Does skyline view prevent extensor tendon pathologies during volar plating of distal radius? An ultrasonographic evaluation.

OBJECTIVES: This study aims to compare extensor tendon complications of volar plating in distal radius fractures between skyline and lateral views by using postoperative ultrasonography (USG). PATIENTS AND METHODS: Between January 2019 and February 2020, a total of 82 distal radius fractures of 79 patients (39 males, 43 females; median age: 56±12.9 years; range, 23 to 79 years) who were operated with distal four-hole plates and had a follow-up period of at least three months were retrospectively analyzed. During distal radius locking plating, standard lateral fluoroscopic view was used in 36 distal radius fractures and skyline view in addition to lateral view was used in 46 cases. A median of five months later, the protruding screws and extensor compartments were evaluated with USG. The number of screws with dorsal penetration, extent of penetration, and extensor tendon complications were compared between skyline and lateral view groups. RESULTS: In the skyline view group, the rate of dorsal screw penetration was significantly lower than that of the lateral view group (7.3% vs. 14.7%, respectively; p<0.05). Additionally, the rate of extensor tenosynovitis was lower in the skyline view group than in the lateral view group (15% vs. 39%, respectively; p<0.05). No significant difference was seen in the extent of penetration between the groups (1.4 vs. 1.65 mm, respectively; p=0.089). The second compartment had the highest risk for dorsal screw penetration. One case of tendon rupture in the third compartment occurred in the lateral view group. CONCLUSION: The skyline view seems to be an effective method to prevent extensor tendon complications caused by protruding screws.

Does the COVID-19 pandemic period itself increases early mortality rates of elderly patients with hip fractures in Turkey?

ABSTRACT: Hip fractures are common in elderly patients and prone to serious morbidity and mortality particularly when the treatment is delayed. The objective of this study was to evaluate the effect Coronavirus disease of 2019 (COVID-19) pandemic on the early mortality rates of geriatric patients with hip fractures.281 patients who were followed and operated on with the diagnosis of proximal femur fracture were included in this retrospective study. Patients were divided into 2 groups, that is, 180 patients presenting between March and June 2018 to 2019 (prepandemic period) and 101 patients presenting between March and June 2020 (pandemic period). Age, sex, type of fracture, time from fracture to presentation to hospital, comorbidities, time from admission to operation, length of intensive care unit stay, length of hospital stay, and mortality rates were retrieved from hospital records and evaluated.While there was no significant difference in terms of age, sex, type of fracture, in-hospital mortality, 30-day mortality, time to surgery, Charlson comorbidity index and length of intensive care unit stay through pandemic and prepandemic period (P > .05), significant differences were observed in terms of length of hospital stay, time to admission, refusal of hospitalization and attending outpatient visits regularly (P < .05). Attending outpatient visits and the length of hospital stay were the main significant differences in multivariate analysis.The early mortality rates in patients with hip fractures were similar during the pandemic period to before in Turkey. However, the length of hospital stay was prolonged and more patients refused the treatment and fewer of them attended regular outpatient controls in the pandemic.

Rear drop: a new radiographic landmark for estimation of pelvic tilt on pelvis AP radiographs.

Estimation of pelvic tilt on anteroposterior (AP) pelvis radiograph is often done by indirect methods based on the midline pelvic landmarks. The purpose of this cadaveric study is to describe a new radiographic landmark and reference measurements to estimate the coronal tilt of the pelvis, independent of the midline references. The new radiologic reference is called 'rear drop', and its anatomic location is described with the cadaveric pelvis AP radiographs in various pelvic inclination. The parameters derived from the new reference were used to assess the pelvic tilt, and the results were compared with the previously established method using 'sacrococcygeal joint to symphysis distance' (SCSD). The shape of the new figure is used to determine the position of the pelvis, and its relationship with the previously described acetabular retroversion indicators was statistically analyzed. The new reference figure corresponds to the posteroinferior edge of the horseshoe shape of the acetabular margin. The newly derived reference parameters, rear to tear distance and rear to tear angle, changes with pelvic tilt and are strongly correlated with SCSD. The shape of the rear drop changes with the changing pelvic tilt and correlates statistically with the previously described acetabular retroversion indicators. Rear drop and its derivative measurements can be used as a reliable and reproducible indicator to estimate the coronal pelvic tilt, free of midline reference points. This new reference will be a base for future clinical studies on pelvic tilt, rotation and their application in intraoperative hip fluoroscopy.

The use of the wide-awake local anesthesia no tourniquet technique in foot and ankle injuries.

PURPOSE: Although the wide-awake anesthesia no tourniquet (WALANT) technique has demonstrated high efficacy, safety, patient satisfaction, and cost-effectiveness in hand surgery, there are limited data on its use in foot and ankle surgery. This study aimed to evaluate the efficacy of the WALANT technique in selected foot and ankle injuries in terms of intra- and post-operative characteristics. MATERIAL AND METHODS: Patients with foot and ankle injuries who underwent surgery with the WALANT technique were evaluated in this retrospective study. A total of 31 patients (22 male/9 female) with a mean age of 40 ± 16 years were evaluated for the type of injury, underlying comorbidities, American Society of Anesthesiologists Classification (ASA) score, intraoperative visual analog pain (VAS) and anxiety (VAS-A) scores, duration of operation, complications, need for intensive care and duration of hospitalization. RESULTS: There were 15 patients with medial malleolus fracture, 5 with lateral malleolus fracture, 5 with Achilles tendon ruptures, 2 with proximal phalangeal fracture, and 1 with Lisfranc injury, medial malleolus + syndesmotic injury, deltoid ligament + syndesmotic injury and fifth metatarsal fracture. ASA I-II score was determined in 27 patients and ASA III score in 4. The mean operation time was 36.6 ± 7 min, and the mean length of hospital stay was 8.3 ± 6.1 h. The median VAS pain score was 1 (range, 0-4), the median VAS-A score was 1 (range, 0-3) and no patient needed further anesthetics during the operation. No patient needed intensive care unit stay and no complications were observed in any patient. CONCLUSION: The WALANT technique was seen to provide satisfactory anxiety and pain scores, acceptable complications, and a short length of hospital stay in patients with foot and ankle injuries. Simple foot and ankle injuries can be managed successfully with this technique through adequate hemostasis without a tourniquet. LEVEL OF EVIDENCE: Level III.

Acetabular Surgery in the Prone Position Resulting in a Life-Threatening Splenic Injury: A Case Report.

CASE: The case reported involves a patient who developed an unexplained decrease in hemoglobin after acetabular fracture surgery in the prone position. Repeat abdominal computed tomography was remarkable for a massive subcapsular spleen hematoma secondary to rib fracture impingement, which required splenectomy. CONCLUSION: The spleen can be injured by a fracture rib during prone positioning for fixation of an acetabular fracture. Prone surgical positioning may cause iatrogenic intra-abdominal organ injury in patients with displaced lower rib fractures. Lateral positioning should be considered for acetabular surgery in patients with rib fractures.

Is there any change in surgeon's attitude to the management of ankle fractures accompanying syndesmotic injury? A nationwide survey.

OBJECTIVES: This study aims to investigate the attitudes of orthopedic surgeons to the management of ankle fractures accompanied by syndesmotic injury with a nationwide survey. PATIENTS AND METHODS: In the first step of this descriptive study, an electronic survey was prepared in Google drive and a survey link was sent to the Turk-Ortopedi e-mail group between 09 and 19 January 2019. The orthopedic surgeons and residents were requested to complete the questionnaire. A total of 320 orthopedic surgeons (77%) and residents (23%) participated in the survey. The responses were analyzed statistically. To evaluate the changing attitudes, our results were compared with the surgeon survey studies key worded "syndesmotic injury" in PubMed. RESULTS: The majority of the participants stated that they used the hook test, external rotation stress test, and fluoroscopy together (47.2%) for the diagnosis of syndesmotic injury during the operation. Of the participants, the majority (93%) reported to use metallic syndesmotic screws, and 59% reported to remove the syndesmotic screw routinely. Young surgeons with 5 to 10 years of experience preferred intraoperative diagnosis methods compared to surgeons with more than 20 years of experience. Foot and ankle surgeons and sports surgeons reported to allow weight bearing before removal of the screw much more than other unspecified branches. CONCLUSION: The preferences of the surgeon vary in syndesmotic injuries and there is still no consensus regarding diagnosis and rehabilitation. Compared to the past decade, fewer surgeons prefer to remove the screws today.

Correlation of pelvic fractures and associated injuries: An analysis of 471 pelvic trauma patients.

BACKGROUND: In most respects, the vast majority of pelvic injuries is not of a life-threatening status, but co-presence of other injuries needs to be diagnosed. This study aims to evaluate associated pelvic and extra-pelvic visceral organ injuries of the patients with closed pelvic fractures. METHODS: This retrospective study was conducted with 471 adult patients who had been admitted to our Emergency Service with the diagnosis of pelvic fractures. Type of fractures, accompanying visceral organ injuries, the demographic data, type of operation, mortality rates were recorded and analysed statistically. RESULTS: The rate of operations carried out by the general surgery clinic or other surgical clinics in each type of fracture according to AO classification did not differ (p=0.118). In patients with A2, A3 and B1 types of fractures, the operation rate of general surgery clinic did not show a significant difference. However, most of the patients who had extrapelvic surgery were in the mild severity pelvic trauma, such as AO A2 and A3. A total of 31 patients were ex-patients, 17 of whom had AO-A2 type of fractures. The findings showed that there was a significant difference between abdominal ultrasonography outcome that was normal and non-orthopedic surgery types (p<0.001). There was no significant difference between the types of surgery performed and Abdominal CT outcome, which was normal (p=0.215). CONCLUSION: In the management of patients with pelvic fractures irrespective of its type or grade, the findings suggests that greater attention should be paid to not to overlook the associated injuries. Early blood and imaging tests are encouraged after the patient's hemodynamic status is stabilized.

Comparison of different locking plate fixation methods in lateral malleolus fractures.

BACKGROUND: Several fixation methods may be used for displaced lateral malleolar fractures. We aimed to compare clinical and radiologic outcomes associated with use of locking one third tubular plate vs. anatomical distal fibula locking plate in lateral malleolar fractures. METHODS: A total of 62 orthopedic patients operated for lateral malleolus fracture were included in this retrospective study. Patients were divided into two groups regarding the plate used for fixation as locking one third tubular plate (group I; n=37) and locking anatomical distal fibula plate (group II; n=25). Data on Danis-Weber ankle fracture classification (Type A, Type B), duration of follow up, clinical outcome [ankle range of motion (ROM), American Orthopaedic Foot & Ankle Society (AOFAS) score], radiological outcomes (adequacy of reduction, loss of alignment), time to fracture healing and complications were recorded in study groups. RESULTS: No significant difference was noted between groups in terms of AOFAS score [87.0 (73-100) vs. 85.0 (71-100), respectively (p=0.339)] and no patients had severe restriction in sagittal and hindfoot motion in both groups. The two groups showed similar healing time [9.0 (7-13) weeks vs. 10.0 (8-13) weeks, respectively (p=0.355)] and complication rate [0.0% vs. 4.0%, respectively (p=0.403)]. CONCLUSIONS: This study revealed no significant difference between use of locking one third tubular plate and locking anatomical distal fibula plate in lateral malleolar fixation, in terms of clinical and radiological outcomes, complication rates and fracture healing time.

Combined arthroscopic synovectomy and radiosynoviorthesis in the treatment of chronic non-specific synovitis of the knee.

INTRODUCTION: Chronic non-specific synovitis has a higher recurrence rate with arthroscopic synovectomy due to the insufficient removal of all pathological tissues. Neither has radiosynoviorthesis been sufficiently effective in treatment in contrast to cases of chronic specific synovitis such as rheumatoid arthritis. This study aimed to investigate the efficiency of combined arthroscopic and radionuclide synovectomy in chronic non-specific synovitis of the knee with the evaluation of clinical and radiological results. MATERIALS AND METHODS: 14 knees of 14 patients (11 female, 3 male) diagnosed as chronic non-specific synovitis were treated with arthroscopic subtotal synovectomy combined with radiosynoviorthesis. The efficiency was evaluated retrospectively by comparing preoperative and postoperative modified cincinnati knee score, Visual Analogue Scale, joint USG and MRI. The mean age was 29.2 ± 10.3 years and the mean follow-up period was 30.3 ± 3.7 months. RESULTS: Clinical parameters such as pain, limitation of motion and effusion were regressed. Daily activities at the final follow-up were significantly better than in the preoperative period. The mean modified cincinnati knee score of the patients increased from 25.8 ± 8.7 preoperatively to 67.8 ± 13.4 postoperatively (p = 0.002). The mean VAS score was 7.2 ± 1.1 preoperatively and 1.3 ± 0.8 postoperatively (p = 0.003). Clinically and radiologically on MRI there was no recurrence. Mean synovial membrane thickness was 4.5 ± 2.4 mm in the preoperative period. At the final follow-up, noticeable regression of synovial membrane thickness (2.1 ± 0.5 mm) was recorded in the knee joint USG (p = 0.015). No complications were observed. CONCLUSION: The combination of arthroscopic subtotal synovectomy and radiosynoviorthesis can be an effective treatment modality for chronic non-specific synovitis of the knee.

Cam impingement of the posterior femoral condyle in unicompartmental knee arthroplasty.

PURPOSE: There has been much emphasis on the importance of cam impingement, which is a cause of pain and knee hyperflexion restriction in unicompartmental knee arthroplasty (UKA). This study aimed to correlate cam impingement in the posterior femoral condyle with an α-angle showing the severity of the impingement. METHODS: The study groups consisted of 87 knees of 74 patients operated on with phase 3 medial Oxford UKA. Postoperatively, Group A (68 knees, 78.2 %) had no remnant of cam lesion; Group B (19 knees, 21.8 %) had cam lesion remnants. In Group C (18 knees, 20.7 %), which is a subgroup of Group A, cam lesions seen preoperatively were cleaned and not seen postoperatively. RESULTS: The mean increase in active flexion was 20.4° (± 7.3°) in Group A, 9.7° (± 6.1°) in Group B and 20.8° (± 7.3°) in Group C. The difference between Group A and Group B and between Group B and Group C was statistically significant (p < 0.001, p < 0.001). The mean decrease of α-angle was 11.2° (± 4.1°) in Group B, and 31.1° (± 3.4°) in Group C. The difference was statistically significant (p < 0.001). Mean Oxford Knee Scores were 24 preoperatively, 41 postoperatively in Group A; 22 preoperatively, 38 postoperatively in Group B; and 24 preoperatively, 40 postoperatively in Group C. The differences were not significant. CONCLUSIONS: Posterior condylar cam lesion is an impingement which limits hyperflexion and may be an early clinical finding prior to bearing dislocation and wear. The α-angle is a marker showing the severity of this cam lesion. This problem can be overcome using intraoperative fluoroscan views during cam excison and replacing the femoral component in 105° knee flexion.

Robotic arthroscopic surgery: a new challenge in arthroscopic surgery Part-I: Robotic shoulder arthroscopy; a cadaveric feasibility study.

BACKGROUND: Arthroscopy of the shoulder is a well-established diagnostic procedure which has widespread application. Advances in technology and the search for more minimal invasive surgery will always offer new techniques in any surgical field. Robotic technology is such an advance, offering technical advantages over standard laparoscopic approaches. The aim of the present study is to test whether robotic surgery can be used while performing shoulder arthroscopy or not. METHODS: Robotic shoulder arthroscopy was tried on two shoulder joints of a male fresh-frozen human cadaver. The arthroscopic control of the biceps tendon, glenoid labrum, rotator cuff muscles, rotator interval, glenohumeral ligament, and the coracoid process were evaluated in beach chair and lateral decubitus positions. RESULTS: The arthroscopic control of the shoulder joint was possible for both beach chair and lateral decubitus positions. CONCLUSIONS: Robotic shoulder arthroscopy seems feasible in a cadaveric model but has some significant limitations at this time. A clinical application could be performed as diagnostic arthroscopy and as simple arthroscopic surgery until more specific instrumentation is developed. It may also enable the surgeon to perform more complex and precise tasks in restricted spaces.
