RESUMO
PURPOSE: To identify risk factors predisposing patients to poor outcomes after fixation of periprosthetic hip fractures around femoral stems. METHODS: Prospective multicentre cohort study of fractures around a hip replacement stem managed by internal fixation. The primary outcome was one-year mortality, while secondary outcomes were local complications and healthcare burden-related outcomes (nursing facility utilization and hospital length of stay). RESULTS: One-year mortality was 16.2%. Age-adjusted Charlson Comorbidity Index score (OR=1.17; 95%CI=1.03-1.33)), Pfeiffer Short Portable Mental Status Questionnaire (SPMSQ) score (OR=1.16; 1.06-1.28), prosthetic dysfunction (OR=1.90; 1.00-3.61), and postoperative medical complications (OR=1.97; 1.06-3.68) were predictors of mortality. Patients with prior prosthetic dysfunction, lower Pfeiffer SPMSQ scores, Vancouver A fractures, and fractures fixed only using cerclages were at higher risk of local complications, which occurred in 9.3% of cases. Medical (OR=1.81; 1.05-3.13) and local complications (OR=5.56; 2.42-3.13) emerged as consistent risk factors for new institutionalization. Average hospitalization time was 13.9±9.2 days. Each day of fixation delay led to an average 1.4-day increase in total hospitalization. CONCLUSION: Frail periprosthetic hip-fracture patients with poorer functional status, dysfunctional replacements, and postoperative complications are at increased risk of mortality. Postoperative complications are more common in patients with dysfunctional arthroplasties, Vancouver A fractures, and fixation using cerclages alone. Postoperative complications were the most consistent predictor of higher healthcare resource utilization.
RESUMO
Simultaneous and bilateral proximal femoral fractures (PFF) are rare and have scarcely been reported in the literature. A case of a bilateral extracapsular PFF is herein presented. Besides, an exhaustive review of the literature was performed, analyzing the information of all previously reported cases. An 81-year-old woman, who suffered a casual fall, was diagnosed with bilateral PFF consisting of both a subtrochanteric and an intertrochanteric fracture. She underwent concurrent intramedullary fixation for both fractures without any relevant complication and started early ambulation. Simultaneous bilateral extracapsular PFF are exceptional, with only 23 cases described in the current literature. In the elderly, they deserve special attention with treatment strategies in between the ones for unilateral hip fractures and those provided to old multiply injured patients. PFF management is not well established. Minimal reaming and careful nailing can be safely performed bilaterally under close monitoring, in order to start an early functional recovery.
RESUMO
ORTHOUNION is a multicentre, open, comparative, three-arm, randomized clinical trial (EudraCT number 2015-000431-32) to compare the efficacy, at one and two years, of autologous human bone marrow-derived expanded mesenchymal stromal cell (hBM-MSC) treatments versus iliac crest autograft (ICA) to enhance bone healing in patients with diaphyseal and/or metaphysodiaphyseal fracture (femur, tibia, and humerus) status of atrophic or oligotrophic nonunion (more than 9 months after the acute fracture, including recalcitrant cases after failed treatments). The primary objective is to determine if the treatment with hBM-MSCs combined with biomaterial is superior to ICA in obtaining bone healing. If confirmed, a secondary objective is set to determine if the dose of 100 × 106 hBM-MSCs is noninferior to that of 200 × 106 hBM-MSCs. The participants (n = 108) will be randomly assigned to either the experimental low dose (n = 36), the experimental high dose (n = 36), or the comparator arm (n = 36) using a central randomization service. The trial will be conducted in 20 clinical centres in Spain, France, Germany, and Italy under the same clinical protocol. The confirmation of superiority for the proposed ATMP in nonunions may foster the future of bone regenerative medicine in this indication. On the contrary, absence of superiority may underline its limitations in clinical use.
RESUMO
Well-differentiated liposarcomas of the extremities are one of the most frequent types of malignant soft tissue tumors in adults. These tumors are typically locally aggressive and show a tendency to recurrence after surgical excision even though they do not metastasize and very rarely dedifferentiate. Its clinical presentation is generally a progressively growing mass causing aesthetic, functional, or compressive symptoms depending on the tumor's size and localization. Several authors recommend a wide excision with free margins in order to minimize the risk of recurrence, while others report good results and a low rate of recurrence with more conservative or even marginal excision thereby avoiding complications due to surgical site morbidity. We present a retrospective study of 11 patients with a large-sized well-differentiated liposarcoma of the lower limb with a mean follow-up of 3.2 years. The mean size was 22 × 19 × 17 cm, and a marginal resection was made, respecting the affected neurovascular structures, in all cases. Only one recurrence was found and the functional results were 81.6% according to the MSTS functional scale 1 year after surgery. We believe that the marginal excision is a good alternative when the tumor is located near vascular or nerve structures, and as to our experience, it is not associated with elevated recurrences.

INTRODUCTION: At present, surgical treatment of comminuted radial head fractures without associated instability continues to be controversial. When anatomical reconstruction is not possible, radial head excision is performed. However, the appearance of long-term complications with this technique, along with the development of new radial head implants situates arthroplasty as a promising surgical alternative. The purpose of the present study was to compare the mid-term functional outcomes of both techniques. MATERIALS AND METHODS: A retrospective study was performed between 2002 and 2011 on 25 Mason type-III fractures, 11 patients treated with primary radial head resection and 14 who received treatment of the fracture with metal prosthesis. At the end of follow-up, patients were contacted and outcomes evaluated according to: Mayo Elbow Performance Score (MEPS), the Disabilities of the Arm, Shoulder and Hand score (DASH) and strength measurement. Radiographic assessment (proximal migration of the radius, osteoarthritic changes, and signs of prosthesis loosening) was also performed. RESULTS: The average age of the sample was 53.7 years in the resection group, and 54.4 years in the replacement group, with a mean follow-up of 60.3 and 42 months respectively. According to the MEPS scale, there were 6 excellent cases, 3 good and 2 acceptable in the resection group, and 6 excellent cases, 3 good, 3 acceptable, and 2 poor in the prosthesis group. The mean DASH score were 13.5, and 24.8 for the resection and the replacement group respectively. We found one postoperative complication in the resection group (stiffness and valgus instability) and 6 in the replacement group: 3 of joint stiffness, 1 case of prosthesis breakage, and 2 neurological injuries. CONCLUSIONS: Although this is a retrospective study, the high complication rate occurring after radial head replacement in comparison with radial head resection, as well as good functional results obtained with this last technique, leads us to recommend it for comminuted radial head fractures without associated instability.

Vasculopathic syndromes have been associated with hematological and solid organ malignancies. The pathogenesis of these syndromes remains largely unknown and there are no biologic markers identified. Whether it is or is not a paraneoplastic syndrome is under discussion, the close temporal relationship of cancer and vasculitis suggests that these vasculitides are a paraneoplastic condition. We report a case of a 45-year-old female patient with pelvic chondrosarcoma who underwent surgical treatment and started to present visual loss, systemic inflammatory response syndrome (SRIS), cardiac insufficiency, hepatosplenomegaly, cholestasis as well as pulmonary bleeding suggesting a sarcoma-associated vasculitis. All antibodies were negative as in secondary vasculitis. After corticoideal therapy the vasculitis resolved and at 3-year follow-up the patient had not showed any further medical complications or recurrences of the vasculitis. The parallel evolution of the vasculitis and the solid tumor combined with the resolution of the vasculitis after corticotherapy enhances the likelihood of a paraneoplastic vasculitis associated with a chondrosarcoma according to literature review.
RESUMO
PURPOSE: Reverse shoulder arthroplasty (RSA) in fractures is especially indicated in patients of advanced age, although the influence of age on functional outcomes, health-related quality of life (HRQoL) and complication rate is unknown. We hypothesized that complication rate would decrease in the geriatric population because of their reduced activity, improving the perceived HRQoL. METHODS: Retrospective study of 42 patients with proximal humeral fractures treated with RSA, divided into two groups: <80 years (<80y)(n = 16) and ≥80 years (≥80y)(n = 26). The assessment tools used were radiological images (functional outcome) with the Constant-Murley score(CMS); disabilities of the arm, shoulder and hand (DASH) score; and HRQoL with the EQ-5D index. Mean follow-up time was 32.6 months. RESULTS: Mean CMS adjusted for age and sex (R-CMS) was 68 % ± 29 %. Patients in the ≥80y group had a lower total CMS, 33 vs 64 (p = 0.027). Mean active range of motion at 24 months <80y/≥80y was: forward flexion: 126°/110°; abduction: 117°/105°; external rotation: 22°/20°; and internal rotation: L3/sacrum. Mean EQ-VAS was 74 ± 16 in the <80y group, and 63 ± 12.6 in the ≥80y group. Mean DASH was 29.5 ± 9.2. The EQ-5D "self-care" item in the >80y group was the most affected. The "pain/discomfort" item was lower for the two age groups than for the reference population. There were 9.5 % complications: one prosthesis dislocation, one periprosthetic fracture and two surgical wound haematoma. CONCLUSIONS: Our results indicate that age is a critical factor for RSA success. Lower functional outcomes have been obtained in patients older than 80y, although the EQ-5D results in our sample were similar or even better than the referred population. LEVEL OF EVIDENCE: Level III.

PURPOSE: We report our experience analysing the risk of fracture amongst allografts in limb-preserving surgery for bone tumours. METHODS: We retrospectively reviewed our experience with bone allograft and its major complications when used for limb -preserving operations for bone tumours. Forty-one structural allografts were performed in 39 patients between 1992 and 2012. Minimum follow-up was 20 months. Massive allografts have a high complication rate. RESULTS: Excluding infection and nonunion, five acute fractures were found. All fractures occurred after the graft-host junction was united. Local factors-such as graft preservation, weight bearing, fixation to the host or systemic factors such as adjuvant treatments (chemotherapy or radiotherapy)-influence fracture rate. In our study, four patients achieved consolidation with internal fixation and autologous iliac-crest graft, whilst only one required graft exchange. DISCUSSION: There is no general consensus as to when to treat fractures using open reduction and internal fixation or by exchanging the allograft. Higher fracture rate in relation to systemic treatment was found. CONCLUSIONS: Massive structural allograft reconstruction still has a place in limb-preserving surgery, with an acceptable fracture rate and a durable solution.

BACKGROUND: Intramedullary nailing of displaced proximal humerus fractures is an attractive option in the elderly patient. However, in recent reports, some existing intramedullary nails have shown high rate of complications, so new designs are being developed. The objective of the present study is to report on outcomes and complications when comparing a straight to a curvilinear nail design. METHODS: We prospectively include 54 patients with Neer's 2- or 3-part proximal humerus fractures. Two were lost to follow-up, 26 were surgically treated with a new straight humeral nail (MultiLoc, Synthes) mean age 69 (range, 47-87 years), and 26 with a curvilinear nail (Polarus, Acumed) mean age 71 (range, 38-89 years). At final follow-up (average 14 months), patients underwent a clinical and radiographic evaluation. Clinical outcome was assessed with the adjusted Constant score. RESULTS: All but 1 fracture went on to radiographic union. Mean Constant score in the Polarus nail was 72.7 ± 16.0 and 83.3 ± 16.7 in the MultiLoc (P = .246). Symptoms related with rotator cuff disease were present in 19/26 patients (73%) and in 9/26 (34.6%), respectively (P = .001). The mean neck-shaft angle at final follow-up was 135° in the MultiLoc group and 130° in the Polarus group (P > .05). Reoperation rate was 42% for Polarus and 11.5% for MultiLoc. CONCLUSION: Straight intramedullary nails had a comparable union rate to an accepted curvilinear design, with a much lower incidence of complications. Rotator cuff pain and dysfunction can be minimized with the use of newer generation straight nails.
