Management of humeral impending or pathological fractures with intramedullary nailing: reaming versus non reaming technique-a retrospective comparative study
To compare reamed intramedullary nailing (RIM) versus un-reamed intramedullary nailing (URIM) for the treatment of impending and pathological fractures of the humeral shaft in terms of 24-h postoperative pain, blood transfusion requirements, surgical time, surgical complications, medical complications, length of stay and consolidation rates.
A retrospective comparative study between January 2013 and December 2018 was conducted. Student's t test, Mann-Whitney U and Chi-square tests were used to detect differences within the two study groups. Multiple linear regression was done to adjust for possible confounders.
A total of 53 patients (33 RIM vs. 20 URIM) underwent humeral nailing. Fifteen (28%) were impending fractures (7 RIM vs. 8 URIM). Multiple myeloma (49%) and metastatic carcinoma (39.6%) were the most common etiologies. Pain score (5.13 ± 0.68 RIM vs. 6.78 ± 0.62 URIM; p = 0.082) and total dose of opioids (33.125 ± 27.6 RIM vs. 33.3 ± 22.28 URIM; p = 0.462) showed similar results. Blood transfusion was more prevalent within RIM group (34.48% RIM vs. 20% URIM; p = 0.044) with a clinical tendency of higher blood loss (207.86 ± 150.83RIM vs. 127.00 ± 179.98 URIM; p = 0.092). There was a consolidation rate of 71.05% (27/38) with no statistical difference (73.08% (19/26) RIM vs. 66.67% (8/12) URIM; p = 0.685).
Our study suggests possible benefit of URIM in terms of less blood transfusions with no difference in consolidation rates. Even though without significance, a tendency to less blood loss, less events of systemic complication and lower length of stay was observed with URIM. Despite its limitations, this study can be used to design future prospective ventures that quantify patient-reported outcomes and provide more clear evidence

Treatment strategies for central low-grade chondrosarcoma of long bones: a systematic review of the literature and meta-analysis
The need for wide local excision (WLE) versus intralesional (IL) treatment of low-grade chondrosarcomas (CS) of the appendicular skeleton remains controversial. We sought to perform a systematic review and meta-analysis to compare different conventional types of surgical treatments for grade I CS in terms of: (1) rate of local recurrence (LR) and metastases, (2) functional outcome as measured by the Musculoskeletal Tumor Society (MSTS) score, (3) complication rate. Eighteen studies enrolling 695 patients met our criteria. Studies reported on WLE versus IL treatment (n = 7), and IL treatment with or without different adjuvants (N = 11). The LR rate was not significantly different between WLE and IL treatment (OR 2.31; 95% CI, 0.85-6.2; P = 0.1). On the contrary, complication rates were significantly lower in favor of IL treatment (OR 2.27; 95% CI, 0.07-0.72; P = 0.012). The mean reported MSTS score ranged from 21.8 to 28.2 for WLE and from 26.5 to 29.7 for IL treatment, with a significant difference in favor of IL treatment. IL treatment as an alternative to WLE does not greatly increase the risk of LR or metastasis and has lower complication rates with better functional scores. In light of the retrospective nature of the studies available, our findings should be interpreted with caution

Treatment modalities and outcomes of pleomorphic hyalinizing angiectatic tumor: a systematic review of the literature
A systematic review of the cases documented in the literature regarding Pleomorphic hyalinizing angiectatic tumor of soft parts (PHAT) was performed in order to identify (1) location on presentation (2) surgical treatment modality (3) recurrence rate (4) any associations between location, age, histology, surgery type on recurrence. A systematic review of medical literature listed on PubMed was conducted identifying any prior case report and/or case series of diagnosed PHAT, with no exclusion based on language or time. Twenty-nine articles were identified removing any articles with duplicated cases yielding a total of 93 cases. Cases were broken down by gender, presenting location (UE/LE/axial), surgery type [wide local resection, non-wide local, wide local with radiation therapy (RT), non-wide local with RT], recurrence, and time to recurrence. The mean age at presentation was 54.5 ± 17.1 (range 10-89) with the 76% of cases appearing in the lower extremity (15% UE, 9% Axial). Of the 93 patients, 74 had a known surgical procedure, 31% WL, 40% NWL, 8% WL + RT, 1% NWL + RT. Of those treated surgically, 63 pts had documented follow-up and 18 (29%) had recurrence. A strong association was observed between surgery type and recurrence. Local recurrence was more common within the group undergoing NWLE in 52% (16/41) of cases (p = 0.002). Kaplan-Meier analysis showed an estimate mean time for recurrence of 43.87 months [95% confidence interval (CI) 24.52-63.22; and standard error (SE) 7.59] for the entire population. A trend was also seen toward males having a shorter disease-free survival than females (29.4 mos. vs. 69.5 mos.). No significant association seen between size, location, histology type and recurrence. PHAT has a characteristic presentation in the LE with a relatively high rate of local recurrence and slow-growing potential. Wide local excision appears to be superior in decreasing recurrence rates and a long-term follow-up period is needed

Proximal Tibial Reconstruction After Tumor Resection: A Systematic Review of the Literature
The proximal part of the tibia is a common location for primary bone tumors, and many options for reconstruction exist following resection. This anatomic location has a notoriously high complication rate, and each available reconstruction method is associated with unique risks and benefits. The most commonly utilized implants are metallic endoprostheses, osteoarticular allografts, and allograft-prosthesis composites. There is a current lack of data comparing the outcomes of these reconstructive techniques in the literature.
A systematic review of peer-reviewed observational studies evaluating outcomes after proximal tibial reconstruction was conducted, including both aggregate and pooled data sets and utilizing a Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) review for quality assessment. Henderson complications, amputation rates, implant survival, and functional outcomes were evaluated.
A total of 1,643 patients were identified from 29 studies, including 1,402 patients who underwent reconstruction with metallic endoprostheses, 183 patients who underwent reconstruction with osteoarticular allografts, and 58 patients who underwent with reconstruction with allograft-prosthesis composites. The mean follow-up times were 83.5 months (range, 37.3 to 176 months) for the metallic endoprosthesis group, 109.4 months (range, 49 to 234 months) for the osteoarticular allograft group, and 88.8 months (range, 49 to 128 months) for the allograft-prosthesis composite reconstruction group. The mean patient age per study ranged from 13.5 to 50 years. Patients with metallic endoprostheses had the lowest rates of Henderson Type-1 complications (5.1%; p < 0.001), Type-3 complications (10.3%; p < 0.001), and Type-5 complications (5.8%; p < 0.001), whereas, on aggregate data analysis, patients with an osteoarticular allograft had the lowest rates of Type-2 complications (2.1%; p < 0.001) and patients with an allograft-prosthesis composite had the lowest rates of Type-4 complications (10.2%; p < 0.001). The Musculoskeletal Tumor Society (MSTS) scores were highest in patients with an osteoarticular allograft (26.8 points; p < 0.001). Pooled data analysis showed that patients with a metallic endoprosthesis had the lowest rates of sustaining any Henderson complication (23.1%; p = 0.009) and the highest implant survival rates (92.3%), and patients with an osteoarticular allograft had the lowest implant survival rates at 10 years (60.5%; p = 0.014).
Osteoarticular allograft appears to lead to higher rates of Henderson complications and amputation rates when compared with metallic endoprostheses. However, functional outcomes may be higher in patients with osteoarticular allograft. Further work is needed using higher-powered randomized controlled trials to definitively determine the superiority of one reconstructive option over another. In the absence of such high-powered evidence, we encourage individual surgeons to choose reconstructive options based on personal experience and expertise.

Surgical treatment of low-grade chondrosarcoma involving the appendicular skeleton: long-term functional and oncological outcomes
The traditional treatment for chondrosarcoma is wide local excision (WLE), as these tumors are resistant to chemotherapy and radiation treatment. While achieving negative margins has traditionally been the goal of chondrosarcoma resection, multiple studies have demonstrated good short-term results after intralesional procedures for low-grade chondrosarcomas (LGCS) with curettage and adjuvant treatments (phenol application, cauterization or cryotherapy) followed by either cementation or bone grafting. Due to the rarity of this diagnosis and the recent application of this surgical treatment modality to chondrosarcoma, most of the information regarding treatment outcomes is retrospective, with short or intermediate-term follow-up. The aim of this study was to assess the long-term results of patients with LGCS of bone treated with intralesional curettage (IC) treatment versus WLE. This retrospective analysis aims to characterize the oncologic outcomes (local recurrence, metastases) and functional outcomes in these two treatment groups at a single institution.
Using an institutional musculoskeletal oncologic database, we retrospectively reviewed medical records of all patients with LGCS of the appendicular skeleton that underwent surgical treatment between 1985 and 2007. Thirty-two patients (33 tumors) were identified with LGCS; 17 treated with IC and 15 with WLE.
Seventeen patients (18 tumors) with a minimum clinical and radiologic follow-up of 10Â years were included. Nine patients were treated with IC (four with no adjuvant, three with additional phenol, one with liquid nitrogen and one with H
O
) with either bone graft or cement augmentation, and nine others were treated with WLE and reconstruction with intercalary/osteoarticular allograft or megaprosthesis. The mean age at surgery was 41 years (range 14-66 years) with no difference (p = 0.51) between treatment cohorts. There was a mean follow-up of 13.5 years in the intralesional cohort (range 10-19 years) and 15.9 years in the WLE cohort (range 10-28 years, p = 0.36). Tumor size varied significantly between groups and was larger in patients treated with WLE (8.2 ± 3.1 cm versus 5.4 ± 1.2 cm, at the greatest dimension, p = 0.021). There were two local recurrences (LR), one in the intralesional group and one in the wide local excision group, occurring at 3.5 months and 2.9 years, respectively, and both required revision. No further LR could be detected with long-term follow-up. The MSTS score at final follow-up was significantly higher for patients managed with intralesional procedures (28.7 ± 1.7 versus 25.7 ± 3.4, p = 0.033). There were less complications requiring reoperation in the intralesional group compared with the wide local excision group, although this difference was not found to be statistically significant (one versus four patients, respectively; p = 0.3).
This series of low-grade chondrosarcoma, surgically treated with an intralesional procedures, with 10-year follow-up, demonstrates excellent local control (88.9%). Complications were infrequent and minor and MSTS functional scores were excellent. Wide resection of LGCS was associated with lower MSTS score and more complications. In our series, the LR in both groups were detected within the first 3.5Â years following the index procedure, and none were detected in the late surveillance period
Distal metaphyseal radius fractures in children following closed reduction and casting: can loss of reduction be predicted?
PURPOSE: The aim of this study was to identify factors which contribute to loss of reduction (LOR). METHODS: Outpatient records and initial, post-reduction (PR) and follow-up radiographs of patients with a distal radial metaphyseal fracture were reviewed to determine demographic factors; fracture characteristics (obliquity, comminution, intact ulna); three-point cast index (3PI); and initial, PR, and follow-up displacement (angulation and translation in the sagittal and coronal planes). Univariate and multivariate regression were used to identify significant risk factors for LOR. RESULTS: A total of 161 patients were included in our series (119 boys and 42 girls). Fifty-seven (35%) patients met the criteria for LOR. Multivariate logistic regression revealed that patients over 14 years old were 4.8 times more likely (p = 0.01) to lose reduction, and those with more than 10% PR translation in the sagittal plane were four times more likely (p = 0.03) to lose reduction. In younger patients, initial coronal translation and PR sagittal translation were independent risk factors. Patients with over 10% initial translation in the coronal plane were 2.4 times more likely (p = 0.01) to lose reduction, and those with over 10% PR translation in the sagittal plane were 2.7 times more likely (p = 0.03) to lose reduction. Three point cast index was not found to be a significant risk factor (1.64 vs. 1.57, p = 0.43). CONCLUSION: Our study, the largest dedicated series of distal radial metaphyseal fractures, indicates that loss of reduction is common. Our analysis suggests that an anatomical reduction, which minimises residual translation, is the most important variable in preventing a loss of reduction
