Background: Patients experiencing acute trauma have limited time for their involvement in shared decision making, which may lead to decisional conflict. The purpose of this study was to evaluate whether providing audiovisual surgical information can reduce decisional conflict when deciding between surgical and nonsurgical treatment in patients with distal radius fractures (DRFs) and to evaluate factors that may affect decisional conflict. Methods: We prospectively enrolled 50 consecutive patients who presented with acute DRFs and chose to undergo surgery, for which volar plate fixation was recommended. We randomized these patients into 2 groups. The test group was given a video clip of audiovisual surgical information in addition to regular information while the control group was only given regular information. The video clip consisted of the purpose, procedure, and effect of the surgery, precautions and complications after the operation, and other treatment options that could be performed if operation was not performed. At 2 weeks after the surgery, we evaluated patients’ decisional conflict using a decisional conflict scale (DCS). In addition, we evaluated factors that might affect decisional conflict, such as age, dominant hand, comorbidities, history of previous operations, perceived disability, and provision of the video clip. Results: The test group showed significantly lower DCS scores than the control group (19.6 vs. 32.1, p = 0.001). In multivariate analysis, younger age and provision of the video clip were associated with lower DCS scores. Conclusions This study has demonstrated that providing information through audiovisual media such as video clips could reduce decisional conflict in patients who chose to undergo plate fixation for DRFs. This study also suggests that older patients may need more careful doctor-patient communication as they have more decisional conflict than younger patients.

Ulnar impaction syndrome is one of the common causes of ulnar-sided wrist pain. The pain is usually aggravated by ulnar deviation during a power grip, especially when the forearm is in a pronated position. The most common predisposing factor of ulnar impaction syndrome is ulnar positive variance, which is an increased ulnar length relative to the radius of the radiocarpal joint. However, it can also occur in patients with ulnar neutral or negative variance because ulnar variance can increase during functional activities, including pronation and power gripping. In these patients, the triangular fibrocartilage complex (TFCC) may be thickened. If conservative treatments—lifestyle modification, medication, or wrist splinting—are unsuccessful, surgical treatments, such as wafer procedure or ulnar shortening osteotomy can be considered. The wafer procedure is an effective treatment for ulnar impaction syndrome. It removes the distal 2 to 4 mm of the ulnar head, while preserving the ulnar styloid process from fracturing via a limited open or an arthroscopic approach. The advantages of the wafer procedure are that it does not require bone healing or internal fixation and provides direct access to TFCC. However, it is a technically demanding procedure and is contraindicated in patients with distal radio-ulnar joint (DRUJ) instability, lunotriquetral instability, ulnar minus variance, and with an ulnar positive variance of more than 4 mm. Ulnar shortening osteotomy is the most popular method for the treatment of ulnar impaction syndrome. It can effectively relieve ulnar impaction symptoms and stabilize DRUJ. However, an excessive amount of shortening may increase the peak pressure at DRUJ, which results in DRUJ arthritis. There is also a possibility of delayed union or nonunion in the osteotomy site. To prevent delayed union or nonunion, we should make an effort to decrease the gap in the osteotomy site during surgery. A serial follow-up is also recommended to evaluate the occurrence of arthritis in DRUJ after ulnar shortening.

Background: Treating osteoporosis in patients with a distal radius fracture (DRF) became paramount at the Fracture Liaison Service. Spinal sagittal imbalance emerged as a risk factor for subsequent fractures. Therefore, here we investigated the spinal profile of patients with DRF to investigate its association with a history of falls and prevalent vertebral fractures. Methods: We reviewed the cases of 162 women presenting with DRF and 162 age-matched women without fracture who underwent an osteoporosis evaluation including bone mineral density (BMD) and lateral spine imaging. We compared the incidence of prevalent vertebral fracture and sagittal vertical axis (SVA) to measure spinal sagittal imbalance. We also performed a regression analysis of the risks of prevalent vertebral fracture, such as age, body mass index (BMI), BMD, and SVA. Results: The SVA was significantly smaller (indicating more stable sagittal balance) in patients with a DRF versus controls (16 mm vs. 34 mm, respectively; p<0.001). The incidence of a prevalent vertebral fracture was similar between groups (12% vs. 15%, respectively; p=0.332). In both groups, the SVA was significantly greater in those with versus without a vertebral fracture. The vertebral fracture was significantly associated with age and SVA but not BMI or spinal BMD. Conclusions Spinal sagittal balance was superior in DRF patients, yet the frequency of prevalent vertebral fractures was similar. The identification of this unique spinal profile in patients with DRF may increase our understanding of osteoporotic fractures.

Orthopedic surgeons treating fractures need to consider comorbidities, including chronic kidney disease (CKD), which affects millions worldwide. CKD patients are at elevated risk of fractures due to osteoporosis, especially in advanced stages. In addition, fractures in CKD patients pose challenges due to impaired bone healing and increased post-fracture complications including surgical site infection and nonunion. In this article, we will discuss factors that must be considered when treating fractures in CKD patients.Perioperative management includes careful adjustment of hemodialysis schedules, selection of anesthetic methods, and addressing bleeding tendencies. Tourniquet usage for fractures in limbs with arteriovenous fistulae should be cautious. Pain medication should be administered carefully, with opioids like hydromorphone preferred over nonsteroidal anti-inflammatory drugs. Medical management after fractures should address underlying factors and include physical rehabilitation to reduce the risk of subsequent fractures. A comprehensive approach to fracture management in CKD patients can improve outcomes.

Measurements of ovarian reserve play an important role in predicting the clinical results of assisted reproductive technology (ART). The ideal markers of ovarian reserve for clinical applications should have high specificity in order to determine genuine poor responders. Basal follicle-stimulating hormone levels, antral follicle count, and serum anti-Müllerian hormone (AMH) levels have been suggested as ovarian reserve tests that may fulfill this requirement, with serum AMH levels being the most promising parameter. Serum AMH levels have been suggested to be a predictor of clinical pregnancy in ART for older women, who are at a high risk for decreased ovarian response. We reviewed the prognostic significance of ovarian reserve tests for patients undergoing ART treatment, with a particular focus on the significance of serum AMH levels in patients at a high risk of poor ovarian response.

OBJECTIVES: The purpose of this study is to compare ultimate tensile load of newly designed loop suture technique, to those of Pulvertaft fishmouth suture technique and Kessler suture technique with core strands. MATERIALS AND METHODS: Eight week-old Habbard chickens were sacrificed to harvest flexor digitorum logus tendon of long toe. They were divided into four groups according to suture technique; interweave suture group, loop suture group, Kessler suture group, and normal control group. Twenty tendons were tested in each group. Comparison of cross-sectional areas between each technique was verified by statistical method and the difference was not statistically significant (p>0.05). Tensile load and deformed length were checked by Instron (Model 1000, Instron Corp, Canton, MA). ANOVA test was used for statistical analysis. RESULTS: Ultimate tensile loads were 22.83+/-7.89 N in interweave suture group, 30.58+/-5.96 N in loop suture group, and 10.83+/-4.47 N in Kessler suture group. These results showed statistically significant differences (p<0.001). The values were 33 % in interweave suture, 44% in loop suture, and 15 % in Kessler's suture respectively. Absorbed energy were 0.48+/-0.32 J in interweave suture group, 0.61+/-0.18 J in loop suture group, and 0.22+/-0.15 J in Kessler suture group, and 1.01+/-0.20 J in normal control group. There were statisti - cally significant differences between each groups (p<0.01). CONCLUSION: The loop suture technique showed better biomechanical properties than interweave or Kessler technique. We think the loop suture technique is a simple and useful method, especially for tendon transfer or tendon graft when tendon length is sufficiently long to make a good tendon overlap.

PURPOSE: To present the procedure and results of dorsal wedge osteotomy fixated by bioabsorbable polyglycolide pins for the treatment of symptomatic Freiberg's disease. MATERIALS AND METHODS: From January 1997 to December 2002, six patients with Freiberg's disease underwent dorsal wedge osteotomy of the metatarsal neck to bring the healthy plantar part of the metatarsal head into articulation. Bioabsorbable polyglycolide pins were used for the fixation and short-leg walking cast was applied for 4 weeks. RESULTS: All patients returned to full daily activities without pain in three months after the operation. Radiographically, solid healing of the osteotomy was observed at average ten weeks. The active range of motion of the metatarsophalangeal joint increased by a mean gain of 30 degrees, and no complication such as displacement, osteolysis or sinus formation was observed. CONCLUSION: Dorsal wedge osteotomy fixated by bioabsorbable pins for patients with symptomatic Freiberg's disease is effective procedure that provides relatively early range of motion exercise and avoids second procedure for implant removal.

BACKGROUND: To determine whether olecranon fractures have osteoporotic features such as age-dependent, low bone attenuation and low-energy trauma as a cause of injury. METHODS: Elbow computed tomography (CT) and medical record review were performed in 114 patients (53 males and 61 females) with acute olecranon fractures. The mean age was 57 years. Bone attenuation was measured on the central part of the olecranon on sagittal CT images avoiding the fracture, and on the distal humerus (distal metaphysis and medial and lateral condyles) on coronal CT images. We compared bone attenuation and causes of injury (high or low energy trauma) between younger (<50 years) and older (≥50 years) patients in each gender. Multiple regression analysis was performed to determine the effect of age and gender on bone attenuation. RESULTS: Mean bone attenuation in older male and female patients was significantly lower than in younger patients, except at the medial condyle in men. The proportion of low-energy trauma in older male patients was significantly higher than in younger male patients. In female patients, low-energy trauma was predominant in both younger and older patients. Age and female gender had significantly negative effects on bone attenuation. CONCLUSIONS: This study demonstrated that olecranon fractures have osteoporotic features, including age-dependent low bone attenuation and low-energy trauma as the predominant cause of injury. Our results suggest that osteoporosis evaluation should be considered for patients aged 50 years or more with olecranon fractures.
