Abstract
INTRODUCTION Neurovascular compromise following primary or revision total knee arthroplasty is a rare but severe complication. To the best of our knowledge, there have been reports of pseudoaneurysm of the popliteal artery following primary and revision; however, an anterior tibial artery pseudoaneurysm with articulating spacer has not been described yet. CASE PRESENTATION We introduce a rare case of anterior tibial artery pseudoaneurysm and concomitant foot drop caused by an articulating spacer in a two-stage revision for infected knee replacement. Displacement of the articular spacer was observed on knee x-rays. Hematoma and pseudoaneurysm were detected. The patient was operated on urgently, and a pseudoaneurysm originating from the anterior tibial artery was intraoperatively observed. DISCUSSION Vascular complications following TKA are rare but could be limb-threatening and even life-threatening. If postoperative displacement of the articulating spacer is observed with neurovascular symptoms, orthopedic surgeons should be alerted to the possibility of a pseudoaneurysm. CONCLUSION Although rare, anterior tibial artery pseudoaneurysm should be considered among vascular injuries in revision knee arthroplasty cases.

Abstract
OBJECTIVE Pes planovalgus is the most common foot deformity seen in patients with cerebral palsy (CP). There are several different treatment modalities to treat this condition. Single or double calcaneal osteotomies, extra-articular arthrodesis, calcaneo-cuboido-cuneiform osteotomy, intraarticular arthrodesis, and arthroereisis are some of these modalities. Currently, there is insufficient information to determine the most effective treatment approach for pes planovalgus in children with CP. The aim of this study is to show the short to mid-term results of the new technique which combines calcaneus lengthening osteotomy, extra-articular subtalar arthrodesis, and soft tissue reconstruction that aims to decrease recurrence and complication rates of pes planovalgus surgery for patients with ambulatory CP. METHODS Patients with CP who were treated with calcaneal lengthening surgery and extra-articular subtalar arthrodesis between 2018 and 2021 were investigated retrospectively. All patients were ambulatory and Gross Motor Function Classification System I-II-III. Functional levels of the patients were assessed with the American Orthopaedic Foot and Ankle Society, Ankle-Hindfoot Score, and the Foot and Ankle Ability Score (Foot and Ankle Ability Measure) in preoperative and postoperative periods. On anteroposterior x-rays, talus-first metatarsal, talocalcaneal, talonavicular coverage angle and on lateral x-rays talus-first metatarsal, talocalcaneal, calcaneal inclination angle and talar tilt angle were evaluated. RESULTS The mean follow-up was 46 (range: 36 to 60) months. The mean American Orthopaedic Foot and Ankle Society increased from 41 (20 to 79) to 74 (38 to 93; P < 0.001). The mean Foot and Ankle Ability Measure increased significantly from 35 (7 to 73) to 54 (29 to 96; P<0.001). Clinical results were "satisfactory" for 32 feet, while they were "unsatisfactory" for 2 feet. Significant deformity correction was observed in all radiologic parameters. CONCLUSION Our technique is found to be efficient for patients with Gross Motor Function Classification System I-II-III CP with pes planovalgus deformity. In short to mid-term follow-up, the technique achieved successful clinical and radiologic results with low complication rates. Superiority of this technique compared with the traditional ones can only be shown with randomized prospective studies. LEVEL OF EVIDENCE Level III-retrospective cohort study.

Abstract
This study aimed to test and compare the biomechanical properties of three tibial fixation methods of anterior cruciate ligament (ACL) tendon grafts under cyclic load and load-to-failure testing in the bovine proximal tibiae, comprising (1) staple fixation alone, (2) interference screw fixation alone, and (3) interference screw fixation with a supplementary staple. Twenty-four bovine tibiae used in the study were divided into three groups (eight proximal tibiae in each group) based on tibial fixation methods of ACL tendon grafts: group A (a spiked ligament staple alone), group B (a cannulated interference screw alone), and group C (a cannulated interference screw with a supplementary staple). Each graft fixation was exposed to cyclic loading conditions. Significant differences were determined in failure load among the three groups (p = 0.008). The mean failure load was significantly higher in group B (717.04 ± 218.51 N) than in group A (308.03 ± 17.22 N) (p = 0.006). No significant differences were observed among the groups regarding axial stiffness (p = 0.442). Cyclic displacement differed significantly among the three groups (p = 0.005). In pairwise comparisons, the mean cyclic displacement was significantly higher in group A (8.22 ± 3.24 mm) compared with group C (1.49 ± 0.41 mm) (p = 0.005). Failure displacement varied considerably among the groups (p = 0.037). Although group B (15.53 ± 6.43 mm) exhibited a greater mean failure displacement than both group A (4.9 ± 0.75 mm) and group C (8.84 ± 4.65 mm), these differences did not reach statistical significance (p = 0.602 and p = 0.329, respectively). Interference screw fixation alone and supplementary staple fixation have biomechanically similar characteristics in terms of initial strength and stiffness of tibial ACL soft tissue graft fixation. Regardless of staple use, an interference screw with the same diameter as the tibial tunnel can ensure sufficient tensile strength in tibial ACL graft fixation.

Abstract
OBJECTIVE The aim of this study was to biomechanically compare a new lateral-pinning technique, in which pins engage the medial and lateral columns of the distal humerus in a divergent configuration in both the axial and sagittal planes instead of the coronal plane, with the cross-pin, and with 2 and 3 coronally divergent lateral-pin techniques in a synthetic humerus model of supracondylar humerus fractures. METHODS Thirty-six identical synthetic models of the humerus simulating a standardized supracondylar humerus fracture were included in this study. They were divided into 4 groups based on the pin configuration of fixation: the new 3-lateral pin-fixation technique (group A), 2 crossed pins (group B), 3 divergent lateral pins (group C), and 2 divergent lateral pins (group D). Each model was subjected to combined axial and torsional loading, and then torsional stability and torsional stiffness (Nmm/°) were recorded. RESULTS Group A had greater rotational stability than groups C and D but had no statistically significant additional rotational stability compared with group B (P=.042, P=.008, P=.648, respectively), whereas group B had greater rotational stability than only group D (P=.020). Furthermore, group A demonstrated higher internal rotational stiffness compared with groups C and D (P=.038, P=.006, respectively). Group B had better internal rotational stiffness than group D (P=.015). There was no significant difference in internal rotational stiffness between groups A and B (P=. 542), groups B and C (P=.804), and groups D and C (P=.352). Although no statistically significant differences existed between groups A and B, the modified pin configuration exhibited the highest torsional stability and stiffness. Group D showed the lowest values in all biomechanical properties. CONCLUSION This study has shown us that this new lateral-pinning technique may provide torsional resistance to internal rotational displacement as strong as the standard technique of crossed-pin configuration of fixation. Furthermore, with this new pin configuration, greater torsional resistance can be obtained than with either the standard 2- or the standard 3-lateral divergent pin configuration.

Abstract
Mueller-Weiss Syndrome (MWS), characterized by spontaneous adult-onset tarsal navicular osteonecrosis, is an uncommon cause of chronic midfoot pain that can lead to functional impairment and progressive deformities. This study aimed to present clinical and radiological outcomes of talonavicular-cuneiform (TNC) arthrodesis in the treatment of patients with MWS. A retrospective study was performed on 8 consecutive patients (6 female, 2 male; mean age = 50 years; range = 33-64) who underwent TNC arthrodesis using plate fixation with autologous bone grafting for the treatment of MWS. To evaluate clinical status, the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Midfoot Score was performed immediately preoperatively and at the final follow-up. In radiographic evaluation, talus-first metatarsal angle (Meary's angle) was measured preoperatively and at the final follow-up. Solid fusion was also examined on postoperative radiographs and computerised tomography. The mean follow-up was 35 months (range = 24-52). The mean AOFAS improved from 37 (range = 24-53) preoperatively to 85 (range = 80-93) at the final follow-up (p < 0.001). No major intra- operative complications were observed in any of the patients. According to the Maceira and Rochera radiological staging system, 5 feet was stage 3, and 3 feet was stage 4. The mean union time was 10 months (range = 5-15). Radiographic solid fusion was achieved in all but one foot that developed talonavicular non-union. TNC arthrodesis using plate fixation with autologous bone grafting seems to be an effective surgical method for reconstruction of MWS.

Abstract
The effect of osteotomy type on the initial stiffness of the bone-implant construct in lateral opening-wedge distal femoral osteotomy (LOWDFO) using a uniplanar compared with a biplanar technique has been investigated. However, no study has explored the biomechanical risk factors for medial hinge fracture. This study aimed to compare the biomechanical strength of uniplanar versus biplanar LOWDFO regarding the risk for medial hinge fracture during gap opening. Twelve composite femora were divided into two groups (six in each group) based on the distal femoral osteotomy technique: uniplanar versus biplanar LOWDFO. All LOWDFO models were subjected to incremental static loading. The gap distance was expanded by 1 mm, and displacement values were recorded as anterior and posterior gap distances (mm). The average force values of all samples at certain gap distances were recorded, and the head distance was measured. The uniplanar group had higher load values than the biplanar group at all anterior gap distances. These differences were only significant at 2- and 3-mm gap distances (p = 0.025 and 0.037). At all posterior gap distances, the uniplanar group had higher load values than the biplanar group, but these differences only reached statistical significance at 2 mm (p = 0.037). Both groups had similar anterior, posterior, and average gap distances (p = 0.75, 0.522, 0.873). The uniplanar group had a higher head insertion distance (15.3 ± 5.7) than the biplanar group (14.7 ± 2.9), but it was not significant (p = 0.87). The uniplanar group had a lower average load before medial hinge fracture (46.41 ± 13.91 N) than the biplanar group (54.92 ± 31.94, p = 0.81). The biplanar group had an average maximum load value of 64.18 ± 25.6 N, while the uniplanar group had 57.90 ± 12.21 N (p = 0.81). This study revealed that the biplanar osteotomy technique allows a wider opening wedge gap with less risk of a medial hinge fracture than uniplanar LOWDFO.Level of evidence was level 3, case-control series.

Abstract
Background Ankle fractures constitute 10% of all traumatic fractures in clinical practice. Concurrent tibiotalar dislocations form 21-36% of all ankle fractures. Although mechanism of injury is similar to non-dislocated ankle fractures, fracture-dislocations cause more extensive bone and soft tissue damage. Treatment is a challenge for orthopedic surgeons due to concomitant pathologies. It is associated with malreduction, chronic pain and most importantly, posttraumatic osteoarthritis. We aimed to investigate the relationship between ankle osteoarthritis radiographic stage and clinical outcomes. Methods 27 patients (17 female, 10 male) were included in the study. Records and data were retrospectively analyzed. Clinical status at the final follow-up was evaluated by a single orthopedic surgeon. Range of motion (ROM), American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score, visual analogue scale (VAS) were the clinical parameters that were assessed. Radiological assessment was made by standard anteroposterior [AP], lateral, and mortise views. Pre-operative osseo-ligamentous injury pattern, presence of posterior malleolar fracture, syndesmosis injury and post-operative ankle osteoarthritis were investigated. Results For 27 patients that were evaluated, at the final follow-up, mean AOFAS was 85 ± 8.12, and mean VAS during daily activities was 1.52 ± 0.70. Mean ankle dorsiflexion and plantar flexion were significantly lower on the affected sides (14.07 ± 7.97° and 36.30 ± 6.59°) than on the unaffected sides (28.15 ± 2.82° and 46.30 ± 2.97°), respectively (p < 0.001). No significant difference for inversion and eversion was observed. Twenty-four patients demonstrated radiographic signs of ankle osteoarthritis, and three remained without evidence of osteoarthritis. No significant difference was found among Takakura's stages in any of the variables. Conclusion The results illustrated that although post-traumatic osteoarthritis rate was high for ankle fracture-dislocation patients, surgical treatment achieved excellent functional results. Even if advanced stages of ankle arthritis according to Takakura's classification developed, patients had satisfactory clinical and functional results.

Abstract
Pneumonia, a respiratory disease often caused by bacterial infection in the distal lung, requires rapid and accurate identification, especially in settings such as critical care. Initiating or de-escalating antimicrobials should ideally be guided by the quantification of pathogenic bacteria for effective treatment. Optical endomicroscopy is an emerging technology with the potential to expedite bacterial detection in the distal lung by enabling in vivo and in situ optical tissue characterisation. With advancements in detector technology, optical endomicroscopy can utilize fluorescence lifetime imaging (FLIM) to help detect events that were previously challenging or impossible to identify using fluorescence intensity imaging. In this paper, we propose an iterative Bayesian approach for bacterial detection in FLIM. We model the FLIM image as a linear combination of background intensity, Gaussian noise, and additive outliers (labelled bacteria). While previous bacteria detection methods model anomalous pixels as bacteria, here the FLIM outliers are modelled as circularly symmetric Gaussian-shaped objects, based on their discrete shape observed through visual analysis and the physical nature of the imaging modality. A Hierarchical Bayesian model is used to solve the bacterial detection problem where prior distributions are assigned to unknown parameters. A Metropolis-Hastings within Gibbs sampler draws samples from the posterior distribution. The proposed method's detection performance is initially measured using synthetic images, and shows significant improvement over existing approaches. Further analysis is conducted on real optical endomicroscopy FLIM images annotated by trained personnel. The experiments show the proposed approach outperforms existing methods by a margin of +16.85% ( F1 ) for detection accuracy.

Abstract
PURPOSE The study aimed to evaluate preliminary clinical and radiographic results of patients with Cierny-Mader type IV chronic femoral osteomyelitis and augmented with a non-vascularized fibular autograft as a salvage procedure because of the poorly regenerated new bone after bone transport over an intramedullary nail (BTON). METHODS Patients diagnosed with CM type IV chronic femoral bone infection and treated with BTON procedure between 2003 and 2020 were retrospectively reviewed. Seven patients were included in the study whose distraction gap was poorly regenerated and then augmented with a non-vascularized fibular autograft. A three-stage treatment was administered. First, the infection was eradicated. Second, BTON was performed. Third, the poorly regenerated distraction gap was augmented with a fibular autograft before removing the external fixator (EF). Clinical and radiological results were evaluated based on the criteria described by Paley-Maar and Li classification. RESULTS The mean patient age was 52 years. The mean treatment time was 24.8 months, with a mean femoral lengthening of 12.6 cm. The mean EF and bone healing indexes were 0.57 months/cm and 0.8 months/cm, respectively. The mean length of the fibular graft was 13 cm. The bone healing of new bones was achieved in all patients with good quality after grafting. Functional scores were excellent in four patients. No patients experienced any sequelae. CONCLUSIONS Non-vascularized fibular autograft augmentation may be an effective salvage procedure for poorly regenerated new bone after BTON to manage chronic femoral bone infection.

Abstract
Background: This study aimed to evaluate our preliminary results and experience with the arthroscopic dorsal ligamentocapsulodesis in managing occult dorsal wrist ganglion cysts (ODGCs) associated with scapholunate (SL) instability. Methods: All patients who underwent arthroscopic dorsal ligamentocapsulodesis due to an ODGC with concomitant SL ligament tear were retrospectively reviewed. In addition to demographic data and length of follow-up, outcomes data that included range of motion, grip strength, modified Mayo wrist score (MMWS), complications and radiographs were collected. Results: The study included 18 patients (18 wrists; 10 female and 8 male). The mean age was 32 years (range: 19-48) and the mean follow-up was 34 months (range: 24-48). The mean preoperative extension deficit decreased from 5.5° (range: 0°-20°) to 2.7° (range: 0°-15°) at the final follow-up (p = 0.004). The mean preoperative flexion deficits decreased from 4.4° (range: 0°-15°) to 2.2° (range: 0°-10°) postoperatively (p = 0.003). The mean hand grip strength significantly increased from 27.7 kg (range: 22-36) to 38.3 kg (range: 31-46) at the final follow-up assessment (p < 0.001). The mean MMWS improved from 46 (range: 25-65) pre-operatively to 91 (range: 70-100) at the final follow-up (p = 0.0002). No major intra- or postoperative complications were observed. Conclusions: SL instability may have an important role in the aetiology of ODGCs, and arthroscopic dorsal ligamentocapsulodesis can provide pain relief and functional improvement without recurrence at the short- to mid-term follow-up in the treatment of ODGCs. Level of Evidence: Level IV (Therapeutic).

Comparison of sinus tarsi approach versus extensile lateral approach in the management of displaced intra-articular calcaneal fractures: A single-center study. ULUS TRAVMA ACIL CER 2023; 29:1061-1067. [PMID: 37681728 PMCID: PMC10560813 DOI: 10.14744/tjtes.2023.13642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 08/06/2023] [Accepted: 08/14/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND Controversy still exists for optimal treatment for displaced intra-articular calcaneal fractures (DIACFs). Conven-tionally, the extensile lateral approach (ELA) has been the most preferred approach. Although ELA provides excellent fracture access and direct evaluation of the depressed posterior facet, this approach has a high rate of serious complications, such as hematoma, superficial/deep infection, and wound healing issues. To overcome such complications, more minimally invasive techniques including external fixation, percutaneous fixation, arthroscopic assisted fixation, and sinus tarsi approach (STA) have been recently described. The primary aim of this study was to compare STA and LEA in the treatment of DIACFs. METHODS Patients who were operated for DIACFs in our clinic were included in the study. Patients with closed DIACFs of Sanders Type II, III, IV, and over 18 years of age were identified. Physical examinations and radiological evaluations of the patients were per-formed, and clinical scores were filled. Patients were divided into subgroups according to the Sander's classification and comparisons were made again according to these subgroups. RESULTS There were 37 patients (four female and 33 male) in STA group and 44 patients in LEA group (six female and 38 male). The mean age was 44.42±13.57 years (range, 18-61) for STA group and 37.32±11.09 years (range, 18-56) for the LEA group. In clinical outcomes, except for short-form survey (SF-12)/MCS-12 (Mental Score) and visual analog scale score, all the parameters were signifi-cantly better in STA group compared to LEA group. No significant difference was observed between the two groups in radiographic results, except for the Böhler angle. Significantly less infection occurred in the STA group compared to LEA group (P=0.021). According to Sander's classification, American Orthopedic Foot and Ankle Society, foot and ankle disability index, and SF-12/PCS-12 and foot function index scores, no significant differences were determined between STA and LEA groups for Sanders Type 2, whereas the values were considerably higher in STA group than in LEA group for Sanders Type 3 and 4. CONCLUSION In DIACFs, STA is considered a safe and effective method for restoring the width, height, and length of the calca-neus and reconstruction of joint alignment and has now become our standard technique for all calcaneal fractures requiring operative treatment.

Abstract
The Dias-Tachdjian classification is the most commonly used system for the classification of pediatric ankle fractures, but its inter- and intra-observer reliability has not been studied in detail. Also, the impact of the clinician's experience and expertise on the reliability of this system is unknown. This study aimed: (1) to determine the intra- and inter-observer reliability of the Dias-Tachdjian classification and (2) to investigate the effect of the clinician's experience and expertise on the reliability of this system. Anteroposterior and lateral ankle radiographs of 56 children (34 male, 22 female) with ankle fractures, aged between 3 and 14 years, with open growth cartilages, were retrospectively identified and included in the study. Each patient radiograph was examined by 10 observers from two different specialties with different levels of clinical experience (two orthopedic surgeons with interest in pediatric orthopedics, three orthopedic surgeons with no interest in pediatric orthopedics, three orthopedic residents, and two radiology specialists) from two different specialties (orthopedics and radiology). All observers were then asked to classify pediatric ankle fractures at 6-week intervals per the Dias-Tachdjian classification system. Overall, intra-observer reliability as substantial to very good (κ = 0.77-0.95, P < 0.01), but inter-observer reliability as fair for both assessments (κ = 0.21, P < 0.01 and κ = 0.20, P < 0.01 for the first and second occasions, respectively). Inter-observer reliability among pediatric orthopedic surgeons as very good (κ = 0.90, 95% CI = 0.86-0.94, P < 0.01 and κ = 0.82, 95% CI = 0.71-0.93, P < 0.01 for the first and second occasions, respectively). Orthopedic surgeons with no special interest in pediatric orthopedics demonstrated substantial agreement in the first occasion (κ = 0.63, 95% CI = 0.53-0.72, P < 0.01) but moderate in the second one. Orthopedic residents exhibited moderate levels of agreement in each assessment period (κ = 0.58, 95% CI = 0.47-0.68, P < 0.01 and κ = 0.44, 95% CI = 0.37-0.51, P < 0.01 for the first and second occasion, respectively). Considering that the specialists dealing with pediatric orthopedics show very good consistency for Dias-Tachdjian classification, both within and between observers, consistency in the identification of the ankle fracture models increases as the interest in the field of pediatric orthopedics intensifies.

[PMID: 37194040 DOI: 10.1186/s12891-023-06507-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Accepted: 05/10/2023] [Indexed: 05/18/2023] Open
Abstract
BACKGROUND It has been suggested that the posterior tibial slope (PTS) plays an important role in increasing the anteroposterior stability following total knee arthroplasty. Although the relationship between the PTS and the flexion range has been investigated many times, studies on the relationship between PTS and anterior-posterior stability are limited. The primary aim of this study was to investigate the relationship and effects of PTS on anteroposterior stability in posterior cruciate retainer total knee arthroplasty. METHODS 154 primary TKAs were identified retrospectively to analyze the any association between PTS and anteroposterior laxity following posterior cruciate-retaining total knee arthroplasty in the overall study populations. Anteroposterior displacement was measured at the final follow-up based on the following two procedures: KT-1000 arthrometer and sagittal drawer radiographic images. In addition, the relationship between PTS and functional scores-ROM was examined. RESULTS There was no correlation between patients' posterior tibial slope and postoperative VAS (r: -0.060, p:0.544), WOMAC (r:0.037, p:0.709), KSS (r: -0.073, p:0.455). In addition, there was no significant correlation between postoperative knee ROM and postoperative PTS (r:0.159, p:0.106). Moreover, no correlation was found between KT-1000 arthrometer and 20 degrees AP translation with PTS. There was a negative correlation between PTS and 70 degrees AP translation (r: -0.281, p:0.008). CONCLUSIONS This study aimed to clarify the association between instability and AP laxity in flexion of implanted knees, and to determine what degree of AP laxity results of instability. A fundamental finding of this study was that; the optimum TS angle to increase anterior-posterior stability after total knee arthroplasty is between ≥ 4 to < 6 degrees, we also proved that there is no relationship between stability and patient satisfaction.

J Wrist Surg 2023; 12:113-120. [PMID: 36926214 PMCID: PMC10010898 DOI: 10.1055/s-0042-1751078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Accepted: 05/24/2022] [Indexed: 10/17/2022]
Abstract
Introduction The literature is scarce regarding the management of combined tears of scapholunate (SL) and lunotriquetral (LT) ligaments. This study aimed to evaluate our preliminary results with the arthroscopic dorsal ligamentocapsulodesis in managing such cases. Materials and Methods Forty-two patients (13 females, 29 males; mean age = 31; age range = 18-51 years) who underwent arthroscopic dorsal ligamentocapsulodesis due to the combined tears of SL and LT ligaments were retrospectively reviewed. The mean follow-up was 38 (range = 24-55) months. The Modified Mayo Wrist Score, the visual analogue scale (VAS), and grip strength were assessed preoperatively and at the final follow-up examination. Results The mean Modified Mayo Wrist Score significantly improved from 49 (range = 25-70) preoperatively to 82 (range = 60-100) at the final follow-up ( p = 0.000). The mean VAS significantly decreased from 6.33 to 1.6 ( p = 0.000). The mean hand grip strength significantly improved from 31 (range = 19-41) kg to 44 (range = 25-60) kg at the final follow-up examination ( p < 0.001). No major complications were encountered. Conclusion Arthroscopic dorsal ligamentocapsulodesis seems to be a safe and effective surgical technique in the management of this rare combined injury pattern. Level of Evidence This is a Level IV, retrospective case series study.

Fabrication of hydroxyapatite-based nano-gold and nano-silver-doped bioceramic bone grafts: Enhanced mechanostructure, cell viability, and nuclear abnormality properties. J Biomed Mater Res B Appl Biomater 2023; 111:1386-1397. [PMID: 36891913 DOI: 10.1002/jbm.b.35242] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 02/10/2023] [Accepted: 02/23/2023] [Indexed: 03/10/2023]
Abstract
In this study, nano-gold (nAu) and nano-silver (nAg) were doped at the molar ratios of Molar5-Molar30 to the Hydroxyapatite (HAp)-based bioceramic bone graft synthesized by the sol-gel method. The effects of nAu and nAg on structural, mechanical, cell viability, and nuclear abnormality of the synthesized bioceramic grafts were evaluated. The chemical and morphological properties of the bone grafts after production were examined through XRD and SEM-EDX analyses and mechanical tests. To determine the biocompatibility of the bone grafts, cell viability tests were performed using human fibroblast cells. In the cytotoxicity analyses, only HAp and HAp-nAu5 grafts did not show toxicological properties at any concentration, while HAp-nAg5 among the nAg-containing grafts gave the best results at the 200-100 μg/mL concentrations and showed significant cytotoxicity in human fibroblast cells. The other nAu-containing grafts showed toxicological properties in the concentration range of 200-50 μg/mL and nAg-containing grafts in the concentration range of 200-100 μg/mL against the negative control. The micronucleus (MN) analyses showed that the lowest total MN and L (lobbed) amounts, while the lowest total N (notched) amount, was obtained from the only HAp graft. It was found that the nAg-doped bone grafts gave higher total MN, L, and N amounts compared to the nAu-doped bone grafts. Furthermore, while the mean nuclear abnormality (NA) values of all grafts gave close results, the highest values were again obtained from the nAg-doped bone grafts.

Abstract
OBJECTIVE Although the therapeutic efficacy of conventional core decompression (CD) for the early-stage osteonecrosis (ON) has been widely investigated in the literature, no study to date has specifically focused on its therapeutic effect on the long-term outcome of ON of the femoral head (ONFH) in systemic lupus erythematosus (SLE). This study aimed to provide a long-term survival analysis of all hips that underwent conventional CD for the management of ONFH in a consecutive case series of patients with SLE. PATIENTS AND METHODS Sixteen hips of 10 consecutive SLE patients that underwent conventional CD for the management of ONFH in a single tertiary referral center were retrospectively identified and included in the study. After a retrospective chart review, several clinical and radiological data were recorded. RESULTS All the hips treated with CD were stage I or IIA sclerotic and/or cystic based on the classification system of Ficat. Only the 2 hips of 1 patient (12.5%) survived both clinically and radiographically. The median overall survival for all hips after CD was 80 months (95% CI, 60-100). The 5-, 10-, and 15- year survival rates of hip joints following CD were 63%, 31%, and 12.5%, respectively (CI 95% 63.567 to 133.058 months). CONCLUSIONS Conventional CD may not be effective in preventing the progression of pre-collapse ONFH to collapse and eventually end-stage osteoarthritis requiring arthroplasty in patients with SLE.

Acute monoarthritis in children: clinical and laboratory factors distinguishing septic arthritis from noninfectious inflammatory arthritis. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2023; 27:1278-1287.

Abstract
OBJECTIVE Distinguishing septic arthritis from specific inflammatory arthritis in children with acute monoarthritis can be a clinical challenge. This study aimed to assess the diagnostic performance of presenting clinical and laboratory findings for distinguishing septic arthritis from common forms of noninfectious inflammatory arthritis in children with acute monoarthritis. PATIENTS AND METHODS Children presented for the first episode of monoarthritis were retrospectively reviewed and then divided into two groups: (1) the septic group, 57 children with true septic arthritis, and (2) the non-septic group, 60 children with several types of noninfectious inflammatory arthritis. Several clinical findings and serum inflammatory markers on admission were documented. RESULTS Univariate analyses demonstrated that body temperature, weight-bearing status, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cell count (WCC), absolute neutrophil count (ANC), and neutrophil percentage (NP) levels were significantly higher in the septic group than in the non-septic group (p<0.001 for each variable). Based on the ROC analysis, optimum diagnostic cut-off values were 63 mg/L for CRP, 6,300/mm3 for ANC, 53 mm/h for ESR, 65% for NP, 37.1°C for body temperature, and 12,100/mm3 for WCC. While children with no presenting factor had a 4.3% risk of having septic arthritis, those with six predictors had a risk of 96.2%. CONCLUSIONS A CRP level of ≥63 mg/L is the best independent predictor of septic arthritis among the commonly used serum inflammatory markers (ESR, WCC, ANP, NP). It should be borne in mind that a child with zero predictors may still have a 4.3% risk of septic arthritis. Thus, clinical assessment is still imperative in managing children presenting with acute mono-arthritis.

Abstract
OBJECTIVE The first-line treatment for radial tunnel syndrome is conservative despite limited evidence concerning its efficiency. Surgical release is indicated if nonsurgical measures fail. Radial tunnel syndrome cases may be misdiagnosed as the more common lateral epicondylitis, and misdiagnosing radial tunnel syndrome causes wrong treatment and, thus, the perpetuation or increase of the pain. Although radial tunnel syndrome is a rare disorder, such cases can be encountered in tertiary hand surgery centers. This study aimed to present our experience in diagnosing and managing patients with radial tunnel syndrome. MATERIAL AND METHODS Eighteen patients (7 male, 11 female; mean age=41.5 years, age range=22-61) in whom radial tunnel syndrome was diagnosed and treated at a single tertiary care center were retrospectively reviewed and included. Previous diagnoses (wrong diagnosis, delayed diagnosis, missed diagnosis, and other), previous treatments for such diagnoses, and their results before presenting to our institution were recorded. The shortened disabilities of the arm, shoulder, and hand questionnaire score and visual analog scale score were recorded before the surgery and at the final follow-up appointment. RESULTS All the patients included in the study underwent steroid injections. Eleven patients (11/18, 61%) benefited from steroid injection and conservative treatment. The remaining 7 patients refractory to conservative treatment were offered surgical treatment. Of these, 6 patients accepted surgery while 1 did not accept it. In all patients, the mean visual analog scale score significantly improved from 6.38 (range: 5-8) to 2.1 (range: 0-7) (P < .001). The mean quick-disabilities of the arm, shoulder, and hand questionnaire scores were significantly improved from 43.4 (range: 31.8-52.5) preoperatively to 8.7 (range: 0-45.5) at the final follow-up (P < .001). In the surgical treatment group, the mean visual analog scale score significantly improved from 6.1 (range: 5-7) to 1.2 (range: 0-4) (P < .001). The mean quick-disabilities of the arm, shoulder, and hand questionnaire scores were significantly improved from 37.4 (range: 31.2-45.5) preoperatively to 4.7 (range: 0-13.6) at the final follow-up (P < .001). CONCLUSION Our experience has shown that satisfactory results can be obtained by surgical treatment for patients with radial tunnel syndrome refractory to nonsurgical treatment whose diagnosis is confirmed by a thorough physical examination.

Abstract
BACKGROUND Although tarsal coalition represents the most common cause of peroneal spastic flatfoot, its existence cannot be verified in several cases. In some patients with rigid flatfoot, no cause can be detected after clinical, laboratory, and radiologic examination, and the condition is called idiopathic peroneal spastic flatfoot (IPSF). This study aimed to present our experience with surgical management and outcomes in patients with IPSF. METHODS Seven patients with IPSF, who were operated on between 2016 and 2019, and followed for at least 12 months were included, whereas those with known causes, such as tarsal coalition or other causes (eg, traumatic) were excluded. All patients were followed up for 3 months with botulinum toxin injection and cast immobilization as a routine protocol, and clinical improvement was not achieved. The Evans procedure and grafting with tricortical iliac crest bone graft in five patients and subtalar arthrodesis in two patients were performed. The American Orthopaedic Foot and Ankle Society ankle-hindfoot scale scores and Foot and Ankle Disability Index scores were obtained preoperatively and postoperatively from all patients. RESULTS On physical examination, all feet manifested rigid pes planus with varying degrees of hindfoot valgus and limited subtalar motion. Overall, the mean American Orthopaedic Foot and Ankle Society and Foot and Ankle Disability Index scores significantly increased from 42 (range, 20-76) and 45 (range, 19-68) preoperatively (P = .018) to 85 (range, 67-97) and 84 (range, 67-99) (P = .043) at the final follow-up, respectively. No major intraoperative or postoperative complications were observed in any of the patients. All computed tomographic and magnetic resonance imaging scans revealed no evidence of tarsal coalitions in any of the feet. All radiologic workups failed to demonstrate secondary signs of fibrous or cartilaginous coalitions. CONCLUSIONS Operative treatment seems to be a good option in the treatment of patients with IPSF who do not benefit from conservative treatment. In the future, it is recommended to investigate the ideal treatment options for this group of patients.

Biomechanical comparison of four different fixation methods in the management of Pauwels type III femoral neck fractures: Is there a clear winner? Injury 2022; 53:3124-3129. [PMID: 35803747 DOI: 10.1016/j.injury.2022.06.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Revised: 06/18/2022] [Accepted: 06/22/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND Cannulated screws augmented with the medial buttress plate could confer greater biomechanical stability and higher union rates than the screw fixation alone for treating young patients with Pauwels type III femoral neck fractures (FNFs). No study has evaluated the effects of distal bicortical screw fixation and biomechanical properties of buttress plate augmentation under simultaneous vertical and rotational forces, physiologically acting on the hip joint. This study aimed to compare the biomechanical properties of four methods of three cannulated screw fixation under the combined axial and torsional loading in a synthetic femur model of type III FNF. METHODS Twenty-four third-generation composite femora were divided into four groups (6 femora in each group) based on the screw fixation configuration: inverted triangle configuration (Group A), Pauwels' configuration (Group B), inverted triangle configuration combined with medial buttress plate using distal unicortical (Group C), and distal bicortical screw placement (Group D). A Pauwels type III FNF was simulated on the sawbones. Each model was subjected to the combined axial and torsional cyclic loading and subsequently tested to failure. RESULT Significant differences were determined in axial stiffness (AS) among the four groups (p = 0.024), whereas there was no significant difference in torsional stiffness (p = 0.147). The mean AS was higher in group D (639.5 ± 86.2 N/mm) than in group A (430.6 ± 94.8 N/mm), group B (426.2 ± 41.9 N/mm), and group C (451.2 ± 156.7 N/mm). Failure forces (FFs) were significantly different among four groups (p = 0.007), while there was no considerable difference in failure moment values (p = 0.555). The mean FF was significantly higher in group D (1307.1 ± 96.4 N) than in group A (1076.9 ± 371.2 N) and group B (1075.5 ± 348.3 N) (p = 0.014 and p = 0.018, respectively). There was no significant difference in the mean FF between groups D and C. CONCLUSION Regardless of the medial plate use, multiple cannulated systems could provide similar biomechanical results regarding torsional stiffness and failure moments. Bicortical placement of the most distal screw in medial buttress plate application could improve axial stability but not significantly affect the rotational stability of the inverted triangle screw fixation system in managing type III FNFs.

Abstract
BACKGROUND Many authors have highlighted the role of muscle strength imbalance around the ankle in the development of recurrent clubfoot following Ponseti treatment. However, this possible underlying mechanism behind recurrence has not been investigated sufficiently to date. This study aimed to explore whether there is a relationship between Achilles tendon elongation and recurrent metatarsus adductus deformity in children with unilateral clubfeet treated by the Ponseti method. METHODS A retrospective chart review was performed on 20 children (14 boys and six girls; mean age, 7 years; age range, 5-9 years) with a recurrent metatarsus adductus deformity treated by the Ponseti method for unilateral idiopathic clubfoot. At the final follow-up, isometric muscle strength was measured using a portable, hand-held dynamometer in reciprocal muscle groups of the ankle. The length of the tendons around the ankle was measured ultrasonographically. RESULTS The plantarflexion-to-dorsiflexion ratio was lower on the involved side (P = .001). No significant differences in the strength ratio of inversion to eversion were found (P = .4). No difference was observed in lengths of tibialis anterior and posterior tendons (P = .1), but the Achilles tendon was longer on the involved side (P = .001; P < .01). A significant negative correlation was discovered between involved-to-uninvolved Achilles tendon length ratios and involved-to-uninvolved plantarflexion strength ratios (r = -0.524; P = .02) Conclusions: Achilles tendon elongation may be a contributor to the muscle imbalance in clubfeet with relapsed forefoot adduction treated by the Ponseti technique.

Abstract
Background: The literature is scarce regarding isolated tears of lunotriquetral interosseous ligament (LTIL). The purpose of this study was to present mid-term clinical and functional results of arthroscopic dorsal ligamentocapsulodesis in the treatment of isolated LTIL tears. Methods: Twenty-two patients (8 females, 14 males; mean age: 31 years; age range: 18-42) with isolated LTIL tears verified by wrist arthroscopy were retrospectively reviewed and included in the study. The mean follow-up was 55 months (range: 24-84). The modified Mayo wrist score, visual analog scale (VAS), flexion and extension deficits of passive wrist range of motion (ROM), pain-free ROM with forced wrist extension and grip strength were measured in all patients preoperatively and at final follow-up. Results: The mean modified Mayo wrist score significantly improved from 50 ± 10.29 preoperatively (range: 30-65) to 86 ± 11.61 (range: 60-100) at the final follow-up (p < 0.001). The mean VAS score significantly improved from 7.1 ± 0.83 (range: 6-8) preoperatively to 2.2 ± 1.35 (range: 0-6; p < 0.001) at the final follow-up. At the final follow-up examination, the forced wrist extension was painless in all but three patients who developed pain at 70º, 75º and 80º of extension, respectively. The mean strength of hand grip significantly increased from 38.6 ± 9.68 (range: 24-54) kg to 49.5 ± 12.36 (range: 33-66) kg at the final assessment (p < 0.001). No major complications were observed during or after the procedure. Conclusions: With the encouraging mid-term outcomes and a lower complication rate, arthroscopic LTIL dorsal ligamentocapsulodesis seems to be a safe and effective surgical technique in improving functional outcomes and reducing pain in patients with isolated LTIL tears. Level of Evidence: Level IV (Therapeutic).

Abstract
OBJECTIVE The aim of this study was to analyse the factors that led to resignations from Orthopaedics and Traumatology Residency pro- grammes in Turkey, and to determine the overall rate of resignation among residents from Orthopaedics and Traumatology programmes. METHODS In this cross-sectional survey,120 residents who either resigned or transferred to other OT clinics between autumn of 2013 and spring of 2020 were included. They were asked to complete a questionnare which was sent via Whatssapp application or e-mail. The ques- tionnare was comprised of 2 sections; Section A, which adressed resignation, consisted of 15 questions and Section B, which adressed transfer to another OT programme, consisted of 12 questions. Both sections had open ended and multiple choice questions. RESULTS Of 120 residents, 96 (6.6%) resigned and then transferred to another specialty, and 24 (1.6%) transferred to another orthopedics and traumatology clinic based on our review. The overall resignation rate as per the total quotas for orthopedics and traumatology residency from 2013 to 2020 was 8.2%. Of the 120 orthopedics and traumatology residents who were eligible for the survey, 83 (70%) completed the questionnaire. Sixty-one (60 males, 1 female; median age = 26 years; age range = 25-35) of 96 residents who resigned from the orthopedics and traumatology residency completed section A (the response rate was 63.5%); 22 (22 males; median age=27.6 years; age range=25-34) out of 24 residents who transferred to another orthopedics and traumatology clinic completed section B (the response rate was 91.6%). In section A, 40 out of 61 individuals (65.5%) preferred orthopedics and traumatology specialty as the first choice in TUS, and 34 residents (55.7%) reported not to have had enough information regarding the residency program before starting their clinics. In section B, out of the 22 residents, 13 (59%) stated that orthopedics and traumatology residency was not their first choice in TUS, and 18 (81.8%) reported not to have had sufficient knowledge about the preferred clinic. The most common reason for resignation or transfer to another specialty was heavy workload (n=46, 74.19%), followed by excessive hours of work (n=45, 72.58%). The most common reason for transfer to another orthopedics and traumatology clinic was drudgery (n=10, 45.5%), followed by problems with the hierarchy in orthopedics and traumatology residency (n = 9, 40.9%). CONCLUSION The results of this survey have shown us, with an overall resignation rate of 8.2% as per the total quotas for OT residency from 2013 to 2020, that resignation from OT residency represents an important problem in Turkey. Workload and excessive hours of work were the most common reasons for resignation from orthopaedic residency programmes. Furthermore, extra work that diverted residents from their actual job responsibilities, as well as academic and educational concerns, were the main factors leading to transfer to another OT residency programme.

Abstract
Background Because of the broad anatomic variation in the course of the axillary nerve, several cadaveric studies have investigated the acromion-axillary nerve distance and its association with the humeral length to predict the axillary nerve location. This study aimed to analyze the acromion-axillary nerve distance (AAND) and its relation to the arm length (AL) in patients who underwent internal plate fixation for proximal humerus fractures. Methods The present prospective study involved 37 patients (15 female, 22 male; the mean age = 51 years, age range 19–76) with displaced proximal humerus fractures treated by open reduction and internal fixation. After anatomic reduction and fixation were achieved, the following parameters were measured in each patient before wound closure without making an extra incision or dissection: (1) the distance from the anterolateral edge of the acromion to the course of the axillary nerve was recorded as the acromion-axillary nerve distance and (2) the distance from the anterolateral edge of the acromion to the lateral epicondyle of the humerus was recorded as arm length. The ratio of AAND to AL was then calculated and recorded as the axillary nerve index (ANI). Results The mean AAND was 6 ± 0.36 cm (range 5.5–6.6), and the mean arm length was 32.91 ± 2.9 cm (range 24–38). The mean axillary nerve ratio was 0.18 ± 0.02 (range 0.16 to 0.23). There was a significant moderate positive correlation between AL and AAND (p = 0.006; r = 0.447). The axillary nerve location was predictable in only 18% of the patients. Conclusion During the anterolateral deltoid-splitting approach to the shoulder joint, 5.5 cm from the anterolateral edge of the acromion could be considered a safe zone to prevent possible axillary nerve injury.

Temporary Epiphysiodesis Using the Eight-Plate in the Management of Children with Leg Length Discrepancy: A Retrospective Case Series. Indian J Orthop 2022; 56:874-882. [PMID: 35547335 PMCID: PMC9043087 DOI: 10.1007/s43465-021-00599-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Accepted: 12/28/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND Although eight-plates have been shown to be effective in correcting angular deformities of the knee, the literature is scarce regarding the efficiency of this method in treatment of children with LLD. OBJECTIVES The aim of this study was to determine the efficiency, rates of correction and complications of epiphysiodesis using eight-plate in the management of children with leg length discrepancy (LLD). METHODS Eleven consecutive patients with LLD (7 boys, median age = 9, age range 6-11 years) who were treated by temporary epiphysiodesis using eight-plates were retrospectively reviewed and included in the study. The main indication for temporary epiphysiodesis was an LLD between 2 and 5 cm in all patients. LLD and lower limb alignment were examined on lower extremity weight-bearing radiography preoperatively and at skeletal maturity. Longitudinal correction rate was calculated. The final LLD was categorized as ''good result'' (final LLD < 1.5 cm), ''fair result'' (1.5-2 cm), and ''poor result'' (> 2 cm). RESULTS The mean treatment period with the eight-plate was 44 (min to max = 32-72) months, and the mean follow-up from the index surgery to the final follow-up was 62 (min to max = 39-106) months. The mean LLD was significantly reduced from 39 (range 25-50) mm preoperatively to 22.40 (range 6-55) mm postoperatively (p = 0.006). The mean longitudinal correction rate was found to be 0.48 mm/mo. Radiographic evidence of lower limb deformity in frontal and sagittal planes was determined in neither preoperative nor postoperative deformity analysis. No major complications were recorded. CONCLUSION For the management of children with LLD of 2-5 cm, temporary hemiepiphysiodesis using the eight-plate seems to be an effective treatment with low complication rates.

Abstract
PURPOSE OF THE STUDY The literature is conflicting as to whether the high hip center (HHC) reconstruction in total hip arthroplasty (THA) is an ideal option for patients with severe developmental dysplasia of the hip (DDH). This study aimed to compare the mid-term functional and radiographic outcomes of THA using HHC versus anatomical hip center (AHC) technique in Crowe types II and III DDH. Our hypothesis was that there may be no differences in terms of functional and radiographic outcomes between patients who underwent THA using HHC or AHC. MATERIAL AND METHODS Fifty-seven patients who underwent a primary THA due to Crowe type-II or type-III DDH were retrospectively reviewed and included. Patients were divided into two groups as per the hip center reconstruction: Group A (AHC technique) and group H (HHC technique). A cementless cup was inserted in 25 hips (19 female, 6 male; mean age = 51 years, age range = 28-67)) at near-AHC in group A and 32 hips (22 female, 10 male; mean age = 53 years, age range = 29-68) at HHC position in group H. To assess clinical status, the Harris Hip Score (HHS) was used at the final follow-up. In radiographical assessment, component loosening and osseointegration of the acetabular cup were examined on follow-up radiographs. Complications were also recorded. RESULTS The mean follow-up was 41 months (range, 25-84) in group A and 40 months (range, 24-86) in group H. The mean HHS was 83 (range, 74-91) in group A and 83.6 (range, 73-94) in group H (p = 0.741). Osteolysis was determined in three patients from each group. The other 51 cups demonstrated a minimum of one radiographic sign of osseointegration. Although the overall complication rate was higher in group A (64%) than in group H (46%), this difference reached no statistical significance (p = 0.11). CONCLUSIONS The HHC technique using cementless acetabular fixation seems to be a valuable alternative option to AHC technique in cases of Crowe types II and III DDH. Key words: High hip center; anatomical hip center; center of rotation; total hip arthroplasty; dysplastic hip; developmental dysplasia of the hip; Crowe type II; Crowe Type III.

Abstract
BACKGROUND The literature is scanty regarding the biomechanical effects of different thread configurations on the initial stability of ankle arthrodesis. This study aims to compare the initial stability of tibiotalar fusion site in ankle arthrodesis using cannulated screws with different thread designs. METHODS We biomechanically tested under cyclic loading the effects of different screw combinations on the initial stability of ankle arthrodesis. A total of 28 synthetic ankle models were divided into four groups: two partially threaded cancellous screws (group A), partially and fully threaded cancellous screws (group B), a partially threaded cancellous screw with a headless compression screw (group C), and a fully threaded cancellous screw and a headless compression screw (group D). Biomechanical variables including ultimate failure load, initial stiffness, ultimate stiffness, and failure angulation were analyzed. RESULTS There were no differences in any of the biomechanical variables among the four groups (P = .41 for ultimate failure load, P = .079 for initial stiffness, P = .084 for ultimate stiffness, and P = .937 for failure angulation). CONCLUSIONS Combinations of different cannulated screws showed similar results in terms of the stability and stiffness of the tibiotalar fusion site.

Abstract
The present study aims to investigate whether there is a relationship between the ligamentous injury pattern and concomitant neurovascular injury with long-term functional outcomes in patients with traumatic knee dislocations (TKDs). A total of 42 patients with TKDs were categorized according to the Schenck's classification based on the pattern of ligamentous injury. Concomitant vascular and neural injuries were recorded. Long-term functional outcomes were assessed using several objective and subjective outcome measures. This retrospective study was conducted in two phases: (1) to analyze the impact of ligamentous injury pattern on functional outcomes of patients with TKDs in the overall study population, by comparing all the variables among Schenck's grades; (2) to determine the impact of concomitant vascular and neural injury on ultimate knee function based on the subgroup analyses. In the overall study statistical differences were determined among each pattern of ligamentous injury in the total range of motion (ROM) and scoring systems (chi-squared test, p = 0.254). The overall rates of vascular and neural injury were 26 and 28%, respectively. In subgroup analyses, 40 patients were divided into three subgroups: group A (isolated concomitant neural injury), group B (isolated concomitant vascular injury), group C (without concomitant major vascular or neural injury). The analysis revealed a significant difference in the total ROM (p = 0.005), flexion measurements (p = 0.004), and the loss of extension (p = 0.003). Group A had the lowest total knee ROM and the mean flexion degrees, as well as the highest loss of extension. Concerning functional scoring systems including the combined Knee Society Score (knee score + function score), Lysholm knee scoring scale, and International Knee Documentation Committee score, subgroup analyses revealed significant differences among the groups (p = 0.001, p < 0.01 for all scores). All the scores were found to be lowest in group A. Evidence from the current study showed that the ligamentous pattern and concomitant neurovascular injury both may have a significant impact on ultimate knee function in patients with TKDs. This is a Level III-retrospective comparative study.

Abstract
This study aimed to compare clinical and radiographical results of total or partial resection of the cross-bone in the management of children with cleft hand. Nine children with 10 cleft hands who underwent resection of the cross-bone were retrospectively identified and divided into two groups based on type of resection: Group T (total resection) including 5 children (5 affected hands; 3 boys; mean age = 3.5 (range, 2-5) years), and Group P (partial resection) including 4 children (5 affected hands; 3 boys; mean age = 3.2 (range, 2-5) years). Mean follow-up was 68 (range, 60-85) months in group T and 47 (range, 40-60) months in group P. To assess clinical status, postoperative cosmetic satisfaction was evaluated by asking the parents, and cosmetic appearance was rated using a visual analogue scale (VAS) at the follow-up. In the radiographical evaluation, change in cleft divergence following reconstruction was assessed as the metacarpal divergence angle between the index and the ring finger metacarpals. Overall, cosmetic satisfaction was rated "very satisfied" or "satisfied" in 7 of the 10 hands, and functional satisfaction as "very satisfied" or "satisfied" in all. Mean postoperative cosmetic aspect on VAS was 6.4 (range, 5-8) in group T, and 6.2 (range, 4-8) in group P (p = 0.99). Mean metacarpal divergence angle significantly decreased from 42.2° (range, 35-52°) and 40.2° (range, 36-46°) preoperatively to 21.2° (range, 15-35°) and 19.8° (range = 12-31°) at 3-year follow-up in groups T and P, respectively (p < 0.001 for each group). Both total and partial cross-bone resection provided satisfactory clinical and radiographical medium-term results for of children with cleft hand.

Abstract
The present randomized controlled study aims to evaluate whether tourniquet application during total knee arthroplasty (TKA) has an effect on (1) thigh muscle strength (quadriceps and hamstring muscle strength) and (2) clinical outcomes (postoperative knee range of motion [ROM], postoperative pain level, and Knee Society Score [KSS]). The effects of tourniquet application during TKA were investigated in 65 patients randomly allocated to one of two groups: TKA with a tourniquet and TKA without a tourniquet. Patients in both groups were comparable in terms of the demographic and clinical data (p > 0.05 for age, number of patients, sex, radiographic gonarthrosis grade, American Society of Anesthesiologists [ASA] classification, and body mass index [BMI]). All patients in both groups were operated by the same surgeon using one type of prosthesis. Isokinetic muscle strength (peak torque and total work) of knee extensors (quadriceps) and flexors (hamstrings) was measured in Newton meters (Nm) using a CYBEX 350 isokinetic dynamometer (HUMAC/CYBEX 2009, Stoughton, MA). The combined KSS (knee score + function score), visual analog scale (VAS), and knee ROM were measured preoperatively and at 1 and 3 months postoperatively to evaluate clinical outcomes. There were no significant differences between the two groups in preoperative and postoperative values of isokinetic muscle strength (peak torque and total work) and aforementioned clinical outcomes (p < 0.05). The present study has shown that quadriceps strength and clinical outcomes were not improved in the early postoperative period (3 months) when a tourniquet was not used during TKA.

Abstract
BACKGROUND The present study aimed to investigate diagnostic values of C-reactive protein (CRP), white blood cell (WBC), erythrocyte sedimentation rate (ESR), neutrophil to lymphocyte ratio (NLR), and the platelet to lymphocyte ratio as possible indirect inflammatory markers in children with septic arthritis (SA) for diagnosis process. METHODS The medical records of pediatric patients with SA who underwent debridement surgery between February 2005 and November 2018 were obtained from the hospital records. A total of 59 children with SA and 60 age- and gender-matched healthy controls were enrolled in the study. Hemograms parameters including WBC count, neutrophil count, lymphocyte count, hemoglobin, platelet count, CRP, ESR, NLR, and platelet to lymphocyte ratio. Biochemical parameters including alanine transaminase, aspartate aminotransferase, blood urea nitrogen, creatinine, glucose, and albumin were investigated and compared between both groups. RESULTS Fifty-nine patients, 30% female (n: 18) and 70% male (n: 41), who had received operations for SA were included in the study. The mean age of the patients was 7.1 (range 6 days to 15 years) years and mean follow up 56.6 (12-140) months. No significant differences were observed in any biochemical parameters between the groups. However, a significant difference was found between the septic arthritis and the control group in all hemogram parameters. CONCLUSIONS Although the sensitivity and specificity of the NLR are lower than CRP, ESR, and WBC which are most commonly used inflammatory parameters in diagnosis process of septic arthritis, NLR may be useful in confirming the diagnosis in the clinical practise, with an optimum diagnostic cut-off value of 4.05.

Abstract
Background Salvage procedures, such as proximal row carpectomy, limited or total wrist arthrodesis, and wrist replacement, are generally preferred to treat advanced Kienböck's disease. However, these procedures are particularly aggressive and may have unpredictable results and potentially significant complications. Questions/Purpose This study aimed to present the short- to mid-term clinical and functional results of arthroscopic debridement and arthrolysis in the management of advanced Kienböck's disease. Patients and Methods Fifteen patients in whom Lichtman Stages IIIA to IIIC or IV Kienböck's disease was diagnosed and treated by arthroscopic wrist debridement and arthrolysis were included in this retrospective study. The mean age was 30 years (range: 21-45). The mean follow-up period duration was 36 months (range: 18-60). The Disabilities of the Arm, Shoulder, and Hand (DASH) score, visual analog scale (VAS), wrist range of motion (ROM), and grip strength were measured preoperatively and then again at the final follow-up visit. Results The mean DASH and VAS scores improved from 41 (range: 31-52) and 7.1 (range: 6-8) preoperatively to 13 (range: 8-21) and 2 (range: 0-3; p < 0.001) at the final follow-up visit, respectively. The mean wrist flexion and extension values increased from 32 (range: 20-60 degrees) and 56 degrees (range: 30-70 degrees; p = 0.009) preoperatively to 34 (range: 10-65 degrees; p = 0.218) and 57 degrees (range: 30-70 degrees; p = 0.296) at the final follow-up appointment, respectively, although these findings were statistically insignificant. The mean strength of the hand grip increased from 22.7 (range: 9-33) to 23.3 (range: 10-34; p = 0.372). Conclusion Arthroscopic debridement and arthrolysis may improve wrist function and quality of life due to the preserved ROM and hand grip strength after short- to mid-term follow-up periods despite the radiographic progression of Kienböck's disease. Level of Evidence This is a Level IV, retrospective case series study.

Abstract
CASE A 40-year-old man was admitted to our emergency department with a painful and swollen calf. There was no history of significant trauma, and the physical examination revealed a pulseless, swollen left lower leg. Clinical history revealed a diagnosis of primary myelofibrosis, and magnetic resonance imaging showed a rupture of the gastrocnemius medial head. The diagnosis of spontaneous acute extremity compartment syndrome (AECS) secondary to myelofibrosis was established. An open fasciotomy procedure was performed, and recombinant factor VIIa treatment was applied to control bleeding. Postoperatively, fasciotomy wounds were closed with skin grafts. CONCLUSION AECS may develop in patients with bleeding disorders, and recombinant factor VII may help control bleeding.

Abstract
OBJECTIVE Osteonecrosis (ON), also known as avascular necrosis, is characterized by the collapse of the architectural bone structure secondary to the death of the bone marrow and trabecular bone. Osteonecrosis may accompany many conditions, especially rheumatic diseases. Among rheumatic diseases, osteonecrosis is most commonly associated with systemic lupus erythematosus (SLE). We assessed prevalence and distribution pattern of symptomatic ON in patients with SLE and compare the natural courses of hip and knee ON. METHODS 912 SLE patients admitted between 1981 and 2012 were reviewed. SLE patients with symptomatic ON were retrospectively identified both from the existing SLE/APS database. The prevalence of symptomatic ON was calculated; with ON, the joint involvement pattern was determined by examining the distribution of the joints involved, and then the data about the hip and knee joints were entered in the Kaplan-Meier analysis. Kaplan-Meier methods were used to calculate 5- and 10-year rates of ON-related hip (the hip group) and knee survival (the knee group). RESULTS Symptomatic ON developed in various joints in 97 of 912 patients with SLE, and the overall prevalence of ON was detected as 10.6%. The mean age at the time of SLE and ON diagnoses were 27.9 ± 9.9 (14-53) and 34.2 ± 11.3 (16-62) years, respectively. The mean duration from diagnosis of SLE to the first development of ON was 70.7± 60.2 (range = 0-216) months. The most common site for symptomatic ON was the hips (68%, n=66), followed by the knees (38%, n = 37). According to Kaplan-Meier analysis, hip and knee joint survival rates associated with 5-year ON were 51% and 88%, and 10-year survival rates were 43% and 84%, respectively. CONCLUSION We observed that the prevalence of symptomatic ON in patients with SLE was 10.6%. With the estimated 10-year survival rates of 40% versus 84% for the hip and knee joints, respectively, hip involvement may demonstrate a more aggressive course to end-stage osteoarthritis than the knee involvement.

Abstract
OBJECTIVE The aim of this study was to present mid-term functional and radiological outcomes of patients with physeal closure who underwent arthroscopic or open internal fixation with headless cannulated compressive screws due to unstable Osteochondritis Dissecans (OCD) lesions of the knee. METHODS With a diagnosis of unstable OCD of the knee, ten consecutive patients (seven male, three female) with physeal closure (mean age: 23 years; range: 17-40), underwent arthroscopic or open internal fixation with headless cannulated compressive screws. The patients were retrospectively reviewed based on functional and radiological data, with a mean follow-up of 42 months (range: 27-61). The average size of the defects was 4.2 cm2 with a range from 1.7 to 8 cm2 . The study protocol consisted of the Range of Motion (ROM), Tegner-Lysholm Score, Modified Cincinnati Rating System Questionnaire, Short Form-12 (SF-12) in addition to the plain radiograph and Computed Tomography (CT). Any development of arthrosis was assessed at the final follow-up according to the Internation Knee Documention Committee score (IKDC). RESULTS At the final follow-up, control plain radiographs and CT showed complete union of the fragments in nine patients; however, CT imaging illustrated nonunion of the fragment in one patient. The main Tegner-Lysholm Score increased from 59 (range: 11-63) preoperatively to 97 (range: 88-100) at the final follow-up. Modified Cincinnati Rating System Questionnaire and IKDC score were 97 (range: 93-100) and 96 (range: 92-100), respectively, at the final follow-up. In addition, in terms of SF-12, the mean physical component score was 47.5 (range: 42-49), and the mean mental component score was 57.25 (range: 48-63). CONCLUSION In patients with physeal closure, internal fixation using cannulated compressive screws may be an influential procedure for the OCD lesions of the knee ranging in size from medium to large.

Abstract
Few studies have investigated the reliability of Reimers' hip migration percentage (RMP) in children with cerebral palsy (CP). Most studies on the topic reflected rating results of physician with a similar level of experience from the same expertise. This study aimed to determine the effect of clinician's experience and expertise on the intra-and inter-observer reliability of RMP.In this retrospective observational study, hip radiographs of children with CP were identified. 5 observers with different degrees of working experience from 3 different clinical fields, including orthopedics, radiology, and physical medicine and rehabilitation, performed all RMP measurements. All measurements were repeated 6 weeks later by the same observers. Inter- and intra-observer reliability for RMP measurements were assessed using Intraclass Correlation Coeficient (ICC), calculated from 2 sets of repeated measurements on a subset of 50 hips, with a 6 week apart for each observer.Fifty hip radiographs of 25 children with CP (10 females and 15 males; mean age: 6 years; age range: 2-8 years) were examined in the current study. No significant differences existed in intra-and inter-observer measurements. Excellent intra-observer reliability was observed between the 2 separate measurements for each observer, with a mean ICC of 0.976 (range: 0.956-0.989; P < .001). Among 5 observers, inter-observer reliability was excellent for the 2 separate RMP measurements, with the mean ICC minimally increasing between the 2 measurement periods (mean ICC: 0.928, range: 0.838-0.979 and mean ICC: 0.936, range: 0.861-0.983, respectively) (P < .001).Clinician's experience and expertise may not affect inter-and intra-observer reliability of RMP measurements.

Abstract
We present a case of Abiotrophia defectiva in a prosthetic knee infection following total knee replacement for the first time. A 69-year-old female was prediagnosed with prosthetic knee infection, and a two-stage revision arthroplasty was applied. A. defectiva was cultured by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) from the synovial fluid aspirates. Penicillin G and gentamicin had been administered. One year postoperatively, a scintigraphy showed no recurrence. A. defectiva may be missed in culture negative patients with knee or hip arthroplasty. They should be carefully evaluated if they have undergone recent dental procedures.

Abstract
OBJECTIVE The aim of this study was to determine the effect of intravenous (IV) tranexamic acid (TRX) use on visual clarity during arthroscopic rotator cuff repair. METHODS This prospective, randomized, double-blinded, placebo-controlled study was conducted in patients scheduled for an arthroscopic rotator cuff repair. In total, 60 patients were randomly distributed into two groups: control (28 patients: 11 male, 17 female; mean age=53 years, age range=19-65) and TRX (32 patients: 15 male, 17 female; mean age=50, age range=18-69). In the TRX group, the arthroscopy was performed through the bolus IV administration of 10 mg/kg TRX in 100 ml isotonic saline solution. In the control group, the arthroscopy was performed through the bolus IV administration of 100 ml isotonic saline solution. In both the groups, the IV administration was carried out after the induction of anesthesia. At the end of each procedure, the surgeon rated the visual clarity on a scale from 1 to 10. In addition, operation time (minutes), irrigation amount used in operation (lt), and the need of pressure increase because of bleeding were recorded. RESULTS No adverse effects were seen during the study period. Visual clarity in TRX group was significantly better than the control group (the mean visual clarity scores=8.1/10 (range=7-10) vs 7/10 (range=5-9); p=0.018). The amount of solution was significantly less in the TRX group (10.2 lt (range=3.5-21)) than in the control group (15.8 lt (range=5.8-27); p=0.007, post-hoc power=95.7%), although the operation time was slightly longer in the TRX group (106 minutes (range=50-210)) than in the control group (99 minutes (range=45-165); p=0.24). Moreover, the need for the increase in pressure owing to bleeding was found significantly less in the TRX group (5.8 times (range=(0-9)) than in the control group (9.6 times (range=0-13); p=0.04, post-hoc power=94.5%). CONCLUSION Preoperative IV TRX administration seems to be effective in improving visual clarity and reducing the need for high pressure and the amount of irrigation fluid during the arthroscopic rotator cuff repair.

Abstract
Background and purpose - Hindfoot arthrodesis using retrograde intramedullary nailing assumes a critical role in limb salvage for patients with diabetic Charcot neuro-arthropathy (CN). However, this procedure is compelling and fraught with complications in diabetic patients. We report the mid-term clinical and radiological outcomes of retrograde intramedullary nailing for severe foot and ankle deformity in patients with diabetic CN.Patients and methods - Hindfoot arthrodesis was performed using a retrograde intramedullary nail in 24 patients (15 females) with diabetic Charcot foot. The mean age of the patients was 62 years (33-82); the mean follow-up was 45 months (24-70). The primary outcomes were rates of fusion, limb salvage, and complications.Results - The overall fusion rate was 23/24, and none of the patients needed amputation. The rate of superficial wound infection was 4/24, and no deep infection or osteomyelitis was observed postoperatively.Interpretation - For selected cases of diabetic CN with severe foot and ankle deformity, hindfoot arthrodesis using a retrograde intramedullary nail seems to be a good technique in achieving fusion, limb salvage, and avoidance of complications.

Abstract
BACKGROUND The effect of limb lengthening on neural structures was assessed with use of intraoperative neuromonitoring (IONM) during primary total hip arthroplasty (THA). The relationship between the critical limit of lengthening and anthropometric measurements was evaluated. METHODS Motor evoked potentials (MEPs) from the deep peroneal nerve (tibialis anterior muscle), tibial nerve (gastrocnemius muscle), and femoral nerve (quadriceps muscle), as well as somatosensory evoked potentials (SEPs) from the posterior tibial nerve, were recorded in 16 patients undergoing THA. Height, weight, the distance between the anterior superior iliac spine and the medial malleolus (ASIS-MM distance), and the total femoral length were measured preoperatively. Lower-extremity traction was performed after resection of the femoral head, and the amount of extremity lengthening was measured with use of an image intensifier. A maximum of 50% reduction in any one of the SEP or MEP amplitudes or a 10% increase in the SEP latency were considered to be indicative of the critical limit of lengthening. RESULTS Initial IONM changes (indicating the safe limit of lengthening) and maximum allowed IONM changes (indicating the critical limit of lengthening) were reached in the deep peroneal nerve in all cases. The mean safe limit of lengthening (and standard deviation) was 14.9 ± 6.2 mm (3% relative to femoral length and 1.7% relative to ASIS-MM distance), whereas the critical limit of lengthening was exceeded at a mean of 22.4 ± 5.6 mm (5% relative to femoral length and 2.6% relative to ASIS-MM distance). When the critical limit was reached in the deep peroneal nerve, the mean decrease in MEP amplitudes was 27% (95% confidence interval [CI], 22.1% to 32.7%) for the tibial nerve and 12% (95% CI, 6.9% to 18.1%) for the femoral nerve. There was a positive correlation between critical lengthening and femoral length (r = 0.782; p < 0.001), ASIS-MM distance (r = 0.811; p < 0.001), and height (r = 0.835; p = 0.001). No correlation existed between the critical lengthening amount and the decrease in amplitude in the tibial and femoral nerves. CONCLUSIONS The critical limit of nerve lengthening was directly correlated with anthropometric measurements. Nerve lengthening of 5% relative to femoral length and of 2.6% relative to ASIS-MM distance was found to be critical; however, these limits depended on the predetermined threshold values for IONM.

Abstract
BACKGROUND Little data exist regarding the adverse effects of Achilles tendon (AT) elongation after rupture repair on plantarflexion strength. This study aimed to investigate the effect of AT elongation measured using AT resting angle (ATRA) on the plantarflexion strength in patients with surgically treated acute AT rupture. METHODS A retrospective chart review was performed on 40 patients (15 female and 25 female) who underwent open operative repair due to an acute AT rupture. At the final follow-up, AT elongation was assessed using ATRA. Plantarflexion strength (peak torques and angle-specific torques) was measured using an isokinetic dynamometer. All variables were obtained from the operated and unoperated contralateral ankles of the patients. RESULTS The mean ATRA was greater in the operated ankles (mean, 57 degrees; range, 39-71 degrees) compared with the unoperated ones (mean, 52 degrees; range, 36-66 degrees; P = .009). Except the plantarflexion torque at 20 degrees of plantarflexion (P = .246), all the other angle-specific torques were lower in the operated ankles (P < .05). Peak flexion torque at 30 degrees/s was lower in the operated ankle (P = .002). A negative correlation was found between operated/unoperated (O/N) ATRA and O/N plantarflexion torque ratios at 0 degrees (r = -0.404; P = .01), 10 degrees (r = -0.399; P= .011), and 20 degrees (r = -0.387; P = .014). CONCLUSION Postoperative AT elongation measured using ATRA may have a deleterious effect on the plantarflexion strength in patients with surgically treated acute AT rupture. LEVEL OF EVIDENCE Level IV, case series.
