    Abstract

    To compare clinical and radiological outcome between acetabular fractures with marginal impaction that were treated with either cancellous bone graft (CBG) or tricalcium phosphate cement (TPC) as bone void filler.Retrospective study.Forty-three patients with acetabular fractures with marginal impaction.Eighteen patients received cancellous bone graft and 25 patients received tricalcium phosphate cement as bone void filler.Clinical outcome was assessed using the Merle d'Aubigne score and Short-form-36. Radiographs were evaluated for postoperative reduction, arthritis grade and development of heterotopic ossification.Forty-three patients met the inclusion criteria. There was no significant difference in the demographics, laterality, fracture type, associated injuries, surgical approach and postoperative quality of reduction between the groups. At final follow-up, a significantly higher number of patients in the cancellous bone graft group exhibited signs of moderate to severe post-traumatic arthritis (CBG: 6 (33%) vs. TPC: 4 (20%), p=0.007) and required a total hip arthroplasty (CBG: 4 (22.2%) vs. TPC: 1 (5%), p=0.08). There was no significant difference between the two groups in the SF-36 score and the modified Merle d'Aubigne score.Patients with acetabular fractures with marginal impaction treated with tricalcium phosphate cement exhibit a significantly lower incidence of post-traumatic arthritis when compared to patients treated with cancellous bone graft.III.

  • Risk factors for development of heterotopic ossification of the elbow after fracture fixation JOURNAL OF SHOULDER AND ELBOW SURGERY Abrams, G. D., Bellino, M. J., Cheung, E. V. 2012; 21 (11): 1550-1554

    Abstract

    Postoperative heterotopic ossification (HO) about the elbow may occur after surgical fixation of fractures and can contribute to dysfunction. Factors associated with HO formation after surgical fixation of elbow trauma are not well understood.All patients who underwent surgery for elbow trauma at our institution from October 2001 through August 2010 were retrospectively reviewed. Patients with prior injury or deformity to the involved elbow were excluded. Demographic data; fracture type; surgical treatment; and presence, location, and size of HO were recorded. The Fisher exact test, ?(2) test, and multivariate logistic regression were used with an ? value of .05 used for significance.A total of 159 patients were identified, with 89 (37 men and 52 women) meeting inclusion and exclusion criteria. The mean age was 54.4 years (range, 18-90 years), and the mean follow-up time was 180 days. Age, male gender, lateral collateral ligament repair, and dual-incision approach were not associated with increased ectopic bone formation. Distal humeral fractures were a significant predictor of heterotopic bone. In patients in whom HO ultimately developed, it was visible on radiographs obtained 2 weeks postoperatively in 86% of cases.This investigation found predictors for the development of HO after surgical fixation of intra-articular elbow fractures. Furthermore, HO went on to develop at the time of final follow-up in only 14% of patients without HO on radiographs obtained 2 weeks postoperatively. This may suggest that absence of HO on radiographs obtained 2 weeks postoperatively may predict a more favorable outcome.

    Abstract

    The objective of this study was to determine whether one can achieve stable fixation of a two column (transverse) acetabular fracture by only fixing a single column with a locking plate and unicortical locking screws. We hypothesized that a locking plate applied to the anterior column of a transverse acetabular fracture would create a construct that is more rigid than a non-locking plate, and that this construct would be biomechanically comparable to two column fixation.Using urethane foam models of the pelvis, we simulated transverse acetabular fractures and stabilized them with 1) an anterior column plate with bicortical screws, 2) an anterior locking plate with unicortical screws, 3) an anterior plate and posterior column lag screw, and 4) a posterior plate with an anterior column lag screw. These constructs were mechanically loaded on a servohydraulic material testing machine. Construct stiffness and fracture displacement were measured.We found that two column fixation is 54% stiffer than a single column fixation with a conventional plate with bicortical screws. There was no significant difference between fixation with an anterior column locking plate with unicortical screws and an anterior plate with posterior column lag screw. We detected a non-significant trend towards more stiffness for the anterior locking plate compared to the anterior non-locking plate.In conclusion, a locking plate construct of the anterior column provides less stability than a traditional both column construct with posterior plate and anterior column lag screw. However, the locking construct offers greater strength than a non-locking, bicortical construct, which in addition often requires extensive contouring and its application is oftentimes accompanied by the risk of neurovascular damage.

  • Requests for 692 transfers to an academic Level I trauma center: Implications of the Emergency Medical Treatment and Active Labor Act JOURNAL OF TRAUMA-INJURY INFECTION AND CRITICAL CARE Spain, D. A., Bellino, M., Kopelman, A., Chang, J., Park, J., Gregg, D. L., Brundage, S. I. 2007; 62 (1): 63-67

    Abstract

    The Emergency Medical Treatment and Active Labor Act (EMTALA) effectively requires Level I trauma centers (TC) to accept all transfers for a higher level of care if capacity exists. We hypothesized that EMTALA would burden a Level I TC by a selective referral of a poor payer mix of primarily nonoperative patients.All transfer calls (December 2003 and September 2005) to our Level I TC are handled by a dedicated transfer center. Calls were reviewed for age, surgical service requested, and outcome of request. The trauma registry was queried to compare Injury Severity Scale (ISS) score, hospital stay (LOS), operations, mortality, and payer status for transfer and primary catchment patients.In all, 821 calls were received; 77 calls were cancelled by the referring hospital and 52 were for consultation only. Of the 692 transfer requests, 534 (77%) were accepted, 134 (19%) were denied for no capacity, and only 24 (4%) were declined by TC as not clinically indicated. Transferred patients were younger (32.0 +/- 1.49 versus 38.9 +/- 0.51, p < 0.05), had similar ISS scores (13.6 +/- 0.62 versus 13.7 +/- 0.26) and LOS (7.0 +/- 0.70 versus 7.4 +/- 0.25), but were somewhat more likely to require an operation than direct admissions (58% versus 51%, p < 0.05). Although trauma (24%) and neurosurgery (24%) were the most commonly requested services, followed by orthopedics (20%), orthopedics accounted for 60% of operations on transferred patients compared with 10% to 13% for trauma and neurosurgery (mostly spine). There was no difference in the payer status of transfer and direct admit patients.Contrary to our assumptions, EMTALA patients had an identical payer mix and similar operative need compared with our primary catchment patients. They do represent a large additional patient load (20% of admissions) and differentially impact specialists, mostly operative for orthopedics and complex nonoperative care for trauma and neurosurgery. These data suggest that the primary motivations for transfer are specialist availability and complexity of care rather than financial concerns. As TCs provide backup specialty call coverage for a wide geographic area, this further supports the need for trauma systems development.
