Abstract:
Objective To evaluate effects of minimal invasive plating for treatment of mid-distal humeral shaft fractures.Methods From May 2004 to December 2007, 20 patients with isolated unilat-eral mid-distal third humeral shaft fractures were surgically treated with close reduction and internal fixation using a 4.5 mm dynamic compression plate which was anteriorly inserted through 2 small incisions on the anterior aspects of proximal and distal parts of the arm, away from the fracture site.The postoperative function of the radial nerve and the musculocutaneous nerve, the postoperative alignment of the main fragments on the anteroposterior radiographs, the bone healing time and muscle strength of biceps muscles were measured and recorded, Results Four patients complained of numbness at the area innervated by the lateral ante-braehial cutaneous nerve in the affected forearm after the surgery.No signs of iatrogenic radial nerve palsies occurred after the surgery.A completely normal alignment was achieved in 7 patients, but varus of 11° was found in 2 cases and varus of 2°, 3°, 4°, 5°, 6°, 7° and 10° in one each.Valgus deformity was noticed in 4 cases, and valgus of 3°, 4°, 6° and 7° in one each.The mean follow-up of 10.4 months for 19 patients re-vealed bony union of all the fractures.The average bone healing time was 13.4 weeks.At the latest follow-up, the biceps muscle strength of all the patients was 5 degrees.Hardwires were removed in 5 patients without any complications.Conclusions Minimally invasive anterior plating is a safe alternative osteosynthesis for mid-distal third humeral shaft fractures.However, this technique may interfere with the function of the lateral antebrachial cutaneous nerve.
