Purpose: This study analyzed the prognostic factors in patients with femoral head fractures by comparing two groups with and without complications. Materials and Methods: A retrospective study was performed on femoral head fracture patients who visited two different level-1 trauma centers from January 1, 2014 to June 30, 2018. Thirty-three patients with a follow-up period of more than one year were included. Early complications were defined as fair or poor in the Thompson–Epstein clinical evaluation criteria and grades 3 or 4 in the Kellgren– Lawrence classification within one year after the fracture. The patients were divided into two groups, with and without early complications. Statistical analysis was performed for the nominal variables with a Fisher’s exact test and continuous variables using a Mann–Whitney U test. Results: Nine patients (27.3%) had early complications, and there were no significant differences according to age, sex, treatment method, combined fractures, Pipkin classification, and AO/OTA classification between the two groups. Conclusion The prognosis in femoral head fractures is difficult to predict. Therefore, the validation of existing classifications or a new classification is necessary.

Over the last two decades, bisphosphonate has widely been applied in the treatment of osteoporosis.We reviewed the various adverse effects, current trials involving diverse bone metabolic diseases, andthe future direction of bisphosphonate. Acute phase reaction, hypocalcemia, ocular inflammation, and gastrointestinal disturbances are the well-known short-term side-effects of bisphosphonate. Long term side-effects include osteonecrosis of the jaws and atypical femur fracture. In the modern clinical setting, bisphosphonate is widely used in treatments for osteoporosis, osteopenia, osteoarthritis, rheumatoid arthritis, and metastatic bone cancer. Further studies are underway for expanding the application as a bone-targeting agent in bone-related diseases. Bisphosphonate remains useful and invaluable as the 1st line medication for osteoporosis. Considering the numerous clinical situations, including time to medication after fracture, duration of drug usage, and individual drug holiday, an optimal and proper use of bisphosphonate needs to be achieved. In the current scenario, bisphosphonate will retain a strong position due to good efficacy and effectiveness for osteoporosis treatment, and the precise ap-plication to various bone diseases. We anticipate a key role of bisphosphonate for future applicationin the treatment of metabolic bone diseases. Further studies and advancement are highly anticipated, considering the high potential of bisphosphonate for various uses.

Fracture-related infections (FRI) can occur when bacteria enter the wound during a traumatic injury. All efforts should be made to prevent FRI-associated complications due to the complexity of treatment at the time of onset and poor treatment outcomes. The risk factors for FRIs vary and several preoperative, perioperative, and postoperative measures can be implemented to prevent infections. Preoperative measures include blood sugar control, nutritional support, discontinuation of steroids and immunosuppressants, treatment of accompanying pre-existing infections, and decolonization of pathogens, specifically Staphylococcus aureus. The perioperative and postoperative measures include the use of prophylactic antibiotics, proper surgical site preparation (hair removal, preoperative washing, skin antisepsis), suitable surgical environment (operating room ventilation system, behavioral interventions in the operating room), correct surgical techniques (debridement, irrigation, wound closure, and negative pressure wound therapy). All medical staff should pay careful attention and ensure the implementation of the correct preventive measures.

Background: Femoral neck fractures need to be treated in their early stages with accurate reduction and stable fixation to reduce complications. The authors compared the early radiologic outcomes of femoral neck fractures treated with the recently introduced Femoral Neck System (FNS, Depuy-Synthes) with conventional cannulated screws (CS) in a multicenter design. Furthermore, the factors associated with early failure after FNS were analyzed. Methods: The FNS group included 40 patients treated between June 2019 and January 2020, and the CS group included 65 patients treated between January 2015 and May 2019. The operation was performed in 3 university hospitals. Patient demographics, fracture classification, postoperative reduction quality, sliding distance of FNS or CS, union and time to union, and complication rates were examined. Logistic regression analysis was performed on candidate factors for early failure of the FNS group. Results: The FNS group had a 90% union rate and a mean time to union of 4.4 months, while the CS group had similar results with an 83.1% union rate and a mean time to union of 5.1 months. In the subgroup analysis of Pauwels type III fractures, the union rates were 75.0% and 58.8% in the FNS and CS groups, respectively, and the time to union was significantly shorter in the FNS group with 4.8 months compared to 6.8 months in the CS group. Early failure rate within 6 months of FNS fixation was observed to be 10%, which included 3 reduction failures and 1 excessive sliding with a broken implant. Risk factors for early failure after FNS were identified as displaced fractures (Garden classification type III or IV), poor reduction quality, longer tip-apex distance, greater sliding distance, and 1-hole implants, of which sliding distance was the only significant risk factor in multivariate analysis. Conclusions In femoral neck fractures, FNS and CS did not show significant differences for short-term radiologic results. FNS resulted in shorter operative time than cannulated screw fixation and favorable outcomes in Pauwels type III femoral neck fractures.The FNS could be considered a reliable and safe alternative to CS when treating femoral neck fractures.

Shoulder dislocation is frequently encountered by orthopedists, and closed manipulation is often sufficient to treat the injury in an acute setting. Although most dislocations are diagnosed and managed promptly, there are rare cases that are missed or neglected, leading to a chronically dislocated state of the joint. They are usually irreducible and cause considerable pain and functional disability in most affected patients, prompting the need to find a surgical method to reverse the worsening conditions caused by the dislocated joint. However, there are cases of even greater rarity in which chronic shoulder dislocations are asymptomatic with minimal functional or structural degeneration in the joint. These patients are usually left untreated, and most show good tolerance to their condition without developing disabling symptoms or significant functional loss over time. We report on one such patient who had a chronic shoulder dislocation for more than 2 years without receiving treatment.

Purpose: Pelvis fractures are associated with bladder and urethral injury (BUI). The purpose of this study was to identify risk factors associated with BUI in patients with pelvic fracture. Methods: Patients (> 18 years) with pelvic injury (N = 314) at our hospital between January 2015 and June 2020 were retrospectively analyzed for age, sex, cause of injury, initial vital signs, urine red blood cell (RBC) count, Glasgow Coma Scale and Abbreviated Injury Scale score, Injury Severity Score, preperitoneal pelvic packing, and femur, lumbar spine, and pelvic fractures. Results: Compared with the BUI-absent group, the BUI-present group had a greater percentage of patients who were male (79.2% vs. 55.9%; p = 0.026), had a urine RBC count/high power field (HPF) ≥ 30 (94.4% vs. 38.8%; p < 0.001), underwent preperitoneal pelvic packing (37.5% vs. 18.6%; p = 0.035), had symphysis pubis diastasis (33.3% vs. 11.7%; p = 0.008), and had sacroiliac joint dislocation (54.2% vs. 23.4%; p = 0.001). Independent risk factors associated with BUI were symphysis pubis diastasis [odds ratio (OR) was 3.958 (95% confidence interval: 1.191–13.154); p = 0.025] and a urine RBC count/HPF ≥ 30 [OR = 25.415 (95% confidence interval: 3.252–198.637); p = 0.006]. Of those with BUI, 15 patients were diagnosed at the trauma bay, and 9 had a delayed diagnosis. Conclusion Patients with pelvic injury who display symphysis pubis diastasis or have a urine RBC count/ HPF ≥ 30 are at higher risk of BUI, therefore, further BUI investigations should be considered.
