Objective To assess the outcomes of pedicle subtration osteotomy and short-segment pedicle screw internal fixation in kyphosisdeformity. Methods From June 2001 to November 2003, 16 cases of kyphosis deformity were treated with pedicle subtration osteotomy and short-segment pedicle screw internal fixation, including 11 males and 5 females and aging 24-51 years. The kyphosis deformity was caused by ankylosing spondylitis in 12 cases, old lumbothoracic fracturedislocation in 2 cases, and vertebral dysplasia in 2 cases. The disease course was 7-25 years with an average of 12.8years. The whole spine radiographs were taken pre-and postoperatively. The sagittal balance was assessed by measuring thoracic kyphosis angle, lumbar lordosis angle, acrohorizontal angle and distance between posterosuperior point of S1and the vertical line. The clinical outcomes were assessed by Bridwell-Dewald scale for spinal disorders. Results The mean follow-up period was25.6 months. The mean bleeding was 1 100 ml. Satisfactory bone graft healing was achieved at final follow-up. Complications were paralytic intestinal obstruction in 1 case, dura laceration in 1 case, and temporary lower limb paralysis in 2 cases. Final follow-up radiograph showed an increase in lumbar lordosis angle from 9.6±16.4° to 42.6±14.3°(P＜0.05), whereas thoracic kyphosis angle remained relative stable. The distance between posterosuperior point of S1 and the vertical line was decreased from 97.5±45.6 mm to 10.7±9.6 mm(P＜0.05). Satisfactory clinical outcome was achieved by evaluating the changes of pain, social and working status. Conclusion Pedicle subtraction osteotomy and short-segment pedicle screw internal fixation is effective for correction of kyphosis deformity.
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.
Objective To investigate the effectiveness of lateral condyle sliding osteotomy (LCSO) in total knee arthroplasty (TKA) for the treatment of lateral femoral bowing deformity. Methods The clinical data of 17 patients with lateral femoral bowing deformity treated by LCSO during TKA between July 2018 and July 2020 was retrospectively analysed. There were 3 males and 14 females, with an average of 63.2 years (range, 58-68 years). The etiology of lateral femoral bowing deformity included 12 cases of femoral developmental deformity and 5 cases of femoral fracture malunion. Kellgren-Lawrence classification of knee osteoarthritis was 4 cases of grade Ⅲ and 13 cases of grade Ⅳ. The preoperative hip-knee shaft was 9.5°-12.5° (mean, 10.94°). The disease duration was 3-25 years (mean, 15.1 years). The mechanical lateral distal femur angle (mLDFA), hip-knee-ankle angle (HKA), and mechanical axis deviation (MAD) of the distal femur were measured before operation and at last follow-up to evaluate the correction of extra-articular deformities in the joints and the recovery of mechanical force lines of the lower extremities. The knee society score (KSS) knee score and function score, visual analogue scale (VAS) score, knee joint range of motion (ROM) were used to evaluate effectiveness. The knee varus/valgus stress test and osteotomy healing by X-ray films were performed to evaluate the joint stability and the safety of LCSO. Results All incisions of the patients healed by first intention after operation, and there was no early postoperative complication such as infection of the incision and deep vein thrombosis of the lower extremities. All 17 patients were followed up 12-36 months, with an average of 23.9 months. The osteotomy slices all achieved bony healing, and the healing time was 2-5 months, with an average of 3.1 months. After operation, the knee varus/valgus stress tests were negative, and there was no relaxation and rupture of the lateral collateral ligament, instability of the knee joint, loosening, revision and infection of the prosthesis occurred. At last follow-up, mLDFA, HKA, MAD, knee ROM, VAS score, KSS knee score and function score significantly improved when compared with preoperative ones (P<0.05). Conclusion LCSO is effective and safe in TKA with lateral femoral bowing deformity. Extra-articular deformities are corrected intra-articularly. The mechanical force line and joint balance of the lower extremities can be restored simultaneously in an operation.
Objective To investigate the effectiveness of sequential plate internal fixation in the correction of Madelung deformity after ulnar osteotomy and shortening. Methods The clinical data of 13 patients with Madelung deformity admitted between September 2015 and July 2021 were retrospectively analyzed. There were 5 males and 8 females with an average age of 18.3 years ranging from 17 to 23 years. The disease duration ranged from 12 to 24 months, with an average of 17 months. Three cases had a clear history of trauma. All patients had external radial deviation deformity and limited movement of the ulnar deviation, and the ulnar impact pain was significant during ulnar deviation movement; 9 patients had limited wrist joint supination movement, and the supination movement was normal. In the first stage, ulnar osteotomy and shortening combined with external fixator were used to correct wrist deformity in 13 patients. After operation, bone transfer was performed 6 times per day, with adjustments made every 4 hours, which was 1 mm per day. After the osteotomy was in place, the ulnar plate internal fixation was performed to reconstruct the ulnar stability in the second stage. The Cooney wrist joint score was used to assess the pain, function, range of motion, flexion and extension range of motion, and grip strength of the wrist joint before operation and before the removal of internal fixator. The subjective feeling and appearance satisfaction of patients were recorded. ResultsAfter the second-stage operation, all the 13 patients were followed up 10-22 months, with an average of 15 months. The deformity of wrist joint disappeared after operation, and the flexion, extension, and ulnar deviation were basically normal. There was no complication such as ulnar impingement sign, nonunion or infection. Wrist function, pain, and range of motion were significantly improved after operation, except for 1 patient who had no significant improvement in rotation and pain. The ulnar internal fixator was removed at 10-18 months after the second-stage operation. The scores of pain, function, range of motion, flexion and extension range of motion, and grip strength in the Cooney wrist score before removal of internal fixator significantly improved when compared with those before operation (P<0.05). Subjective and appearance satisfaction of patients were excellent in 9 cases, good in 3 cases, and fair in 1 case. ConclusionUlnar osteotomy and shortening with sequential plate internal fixation for correction of Madelung deformity, with mild postoperative pain, can effectively avoid bone nonunion, improve wrist joint function, and have significant effectiveness.
In order to correct the dysfunction of head and neck with scar contracture, since 1980, sixty-two cases were undertaken the operation by using local skin flap to repair the soft tissue defect after scar resection. The skin flaps included pedicled delto-thoracic skin flap in 26 cases, cervico-thoracic skin flaps in 25 cases, cervico-shoulder flaps in 6 cases, pedicled vascularized extralong delto-thoracic skin flap in 4 cases and free parascapular flap in 1 case. Sixty cases had total survival of the flaps and 2 flaps had partial necrosis. After 1 to 10 years follow-up, the appearance and function of neck were excellent. It was suggested that grafting local skin flap was a good method to treat cicatricial deformity of neck especially using the skin flap with pedicle and vascular bundle.
ObjectiveTo investigate the effectiveness of simultaneous treatment of traumatic calcaneal osteomyelitis and defect deformity with near-arc bone transport by Ilizarov technique.MethodsBetween January 2014 and August 2020, 6 cases of traumatic calcaneal osteomyelitis with defect deformities were treated by simultaneous treatment of near-arc bone transport by Ilizarov technique. The patients were all male; aged from 40 to 61 years (mean, 49.3 years). The disease duration was 2-72 months, with an average of 16.1 months. All patients were traumatic calcaneal osteomyelitis, including 4 cases of falling from height, 1 case of traffic accident injury, and 1 case of crushing injury. The infection affected the talar-heel joint in 4 cases, and the talar-heel joint was fused or partially fused in 2 cases. After the external fixator was removed, the Maryland foot scoring system was used to evaluate the foot function, and the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot function scoring system was used to evaluate the ankle-hindfoot function, and were compared with the preoperative scores.ResultsAll patients were followed up 1.5-26.0 months, with an average of 16.3 months. All incisions healed by first intention, no recurrence of infection occurred, and no surgical intervention such as second-stage bone grafting and fusion was performed. Five cases of calcaneal osteomyelitis with defect deformity underwent one-stage osteotomy and slipped, 1 case of the original bone mass after debridement after infection of calcaneal fractures slipped directly. The bone sliding time was 28-62 days, with an average of 38.7 days; the sliding distance was 3.1-5.2 cm, with an average of 3.6 cm. In 1 patient, due to the short follow-up time, the calcaneal slip bone had not healed, the external fixator had not been removed (not involved in clinical scoring), but the foot shape, reexamination of X-ray films and with frame walking were satisfactory. The time with external fixator was 6-8 months, with an average of 6.5 months in the other 5 cases. After removing the external fixator, the foot returned to three-point weight-bearing, and the longitudinal arch was recovered to varying degrees, and there was no obvious varus valgus. The Maryland score after removal of the external fixator was 80.8±4.7, which was significantly higher than that before operation (33.6±4.3) (t=–35.782, P=0.000), 3 cases were excellent and 2 cases were good; the median AOFAS ankle-hindfoot score was 84, the interquartile range was (79, 86), which was significantly improved when compared with the preoperative score [the median score was 33.5, the interquartile range was (21.3, 37.5)] (Z=–2.023, P=0.043), 4 cases were excellent and 1 case was good. Among them, pain, walking distance, getting rid of walking aids, going up and down stairs, deformity, etc. were significantly improved when compared with preoperative ones. Mobility such as subtalar and hock joints were poor or disappeared.ConclusionSimultaneous treatment of traumatic calcaneal osteomyelitis and defect deformity with near-arc bone transport by Ilizarov technique can optimize the operation method, reduce the number of operations, and try to simulate the original shape of the calcaneus. It is an effective, economical, and novel treatment method.
Objective To investigate the status of nutrition, nutritional support, and postoperative nutrition-related complications in patients with spinal deformity during orthopedic perioperative period. Methods From February to August 2021, patients who underwent spinal orthopedic surgery for spinal deformity in Peking University Third Hospital were collected. A survey was conducted using self-designed questionnaire, including patient’s general information (gender, age, and type of spinal deformity), nutrition-related information (risks of malnutrition, forms of nutritional support), and postoperative nutrition-related complications. Results A total of 39 patients with spinal deformity were enrolled, and 46.2% (18 cases) were at risk of malnutrition. There were a total of 174 times of nutritional support, and 96.0% (167 times) were parenteral nutrition. The patients’ energy intake from nutritional support accounted for 34.41% of the daily goal energy intake averagely. At admission, one day after operation, and at discharge, the prealbumin was (215.51±34.69), (172.85±31.85), and (163.67±29.15) mg/L, respectively, and the hemoglobin was (138.08±15.67), (119.92±18.01), and (117.69±14.76) g/L, respectively, which were significantly lower one day after operation and at discharge than those at admission (P<0.01). The incidence of postoperative nutrition-related complications during hospitalization was 5.1% (2/39). Conclusions Patients undergoing spinal deformity orthopedics are at high risk of overall malnutrition during the perioperative period, their clinical nutritional interventions are mostly based on parenteral nutrition with a single infusion of nutritional preparations, and the nutritional status is not significantly improved. However, the incidence of postoperative nutrition-related complications is low. Standardized nutrition interventions should be strengthened in the future.
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.
