RESUMO
Leiomyosarcomas are smooth muscle-derived tumors generally found intra-abdominally in the retoperitoneum, mesentery, or omentum. Only approximately 5% of these tumors originate from vessel wall smooth muscle. Those derived from the splenic vein are exceedingly rare, with only one previously published case in the literature. We present a second case of leiomyosarcoma of the splenic vein in a 58-year-old woman with 2 months of epigastric pain. A distal pancreatectomy was performed to include the tumor found centered in the splenic vein at the splenic and portal vein confluence and growing into the pancreas in the body on the posterior aspect. A saphenous vein patch was used for reconstruction.

SUMMARY: Decision-making in the treatment of proximal humerus fractures can be challenging. A careful assessment of the patient's anticipated activity and specific fracture features can help determine which treatment strategy best aligns with an individual's goals. Treatment of geriatric proximal humerus fractures is dependent on these factors and an awareness of one's own technical ability.

OBJECTIVE: A meta-analysis and systematic review was performed to compare outcomes of open reduction and internal fixation (ORIF), hemiarthroplasty (HA), and reverse total shoulder arthroplasty (rTSA) for complex proximal humerus fractures. Data sources: MEDLINE, Embase, and Cochrane Library databases were screened. Search terms included reverse total shoulder arthroplasty, open reduction internal fixation, hemiarthroplasty, and proximal humerus fracture. STUDY SELECTION: English-language studies published within the past 15 years evaluating outcomes of ORIF, rTSA, or HA for complex proximal humerus fractures with minimum of 1-year follow-up were included, resulting in 51 studies with 3064 total patients. Review articles, basic science studies, biomechanical studies, and cadaveric studies were excluded. DATA EXTRACTION: The methodological quality of evidence was assessed using the Jadad scale and methodological index for nonrandomized studies. DATA SYNTHESIS: Demographic data were compared using the χ2 test. Mean data were weighted by study size and used to calculate composite mean values and confidence intervals. Continuous data were compared using the Metan module with fixed effects. Count data were compared using the Kruskal-Wallis test. Alpha was set at 0.05 for all tests. CONCLUSIONS: Patients undergoing rTSA had lower risks of complication (relative risk 0.41) and reoperation (relative risk 0.28) than HA patients. rTSA resulted in higher Constant scores (standard mean difference 0.63) and improved active forward flexion when compared with HA (standard mean difference 0.76). Pooled mean data demonstrated better outcome scores and active forward flexion of ORIF versus HA and rTSA, although the patients were younger and had more simple fracture patterns. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

This study sought to determine (1) whether surgeons can accurately predict functional outcomes of operative fixation of pilon fractures based on injury and initial postoperative radiographs, (2) whether the surgeon's level of experience is associated with the ability to successfully predict outcome, and (3) the association between patients' demographic and clinical characteristics and surgeons' prediction scores. A blinded, randomized provider survey was conducted at a level I trauma center. Seven fellowship-trained orthopedic traumatologists and 4 orthopedic trauma fellows who were blinded to outcome reviewed data regarding 95 pilon fractures in random order. Injury ankle radiographs, initial postoperative fixation radiographs, and brief patient histories were assessed. Midterm follow-up functional outcome scores obtained a mean 4.9 years after surgery were available for all patients. Main outcome measures were Pearson correlation coefficient-assessed functional outcomes and surgeon-predicted outcomes. A mixed-effect model determined the association between patients' characteristics and surgeons' prediction scores. Minimal positive correlation was observed between functional outcomes and prediction scores. No difference was noted between the attending and fellow groups in prediction ability. When surgeons' prediction confidence level was greater than 1 SD above the mean confidence level, correlation between functional outcome and prediction improved, although poor correlation was still observed. AO/OTA type 43C fractures, high-energy mechanisms, and older patient age were characteristics associated with lower prediction scores. Surgeons had poor ability to predict functional outcomes of patients with pilon fractures based on injury and initial postoperative radiographs, and level of experience was not associated with ability to predict outcome.

OBJECTIVE: A new closed reduction technique for anterior glenohumeral dislocations and tuberosity fracture dislocations is introduced. METHODS: Forty-one consecutive patients with an acute anterior glenohumeral dislocation or tuberosity fracture dislocation underwent closed reduction by an orthopaedic surgeon employing this new method. RESULTS: Closed reduction was successful in 88% of patients using the reduction maneuver. Associated fracture with glenohumeral dislocation did not influence the success rate of the reduction maneuver. An assistant was needed in 15% of cases. No complications related to the reduction maneuver were noted amongst the cohort. CONCLUSION: This novel reduction technique is safe demonstrating excellent success rates both for anterior shoulder dislocations and tuberosity fracture-dislocations.

UNLABELLED: Dead space is defined as the residual tissue void after tissue loss. This may occur due to tissue necrosis after high-energy trauma, infection, or surgical debridement of nonviable tissue. This review provides an update on the state of the art and recent advances in the management of osseous and soft tissue defects. Specifically, our focus will be on the initial dead space assessment, provisional management of osseous and soft tissue defects, techniques for definitive reconstruction, and dead space management in the setting of infection. LEVEL OF EVIDENCE: Therapeutic Level V. See Instructions for Authors for a complete description of levels of evidence.

Negative pressure wound therapy (NPWT) is a useful management tool in the treatment of traumatic wounds and high-risk incisions after surgery. Since its development nearly 2 decades ago, uses and indications of NPWT have expanded, allowing its use in a variety of clinical scenarios. In addition to providing a brief summary on its mechanism of action, this article provides a focused, algorithmic approach on the use of NPWT by reviewing the available data, the appropriate clinical scenarios and indications, and the specific strategies that can be used to maximize outcomes.
