While modern surgical techniques have made the surgeon’s task easier, nevertheless it remains unclear which of the two most common techniquesthe measured resection or balanced flexion gap techniquesmore accurately restores femoral component rotation. This study aimed to compare the femoral rotation produced by these two surgical techniques and the relationship between the femoral rotation and coronal tibial alignments.This retrospective cohort study compared 20 posterior stabilized Anatomic Modular Knee (AMK), aligned using a measured resection technique to 20 mobile bearing Low Contact Stress knee (LCS) aligned using a balanced flexion gap referencing system. Long leg standing x-rays and CT scans of knees were used to measure rotation of the femoral component in the axial plane and tibial alignment in the coronal plane. Results: Average femoral component rotations were 2.98 (SD 3.21) degrees and 2.26 (SD 1.20) degrees for the AMK and LCS, respectively. Tibial component alignments were 0.66 (SD 1.94) degrees valgus and 0.4 (SD 1.09) degrees valgus for the AMK and LCS, respectively. These differences were not statistically significant. Conclusion: There were no statistically significant differences in femoral rotation between the two referencing systems. However, the balanced flexion gap method had a narrower range of implant rotational position. No statistically significant relationship was found between femoral rotation and tibial alignment in either system.","PeriodicalId":322846,"journal":{"name":"The Internet Journal of Orthopedic Surgery","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128506798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Habib, Sudesh Sharma, Masood Habib","doi":"10.5580/28cf","DOIUrl":"https://doi.org/10.5580/28cf","url":null,"abstract":"Background: The tibia is the most commonly fractured bone of all the long bones in the body. In-spite of advances in treatment, fractures of tibia still pose a challenge to the orthopaedic surgeon as to their best method of management. Vulnerability of soft tissues and increased incidence of open fractures further complicates these fractures. Minimally invasive percutaneous plate osteosynthesis is one of the modalities of treatment of tibial diaphyseal fractures which causes minimal disturbance of blood supply and preserves the soft tissues around the fracture site. The aim of our study is to show the results of treatment of tibial diaphyseal fractures using MIPPO technique. Patients and methods: Our study included fifty patients with tibial diaphyseal fractures treated with locking compression plate using MIPPO technique. Fourteen patients had associated skeletal injuries. Ten patients had a type one open fracture. Results: All the fractures united at an average of 22.25 weeks. Forty patients (80%) were pain free, six patients (12%) had occasional pain (no limitation of activities) and four patients (8%) had persistent pain with limitation of daily activities. 46 (88%) had excellent or good results and 4 (8%) had poor results. 4 (8%) patients had delayed union and 1(2%) patient developed superficial skin infection, 6 patients (12%) had a palpable hardware and 3 patients (6%) had ankle stiffness.Conclusion: Minimally invasive plate osteosynthesis is a good and safe technique for treatment of tibial diaphyseal fractures providing fracture healing, rapid functional recovery, with minimal soft tissue damage and preservation of blood supply. It is a reliable approach for the management of tibial diaphyseal fractures with proper indications.","PeriodicalId":322846,"journal":{"name":"The Internet Journal of Orthopedic Surgery","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124883696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The appearance resembles an acute infection and is often mistaken for more common hand sequela (3, 13-15,) even when a primary malignant tumor is known. Acrometastases usually develop late in the course of tumor seeding and are associated with a low life expectancy (5). Treatment is palliative with focus on pain relief and improvement of hand function in order to maintain the patients independency. For distal lesions, amputation is the treatment of choice. Suggested treatment for proximal metastases consists of systemic therapy and/or radiation with or without local excision. A radical resection requires amputation of a significant part or the hand (3, 6). The concept of palliative tumor surgery with local tumor resection and bridging of the defect with a cement osteosynthesis is widely accepted for the long bones. This case presents an attempt to resect a painful acrometastasis to the proximal phalanx and provide stability by a composite cement arthrodesis of the metacarpophalangeal joint in order to avoid amputation.","PeriodicalId":322846,"journal":{"name":"The Internet Journal of Orthopedic Surgery","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124184229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Defects are usually filled with autogenous bone graft. Alternatively hydroxyapatite crystals may be used to overcome the donor site morbidity of autogenous bone grafting. Our purpose of study was to depict the fate of hydroxyapatite crystals in these lesions. Method : We treated 5 cases of giant cell tumour, 5 cases of simple bone cyst and 2 case of aneurysmal bone cyst, who presented with lytic lesion of long bones, by curettage alone and application of hydroxyapatite crystals. The patients were selected according to inclusion and exclusion criteria’s. These patients were followed up for 36 month. Radiographic evaluation was done according to IRWIN grading, stage I (obvious margins), stage II (hazy margins) and stage III (obvious incorporation). Observation: We found no rejection of implanted hydroxyapatite crystals. In maximum of 13 month all cases show incorporation of hydroxyapatite crystals to host bone. Out of 12 cases final Irwin grading was III in 10 cases(83.33%) and II in 2(16.67%) cases. Absorption of hydroxyapatite crystals is very slow process, even in three year follow up, very little hydroxyapatite crystals was absorbed. Union and remodelling of bone in pathological fracture was normal. There was no collapse of graft on weight bearing. During followup period, haematological and blood biochemical parameters stayed within normal limit. No long term complication seen in any case with hydroxyapatite crystals except recurrence of tumour seen in two cases. Conclusion: Hydroxyapatite crystals are slowly absorbed by body. Bone ingrowth and bone formation around the hydroxyapatite crystals are excellent. Hydroxyapatite crystals have great biological safety, good biocompatibility & good bone conduction.","PeriodicalId":322846,"journal":{"name":"The Internet Journal of Orthopedic Surgery","volume":"33 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113937183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No patient had neurovascular (NV) symptoms prior to manipulation under anaesthetic (MUA). No patients required admission for complications related to ketamine sedation following MUA. Fracture angulation improved significantly. 4 patients required admission for repeat MUA +/- K-wire stabilisation/open reduction internal fixation (ORIF) due to failure of reduction. There were no neurological/vascular complications on discharge. All patients had made excellent functional recovery on discharge. Manipulation of paediatric forearm fractures under ketamine is safe. Excellent radiological and clinical results were noted for the majority of patients. Most requiring further operative intervention were all completely displaced on radiographs in two orthogonal views. We therefore highlight a fracture pattern that is not suitable for MUA in the absence of portable x-ray.","PeriodicalId":322846,"journal":{"name":"The Internet Journal of Orthopedic Surgery","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130531027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
