Total Hip Arthroplasty in Ankylosing Spondylitis: A Case Report of Ankylosed Hip.

Ankylosing spondylitis (AS) is a chronic inflammatory arthritic disease that primarily affects the axial skeleton, and its association with the secondary development of osteoarthritis (OA) in peripheral joints, particularly the hips, is increasingly recognized. This case report elucidates the diagnostic and therapeutic challenges encountered in a patient with bilateral hip osteoarthritis secondary to AS. The patient's medical history included AS and a failed attempt at core decompression of the left hip joint. The patient was managed with total hip arthroplasty (THA) on the left side due to persistent symptoms. Total hip arthroplasty on the left side involved a meticulous surgical approach, addressing the unique challenges posed by underlying ankylosis. The procedure was conducted uneventfully, with the implantation of a modular femoral head, uncemented femoral stem, and modular shell. Postoperatively, the patient experienced significant pain relief and improved functionality. Successful rehabilitation and management were integral to the overall positive outcome. This case report highlights the complex interplay between AS and hip osteoarthritis, emphasizing the importance of tailored diagnostic and therapeutic strategies. Successful total hip arthroplasty in the setting of AS-related hip osteoarthritis suggests that joint replacement can be effective, but ongoing research is necessary to optimize surgical planning and long-term outcomes in this patient population.

A Rare Case of Monostotic Fibrous Dysplasia of the Femoral Neck With Pathological Fracture: A Case Report.

Fibrous dysplasia is a rare benign bone disorder characterized by the replacement of normal bone with fibroblastic and osteoblastic tissue. We present a case of monostotic fibrous dysplasia in a 25-year-old male patient. The case highlights the clinical presentation, radiographic features, and management approach for this condition. This report aims to contribute to the understanding of fibrous dysplasia and its management options. A 25-year-old male presented with a chief complaint of persistent left hip pain. The pain was described as a dull ache, associated with difficulty in weight-bearing activities. There was no history of trauma or constitutional symptoms. Physical examination revealed externally rotated left lower limb. Range of motion of the left hip could not be assessed due to pain, with no neurological deficits noted. Initial imaging included plain radiographs of the right femur, which demonstrated a radiolucent lesion with a ground-glass appearance and cortical thinning. Magnetic resonance imaging of both hip joints reveals an irregular T2 hyperintense and T1 hypointense lesion involving the left femoral neck; moreover, few tiny cystic spaces are seen within the lesion. Part of the lesion is extending into the superior-lateral aspect of the femoral head and surrounding bone marrow edema with minimal left hip joint effusion, features suggestive of a primary bony tumour. Plain computed tomography (CT) of the hip joint and pelvis was suggestive of an expansile lytic lesion with thin bony septation within and thick sclerotic margin in the left femoral head and greater trochanter associated with sub-capital femoral neck fracture suggestive of bone neoplasm (? giant cell tumour > simple bone cyst). A bone biopsy was performed, and histopathological examination confirmed the diagnosis of fibrous dysplasia, with characteristic woven bone and fibrous stroma. In this case, after confirming the diagnosis, the patient was managed with total hip arthroplasty on the left side. Monostotic fibrous dysplasia is a rare benign bone disorder that can present with various clinical manifestations. Timely diagnosis through a combination of clinical, radiographic, and histopathological assessments is crucial. Management should be tailored to the patient's symptoms.

Intraoperative Foot Positioning During Percutaneous Calcaneal Fixation: A Technical Note.

Percutaneous screw fixation is a good modality for operative management of extra-articular and some intra-articular fractures of the calcaneum amenable to closed reduction. Tongue-type calcaneal fractures with a dislocated posterior facet are usually treated with percutaneous fixation. When treating calcaneal fractures with substantial soft tissue compromise, particularly open fractures, percutaneous reduction techniques are crucial. They also provide patients with local or systemic contraindications to open reduction with a therapeutic option. We describe the intraoperative positioning of the foot using a lithotomy stirrup during percutaneous fixation of the calcaneal fractures with minimum manipulation of the foot and C-arm and consistent imaging.

A Rare Case of Giant Cell Tumour of the Medial Epicondyle of the Humerus Managed With Curettage and Bone Grafting.

Giant cell tumours (GCTs) of the medial epicondyle of the humerus are rare. These are generally benign tumours but have the potential to be locally aggressive. They can invade the adjacent joint or the surrounding soft tissues or, in rare cases, cause distant metastasis. Locally aggressive GCTs are generally treated with wide resection, curettage, and bone grafting, followed by joint reconstructions. Here we present a case of a 49-year-old female with a history of swelling over the medial epicondyle of the humerus for six months. The patient was diagnosed with a locally aggressive GCT and was managed with wide excision of the tumour followed by sandwich bone grafting. A two-year follow-up of the patient shows no signs of recurrence. The patient is pain-free and has decent elbow function.

Use of Endobutton for Small Avulsion Fracture of Coronoid in the Terrible Triad of the Elbow: A Case Report.

The terrible triad (TT) of the elbow consists of coronoid process (CP) fracture, fracture of the radial head (RH), and posterior dislocation. Although the coronoid is an important anterior stabilizer, it is still unclear how to treat comminuted coronoid fractures. Poor fixation of the CP tends to result in posterolateral instability at the elbow joint and often in chronic instability. The ligamentous injuries also cause instability in elbow dislocations and should be suspected. There are various techniques available for coronoid fracture fixation. In this case report, we want to highlight our experience managing a 47-year-old male with posterior dislocation of the elbow after computed tomography (CT) confirmed that the patient had an RH fracture with an avulsion fracture of the coronoid. This TT of the elbow was managed with the help of an endobutton and a Herbert screw for coronoid avulsion fracture and RH fracture, respectively, through a lateral (Kocher) approach in our tertiary care hospital with satisfactory results. The use of endobutton is recommended in type 1 and type 2 coronoid fractures with no or minimal capsular attachment for good suspensory effect, and it emphasizes the possibility of associated coronoid fracture in case of posterior elbow dislocation. This case report emphasizes the fixation of even small fragments of the coronoid fracture for better stability and early mobilization. Postoperative rehabilitation involved using a hinged brace and early mobilization to avoid a stiff elbow and periodic X-rays to check the heterotopic ossification risk.

A Review on the Efficacy of Extraosseous Local Infiltration of Multimodal Drug Cocktail for Pain Management After Total Knee or Hip Arthroplasty.

Total knee arthroplasty (TKA) patients express minimal comfort regarding postoperative pain management. The use of parenteral opioids or epidural analgesia may have unfavorable adverse impacts that interfere with quick healing and rehabilitation. It is uncertain if periarticular multimodal drug injections (PMDI) are effective at easing pain following total knee or total hip arthroplasty (THA). We conducted this study to assess the effectiveness of PMDI following TKA or THA. Articles were sourced using the following keywords on Pubmed, Google scholar, and the Web of Science: multimodal drug cocktail in total knee arthroplasty OR hip arthroplasty, periarticular injections AND multimodal drug cocktail, epidural versus periarticular injections AND pain management after total joint arthroplasty. After screening 438 articles and abstracts, 200 pertinent studies were found, of which a total of 10 articles were included in the study. From this review, we want to conclude that despite the various ways to address postoperative pain, there is no acknowledged gold standard for postoperative pain management following total joint arthroplasty. To reduce narcotic intake and prevent narcotic-related adverse reactions, multimodal techniques utilizing regional anesthetics appear to be on the rise such as periarticular injections, or patient-controlled analgesia with or without femoral nerve block. Even though the ideal duration and kind of medications are unclear, preoperative pain management or preemptive analgesia with anti-inflammatory drugs and opioid analgesics seem to be useful in lowering postoperative pain.

Outcome Analysis of Distal End Radius Fractures Managed With Antegrade Intramedullary K-wire Fixation.

Background The most frequent upper limb fractures are distal end radius fractures, accounting for around 17% of all fractures in clinical practice. Falling on an outstretched hand is the most common mechanism of injury, and it can also occur in high-energy trauma in young individuals. A minimally invasive technique of percutaneous pinning was introduced to sustain the fracture's reduction after manipulation and avoid the re-displacement of fractured fragments. Antegrade intramedullary K-wire fixation is a cost-efficient procedure that can be done in rural settings. Methodology A total of 30 patients with fractures of the distal end radius managed with antegrade intramedullary K-wire fixation were included in the study. Operated patients were followed up at one month, three months, and six months for functional assessment. An X-ray was taken on every follow-up to assess the union and implant positioning. Results In our study, the mean age was 45.6 years. Out of the 30 patients, 12 were males and 18 were females. All 30 patients at the final follow-up showed good functional improvement, with statistically significant improvements in palmar flexion, adduction and abduction, and pain scale scores. Conclusions Antegrade K-wire fixation is an effective technique for fractures of the distal end radius that can be performed in rural settings with effective results.

Surgical Repair of Achilles Tendon Rupture by Turn-O-Plasty: A Case Report.

Achilles tendon rupture has been a difficult problem for surgeons, especially in older patients, since tendon strength and flexibility are significantly diminished compared to young people. The Achilles tendon endures the highest tensile stresses in the body while running, leaping, and skipping, with tensile loads up to 10 times body weight. There are many treatment options for Achilles tendon repair, including open surgery, percutaneous repair, and ultrasound therapy. Open repair has the danger of scar dehiscence owing to poor skin conditions. In contrast, small invasive operations have the risk of sural nerve damage and a higher possibility of re-rupture. The gold standard method or approach is still under question. Plantar flexion in the ankle is primarily a function of the Achilles tendon; hence, post-operative plantar flexion is a significant determinant of the desired result. We present the case of a 57-year-old male farmer suffering from a left Achilles tendon rupture due to trivial trauma. This rupture consisted of a significant defect, present in the watershed area with signs of tendinosis at the insertion of the tendon. The patient was managed surgically by turn-o-plasty and the degenerated insertion site was augmented with the help of a suture disc. This case report focuses on surgical management by turn-o-plasty for significant defects in the Achilles tendon by using a suture disc to augment the defect.

Limb Salvage Surgery With Mega-Prosthesis in a Case of Chondrosarcoma: A Case Report.

Chondrosarcoma is a kind of bone tumor that can be anywhere in the body but most commonly affects the pelvis, glenohumeral joint, proximal femur, and proximal one-third of the tibia including condyles. It accounts for 20-25% of all bone sarcomas. Chondrosarcomas with clear cell variants are extremely uncommon, making up just around 6% of all cases. We are presenting a case of a 52-year-old male with a bony lesion over the epiphysis of the left tibia. He was managed with resection of the tumor followed by a limb salvage procedure with mega-prosthesis. Chondrosarcoma affects men in the third to fourth decades of their life more commonly than females. Long-standing localized pain over a prolonged duration is the most common presenting symptom. There are various treatment modalities available for clear cell chondrosarcoma, ranging from wide local resection and intralesional therapy to amputation. The decision of tumor resection followed by prosthesis was chosen over amputation here, as the patient had the lesion for 2 years and there were no signs suggestive of metastasis after thorough screening. Limb salvage gave a better outcome for the patient in our study. A large-segment prosthesis is a suitable reconstructive alternative to amputation. At the majority of the anatomical sites where the prosthesis was employed, the functional results were good or exceptional after this type of treatment. The patient now has a functional limb and is able to resume his life as before, making mega-prosthesis a better alternative and treatment of choice for patients with large lesions.

Dual mobility THR: Resolving instability and providing near normal range of movement.

BACKGROUND: Dislocation is a common complication of Total Hip Replacement (THR), particularly when performed in primary (indications with increased risk of instability) and in revision scenarios. Dual mobility THR (DMTHR) minimizes the risk of instability in such scenarios, however most of the evidence is from western literature. Results of DMTHR in Indian scenarios where patient want to go back to their normal routine activities of squatting and sitting cross-legged is lacking. The aim of our study was to evaluate the short to mid-term results of DMTHR for varied indications (both primary and revision) in Indian scenario. To evaluate the outcome of the DMTHR in terms of functional range of motion and the ability to go back to their pre-injury level of activity. METHODS: This is a retrospective study of 150 patients operated with DMTHR between January 2015 to February 2019 with a minimum follow-up of 12 months. Patients were evaluated clinically using Modified Harris Hip Score (HHS), Range of Motion (ROM), and Patient Reported Outcome Measures (PROM) like ability to squat and sit cross legged. Radiological evaluation was done using radiographs to assess loosening, stress shielding, osteolysis. RESULTS: Mean follow up in our study was 25.2 months (Range 12-46 months). Mean Modified HHS was 71.8 ± 8.11 at 6 weeks post-op and 85.8 ± 7.62 at last follow-up. HHS showed excellent outcome in 36 hips (26.7%), good outcome in 76 hips (56.7%), fair outcome in 20 hips (14.6%), poor outcome in 3 hips (2%). All our patients were allowed to squat and sit cross-legged at a mean follow-up period of 13 weeks (8 weeks-20 weeks) except 10 cases of Revision THR where patients were advised not to squat or sit cross-legged. All patients were able to resume their activities of daily living. CONCLUSION: DMTHR in patients of all ages has shown a good short to midterm clinical outcome which is comparable to conventional THR. It confers the benefit of stability allowing our patients to squat and sit cross legged which is often one of the expectation and requirement of a patient undergoing THR in India. DMTHR in both primary and revision scenarios exhibit a low risk of dislocation, complications and revision surgery.
