Objective To introduce a modified method to correct type I and type II cup ear and to evaluate the effectiveness. Methods Between May 2006 and November 2011, 23 patients with type I or type II cup ear (27 ears, type I in 6 ears and type II in 21 ears according to Tanzer’s criteria) were treated. There were 14 males and 9 females with an average age of 10 years (range, 7-16 years). The unilateral ear was involved in 19 cases and bilateral ears in 4 cases. The main clinical manifestations included the flat helix and scapha and ptosis of upper 1/3 auricle. The arc incision was adopted in the auriculocephalic angle, elevation of the dis-clothing-like flap in the front and rear of the auricular cartilage, relocation of the craniofacial initiation site of the scapha and the cavity of auricular concha, correction of deformational auricular cartilage and reconstruction of smooth helix, antihelix, superior and inferior antihelix crus. Results All the incisions healed by first intention without any hematoma, postoperative infection, or flap necrosis. All patients were followed up 9 months-6 years (median, 36 months). No auricle ptosis, deformity contour, or atrophy was observed. The structure of the helix, scapha, and antihelix were clear, natural, and excellent. The scars at the local site were limited and unconspicuous. Conclusion Modified method can almost correct all the anatomic defects of cup ear. It is an ideal method to treat type I and type II cup ear.
Objective To improve the surgical procedure to correctpectus carinatum. Methods From 1990 to 2003, 9 patients with pectus carinatum were treated, whose ages ranged from 3 years and 6 months to 16 years. The conventional operation was performed on 4 patients, the modified procedure on 5 patients. The modified procedure included: ①the shortening rib periosteum was not sutured transversally；② the corrected position of the sternum was stabilized with the metal strut. Results In 4 patients corrected by the conventional procedure, the sternum depression as pectus excavatum occurred in 1 case five years postoperatively. The results were satisfactory in 5 patients corrected by the modified procedure. The reconstructed thorax was symmetrical, without bulging or dimpling of sternum and costal cartilage. Conclusion The improvement of operative method isreasonable and effective in correcting pectus carinatum.
Over a two year period, four patients of pectus carinatum received surgical correction at our hospital. All patients were followed up for 6 months to 1 year. The operative results were satisfactory but one required revision with additional resection of bilateral second cartilage for the persistent malformation. The clinical characteristics, operative techniques and indications for operative treatment were discussed.
ObjectiveTo study the causes and treatment of postoperative deviation secondary to thumb duplication resection. MethodsBetween February 2007 and June 2013,32 cases (33 thumbs) of postoperative deviation secondary to thumb duplication resection were treated,and the clinical data were retrospectively analyzed.There were 13 males and 19 females,aged 2-34 years (median,8 years).The left thumbs were involved in 7 cases,the right thumbs in 24 cases,and bilateral thumbs in 1 case.Of 33 thumbs,2 were rated as type Ⅱ,4 as type Ⅲ,10 as type IV,7 as type V,and 10 as type VⅡ according to Wassel classification.The average time between duplicated thumb resection and admission was 6.5 years (range,1-29 years).Nine thumbs only had ulnar deviation of the metacarpophalangeal (MP) joint;8 thumbs only had radial deviation of the interphalangeal (IP) joint;10 thumbs only had ulnar deviation of the IP joint;and 6 thumbs had ulnar deviation of the MP joint combined with radial deviation of the IP joint.The mean deviation degree of the MP joint was 32.3°(range,20-40°),and the mean deviation degree of the IP joint was 42.5°(range,30-110°).Operation methods were chosen specially according to the deformity,including remnant bone or cartilage resection,restoring normal alignment,and soft tissue balance. ResultsAll wounds got first stage healing and there was no complication associated with operation.Postoperative follow-up period ranged from 6 to 70 months (mean,34 months).The skeleton alignment of the thumbs was improved on the X-ray images;all osteotomy got union at 5-10 weeks (mean,6 weeks).Deviation was completely corrected in 31 thumbs;the preoperative deviation degree was too large to correct completely in 2 thumbs with a postoperative deviation degree of 10°.The motion degree was similar to that at preoperation in 13 thumbs;the motion degree decreased in 20 thumbs,which did not affect the function of the thumbs.Nineteen cases (20 thumbs) were followed more than 2 years,there was no recurrence of deviation and all thumbs developed well,but the size of affected thumb was smaller than that of the contralateral side in 14 cases (14 thumbs). ConclusionGetting good result and preventing postoperative deviation for thumb duplication resection acquires appropriate preoperative design,reconstruction of the insertion of the abductor pollicis brevis,transposition of the flexor and extensor pollicis longus insertion,and essential osteotomy play important roles in preventing postoperative deviation after thumb duplication resection.Individualized treatment plan for deviation should be made according to the degree and the cause of deviation.
Objective To summarize and analyze the characteristics and treatment strategies of post-traumatic lower limb deformity based on QIN Sihe Orthopaedic Surgery Database. Methods A clinical data of 837 patients with post-traumatic lower limb deformities treated by orthopaedic surgery between May 25, 1978 and December 31, 2020 in QIN Sihe Orthopaedic Surgery Database were analyzed retrospectively. The information of the patient’s gender, age at the time of surgery, region of origin, cause of trauma, deformity side, orthopedic surgery related information (operation time, location, type, and fixation method after operation) were summarized and analyzed. ResultsAll patients came from 32 provinces, municipalities, autonomous regions, and Taiwan in China. Among them, 551 cases (65.83%) were male and 286 cases (34.17%) were female. The age of the patients at the time of surgery was 3-84 years old, with an average of 27.6 years old, and the most patients were 16-45 years old (559 cases, 66.78%). The main cause of trauma was traffic accident injury (639 cases, 76.34%). The deformity mainly involved unilateral limbs, including 394 cases (47.07%) on the left side and 376 cases (44.92%) on the right side. The most patients were admitted between 2008 and 2017, accounting for 53.05% (444/837). All patients were operated on one or more sites (1 048 sites), among which ankle and toe surgery were the most, accounting for 48.38% (507/1 048). The patients received 1204 surgeries including tendon lengthening and soft tissue contracture release, et al. Orthopedic surgery combined with bone external fixation was used in 624 cases (467 cases of Ilizarov external fixation and 157 cases of combined external fixation), and plaster or brace external fixation was used in 213 cases. Conclusion Post-traumatic lower extremity deformity patients have a large proportion of males, with a wide geographical distribution, involving various parts of the lower extremities, and most commonly in the foot and ankle. Orthopedic surgery combined with bone external fixation (Ilizarov technique) is the main methods for correction and functional reconstruction of post-traumatic lower limb deformity.
