Diaphyseal fractures of the distal humerus have a high rate of union when treated with a functional brace or an above-elbow cast (AEC). This study compares alignment of the humerus and motion of the elbow after functional brace or AEC treatment. One-hundred and five consecutive patients with a closed, extra-articular fracture of the distal humeral diaphysis were identified in the orthopedic trauma databases of 3 hospitals between 2003 and 2012. Seventy-five patients with a follow-up of at least 6 months or with radiographic and clinical evidence of fracture union were included (51 treated with functional bracing and 24 treated with an AEC). All of the fractures healed. The average arc of elbow flexion was 130° ± 9° in braced patients vs 127° ± 12° in casted patients. Four patients (8%) in the bracing group and 4 (17%) in the casting group lost >20° of elbow motion. The average varus angulation on radiographs was 17° ± 8° in braced and 13° ± 8° in casted patients, while the average posterior angulation was 9° ± 6° vs 7° ± 7°, respectively. Closed extra-articular distal diaphyseal humerus fractures heal with both bracing and casting and there are no differences in average elbow motion or radiographic alignment.

BACKGROUND:The incidence and injury patterns of open fractures of the proximal ulna are poorly elucidated and little evidence exists to guide management.QUESTIONS/PURPOSES:The purpose of this study was to compare the (1) bony injury patterns; (2) range of motion (ROM) and frequency of union; and (3) postoperative complications between open and closed fractures of the proximal ulna.METHODS:Seventy-nine consecutive open fractures of the proximal ulna were identified. After excluding fracture-dislocations, penetrating injuries, and pediatric injuries, 60 were compared in a retrospective case-control study with an age- and sex-matched group of 91 closed fractures to compare the bony injury patterns based on radiographic review. In a subset of 39 open and 39 closed fractures with sufficient followup, chart and radiographic review was performed by someone other than the operating surgeon to compare differences in final ROM, union, and postoperative complication rates at a minimum followup of 3 months (mean, 22 and 15 months; range, 3-86 months and 3-51 months for open and closed fractures, respectively). A total of 12% of the fractures were open (79 of 671) at the three study centers, and the majority of fractures were intraarticular (45 of 60 [75%]) with Gustilo-Anderson Type I and II wounds (54 of 60 [90%]).RESULTS:Overall, open fractures of the proximal ulna overall did not have more complex bony injury patterns, but there were more anterior olecranon fracture-dislocations among the open fracture group (nine of 60 [15%] versus two of 91 [2%]; p = 0.004) and more posterior olecranon fracture-dislocations in the closed fracture group (31 of 91 [34%] versus seven of 60 [12%]; p = 0.002). Final ROM was not different in both groups and all fractures healed. There was no difference in wound infection rate but a higher secondary procedure rate among open fractures of the proximal ulna (39% versus 23%, p = 0.014).CONCLUSIONS:In contrast to open fractures of the distal humerus, open fractures of the proximal ulna present with mild soft tissue injuries and do not have more complex bony injury patterns than closed fractures. Our findings suggest that open fractures of the proximal ulna are the result of tension failure of the skin secondary to the limited soft tissue envelope around the proximal ulna. Open fractures of the proximal ulna should be regarded as relatively mild injuries that are not different in severity and prognosis compared with closed fractures.LEVEL OF EVIDENCE:Level III, therapeutic study.

BACKGROUND:The aims of this study were to (1) estimate the prevalence of clinical depression and posttraumatic stress disorder (PTSD) one to two months (Time 1) and five to eight months (Time 2) after musculoskeletal trauma and (2) determine the cross-sectional and longitudinal relationship of psychological variables (depression, PTSD, catastrophic thinking, and pain anxiety) at Time 1 to musculoskeletal disability and pain intensity at Time 1 and Time 2, after accounting for injury characteristics and demographic variables.METHODS:Patients with one or more fractures that had been treated operatively completed measures of depression, PTSD, pain anxiety, catastrophic thinking, musculoskeletal disability (the Short Musculoskeletal Function Assessment [SMFA]), and pain (the Numerical Rating Scale) at rest and during activity at Time 1 (152 patients) and at Time 2 (136 patients). Additional explanatory variables included injury severity, use of opioid pain medication at Time 1, and multiple or single injuries.RESULTS:The screening criteria for an estimated diagnosis of clinical depression were met by thirty-five of the 152 patients at Time 1, and twenty-nine of the 136 patients at Time 2. Screening criteria for an estimated diagnosis of PTSD were met by forty-three of the 152 patients at Time 1 and twenty-five of the 136 patients at Time 2. Cross-sectional hierarchical linear regression models that included multiple injuries, scores of the Abbreviated Injury Scale, and self-reported opioid use explained between 24% and 29% of the variance in pain and disability, respectively, at Time 1. After the addition of psychological variables, the model explained between 49% and 55% of the variance. Catastrophic thinking (as measured with use of the Pain Catastrophizing Scale) at Time 1 was the sole significant predictor of pain at rest, pain during activity, and disability (as measured with use of the SMFA) at Time 2.CONCLUSIONS:We found that psychological factors that are responsive to cognitive behavioral therapy--catastrophic thinking, in particular--are strongly associated with pain intensity and disability in patients recovering from musculoskeletal trauma.

Using inaccurate quotations can propagate misleading information, which might affect the management of patients. The aim of this study was to determine the predictors of quotation inaccuracy in the peer-reviewed orthopaedic literature related to the scaphoid. We randomly selected 100 papers from ten orthopaedic journals. All references were retrieved in full text when available or otherwise excluded. Two observers independently rated all quotations from the selected papers by comparing the claims made by the authors with the data and expressed opinions of the reference source. A statistical analysis determined which article-related factors were predictors of quotation inaccuracy. The mean total inaccuracy rate of the 3840 verified quotes was 7.6%. There was no correlation between the rate of inaccuracy and the impact factor of the journal. Multivariable analysis identified the journal and the type of study (clinical, biomechanical, methodological, case report or review) as important predictors of the total quotation inaccuracy rate. We concluded that inaccurate quotations in the peer-reviewed orthopaedic literature related to the scaphoid were common and slightly more so for certain journals and certain study types. Authors, reviewers and editorial staff play an important role in reducing this inaccuracy.

Purpose The aim of this prospective randomized trial was to test the null hypothesis that there was no difference in the percentage of the fracture line of scaphoid waist fractures that demonstrated bridging bone on computed tomography (CT) 10 weeks after injury between patients treated in a below-elbow cast including or excluding the thumb.Methods A total of 62 patients with a CT or magnetic resonance image confirmed non-displaced or minimally displaced fracture of the scaphoid were enrolled in a prospective, multicenter, randomized trial comparing treatment in a below-elbow cast including or excluding the thumb. There were 55 waist and 7 distal fractures (owing to a miscommunication at 3 of the centers). We adhered to intention-to-treat principles. The primary outcome was the extent of union on CT performed after 10 weeks of cast treatment, expressed as a percentage of the fracture line that had bridging bone, determined by musculoskeletal radiologists blinded to treatment. Secondary study outcomes included wrist motion; grip strength; the Mayo Modified Wrist Score; the Disabilities of the Arm, Shoulder and Hand score; a visual analog scale for pain; and radiographic union at 6 months after injury.Results There was a significant difference in the average extent of union on CT at 10 weeks (85% vs 70%) favoring treatment with a cast excluding the thumb. The overall union rate was 98%. The 1 exception was a patient in the thumb immobilization group who elected operative treatment 1 week after enrollment, used crutches, and failed to heal. There were no significant differences between groups for wrist motion; grip strength; Mayo Modified Wrist Score; Disabilities of the Arm, Shoulder, and Hand score; or pain intensity.Conclusions Immobilization of the thumb appears unnecessary for CT or magnetic resonance image confirmed nondisplaced or minimally displaced fractures of the waist of the scaphoid.

Background We reviewed our experience with low transcondylar, extra-articular distal humerus fractures to determine the prevalence of extra-articular distal humerus fractures, the percentage that are low transcondylar fractures, and the results of treatment. Material and methods One hundred seventy-four fractures of the distal humerus in adult patients were identified. Patients with at least 1-year of follow-up were evaluated based on the medical record according to the system described by Broberg and Morrey. Results Twenty-six fractures (15%) were extra-articular (AO Type A), 15 involved both the medial and lateral columns (8.6%), nine of which were low transcondylar fractures representing 5% of all fractures and 60% of the extra-articular bicolumnar fractures. Among the nine patients with low transcondylar fractures, two had non-union and three died within 3 months of injury. Among the eight patients with healed fractures after sufficient follow-up, patients with higher extra-articular distal humerus fractures had better motion and function than patients with low transcondylar fractures. Conclusions Transcondylar fractures are the most common type of extra-articular bicolumnar fracture and may be more common than previously recognized. Mortality within 3 months and non-union appear common with this fracture type.

Minimally displaced extra-articular bicolumnar fractures of the distal humerus at the level of the base of the olecranon fossa (sometimes referred to as transcondylar fractures) are uncommon. Good results after both operatieve and non-operative treatment have been described, whereas other studies suggest that these fractures have a high risk to non-union. We describe three patients with non-union after a nondisplaced or minimally displaced low transcondylar (extra-articular) fracture of the distal humerus. Three relatively unique non-union cases are described with the aim of increasing awareness of the potential pitfalls associated with these fractures, suggesting that these fractures merit caution and additional study.
