Hoffmann® Micro Lengthener
External fixation system
Developed for metacarpal, metatarsal, or phalangeal lengthening the Hoffmann Micro Lengthener, may also be used for compression in arthrodesis or non-union cases. The overall size of the fixator makes it one of the most compact devices offered today. The low profile 6mm tube and clamp assembly is excellent for patient comfort, while still intending to maintain secure strength and durability.
Optional thumb wheel helps the patient follow the regime of daily lengthening.
Clamps can be positioned in a variety of ways to allow for optimal pin placement, easy frame adaptability, and access to the locking nuts.
Clamps allow insertion of Apex Pins in parallel, convergent, or divergent directions.
Procedures
Brachymetatarsia
The treatment of brachymetatarsia involves lengthening of a short, or hypoplastic, metatarsal.

1st Metatarso-phalangeal (MTP) Arthrodesis
A first MTP arthrodesis can be performed in cases of arthritis (hallux rigidus) or deformity. The goal is to fuse (or permanently stiffen) the first metatarsal and proximal phalanx.

Closing Wedge Osteotomy
A lateral closing wedge osteotomy of the first metatarsal is performed to treat Hallux Valgus deformities.

Navicular Fracture
Navicular fractures can occur as stress fractures, as commonly seen in athletes, or related to acute trauma.

Calcaneal Fracture
Fractures of the calcaneus – or heel bone – most often occur after falls from heights or motor vehicle collisions. Treatment of calcaneal fractures may require surgery.

Ankle Distraction
A distraction arthroplasty stretches the ankle joint apart over a period of time. This effectively unloads the joint, allowing it to heal. An ankle distraction arthroplasty is most commonly used for patients with ankle arthritis without deformity.

Ankle Fracture
Ankle fractures are one of the most common fractures to occur. These can involve the lateral malleolus (fibula), medial malleolus, and/or the posterior malleolus. The syndesmosis may also be involved. Ankle fractures can also involve the articular surface of the tibia, known as pilon fractures. To provide stability and allow for an anatomic reduction, some of these fractures are treated surgically.
