Efficacy of Autologous Adult Live-Cultured Osteoblast (AALCO) Implantation in Avascular Necrosis of the Femoral Head: A Mid-Term Outcome Analysis.

Avascular Necrosis (AVN) of the femoral head, a condition characterized by the interruption of blood supply leading to bone tissue death, presents significant therapeutic challenges. Recent advancements in orthobiologics, including the use of Autologous Adult Live-Cultured Osteoblasts (AALCO), combined with core decompression, offer a novel approach for managing AVN. This study assesses the efficacy of this treatment modality in improving functional outcomes and hindering disease progression. This retrospective observational study encompassed 30 patients treated between 2020 and 2023 for idiopathic AVN of the femoral head, grades I to III, who had not responded to conservative treatment. Patients were excluded based on specific criteria including age, secondary AVN causes, and certain health conditions. The treatment involved a two-stage surgical procedure under spinal anesthesia with OSSGROW® for AALCO generation. Post-operative care emphasized early mobilization, DVT prevention, and avoidance of NSAIDs. Outcome measures were evaluated using the Visual Analog Scale (VAS) for pain, modified Harris Hip Score, and annual MRI imaging for up to 36months. Among 26 patients (41 hips) completing the study, statistically significant improvements in pain and hip functionality were documented, alongside positive radiological signs of osteogenesis in the majority of cases. However, four instances required advancement to total hip replacement due to disease progression. The combination of core decompression and AALCO implantation shows promise as an effective treatment for AVN of the femoral head, with notable improvements in functional and radiological outcomes. This study supports the potential of orthobiologic approaches in AVN treatment, warranting further investigation through comprehensive randomized controlled trials.

Legg-Calvé-Perthes Disease: Diagnosis, Decision Making, and Outcome.

Legg-Calvé-Perthes disease (LCPD), or idiopathic avascular necrosis of the proximal capital femoral epiphysis in children, has a variable presentation and can result in significant femoral head deformity that can lead to long-term functional deficits. Plain radiographic imaging is crucial in diagnosing LCPD and guiding treatment. Although the etiology of LCPD remains unknown, the evolution of the disease has been well characterized to include the phases of ischemia, revascularization, and reossification. The mechanical weakening during these phases of healing place the femoral head at high risk of deformity. Treatment of LCPD, therefore, focuses on minimizing deformity through operative and nonoperative strategies to reduce the risk of premature osteoarthritis. Advanced imaging using perfusion MRI may refine surgical decision making in the future, and biological treatments to improve femoral head healing are on the horizon.

Case Report: Idiopathic avascular necrosis of the femoral head following pregnancy

Background: Hip pain during pregnancy is very common, but avascular necrosis (AVN) represents a very rare entity. Osteonecrosis of the head of the femur during the pregnancy, or shortly after the pregnancy, is a rare clinical problem. Little is known about pregnancy as an etiological factor for AVN of the femoral head. Case: In this case report, a documented case of femoral head osteonecrosis, a rare complication after pregnancy is presented. The patient presented with complaints of pain in the left hip that gradually worsened and led to restriction of movement. The patient was advised an X-ray, which showed a fracture of neck of the left femur, and an MRI following the X-ray revealed features of AVN of the hip. The patient was later taken for total hip arthroplasty, which was uneventful. On follow-up, the patient had relief from her symptoms and had no complications. Alcoholism, steroid use, systemic lupus erythematosus, organ transplantation (particularly following kidney or bone marrow transplantation), dyslipidemia (particularly hypertriglyceridemia), Gaucher disease, decompression sickness, and drepanocytosis are known risk factors for osteonecrosis. We can list pro-coagulation abnormalities, chemotherapy, and HIV among the less established factors. Here, we present a case of a patient with postpartum AVN of the femoral head that suffered AVN of the left hip in the post-partum period, her symptom of hip pain was neglected as a benign cause initially, which led to aggressive treatment (total hip arthroplasty) at a young age. Conclusions: Having high suspicion of the diagnosis of AVN and a low threshold for magnetic resonance imaging (MRI) imaging in a pregnant woman with hip pain is a requirement to avoid complications. This case highlights the need for high suspicion of osteonecrosis as a cause of hip pain in the post-partum period.

"Waiting for the best day of your life". A qualitative interview study of patients' and clinicians' experiences of Perthes' disease.

Perthes' disease is an idiopathic avascular necrosis of the developing femoral head, often causing deformity that impairs physical function. Current treatments aim to optimize the joint reaction force across the hip by enhancing congruency between the acetabulum and femoral head. Despite a century of research, there is no consensus regarding the optimal treatment. The aim of this study was to describe the experiences of children, their families, and clinicians when considering the treatment of Perthes' disease. A qualitative study gathered information from children and their families affected by Perthes' disease, along with treating clinicians. Interviews followed a coding framework, with the interview schedule informed by behavioural theory and patient and public involvement. Transcripts were analyzed using the framework method. A total of 24 interviews took place, with 12 child/family dyads and 12 clinicians from UK NHS centres. Interviews identified widespread variation of routine care. Children/their families recounted positive experiences when included in the decision-making process for treatment. There is a strong desire from clinicians and children/families for consistent guidance from everyone involved in care, which should be based on clinical consensus. This is the first study to describe how children/families and clinicians experienced receiving or providing treatment in Perthes' disease. The results indicate the need for robust evidence to support treatment decisions. Children and families valued feeling involved in the clinical decision-making process. Clinicians acknowledged the central importance of providing patient-centred care, particularly in the absence of robust evidence to guide the optimal treatment decisions. This study will inform a future Delphi project to develop clinical consensus guidelines for the treatment of Perthes' disease.

Lupus nephritis with clinical and laboratory features of humoral immune deficiency in a 29-year-old female with a novel NCF1 variant consistent with autosomal recessive chronic granulomatous disease

Chronic Granulomatous Disease (CGD) is a rare, inherited disorder of the innate immune system characterized by defects in the phagocyte NADPH oxidase complex. This results in poor phagocyte function causing frequent infections (bacterial and fungal) and chronic inflammation. Here we discuss a rare presentation of lupus nephritis and antibody deficiency in an adult female patient with a novel homozygous nonsense mutation in the NCF-1 gene causing autosomal recessive CGD.Our patient is a 29-year-old female with history of ITP, biopsy-confirmed lupus nephritis, systemic lupus erythematosus (SLE), idiopathic avascular necrosis of the hip, and previous diagnosis of common variable immune deficiency (CVID) treated with Immunoglobulin replacement therapy (IVIG). She presented to our clinic to establish care in the setting of persistent skin abscesses/cellulitis, poor wound healing, necrotic lymphadenitis, and recurrent urinary tract infections and pneumonia despite years of IVIG therapy. She had near-normal total IgG, absent IgA and IgE, and protective vaccine antibody titers (pneumococcus, diphtheria, and tetanus) prior to the start of IVIG. Immunophenotyping demonstrated quantitatively normal number of total B cells, absent CD27+ memory B cells, and normal T cell subsets. She had reassuring lymphocyte proliferation with mitogen stimulation and normal TLR function. Dihydrorhodamine (DHR) flow cytometric assay demonstrated abnormally low neutrophil oxidative burst activity. Gene sequencing revealed homozygous nonsense mutation in the NCF-1 gene (c.75-76del; pY26Hfs*26) and a pathogenic heterozygous variant in FANCM (c.3732-3735dup; p. Leu1246Asnfs*8). She was started on daily prophylactic trimethoprim-sulfamethoxazole and itraconazole. She has marked decrease in infections/hospitalizations and her lupus nephritis is well controlled with hydroxy-chloroquine. She is being referred to the NIH for HSCT evaluation. The majority of CGD cases in the United States are due to X-linked CGD (70%) and AR variants in NCF1 (20%). While rare, discoid lupus erythematosus and SLE have been documented with X-linked forms of CGD. Similarly, there are few case reports of antibody deficiency in patients with CGD. This is the first documented case of AR CGD with SLE/lupus nephritis and humoral immune defects. Additionally, we report a disease-causing, novel variant in the NCF1 gene. This case report adds to the existing literature on CGD and associated diseases.

Mycoplasma as a possible trigger for the development of idiopathic avascular necrosis of the femoral head

BACKGROUND: The death of bone tissue cells with impaired blood supply, followed by the development of secondary arthrosis/arthritis of the adjacent joint, is most characteristic of osteonecrosis of the femoral head. This condition is common in young patients mainly in men of working age. Hip arthroplasty at a young age has a high risk of loosening of the endoprosthesis components, which can lead to many repeated surgical interventions. In recent years, hypotheses about the possible role of infectious agents in articular pathology have been discussed, as evidenced by the detection of specific antibodies and antigens of pathogens in the joint fluid and periarticular tissues. Mycoplasmas can trigger the development of osteonecrosis because the bone marrow is the main depot and source of endogenous reinfection (when immunity is weakened).
 АIM: This study aimed to identify signs of the presence of mycoplasmas in the soft tissues of the hip joint and bone marrow of the femur during hip arthroplasty in patients with idiopathic avascular necrosis of the femoral head.
 MATERIALS AND METHODS: Clinical and laboratory data of 36 patients with idiopathic aseptic necrosis of the femoral head who underwent total hip arthroplasty were analyzed, and 11.1% of the patients had a history of sexually transmitted diseases. The tissues of the synovium and bone marrow were examined by polymerase chain reaction for the presence of DNA to sexually transmitted infections.
 RESULTS: The average age of the patients was 42.7 years, and the average period from disease onset to the time of surgery was 46.2 months. Bilateral joint damage was found in 78% of cases, and 91.7% of the patients had stage 4 femoral head disease (ARCO). The preoperative Harris score was 33.7 points on average. In history, 4 (11.1%) patients had sexually transmitted diseases. During the study, when analyzing tissue samples of the synovial membrane and bone marrow, DNA fragments of Chlamydia trachomatis, Mycoplasma genitalium, Ureaplasma spp., and M. hominis were not isolated in any case, including in patients with previous mycoplasma and chlamydial infection.
 CONCLUSION: The absence of mycoplasma suggests that a history of sexually transmitted diseases does not significantly affect the outcomes of hip arthroplasty in aseptic necrosis of the femoral head.

Preiser's Disease-Current Concepts of Etiology and Management.

The term Preiser's disease typically is used to describe idiopathic avascular necrosis of the scaphoid, but there have been a number of putative etiologies considered. It is rare and the natural history is not fully understood. Management of the condition should be based on patient factors as well as the stage of disease with regard to the scaphoid and the surrounding wrist. This chapter appraises the available evidence and aims to provide the reader with a framework to manage this rare condition.

Avascular necrosis of the first metatarsal head in adolescence: A case report.

Avascular necrosis (AVN) of the first metatarsal (MTT) head is an uncommon condition and it occurs most often as a complication after capital osteotomy in correction of hallux valgus deformity. Idiopathic osteonecrosis of the first MTT head in adolescent are rare and treatment is challenging (1,2). Many conditions have been proposed as predisposing factors of AVN, including trauma, hemoglobinopathies such as sickle-cell disease, steroid therapy, Cushing's disease, alcoholism, Gaucher's disease, Caisson's disease, and irradiation (3,4). However, etiology remains elusive. We described a case of an idiopathic AVN of the 1st MTT in adolescent treated by dorsal closing-wedge osteotomy, which to the authors' knowledge has not been described before.

Total Hip Arthroplasty via direct anterior approach for osteonecrosis; comparison with primary hip osteoarthritis in a mid term follow up

BackgroundTo determine the mid-term outcomes of conventional cementless Total Hip Arthroplasty (THA) in patients with avascular necrosis (AVN) of the femoral head and compare to patients with primary hip osteoarthritis (OA). MethodA total of 330 consecutive primary THA procedures (AVN and OA) performed between 2010 and 2013 by a single surgeon and in a single center using the direct anterior approach (DAA) were included. Assessments including SF-36, WOMAC, and Harris Hip Scores (HHS) were retrieved from patients before the surgery and at the latest follow-up. Clinical and functional outcomes were compared between the AVN and OA groups. ResultsA total of 294 consecutive THA (AVN = 107, OA = 187) with 104.4 ± 6.2 months follow-up were analyzed, which AVN patients were significantly younger (32.0 vs. 59.6 y/o). Corticosteroid 34 (31.8%), idiopathic AVN 31 (29.0%) and use of unapproved weight gain supplements (UWGS) 23 (21.5%) were the main reasons for AVN. Despite that preoperative scores were comparable (P > 0.05), the HHS, SF-36, and WOMAC scores are significantly higher in the AVN group after THA surgery (P < 0.05). Moreover, flexion and abduction ROM were significantly higher in the AVN group (P < 0.05). Regarding each complication, no significant difference was observed between groups. In the whole sample, there were 5 (1.7%) revisions due to loosening of acetabular components, all the OA group (P > 0.05). ConclusionConventional cementless THA with highly cross-linked polyethylene provides satisfactory mid-term results in patients with AVN with a low rate of postoperative complications. Compared to primary OA patients, this group reaches superior postoperative scores.

A Retrospective Observational Study to Compare the Outcome of Various Treatment Modalities of Idiopathic Avascular Necrosis of Hip.

Avascular necrosis (AVN) of hip of the femoral head is increasingly seen in young age, disabling them in their productive years of life. Available treatment options need to be evaluated. The aim was to compare the outcome of various treatments at different stages of AVN hip. A retrospective observational study was done in patients with idiopathic AVN hip, who had undergone different treatment modalities. The data of the included patients at different time intervals were compared. All patients were graded with the help of Harris Hip Score (HHS), and their outcome was evaluated. The age distribution of patients showed that nearly 80% of them were below the age of 50 years. The patients were presenting more often in Ficat and Arlet stage 4 compared to earlier stages. The patients in stage 1 were treated by core decompression alone, which produced good-to-excellent results in 4 of 7 (57.1%) patients. Patients in stage 2 and 3 were treated by core decompression with fibular bone grafting and had good-to-excellent results in 6 of 8 (75%) patients. In stage 4 of disease, cemented total hip replacement (THR) was done, and it produced good-to-excellent results in 13 of 15 (86.6%) patients. In the early stage of disease, core decompression with and without bone grafting produced satisfactory results. In an advanced stage of AVN, THR is an excellent treatment option.

Avascular Necrosis of the Scaphoid-Preiser Disease: Outcomes of 39 Surgical Cases

There is no established treatment standard for patients with idiopathic avascular necrosis of the scaphoid, also known as Preiser Disease. We evaluated outcomes of operative interventions performed for patients diagnosed with Preiser Disease and assessed scaphoid morphology in the contralateral wrists. We performed a retrospective review of all patients undergoing surgery for Preiser disease between 1987 and 2019 at our institution. A total of 39 wrists in 38 patients were identified. The mean age was 37 years at the time of surgery, and the median follow-up time was 5.3 years. The patients were classified according to the Herbert and Kalainov classifications. Pre- and postoperative pain and functional outcomes were evaluated, and Mayo Wrist Scores were calculated. Reoperations for complications were recorded. Scaphoid shapes were assessed for wide/type 1 and slender/type 2 scaphoids in the contralateral unaffected wrist in patients with unilateral disease. Overall, pain and Mayo Wrist Scores improved, while flexion/extension decreased slightly and grip strength remained stable. In a comparison of the 2 main surgery groups, 17 wrists with a pedicled vascular bone graft and 12 wrists with salvage surgery (4-corner fusion/proximal row carpectomy) showed similar functional outcomes. Similar outcome scores were found regardless of preoperative Herbert or Kalainov classifications. Radiographic morphologic evaluation of the contralateral side determined that 4 of 8 patients had a slender scaphoid shape, which has been shown to have a more limited vascular network when compared to full scaphoids. A treatment algorithm of Preiser disease is lacking and the optimal surgical treatment remains controversial. Pedicled vascular bone grafts had similar functional outcomes as salvage procedures, but preserving the scaphoid was possible in 70% of the pedicled vascular bone graft cases. A slender scaphoid is potentially more common in patients with Preiser disease who undergo surgery. Therapeutic IV.

Management of Posttraumatic Avascular Necrosis of the Proximal Humerus.

The etiology of avascular necrosis (AVN) of the proximal humerus can be classified as idiopathic or posttraumatic, the latter being mainly due to proximal humerus fractures. Evidence suggests that posttraumatic AVN may require surgical intervention more often than idiopathic AVN of the proximal humerus. This article provides a comprehensive review of the management of posttraumatic AVN of the proximal humerus. Early stage AVN (stages 1 to 3) is commonly treated with nonoperative intervention or core decompression of the humeral head, whereas later stage disease (stages 4 and 5) may require hemiarthroplasty or total shoulder arthroplasty to restore function.

What are the newest outcomes about Legg-Calve-Perthes disease etiology after 110 years over its discovering ? – literature review

Idiopathic avascular necrosis of the femoral head, known as Legg-Calve-Perthes disease (LCPD), is one of the most common necrosis among paediatric patients. Although it was described over 110 years ago its aetiology is still not established. Neither have effective treatment methods, which main aim is to maintain the joint with a full range of motion and to reduce the risk of developing degenerative changes. According to the literature, the exact aetiology of LCPD has still not been established. Increasingly, immunological and genetic disorders are highlighted in the literature, which may be an important cause of disease development. However, the number of reliable studies on this subject is very limited. Once again, the influence of various risk factors present in fetal life has been analysed, but in a study with a significantly larger group of subjects. It has been repeatedly stressed that age, stage and radiological classification have a very important influence on the choice of treatment method and its effectiveness. Another important aspect is the need for reliable clinical trials to determine the effectiveness of bisphosphonate drugs and BMPs (bone morphogenetic proteins). In all studies, the need to perform more studies, on quantitatively larger groups of subjects, is significantly emphasized.

Core Decompression and Bone Marrow Aspirate Concentrate in the Treatment of Femoral Head Avascular Necrosis in Pediatric Sickle Cell Disease: Can We Improve Natural History?

Femoral head avascular necrosis (AVN) affects between 10% and 41% of children with sickle cell disease (SCD), resulting in the development of proximal femoral deformity and residual hip pain in the majority of patients without treatment. There have been multiple adult studies published on the outcomes of core decompression with and without the use of bone marrow aspirate concentrate (BMAC) injection both in idiopathic and SCD-related AVN with promising results, however, few studies have reported on outcomes in skeletally immature patients. This study sought to report on a single surgeon's outcomes for core decompression with BMAC injection in pediatric patients with AVN of the femoral head secondary to underlying SCD. A single-center, retrospective review was performed for pediatric patients undergoing core decompression with BMAC injection for femoral head AVN in patients with SCD with a minimum of 12-month follow-up. Demographic, radiographic, and clinical variable were collected. Patients were subdivided based upon presence of open femoral physes at the time of surgery. Successful treatment was defined as the ability to return to activities without limitations. A total of 13 patients (average age 14.1±2.8 y, 84.6% male, 6 skeletally immature and 7 skeletally mature) with 18 affected extremities were identified. Open physes were present in 50% of operative extremities. Skeletally immature patient demonstrated reconstitution of the femoral head in 78% of cases and 89% demonstrated regression of at least 1 Steinberg grade and none had progression. Skeletally immature patients were significantly more likely to return to activities (100% vs. 55.6%, P=0.023) and achieve a final Tonnis grade <2 (89% vs. 44%, P=0.046). Core decompression appears to alter the natural history of AVN in skeletally immature patients with SCD. Skeletal immaturity was a positive prognostic factor for the ability to return to activities without pain and achieve a lower Tonnis grade at final follow-up.

Outcome of Varus Derotation Osteotomy for Containment of Femoral Head in Advanced Perthes Disease

Background: Legg-Calve-Perthes (LCP) disease, or idiopathic avascular necrosis of the femoral head occurs during early childhood and is caused by impaired circulation in the femoral head. Varus derotation osteotomy (VDO) was described over half a century ago, and is now a popular method for the operative treatment of Perthes disease.&#x0D; Objective: To find out the clinical and radiological outcome of varus derotation osteotomy for containment of femoral head in advanced Perthes disease.&#x0D; Materials and Methods: This observational study was conducted in the Department of Orthopaedic Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka from March 2015 to September 2017. Total 20 cases of advanced Perthes disease were enrolled. Pre- and post-operative period were evaluated by interview and clinical examination by using a semi-structured questionnaire. Demographic and clinical information were recorded. All patients had a pre- and post-operative x-rays. We used visual analog scales (VAS) for scoring pain; Wiberg’s central edge angle, epiphyseal extraction index, neck shaft angle and Larson (Iowa) hip score were used to assess the outcome of VDO. Comparison of continuous variables between the two groups was made with Student’s t-tests. Comparison of proportions between Herring groups B and C were made with chi-square tests. p&lt;0.05 was considered as significant. All the data were compiled and sorted properly and the quantitative data were analyzed statistically by using Statistical Package for Social Sciences (SPSS 22.0).&#x0D; Results: In the present study, mean visual analog scale (VAS) score and epiphyseal extraction index (EEI) were significantly (p&lt;0.001) lower in Herring Group B in comparison to that of Group C, but mean WCEA, NSA and HLS were significantly (p&lt;0.001) higher in Herring Group B in comparison to that of Group C.&#x0D; Conclusion: Varus osteotomy gives good results in children aged 6–12 years who do not exhibit any femoral head deformity or flattening, especially those with good containment in abduction in advance Perthes disease.&#x0D; J Enam Med Col 2020; 10(2): 79-85

Legg-Calve-Perthes disease.

We report a case of a 9-year-old male who presented with limping gait. The primary concern of the parents was that, he started walking in an awkward fashion two months ago. The birth and developmental history were uneventful. Child complaint of mild inconsistent pain in left hip joint. On observation in standing posture, asymmetry was noted as he was bearing less weight on left lower limb due to pain. On examination, in supine lying, active as well as passive abduction of left hip were terminally limited by pain. When he was made to stand on right leg, pelvis was neutral. On the other hand, trunk shifted to left side while he attempted single leg standing on left leg and it was difficult to maintain balance. Thus, Trendelenburg sign was positive. Trendelenburg gait was evident as the trunk shifted to the stance side. X-ray reveals smaller and compressed femoral epiphyseal size with blurred epiphyseal plate on the left side. Stage I changes in imaging were noted according to Waldenstrom's classification along with Stulberg class III of Perthes disease. Legg-Calve-Perthes disease is insidious onset idiopathic avascular necrosis of femoral epiphysis in children, commonly between five to eight years of age. Physiotherapy intervention comprised active range of motion of left hip joint in non-weight bearing position, isometric exercise of gluteal muscles, prescription of weight relieving trilateral orthosis, parent and child education about de-loading of hip joint and avoiding high impact activities. Containment surgery for left hip was planned by orthopaedic surgeon.

SERIAL IMAGING OF A CHILD WITH LEGG-CALVE-PERTHES DISEASE AT BETHESDA HOSPITAL, YOGYAKARTA: A CASE REPORT

Background: Legg-Calve-Perthes disease (LCPD) is a rare condition of idiopathic avascular necrosis of the femoral head, mostly affects children under fifteen old. Most cases only affect one femoral head; bilateral involvement only occurs in about 15% of cases. Early diagnosis and prompt intervention play an important role in the prognosis to prevent degenerative damage on the bones and joints.&#x0D; Objective: To describe a case of Legg-Calve-Perthes disease in a 9-year-old boy in Bethesda Hospital, Yogyakarta.&#x0D; Case Description: A 9-year-old boy came with one month history of worsening pelvic pain to Bethesda Hospital, Yogyakarta. He also showed limping and limited mobility. Initial imaging studies did not find any abnormalities. Further follow-up with MSCT scan related to the complaint of persistent pain showed defects of left hip joint indicating Legg-Calve-Perthes disease. The patient undergone skin traction treatment which shows modest improvement on serial radiographic examinations during hospital admission. &#x0D; Conclusion: The rarity of LCPD warrant thorough imaging studies on children with unexplainable severe hip joint pain. Treatment should be initiated as early as possible after diagnosis to prevent further bone damage and worsening prognosis. Conservative management with skin traction would benefit the patient in restoring normal anatomy and optimal joint congruence to prevent degenerative damage to the joints.

Mid-Carpal Joint Sparing Procedure for Idiopathic Avascular Necrosis of Capitate

Background Avascular necrosis of the capitate (AVNC) is an uncommon pathology of the wrist. Several procedures have been described for the treatment of AVNC. The type of treatment varies depending upon the stages. In early stages, revascularization procedures are performed. If secondary osteoarthritis develops, then the treatment options include intercarpal fusion, four corner fusion, prosthesis replacement of the capitate, tendon interposition, and wrist arthrodesis. No long-term study is available for choosing an appropriate method of the treatment for AVNC. Case Description Herein, we report a case of AVNC that was managed by hemi-resection of the capitate with capito-hamate fusion and tendon interposition. One year after surgery, patient was asymptomatic and radiographs revealed fusion of capito-hamate joint and maintenance of the mid-carpal joint space. There was no evidence of carpal collapse. Literature Review All the literature about mid-carpal joint sparing (MCJS) procedures has been reviewed in this report. This is a goal behind writing of this case report as there have been very few publications about these procedures. Clinical Relevance This case illustrates the successful treatment of AVNC by MCJS procedure. The intercarpal fusion and the four corner fusion are one time procedures, and these can be used if the MCJS procedure fails or sometimes, as primary procedure, if the patient gives consent for the same. It appears prudent to save arthrodesis procedures for the future.
