RESUMEN

Objective Obesity leads to osteoarthritis due to increased loading forces on joint cartilage and inflammatory agents released from adipose tissue. In patients with a high body mass index (BMI), during hip and total knee arthroplasty, surgical technical challenges such as longer incisions and wider exposure are encountered, resulting in increased postoperative complications (wound healing problems and infection, venous thromboembolism (VTE)- pulmonary embolism (PE), dislocation, early implant failure) and ultimately decreased patient satisfaction and implant survival. This study investigates whether BMI, height, weight, and patient age are associated with longer incisions in patients undergoing unicondylar knee prosthesis (UKP) placement. Method Between January 2017 and December 2018, 30 patients (29 females and 1 male) who underwent UKP surgery due to medial gonarthrosis were included in the study. The UKP used in the procedures was the Oxford Knee Phase III by Biomet Ltd., UK. The study comprised 43 knees, 13 being bilateral cases, 8 on the right, and 9 on the left. Data regarding the patient's height, weight, BMI, age, and the operated side were collected and compiled. The relationships between these variables and the surgical incision length were statistically analyzed. Results The average age of the patients was 66.3 years, with an average weight and height of 77.6 kg (ranging from 62 to 98 kg) and 167 cm (ranging from 150 to 184 cm), respectively. The lengths of the surgical incisions ranged from 70 mm to 160 mm, with an average length of 124.5 mm. When comparing the incision lengths between the right and left sides, it was observed that the incisions on the left side were longer. The average incision length on the right side was 122.09 mm, while on the left, it was 126.86 mm. Moreover, in the 13 patients who underwent bilateral surgery, this difference in incision length was even more pronounced. The average incision length on the right side was 117.15 mm, whereas on the left, it was 124.23 mm. Bivariate correlation analyses were performed to examine the relationship between the length of the incision and BMI and age. However, no significant relationship was found between the incision length and BMI or age. On the other hand, there was a correlation between the patient's weight values and the incision length (p < 0.05, correlation 0.335). Furthermore, a higher correlation was observed between the patient's height and the incision length (p < 0.01, correlation 0.595). Conclusion The latest advances in surgical techniques and instrumentation have enabled surgeons to perform the procedure using a reliable mini-incision approach. Mid-term evaluation of UKP with mini-incision shows faster recovery and lower morbidity. The findings show that in UKP, the length of the surgical incision is more strongly related to the patient's height than their weight.

RESUMEN

BACKGROUND: This study aims to evaluate and compare stiffness and the load to failure values of our novel medial malleolus compression plate (MP) and 3,5mm 1/3 tubular plate (TP) in the treatment of vertical shear fractures of medial malleolar fractures. METHODS: Fourteen identical synthetic third generation composite polyurethane bone models of right distal tibia were randomly separated into two groups. Fracture models were created with a custom-made osteotomy guide to provide the same fracture characteristics in every sample (AO OTA type 44A2). Fractures were reduced and novel medial malleolus compression plate was applied to bone models in MP group and tubular plate was applied to TP group. All samples were evaluated biomechanically, force/displacement and the load to failure values were recorded. RESULTS: The force required to create displacement in MP group was twice of that of the TP group. There was a significant difference between two groups in all amounts of displacement (p = .006, p = .005, p = .007 and .015 for 0.5, 1.0, 1.5, and 2.0 mm, respectively). CONCLUSIONS: In the treatment of vertical shear fractures of the medial malleolus, the strength of fixation with the novel medial malleolar compression plate is biomechanically higher than the one-third semi-tubular plate.

RESUMEN

This study aimed to examine the primary arthroplasty attitudes of Turkish orthopedics and traumatology specialists and residents to patients with intertrochanteric fractures, of various ages, comorbidity situations and fracture types, using an internet-based questionnaire. Between March and April 2021, a cross-sectional survey was conducted with a total of 159 orthopedics and traumatology specialists and residents in Turkey, using an online questionnaire that consisted of 16 different patient scenarios of varying intertrochanteric fracture types, ages, and comorbidity conditions. Respondents' preference ratio for primary arthroplasty was 24.1% in the scenarios with patients over the age of 71, while it was 8.4% in the scenarios with patients aged between 50 and 70. The ratios of primary arthroplasty preference were 12.4%, 21% and 27.3% in 2-part, 3-part and 4-part fracture scenarios, respectively. The primary arthroplasty preferences of respondents with 10 years or more of professional experience were observed to be statistically significantly different to those of the respondents with 1 to 10 years of experience in the 4-part fracture scenario where the patient was aged 71 years and above with an ASA (American Society of Anesthesiologists) score of 3-4 (p < 0.05). Despite varying opinions in the literature in recent years, primary arthroplasty can be considered a valuable alternative approach for Turkish surgeons, and in older adult patients with unstable intertrochanteric fractures, particularly those who need early mobilization and have high ASA scores.

RESUMEN

Anteroposterior (AP) lag screw, posteroanterior (PA) lag screw, or posterior buttress plate are usually performed for posterior malleolar fixation, but the biomechanically strongest technique is unclear. The aim of our study was to biomechanically compare 3 different fixation methods for posterior malleolar fractures; AP lag screw, PA lag screw, and closed-loop double endobutton. Fracture models were created using a thin blade power saw after drawing the fracture line. The resultant fracture involved 30% of the joint on the distal tibial joint surface and extends with an angulation of approximately 50 degrees using 15 tibia composite bone samples. After anatomical reduction, fixation was achieved with 3.5 mm cortical screw in PA direction and in AP direction for group PA and AP, respectively. In Group DL, fixation was achieved with a closed-loop double endobutton (double lift loop, Orthomed, Turkey). The highest compression force to generate all displacement amounts was required for the double loop group (Group DL). The strongest fixation against compression was a double loop. The PA group was the second strongest fixation, and the AP group was the biomechanically weakest among these 3 fixation techniques. The closed-loop double endobutton technique was found biomechanically superior to anterior to posterior or posterior to anterior screw fixation techniques for posterior malleolar fracture.

RESUMEN

An 84-year-old male patient with no known comorbidity was admitted to the emergency department with complaints of dyspnea and respiratory distress. The patient was referred to the COVID outpatient clinic, laboratory and radiology tests were performed. Thoracic CT scan of the patient showed large peripheral patchy ground glass densities observed in the lower lobes of both lungs. CT imaging findings were evaluated by an experienced radiologist and reported as COVID-19 pneumonia. The patient, who was self-isolated at home for 5 days, presented to the emergency department again on the fifth day with complaints of respiratory distress, fever, bruising with cough, and loss of peripheral pulse in the left lower extremity. Necessary tests were performed on the patient. An above-knee amputation was performed when a diagnosis of limb ischemic necrosis was made and no revascularization attempt was considered by the CVS department. This case study describes the coexistence of sudden lower extremity thrombosis and Covid-19 in our case without a known chronic disease.

RESUMEN

OBJECTIVE: The aim of this study was to show whether local application of cadmium-impregnated bone cement can induce apoptosis and decrease the viability of residual osteosarcoma (OS) cells in nude mice. METHODS: K7M2 tumorigenic OS cell line was cultivated in vitro. The xenograft tumor model was formed by subcutaneously adding the tumor cells to athymic nude mice. Tumor was formed within 1 month. Then, mice were randomly assigned to five groups, each containing seven nude mice: control (group 1), wide resection (group 2), intralesional resection (group 3), intralesional resection + bone cement (group 4), and intralesional resection + cadmium embedded in bone cement (group 5). Tumor resection with 1 cm surgical margins was performed in the wide resection group. In intralesional resection groups, tumor tissue was resected with positive margins aiming to leave 15 mm3 of macroscopic tumor tissue. In group 3, the defect was left empty; groups 4 and 5 received bone cements prepared with saline and cadmium solutions, respectively. After the resection, mice were observed for 15 days and sacrificed. Next, surgical resection sites were evaluated histopathologically in each group. RESULTS: Recurrent tumor was formed in all mice in the wide resection group, and apparent progression of residual tumor was observed in groups 3 and 4. On the contrary, only a thin layer of residual tumor was observed around the bone cement in group 5. Histological evaluation revealed remarkable necrosis in group 5 and lowest viability compared to other groups. No systemic toxic effect related to cadmium was observed. CONCLUSION: Our data suggest that local application of cadmium in bone cement has a significant potential to increase tumor necrosis and decrease the viability of residual OS cells.

RESUMEN

Objective To compare results of two different frequencies and densities of radial extracorporeal shock wave therapy (rESWT) after 10 sessions. Methods A total of 41 patients with plantar fasciitis were included in this study. Patients were randomly divided into two groups. Both groups were administered 10 sessions of treatment consisting of 15 Hz frequency, 3.0 Bar density and 2000 impulses/ session for the 1st group, and 10 Hz frequency, 2.0 Bar density and 2000 impulses/ session for the 2nd group. Visual analog scale (VAS) and a modification of the clinical rating system of the American Orthopedic Foot and Ankle Society (AOFAS) were used for outcome measurement. The patients were assessed before treatment and followed up four weeks, and 12 weeks after end of treatment. Results Mean VAS scores were reduced after rESWT from 7.52 ± 2.34 (mean ± SEM) at baseline to 0.57 ± 0.68 at 12 weeks in the 1st group and from 6.45 ± 2.04 at baseline to 0.40 ± 0.60 at 12 weeks in the 2nd group. Similar changes were found for mean AOFAS scores from baseline after rESWT but were not observed significance between groups. Conclusion There is no significant different effect between the two treatment groups' results.

RESUMEN

OBJECTIVES: This study aims to evaluate the cosmetic and functional results of suture treatment on pincer nail deformity (PND). PATIENTS AND METHODS: This study was conducted between June 2018 and November 2018. Sixteen nails of 13 patients (6 males; 7 females; mean age 46.9 years; range, 24 to 74 years) with PND were treated with silk sutures. The pathologic stage (including tissue status and level of pain), visual analog scale (VAS), nail height (H) and width (W) were evaluated pre- and postoperatively. Nail H and W were measured pre- and postoperatively from digital photographs of each nail and H/W ratio was calculated. RESULTS: The postoperative VAS, severity of pain scores, and nail H showed a significant decrease compared to the preoperative values (p<0.05). Curvature of the nail and pain scores decreased in all patients. Nail W showed a significant increase, therefore H/W ratio decreased significantly (p<0.05). Although recurrence of cosmetic deformity was seen at six months, the VAS and tissue scores remained lower than preoperative values. Patients reported favorable outcomes compared to their preoperative complaints. CONCLUSION: The described suture treatment method is an inexpensive, simple technique, not requiring any special material. These results support that this technique is useful for pain relief and tissue healing even if cosmetic recurrence occurs.

RESUMEN

OBJECTIVES: This study aims to analyze the musculoskeletal injury types, injury mechanisms, treatment modalities, complications, and costs of 67 consecutive soldiers wounded in the battlefield in Syria civil war over a period of three months. PATIENTS AND METHODS: This retrospective study was conducted between January 2018 and March 2018 at Kilis State Hospital. The study included 67 male patients (median age 28.5 years; range, 15 to 46 years). Patients' ages, injury mechanisms, fracture types, fracture locations, injury severity scores, mangled extremity severity scores, complications, and treatment costs were evaluated. RESULTS: Twenty-three patients were injured due to handmade explosives, 21 patients due to gunshots, 16 patients due to landmines, five patients due to rockets, and two patients due to grenades. A total of 35.8% of the patients (n=24) had concomitant trauma. The mean hospitalization period was 10.2 days (range, 1-45 days). A total of 88 treatments were performed on these patients. Thirty-six of these treatments were external fixators, 21 were amputations, 12 were open reduction internal fixations, seven were closed reduction internal fixations, five were intramedullary nailings, three were cannulated screws, three were fasciotomies, and one was an arthrodesis. The treatment costs ranged from 1,577 to 296,286 Turkish Liras. Complications were observed in 17 patients and 11 of them developed infections, three of them had compartment syndrome, and three died during the hospitalization period. CONCLUSION: The increase in warfare technology is correlated with the severity of military injuries in the battlefields. These injuries still lead to high traumatic amputation rates, high-risk complications, and high costs.

RESUMEN

BACKGROUND: High-energy traumas are common occurrences worldwide. The rate of overlooked neck fractures in polytrauma cases is also high. Previous studies have shown that articular hip pathologies, particularly neck fractures, are associated with fractures of the femoral shaft. This study sets out to describe cases of intra-articular hip pathology following traumatic femoral shaft fracture. Thus, the present study aims to investigate the relationship between ipsilateral hip pain and femoral shaft fractures. METHODS: Patients who were diagnosed with a fracture of the femur shaft and who were operated on (intramedullary fixation or plate) were included in this study. Patients with pathologic fractures, femoral neck fractures, femoral intertrochanteric fractures, or pelvic fractures were excluded. Patients with at least six months of follow-up and who were capable of independent walking without support were grouped according to AO/OTA fracture classification. Patients were questioned for deep anterior groin pain, and physical examination tests and hip imaging (X-ray and MR arthrography) were performed by calling patients with the indicated complaints. RESULTS: The presence of labral tears were noted in two patients. The incidence of osseous bump of the femoral neck identified by MR arthrography (MRA) was found in three of 16 hips. Assessment of the presence of gluteal tendinosis or tear and herniation pit identified three of 16 hips. The presence of osteophytes was noted in one patient. MRA identified three of 16 hips with more than one type of intra-articular pathology. Two patients with an osseous bump of the femoral neck were also diagnosed with additional hip pathology as herniation pit. CONCLUSION: Anterior groin pain in patients with a history of femoral shaft fracture is not always related to implants. Orthopedic surgeons should become suspicious in cases of intra-articular hip pathology in patients who have persistent hip pain after severe lower extremity trauma.

RESUMEN

Proximal fibular osteotomy (PFO) is a simple, easy and cheap procedure consisting of removing a 10 mm piece of fibula 6 to 9 cm below the fibular head. Proximal osteotomy of the fibula weakens the lateral fibular support and leads to a correction of the varus deformity and provides a widening on the medial joint space. Unicondylar knee arthroplasty (UKA) is intended to treat isolated medial compartment arthritis. However, knees with a varus deformity and tight medial joint space might cause both technical difficulties and poorer outcomes. A 68-year-old female with complaints of pain on the medial side of both knees for more than two years underwent bilateral UKA. While inserting the trial meniscal bearing was not easy due to the varus tight knee, at that stage, instead of performing a deeper cut, a PFO procedure was considered which provided widening of the medial joint space. We report, to our knowledge, the first simultaneous application of these two procedures. Despite being a single case with very short term results, our results suggest that the combination of PFO and UKA may reduce the loads over the implants on the medial compartment based on the widening of the joint space and varus deformity correction.

RESUMEN

Total knee arthroplasty (TKA) can become impaired in the functionality of the bone-prosthetic unit for various reasons, thereby leading to prosthetic loosening. For patients with bilateral aseptic loosening, revision knee arthroplasty surgery is usually performed in different sessions. Today, with developing anesthetic techniques, the patients' intraoperative and postoperative additional medical treatment needs are reduced; there is a reduction in complication rates too. Complications such as laryngospasm, bronchospasm, malignant hyperthermia, respiratory depression, postoperative delirium, or cognitive dysfunction can be seen. In the postoperative period, patient satisfaction, with adequate pain control, makes the rehabilitation of the knee is easier and shortens the duration of hospital stay. In addition, the risks of complications such as deep venous thrombosis, pulmonary embolism, pneumonia, and urinary retention are decreased with early rehabilitation, preventing the development of arthrofibrosis. Maximum recovery in the early postoperative period may be possible with the early recovery of movement. Between the years 2017 and 2018, patients admitted to our hospital for bilateral TKA application due to bilateral aseptic loosening and the early results of the application of bilateral revision TKA in one session with four selected patients are compared according to the requirements for blood transfusion and overall costs. Patient selection was shared with the anesthesiologist and the decision to continue bilaterally was made in the intraoperative assessment. In patients who did not develop any pathologies in the initial operation, the second operation was performed, where the risks of the second operation were not taken into account. As a result, we conclude that bilateral revision TKA application on correct patient selection is a surgical procedure that can be performed safely by an experienced team.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the meniscal regeneration and arthritic changes after partial meniscectomy and application of either polyurethane scaffold or novel multilayer meniscal scaffold in a rabbit model. METHODS: Sixteen NewZealand rabbits were randomly divided into three groups. A reproducible 1.5-mm cylindrical defect was created in the avascular zone of the anterior horn of the medial meniscus bilaterally. Defects were filled with the polyurethane scaffold in Group 1 (n:6) and with novel multilayer scaffold in Group 2 (n:6). Rabbits in Group 3 (n:4) did not receive any treatment and defects were left empty. All animals were sacrificed after 8 weeks and bilateral knee joints were taken for macroscopic, biomechanical, and histological analysis. After excision of menisci, inked condylar surfaces and tibial plateaus were evaluated for arthritic changes. Digital photographs of excised menisci were also obtained and surface areas were measured by a computer software. Indentation testing of the tibial condyles and compression tests for the relevant meniscal areas was also performed in all groups. Histological analysis was made and all specimens were scored according to Rodeo scoring system. RESULTS: No signs of inflammation or infection were observed in any animals. A significant difference was observed between meniscus surface areas of the multilayer scaffold group (20.13 ± 1.91 mm2) and the group with empty meniscus defects (15.62 ± 2.04 mm2) (p = 0.047). The results of biomechanical compression tests revealed a significant difference between the Hayes scores of the second group (1.728) and the empty defect group (0,467) (p = 0.029). Intact meniscal tissue showed higher mechanical properties than all the defected samples. Multilayer scaffold group demonstrated the closest results compared to healthy meniscus tissue. Tibia indentation tests and histological evaluation showed no significant differences between groups (p = 0.401 and p = 0.186 respectively). CONCLUSIONS: In this study, the initial evaluation of novel multilayer meniscal scaffold prevented the shrinkage that may occur in the meniscus area and demonstrated superior biomechanical results compared to empty defects. No adverse events related to scaffold material was observed. Besides, promising biomechanical and histological results, comparable to polyurethane scaffold, were obtained.

RESUMEN

To date, all the authors who have recommended external rotation osteotomy (ERO) in the late treatment of obstetrical brachial plexus palsy (OBPP), have neglected upper limb length discrepancy, which is an another sequelae of OBPP. In this paper, a new technique is reported for the late treatment of OBPP patients with upper limb length discrepancy, in which both humeral external rotation osteotomy (ERO) and lengthening are applied with an intramedullary elongation nail. With this technique, upper limb function is improved through re-orientation of the shoulder arc to a more functional range, and further improvements will be seen in the appearance of the upper limb with the elimination of length discrepancy. It is also advocated that there is a potentiating effect of the humeral lengthening on shoulder movements gained by ERO when the osteotomy is applied above the deltoid insertion, as this allows more lateralized placement of the deltoid insertion.

RESUMEN

OBJECTIVE: The aim of this study was to measure the area of iliopsoas tendon attachment and the distance of sciatic nerve, medial circumflex femoral artery (MCFA) and quadratus muscle to lesser trochanter tip, before and after 5, 10, 15 mm depth excision of lesser trochanter. METHODS: A total 15 hips of 8 adult male cadavers were evaluated. Distances between lesser trochanter tip, sciatic nerve, the lower edge of quadratus muscle and MCFA; length and width of quadratus muscle insertion; area of iliopsoas muscle and quadratus muscle insertion was measured before and after sequential 5,10 and 15 mm depth trochanterplasties using 5 mm wide burr parallel to the posterior cortex. RESULTS: Each incremental 5 mm depth bone removal led to significant decrease of tendon area (p=0.001) at each stage. Mean decreases of iliopsoas tendon attachment area with incremental 5 mm burring were 22%±10 with 5 mm, 50%±13 with 10 mm, and 76% ±13 with 15 mm of burring. CONCLUSION: Up to 15 mm lesser trochanter removal did not result in complete detachment of the iliopsoas tendon. Lesser trochanter tip was detected at least 20 mm away from important anatomic structures including quadratus tendon, sciatic nerve, and the medial circumflex femoral artery.

RESUMEN

OBJECTIVE: Cylindrical grafts are currently used to cover defected area in mosaicplasty. However, there are some difficulties with cylindrical grafts, such as potential dead space between grafts and insufficient coverage. Hexagonal graft (honeycomb model) was created and evaluated in this biomechanical study. Hypothesis was that harvesting grafts with hexagonal shape, which has the best volume geometry characteristics in nature, would be biomechanically advantageous and provide superior pull-out strength. METHODS: Total of 24 fresh calf femurs were divided into 3 equal groups. In the first group, 1 cylindrical and 1 hexagonal graft were compared. Second group consisted of 3 cylindrical and 3 hexagonal grafts. Third group was designed to evaluate effect of graft depth; hexagonal graft implanted at 5 mm depth was compared with 20-mm-deep hexagonal graft. All specimens were subjected to pull-out test. Friction field and graft surface area were also evaluated. RESULTS: Pull-out strength comparison of 15-mm-deep triple cylindrical grafts and 15-mm-deep triple hexagonal grafts in second group revealed statistically significant difference in favor of hexagonal grafts (p < 0.05). Surface area of cylindrical graft with 9-mm diameter was calculated to be 50.27 mm2, while hexagonal graft surface area was 55.425 mm2. Volume ratio of cylindrical and hexagonal grafts was 753.98 mm3 and 831.375 mm3, respectively. CONCLUSION: This biomechanical study demonstrated that graft geometry, especially in multiple graft applications, is a factor that influences stability. Hexagonal grafts appear to be more stable than cylindrical grafts in multiple applications, and they may be used to cover a larger defected area.

RESUMEN

INTRODUCTION: Arthroscopic fixation of tibial spine fracture without damage to the growth plate is very important in patients with open physis. The present article describes a simple and effective technique being used for the first time to treat this condition. CASE REPORT: A 16-year-old boy sustained avulsion fractures of tibial spine while playing. He was treated arthroscopically with excellent result. CONCLUSION: Arthroscopic fixation of tibial spine fracture in patients with open physis with two cannulated screws perpendicular to each other is a very simple technique which provides strong construct, and allows early mobilization without risk of damage to the growth plate.

RESUMEN

Aim of the study was to review the radiological, clinical results of 11 chondroblastoma cases treated at our institute between 2003-2013. All patients with chondroblastoma included in this study underwent intra-lesional curettage+/-bone grafting. Follow up for healing of chondroblastoma lesions and detection of any local recurrence was assessed on clinical and radiological bases. The functional outcome was assessed by the Musculoskeletal Tumour Society scoring system. The mean follow-up period was 6.1 years. There were three recurrences (two femoral head, one proximal tibia). The mean Musculoskeletal Tumour Society functional score was 21. First line aggressive treatment seems appropriate for chondroblastoma especially when localized at lower extremities.

RESUMEN

Scapular dislocation, also known as locked scapula or scapulothoracic dislocation, is a rare entity that can be identified as extrathoracic or intrathoracic dislocation, depending on the penetration of the scapula into the thoracic cavity. The 3 reported cases of intrathoracic scapular dislocations in the literature are associated with a preexisting condition, such as sternoclavicular separation, prior rib fracture, thoracotomy for a lung transplant procedure, or surgical resection of superior ribs during breast or pulmonary tumor excisions. There are also 3 published cases of intrathoracic scapular impaction, involving comminuted scapular fractures with intrathoracic impaction of the inferior fragment through intercostal space. We report an intrathoracic scapular dislocation that was not associated with fracture of the scapula or predisposing factors. To our knowledge, this is the first case of pure intrathoracic dislocation.
