  • MINI EXTERNAL FIXATION DEVICE FOR COMMINUTED OPEN FRACTURES OF METACARPAL AND PHALANGE

    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.

  • PROGRESS OF METACARPAL AND PHALANGE LENGTHENING

    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.

  • A COMPARATIVE STUDY ON TWO DIFFERENT ABSORBABLE INTRAMEDULLARY NAILS IN TREATING METACARPAL AND PHALANX FRACTURES

    Objective To study the effect of two different absorbable intramedullary nails in treatment of metacarpal and phalanx fractures.Methods From January 2002 to December 2002, open reduction and internal fixation were done with two different absorbable intramedullary nails in 60 cases of metacarpal and phalanx fractures( 52 cases of open fractures and 8 cases of closed fractures). The fracture locations were metacarpal in 24 cases, proximal phalanx in 22 casesand media phalanx in 14 cases. The emergency operation was performed in 47 cases, selective operation in 13 cases.Out of 60 patients, 24 were treated with intramedullary nails of poly-DL-lactic acid (PDLLA) (PDLLA group), 36 with intramedullary wire of PDLLA composed of chitosan(PDLLA+chitosan group). Results In the PDLLA group(n=24), the rejection occurred in 8 cases 3-4 weeks after operation. PDLLA nails were taken out in 6 of the 8 cases after 5-10 days of operation and bone healing was achieved 2 months after re-fixation by Kirschner wire; therejection subsided in the other 2 cases after 25 days of conservative treatment, and bone fracture healed after 14 weeks. No rejection was observed with primary healing in the other 16 cases of the PDLLA group. In PDLLA + chitosan group(n=36), the rejection occurred in 1 case 19 days after operation, but therejection subsided after 3 days of conservative treatment.No rejection was observed in the other 35 cases with primary healing. All patients were followed up 4-11 monthswith an average of 6 months. No rejection was observed and bone healing was achieved during the follow-up. The time of bone healing was 6-16 weeks(8 weeks onaverage). There was statistically significant difference in the curative resultbetween two groups(Plt;0.05). Conclusion Intramedullary nail of PDLLAwas verysuitable to fix fractures of metacarpal and phalanx. During the degradation of PDLLA, the acidic products can cause rejection. When PDLLA mixed with chitosan,PDLLA can not only strengthen the intensity but also neutralize the acidity. So the rejection can be decreased.PDLLA intramedullary nails composed of chitosan were better than PDLLA intramedullary nails in clinical treatment of metacarpal and phalanx fractures.

  • DIAGNOSIS AND TREATMENT OF COMPLICATIONS ASSOCIATED WITH CLOSED MULTI FRACTURES IN METACARPALS

    Objective To pay attention to the diagnosis and treatment of the complications associated with closed multifractures in metacarpals. Methods From 1997 to 2000, out of 382 patients with closed multi-fractures in metacarpals, 12 had complications. In 7 cases of fractures at the second , third , fourth and fifth metacarpal shaft, complicated by acute compartment syndrome in hand, compartmental fascia were incised for decompress; open reduction and internal fixation were performed. In 4 cases of fractures at the metacarpal base, complicated by acute carpal tunnel syndrome, the fracture was reduced and fixed without transection of the transverse carpal ligament. In 1 case of fracture at metacarpalbase, complicated by direct contusion of the median nerve, the fracture was reduced without treatment of the median nerve. Results All patients were followed up for 3 months. Fracture healed 46 weeks postoperatively. No claw deformity anddysfunction of the median nerve occurred. The arc of motion of the proximal interphalangeal and distal interphalangeal joints were normal.Conclusion During fracture reduction, we should pay attention to the complications associated with closed multi-fractures at metacarpal to decrease hand malfunction.

  • THE APPLICATION OF W SHAPE WIRE TO THE EARLY TREATMENT FOR THE METACARPAL BONY LOSS FROM WAR INJURY

    From 1989 to 1991, eighteen cases of the metacarpal bony loss from war injury were treated in Africa. Their ages ranged from 17~56 years old. Fourteen patients were injuried from gunshot; another four were injuried from blast. All of the eighteen were performed with W shape wire, and these can be done as early as 4~16 hours after the initial injuries. The author introduced the way of making W wire and the important points of the surgical technics. We suggest that the key to the successful operation is the good debridement,covertage of wound with healthy soft tissue and the good drainage.

    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.

  • Effectiveness on treatment of metacarpal avulsion fracture with Kirschner wire buckling combined with bone fixation

    Objective To summarize the effectiveness of Kirschner wire buckling combined with bone fixation in the treatment of metacarpal avulsion fracture. Methods The clinical data of 35 patients of metacarpal avulsion fracture admitted between March 2017 and June 2022 were retrospectively analyzed. There were 22 males and 13 females; the age ranged from 20 to 55 years, with an average of 31.6 years. There were 17 cases of the second metacarpal avulsion fracture, 6 cases of the fourth metacarpal avulsion fracture, and 12 cases of the fifth metacarpal avulsion fracture. The causes of injury included 21 cases of strangulation, 8 cases of sprain, and 6 cases of sports injury. X-ray film examination showed that the size of the avulsion fracture of metacarpal bone ranged from 0.30 cm×0.20 cm to 0.55 cm×0.45 cm. The total active motion (TAM) of the injured finger before operation was (154.00±17.38)°. The time from injury to operation was 3-10 days, with an average of 5.8 days. Follow-up regularly after operation, X-ray film and CT examination were performed to evaluate fracture healing and TAM of injured finger was measured. The finger function was evaluated by the trial standard of upper limb function evaluation of Hand Surgery Society of Chinese Medical Association. Results All the incisions healed by first intention. All 35 patients were followed up 9-36 months, with an average of 28 months. All metacarpal avulsion fractures achieved bony healing, and the healing time was 4-6 weeks, with an average of 4.8 weeks. The metacarpophalangeal joint of the patient was stable, without stiffness, and the flexion and extension activities were good. At last follow-up, the TAM of the injured finger reached (261.88±6.23)°, which was significantly different from that before operation (t=−35.351, P<0.001). The finger function was evaluated according to the trial standard of upper limb function evaluation of the Society of Hand Surgery of Chinese Medical Association, and 33 cases were excellent and 2 cases were good, with an excellent and good rate of 100%. Conclusion The treatment of metacarpal avulsion fracture with Kirschner wire buckling combined with bone fixation has the advantages of less trauma, firm fixation, and less interference to the soft tissue around metacarpophalangeal joints, which is a good alternative method for the metacarpal avulsion fracture.
