An 11-month-old, 5.6 kg, grade 4 on a 5-point scale body condition score, castrated male Korean short hair cat was presented with right hindlimb lameness for 3 days without trauma. On physical examination, severe pain with crepitation was elicited at the hip region but not at the stifle. Radiographic examination and computed tomography revealed a Salter-Harris type 1 fracture of the femoral capital physis and dysplasia of the proximal tibial epiphysis. Spontaneous femoral capital physeal fracture was suspected and femoral head and neck osteotomy was performed. Treatment for proximal tibial dysplasia was not performed. On histopathologic examination of femoral head, a cluster of chondrocytes in a proliferative zone at the epiphyseal plate was observed. Therefore, spontaneous femoral capital physeal fracture was diagnosed. The patient recovered his gait, and no related clinical signs were observed during 6 months of follow-up.

Traumatic injuries of the face often involve root fractures especially in anterior teeth. The prognosis and the treatment of the root fracture depend on the extent of the fracture line, general health and patient compliance. This case report outlines a new conservative trial treatment modality to stabilize the maxillary central incisors with horizontal root fracture on the cervical to middle third by fabricating canine guidance to remove loading on the traumatized maxillary central incisors during eccentric movements and thus inducing spontaneous healing of the fractured line between the fragments. Radiographs after thirty months showed adequate healing with no signs of pathological changes including root resorption, ankylosis or displacement. Long term follow-up revealed that vitality, stability and aesthetics were maintained and the patient was satisfied with the outcome.

Clavicular hook plate is known to be an effective treatment on acromioclavicular (AC) joint injury, but there have been some reports of complications, like osteolysis and bony erosion of the undersurface of acromion. Fifty-five year old male underwent open reduction and hook plate insertion on Rockwood type 5 acromioclavicular joint dislocation. He complained of protrusion of posterior acromion at 1 month after the surgery, and acromial fracture was noted in simple radiographs. The hook plate was removed and any other treatment for osteosynthesis was refused by the patient. At the 18 months after the surgery, the patient had no pain and a full range of motion with no tenderness around the shoulder joint. After two years, plain radiographs revealed complete bony union of the acromion fracture.

There have been many treatment methods for traumatic subgingival crown fracture and intrusion without spontaneous eruption. The orthodontic forced eruption generally results in favorable clinical findings than crown lengthening with osteotomy and intentional replantation. In first two cases with subgingival crown fracture due to trauma, authors applied orthodontic forced eruption with axed appliance after root canal therapy and then restored them with composite resin. In another case with traumatic intrusive luxation, we observed spontaneous eruption of the corresponding tooth for about 6 months and then returning it to normal position by forced eruption with removable appliance, but root canal filling was conducted after apexification due to devitalization during forced eruption, and so clinically favorable results were obtained.

Background: A hip fracture may occur spontaneously prior to the hip impact, due to the muscle pulling force exceeding the strength of the femur. Objects: We conducted falling experiments with humans to measure the activity of the hip muscles, and to examine how this was affected by the fall type. Methods: Eighteen individuals fell and landed sideways on a mat, by mimicking video-captured real-life older adults' falls. Falling trials were acquired with three fall directions: forward, backward, or sideways, and with three knee positions at the time of hip impact, where the landing side knee was free of constraint, or contacted the mat or the contralateral knee. During falls, the activities of the iliopsoas (Ilio), gluteus medius (Gmed), gluteus maximus (Gmax) and adductor longus (ADDL) muscles were recorded. Outcome variables included the time to onset, activity at the time of hip impact, and timing of the peak activity with respect to the time of hip impact. Results: For Ilio, Gmed, Gmax, and ADDL, respectively, EMG onset averaged 292, 304, 350, and 248 ms after fall initiation. Timing of the peak activity averaged 106, 96, 84, and 180 ms prior to the hip impact, and activity at the time of hip impact averaged 72.3, 45.2, 64.3, and 63.4% of the peak activity. Furthermore, the outcome variables were associated with fall direction and/or knee position in all but the iliopsoas muscle. Conclusion: Our results provide insights on the hip muscle activation during a fall, which may help to understand the potential injury mechanism of the spontaneous hip fracture.

Spontaneous osteonecrosis of the knee was first described by Ahlbck et al in 1968 as the spontaneous and sudden onset of severe pain, usually on the medial side of the knee joint, in old age(>60 years) with no specific etiologic factors. They differentiate the disease from osteochondritis dissecans, osteoarthritis, fracture, infection, neuropathic joint and secondary osteonecrosis of the knee joint. So far many investigators described this disease but had never observed cases developed in young patient with familial occurrence. The report presented here is a case of spontaneous osteonecrosis of both medial and lateral femoral condyles involving the bilateral knee joint that were treated by arthorscopic loose body removal and multiple drilling.

We experienced a case of primary sternal tuberculosis with destroyed midsternum and bony defect. An 22-year-old female was admitted to our hospital two times for severe sternal pain and spontaneous fracture without history of trauma. On hospital admission, chest X-ray and chest CT showed destruction of midsternum and soft tissue swelling. Fine needle aspiration cytology revealed tuberculous osteomyelitis with cold abscess. And the patient was treated with usual anti-tubeculosis medication for preoperative preparation. At operation, we confirmed midsternal destruction with cold abscess and multiple sinus tracts. After removal of diseased sternal segment and cold abscess, we performed sternal reconstruction with autologus iliac bone graft. The pathologic report was compatible with tuberculous osteomyelitis and caseous necrosis The postoperative course was smooth and uneventful, and she remains well without sternal instability two months later.

Vertebral compression fractures result in vertebral height loss and alter sagittal spinal alignment, which in turn can lead to increased morbidity and mortality. Acute osteoporotic vertebral compression fractures are known to increase mobility and instability of the spine. There are limited published data correlating the degree of dynamic mobility and the efficacy of kyphoplasty on vertebral compression fractures. Here we report a 73-year-old female with a severe acute osteoporotic L2 compression fracture who obtained total vertebral height restoration following kyphoplasty, with resolution of back pain.

For the purpose of evaluation of clinical characteristics in multiple rib fracture due to accident , 24 cases treated by surgical rib fixation using Judet`s strut for multiple rib fracture and flail chestduring the period from June 1993 to October 1994 were reviewed. There were 17 males and 7 females.They ranged in age from 19 years old to 56 years old. The causes of rib fracture were traffic accident in 18 cases, fall down in 3 cases, compression in 2 cases stab wound in 1 case. The number of rib fracture were five in 7 cases, six in 5 cases, four in 5 cases, three in 3 cases. Associated intrathoracic injuries were hemopneumothorax in 12 cases, hemothorax in 10 cases, lung laceration or hemorrhagic contusion in 7 cases. Associated extrathoracic injuries were abdominal injuries in 21 cases, orthopedic problem in 7 cases, head trauma in 4 cases. The most common fractured site was posterolateral portion of the ribs. The causes for operation were flail chest, severe rib displacement and pain, hemothorax or hemopneumothorax with continuous air leakage and stab wound. There were 6 postoperative complications ; one with hydrothorax, two with fibrothorax, two with wound infection and one case of death due to multiful organ failure. Postoperatively, all patients became comfortable and complained less painful. Twenty patients restored spontaneous breathing without ventilator support, three patients were ventilated during a day and one patient expired after 2 days. There were no morbidity and mortality related to operation.

Alloplastic materials used for orbital fracture reconstruction can induce complications, such as infection, migration, extrusion, intraorbital hemorrhage, and residual diplopia. Silicone is one of the alloplastic materials that has been widely used for decades. The author reports a rare case of spontaneous extrusion of a silicone implant that was used for orbital fracture reconstruction 30 years earlier. A 50-year-old man was admitted to the emergency room for an exposed substance in the lower eyelid area of the left eye, which began as a palpable hard nodule a week earlier. The exposed material was considered to be implant used for previous surgery. Under general anesthesia, the implant and parts of the fibrous capsule tissue were removed. Several factors hinder the diagnosis of implant extrusions that occur a long period after the surgery. So, surgeons must be aware that complications with implants can still arise several decades following orbital fracture reconstruction, even without specific causes.
