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. RESULTS: Surgery 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 investigate the clinical efficacy and safety of ultrasound-guided closed reduction and internal fixation using Kirschner wire for the treatment of olecranon fractures of the ulna in children. METHODS: Between January 2019 and January 2021, 13 children with olecranon fracture were treated with ultrasound-guided closed reduction and percutaneous Kirschner wire internal fixation, including 10 males and 3 females. The age ranged from 3 to 14 years old. Children with ulnar olecranon fractures were evaluated using the Gicquel scoring system. The clinical evaluation encompassed postoperative pain, functional status, and range of motion, with a maximum score of 15 points. The radiological assessment contributed an additional 4 points. A cumulative score of more than 18 scores was classified as excellent, more than 17 scores as good, more than16 scores as fair, and less than 16 scores as poor. Clinical assessment:A score of 14 indicates excellent performance, a score of 13 reflects good performance, a score of 12 denotes fair performance, and a score of less than 11 signifies poor performance. RESULTS: A total of 13 patients were followed up, with a duration ranging from 6 to 12 months. According to the Gicquel scoring criteria, the comprehensive evaluation of clinical and radiographic findings yielded 10 excellent and 3 good outcomes. Evaluation based solely on clinical findings resulted in 13 excellent outcomes. CONCLUSION Ultrasound-guided percutaneous cross Kirschner wire fixation for children's olecranon fracture has the advantages of less trauma, rapid recovery, less fluoroscopy, and good recovery of elbow function. The clinical effect is satisfactory.

OBJECTIVE: To investigate the effectiveness of sequential plate internal fixation in the correction of Madelung deformity after ulnar osteotomy and shortening. METHODS: The clinical data of 13 patients with Madelung deformity admitted between September 2015 and July 2021 were retrospectively analyzed. There were 5 males and 8 females with an average age of 18.3 years ranging from 17 to 23 years. The disease duration ranged from 12 to 24 months, with an average of 17 months. Three cases had a clear history of trauma. All patients had external radial deviation deformity and limited movement of the ulnar deviation, and the ulnar impact pain was significant during ulnar deviation movement; 9 patients had limited wrist joint supination movement, and the supination movement was normal. In the first stage, ulnar osteotomy and shortening combined with external fixator were used to correct wrist deformity in 13 patients. After operation, bone transfer was performed 6 times per day, with adjustments made every 4 hours, which was 1 mm per day. After the osteotomy was in place, the ulnar plate internal fixation was performed to reconstruct the ulnar stability in the second stage. The Cooney wrist joint score was used to assess the pain, function, range of motion, flexion and extension range of motion, and grip strength of the wrist joint before operation and before the removal of internal fixator. The subjective feeling and appearance satisfaction of patients were recorded. RESULTS: After the second-stage operation, all the 13 patients were followed up 10-22 months, with an average of 15 months. The deformity of wrist joint disappeared after operation, and the flexion, extension, and ulnar deviation were basically normal. There was no complication such as ulnar impingement sign, nonunion or infection. Wrist function, pain, and range of motion were significantly improved after operation, except for 1 patient who had no significant improvement in rotation and pain. The ulnar internal fixator was removed at 10-18 months after the second-stage operation. The scores of pain, function, range of motion, flexion and extension range of motion, and grip strength in the Cooney wrist score before removal of internal fixator significantly improved when compared with those before operation ( P<0.05). Subjective and appearance satisfaction of patients were excellent in 9 cases, good in 3 cases, and fair in 1 case. CONCLUSION Ulnar osteotomy and shortening with sequential plate internal fixation for correction of Madelung deformity, with mild postoperative pain, can effectively avoid bone nonunion, improve wrist joint function, and have significant effectiveness.

OBJECTIVE: To compare the clinical effect of three types of Kirschner wire tension band for olecranon fracture. METHODS: The clinical data of 64 patients with olecranon fracture treated by Kirschner wire tension band fixation from March 2016 to May 2020 were retrospectively analyzed. Among them, 19 patients were treated with intramedullary K-wires fixation(group A) including 8 males and 11 females with an average of (48.2±18.3) years old, 3 patients were typeⅠ, and 16 patients were typeⅡ according to Mayo classification;20 patients were treated with transcortical K-wires fixation (group B) including 13 males and 7 females with an average of (43.5±20.4) years old, 3 patients were typeⅠand 17 patients were typeⅡ according to Mayo classification;25 patients were treated with perforated Kirschner wire(group C) including 15 males and 10 females with an average of (55.2±17.5) years old, 4 patients were typeⅠand 21 patients were typeⅡ according to Mayo classification. The operative time, intraoperative blood loss, times of Intraoperative fluoroscopy, fracture healing time and complications of 3 groups were compared. At the final follow-up, elbow function was assessed using the Mayo Elbow Function Scale. RESULTS: There were differences in operative time, intraoperative fluoroscopy times, postoperative VAS and soft tissue irritation among the three groups(P<0.05). The operative time, intraoperative fluoroscopy times in group A and C was better than that in group B. The postoperative VAS score, skin irritability in group C was better than that of group B. The difference was statistically significant on Mayo elbow function score at the final follow-up among three groups(P<0.05), the scores of group A and C were higher than that of group B. CONCLUSION Compared with transcortical K-wires screw fixation, both intramedullary K-wires screw fixation and perforated Kirschner wire fixation, which can significantly reduce the occurrence of soft tissue irritation, reduce surgical complications and shorten the operation time.

PURPOSE: Olecranon fractures are particularly vulnerable to distraction and subsequent fracture dislocation due to the high tensile forces. Surgical treatment aims at reducing the fracture and restoring the anatomical joint surface condition, as well as neutralizing the strain inhibiting fracture healing. The XS nail® (Intercus GmbH, Bad Blankenberg, Germany), an intramedullary implant exerting compression across the entire fracture surface, unlike plates, leaves a minimal extra-cortical profile, and can be secured with threaded locking wires, thereby retaining the anatomical reduction without displacement or steps within the articular surface, which was often found in tension band wiring. After encouraging initial results, the long-term outcome was assessed. METHODS: This retrospective study evaluated the long-term outcome of patients surgically treated at our trauma center between January 2002 and December 2005 using the XS nail®. Patients over the age of 18 years eligible for the study must have undergone surgery for isolated, recent (less than 14 days) traumatic olecranon fractures, without concomitant injuries to the ipsilateral elbow and forearm. Further exclusion criteria were pseudarthrosis, re-fractures and osteotomy for distal humerus surgery, as well as polytraumatized patients unable to aid in their own recovery. Data were retrospectively gathered by standardised questionnaire and patient records, as well as surgery and anesthesiology reports. Data analysis was performed using Microsoft Office Excel® 2016. RESULTS: There were 32 patients, 13 males (mean age 49.0 years) and 19 females (mean age 68.9 years) with 11 Schatzkers type D, 7 each type A and C, 5 type B and 2 type E at an average of 55.2 months, all showing complete consolidation. Of them, 6 patients had a loss of range of motion with more than 10° in the sagittal plane, and only 1 patient exceeded 10° reduction of supination. Twenty-five patients reported being pain-free under all circumstances, and all but 2 patients (93.75%) had returned to their previous activity level. The average disabilities of the arm, shoulder and hand score was 21.15 (range 0-88.3), and the overall Mayo elbow performance index was 91.87, without complications, such as wound infection, neurovascular impairment or premature hardware removal. CONCLUSION Using the XS nail® system, all fracture types can be successfully treated and the rate of complications was lower than that treated by standard methods published in current literature. An excellent functional outcome, high range of motion as well as good retention of reduction without soft tissue irritation makes this a very suitable implant for fractures subject to tension.

OBJECTIVE: To investigate the clinical results of locking compression plate combined with autologous iliac bone graft in the treatment of aseptic ulnar nonunion. METHODS: From March 2009 to July 2017, 22 patients with aseptic ulnar diaphyseal nonunion with complete follow-up data were treated with surgery, including 12 males and 10 females, aged from 16 to 58 (39.7±9.9) years old and ranging in course of disease from 10 to 192 (39.4±55.7) months. There were 15 atrophic nonunions, 5 hypertrophic nonunions and 2 synovial pseudo-articular nonunions. After debridement of the nonunion, locking compression plate was used to fix the nonunion and autogenous iliac bone graft was given. Bone healing rate, surgical complications and clinical results were evaluated. RESULTS: All the patients were followed up, and the duration ranged from 13 to 42 months, with a mean of (22.5±8.2) months, and 1 patient did not heal. Visual analogue pain scores ranged from 0 to 3 (0.9±0.9). Pronation of forearm was 47 to 86 (69.0±14.7) degrees, supination was 35 to 85 (63.0±9.4) degrees, wrist flexion was 20 to 80 (51.0±10.2) degrees, wrist flexion was 32 to 88 (71.0±11.7) degrees, elbow flexion contracture was 0 to 25 (9.0±5.6) degrees, further flexion was 105 to 150 (134.0±13.9) degrees, and grip strength was 87% on the opposite side. According to the Anderson scoring system, 8 cases were excellent, 11 were satisfied, 2 were not satisfied, and 1 was failed. CONCLUSIONS LCP combined with autologous iliac bone graft can effectively treat aseptic ulna diaphyseal nonunion.

Dislocation of the elbow along with shaft fractures of both bones of the ipsilateral forearm is a rare injury though elbow dislocation or fracture of the forearm bones may occur separately. Such injuries need a concentric reduction of the dislocation and an anatomical fixation of forearm bones for optimal functional outcomes. We report a case of elbow dislocation with fracture of the lateral condyle of the humerus along with fractures of shafts of the radius and ulna in a 44-year-old female. Closed reduction of the elbow and operative stabilization of all fractures were done with good clinical, radiological and functional outcomes in 2 years follow-up period. A significant degree of force is needed to produce a combined dislocation of a joint and fracture of bones around that joint and these complex injuries may be missed if the clinician is not aware of the possibility of such injuries. The fact that the previously reported cases had a posterolateral dislocation while our case had a posteromedial dislocation and a fracture of the lateral humeral condyle as well makes it unique in its presentation and worth reporting. We have also included an up to date literature review on this topic.

Proximal ulna fractures account for 20% of all proximal forearm fractures. Many treatment options are available for such fractures, such as cast immobilisation, plate and screw fixation, tension band wiring and intramedullary screw fixation, depending on the fracture pattern. Due to the subcutaneous nature of the proximal forearm, it is vulnerable to open injuries over the dorsal aspect of the proximal ulna. This may in turn prove challenging, as it is critical to obtain adequate soft tissue coverage to reduce the risk of implant exposure and bony infections. We herein describe a patient with a Gustillo III-B open fracture of the proximal ulna, treated with minimally invasive intramedullary screw fixation using a 6.0-mm cannulated headless titanium compression screw (FusiFIX, Péronnas, France).

OBJECTIVETo analyze effects of fracture of processus styloideus ulnae on prognosis in the treatment of distal radial fracture of type C according to AO classification.

METHODSThis was a retrospective case-control study, and the information was got ten through case evaluation and follow-up, including sex, age, patient satisfaction, Gartland & Werley score and radiographic score. There were 76 patient treated with open reduction and plate fixation in People's Hospital Affiliated to Peking University from July 2006 to July 2011. All the patients were divided into two groups: no combination with fracture of processus styloideus ulnae (group A, 56 cases), combination with fracture of processus styloideus ulnae (group B, 20 cases). The patients in group A and B were treated with open reduction and internal fixation; however the fracture of processus styloideus ulnae was not fixed. The indexes such as clinical data, bone grafting, joint movement, Gartland & Werley score and radiographic score were compared between two groups.

RESULTSThe ulnaris pain of patients in group B was more obvious than that in group A. The local VAS, palmar and dorsal flexion degree of wrist joint, motion VAS, patients satisfaction score, radial and ulnar deviation degree, pronation and supination of forearm degree, Gartland & Werley score and radiographic score were separately 0.1 ± 0.1, (51.1 ± 1.9)°, (60.2 ± 1.9)°, 0.6 ± 0.1 (23.1 ± 0.9)°, (28.7 ± 1.3)° (81.5 ± 2.6)°, (68.2 ± 2.7)° 1.9 ± 0.3, 89.6 ± 12.3 in group A; and separately 0.3 ± 0.3, (51.4 ± 2.3)°, (66.6 ± 1.7)°, 0.5 ± 0.2, (24.5 ± 2.0)°, (26.9 ± 1.8)°, (80.3 ± 2.5)°, (70.3 ± 3.7)°, 1.2 ± 0.4, 92.5 ± 7.5 in group B; there were no statistical differences in above indexes between two groups.

CONCLUSIONWhether the distal radial fracture with a concomitant unrepaired ulnar styloid fracture or not exerts no influence on mainly outcomes including function, radiography and motion of the wrist.
