Delayed Presentation of Unstable Triangular Fibrocartilage Complex Tears Treated with Volar Foveal Ligament Repair.

Hypothesis An open volar surgical approach with suture anchor repair of the foveal ligament and temporary pinning of the distal radioulnar joint (DRUJ) is an effective way to treat DRUJ instability associated with chronic foveal tears of the triangular fibrocartilage complex (TFCC). Methods We retrospectively reviewed nine patients with foveal ligament tears of the TFCC and DRUJ instability who underwent open repair of the TFCC using a volar surgical approach, combined with temporary pinning of the DRUJ for 8 weeks. Pain, instability, arc of motion, and functional outcomes scores were evaluated. Results Mean patient age was 40.5 years (range 16.3-56.2). Average time from injury to surgery was 8.4 months (range 2.9-23.3 months). Average final follow-up was 18.9 months from injury (range 12.0-29.3 months), 10.5 months from surgery (range 3.9-18.6 months), and 8.7 months from pin removal (range 1.7-17.2 months). At final follow-up, all patients demonstrated clinically stable DRUJ. Pain scores diminished significantly from pre to final postoperative visits, with averages of 6.8 (range 4.0-9.0) improving to a mean of 0.70 (range 0.0-2.0), respectively. Average postoperative forearm rotation was 71.1 degrees in supination and 76.1 degrees in pronation (average total arc of motion 147.2 degrees, range 90-160 degrees). Average postoperative wrist motion was 68.8 degrees in flexion and 70.6 degrees in extension (average total arc of motion 139.4 degrees, range 110-160 degrees). No patients developed crepitus, recurrent DRUJ instability, or required revision surgery (subsequent to pin removal). Conclusion Volar suture anchor repair of the foveal ligament of the TFCC with DRUJ pinning led to reliable outcomes within this patient group including a stable DRUJ with improved functional outcomes regarding pain, stability, and range of motion in patients with foveal TFCC tears and associated DRUJ instability. These results compare favorably with dorsal repair of the foveal ligament. Level of Incidence This is a Level IV, therapeutic study.

The outcome of patients with cultured pathogens at time of nonunion surgery.

The purpose of this study is to evaluate incidence, preoperative laboratory markers, and outcomes of patients who positively cultured pathogens (PCP) at time of surgery for long bone fracture nonunion. Two-hundred and eighty-eight patients were enrolled in a trauma study on long bone nonunion. Two-hundred and sixteen of those 288 patients were cultured at the time of fracture nonunion surgery. Laboratory data were collected prior to intervention and infectious laboratory markers ordered on patients suspected for infection. Patients were followed for one year. Wound complications, antibiotic use, healing, function, and re-admission for further surgery were assessed. Cultures returned positive on 59 patients (representing 20.5% of the 288 patient cohort or 27.3% of the 216 patients cultured in the operative suite). More PCP's (47.5%; 28 of 59) developed wound complications, with greater mean antibiotic duration and more frequent returns to the OR averaging 1.3 procedures per patient. Twelve-month follow-up was obtained on 249 of the 288 (86.5%) and PCPs reported globally worse function. Patients who PCP at the time of operative management for long bone nonunion was a prognostic indicator of poorer long-term functional outcomes.

A Comprehensive Return-to-Play Analysis of National Basketball Association Players With Operative Patellar Tendon Tears.

BACKGROUND: Patellar tendon tears impart potentially debilitating sequelae among professional basketball athletes. HYPOTHESIS: Professional basketball athletes with patellar tendon tears have decreased return-to-play performance in seasons after injury compared with preinjury statistics. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patellar tendon tears among National Basketball Association (NBA) athletes from the 1999-2000 to 2014-2015 seasons were identified. Player performance statistics for players who underwent operative patellar tendon repair were compared from 1 season before injury to 1 season after injury and 2 seasons before injury to 2 seasons after injury using the primary outcome of player efficiency rating (PER). Secondary performance outcomes were also analyzed. RESULTS: A total of 13 patellar tendon tears (10 complete, 3 partial) were identified among 12 NBA athletes. Three players (25%) did not return to play in the NBA. No significant differences were found in PER in comparisons of 1 season before and after injury (16.6 ± 1.5 vs 14.3 ± 1.7; P = .20) or in comparisons of 2 seasons before and after injury (15.8 ± 0.8 vs 6.3 ± 2.3; P = .49). Diminished performance outcomes were noted for total minutes played (2598 ± 100 vs 1695 ± 78; P = .01), games played (74.8 ± 1.9 vs 60.5 ± 1.4; P = .04), and minutes per game (34.8 ± 1.5 vs 28.2 ± 1.8; P = .02) in comparisons of 1 season before and after injury. Total minutes played per season (2491 ± 190 vs 799 ± 280; P = .045) decreased in comparisons of 2 seasons before and after injury. CONCLUSION: Patellar tendon tears were not associated with diminished efficiency-adjusted performance, as measured by PER, games played, minutes per game played, points per 36 minutes, and rebounds per 36 minutes. However, decreases in total minutes played were observed following patellar tendon tear. Orthopaedic surgeons may be better prepared to counsel basketball athlete patients with patellar tendon tear given these findings.

Performance Outcomes After Hook of Hamate Fractures in Major League Baseball Players.

CONTEXT: Major League Baseball (MLB) players are at risk of hook of hamate fractures. There is a paucity of data assessing the effect of a hook of hamate fracture on MLB players' future athletic performance. OBJECTIVE: To determine if MLB players who sustain hook of hamate fractures demonstrate decreased performance upon return to competition when compared with their performance before injury and that of their control-matched peers. DESIGN: Retrospective case-control design. SETTING: Retrospective database study. PARTICIPANTS: 18 MLB players who sustained hook of hamate fractures. METHODS: Data for 18 MLB players with hook of hamate fractures incurred over 26 seasons (1989-2014) were obtained from injury reports, press releases, and player profiles ( www.mlb.com and www.baseballreference.com ). Player age, position, number of years in the league, mechanism of injury, and treatment were recorded. Individual season statistics for the 2 seasons immediately prior to injury and the 2 seasons after injury for the main performance variable-Wins Above Replacement-were obtained. Eighteen controls matched by player position, age, and performance statistics were identified. A performance comparison of the cohorts was performed. MAIN OUTCOME MEASURES: Postinjury performance compared with preinjury performance and matched-controls. RESULTS: Mean age at the time of injury was 25.1 years with a mean of 4.4 seasons of MLB experience prior to injury. All injuries were sustained to their nondominant batting hand. All players underwent operative intervention. There was no significant change in Wins Above Replacement or isolated power when preinjury and postinjury performance were compared. When compared with matched-controls, no significant decline in performance in Wins Above Replacement the first season and second season after injury was found. CONCLUSION: MLB players sustaining hook of hamate fractures can reasonably expect to return to their preinjury performance levels following operative treatment.

Clinical Skills and Professionalism: Assessing Orthopaedic Residents With Unannounced Standardized Patients.

OBJECTIVE: We developed a series of orthopedic unannounced standardized patient (USP) encounters for the purpose of objective assessment of residents during clinic encounters. DESIGN: Consecutive case-series. SETTING: NYU-Langone Multi-center Academic University Hospital System. PARTICIPANTS: NYU-Langone/Hospital for Joint Diseases Orthopedic Surgery residents; 48 consecutive residents assessed. METHODS: Four orthopedic cases were developed. USPs presented themselves as patients in outpatient clinics. Residents were evaluated on communication skills (information gathering, relationship development, and education and counseling). USPs globally rated whether they would recommend the resident. RESULTS: Forty-eight USP encounters were completed over a 2-year period. Communication skills items were rated at 51% (±30) "well done." Education and counseling skills were rated as the lowest communication domain at 33% (±33). Residents were globally recommended based on communication skills in 63% of the encounters recommended in 70% of encounters based on both professionalism and medical competence. CONCLUSIONS: The USP program has been useful in assessing residents' clinical skills, interpersonal and communications skills, and professionalism. Use of USP in orthopedic surgery training programs can be an objective means for trainee assessment.

Can preoperative nasal cultures of Staphylococcus aureus predict infectious complications or outcomes following repair of fracture nonunion?

INTRODUCTION: Much has been studied with reference to methicillin resistant Staphylococcus aureus (MRSA) and methicillin sensitive S. aureus (MSSA) colonization and associated outcomes and comorbidities. In the area of Orthopedic surgery, literature predominantly comes from the field of arthroplasty. Little is known about outcomes of fracture and Orthopedic trauma patients in the setting of S. aureus colonization. We believe that MRSA/MSSA colonization in and of itself may be a weak marker for generally poor protoplasm, potentially with complex medical history including previous hospitalization or rehab placement. This milieu of risk factors may or may not contribute to poorer outcomes after fracture and fracture nonunion surgery. The purpose of this study is to determine if nasal swabbing for S. aureus (MRSA or MSSA) carriage can predict operative culture, complications, or outcomes following fracture nonunion surgery. METHODS: Sixty-two consecutive patients undergoing surgery for fracture nonunion were prospectively followed. Data analyses were performed using grouped MRSA and MSSA carriers (Staphylococcus carriers: SC). Outcomes analyzed included time to healing, need for additional surgery, and persistent nonunion. RESULTS: Twenty-six percent of patients (16/62) were identified as MSSA carriers, an additional 6.5% (4/62) carried MRSA. Follow-up of at least 12-months was obtained on 90% (56/62) of patients. White blood cell counts, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) values did not differ between SCs and non-carriers pre-operatively. Carriers were just as likely as non-carriers to culture positively for any pathogen at the time of surgery. Although SC's were three times as likely as non-carriers to grow S. aureus (15% vs. 5%), this difference did not reach statistical significance (p=0.3). Post-operative wound complications, antibiotic use, pain at follow-up and progression to healing did not differ between groups. CONCLUSIONS: Ultimately, pre-operative nasal swabbing for S. aureus is a simple and non-invasive diagnostic tool with prognostic implications in patients undergoing fracture nonunion surgery. This study found that MRSA and MSSA colonized patients with fracture nonunion of long bones do not have an increased association with positive cultures or a predisposition towards greater post-operative infectious complications.

Can Tibial Shaft Fractures Bear Weight After Intramedullary Nailing? A Randomized Controlled Trial.

OBJECTIVE: To examine the potential benefits and risks associated with weight-bearing after intramedullary (IM) nailing of unstable tibial shaft fractures. DESIGN: Randomized controlled trial. SETTING: Two New York State level 1 trauma centers, one level 2 trauma center, and 1 tertiary care orthopaedic hospital in a large urban center in New York City. PATIENTS/PARTICIPANTS: Eighty-eight patients with 90 tibial shaft fractures were enrolled. The following were used as inclusion criteria: (1) skeletally mature adult patients 18 years of age or older, (2) displaced fractures of tibial diaphysis (OTA type 42) treated with operative intervention, and (3) radiographs, including injury, operative, and completion of follow-up. Sixty-eight patients with 70 tibial shaft fractures completed follow-up. INTERVENTION: All patients were treated with locked IM nailing. Patients were randomized to 1 of 2 groups: immediate weight-bearing-as-tolerated (WBAT) or non-weight-bearing for the first 6 postoperative weeks (NWB). MAIN OUTCOME MEASURES: Fracture union or treatment failure/revision surgery. RESULTS: There was no statistical difference in the observed time to union between groups (WBAT = 22.1 ± 11.7 weeks vs. NWB = 21.3 ± 9.9 weeks; P = 0.76). Rates of complications did not statistically differ between groups. No fracture loss of reduction leading to malunion was encountered. Short Musculoskeletal Function Assessment scores for all domains did not statistically differ between groups. CONCLUSIONS: Immediate weight-bearing after IM nailing of tibial shaft fractures is safe and is not associated with an increase in adverse events or complications. Patients should be allowed to bear weight as tolerated after IM nailing of OTA subtype 42-A and 42-B tibial shaft fractures. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Does Brachial Plexus Blockade Result in Improved Pain Scores After Distal Radius Fracture Fixation? A Randomized Trial.

BACKGROUND: Distal radius fractures are very common injuries and surgical treatment for them can be painful. Achieving early pain control may help improve patient satisfaction and improve functional outcomes. Little is known about which anesthesia technique (general anesthesia versus brachial plexus blockade) is most beneficial for pain control after distal radius fixation which could significantly affect patients' postoperative course and experience. QUESTIONS/PURPOSES: We asked: (1) Did patients receiving general anesthesia or brachial plexus blockade have worse pain scores at 2, 12, and 24 hours after surgery? (2) Was there a difference in operative suite time between patients who had general anesthesia or brachial plexus blockade, and was there a difference in recovery room time? (3) Did patients receiving general anesthesia or brachial plexus blockade have higher narcotic use after surgery? (4) Do patients receiving general anesthesia or brachial plexus blockade have higher functional assessment scores after distal radius fracture repair at 6 weeks and 12 weeks after surgery? METHODS: A randomized controlled study was performed between February, 2013 and April, 2014 at a multicenter metropolitan tertiary-care referral center. Patients who presented with acute closed distal radius fractures (Orthopaedic Trauma Association 23A-C) were potentially eligible for inclusion. During the study period, 40 patients with closed, displaced, and unstable distal radius fractures were identified as meeting inclusion criteria and offered enrollment and randomization. Three patients (7.5%), all with concomitant injuries, declined to participate at the time of randomization as did one additional patient (2.5%) who chose not to participate, leaving a final sample of 36 participants. There were no dropouts after randomization, and analyses were performed according to an intention-to-treat model. Patients were randomly assigned to one of two groups, general anesthesia or brachial plexus blockade, and among the 36 patients included, 18 were randomized to each group. Medications administered in the postanesthesia care unit were recorded. Patients were discharged receiving oxycodone and acetaminophen 5/325 mg for pain control, and VAS forms were provided. Patients were called at predetermined intervals postoperatively (2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, and 72 hours) to gather pain scores, using the VAS, and to document the doses of analgesics consumed. In addition, patients had regular followups at 2 weeks, 6 weeks, and 12 weeks. Pain scores were again recorded using the VAS at these visits. RESULTS: Patients who received general anesthesia had worse pain scores at 2 hours postoperatively (general anesthesia 6.7 ± 2.3 vs brachial plexus blockade 1.4 ± 2.3; mean difference, 5.381; 95% CI, 3.850-6.913; p < 0.001); whereas reported pain was worse for patients who received a brachial plexus blockade at 12 hours (general anesthesia 3.8 ± 1.9 vs brachial plexus blockade 6.3 ± 2.4; mean difference, -2.535; 95% CI, -4.028 to -1.040; p = 0.002) and 24 hours (general anesthesia 3.8 ± 2.2 vs brachial plexus blockade 5.3 ± 2.5; mean difference, -1.492; 95% CI, -3.105 to 0.120; p = 0.031).There was no difference in operative suite time (general anesthesia 119 ± 16 minutes vs brachial plexus blockade 125 ± 23 minutes; p = 0.432), but time in the recovery room was greater for patients who received general anesthesia (284 ± 137 minutes vs 197 ± 90; p = 0.0398). Patients who received general anesthesia consumed more fentanyl (64 µg ± 93 µg vs 6.9 µg ± 14 µg; p < 0.001) and morphine (2.9 µg ± 3.6 µg vs 0.0 µg; p < 0.001) than patients who received brachial plexus blockade. Functional outcome scores did not differ at 6 weeks (data, with mean and SD for both groups, and p value) or 12 weeks postoperatively (data, with mean and SD for both groups, and p value). CONCLUSIONS: Brachial plexus blockade pain control during the immediate perioperative period was not significantly different from that of general anesthesia in patients undergoing operative fixation of distal radius fractures. However, patients who received a brachial plexus blockade experienced an increase in pain between 12 to 24 hours after surgery. Acknowledging "rebound pain" after the use of regional anesthesia coupled with patient counseling regarding early narcotic administration may allow patients to have more effective postoperative pain control. It is important to have a conversation with patients preoperatively about what to expect regarding rebound pain, postoperative pain control, and to advise them about being aggressive with taking pain medication before the waning of regional anesthesia to keep one step ahead in their pain control management. LEVEL OF EVIDENCE: Level 1, therapeutic study.

Sexual Function Is Impaired After Common Orthopaedic Nonpelvic Trauma.

OBJECTIVES: The purpose of this study was to investigate the prevalence and longitudinal improvement of patient reported sexual dysfunction after 5 common nonpelvic orthopaedic traumatic conditions. DESIGN: Retrospective analysis of prospectively collected data. SETTING: Academic Medical Center. PATIENTS/PARTICIPANTS: The functional status of 1324 patients with acute proximal humerus fractures (n = 104), acute distal radius fractures (n = 396), acute tibial plateau fractures (n = 118), acute ankle fractures (n = 434), and chronic long bone fracture nonunions (n = 272) was prospectively assessed at baseline, 3, 6, and 12 months of posttreatment. Patient reported sexual dysfunction, acquired from validated functional outcomes surveys, was compared with overall patient reported functional outcome for each follow-up visit. Men and women were analyzed separately. RESULTS: Sexual dysfunction at the 3-month follow-up was reported in 31% of proximal humerus fracture patients, 32% of distal radius fracture patients, 47% of tibial plateau patients, 11% of ankle fracture patients, and 42% of long bone nonunions. By 1-year follow-up, greater than 80% of patients with all fracture types reported mild or no sexual dysfunction. Women reported a significantly higher degree of sexual dysfunction than men at 6 months (P = 0.003) and 12 months of follow-up (P = 0.031). CONCLUSIONS: After treatment of acute and chronic orthopaedic trauma conditions, a considerable number of patients experience sexual dysfunction, with women reporting more dysfunction than men. The results of this study should allow orthopaedic trauma surgeons to counsel patients regarding expectations of sexual function after traumatic orthopaedic conditions. LEVEL OF EVIDENCE: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Displaced intra-articular fractures involving the volar rim of the distal radius.

PURPOSE: To describe the features of displaced intra-articular fractures confined to the volar rim of the distal radius and compare outcomes after their operative fixation to complete intra-articular and extra-articular fractures treated with operative fixation. METHODS: A total of 627 distal radius fractures were treated over a 6-year period. Twenty-eight patients had volar rim fractures (type 23-B3, as classified by the Orthopaedic Trauma Association [OTA]), all treated with operative reduction and fixation using a volar buttress plate. Clinical outcome information including radiographs, Short Form-36 health survey, and Disabilities of the Arm, Shoulder, and Hand questionnaire were collected at regular postoperative intervals. Patients with volar rim fractures were compared with patients who sustained other types of operatively managed distal radius fractures (OTA types 23-A, 23-B1/B2, and 23-C). RESULTS: The most common type of volar rim fracture consisted of a single large fragment (OTA 23-B3.2; 46%), followed by comminuted fractures (OTA 23-B3.3; 36%). Restoration of radiographic parameters was similar between groups except for an increased volar tilt in volar rim fractures compared with group 23-B1/B2. Active wrist and finger motion improved in all groups except for wrist extension, which was less in the 23-B1/B2 groups. The 23-B1/B2 group had the greatest pain and worst Short Form-36 scores. Disabilities of the Arm, Shoulder, and Hand questionnaire scores were similar and without differences between groups. CONCLUSIONS: Our data suggest that patients with volar rim distal radius fractures can expect a rapid return to function with minimal risk for complications and have outcomes similar to other types of operatively treated distal radius fractures. Further investigation of type 23-B fractures (23-B1/B2) is warranted owing to evidence of diminished outcomes.

Older age does not affect healing time and functional outcomes after fracture nonunion surgery.

INTRODUCTION: Elderly patients are at risk of fracture nonunion, given the potential setting of osteopenia, poorer fracture biology, and comorbid medical conditions. Risk factors predicting fracture nonunion may compromise the success of fracture nonunion surgery. The purpose of this study was to investigate the effect of patient age on clinical and functional outcome following long bone fracture nonunion surgery. MATERIALS AND METHODS: A retrospective analysis of prospectively collected data identified 288 patients (aged 18-91) who were indicated for long bone nonunion surgery. Two-hundred and seventy-two patients satisfied study inclusion criteria and analyses were performed comparing elderly patients aged ≥65 years (n = 48) with patients <65 years (n = 224) for postoperative wound complications, Short Musculoskeletal Functional Assessment (SMFA) functional status, healing, and surgical revision. Regression analyses were performed to look for associations between age, smoking status, and history of previous nonunion surgery with healing and functional outcome. Twelve-month follow-up was obtained on 91.5% (249 of 272) of patients. RESULTS: Despite demographic differences in the aged population, including a predominance of medical comorbidities (P < .01) and osteopenia (P = .02), there was no statistical differences in the healing rate of elderly patients (95.8% vs 95.1%, P = .6) or time to union (6.2 ± 4.1 months vs. 7.2 ± 6.6, P = .3). Rates of postoperative wound complications and surgical revision did not statistically differ. Elderly patients reported similar levels of function up to 12 months after surgery. Regression analyses failed to show any significant association between age and final union or time to union. There was a strong positive association between smoking and history of previous nonunion surgery with time to union. Age was associated (positively) with 12-month SMFA activity score. CONCLUSIONS: Smoking and failure of previous surgical intervention were associated with nonunion surgery outcomes. Patient's age at the time of surgery was not associated with achieving union. Advanced age was generally not associated with poorer nonunion surgery outcomes.

No advantage to rhBMP-2 in addition to autogenous graft for fracture nonunion.

Bone morphogenetic proteins are a necessary component of the fracture healing cascade. Few studies have delineated the efficacy of iliac crest bone graft and recombinant human bone morphogenetic protein 2 (rhBMP-2), especially, in comparison with the gold standard treatment of nonunion, which is autogenous bone graft alone. This study compared the outcome of patients with fracture nonunion treated with autogenous bone graft plus rhBMP-2 adjuvant vs patients treated with autogenous bone graft alone. A total of 118 consecutive patients who were to undergo long bone nonunion surgery with autogenous bone graft (50) or autogenous bone graft plus rhBMP-2 (68) were identified. Surgical intervention included either harvested iliac autogenous bone graft or autogenous bone graft plus 1.5 mg/mL of rhBMP-2 placed in and around the site of nonunion. No differences were found in the distribution of nonunion sites included within each group. Twelve-month follow-up was obtained on 100 of 118 patients (84.7%). Analyses of demographic characteristics (including tobacco), medical comorbidities, previous surgeries, and nonunion type (atrophic vs hypertrophic) did not differ. Postoperative complication rates did not differ. The percentage of patients who progressed to union did not differ. Mean time to union in the autogenous bone graft plus rhBMP-2 group was 6.6 months (±3.9) vs 5.4 (±2.7) months in the autogenous bone graft-only group (P=.06). Rates of revision (16.2% for rhBMP-2 plus autogenous bone graft vs 8% for autogenous bone graft) did not differ statistically (P=.19), nor did 12-month scores of pain and functional assessment. Although rhBMP-2 is a safe adjuvant, there was no benefit seen when rhBMP-2 was added to autogenous bone graft in the treatment of long bone nonunion. Given its high cost, rhBMP-2 should be reconsidered as an aid to autogenous bone graft in the treatment of nonunion.

Symptomatic atypical femoral fractures are related to underlying hip geometry.

The benefits of bisphosphonates are well documented, but prolonged use has been associated with atypical femur fractures. Radiographic markers for fracture predisposition could potentially aid in safer medication use. In this case-control designed study, we compared hip radiographic parameters and the demographic characteristics of chronic bisphosphonate users who sustained an atypical femoral fracture with a group of chronic bisphosphonate users who did not sustain an atypical femur fracture and also a group who sustained an intertrochanteric hip fracture. Radiographic parameters included were neck-shaft angle (NSA), hip-axis length (HAL) and center-edge angle (CE). Multivariate regression was used to evaluate the relationship between radiographic measures and femur fracture. Receiver-operating characteristic analysis determined cut-off points for neck-shaft angle and risk of atypical femur fracture. Ultimately, pre-fracture radiographs of 53 bisphosphonate users who developed atypical fracture were compared with 43 asymptomatic chronic bisphosphonate users and 64 intertrochanteric fracture patients. Duration of bisphosphonate use did not statistically differ between users sustaining atypical fracture and those without fracture (7.9 [±3.5] vs. 7.7 [±3.3] years, p=0.7). Bisphosphonate users who fractured had acute/varus pre-fracture neck-shaft angles (p<0.001), shorter hip-axis length (p<0.01), and narrower center-edge angles (p<0.01). Regression analysis revealed associations between neck-shaft angle (OR=0.89 [95% CI=0.81-0.97; p=0.01), center edge angle (OR=0.89 [95% CI=0.80-0.99]; p=0.03), and BMI (OR=1.15 [95% CI=1.02-1.31; p=0.03) with fracture development. ROC curve analysis (AUC=0.67 [95% CI=0.56-0.79]) determined that a cut-off point for neck-shaft angle <128.3° yielded 69% sensitivity and 63% specificity for development of atypical femoral fracture. Ultimately, an acute/varus angle of the femoral neck, high BMI, and narrow center-edge angle were associated with development of atypical femur fracture in long-term bisphosphonate users. Patients on long-term bisphosphonates should be regularly radiographically evaluated in order to assess for potential risk of atypical fracture.

Growing up in the shadow of Chornobyl: adolescents' risk perceptions and mental health.

PURPOSE: Despite long-term research on risk perceptions of adults after ecological disasters, little is known about the legacy for the generation exposed to toxic elements as infants. This study examined Chornobyl-related risk perceptions and their relationship to mental health in adolescents raised in Kyiv in the aftermath of the accident. METHODS: Risk perceptions, 12-month DSM-IV major depression (MDD)/generalized anxiety disorder (GAD), and current symptomatology were examined in 265 evacuee adolescents, 261 classmate controls, and 327 population-based controls 19 years after the accident. Competing risk factors, including maternal risk perceptions and MDD/GAD, were taken into account. RESULTS: Significantly more evacuees (48.7%) than controls (33.4-40.0%) reported at least one negative perception of Chornobyl; 18.1% of evacuees versus 10.0-12.8% of controls reported 2-4. In contrast, 75.7% of evacuee mothers versus 34.8-37.6% of controls endorsed 2-4 negative perceptions. In the unadjusted analyses, adolescents' perceptions were associated with both MDD/GAD and symptomatology. After adjusting for competing risk factors, their perceptions were associated with symptomatology only (p < 0.01). Among the competing risk factors, gender, self-esteem, life events, and peer support were significantly associated with MDD/GAD. These measures, along with quality of parental communication, father belligerence when drunk, and maternal MDD/GAD, were significantly associated with symptoms. CONCLUSIONS: More evacuee teens reported negative risk perceptions than controls, but these perceptions were only modestly associated with mental health. Instead, the strongest risk factors comported with epidemiologic studies conducted in other parts of the world. Research is needed to determine whether children raised in the aftermath of other ecological disasters demonstrate similar resilience.

Subjective health legacy of the Chornobyl accident: a comparative study of 19-year olds in Kyiv.

BACKGROUND: Since the Chornobyl accident in 1986, the physical health of exposed children in Ukraine has been monitored, but their perceived health has not been studied. This study examines health perceptions of Ukrainian adolescents exposed to radioactive fallout in utero or as infants, and the epidemiologic and Chornobyl-related influences on self-reported health. METHOD: We assessed three groups of 19-year olds in Kyiv: 262 evacuees from contaminated areas near the plant; 261 classmate controls; and 325 population-based controls. The evacuees and classmates were previously assessed at age 11. Structured interviews were conducted with the adolescents and their mothers (N = 766), followed by general physical examinations (N = 722) and blood tests (N = 707). Proportional odds logistic regression and multi-group path analysis were the major statistical tests. RESULTS: The examination and blood test results were similar across groups except for a significantly elevated rate of thyroid enlargement found by palpation in evacuees (17.8%) compared former classmates (8.7%) and population-based controls (8.0%). In addition, four evacuees and one population control had had a thyroidectomy. Compared to controls, the evacuees rated their health the least positively and reported more medically diagnosed illnesses during the 5 years preceding the interview, particularly thyroid disease, migraine headache, and vascular dystony. The consistent risk factors (p < 0.001) for these subjective health reports were evacuee status, female gender, multiple hospitalizations, and health risk perception regarding Chornobyl. All three groups of mothers rated their children's health more negatively than the adolescents themselves, and maternal ratings were uniquely associated with the adolescents' health reports in the adjusted models. In the longitudinal evacuee and classmate subsamples, path analysis showed that mothers' health ratings when the children were age 11 predicted their later evaluations which in turn were associated with the adolescent self-reports. CONCLUSION: The more negative self-evaluations of the evacuees were linked to a number of risk factors, including multiple hospitalizations, health risk perceptions, and epidemiologic risk factors. The increased rate of thyroid cancer and other diagnoses no doubt contributed to the evacuees' less positive subjective health. The strong effect of the mothers' perceptions argues in favor of developing risk communication programs for families rather than for mothers or adolescents as separate target groups.
