Abstract
PURPOSE Glenoid tumors are extremely rare, and reconstruction remains very challenging. The aim of this study is to present the clinical and functional outcomes, of a new glenoid reconstruction method using 3-dimensional-printed implant. METHODS Four patients with primary glenoid tumors underwent reconstruction using 3-dimensional-printed glenoid implant linked with reverse shoulder arthroplasty. We retrospectively reviewed the clinical and functional outcome, using MSTS and DASH score, as well as complications' rate. RESULTS Wide excision was achieved in all patients. No local recurrence or distant metastasis was diagnosed at the follow-up period. The mean MSTS score was 80.5%, and DASH score was 15.2%. According to Hendersons' classification, there were no postoperative complications. CONCLUSION The use of 3-dimensional-printed implants, can be a very reliable solution with satisfying clinical and functional outcomes for reconstruction, in patients with musculoskeletal malignancies of the glenoid. Level of evidence IV Treatment Study.

Abstract
Background: Despite the expanding use of orthopedic devices and the application of strict pre- and postoperative protocols, the elimination of postoperative implant-related infections remains a challenge. Objectives: To identify and assess the in vitro and in vivo properties of antimicrobial-, silver- and iodine-based implants, as well as to present novel approaches to surface modifications of orthopedic implants. Methods: A systematic computer-based review on the development of these implants, on PubMed and Web of Science databases, was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: Overall, 31 in vitro and 40 in vivo entries were evaluated. Regarding the in vitro studies, antimicrobial-based coatings were assessed in 12 entries, silver-based coatings in 10, iodine-based in 1, and novel-applied coating technologies in 8 entries. Regarding the in vivo studies, antimicrobial coatings were evaluated in 23 entries, silver-coated implants in 12, and iodine-coated in 1 entry, respectively. The application of novel coatings was studied in the rest of the cases (4). Antimicrobial efficacy was examined using different bacterial strains, and osseointegration ability and biocompatibility were examined in eukaryotic cells and different animal models, including rats, rabbits, and sheep. Conclusions: Assessment of both in vivo and in vitro studies revealed a wide antimicrobial spectrum of the coated implants, related to reduced bacterial growth, inhibition of biofilm formation, and unaffected or enhanced osseointegration, emphasizing the importance of the application of surface modification techniques as an alternative for the treatment of orthopedic implant infections in the clinical settings.

Abstract
BACKGROUND Neurofibromatosis type 1 (NF1) is a genetic autosomal neurocutaneous syndrome correlated with skeletal dysplasia and defects in the osseous microarchitecture. The physiological mechanism for the development of NF1-related bone abnormal turnover is still unclear. OBJECTIVES A meta-analysis was performed to investigate the effects of NF1 on bone mineral density (BMD) and osseous metabolic indices in order to provide clinical evidence for the pathogenesis of the associated skeletal deformities. METHODS A systematic literature review search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in the PubMed/Medline and Web of Science databases from the date of inception of each database through to 10 September 2023. Specific inclusion and exclusion criteria were applied for the identification of studies examining the effects of NF1 on bone strength and metabolism. The Newcastle-Ottawa and Jadad scales were applied to assess the quality of the included studies. RevMan 5.3 software was used for the analysis of the data, and MedCalc was applied to examine publication bias. RESULTS Overall, 13 studies met the inclusion criteria comprised of 5 cross-sectional, 6 case-control and 2 retrospective studies. 703 patients and 973 healthy subjects formed the NF1 and control group, respectively. The results of the meta-analysis displayed that lumbar (SMD = -3.85, 95%CI = -7.53 to -0.18, Z = 2.05, p = 0.04) and femoral (SMD = -4.78, 95%CI = -8.86 to -0.69, Z = 2.29, p = 0.02) BMD was reduced in the NF1 group. Both in children and adults the serum levels of 25 hydroxyvitamin D3 were also decreased in NF1 group, but without any statistical significance (SMD = -0.62, 95%CI = -1.34 to -0.11, Z = 1.66, p = 0.10). Serum Parathyroid hormone (PTH) (SMD = 0.73, 95%CI = 0.31 to 1.15, Z = 3.43, p = 0.0006) and C-telopeptide of type 1 collagen (CTX) (SMD = 0.82, 95%CI = 0.33 to 1.30, Z = 3.29, p = 0.001) were elevated in NF1 patients, while serum calcium (SMD = -0.10, 95%CI = -0.74 to 0.53, Z = 0.32, p = 0.75) phosphorous (SMD = 0.33, 95%CI = -0.38 to 1.05, Z = 0.92, p = 0.36), alkaline phosphatase (ALP) (SMD = -0.36, 95%CI = -0.77 to 0.05, Z = 1.71, p = 0.09), osteocalcin (SMD = 1.81, 95%CI = -0.37 to -3.98, Z = 1.63, p = 0.10) and bone formation markers (SMD = 0.28, 95%CI = -0.37 to -0.94, Z = 0.85, p = 0.39) were not. CONCLUSION NF1 is associated with decreased BMD at the lumbar spine and femur. Taking into account that the serum levels of PTH, CTX were increased whereas the concentrations of vitamin D, calcium, phosphorous, ALP, osteocalcin and bone formation markers were not altered significantly in the NF1 patients compared with the healthy subjects, a vitamin D independent dysregulated bone cellular activity could be considered.

Abstract
Case A 30-year-old male was admitted in our hospital having an open left distal femoral fracture with 9-cm segmental bone defect and a closed proximal left tibial fracture. He was treated successfully using a Hybrid (Titanium Cage and Bone Graft) Masquelet Induction Membrane Technique (MIMT). His femoral fracture united 3-months post - operatively. The left tibia was treated initially with two locking plates. Following infection, a 3-cm tibial bone gap was treated with external fixation and conventional MIMT. The tibial fracture united 12-months post- operatively. Conclusion The Hybrid MIMT achieved a successful healing outcome in this challenging case.

Abstract
BACKGROUND The triad of 3D design, 3D printing, and xReality technologies is explored and exploited to collaboratively realize patient-specific products in a timely manner with an emphasis on designs with meta-(bio)materials. METHODS A case study on pelvic reconstruction after oncological resection (osteosarcoma) was selected and conducted to evaluate the applicability and performance of an inter-epistemic workflow and the feasibility and potential of 3D technologies for modeling, optimizing, and materializing individualized orthopedic devices at the point of care (PoC). RESULTS Image-based diagnosis and treatment at the PoC can be readily deployed to develop orthopedic devices for pre-operative planning, training, intra-operative navigation, and bone substitution. CONCLUSIONS Inter-epistemic symbiosis between orthopedic surgeons and (bio)mechanical engineers at the PoC, fostered by appropriate quality management systems and end-to-end workflows under suitable scientifically amalgamated synergies, could maximize the potential benefits. However, increased awareness is recommended to explore and exploit the full potential of 3D technologies at the PoC to deliver medical devices with greater customization, innovation in design, cost-effectiveness, and high quality.

Abstract
INTRODUCTION Knee arthrodesis is a limb salvage intervention for persistent periprosthetic joint infection (PJI) when revision total knee arthroplasty fails. Conventional arthrodesis techniques are associated with the increased rate of complications, especially in patients with extensive bone loss and extensor tendon deficiency. METHODS Eight patients with a modular silver-coated arthrodesis implant after failed exchange arthroplasty for infection, were retrospectively reviewed. All patients had significant bone loss, while 5 displayed extensor tendon deficiency. Survivorship, complications, leg length discrepancy, median Visual Analogue Scale (VAS) and Oxford Knee score (OKS) were evaluated. RESULTS The median follow up was 32 months (range 24-59 months). The survivorship rate of the prosthesis was 86% during the minimum time of follow up of 24 months. In one patient recurrence of the infection was observed and above-knee amputation was performed. The median postoperative leg length discrepancy was 2.07 ± 0.67 cm. Patients were able to ambulate with mild or no pain. The median VAS and OKS was 2.14 ± 0.9 and 34.7 ± 9.3, respectively. CONCLUSIONS The results of our study demonstrated that knee arthrodesis with a silver coated arthrodesis implant, performed for persistent PJI in patients with significant bone loss and extensor tendon deficit, provided a stable construct, allowed eradication of infection and was associated with good functional outcome.

Abstract
PURPOSE Running, jumping/landing and cutting/change of direction (CoD) are critical components of return to sport (RTS) following anterior cruciate ligament reconstruction (ACLR), however the electromyographic (EMG) activity patterns of the operated leg during the execution of these tasks are not clear. METHODS A systematic review was conducted to retrieve EMG studies during running, jumping/landing and cutting/(CoD) in ACLR patients. MEDLINE, PubMed, SPORTDiscus and Web of Science databases were searched from 2000 to May, 2022 using a combination of keywords and their variations: "anterior cruciate ligament reconstruction" OR "ACLR", "electromyography" OR "EMG", "running", "jumping" OR "landing", "cutting" OR "change-of-direction" OR "CoD". The search identified studies comparing EMG data during running, landing and cutting/(CoD) between the involved limb and contralateral or control limbs. Risk of bias was assessed and quantitative analyses using effect sizes were performed. RESULTS Thirty two studies met the inclusion criteria. Seventy five percent (24/32) of the studies reported altered EMG activity pattern of the ACLR leg during running, jumping/landing and cutting/(CoD) when compared with either the healthy control leg or the contra-lateral leg. Twelve studies showed decreased, delayed or earlier onset and delayed peak in quadriceps EMG activity with small to large effect sizes and 9 studies showed increased, delayed or earlier onset and delayed peak in hamstrings EMG activity with small to large effect sizes. Four studies showed a "hamstrings-dominant" strategy i.e. decreased quadriceps coupled with increased hamstrings EMG activity in both running and jumping/landing irrespective of graft type. One study reported that on the grounds of decreased quadriceps activity, lower hamstrings EMG activity was predictive of ipsilateral re-injury in ACLR patients. CONCLUSION This systematic review of Level III evidence showed that the ACLR leg displays decreased quadriceps or increased hamstrings EMG activity or both despite RTS. Simultaneous decreased quadriceps and increased hamstrings EMG activity was shown for both running and jumping/landing. From a clinical perspective this "hamstrings dominant" strategy can serve as a protective mechanism against graft re-injury. LEVEL OF EVIDENCE III.

Abstract
Osteoarthritis is a degenerative joint disease affecting middle-aged and elderly patients. It mainly involves weight-bearing joints such as the hip, knee and spine as well as the basilar joint of the thumb, causing dysfunction and painful symptoms. Often, joint arthritis is accompanied by cartilage defects, joint space narrowing, osteophytes, bone sclerosis and subchondral bone cysts (SBC). The aim of the present study was to explore the pathophysiology responsible for the development of SBCs as well as the association between SBCs and disease progress, the level of clinical symptoms and their impact on postoperative outcomes and risk of possible complications following joint replacements if left untreated. A literature review on PubMed articles was conducted to retrieve and evaluate all available evidence related to the main objective mentioned above. A few theories have been put forth to explain the formation process of SBCs. These involve MMPs secretion, angiogenesis, and enhanced bone turnover as a biological response to abnormal mechanical loads causing repeated injuries on cartilage and subchondral tissue during the development of arthritis. However, the application of novel therapeutics, celecoxib-coated microspheres, local administration of IGF-1 and activated chondrocytes following surgical debridement of SBCs hinders the expansion of SBCs and prevents the progression of osteoarthritis.

Abstract
PURPOSE The aim of this study was to highlight the impact of the COVID-19 pandemic on the practice of orthopaedics in Greece and Cyprus. METHODS The survey used the online questionnaire from AGA (Gesellschaft für Arthroskopie und Gelenkchirurgie; Society for Arthroscopy and Joint Surgery) to facilitate the comparison between different European countries. The questionnaire was distributed online to members of the HAOST (Hellenic Association of Orthopaedic Surgery and Trauma), the ΟΤΑΜΑΤ (Orthopaedic and Trauma Association of Macedonia and Thrace) and the CAOST (Cypriot Association of Orthopaedic Surgery and Trauma). The questionnaire consisted of 29 questions, which included demographic data, questions on the impact of the pandemic on the practice of orthopaedic surgery and questions on the impact on the personal and family life of orthopaedic surgeons. RESULTS The questionnaire was sent to 1350 orthopaedic surgeons in Greece and Cyprus, 303 of whom responded (response rate 22.44%). 11.2% of the participants reported cancellation of overall orthopaedic procedures. According to 35.6-49.8% of the participants, arthroscopic procedures were continued. As regards elective primary arthroplasties, 35.3% of the participants reported that these continued to be performed at their hospitals. Post-operative follow-ups as well as physiotherapy were affected by the pandemic, and changes were also observed in the habits of orthopaedic surgeons in their personal and family lives. CONCLUSION The orthopaedic service in Greece and Cyprus decreased during the first wave of the COVID-19 pandemic. Arthroscopic procedures and total joint replacements decreased significantly, but not to the same extent as in other countries. Health systems were not fully prepared for the first wave of the pandemic and the various countries took social measures at different times and to different extents. Thus, studying the impact of the pandemic on the practice of orthopaedic surgery in different countries can help health systems to better prepare for future pandemics; public health can then be shielded and hospitals can continue to provide high-quality orthopaedic care.

Abstract
Below-knee amputation is the treatment of choice for distal tibia malignancies, considering the specific anatomic features of the distal leg and ankle. However, advances in imaging modalities and adjuvant therapies and improved surgical techniques have made limb salvage surgery increasingly possible. The distal tibia is an uncommon location for malignant bone tumors, and there is limited information about limb salvage and reconstruction. Currently, 3-dimensional printed implants may successfully address reconstruction challenges after tumor resection. We present a patient with high-grade osteosarcoma of the distal tibia who underwent limb salvage and distal tibia and ankle joint replacement with a 3-dimensional printed endoprosthesis.

Abstract
Prosthetic reconstruction after wide resection of tumors of the proximal humerus presents a unique challenge. The shoulder is a complex articulation, and patients have high expectations for postoperative function. The goal of this study is to compare functional outcomes, oncologic outcomes, and complication rates for 2 reconstructive methods. Forty patients with proximal humeral tumors were reviewed retrospectively. Proximal humeral endoprosthesis (PHE) was used for 21 patients, and reverse shoulder arthroplasty (RSA) was used for 19 patients. Clinical results, oncologic outcomes, and complication rates were assessed. The functional outcomes of the patients were assessed with the Musculoskeletal Tumor Society scoring system (MSTS), the shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, and shoulder range of motion. The mean follow-up was 62±15 months. Shoulder dislocations occurred among 8 patients with PHE and 1 patient with RSA (P=.021). The other complication rates were similar for the 2 groups (P<.05). At the latest follow-up, the mean MSTS score was 68±10.3 for those with PHE and 76±7.7 for the patients with RSA (P=.72). However, the QuickDASH score was significantly better (P=.031) for those with RSA (mean, 19±6.3) compared with patients with PHE (mean, 30±4.8). Additionally, shoulder active abduction and forward flexion were significantly greater for the RSA group (P=.04 and P=.03, respectively). Five patients had local recurrence. Prosthetic reconstruction after oncologic re-section of the proximal humerus is associated with significant limitation of shoulder range of motion and a high rate of revision surgery. However, in this study, RSA was associated with fewer dislocations, improved Quick-DASH score, and greater abduction and forward flexion compared with PHE. [Orthopedics. 2022;45(6):e335-e341.].

Abstract
Introduction Periprosthetic joint infection (PJI) is a devastating complication occurring in 1–2% of primary and up to 10% of revised total hip and knee arthroplasties (THA and TKA) impairing patient's quality of life. Occult infections are underdiagnosed, sub-treated and sub-clinically experienced by patients. This study aimed to correlate patients' clinical outcomes with early antibiotic treatment based on use or non-use of a sonication technique on explanted prostheses. Methods 33 patients with revised THA or TKA were retrospectively evaluated. Clinical outcomes were assessed via Oxford hip or knee scores, and correlated with administration or not of antibiotic treatment based on sonication results. Results According to laboratory findings the patients were divided in the following three groups: 1. Septic loosening (conventional cultures and/or sonication positive), 2. Aseptic loosening (conventional cultures and sonication negative) and 3. Occult loosening (conventional cultures negative, sonication not performed). The average Oxford score was poor (27.9/60) for the septic, excellent (43.8/60) for the aseptic and intermediate (37.7/60) for the occult group. Additionally, conventional cultures were negative, but sonication-positive, in 6 individuals with patient-related risk factors (male gender, BMI > 30 kg/m2, diabetes, hypertension, steroids and rheumatoid arthritis). Conclusions Sonication represents a valuable diagnostic technique to guide administration of effective antibiotic treatment for patients, especially for detection of persistent post-revision occult infections. We recommend the systematic investigation of revised prostheses with a sonication technique, but especially in cases with risk factors for infection who it is suspected may have occult loosening.

Abstract
INTRODUCTION Osteosarcoma (OS) is the most common primary osseous malignant tumour, with high propensity to metastasise in lungs. Pulmonary micro-metastases are present in up to 80% of patients at initial diagnosis and they are associated with significantly worse prognosis. Doxycycline (Dox) is a synthetic tetracycline that has been shown to have anti-cancer properties in vitro and in vivo, and inhibit angiogenesis - effects that may prove beneficial for several types of cancer. The aim of the present work was to study how Dox affects OS cell growth in vitro and in vivo and OS-driven pulmonary metastasis in vivo. METHODS In vitro, the effect of Dox was measured in MG-63 and 143B human OS cell viability, apoptosis, invasion and migration. In vivo, highly metastatic 143B cells were orthotopically implanted into the tibia of SCID mice. The tumour growth and pulmonary metastases between Dox treated and untreated, non-amputated and early amputated xenografts were examined. RESULTS In vitro, Dox decreased viability, inhibited invasion, migration, and induced the apoptosis of OS cells. In vivo, Dox significantly enhanced tumour necrosis at primary OS sites, similarly to its in vitro effect, and downregulated the expression of Ki67, MMP2, MMP9, VEGFA and ezrin. It also decreased circulating VEGFA and MMP9 protein levels, in line with the decreased metastatic burden in Dox-treated mice (non-amputated and early-amputated). CONCLUSIONS Reprofiling of Dox can prevent the evolvement of pulmonary micro-metastases to clinically detectable macro-metastases and suppress the lethal progress of OS by inhibiting the expression of MMPs, VEGFA and ezrin at primary sites.

Abstract
Background Osteoarthritis (ΟΑ) is characterized by cartilage breakdown and subchondral sclerosis. Micro‐fractures of the calcified tissues have been, also, detected, but their exact role has not been elucidated yet. This study was to examine the frequency of cracks during OA progression and to correlate them with the underlying cellular modifications and matrix metalloproteinase‐2 (MMP‐2) expression using histological/immunohistological methods. Methods Overall, 20 patients and 3 controls (9 specimens per patient), aged 60–89 years, diagnosed with hip/knee OA were included. The development of cracks was examined in 138 sections, whereas the expression of MMP‐2 was examined in 69 additional sections. Results Based on Mankin score, three groups of OA severity were analyzed: Group I (mild) was constituted of sections with score 1–5 while Groups II (moderate) and III (severe) with score 6–7 and greater or equal to 8, respectively. Demographic characteristics did not reveal any association between the number of microdefects and age or body mass index (BMI). Cartilage micro‐cracks were increased during moderate and severe OA, while bone cracks were increased during mild and severe OA. In knee OA, cartilage cracks were not correlated with Mankin score, whereas in hip OA they appeared association with severity score. Bone cracks were positively correlated with matrix apoptotic osteocytes and osteoblastic cells, but not with osteoclasts. MMP‐2 immunostaining was increasing by OA severity in the osteochondral unit. Similarly, MMP‐2 was expressed on the microcracks’ wall mainly in Group III. Conclusion Our data displayed that bone cracks during primary OA stages, represent an early adaptative mechanism aiming to maintain cartilage integrity. Accumulation of bone defects and concomitant increase of apoptotic osteocytes activated an abnormal remodeling due to osteoblastic activity, in which MMP‐2 played a pivotal role, leading to subchondral sclerosis promoting further osteochondral deformities.

Abstract
Introduction: Neurofibromatosis Type 1 (Nf1), also termed von Recklinghausen disease, is a rare autosomal dominant genetic disorder accompanied by several osseous and skeletal manifestations. In NF, hypophosphatemia linked to secondary hyperparathyroidism due to Vitamin D deficiency and low calcium intake has been reported as a risk factor for low bone mass density (BMD), but reports of NF1 associated oncogenic hypophosphatemic osteomalacia (HO) are extremely rare. Case Report: We report a patient with NF1 associated with intracranial low-grade gliomas and congenital renal agenesis suffering from HO. Bone defects and deformities such as generalized bone pains located in feet, ankles and lower limbs, thoracic scoliosis, mild bowing of long bones of lower limbs, stress fractures, and old fractures as well as with altered bone metabolic serum markers were present. After 8 weeks of follow-up, it was observed that the combination of oral administration of phosphate and Vitamin D improved her medical symptoms without significant changes in phosphate levels or BMD. Conclusion: Although renal agenesis is not correlated with hypophosphatemia, the coexistence of NF1, renal congenital deformities, and low-grade gliomas may contribute to disease severity. Conventional treatment with high doses of oral calcitriol associated with phosphate is efficient to improve the clinical and laboratory symptoms of the disease.

Abstract
Dr Marika Daniilidou was born in 1902 in Asia Minor. Her family was forced to immigrate to Greece, in 1922. Despite the horrendous difficulties of the era, she pursued undergraduate and postgraduate studies in the University of Berlin, Germany, and she specialized in orthopaedic surgery. In 1937, she became the first female certified orthopaedic surgeon in Greece. In 1947, she was the only female orthopaedic surgeon among the 22 founders of the Hellenic Association of Orthopaedic Surgery and Traumatology (HAOST). She became a true role model for the next generations of Greek women surgeons.

Abstract
There is ongoing controversy regarding the best treatment of fingertip amputations, conservative treatment with secondary healing or surgical intervention. Healing by secondary intention has been proven to offer satisfactory recovery and function. More extensive wounds are treated surgically. However, even in Allen III and IV amputations, there is a lack of evidence to support enhanced healing and function of fingertips after surgical treatment compared to conservative management. Regarding fingertip amputations after animal bites, thorough debridement is the preferred treatment due to various micro-organisms, while there is no consensus about the primary closure of the wound. Inclusion criteria are complete amputations even with bone involvement at all levels. Exclusion criteria are skeletonized distal phalangeal bone, not surrounded by soft tissues, joint involvement and exposed tendon. It offers complete regeneration of the fingertip without signs of infection, even in animal bites wounds. There are few reports in the literature regarding the semi-occlusive dressing for treating fingertip amputations-only one report uses this technique after an animal bite in a two-year-old girl. In this case report, an Allen III fingertip amputation caused by a dog bite in a 64-year-old female was managed successfully using the semi-occlusive dressing technique. At the final follow up three months after the injury, the aesthetic results were satisfactory. The fingertip with the nail complex was almost normal with no nail hook deformity. The pad skin regenerated with no signs of infection. The functional results were excellent, with no joint stiffness or disability. The sensibility was satisfactory with two-point discrimination of 4 mm, and there was no tenderness, cold intolerance, or neuroma. The patient was satisfied and able to participate in all daily activities. The semi-occlusive dressing technique is an alternative treatment option for Allen III fingertip amputations after animal bites. It promotes regenerative healing, and despite bacterial colonization, no infection has been reported.

Abstract
Arthrodesis of the first metatarsophalangeal (MTP) joint has been established as the “gold standard” for the treatment of several first ray disorders, due to its perceived efficacy and the consistently reported good results in the literature. Arthrodesis is a commonly performed procedure for the treatment of end stage arthritis, rheumatoid arthritis with severe deformity, selected cases of severe hallux valgus (with or without signs of degenerative joint disease), as well as a salvage procedure after failed previous operation of the first ray. The goals of a successful 1st MTP arthrodesis are pain alleviation and deformity correction in order to restore a comfortable gait pattern and to improve shoe wear. Several techniques have been reported with several proposals regarding the preparation of the articular surfaces and the method of definitive fixation. As with any given surgical procedure, various complications may occur after arthrodesis of the 1st MTP joint, namely delayed union, nonunion, malunion, irritating hardware, etc.

Abstract
CASE We present a case of a 35-year-old-man with a giant sclerosing epithelioid fibrosarcoma (SEF) of the thigh. The patient presented with a history of a painful thigh mass. Plain radiographs revealed a soft-tissue mass with extensive calcifications, whereas on magnetic resonance imaging, a lobulated mass between the adductors and the posterior muscles of the thigh was noted. A wide en block resection was undertaken, and the histopathology confirmed the diagnosis of SEF. Postoperative radiation therapy was followed. The patient had no signs of recurrence at the 4-year follow-up. CONCLUSION The clinicopathological, imaging characteristics, and treatment options of this rare soft-tissue tumor are discussed.

Abstract
Greece, one of the oldest civilizations of the world, fundamentally contributed to the establishment and evolution of medicine and surgery. Undoubtedly, the foundations of the orthopaedic science are dated back to antiquity. The journey of the orthopaedic art was inaugurated with the poems of Homer and incarcerated through the practices of Hippocrates and Galen. Their deep knowledge of the musculoskeletal conditions and their treatment was generously bequeathed to humanity. This heritage acted as the catalyst for the establishment of orthopaedics in the modern Greek era. In this article, we tried to illustrate the evolution of the orthopaedic art in Greece from antiquity to modern times, reviewing the available evidence from scientific articles, books, historical manuscripts, old newspapers, and biographies. We summarize the most important events, and we identify the pioneers that shaped this new surgical branch, creating the modern Greek orthopaedic discipline.

Abstract
Purpose To perform translation, cross-cultural adaptation, and validation of the Toronto Extremity Salvage Score (TESS) and Musculoskeletal Tumor Society (MSTS) scoring system in Greek patients with lower extremity sarcoma. Methods The Greek version of the MSTS for the lower extremity and TESS questionnaires was developed using previously reported methods. Included were 100 patients with musculoskeletal sarcoma who underwent limb salvage surgery. The test–retest reliability [interclass correlation coefficient (ICC) between 2 different time points], internal consistency (Cronbach’s alpha), construct validity (Kaiser’s criteria, Eigenvalue > 1 rule), and external validity (Short form-36, Spearman’s Rho) were assessed. Results The test–retest reliability (ICC was 0.99 for MSTS-LE and 1 for TESS) and internal consistency were high (Cronbach’s alpha was 0.763 for MSTS-LE and 0.924 for TESS) for both questionnaires. Based on the Scree plot, the number of factors retained was 1 for MSTS-LE and 2 for TESS. The TESS showed a strong correlation with SF-36 (Spearman’s rho = 0.714, p < 0.001), but the correlation between MSTS for lower extremity and SF-36 was weak (Spearman’s Rho = 0.313, p = 0.002). Conclusions The Greek version of both the MSTS for lower extremity and TESS questionnaire showed sufficient reliability, internal consistency and good performance using the loading factor analysis when used postoperatively in Greek patients who underwent surgical resection of lower extremity sarcoma. However, only the TESS showed strong correlation with the SF-36, indicating that MSTS for lower extremity was not as powerful for the evaluation of the global health status of these patients.

Abstract
Objectives The increasing number of hip arthroplasties (HA), due to the growing elderly population, is associated with the risk of femoral periprosthetic fractures (FPFs). The purpose of this study was to identify potential risk factors for the development of FPFs after HA. Methods A systematic review was conducted in five data bases (Medline, Embase, Cochrane, Cinahl, ICTRP) according to the Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA) guidelines up to May 2019, using the key words “risk factor,” “periprosthetic fracture,” and “hip replacement or arthroplasty.” Meta-analysis of the clinical outcomes of HA and subgroup analysis based on the factors that were implicated in FPFs was performed. Results Sixteen studies were included (sample size: 599,551 HA patients, 4253 FPFs, incidence 0.71%). Risk factors statistically associated with increased incidence of FPFs were female gender (+ 40%), previous revision arthroplasty surgery (× 3 times), and the presence of rheumatoid arthritis (× 2.1 times), while osteoarthritis (− 57%), cement application (− 59%), and insertion of Biomet (− 68%) or Thompson’s prosthesis (− 75%) were correlated with low prevalence of FPFs. Obesity, cardiac diseases, advanced age, bad general health (ASA grade ≥ 3), and use of Exeter or Lubinus prosthesis were not linked to the appearance of FPFs. Conclusion This meta-analysis suggested that female gender, rheumatoid arthritis, and revision arthroplasty are major risk factors for the development of FPFs after a HA. In those patients, frequent follow-ups should be planned. Further prospective studies are necessary to clarify all the risk factors contributing to the appearance of FPFs after HA.

Abstract
INTRODUCTION Trauma-induced coagulopathy has been extensively investigated in the multitrauma setting, but only sparsely following moderate orthopedic trauma. The purpose of this study was to evaluate changes in the hemostatic profile of patients with hip fractures, using rotational thromboelastometry (ROTEM). METHODS 198 patients with hip fractures who underwent surgery were included in the study. A matched group of 52 healthy individuals was also enrolled. Demographics, conventional laboratory assays, and ROTEM parameters were recorded and compared between patients and healthy adults. The preoperative and postoperative ROTEM values of fractured patients were also compared. RESULTS The conventional coagulation assays were similar for the 2 groups. However, several ROTEM parameters including EXTEM MCF (P < .001), EXTEM alpha angle (P < .001), INTEM MCF (P < .001), INTEM A10 (P < .001), and INTEM alpha angle (P < .001) significantly differed between the 2 groups indicating a higher coagulation potential following hip fractures. Also, fractured patients had significantly lower INTEM and EXTEM CT values (P = .008 and P = .012, respectively) and significantly lower INTEM and EXTEM CFT values (P < .001). Adjusted analysis for confounders further confirmed the direct relationship between hip fracture and higher coagulation activity. Last, INTEM CT and CFT significantly decreased (P = .008 and P < .001, respectively), while INTEM MCF, A10, and alpha angle significantly increased (P < .001) postoperatively, indicating that surgery further increases the coagulation potential. CONCLUSION A higher coagulation activity following hip fractures and surgical treatment can be detected by ROTEM shortly after the injury, even when this is undetectable by conventional coagulation assays.

Abstract
Operative treatment with tension band wiring or plate is the gold standard of care for displaced olecranon fractures. In elderly patients, multiple comorbidities combine with increased intraoperative risks, and postoperative complications may yield poor results. There are small series in the literature that show promising results with non-operative treatment. Non-operative treatment may provide reasonable function and satisfaction in the elderly population and could be considered as a treatment option in this group, especially for those with comorbidities, to avoid postoperative complications and the need for re-operation.

Abstract
Introduction: Implant-associated infections are a major problem in orthopaedic surgery. Local delivery systems of antimicrobial agents on the implant surface have attracted great interest recently. The purpose of this study was to identify antimicrobial coatings currently used in clinical practice, examining their safety and effectiveness in reducing post-operative infection rates. Materials and Methods: A systematic review was conducted in four databases (Medline, Embase, Cochrane, Cinahl) according to the Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA) guidelines up to December 2019, using the key words “orthopaedic implant coated”, “coated implant infection”, “silver coating ” and “antibiotic coating”. Results: Seven articles involving 1307 patients (561 with coated implants and 746 controls who were not) comparing the incidence of periprosthetic infections after the application of internal fracture fixation, total arthroplasties and endoprostheses were evaluated. Three different coating technologies were identified: gentamicin coating for tibia nail and total arthroplasties; silver technology and povidone-iodine coating for tumour endoprostheses and titanium implants. Meta-analysis demonstrated that patients who were treated with antimicrobial coated implants presented lower infection rates compared to controls over the seven studies (Q = 6.1232, I2 = 0.00, 95% CI: 1.717 to 4.986, OR: 2.926, Z= 3.949, p<0.001). Subgroup statistical analysis revealed that each coating technique was effective in the prevention of periprosthetic infections (Q = 9.2606, I2 = 78.40%, 95% CI: 1.401 to 4.070, OR: 2.388, Z= 3.200, p<0.001). Conclusion: All technologies were reported to have good biocompatibility and were effective in the reduction of post-operative peri-prosthetic infection rates.

Abstract
Background Osteosarcoma is a very aggressive primary bone tumour, affecting mainly young populations. Most cases diagnosed have distant macro- and micro-metastases at the time of diagnosis. Surgical resection with neoadjuvant and adjuvant therapies improves the overall and disease-free survival of patients. Doxycycline, a synthetic tetracycline, has been found to act either as an antibiotic drug or as a chemotherapeutic agent. Its anti-neoplastic role has been found to be significant, in vitro and in vivo laboratory trials, in various types of cancer, such as prostate, intestinal, central neural system cancers and osteosarcoma. Inhibition of metalloproteinases (MMPs) in different stages of tumour expansion is the most well-understood mechanism. MMPs are secreted molecules from various normal cells, such as fibroblasts, leucocytes and vascular smooth muscles, as well as from cells with high proliferative potential, such as tumour cells. In osteosarcoma, MMPs have been found to be overexpressed. MMPs help osteosarcoma cells survive, grow and produce metastases in distant sites, mainly in the lungs. Doxycycline blocks extracellular matrix and basic membrane degradation by suppressing MMP function. As a consequence, osteosarcoma cells lose their ability to invade and metastasize. Additionally, doxycycline eliminates the secretion of vascular endothelial growth factor (VEGF) and deprives the supply of circulating nutrients by its anti-angiogenesis action. The aim of this review is to evaluate doxycycline’s action against osteosarcoma cells as an MMP-inhibitor and interpret its usage as a chemotherapeutic agent. Methods We checked PubMed and Google Scholar for recently published data, on the tumour-supportive role of MMPs and VEGF in osteosarcoma cells. We further studied published experimental trials on the role of doxycycline as a tumour-suppressive agent via MMPs and VEGF inhibition. Results MMPs and VEGF have been found to play a fundamental role in osteosarcoma cells survival and high aggressiveness by in vitro, in vivo and clinical trials. Nevertheless, doxycycline has proved its tumour-suppressive effect by in vivo experimental trials in various cancers but not yet in osteosarcoma. Conclusion Doxycycline remains a promising chemotherapeutic agent against osteosarcoma via MMP inhibition, showing the need for further in vivo and clinical trials to be carried out in the future.

Abstract
Soft tissue tumours of the elbow are mostly benign. Malignant tumours in this area, although uncommon, often present unique clinical and histopathological characteristics that are helpful for diagnosis.Management of soft tissue tumours around the elbow may be challenging because of their rarity and the proximity to neurovascular structures. Careful staging, histological diagnosis and treatment are essential to optimize clinical outcome. A missed or delayed diagnosis or an improperly executed biopsy may have devastating consequences for the patient.This article reviews the most common benign and malignant soft tissue tumours of the elbow and discusses the clinicopathological findings, imaging features and current therapeutic concepts.

Abstract
Maud Forrester-Brown in the United Kingdom (1921), Marika Daniilidou in Greece (1932), Ruth Jackson in the United States (1932), Loris Figgins in Australia (1957), and Evalina Burger in South Africa (1993) all chose to specialize in orthopedics. Although there are dynamic female leaders in orthopedic surgery, the field continues to present obstacles to women. Role models, mentors, and exposure to the field have been lacking for women. Although improvements have occurred in the past few decades, further changes are necessary to attract, develop, and retain qualified female candidates. [Orthopedics. 2020; 43(1):e8-e14.].

Abstract
Treatment of bone sarcomas in children is associated with wide tumor re-section and segmental reconstruction. The optimal surgical approach is still under debate in the literature. During the past decade, the application of expandable prostheses has gained remarkable attention because it improves patients' appearance and allows limb growth preventing leg length discrepancy. A systematic review of the literature was performed to identify studies focusing on the functional and surgical outcomes of the application of expandable endoprostheses.

Abstract
Ewing's sarcoma is extremely rare in the foot. Below the knee amputation is indicated for most primary malignant bone tumors of the hindfoot, with few cases of successful limb salvage surgery having been reported. The use of 3-dimensional printed implants may successfully address reconstruction challenges after tumor resection. The authors present a case of a 30-year-old woman with a Ewing's sarcoma of the talus who underwent total talectomy and replacement of the entire talus with a custom-made 3-dimensional printed talar prosthesis.

Abstract
Considering the specific anatomic features of the foot, below-knee amputation is the treatment of choice for foot malignancies. However, advances in imaging modalities, adjuvant therapies, and improved surgical techniques have made foot salvage surgery increasingly possible. The calcaneus is an unusual location for malignant tumors, and there is limited information about foot salvage. Currently, 3-dimensional printed implants may successfully address reconstruction challenges after tumor resection. The authors present 2 patients with Ewing's sarcoma of the calcaneus who underwent total calcaneus resection and reconstruction using a custom-made 3-dimensional printed implant.

Abstract
Bone Marrow Oedema Syndrome during childhood is a rare benign transient condition without clear pathophysiology. It usually resolves after conservative treatment, but resolution may exceed up to 8 months. A 12-year-old child with bone marrow oedema of the left foot which was diagnosed by magnetic resonance imaging (MRI) is reported. She presented with a six week subacute pain and mild swelling on the dorsal surface of the foot. Routine plain radiographs, blood tests, biochemical and serological tests were normal with the exception of serum Vitamin D levels that were reduced. The management of the child included partial weight-bearing, administration of anti-inflammatory drugs and supplementation of Vitamin D due to insufficient Vitamin D intake. After six months the child did not have any clinical symptoms and MRI showed complete resolution of the oedema. This is the first report of a juvenile bone marrow oedema correlated with hypovitaminosis D that was successfully treated with Vitamin D administration.

Abstract
BACKGROUND The necessity of stabilizing the residual ulnar stump after distal ulna tumor resection remains controversial. The authors retrospectively compared the outcome of patients who underwent wide resection of distal ulna giant cell tumors (GCTs) and reconstruction with tenodesis of the extensor carpi ulnaris (ECU) or without reconstruction. METHODS Between 2007 and 2015, 9 patients (6 females, 3 males; mean age, 36.8 years; range, 24-65 years) who underwent distal ulna resection for GCT of bone were retrospectively reviewed. The mean resection length was 8.1 cm. Five patients had no reconstruction, whereas 4 patients had stabilization of the ulnar stump using ECU tenodesis. With a mean follow-up of 3.6 years (2-9 years), the functional outcome using the quick Disability of Arm, Shoulder and Hand (DASH) score; Musculoskeletal Tumor Society score and grip strength; as well as the oncological outcome were evaluated. RESULTS Musculoskeletal Tumor Society functional scores were more than 24 in 7 patients and 20 to 24 in 2 patients (mean, 27.6 or 92%). Quick DASH scores ranged from 0 to 27.3 (mean, 11.1). In both groups, similar scores were observed ( P > .5). No patient had instability or pain related to the stump. There was no ulnar translation or subluxation of the radiocarpal joint. Grip strength in the operated hand, controlled for handedness, was 11% less than in the contralateral hand, although there was no difference between groups ( P > .4). All patients were disease-free at the latest follow-up. CONCLUSIONS The distal ulna may be widely resected with or without stabilization of the residual ulnar stump, yielding satisfactory local disease control and functional outcome.

Abstract
As a result of the increasing numbers of joint replacement surgeries and other implant-associated procedures performed, the incidences of periprosthetic joint infections and osteomyelitis are on the rise. Antibiotic resistance to gram-positive species, which are mostly isolated from such infections, is a significant obstacle in clinical practice. Promising clinical outcomes have been reported with the use of novel antibiotics for patients with periprosthetic joint infections and osteomyelitis. Further research is necessary for the establishment of these novel antibiotic therapies in routine clinical practice. [Orthopedics. 2018; 41(6):323-328.].

Abstract
Malignant tumors of the scapula are rare, and limb salvage surgery after tumor resection is challenging. The authors present a series of 6 patients who were treated by total scapulectomy and reconstruction with a custom-made scapular prosthesis and a constrained reverse shoulder arthroplasty. Postoperative oncologic and functional outcomes were assessed. The mean follow-up was 37 months (range, 9-84 months). Clear surgical margins were achieved in all patients. At the last follow-up, 4 patients showed no evidence of disease and 2 had died of systemic metastatic disease. Although shoulder function was limited, all shoulders were painless and stable and the patients retained satisfactory hand, wrist, and elbow function. [Orthopedics. 2018; 41(6):e888-e893.].

Abstract
Treatment of distal humerus fractures is demanding. Surgery is the optimal treatment and preoperative planning is based on fracture type and degree of comminution. Fixation with two precontoured anatomical locking plates at 90o:90o orthogonal or 180o parallel is the optimal treatment. The main goal of surgical treatment is to obtain stable fixation to allow immediate postoperative elbow mobilization and prevent joint stiffness. Despite evolution of plates and surgical techniques, complications such as mechanical failure, ulnar neuropathy, stiffness, heterotopic ossification, nonunion, malunion, infection, and complications from olecranon osteotomy are quite common. Distal humerus fractures still present a significant technical challenge and need meticulous technique and experience to achieve optimal results.

Abstract
Hyperbaric oxygen has been used as an adjunctive measure in the treatment of chronic osteomyelitis. The aim of this systematic literature review was to analyze the outcome and the complications of hyperbaric oxygen for chronic osteomyelitis. Forty-five of 96 studies reporting the use of hyper-baric oxygen for 460 patients with chronic osteomyelitis met the inclusion criteria and were analyzed qualitatively. All patients previously received antibiotics and surgical debridement. Mixed bacterial flora was detected in most of the studies. Staphylococcus aureus was the isolated pathogen in 12 (60%) of the 20 cohort and in 4 (20%) of the 20 case studies. Adjuvant hyperbaric oxygen was effective in 16 (80%) of the 20 cohort and 19 (95%) of the 20 case studies. Overall, 308 (73.5%) of 419 patients with complete data had a successful outcome and no reported relapse. Available evidence supports a potentially beneficial role of adjunctive hyperbaric oxygen, especially in refractory cases of chronic osteomyelitis. [Orthopedics. 2018; 41(4):193-199.].

Abstract
Intervertebral discs (IVDs) are the joints of the spine, mainly consisting of extracellular matrix (ECM) with a low number of cells embedded therein. Low cellularity stems from nutrient deprivation due to the lack of blood supply, as well as from the hypoxic and hyperosmotic conditions prevailing in the tissue. Intervertebral disc degeneration (IDD) has been firmly connected with low back pain, a major age-related disease, whereas degenerated discs have been characterized by increased proteolytic activity and accumulation of senescent cells. While the catabolic phenotype of senescent IVD cells has been documented, whether this phenotype is preserved under the harsh conditions met in the IVD milieu has never been investigated. Here we showed that a combination of low glucose, hypoxia, high osmolality and absence of serum is anti-proliferative for young disc cells. In addition, we demonstrated for the first time that classical senescence markers, namely p16INK4a, p21WAF1 and ICAM-1, remain up-regulated in senescent cells under these conditions. Finally, up-regulation of the main senescence-associated ECM degrading enzymes, i.e. MMP-1, -2 and -3 was maintained in this strict environment. Conservation of IVD cells' senescent phenotype under the actual conditions these cells are confronted with in vivo further supports their possible implication in IDD.

Abstract
New 3-dimensional digital technologies are revolutionizing orthopedic clinical practice, allowing structures of any complexity to be manufactured in just hours. Such technologies can make surgery for complex cases more precise, more cost-effective, and possibly easier to perform. Applications include pre-operative planning, surgical simulation, patient-specific instrumentation and implants, bioprinting, prosthetics, and orthotics. The basic principles of 3- dimensional technologies, including imaging, design, numerical simulation, and printing, and their current applications in orthopedics are reviewed.

Abstract
Synovial sarcoma is a relatively common periarticular soft tissue malignancy, occurring mostly in the extremities of younger patients. Occasionally, diversity in its clinical features may lead to misdiagnosis and inappropriate management. The authors report herein a unique case of a patient who underwent a primary total knee arthroplasty to treat osteoarthritis. During the operation, a mass was discovered but was attributed to synovitis. Biopsy revealed a rare intra-articular synovial sarcoma. The patient underwent reoperation with wide excision and endoprosthesis placement and is disease-free at the 8-year follow-up.

Abstract
Denosumab, a human monoclonal antibody that inhibits bone resorption by binding on the receptor activator of the nuclear factor kappa-β ligand, has recently emerged as an additional option in the treatment of musculoskeletal osteolytic tumors. This article focuses on the recent literature regarding the effectiveness of denosumab in the management of giant cell tumor, multiple myeloma, aneurysmal bone cyst, and osteosarcoma. The mechanism of action of denosumab in the management of these tumors and the associated side effects are discussed in detail. [ Orthopedics. 2017; 40(4):204-210.].

Abstract
With increases in both life expectancy and the number of patients with endoprosthetic replacements, more periprosthetic fractures are expected to occur. Periprosthetic fractures related to megaprostheses present a treatment challenge, with a high incidence (one-third of affected patients) of secondary revision as a result of prosthetic loosening, infection, nonunion, refracture, or even amputation. Efforts to improve endoprosthetic reconstruction should focus on preventing postoperative complications. Understanding the causes of complications and strategies to avoid them could lead to significant improvements in implant survival, limb function, and patient outcomes. This article presents a concise review of the current literature and an algorithmic approach to reconstruction of these complex injuries. [Orthopedics. 2017; 40(3):e387-e394.].

Abstract
The reported rate of complications of reverse shoulder arthroplasty (RSA) seems to be higher than the complication rate of anatomical total shoulder arthroplasty.The reported overall complication rate of primary RSA is approximately 15%; when RSA is used in the revision setting, the complication rate may approach 40%.The most common complications of RSA include instability, infection, notching, loosening, nerve injury, acromial and scapular spine fractures, intra-operative fractures and component disengagement.Careful attention to implant design and surgical technique, including implantation of components in the correct version and height, selection of the best glenosphere-humeral bearing match, avoidance of impingement, and adequate management of the soft tissues will hopefully translate in a decreasing number of complications in the future.

Abstract
Nanomedicine is based on the fact that biological molecules behave similarly to nanomolecules, which have a size of less than 100 nm, and is now affecting most areas of orthopedics. In orthopedic oncology, most of the in vitro and in vivo studies have used osteosarcoma or Ewing sarcoma cell lineages. In this article, tumor imaging and treatment nanotechnology applications, including nanostructure delivery of chemotherapeutic agents, gene therapy, and the role of nano-selenium-coated implants, are outlined. Finally, the potential role of nanotechnology in addressing the challenges of drug and radiotherapy resistance is discussed. [Orthopedics. 2016; 39(5):280-286.].

Abstract
UNLABELLED Background The purpose of this study was to review clinical and radiographic outcomes of perilunate dislocations (PLDs) and fracture-dislocations (PLFDs) treated with external fixation and Kirschner wires (K-wires). Materials and Methods Twenty patients (18 males and 2 females) with a mean age of 38 years (range 18-59) with an acute PLD or PLFD were treated with external fixator and K-wires. There were 12 PLDs and seven transscaphoid and one transstyloid PLFDs. The median time from trauma to operation was 8 hours (range 2-12 hours). Indirect reduction via ligamentotaxis was achieved in 17 patients with a mean age of 38years (range 18-59). There were 12 PLDs and 5 trans-scaphoid PLFDs; however, in three cases (two transscaphoid and one transstyloid PLFDs), indirect reduction failed and an open reduction was required. The intercarpal ligaments were not repaired even after open reduction. Results The mean follow-up was 39 months (range 18-68 months). The flexion-extension range of motion (ROM) and grip strength of the injured wrist averaged 80% and 88%, respectively, of the corresponding values for the contralateral wrists. According to Cooney's scoring system, overall functional outcomes of the 17 patients were rated as excellent in 4 patients, good in 8, fair in 4, and poor in 1. Fifteen patients returned to their former occupations. Two patients with a trans-scaphoid perilunate injury developed nonunion of the scaphoid, and two developed posttraumatic arthritis. Conclusion External fixation plus percutaneous K-wires for the treatment of acute PLDs has satisfactory midterm functional and radiographic outcomes. When successful, this minimally invasive technique is simple and provides restoration of the carpal alignment. It may especially be useful in the polytrauma patient, thanks to its decreased operative time and diminished blood loss, when other emergent surgical procedures may be necessary. An open reduction with possible fixation may be necessary for PLDs and PLFDs, especially in the presence of polytrauma and scaphoid comminution. LEVEL OF EVIDENCE IV.

Abstract
The purpose of this study was to review clinical and radiographic outcomes of perilunate dislocations and fracture dislocations treated with external fixation and K-wire fixation. Twenty patients (18 males and two females) with a mean age of 38 years (range 18–59) who had an acute dorsal perilunate dislocation or fracture dislocation were treated with the use of wrist external fixator and K-wires. The injuries included 12 perilunate dislocations, seven trans-scaphoid perilunate fracture dislocations, and one trans-styloid perilunate fracture dislocation. The median time from trauma to operation was 8 h (2–12 h). Indirect reduction via ligamentotaxis was achieved in all perilunate dislocation, and provisional K-wire fixation was added. In five of seven trans-scaphoid perilunate fracture dislocations, indirect reduction was achieved; whereas in the other two as well as in the case of trans-styloid perilunate fracture dislocation, open reduction was required. External fixator was supplemented with K-wires for stabilization of the fractures and the intercarpal intervals. The interosseous and capsular ligaments were not repaired, even after open reduction of fracture dislocations. The mean follow-up was 39 months (range 18–68 months). Range of motion and grip strength were measured. Cooney’s scoring system was used for the assessment of clinical function. Radiographic evaluation included time to scaphoid union, measurement of radiographic parameters (scapholunate gap, scapholunate angle, lunotriquetral gap, and carpal height ratio) and any development of arthritis. The flexion-extension motion arc and grip strength of the injured wrist averaged 80 and 88%, respectively, of the corresponding values for the contralateral wrists. According to Cooney’s clinical scoring system, overall functional outcomes were rated as excellent in four patients, good in eight, fair in six, and poor in two. Eighteen patients returned to their former occupations. Two patients with a trans-scaphoid perilunate injury developed nonunion of the scaphoid; one of them required scaphoid excision and midcarpal fusion. Two patients had radiographic evidence of arthritis. The use of external fixation and provisional K-wire fixation for the treatment of acute perilunate dislocations is associated with satisfactory midterm functional and radiographic outcomes. This minimally invasive treatment option is simple, reliable, and minimally invasive method that provides proper restoration and stable fixation of carpal alignment.
