fractures using straight stainless steel Kirschner (K) wire.
UNASSIGNED: Fifty-eight children (42 boys and 16 girls) referred to our hospital with both bone diaphyseal forearm fractures were operated on by using the single bone rigid K-wire intramedullary fixation and mini-open technique. The mean follow-up time was 8.9 months (6-12).
UNASSIGNED: The mean age of the patients was 7.4 years (4-12). More than 2/3 of the fractures were in the right hand. Around 63% of the fractures were in the middle third, 28% in the distal third, and 9% in the proximal third. Moreover, 12% were open type I Gustilo-Anderson fractures. The mean time from injury to surgery was two days (1-4), and the mean length of hospital stay was 2.8 days (2-5). The mean duration of surgery was 24.7 minutes (18-38), and the mean follow-up time was 8.9 months (6-12). All fractures united within 4-16 weeks (mean: 7.62). The cast and implant were removed simultaneously as the radiographic fracture union. There was no serious complication. Superficial infection of the pin track and loosening of the pin occurred in three cases (5%), all controlled by antibiotics and timely removal of the pins. Mild restriction of elbow extension (less than 20 degrees) was observed in three cases, which returned to normal at the last follow-up. Limitation of dorsiflexion of the wrist by more than 20° occurred in two patients (35° and 45°), which reverted to 25° and 25°, respectively, at the last follow-up.
UNASSIGNED: In both bone forearm fractures in children, open reduction and internal fixation of only the radius with a stainless steel straight Kirschner wire could be a promising method with good results. This retrograde technique of intramedullary fixation is a simple and cost-effective method with minimal complications and acceptable outcomes in children aged 4-12 years.

OBJECTIVE: To explore clinical effect of precast curvature internal fixation with Kirschner needle in treating forearm fracture in children.
METHODS: From October 2019 to December 2022,32 children with forearm fractures were treated with precast curvature internal fixation with Kirkler\'s needles,including 25 males and 7 females,aged from 3 to 15 years old with an average of (8.0±0.5) years old,18 patients on the left side and 14 on the right side,24 patients with double fractures of radial and ulna,3 patients with Monteggia fractures,and 4 patients with Galeazzi fractures,and 1 patient with radial neck fracture of crooked cap. Operation time,intraoperative blood loss,C-arm fluoroscopy,fracture healing time and complications were recorded,and disabilities of arm,shoulder and hand (DASH) scale and Grace-Eversman forearm double fracture evaluation system were used to evaluate clinical efficacy of precast curvature internal fixation with Kirschner\'s needle for forearm fracture in children.
RESULTS: All 32 patients were followed up for 2 to 12 months with an average of (7.16±2.51) months. Intraoperative blood loss was (20.68±5.50) ml,C-arm fluoroscopy was(5.80±2.50),and operation time was (24.34±5.10) min,fracture healing time was (8.82±1.62) weeks. Two patients occurred complications,including postoperative rupture of extensor pollicis longus tendon in 1 patient and obvious displacement of fracture caused by rotation of prefabricated curvature Kirschler needle on bone marrow cavity in 1 patient. DASH scores ranged from 0 to 16 scores with an average of (8.32±1.50) scores. According to Grace-Eversman double fracture evaluation system,28 patients got excellent result,2 good and 2 fair.
CONCLUSIONS: The treatment of forearm fracture with Kirschner\'s needle prefabricated curvature internal fixation has advantages of less trauma,less bleeding,good reduction,stable fixation,fast fracture healing and good functional recovery.

UNASSIGNED: To analyze the effectiveness comparison of external fixator combined with Kirschner wire fixation and Kirschner wire fixation in the treatment of cubitus varus deformity in children.
UNASSIGNED: A retrospective case-control study was conducted to collect 36 children of postoperative supracondylar humerus fracture complicating cubitus varus deformity between January 2018 and July 2022. Among them, 17 cases were treated with distal humeral wedge osteotomy external fixation combined with Kirschner wire fixation (observation group), and 19 cases were treated with distal humeral wedge osteotomy and Kirschner wire fixation (control group). The baseline data including age, gender, deformity side, time from fracture to operation, carrying angle of the healthy side and preoperative carrying angle of the affected side, elbow flexion and extension range of motion, and lateral condylar prominence index (LCPI) showed no significant difference between the two groups ( P>0.05). The operation time, hospitalization cost, healing time of osteotomy, postoperative complications, and the carrying angle, LCPI, and elbow flexion and extention range of motion were recorded and compared between the two groups. The elbow function was assessed by Oppenheim score at 3 months after operation and at last follow-up.
UNASSIGNED: The children in both groups were followed up 13-48 months, with an average of 26.7 months. There was 1 case of needle tract infection in the observation group and 2 cases in the control group, and no nerve injury occurred, the difference in the incidence of complication (5.88% vs 10.53%) between the two groups was not significant ( χ 2=0.502, P=0.593). There was no significant difference in the operation time and fracture healing time between the two groups ( P>0.05); the hospitalization cost of the observation group was significantly higher than that of the control group ( P<0.05). The Oppenheim score of the observation group was significantly better than that of the control group at 3 months after operation ( P<0.05), but there was no significant difference in the Oppenheim score between the two groups at last follow-up ( P>0.05). At last follow-up, the carrying angle of affected side significantly improved in both groups when compared with preoperative ones ( P<0.05); the differences of the pre- and post-operative carrying angle of affected side and elbow flexion and extension range of motion showed no significant differences between the two groups ( P>0.05), but the difference in pre- and post-operative LCPI of the observation group was significantly better than that of the control group ( P<0.05).
UNASSIGNED: External fixator combined with Kirschner wire fixation and Kirschner wire fixation both can achieve satisfactory correction of cubitus varus deformity in children, and the former can achieve better short-term functional recovery of elbow joint and reduce the incidence of humeral lateral condyle protrusion.

OBJECTIVE: To compare the clinical effects of intramedullary elastic reduction of the \"de-sharpened Kirschner wire and traditional three-dimensional manipulation in the treatment of Gartland type III posterolateral supracondylar fracture of the humerus in children.
METHODS: A retrospective cohort analysis was made on 106 cases of Gartland type III posterolateral supracondylar fracture of the humerus treated in the Department of Orthopaedics of a Children\'s Hospital from March 2020 to March 2022. According to different surgical technology, the patients were divided into two groups: intramedullary elastic reduction of the de-sharpened Kirschner wire group (experimental group, n = 50) and traditional three-dimensional manipulation group (control group, n = 56). The surgical operating time, intraoperative fluoroscopy times, postoperative Baumann angle changes, postoperative elbow function Flynn score, and complications were collected and compared between the two groups.
RESULTS: All the enrolled cases underwent surgery successfully and were followed-up at least 6 months. The surgical operating time of the experimental group was 32.88 ± 3.69 min and that of the control group was 45.56 ± 10.13 min, and the difference was statistically significant (P < 0.05). The intraoperative fluoroscopy times were 20.62 ± 5.41 times in the experimental group and 32.48 ± 8.20 times in the control group (P < 0.05). The change of Baumann angle in the experimental group after operation was 2.3 ± 1.3 and that in the control group was 6.0 ± 2.1 (P < 0.5). Elbow joint Flynn scoring standard to evaluate the curative effect: the excellent and good rate was 98.00% (49/50) in the experimental group and 92.86% (52/56) in the control group (P > 0.5). There were no complications such as osteomyelitis, compartment syndrome, iatrogenic vascular and nerve injury, and myositis ossificans in either group.
CONCLUSIONS: Good functional outcome can be obtained with both intramedullary elastic reduction of the de-sharpened Kirschner wire and traditional three-dimensional manipulation for Gartland type III posterolateral displaced supracondylar fracture of the humerus in children; however, the former does not need repeated manipulation, and the operation time is shorter, the number of intraoperative fluoroscopy is less, and the recovery of the Baumann angle is better.

BACKGROUND: There are clear standards for when to operate on both distal epiphyseal and diaphyseal forearm fractures in children. However, paediatric surgeons are often faced with fractures in the transition zone between metaphysis and diaphysis. This aim of the study is to compare different treatment approaches for diametaphyseal forearm fractures, to classify different types of these fractures, and to define further assessment parameters and treatment recommendations.
METHODS: This retrospective study included all patients with diametaphyseal radial fractures who were seen at a paediatric surgery clinic between 01.01.2010 and 31.12.2013. Patients were treated either non-surgically (C) or surgically using bicortical Kirschner wire (BC-KW), intramedullary K-wire (IM-KW), elastic stable intramedullary nailing (ESIN), or combined bicortical and intramedullary K-wire (BCIM-KW).
RESULTS: During the study period, 547 patients presented with forearm fractures of which 88 patients (16%) had a fracture in the diametaphyseal region. The majority of diametaphyseal fractures were greenstick fractures (54.4%) followed by transverse fractures (44.3%). Distal fractures were predominantly treated with bicortical K-wiring (BC-KW, 40.5%) or non-surgically (C, 26.2%). Proximal fractures were treated by ESIN osteosynthesis (50%), followed by IM-KW (30%). Intermediate fractures were just as likely to be treated with one out of the 5 above-mentioned techniques. The ulna was involved in 64 of 88 cases. Depending on the type of fracture, it was treated either by ESIN osteosynthesis or non-surgically. No superior operative technique was identified.
CONCLUSIONS: The description of diametaphyseal fractures as a separate entity is important, because the therapy of these fractures is heterogeneous and challenging. A classification into proximal, intermediate, and distal may be useful in clinical decision-making. Despite the retrospective nature of this study, our data suggest that the use of a K-wire or combined technique BCIM-KW-technique, whenever technically feasible, achieves better radiological results without secondary dislocation. Further prospective studies are needed to provide better guidance to trauma surgeons.
