Comparison of SHD-IBG and PVIBGT in ONFH including mechanical and pathological analysis of failure cases

Currently, there is a lack of relevant research on the efficacy difference between SHD combined with IBG and PVIBGT in the treatment of osteonecrosis of the femoral head(ONFH). Firstly, this study intends to compare the effectiveness of surgical hip dislocation combined with impacting bone grafts (SHD-IBG) and pedicled vascularised iliac bone graft transfer (PVIBGT) in treating ONFH. And the study investigates patients who suffered from hip preservation failures from both groups to better comprehend failure reasons. 30 patients (34 hips) with ARCO stage IIIA femoral head necrosis were selected between January 2012 and July 2022. They were divided into group A(SHD-IBG) and group B (PVIBGT) according to different surgical methods. Firstly, compared the 1-year effect between SHD-IBG and PVIBGT at 1 year postoperatively; Secondly, assessed the medium and long-term efficacy of SHD-IBG hip preservation treatment; Lastly, based on study of the femoral head removed from patients with hip preservation failure in the two groups, the reasons for the failure of hip preservation were comprehensively analyzed in the two groups. Group A: 11 males (13 hips), 4 females (4 hips);Group B: 9 males (11 hips), 6 females (6 hips).Firstly, the average Harris scores of the two groups at 1 year after surgery: preoperative: 70.7, 1 year after surgery: 78.9 in group A; preoperative: 69.5, 1 year after surgery: 81.5 in group B. The differences were statistically significant (P < 0.05).Compared to the preoperative period, quantitative analysis by DCE-MRI showed an increase in perfusion in the necroticarea and an improvement in hyperperfusion in the repair-responsive area one year after the surgery. Secondly, in group A, the hip preservation rate was 88.2% at 2.5–11 (average of 77 months) years of follow-up, and the mean Harris score at the last follow-up was 73.2.Semi-quantitative analysis of postoperative DCE-MRI showed that the perfusion curves of necrotic and repaired areas were similar to those of the normal area. This suggests the instability within the femoral head had been effectively improved, and the perfusion had partially recovered. Thirdly, according to Micro-CT and pathologica studies of patients with hip preservation failure in these two groups, all these patients' femoral head was significantly collapsed and deformed. Their trabeculae was thin and partially disorganized, with fractures in the subchondral bone and separation of the cartilage from the subchondral bone. The necrotic areas had sparse trabeculae, disorganized arrangement, loss of continuity, and disappearance of cells in the trabecular traps. The necrotic area was covered with fibrous tissue, and partial restoration was observed in the repair area. Mechanical finite element analysis showed that the maximum equivalent force was observed in the weight- bearing area and the cortical bone surrounding the shaft of femurand. The result of DCE-MRI showed that the repair reaction area exhibited abnormal hyperperfusion. In this study, the efficacy of SHD-IBG and PVIBGT was compared at 1 year after operation, and the long-term follow-up of SHD-IBG was 2.5–11 (mean 77 months) years, combined with DCE-MRI results, we found that the short-term effect of PVIBGT was more significant than that of SHD-IBG. SHD-IBG can achieve satisfactory hip preservation in the medium and long term follow-up.

The initial results of developmental dysplasia of the hip treatment by total hip arthroplasty

Objective: Comment on the initial results of developmental dysplasia of the hip treatment by total hip arthroplasty. Subject and method: This is a clinical descriptive study, with vertical follow-up and no control group study. 6 patients, including 5 females and 1 male, with developmental dysplasia including 6 hips were operated with total hip arthroplasty at the Joint Surgery Department of 108 Military Central Hospital from April 2018 to July 2022. The age range was 22 to 59 (average 39.1). The mean follow-up period was 37.5 months (ranged from 9 to 60 months). Result and conclusion: The average Harris score post-operation was 89.8 ± 7.1, significantly improved compared to 33.7 ± 4.7 pre-operation. 5/6 of cases used cement-less cup, 1 case used a compound of cement and liner polyethylene directly to the acetabulum. 1 case we had to perform proximal femur shortening. Three patients complained about limb length discrepancy. Two patients suffered temporary sciatic nerve paralysis post-operation.

Evaluation of patients' post-operative results operated for hip fracture with computerized dynamic posturography: Proximal femoral nailing versus hip arthroplasty.

Proximal femoral nailing (PFN) and hip arthroplasty (HA) are the two most often utilized surgical procedures for treating hip fractures in older patients. The post-operative postural balance and functional outcomes of patients may be significantly influenced by the technical distinctions between PFN and HA. This will influence the surgeon's preferred course of therapy. To examine the functional outcomes of patients treated with PFN and HA following a hip fracture, this study used computerized dynamic posturography (CDP). The aim of that study was to evaluate how the two treatment modalities affected patients' post-operative balance, postural stability, and functional rehabilitation. A total of 26 patients who underwent proximal femoral surgery (15 patients PFN [58%] and 11 patients HA [42%]) due to hip fractures were evaluated at least 12 months postoperatively. They were tested by direct radiographs, hip joint examinations, Harris hip score (HHS), and CDP. Twelve (46%) of 26 patients were male and 14 (54%) were female. The mean age of the participants in the study was 67.9±14.2 years. The mean follow-up period was 24 (12-44) months. The average Harris score of PFN group was 79.3 (46.8-100) points and HA group was 83.7 (61.9-99.9) points. There was no significant difference between the groups in terms of Harris Score (P=0.54). The average of the mixed value of the balance results obtained with CDP (the Composite score) for PFN group was 70.5 (56-79) points, and for HA group was 71.9 (56-83) points. There was no significant difference between the groups in terms of the Composite Score (P=0.47). Accordingly, 12 (80%) of the patients who underwent PFN had good results and 3 (20%) of them had bad results. Eight (72.7%) of those who underwent HA had good results and 3 (27.3%) had bad results. There was no statistically significant difference (P=0.66). Comparing the composite score for balance results and HHS results for rehabilitation with the data of the patients who underwent PFN and HA, there was no statistically significant difference between these two techniques in terms of postural stabil-ity and balance as a result of CDP examination.

Outcomes of osteoporotic intertrochanteric fractures treated with cement-augmented proximal femoral nail

Background/Aim: Implant failure due to poor bone quality in osteoporotic intertrochanteric fractures increases mortality and morbidity, leading to secondary surgery and complications in patients. Our study aims to evaluate the early functional and radiologic outcomes and complications of osteoporotic intertrochanteric fractures using a cement-augmented proximal femoral nail design. Methods: This case series included 24 patients AO (Arbeitsgemeinschaft für Osteosynthesefragen type 31-A2.2 in 10 patients, A2.3 in 7 patients, 31-A3.1 in 4 patients, and A3.2 in 3 patients). Proximal femoral nail cement augmentation was invariably accomplished by injecting polymethylmethacrylate (PMMA) cement into the femoral head. The clinical outcome was rated using the Harris Hip Score (HSS) at the time of the final follow-up. The results were recorded as excellent (score &gt;90), decent (score 89–70), and poor (score 70–0). Radiographs were reviewed for implant failure and union. Implant failure was defined as lag screw cut-out or perforation. Results: The average age of our sample was 73.8 (6.9) years, And the mean follow-up time was 13.6 months. In all patients, union was accomplished. Implant failure and cut-out were not observed in any of the patients. The average Harris score at the final follow-up was 80.6. According to the HSS, four patients had excellent, 15 had good, and 5 had poor functional results. Conclusion: Cement-augmented femoral nails can be used safely with a low complication rate in osteoporotic intertrochanteric femur fractures. In future studies, controlled studies should be conducted for this nail design.

Outcomes of Revision Hip Replacement After Resection Arthroplasty With a Non-Free Muscle Flap Transfer for Difficult-To-Treat Periprosthetic Infection

Background. Resection arthroplasty with non-free muscle flap transfer allows to quickly eliminate the infection, but resulting in functional impairment of hip joint. To date, there are only a few publications with a small number of observations, where the proportion of patients who underwent the second stage of the revision hip arthroplasty (rTHA) is extremely small.&#x0D; The aim of the study was to evaluate the effect of resection arthroplasty on the functional outcomes and incidence of adverse outcomes in patients with difficult-to-treat (DTT) periprosthetic infection who had previously undergone resection arthroplasty with a non-free transfer of the axial flap fom the vastus lateralis muscle.&#x0D; Methods. The prospective study included 24 patients. During the period 20112021, at the first stage of the treatment for chronic recurrent DTT PJI of the hip, resection arthroplasty was performed with a non-free transfer of an island flap from the vastus lateralis muscle. Subsequent reimplantation of the endoprosthesis was performed in at least 1 year after the infection remission. The functional outcomes, degree of the lower limb shortening immediately before and in two or more years after revision arthroplasty (rTHA), the results of the microbiological cultures at the first and second stages of PJI treatment, technical aspects of the surgery as well as the postoperative period and long-term PJI remission were studied.&#x0D; Results. Revision arthroplasty resulted in a statistically significant improvement of the postoperative functional outcome and quality of life in patients. The average Harris score agter rTHA increased from 53 to 83 points after surgery, EQ-5D degree of the quality of life increased from 50 points to 80, the overall score from 0.61 to 0.74 and average intensity of pain via VAS decreased from 3 points to 1 point in 3.1 years after rTHA (p0.05). After reEP, complete restoration of the limb length was achieved in 29.1% of cases (n = 7) with an average compensation of the limb length for 4.5 cm. In 66.7% of patients (n = 16), the results of the intraoperative tissue biopsy microbiological analysis during reEP were culture negative. The recurrence rate of PJI was 12.5% (n = 3) up to 30 days after rTHA and 4.2% (n = 1) with a follow-up period of 3.1 years (IQR 2.14.1). With a single revision surgery performed without a delay, stable remission of DTT PJI was 95.8%.&#x0D; Conclusion. Complex two-stage surgical treatment using resection arthroplasty with a non-free muscle flap transfer at the stage of debridement and subsequent revision has demonstrated high efficiency in eliminating the infectious process as well as restoring weight-bearing capacity and extremity function. It could be recommended as a method of choice in the treatment of patients with DTT PJI of hip joint.

Management of Neglected Femoral Neck Fracture in Young Adolescents with Modified Pauwels Osteotomy

Background: Non-union of the femoral neck fracture in young is difficult to tackle. Many reported treatment methods for neglected femoral neck fractures do not always satisfactorily address the problems like non-union, coxa vara, and limb shortening. If the femoral head is viable, the most appropriate treatment is valgus osteotomy, which increases the femoral neck angle to change shearing force to compression force. We prospectively reviewed the functional outcome of the modified Pauwels’ osteotomy in 16 young adults to determine whether this approach would correct those problems. Materials and Methods: A total of 16 cases of neck femur fracture in less than or equal to 16 year old neglected for more than 12 weeks were included in our study and were treated primarily by modified Pauwels intertrochanteric osteotomy with internal fixation. The patients were followed up to 12–24 months with radiography and were assessed regarding Harris hip score, unionand limb length discrepancy. Results: Union was seen in all the 16 patients .11 out of the 16 patients showed excellent clinical outcome (Harris hip score ≥ 90) with an average Harris score of 90.1 ± 6. Conclusion: Modified Pauwels’ Intertrochanteric Osteotomy is a safe and effective procedure in preserving the God gifted hip in neglected femoral neck fracture

New adjustable modular hemipelvic prosthesis replacement with 3D-print osteotomy guide plate used in periacetabular malignant tumors: a retrospective case series

BackgroundPeriacetabular malignant tumor seriously endangers the life and health of patients. Hemipelvic replacement provides a good method for patients who want complete resection of the tumor while retaining or restoring the function of the affected limb.ObjectiveTo investigate the performance and clinical application of the new adjustable modular hemipelvic prosthesis and to compare the effects of three kinds of hemipelvic prosthesis.MethodsIn this study, 23 patients, with an average age of 44.6 years (21–75 years), were collected, who received hemipelvic replacement with new adjustable, modular, and screw-rod system hemipelvic prosthesis. Preoperative preparation was conducted on them, and operative complications were recorded. Postoperative functional follow-up was performed regularly.ResultsThe average operation time was 319 min (170–480 min), and the average blood loss was 2813 ml (1000 mL-8000 ml). The incidence of complications was 47.8%, and type A (wound-related complications) had the highest incidence (34.8%). Postoperative dislocation occurred in 3 cases (13.0%), and no dislocation occurred in the new adjustable modular hemipelvic prosthesis group. The average MSTS score of the patients was 18.6 (10–23), and the average Harris score was 73.7 (53–87).ConclusionsThe new adjustable modular hemipelvic prosthesis has the feasibility of reconstruction and good functional outcome, making it ideal for periacetabular tumors. Furthermore, preoperative tumor-feeding artery embolization and abdominal aortic balloon implantation may be an effective choice to reduce intraoperative blood loss and facilitate the operation of tumor resection.

Koksartrozlu Kalçada Gelişen Kompleks Asetabuler Kırığın Tedavisinde Erken ve Geç Dönem Artroplasti Sonuçlarinin Değerlendirilmesi

Purpose: We aimed to compare the clinical results of patients who underwent early and late hip arthroplasty due to complex acetabulum fracture with coxarthrosis and investigate the factors affecting the clinical results. Method: Patients who were operated on for acetabular fractures between 2005 and 2017 were retrospectively analysed. Patients with complex fractures according to the Letournel Classification and arthrosis according to the Kellgren-Lawrence radiological criteria were included in the study. Patients were divided in to two groups, post-fracture early period (group 1) and late period (group 2), based on when they underwent arthroplasty. Both groups were compared in terms of Harris hip score, Visual Analogue Scale (VAS), age, arthrosis, operation time, and time to return to daily life. Result: It was determined that 20 of the patients included in the study underwent arthroplasty in the early period and 21 in the late period. The mean average Harris score was 71.60 (± 13.5) in those who underwent early arthroplasty and 61.23 (± 2.6) in those who underwent late arthroplasty (p = 0.002). The average VAS score was 1.7 (1–3) in those who underwent early arthroplasty and 2.6 (1–5) in those who underwent late arthroplasty (p= 0.102) Conclusion: Early arthroplasty is a safer option with better functional results and lower complication rates than late arthroplasty in patients with complex acetabular fractures with coxarthrosis. In patients with complex acetabular fractures with coxarthrosis, early arthroplasty should be preferred when the surgeon is not sure about early or late arthroplasty. Keywords: Acetabular fracture, coxarthrosis, total hip replacement.

Objective. To study the results of pre-differentiated MSCs application in the treatment of femoral head necrosis in young patients. Methods. The developed high-tech approach included: exfusion of 50-70 ml of patient’s bone marrow 4 weeks prior to implantation; osteogenic differentiation and obtaining a biomedical cell product; surgical decompression and introduction of pre-differentiated MSCs in fibrin gel; postoperative rehabilitation. Surgeries were performed in 25 patients at stages I and II according to the ARCO classification. The average age of patients is 34 [29; 45], men - 20 (80%), women - 5 (20%). Theassessment scaleis avisual analogue scale (VAS), Harris scale, radiography, MRI. Results. Observation period was 41 [19; 59] month. Average Harris score before surgery was 76 [68.8; 79] points, after treatment - 90 [78.9; 92] points. In 15 (60%) cases an excellent results were obtained, in 5 (20%) - good, in 3 (12%) - satisfactory, in 2 (8%) - unsatisfactory (collapse progression). The level of pain syndrome was reduced from 40 [30; 50] to 10 [5; 25] points. There were no complications. Preservation of the femoral head sphericity and the width of the joint space, relief of bone marrow edema, reduction of the necrosis zone size and synovitis according to MRI data were found in 92% of cases. Conclusion. The treatment method of femoral head necrosis with the use of pre-differentiated MSCs in the absence of infectious triggers in the lesion focus made it possible to preserve 95 % of cultured cells in the cell product composition and to introduce it minimally invasively, avoiding the need for bone graft collection. The introduction of the cellular technologies in practice made it possible to obtain positive treatment results in 92% of cases due to an improvement clinical condition by the Harris scale and reduce of pain syndrome compared to the initial state; it did not lead to infectious, allergic or other complications within the 41 [19; 59] month follow-up. What this paper adds A method of cell therapy of femoral head necrosis affected young patients using pre-differentiated mesenchymal stem cells (MSCs) has been firstly developed. The use of a new method of treatment made it possible to obtain positive results and preserve the structures of the hip joints in 92% of cases due to the optimization of the osteoregeneration process has been demonstrated.

OUR EXPERIENCE IN HARDING AND «BIKINI» APPROACHES AT TOTAL HIP ARTHROPLASTY

Total hip arthroplasty is widely spread in all over the world medical practice. Different approaches are used for that procedure. Objective. To analyze the advantages and disadvantages of` «Bikini» approachand compare them to the Harding approach in patients after total hip arthroplasty. Methods. Тhe results of treatment of 108 patients were retrospectively analyzed: 41 patients were operated with «Bikini» approach, 67 — with Harding approach. Total hip implant with ceramic-on-ceramic, ultra-high molecular weight polyethylene-on-ceramic, and ultra-high molecular weight polyethylene-onmetal movement pair were used, also were used both cemented and cementless types of fixation. Results were evaluated on 14 day and 3 months after the surgery by Harris scale. Results. 14-day of followup the average Harris score value in patients operated with Harding approach were 74.87 points, in patients operated with «Bikini» approach — 80,55 points, on the 3rd month of follow-up period the Harris score was 78.24 and 83.9 respectively. Conclusions. Both evaluated approaches have their own advantages and disadvantages, instruments and surgeon skills requirements. Proper utilization of the «Bikini» and Harding approaches provides good functionalresults in early and late terms. «Bikini» approach requires a larger volume of preoperative preparation. The absence of fascia lata andperiarticular muscles injury due to the «Bikini» approach usage allows reducing of narcotic analgesics prescriptions, intraoperative blood loss and duration of walking with crutches. Good cosmetical scars effects are achieved by the parallelism of skin incision relatively to Langer’s lines. In the early postoperative period the better functional results were marked, early rehabilitation and mild pain syndrome allow to reduce hospital length of stay. The technicalcomplexity of the «Bikini» approach requires operations number more than 30 per year.

Custom Triflange Acetabular Components for Revision Hip Arthroplasty in the Patients with Severe Acetabular Defects: Planning, Surgical Technique, Outcomes

Employment of custom triflange acetabular components (CTAC) is one of the few options for pelvic reconstruction in the patients requiring complex acetabulum revisions with Paprosky 2 C, 3 A and 3 B defects and pelvic ring disruption.The purpose of the study was to describe the features of planning, surgical technique, and short-term treatment outcomes of the patients with significant acetabular defects, in which the revision hip arthroplasty was performed using the CTAC.Materials and Methods. A single-center analysis of a series of consecutive patients was performed: 50 complex acetabulum revisions in 47 patients (16 men and 31 women). The average age of the patients was 60±12 years (from 31 to 82; Me 62 years), the average body mass index was 29.7±6.3 kg/m2 (18.4 to 46.3; Me 29.0 kg/m).Results. The mean follow-up was 22±13 months (from 3 to 3.6 years; Me 20 months). The average Harris score increased from 27±7 (from 15 to 39; Me 27) before surgery to 64±16 (from 22 to 90; Me 67) a year after (p0.001). The level of pain according to VAS before surgery was 7±1 points (from 5 to 9; Me 7), after treatment it decreased to 2±1 points (from 0 to 7; Me 1, p0.001). In 17 cases out of 50 (34%), there was at least one complication: dislocations — 7 (14%) cases; infection — 3 (6%); loosening — 2 (4%); complications associated with the femoral component — 4 (8%), including 3 intraoperative fractures and 1 postoperative, associated with loosening of the implant; pronounced disturbances of static and locomotor functions — 2 (4%). 12 cases out of 50 (24%) required another surgery, all of which were performed in a year. The Kaplan-Meyer survival rate for the hip implants was 0.71, for the CTAC — 0.87.Conclusion. Employment of the CTAC for revision hip arthroplasty in the patients with significant acetabulum defects and pelvic ring disruption allows reliable fixation of the endoprosthesis components. The STAC placement technique is more anatomical than use of structural allografts, several augments or sup-cage systems. It allows reconstruction of extensive bone defects, theoretically avoiding the long-term problems with allografts, modular trabecular components, antiprotrusion systems and cup-cage. Although, to prove this, the longer follow-up is needed.

Long-term treatment results of congenital hip disease in adolescents

Backgrоund. An analysis of modern literature reveals that presently, there are no algorithms for determining the correct method of surgical treatment for adolescents with high congenital hip dislocation; few publications are devoted to the treatment of adolescents with this pathology. Children are treated by podiatrists until the age of 18 before transferring to adult specialists. There remain debatable issues of total hip replacement in adolescents because there are time limits for hip preservation. The search for improved treatment methods for adolescents with this pathology by preserving their own bone structures continues to be relevant.&#x0D; Aim. To evaluate the long-term results of the treatment of adolescents with complete congenital hip dislocation after intertrochanteric osteotomy using the authors technique.&#x0D; Materials and methods. From 19902006, in the Republican Orthopedic and Traumatological Center of the Republic of Dagestan and the clinic of the Department of Traumatology and Orthopedics of the Dagestan State Medical University, 37 patients with high congenital dislocation of the hip underwent 49 operations using the method developed by the authors. The surgeries were performed by a single orthopedist and were presented as an angulatory lengthening by transtrochantiс osteotomy of the femur by fixation with a fingered plate. All patients underwent clinical, radiographical, biomechanical, and statistical evaluation before and after surgery using the Harris and VAS scales. The results of the study were processed using the Student, Pearson, and Kolmogorov coefficients and confidence intervals.&#x0D; Results. Over a long-term treatment period of up to 10 years, the average Harris score increased from 44.2 (95% CI 38.747.9) to 80.5 (95% CI 77.185.3). After the 10-year follow-up period (1015 years after surgery), the scores gradually dropped to 72.4 (95% CI 70.178.3). Unsatisfactory treatment results were found in 13.5% of cases and were mainly associated with an unsuccessful choice of support point under the pelvis and the preservation of uncompensated shortening of the limb. The alignment of the created degree of angulation of the hip in terms of adolescent age groups was not established. Differences in treatment results (depending on the inter-operation time for the bilateral dislocation of the hip) were not established. At follow-up periods of 1015 years after surgery, total hip replacement was performed in 21 joints (56.7%).&#x0D; Conclusions. The proposed method of surgical treatment of congenital hip dislocation in adolescents improves the staticdynamic capabilities of the hip joint and remains effective over the following 15 years of life. The duration of inpatient treatment is reduced and does not interfere with subsequent total hip arthroplasty.

Today, the main method of surgical treatment of dysplastic coxarthrosis among adults is total hip prosthetics. Distant positive results according to foreign authors are 76–89%. One method of rehabilitation is physiotherapeutic treatment. The absence of standardized physiotherapeutic treatment protocols leads to a sharp reduction in the prescription of this type of rehabilitation measures. The aim of the study is to assess the long-term results of hip joint endoprosthetics among patients with dysplastic coxarthrosis using the developed physiotherapeutic treatment technique. Research materials and methods. For the period from 2010 to 2014, 205 patients were performed an operation with dysplastic coxarthrosis 1, 2, 3 degrees of Crowe. In the pre- and postoperative periods, patients of the main group were prescribed physiotherapeutic treatment according to the developed methodology. Evaluation of the results was carried out 12 months after surgical treatment using clinical and radiological methods, questionnaires using the Harris scale, SF-36. The obtained data were processed using statistical methods: Student coefficient, Pearson coefficient, correlation method. Results. When analyzing distant results, the average Harris score in the main group 85.82 (84.93–86.71) was significantly higher than in the comparison group 83.01 (82.02–84.00). The average score of the SF-36 questionnaire in the main group was significantly higher than in the comparison group (p &lt; 0.001). Mental health indicators of patients were not significantly different from those of the postoperative period and were at a high level. Conclusions. Prescription of physiotherapeutic treatment promotes rapid healing of postoperative wounds and improves results of surgical treatment.

Total hip arthroplasty for intertrochanteric fracture fixation failure

BackgroundIntertrochanteric fracture is a common fracture suffered by elderly patients. Total hip arthroplasty (THA) is regarded as a salvage operation to restore hip joint function after fixation failure, which remains somewhat controversial due to some clinical potential issues.Methods18 elderly patients (average age 70.3 years) each with intertrochanteric fracture fixation failure treated with THA between September 2013 and October 2016 were retrospectively analyzed. Internal fixation treatments involved 5 patients who had received proximal femoral nail anti-rotation, 7 who received locking proximal femur plates and 6 who received dynamic hip screws. All patients were treated with THA using biological acetabular prosthesis and hip arthroplasty (HA) coating skillet femoral prosthesis, with the greater trochanter fixed using wire or steel when necessary. Patients’ Harris scores pre- and post-treatment, SF-36 Health Questionnaire score and digital radiology (DR) were used for joint prostheses initial stability and survival evaluation.Results15 patients completed follow-up periods ranging between 19 and 54 months (mean 26.2 months; 1 patient died from a pulmonary embolism, 1 patient died from pulmonary heart disease 1 year after surgery and 1 patient withdrew for personal reasons). There were no joint infections, periprosthetic fractures or dislocations. The average Harris score increased significantly, from 32.68 ± 12.04 points before surgery to 91.08 ± 5.9 points at 24 months post-treatment. SF-36 scores were significantly increased.ConclusionTHA as salvage treatment for failed internal fixation of intertrochanteric femoral fractures in elderly patients significantly reduced hip pain and restored joint function, and early clinical outcomes were satisfactory.

Free graft of vascularized iliac bone flap based on deep iliac circumflex vessels for the treatment of osteonecrosis of the femoral head

Objective To investigate the feasibility and clinical efficacy of free graft of vascularized iliac bone flap based on deep iliac circumflex vessels for the treatment of osteonecrosis of femoral head (ONFH). Methods Twelve cases of ONFH (13 hips) received free graft of vascularized iliac bone flap based on deep iliac circumflex vessels from April, 2016 to July, 2017. The average Harris score was (74.7±6.9) in the second stage and (68.6±9.2) in the third stage. After debriding the necrosis bone of the femoral head, the contralateral vascularized iliac bone flap had been harvested, and then implanted into the femoral head. The deep iliac circumflex artery and its accompanying vein were anastomosed with the transverse branch (or ascending branch) of the lateral circumflex femoral artery and concomitant vein respectively. The herringbone brace was used for hip fixation for 3 weeks after operation. X-ray examination(1, 3, 6, 9 and 12 months after operation, respectively) and Harris hip score (6 and 12 months after operation, respectively) were performed to evaluate the recovery results of the femoral head. Scores were recorded and analyzed by paired t-test. The difference was considered to statistically significant if P<0.05. Results The patients were followed-up for 15 (12-20) months. The iliac bone flap of 12 patients (13 hips) healed well. There was no necrosis and collapse in 12 hips, except 1 femoral head collapsed slightly because of weight loading too early. The average Harris score was (91.6±4.5) of the second stage and (84.8±6.1) of the third stage. Compared with scores before the operation, the difference was statistically significant (P<0.05). Conclusion Free vascularized iliac bone grafting based on deep iliac circumflex vessels is an ideal treatment for ONFH head in middle and advanced stage.

The effects of total hip arthroplasty in treating hip bony fusion in young and middle-aged patients with ankylosing spondylitis

BackgroundThis study aims to investigate the curative effects of total hip arthroplasty (THA) in treating hip bony fusion for young and middle-aged patients with ankylosing spondylitis (AS).MethodsThe clinical data of 26 young and middle-aged patients with AS (31 coxae), who were treated with THA and followed-up for more than 3 years in the period between February 1998 and May 2013, were retrospectively analyzed. Among these patients, 22 patients were male (25 coxae) and 4 patients were female (6 coxae). Patients’ age ranged within 19–50 years old, with an average of 31.5 years old. The intervals from arthroplasty to the occurrence of hip joint lesions caused by AS ranged within 2–26 years, with an average of 11.2 years. The average Harris score before the surgery was 19.0 ± 11.5 points.ResultsFemoral proximal cleavage fracture occurred in one coxa during the surgery and was fixed by the steel wire cerclage. Sciatic nerve traction injury occurred in one coxa after the surgery, which recovered after 6 months. Posterior hip dislocation occurred in one coxa and was immediately treated with manual reduction. All patients were followed-up, and follow-up duration ranged within 36–123 months, with an average of 46.5 months. In the last follow-up, the average Harris score was 87.1 ± 13.1 points, total passive range of motion was 215.0 ± 22.0°, and passive range of flexion was 90.8 ± 9.3°. All these indexes significantly increased compared with pretreatment (P < 0.01). A periacetabular radiolucent line occurred in one coxa with a width of < 2 mm, and no femoral radiolucent line was found during follow-ups in any patient. Heterotopic ossification occurred in four coxae.ConclusionTHA treatment for hip bony fusion caused by AS can achieve satisfactory hip function recovery and excellent prosthesis survival rate.

Proximal femur nail vs cemented bipolar prosthesis in unstable intertrochanteric femur fractures in elderly: A prospective study

Background: Surgical stabilization of Intertrochanteric fracture femur is one of the most commonly performed orthopaedic procedures. Present study was done to analyse the outcome of various treatment modalities for unstable Intertrochanteric fracture femur in elderly. Methods: The present clinical study was carried out at our tertiary care hospital. Study duration was from Jan 2015 to June 2016. 70 patients over the age of 60 years with unstable Intertrochanteric fracture were selected. Outcome of management of unstable Intertrochanteric fracture femur was analysed using Harris Hip Score in Proximal femoral nail (PFN) and Cemented Bipolar prosthesis (CBP). Results: Most of the patients were between 60-70 years of age. The average age of study group was 68.9 years. 35 patients treated with PFN and 35 patients treated with CBP. Superficial infection was seen in 4 patients and was the most common complication found in cemented bipolar prosthesis. External rotation deformity was second most common complication seen in 5 patients. Out of them, 2 patients were of CBP and 3 patients of PFN. Deep wound infection occurred in 1 case of CBP. Average blood loss in patients operated with PFN and CBP were 205 ml and 311ml in CBP. It was noted that shorter time was required for P.F.N (55 min) and then for CBP (84min). Average Harris score for PFN and CBP at 3 months, at 1 year and at 2 years were 70.1:74.9, 86.4:78.2 and 84.4:76.6. Conclusion: Considering the amount of blood loss, duration of the surgery and Harris Hip Score, PFN is better for unstable inter trochanteric fracture femur than CBP. The only advantage of Hemiarthroplasty was early weight bearing. But at the end of 1 year and 2 years, the outcome of PFN was better than Cemented Bipolar prostheses. Statistical method: Data were reported as mean, median (range) or number. t-test was used to assess significant difference among all numerical parameters of the study within the two surgical groups. P–values < 0.05 were considered statistically significant.

Justification of a new method of alternative treatment of high congenital hip dislocations in adolescents and adults

Aim. Justofocation of a new method of hip joint stabilization in adolescents and adults with congenital hip dislocation by preserving its own bone structures. Methods. The biomechanical substantiation of a new method of surgical correction of the proximal femur is presented. A primary analysis of the surgical treatment of congenital hip dislocation was performed on 101 patients (116 joints) aged 14 to 30 years (average age 21.3 ± 3.5 years) by creating an additional point of support for the pelvis according to the authors' method with 10 to 15-year follow up. The technique includes angulating elongating squamous oblique osteotomy of the thigh, which allows extending the limb simultaneously to 4 cm and restoring its biomechanical axis. All patients were evaluated clinically, radiologically and using Harris scale before and after the surgery. Results. At the analysis of the treatment results 10-15 years after the operation in 56 patients, the average Harris score increased from 42.7 (from 40.1 to 45.3) to 81.1 (77.2-86.7). Valgus proximal hip and oblique intertrochanteric osteotomy allowed elongating the limb in one-side hip dislocation by 3.2 ± 0.8 (95 % CI 2.8-4.0 cm), shortening of the limb by 3 cm persisted in all patients with one-side hip dislocation. In 37 patients (43 joints) podographic examination revealed restoration of rhythmic walking and longer single-support time. Conclusion. The suggested method of treatment of high congenital hip dislocation is an effective and minimally invasive method of stabilization of the hip joint in adolescents and adults. We discuss the question of possible reconstructive surgeries with preserved own bone structures in young patients aged 14 to 30 years, creating of bone mass in hip joint area for further joint replacement.

Clinical application of uncemented distal stem fixation for revising femoral prosthesis of hip arthroplasty in elderly patients

Objective To evaluate the effectiveness of uncemented distal stem fixation for elderly patients needing revision of femoral prosthesis of hip arthroplasty. Methods From July 2005 to January 2013, 22 patients(12 males and 10 females)aged from 70 to 85 years(average: 76 years old)with aseptic loosening of the femoral stem undergone revision via uncemented distal stem fixation were enrolled into this study.Of all patients, 10 had revision on the right side and 12 on the left side; 11 patients received artificial replacement of the femoral head; 9 had total hip replacements; 2 had femoral fractures.According to the Paprosky classification system, 2 cases were type I, 12 were type Ⅱ, 6 were type ⅢA, and 2 were type ⅢB.Femoral stems for revision included MP(Link)and Solution(Depuy). The Harris score, clinical and radiological results were retrospectively analyzed. Results All patients were followed up for 48 to 78 months(mean: 61 months). The average Harris score increased from 38(25-46)to 87(76-94). All prostheses were initially stable, and no infection, dislocation or complication like deep venous thrombosis was observed after revision.All patients were able to walk without assistance; two of them had minor claudication; radiographs after surgery showed well-positioned implants with increased bone density and thickness around the prosthesis and without loosening or subsidence. Conclusions Reliable axial and anti-rotational stability can be achieved by using uncemented distal stem fixation, with good short-and medium-term clinical results for revision in elderly patients with less severe bone defects than those in Paprosky Ⅳ.
