A device that facilitates screwing at an appropriate angle in quadrilateral surface fractures: 105-degree drill attachment.

BACKGROUND: Within this study, we aimed to investigate the radiological and functional outcomes of acetabular fractures involving quadrilateral surface using 105° drill attachment in the anterior intrapelvic approach. METHODS: The 35 patients who underwent surgical treatment from January 2016 and January 2020 for acetabular fractures involving quadrilateral surface with anterior intrapelvic approach using 105° drill attachment and a minimum of 12 months of postoperative follow-up were included. Perioperative complications, operation duration, and the quality of reduction were evaluated. Reduction quality was classified as poor, imperfect, and anatomic. Functional evaluation was performed according to the Harris Hip Score (HHS) and Merle d'Aubigne Score. RESULTS: Among 35 patients (median age 36 (21-80)), radiological results of the acetabular fixations were anatomic, imperfect, and poor in 28 (80%), 5 (14.3%), and 2 (5.7%) patients, respectively. Postoperative 1-year functional outcomes with Merle d'Aubigne scores and HHS were median 18 (10-18) and 90 (60-96), respectively. The clinical outcomes of the patients showed concordance with reduction quality. The median operation duration was 180 minutes (range 125-270). Iatrogenic neurovascular damage was not noted in any patients. DISCUSSION: Reduction and fixation of deep intrapelvic fractures are risky and difficult due to the narrow anatomy and adjacent crucial neurovascular structures. As the 105-degree drill application is safe and easy to intervene in, short surgery duration and satisfactory results with minimum complications can be obtained with a 105 angulated drill in the deep pelvic region.

Fixation of bilateral acetabular fractures using the modified Stoppa approach: Two-year clinical outcomes.

OBJECTIVES: This study aims to evaluate the two-year clinical results of bilateral acetabular fractures operated via a single incision with the modified Stoppa approach. PATIENTS AND METHODS: Between January 2013 and January 2020, a total of 22 acetabular fractures of 11 patients (7 males, 4 females; mean age: was 42.9±13.7 years; range, 19 to 62 years) who were operated via the modified Stoppa approach were retrospectively analyzed. The medical records were analyzed in terms of time to surgery, fracture patterns, Injury Severity Score (ISS), operation duration, blood loss, reduction quality, perioperative complications and concomitant injuries. Reduction quality was assessed according to Matta's criteria. The Harris Hip Score (HHS) and modified Merle d'Aubigne score (MDS) were utilized for functional assessment. RESULTS: The mean follow-up was 49±15 (range, 30 to 79) months. The mean ISS was 28.2±7.2. The mean modified MDS was 15.90±1.57. The mean HHS was 84.27±8.85. For both sides, reduction was anatomical-anatomical (63.6%) in seven patients, anatomical-imperfect in three (27.3%) patients, and imperfectpoor in one (9.1%) patient. According to the Kellgren-Lawrence radiological evaluation at 24 months of follow-up bilaterally, Grade 0-1 osteoarthritis was observed in six (54.5%) patients, Grade 1-1 in four (36.4%) patients, and Grade 1-2 osteoarthritis in one (9.1%) patient. CONCLUSION: The modified Stoppa approach in bilateral acetabular fractures seems to be more preferable than other approaches, as it can be performed with a single incision and provides less bleeding, shorter operation duration, and satisfactory results.

Subacromial impingement as a predictor of proximal biceps tendon disorders.

OBJECTIVES: This study aims to investigate the relationship between proximal biceps tendon disorders and the degree of subacromial impingement in patients who underwent arthroscopic subacromial debridement. PATIENTS AND METHODS: Between January 2015 and June 2021, a total of 110 patients (44 males, 66 females; mean age: 52.5±11.43 years; range, 15 to 78 years) who underwent arthroscopic subacromial decompression were retrospectively analyzed. The degree of the subacromial impingement observed during arthroscopy was classified into four stages according to the Neer classification. We classified proximal biceps tendon disorders as five grades according to the Nirschl classification. The proportional relationship between subacromial impingement and biceps tendinopathy severity was analyzed. RESULTS: While biceps tendon degeneration was found to be significantly lower in patients with mild or no subacromial impingement, high rates of severe biceps tendon degeneration were observed in patients with high degree of subacromial impingement. A total of 75% of the patients who had no subacromial impingement had no biceps tendon disorder. Approximately 50% of the patients with Stage 1 subacromial impingement did not have biceps disorder, 31.3% had inflammation, and 12.5% had minor degeneration. In Stage 2 subacromial impingement group, the ratio of inflammation (42.9%) and minor degeneration (42.9%) of biceps tendon greatly increased, and the highest rate of biceps tendon degeneration was observed in the most advanced stage (Stage 3) subacromial impingement group (39.3%) (p=0.001). CONCLUSION: The stage of subacromial impingement is correlated with the degree of biceps degeneration. Therefore, one should keep in mind that the presence of advanced subacromial impingement may indicate advanced biceps tendon pathologies.

An Evaluation of the Fear of Falling, Balance Levels, and Prognostic Blood Parameters Among the Geriatric Population With Hip Fractures.

Background In this study, we determined that among patients who had been operated upon for hip fractures at our hospital, prognostic factors for mortality and functional recovery in the preoperative period were indicated via laboratory parameters using the International Falls Efficacy Scale (FES-I) and Berg Balance Scale (BBS) scores. Methodology Between January 2020 and January 2021, the results of 64 patients who had been surgically treated for a hip fracture and 57 patients who had scheduled elective surgery were compared retrospectively. The groups' demographic data and blood parameters were compared. We used the FES-I and BBS scores to determine patients' physical functional status and fear of falling. Results The case group's statistically significant FES-I score was high, and its BBS score was low (p = 0.001/0.001). As expected, the case group's D-dimer measurement was higher than the control group's (p = 0.001). In addition, hemoglobin, platelet, lymphocyte, albumin, total protein, and calcium levels were lower in the case group (p = 0.001 for all levels). No significant difference was found for other parameters. Conclusions The scales are used by physical therapy, neurology, and orthopedics professionals to evaluate the geriatric population's physical functional status and fear of falling. We believe prevention and cost-effective treatments for hip fractures can be achieved by determining geriatric patients' hemoglobin, platelet, lymphocyte, albumin, total protein, and calcium levels upon hospital admission and by directing these patients to relevant clinics using the fear-of-falling and balance scales.

Locking compression plate fixation versus intramedullary nailing of humeral shaft fractures: which one is better? A single-centre prospective randomized study.

PURPOSE: To compare the radiological and clinical outcomes of interlocking nail (ILN) and locking plate fixation (LCP) for humeral shaft fractures. METHODS: A total of 63 patients with displaced humeral shaft fractures between October 2014 and January 2017 were evaluated prospectively. They were divided randomly into two as LCP fixation (group 1) and interlocking nail (ILN) (group 2). Functional outcomes were evaluated using the Disabilities of the Arm, Shoulder, and Hand (DASH), American Shoulder and Elbow Surgeons (ASES), the University of California at Los Angeles (UCLA) shoulder scores, and Short Form-36 (SF-36) questionnaires, and pain was assessed with visual analogue scale (VAS). RESULTS: After fracture callus was radiologically observed, DASH, ASES, and UCLA scores as well as SF-36 questionnaires and VAS results were noted to have no significant difference between the two groups (p = 0.109, p = 0.082, p = 0.146, p = 0.322, and p = 0.175, respectively). At the last follow-up (post-operative 24 months), the UCLA score was significantly better in group 1 (p = 0.034), whereas VAS result was significantly worse in group 2 (p = 0.017). DASH, ASES scores, and SF-36 questionnaires had no difference (p = 0.193, p = 0.088, p = 0.289). Other parameters revealed no significant differences. Fracture consolidation was observed at a mean of four months in both groups (3 to 7 months in group 1 and 3 to 8 months in group 2) (p = 0.189). Four patients in group 1 and five patients in group 2 underwent surgery for nonunion (p = 0.725). Post-operative radial nerve palsy was seen in one patient in group 2. Two patients in group 1 with superficial infection were treated with antibiotics, and they recovered. CONCLUSIONS: Regarding our results, the LCP group had significantly better shoulder function than the ILN group, whereas the ILN group had significantly less pain, with similar complication rates. Therefore, both procedures are favourable surgical options for patients with humeral shaft fractures.

Joint line reestablishment in revision total knee arthroplasty.

BACKGROUND: In this study, the traditional "Anatomical Landmark-Distance Method (AL-DM)" in the formation of joint line (JL) was compared with "Adductor Tubercle-Ratios method" (AT-RM), and the effect of reestablishment of JL on clinical and functional outcomes were evaluated. MATERIALS AND METHODS: 16 revision total knee arthroplasties (rTKAs) were performed by using "AT-RM" (group 1) and 16 rTKA by using "AL-DM" (group 2) in our clinic between 2015 and 2018. The data were prospectively collected and a total of 32 knees of 31 patients were analyzed. At the final follow-up, knee functions were evaluated by using Knee Society Score (KSS) knee and function, Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores, Short Form-36 (SF-36) questionnaires and physical examinations. RESULTS: Postoperative flexion arc was higher in Group 1. KSS knee and function scores were better in group 1. In group1, JL was reestablished successfully in all revision rTKAs in terms of ATJL and the tibial tubercle TT-JL ratios. The improvement in KSS knee and function scores and WOMAC scores were also better in group 1. Measurements showed that the improvement in KSS scores increased as AT-JL and TT-JL distances approached the calculated values. CONCLUSION: "AT-RM" was shown to be superior to the traditional distance method in terms of JL reestablishment. Functional results and patient satisfaction increased when JL was reestablished.

Tranexamic acid in total knee replacement which protocol? which application form? A prospective randomised study.

The aim of this study was to prospectively compare different delivery forms, doses and combined application forms of TXA for the reduction of blood loss and prevention of the allogeneic blood transfusion in patients with TKA and evaluate the results. The study included patients with knee joint osteoarthritis who were unresponsive to conservative management and 168 patients met the inclusion criteria. They were divided into 5 groups randomly as, Control (1), Local (2), Systemic+short infusion (3), Systemic+long infusion (4) and Systemic+oral TXA (5). When compared with the Control group, blood loss was significantly reduced in Groups 2, 3 and 4 (p=0.001, 0.001, 0.003) but not in Group 5. Twenty- four hour drainage output was lower in all treatment groups (p=0.001, 0.001, 0.001, 0.004). Although TXA groups had no difference in terms of blood loss, 24- hour drainage outputs of the local TXA group were less than Group 4 and 5 and it yielded similar amounts in comparison with group 3. It was determined that TXA use whether local or systemic gave rise to decreased blood loss and prevent allogeneic blood transfusion. But, regarding the results above, local TXA seemed to have favorable effects when compared with systemic+long infusion and systemic+oral TXA usage, whereas local use had similar results with systemic+short infusion. Additionally, there found no difference between systemic+short, systemic+long infusion and systemic+oral combined TXA usage with respect to blood loss, transfusion rates and drain follow-up. We recommend further prospective randomized controlled studies to make clear these differences. Systemic+oral combined TXA use have promising results when compared with other systemic multiple deliveries.

The Effect of Pentoxifylline and Hyperbaric Oxygen on Achilles Osteotendinous Junction Injury: An experimental animal model study.

BACKGROUND: To investigate the effects of hyperbaric oxygen (HBO) and pentoxifylline (PTX) treatment on osteotendinous junction healing of Achilles tendon in an animal model. MATERIALS AND METHODS: Thirty-six adult female Wistar-albino rats were randomly divided into three groups as control, PTX and HBO groups with a total of 12 rats per group. Under general anesthesia, the Achilles tendons were cut at the level of the osteotendinous junction and repaired. After the surgery, no treatment was given to the control group. Fifty mg/kg intraperitoneal PTX was administered to the PTX group daily for 1 week. The HBO group was exposed to 2,5 atmospheric pressure, 100% oxygen for 2 hours daily for 1 week. All animals were sacrificed at the end of sixth week. Biomechanical tests and histological examinations were performed. RESULTS: Energy absorption was significantly higher in the PTX group than that in the control group after biomechanical tests (p=0.010). Histopathological evaluation results revealed no difference between the groups: however, hyalinization level was relatively better in the HBO group than that in the control group (p=0.026). CONCLUSIONS: 1. We concluded that PTX has a positive effect on the treatment of osteotendinous junction injuries based on our results. 2. Although HBO therapy did not provide statistically significant differences, it might have some positive effects on these injuries. 3. Further experimental studies and clinical trials should be conducted.
