RESUMEN
OBJECTIVES: Historically, pelvic ring fractures (PRF) are considered to occur predominantly in the anterior ring and therfore to be mechanically stable. Combined anterior and posterior (A + P) PRF are expected to be less mechanically stable and therefore to be associated with higher levels of pain and reduced mobility compared to isolated anterior fractures. The current study investigates the clinical relevance of combined A + P PRF in elderly patients. METHODS: A prospective multicentre cohort study was conducted in patients >70 years of age with anterior PRF after low-energy trauma diagnosed on conventional radiographs. All patients underwent an additional CT-scan. Patients were divided into two groups; isolated anterior or combined A + P fractures. Patients were treated conservatively with adequate analgesia for at least one week. If patients could not be mobilised after conservative treatment, surgical fixation was performed. Numerical Rating Scale (NRS) pain scores, dependence on walking aids and Activities of Daily Living scores (ADL) were measured at 2-4 weeks, and 3, 6 and 12 months after fracture. RESULTS: 102 patients (age 81.1 ± 7.6 years) were included. Isolated anterior fractures were diagnosed in 25 (24.5%) and A + P fractures in 77 (75.5%) patients. Baseline characteristics did not differ between the two groups. Most patients were successfully treated conservatively and 5 (4.9%) underwent percutaneous trans-iliac, trans-sacral screw fixation after failure of conservative treatment. At 2-4 weeks post trauma, patients with A + P fractures had similar median pain scores (3 (range 0-8) vs. 5 (0-10), p = 0.19) and ADL scores (85 (25-100) vs. 78.6 (5-100), p = 0.67), but were more dependent on walking aids (92.8% vs. 72.2%; p = 0.02) compared to patients with isolated anterior fractures. There were no significant differences at 3 months. At one year follow-up the median NRS pain and ADL scores for both fracture groups were 0 and 100, respectively. Mortality was 10.8%, and additional loss to follow-up was 17.6%. CONCLUSIONS: The vast majority of elderly patients with PRF have combined A + P fractures. The clinical implications of additional posterior pelvic ring fractures in elderly patients appears to be limited.

Background: Surgical-site infection (SSI) is a serious surgical complication that can be prevented by preoperative skin disinfection. In Western European countries, preoperative disinfection is commonly performed with either chlorhexidine or iodine in an alcohol-based solution. This study aimed to investigate whether there is superiority of chlorhexidine-alcohol over iodine-alcohol for preventing SSI. Methods: This prospective cluster-randomized crossover trial was conducted in five teaching hospitals. All patients who underwent breast, vascular, colorectal, gallbladder or orthopaedic surgery between July 2013 and June 2015 were included. SSI data were reported routinely to the Dutch National Nosocomial Surveillance Network (PREZIES). Participating hospitals were assigned randomly to perform preoperative skin disinfection using either chlorhexidine-alcohol (0·5 per cent/70 per cent) or iodine-alcohol (1 per cent/70 per cent) for the first 3 months of the study; every 3 months thereafter, they switched to using the other antiseptic agent, for a total of 2 years. The primary endpoint was the development of SSI. Results: A total of 3665 patients were included; 1835 and 1830 of these patients received preoperative skin disinfection with chlorhexidine-alcohol or iodine-alcohol respectively. The overall incidence of SSI was 3·8 per cent among patients in the chlorhexidine-alcohol group and 4·0 per cent among those in the iodine-alcohol group (odds ratio 0·96, 95 per cent c.i. 0·69 to 1·35). Conclusion: Preoperative skin disinfection with chlorhexidine-alcohol is similar to that for iodine-alcohol with respect to reducing the risk of developing an SSI.
Antecedentes: La infección del sitio quirúrgico (surgical site infection, SSI) es una complicación quirúrgica grave que se puede prevenir mediante una desinfección cutánea preoperatoria. En los países de Europa occidental, la desinfección preoperatoria se realiza habitualmente usando clorhexidina o yodo en una solución a base de alcohol. Nuestro objetivo fue investigar si la clorhexidina alcohólica es superior al yodo con alcohol para prevenir la SSI. Métodos: Este ensayo prospectivo aleatorizado por conglomerados y de grupos cruzados se realizó en cinco hospitales docentes. Se incluyeron todos los pacientes que se sometieron a cirugía mamaria, vascular, colorrectal, biliar y ortopédica entre julio de 2013 y junio de 2015. Los datos de SSI se presentaron de manera rutinaria a la Red Nacional Holandesa de Vigilancia Nosocomial (PREZIES). Los hospitales participantes fueron asignados al azar para realizar una desinfección cutánea preoperatoria con clorhexidina alcohólica (0,5%/70%) o yodo con alcohol (1%/70%) durante los primeros tres meses del estudio; cada 3 meses a partir de entonces, cambiaron a usar el otro agente antiséptico, durante un total de 2 años. El criterio de valoración principal fue el desarrollo de SSI. Resultados: Se incluyeron un total de 3.665 pacientes; 1.835 y 1.830 de estos pacientes recibieron desinfección cutánea preoperatoria con clorhexidina alcohólica o yodo con alcohol, respectivamente. La incidencia global de SSI fue del 3,8% entre los pacientes en el grupo de clorhexidina alcohólica y del 4,0% entre los pacientes en el grupo de yodo con alcohol (razón de oportunidades, odds ratio, OR 0,96; i.c. del 95%: 0,691,35). Conclusión: La desinfección cutánea preoperatoria con clorhexidina alcohólica es similar al yodo con alcohol con respecto a la reducción del riesgo de desarrollar una SSI.

INTRODUCTION: The British Orthopedic Association (BOA) and British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS) updated the evidence-based guidelines for the treatment and care of open lower limb fractures (BOAST 4). Following this, a Dutch version has been developed. The main points are multidisciplinary care, planning, and treatment of these injuries. Early osteosynthesis (within 7-14 days) combined with soft-tissue coverage results in more efficient care and less complications. AIM: To study the variation in treatment and thoughts among trauma, orthopedic, and plastic surgeons. MATERIALS AND METHODS: In this cross-sectional study 94 surgeons (57 trauma, 23 plastic, and 14 orthopedic surgeons) working at 46 centers completed an online questionnaire, consisting of 5 demographic, 14 hospital-related, 8 BOAST 4-related, and 2 centralization-related questions. RESULTS: There was a strong agreement among surgeons about the best moment for multidisciplinary consultation, which was before initial debridement, while in practice, this often does not occur. All surgeons agreed that the initial debridement should be performed immediately by any surgeon, but not solely by trainees. Plastic surgeons responded that the definitive stabilization and wound cover should not exceed 7 days, while half of the trauma and orthopedic surgeons agreed that it should not exceed 14 days. Finally, most surgeons agreed that Gustilo 3 fractures should be centralized. However, there was disagreement on the need for centralization of Gustilo 2 fractures. DISCUSSION: Surgeons agree on better and earlier multidisciplinary treatment of open lower limb fractures and the centralization of Gustilo 3 fractures.

BACKGROUND: A survival estimation for patients with symptomatic long bone metastases (LBM) is crucial to prevent overtreatment and undertreatment. This study analyzed prognostic factors for overall survival and developed a simple, easy-to-use prognostic model. METHODS: A multicenter retrospective study of 1,520 patients treated for symptomatic LBM between 2000 and 2013 at the radiation therapy and/or orthopaedic departments was performed. Primary tumors were categorized into 3 clinical profiles (favorable, moderate, or unfavorable) according to an existing classification system. Associations between prognostic variables and overall survival were investigated using the Kaplan-Meier method and multivariate Cox regression models. The discriminatory ability of the developed model was assessed with the Harrell C-statistic. The observed and expected survival for each survival category were compared on the basis of an external cohort. RESULTS: Median overall survival was 7.4 months (95% confidence interval [CI], 6.7 to 8.1 months). On the basis of the independent prognostic factors, namely the clinical profile, Karnofsky Performance Score, and presence of visceral and/or brain metastases, 12 prognostic categories were created. The Harrell C-statistic was 0.70. A flowchart was developed to easily stratify patients. Using cutoff points for clinical decision-making, the 12 categories were narrowed down to 4 categories with clinical consequences. Median survival was 21.9 months (95% CI, 18.7 to 25.1 months), 10.5 months (95% CI, 7.9 to 13.1 months), 4.6 months (95% CI, 3.9 to 5.3 months), and 2.2 months (95% CI, 1.8 to 2.6 months) for the 4 categories. CONCLUSIONS: This study presents a model to easily stratify patients with symptomatic LBM according to their expected survival. The simplicity and clarity of the model facilitate and encourage its use in the routine care of patients with LBM, to provide the most appropriate treatment for each individual patient. LEVEL OF EVIDENCE: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

The purpose of this study was to evaluate the natural history of rheumatoid disease of the shoulder over an eight-year period. Our hypothesis was that progression of the disease is associated with a decrease in function with time. A total of 22 patients (44 shoulders; 17 women, 5 men, (mean age 63)) with rheumatoid arthritis were followed for eight years. All shoulders were assessed using the Constant score, anteroposterior radiographs (Larsen score, Upward-Migration-Index (UMI)) and ultrasound (US). At final follow-up, the Short Form-36, disabilities of the arm, shoulder and hand (DASH) Score, erythrocyte sedimentation rate and use of anti-rheumatic medication were determined. The mean Constant score was 72 points (50 to 88) at baseline and 69 points (25 to 100) at final follow-up. Radiological evaluation showed progressive destruction of the peri-articular structures with time. This progression of joint and rotator cuff destruction was significantly associated with the Constant score. However, at baseline only the extent of rotator cuff disease and the UMI could predict the Constant score at final follow-up. A plain anteroposterior radiograph of the shoulder is sufficient to assess any progression of rheumatoid disease and to predict functional outcome in the long term by using the UMI as an indicator of rotator cuff degeneration.

Rotator cuff (RC) tears have a high prevalence, and RC repair surgery is frequently performed. Evaluation of deltoid activation has been reported as an easy to measure proxy for RC functionality. Our goal was to test the success of RC repair in restoring muscle function, by assessing deltoid activation with varying arm abduction moment loading tasks in controls and in RC tear patients before and 1 year after RC repair. Averaged rectified electromyography recordings (rEMG) of the deltoid during 2-s isometric arm abduction tasks were assessed in 22 controls and 33 patients before and after RC repair. Changes in deltoid activation as a response to increased arm abduction moment loading (large vs. small moment), without changing task force magnitude, were expressed as: R = (rEMGLarge - rEMGSmall)/(rEMGLarge + rEMGSmall), where R > 0 indicates an increase in muscle activation with larger moment loading. In controls, a significant increase in deltoid activation was observed with large abduction moment loading: R = 0.11 (95 % CI 0.06-0.16). In patients, R was larger: 0.20 (95 % CI 0.13-0.27) preoperatively and 0.16 (95 % CI 0.09-0.22) postoperatively. Increased compensatory deltoid activation was found in pre-operative RC tear patients. The post-operative decrease in compensatory deltoid activation, although not significant, could indicate (partially) restored RC function in at least some patients.

Surgical repair of posterosuperior rotator cuff tears has a poorer outcome and a higher rate of failure compared with repairs of supraspinatus tears. In this prospective cohort study 28 consecutive patients with an irreparable posterosuperior rotator cuff tear after failed conservative or surgical treatment underwent teres major tendon transfer. Their mean age was 60 years (48 to 71) and the mean follow-up was 25 months (12 to 80). The mean active abduction improved from 79° (0° to 150°) pre-operatively to 105° (20° to 180°) post-operatively (p = 0.011). The mean active external rotation in 90° abduction improved from 25° (0° to 70°) pre-operatively to 55° (0° to 90°) post-operatively (p < 0.001). The mean Constant score improved from 43 (18 to 78) pre-operatively to 65 (30 to 86) post-operatively (p < 0.001). The median post-operative VAS (0 to 100) for pain decreased from 63 (0 to 96) pre-operatively to 5 (0 to 56) post-operatively (p < 0.001). In conclusion, teres major transfer effectively restores function and relieves pain in patients with irreparable posterosuperior rotator cuff tears and leads to an overall clinical improvement in a relatively young and active patient group with limited treatment options.

The incidence of (a)symptomatic rotator cuff tears is high, but etiologic mechanisms are unclear and treatment outcomes vary. A practical tool providing objective outcome measures and insight into etiology and potential patient subgroups is desirable. Symptomatic cuff tears coincide with humerus cranialization. Adductor co-activation during active arm abduction has been reported to reduce subacromial narrowing and pain in cuff patients. We present an easy-to-use method to evaluate adductor co-activation. Twenty healthy controls and twenty full-thickness cuff tear patients exerted EMG-recorded isometric arm abduction and adduction tasks. Ab- and adductor EMG's were expressed using the "Activation Ratio (AR)" (-1 ≤ AR ≤ 1), where lower values express more co-activation. Mean control AR's ranged from .7 to .9 with moderate to good test-retest reliability (ICC: .60-.74). Patients showed significantly more adductor co-activation during abduction, with adductor AR's ranging between .3 (teres major) and .5 (latissimus dorsi). In conclusion, the introduced method discriminates symptomatic cuff tear patients from healthy controls, quantifies adductor co-activation in an interpretable measure, and provides the opportunity to study correlations between muscle activation and humerus cranialization in a straightforward manner. It has potential as an objective outcome measure, for distinguishing symptomatic from asymptomatic cuff tears and as a tool for surgical or therapeutic decision-making.

BACKGROUND: Fixation of the mesh in Lichtenstein's inguinal hernioplasty is traditionally performed with polypropylene sutures. A modification of this technique uses staples for securing of the mesh. METHOD: A retrospective comparative study of 149 elective repairs of a primary inguinal hernia was performed: a control group of 67 patients undergoing mesh fixation using sutures and a study group of 82 patients undergoing staple fixation. Operating time, recurrence, postoperative pain, complications and costs were studied. RESULTS: Seven recurrences (11%) occurred in the polypropylene group as compared to one recurrence (1%) in the staple group (P < 0.01). There was a trend of fewer complications in the staple group. Operative time and long-term postoperative pain did not differ significantly between the two groups. The costs per surgery for mesh fixation and skin closure were euro 11.13 for the suture group and euro 24.35 for the staple group. CONCLUSION: Staple fixation of the mesh in Lichtenstein's inguinal hernioplasty can be considered equal to traditional fixation with sutures with regard to operating time and postoperative pain. However, staple fixation seems to show fewer recurrences and fewer complications.

Two patients, a 20-year-old male and a 33-year-old female, were referred to our orthopaedic outpatient clinic and presented with habitual anterior (sub)luxation of the shoulder as a result of humeral avulsion of the inferior glenohumeral ligament (HAGL lesion). Both patients underwent an open surgical procedure in which the ruptured ligament was restored and fixed to its anatomical point of insertion. Six months after the operation both patients had regained normal function in the glenohumeral joint without instability. The HAGL lesion is a relatively uncommon cause of anterior shoulder instability and requires surgical intervention. Recognition during physical examination, additional examination and arthroscopy are essential for a good outcome.
