Aims. Patients with soft-tissue sarcoma (STS) who undergo unplanned excision (UE) are reported to have worse outcomes than those who undergo planned excision (PE). However, others have reported that patients who undergo UE may have similar or improved outcomes. These discrepancies are likely to be due to differences in characteristics between the two groups of patients. The aim of the study is to compare patients who underwent UE and PE using propensity score matching, by analyzing data from the Japanese Bone and Soft Tissue Tumor (BSTT) registry. Methods. Data from 2006 to 2016 was obtained from the BSTT registry. Only patients with STS of the limb were included in the study. Patients with distant metastasis at the initial presentation and patients with dermatofibrosarcoma protuberans and well-differentiated liposarcoma were excluded from the study. Results. A total of 4,483 patients with STS of the limb were identified before propensity score matching. There were 355 patients who underwent UE and 4,128 patients who underwent PE. The five-year disease-specific survival (DSS) rate was significantly better in the patients who received additional excision after UE than in those who underwent PE. There was no significant difference in local recurrence-free survival (LRFS) between the two groups. After propensity score matching, a new cohort of 355 patients was created for both PE and UE groups, in which baseline covariates were appropriately balanced. Reconstruction after tumour excision was frequently performed in patients who underwent additional excision after UE. There were no significant differences in DSS and LRFS between the patients who underwent PE and those who had an additional excision after UE. Conclusion. Using propensity score matching, patients with STS of the limb who underwent additional excision after UE did not experience higher mortality and local failure than those who underwent PE. Reconstruction may be necessary when additional excision is performed. Cite this article: Bone Joint J 2021;103-B(12):1809–1814

The accessory navicular (AN) is a separate ossification center for the tuberosity of the navicular that is present in approximately 5–14% of the general population. It produces a firm prominence on the plantar-medial aspect of the midfoot. There may be a co-existent flexible flatfoot, but there is no conclusive evidence of a cause-and-effect relationship between the two conditions. It is usually not symptomatic, and few cases necessitate operative intervention. When symptoms require surgical treatment, excision of the AN, with or without advancement of the posterior tibial tendon, usually is considered. To describe new technique of AN excision and tibialis posterior tendon advancement (TPTA) using a bio-absorbable tenodesis screw and to investigate the outcome of this cohort in comparison to conventional simple excision. Retrospective 2 Cohort study. Single surgeon series from single institution. All patients younger than 18 years from Jan 2000 to Aug 2012 undergoing simple excision (SE) or excision with TPTA were identified from the prospectively collected database. Case notes were reviewed and data regarding demographics, indications for surgery, presence of Pes Planus, time from presentation to surgery, length of follow-up, patient satisfaction and complications were recorded. Pain and functional outcome were measured using Visual Analogue Score (VAS) and patient reported outcome measure- Oxford Ankle Foot Questionnaire- Child and Teenager Version. There were 6 patients in SE group. There were 3 males and 3 females. Mean age at surgery was 13.9 years. Surgical indication was painful swelling in all patients and in addition 1 had pes planus. There were 7 in SE & TPTA group. There were 3 males and 4 females. The mean age at surgery was 13.1 years. Surgical indication was painful swelling in all patients and in addition 1 had hind foot rigidity and 3 had pes planus. Postoperative protocol involved weight bearing with or without cast in SE group and non-weight bearing in cast for 6 weeks in TPA group. All patients reported excellent to good outcome. There were no complications and no reoperations after tendon advancement. In conclusion, based on our study findings, we think AN excision and TP advancement is a safe and effective technique for symptomatic pain relief. It is a novel technique which achieved excellent to good outcome in our series

Aims. Congenital pseudarthrosis of the tibia (CPT) has traditionally been a difficult condition to treat, with high complication rates, including nonunion, refractures, malalignment, and leg length discrepancy. Surgical approaches to treatment of CPT include intramedullary rodding, external fixation, combined intramedullary rodding and external fixation, vascularized fibular graft, and most recently cross-union. The current study aims to compare the outcomes and complication rates of cross-union versus other surgical approaches as an index surgery for the management of CPT. Our hypothesis was that a good index surgery for CPT achieves union and minimizes complications such as refractures and limb length discrepancy. Methods. A multicentre study was conducted involving two institutions in Singapore and China. All patients with CPT who were surgically managed between January 2009 and December 2021 were included. The patients were divided based on their index surgery. Group 1 included patients who underwent excision of hamartoma, cross-union of the tibia and fibula, autogenic iliac bone grafting, and internal fixation for their index surgery. Group 2 included patients who underwent all other surgical procedures for their index surgery, including excision of hamartoma, intramedullary rodding, and/or external fixation, without cross-union of the tibia and fibula. Comparisons of the rates of union, refracture, limb length discrepancy, reoperations, and other complications were performed between the two groups. Results. A total of 36 patients were included in the study. Group 1 comprised 13 patients, while Group 2 comprised 23 patients. The mean age at index surgery was four years (1 to 13). The mean duration of follow-up was 4.85 years (1.75 to 14). All patients in Group 1 achieved bony union at a mean of three months (1.5 to 4), but ten of 23 patients in Group 2 had nonunion of the pseudarthrosis (p = 0.006). None of the patients in Group 1 had a refracture, while seven of 13 patients who achieved bony union in Group 2 suffered a refracture (p = 0.005). None of the patients in Group 1 had a limb length discrepancy of more than 2 cm, while ten of 23 patients in Group 2 have a limb length discrepancy of more than 2 cm (p = 0.006). In Group 1, four of 13 patients had a complication, while 16 of 23 patients in Group 2 had a complication (p = 0.004). Excluding removal of implants, four of 13 patients in Group 1 had to undergo additional surgery, while 18 of 23 patients in Group 2 had to undergo additional surgery following the index surgery (p = 0.011). Conclusion. A good index surgery of excision of hamartoma, cross-union of the tibia and fibula, autogenic iliac bone grafting, and internal fixation for CPT achieves union and minimizes complications such as refractures, limb length discrepancy, and need for additional surgeries

Aims. Clear cell sarcoma (CCS) of soft-tissue is a rare melanocytic subtype of mesenchymal malignancy. The aim of this study was to investigate the clinical and therapeutic factors associated with increased survival, stratified by clinical stage, in order to determine the optimal treatment. Methods. The study was a retrospective analysis involving 117 patients with histologically confirmed CCS, between July 2016 and November 2017, who were enrolled in the Bone and Soft Tissue Tumour Registry in Japan. Results. The five- and ten-year survival rates were 41% (95% confidence interval (CI) 29 to 52) and 37% (95% CI 25 to 49), respectively. On multivariable analysis, the size of the tumour of > 10 cm (p = 0.006), lymph node metastasis at the time of diagnosis (p < 0.001), distant metastases at the time of diagnosis (p < 0.001), and no surgery for the primary tumour (p = 0.019) were independently associated with a poor survival. For N0M0 CCS (n = 68), the development of distant metastases was an independent prognostic factor for survival (early (< 12 months), hazard ratio (HR) 116.78 (95% CI 11.69 to 1,166.50); p < 0.001; late (> 12 months), HR 14.79 (95% CI 1.66 to 131.63); p = 0.016); neoadjuvant/adjuvant chemotherapy (p = 0.895) and/or radiotherapy (p = 0.216) were not significantly associated with survival. The five-year cumulative incidence of local recurrence was 19% (95% CI 8 to 35) and the size of the tumour was significantly associated with an increased rate of local recurrence (p = 0.012). For N1M0 CCS (n = 18), the risk of mortality was significantly lower in patients who underwent surgery for both the primary tumour and lymph node metastases (HR 0.03 (95% CI 0.00 to 0.56); p = 0.020). For M1 CCS (n = 31), excision of the primary tumour was independently associated with better survival (HR 0.26 (95% CI 0.09 to 0.76); p = 0.013). There was no significant difference in survival between the different types of systemic treatment (p = 0.523). Conclusion. Complete excision of the primary tumour and lymph nodes is associated with a better survival in patients with CCS. Systemic treatment appears to provide limited benefits, demonstrating a pressing need for novel systemic agents. Cite this article: Bone Joint J 2023;105-B(11):1216–1225

Aims. Deep surgical site infection (SSI) remains an unsolved problem after hip fracture. Debridement, antibiotic, and implant retention (DAIR) has become a mainstream treatment in elective periprosthetic joint infection; however, evidence for DAIR after infected hip hemiarthroplaty is limited. Methods. Patients who underwent a hemiarthroplasty between March 2007 and August 2018 were reviewed. Multivariable binary logistic regression was performed to identify and adjust for risk factors for SSI, and to identify factors predicting a successful DAIR at one year. Results. A total of 3,966 patients were identified. The overall rate of SSI was 1.7% (51 patients (1.3%) with deep SSI, and 18 (0.45%) with superficial SSI). In all, 50 patients underwent revision surgery for infection (43 with DAIR, and seven with excision arthroplasty). After adjustment for other variables, only concurrent urinary tract infection (odds ratio (OR) 2.78, 95% confidence interval (CI) 1.57 to 4.92; p < 0.001) and increasing delay to theatre for treatment of the fracture (OR 1.31 per day, 95% CI 1.12 to 1.52; p < 0.001) were predictors of developing a SSI, while a cemented arthroplasty was protective (OR 0.54, 95% CI 0.31 to 0.96; p = 0.031). In all, nine patients (20.9%) were alive at one year with a functioning hemiarthroplasty following DAIR, 20 (46.5%) required multiple surgical debridements after an initial DAIR, and 18 were converted to an excision arthroplasty due to persistent infection, with six were alive at one year. The culture of any gram-negative organism reduced success rates to 12.5% (no cases were successful with methicillin-resistant Staphylococcus aureus or Pseudomonas infection). Favourable organisms included Citrobacter and Proteus (100% cure rate). The all-cause mortality at one year after deep SSI was 55.87% versus 24.9% without deep infection. Conclusion. Deep infection remains a devastating complication regardless of the treatment strategy employed. Success rates of DAIR are poor compared to total hip arthroplasty, and should be reserved for favourable organisms in patients able to tolerate multiple surgical procedures.

Aims. The aim of this study was to investigate the outcomes of arthroscopic decompression of calcific tendinitis performed without repairing the rotator cuff defect. Methods. A total of 99 patients who underwent treatment between December 2013 and August 2019 were retrospectively reviewed. Visual analogue scale (VAS) and American Shoulder and Elbow Surgeons (ASES) scores were reviewed pre- and postoperatively according to the location, size, physical characteristics, and radiological features of the calcific deposits. Additionally, the influence of any residual calcific deposits shown on postoperative radiographs was explored. The healing rate of the unrepaired cuff defect was determined by reviewing the 29 patients who had follow-up MRIs. Results. Statistically significant improvement from pre- to postoperation was seen in all VAS and ASES scores for each group, but no statistical differences were seen between the postoperative scores according to the differences in the features of the calcific deposits. When residual calcification was observed postoperatively, the mean ASES and VAS (rest) scores improved significantly to 95.0 (SD 5.6) and 0.0 (SD 0.0), respectively (p = 0.006 and p < 0.001), and did not differ from those who had the complete removal. Of 29 patients who had follow-up MRIs, six (20.7%) showed signs of an interstitial tear. This group’s mean postoperative ASES and VAS (rest) scores improved to excellent levels of 96.0 (SD 3.7) and 0.0 (SD 0.0), respectively, and were similar to those of the 23 patients with normal MRI appearances. Conclusion. Arthroscopic removal of calcific deposits without repairing the rotator cuff defect resulted in significant improvement in function and pain level, regardless of the deposit’s location, size, type, and whether or not complete excision was achieved. Despite leaving the defects unrepaired, in the limited number of patients with follow-up MRIs, 23 of 29 patients (79.3%) showed good healing, and the rest, who had persistent signs of interstitial defects on the MRIs, still had excellent outcomes. The removal of calcific deposits without repairing the cuff defects provided excellent outcomes. Cite this article: Bone Joint J 2023;105-B(6):663–667

Aims. Dead-space management, following dead bone resection, is an important element of successful chronic osteomyelitis treatment. This study compared two different biodegradable antibiotic carriers used for dead-space management, and reviewed clinical and radiological outcomes. All cases underwent single-stage surgery and had a minimum one-year follow-up. Methods. A total of 179 patients received preformed calcium sulphate pellets containing 4% tobramycin (Group OT), and 180 patients had an injectable calcium sulphate/nanocrystalline hydroxyapatite ceramic containing gentamicin (Group CG). Outcome measures were infection recurrence, wound leakage, and subsequent fracture involving the treated segment. Bone-void filling was assessed radiologically at a minimum of six months post-surgery. Results. The median follow-up was 4.6 years (interquartile range (IQR) 3.2 to 5.4; range 1.3 to 10.5) in Group OT compared to 4.9 years (IQR 2.1 to 6.0; range 1.0 to 8.3) in Group CG. The groups had similar defect sizes following excision (both mean 10.9 cm. 3. (1 to 30)). Infection recurrence was higher in Group OT (20/179 (11.2%) vs 8/180 (4.4%), p = 0.019) than Group CG, as was early wound leakage (33/179 (18.4%) vs 18/180 (10.0%), p = 0.024) and subsequent fracture (11/179 (6.1%) vs 1.7% (3/180), p = 0.032). Group OT cases had an odds ratio 2.9-times higher of developing any one of these complications, compared to Group CG (95% confidence interval 1.74 to 4.81, p < 0.001). The mean bone-void healing in Group CG was better than in Group OT, in those with ≥ six-month radiological follow-up (73.9% vs 40.0%, p < 0.001). Conclusion. Local antibiotic carrier choice affects outcome in chronic osteomyelitis surgery. A biphasic injectable carrier with a slower dissolution time was associated with better radiological and clinical outcomes compared to a preformed calcium sulphate pellet carrier.

Aims. The aim of this study was to determine the outcome of all primary total hip arthroplasties (THAs) and their subsequent revision procedures in patients aged under 50 years performed at our institution. Methods. All 1,049 primary THAs which were undertaken in 860 patients aged under 50 years between 1988 and 2018 in our tertiary care institution were included. We used cemented implants in both primary and revision surgery. Impaction bone grafting was used in patients with acetabular or femoral bone defects. Kaplan-Meier analyses were used to determine the survival of primary and revision THA with the endpoint of revision for any reason, and of revision for aseptic loosening. Results. The mean age of the patients at the time of the initial THA was 38.6 years (SD 9.3). The mean follow-up of the THA was 8.7 years (2.0 to 31.5). The rate of survival for all primary THAs, acetabular components only, and femoral components only at 20 years’ follow-up with the endpoint of revision for any reason, was 66.7% (95% confidence interval (CI) 60.5 to 72.2), 69.1% (95% CI 63.0 to 74.4), and 83.2% (95% CI 78.1 to 87.3), respectively. A total of 138 revisions were performed. The mean age at the time of revision was 48.2 years (23 to 72). Survival of all subsequent revision procedures, revised acetabular, and revised femoral components at 15 years’ follow-up with the endpoint of revision for any reason was 70.3% (95% CI 56.1 to 80.7), 69.7% (95% CI 54.3 to 80.7), and 76.2% (95% CI 57.8 to 87.4), respectively. A Girdlestone excision arthroplasty was required in six of 860 patients (0.7%). Conclusion. The long-term outcome of cemented primary and subsequent revision THA is promising in these young patients. We showed that our philosophy of using impaction bone grafting in patients with acetabular and femoral defects is a very suitable option when treating young patients. Surgeons should realize that knowledge of the outcome of subsequent revision surgery, which is inevitable in young patients, must be communicated to this group of patients prior to their initial THA.

Aims. One-stage revision hip arthroplasty for periprosthetic joint infection (PJI) has several advantages; however, resection of the proximal femur might be necessary to achieve higher success rates. We investigated the risk factors for resection and re-revisions, and assessed complications and subsequent re-revisions. Methods. In this single-centre, case-control study, 57 patients who underwent one-stage revision arthroplasty for PJI of the hip and required resection of the proximal femur between 2009 and 2018 were identified. The control group consisted of 57 patients undergoing one-stage revision without bony resection. Logistic regression analysis was performed to identify any correlation with resection and the risk factors for re-revisions. Rates of all-causes re-revision, reinfection, and instability were compared between groups. Results. Patients who required resection of the proximal femur were found to have a higher all-cause re-revision rate (29.8% vs 10.5%; p = 0.018), largely due to reinfection (15.8% vs 0%; p = 0.003), and dislocation (8.8% vs 10.5%; p = 0.762), and showed higher rate of in-hospital wound haematoma requiring aspiration or evacuation (p = 0.013), and wound revision (p = 0.008). The use of of dual mobility components/constrained liner in the resection group was higher than that of controls (94.7% vs 36.8%; p < 0.001). The presence and removal of additional metal hardware (odds ratio (OR) = 7.2), a sinus tract (OR 4), ten years’ time interval between primary implantation and index infection (OR 3.3), and previous hip revision (OR 1.4) increased the risk of proximal femoral resection. A sinus tract (OR 9.2) and postoperative dislocation (OR 281.4) were associated with increased risk of subsequent re-revisions. Conclusion. Proximal femoral resection during one-stage revision hip arthroplasty for PJI may be required to reduce the risk of of recurrent or further infection. Patients with additional metalware needing removal or transcortical sinus tracts and chronic osteomyelitis are particularly at higher risk of needing proximal femoral excision. However, radical resection is associated with higher surgical complications and increased re-revision rates. The use of constrained acetabular liners and dual mobility components maintained an acceptable dislocation rate. These results, including identified risk factors, may aid in preoperative planning, patient consultation and consent, and intraoperative decision-making.

We investigated whether our policy of routine re-excision of the tumour bed after an unplanned excision of a soft-tissue sarcoma was justified. Between April 1982 and December 2005, 2201 patients were referred to our hospital with the diagnosis of soft-tissue sarcoma, of whom 402 (18%) had undergone an unplanned excision elsewhere. A total of 363 (16.5%) were included in this study. Each patient was routinely restaged and the original histology was reviewed. Re-excision was undertaken in 316 (87%). We analysed the patient, tumour and treatment factors in relation to local control, metastasis and overall survival. Residual tumour was found in 188 patients (59%). There was thus no residual disease in 128 patients of whom 10% (13) went on to develop a local recurrence. In 149 patients (47%), the re-excision specimen contained residual tumour, but it had been widely excised. Local recurrence occurred in 30 of these patients (20%). In 39 patients (12%), residual tumour was present in a marginal resection specimen. Of these, 46% (18) developed a local recurrence. A final positive margin in a high-grade tumour had a 60% risk of local recurrence even with post-operative radiotherapy. Metastases developed in 24% (86). The overall survival was 77% at five years. Survival was related to the grade of the tumour and the finding of residual tumour at the time of re-excision. We concluded that our policy of routine re-excision after unplanned excision of soft-tissue sarcoma was justified in view of the high risk of finding residual tumour

The purpose of this study was to determine the surgical risks and recurrence rate associated with the excision of osteochondroma from the long bones most frequently operated on in our institution; the femur, tibia, humerus and fibula. Two hundred and twenty four osteochondromata were excised in total between July 1992 and January 2001. The medical records and radiographs of 126 patients who had 147 osteochondromata excised from the femur, tibia, humerus and fibula were reviewed. Of these, 30 patients presented with multiple osteochondromata, accounting for 48 of the 147. Fifty three involved the femur (2 proximal), 55 the tibia (16 distal), 12 the fibula (2 distal) and 27 the proximal humerus. The mean age at excision was 12.5 years (2–18 years) and the mean follow-up was five years (1 to 10 years). There were 15 surgical complications (10% of excisions) including one compartment syndrome, five superficial wound infections, two haematoma formations which required evacuation, one partial wound dehiscence, one deep infection with sinus formation which required excision, one sural nerve and one saphenous nerve neuropraxia, one cutaneous nerve entrapment and two hypertophic scar/keloid formations. The patient with the compartment syndrome had excision of a distal femoral, proximal tibial and fibular osteochondroma during the same procedure and was diagnosed to have won Willebrand disease after the surgery. There were eight recurrences involving five patients with multiple osteochondromata and three in whom the excision was incomplete due to the proximity to neurovascular structures. Surgical risks related to excision of osteochondroma are relatively frequent and must not be underestimated. Excision should therefore only be performed if strongly indicated. The recurrence rate (5.5%) seems to be higher than previously reported in the literature (2%) and generally affects patients with multiple osteochondromata. Incomplete excision resulted in recurrence in all our cases

We measured the tension in the interosseous membrane in six cadaveric forearms using an in vitro forearm testing system with the native radial head, after excision of the radial head and after metallic radial head replacement. The tension almost doubled after excision of the radial head during simulated rotation of the forearm (p = 0.007). There was no significant difference in tension in the interosseous membrane between the native and radial head replacement states (p = 0.09). Maximal tension occurred in neutral rotation with both the native and the replaced radial head, but in pronation if the radial head was excised. Under an increasing axial load and with the forearm in a fixed position, the rate of increase in tension in the interosseous membrane was greater when the radial head was excised than for the native radial head or replacement states (p = 0.02). As there was no difference in tension between the native and radial head replacement states, a radial head replacement should provide a normal healing environment for the interosseous membrane after injury or following its reconstruction. Load sharing between the radius and ulna becomes normal after radial head Replacement. As excision of the radial head significantly increased the tension in the interosseous membrane it may potentially lead to its attritional failure over time.

Patient reported outcomes and satisfaction scores following excision of interdigital Morton's neuroma have been recently established. However, little is known regarding what patient factors affect these outcomes. This is the first and largest prospective study to determine which patient factors influence surgical outcome following Morton's neuroma excision. Over a seven-year period, 99 consecutive patients (112 feet) undergoing surgical excision of Morton's neuroma were prospectively studied. 78 patients were female with a mean age at operation of 56 years. Patient recorded outcomes and satisfaction were measured using the Manchester-Oxford Foot Questionnaire (MOXFQ), Short Form-12 (SF12) and a supplementary patient satisfaction survey three months pre and six months post-operatively. Patient demographics were recorded in addition to co-morbidities, deprivation, associated neuroma excision and other forefoot surgery. Obesity, deprivation and revision surgery proved to statistically worsen MOXFQ outcomes post-operatively (p=0.005, p=0.002 and p=0.004 respectively). Deprivation significantly worsened the mental component of the SF12 (p=0.043) and depression the physical component (p=0.026). No difference in outcome was identified for age, sex, time from diagnosis to surgery, multiple neuroma excision and other forefoot surgeries. 23.5percnt; of deprived patients were dissatisfied with their surgery compared to 7percnt; of the remaining cohort. Patient reported outcomes following resection of symptomatic Morton's neuroma are shown to be less favourable in those patients who display characteristics of obesity, depression, deprivation and in those who undertake revision neuroma resection. Surgery can be safely delayed, as time to surgery from diagnosis bears no impact on clinical outcome

Introduction. The popliteus tendon is a component of the posterolateral corner of the knee, which controls the external rotation of the tibia. In our clinical practice, the femoral footprint of the popliteus tendon is occasionally excised as the bone is resected during total knee arthroplasty (TKA). Although the excision of the popliteus tendon femoral footprint could result in excessive external rotation of the tibia and may have adverse effects on the long-term outcomes of TKA, little attention has been paid to the popliteus tendon femoral footprint during TKA. The purpose of the present study is to assess the frequency of the excision and its associated risk factors. Methods. One hundred eleven knees of 90 patients with varus knee osteoarthritis who underwent primary TKA were included in the present study. There were 13 males and 77 females, and their average age was 74 years. The NexGen knee replacement system (Zimmer, Warsaw, IN, USA) was used in all cases. The excision of the popliteus tendon femoral footprint was intraoperatively evaluated, and the patients were divided into three groups depending on the status of the femoral footprint, i.e., the preserved, partially excised, and completely excised groups. The thickness of the distal femoral osteotomy, femoral component size, and background data including height, body weight, gender, and age were compared among these groups. Analysis of variance followed by Student–Newman–Keuls test were used to compare the continuous values and ordinal scales. Gender was compared using Fisher's exact test and residual analysis. Statistical significance was set at p < 0.05. Results. The popliteus tendon femoral footprint was preserved in 48 knees (43.2%), partially excised in 45 knees (40.5%), and completely excised in 18 knees (16.2%). The mean patient height was 154.6, 150.1, and 148.7 cm in the preserved, partially excised, and completely excised groups, respectively, and these differences were statistically significant (p < 0.01). Femoral component size was significantly smaller in the partially and completely excised groups compared with that in the preserved group (p < 0.05). The preserved group included more male patients (p < 0.01). There were no significant differences in body weight, age, and thickness of the distal femoral osteotomy among the groups. Conclusion. The partial or complete excision of the popliteus tendon femoral footprint was observed in more than half of the evaluated knees. Shorter height, smaller femoral component size, and female sex were considered to be the possible risk factors for the excision of the popliteus tendon femoral footprint

Chondrosarcoma of bone is a surgical disease and excision with wide margins is the optimum treatment. Sometimes the size or location of the tumour at the time of diagnosis mean that only a marginal excision can be achieved. The effect of the margin of excision on outcome is investigated. Method. All patients with newly diagnosed primary chondrosarcoma of bone and without metastases at the time of diagnosis were identified from a prospective database. Their outcome was investigated to assess whether the margin of excision affected outcome. Results. 492 patients were included in the analysis with a mean age of 48. The mean tumour size was 11cm and 59% were male. The 10 year tumour specific survival was 85% for clear cell (N=7) and grade 1 (N=210), 60% for grade 2 (N=180), 47% for grade 3 (N=59) and 16% for dedifferentiated (N=36). The 10 year local recurrence free survival was 86% (clear cell), 73% (grade 1), 67% (grade 2), 36% (grade 3) and 56% dedifferentiated. Local recurrence was strongly related to older age (p=0.0065), grade (p⋋0.0001) and margins (p⋋0.0001). Patients who developed local recurrence had a 43% survival at 10 years compared with 76% for those who did not (p⋋0.0001). They also had a 49% risk of developing metastases compared to a 17% risk for those without local recurrence (p⋋0.0001). However most of these patients had metastases before developing LR(57%). 16 of 65 patients with local recurrence but no metastases, died due to local progression (usually pelvic or spinal tumours). There was however no relation of the margin of excision to either the risk of developing metastases or survival for any grade of tumour. Conclusion. Whilst local control is strongly related to margins of excision and grade, overall survival is related principally to grade but not to margins

Wrist ganglia are the commonest benign tumours of the hand consisting of a collagenous walled cavity containing gelatinous mucin material. These lesions can be managed by either reassurance alone, aspiration or surgical excision. However studies evaluating patient outcomes following these treatment modalities are limited and between them have often presented inconsistent results. Some recently published data has suggested that there is no long-term benefit of excision or aspiration over reassurance alone and as a result surgical excision of wrist ganglia has fallen out of favour with some health care trusts. This aim of this retrospective, questionnaire based study was to assess patient outcomes following wrist ganglion excision surgery and to compare these results with current published evidence. Sixty two patients were identified from the hospital records database between July 2003 and March 2008. Fifty patients (80.6%) responded to a questionnaire by post or telephone call with a mean time to follow up of thirty nine months (range 16 to 71 months). Pain and cosmetic concern were the primary symptoms preoperatively, experienced by 78% and 70% of patients respectively. 26% to 48% of patients experienced other symptoms such as pins and needles, numbness, weakness and stiffness. Following surgery, there was a statistically significant reduction in all symptoms experienced. Ganglions recurred at the same location in five patients (12%) of which four would consider further surgery. 96% of patients were satisfied with the treatment they received. Our results regarding symptomatic relief are comparable with current published data. In addition our data provides further evidence that ganglion excision surgery prevents recurrence to a greater extent than either aspiration or reassurance alone. Furthermore our recurrence rate is lower than other published reports evaluating ganglion excision surgery which we believe underestimate the benefits offered by this treatment modality. As a result, wrist ganglion excision surgery remains an important treatment modality offering excellent results in terms of symptom resolution, patient satisfaction and ganglion recurrence

Twenty-two patients who underwent thirty-four Kellers’ excision arthroplasty were followed up at an average of thirty-five months. They were assessed using AFAOS, satisfaction and radiological evaluation. The average hallux score was eighty- five (fifty-two to one hundred) while the average lesser toe score was ninety- two (seventy-five to one hundred). The average pain score was thirty- six (twenty to forty) for the hallux and thirty-eight for the lesser toes (twenty to forty). 23/34(68%) had good to excellent, 6/34 (18%) had fair and 5/34(14%) had poor results. The great toe was moderately short, but most patients do not seem to mind this. 91% patients were satisfied with the results. We undertook a retrospective study of Kellers’ excision arthroplasty done over the last seven years to assess the medium term results. Twenty-two patients who underwent thirty- four Kellers’ excision arthroplasty were followed up at an average of thirty-five months. They were followed up using the AFAOS, patient satisfaction and radiological evaluation. The average age at the time of surgery was 67.4 years. There were seventeen females (twenty-five feet) and five males (nine feet). All patients underwent bunionectomy along with excision of proximal third of the proximal phalanx. Of these twenty underwent K wire stablization of the hallux following excision. The average hallux score was eighty- five (range sixty-two to one hundred) while the average lesser toe score was ninety- two (range seventy-five to one hundred). The average pain score was thirty- six (range twenty to forty) for the hallux and thirty-eight for the lesser toes (twenty to forty). 23/34 (68%) had good to excellent, 6/34 (18%) had fair and 5/34(14%) had poor results. The average correction of the hallux valgus was 9o. The average IMT was 25o preoperatively and 18o postoperatively. The average shortening was 7 mm. Complications included two cases of transfer metatarsalgia and two cases of clawing of the lesser toes. One patient developed abscess which settled after incision and drainage. Thirty-one out of thirty-four patients were satis-fied with the final outcome and thirty out of thirty-four patients would have the operation on the other feet. The great toe is moderately short, but most patients do not seem to mind this. 91% patients were satisfied with the results
