We confirmed the prcathesis should beimplanted in the space between the nasal boneand the complex. The reason for complicationhappened in this approach was that...
ObjectiveTo explore advantages and feasibility of a new prosthesis implantation method after breast cancer surgery by reacquaint breast anatomy. MethodsThe clinicopathologic data of patients with breast cancer were retrospectively collected. The patients underwent the breast cancer surgery and prosthesis implantation with cricoid breast ligament in the Xuzhou Cancer Hospital from January 1, 2021 to May 30, 2023. ResultsA total of 10 patients were collected, with age ranging from 31 to 59 years old. Three patients received postoperative analgesia, 2 patients occurred infection, 1 patient occurred fat liquefaction. All patients did not experience capsular contracture, flap necrosis, or removal of the prosthesis. Two patients had sentinel lymph node metastasis. All patients followed-up 3 to 24 months after surgery. The BREAST-Q questionnaire was used to assess the quality of life and satisfaction after surgery, 3 patients were very satisfied, 5 were satisfied, and 2 were basically satisfied. ConclusionFrom the results of limited cases analysis in this study, it is safe and feasible to implant the prosthesis with cricoid breast ligament in selected patients after breast cancer surgery.
Objective To study the operative effect and complication of the prosthesis replacement of the proximal humerus with malignant tumor. Methods From October 1998 to August 2003, the prosthesis replacement was performed to treat the proximal femur with malignant tumor in 4 patients, including 2 patients with osteosarcoma (Enneking staging,ⅡA) and 2 patients with giancell tumor of the bone (ⅡA,ⅡB). By the International Society of Limb Salvage(ISOLS) criterion, the 2 cases of osteosarcoma were preoperatively scored as 4 and 5 points, and 2 cases of giant cell tumor of the bone were scored as 9 and 11 points. The patients’ psychological conditions as well as their limb pain, shape, locality, activity, and function werealso observed. Results The follow-up for 24-58 months (mean, 44 months) showed that there was no local recurrence or infection in all the patients except onepatient who had the loosening of the screws for the fixation 17 months after operation and had no treatment. After operation, all the patients had a better postoperative extention angle from 22° to 41°(mean, 25°), bending angle from 29° to 80°（mean, 35°）, abduction angle from 5° to 28°, and circumgyrate angle from 15° to 22° in their shoulder joints. However, the shoulder joint function was still unstable to some extent and the joints had a decreased strength. By the criterion formulated by the ISOLS, the postoperative score for assessing the 2 patientswith osteosarcoma was increased by 16 points when compared with the preoperative score; the score for the 2 patients with giant cell tumor of the bone was increased by 9.5 points.Conclusion The prosthesis replacement to treat the malignant tumor of the proximal humerus is the good method of choice and has a good therapeutic result; however, there are more complications and so the method should be cautiously employed in the clinical practice.
Objective To discuss the effectiveness of breast reconstruction with dual plane prosthesis implantation or anterior pectoralis prosthesis implantation under endoscopy by using prospective comparative study, in order to provide a reference for clinical surgical selection. Methods A total of 54 female patients with breast cancer admitted between January 2023 and December 2023 and met the selection criteria were selected as research subjects. According to the random number table, 54 patients were divided into trial group and control group with 27 cases in each. The patients in the trial group and control group were treated with dual plane prosthesis implantation and anterior pectoralis prosthesis implantation for breast reconstruction after glandular resection under endoscopy, respectively. There was no significant difference between the two groups (P>0.05) in the terms of age, body mass index, affected side, breast clinical stages, molecular typing, disease duration, breast volume of healthy side, breast ptosis of affected side, and preoperative Breast-Q score (social mental health, sexual health, breast satisfaction, chest somatic health). The operation-related indicators (operation time, total volume of drainage within 7 days after operation, extubation time, and hospital stay), occurrence of complications, breast reconstruction efficacy related indicators (transverse and longitudinal distance difference), and the pre- and post-operative differences (change values) of Breast-Q scores for each item were compared between the two groups. Results There was no significant difference in operation time, total volume of drainage within 7 days after operation, extubation time, and hospital stay between the two groups (P>0.05). All patients of the two groups were followed up 3-12 months (mean, 6.3 months). Three patients (11.11%) in trial group and 5 patients (18.52%) in control group experienced complications, and there was no significant difference in the occurrence of complications (P>0.05). At 7 days after operation, the transverse and longitudinal distance differences were significantly less in trial group than in control group (P<0.05). The Breast-Q scores of the two groups at 7 days after operation were significantly higher in all items than those before operation (P<0.05), but there was no significant difference in all change values between the two groups (P>0.05). ConclusionFor patients with breast cancer, comparison of breast reconstruction with anterior pectoralis prosthesis implantation, breast reconstruction with dual plane prosthesis implantation has better breast reconstruction effectiveness and higher safety.
Objective To probe a satisfactory surgical management of the limbsalvage for osteogenic malignant tumors around the knees. Methods From January1989 to December 2001, 42 patients (19 males and 18 females, aged 12-46) with osteogenic malignant tumors around the knees underwent surgical management of the limb salvage, including prosthesis replacement, allogenous bone grafting, and bone cement with adriamycin filled. Based on the pathological examination, osteosarcoma was found in 11 patients, synoviosarcoma in 4 patients, malignant fibrous histiocytoma in 3 patients, and giant cell tumor of the bone in 19 patients. All the patients underwent neoadjuvant chemotherapy for 1-2 courses before operatioexcept the patients with giant cell tumor of the bone. The patients underwent prosthesis replacement, allogenous bone grafting, bone cement with adriamycin filled, and postoperative chemotherapy. By the Enneking evaluating system, the patients were assessed on their reconstructed limb functions after the reconstructive operation for the musculoskeleta malignant tumors. Of the patients, 37 were followed up after operation. Results According to the follow-up for 3-11 years (mean, 5.6 years) in the 37 patients, 2 patients had recurrence and metastasis of the tumor, and died 3 and 4 years after operation, respectively. One patient underwent amputation of the limb for local recurrence of the tumor. One patient had amputation of the limb for the preoperative radiotherapy and the infection and necrosis of the operative wound after the limb-salvage surgery. Two patients had amputation of the limb for the rejection of the allogenous bone graft and theformation of the fistula.Thirty-one patients had good wound healing andgood functions of the limb. The results were evaluated by the Enneking evaluating system as follows: excellent in 7 patients, good in 14, fair in 10, and poor in 6. Conclusion Making an early diagnosis, recognizing the operative indication, choosing the operative method, and performing the preoperative and postoperative chemotherapy and/or radiotherapy are the keys to achieving an ideal limb-salvage surgery for osteogenic malignant tumors around the knees.
OBJECTIVE To review the history and current status of total wrist arthroplasty. METHODS The original articles about wrist arthroplasty in recent years were reviewed. RESULTS The properties of wrist prosthesis of different generations were reviewed, with the emphasis on the prosthesis design and biomechanical behaviours. The surgical techniques, complications and salvage procedures were also discussed. CONCLUSION Although wrist arthrodesis is highly successful in treating the end-stage wrist arthritis, total wrist arthroplasty using well-designed prosthesis remains an alternative for the patients with special demands of hand functions.
ObjectiveTo evaluate the effectiveness of anatomic femoral component prosthesis for severe development dysplasia of the hip (DDH) in total hip arthroplasty (THA). MethodsBetween September 2009 and September 2013, 48 patients (51 hips) with severe DDH underwent THA with cementless anatomic femoral component prosthesis. There were 5 males (5 hips) and 43 females (46 hips) with an average age of 51 years (range, 28-67 years). The left hip was involved in 25 cases, the right hip in 20 cases, and bilateral hips in 3 cases. There were 39 cases (44 hips) of Crowe type Ⅲ and 9 cases (7 hips) of Crowe type ⅠV. The visual analogue scale (VAS) score was 5.72±1.84, and Harris score was 41.66±4.87 at preoperation. All patients had leg discrepancy with a length difference of (4.31±0.84) cm. ResultsThe duration of surgery was 59-110 minutes (mean, 78.6 minutes), and the hospitalization days were 6-20 days (mean, 12.3 days). All patients obtained primary healing of incision without wound related complications of swelling, effusion, and infection. Two patients were found to have intramuscular venous thrombosis. All patients were followed up 10-54 months (mean, 29 months). Limp was observed at the early stage after operation in 9 patients and disappeared after 1 year, the other patients had normal gait. The VAS score 1.46±0.47, Harris score 88.66±3.48, and the leg length difference (1.15±0.33) cm at last follow-up all showed significant differences when compared with the preoperative values (P<0.05). No prosthesis loosening or subsidence, heterotopic ossification, dislocation, and infection occurred. ConclusionAnatomic femoral component prosthesis for severe DDH in THA can relieve pain, and improve the hip joint function and limb discrepancy. Short-term effectiveness was satisfactory, but the long-term effectiveness should still be observed in future.
