Impact of unplanned excision on prognosis of patients with extremity soft tissue sarcoma

Unplanned excision of soft tissue sarcomas (STSs) outside comprehensive tumor management centers necessitates the need for wide reexcision to achieve adequate margins. We retrospectively reviewed medical records of 135 patients with STS operated at our hospital with the goal of examining outcomes, in terms of local recurrence (LR) and metastasis rate (MR), of reexcision following unplanned excision of STS and comparing results with those of first-time planned surgery. Eighty-four patients had their first-time surgery and 51 patients had come to us following unplanned excision at prereferral hospital. Mean age of all patients was 41.8 ± 21.9 years. The LR and MR was 14.3% and 8.3%, respectively, in patients undergoing first resection, whereas it was 21.4% and 13.7%, respectively, in patients undergoing revision surgery. Average duration from previous unplanned excision was 8 months. Twelve patients were referred immediately after excised specimen revealed STS, while 39 patients presented after evident local recurrence. Wide reexcision was attempted in 48 patients while three patients need amputation. Adjuvant radiotherapy was administered in all patients undergoing limb-sparing surgery. Ten patients needed adjuvant chemotherapy.We conclude that wide reexcision of STS has poorer outcomes compared to planned excision. Therefore, patients with soft tissue masses should be managed by multidisciplinary oncology team at specialized cancer centers

Operative management of patients with non-spinal metastatic bone disease. Does it actually improve quality of life?

Abstract OBJECTIVE: To determine the survival rate and functional outcome of skeletal stabilisation in patients with metastatic bone disease. METHODS: The retrospective study was conducted at Aga Khan University Hospital, Karachi, and comprised data of patients with non-spinalmetastatic bone disease managed surgically from January 2002 to December 2010. All patients had been managed by experienced orthopaedic, oncology and multidisciplinary teams. Patients managed by non-oncologic orthopaedic surgeons were excluded. The prognostic influence of clinical, pathological and treatment variables on Musculoskeletal Tumour Society score, range of motion, local complications and death rate were measured. SPSS 19 was used for statistical analysis. RESULTS: Of the 49 patients whose records were included in the study, 21(42.9%) males and 28(57.1%) females with an overall median age of 59 years. Most common primary tumour site was breast in 15(3.8%) followed by lungs in 11(22.4%), Open reduction and internal fixation was the mpst commonly used procedure in 18(36.7%) patients. Mean duration of follow-up was 30.20±29.2 SD months (range: 10-48 months). The median patient survival was 23 months. 23% patients have superficial surgical site infection. Mean Musculoskeletal Tumour Society score was 23.73±14.3 SD. CONCLUSIONS: The results confirm the principle that surgery for metastatic disease is done primarily to improve quality of life and ambulation status, and to alleviate pain

Treatment of tibial diaphyseal fractures with closed flexible intramedullary ender nails: 39 fractures followed for a period of two to seven years

Abstract OBJECTIVE: To assess the efficacy of flexible intramedullary Ender nails for the treatment of tibial diaphyseal. MATERIALS AND METHODS: This is a retrospective review of patients treated with the Ender Nail for both open and closed tibial shaft fractures. Between January 1989 and December 1994, 43 fractures were treated with these nails. The configuration of each fracture was determined using the Orthopedic Trauma Association classification and the extent of soft tissue damage was assessed using the Gustilo and Anderson\u27s classification. Four patients were excluded from the study due to inadequate follow-up. There were 27 closed and 12 open fractures. RESULTS: The average time to union in 34 out of 39 fractures was 17 weeks. Delayed union and malunion occurred in two patients each and superficial wound infection in 1 patient. Nonunion occurred in 5 fractures that were all located in the distal 1/3 of the tibial diaphysis. We attribute this high rate of non-union to a poor rotational control on the distal fragment by these nails. CONCLUSIONS: The Ender nails provide effective fixation for the OTA stable class of tibial fractures, where they produce good axial and rotational stability by virtue of their three-point fixation. Rotational and angular stability should be improved by a supplementary cast immobilization for fractures with unstable configuration and those located in the distal third of the diaphysis

Hip reconstruction osteotomy by Ilizarov method as a salvage option for abnormal hip joints

Hip joint instability can be secondary to congenital hip pathologies like developmental dysplasia (DDH) or acquired such as sequel of infective or neoplastic process. An unstable hip is usually associated with loss of bone from the proximal femur, proximal migration of the femur, lower-extremity length discrepancy, abnormal gait, and pain. In this case series of 37 patients coming to our institution between May 2005 and December 2011, we report our results in treatment of unstable hip joint by hip reconstruction osteotomy using the Ilizarov method and apparatus. This includes an acute valgus and extension osteotomy of the proximal femur combined with gradual varus and distraction (if required) for realignment and lengthening at a second, more distal, femoral osteotomy. 18 males and 19 females participated in the study. There were 17 patients with DDH, 12 with sequelae of septic arthritis, 2 with tuberculous arthritis, 4 with posttraumatic arthritis, and 2 with focal proximal femoral deficiency. Outcomes were evaluated by using Harris Hip Scoring system. At the mean follow-up of 37 months, Harris Hip Score had significantly improved in all patients. To conclude, illizarov hip reconstruction can successfully improve Trendelenburg’s gait. It supports the pelvis and simultaneously restores knee alignment and corrects lower-extremity length discrepancy (LLD)

Asymptomatic urinary tract infection: Cause of postoperative wound infection

bstract OBJECTIVE: To determine the rate of urinary tract infection in patients given incomplete treatment before undergoing hip fracture surgery. METHODS: The descriptive case series was conducted at Aga Khan University Hospital, Karachi, From October 25, 2012 to April 24, 2013. 84 postmenopausal women having hip fracture along with asymptomatic urinary tract infection. The infection was treated incompletely and postoperatively wound infection rate was determined. The SPSS version 17 was used to analyze the data. RESULTS: The overall mean age of the 84 patients in the study was 63.57+10.34 years. Overall, 14(16.7%) patients had wound infection after orthopaedic implant surgery for hip fracture. CONCLUSIONS: There was a high occurrence of wound infection after hip implant surgery in patients having preoperative asymptomaticurinary tract infection who were treated incompletely

Acetabular morphometry for determining hip dysplasia in the Singaporean population

Abstract PURPOSE: To assess and evaluate the usefulness of 7 morphological measurements of the acetabulum in establishing the prevalence of acetabular dysplasia in the Singaporean population. METHODS: Standardised plain anteroposterior radiographs of 522 hip joints of 261 asymptomatic patients (mean age, 60 years; range, 16-99 years) were evaluated. The 7 morphological measurements were centre-edge angle, acetabular angle, depth-to-width ratio, roof obliquity, extrusion index, lateral subluxation, and peak-to-edge distance. RESULTS: 19 (7.3%) patients were acetabular dysplastic (centre-edge angle of \u3c20 \u3edegrees). The mean centre-edge angle was 31.2 degrees (range, 5-52 degrees), acetabular angle 39.46 degrees (range, 10-58 degrees), depth-to-width ratio 0.32, roof obliquity 7.86 degrees, extrusion index 0.18, lateral subluxation 9.9 mm, and the peak-to-edge distance 15.65 mm. CONCLUSION: Centre-edge angle was the most useful measurement and correlated significantly with acetabular angle, extrusion index, peak-to-edge distance, and roof obliquity. These preliminary results show a relatively higher rate (7.3%) of acetabular dysplasia in the Singaporean population, compared with other similar but larger Asian studies performed in Hong Kong (1.1%) and Korea (1.8%)

Operative treatment of bilateral hip dislocation in children with arthrogryposis multiplex congenita

Abstract PURPOSE: Arthrogryposis multiplex congenita (AMC) is a rare syndrome with multiple joint contractures. It is commonly believed that bilaterally dislocated hips associated with joint contractures should not be reduced, because movement is satisfactory, while open reduction leads to poor results. This report presents our experience with surgical management of bilateral dislocation of hips in children with AMC. METHODS: During the period 1990 to 2000, we performed open reduction on 8 hips of 4 children with AMC. The mean age at surgery was 23 months (range, 5-48 months). Open reduction and capsular plication without any bony procedure were performed in 4 hips (2 patients). De-rotation and varus osteotomy of the femur was performed in 4 hips, and Salter osteotomy of the innominate bone in 2 hips. The average acetabular index was 44 degrees, and the mean centreedge angle was -41 degrees preoperatively. RESULTS: The average follow-up period was 4 years (range, 2-9 years). The average acetabular index and centre-edge angle were 19 and 18 degrees, respectively at the time of last follow-up. All children could walk without support. One child required re-opening for redislocation of hip joint. The clinical results were good in 6 hips and fair in 2 hips, according to Severin\u27s and McKay\u27s classifications. CONCLUSION: Our experience shows that open reduction for bilateral dislocation of hips in children with AMC is a suitable option with generally good results. Surgery performed at earlier age gives the best functional outcome

Arthroscopic repair of meniscal tears with inside-out technique

Objective: To review the clinical results of arthroscopic meniscal repair and to identify factors that may affect the outcome. Methods: A total of 15 arthroscopic meniscal repairs with inside-out in 14 patients over a 7-year period were evaluated retrospectively. The mean age was 41.2 +/- 11.5 years with a range of 26-64 years. Eleven patients underwent repair for medial meniscal tear, two patients for lateral meniscus and one patient for both in the same knee. All patients were functionally evaluated by Lysholm functional knee scores over an average follow-up of 1 year and 5 months (range: 0.5-7 years). Results: The mean Lysholm score was 84 out of a maximum of 100. Functional outcome was excellent in 6 patients, good in 5, fair in 2 and poor in one patient. The patient with poor outcome was young with a chronic tear; she had concomitant ipsi-lateral radiculopathy and also had signs of reflex sympathetic dystrophy. One 64 year old patient with fair outcome developed a post-operative flexion contracture of 15 degrees. She also had moderate osteoarthritis of the medial compartment. One patient developed saphenous nerve neuralgia which was relieved spontaneously after a few months. Conclusion: All patients with excellent results were relatively younger with an acute tear. Elderly patients with concomitant osteoarthritis of the knee joint did not have a satisfactory outcome even if the tear was acute
