Objective To explore the effectiveness of mini external fixation device for comminuted open fractures of the metacarpal and phalange. Methods Between October 2009 and April 2011, 33 patients with comminuted open fractures of the metacarpal and phalange were treated with mini external fixation device. There were 25 males and 8 females, aged from 21 to 62 years with an average of 25.5 years. Of 33 cases, 7 were rated as Gustilo type II and 26 as Gustilo type IIIA; 20 cases were diagnosed as having simple metacarpal and phalangeal comminuted fractures and 13 cases as having combined interphalangeal or metacarpophalangeal joint fractures. Partial or complete rupture of tendon was observed in 18 cases. The time between injury and operation was 2-8 hours (mean, 3.7 hours). After one stage debridement and reduction, fracture was fixed with mini external fixation device. Results Primary healing of incision was obtained in 30 cases and no pin hole infection was found. Incision infection occurred in 3 cases and leaded to nonunion. Nonunion also occured in 2 cases of simple metacarpal and phalangeal fractures. The mean follow-up was 8 months (range, 6 months to 1 year). X-ray films showed fracture healing in 13 cases after 8 weeks (8 cases of simple metacarpal and phalangeal fractures and 5 cases of combined interphalangeal or metacarpophalangeal joint fractures), in 12 cases after 12 weeks (7 cases of simple metacarpal and phalangeal fractures and 5 cases of interphalangeal or metacarpophalangeal joint fractures), and in 3 cases of simple metacarpal and phalangeal fractures after 6 months. After removing the mini external fixation device and functional exercise, 3 cases of simple metacarpal and phalangeal comminuted fractures and 4 cases of combined interphalangeal or metacarpophalangeal joint fractures still had joint stiffness, but had no finger rotation and alignment deformity or chronic pain. According to the measurement of total active movement for 28 patients who obtained fracture healing, the results were excellent in 7 cases, good in 12 cases, fair in 5 cases, and poor in 4 cases, the excellent and good rate was 67.9%. Conclusion The mini external fixation device is a good technique for comminuted open fractures of metacarpal and phalange. In patients having comminuted open fractures with interphalangeal or metacarpophalangeal joint fracture, the results are fair or poor.
Objective To review the methods of metacarpal and phalange lengthening and to point out the problems at present as well as to predict the trend of development in the field. Methods Domestic and abroad l iterature concerning the methods of metacarpal and phalange lengthening in recent years was reviewed extensively and thoroughly analyzed. Results At present, there are many methods to treat the short finger disabil ity, but the methods of metacarpal and phalange lengthening have an advantage, which include closed osteotomy lengthening, callus-lengthening, and modified Il izarovmethod. Each surgical method has its advantages and l imitations. However, the part of osteotomy, the length and speed, and the postoperative compl ications etc. have been disputed. Conclusion The modified Il izarov method has the advantages of simple operation, minimal invasion, and less compl ications, but the long-term results of each treatment method are unknown and need more further studies.
ObjectiveTo discuss the clinical curative effect of internal fixation for metacarpal and phalanx fractures using stainless steel mini-plate and the early rehabilitation. MethodsThe study included 47 cases treated from January 2006 to June 2011, including 25 cases of 72 phalangeal fractures, 17 cases of 43 metacarpal fractures, and 5 cases of 23 complex metacarpal and phalangeal fractures. All the patients underwent open reduction and micro-plate internal fixation. Three days after surgery, passive function training was initiated. Patients accompanied with blood vessel damage began the training one week later. The training was carried out based on the early rehabilitation schedule. ResultsPrimary healing occurred in all the 47 cases. There was one case of broken plate because of crashing. Postoperative follow-up lasted for 4 to 10 months, and the fractures were healed in 138 lesions. X-ray examination showed that bone union took place at week 8 to 11 averaging at 10. According to the functional evaluation of total autive movement scales, the excellent and good rate was 83.0%. ConclusionThe stainless steel mini-plate in the treatment of metacarpal and phalangeal fractures has a firm fixation and is advantageous. Combined with early rehabilitation training, it can maximize the recovery of hand function with satisfactory clinical results.
