Abstract Postburn deformities, including hypertrophic scars, scar contracture and defect or deformity of tissue or organ, are the commonest disorders in plastic surgery. It is also difficult to deal with. If the diformity involved multiple organs, oftentimes the teatmentis very difficult because the material for repair is limited and the donorsite usually could not provide adequate amount of skin for repair. Since 1978,2496 cases of various postburn deformities were admitted. In this article, theoptimal time to operate was discussed. The use of flap transfer and soft tissueexpander was described. Prolonged traction in the treatment of severe contracture of large joint was also described.
Objective To introduce a method of the surgicalcorrectionof Poland’s syndrome in children. Methods From May 1990 to May 2002, 3 female children with Poland’s syndrome were treated. One child of 12 years old with defects of the right second and third costal cartilages, pectoralis major and pectoralis minor underwent repair of chest wall with graft of autologous costal cartilage from left sixth costal cartilage and transfer of the latissimus dorsi flap. The other 2 children, 3 and 16 years old, with defects of theleft second, third and fourth costal cartilages, pectoralis major and pectoralis minor underwent graft of autogenous costal cartilage from the right sixth costal cartilage and implant of Dexon mesh. Results Three patients were followed up 1, 7 and 10 years postoperatively, respectively.The contour of chest wall in 3 patients were improved. The functions of the chest, back and upper limbs in the deformitis side were good and the growth and development of thechildren were normal during follow-up postoperatively.Conclusion The congenital deformities of multiple systems and parts in the body are involved in Poland’s syndrome so that it is necessary to make a proper surgical plan according to the extent of lesions for a satisfactory result.
【Abstract】 Objective To investigate the effectiveness of pedicled sternocleidomastoid muscle flap in repairing defect after parotidectomy by comparing with direct suture. Methods The clinical data were retrospectively analyzed, which were from 73 patients with parotid tumor undergoing parotidectomy between January 2002 and April 2010. After parotidectomy, defects were repaired with pedicled sternocleidomastoid muscle flap in 38 cases (flap group) and with direct suture in 35 cases (control group). There was no significant difference in gender, age, disease duration, tumor location and size between 2 groups (P gt; 0.05). Meanwhile the complications, such as local introcession deformity, Frey’s syndrome and parotid gland fistula were observed. Results In flap group, the flaps were all alive and incisions healed by first intention; in control group, all incisions healed by first intention. All patients were followed up 6-98 months and no tumor recurred. There was significant difference in local introcession deformity between 2 groups (χ2=53.202, P=0.000). The parotid gland fistula was found in 1 case (2.6%) of the flap group and in 8 cases (22.8%) of the control group, Frey’s syndrome was found 1 case (2.6%) of the flap group and in 20 cases (57.1%) of the control group, showing significant differences between 2 groups (P lt; 0.05). Conclusion The use of pedicled sternocleidomastoid muscle flap for defect repair after parotidectomy can avoid the complications of local introcession deformity, Frey’s syndrome, and parotid gland fistula.
Objective To review the progress in clinical and biomechanical study on soft tissue reconstruction of adult-acquired flatfoot deformity (AAFD). Methods The recent original articles of soft tissue repair and tendon transfer for AAFD were extensively reviewed. Results The soft tissue procedures for AAFD can be divided into two components: static restoration of medial column stability and dynamic reconstruction of the posterior tibial tendon. The most important static structure to be repaired for AAFD is the spring ligament. On the other hand, various methods can be used for dynamic reconstruction. The flexor digitorum longus transfer is widely used, but results of biomechanical studies do not support the advantage of this method. For patients having normal function of the posterior tibial muscle, the Cobb procedure may be more suitable. Conclusion The soft tissue reconstruction procedures of AAFD should be chosen individually based on the stage and type of the deformity.
ObjectiveTo preliminarily investigate morghological changes of rabbits reshaping ear cartilage assisted by microdissection needle and explore feasibility of new therapy for ear deformity.MethodsThe bilateral ears of 5 male New Zealand rabbits (aged, 5-6 months) were fixed maintaining the curvature and randomly divided into 2 groups (5 ears in each group). The ears were stimulated by microdissection needle in experimental group and were not treated with stimulation in control group. The skin reaction in the experimental group was observed immediately and at 4 weeks after stimulation. Then, the fixtures were removed at 4 weeks, and the shapes of the ears were observed. The cartilages were harvested from the ears to examined morphological changes after HE staining, and measured the chondrocyte layer thickness.ResultsAll rabbits survived until the end of the experiment. The skin has healed completely after 4 weeks in experimental group. After removing fixtures, the ears in the two groups all maintained certain forms momentarily; while 24 hours later, the ears in the control group mostly recovered original form, and the ears in the experimental group still maintained certain molding form until 8 weeks. HE staining showed there were smooth cartilage and uniform distribution of cells in the control group; the matrix staining was basically consistent; and the skin was normal appearance with epidermis, dermis, and cartilage of normal aspect. But the proliferation of chondrocyte with more layers of cells were observed in the experimental group. In addition, there were degeneration and injury of cartilage cells and connective tissue with necrotic cells and inflammatory cells at needle insertion sites. The chondrocyte layer thickness was (385.714±2.027) μm in the control group and (1 594.732±1.872) μm in the experimental group, there was significant difference between the two groups (t=–759.059, P=0.000).ConclusionRabbit ear cartilage can be effectively reshaped by microdissection needle. Proliferation of chondrocyte and changes in matrix can be found during the reshaping process.
OBJECTIVE: To evaluate the effectiveness of the Bridle procedure in treatment of foot deformity in children with slight cerebral spastic paralysis. METHODS: From February 1993 to April 1999, 32 cases with 57 deformed feet, due to slight cerebral spastic paralysis, which included 20 males and 12 females, ranging from 4 to 14 years old, were reported after 6 to 74 months’ follow-up, averaging 38 months. Bilateral feet were involved in 25 cases and unilateral feet involved in 7 cases. The deformities in all feet, including 26 feet of acroceph-foot deformity in 15 cases, 13 equinovarus deformity in 8 cases and 18 scissors gait deformity in 9 cases, were treated by Bridle procedure, followed by temporal external fixation of long-leg plaster splint for 6 to 8 weeks. RESULTS: Clinical observation revealed complete and permanent correction of deformity in 48 out of all 57 feet (84.2%), reoccurrence of deformity in 7 feet (12.3%), and occurrence of valgus deformity in 2 feet (3.5%). No joint stiffness was observed. CONCLUSION: The Bridle procedure is an easily performed operation and effective in the treatment of foot deformity in children with slight cerebral spastic paralysis
Various tissue flaps were used in the repair of 255 cases of the wounds from severe deep burns and cicatricial deformities. The types of flaps used included: 6 kinds of myocutaneous flaps in 54 cases, 10 kinds of axial cutaneous flaps in 50cases, 7 kinds of fasciocutaneous flaps in 44 cases, pedicled subcutaneous tissues flaps in 12 cases, pedicled thin skin flaps in 54 cases, subdermal vascular networks cutaneous flaps in 38 cases, and free skin flaps with arter ialization of vein flap, retrograd island cutaneous flap with great or small saphaneous vein, in each. The survival rate from the transplantation was 99.2 per cent, and the rate of primary healing was 94.5 per cent. According to the time interval between the injury and operation and the conditions of the wounds, the patients were divided into acute, infected and selective cases, and the rate of primary healing was 93.0 per cent, 91.6 per cent and 97.9 per cent, respectively. The selection of the types of flap to be used and the attentions to be taken dueing operation were discussed.
ObjectiveTo investigate the short-term effectiveness of INBONETM Ⅱ total ankle prosthesis arthroplasty in the treatment of moderate to severe varus-type ankle arthritis. MethodsThe clinical and radiographic data of patients with moderate to severe varus-type ankle arthritis, who were admitted between May 2017 and November 2021 and treated with total ankle arthroplasty (TAA) using INBONETM Ⅱ prosthesis, was retrospectively analyzed. A total of 58 patients (58 ankles) met the selection criteria and were included in the study. Among them, there were 24 males and 34 females, with an average age of 62.6 years (range, 41-85 years). According to the preoperative tibiotalar angle (TTA), the patients were divided into a moderate varus group (group A, TTA 5°-15°, n=34) and a severe varus group (group B, TTA>15°, n=24). There was no significant difference in gender, side, etiology, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, ankle dorsiflexion, plantarflexion, and total range of motion, and tibial lateral surface angle (TLS) between the two groups (P>0.05). Yet the patients in group A were younger than group B, the degrees of oesteoarthritis (Takakura stage) and ankle pain [visual analogue scale (VAS) score] were milder, and the TTA, talar tilt angle (TT), hindfoot alignment angle (HAA) were smaller while the tibial articular surface angle (TAS) was larger, showing significant differences (P<0.05). The pre- and post-operative VAS score, AOFAS score, the occurrence of early and late complications, the radiographic parameters of the ankle (TTA, TAS, TT, HAA, TLS), ankle dorsiflexion, plantarflexion, and total range of motion were recorded and compared. ResultsAll patients were followed up 19-72 months, with an average of 38.9 months. Compared with the preoperative data, the VAS score of all patients significantly decreased (P<0.05); the AOFAS score, ankle dorsiflexion range of motion, and total range of motion significantly increased (P<0.05); and the TTA, TAS, TT, HAA, and TLS significantly improved at last follow-up (P<0.05); but there was no significant difference in plantarflexion range of motion (P>0.05). Early complications occurred in 13 patients, and only 1 patient underwent revision surgery due to a larger size of the talar component. At last follow-up, there was no significant difference in the difference of clinical parameters before and after operation between the two groups (P>0.05); there was a significant difference in the difference of other radiographic parameters (P<0.05) except TLS. No significant difference in the incidence of complications between the two groups was found (P>0.05). ConclusionTAA using the INBONETM Ⅱtotal ankle prosthesis is an effective treatment for moderate or severe varus-type ankle arthritis, and good clinical and radiographic results can be obtained. Correcting bony deformities and balancing soft tissue are the keys to successful surgery.
To explore related factors of cubital tunnel syndrome caused by cubitus valgus deformity so as to provide theoretical basis for the cl inical treatment. Methods Between June 2002 and September 2008, 40 patients with cubital tunnel syndrome caused by cubitus valgus deformity underwent anterior subcutaneous ulnar transposition. Related factors wasanalysed through logistic regression analysis using scoring standard recommended by Yokohama City University. Results All 40 patients were followed up 27.5 months on average (range, 12-75 months). The duration of cubitus valgus deformity, cubitus valgus deformity angle, and the duration of paraesthesia and muscular atrophy were identified as related factors for ulnar neuropathy and the odds ratios were 1.005 (P=0.045), 9.374 (P=0.000), and 4.358 (P=0.010), respectively. The related prognosis factors were duration of paraesthesia and muscular atrophy, deformity angle, and age at surgery, with odds ratios of 8.489 (P=0.000), 2.802 (P=0.030), and 4.611 (P=0.031), respectively. Conclusion Related factors for ulnar neuropathy are durations of cubitus valgus deformity, cubitus valgus deformity angle, and duration of paraesthesia and muscular atrophy. Related factors for prognosis include age at surgery, cubitus valgus deformity angle, and duration of muscular atrophy. Early anterior subcutaneous ulnar transposition should be performed in patients with cubital tunnel syndrome caused by cubitus valgus deformity
Objective To assess the efficacy of the extra long scapular-lateral thoracic-il ioinguinal siamese flap to repair the contracture deformity of perineal scar caused by burn and to discuss its characteristics. Methods From January2008 to August 2009, 9 patients with contracture deformity of perineal scar after deep II degree to III degree burn were treated. There were 7 males and 2 females aged from 22 to 54 years (35.4 years on average). The course of disease ranged from 8 months to 5 years. All cases had central type of perineal scar. Among the cases, 3 cases were compl icated by abdominal scar, 4 cases by legs scar, and 2 cases by abdominal and legs scar. Scar ulcer was observed in 2 cases. The opening-closing angle of bilateral lower extremities was (29.4 ± 8.8)°. And anus could not expose entirely so that squatting and rel ieving the bowels were difficult in 6 cases. Defect areas after scar resection ranged from 20 cm × 6 cm to 28 cm × 8 cm. The size of extra long scapular-lateral thoracic-il ioinguinal siamese flap ranged from 35 cm × 12 cm to 58 cm × 15 cm. The donor sites were sutured directly. Results Bl ister and necrosis occurred in 1 case and was cured after dressing changed, and others flaps survived with wounds primary heal ing. Incision at donor site healed by first intention. All cases were followed up 6-12 months. The perineal function improved and the partial deformities were corrected. The opening-closing angle of bilateral lower extremities increased to (75.6 ± 11.3)°, showing significant difference between pre- and post-operation (P lt; 0.05). The functions of squatting and rel ieving the bowels recovered well. The perineal scar adhesion recurred in 2 cases after 6 months of operation and were cured after scar resectionand expanding flaps transposition. Conclusion In view of large donating region, great facil ity for transposition, stableand sufficient blood supply, reutil ization as expanded flap, it was an effective treatment and a beneficial trial by applying the transposition of the extra long scapular-lateral thoracic-il ioinguinal siamese flap for contracture deformity of perineal scar caused by burn.
