Impact of Possible Sarcopenia and Nutritional Status on Postoperative Quick Disabilities of the Arm, Shoulder, and Hand Score in Geriatric Women With Distal Radius Fracture.

PURPOSE: Distal radius fracture (DRF), sarcopenia, and malnutrition have been reported to be interrelated. However, there are few reports on the effects of sarcopenia and malnutrition on DRF patients' postoperative outcomes. This study examined the healthy-side grip strength and preoperative blood tests to determine the presence of possible sarcopenia (PS) and malnutrition in geriatric women with DRF and their impact on postoperative functional outcomes. METHODS: Fifty-five woman older than 60 years treated with volar-locking plate fixation for low-energy DRF from standing-level falls were retrospectively studied. Based on the criteria of The Asian Working Group for Sarcopenia 2019, patients with a healthy-side grip strength <18 kg were defined as PS. Nutritional assessment was performed using Onodera's Prognostic Nutritional Index (PNI) before surgery, with a value <50 defined as malnutrition. The Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) was used for functional assessment at 1 year after surgery. Patients were divided into two groups according to PS, and patient demographic data and postoperative outcomes were compared. Multiple regression analysis was performed to estimate the regression coefficient and 95% confidence intervals for 1-year QuickDASH after surgery with adjustment for age, PS, and malnutrition. RESULTS: Possible sarcopenia was present in 10 patients (18.2%), and malnutrition in 24 patients (43.6%). Possible sarcopenia patients were older, had lower PNI, serum albumin, and both sides grip strength, and worse QuickDASH compared with non-PS patients. In multiple regression analysis, age, PS, and malnutrition were significant predictors of QuickDASH (standardized coefficient ß, 0.35, 0.34, and 0.24; 95% confidence interval, 0.22-1.02, 3.52-16.49, and 0.50-10.78). CONCLUSIONS: Possible sarcopenia with a healthy-side grip strength <18 kg and malnutrition with a PNI <50 were associated with worse 1-year QuickDASH after surgery in women DRF patients over 60 years. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic Ⅳ.

Heparin-Induced Thrombocytopenia After Revascularization of Gustilo-Anderson Type IIIC Open Lower Leg Fracture: A Case Report of Subsequent Ischemic Limb Salvage Failure.

BACKGROUND Heparin-induced thrombocytopenia (HIT) is a disease in which the immune response elicited by heparin results in a state of hypercoagulability and platelet activation, leading to thrombocytopenia and thromboembolism. Gustilo-Anderson type IIIC open fractures of the extremities are defined as open fractures presenting with arterial injuries that require repair and result in treatment challenges and complications. The diagnosis of HIT can be difficult in patients with severe trauma with consumptive thrombocytopenia associated with heavy bleeding and the use of heparin after vascular anastomosis. CASE REPORT A 48-year-old man was injured in a car accident, pinching his right lower leg and sustaining a Gustilo-Anderson type IIIc open fracture, for which he underwent emergency revascularization surgery. Heparin was administered continuously immediately after the surgery. On postoperative day 9, ischemic changes were observed in the right foot, and we performed suture re-anastomosis; however, the blood circulation in the right lower leg did not resume, and right lower leg amputation was performed due to ischemic necrosis with the onset of HIT. Postoperatively, the patient was switched to edoxaban after the recovery of his platelet count. Thereafter, the patient experienced no new thrombus occlusion or wound trouble, and was able to walk on a prosthetic leg and return to daily life. CONCLUSIONS It is important to consider the possibility of HIT as soon as thrombocytopenia appears in patients with Gustilo-Anderson type IIIC open fracture who are receiving heparin after vascular anastomosis, as a delayed diagnosis of HIT can make it difficult to save the limb.

Prevalence and factors associated with lateral epicondylitis among hospital healthcare workers.

Background: Hospital healthcare workers have been reported to have a high prevalence of musculoskeletal disorders, but their association with lateral epicondylitis (LE) is unknown. This study aimed to clarify the prevalence of LE and its associated factors among hospital healthcare workers. Methods: The present study included all staff members of a secondary emergency hospital who provided their consent to participate. Participants with a history of elbow joint trauma were excluded from this study. The diagnostic criteria for definite LE were: (1) pain in the elbow joint within 2 weeks of the study; (2) pain in the lateral epicondyle region on resisted extension of the wrist with the elbow extended; and (3) tenderness in the lateral epicondyle. The diagnosis of LE was defined by meeting all criteria. Age, height, weight, sex, dominant hand, occupation, years of employment, smoking history, drinking history, personal computer usage history, and smartphone usage history were investigated using a questionnaire. A physical examination, in addition to evaluation of pain in the lateral epicondyle, grip strength and wrist extension strength were measured. A statistical analysis was used to assess the prevalence of LE and its associated factors. All investigations, including the diagnosis of LE, were performed by a single orthopedic specialist. Results: We evaluated 544 individuals, corresponding to approximately 80% of all staff members. The median age was 39 years (interquartile range, 30-48). The study population included 154 males and 390 females. The occupations of the participants were as follows: nurses (n = 265), doctors (n = 47), clerks (n = 93), therapists (n = 27), certified care workers (n = 23), medical technologists (n = 22), pharmacists (n = 19), and others (n = 48). LE was diagnosed in 30 limbs/30 individuals with a prevalence of approximately 5.5%. There was no difference in the prevalence of LE among occupations (P = .85). A logistic regression analysis revealed that age (odds ratio, 1.05; 95% confidence interval 1.01-1.1; P = .01) and smoking history (odds ratio, 2.94; 95% confidence interval 1.01-8.56; P = .04) were independently associated with LE. Conclusion: This study was conducted to evaluate the prevalence of LE among hospital healthcare workers. The prevalence of LE was 5.5%, and LE was independently associated with age and smoking history.

Relationship between coordination variability and Osgood-Schlatter disease in male junior youth soccer players -cross-sectional study using an inertial measurement unit.

BACKGROUND: Osgood-Schlatter disease is a common overuse injury, and motor coordination is discussed as a risk factor; however, no reports have examined motor coordination in young soccer players with Osgood-Schlatter disease. This study aimed to investigate the difference in motor coordination between Osgood-Schlatter disease-affected and non-affected soccer players on a junior youth soccer team. METHODS: This cross-sectional study investigated 35 young soccer players of 12-15 years of age, who completed a self-administered questionnaire covering general information, injury history, and athletic experience. An inertial measurement unit was attached to the participant's thoracic spine, lumbar spine, pelvis, thigh, and lower leg. The sagittal plane tilt angle of each body segment during squatting was analyzed. The continuous relative phase was calculated using the sagittal plane tilt angle. The mean absolute relative phase and continuous relative phase variabilities were calculated and compared between Osgood-Schlatter disease-affected and non-affected players. FINDINGS: The sagittal plane tilt angle of each body segment during static standing and maximum flexion did not differ between the two groups. However, the Osgood-Schlatter disease group had significantly less continuous relative phase variability between the lumbar spine and pelvis (P < 0.01, Cohen's d = 0.91). The Osgood-Schlatter disease group had significantly fewer participants with other sports experience (P = 0.032, φ = 0.36). INTERPRETATION: Dysfunctional lower trunk and hip muscles may be leading to Osgood-Schlatter disease. It is suggested that a variety of physical activities should be performed in the junior age group to allow players to acquire a variety of movement patterns.

Total elbow arthroplasty for hemophilic osteoproliferative elbow arthritis with severe flexion contracture: A case report.

Total elbow arthroplasty is effective for pain relief and the functional improvement of severe symptomatic hemophilic osteoproliferative arthropathy. Nevertheless, high complication rates have been reported. This report describes clinical results obtained at 30-month follow-up of total elbow arthroplasty in a hemophilic patient with severe flexion contracture. A 50-year-old patient with advanced left elbow hemophilic arthropathy underwent unlinked total elbow arthroplasty. He had sustained an intraoperative fracture of the medial part of a supracondylar humerus complication. To control perioperative bleeding, strict factor VIII replacement therapy was performed under the guidance of hematologists. The total elbow range of motion was 35° preoperatively, but it had improved to 110° postoperatively. The Patient-Rated Elbow Evaluation Japanese version score, which was 53.7 preoperatively, improved to 10.7 postoperatively. During the 30 months after operation, no complication occurred. Good clinical results have been obtained under close collaboration with hematologists and close patient adherence following treatment.
