[Anterior shoulder dislocation: revised Dutch Clinical Guideline in practice]. / Primaire anterieure schouderluxatie.

Shoulder dislocations remain the most frequent of joint dislocations, with anterior displacement of the humeral head being the direction of dislocation seen most often (97%). Recently, the Dutch clinical guideline on shoulder dislocations has been revised on the basis of predetermined bottlenecks in clinical practice. In this paper, the guideline is translated to clinical practice by means of two fictional cases, in which the novel recommendations are incorporated. The following topics were systematically assessed based on the best available scientific evidence: primary diagnostics, reduction techniques, painmedication/ sedation surrounding reduction and the need for physiotherapy, stabilization surgery and immobilization. Also, a best practice care pathway is advocated. Since scientific evidence is often inconclusive to provide undebatable therapeutic rules, the committee graded the available evidence and additionally used expert opinion to carefully draft recommendations. The paper concludes with an overview of all the recommendations stated in the updated multidisciplinary guideline.

Fibula allograft in complex three-part and four-part proximal humeral fractures in active patients, a matched case-control study.

Background: About 20% of proximal humerus fractures (PHFs) are unstable and/or markedly displaced and therefore require surgery. Locking plate fixation after anatomical reduction has become the current treatment of choice for these fractures in the active population. However, studies have shown complication rates up to 36%, such as loss of reduction and avascular necrosis. To date, data from literature are inconclusive on outcomes following the use of an intramedullary fibula allograft in PHFs, possibly due to the case mix. It is hypothesized that the use of a fibula allograft is beneficial to prevent secondary displacement of the fracture in cases where the medial hinge is markedly displaced and unstable, resulting in better clinical and patient reported outcomes. Methods: In this multicenter matched cohort study, patients with an unstable, displaced PHF, including anatomic neck fractures and significantly displaced surgical neck fractures, were included. Patients that were treated with a locking plate augmented with a fibula allograft were matched to patients who had undergone locking plate reconstruction without the allograft. The matches were made based on fracture characteristics, age, and performance status. Functional outcomes, Patient Reported Outcome Measures, complications, and radiographic results were compared. Results: Twelve patients with fibula allograft augmented osteosyntheses were included and matched to 12 control patients. The mean age was 58 years in the fibula allograft group compared to 62 years in the control group. Minimum follow-up was 12 months. Disability of the Arm Shoulder and Hand score, Constant Shoulder score, abduction, and external rotation were significantly better in the fibula allograft group (17.4 ± 8.6 vs. 26.1 ± 19.2, P = .048; 16.5 ± 11.5 vs. 19.8 ± 16.5 P = .040; mean 127° ± 38° vs. mean 92° ± 49° P = -.045; 50° ± 21° vs. mean 26° ± 23°, P = .004). There was no statistically significant difference in the Oxford Shoulder score between groups (P = .105). The Visual Analog Scale was not significantly different between groups (3.1 ± 1.8 vs. 1.6 ± 1.9, P = .439). Radiographic union was reached in 11 patients of the fibula allograft group compared to 8 in the control group (P = .317). The complication rate was twice as high in the control group (3 vs. 7). Conclusion: Additional support of the medial hinge in unstable PHFs with a locking plate in combination with a fibula allograft appears to create a more stable construct without compromising the viability of the articular surface of the head. The use of a fibula allograft in selected complex cases could therefore result in better clinical outcomes with lower complication rates.

A modified Delphi study to identify which items should be evaluated in shoulder instability research: a first step in developing a core outcome set.

Background: The aim of this study was to identify items that healthcare providers and/or patients consider important to include in a questionnaire for clinical trials and cohort studies in shoulder instability research. This could serve as a basis to develop a core outcome set for shoulder instability research. Methods: Healthcare providers and patients were included in a panel for a modified Delphi consensus study. The study consisted of three rounds, comprising (1) identifying items, (2) rating the importance of the items, and (3) rating the importance again after seeing a summary of the results of round two. Importance was rated on a 9-point Likert scale. Consensus was defined as ≥ 80% of the panel giving a score of 7 or higher. Results: In total, 44 healthcare providers and 30 patients completed all three rounds. Round one identified 54 items. After round three, the panel reached a consensus on 11 items that should be included in a questionnaire, comprising re-dislocation (99%), instable feeling of the shoulder (96%), limitations during sport (93%), patient satisfaction with the shoulder (93%), fear/anxiety for re-dislocation (91%), range of motion (88%), return to old level of functioning (85%), performing daily activities (85%), return to sport (82%), return to work (82%), and trusting the shoulder (81%). Conclusion: Healthcare providers and patients reached a consensus on 11 items that should be included in a questionnaire for shoulder instability research. These items can facilitate design and development of future clinical trials and form the basis for the development of a core outcome set.

The Clinical Outcomes of Operative Treatment Versus Conservative Treatment for Dancer's Fractures: Protocol for a Retrospective Cohort Study.

BACKGROUND: Fifth metatarsal fractures are one of the most common foot fractures, and 11% to 25% of such fractures are Dancer's fractures (distal spiral fractures). Conservative therapy while wearing a cast and operative treatment have been used as preferred modes of treatment in the limited literature available. However, we often see healing problems, such as delayed union and nonunion, when Dancer's fractures are treated nonoperatively, resulting in a need for secondary intervention. In our institution, treatment has changed over the years from predominantly conservative treatment to mostly operative treatment. To investigate whether our hypothesis holds true that primary surgical treatment is beneficial, a retrospective study was designed. OBJECTIVE: The objective of the study is to compare differences between outcomes (delayed union and nonunion) of conservative and operative treatments for Dancer's fractures. METHODS: A retrospective comparative cohort study will be conducted in a level II trauma center (Zaandam Medical Center). Patients who experienced a Dancer's fracture in the period of 2012 to 2021 will be included and divided into 2 cohorts-the conservative (2012-2015) and operative (2016-2021) treatment cohorts. The primary outcome will be the differences in percentages of delayed union and nonunion between the two groups. The secondary outcomes will be the percentage of primary conservative treatment failure, the need for secondary operative treatment, complications (infection and hardware failure), and functional outcomes. If 118 patients are included in each group, sufficient power is expected to be reached, depending on the age distribution of patients. The percentages of delayed union and nonunion among the two groups will be calculated and statistically compared via chi-square statistics. A logistic regression analysis will be used to investigate possible associations between patient characteristics and failed conservative treatment. A Mann-Whitney U test will be used to compare functional outcomes between groups. An independent, 2-tailed t test will be used to compare mean 12-Item Short Form Survey scores if they are normally distributed, and a Wilcoxon rank sum test will be used if they are nonnormally distributed. RESULTS: In total, 2134 potentially relevant health insurance codes have been extracted from the hospital's register. We expect to find a total of 236 Dancer's fractures in this data set. CONCLUSIONS: Our study has limitations due to it being a single-center study and data collection being performed retrospectively. However, it covers a large time period and may provide the possibility to show treatment outcome differences (delayed union and nonunion, complications, and functional outcomes) in 2 reasonably large cohorts (conservative and operative treatment cohorts), which has not been done before in literature on Dancer's fractures. If our hypothesis that surgery is beneficial for Dancer's fractures is proven true by our study, we plan to further corroborate it by conducting a prospective randomized controlled trial.

Posterior tibial plateau fracture treatment with the new WAVE posterior proximal tibia plate: feasibility and first results.

INTRODUCTION: Operative management of posterior tibial plateau fractures (PTPF) remains challenging. The treatment goal is to restore the alignment and articular congruence, and providing sufficient stability which allows early mobilization. The purpose of this study was to assess the feasibility and safety of the newly developed WAVE posterior proximal tibia plate. METHODS: Between Oct 2017 and Jun 2020, 30 adult patients with a tibial plateau fracture and posterior involvement were selected for treatment with a WAVE posterior proximal tibia plate. Patient reported outcome was assessed using the Knee injury and Osteoarthritis Outcome Score (KOOS) at time of injury (pre-injury) and at 1-year follow-up. Radiological outcome was evaluated with CT-imaging. RESULTS: Twenty-eight patients were eligible for treatment with the new implant (3 'one-column', 10 'two column' and 15 'three-column' fractures), whereas in 2 patients anatomical fit was insufficient. KOOS results showed fair outcome scores at 1 year, with a large negative impact compared to pre-injury levels; however, a trend towards better results compared to a previous PTPF reference cohort. Radiological follow-up showed insufficient posterolateral buttress in two cases and residual articular step-off (> 2 mm) in seven patients, of which five were classified as three column fractures. CONCLUSION: Management of PTPF using the WAVE posterior proximal tibia plate is feasible and safe with satisfactory clinical and radiological results after 1 year. Nevertheless, there is a learning curve regarding optimal implant positioning to achieve the maximum benefit of the implant.

Surgical learning curve in reverse shoulder arthroplasty for proximal humerus fractures.

BACKGROUND: Fracture reverse shoulder arthroplasty (fRSA) in geriatric, complex dislocated proximal humerus fractures is becoming the standard treatment next to conservative treatment. fRSA is a multifaceted, reasonably challenging procedure of which functional outcomes and complication rates are likely to depend on the experience of the surgeon. The goal of this study was to determine whether there is a learning curve for fRSA. METHODS: All patients with a dislocated multipart proximal humerus fracture that were treated with an fRSA between 2013 and 2019 in a specialized institution were included. The functional outcomes (Constant Shoulder Score, Oxford Shoulder Score, and range of motion), complications, and operation time of fRSA were assessed with linear regression plots and cumulative summation analysis to establish whether a learning curve was present. RESULTS: In this cohort study, 50 patients were included. They had a mean age of 77.1 years and were treated with an fRSA by one trauma surgeon. Learning curves were distinguished for functional outcomes, complications, and operation time based on learning targets for daily activity and the mean complications and operation time. Results indicated that an optimal treatment is achieved after performing 20 fRSAs. CONCLUSION: The results show that functional outcomes of PHFs treated with an fRSA improve with surgical experience. Also, outcomes are getting less variable after about 20 procedures. Surgeons starting this procedure should be aware of the learning curve and, therefore, should consider guidance from an experienced surgeon to swiftly optimize functional outcomes and prevent unnecessary complications.

WARRIOR-trial - is routine radiography following the 2-week initial follow-up in trauma patients with wrist and ankle fractures necessary: study protocol for a randomized controlled trial.

BACKGROUND: Extremity fractures such as wrist and ankle fractures are a common and costly healthcare problem. The management of these fractures depends on fracture type and loss of congruity of the joint, resulting in cast immobilization or operative treatment. Loss of congruity or displacement leading to uneven joint loading, osteoarthritis and an increased probability of a poor functional outcome should be identified within the first 2 weeks post-trauma, based upon radiographs to determine optimal treatment. After this period, routine radiographs are scheduled for monitoring the bone-healing process. Current protocols describe imaging at 1, 2, 6 and 12 weeks post-trauma. However, it is questionable whether routine radiography following the initial follow-up ( 2-weeks post-trauma) is cost effective. The aim of this study is to determine whether a modification of the radiographic follow-up protocol can be conducted with no worse outcome and less cost than the current standard of care for patients with a wrist or ankle fracture. METHODS/DESIGN: In a multicenter randomized controlled trial, 697 patients aged 18 years or older will be included: 385 wrist fracture- and 312 ankle fracture patients. Patients will be randomized into two groups: Group 1 receives usual care, consisting of radiographs 1, 2, 6 and 12 weeks post-trauma; Group 2 receives radiographs beyond the initial follow-up only when clinically indicated. The primary outcome is the overall extremity-specific function. For wrist fractures, this includes the Disabilities of the Arm, Shoulder and Hand Score; for the ankle fractures, this includes the Olerud and Molander ankle score. Secondary outcomes include: healthcare cost, the specific function measured with the Patient Rated Wrist and Hand Evaluation for wrist fractures and American Academy of Orthopaedic Surgeons foot and ankle questionnaire for ankle fractures, pain-intensity, health-related quality of life, self-perceived recovery, and complications. Both groups will be monitored at 1, 2, and 6 weeks and 3, 6, and 12 months. DISCUSSION: This study will provide data on (cost) effectiveness of routine radiography in the follow-up of wrist and ankle fractures, and could pave the way for a change in (inter)national protocols.

Swim cast versus traditional cast in pediatric distal radius fractures: a prospective randomized controlled trial.

PURPOSE: Non-displaced distal radius fractures in children are traditionally treated in a forearm cast. However, a traditional cast does not tolerate getting wet, with skin lesions and bad smell as result. A Swim cast, which has the ability to dry quickly, is an airy cast that is applied using the MOKcast technique. We hypothesize that Swim casts contribute to higher patient satisfaction scores than traditional casts, without any adverse effects on fracture healing or skin condition. METHODS: A prospective, randomized, single-center, blinded study was conducted to compare traditional and Swim cast treatment in children aged 5-15 years with greenstick or torus fractures of the distal radius. Primary endpoint was the patient and parent satisfaction, as determined by a questionnaire. Secondary endpoints were radiographic and clinical bone healing and cast-related skin conditions. RESULTS: A total of 68 patients, divided into two treatment groups (traditional case and Swim cast; n = 34 per group). Baseline characteristics were similar between the groups. The overall satisfaction score (0-10) reported by the patients was 8.6 in the Swim cast group versus 7.5 in the traditional cast group (p < 0.002); the overall satisfaction score reported by the parents was 8.3 and 7.7, respectively (p < 0.02). There was no difference in radiographic or clinical healing between groups, and skin conditions also did not differ significantly between groups. CONCLUSION: In our patient group, treatment of non-displaced, pediatric, distal radius fractures by Swim cast yielded better patient satisfaction results compared to treatment with the traditional, cotton-lined cast, without adverse effects on fracture healing or skin condition.

Identical fracture patterns in combat vehicle blast injuries due to improvised explosive devices; a case series.

BACKGROUND: In November 2008, a surgical team from the Red Cross Hospital Beverwijk, the Netherlands, was deployed in Afghanistan for three months to attend in the army hospital of Kandahar.During their stay, four incidents of armored personnel carriers encountering an improvised explosive device were assessed. In each incident, two soldiers were involved, whose injuries were strikingly similar. CASE PRESENTATION: The described cases comprise paired thoracic vertebral fractures, radial neck fractures, calcaneal fractures and talar fractures. Moreover, the different types of blast injury are mentioned and related to the injuries described in our series. Acknowledging the different blast mechanisms is important for understanding possible injury patterns. CONCLUSION: From this case series, as well as the existing literature on injury patterns caused by blast injuries, it seems appropriate to pay extra attention to bodily areas that were injured in other occupants of the same vehicle. Obviously, the additional surveillance for specific injuries should be complementary to the regular trauma work-up (e.g., ATLS).

Specialized emergency nurses treating ankle and foot injuries: a randomized controlled trial.

OBJECTIVE: To cope with emergency departments (EDs) being progressively overcrowded, the concept of specialized emergency nurses (SENs) was conceived. In this study, the ability of SENs to treat ankle/foot injuries was assessed. METHODS: Regular emergency nurses were trained in a 2-day session that addressed all aspects of ankle/foot injuries. A randomized controlled trial was set up in which the diagnostic accuracy of SENs was compared with that of house officers (HOs). Secondary outcome parameter was patient satisfaction measured by a standardized questionnaire. RESULTS: In total, 512 consecutive patients were included. The sensitivity of SENs was 0.94 (95% confidence interval [CI], 0.78-0.99) compared with 0.78 (95% CI, 0.57-0.91) of HOs. Specificity was 0.94 (95% CI, 0.90-0.97) for SENs compared with 0.95 (95% CI, 0.91-0.98) for HOs. The delivered care by SENs was found to be significantly better and the median waiting time at the ED was significantly reduced (21 minutes for SENs vs 32 minutes for HOs). CONCLUSIONS: Specialized emergency nurses are capable of assessing and treating ankle/foot injuries accurately with excellent patient satisfaction and with a reduction of waiting times. Other injury-specific courses are now developed for this approach.

Diagnostic accuracy and reproducibility in the interpretation of Ottawa ankle and foot rules by specialized emergency nurses.

OBJECTIVES: The ED is often confronted with long waiting periods. Because of the progressive shortage in general practitioners, further growth is expected in the number of patients visiting the ED without consulting a general practitioner first. These patients mainly present with minor injuries suitable for a standardized diagnostic protocol. The question was raised whether these injuries can be treated by trained ED nurses (specialized emergency nurses [SENs]). The aim of this study was to evaluate the diagnostic accuracy and reproducibility of SENs in assessing ankle sprains by applying the Ottawa Ankle Rules (OAR) and Ottawa Foot Rules (OFR). METHODS: In a prospective study, all ankle sprains presented in the ED from April to July 2004 were assessed by both a SEN and a junior doctor (house officer [HO]) randomized for first observer. Before the study, SENs were trained in applying OAR and OFR. In all patients, radiography was performed (gold standard). The diagnostic accuracy for the application of OAR and OFR was calculated for both groups and was compared using z statistics. Furthermore, from the paired results, reproducibility was calculated using kappa statistics. RESULTS: In total, 106 injuries were assessed in pairs, of which 14 were ultimately found to concern acute fractures (prevalence, 13%). The sensitivity for the SEN group was 0.93 (95% confidence interval [CI], 0.64-1.00) compared with 0.93 (95% CI, 0.64-1.00) for the HO group (no significance [ns]). The specificity of the nurses was 0.49 (95% CI, 0.38-0.60) compared with 0.39 (95% CI, 0.29-0.50) for the doctors (ns). The positive predictive value for the SEN group was 0.22 (95% CI, 0.13-0.35) compared with 0.19 (95% CI, 0.11-0.31) for the HO group (ns). The negative predictive value for the nurses was 0.98 (95% CI, 0.87-1.00) compared with 0.97 (95% CI, 0.84-1.00) for the doctors (ns). The interobserver agreement for the OAR and OFR subsets was kappa = 0.38 for the lateral malleolus; kappa = 0.30, medial malleolus; kappa = 0.50, navicular; kappa = 0.45, metatarsal V base; and kappa = 0.43, weight-bearing. The overall interobserver agreement for the OAR was kappa = 0.41 and kappa = 0.77 for the OFR. CONCLUSION: Specialized emergency nurses are able to assess ankle and foot injuries in an accurate manner with regard to the detection of acute fractures after a short, inexpensive course.
