Overview
The prognosis ulnar fracture depends on many factors. However, the factors under the orthopedics surgeons control are: treatment method, timing of internal fixation in open fractures, soft-tissue handling, and restoration of osseous anatomy.
Natural History
- In cases with untreated ulnar bone fracture the malunion and deformity of arm can be occurred[1].
Complication
The type and frequency of complications of the ulnar fracture varies. Its been reported that the ulnar fracture related complication and post-traumatic arthritis rates are 6% - 80% and 7% -65%, respectively. Malunion with an intra-articular or extra-articular deformity non-union, tendon attrition/rupture complications and neurological injuries are the most frequent complication in this regard.
In general the following are the most common complications of ulnar bone fracture[2]:
- Infection of the bone
- Infection of soft tissue
- Compartment syndrome
- Non-union of the fracture
- Mal-union
- Arm shortening
- Radial nerve Damage
- Vascular injury
- Vascular bleeding
- Re-fracture
- Decreased Motion
- Painful movement
Prognosis
The prognosis of ulnar fracture is more guarded for open fractures of the shaft of the ulna with major skin and soft-tissue loss. In these patients, several operative procedures may be necessary, including initial debridement and stabilization, skin grafting, pedicle or free-flap applications, late reconstruction of the bones, and, frequently, tendon transfers[3].
