A New Modification of Corrective Osteotomy for Treatment of Distal Radius Malunion

A new modification of corrective osteotomy for distal radius malunion, which minimizes the need for bone grafting and addresses the constraining aspect of the extensor retinaculum, is described. This new modification uses a volar and dorsal approach to perform an angled step-cut osteotomy, release of the extensor retinaculum, and volar plating. The typically dorsally extruded comminuted fracture fragments from the distal, dorsal compression fracture component of the distal radius fracture is mobilized with the distal fragment and acts as a dorsal strut graft to span the opening wedge, corrective osteotomy. Therefore, this new modification facilitates and improves the realignment of the malunited radius, while minimizing or eliminating the need for bone grafting.

Mini-Screw Fixation for the Treatment of Proximal Interphalangeal Joint Dorsal Fracture–Dislocations

Surgical intervention may be necessary to treat unstable dorsal fracture-dislocations of the proximal interphalangeal (PIP) joint of the hand. One method of stabilization is open reduction and internal fixation (ORIF). The purpose of this study was to assess the outcomes of ORIF for unstable dorsal fracture-dislocations of the PIP joint using mini-screws via a volar approach. A retrospective chart review with clinical follow-up evaluation was performed on 9 patients who had ORIF for unstable dorsal fracture-dislocations of the PIP joint. The fracture fragment(s) from the middle phalangeal base were reduced and secured using mini-screws. A clinical evaluation was performed at an average of 42 months after surgery. The average arc of motion for the involved PIP joint was 70 degrees (range, 55 degrees -90 degrees ). The average PIP joint motion in the 2 patients with 1 fracture fragment was 85 degrees , and the average PIP joint motion for the remaining 7 patients was 65 degrees . One joint was subluxated with an intra-articular screw. Nine patients had an average flexion contracture of 14 degrees . Seven patients had no pain, and 2 had pain only with heavy activity. Open reduction and internal fixation of unstable dorsal PIP joint fracture-dislocations using mini-screws can be considered if the fracture fragment(s) can accommodate the screws. The procedure attempts to restore the concave contour of the middle phalangeal base and permits early protected range of motion. The procedure should be approached cautiously, especially in the presence of comminution. Proximal interphalangeal joint range of motion is usually compromised; 8 of our 9 joints had a residual flexion contracture. Therapeutic IV.

Comparison of Radiography and Computed Tomography to Evaluate Metacarpo/Metatarsophalangeal Joint Pathology of Paired Limbs of Thoroughbred Racehorses with Severe Condylar Fracture

To compare the orthogonal radiographic (OR) and computed tomographic (CT) appearance of paired Thoroughbred racehorse limbs with severe condylar fracture. In vitro study. Cadaveric paired limbs with severe condylar fracture (n=11 horses). Four standard radiographic and multiple transverse CT images were obtained of the fractured and contralateral limbs centering on the metacarpo/metatarsophalangeal (fetlock) joints. Radiographs and CT images were graded by 4 raters, and interobserver agreement was calculated. Imaging evaluations were supplemented by fetlock joint dissection. A consensus description of actual injury and the detection accuracy of OR and CT for that injury was determined. Results- Rater agreement for OR and CT for most pathologic features was good or excellent. OR was similar to CT for the detection of condylar and diaphyseal third metacarpal and metatarsal (MC/MT3) fractures, diaphyseal fractures of the first phalanx (P1), and fracture location on the condyle. CT was superior to OR for detection of MC/MT3 proximal fissures and articular comminution, condylar small cracks and lucencies, and proximal sesamoid fractures. OR was superior to CT for detection of proximal P1 dorsal fractures. Both OR and CT were poor at detecting palmar/planter proximal P1 fractures and coalescing cracks in the subchondral bone of MC/MT3. CT is better than OR for detection of pathology in limbs with condylar fractures, but does not detect every pathologic feature. CT provides superior information of pathology in Thoroughbred racehorses with condylar fractures.

Acute adrenal hemorrhage after blunt trauma

To determine the appropriate management of adrenal hemorrhage in patients with severe chest and upper abdominal blunt trauma. We reviewed 7 patients who suffered from severe traumatic adrenal hemorrhage after a traffic accident (n = 4) or fall (n = 3). Contrast-enhanced CT images were analyzed for multi-organ traumatic injury, hematoma size, extravasation, and pseudoaneurysm formation. We also report their management including transarterial embolization (TAE) and follow-up findings. All 7 patients manifested multi-organ traumatic injury and hemothorax; 5 also had rib fractures, 5 had abdominal organ injuries (liver, n = 3; kidneys, n = 2; pancreas, n = 1); 2 had dorsal fractures, and 1 had a traumatic aortic aneurysm. On CT images, unilateral right adrenal hematomas ranging from 20 to 50 mm (mean 26 mm) in length and from 15 to 50 mm (mean 23 mm) in width were seen. In 6 patients these were localized, and they were followed without any intervention. The other patient had a massive hematoma with pseudoaneurysm and extravasation, who subsequently received TAE. At 3-month follow-up all patients were doing well. Information regarding the size of the hematoma and the presence of extravasation helps to select the appropriate management of patients with traumatic adrenal hemorrhage. TAE appears to be useful for treating patients with massive adrenal hemorrhage.

Dorsal fracture dislocations of the proximal interphalangeal joint treated by open reduction and interfragmentary screw fixation: indications, approaches and results

Many operative and non-operative treatments of dorsal fracture dislocations of the proximal interphalageal (PIP) joint have been described. Return of good joint function requires anatomical reduction of the articular fragments and restoration of joint congruity and a stable functional arc of motion, with the fixation construct stable enough for early mobilization. To prevent recurrent dorsal subluxation, the attachments of the ligamentous palmar restraints and the bony buttress provided by the palmar lip of the middle phalanx base must be restored. Open reduction and internal interfragmentary screw fixation using 1.5 or 1.3mm screws was employed in 12 fingers in 10 patients with unstable dorsal fracture dislocations of the PIP joints of Schenck grades III and IV. At an average follow-up of 8.7 months, all patients in this series achieved good to excellent results and an average total active interphalangeal motion of 132 degrees (range 105 degrees -165 degrees). Additional benefits over non-operative techniques included improved patient comfort and simplified nursing care and therapy supervision.

Dorsal Fracture–Dislocation of the Proximal Interphalangeal Joint: A Comparative Study of Percutaneous Kirschner Wire Fixation Versus Open Reduction and Internal Fixation

Nineteen patients with a dorsal fracture-dislocation of the proximal interphalangeal joint of a finger were treated with either closed reduction and transarticular Kirschner wire fixation (eight cases) or open reduction and internal fixation, using either one or two lag screws (six cases) or a cerclage wire (five cases). At a mean follow-up of 7 (range 6-9) years, most patients reported satisfactory finger function, even though some of the injuries healed with proximal interphalangeal joint incongruency (seven cases) or subluxation (four cases). Those treated by open reduction complained of more "loss of feeling" in the affected finger and those specifically treated by cerclage wire fixation reported more cold intolerance and had a significantly larger fixed flexion deformity (median, 30 degrees : range 18-38 degrees ) and a smaller arc of motion (median, 48 degrees : range 45-60 degrees ) at the proximal interphalangeal joint, despite having the best radiological outcomes. Closed reduction and transarticular Kirschner wire fixation produced satisfactory results, with none of the eight patients experiencing significant persistent symptoms despite a reduced arc of proximal interphalangeal joint flexion (median=75 degrees ; range 60-108 degrees ). The results of this relatively simple treatment appear at least as satisfactory as those obtained by the two techniques of open reduction and internal fixation, both of which were technically demanding.

Fractures récentes des articulations IPP

Recent PIP fractures are challenging trauma in terms of diagnosis as well as treatment. It must be remembered that the final outcome will have a considerable impact on the global finger and hand function. Immediate mobilization and rehabilitation are mandatory, and may justify a surgical approach and fixation in selected cases. A good understanding of the fracture type is essential and relies in good part on precise, focused and standardized radiographs. Non-displaced fractures are generally treated conservatively. In the proximal phalanx, the orientation of the fracture line dictates the stability of the fracture. Thus non-displaced fractures can occasionally be preventively stabilized, in order to allow early mobilization. Displaced fractures should always be anatomically reduced and surgically fixed. A temporary joint stabilization is optional. In the middle phalanx, one must consider palmar and dorsal fractures differently. Palmar fractures include a distal palmar plate avulsion. The degree of impaction will dictate the stability of the joint towards dorsal subluxation. Dorsal fractures include central slip avulsion of the extensor tendon. An antomical reduction and surgical fixation is mandatory to avoid a progressive boutonniere deformity. Prognosis of all the middle fractures is closely dependent on the degree of impaction. When direct osteosynthesis is not possible, distraction devices, bone graft or palmar plate reconstruction may be useful alternatives. In complex fractures, bone fixation and joint stabilization must be combined in order to prevent secondary displacement and joint instability.

Volar barton’s fractures with concomitant dorsal fracture in older patients

Purpose To describe a variant of Barton’s volar articular shearing fracture of the distal radial articular surface with a subtle concomitant fracture of the dorsal metaphyseal cortex. Methods This fracture pattern was observed in 6 women and 2 men with an average age of 67 years (range, 58–76 years). All 8 patients were treated with a volar plate and screws. The dorsal metaphyseal fracture was not recognized in 5 patients and a volar buttress plating technique using an intentionally undercontoured volar plate was used. In 3 patients the dorsal fracture line was identified before surgery and the plate was contoured to fit the volar surface of the distal radius. Results All 5 patients treated with an undercontoured plate had loss of the normal palmar tilt of the distal radius (average,–9.4°; range, 0° to–22°) and dorsal translation of the distal radial articular fragments. For the entire group the palmar tilt averaged–5.9° (range, 0.0° to–22.0°), the ulnar inclination 19° (range, 10°–23°), and the ulnar variance–0.9 mm (range, 0.0 to–3.0 mm). All patients attained forearm supination of 80° and the average pronation was 75° (range, 45°–80°). According to Sarmiento’s modification of the system of Gartland and Werley there were 1 excellent, 6 good, and 1 fair results. The average Patient-Rated Wrist Evaluation score was 16 (range, 0–35). Conclusions Some fractures with an oblique volar marginal articular fracture of the distal radius and volar radiocarpal subluxation (known as Barton’s fracture) may also have a fracture through the dorsal metaphyseal cortex. Failure to identify this fracture line can lead to dorsal translation and angulation of the distal radius articular surface, particularly when an undercontoured volar plate is used for internal fixation.

Dynamic external fixation for complex intraarticular phalangeal fractures

Intraarticular phalangeal fractures are difficult to treat. The advantages of using dynamic external fixation devices include distraction of impacted fracture fragments and reduction in joint stiffness by allowing early joint mobilization. Previous reports have concentrated on pilon fractures and dorsal fracture dislocations affecting the proximal interphalangeal joint. We report our experience using a dynamic external spring fixator in the management of 15 patients with a variety of fracture patterns affecting the metacarpophalangeal, proximal interphalangeal and distal interphalangeal joints. In three cases the device spanned two adjacent joints. Long-term follow-up has shown excellent range of joint movement and no major complications. We consider that this device is an effective tool in the management of a range on complex intraarticular phalangeal fractures.

Intramedullary bone cementing for the treatment of Colles fracture in elderly patients.

Eighteen patients with Colles fractures, mean age 70 years (range 55-91), were treated by intramedullary bone cementing. The best indication for this technique was an unstable extra-articular Colles fracture with osteoporosis. Bone cement was packed into the canal that was made by curettage of intramedullary cancellous bone from the dorsal fracture site. Intramedullary cementing caused little bleeding from the medullary canal and no irritation of the extensor tendons. Because of rigid fixation, patients could use the affected hand for light activities without any external orthosis the day after surgery. Cortical healing was seen in all cases within three months and there was no cement loosening or other complications during the mean 28 month (range 6-43) follow up period. Intramedullary bone cementing is one of the optimal treatments for Colles fractures in elderly patients.

Minimalinvasive Therapie der dislozierten distalen metaphysären Radiuskompressionsfraktur: klinische und radiologische Ergebnisse nach gedeckter Reposition, Stiftfixation und stabiler Defektauffüllung mit einer porösen Hydroxylapatitkeramik

Von April 1994 bis Dezember 1995 wurden 14 Patienten (13 Frauen, 1 Mann) mit einem Durchschnittsalter von 57 (41 - 71) Jahren wegen einer distalen metaphysären Radiuskompressionsfraktur (Extensionsfrakturen der Gruppe I nach Pechlaner, AO-Klassifikation: A2- und A3-Fraktur) minimalinvasiv versorgt. Die Fraktur wurde gedeckt reponiert und mit 1,8-mm-Kirschner-Drähten stabilisiert. Der dorsale metaphysäre Stauchungsdefekt wurde mit einer Hydroxylapatitkeramik (Endobon®) aufgefüllt. Der Nachuntersuchungszeitraum betrug im Mittel 39 (24 - 50) Monate. Nach dem Score von Gartland und Werley erreichten 85 % der Patienten ein sehr gutes bis gutes Ergebnis. Nach dem radiologischen Score von Lidström erreichten 92 % der Patienten ein sehr gutes bis gutes Ergebnis. Mit diesem minimalinvasiven Verfahren konnten wir in unserem Patientengut gute klinische und radiologische Ergebnisse erzielen. Ein geringes Nachsinken der Gelenkfläche in die Stauchungszone konnte nicht verhindert werden.

Volar plate arthroplasty of the distal interphalangeal joint.

Ten patients with chronic dorsal fracture subluxation of the distal interphalangeal joint were managed over 5 years with volar plate advancement arthroplasty. The mean time from injury to definitive surgical treatment was 8 weeks (range, 2 weeks to 4 months). All injuries were characterized by volar comminution and impaction of the distal phalanx, with associated dorsal subluxation. Surgical treatment included volar plate advancement arthroplasty and K-wire fixation of the reduced joint for 4 weeks. All patients were evaluated at an average postoperative duration of 25 months (range, 10-60 months). The average arc of motion of the distal interphalangeal joint of the 4 fingers (6) was 42 degrees and of the interphalangeal joint of the thumb (4) was 51 degrees. All patients had a residual flexion contracture averaging 12 degrees (range, 6 degrees to 25 degrees ). Volar plate advancement arthroplasty is an effective treatment for chronic distal interphalangeal joint dorsal fracture subluxation.

PROXIMAL INTERPHALANGEAL JOINT FRACTURE DISLOCATIONS

Proximal interphalangeal joint fracture dislocations are complex, potentially disabling injuries for any patient, especially the competitive athlete. Dorsal fracture dislocations are fairly common and volar fracture dislocations are rare. Stable injuries often heal with minimal functional deficit, whereas unstable injuries can result in limitation in range of motion, joint incongruity, and degenerative joint disease. A number of surgical procedures have been described to treat the unstable dorsal fracture dislocation, including ORIF, extension block pinning, external fixation, dynamic traction, and volar plate arthroplasty. Volar fracture dislocations are usually amenable to closed or open reduction and internal fixation. The results of treatment of both volar and dorsal fracture dislocations can be unpredictable.

Dorsal fracture dislocations of the proximal interphalangeal joint: surgical complications and long-term results.

This retrospective study assessed the short-term complications and long-term subjective and objective results of operative treatment of acute unstable dorsal proximal interphalangeal joint dislocations treated by 2 methods: open reduction internal fixation and volar plate arthroplasty. Fifty-six patients were included in this study. Twenty-three (41%) were treated by volar plate arthroplasty and 33 (59%) were treated by open reduction internal fixation. Postoperative complications occurred in 10 patients (18%). The most frequent complication was redislocation, which occurred in 6 patients (volar plate arthroplasty, 3 patients; open reduction internal fixation, 3 patients) and necessitated salvage surgery in 4 of these 6 cases. In all 6 cases, the fracture of the base of the middle phalanx involved more than 50% of the articular surface. Twenty-four patients (43%) returned for long-term evaluation at an average follow-up period of 46 months (range, 13-125 months). Twenty of these 24 patients (83%) reported little or no pain despite a high incidence (96%) of posttraumatic degenerative changes. Eighteen (75%) reported no difficulty with work activities; 92% continued leisure activities with little or no modification. Proximal interphalangeal joint flexion contractures and extension lag at the distal interphalangeal joint were common. These data indicate that if reduction is maintained, patients may expect few functional deficits despite radiographic degenerative changes and loss of mobility.

Cerclage fixation for fracture dislocation of the proximal interphalangeal joint.

Dorsal fracture dislocations of the proximal interphalangeal joint remain 1 of the most difficult problems in which to obtain an excellent functional outcome. The use of minimally invasive internal fixation techniques improving the biologic healing response and yet providing fracture fragment stabilization has met with greater popularity in recent years. The results of 12 patients treated by the volar cerclage wiring technique are described. At average followup examination of 2.1 years, 11 of 12 patients were noted to have no degenerative joint changes with only 1 patient having evidence of early volar articular surface beaking. Average final active arc of motion at the proximal interphalangeal joint was 89 degrees (range, 72 degrees - 109 degrees). The average degree of extension loss at the proximal interphalangeal joint was 8 degrees (range, 0 degrees - 16 degrees). There were no complications involving implant failure, irritation, or infection. A description of the volar cerclage wire technique is presented. This technique provides the advantage of avoiding fracture fragment stripping, stable restoration of the articular surface, and palmar buttress of the middle phalanx at the proximal interphalangeal joint.

Swan-neck deformity as a complication of the agee technique

Unstable dorsal fracture dislocations of the PIP joint of a finger commonly result in joint stiffness following immobilization or open reduction and internal fixation (Green and Rowland, 1984). The Agee dynamic external fixator, or force couple splint (Agee, 1978; 1987), was introduced in an attempt to avoid this complication and maintains a concentric reduction whilst allowing a full range of joint movement. The splint is constructed from three Kirschner wires and is activated by a single rubber band. A force couple is created across the proximal interphalangeal joint levering the base of the middle phalanx towards the palm whilst simultaneously lifting the distal end of the proximal phalanx dorsally to restore joint reduction. However, this technique is not without complications (Agee, 1987). We report a swan-neck deformity resulting from this treatment.
