Purpose: We studied the incidence rate and patterns of bony contusions of the knees with isolated traumatic meniscal tears. Materials and Methods: We analyzed retrospectively MRI scans and medical records of forty-two patients(42 knees) which had undergone operations for isolated traumatic meniscal tears. Mean age, 33.7 years, the number of patients with lateral, medial or both meniscal tears were 19, 18 and 5, respectively. Bony contusions were examined according to incidence, Location, and in relation to the types of meniscal tears. Results: Bony contusion was identified in 5 cases (11.9%) which had medial meniscal tear (4 cases0 or both meniscal tear (1 case). It was always located on the medial compartment of the joint. Bony contusion was found in the knee with various type of traumatic meniscal tears. Conclusion: Bony contusions in thd knees with isolated traumatic meniscal tear have very low incidence and they seem to disappear at or less than 12 months after the trauma. The bony contusions are mainly related to medial meniscal tear and located in the medial compartment of the joint.

Purpose: Multiple rib fracture (MRF) and a hemopneumothorax accompany with most blunt chest traumas. We aimed to analyze the factors increasing the probability of a hemopneumothorax. In addition, other injuries accompanying MRF were analyzed. Methods: We retrospectively reviewed the medical records of 154 mutiple rib fracture patients who visited our hospital between January 2005 and December 2007. The medical records were reviewed for sex, age, mechanism of injury, location, number of fractures, distance of dislocated rib fragments, and presence of complications. We measured the distance of bony dislocations by using the PACS (Picture Archiving and Communication System). Results: The average number of rib fractures was $3.7{\pm}2.1$, and the number of rib fractures significantly influenced the incidence of a hemothorax (p<0.001). The risk of a hemothorax was increased in a bilateral MRF compared to a unilateral MRF (p=0.027). The distance of dislocated rib fragments influenced the probability of a hemothorax significantly (p=0.018), and subcutaneous emphysema and lung contusion were significantly associated with a pneumothorax (p=0.021, p=0.036). Conclusion: The number of MRFs did not influence the risk for a pneumothorax, but did influence the risk for a hemothorax. The laterality, distance of dislocation, also had an influence on the risk for a hemothorax. Also, subcutaneous emphysema and lung contusion were increased in cases with a pneumothorax. We must consider the possibility of a hemothorax even when the initial chest X-ray shows no evidence of a hemothorax. If a lung contusion is present, then an occult pneumothorax must be considered.

Objective : The authors report the microsurgical anterolateral tunnel approach for the treatment of the cervical disc diseases and its postoperative surgical results. Methods : All surgical procedures followed the method of classical microsurgical anterior discectomy. Small tunnel(7-8mm) was made on the disc space reaching to the posterior longitudinal ligament. The disc materials and bony spurs were removed through this tunnel. Thirty-one patients of cervical disc herniation(24 cases with pure disc herniation, 7 cases with combined cervical spondylosis) were evaluated on the symptoms, conformation in plain X-ray, C-T, and MRI. The follow up time was over 2 years. Results : Postoperatively the result(following the out come scale) was excellent and good in Twenty-nine patients. One with fair result showed remnant disc particle and spur and another one is combined with cord contusion. One patient with lesion in C 3-4 space and two cervicothoracic junction showed excellent result. Two patients with osteoporosis also showed good results. Cervical spine curvature and disc space height were not changed on the plain X-ray and MRI in all patients. Twenty-nine patients were discharged within 3 days after surgery without any postoperative complications. Conclusions : The microsurgical anterolateral tunnel approach could be indicated for the treatment of patients with cervical disc diseases and with difficulty in achieving interbody fusion(the higher cervical level and cervicothoracic junction, osteoporosis etc.).
