Fractures of the lateral process of the talus: two case reports and a comprehensive literature review

Fractures of the lateral process of the talus are frequently overlooked and should be considered in the differential diagnosis of patients with acute and chronic ankle pain. Early diagnosis is emphasized in all series reviewed in the literature to prevent long-term complications. Thorough radiographic evaluation is necessary to determine the need for operative vs. nonoperative management. Small nondisplaced fractures are treated with cast immobilization, whereas large or displaced fractures usually require open reduction and internal fixation. Comminution of fragments may necessitate surgical excision. To achieve the best possible results, a timely diagnosis is required, and it is our belief that early treatment has better overall results.     

Assessment and management of three-and four-part proximal humeral fractures

Three-and four-part comminuted fractures of the proximal humerus are difficult and technically demanding to treat. The various treatment methods reported in the literature are reviewed. It is recommended that three-part fractures be treated with open reduction and internal fixation. Four-part fractures in the younger, active patient also can be treated successfully with open reduction and internal fixation. However, in the elderly and in the patient with osteoporosis, a hemiarthroplasty is the treatment of choice. There is a need for universal agreement on a scoring system for measuring outcome in these fractures to allow a meaningful comparison between reported treatment methods.     

Substrate specificity of ascidian sperm trypsin-like proteases, spermosin and acrosin

We retrospectively reviewed the office records of the senior author--which include two national ballet companies--and identified 35 dancers who sustained distal shaft fractures of the fifth metatarsal. The usual fracture pattern is a spiral, oblique fracture starting distal-lateral and running proximal-medial. Treatment consisted of open reduction and internal fixation for 2 patients, closed reduction and percutaneus fixation for 2 patients, short leg weightbearing cast for 7 patients, and an elastic wrap and treatment of symptoms for 24 patients. Patients with marked displacement of the fracture underwent internal fixation early in the study period; but more recent treatment emphasized nonoperative means, even for displaced fractures. The average time to pain free walking was 6.1 weeks (range, 0 to 16); return to barre exercises, 11.6 weeks (range, 4 to 48); and return to performance, 19 weeks (range, 6 to 52). There was one delayed union (7 months) and one refracture (2 months) that subsequently healed. All patients returned to professional performance without limitation and no patient reported pain with performance at followup. Spiral fractures of the distal shaft of the fifth metatarsal are common injuries and can usually be treated nonoperatively for these high performance athletes without long-term functional sequelae.     

Small wire external fixation of high energy tibial plateau fractures

Open plate osteosynthesis for high energy tibial plateau fractures with dissociation between the metaphysis and diaphysis has been plagued with frequent soft tissue complications. The Harbor-University of California at Los Angeles Medical Center's experience with small wire external fixation supplemented by limited internal fixation is examined. This alternative method of adequate stable fixation offers the advantage of minimal soft tissue compromise. Twenty-four patients with Schatzker Type VI tibial fractures were treated with small wire external fixation. Supplementary limited internal fixation was used with percutaneous screws in 10 patients and with open reduction in one patient. Sixteen patients had isolated fractures, and eight others suffered multiple injuries. Minimum followup was 12 months. All fractures healed. Complications included one septic knee, two infections at screw sites, and one 10 degrees knee flexion contracture. One knee had Grade 3 radiographic arthrosis, five had Grade 2, 10 had Grade 1, and eight showed no arthrosis. The outcomes (Knee Society clinical rating system) of this study compare favorably with outcomes described in reports published previously for this type of fracture, despite inclusion of eight multiply injured patients. This technique preserves the goals of early range of motion and stable fixation for these devastating injuries, while decreasing the observed major wound complications and nonunion rates. However, longer followup may reveal higher arthrosis rates, specifically in those fractures that were not anatomically reduced.     

Operative treatment of fractures of the tibial plafond. A randomized, prospective study

We performed a randomized, prospective study to compare the results of two methods for the operative fixation of fractures of the tibial plafond. Surgeons were assigned to a group on the basis of the operation that they preferred (randomized-surgeon design). In the first group, which consisted of eighteen patients, open reduction and internal fixation of both the tibia and the fibula was performed through two separate incisions. An additional patient, who had an intact fibula, had fixation of the tibia only through an anteromedial incision. The second group consisted of twenty patients who were managed with external fixation with or without limited internal fixation (a fibular plate or tibial interfragmentary screws). Ten (26 per cent) of the thirty-nine fractures were open, and seventeen (44 per cent) were type III according to the classification of Rüedi and Allg?wer. There were fifteen operative complications in seven patients who had been managed with open reduction and internal fixation and four complications in four patients who had been managed with external fixation. All but four of the complications were infection or dehiscence of the wound that had developed within four months after the initial operation. The complications after open reduction and internal fixation tended to be more severe, and amputation was eventually done in three patients in this group. At a minimum of two years postoperatively (average, thirty-nine months; range, twenty-five to fifty-one months), the average clinical score was lower for the patients who had had a type-II or III fracture, regardless of the type of treatment. With the numbers available, no significant difference was found between the average clinical scores for the two groups. All of the patients, in both groups, who had had a type-II or III fracture had some degree of osteoarthrosis on plain radiographs at the time of the latest follow-up. With the numbers available, there was no significant difference between the two groups with regard to the osteoarthrotic changes. We concluded that external fixation is a satisfactory method of treatment for fractures of the tibial plafond and is associated with fewer complications than internal fixation.     

Using pulsatile pressure saline/antibiotic irrigation before reduction and fixation of infected mandibular fractures: literature review and report of two cases

The efficacy of pulsatile pressure saline irrigation has been demonstrated in the orthopedic, surgical, and dental literature. However, its use for treating infected mandibular fractures has not been documented. This article reviews the literature concerning pressure irrigation. The pulsatile pressure saline/antibiotic irrigation technique and indications for its use during the treatment of infected mandibular fractures are demonstrated with two case reports. The pulsatile pressure saline/antibiotic irrigation system is a useful adjunct to the standard therapeutic modalities of infection management. It is also useful for managing infected mandibular fractures, especially when open reduction and internal fixation with bone plates have been planned.     

Transcutaneous reduction and external fixation for the treatment of noncomminuted zygoma fractures

PURPOSE: This study evaluated the effectiveness of the treatment of noncomminuted monofragment zygoma fractures with closed reduction using transcutaneous threaded pins and an external fixation device instead of open reduction and internal rigid fixation. PATIENTS AND METHODS: In 46 patients, transcutaneous pin was inserted into the center of the fractured zygoma, and the segment was reduced by moving the pin to counteract the initial vector force of injury. After reduction, the fractured segment was immobilized by the external fixation device for 9 to 14 days. RESULTS: All patients except one showed accurate fracture reduction without malunion or any complications. CONCLUSION: This method has advantages over the conventional closed methods in the management of uncomplicated noncomminuted fractures of the zygoma.     

Treatment of isolated distal ulnar shaft fractures with below-elbow plaster cast. A prospective study

In a prospective study 52 patients with an isolated fracture of the distal ulna were treated with a below-elbow plaster cast. The histories of 46 patients were reviewed after a mean follow-up of 3.5 years (ranging from 10 months to 7 years). Forty-three fractures united. There were two non-unions. One fracture displaced while in the plaster, so that there was no longer any bone contact between the fragments. The fracture was consequently treated by open reduction and internal fixation. The type of fracture, the initial displacement (all fractures had bone contact) or the initial angulation (maximum 10 deg) was not found to influence the final clinical results. Below-elbow plaster cast appeared to produce satisfactory results in 89% of the patients.     

Functional analysis of linker insertions and point mutations in the alpha-Amy2/54 GA-regulated promoter

First metatarsal fractures are rare because of their thick size and shape. They are to be treated aggressively because of the prolonged disability associated with such fractures. Any injury to the first ray may drastically alter the pattern of normal gait and weight-bearing. Most of the literature regarding such fractures is anecdotal, and there is little in the way of scientific articles that investigate their management. The general consensus for treatment of closed, nondisplaced first metatarsal fractures is to use some form of plaster immobilization. Nevertheless, there is much variation in the literature concerning the length of time patients should be casted. Rigid internal fixation using AO techniques is preferred if open reduction is to be instituted. Long-term complications with first metatarsal fractures are attributed mostly to malunion in the sagittal plane, resulting in a nonplantigrade foot.     

Clinical and functional outcomes of internal fixation of displaced pilon fractures

The clinical and functional outcomes for patients treated with open reduction and plate fixation of displaced tibial pilon fractures were determined. A retrospective search of the authors' trauma database was conducted for AO and Orthopaedic Trauma Association Code 43 injuries (pilon fractures) in adults 18 years or older who were treated between December 1988 and December 1992. The group of 64 patients who required open reduction and internal fixation to treat their fractures make up the primary cohort for this analysis. Twenty of these cases required no fibular fixation; the remainder were mostly fixed with 1/3 tubular or 3.5-mm compression plates. Tibial fixation was done using most commonly 3.5-mm cloverleaf plates, 1/3 tubular plates, or both. Of the 64 patients treated with open reduction and internal replacement, four (5%) patients had deep infection develop. Two (7%) of 14 patients had open fractures, and two (4%) of 50 patients had closed fractures. Three of these four patients smoked tobacco products; one was also an intravenous drug abuser. Staphylococcus aureus was the organism in two cases; Enterobacter, in the other two. The infection was controlled with a free flap in two cases, with antibiotics and wound debridement in one and with an arthrodesis in one. Thirty of the 64 patients completed the Short Form-36; two of these patients had bilateral fractures. The study group had significant differences in general health perceptions, physical function, physical role function, emotional role function, social and mental function, and pain and energy levels when compared with age matched population data and patients with tibial plateau fractures. The effect of other injuries on these functional status results cannot be determined specifically.     

Closed humeral shaft fractures: a prospective evaluation of surgical treatment

OBJECTIVE: We tried to define the roles of the rigid dynamic compression plate (DCP) and the semi-rigid Ender nail (EN) in the treatment of closed humeral shaft fractures. DESIGN: A prospective, randomized clinical study was performed with detailed comparison parameters. MATERIALS AND METHODS: Ninety-one closed humeral shaft fractures were treated. Randomly, 30 humeri were treated with open reduction and internal fixation with DCP and no bone grafting (BG), 29 were treated with the same procedure but with BG, and 32 were treated with closed reduction and internal fixation with Ender nails. The average follow-up period was 32 months (range, 13-54 months). MEASUREMENTS AND MAIN RESULTS: In the group with DCP without BG, the average blood loss was 270 mL, operation time was 92 minutes, hospital length of stay was 6.5 days, and union time was 12.5 weeks. In the group with DCP with BG, the average blood loss was 325 mL, operation time was 108 minutes, hospital length of stay was 6.9 days, and union time was 9.4 weeks. In the EN group, the average blood loss was 114 mL, operation time was 54 minutes, hospital length of stay was 5.6 days, and union time was 9.9 weeks. Analysis of variance and Fisher's exact test were used to evaluate the statistical significance. CONCLUSION: In our experience, for humeral shaft fractures fixed surgically, EN is better than DCP without BG. When DCP is chosen for the means of fixation, prophylactic BG is recommended, especially in cases with more comminution.     

Kirschner wire placement in the emergency room. Is there a risk?

To evaluate the safety of inserting Kirschner wires into bones or across joints in a setting other than a completely sterile operating theatre, a prospective study of all hand fractures treated by closed reduction and internal fixation was conducted in a mid-city Emergency Department. Indications for percutaneous fixation were displaced, unstable long bone fractures of the hand. 71 fractures in 68 patients were treated, and in 91% the fixation crossed a joint. No patient developed osteomyelitis or pyarthrosis, and there was no deep pin track sepsis. Seven patients with open fractures healed without infection or delayed union. Patients in whom data were available obtained 90% to 95% of the motion of the contralateral digit. The taboo against percutaneous fixation of fractures in a non-operating theatre setting is not warranted. The procedure can be performed with minimal complications in an out-patient setting.     

Controversies in acetabular fractures

Open reduction and internal fixation has become the standard of care for the treatment of most displaced acetabular fractures. As surgical techniques have become refined, long term results of surgical fixation have improved. During the past 10 to 15 years, several controversies have surfaced in the orthopaedic literature regarding the treatment of acetabular fractures. The recent literature regarding acetabular fixation was reviewed. Controversies include the most efficacious surgical approach for complex acetabular fractures; the effectiveness of intraoperative sciatic nerve monitoring; the most effective method of prophylaxis against deep vein thrombosis; and the indications for and method of prophylaxis against heterotopic bone formation.     

Comminuted fractures of the radial head. Arthroplasty versus internal fixation

Fractures of the radial head continue to challenge orthopaedic surgeons. Fortunately, most simple uncomplicated fractures treated non-operatively with emphasis on early motion achieve good results. Treatment of more complex fractures remains controversial, however. When simple radial head excision is contraindicated, choosing between open reduction and internal fixation and radial head replacement remains difficult. A review of the literature does not provide definite guidelines, but suggest that fracture complexity and technique are critical for success. This paper is not intended to review the treatment of radial head fractures, but rather to focus on choosing between replacement versus internal fixation when preservation of radial head mechanics is indicated.     

Acute closed humeral shaft fractures treated with dynamic compression plate

BACKGROUND: To define the efficacy of dynamic compression plates (DCPs) for the treatment of closed humeral shaft fractures. METHODS: A total of 165 patients with closed humeral shaft fractures were studied retrospectively. There were 120 patients who underwent open reduction and internal fixation with DCPs and no bone grafting (BG). Forty-five patients received the same procedures with BG. The mean follow-up period was 93 months. RESULTS: In the DCP without BG group, the average blood loss was 350 ml, operation time was 105 minutes, hospital stay was 8.5 days and fracture union time was 13.5 weeks. In the DCP with BG group, the average blood loss was 525 ml, operation time was 115 minutes, hospital stay was 7.9 days and fracture union time was 9.2 weeks. CONCLUSIONS: In our experience, DCPs are effective for surgical fixation of humeral shaft fractures. Prophylactic BG is recommended for cases with more comminution.     

Arthroscopic reduction and internal fixation of a displaced intraarticular lateral femoral condyle fracture of the knee

Anatomic reduction, typically obtained by direct visualization through an arthrotomy and internal fixation (open reduction and internal fixation), is the traditional treatment method for displaced intraarticular condylar fractures of the distal femur. We present a case report describing an alternative treatment method, namely, arthroscopic reduction and internal fixation, of a displaced, malrotated intraarticular lateral femoral condyle fracture of the knee. The potential benefits of decreased blood loss, shortened operative time, excellent intraarticular visualization, decreased soft tissue dissection, and shortened postoperative recovery are outlined.     

Isolated volar carpometacarpal dislocation of the fifth digit

McWharter first described volar carpometacarpal dislocations of the fifth digit in 1918. Since then, 14 cases have been reported in the medical literature. Berg and Murphy were first to report a case of ulnopalmar dislocation that was successfully treated with closed reduction and immobilization. Previously reported cases required internal fixation with or without open reduction. We report a fifth carpometacarpal ulnopalmar dislocation, treated with closed reduction and casting.     

Open reduction and internal fixation of forearm fractures in children

We retrospectively reviewed 16 children younger than 13 years with 17 fractures of the shafts of the radius or ulna or both who had undergone an open reduction-internal fixation (ORIF). ORIF was performed when a closed reduction was deemed unacceptable in 14 radius fractures and for three unstable open fractures of the radius. The average age was 9.4 +/- 2.3 years (range, 5.0-12.5). Of the 14 fractures with an unacceptable closed reduction, soft-tissue interposition was encountered in seven. Fixation was secured by plates and screws, percutaneous Steinmann pins, or intramedullary Steinmann pins. There were no delayed unions or nonunions, no infections, and no neurovascular injuries. The average follow-up was 12.3 months; all 17 fractures had excellent results (forearm rotation loss of < 10 degrees). Our study indicates that excellent results can be expected with no increased risk of complications if the treating physician elects to proceed with an ORIF in a pediatric forearm fracture with proper indications.     

Forearm fixation

The great majority of forearm fractures in adults are best treated by open reduction and internal fixation. Although alternative methods exist, plate fixation is favored by most surgeons. With strict attention to surgical detail, complication rates are low and early active function is possible. The treatment of high-energy, open fractures can include various techniques such as internal or external fixation. Refracture remains the greatest risk following hardware removal, which is not necessary for all patients.     

Various possibilities for managing subtrochanteric fractures

Subtrochanteric fractures are highly unstable. For treatment, open reduction and internal fixation are the method of choice. The 95 degrees condylar plate is widely used for stabilization of these fractures. Alternative devices are the gamma nail and the recently developed intramedullar nail with a twisted plate which allows immediate postoperative weight bearing. The reported complications of the gamma nail restrict its general application, whereas preliminary reports of the intramedullar nail with the twisted plate are encouraging. Further clinical data are necessary before its general application can be recommended.
