Forty five cases of adult tibial shaft fractures were treated with flexible intramedullary nails under image intensifier at the department of orthopaedic surgery, Capital Armed Forces General Hospital during between April 1986 to July 1988. The results were summarized as follows: 1. 45 cases were all male, the average age was 24.3 years and the most common cause of fractures was sports injury(20 cases) and the second most common cause was traffic accident(18 cases). 2. 11 cases out of 45 cases were open fracture and 34 cases were closed fracture. Eight cases of open fraeture were grade I and three cases were grade II. Twenty eight cases were comminuted fracture. The most common level of the fracture was middle third of the tibial shaft. 3. Average interval from injury to Ender nailing was 13.5 days and the mean duration of permission to full weight bearing was 9.2 weeks. 4. Out of 2 cases of delayed union, the average time of clinical bone union was 9.7 weeks and that of roentgenological bone union was 14 weeks. 5. 11 cases of complication were noted among the 45 cases of tibial shaft fracture which were treated by PGP nailing such as angulation, rotation, ankle joint stiffness, delayed union, shortening, and soft tissue infection. 6. PGP nailing is considered to be a valuable method in treating tibial shaft fracture because of their relative ease of nailing, allowing early weight bearing and decreased complication.

Purpose: Epidemiological data on injuries resulting from ice hockey and their management are lacking in Korea. A comprehensive analysis of such data is crucial for the effective prevention and management of ice hockey injuries. This study aimed to determine the epidemiological profile of ice hockey injuries and their management among elite Korean players. Methods: The descriptive epidemiological study involved three semiprofessional male ice hockey teams and used a retrospective self-reported questionnaire for assessment. The data collected included demographic characteristics such as player positions and stick-side preferences, injured body parts, injury types, treatment methods, and the decision-maker for returning to sports. Results: A total of 68 players were included in the study, of whom 58 (85.3%) experienced moderate-to-severe orthopedic injuries. Among the reported injuries, 93 (77.5%) occurred during the games, with player-to-player contact being the most frequent cause of such injuries. The decision to return to sports in 53 cases (44.2%) was made by the medical staff, whereas players and nonmedical staff made that decision in 67 cases (55.8%). The decision-making process of the medical staff for allowing players to return to sports was significantly associated with the player’s position and whether the injury required surgery. Conclusion The study emphasizes the high prevalence of orthopedic injuries among elite ice hockey players in Korea and the importance of injury prevention strategies. It also highlights the need for increased involvement of medical staff in return-to-play decisions to ensure successful recovery of players and their reintegration into the competition.

Hematogenous spread from tuberculous lesions of other parts of the body represent the origin of intracranial tuberculomas. In most series of the literature, the cerebellum has about two thirds and the cerebral hemispheres about one third of the intracranial tuberculomas. It may occurs as a single lesion, but multiple intracranial tuberculomas varies from 10% to 33% of the cases due to the hematogenous spread. Calcium deposits are rare, occurring in about 6% of cases. Ramamurthi and Varadarajan described the two types of the intracranial tuberculoma; 1. Superficial and vascular type, produces early focal signs of increased intracranial pressure. 2. deep and avascular type, accompanied by signs of increased intracranial pressure. We have been experienced in one case of symmetrical and bilateral cerebellar tuberculomas probably originated from the pulmonary lesion.

The authors reported 100 cases of acute subdural hematomas confirmed by operation from Jan. 1972 to Sept. 1975. We discussed the relationship of the type of operation to mortality in acute subdural hematomas. The types of surgical operations were divided in 4 groups. The surgical mortality rate was 19% for frontotemporoparietal craniotomy, 29% for multiple burr holes technique, 42% for craniectomy and 48% for subtemporal decompression with burr holes and total over-all mortality was 36% in our cases. The authors reviewed the literatures described the surgical operative method and it's mortality and so we thought large frontotemporoparietal craniotomy is more valuable method for operation of the acute subdural hematomas.

BACKGROUND: Recent studies demonstrated that volatile anesthetics suppress the NO-cGMP system in the vascular system. It has been known that the hemodynamic changes produced by volatile anesthetics in septic patients are mediated by upregulation of iNOS leading to excessive release of NO. The mechanisms underlying suppression of the NO-cGMP system by anesthetics are still controversial. It has been elucidated that nitric oxide synthase (NOS) plays a major role in the regulatory function in the L-arginine-NO system. So we examined the effects of NOS inhibitor (L-NAME, aminoguanidine) and NO scavenger (hydroxocobalamin) on vascular smooth muscle contractile function in lipopolysaccharide (LPS)-treated rat aorta during halothane administration. METHODS: Aortic ring preparations were obtained from LPS-treated (1.5 mg/kg, ip, for 18 h) rats. We evaluated the effects of hydroxocobalamin, L-NAME and aminoguanidine on contractile responses to phenylephrine during halothane (1 & 2 MAC) administration respectively. Statistical significances (P<0.05) were analyzed according to data characterictics by repeated measures ANOVA test and student's t-test. RESULTS: The contractile responses to phenylephrine in LPS-treated rats aorta were significantly (P<0.05) increased in the presence of hydroxocobalamin and L-NAME. During the halothane (1 and 2 MAC) administration, the contractile responses to phenylephrine in LPS-treated rats aorta were increased significantly (P<0.05) in the presence of hydroxocobalamin and L-NAME. CONCLUSIONS: From these results, it is suggested that hydroxocobalamin and L-NAME may be useful in the therapy of septic shock.

The authors report a case of bladder fistula associated with a medial thigh cutaneous fistula and chronic osteomyelitis of the pubic bone 11 years after surgery for a pelvic bone fracture and bladder rupture. In the presenting case, despite the clinical suspicion, none of the diagnostic tools demonstrated the bladder fistula preoperatively. This case suggests that bladder repair should be prepared, even if the bladder fistula cannot be confirmed by imaging studies because the amount of urine leakage can be minimal or the fistula can close spontaneously.

BACKGROUND: This study evaluated the shoulder girdle muscle characteristics of elite archery athletes and provides suggestions for archery training programs. METHODS: This study enrolled 15 cases of high level archery athletes (7 males, 8 females) and 30 cases of (15 males, 15 females) sex, age-matched, healthy, non-athletic individuals. We measured peak torques of flexion (FL), extension (EX), abduction (ABD), adduction (ADD), external rotation (ER) and internal rotation (IR) of both shoulders at an angular velocity of 30°/sec, 60°/sec, and 180°/sec. The peak torques and peak torque ratios of FL/EX, ABD/ADD, and ER/IR of the two groups were compared. RESULTS: The archer group had a greater peak torque of IR and ADD, but only in the left shoulder (p < 0.05). In the same group, both shoulders had greater peak torque of EX and lower peak torque of FL. The peak torque ratios of FL/EX of both shoulders were significantly lower in the archer group at all three angular velocities (p < 0.05). The peak torque ratios of ABD/ADD were significantly greater in only the left shoulder of the archer group (p < 0.05). CONCLUSIONS: The prominent characteristics of the shoulder girdle muscles of an elite archer are stronger adductor muscles of the bow shoulder and stronger extensors of both shoulders, as compared to healthy, non-athletic individuals. These muscle groups of the shoulder probably contribute a major role in maintaining the accuracy and stability during archery shooting. Hence, a training program that selectively enhances the adductor and extensor muscles could prove helpful in enhancing the archery skills of the athlete.

Purpose: To evaluate the clinical and radiographic results of primary bipolar arthroplasty during average 9.8-year period, using a non-cemented Multilock femoral stem and a biarticular acetabular cup. Materials and Methods: This study included 24 patients (29 hips) who underwent primary bipolar hemiarthroplasties with Multilock femoral stems and biarticular cups and who could be followed for more than seven years. Clinically, we evaluated the Harris Hip scores and patient complaints of thigh and inguinal pain. We also evaluated the radiographic measurements around the femoral stems and the bipolar cups. Results: The average Harris Hip score improved from 57.4 points to 91.6 points; and 3 (10.3%) hips were associated with thigh pain and 4 (13.8%) hips with inguinal pain. Around the femoral stem there was a non-progressive radiolucent line less than 1 mm in length in 4 (13.8%) hips and osteolysis was present in 6 (20.6%) hips. With respect to the stability of the fixations, there was osseous ingrowth in 26 (89.7%) hips and fibrous ingrowth in 3 (10.3%) hips. Around the acetabulum there was osteolysis in 5 (17.2%) hips, proximal migration of the cup in 2 (6.9%) hips, and erosion of the acetabular cartilage in 10 (34.5%) hips. There were 3 (10.3%) biarticular cups, which were converted to total hip arthroplasties, but no femoral stems were revised. The overall failure rate of the primary operations was 10.3%. Conclusion: The current study demonstrated favorable results after bipolar hemiarthroplasties with Multilock femoral stems. However, the osteolysis that occurred around the femoral stems and the acetabula emerged as a problem after the total hip arthroplasties. In particular, it is expected that the osteolysis would increase over time and become the main cause for the need for surgical revision.
