Treatment of open tibial fracture with Ender nail.

BACKGROUND: This retrospective study aims to evaluate the effect of Ender nail in management of open type I and II unstable tibial fractures. METHODS: From 1984 to 1993, 30 cases of open unstable tibial shaft fracture (with fibular fracture) were collected in the retrospective study. All were fixed with Ender nails. The followup period was 99 (24-135) months. RESULTS: The average of blood loss was 140 cc, operation time 45 minutes, hospital day 10 days, and union time 20.5 weeks. Student t-test revealed statistically significant difference between open type I cases and type II cases in some parameters described above. CONCLUSIONS: Ender nail is effective in the treatment of open type I and II unstable tibial shaft fractures, but it should be used carefully, especially in cases with more comminution.

Complications in surgical treatment of undisplaced femoral neck fracture.

BACKGROUND: Percutaneous Knowles' pinning is a well accepted treatment of undisplaced femoral neck fracture, but there are some complications that have seldom been discussed. METHODS: One hundred and eighty two patients with undisplaced femoral neck fractures, at a mean age of 67 years, were treated by percutaneous Knowles' pinning between 1983 to 1989, and followed for an average of 102 months. The clinical results and complications were evaluated. The data were collected on the basis of age and bone density. Student's t-test was used to evaluate the significance of the results. RESULTS: The mean union time was 20 weeks. In all the patients, 85.8% had good results, 3.8% patients had acceptable results and 10.4% patients had poor results. Old age (> or = 65 years) and osteoporosis (Singh index < or = 3) were two factors of the poor result. Thirty-two cases (17.6%) developed complications. The incidence of nonunion or implant problems was apparently higher in the older or osteoporosis group, but avascular necrosis of femoral head correlated little with old age or osteoporosis. CONCLUSIONS: Although percutaneous Knowles' pinning is simple, safe, economic and reasonably effective for the treatment of undisplaced femoral neck fractures, we should pay more attention to the uncooperative, old, and osteoporotic patients.

Ender nail in unstable closed tibial fractures.

BACKGROUND: This retrospective study aims to evaluate the effect of Ender nail in management of unstable closed tibial fractures. METHODS: From January 1985 to May 1992, 99 cases of unstable closed tibial shaft fractures (with fibular fractures) were collected for retrospective study. All the 99 tibiae were fixed with Ender nails. The mean follow up period was 80 (26-115 months). RESULTS: The clinical results were evaluated with special charts. The average blood loss was 126 ml. Operation time was 45 minutes. Hospital day was 10.2 days. Union time was 16.8 weeks for Winquist-Hansen (WH) type I-II fractures and 20.5 weeks for VVH type III-V fractures. Student t test revealed statistically significant differences between the clinical results of WH type I-II cases and those of WH type III-V cases. The postoperative complications included superficial infection in 1 case (1%), nail protrusion in 13 (13%), malunion in 10 (10%), aseptic nonunion in 2 (2%) and infected nonunion in 1 (1%) (overall 18% in the 99 cases). CONCLUSIONS: Ender nail is no doubt effective in treatment of less comminuted unstable tibial shaft fractures, but should be used carefully for more comminuted unstable tibial shaft fractures.

Management of avulsion injury of the PCL with reattachment.

Twenty-eight cases of avulsion injury of the posterior cruciate ligament (PCL) treated by reattachment were followed up to evaluate the results. Evaluation was based on appropriate functional and dynamic criteria: the results are classified as good, fair or poor. The interval between injury and repair ranged from 3 days to 2 months with a mean 4 weeks. The follow-up period ranged from 3 to 10 years with a mean of 5 years. The evaluation revealed 27 (96 per cent) good, one (4 per cent) fair and no poor results. It is apparent that operative reattachment is the treatment of choice for avulsion injury of the PCL, especially in early cases.

Surgery for old ankle fracture. 13 cases followed for 9 (5-15) years.

Between 1978 and 1988, we treated 13 cases of neglected ankle fractures by open reduction and internal fixation or osteotomy 11 (2-36) months after the accident. Having been followed for 9 (5-15) years, the results were evaluated. All the patients were improved, even though restoration of the anatomy of the joint often was difficult. Those operated on after less than 6 months had better function than those with longer delays.

Delayed treatment of ankle fracture.

BACKGROUND: Cases of old ankle fractures with different delayed treatments in different conditions were collected and evaluated to determine which treatments were optimal for individual type of fractures. METHODS: Sixteen cases of old ankle fractures were managed by open reduction and internal fixation, osteotomy, or removal of loose fragment according to the condition of the fractures between 1977 and 1987. The follow-up period was from 5 to 15 years with mean 7.9 years. The final result was evaluated by a modified performance index. RESULTS: All the 12 patients treated with open reduction and internal fixation for malposition got improved with the mean performance score rising from 37 before operation to 76 after operation. Improvement was also noted in all the 3 patients treated with osteotomy for malunion without significant arthritis, rising from 44 to 88. One patient had painful non-united fragment of medial malleolus, and removal of the loose fragment was done to improve the score from 58 to 96. CONCLUSIONS: Management of old ankle fractures can be effective and beneficial when appropriate treatments are given according to the different conditions of the fracture and joint.

Management of insufficiency of posterior cruciate ligaments.

BACKGROUND: This study aims to evaluate the role of different methods in management of insufficiency of posterior cruciate ligament (PCL) that were used in VGH-Taipei. METHODS: 129 cases with insufficiency of PCL were collected to evaluate, according to functional and dynamic criteria, the results of different managements which were graded as good, fair, or poor. The patients were divided into 3 groups, i.e. group 1 with conservative rehabilitation therapy, group II with surgical reattachment, and group III with surgical ligament reconstruction that had 3 subgroups including IIIa reconstruction with medial head of gastrocnemius, IIIb with patellar tendon and IIIc with artificial ligament. The artificial ligaments used were Leeds-Keio ligament (group IIIcl), Dacron ligament (group IIIc2) and Goretex ligament (group IIIc3). The duration from injury to treatment varied from 3 days to 12 years with mean 45 weeks. The followup period was from 38 months to 112 months with mean 62 months. RESULTS: The results revealed 6 cases of good grade (25%) and 18 cases of fair grade (75%) in group 1, 20 cases of good grade (95%) and 1 case of fair grade (5%) in group II, 14 cases of good grade (40%), 10 cases of fair grade (29%) and 11 cases of poor grade (31%) in group IIIa, 3 cases of good grade (100%) in group IIIb, 13 cases of good grade (82%) and 3 cases of fair grade (18%) in group IIIcl, 19 cases of good grade (83%), 3 cases of fair grade (12%) and 1 case of poor grade (4%) in group IIIc2, and 3 cases of good grade (43%), 3 cases of fair grade (43%), and 1 case of poor grade (14%) in group IIIc3. CONCLUSIONS: Conservative intervention could be satisfactory in some cases with PCL insufficiency, especially in cases with isolated PCL injury, while surgical methods is mandatory in the others, especially in cases with chronic symptomatic PCL insufficiency.

Bateman bipolar hemiarthroplasty for displaced intracapsular femoral neck fractures. Uncemented versus cemented.

Four hundred forty-seven patients with 451 displaced fractures of the femoral neck were treated with Bateman bipolar hemiarthroplasty (190 cemented and 261 uncemented) between 1985 and 1990 in the authors' institution. During a follow-up period of at least two years, the authors found less thigh pain (13% versus 46.2%) and higher Harris hip scores (86 versus 79) in the cemented group in comparison with the uncemented group. Radiographic examination showed less radiolucent zones and subsidence in the cemented group. Heterotopic ossification was more common in the cemented group. Despite the fact that the cemented group had longer operative times (average, 20 minutes) and more blood loss (average, 160 ml) during the operation, there was no significant difference in the early mortality rate observed between these two groups. The cemented prostheses provided better functional and radiographic results and fewer failures in the early stage. In addition, the cemented prostheses did not lead to more complications and higher mortality rates. Thus, for elderly patients who need early ambulation and functional recovery, the cemented Bateman bipolar prosthesis appears to be a better choice than the uncemented Bateman prosthesis.

Multiple glomus tumors: a case report.

Multiple glomus tumor (MGT) is rare in incidence. A 37-year-old male was diagnosed to have localized MGT over his right leg. With the characteristics of unusual location (right lower leg), development in sequence, and distribution along the course of the lateral sural cutaneous nerve. Its pathological findings were also characteristic. When the overall presentations showed in cases with recurrent symptoms and signs of glomus tumor after surgical excision, recurrence and multiplicity should be considered.

Blood glucose rise after lactose tolerance testing in infants.

Lactose tolerance tests are used clinically to screen children and infants. It is assumed that absorption of a lactose challenge in infants would occur in a predictable pattern prior to weaning. Twenty-one infants from 3 to 12 months of age were studied. The maximum blood glucose rise over fasting levels ranged from 11.0 to 62.0 mg/100 ml; the mean was 32.6 mg/100 ml. Six infants had a maximum rise of less than 20 mg/100 ml. Eleven infants (52%) had a maximum rise of greater than 30 mg/100 ml. Signs of intolerance were not noted in any subject. Weight and length were normally disturbed. Results indicate the variance in glucose rise existing within a population of infants growing normally and consuming milk. Gastric emptying, digestion, and absorption may influence the blood glucose rise after a lactose test. Established glucose levels used as an index to lactose absorption in older children and adults may not accurately reflect lactase activity in infants.
