Upper extremity fractures among hospitalized road traffic accident adults

BACKGROUND Upper extremity fractures (UEFs) associated with road traffic accidents (RTAs) may result in long-term disability. Previous studies have examined UEF profiles with small patient populations. The objective of this study was to examine the injury profiles of UEFs in all mechanisms of injury related to RTAs. METHODS Data on 71,231 RTA adult patients between 1997 and 2012 whose records were entered in a centralized country trauma database were reviewed. Data on UEFs related to mechanism of injury (car, motorcycle, bicycle, and pedestrian) including associated injuries, multiple UEFs, and frequency of UEF were analyzed. RESULTS Of 71,231 adult RTA cases recorded in 1997-2012, 12,754 (17.9%) included UEFs. Motorcycle (27%) and bicycle riders (25%) had the greater risk for UEF (P<.0001). Of 12,754 patients with UEFs, 9701 (76%) had other injuries. Pedestrians (86%) and car occupants (81%) had the greater risk for associated injuries (P<.0001). Most of the injuries were head/face/neck (52%), lower extremities (49%), and chest (46%) injuries (P<.0001). Twenty-two percent of all cases had multiple UEFs. The motorcycle riders (27%) had the greater risk for multiple UEFs (P<.0001). Of 12,754 patients with UEFs we found 16,371 UEFs. Most of the fractures were in the radius (22%), humerus (19%), and clavicle (17%) (P<.0001). CONCLUSIONS This study contributes the largest database on reported adult UEFs related to all mechanisms of injury in RTAs and finds the comparative epidemiology of associated injuries, multiple UEFs, and frequency of UEFs. It is important that the treating surgeon is aware of the complexity of the UEF patient, the strong possibility for associated injury, the possibility for multiple fractures in the upper limbs, and the most common fractures associated with each mechanism of accident.

The use of prophylactic antibiotics in treatment of fingertip amputation: a randomized prospective trial

PURPOSE Fingertip amputation is a common injury. Considerable controversy exists as to whether prophylactic antibiotics are necessary for this injury. Our goal was to compare the rate of infections among subgroups with and without prophylactic antibiotic treatment. The study hypothesis was that infection rates were similar in the 2 groups. METHODS This was a prospective randomized control trial of adult patients presenting with fingertip amputation with bone exposed, requiring surgical treatment. Patients were randomized to 2 groups: group 1 received no antibiotics, and group 2 received 1 g intravenous antibiotics (cefazolin) for 3 days. The 2 groups were matched for age, time to surgery, injury mechanism, and type of surgery. All surgical treatments were performed in the operating room, and all patients were reevaluated in our outpatient clinic after 10 days and again after a month. The primary outcome measure was the rate of infection. RESULTS Fifty-eight patients were initially enrolled in the study; 2 patients withdrew before study completion, 29 subjects were randomized to the no-antibiotic group, and 27 subjects were randomized to the antibiotic group. No statistically significant differences on any baseline values were found between the 2 treatment groups. There was no infection in either group at the end of follow-up. CONCLUSIONS This study suggests that routine prophylactic antibiotics do not reduce the rate of infection after fingertip amputations with bone exposed treated surgically in the operating room.

Upper extremity fractures among hospitalized pediatric road traffic accident victims

BACKGROUND Upper extremity fractures (UEFs) associated with road traffic accidents (RTAs) may result in long-term disability. Previous studies have examined UEF profiles with small patient populations. The objective of this study was to examine the injury profiles of UEFs in all mechanisms of injury related to RTAs in the pediatric population. METHODS Data on 27 831 RTA hospitalized pediatric patients between 1997 and 2012 whose records were entered in a centralized country trauma database were reviewed. Data on UEFs related to mechanism of injury (car, motorcycle, bicycle, and pedestrian) including associated injuries, multiple UEFs, and frequency of UEF were analyzed. RESULTS Of 27 831 pediatric RTA cases recorded in 1997-2012, 3666 (13.2%) included UEFs. Motorcycle (18%) and bicycle riders (18%) had a greater risk for UEF (P < .0001). Of 3666 patients with UEFs, 2047 (56%) had other injuries. The pedestrians (82%) and the motorcycle riders (78%) had a greater risk for associated injuries (P < .0001). Most of the injuries were head/face/neck (70%), lower extremities (36%), and chest (28%) injuries (P < .0001). Twenty-two percent of all cases had multiple UEFs. The bicycle riders (28%) had a greater risk for multiple UEFs (P < .0001). Of 3666 patients with UEFs, we found 4612 UEFs. most of the fractures in the radius (27%), humerus (25%), ulna (18%) and clavicle (17%) (P < .0001). CONCLUSIONS This study contributes the largest database on reported pediatric UEFs related to all mechanisms of injury in RTAs and finds the comparative epidemiology of associated injuries, multiple UEFs, and frequency of UEFs.

Treatment of physeal fractures of the distal radius by volar intrafocal Kapandji method: surgical technique

BackgroundDistal radial physeal fractures with volar displacement are rare. Several methods of operative treatment include volar plate without inserting distal screws, percutaneous technique using two anterior skin incisions and reversed Kapandji technique with pins introduced through a posterior approach and locked at the anterior cortex of the fracture.MethodsWe report three cases along with a literature review of the surgical techniques described in the past and a novel surgical technique for this uncommon fracture termed “Volar Kapandji”.ResultsAll patients had anatomic reduction at the last follow-up radiography, and all patients had a full range of motion and VAS 0 at the last follow-up. No complications were recorded.ConclusionsThis case study presents the minimally invasive option for treating rare cases of physeal distal radius fractures with volar displacement.Level of evidenceV.

Measuring the Femoral Head Size--An Additional Real-Time Intraoperative Monitoring Tool for the Accuracy of the Preoperative Process and Implant Selection.

The purpose of this study was to examine the correlation between the implanted cups outer diameter and the actual femoral head diameter removed during surgery. Seventy-five patients with primary total hip arthroplasty were evaluated. The difference between the implanted cup diameter and the femoral head diameter was calculated for each patient. The mean±SD actual femoral head diameter that was removed and measured during surgery was 48.5±3.7 mm. The mean±SD cementless implanted cup outer diameter was 51.8±3.5 mm. A high correlation was found between the implanted cup diameter and the actual femoral head diameter (r=0.923). A cut-off point of 4mm of the measured femoral head diameter should be considered as an additional monitoring indicator.

Hematoma block for distal radius fractures – prospective, randomized comparison of two different volumes of lidocaine

Objective This study aimed to compare analgesic efficacy and safety of different volumes of lidocaine injected into a fracture hematoma (hematoma block [HB]) for reducing distal radius fractures. Methods Patients were randomly divided into two groups. Group A included patients in whom 10 mL of 2% lidocaine was injected into the fracture site and group B included patients in whom 20 mL of 1% lidocaine was injected. The fracture was manipulated after 15 minutes and the Visual Analogue Scale (VAS) score was recorded during manipulation. Patients were followed up for approximately 1 hour and complications were recorded. Results Twenty patients were enrolled in the study (12 women and eight men), with a mean age of 57 years (range, 32–87 years). Demographic findings were similar between the groups. The mean VAS score of group A was 5.50 ± 3.57 and that in group B was 3.09 ± 2.33, with no significant difference between the groups. Conclusion VAS scores between HB with 20 mL of 1% lidocaine and HB with 10 mL of 2% lidocaine are not significantly different. However, our study suggests that HB with 20 mL of 1% lidocaine has a better analgesic effect than HB with 10 mL of 2% lidocaine.

Open reduction and internal fixation of intra-articular distal radius fractures under wide-awake local anesthesia with no tourniquet

Objective The use of wide-awake local anesthesia with no tourniquet (WALANT) is becoming an excellent alternative for elective hand surgeries and hand surgeries involving minor trauma. Although the use of WALANT for some soft tissue surgeries has become the state of the art, data regarding bony procedures, such as fracture management, under WALANT are limited. This study was performed to assess the WALANT technique for open reduction and internal fixation of distal radius fractures. Methods Five patients with displaced distal radius fractures were enrolled in the study. WALANT was carried out about 30 minutes prior to the first incision. Surgery was performed in the normal fashion, and the fractures were fixed using anatomic locking plates. After surgery, the patients were admitted overnight for observation and pain assessment, and they were discharged within 24 hours postoperatively. Intraoperative and postoperative complications were recorded. Follow-up was performed in our outpatient clinic. No abnormalities were recorded. Results All patients underwent a successful painless surgery. No extra bleeding or other complications were recorded. Conclusion The WALANT technique offers a simple and safe alternative to traditional anesthetic techniques for open reduction and plating of distal radius fractures.

Can a linear external fixator stand as a surgical alternative to open reduction in treating a high-grade supracondylar humerus fracture?

Objective High-grade pediatric supracondylar humerus fractures are commonly treated with closed reduction and internal fixation with percutaneous pinning. When this fails, open reduction followed by internal fixation is the widely accepted procedure of choice. Use of a lateral external fixator was recently described as an optional procedure, but evidence is scarce. Methods We investigated the outcomes of upper limbs treated by either open reduction with internal fixation or closed reduction and external fixation. Results Twenty-one patients completed the long-term follow-up; 11 underwent open reduction, and 10 underwent external fixation. Most patients in both groups reported excellent satisfaction. In both groups, the modified Disabilities of the Arm, Shoulder, and Hand score was extremely low and the average elbow range of motion was almost identical. Radiographic analysis consisting of Baumann’s angle and the carrying angle revealed no statistical difference between the two groups. Discussion Optional treatment using a linear external fixator for complex nonreducible supracondylar humerus fractures yielded acceptable clinical and radiographic results, as with open reduction. Our sample size was small, but the promising results may assist in the implementation of an alternative surgical procedure, especially in more complicated cases involving flexion-type fractures or severe soft tissue damage and swelling.

The effectiveness of splinting and surgery on sleep disturbance in carpal tunnel syndrome

This controlled prospective study assessed the effectiveness of night splinting compared with non-splinting and surgery for severity of insomnia in patients with carpal tunnel syndrome. Sleep characteristics were observed for several days without a brace, with a brace and after surgery. The sleep measurements included the use of an actigraph worn on the wrist during night, a ‘sleep log’ that conveyed subjective impressions as to how the patient had slept and a short insomnia instrument, the Insomnia Severity Index. The Insomnia Severity Index scores showed that a night splint significantly improved insomnia symptoms compared with no splinting, and surgery significantly improved insomnia symptoms compared with splinting. The sleep log scores showed that the sleep quality and the number of awakenings when a splint was not worn were significantly different from the scores with the splint and the scores after surgery but showed no differences between splint and surgery. The actigraph did not show any significant differences between the treatment methods. Level of evidence: III

Computed navigated total knee arthroplasty compared to computed tomography scans

BACKGROUND Successful total knee arthroplasty (TKA) includes accurate alignment. Controversy remains as to whether computer-navigated TKA improves the overall result and clinical outcome. Our aim is to compare the limb alignment and prosthesis positioning according to the pre- and postoperative computed tomography (CT) scans with the data collected from the navigation system. METHODS We compared the pre- and postoperative limb alignments and prosthesis alignment provided by the Orthopilot navigation system, Aesculap®, with CT scans measured by the Traumacad® software of 70 TKAs. RESULTS A positive correlation with statistical significance (P=0.00001, r=0.874) between the navigation system data and the CT images was found. Mean femoral cut was five degrees (valgus), and mean tibial cut was one degree (varus). Our study revealed that the navigation system assisted the surgeon to implant the prosthesis at a good acceptable alignment. CONCLUSION We found that the navigation system is accurate and correlates to the pre- and postoperative CT scans. Furthermore, the navigation system can assist the surgeon to achieve good limb alignment and cutting planes of the prosthesis.
