The Prevalence of Hip Dysplasia on Radiographs for Adolescent Idiopathic Scoliosis.

BACKGROUND: During radiographic assessment of adolescent idiopathic scoliosis (AIS), upright images frequently capture the hip. The purpose of this study was to assess the prevalence of radiographic hip dysplasia on postero-anterior (PA) scoliosis radiographs, as defined as a lateral center edge angle (LCEA) ≤25 degrees. METHODS: All patients with upright PA scoliosis radiographs over a one-year study period at a single tertiary academic medical center (2020 to 2021) were included in the study. Radiographs containing the hip joints were annotated by 3 reviewers for left and right LCEA, and triradiate cartilage (TRC) status. Inter-rater reliability was determined among the 3 reviewers. RESULTS: Two hundred fifty patients {500 hips, 75.6% female, median age 14 [interquartile range (IQR)=3]} had PA scoliosis radiographs that captured the hip, which qualified for analysis. Seventy-four hips (14.8%) demonstrated evidence of dysplasia (LCEA ≤25 deg) in 55/250 patients (22%). The median LCEA was significantly lower in the dysplastic hip cohort (23.9 deg, IQR=4.8 deg), compared with those without dysplasia (33 deg IQR=7.3 deg; P =0.001). A higher percentage of dysplastic hip patients were female than male (72.7% vs. 27.3%). Patients with bilateral dysplasia had a similar LCEA ( 22.9 deg) [to those with unilateral dysplasia (22.9 deg left, 23.9 deg right, P =0.689)]. CONCLUSIONS: In a cohort of 250 AIS patients, 22% demonstrated evidence of hip dysplasia, as defined as an LCEA ≤2 degrees. The dysplastic patients were more likely to be female. Screening for hip symptomatology in AIS patients may be of benefit, considering the frequency of radiographic hip dysplasia in this population. LEVEL OF EVIDENCE: III. Type of Evidence: diagnostic.

Intradepartmental orthopaedic fragility fracture liaison improves osteoporosis follow-up and treatment.

OBJECTIVE: Over 2 million people in the United States sustain fractures related to osteoporosis annually, but only 20% of these patients receive treatment for their osteoporosis. The purpose of this study was to evaluate the effects of a fragility fracture liaison within the orthopedic department on treatment and follow up for osteoporosis. DESIGN: Retrospective cohort study SETTING: University Level I Trauma center PARTICIPANTS: 112 patients treated under the aegis of an interdepartmental fracture liaison and 208 patients treated following the introduction of an orthopedic fragility fracture liaison at a single institution. INTERVENTION: Transition from referral to interdepartmental fracture liaison to intradepartmental orthopedic fragility fracture liaison for fragility fractures. MAIN OUTCOME MEASURES: Outcomes evaluated included demographics, fracture type, DEXA scan results, follow up and treatment plan, and subsequent fracture. RESULTS: The mean age at time of fracture was 75 years, and the mean BMI was 27. The most common fracture types were femoral neck fractures (29%), pertrochanteric fractures (30%) and femur fractures (8%). There was a statistically significant increase in adherence to follow up and treatment after the introduction of an orthopaedic fragility fracture liaison. CONCLUSIONS: The introduction of an intradepartmental fragility fracture liaison significantly increases osteoporosis follow-up and introduces the ability to combine both osteoporosis treatment and postoperative orthopaedic care. The results of this study highlight the utility of incorporating a fragility fracture liaison within the orthopaedic department given the economic burden of fragility fractures and the morbidity associated with these fractures. LEVEL OF EVIDENCE: III cohort study.

Platelet-Rich Plasma for the Treatment of Low Back Pain: a Comprehensive Review.

PURPOSE OF REVIEW: Back pain is a growing problem worldwide, incurring enormous economic costs and disability. Current treatment modalities often provide adequate relief but fail to address underlying conditions. Regenerative cellular modalities aim to restore anatomical function in degenerative conditions which may cause low back pain. Platelet-rich plasma (PRP) consists of an increased concentration of autologous platelets suspended in a small amount of plasma. PRP can be administered via injection or topically and is prepared using various techniques. RECENT FINDINGS: While a unifying mechanism of action is not well understood, biochemical and cellular changes involved in inflammation and mechanical structure have been detected in both in vitro and in vivo studies. At a higher level, PRP injection research utilizing animal models and patient data have provided insights into pain relief, chondroprotection, and factors that impact the therapy's efficacy. Recently, a small number of studies have promoted PRP injection as a relatively safe means of treating patients with degenerative disc disease who have failed other means of managing their lower back pain. PRP injections for sacroiliac joint-related pain are not an accepted or common treatment modality; the evidence for their efficacy remains to be seen outside of small RCTs and case reports. A small number of prospective trials have suggested there may be some benefit to using PRP injection in the treatment of pain or functional decline caused by facet joint arthropathy. These commonly used modalities require further study to improve quality of evidence and to investigate the safety and efficacy of PRP injections for various common causes of chronic low back.
