Arthroscopic removal of a solitary osteochondroma interfering with the podotrochlear apparatus in a foal.

ABSTRACT:

Objective

To report the diagnostics, surgical treatment, and outcome of a juvenile foal with solitary osteochondroma (SO) interfering with the podotrochlear apparatus.

Study design

Case report ANIMAL: One 36-day-old Arabian colt.

Methods

Clinical, radiographic, ultrasonographic, computed tomographic, and histopathologic examinations were required to characterize and treat an SO located at the palmar aspect of the diaphysis of the second phalanx of the left forelimb. This SO caused severe distal interphalangeal joint (DIPJ) inflammation, marked interference with the podotrochlear apparatus, and associated lameness.

Results

Despite the small size of the foal's foot, complete resection of the SO was possible via palmar DIPJ arthroscopy by using motorized equipment. Full resolution of the lameness was achieved within 3 months of surgery.

Conclusion

Atypical SO located on the palmar aspect of the second phalanx can cause marked nonseptic inflammation of the DIPJ and interference with the podotrochlear apparatus and should be considered among the differential diagnoses for severe lameness in juvenile foals. Arthroscopic resection of the SO led to an excellent outcome.

Arthroscopic Femoral Osteochondroplasty With Capsular Plication for Osteochondroma of the Femoral Neck.

Project description:Osteochondromas of the femoral neck are a rare but challenging problem because of their distal location, which is difficult to access arthroscopically. Traditional methods of osteochondroma resection used invasive open approaches to manage these lesions. More recently, advances in hip arthroscopy have allowed expanded treatment of extra-articular hip conditions with a minimally invasive approach. Reports have described the use of hip arthroscopy for osteochondroma removal; however, surgical techniques for the procedure have yet to be described. We describe a technique for arthroscopic resection of a femoral neck osteochondroma using an extended capsulotomy and osteochondroplasty with subsequent capsular plication. This technique uses contemporary hip arthroscopic techniques and constitutes a safe and effective approach to addressing this rare intra-articular pathology of the hip.

Regression of a solitary osteochondroma of the distal humerus in a toddler following trauma.

Project description:Osteochondromas are bone exostoses, with the vast majority extending from the metaphyseal region of long bones and are capped by cartilage. A review of the current literature reveals spontaneous regression of osteochondromas is a rarely documented event, with all but two of these recorded events resolving before skeletal maturity and within 6 years of identification. We present a case of trauma-induced resolution of a solitary osteochondroma after less than 3 months in a 15-month-old male, with a review of current literature.

Arthroscopic Screw Removal After Arthroscopic Latarjet Procedure.

Project description:Arthroscopic Latarjet procedure is an efficient and reliable approach for the treatment of shoulder instability. Nevertheless, the screws fixing the bone block may sometimes be responsible for pain and uncomfortable snapping in the shoulder that is triggered during active external rotation. We propose an all-arthroscopic technique for screw removal in cases of complications involving the screws from a Latarjet procedure. The all-arthroscopic screw removal is reliable and efficient. This procedure is indicated in more cases than thought because of the bone block resorption. It permits a revision of the glenohumeral joint in case of persisting pain.

Hereditary multiple exostoses and solitary osteochondroma associated with growth hormone deficiency: to treat or not to treat?

Project description:BackgroundOsteochondroma generally occurs as a single lesion and it is not a heritable disease. When two or more osteochondroma are present, this condition represents a genetic disorder named hereditary multiple exostoses (HME). Growth hormone deficiency (GHD) has rarely been found in HME patients and a few data about growth therapy (GH) therapy effects in development/growth of solitary or multiple exostoses have been reported.Case presentationWe describe the clinical features of 2 patients (one with osteochondroma and one with HME) evaluated before and after GH therapy. In the first patient, the single osteochondroma was noticed after the start of treatment; the other patient showed no evidence of significant increase in size or number of lesions related to GH therapy.ConclusionIt is necessary to investigate GH secretion in patients with osteochondroma or HME and short stature because they could benefit from GH replacement therapy. Moreover, careful clinical and imaging follow-up of exostoses is mandatory.

Solitary Osteochondroma of the Skull Base: A Case Report and Literature Review.

Project description:We report a case of an osteochondroma in the posterior clinoid process that occurred in a 43-year-old man with trochlear nerve palsy. Although the potential preoperative diagnoses based on computed tomography and magnetic resonance imaging included other intracranial tumors such as calcified meningioma, thallium-201 single-photon emission computed tomography effectively differentiated osteochondroma from those possibilities. Via an orbitozygomatic approach, a subtotal resection was achieved with a good relief of symptoms. Twenty-two cases of solitary osteochondromas in the skull base have been reported that have demonstrated little risk of recurrence or malignant transformation. However, surgery for skull base osteochondromas does carry a significant risk with a reported mortality > 10%. Although some previous reports advocate complete resection as the only curative method for skull base osteochondromas, the risks of total resection should be weighed against the chance for recurrence; our review of the literature demonstrated a relatively high mortality and an extremely low incidence of recurrence.

Arthroscopic Radial Head Implant Removal and Resection.

Project description:Displaced radial head fractures are treated with open reduction and internal fixation using implants. Failure of fixation may occur in the presence of comminution and in multifragmentary fractures; open surgical approaches are necessary for removal of the implants and radial head resection. Arthroscopic radial head resection has been described as a minimally invasive and effective treatment for failed radial head fracture fixation; however, periarticular adhesions and prominent implants add to the complexity and technical difficulty of the procedure. The described technique uses 3 portals for adhesiolysis, implant removal, and radial head resection. Resection is performed in stages; smaller-diameter instruments are used to gain and improve access, and larger resectors are used subsequently. Adequacy of resection is assessed arthroscopically and with biplanar imaging. The arthroscopic technique avoids the need for an open surgical approach and prevents subsequent morbidity. In addition, the rehabilitation time is shorter and patient satisfaction is high.

Handheld Osteotomes Facilitate Arthroscopic Elbow Osteophyte Removal.

Project description:Arthroscopic elbow surgery is a challenging procedure in part because of the limited intra-articular volume of the joint, the congruence of the elbow articulation, and the close proximity of the neurovascular structures. Arthritic conditions that result in the development of bony prominences and osteophytes are usually amenable to arthroscopic management and include diagnoses such as osteoarthritis, rheumatoid arthritis, and valgus extension overload syndrome. Safe and efficient removal of these osteophytes can be problematic, however, because of technical difficulties often encountered while using arthroscopic burrs and shavers as well as the risks of inadvertent, iatrogenic injury to adjacent articular cartilage and other structures. A valuable and effective technique using small handheld osteotomes to facilitate the arthroscopic removal of intra-articular osteophytes and other bony prominences is described and shown.

Revision Arthroscopic Greater Tuberosity Fracture Fixation and Implant Removal: An Open to Arthroscopic Approach.

Project description:Failure of a greater tuberosity fracture fixation with screws can lead to stiffness, pain, and weakness of the rotator cuff. Management of a previously performed open greater tuberosity fracture fixation with screws involves implant removal and refixation of the fragment. Doing this arthroscopically in a previously performed open surgery has its own challenges but distinct advantages. Describe herein is a technique for performing this revision surgery arthroscopically.

Robot-assisted laparoscopic removal of an extraperitoneal pelvic solitary fibrous tumor

Project description:Highlights • Pelvic SFTs are rare, typically benign soft tissue neoplasms that pose a diagnostic challenge for gynecologists.• Retroperitoneal pelvic SFTs can mimic gynecologic malignancies and should be considered in diagnosis of a solitary pelvic mass.• Pathologic diagnosis is typically confirmed by immunohistochemistry staining positively for CD34 and STAT6.• Complete surgical excision is recommended for these tumors and can be completed with a minimally invasive approach.• Close long-term follow-up is necessary due to possible recurrence or metastasis, especially for high-risk pathologic features.

Bilateral scapular osteochondroma in Multiple Hereditary Exostosis patient presented with bilateral shoulder pain treated with arthroscopic and open excision: Case report.

Project description:Introduction and importanceMultiple etiologies for snapping shoulder syndrome have been described in the existing literature. Scapular osteochondroma is considered as a rare etiology and bilateral scapular osteochondroma have rarely been reported to date. Patient can present with discomfort, pain and crepitation. Multiple surgical methods were described and the patient underwent two different surgical methods with preferable outcome for arthroscopic side.Case presentation24 year-old male who is known case of Multiple Hereditary Exostosis (MHE) since childhood presented with bilateral shoulder pain and snapping scapula. Computed tomography demonstrated bilateral ventral scapular osteochondromas. One side treated with open excision and other side with arthroscopic excision.Clinical discussionPatient exhibited resolution of symptoms, restoration of function on both sides, but he reported cosmetic preference over arthroscopic side and faster recovery from surgery as well in terms of pain resolution and rehabilitation.ConclusionOsteochondroma should by one of differential diagnoses for snapping shoulder syndrome. Despite arthroscopic excision is technically demanding, it carries better outcome compared to open excision.
