ABSTRACT
Background@#Although most studies focused on the alignment or union of the tibia in same-level distal third tibiofibular fractures, the outcome of a concomitant fibular fracture is generally regarded as being of secondary importance in the literature. This study aimed to assess the outcomes of fibular fractures in same-level distal third tibiofibular fractures. @*Methods@#In this retrospective study, we enrolled 111 patients with same-level distal third tibiofibular fractures treated at our institute between January 2016 and August 2020. Tibial fractures were stabilized with intramedullary nailing, and the cases were divided into two groups based on whether they additionally underwent fibular fixation (group 1, 57 cases) or not (group 2, 54 cases). Clinical and radiographic outcomes were used for the evaluation of tibial and fibular alignments, union of the tibia and fibula, number of interlocking screws in the distal tibial fragment, range of motion of the ankle joint, and complications. @*Results@#No statistically significant differences in the tibial union rate or mean tibial alignment were observed between the two groups on either the immediate postoperative or final radiographs. The fibular union rate in group 1 was significantly higher than that in group 2 (fibular nonunion, 0 vs. 15; p < 0.001). Statistically significant differences in fibular displacement were observed on immediate postoperative radiographs between patients with fibular union and those without it. At the final follow-up, the mean range of ankle motion and lower extremity functional scale scores did not differ between the two groups. @*Conclusions@#Regardless of whether fibular fixation was performed, the overall tibial alignment with intramedullary nailing was well restored and the union rate of the tibia was comparable in the two groups. Fibular nonunion is not uncommon in unfixed fibula fractures. Displacement of the fibula as seen on immediate postoperative radiographs was related to fibular nonunion.
ABSTRACT
Background@#Vitamin D concentrations are associated with sepsis, pneumonia, and mortality in critically ill patients. However, the role of vitamin D in critically injured patients with trauma remains unknown. This study investigated the effects of vitamin D concentrations on outcomes in critically injured patients with trauma. @*Methods@#A prospective observational study was conducted by randomly selecting 100 patients among those who visited our trauma center. The serum vitamin D concentration was measured upon arrival at the hospital, and the length of stay in a trauma intensive care unit after admission, duration of mechanical ventilation, number of days spent in the hospital, development of complications, and death were investigated. The association between the surveyed variables and vitamin D concentrations was investigated using regression analysis. @*Results@#Of the 100 patients, 69 were men and 31 were women with an average age of 51.7 years. The average intensive care unit stay length was 18.4 days, and 6 patients (5.9%) died. Univariate regression analysis showed that the factors affecting patient mortality were age (p = 0.02), volume of blood transfused within 24 hours of arrival (p = 0.009), systolic blood pressure measured upon hospital arrival (p = 0.01), and serum lactate concentration measured upon hospital arrival (p = 0.03). Multivariate regression analysis showed that the factors affecting patient mortality were age (p = 0.01), volume of blood transfusion (p = 0.04), and systolic blood pressure measured upon hospital arrival (p = 0.01). @*Conclusions@#There were no statistically significant effects of serum vitamin D concentrations in critically ill patients with trauma on death during hospitalization.
ABSTRACT
A crush injury causes damage to bones, muscles, blood vessels, nerves, and other tissues caused due to pressure. Crush syndrome is a reperfusion injury that occurs throughout the body after a crush injury and leads to traumatic rhabdomyolysis, in which muscle fibers are broken down. Owing to the decreased blood supply, inflammation, and changes in metabolic activity, fluids and electrolytes in the blood can move into tissues, causing hypovolemic shock. In addition, toxic substances resulting from cell destruction can circulate through the bloodstream, causing electrolyte imbalances, renal failure, arrhythmias, and cardiac arrest, with approximately 15% of patients with acute renal failure dying. The treatment for crush syndrome involves aggressive fluid therapy and correction of the electrolyte imbalances, while patients with acute renal failure may require dialysis. Surgical treatment may include debridement and irrigation of necrotic tissue, and fasciotomy is necessary to address compartment syndrome, a complication that may arise.
ABSTRACT
Purpose@#Although many studies have reported the use of dynamic hip screws (DHS) and cephalomedullary nailing (CMN) for basicervical femoral neck fracture (BFNF), no clear treatment protocols have been recommended. The present study aimed to compare the surgical outcomes associated with DHS and CMN to determine the appropriate fixation method for BFNF. @*Materials and Methods@#We systematically searched MEDLINE, Embase, and the Cochrane Library for studies published up to January 9, 2021 that compared the treatment outcomes between CMN and DHS in BFNF. The primary outcomes of the present meta-analysis were fracture union time, postoperative cut-out rate, and reoperation rate. @*Results@#We included seven studies involving 353 cases of BFNF in our review. Of these, 206 patients were treated using CMN, and DHS were utilized in 147 patients. In a pooled analysis, the DHS group required a longer time to achieve fracture union compared to the CMN group [mean difference (MD): -0.41; 95% confidence interval (CI): -0.70, -0.12; p=0.006; I 2 =0%]. However, the cut-out and reoperation rates exhibited no statistically significant differences between the DHS and CMN groups [cut-out odds ratio (OR): 0.54; 95% CI: 0.10, 2.82; p=0.47; I 2 =24%, reoperation rate OR: 0.65; 95% CI: 0.15, 2.86; p=0.57; I 2 =19%, respectively]. @*Conclusion@#Stable fixation using DHS and CMN does not show a significant clinical or radiographical difference in BFNF, and the implant can be selected based on the surgeon’s preference.
ABSTRACT
Purpose@#Distal tibia fractures with severe soft-tissue edema or intra-articular fractures are treated by staged operations using external fixators. Definitive surgery that maintains ligamentotaxis has been difficult using existing fixators. This study introduced a novel ‘box-frame’ external fixator and evaluated its clinical usefulness. @*Materials and Methods@#This study included 45 patients (32 males, 13 females) diagnosed with distal tibia fractures who underwent staged operations between March 2012 and March 2016, with a follow-up of at least one year. The patients were divided into two groups. In one group, fixation was performed with a box-frame external fixator (Group A). In the other group, fixation was performed with a delta-frame external fixator (Group B). The following outcomes were evaluated: the time until definitive surgery, operative time of the definitive surgery, radiation exposure time, bone union, time to achieve bone union, postsurgical complications, American Orthopaedic Foot & Ankle Society anklehindfoot score, and ankle range of motion. @*Results@#Compared to the delta-frame, the box-frame showed a statistically significant reduction in the mean radiation-exposure time and operative time during the definitive surgery by 58 seconds and 25 minutes, respectively. The differences in the time until definitive surgery, bone union, time to achieve bone union, postsurgical complications, and functional scores were not significant. @*Conclusion@#The box-frame external fixator can be a useful treatment method in the staged surgery of distal tibia fractures.
ABSTRACT
Heterotrophic ossification (HO) is a reactive disease presenting the formation of mature lamellar bone in soft tissues. It is known to occur following surgery, soft tissue injury, or central nervous system anomalies. However, a definite cause has not yet been clearly addressed. During the process of approach, reduction, and fixation while conducting surgeries, partial injury of soft tissue is inevitable. Additionally, secondary injuries may be caused during the active and passive range of motion exercises that should be done for the recovery of joint motion after surgery. The authors experienced cases of HO that may occur during surgery and rehabilitation after surgery. The authors recognized that special care is required for patients complaining of severe pain during the early stage of rehabilitation immediately after surgery. This study aimed to reaffirm the principles of fracture treatment by reviewing the cases and to investigate the occurrence of HO after fracture surgery.

PURPOSE: This study investigated the clinical and radiological outcomes of patients undergoing provisional fixation in conjunction with locking plate fixation. Miniplates were used as the reduction plates for the surgical treatment of severe comminuted metadiaphyseal fractures with an intra-articular fracture of the distal radius. MATERIALS AND METHODS: The radial length, radial inclination, volar tilt, and radial intra-articular step-off were measured preoperatively, postoperatively, and at one year after surgery in 12 patients (eight males, four females, mean age 55.4 years old). The patients underwent volar locking plate fixation with miniplate as a reduction plate for severe comminuted metadiaphyseal fractures with an intra-articular fracture of the distal radius. Clinical evaluations were conducted using the modified Mayo wrist score (MMWS). RESULTS: Bone union was achieved in all cases. The mean MMWS was 81.8 points, including two excellent, three good, and seven fair cases. Radiological improvements were observed in the average radial length (preoperative, 6.4 mm; postoperative, 11.8 mm), average radial inclination (10.2° to 22.4°), average volar tilt (−4.5° to 10.6°), and average radial intra-articular step-off (4.8–0.8 mm) (all, p0.05). CONCLUSION: Miniplate fixation can be an effective treatment option as a reduction plate for the treatment of distal radial fractures, which is challenging to reduce and maintain due to severely comminuted metadiaphysis fractures with the intra-articular fracture.

Fractures and dislocation of the hand is a body injury involving complex structures and multiple functions, which frequently occur as they represent 10%-30% of all fractures. Such fractures and dislocation of the hand should be treated in the context of stability and flexibility; and tailored treatment is required in order to achieve the most optimal functional performance in each patient since deformation may occur if not treated, stiffness may occur with unnecessarily excessive treatment, and both deformation and stiffness may occur coincidently with inappropriate treatment. Stable injuries can be fixed with splintage whereas surgery is actively considered for unstable injuries. In addition, surgeons should keep in mind that as the surgical intervention is done aggressively, aggressive rehabilitation must be followed in correspondence with the surgical intervention. Successful outcome requires effort to prevent any potential complication including nerve hypersensitivity and infection. Finally, it is also important that the patient to know that swelling, stiffness, and pain may last for a long period of time until the recovery of fractures and dislocation of the hand.

PURPOSE: The purpose of this study is to compare the clinical and radiological results between posteromedial portal technique and posterior transseptal portal technique in making a tibial tunnel in single bundle posterior cruciate ligament (PCL) reconstruction with remnant preservation. MATERIALS AND METHODS: Thirty-three cases of posteromedial portal technique and 35 cases of posterior transseptal portal technique in making a tibial tunnel in single bundle PCL reconstruction with remnant preservation were evaluated retrospectively. The clinical evaluation, including function and stability, was assessed. The tibial tunnel placement was measured using computed tomography. RESULTS: At final follow-up, the clinical results showed significant improvement compared to preoperation in both groups. There were no significant differences in clinical results including function and stability in both groups. The centers of tibial tunnels by posteromedial portal technique were placed more medially and proximally than those of the posterior transseptal portal technique. CONCLUSION: Remnant preserved single bundle PCL reconstructions by posteromedial portal technique and posterior transseptal portal technique were good methods for restoring function and stability compared to preoperation. There were no significant differences in clinical results in both groups. However, the tibial tunnels by posteromedial portal technique tended to be more medial and proximal placements than those of the posterior transseptal portal technique.

PURPOSE: We investigate the outcomes of treatment of patients with severe comminuted distal radius fractures with volar plate fixation using a pronator-preserving approach. MATERIALS AND METHODS: Fourteen patients with severe comminution of the distal radius fractures for whom anatomical reduction of the fractures was deemed difficult to achieve with traditional approaches were enrolled. The gender ratio was 8 males to 6 females, and the average age of the patients was 64.9 years. According to the AO/OTA classification of fractures, 2 patients had 23-A3 fractures, 7 patients had 23-C2, and 5 patients had 23-C3. Radial length, radial inclination, and volar tilt were measured for radiologic evaluation. Modified Mayo wrist score (MMWS) was used for clinical outcome. RESULTS: Bony union was achieved in all 14 patients without signs of complications. The average time-to-union was 4.3 months (3-6 months). The radiological findings at the final follow-up were as follows: the average radial inclination was 20.5degrees; the average volar tilt, 7.57degrees; and the average radial length, 11.8 mm. At the final follow-up, the results of the MMWS were 'Fair' in 1 patient, 'Good' in 4, and 'Excellent' in 9. CONCLUSION: We propose that a pronator-preserving approach is an effective treatment for severe comminuted distal radius fracture.

PURPOSE: In early prosthetic joint infection after hip arthroplasty, debridement with prosthesis retention may be performed for implant salvage, but the reported success rates are highly variable. Hence we reviewed the outcome of radical debridement and retention of prosthesis using established diagnostic criteria and surgical procedures in relation to significant variables including clinical characteristics, pathogenicity, and antibiotic treatment. MATERIALS AND METHODS: We retrospectively reviewed 20 patients (11 men and 9 women) with early prosthetic joint infection after unilateral hip arthroplasty, treated by radical debridement with retention of prosthesis from January 2000 to May 2011. Average follow-up period was 55 months (12-178 months). The outcome was evaluated and analyzed based on recurrence of infection and clinical (Harris hip score) and radiological criteria. RESULTS: Pathogens were isolated from 11 hips (methicillin-resistant Staphylococcus aureus [MRSA] in three, methicillin-resistant Staphylococcus epidermidis [MRSE] in two, methicillin-sensitive Staphylococcus aureus [MSSA] in one, Acinetobacter baumannii in two, Enterococcus faecalis in two patients, and Enterococcus, Citrobacter species in one). The mean duration of antibiotic administration was 43.5 days. Recurrence of infection was not observed in any case. Average Harris hip score was 91 points at the last follow-up. Revision surgery was not required for any reason including implant failure. Dislocation occurred in two hips after debridement and was treated conservatively. CONCLUSION: Radical debridement with prosthesis retention is an effective procedure for early prosthetic joint infection after hip arthroplasty in carefully selected patients and with early diagnosis.

BACKGROUND: The purpose of this study was to compare the initial stability of anatomical and non-anatomical single bundle anterior cruciate ligament (ACL) reconstruction and to determine which would better restore intact knee kinematics. Our hypothesis was that the initial stability of anatomical single bundle ACL reconstruction would be superior to that of non-anatomical single bundle ACL reconstruction. METHODS: Anterior tibial translation (ATT) and internal rotation of the tibia were measured with a computer navigation system in seven pairs of fresh-frozen cadaveric knees under two testing conditions (manual maximum anterior force, and a manual maximum anterior force combined with an internal rotational force). Tests were performed at 0, 30, 60, and 90 degrees of flexion with the ACL intact, the ACL transected, and after reconstruction of one side of a pair with either anatomical or non-anatomical single bundle ACL reconstruction. RESULTS: Under manual maximal anterior force, both reconstruction techniques showed no significant difference of ATT when compared to ACL intact knee state at 30degrees of knee flexion (p > 0.05). Under the combined anterior and internal rotatory force, non-anatomical single-bundle ACL reconstruction showed significant difference of ATT compared to those in ACL intact group (p 0.05). Internal rotation of the tibia showed no significant difference in the ACL intact, the ACL transected, non-anatomical reconstructed and anatomical reconstructed knees. CONCLUSIONS: Anatomical single bundle ACL reconstruction restored the initial stability closer to the native ACL under combined anterior and internal rotational forces when compared to non-anatomical ACL single bundle reconstruction.

PURPOSE: The author evaluated the clinical and radiological results after wearing the medial arch supports in children. MATERIALS AND METHODS: 103 patients who had symptomatic flat feet were evaluated from march, 2002 to may 2009. All patients wore the medial arch supports according to the symptoms. We measured parameters at weight-bearing radiographs before and after medial arch support were worn. We also evaluated the clinical scores using the AOFAS score. RESULTS: Mean age of patients was 97 months (11-204 months), all foot of patients involved bilaterally. Mean talo-first metatarsal angle of right foot was 17.7+/-9.4 and left foot was 19.96+/-9.5 degrees at AP radiograph in pre-wearing state. Mean calcaneal pitch angle of right foot was 12.0+/-5.3 and left foot was 11.9+/-5.8 degrees at lateral radiograph in pre-wearing state. Mean talo-first metatarsal angle of right foot was 14.4+/-8.05 and left foot was 13.1+/-8.77 degrees at AP radiograph in post-wearing state. Mean calcaneal pitch angle of right foot was 16.4+/-5.75 left foot was 16.5+/-5.6 degrees at lateral radiograph in post-wearing state. The radiographic angles between pre-wearing and post-wearing state were statistically significant (p<0.05). Mean pre-wearing AOFAS hindfoot score was 66.7+/-9.25, midfoot score was 60.0+/-9.34 forefoot score was 57.1+/-11.8. Mean post-wearing AOFAS hindfoot score was 73.2+/-9.73, midfoot score was 68.1+/-10.1, forefoot score was 67.2+/-11.4. The forefoot score was highest improving scores among the AOFAS scores. CONCLUSION: From our study, we concluded that medial arch support was effective for symptomatic flat feet of children in radiological and clinical results from our study.
