ObjectiveTo investigate the management strategies of clavicular fracture combined with brachial plexus injury and its effectiveness. MethodsBetween January 2006 and January 2012, 27 cases of clavicular fracture combined with brachial plexus injury were treated. There were 18 males and 9 females, aged 18-42 years (mean, 25.3 years). The causes of injury were traffic accident in 12 cases, falling from height in 10 cases, bruise in 3 cases, machinery injury in 2 cases. According to the Robinson classification, the clavicular fractures were rated as type Ⅰ in 2 cases, as typeⅡin 20 cases, and as type Ⅲ in 5 cases; there were 12 cases of total brachial plexus root avulsion injury, 10 cases of bundle branch injury, and 5 cases of hematoma formation and local nerve compression or injury. The injury to operation time was 6 hours to 14 days (mean, 4 days). Brachial plexus injury was repaired by epineurium neurolysis, nerve anastomosis, or nerve transposition after the exploration of the plexus; and fracture was fixed after open reduction. Sensory grading standard (S0-S4) by UK Medical Research Council (MRC) was used to evaluate the recovery of sensory function, and muscle strength grading standard (M0-M5) by MRC to evaluate the innervating muscle strength. ResultsThe incisions healed by first intention. All patients were followed up 18-36 months (mean, 26.3 months). All fracture achieved cl inical healing at 12-17 weeks (mean, 15 weeks). No complication of loosening or breakage of internal fixation occurred. The patients had no pain of shoulder in abduction. At 18 months after operation, the shoulder abduction was more than or equal to 60° in 8 cases, 30-60° in 8 cases, and less than 30° in 11 cases. The recovery of biceps muscle strength was more than or equal to M3 in 18 cases and less than M3 in 9 cases; the recovery of wrist flexion or flexor muscle strength was more than or equal to M3 in 13 cases and less than M3 in 14 cases. The sensory function recovery of median nerve was S3 in 14 cases, S1-S2 in 9 cases, and S0 in 4 cases. The shoulder abduction, elbow and wrist flexor motor function did not recover in 2 patients with total brachial plexus root avulsion injury. ConclusionIt is beneficial to the recovery of nerve function to early repair of the brachial plexus injury by exploration of the plexus combined with open reduction and fixation of clavicular fractures, the short-term effectiveness is good.
Objective To explore the clinical effect of different types of free tissue transplantation on repairing tissue defects and reconstructing functions. Methods From November 2001 to September 2004, 14 types of freetissue transplantation and 78 free tissue flaps were applied to repairing tissue defects and reconstructing functions in extremities and maxillofacial region in 69 cases. Of the 69 cases, there were 53 males and 16 females (their ages ranged from 18 to 56, 31 on average). Five cases were repaired because of skin defects in foot, 22 cases were repaired because of skin defects in leg, 36 cases were repaired as the result of skin defects in hand or forearm and finger reconstruction, 3 cases were restored by virtue of ulna or radius defects, and 3 cases were repaired in maxillofacial region. There were 55 cases of open wound, in which 16 cases were infectious wound, 6 cases were osteomyelitis or pyogenic arthritis. There were 14 cases of noninfectious wound. The area of these tissue flaps ranged from 2.0 cm×1.5 cm to 43.0 cm×12.0 cm. The length of bone transplantation ranged from 10 cm to 15 cm. Results Arterial crisis occurred in 2 cases, venous crisis occurred in 2 cases.Seventysix flaps survived completely and 2 flaps survived partially which werelater healed. Fiftytwo cases were healed at stageⅠ, 13 cases were healed at stageⅡ(healing time ranged from 20 to 30 days), purulent infection occurred to 4cases(healing time ranged from 3 to 11 months). Bone healing time ranged from 6 to 8 weeks in finger reconstruction. Bone healing time ranged from 4 to 6 months in fibula transplantation. The function reconstruction and appearance were satisfying. The functions of all regions, where free tissues were supplied, were not disturbed. Conclusion Tissue transplantation and composite tissue transplantation are effective in repairing tissue defects and reconstructing functions.
OBJECTIVE To improve the clinical result of repair on flexor tendon injury, and recover the defected finger function in children as far as possible. METHODS From January 1990 to October 1997, 12 cases with flexor tendon injury were repaired by microsurgical technique, sutured by modified Kessler method with 3/0 or 5/0 nontraumatic thread and followed by invering suture of the gap edge with 7/0 or 8/0 nontraumatic thread after debridement. Appropriate functional practice was performed postoperatively. RESULTS All the defected fingers were healed by first intention. Followed up 6 months to 1 year, there was excellent in 7 cases, better in 4 cases, moderate in 1 case and 91.67% in excellent rate according to the TAM standard of International Hand Committee. CONCLUSION The important measures to improve the clinical result in children’s flexor tendon injury are prompt and accurate diagnosis and repair of the injured tendon by microsurgical technique, and effective postoperative functional practice.
OBJECTIVE To introduce a skin flap containing the middle cutaneous branch of the medial plantar artery. METHODS Microanatomic study was performed on 8 fresh cadaveric feet, the arteries were dissected and infused with methylene blue to observe their vascular distribution and the skin area supplied by the middle cutaneous branch. Furthermore, the clinical application was reported. A local pedicled flap containing the middle cutaneous branch was used to repair the soft tissue defects of the foot in 7 patients, and free cutaneous graft was used to repair the skin defects of the fingers in 6 patients. RESULTS The results showed that the medical plantar artery gave off 3 cutaneous branches to supply the medial aspect of the foot, among which the middle branch was the largest one and anastomosed with the other two branches. The skin flaps used clinically were all survived completely. CONCLUSION Medial plantar cutaneous graft had a reliable blood supply, and it’s one of the best choice in repairing small to middle sized skin defects of the foot and the fingers.
