Bilateral Lesser Tuberosity Fractures: Technique and a Case Report with Literature Review.

Isolated lesser tuberosity fractures are a rare subset of proximal humerus fractures and are often associated with seizures. Displaced fractures can lead to chronic pain, reduced shoulder function, and posterior instability. Operative treatment is frequently recommended with the displacement of more than 5 mm or angulation of more than 45 degrees. We report on a 31-year-old man with bilateral lesser tuberosity fractures who underwent operative fixation for 1 fracture and nonoperative fixation for the other.

A Systematic Review of the Management of Upper Extremity Orthopaedic Injuries in Epileptic Patients.

Background: During seizures, injury of the upper extremities may occur. Standardized guidelines are deficient for diagnosis and perioperative care. Methods: PubMed, Embase, Cochrane, Scopus, and Web of Science databases were systematically screened using predefined search terms. Results: Of the 59 patients included, 36 (61.0%) involved a posterior shoulder dislocation. Associated fractures were observed in 34 (57.6%) cases with surgical procedures performed in 30 (50.8%) patients. Functional outcomes were reported in 44 patients, with over half (23 of 44, [52.2%]) endorsing range of motion deficits. Conclusion: Standardized guidelines, to guarantee timely management of injury in post-seizure patients, are needed with a customized treatment approach that accommodates the various aspects of their condition.

Management of lower extremity orthopaedic injuries in epileptic patients: A systematic review.

Lower-extremity injuries may occur during seizures. There is a lack of standardized guidelines when diagnosing and planning perioperative care. Databases were systematically screened using predefined search terms. Of the 13 patients included, seven (53.8%) involved bilateral femoral neck fractures. Associated fractures were observed in all cases with surgical intervention performed in eight (61.5%) patients. Eleven patients reported functional outcomes, with over a quarter (three of 11, [27.3%]) endorsing mild range of motion deficits or issues with ambulation. Post-seizure patients may require standardized diagnostic protocols to ensure prompt management with a specialized treatment approach that accommodates the nuances of their condition.

Ankle Fracture Epidemiology in the United States: Patient-Related Trends and Mechanisms of Injury.

Current nationwide epidemiological data regarding ankle fractures are scarce. Such information is important towards better quantifying the mortality associated with such injuries, financial impact, as well as the implementation of preventative measures. This study evaluated the epidemiology of ankle fractures that occurred during a 5-year period. Specifically, we evaluated demographics, mechanism of injury, and disposition. The National Electronic Injury Surveillance System was queried to identify all patients with ankle fractures that presented to US hospital emergency departments between 2012 and 2016. Census data were used to determine the incidence rates of ankle fractures in terms of age, sex, and race. There was an estimated total of 673,214 ankle fractures that occurred during this period, with an incidence rate of 4.22/10,000 person-years. The mean age of patients with an ankle fracture was 37 ± 22.86 (SD) years; 23.5% of ankle fractures occurred in patients aged 10 to 19 years (7.56/10,000 person-years). In addition, 44% of ankle fractures occurred in men (3.81/10,000 person-years), whereas 56% occurred in women (4.63/10,000 person-years). Data on race/ethnicity were available for 71% of the subjects, with incidence rates of 2.85/10,000 person-years for whites, 3.01/10,000 person-years for blacks, and 4.08/10,000 person-years for others. The most common mechanism of injury was falls (54.83%), followed by sports (20.76%), exercise (16.84%), jumping (4.42%), trauma (2.84%), and other (0.30%). For disposition, 81.84% of patients were treated and released, 1.43% were transferred, 16.01% were admitted, 0.59% were held for observation, and 0.13% left against medical advice. The highest incidence of ankle fractures in men occurred in the 10-to-19-years age group, but women were more commonly affected in all other age groups.

Are inferior facetectomies adequate and suitable for surgical treatment of adolescent idiopathic scoliosis?

STUDY DESIGN: Retrospective review. BACKGROUND: Inferior facetectomies, with the utilization of segmental pedicle screw constructs for corrective fixation, can provide adequate flexibility and post less risk of neural tissue and blood loss. We analyzed outcomes of surgical treatment for adolescent idiopathic scoliosis (AIS) using inferior facetectomies and segmental pedicle screw constructs. We hypothesized that adequate main curve correction and suitable surgical outcomes would be observed using this technique. METHODS: We reviewed 38 AIS patients who underwent inferior facetectomies and segmental pedicle screw constructs by 2 surgeons at a single institution between May 2014 and December 2016. Coronal and sagittal radiographic measurements were evaluated over 1-year follow-up by 2 trained observers not associated with the surgeries. Surgical details, complications, and hospital length of stay (LOS) were also recorded. RESULTS: Mean fusion levels were 11.0 ±â€Š1.7. The mean Cobb angle of main AIS curves improved from 48.6±â€Š10.1 degree preoperatively to 11.8±â€Š6.2 degree postoperatively and 12.4±â€Š6.2 degree at 1-year follow-up, which percentage correction was 75.9% and 74.6%, respectively. The mean thoracic kyphosis (T5-12) angle was 20.7±â€Š11.6 degree preoperatively, 17.4±â€Š8.0 degree postoperatively, and 16.8±â€Š8.4 degree at 1-year follow-up. The mean surgical time, estimated blood loss, and LOS were 232.4 ±â€Š35.7 minutes, 475.0 ±â€Š169.6 mL, and 3.5 ±â€Š1.3 days. Twelve patients received blood transfusion. There were no neurological or wound complications. CONCLUSIONS: This case series demonstrated adequate correction of main AIS curves, acceptable thoracic kyphosis and blood loss, and short surgical time and LOS in AIS patients treated with inferior facetectomies and segmental pedicle screw constructs, potentially indicating that inferior facetectomies are adequate and suitable for AIS surgery when segmental pedicle screw constructs are utilized.

Survivorship and complications of total hip arthroplasty in patients with dwarfism.

BACKGROUND: Total hip arthroplasty (THA) is a common procedure used to treat bony hip deformities and skeletal dysplasia in dwarfism. These surgeries are often more difficult than conventional THA as they may involve malformed joints and poor bone quality, and may require smaller prostheses. This study aims to investigate whether implant survivorship and revision rates vary among patients with and without dwarfism undergoing THA. METHODS: A retrospective case-control study was performed for 102 THAs completed between 1997 and 2014 in patients under the height threshold of 147.32 cm. This cohort was matched 1:1.5 with patients of normal height with respect to age, gender, year of surgery, and Charlson comorbidities. All cases had a minimum follow-up of 1 year. A chart review was performed to identify patient and surgical characteristics, including outcomes. Radiographs were assessed for deformity, loosening, and periprosthetic fractures among other factors. RESULTS: The 2-, 5-, and 10-year survivorship of THA in patients with dwarfism was 92.9%, 92.9%, and 80.7%, respectively; and 94.4%, 86.4%, and 86.4% for controls, respectively (p = 0.95). The dwarfism cohort demonstrated an OR of 3.81 and 3.02 for revision for periprosthetic fractures (p = 0.11) and mechanical wear (p = 0.21), respectively. CONCLUSIONS: THA in patients with dwarfism achieves comparable results to a non-dwarfism population with regards to implant survivorship; however, there is a trend toward increased periprosthetic fractures and wear-related failures. Surgeons should be aware of this potentially higher risk in this population and take morphological differences into account during surgical planning and technique.

A Current Procedural Terminology Code for "Knee Conversion" Is Needed to Account for the Additional Surgical Time Required Compared to Total Knee Arthroplasty.

BACKGROUND: Previous knee injury requiring surgical intervention increases the rate of future arthroplasty. Coding modifiers for removal of previous hardware or increased complexity offer inconsistent results. A Current Procedural Terminology code for knee conversion does not currently exist as it does for conversion hip arthroplasty. We investigate the extra time associated with conversion knee arthroplasty. METHODS: Sixty-three total knee arthroplasty (TKA) cases in the setting of previous knee hardware were identified from our institution between 2008 and 2015. Knee conversions were matched to primary TKA by age, gender, body mass index, Charlson Comorbidity Index, and surgeon, in a 3:1 ratio. Patients who underwent knee conversions were compared to matched TKA with regard to operative time, length of stay, discharge destination, readmission, and repeat procedures within 90 days from index procedure. RESULTS: The mean operating room time for primary TKA was 71.7 minutes (range 36-138). The mean operating room time for knee conversion was significantly greater by an additional 31 minutes; mean 102.1 minutes (range 56-256 minutes, P < .0001). Rates of readmission, 0.5% vs 3.2%, and repeat procedures, 5.3% vs 12.7%, within 90 days were greater for knee conversions. There was no difference in length of stay or discharge destination. CONCLUSION: Total knee conversion results in a 43% increase in operative time and more than twice the rate of readmission and repeat procedures within 90 days compared to TKA. This suggests the need for an additional Current Procedural Terminology code for knee conversion arthroplasty to compensate surgeons for the extra time required for conversions.
