Direct lateral lumbar interbody fusion (DLIF) has been introduced as an effective new thoracolumbar fusion technique for patients with degenerative lumbar diseases. DLIF associated with easy-to-learn, high fusion rate, improved restoration of spinal alignment, and early patient mobilization due to minimally invasive nature. However, ipsilateral L2–L5 nerve root irritation and injury are well-known complications. However, damage to the contralateral nerve root has been rarely reported and, to the best of our knowledge, there have not been any reports about contralateral nerve root injury after DLIF in Korea. Thus, we report a case of contralateral nerve root compression due to osteophyte from the lower endplate of the vertebral body and position of intervertebral cage after DLIF.

PURPOSE: The purpose of this study is to compare radiographic techniques for the diagnostic accuracy in the detection of osteophytes of the mandibular condyle. MATERIAL AND METHODS: A series of bone chips were placed at four locations on the condylar head of a dried human skull. Eight radiographic techniques such as panoramic, transcranial, infracranial, transorbital, reverse-Towne's, submentovertex, multidirectional tomographic and computed tomographic techniques were compared. Three oral radiologists were asked to rate the lesions by four stage score. The statistical analysis was performed by ANOVA test. RESULTS: For the detection of lateral osteophyte, transcranial, infracranial, transorbital and reverse-Towne's views showed superiority. Also, transcranial and infracranial views showed superiority for medial osteophyte. While for the detection of superior and anterior osteophyte, panoramic, transcranial, infracranial, transorbital views showed superiority. Lateral tomograph showed superiority for the detection of superior and anterior osteophyte, but it showed inferiority for lateral and medial osteophte. And antero-posterior tomograph showed superiority for the detection of all osteophytes. Axial computed tomograph showed superiority for the detection of all osteophytes, and coronal computed tomograph showed superiority for lateral, medial and superior osteophytes. While reconstructed sagittal computed tomograph showed relatively superiority for the detection of anterior and superior osteophytes. CONCLUSION: The conventional radiographs can be used for the detection of bony changes of the mandibular condyle, and tomograph or computed tomograph can be used additionally when it is difficult to detect bony changes on conventional radiographs.

Although flexor tendon triggering due to stenosing flexor tenosynovitis is common clinically, extensor triggering is quite rare. Known common causes are impingement between extensor tendon and extensor retinaculum, stenosis of the tendon sheath, and impingement between extensor tendon and osteophyte. We report rare case of triggering in the little finger caused by impingement between extensor digiti minimi and synovial septum.

OBJECTIVE: Various procedures have been introduced for anterior interbody fusion in degenerative cervical disc disease including plate systems with autologous iliac bone, carbon cages, and cylindrical cages. However, except for plate systems, the long-term results of other methods have not been established. In the present study, we evaluated radiologic findings for cylindrical cervical cages over long-term follow up periods. METHODS: During 4 year period, radiologic findings of 138 patients who underwent anterior cervical fusion with cylindrical cage were evaluated at 6, 12, 24, and 36 postoperative months using plain radiographs. We investigated subsidence, osteophyte formation (anterior and posterior margin), cage direction change, kyphotic angle, and bone fusion on each radiograph. RESULTS: Among the 138 patients, a minimum of 36 month follow-up was achieved in 99 patients (mean follow-up : 38.61 months) with 115 levels. Mean disc height was 7.32 mm for preoperative evaluations, 9.00 for immediate postoperative evaluations, and 4.87 more than 36 months after surgery. Osteophytes were observed in 107 levels (93%) of the anterior portion and 48 levels (41%) of the posterior margin. The mean kyphotic angle was 9.87degrees in 35 levels showing cage directional change. There were several significant findings : 1) related subsidence [T-score (p=0.039) and anterior osteophyte (p=0.009)], 2) accompanying posterior osteophyte and outcome (p=0.05). CONCLUSION: Cage subsidence and osteophyte formation were radiologically observed in most cases. Low T-scores may have led to subsidence and kyphosis during bone fusion although severe neurologic aggravation was not found, and therefore cylindrical cages should be used in selected cases.

Spinal stenosis most commonly occurs on lumbar vertebrae because of degenerative changes. This research studied the characteristics of osteophyte development in lumbar vertebrae foramina and association of osteophyte development with lumbar spinal stenosis. The total number of all levels of lumbar spines of subjects was 179 from 31 to 90 years of age. The vertebral foramen was divided into six zones. The prevalence and measurements of the length of osteophytes in the vertebral foramina were obtained. The prevalence and length of osteophytes in the posterior body zone were higher than the laminal zone, and higher than the pedicular zone, respectively. In each zone, the highest prevalence of osteophytes was at L5, except for the inferior posterior body zone that the highest prevalence is at L4. The length of osteophyte was also in same direction as the prevalence. The prevalence of osteophytes among six zones of each level were compared, and found, in L1 to L4, the inferior posterior body zone generally had the highest prevalence, except in L5, the superior posterior body zone had the highest prevalence. Moreover, prevalence, as well as length, of osteophytes in lumbar vertebral foramina, of all levels, was positively associated with age. Vertebral osteophytes can develop beginning at 31 years of age. In conclusion, posterior body of L4 and L5 had the highest prevalence of osteophyte formation, thus, these area had the highest probability to cause spinal stenosis.

The incidence of arthritis in the ankle is relatively low compared to other joints. On the other hand, it receives a lot of pressure per unit area, is vulnerable to damage, and arthritis can arise after trauma. Early ankle arthritis can be considered a case of osteophyte subchondral sclerosis without narrowing of the joint space. Conservative treatment, such as weight control, insole use, drug use, and injection therapy for early ankle arthritis, is effective and can be considered before surgical treatment. Nevertheless, if pain is persistent, surgical treatment to remove bony spurs is effective. Ensuring that there is no other cause of pain when deciding whether to perform an operation is very important.

Small osteophytes are frequently encountered in the foot and ankle, and not to be confused with true osteochondromas, which are relatively uncommon in this region. Osteochondromas are the most common benign osseous neoplasm, occurs in the metaphysis of the long bone. It is rarely found in bones of the foot. Treatment of the osteochondroma is usually conservative, unless symptoms usually pain, are progressive rapid growth, and malignant transformation is suspected. We experienced a rare case of hallux rigidus with osteochondroma of the hallucal proximal phalanx which cause pain and corn of the plantar.

A 63-year-old woman had pronounced pincer nail of her big toenails. Her nail condition was markedly painful and associated with the underlying osteophyte. Under digital anaesthesia the nail plate was completely avulsed and the lateral portions of the matrix were destroyed by electrodessication. Then a longitudinal incision of the distal nail bed was made to separate it from the underlying structure and to expose the osteophyte. The exposed osteophyte was removed and the nail bed was sutured. Tie-under sutures were used to hold the bed in the appropriate transverse curvature. With this surgical correction, the treated nail showed a normal shape at 18 months of follow-up.

PURPOSE: To evaluate the diagnostic accuracy of transcranial radiographs and magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) in the assessment of osseous changes of the condylar head and articular eminence. MATERIALS AND METHODS: Osseous changes of the TMJ were evaluated in forty-three patients. Osseous changes of the condylar head and articular eminence were observed in 41 joints and 64 joints, respectively on transcranial radiographs, and 48 joints and 59 joints, respectively on MRI. RESULTS: The flattening, sclerosis, erosion, and osteophyte formation of the condylar heads were observed in 36.6%, 43.9%, 12.2%, and 7.3%, respectively on transcranial radiographs compared with 35.4%, 20.8%, 37.5%, and 6.3%, respectively on MRI. While, the flattening, sclerosis, and erosion of the articular eminences were observed in 26.6%, 67.2%, and 6.2%, respectively on transcranial radiographs compared with 32.2%, 59.3%, and 8.5%, respectively on MRI. CONCLUSION: There were no statistical differences between transcranial radiographs and MRI scans in the detection of osseous changes of the TMJ. However, MRI scans were superior to the transcranial radiographs in the detection of erosion of the condylar head (p<0.01).
