This paper reports a rare case of the symptomatic third metatarsal (MT3) - lateral cuneiform (LC) in a 55-year-old male who presented with complaints of severe intermittent pain in his right foot. Plain radiographs and computed tomography scans revealed sclerosis and irregularity at this joint. The intraoperative findings demonstrated a fibrocartilaginous coalition. The pain had improved one year after removing the MT3-LC joint by en bloc and arthrodesis.

Meningioma is relatively common, benign, and extra-axial tumor accounting for about 20% of primary brain and spinal cord tumors. The World Health Organization (WHO) classified these tumors into Grade I (benign), Grade II (atypical), and Grade III (anaplastic) meningioma. Grade I meningioma which is slowly growing tumor and have some rare subtypes. Among them, metaplastic subtype is defined as a tumor containing focal or widespread mesenchymal components including osseous, cartilaginous, lipomatous, myxoid or xanthomatous tissue, singly or in combinations. We report a rare metaplastic meningioma overspreading nearly whole cerebral convexity from main extra-axial tumor bulk in the parietal lobe.

McCune-Albright syndrome (MAS) is a disease with clinical features such as fibrous dysplasia in which normal bone tissue is replaced with abnormal fibrous tissue, abnormalities in the endocrine system, and cafe-au-lait spots on the skin. Although MAS patients are generally known to have reduced bone healing ability, postoperative healing after invasive surgical extraction is still not clearly known due to its relatively rare occurrence. In this report, a 25-year-old female patient, who had been diagnosed with MAS and had a history of abnormal bone healing after fractures of her extremities, underwent surgical extraction of the mandibular third molar with surrounding bone removal. Postoperatively, the patient showed favorable soft tissue and bone healing at the surgical site without abnormal findings such as newly developed fibro-osseous lesions, postoperative infection, or osteomyelitis.

Superficial peroneal nerve (SPN) injuries happen occasionally during surgical treatment of fibular fracture, lateral ankle ligament repair, etc. These injuries are caused because of the variable location of the SPN. It is the injuries are usually treated by steroid injections or anticonvulsants. However, neural symptoms may not respond to treatment and may persist and progress to a painful neuroma. Intractable pain may need surgical treatment. We examined two cases of iatrogenic postoperative SPN injury, and we treated them with transection of the SPN and the intraosseous transposition of the proximal nerve stump using the thrombin-fibrinogen complex with satisfactory outcomes. We report these two cases with a review of the relevant literature.

Fibrous dysplasia (FD) accompanying osteomyelitis (OM) has been reported to result in recurrent, refractory pain and swelling. Although radical resection of the lesions has been suggested, effective surgical treatment strategies have not yet been established due to the limited number of studies on this pathological condition. In this report, we present the conservative surgical management of FD accompanying OM in two patients who exhibited recurrent signs and symptoms. The present report suggests that OM occurring in patients with FD can be successfully managed with conservative surgical treatment and following removal of the odontogenic origin although bone defect in which inflammatory fibro-osseous lesions is removed through decompression surgery may exhibit regeneration of dysplastic bone. In addition, for the prevention of OM in patients with FD, careful clinical examination and thorough management of dental-related pathologies are necessary with regular follow-up examinations to screen for the possibility of malignant changes.

Atlanto-occipital assimilation is an osseous embryological anomaly of the craniovertebral junction in which the atlas (C1) is fused to the occiput of skull. Embryologically, this assimilation may happen due to failure of the segmentation and separation of the caudal occipital and the cranial cervical sclerotome. The segmentation clock is maintained by NOTCH and WNT signalling pathways along with Hox genes and retinoic acid. This condition is likely to be a consequence of mutation in above mentioned genes. The knowledge of this assimilation may be crucial for the clinicians as it may lead to various neurovascular symptoms. The present case report involves the analysis of atlanto-occipital assimilation with its clinical significance and embryological basis.

This is a unique case of metastatic pheochromocytoma of the cervical spine treated with preoperative embolization and subsequent en bloc resection. A 65-year-old man with metastatic pheochromocytoma presented with two weeks of worsening neck pain, left arm and leg weakness and paresthesia, and urinary incontinence. Magnetic resonance imaging showed a metastatic osseous lesion at C6 with severe stenosis and spinal cord compression. The patient underwent successful preoperative angiographic embolization with a liquid embolic agent followed by C5-C7 laminectomy, en bloc tumor resection, and C3-T2 posterior spinal fusion. Six weeks postoperatively, the patient reported improving strength and resolving neck pain and paresthesias. While there is no standard paradigm for the treatment of metastatic pheochromocytomas of the cervical spine, preoperative embolization may minimize intraoperative blood loss and hemodynamic instability during subsequent surgical resection.

Purpose Surgical correction of various occular problems which do not have visual problem in plastic surgical area is to normalize the appearance of the face by restoring the normal position of orbit and eyeball. With development of surgical technique, the orbit can be restored exactly in trauma patient and can be moved totally in hypertelorism, as an example of congenital disease. All these surgeries are based on the hypothesis that the position of oclular glove moves in the plane in a quantitatively predictable reationship to osseous orbit movement. However, no studies have critically evaluated between the change of periorbital soft tissue and the outcome of the surgical correction, because there is no method of objective, quantitave evaluation of the periorbital soft tissue. Method Author suggest the methodology for quantitative assessment of ocular and periocular fat changes using the manipulation of digital images of computed tomographic scan. Results The method was allowed to evaluate inter-dacryon distance, inter-centroid distance, movement of the medial orbital wall, movement of the lateral orbital wall, alteration of thickness of the lateral periorbital fat as indicator of movement of the orbital wall and orbit in the patient with congenital periorbital anomaly and postoperative periorbital surgery. The goal of surgical correction of various occular problems which do not have visual problem in plastic surgical area is to normalize the appearance of the face by restoring the normal position of orbit and eyeball. With development of surgical technique, the orbit can be restored exactly in trauma patient and can be moved totally in hypertelorism, as an example of congenital disease. All these sugeries are based on the hypothesis that the position of oclular glove moves in the plane in a quantitatively predictable relationship to osseous orbit movement. However, no studies have critically evaluated between the change of periorbital soft tissue and the outcome of the surgical correction, because there is no method of objective, quantitave evaluation of the periorbital soft tissue. In this report, author suggest the methodology for quantitative assessment of ocular and periocular fat changes using the manipulation of digital images of computed tomographic scan. Conclusion The method suggested is objective and accurate method in measurement of the orbital contents. It takes time and is not easy to do, however, this kind of measurement for fine structures will be more easily available in near future.

골재생유도술에 의한 골재생과정의 생물학적 현상을 보다 구체적으로 이해하고자, 백서의 대퇴골에 인위적인 골결손부를 형성하고 비흡수성 차폐막을 설치한 다음 골재생유도 과정에서의 미세혈관의 구축 양상을 통상적인 광학 현미경적 소견 및 미세혈관주형 표본 관찰법을 중심으로 관찰한바 다음과 같은 결과를 얻었다. 광학 현미경적 소견의 초기 즉 술후 1주 및 2주 소견상 차폐막에 의해 피개된 실험부에서 보다 정연한 골성회복이 이루어졌으며, 이는 차폐막으로 인한 혈관망 형성의 양상에 의해 영향을 받는 것으로 나타났다. 즉, 차폐막에 의한 연조직 침입이 차단됨으로 인해 인접 골조직으로부터 수평적으로 들어온 혈관에 의해 규칙적인 혈관 분포를 나타내나, 대조군의 경우 연조직에서 유입된 혈관망에 의해 불규칙한 혈관망을 나타내었다. 시간이 경과되면서 재생된 결손부의 골은 재구성되면서 대조군과 실험군 사이에 골성회복의 양상은 유사하였으나, 인접 실험군의 골조직으로부터 유입된 혈관에 의해 형성된 규칙적인 혈관망이 연조직으로부터 침입한 혈관에 의해 그 규칙적인 배열이 흐트러진 대조군에 비하여 골성회복의 속도가 빨라진다는 사실을 확인하였다. 이상의 결과는 차폐막에 의한 골재생 유도과정에서 혈관의 유래와 혈관망의 정렬상태가 골성회복의 속도와 밀접한 관련이 있음을 보여주는 것이다.
