RESUMO
Purpose: The objective of this scoping review was to describe the extent and type of evidence of using guided growth to correct rotational deformities of long bones in children. Methods: This scoping review was conducted in accordance with the JBI methodology for scoping reviews. All published and unpublished studies investigating surgical methods using guided growth to perform gradual rotation of long bones were included. Results: Fourteen studies were included: one review, three clinical studies, and ten preclinical studies. In the three clinical studies, three different surgical methods were used on 21 children. Some degree of rotation was achieved in all but two children. Adverse effects reported included limb length discrepancy (LLD), knee stiffness and rebound of rotation after removal of tethers. Of the ten preclinical studies, two were ex vivo and eight were in vivo. Rotation was achieved in all preclinical studies. Adverse effects reported included implant extrusions, LLD, articular deformities, joint stiffness and rebound of rotation after removal of tethers. Two of the studies reported on histological changes. Conclusions: All studies conclude that guided growth is a potential treatment for rotational deformities of long bones. There is great variation in animal models and surgical methods used and in reported adverse effects. More research is needed to shed light on the best surgical guided growth method, its effectiveness as well as the involved risks and complications. Based on current evidence the procedure is still to be considered experimental. Level of evidence: 4.
RESUMO
Noninvasive techniques are gold standard to redress Severe Neuromuscular Foot Deformity (SNFD). However, simple talectomy may be considered to obtain a stable, plantigrade, pain-free foot. We present a 10-year follow-up accessing radiological correction rates, functional outcomes, complications, and patient satisfaction. This retrospective case series evaluated talectomies in 2012 to 2022. Simple talectomy was combined with Steinman pin fixation of calcaneus to tibia for approximately 6 weeks. Diagnoses primarily included arthrogryposis multiplex congenita and cerebral palsy. Indications were pain, wounds/pressure marks, severe rigidity, and residual/recurrent deformity. The primary outcome was radiological correction. Tibiotalar angle (TiTa) and tibiocalcaneal angle (TiCa) were measured on mediolateral projections. Secondary outcomes were functional scores of pain/deformity graded as good, fair or poor. Furthermore, validated patient-reported outcome measures, that is, EQ-5D-5L and the Scoliosis Research Society-30 Questionnaire (2 items) assessed health-related quality of life and patient satisfaction. Nineteen talectomies in 11 patients were analyzed. Mean follow-up was 62 months (range 9-112 months). Mean TiTa was 137° (95%CI 128;146). TiCa improved significantly: Mean difference -24° (95%CI -44;-5, p = .02). All feet became plantigrade and pain-free with no skin issues. Functional outcomes were graded as 9/19 good, 10/19 fair and 0/19 poor. Parents/primary caregivers were mainly satisfied. Perceived health was 54 (95%CI 34;75) out of 100 on a visual analogue scale, emphasizing complex medical conditions. In conclusion, simple talectomy is a suitable salvage procedure for SNFD.

CASE: A 15-year-old girl known with osteogenesis imperfecta presented with left femoral pain. She had been treated with multiple Fassier-Duval intramedullary nails, which were still in situ. Radiographic imaging demonstrated focal osteolysis and periosteal reaction at the telescopic junction of the rod in the distal femur. She underwent implant removal. Intraoperative sampling demonstrating acute sterile inflammation and presence of brownish colored particles consistent with metal debris and osteolysis. Explant analysis confirmed corrosion of the stainless-steel telescopic nail as the underlying cause. CONCLUSION: Osteolysis and periosteal reaction because of corrosion should be considered in conjunction with other more common causes of pain, such as fracture or infection, in patients treated with telescopic intramedullary nails.

BACKGROUND AND PURPOSE: Bilateral femoral distraction osteogenesis in patients with achondroplasia is insufficiently reported. We aimed to perform the first study that exclusively analyzed simultaneous bilateral femoral distraction osteogenesis with motorized intramedullary lengthening nails via an antegrade approach in patients with achondroplasia focused on reliability, accuracy, precision, and the evolving complications. PATIENTS AND METHODS: In this retrospective singlecenter study we analyzed patients with achondroplasia who underwent simultaneous bilateral femoral lengthening with antegrade intramedullary lengthening nails between October 2014 and April 2019. 15 patients (30 femoral segments) of median age 14 years (interquartile range [IQR] 12-15) were available for analysis. The median follow-up was 29 months (IQR 27-37) after nail implantation. RESULTS: The median distraction length per segment was 49 mm (IQR 47-51) with a median distraction index of 1.0 mm/day (IQR 0.9-1.0), and a median consolidation index of 20 days/cm (IQR 17-23). Reliability of the lengthening nails was 97% and their calculated accuracy and precision were 96% and 95%, respectively. The most common complication was temporary restriction of knee range of motion during distraction in 10 of 30 of the lengthened segments. 1 patient was treated with 2 unplanned additional surgeries due to premature consolidation. CONCLUSION: The method is reliable and accurate with few complications.

INTRODUCTION: The STRYKER ADAPT computer-assisted navigation system provides intraoperative feedback to the surgeon regarding implant placement of the Gamma3 nail. The usability of the ADAPT system has not been evaluated. The aim of the study was to investigate the perceived usability of the ADAPT system. MATERIALS AND METHODS: This was a descriptive study with prospectively collected data. ADAPT was introduced at Aarhus University Hospital in February 2021. Prior to introduction, surgeons at the department attended a general introduction to the system. ADAPT was introduced to the surgical nurses and was on display at the surgical ward at more than one occasion, where personal introduction to the system was possible. After introduction, it was mandatory to use ADAPT when using the Gamma3 nail to treat intertrochanteric femur fractures. After each procedure, primary and an eventual supervisor answered a questionnaire, which encompassed the System Usability Scale (SUS) questionnaire. The SUS is a ten-item questionnaire regarding the perceived usability of a system. SUS scores were translated to adjectives, describing user experience on a 7-point adjective scale (worst imaginable, awful, poor, ok, good, excellent, best imaginable). User acceptability, defined as "not acceptable", "marginal" or "acceptable", was also used to interpret the SUS scores. RESULTS: ADAPT was used in 50 procedures by 29 different surgeons, with varying skill-level. Median SUS-score after first-time use of ADAPT for all 29 surgeons was 43 (range: 5-60), which translated to "poor" or "not acceptable". For surgeons who performed ≥ 3 ADAPT-assisted procedures, there were no statistically significant difference in their first to latest SUS-score (median difference: 4.3, p = 0.5). In free text comments ADAPT was positively described as helpful in placement of K-wire and providing educational opportunities for inexperienced surgeons and negatively as inconsistent, slow, time consuming, and causing excessive fluoroscopy. CONCLUSIONS: Usability and acceptability of ADAPT was rated as "poor" or "not acceptable" by the majority of operating surgeons. ADAPT has not been used at our institution based on these findings. The System Usability Scale may be used in further research exploring usability and acceptability of novel computer-assisted navigation systems for orthopaedic surgery.

Psychomotor skill and decision-making efficiency in surgical wire navigation can be objectively evaluated by analysis of intraoperative fluoroscopic image sequences. Prior work suggests that such image-based behavior analysis of operating room (OR) performance can predict performer experience level (R2 = 0.62) and agree with expert opinion (the current standard) on the quality of a final implant construct (R2 = 0.59). However, it is unclear how objective image-based evaluation compares with expert assessments for entire technical OR performances. This study examines the relationships between three key variables: (1) objective image-based criteria, (2) expert opinions, and (3) performing surgeon experience level. A paired-comparison survey of seven experts, based upon eight OR fluoroscopic wire navigation image sequences, shows that the experts' preferences are best explained by objective metrics that reflect psychomotor and decision-making behaviors which are counter-productive to successful implant placement, like image count (R2 = 0.83) and behavior tally (R2 = 0.74). One such behavior, adjustments away from goal, uniquely correlated well with all three key variables: a fluoroscopic image-based analysis composite score (R2 = 0.40), expert consensus (R2 = 0.76), and performer experience (R2 = 0.41). These results confirm that experts view less efficient technical behavior as indicative of lesser technical proficiency. While expert assessments of technical skill were reliable and consistent, neither individual nor consensus expert opinion appears to correlate with performer experience (R2 = 0.11).

Introduction: The aim of the study was to assess the surgical case volume of residents before and after simulation-based training in hip fracture surgery provided on demand versus knee and shoulder arthroscopy provided on supply. Materials and Methods: A retrospective analysis of surgical case volume in hip fracture surgery and arthroscopic shoulder and knee procedures 90 days before and after simulation-based training of either procedure. Sixty-nine orthopedic residents voluntarily participating in either simulation-based training. Hip fracture surgery simulation was provided on supply, ie, whenever 1-2 residents applied for the course, while the arthroscopic simulation course was supplied twice yearly. Results: Thirty-four residents participated in hip fracture simulation on demand and 35 residents participated in arthroscopic simulation on supply. The surgical case volume of hip fracture osteosynthesis increased from median 2.5 (range: 0-21) to median 11.5 (1-17) from 90 days before to the 90 days after the simulation-based training on demand. The median difference was 6.5 procedures (p < 0.0003). On the contrary, the surgical case volume in shoulder and knee arthroscopy was low both before and after the simulation on supply, ie, median 2 (0-22) before and median 1 (0-31) after. The median difference was 0 (p = 0.21). Conclusions: Simulation on demand was associated with increased opportunities to perform in the clinical environment after the simulation-based training compared with simulation on supply. Simulation-based training should be aligned with the clinical rotation of the residents. Simulation on demand instead of supply on fixed dates may overcome this organizational issue of aligning training with the opportunity to perform.
RESUMO
Intertrochanteric femoral fractures are commonly treated with intramedullary nails (IMNs). A tip-apex distance (TAD) of more than 20-25 mm is associated with an increased risk of cut-out. The Stryker Adaptive Positioning System (ADAPT) is a computer-assisted navigation system designed to reduce TADs. We aim to assess if the ADAPT reduces the number of outliers with a TAD > 20 mm. All patients with intertrochanteric fractures treated with an IMN between 1 September 2020 and 12 March 2022 were included. Patients were included in three periods: a pre-ADAPT period (55 patients); an ADAPT period (50 patients), where it was compulsory to use the system; and a post-ADAPT period after the discontinuation of the system (59 patients). The TADs and lag screw protrusions beyond the lateral cortex were measured. The median TADs in the three periods were 17.0 mm (8-31 mm), 15.5 mm (9-30 mm), and 18.0 mm (11-32 mm), respectively. The absolute number of outliers with a TAD > 20 mm decreased from 15/55 patients in the pre-ADAPT period to 11/50 patients during the ADAPT period. This observation was not statistically significant, but this is likely due to the lack of power of the present study to show changes of this magnitude. However, our expectation that the ADAPT would diminish outliers markedly or close to zero outliers was not met, as we observed 11/50 = 22% outliers with a TAD > 20 mm when using computer-assisted surgery, i.e., ADAPT and Gamma3 for intertrochanteric fractures. Based on these findings, the use of the ADAPT was discontinued at our level 1 trauma center.
RESUMO
BACKGROUND AND PURPOSE: Temporary hemiepiphysiodesis by tension-band devices is commonly applied to correct angular limb deformities in children. We aimed to evaluate knee joint morphology after guided growth using these devices. PATIENTS AND METHODS: In a retrospective multicenter study we analyzed standardized anteroposterior long-leg radiographs of 222 limbs (285 implants) of patients treated by temporary hemiepiphysiodesis with either eight-Plates or FlexTacks for coronal angular deformities of the knee joint between 2013 and 2019. Femoral floor angle (FFA), femoral notch-intercondylar distance (FNID), and tibial roof angle (TRA) were measured pre- and postoperatively to assess the central knee joint morphology. Statistical exploratory analyses were performed using linear mixed models, t-tests, Wilcoxon signed-rank test, and Mann-Whitney U test. RESULTS: 217 FlexTacks (femur 106, tibia 111) in 104 children and 68 eight-Plates (femur 61, tibia 7) in 35 children were identified. Median time period under growth guidance was 11 months (range 4-42). No statistically significant change in the FFA was detected (eight-Plate: P = 0.2; FlexTack: P = 0.3). A statistically significant difference of the FNID was found in the eight-Plate group (P = 0.02), but not in the FlexTack group (P = 0.3). While TRA increased in both groups, a statistical significance was observed only in the FlexTack group (P < 0.01). CONCLUSION: We found minor but clinically irrelevant changes in knee morphology after the treatment.

Recent studies have shown that distal radius fractures (DRFs) in elderly patients can be treated nonoperatively with good functional results after 1 year. However, scientific evidence regarding longer follow-up to assess posttraumatic arthritis (PA), complications, and functional outcomes is scarce. This prospective case series aimed to evaluate these outcomes in a cohort of patients ≥ 65-year-old with nonoperatively treated DRFs after a minimum of 3 years. The primary outcome was PA. Secondary outcomes were complications, Quick Disabilities of the Arm, Shoulder and Hand Outcome Measure (QuickDASH), Patient-Rated Wrist/Hand Evaluation (PRWHE), pain, range of motion and grip strength. The full data of 32 patients with a mean follow-up of 3.3 years were available: 10/32 patients had radiological signs of PA, but only 2 of these patients reported pain. A total of 11/32 fractures healed in malunion (> 10° dorsal angulation). There was no significant difference in QuickDASH or PRWHE from 1 year to the latest follow-up after more than 3 years. This study thus adds to the literature stating that radiological signs, including PA and malunion, do not necessarily result in symptoms. Moreover, it underpins that nonoperative treatment of these patients results in good functional outcomes after 1 and 3 years.

Morel-Lavallée lesion (MLL) is a closed degloving injury caused by traumatic sheering of subcutaneous tissue from the underlying fascia. MLL can be classified as acute (less-than 3 months) or chronic (greater-than 3 months or if a capsule has formed). Acute lesions are treated with compression, percutaneous aspiration, sclerodesis, suction-curettage or open surgery depending on vitality of the overlying skin, if fractures are present next to the lesion or if infection has occurred. Chronic lesions are treated with sclerodesis, suction-curettage or open surgery. Drain and vacuum-assisted closure placement should be used post-operatively, as argued in this review.

For paediatric orthopaedic surgeons treating leg length discrepancy, knowledge of the available procedures and their options and limits is just as important as mastery of the very different surgical methods and implants, as well as the possible complications, in order to be able to advise and treat the children and adolescents and their parents comprehensively and in the best interests. Both the growth inhibiting procedures and the complex bone lengthening procedures require a great deal of experience to successfully guide patients and families through what is often a lengthy and sometimes complicated treatment process. Careful preoperative indications and planning, precise surgical techniques with suitable instruments and implants, and attentive postoperative check-ups are mandatory prerequisites for the desired therapeutic success.

(1) Background: Lower Limb deformities include many conditions where pain and physical limitations negatively impact the health-related quality of life (HRQL) of children. The ideal way to assess this impact is by using a Patient Reported Outcome Measure (PROM). Such a condition-specific PROM is under development, called LIMB-Q Kids. This study aimed to perform a translation and cultural adaption (TCA) of the LIMB-Q Kids for use in Danish-speaking children. (2) Methods: TCA guidelines established by the World Health Organization (WHO) and the Professional Society for Health Economics and Outcomes Research (ISPOR) were followed. This process consisted of two independent forward translations, a reconciliation meeting, a backward translation with an assessment, an expert meeting, cognitive interviews with patients, editing based on the interviews, and proofreading. (3) Results: The TCA process contributed to the Danish version of LIMB-Q Kids. The reconciliation meeting resulted in a reconciled Danish version. The revision of the backward translation led to 16 corrections, and after the expert panel meeting, 26 changes were made. Twelve cognitive interviews led to nine changes, which were validated by two further interviews. Proofreading led to no further comments. (4) Conclusions: The TCA process led to a linguistically validated and culturally adapted Danish version of LIMB-Q Kids. This version is being used in the international field test study.
RESUMO
BACKGROUND AND PURPOSE: For correction of leg-length discrepancy or angular deformity of the lower limb in skeletally immature patients temporary or permanent (hemi-)epiphysiodesis can be employed. These are reliable treatments with few complications. Recently, radiographic analysis of treatment-related alterations of the central knee anatomy gained interest among pediatric orthopedic surgeons. To date the comparison and adequate interpretation of potential changes of the central knee anatomy is limited due to the lack of defined standardized radiographic references. We aimed to establish new reference values of the central knee anatomy. PATIENTS AND METHODS: A retrospective analysis of calibrated longstanding anteroposterior radiographs of 254 skeletally immature patients with a chronological age ranging from 8 to 16 years was conducted. The following radiographic parameters were assessed: (1) femoral floor angle, (2) tibial roof angle, (3) width at femoral physis, and (4) femoral notch-intercondylar distance. RESULTS: All observed radiographic parameters were normally distributed with a mean age of 12.4 years (standard deviation [SD] 2, 95% confidence interval [CI] 12.2-12.6). Mean femoral floor angle was 142° (SD 6, CI 141.8-142.9), mean tibial roof angle was 144° (SD 5, CI 143.7-144.1), mean width at femoral physis was 73 mm (SD 6, CI 72.8-73.9), and mean femoral notch-intercondylar distance was 8 mm (SD 1, CI 7.5-7.7). The estimated intraclass correlation coefficient values were excellent for all measurements. CONCLUSION: This study provides new radiographic reference values of the central knee anatomy for children between 8 and 16 years and we suggest considering values within the range of 2 SD as the physiological range.

Leg length discrepancies (LLD) are frequently associated with coronal malalignment. Temporary hemiepiphysiodesis (HED) is a well-established procedure for the correction of limb malalignment in skeletally immature patients. For treatment of LLD > 2 cm, lengthening with intramedullary devices gains increasing popularity. However, no studies have investigated the combined application of HED and intramedullary lengthening in skeletally immature patients. This retrospective single-center study evaluated the clinical and radiological outcomes of femoral lengthening with an antegrade intramedullary lengthening nail combined with temporary HED performed in 25 patients (14 females) between 2014 and 2019. Temporary HED through the implantation of flexible staples of the distal femur and/or proximal tibia was either performed prior (n = 11), simultaneously (n = 10) or subsequently (n = 4) to femoral lengthening. The mean follow-up period was 3.7 years (±1.4). The median initial LLD was 39.0 mm (35.0-45.0). Twenty-one patients (84%) presented valgus and four (16%) showed varus malalignment. Leg length equalization was achieved in 13 of the skeletally mature patients (62%). The median LLD of the eight patients with residual LLD > 10 mm at skeletal maturity was 15.5 mm (12.8-21.8). Limb realignment was observed in nine of seventeen skeletally mature patients (53%) in the valgus group, and in one of four patients (25%) in the varus group. Combining antegrade femoral lengthening and temporary HED is a viable option to correct LLD and coronal limb malalignment in skeletally immature patients; however, achieving limb length equalization and realignment may be difficult in cases of severe LLD and angular deformity, in particular.
RESUMO
OBJECTIVE: Technical and non-technical skills are traditionally investigated separately in simulation-based surgical training (SBST). Recent literature has indicated an interrelation of these skills, but a clear relationship is yet to be established. This scoping review aimed to identify published literature on the use of both technical and non-technical learning objectives in SBST and investigate how the entities are related. Additionally, this scoping study reviewed the literature with the aim of mapping how publications on technical and non-technical skills within SBST have changed over time. DESIGN: We conducted a scoping review using the 5 step framework by Arksey and O'Malley and reported our results according to the PRISMA guidelines for scoping reviews. Four databases, PubMed, Web of Science, Embase and Cochrane Library, were systematically searched for empirical studies on SBST. Studies within surgical training addressing both technical and non-technical learning objectives and presenting primary data were included for further analysis. RESULTS: Our scoping review identified 3144 articles on SBST published between 1981 and 2021. During our analysis, an emphasis on technical skills training in published literature was identified. However, recent years have seen an immense increase of publications within either technical or non-technical skills. A similar trend is seen in publications addressing both technical and non-technical. In total, 106 publications addressed both technical and non-technical learning objectives and were included for further analysis. Only 45 of the included articles addressed the relationship between technical and non-technical skills. These articles mainly focused on the effect of non-technical skills on technical skills. CONCLUSIONS: Though literature on the relationship between technical and non-technical skills remains scarce, the included studies on technical skills and non-technical skills such as mental training suggest such a relationship exists. This implies that the separation of the skill sets is not necessarily beneficial for the outcome of SBST. A shift towards seeing technical and non-technical skills as intertwined may enhance learning outcomes from SBST.

BACKGROUND: Distal radius fractures (DRFs) in the elderly are common. Recently, the efficacy of operative treatment of displaced DRFs in patients above 65 years of age has been questioned and it has been suggested that non-operative treatment should be the gold standard. However, the complications and functional outcome of displaced vs. minimally and non-displaced DRFs in the elderly has not been evaluated yet. The aim of the present study was to compare non-operatively treated displaced DRFs vs. minimally and non-displaced DRFs in terms of complications, PROMs, grip strength and range of motion (ROM) after 2 weeks, 5 weeks, 6 months and 12 months. METHODS: We used a prospective cohort study that compared patients with displaced DRFs (n = 50), i.e., >10 degrees of dorsal angulation after two reduction attempts, with patients with minimally or non-displaced DRFs after reduction. Both cohorts received the same treatment of 5 weeks of dorsal plaster casting. Complications and functional outcomes (quick disabilities of the arm, shoulder and hand (QuickDASH), patient-rated wrist/hand evaluation (PRWHE), grip strength and EQ-5D scores) were assessed after 5 weeks, 6 months and 12 months post-injury. The protocol of the VOLCON RCT and present observational study has been published (PMC6599306; clinicaltrials.gov: NCT03716661). RESULTS: One year after 5 weeks of dorsal below-elbow casting of low-energy DRFs in patients ≥ 65 years old, we found a complication rate of 6.3% (3/48) in minimally or non-displaced DRFs and 16.6% (7/42) in displaced DRFs (p = 0.18). However, no statistically significant difference was observed in functional outcomes in terms of QuickDASH, pain, ROM, grip strength or EQ-5D scores. DISCUSSION: In patients above 65 years of age, non-operative treatment, i.e., closed reduction and dorsal casting for 5 weeks, yielded similar complication rates and functional outcomes after 1 year regardless of whether the initial fracture was non-displaced/minimally displaced or still displaced after closed reduction. While the initial closed reduction should still be attempted in order to restore the anatomy, failure to achieve the stipulated radiological criteria may not be as important as we thought in terms of complications and functional outcome.
RESUMO
BACKGROUND: Motorized lengthening nails are the treatment standard for bone lengthening of the lower limbs. However, bony changes namely osteolysis and periosteal hypertrophy have been described after certain type of magnetically driven lengthening nails. The aim of this study was to estimate the proportion rate of radiological bone abnormalities of Fitbone TAA femoral or tibial lengthening nails with a minimum follow-up time of 1 year. HYPOTHESIS: The bone surrounding the telescopic junction of Fitbone lengthening nails does not exhibit osteolysis or periosteal reactions. The bone surrounding the locking screws exhibits cortical hypertrophy. PATIENTS AND METHODS: Single-centre retrospective case series of patients treated with a Fitbone nails with a minimum follow-up of 1 year after implantation. Standard orthogonal radiographs were obtained postoperatively, weekly during the distraction phase, and then monthly for 6 months, and before removal of the equipment. We looked for bone abnormalities at the telescoping junction of the nail and at the locking screws before removal. RESULTS: In total, 101 patients (58 males, 43 females) with a mean age of 21 years (range: 11.8-53.5) had 128 (101 femoral and 27 tibial) limb lengthening nails implanted between 2010 and 2021. The mean follow-up period was 925 days (range: 371-3587). The mean lengthening was 4.7cm (range: 1.5-8.0). No bones exhibited focal osteolysis or periosteal reactions at the telescopic junction of the lengthening nail. Cortical hypertrophy at the locking screws was observed in significantly more Fitbone nails than previously reported, i.e., 101/128 (79%). DISCUSSION: Neither focal osteolysis, nor periosteal reactions were observed at the bone surrounding the telescopic junction of 128 Fitbone lengthening nails. Cortical hypertrophy around the single diaphyseal locking screw was observed in 101/128 (79%) of the cases. These absences of osteolytic changes after long term observation are reassuring for both surgeons and patients alike. LEVEL OF EVIDENCE: IV.

INTRODUCTION: Tibial shaft fractures are among the most common lower extremity fractures. Treatment of tibial shaft fractures with intramedullary nailing has become the treatment of choice in adults. However, commonly reported outcomes include knee pain, limitations in activities of daily living and reduction in quality of life (QOL). The literature lacks high-quality studies to document superiority of intramedullary nailing versus other surgical treatment methods. The present study aims to compare the 12-month Knee Injury and Osteoarthritis Outcome Score (KOOS) - sport and recreation activities (sport/rec) after standard intramedullary nailing with external ring fixation for adult patients with isolated tibial shaft fractures. METHODS: This study is a multicentre randomised, prospective clinical trial. A total of 67 patients will be included in the study, and the primary outcome will be the KOOS-sport/rec at 12 months after surgery. CONCLUSIONS: With KOOS-sport/rec as the primary outcome, the findings of the present study are expected to advance our understanding of knee pain, function and QOL, regardless of the treatment option and the outcome of the study. FUNDING: The project is partially funded by the Independent Research Found Denmark. CLINICALTRIALS: gov ID: NCT-03945669, version 1.1, 21 September 2022.

BACKGROUND: Primary aim: to compare complications of operative vs non-operative treatment of unstable distal radius fractures (DRF) fulfilling national clinical guidelines for operative treatment. Secondary aim: to compare the functional outcomes. MATERIALS AND METHODS: A single-centre randomized controlled trial of unstable DRF. 50 patients: volar locking plate, 2 weeks casting + 3 weeks orthosis. 50 patients: 5 weeks casting. PRIMARY OUTCOME: complications assessed after 2 and 5 weeks and 6 and 12 months. SECONDARY OUTCOMES: Quick-DASH, PRWHE, range of motion, grip strength, EQ-5D-3L. RESULTS: 148 patients were screened from November 2019 to March 2021. 48 patients did not want to participate or were unable to participate in the follow-up. 100 patients were randomized and 85 patients were available for full analysis due to there being 4 deaths, 6 withdrawals, 1 wrong inclusion, 1 emigration, 1 refracture, 1 patient with compartment syndrome, and 1 who was advised to undergo surgery after being randomized to non-operative treatment. Median age was 74 years (range 65-92), 81 women/19 men, 42 right/58 left side, 87 retired, 11 smokers, 86 ASA class 1 or 2. Complication rates did not statistical significantly vary between the operative and non-operative group: 20.9% (9/43) vs 16.6% (7/42), p = 0.78 (Fisher's exact test). Complications were driven by sensory disturbances. Four reoperations were performed: two in the non-operative group: carpal tunnel syndrome; two in the operative group: one carpal tunnel syndrome, one protruding screw causing extensor tendon irritation. Mean difference in Quick-DASH varied from 2.3 (95% CI - 3 to 8) pre-injury to 4.2 (- 4 to 12) at 12 months. Quick-DASH and PRWHE were neither statistically nor clinically-relevant different between groups. CONCLUSIONS: Complication rates after operative and non-operative treatment of DRF were similar. Volar plating did not improve the functional outcome after 5 weeks, 6 months, and 12 months. These findings are in line with recent RCTs and mandate a revision of guidelines towards more conservative treatment. TAKE HOME MESSAGES: (1) consider non-operative treatment in elderly patients sustaining unstable DRFs; (2) choosing operative treatment in patients older than 65 years should not be the gold standard; (3) however, non-operative treatment still carries a risk for complications.
