From 1979 to 1994, reparative and recons tructive surgery were used to repair the war injuries of skins, bones, blood vessels and nerves of the limbs in 800 cases. A systematic clinical study was carried out. Many new operative methods were used and the results of treatment were good. Innovations and modifications were made in technique. In 120 cases of warin juries having soft tissues defects including skin and muscles, various tissue transplantations were used with the hope to accomplish onestaged repair of the defect and reconstruction of motor function of muscle. To those infections of bone and joint in war injuries, following early eradication of infected focus, transplantation of musculocutaneous flap or omental graft was immediately carried out with the aim to obtain primary healing of the wound. In the treatment of bone defects from war wounds with loss of skin and muscles, the vascularized skeletocutaneous graft was used. In the treatment of 150 cases of injury of peripheral nerve from forearms, the result of good to fair rated 68.8 percent for upper extremity and that for lower extremity, it was 62.2 percent. Following the early repair of 500 cases of injury of peripheral blood vessels, the patency rate of the blood vessel was 90 percent. The result following by pass vascular graft in the treatment of forearms injury of blood vessels even with very poor local condition was still very successful.
Objective To analyze the data of external fixation instruments (including Ilizarov instruments) used by QIN Sihe orthopaedic surgical team in the treatment of limb deformities in the past 30 years, and to explore the indications for the application of modern external fixation techniques in the correction of limb deformities and individual device configuration selection strategy. Methods According to QIN Sihe orthopaedic surgical team, the use of external fixator between January 1988 and December 2017 was analyzed retrospectively. The total use of external fixation and the proportion of different external fixators were analyzed in gender, different operation time, different age, different parts, and different diseases. Results External fixators were used in 8 113 patients, 69 of them were used simultaneously in both lower extremity surgery, so 8 182 external fixators were used. Among them, there were 4 725 (57.74%) combined external fixators, 3 388 (41.41%) Ilizarov circle fixators, 64 (0.78%) single arm external fixators (including Orthofix), 5 (0.06%) Taylor space external fixators. There were 4 487 males (55.31%) and 3 626 females (44.69%). According to the analysis of different time periods, the number of external fixators increased year by year, and the number of applications increased after 2000. The main age of the patients was 11-30 years old, of which 1 819 sets (22.23%) were used at the age of 21-25 years. The use of the external fixator covered almost all parts of the limbs, with the ankle and toe areas being the most common, reaching 4 664 sets (57.00%), and the upper extremities the least, with 152 sets (1.86%). The 8 113 cases covered more than a dozen disciplines and more than 150 kinds of diseases. The top 5 diseases were poliomyelitis sequelae, cerebral palsy, deformity of lower extremity after spina bifida, traumatic sequelae, and congenital equinovarus foot. Conclusion Ilizarov technique has been widely used in extremity deformity, disability, and complicated orthopedic diseases caused by vascular, lymphoid, nerve, skin, endocrine, and other diseases. The indication of operation is far beyond the scope of orthopedics. The domestic external fixator and its mounting tools can basically meet the requirements of various treatments. The technique of external fixation has entered a new era of tension tissue regeneration under stress control, natural repair of tissue trauma and deformity, and reconstruction of limb function.
ObjectiveTo establish a forecasting model for inpatient cases of pediatric limb fractures and predict the trend of its variation.MethodsAccording to inpatient cases of pediatric limb fractures from January 2013 to December 2018, this paper analyzed its characteristics and established the seasonal auto-regressive integrated moving average (SARIMA) model to make a short-term quantitative forecast.ResultsA total of 4 451 patients, involving 2 861 males and 1 590 females were included. The ratio of males to females was 1.8 to 1, and the average age was 5.655. There was a significant difference in age distribution between males and females (χ2=44.363, P<0.001). The inpatient cases of pediatric limb fractures were recorded monthly, with predominant peak annually, from April to June and September to October, respectively. Using the data of the training set from January 2013 to May 2018, a SARIMA model of SARIMA (0,1,1)(0,1,1)12 model (white noise test, P>0.05) was identified to make short-term forecast for the prediction set from June 2018 to November 2018, with RMSE=8.110, MAPE=9.386, and the relative error between the predicted value and the actual value ranged from 1.61% to 8.06%.ConclusionsCompared with the actual cases, the SARIMA model fits well with good short-term prediction accuracy, and it can help provide reliable data support for a scientific forecast for the inpatient cases of pediatric limb fractures.
To report the diagnosis methods and cl inical treatment effects of blood vessel trunk damage in l imbs. Methods From January 2001 to June 2006, 72 patients with vascular injury in l imbs were treated. There were 50 males and 22 females, aged from 5-60 years (median 39 years) and including 44 cases of open injury and 28 cases of closed injury.The locations were subclavian artery in 1, femoral artery in 23, popl iteal artery in 20, radia artery and ulna artery in 12, brachial artery in 11, axilary artery in 3 and anterior and posterior tibia artery in 2. The disease course was 30 minutes to 27 days. Injured arteries were repaired by suturing directly in 3 cases, by end-end anastomosis in 39 cases and by saphenous transplantation in 30 cases. The length of transplant veins was 3 cm to 8 cm. Results In 72 cases, 67 survived and 5 were given amputation. Fortyeight cases were followed up 6 months to 5 years. The blood flow rate and the diameter of blood vessel on the affected l imbs were not different from that of normal l imbs by colorful Doppler blood flow monitor. Forty cases recovered satisfactory l imb function. Eight cases had different degrees of dysfunction, of them, four cases received functional reconstructive operation, and the function and appearance were improved. Conclusion To investigate the mechanism and situation of injury, to examine patients carefully and analyze comprehensively are the key points of making earl ier diagnosis for branch blood vessel damage; microsurgical repair of the injured blood vessel is the assurance of the blood flow rate. For the blood vessel above elbow and knee injured and lacked blood supply more than 4 hours and fascia syndrome, earl ier opening the fascia cavity is the effective methods to recover the function of the l imbs and to avoid disabil ity.
Objective To investigate the application and effect of the crossbridge vascular anastomosis free flap transplantation for tissue defects of extremities. Methods From May 1982 to November 2005, 110 cases of tissue defects of extremities were treated with cross-bridgevascular anastomosis free tissue transplantation. Of 110 patitents, 80 were male and 30 were female with a median age of 30 years(5 to 54 years). Tissue defects were caused by traffic accidents (59 cases), machine injuries (32 cases) and mangled injuries (19 cases). The locations were the forearms in 2 cases and the legs in 108 cases. And 69 cases had simple soft tissue defects, 6 cases had simple bone defects, and 35 cases had complicated defects. The length of bone defectranged from 5 cm to 19 cm and the area of soft tissue defect ranged from 6 cm×10 cm to 15 cm×35 cm. The graft tissue included latissimus dorsi musculocutaneous flap, vastus anterolateral flap,cutaneous fibula flap, osseous fibula flap, and cutaneous iliac flap. The cross-bridge of the two lower extremities wasperformed in 106 cases, the cross-bridge of the two upper extremities in 2 cass, and the crossbridge of the upper-lower extremities in 2 cases. The compoite tissue transplantation was used if the graft tissues were two or more. The wounds of donor site was directly sutured in 67 cases, and partly sutured with skingrafting in 43 cases. Results Vascular crisis occurred in 9 cases. Vascular crisis was relieved in 5 cases and grafting tissues was survival after exploring the vessel; 4 cases failed. The graft tissue was survival in 101 cases, and the survivalrate was 96.4%. The follow-up time was 4 months to 22 years with an average of 6.3 years. Graft bone healed and mean healing time was 4 months. The flap appearance was satisfactory and extremity function was restored to normal. One case became necrosis in the edge of the flap and cured by debridement, dressing and skingrafting, the other got primary healing at 2-3 weeks after operation. Conclusion The application of the cross-bridge vascular anastomosis free tissue transplantation for tissue defects of extremities is an effective method, when extremities have no vessel anastomosed.

Objective To summarize the cl inical effect of anterolateral thigh pedicle or free perforator flap in repairing soft tissue defect in the extremities. Methods From March 2000 to January 2009, 32 cases of soft tissue defect were treated with pedicle or free anterolateral thigh perforator flap. There were 30 males and 2 females with an median age of28 years (4-53 years). Soft tissue defects included left radial side in 3 cases, the left lateral elbow in 1 case, knee in 5 cases, calf in 14 cases, dorsal is pedis in 5 cases, and planta pedis in 4 cases. The defect area ranged from 9 cm × 6 cm to 15 cm × 13 cm. Nine cases compl icated by bone defect and 1 case by radial nerve defect. The time from injury to hospital ization was 1 hourto 4 months (mean 5 days). Defects in 27 cases were repaired by anterolateral thigh perforator flap, simultaneously combined with transplantation with the second toe in 1 case, with sural nerve using arterial ized small saphenous vein in 1 case, nd with fibular or il ium in 4 cases. Defects in other 5 cases were repaired with flaps pedicled with superior lateral genicular artery. Neuroanastomosis was performed in 14 cases of the flaps. The size of the flaps ranged from 10 cm × 8 cm to 16 cm × 15 cm. Skin defects at donor site were repaired with spl it thickness skin graft or sutured directly. Results All patients were followed up from 8 months to 9 years with an average of 18 months. The flaps survived well and the wounds healed by first intention in 29 cases, 3 flaps necrosed and cured after symptomatic management. Skin graft at donor site survived completely in 9 cases. The color and texture and thickness of the flaps were similar to those of recipient site. After 6 months, the sensation of the flaps recovered to grade S3-4 in 14 patients whose cutaneous nerve were anastomosed, partial recovery was observed in other patients. In 4 patients receiving transplantation of fibular or il ium, the bony heal ing was achieved within 4 to 6 months. No obvious dysfunction was found at the donor site. Conclusion The pedicle anterolateral thigh perforator flap is long and thick with constant location. Anastomosis or transferring is easy to perform. It can provide big area and feel ing recovery by nerve anastomosis. It is an effective method to repair soft tissue defect of the extremities.
Objective To investigate the clinical outcome of sensory reconstruction about the functional perforator flap for repairing the complex defects on the limbs. Methods A retrospective analysis was conducted on 21 patients with limb complex defects admitted between March 2018 and January 2023. There were 12 males and 9 females, with a median age of 36 years (range, 19-62 years). The wounds were on the upper limbs (hands) in 13 cases and the lower limbs (feet) in 8 cases. Five patients with tumor/scar, and the left defects after en-bloc resection of the tumor lesion and scar were repaired immediately. The remaining 16 cases were acute/chronic wounds, undergoing the emergent debridement and vacuum sealing drainage placement, and the left defects were repaired with flaps during second-stage operation. The size of the defects ranged from 5.5 cm×4.5 cm to 17.0 cm×12.0 cm. The donor sites were located on the thoracic and back in 4 cases, the anterior lateral thigh in 6 cases, and the feet in 11 cases. All flaps were functional perforator flaps with sensory nerve. The donor sites were closed directly or repaired with skin grafting. At last follow-up, the sensation of flap and the muscle strength of recipient site were evaluated according to the British Medical Research Council (BMRC) sensory grading (S0-S4) and muscle strength grading (M0-M5) criteria. Results Twenty flaps survived completely without significant complication, and partial edge necrosis was observed in 1 flap, which healed after the debridement and skin grafting. The donor and recipient sites healed by first intention. All patients were followed up 10-18 months (mean, 12 months). At last follow-up, the flaps with satisfactory shape and soft texture were observed, and no abnormal hair growth or pigmentation occurred. The sensation of flap was evaluated as S1 in 2 cases, S2 in 7, S3 in 9, and S4 in 3. The muscle strength of recipient site was evaluated as M2 in 4 cases, M3 in 9, M4 in 5, and M5 in 3. Only linear scars were left at the donor site. Conclusion The functional perforator flap with sensory nerve is beneficial for early sensation reconstruction for repairing the complex defects on the limbs, and could reconstruct the functional subunit structure defect in one stage. The short-term functional follow-up results are satisfactory.
