Evaluation of the Tensor Fascia Lata Muscle Pedicle Bone Grafting Technique in the Management of Avascular Necrosis of the Femoral Head: An Observational Clinical Study.

Osteonecrosis of the hip is defined as necrosis of the bone tissue due to some form of vascular insult, subsequently leading to the collapse of the femoral head and secondary osteoarthritis, which leads to pain and impaired joint function. This disease is widely known to affect middle-aged groups; however, in the Indian population, even younger people are more commonly affected. The disease has a debilitating effect on the activities of daily living (ADL) and the productivity of individuals and has financial consequences. With the increased utilization of magnetic resonance imaging (MRI) in society, the disease is diagnosed in its early stages. Hip-preserving surgery like tensor fascia lata (TFL) muscle pedicle iliac bone grafting should be given a chance to preserve the native femoral head. At a tertiary care teaching hospital in Gorakhpur, India, an observational clinical study was carried out. This study comprised 40 patients, ages 18-50 years, with femoral head osteonecrosis (stages II and III of the Ficat-Arlet staging system), who came to our institute's orthopedic outpatient department. Patients were treated with multiple drillings, curettage, and cheilectomy of the femoral head, in addition to TFL muscle pedicle bone grafting. The Harris hip score (HHS) was utilized to assess the clinical results, and the radiological assessment focused on signs of revascularization. In our study, the most prevalent age group was 20-30 years (67.5%), with a male predominance (85%). Among our cohort of 40 patients, the HHS indicated excellent outcomes (90-100) in 14 cases (35%), good outcomes (80-89) in 19 cases (47.5%), fair outcomes (70-79) in six cases (15%), and poor outcomes (<70) in one case (2.5%), at the time of the final follow-up. The final follow-up period varied from one to 10 years. TFL muscle pedicle bone grafting procedure provides excellent clinical and radiological outcomes, especially in young patients in whom femoral head-preserving surgery is preferred over total hip arthroplasty. This procedure is effective in both early and advanced stages of femoral head osteonecrosis, provided there are no arthritic changes. It reduces symptoms and improves functional outcomes.

Meyer's procedure for grade I and II AVN in delayed femoral neck fractures: A retrospective study

BackgroundFemoral neck fractures are challenging injuries that can lead to non-union and avascular necrosis (AVN), particularly in cases of delayed presentation. Muscle pedicle bone grafting has been suggested as a potential approach to supplement blood supply to the fracture site. The objective of this study was to evaluate the efficacy of Meyer's procedure in the treatment of ununited femoral neck fractures with grade I and II AVN, which involves internal fixation and quadratus femoris-based muscle pedicle bone grafting. MethodsFive patients with delayed presentation of femoral neck fractures with grade I and II AVN were included in this retrospective study. The surgical approach for all patients was Meyer's procedure, consisting of open reduction and internal fixation followed by a muscle pedicle graft and cancellous bone graft. Fixation was done with parallel cannulated screws or non-cannulated cancellous screws. In all cases, the quadratus femoris muscle pedicle graft was utilized. The average follow-up duration was three years. ResultsAll five patients achieved radiological union and reported excellent functional outcomes, including the ability to perform activities such as squatting and sitting cross-legged. According to the Salvatti and Wilson hip rating system, three cases had excellent results, one had good results, and one had fair results. Two cases had coxa vara, and one case had temporary loss of scrotal sensation as complications. Avascular necrosis and transient foot drop were not observed in any cases. Using the modified Harris hip score, all cases achieved good or excellent outcomes, with an average follow-up period of 130 weeks and radiological union occurring at an average of 6.5 months. ConclusionMeyer's procedure provides stable internal fixation and enhanced blood supply to promote union in ununited femoral neck fractures with grade I and II AVN. This technique can achieve good or excellent functional outcomes and may represent a viable treatment option for patients with these types of fractures. However, further research is needed to confirm these findings and optimize treatment strategies.

A modified surgical method for the treatment of ONFH: quadratus femoris muscle pedicle bone grafting with preservation of the posterior superior retinacular artery

BackgroundOsteonecrosis of the femoral head (ONFH) can lead to pain and loss of function of the hip joint, which places a great burden on patients and society. Surgery is the main treatment for osteonecrosis of the femoral head, and quadratus femoris muscle pedicle bone grafting has a definite therapeutic effect as one method of surgery for the treatment of ONFH. However, the posterior superior retinacular artery is often injured during quadratus femoris muscle pedicle bone graft surgery. There is evidence that this artery is extremely important to the femoral head, as injury to this artery will seriously affect the blood supply of the femoral head. Therefore, this situation restricts the clinical application of quadratus femoris muscle pedicle bone grafts. We aimed to explore a new surgical method of quadratus femoris muscle pedicle bone grafting that can preserve the integrity of the posterior superior retinacular artery.MethodsWe modified the traditional quadratus femoris muscle pedicle bone graft and preserved the integrity of the posterior superior retinacular artery. To explore the safety and feasibility of the operation, we simulated the operation on 6 fresh frozen cadavers (12 hips) and measured the related data. We also tried this modified surgical method in the clinic and collected detailed data from the patients.ResultsBy simulating the modified quadratus femoris muscle pedicle bone graft on the hip joints of fresh frozen cadavers, we found that the posterior superior retinacular artery existed in all cadaver specimens and that the sources may be different (MFCA or IGA). In the modified operation, the joint capsule did not need to be cut during the operation; therefore, the integrity of the posterior superior retinacular artery was preserved. The quadratus femoris muscle was exposed via the posterior approach of the hip joint, and then the quadratus femoris muscle pedicle bone flap was chiseled. After the pedicle of the quadratus femoris muscle was loosened properly, the migration distance of the quadratus femoris muscle pedicle bone flap reached 5.89 ± 0.45 (χ ± s) cm. The bone flap was trimmed properly and placed on one side. Next, we drilled a bone tunnel from the external intertrochanteric aspect of the capsule of the hip joint, and the bone tunnel broke through the sclerosing zone and proceeded straight to the necrotic area of the femoral head. Next, the necrotic bone was removed with a ring saw and arc bone knife, autogenous bone or allogeneic bone was filled into the bone groove according to the situation, and the cancellous bone in the bone groove was tamped by percussion. Then, the bone flap was inserted into the bone groove, and appropriate pressurization was performed. The depth of the bone groove was determined by the location of ONFH. We found that the furthest distance between the bone groove and the femoral head was 4.76 ± 0.07 (χ ± s) cm and that the length of the bone flap was (4.91 ± 0.23) (χ ± s) cm. This means that when the depth of the bone groove reached the area of ONFH, the quadratus femoris muscle pedicle bone flap had a sufficient length and migration distance to be embedded in the area of ONFH and firmly fixed, and the quadratus femoris did not have much tension. The closest distance between the posterior superior retinacular artery and the bone groove was (1.11 ± 0.96) (χ ± s) cm. When the bone groove was created in this area, the edge of the bone groove had a safe distance of at least 1 cm from the posterior superior retinacular artery of the femoral head. We attempted to implement this modified operation clinically. During the procedure, the quadratus femoris muscle pedicle bone flap was embedded into the drilled bone groove and fixed with a magnesium nail. There was no sliding of the bone flap after the operation, and the posterior superior retinacular artery was intact. We followed the patient for 3 months and found that the patient recovered well with no weight-bearing by the affected limb. The duration of the modified operation was shorter than that of the traditional quadratus femoris muscle pedicle bone graft, the amount of bleeding was significantly reduced, the postoperative pain was lessened, and no special discomfort was reported. Postoperative imaging examination showed that the collapse of the femoral head had been partially corrected and that the bone flap had gradually fused with the surrounding bone.ConclusionsThrough this experimental study, we confirmed the feasibility of the modified method for quadratus femoris muscle pedicle bone grafting with preservation of the posterior superior retinacular artery. This modified operation not only retains the integrity of the posterior superior retinacular artery of the femoral head but also reduces the difficulty of the operation and shortens the surgical time, which is of great clinical significance.

Comparative Study Between Closed Reduction Internal Fixation Alone Versus Closed Reduction Internal Fixation and Addition of Muscle Pedicle Bone Graft for Prevention of Osteonecrosis in Cases of Displaced Femoral Neck Fractures.

In patients of less than 60years of age, osteosynthesis is the treatment of choice for displaced femoral neck fractures (Garden 3 and 4). Most of these fractures unite well but chances of osteonecrosis are quite high even after early operations and till date there is no well-defined method of prediction and prevention of osteonecrosis. Vascularized bone graft may prevent the development of osteonecrosis. This is a retrospective case control study done in an urban Medical College in eastern India and tried to evaluate efficacy of addition of quadratus femoris muscle pedicle bone graft in cases of osteosynthesis comparing the results of cases treated with closed reduction and internal fixation alone for femoral neck fractures We have taken into consideration 45 consecutive cases from each group with identical demographic background and of very similar age pattern of 20years to 60years.For further reference, we will describe Group I for closed reduction and CHS/DHS only, and Group II for closed reduction CHS and quadratus femoris muscle pedicle graft. Satisfactory bony union occurred in 42 out of 45 follow-up patients in Group 1 (93.3%) and 43 out of 45 patients in Group 2. (95.5%) In 2- to 10-year follow-up period, eight patients (18.6%) developed osteonecrosis in Group I, and in Group 2, in the same period, there were no cases of osteonecrosis. Addition of quadratus femoris muscle pedicle bone graft is a very effective procedure for prevention of osteonecrosis when we attempt osteosynthesis by closed reduction and internal fixation for displaced femoral neck fractures.

Comparative Study Between Core Decompression in Low Grade AVN Of Femoral Head and Core Decompression with Intraosseous Ibandronate at a Teaching Hospital

Background: Many options for treatment of avascular necrosis have been described, including core decompression, vascularised and non-vascularised bone grafting, muscle pedicle bone grafting, bisphosphonates and various osteotomies. In present study we compared core decompression alone with core decompression &amp; intraosseous ibandronate in low grade AVN of femoral head at a teaching hospital. Material and Methods: Present study was a prospective, interventional study conducted in patients with low grade AVN of Femoral head, Ficat Stage I or II, fit for surgery, willing to participate. Preoperatively patients were randomly divided into two groups as core decompression alone &amp; core decompression with intraosseous ibandronate. Results: During study period total 30 patients underwent surgery; patients were randomly divided into two groups as core decompression (n=15) &amp; core decompression with intraosseous ibandronate (n=15). General characteristics such as age, gender, side, co-morbidities, Ficat Staging &amp; Pre-Operative Harris Hip Score were comparable in both groups &amp; difference was not significant statistically. Post-Operative Harris Hip Score was more than 60 in 9 (60%) patients from core decompression with intraosseous ibandronate group as compared to 6 (40%) patients from core decompression group &amp; difference was significant statistically. Minor complications were observed in both groups, managed conservatively. None of study patients required THA during study period. Conclusion: Better results were noted in core decompression with intraosseous ibandronate group as compared to core decompression group.

Muscle pedicle bone graft in ununited fracture neck of femur in children

Delayed presentation of fracture neck of femur is not uncommon in our scenario and is difficult to treat because of precarious vascularity and bony defect at fracture site. The purpose of the present study is the analysis of functional outcome of the muscle pedicle bone graft porcedure in ununited fracture neck of femur in children and adolescents.: Sixteen patients with ununited fracture neck of femur (presenting late) in children and adolescents were treated with quadratus femoris based muscle pedicle bone graft along with open reduction and internal fixation. Mean age of the patient was 14.25 year (range 12-16 years). Boys dominated our series (n= 10 i.e.62.50%). Road traffic accident was the leading cause. Average injury –surgery interval was 5.88 week (range 3-9 week). A minimum follow up was two years. There were 2 Transepiphyseal, 11 Transcervical and 3 Cervicotrochanteric fractures. Most of the cases showed union in 16 to 24 weeks. In one case there was implant failure. : The result was analysed using Harris Hip Score. We had 11 (68.75%) excellent, 2 (12.50%) Good, 2(12.50%) Fair and one (06.25%) Poor results in our series.Quadratus femoris based Muscle pedicle bone with internal fixation is a very effective method to address the difficult problem of non-union fracture neck of femur. There was statistically significant association (p value &amp;#60;.005) between accuracy of reduction and functional outcome.

A prospective study of radiological and functional outcome of non union scaphoid fractures treated by pronator quadratus muscle pedicle bone graft

Scaphoid fractures are common, but present unique challenges because of the particular geometry of the fractures and the tenuous vascular pattern of the scaphoid. Delays in diagnosis and inadequate treatment for acute scaphoid fractures can lead to nonunions and subsequent degenerative wrist arthritis. Scaphoid nonunions can present with or without avascular necrosis of the proximal pole, and may show a humpback deformity on the radiograph. If left untreated, scaphoid nonunions can progress to carpal collapse and degenerative arthritis. Surgical treatment is directed at correcting the deformity with open reduction and internal fixation with bone grafting. Recently, vascularized bone grafts have gained popularity in the treatment of scaphoid nonunions, particularly in cases with avascular necrosis. This study gives us a radiological and functional outcome of 10 cases operated by pronator quadratus based muscle pedicle bone graft for scaphoid non unions at waist level.

Rectus Femoris-based Muscle Pedicle Bone Graft for Osteonecrosis of Femoral Head: A New Surgical Technique

The pre-collapse and pre-degenerative stages of osteonecrosis of femoral head in young adults are preferably treated by a femoral head preservation operation with the objective to delay or possibly avert the further necrosis, collapse and degeneration of the hip joint. To salvage the early stages of the disease, several muscle pedicle bone grafting (MPBG) procedures based on Quadratus Femoris, Tensor Fasciae Latae, and Sartorius muscles have been described in the literature. To overcome the limitations of these procedures, the authors describe here a much simpler and safer MPBG based on the straight head of the Rectus Femoris with distal transposition of its origin along with anterior inferior iliac spineto the head-neck junction. To the best of our knowledge, MPBG based on Rectus Femoris has not been reported in the currently available literature on osteonecrosis of femoral head. Surgical technique with emphasis on protection of the posterior retinacular vessels, post-operative care and expected outcome is presented.

Comparison of Management of AVN of Femoral Head by Decompression with TFL Muscle Pedicle Bone Graft and Fibular Graft

Background: Avascular necrosis (AVN) of the femoral head usually occurs in the active age of life, and is an increasingly common cause of musculoskeletal disability. Objective: we envisage to evaluate and compare the clinic oradiological outcomes between TFL muscle pedicle bone graft and no vascularized fibular grafting after core decompression prior to hip joint involvement of AVN femoral head provides painless and mobile life. Method: January 2013 to December 2019, total 64 hips (44 patients) in the age group of 18–48 years (mean 30.36±4.64 years) were included in this prospective study. Ficat and Arlet staging system was used, Stage I (n=10 hips), Stage II (n=44 hips) and stage III (n=10) of AVN of femoral head, were included after clinical and radiological evaluation, where 32 hips (half of all stage-I, II and III) were treated with fibular graft (Group 1) and rest 32 hips were treated with TFL muscle pedicle bone graft (Group 2) after decompression of femoral head. Preoperative Harris Hip Score (HHS), visual analog score (VAS), plain radiographs, and magnetic resonance imaging (MRI) were compared with serial postoperative HHS, VAS, plain radiographs at regular interval. The average follow up was 56 months. Result: Out of 44 patients, male was 28 (63.64%) and female was 16 (36.36%). Failure of surgery was defined as progression of the disease, which was n=1,10% (1/5, 20% in group 1, 0% in group-2) in stage I, n=12/44, 27.27% (7/22, 31.82% in group-1 and 5/22, 22.73% in group-2) in stage II and n=5/10, 50% (2/5, 40% in group 1 and 3/5, 60% in group 2) in stage III disease. Median values of HHS at the end of the follow up in Group I was 80 and 76 in Group 2, compared to the preoperative HHS of 56 and 52 respectively. Overall satisfactory result was 71.88%, p value was <0.01, that is significant. In group 1 satisfactory result was 22/32 (68.75%) but 24/32 (75%) in group 2, no statistical significant difference (>0.05) between two groups. Even in early stage III disease, only 50% was effective. Conclusion: Core decompression with bone graft is effective in preserving the sphericity of the femoral head and to delay the progression in the early stages of the AVN of femoral head, (Stage I and II), fibular graft gives early stability but long term results are similar in both group.

PRONATOR QUADRATUS MUSCLE PEDICLED BONE GRAFT FOR DELAYED UNION SCAPHOID

Background: The human scaphoid bone is one of the carpal bones of the wrist. Its fracture is the most common type of carpal bone fracture. Scaphoid nonunion is a well-known and common problem. Both clinical and biological factors contribute to the development of nonunion. Several techniques of bone grafting have been used in the management of scaphoid fracture nonunion. The union rate achieved with standard nonvascularized bone grafts was poor, especially in case of avascular necrosis and pseudarthroses, whereas the use of vascularized bone grafts results in better union rates. Pronator quadratus pedicled bone graft is described as one of the successful techniques that treat delayed union of the scaphoid fracture. Objective: To evaluate the outcomes and results of pronator quadratus muscle pedicle bone graft for patients who were suffering from delayed union or nonunion of scaphoid bone fracture. Patients and Methods: Ten patients suffering from delayed and non-united scaphoid fractures, seven males and three females, aging from 17 to 54 years old. We used the pronator quadratus muscle pedicled bone graft to treat all these patients. Results: Complete union was achieved in seven patients, 6 patients of them were suffering from waist non united scaphoid fracture, and one patient of four patients suffering from non-united proximal pole scaphoid fracture. Conclusion: The use of the pronator quadratus pedicled bone graft in delayed union of the scaphoid waist fractures achieved a high rate of union with excellent and good functional outcomes. A poor result occurred on using the pronator quadratus pedicled bone graft in delayed union of the scaphoid proximal pole fracture.

Results of quadratus femoris muscle pedicle bone grafting (Meyers' procedure) in the management of ununited femoral neck fractures.

Femoral neck fractures in young patients are associated with increase complication risk. The objective of this study was to evaluate the results of quadratus femoris muscle pedicle grafting in the treatment of ununited femoral neck fractures. This study includes 16 patients with ununited femoral neck fractures treated with quadratus femoris muscle pedicle graft. 7 patients had neglected femoral neck fractures while 9 had ununited femoral neck fractures after fixation. Quadratus femoris muscle with 2 × 1 × 1 cm (length-width-height) bone in its insertion was elevated and placed in the posterior cortex of the femoral neck with additional cancellous graft from the posterior iliac bone. The graft was fixed with 3.5-mm cortical screws. The average follow-up period was 96 weeks and the radiological union occurred at an average of 7 months. The femoral inclination of all patients was 128.5° ± 3.9° with an average 7 (range 0-35) mm thigh atrophy in the last follow-up visit. Only 1 patient (6%) had avascular necrosis of the femoral head and was treated with hip arthroplasty. Quadratus femoris muscle pedicle grafting provides better stability and blood supply in ununited femoral neck fractures. Achieving fracture union provides better clinical and functional results in the treatment of femoral neck fractures.

A cross sectional study of outcomes of muscle pedicle grafting in neck of femur fractures and avascular necrosis of femoral head

Avascular necrosis (AVN) of the femoral head is a progressive disease that generally affects patients in the second through fifth decades of life; if left untreated, it leads to complete deterioration of the hip joint. Treatments range from simple decompression of the femoral head, to muscle pedicle bone grafting of the involved area, or by using a vascularized fibular graft with varying degree of success. If the disease have progresses further causing secondary arthritis, Total Hip Arthroplasty may be necessary.We present a study of management of 60 young patients aged less than 50 years having either early stage AVN (stage I and II A/B of Ficat & Arlet classification) or Neck of the femur fractures, treated with quadratus femoris muscle pedicle bone grafting & cancellous screws. With aim To evaluate the results of the above modality in the management of AVN of the hip & neck femur fractures and to study the radiological & functional outcome of the procedure in young patients.

Neglected femoral neck fractures in cerebral palsy: a narrative review.

Hip fractures are severe conditions with a high morbidity and mortality, especially when the diagnosis is delayed, and if formulated over 30 days after the injury, is termed a ‘neglected femoral neck fracture’ (NFNF).Cerebral palsy (CP) is probably one of the major risk factors for NFNF in Western countries, mainly because of both cognitive and motor impairments. However, considering the high prevalence of fractures in these patients, the incidence of NFNF in this population is probably underestimated, and this condition might result in persistent hip or abdominal pain.Several techniques are available for the treatment of NFNF (i.e. muscle pedicle bone graft, fixation with fibular graft, valgisation osteotomy), but most of them could affect motor function.Motor function must be preserved for as long as possible, in order to enhance the quality of life of CP patients.After discussing published NFNF cases in CP patients and available treatment options, a practical approach is proposed to facilitate the orthopaedic surgeon to both early identify and appropriately manage these challenging fractures.Cite this article: EFORT Open Rev 2020;5:58-64.

Outcomes of Core Decompression with or without Nonvascularized Fibular Grafting in Avascular Necrosis of Femoral Head: Short Term Followup study.

Background:Avascular necrosis (AVN) of the femoral head usually occurs in the third to fifth decade. The treatment options depend on the stage of disease varying from nonoperative treatment to surgical procedure including core decompression (CD) with or without nonvascularized or vascularized fibular graft, muscle pedicle bone grafting, osteotomies, and arthroplasty. Finite life of the total hip arthroplasty (THA) prosthesis limits its use in young adults or in middle aged. In this study, we envisage to evaluate the clinicoradiological outcomes of CD and nonvascularized fibular grafting in early stages of AVN femoral head.Materials and Methods:Our study is longitudinal observational study including 76 hips (46 patients) in the age group of 18–48 years (mean 30.07 years). Ficat and Arlet staging system was used and only early stages, that is, Stage 1 (n = 36 hips) and Stage 2 (n = 40 hips) were included in the study. The cases with traumatic AVN were excluded. All patients in Stage 1 underwent CD (Group 1) and those in Stage 2 underwent CD and fibular grafting (Group 2). Preoperative Harris Hip Score (HHS), visual analog score (VAS), plain radiographs, and magnetic resonance imaging (MRI) were compared with serial postoperative HHS, VAS, plain radiographs, and MRI taken at different intervals.Results:Average period of followup was 53.5 months (44–63 months). Radiological progression was not seen in 55 hips out of 76 hips (72.3%), whereas 21 hips (27.6%) demonstrated signs of progression and collapse. Failure of surgery was defined as progression of the disease, which was 25% (n = 9) in Group 1and 30% (n = 12) Group 2. Median values of HHS at the end of the followup in Group 1 was 77 and in Group 2 was 71.5 compared to the preoperative HHS of 48 and 62 in Group 1 and 2, respectively. Median values of VAS at the end of the followup in Stage 1 was 0 and in Stage 2 was 2 compared to the preoperative VAS of 6 and 8 in Group 1 and Group 2, respectively.Conclusion:CD with or without fibular grafting is effective in preserving the sphericity of the femoral head and to delay the progression of the AVN of femoral head in the early stages, that is, Stage 1 and Stage 2 and aids in the early revascularization of ischemic femoral head and is a useful modality to negate or delay the requirement of THA.

Muscle pedicle bone grafting using the anterior one-third of the gluteus medius attached to the greater trochanter for treatment of Association Research Circulation Osseousstage II osteonecrosis of the femoral head.

The aim of this study was to evaluate the effectiveness of our technique on further collapse of the femoral head in Association Research Circulation Osseous (ARCO) stage II, patient's functional improvements, and analyze the survival rate of the affected hip. Between June 2007 and March 2015, 24 hips diagnosed with osteonecrosis of the femoral head (ONFH) were treated with our muscle pedicle bone grafting (MPBG) technique using anterior one-third of gluteus medius attached to the greater trochanter. The group was consisted of 15 men and eight women, mean age of 36years at the time of surgery. Mean follow-up was 6.2years. Four hips showed regeneration, 11 hips showed no progression, and nine hips showed slight extent of the lesion. But during the follow-up, three hips underwent total hip arthroplasty at the mean follow-up of 5.8years after the surgery. The survival rate at the last follow-up was approximately 87.5%. Excluding the three failed cases, the mean total Harris hip score was improved from 57.2 to 82.3 points (p < 0.05). We had no case of complications such as limping, numbness, wound infection, heterotopic ossification, nor intra- and post-operative fracture. We showed 87.5% of survival rate by average of 6.2-year follow-up, maximum of 10.1years. And compared to other reports, our technique showed relatively good results. In the short term, our modified MPBG technique seems to be effective in ARCO stage II ONFH. We, therefore, suggest this technique as one of the promising treatments of choices for patients with ARCO stage II ONFH.

Anconeus Muscle-Pedicle Bone Graft With Periosteal Coverage for Osteochondritis Dissecans of the Humeral Capitellum.

Background:Treatment of advanced osteochondritis dissecans (OCD) of the capitellum is controversial, especially in moderate-sized lesions.Purpose:To establish a treatment algorithm for capitellum OCD, we tried to determine the utility of and problems associated with anconeus muscle-pedicle bone graft with periosteal coverage (ABGP) for the treatment of moderate-sized articular OCD defects of the capitellum.Study Design:Case series; Level of evidence, 4.Methods:According to our protocol for elbow OCD, 16 patients (15 males, 1 female; age range, 12-17 years; mean age, 14.4 years) with a moderate-sized OCD lesion of the humeral capitellum were treated with ABGP. All patients had a full-thickness, unstable OCD lesion that was 10 to 15 mm in diameter. Clinical results and postoperative images, including radiographs and magnetic resonance imaging (MRI), were evaluated at a mean follow-up of 31 months (range, 24-66 months).Results:All but 1 patient had functional improvement after the procedure and returned to previous sporting activities within 6 months. One female patient needed 1 year for functional recovery due to development of postoperative chronic regional pain syndrome (CRPS). Two patients required additional surgery, including shaving of the protruding cartilage, and they returned to their previous level of activity. Mean arc of range of flexion-extension motion was 117° preoperatively and 129° at follow-up (P = .031). Mean elbow function as assessed with the clinical rating system of Timmerman and Andrews was 136 preoperatively and 186 at follow-up (P = .00012). Bony union of the graft as demonstrated by trabecular bone bridging on radiography was obtained within 3 months in all patients. Postoperative MRI was examined for 14 patients at 6 to 12 months after the procedure; the MRIs showed near-normal articular surface integrity in 9 of the 14 patients (64%) and underlying bony structure in 10 of the 14 patients (71%).Conclusion:Improvement after ABGP was obtained within 6 months in all except 1 patient, who developed CRPS. Postoperative radiography and MRI revealed near-normal articular surface integrity or underlying bony structure. This procedure is useful as a surgical option for a moderate-sized articular OCD lesion in the elbow.

Anterior greater trochanteric muscle pedicle bone grafting: a viable graft option adjunct to hip osteotomy or fracture surgery.

The objectives were to evaluate a technique, outcome and complications following anterior greater trochanteric with gluteus medius muscle pedicle bone graft (AMG) procedure in the treatment of adolescent and active adult hip disorders. 20 patients (20 hips) with a mean age of 22.7 ± 15.6 (range 10.0-63.5) years who had undergone AMG and been followed up more than 12 months postoperative were retrospectively enrolled in our study. The AMG procedure was performed in conjunction with subcapital osteotomy for slipped capital femoral epiphysis in 12 and open reduction for fracture/dislocation in 8 hips. At the most recent evaluation, patient functional status was rated by the Harris Hip Score (HHS) and radiographic changes were graded according to Tönnis criteria. Complications were defined as Tönnis grade >2 or hip requiring further surgery. Univariate analysis was used to explore factors associated with complications. Spearman's rank correlation coefficient was calculated between HHS and Tönnis grading. At mean follow-up of 4.4 ± 2.6 (range 1.1-9.5) years, mean HHS was 87.4. Tönnis grading was rated as 0 in 10 hips, 1 in 5 hips, 2 in 2 hips, and 3 in 3 hips. Avascular necrosis of the femoral head as a complication developed in 3 hips (15%). Clinical parameters including age at surgery, duration of follow-up and diagnosis were not significantly associated with postoperative complications. A negative correlation between HHS and Tönnis grade was shown by Spearman's rank correlation (rs = -0.49, p = 0.03). The AMG can be safely recommended as an adjunct bone graft procedure when performing anterior open reduction of adolescent and active adult hip disorders.

Core decompression or quadratus femoris muscle pedicle bone grafting for nontraumatic osteonecrosis of the femoral head: A randomized control study.

Background:The traditional management for osteonecrosis of the femoral head (ONFH) includes core decompression (CD) and quadratus femoris muscle pedicle bone graft (QF-MPBG). The aim of this study was to investigate the effects of CD and QF-MPBG on the patients with nontraumatic ONFH in an early stage.Materials and Methods:39 patients (47 hips) with ONFH in an early stage (Ficat Stage I or II) were randomly divided into two groups according to random number table method. One group was treated with CD and cancellous bone grafting. Another group was treated QF-MPBG with cancellous bone grafting. The hip function was evaluated using Harris hip score (HHS). The repair of the femoral head was estimated through X-ray, computed tomography (CT), or magnetic resonance imaging (MRI). The surgical time and intraoperative blood loss was calculated.Results:All patients were followed for an average 2.5 years (range from 1.5 to 4 years). Two hips in CD group progressed into stage 3 and three hips in QF-MPBG group processed into stage 3. No patient accepted the THA at the last followup. The HHSs significantly increased in both groups after surgery (P < 0.05). No statistical differences were found between CD and QF-MPBG groups in postoperative HHSs at last followup (P > 0.05). X-ray and CT showed that the femoral head did not progress to collapse after operation in both groups. In addition, MRI showed that the edema signals decreased. However, the surgical time was longer in QF-MPBG group than that in CD group (P < 0.05). The intraoperative blood loss was more in QF-MPBG than that in CD group (P < 0.05).Conclusion:The CD with bone graft could relieve hip pain, improve hip function with much lesser surgical trauma compared to QF-MPBG. Hence, the CD with bone graft should be generally used for the treatment of patients with an early stage (Ficat Stage I or II) ONFH.
