The paraskeletal clamp-on plate. Part II. Clinical experience with fractures of the radius and/or ulna.

Clinical experience with 282 fractures of the radius and/or ulna treated by means of the paraskeletal clamp-on plate is presented and compared with results for 66 fractures not operated upon and 31 fractures for which conventional plating methods were used. As far as the healing time (average 12,3 weeks) post-healing joint movements, complication rate, morbidity rate, financial outlay, simplicity and versatility are concerned, the paraskeletal clamp-on plate proved to be greatly superior to conventional methods of internal fixation for forearm fractures.

[Results of palmar T-plate osteosynthesis in unstable fractures of the distal radius].

For unstable fractures of the distal radius, the dorsal plate requires exposure of the fragments, frequently spongioplasty, and usually removal of the implant later on. However, with the palmar approach for the reconstruction of the articular surface and restoration can easily be achieved with the T-plate. In the Traumatology Department of the University at Göttingen, we have gained experience in the treatment with the palmar T-plate in more than 400 patients. In a prospective study, we investigated the functional and radiological results after palmar T-plate osteosynthesis in Colles fractures. From September 1994 to December 1998 we treated 200 patients with the palmar T-plate (AO, 3.5 mm, titanium). 166 patients (83%), mean age 59 years, could be followed up >18 months. AO classification: A2:10, A3:45, B1:18, B2:10, C1:24, C2:40, C3:19. We compared group 1 (younger than 60 years, n=88) vs group 2 (older than 60 years, n=78). The patients' evaluation of the usability of the hand was normal in 56% and in 26,5% slightly reduced. 12,5% felt handicapped and 5% felt severely handicapped. 5% of the patients changed the domain hand, 15,4% at least partly. Function according to Lidström: 23% excellent, 58% good, 15% fair and 4% poor results. Radiological results according to Lidström were excellent and good in 88,3% and fair in 11,7%. Gartland and Werley score was excellent in 66%, good in 24%, fair in 6% and poor in 4%. There was no significant difference between group 1 and group 2 in the age-depending results. The secondary dislocation, the average dorsal tilt was 3 degrees, the mean shortening of the radius was 1,5 mm. We saw steps in the joint surface from 0,5-1 mm in 10%. An algodystrophy occurred in 5%. 12% of the patients complained of limited sensitive irritations of the medianus nerve most likely originating in the formerly used approach close to the medianus nerve. After changing this approach, we saw no irritation of the Nervus medianus among 50 patients so far. Evaluation of the functional and radiological investigations: The palmar T-plate has produced reliable and good results in the treatment of unstable distal fractures of the radius without angle-stable screws up to now. This type of osteosynthesis is stable for exercise and ensures early mobilization with good functional results even in elderly patients.

Corrective osteotomy for malunion of the distal radius.

Forty-five patients were reviewed on average 5.7 years after corrective osteotomy for symptomatic distal radius malunion. Restoration of anatomy and function was assessed compared with the contralateral wrist. It was found that osteotomy of the distal radius alone did not completely restore normal anatomy and relieve symptoms, and in several cases a second operation was needed. Osteoarthritic changes in the radiocarpal and radioulnar joints were common, and they correlated with restriction in range of motion, but not with pain. Range of motion and grip power were reduced compared to the unaffected hand, but only loss of supination and ulnar deviation correlated with an unsatisfactory subjective result. The result was good or satisfactory in 33 of the 45 patients. We conclude that reconstructive procedures in patients with distal radius malunion may not completely restore normal function, and every effort should therefore be made to prevent malunion in the treatment of distal radius fractures.

Ultrasonographic localization of a displaced screw in the carpal canal. A case report.

We present a case of a 65-year-old patient with a surgically treated distal radius fracture. At 5-month follow-up, conventional radiography revealed breakage of the plate and a screw displaced into the volar soft tissue. Preoperative ultrasonography including dynamic assessment of the tendons showed the screw intratendinously as a hyperechogenic structure with repetitive echoes. This unusual localization was proven by surgery. Dynamic ultrasonography played an important diagnostic role in the localization of the loosened and displaced osteosynthetic material.

Irreducible distal radioulnar joint occurring in a Galeazzi fracture - case report.

This is a report of an irreducible distal radioulnar joint associated with a Galeazzi fracture. The irreducible dislocation of the radioulnar joint was not appreciated until 2 weeks following compression plating of the radius fracture. The extensor carpi ulnaris was found to be wrapped anteriorly about the ulnar border of the distal ulna and was trapped in this position by the displaced ulnar styloid. The patient was successfully treated with open reduction of the styloid fracture and temporary wire fixation.

Scaphocapitate syndrome in a child associated with a distal radius and ulna fracture.

A case is presented of scaphocapitate fracture syndrome associated with a Salter-Harris type II fracture of the distal radius and ulna occurring in an 11-year-old girl. The proximal fragment of the fractured capitate was rotated 180 degrees. The injury was treated by open reduction and internal fixation. One year after the injury, radiographs showed that fractures were united with no signs of avascular necrosis of the capitate. The patient had a full range of motion of the wrist, as well as full pronation and supination of the forearm. An awareness of this fracture entity is necessary to correctly diagnose this injury in a child.

Extra-articular low-velocity gunshot fractures of the radius and ulna.

Low-velocity gunshot fractures of the forearm are complex injuries and previously published studies have not emphasized the problems particular to these forearm lesions. Of the twenty-nine patients in this series, thirteen had peripheral nerve injuries, three had impending Voklmann's ischemia, and ten had delayed union or malunion of fractures after treatment by closed methods. Only thirteen had none of these problems. Eight patients had long-term disability resulting either from permanent nerve damage with loss of sensation or weakness of grip, or from significant loss of motion following delayed union or malunion. Although external fixation was adequate for undisplaced fractures, delayed (seven to fourteen days) primary internal fixation after the initial phase of wound healing had proved benign gave superior results in displaced fractures.

Pediatric distal double bone forearm fracture remodeling.

Children's bones differ from those of adults in their capacity for ongoing growth and their ability to adapt to a changing body habitus. Similarly, pediatric fractures generally heal more rapidly and have the ability to reshape deformities, a process known as remodeling. The following case exemplifies the remodeling process of a distal radius fracture over time.

Immediate internal fixation of high-energy open forearm fractures.

Eighteen patients with Gustilo and Anderson Grade III A (7), III B (8) or III C (3) open diaphyseal forearm fractures were treated with a protocol consisting of extensive primary debridement, immediate open reduction, dynamic compression plate fixation, and vascular repair when indicated. This was followed by routine redebridement at 24 to 48-h intervals until wound status allowed completion of soft tissue reconstruction. Bone grafting was performed at 8 to 10 weeks following obtainment of a closed soft tissue envelope for injuries with extensive comminution or bone loss (5 patients, 7 fractures). Subsequent procedures such as tendon transfers, scar revision, joint arthrodesis, or secondary nerve reconstruction were required in 8 of 18 patients. Minor complications related to delayed wound healing occurred in 3 individuals (15%). One deep infection of a fractured radius occurred in a patient with a floating elbow and failed free flap. Salvage with debridement, retention of hardware, and a second free flap resulted in fracture union. One patient required a second bone graft to obtain union of a segmental forearm defect. Amputation was performed in one patient following failed forearm replantation with greater than 8 h warm ischemia time. Immediate debridement and plate fixation of Grade III forearm fractures performed in conjunction with aggressive soft tissue management provided good or excellent results in 12 patients (66%) and is an acceptable treatment alternative in these difficult injuries.

[Short-term results of external fixation of unstable distal radial fractures].

OBJECTIVES: We assessed the effectiveness of external fixation in the treatment of unstable distal radial fractures. METHODS: Twenty-five patients (19 males, 6 females; mean age 39 years; range 20 to 71 years) with unstable distal radius fractures were treated by external fixation. Three patients had open fractures. According to the AO classification, the fractures were B1 (1 fracture), B2 (2), C1 (8), C2 (10), and C3 (4). External fixator was combined with K-wires or volar plates in 17 fractures. The fixator was used for a mean of 6.6 weeks, and the mean follow-up was 13.5 months. The earliest radiologic-anatomic and functional evaluations were based on the findings obtained at the end of six months. A modified Sarmiento scoring system was used for radiologic-anatomic assessment. For functional assessment, the scoring system proposed by Sarmiento et al. was used, which was based on the Gartland and Werley's system. RESULTS: Radiologic measurements indicated that anatomical results were excellent in 16 patients (64%), good in eight patients (32%), and fair in one patient (4%). Functional results were excellent in four patients (16%), good in seven patients (28%), fair in 11 patients (44%), and poor in three patients (12%). The complications encountered were pin tract infections in four patients, breakage of the fixator pin holder in one patient, and the development of reflex sympathetic dystrophy in five patients. CONCLUSION: Our data suggest that high success rates in anatomic results do not closely reflect satisfactory functional results. The protocol to be implemented after the application of the external fixator has to be determined according to the type of the fracture.

Loss of flexor pollicis longus function after plating of the radius. Report of six cases.

Six cases of loss of flexor pollicis longus function after plating of a radius fracture are presented. The exact aetiology of the postoperative deficit is uncertain, but is probably a traction neuropraxia of the anterior interosseous nerve branches to the flexor pollicis longus. All six patients had full recovery within 5 months. An initial conservative approach is recommended if this complication is encountered.

T incision for exposure of the distal radius and wrist.

A retrospective review of 66 T-shaped incisions for exposure of the dorsal distal radius and wrist was performed. The incision provided excellent exposure in all cases and no additional incisions were required. Cosmesis was considered acceptable by all patients. Complications occurred in 6% and were more likely in patients undergoing fixation of acute distal radius fractures using Kirschner wires which protruded through the skin flaps.

Assessment of osteoporosis using standard radiographs of the wrist.

BACKGROUND: This study evaluated the ability of the orthopaedic surgeon to radiographically assess bone density in the wrist with sufficient accuracy to determine which patients require treatment for osteoporosis. METHODS: Thirty-eight patients with unilateral distal radius fractures, 30 of whom were female, were included in this study. The mean age was 55 years (range 45 to 82). Standard radiographs of the fractured and normal wrists were taken. Dual energy x-ray absorptiometry was performed on the normal distal radius of all patients within 1 week of their injury. The radiographs were viewed in blinded randomized fashion on two separate occasions by three orthopaedic surgeons and once by a fourth. The participants were required to determine the presence of osteoporosis. Visual analog scales (VAS) were used to evaluate (1) porosity, (2) cortical thickness, (3) trabecular thickness, and (4) the number of trabeculae in the ultradistal radius. RESULTS: Intraobserver agreement assessing osteoporosis averaged 81% (kappa of 0.5393). VAS assessment was unreliable for all four parameters. Radiographic determination of osteoporosis had a specificity of 61% and a sensitivity of 61% using x-rays of the uninjured wrist. CONCLUSION: We conclude that orthopaedic surgeons cannot predict with sufficient accuracy using plain x-rays whether a patient is significantly osteoporotic.

Sliding osteotomy for deformity correction following malunion of volarly displaced distal radial fractures.

OBJECTIVE: To determine the outcome after a sliding osteotomy for deformity correction following malunion of volarly displaced distal radius fractures. DESIGN: Retrospective review of a consecutive patient series. SETTING: A university-affiliated, tertiary-care center. PATIENTS/INTERVENTION: Ten patients with symptomatic distal radius malunion following a volarly displaced distal radial fracture (Smith's fracture) were treated with an oblique sliding osteotomy and plate fixation, through a volar approach, without using an iliac crest bone graft. Five men and five women with an average age of 41.9 years were followed for an average of 2.7 years postoperatively. MAIN OUTCOME MEASUREMENTS: Range of motion, grip strength, Fernandez wrist score, radiographic parameters. RESULTS: At latest follow-up, wrist extension improved from an average of 37 degrees preoperatively to 70 degrees postoperatively (P = 0.002), wrist flexion improved from an average of 40 degrees to 65 degrees (P = 0.012), and supination improved from an average of 31 degrees to 68 degrees (P = 0.002). Postoperative radiographs revealed an average deformity correction of 10.6 degrees of volar tilt, 7.7 degrees of radial inclination, 5.8 mm of ulnar variance, and 10.4 mm of volar translation. Using the Fernandez point score (0-20) system, the average overall score improved from 10.5 preoperatively to 17.6 postoperatively (P = 0.0001). Functional outcome was rated as excellent or good in 9 of 10 patients and fair in 1 patient (who experienced residual problems due to persistent ulnar-sided pain). There were two reoperations (one hardware removal, one distal ulnar hemiresection). CONCLUSIONS: This method reliably restores distal radial anatomy, decreases pain, and improves supination without requiring iliac crest bone grafting.

[Fracture of the distal ulna accompanying fracture of the distal radius. Minimally invasive treatment with elastic stable intramedullary nailing (ESIN)].

The distal radius is one of the commonest sites of fracture, and this injury is sometimes associated with fracture of the distal ulna. In recent years, surgical treatment of distal radius fractures has consisted increasingly in internal fixation with locking plates followed by early functional postoperative treatment. The associated injury to the distal ulna has so far not received much attention in the literature. Various techniques have veen described for its treatment: Kirscher wire fixation, tension band wiring, and internal fixation with screws and plates. Following positive results with elastic stable intramedullary nailing (ESIN) in the treatment of shaft fractures in children this technique was also applied in in fractures in adults (forearm, clavicle). Use of this technique for stabilisation of distal ulnar fractures has not previously been reported. In the course of a prospective longitudinal study (EBM level II), in 26 patients with an average age of 73.6 (42-88 years), bone healing in anatomical position was achieved in all cases within 6-12 weeks after closed reduction and anterograde ESIN with subsequent treatment that did not involve immobilization. No length differences of more than 2 mm and no functionally relevant deviations of the ulnar axis were observed. Apart from 3 cases of nail perforation at the distal end of the ulna, which had no clinical manifestations, there were no complications. ESIN offers a minimally invasive option for the treatment of unstable fractures of the distal ulna associated with distal radius fractures; it allows functional aftertreatment and can be regarded at least as an alternative to open reduction with internal fixation.
