External fixation of unstable metacarpal and phalangeal fractures.

A prospective study of the management of 30 patients with 37 unstable or complex metacarpal or phalangeal fractures treated with the "Shearer" micro-external fixator was carried out over an 18-month period. The stability achieved, with minimal soft-tissue tethering, allowed early joint mobilisation with good or excellent function in 94% of metacarpal and 85% of phalangeal fractures by nine weeks. There were no cases of non-union and few complications.     

Rigid fixation of phalangeal and metacarpal fractures

Rational use of rigid fixation in hand surgery requires awareness of the advantages as well as the potential pitfalls of this relatively complex method of fracture management. A rational decision also necessitates familiarity with closed techniques of internal fixation which, in most cases, provide superior alternatives for the phalanges and metacarpals. The optimal application of screws, plates, and tension-band wires to small bone fractures can be ascertained only by critical assessment of large series of cases employing these devices and comparisons with similar series using other techniques of internal fixation. Nonetheless, rigid fixation is the logical choice for treatment of unstable fractures when other methods are predictably less effective. Injuries most suitable for screw or plate fixation include displaced phalangeal condylar fractures, irreducible oblique phalangeal fractures, irreducible transverse metacarpal fractures, disabling malunions, and nonunions requiring multiple adjunctive procedures. For selective fractures, especially those with established deformity or serious joint contractures, the capacity of rigid fixation to effect immediate skeletal stability and facilitate early digital motion can considerably enhance recovery. Complications are minimized by precision--in case selection and surgical techniques.

External fixation of closed metacarpal and phalangeal fractures of digits. A prospective study of one hundred consecutive patients

Stable and undisplaced phalangeal and metacarpal fractures treated with strapping or functional splinting and controlled active exercises offer from about 70 to 80% of good results. The goal of treatment of closed unstable and displaced fractures should be to achieve similar or better outcome. External fixation combines the simplicity of time-honoured fixation with K-wires and an external frame to increase rigidity. This combination was used in a prospective study of 100 consecutive patients with closed fractures of the proximal and middle phalanges and the distal three-quarters of the metacarpal bones. Good clinical results (TAM > or = 230 degrees) were obtained in 76% of isolated phalangeal fractures, in all metacarpal fractures and in 89% of multiple fractures.     

Composite wiring of metacarpal and phalangeal fractures

Composite wiring techniques using various configurations of Kirschner pins and stainless steel wire sutures have been applied to the treatment of 63 fractures of the long bones of the hand. The secure fixation achieved allowed active motion within 1 week of operation. Thirty-three metacarpal fractures achieved a final mean total active motion of 256 degrees (standard deviation 13.4) (normal total active motion -260 degrees). Twenty-one phalangeal fractures achieved a mean total active motion of 215 degrees (standard deviation, 46 degrees). There were no instances of infection, malunion, nonunion, loss of reduction, or tendon rupture in the 63 fractures that were treated.

Derotation taping for metacarpal and phalangeal fractures

Derotation taping for metacarpal and phalangeal fractures is a simple, noninvasive technique for management of acute fractures with malrotation. Ulnar nerve or ring block is performed followed by a closed reduction using a Jahss technique and then a rotatory manipulation. Plaster tape is applied, providing a supination torque on the finger. Those patients with a late presentation of a rotatory malunion are managed with a "K wire osteoclasis" which involves multiple percutaneous cortical K-wire perforations and then a manipulation.     

Operative treatment of metacarpal and phalangeal shaft fractures

Diaphyseal fractures of the metacarpals and phalanges are common injuries that can lead to impairment of hand function. The fracture pattern and soft-tissue injury vary with the mechanism of injury. The imbalance of the flexor and extensor forces created by displaced fractures will often produce a secondary angulatory deformity. Nonoperative treatment is indicated for reducible and stable fracture configurations. Irreducible or unstable fracture patterns require open or closed reduction and fixation. Reduction must be assessed in flexion and extension to ensure correct rotatory alignment. Fracture fixation can be achieved with the use of Kirschner wires, interfragmentary screws, or plates. The outcome after surgery is greatly influenced by the condition of the surrounding soft tissues; therefore, surgical trauma should be minimized to optimize the result.

Self-reinforced bioabsorbable versus metallic fixation systems for metacarpal and phalangeal fractures: a biomechanical study

Bioabsorbable fixation devices offer a useful option to treat small bone fractures of the hand if the prerequisite of reliable and stable osteofixation is met. We compared the stabilities of various bioabsorbable fixation devices with metallic fixation devices by using an oblique osteotomy model in radial to ulnar orientation. The 1.5-mm, self-reinforced, poly-L-lactide (SR-PLLA) pins provided fixation rigidity comparable with 1.5-mm K-wires in dorsal and palmar apex bending, whereas in lateral apex bending and in torsion the rigidity was equal to that of 1.25-mm K-wires. The 2.0-mm, self-reinforced, poly-L/DL-lactide (SR-P(L/DL)LA) 70/30 screws provided rigidity comparable with that of 1.5-mm K-wires in all testing modes. The bioabsorbable plate considerably enhanced the bending stabilities of the fixation system, but a single interfragmentary screw provided only limited rotational rigidity. The results show that by using ultra-high strength self-reinforced implants adequate fixation stability for hand fracture fixation can be achieved.
