[Impact of buried versus exposed flexible intramedullary nails osteosynthesis on pediatric forearm fractures]. / Impacto de los clavos intramedulares flexibles frente a los expuestos para osteosíntesis en fracturas pediátricas de antebrazo.

In elastic stable intramedullary nailing (ESIN), there are different opinions among surgeons on whether to leave the nail buried in the same arm or to leave it exposed. OBJECTIVE: To determine the risk of re-fracture in patients with a nail buried directly into the amr or left exposed as a treatment for forearm fractures, and to investigate postoperative complications. PATIENTS AND METHOD: The study included 113 pediatric patients with a forearm fracture of both diaphyses. Two groups were formed according to whether the nail was buried (Group B, n: 53) in the same arm or left exposed (Group E, n: 60). Data on the number of open reductions, the time to nail removal, the anesthesia type used for its removal, the number of re-fractures, skin infection, and nail entry site irritation were analyzed. RESULTS: The mean union times between the groups were not significantly different (P = 0.371). The mean time of nail removal in group B (16.02 ± 1.29 weeks) was significantly longer than that of group E (6.65 ± 0.95 weeks) (P < 0.001). Open reduction rates were similar between groups (P = 0.401). The general anesthesia rate for nail removal in group B (77.4%) was significantly higher than group E (11.7%) (P < 0.001). The re-fracture rate was higher in patients who underwent open reduction in both groups (P < 0.001). CONCLUSION: The results of this study demonstrated that, despite the increased infection rate, leaving the nail exposed did not increase the re-fracture rate, which was associated with open reduction.

Reverse Essex-Lopresti and Other Forms of Longitudinal Forearm Instability.

SUMMARY: Longitudinal forearm instability is a consequence of interosseous ligament complex disruption. Radiographic identifiers should alert the surgeon to the disrupted structures. Understanding the injury pattern can simplify the treatment process. The clinical presentation will vary based on the involved interosseous ligament components. The surgeon should aim to restore the anatomic radioulnar relationship and then address the remaining pathology as needed. The central band is the foundational structure that maintains this relationship and should be addressed in each injury pattern when disrupted. In this study, we describe rare forms of longitudinal forearm instability.

[Central band reconstruction in Essex-Lopresti lesions]. / Rekonstruktion des Zentralen Bandes bei Essex-Lopresti-Verletzung.

OBJECTIVE: Restoration of longitudinal forearm stability by reconstruction of the central band (CB) of the interosseous membrane (IOM) of the forearm. INDICATIONS: Acute and chronic Essex-Lopresti lesions (EL) with longitudinal forearm instability. CONTRAINDICATIONS: Absolute: acute/subacute infection. Relative: severe complex regional pain syndrome (CRPS), bony deformity/bone loss, pronounced osteoarthritis of the elbow and wrist. SURGICAL TECHNIQUE: Ulnar approach with exposure of the ulna approximately 6 cm proximal to the ulnar styloid. Creation of a 3.5 mm drill hole from ulnar-distal to radial-proximal. A Fiberloop (Fa. Arthrex, Naples, FL, USA) is fixed to one end of the LARS (Ligament Advanced Reconstruction System, Fa. Corin Group, Cirencester, UK) in a whipstitch technique, is shuttled through the drill hole from radial to ulnar and fixed over a BicepsButton (Fa. Arthrex, Naples, FL, USA). Exposure of the radius through a modified Henry approach. A 3.5 mm drill hole is made from radial-proximal to ulnar-distal approximately 12 cm proximal to the radial styloid. The graft is shuttled from the ulnar to the radial incision directly on the palmar surface of the IOM and shortened to the required length. Another Fiberloop is used to perform a whipstitch on the free end of the LARS. The final fixation of the CB reconstruction is achieved by shuttling the Fiberloop sutures through the radial drill hole with fixation over a BicepsButton. POSTOPERATIVE MANAGEMENT: Short-term immobilization in a long arm cast with subsequent early functional treatment. RESULTS: Mediocre to poor clinical results are reported in the literature for the treatment of chronic EL. Future research will tell whether the advanced surgical techniques with CB reconstruction will lead to better clinical outcomes.

Single-staged revascularization and reconstruction after crush injury of the wrist and distal forearm: A protocolized approach.

BACKGROUND: Amputation of the wrist or distal forearm after high-energy trauma due to a crushing mechanism is associated with complex tissue defects, making repair, and reconstruction challenging. Given the difficulty of this type of salvage, patients unfortunately experience a high revision amputation rate. However, a higher quality of life has been reported in patients with successful reconstructions. Herein, we described a protocolized approach for revascularization and reconstruction for functional hand salvage after traumatic amputation from a crushing mechanism using an anterolateral thigh flap (ALT). METHODS: A retrospective review was performed between October 2016 and October 2023 for all patients who underwent single-stage emergent debridement, revascularization, and soft tissue coverage using the ALT after amputation at the level of the wrist or distal forearm secondary to high-energy crush injury. Charts were reviewed for the preoperative Mangled Extremity Salvage Score, intraoperative details including what structures were injured and the reconstructive method performed, and postoperative data such as follow-up duration, outcomes, and complications. RESULTS: Eleven patients met the inclusion criteria with an average age of 35.5 (21-49) years old. The average size of the skin soft tissue defects was 17.3 × 8 cm (range, length: 13-25 cm, width: 6-13 cm), and all cases had associated injury to the underlying bone, nerves, and blood vessels. The average size of the ALT flap used for reconstruction was 19.2 × 9.8 cm (range, length: 14-27 cm, width: 7-15 cm). All patients had survival of the replanted limb. One patient experienced partial flap necrosis that required secondary debridement and skin graft. Nine patients healed without requiring any additional debridement procedures. Patient follow-up averaged 24.6 (12-38) months. All patients achieved satisfactory functional recovery with Grade II to III of Chen's criteria. CONCLUSIONS: For patients with traumatic crush amputation to the wrist with surrounding soft tissue injury, thorough debridement, revascularization, and reconstruction of amputated limbs can be performed in a single stage using the ALT. A protocolized approach from two institutions is presented, demonstrating improved survival and reduced complications of the traumatized limb with improved long-term patient outcomes.

Is casting of displaced paediatric distal forearm fractures non-inferior to reduction under general anaesthesia? Study protocol for a pragmatic, randomized, controlled non-inferiority multicentre trial (the casting trial).

BACKGROUND: Treatment of displaced distal forearm fractures in children has traditionally been closed reduction and pin fixation, although they might heal and remodel without surgery with no functional impairment. No randomized controlled trials have been published comparing the patient-reported functional outcome following non-surgical or surgical treatment of displaced paediatric distal forearm fractures. METHODS: A multicentre non-inferiority randomized controlled trial. Children aged 4-10 years with a displaced distal forearm fracture will be offered inclusion, if the on-duty orthopaedic surgeon finds indication for surgical intervention. They will be allocated equally to non-surgical treatment (intervention) or surgical treatment of surgeon's choice (comparator). Follow-up will be 4 weeks and 3, 6, and 12 months. The primary outcome is the between-group difference in 12 months QuickDASH score. We will need a sample of 40 patients to show a 15-point difference with 80% power. DISCUSSION: The results of this trial may change our understanding of the healing potential of paediatric distal forearm fractures. If non-inferiority of non-surgical treatment is shown, the results may contribute to a reduction in future surgeries on children, who in turn can be treated without the risks and psychological burdens associated with surgery.

Paraumbilical Perforator Flap: A Reliable Option for Coverage of Soft Tissue Defects of Forearm and Hand.

Soft tissue injuries of the hand or forearm often results in exposure of tendon or bone which needs coverage with a suitable flap. This prospective observational study was carried out in National Institute of Traumatology and Orthopaedic Rehabilitation (NITOR), Dhaka, Bangladesh from February 2019 to January 2020, to evaluate the use of the pedicled paraumbilical perforator flaps as a reliable flap to cover such defects. Total 34 patients having soft tissue defects in the hand and forearm with exposed tendons, bones or implant were included in this study. All the defects were covered by paraumbilical perforator flap. The defects were caused by road traffic accident (n=22), machinery injury (n=10) and burn injury (n=2). Sixteen patients had defects involving the forearm, six over dorsum of hand, another two over first web space and the rest had defects over two or more areas of forearm, hand and wrist. Lateral extent of flaps was upto anterior axillary line in 41.18% cases and upto mid-axillary line in 55.88% cases. Flap division and final inset was done in second stage after 3 weeks. Donor site closed primarily in all cases, except in two cases where it was covered by skin graft. All the flaps survived with no incidence of flap necrosis, dehiscence or infection after first stage. However, after the division of the flap, two patients developed marginal necrosis of the proximal margin which healed spontaneously by conservative treatment. The mean flap surface area utilized was 108 cm2. Donor area healed well without any major complications. Three patients developing scar hypertrophy were treated with intra-lesional triamcinolone injections. The paraumbilical perforator flap is a reliable option to cover soft tissue defects of hand and forearm due to easier planning and harvesting of the flap, adequate skin paddle and minimum donor site morbidity.

The midterm psychological effect of cast removal procedures in children.

OBJECTIVES: This study aimed to compare the course of anxiety change in children who used headphones during cast removal with controls in midterm follow-up. PATIENTS AND METHODS: Sixty-six patients who underwent forearm fracture treatment with closed reduction and long arm casting between June 2021 and March 2023 were retrospectively reviewed. Patients were divided into two groups based on the use of headphones (n=27; 21 males, 6 females; mean age: 8.0±1.8 years; range, 6 to 12 years) or not (n=39; 27 males, 12 females; mean age: 8.9±1.8 years; range, 6 to 12 years) during cast removal with an oscillating saw. Primary outcome measures included preprocedure, postprocedure, and six-month anxiety assessments with the State-Trait Anxiety Inventory. RESULTS: There was an acute increase in the mean state anxiety scores after the procedure, which returned to below baseline at the six-month follow-up in the headphone (31.4±8.3, 33.3±8.7, and 25.1±4.1, respectively) and control groups (34.9±11.1, 37.4±9.5, and 27.3±5.3, respectively). The mean trait anxiety scores before the procedure, after the procedure, and at six months remained similar in the headphone (33.6±3.0, 34.6±3.2, and 32.4±2.8; p>0.05) and control groups (34.1±2.7, 33.7±3.0, and 33.7±3.0, p>0.05). CONCLUSION: This study suggests that the acute anxiety during cast removal did not create anxiety sequelae in the sixth month regardless of headphone use.

Buried or exposed Kirschner wire for the management of hand and forearm fractures: A systematic review, meta-analysis, and meta-regression.

BACKGROUND: The recommendation on whether to bury or expose the Kirschner wire (K-wire) for the management of fractures has still been controversial with inconsistent results in the published studies due to the potential issue associated with exposed K-wire is the heightened risk of infection, as it comes into direct contact with the external environment and air. This study aims to summarize the specific outcomes between buried and exposed K-wire for the management of hand and forearm fractures. METHODS: We conducted relevant literature searches on Europe PMC, Medline, Scopus, and Cochrane Library databases using specific keywords. This investigation focuses on individuals of any age diagnosed with hand or forearm fractures who underwent surgery involving Kirschner wire (K-wire) fixation. It examines the comparison between buried and exposed K-wire fixation, emphasizing primary outcome pin infection, along with secondary outcomes such as early pin removal, days to pin removal, and surgical duration. The study includes observational studies (cohort/case-control) or randomized clinical trials (RCTs). The results of continuous variables were pooled into the standardized mean difference (SMD), while dichotomous variables were pooled into odds ratio (OR) along with 95% confidence intervals using random-effect models. The quality of included studies was assessed with Cochrane Collaborations, Risk of Bias version 2 (RoB v2). RESULTS: A total of 11 studies were included. Our pooled analysis revealed that buried K-wire was associated with a lower risk of pin site infection [RR 0.49 (95% CI 0.36-0.67), p < 0.00001, I2 = 0%] and 33.85 days longer duration until pin removal [MD 33.85 days (95% CI 18.68-49.02), p < 0.0001, I2 = 99%] when compared with exposed K-wire. However, the duration of surgery was 9.98 minutes significantly longer in the buried K-wire [MD 6.98 minutes (95% CI 2.19-11.76), p = 0.004, I2 = 42%] with no significant difference in the early pin removal rate [RR 0.73 (95% CI 0.36-1.45), p = 0.37, I2 = 0%]. Further regression analysis revealed that sample size, age, sex, and duration of follow-up did not affect those relationships. CONCLUSION: Buried K-wire may offer benefits in reducing the infection rate with a longer duration until pin removal. However, further RCTs with larger sample sizes are still needed to confirm the results of our study.

Cat bite injuries to the hand and forearm: the impact of antibiotic treatment on microbiological findings and clinical outcome.

INTRODUCTION: Patients and physicians often underestimate cat bite injuries. The deep and narrow wound seals quickly and provides an environment for the inoculated saliva and bacteria. Interestingly, the literature reports no bacterial growth in the microbiological workup of wound swaps in up to 43%. The time between bite injury and the first clinical presentation, the start of antibiotic treatment and surgical debridement might affect these findings. Therefore, the current project examines if (1) these factors impact the outcome of microbiological results following cat bite injuries and (2) the detection of bacterial growth leads to higher complication rates, longer hospital stays, longer total treatment time, or higher total treatment costs. MATERIALS AND METHODS: This single-center retrospective study analyzed data from 102 adult patients. All patients received antibiotic and surgical treatment following a cat bite injury. Microbiological samples were collected during surgery in all cases. The time from the bite incident to the first presentation, beginning of antibiotic administration, and surgical debridement was calculated. Demographic data, complication rate, length of hospital stay, total treatment time, and total treatment costs were recorded. (1) A generalized linear model was fitted using the microbiological outcome as the dependent variable. (2) Two groups (negative or positive microbiological results) were formed and statistically compared. RESULTS: The median age was 50 (SD 16), and 72% were female. (1) The time from the bite incident to the first clinical presentation, antibiotic administration, or surgical treatment was not associated with the outcome of the microbiological result. (2) No significant differences were observed between the two groups. CONCLUSIONS: Our data do not suggest that early antibiotic administration or delayed surgical treatment affects the outcome of the microbiological workup following cat bite injuries to the hand and forearm. The microbiological outcome did not affect the complication rate, treatment time, and total treatment costs.

Options for Restoring Finger Extension in Mangled Forearm Injuries.

Restoration of finger extension in mutilating hand injuries is crucial for restoring prehension and independent use of the hand. Patients often express desire to restore finger extension once finger flexion is achieved. However, the extensive forearm injury precludes use of any of conventional donors like the wrist or finger flexors for transfer to restore finger extension. Two patients with sequelae of mangled forearm injuries, underwent biceps and long head of triceps transfer to the finger extensors to improve opening up of the fingers. We discuss the treatment considerations while planning these transfers and provide the technical details, rehabilitation and outcome of these patients. Both the patients expressed dramatic improvement of their hand function and were satisfied with the outcome. Biceps and long head of triceps could serve as an effective second-line donor for restoration of finger extension when the conventional donors are not available. Level of Evidence: Level V (Therapeutic).

Evaluation of surgical or conservative treatment of forearm fracture in pediatric floating elbow injuries.

OBJECTIVE: Floating elbow, which refers to a humerus fracture in the supracondylar region and a forearm fracture, is a very unusual injury. The purpose of this study is to compare the clinical results of patients with "floating elbows" who underwent surgical therapy and who were given forearm immobilization with a splint as follow-up care. PATIENTS AND METHODS: Fifteen patients who had been diagnosed with floating elbow owing to trauma were scanned retrospectively and followed up for at least a year. Eight individuals who suffered from broken forearms underwent surgical repair. After initial treatment, a lengthy arm splint was used to immobilize seven patients' arms. The modified Flynn criteria were used to analyze the data, and comparisons were made between the groups. RESULTS: The median age and mean follow-up time for patients whose forearms were conservatively followed was 6.1 years and 13.8 months, respectively. The median age of the patients who underwent forearm surgery was 8.5 years, and the average follow-up was 14.2 months. Five of the seven patients whose forearms underwent conservative follow-up had outstanding clinical outcomes, while two had poor and moderate outcomes. Four individuals who got surgical treatment for their forearms had excellent and good clinical outcomes, while the other four had intermediate and poor outcomes. Between the two groups, there was no discernible difference (p = 0.60). CONCLUSIONS: In the pediatric population with floating elbow injuries, using a cast for forearm fractures may not necessarily result in worse outcomes compared to surgical management.

Return to Sport After Fasciotomy for Chronic Exertional Compartment Syndrome of the Forearm: A Systematic Review.

BACKGROUND: Forearm chronic exertional compartment syndrome (CECS) can represent considerable functional impairment in certain active populations, particularly motorcycle racers. Patients with forearm CECS frequently require fasciotomy to relieve symptoms and return to sport (RTS). PURPOSE: To evaluate the rate at which athletes RTS after fasciotomy for forearm CECS and to compare RTS outcomes between fasciotomy techniques. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: Adhering to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic review of the PubMed, Scopus, and Cochrane databases was performed from database inception to December 2022 to identify all published reports of forearm CECS managed with fasciotomy. Included studies were analyzed for demographic information, surgical approaches, rehabilitation parameters, RTS rates, time from surgery at which athletes resumed sport, complications, and recurrence. RESULTS: A total of 38 studies (15 level 4 case series, 23 case reports) accounting for 500 patients (831 forearms) who underwent open fasciotomy (112 patients), minimally invasive fasciotomy (166 patients), and endoscopically assisted fasciotomy (222 patients) satisfied inclusion criteria. Most patients (88.0%) were motorcycle racers. The overall RTS rate at any level (RTS-A) was 94.2% (97.3%, 92.2%, and 98.5% for the open fasciotomy, minimally invasive fasciotomy, and endoscopically assisted fasciotomy groups, respectively; P = .010), and the overall RTS at preinjury level or higher was 86.8% (95.9%, 85.6%, and 95.2% for the open fasciotomy, minimally invasive fasciotomy, and endoscopically assisted fasciotomy groups, respectively; P = .132). There was a significant difference in RTS-A between the minimally invasive fasciotomy and endoscopically assisted fasciotomy groups (P = .004). The overall RTS time was 5.1 ± 2.3 weeks, patient satisfaction was 85.1%, and the recurrence rate was 2.4%, and there were no significant differences between fasciotomy approach groups (P = .456, P = .886, and P = .487, respectively). CONCLUSION: Patients who underwent fasciotomy for forearm CECS had high rates of RTS, quick RTS time, high levels of satisfaction, and low rates of recurrence. Outcomes were largely similar between the 3 fasciotomy approaches.

Therapeutic approaches of diametaphyseal radius fractures in children.

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.

An age-matched comparative study on intramedullary nailing and plate fixation of both-bone diaphyseal forearm fracture in adolescents.

OBJECTIVE: This study aimed to compare radiological and functional outcomes and complication rates between intramedullary nailing (IMN) and plate fixation for diaphyseal forearm fractures in adolescents via an age-matched analysis. METHODS: Data were collected from medical records at 11 hospitals from 2009 to 2019, and the age-matched study was conducted between IMN and plate fixation. Functional outcomes, radiographic outcomes, and postoperative complication rates were compared. RESULTS: The IMN group (Group N) and plate fixation group (Group P) each comprised 26 patients after age matching. The mean age after matching was 13.42 years old. Bone maturities at the wrist of the radius and ulna were not significantly different between the two groups (p = 0.764 and p = 1). At the last follow-up period, functional outcomes using the Price criteria were over 90% in both groups, and the rotational range of motion was comparable to that of the healthy side. Over 70% of cases in Group N were performed by closed reduction, and operation time was half that of Group P. Postoperative neurological symptoms and refractures were more common in Group P than in Group N, although not statistically significantly so. CONCLUSIONS: Treatment outcomes for age-matched adolescent diaphyseal forearm fractures were excellent with IMN, as well as with plate fixation in many cases despite fewer complications, better cosmesis, and shorter operative times with IMN. IMN for diaphyseal forearm fractures is a useful treatment option even in adolescents although the indications for the best procedure to perform should be considered depending on individual patient needs. LEVEL OF EVIDENCE IV: Multicenter retrospective study.

Refracture Following Operative Treatment of Pediatric Both Bone Forearm Fractures.

INTRODUCTION: Both bone forearm fractures are common injuries in children. Most can be treated with reduction and casting. Those that fail nonoperative management can be treated with a plate or intramedullary fixation; however, refracture remains a problem. The goal of this study is to evaluate the refracture rate in both bone forearm fractures based on the mode of fixation. METHODS: Institutional board review approval was obtained. A retrospective chart review from 2010 to 2021 at a single tertiary care institution was conducted for all operative patients <18 years who sustained a both bone forearm fracture. Groups were stratified based on initial operative fixation type: both bones fixated using nails, 1 bone fixated with a nail; both bones plated, and 1 bone plated. Further review was conducted to identify refractures following initial operative treatment. Statistical analyses were conducted using the χ 2 test of independence and Fisher's exact test. RESULTS: In all, 402 operatively treated both bone forearm fracture patients were identified. Two hundred fifty-six of these patients underwent intramedullary fixation (average age 10.3y/o), while 146 patients received plate fixation (average age 13.8y/o). Fracture location was similar across the nailing and plating cohorts, most often occurring in the mid-shaft region. Patients aged ≤10 years refractured at a significantly higher rate than patients aged >10 years across all operative fixation cohorts (12.5% vs. 2.5%, P <0.001). Among the 256 patients who underwent intramedullary fixation, 61.3% had both bones treated (n=157/256), whereas 38.7% received single bone fixation (n=99/256). Of the 146 plate fixations, 84.4% had both bones fixed (n=123/146), and only 15.8% were treated with single bone fixation (n=23/146). In the intramedullary group, 15 patients sustained refractures, 11 of whom were treated with single bone fixation (11.1%, n=11/99) versus 4 with both both fixation (2.5%, n=4/157). Among the plating group, 7 patients sustained refractures, 6 with both bone fixation (4.9%, n=6/123) and 1 in single bone fixation (4.3%, n=1/23). Refractures were found to be significantly more prevalent among patients treated with single bone compared with both bone intramedullary nail fixation (11.1% vs. 2.5%, P =0.006). By fixated bone, single bone ulna fixations had a higher refracture rate compared with both bone fixations (12.1% vs. 3.6%, P =0.003). CONCLUSION: The overall refracture rate following operative treatment of both bone fractures is 5.5% and is similar between intramedullary and plate fixations. Overall, patients ≤10 years of age had a higher rate of refracture. Among single bone fixations, higher refracture was seen with intramedullary fixations, and when the radius was treated nonoperatively. Surgeons may be able to reduce the refracture rate by performing intramedullary fixation of both bones instead of only one bone. Effective postoperative counseling among younger patients may also decrease refracture rates.

Time to surgery and outcomes following open reduction and internal fixation of both-bone forearm fractures.

PURPOSE: To determine the effect of time to surgery on outcomes following open reduction and internal fixation (ORIF) of both-bone forearm fractures (BBFFs). METHODS: Ninety-nine patients who underwent ORIF of BBFFs in a single academic medical center over a 16-year time period were retrospectively reviewed. Demographic and clinical data including age, sex, current smoking status, time from injury to surgery (tsurg), presence of open injury, polytrauma status, and complications were obtained. Radiographs of the affected extremity were reviewed for fracture morphology, reduction quality, and time to union (or presence of nonunion). In addition to descriptive statistics, Chi-square and Wilcoxon-Mann-Whitney tests were used to compare categorical and interval, respectively, with a significance level of 0.05. RESULTS: A tsurg > 48 h was associated with increased rate of delayed unions (tsurg < 48 h: 25% vs tsurg > 48 h: 59%, p = 0.03), but not complications (tsurg < 48 h: 44% vs tsurg > 48 h: 47%, p = 0.79). Open BBFFs were not associated with increased rates of delayed unions (closed: 16% vs open: 19%, p = 0.77) or complications (closed: 42% vs open: 53%, p = 0.29). A trend toward increased time to union with tsurg > 48 h was also seen, but did not reach significance (tsurg < 48 h: 13.5 weeks vs tsurg > 48 h: 15.7 weeks, p = 0.11). CONCLUSION: A tsurg > 48 h is associated with an increased rate of delayed union, but not complications, after ORIF of BBFFs. LEVEL OF EVIDENCE: Therapeutic Level III (Retrospective Cohort).

Pediatric Forearm Malunions.

The aim of this article is to review the evaluation and management of pediatric forearm malunions. Acceptable parameters for nonoperative management of pediatric forearm fractures are reviewed, followed by clinical and imaging workups of malunions and decision-making points for treatment. The landscape of available technology for planning and execution of corrective osteotomy is discussed. Several cases of pediatric forearm malunion are presented, along with surgical and functional outcomes. Recommendations are given regarding the authors' preferred approach for management of pediatric forearm malunions.

Comparison of four surgical methods for pediatric forearm double diaphyseal fractures: a retrospective analysis.

OBJECTIVE: One of the most frequent fractures in children is a double forearm fracture. They make up 26% of children's long bone fractures in the upper extremities and their incidence has increased in recent years. In this study, pediatric patients with double forearm fractures were treated using plate screw, intramedullary K-wire (I-KW), intramedullary titanium elastic nails (TENs), and hybrid fixation (HF) to compare the radiographic and functional results. PATIENTS AND METHODS: The printed and digital medical records were retrospectively examined from our hospital's archives after receiving consent from the regional ethics committee. Legal guardians of the patients, who were under the age of 18, gave their informed consent. Based on the surgical procedure used, the patients were split into 4 groups. Double plating was the D-P group, hybrid fixation method was the HF group, intramedullary elastic titanium nail was the TEN group, and intramedullary K-wire was the I-KW group. The study comprised 78 patients in total, with 19 patients in the HF group, 21 patients in the TEN group, 20 patients in the I-KW group, and 18 patients in the D-P group. RESULTS: When the mean operating times of the four approaches were compared, a substantial difference was found. The D-P group's mean operating time (65.2±4.9 minutes) was noticeably longer than those of the other groups (p<0.001). The HF group's mean operating time was 55.93.4 min longer than that of the TENs and I-KW groups, which was statistically significant (p<0.001). In comparison to the other groups, the D-P group's mean intraoperative fluoroscopy time was considerably shorter (6±3 sec) (p<0.001). When compared to the D-P group, it was considerably higher in the HF group (12±2 sec) (p<0.001). In comparison to the TENs (20±4 sec) and I-KW groups (19±5 sec), it was significantly lower in the HF group (p<0.001). In comparison to the HF group, the D-P group's tourniquet use lasted much longer (p<0.001). The TENs and I-KW groups did not use a tourniquet because a mini-incision was made. The D-P group's mean blood loss (110±10 ml) was substantially larger than that of the other groups (p<0.001) in the mean blood loss data. In comparison to the TENs (40±5 ml) and I-KW (40±5 ml) groups, the mean blood loss in the HF group (90±10 ml) was considerably larger (p<0.001). All patients received an above-elbow postoperative cast. The HF group (2 weeks) and the D-P group (2 weeks) experienced significantly less postoperative immobility than the TENs and I-KW groups (4.4 weeks, p<0.001). CONCLUSIONS: The four fixation techniques used in the current study for juvenile diaphyseal double forearm fractures produced positive clinical and functional outcomes. The hybrid fixation technique was discovered to be comparable to the other techniques and even beneficial in some ways. So, a safe and efficient treatment option for juvenile diaphyseal double forearm fractures is hybrid fixation.

Complications and Revision Surgery of Forearm Fractures.

Nonunion or malunion of forearm fractures may result in restricted range of motion or persistent pain, leading to limitations in activities of daily living. Complications may also present in the form of ectopic bone growth or persistent infections. A systematic method to evaluate complications resulting from forearm fractures is helpful to both determine the cause for the failure and plan for adequate reconstruction.
