Introduction: Clear cell sarcoma is a very rare tumor of the tissues described also as melanoma of the tissues. It is a low-grade tumor mostly located in the hand. Aim: To present 3 patients with this rare tumor located in the hand and to describe the therapy, which is wide or radical excision after control of the local lymphnodes. Methods-materials: We present three patients treated in our department the last 3 years. The tumor was located at the ring finger, the little finger and in the thenar. All the patients primary were treated at an other center with insufficient removal of the tumor. At the time they presented in our department they all had local recurrence. At our hospital after control of the local lymphnodes (with MRI or scanning), which was negative, two patients were treated with ray amputation and the patient with tumor location in the thenar was treated with wide local excision and skin grafting. By the histological examination the surgical margins in all patients were clear and so Ro therapy or chemotherapy were not further needed. All patients returned to their primary work. Until now we have no further recurrence. Conclusions: Clear cell sarcoma of the hand is a rare tumor of the tissues with low-grade malignancy and good prognosis if treated by wide excision. Ray amputation gives an excellent therapeutic and functional outcome

Introduction. Hand tumors are usually rare and there is not much literature about series of cases. We have studied a series of 110 cases. Hand tumors do consists of both benign and malignant cases. Methods. We studied series of 110 cases at Karnataka Institute of Medical Sciences, Hubli and Mysore Medical College & Research Institute, Mysore. We retrospectively reviewed the records of 110 patients who underwent double ray amputations at our center over few years: few had amputations of the fourth and fifth rays and others amputation of the second and third rays. Mean age at surgery was 34 years (range, 10–45 years), and minimum follow up was 64 months (mean, 98 months; range, 64–136 months). Some patients had high-grade soft tissue sarcomas of the hand, synovial sarcomas, malignant peripheral nerve sheath tumors, and undifferentiated sarcoma. No patients had detectable metastases at surgery. Results. All patients were completely disease-free at latest follow up. One patient was alive with lung metastases detected 32 months after surgery. No patients developed local tumor recurrence. Functional assessment showed a mean Musculoskeletal Tumor Society score of 24 (range, 19–28) and mean grip strength 24% of the contra lateral side (range, 17%–35%). Conclusions. The majority of osseous tumors of the hand are benign. The surgeon who evaluates and treats osseous tumors of the hand has to be familiar with limb anatomy, tumor biology, various presentations of the tumors and the range of treatment possibilities and their limitations. Lesions in the hand more often present earlier in their course than those at other sites, just because they are more likely to superficial and easily noticed. Ganglion cyst is the most frequently encountered comprising 50–70% of benign tumors of hand. Enchondroma was the next common benign bone tumour followed by osteoid osteoma, osteoblastoma, aneurismal bone cyst, giant cell tumor, epidermoid cyst, and osteochondroma. Although malignant neoplasms in the hand that arise from tissues other than the skin are very rare, the hand may be the site of distant breast, lung, kidney, esophagus, or colon adenocarcinoma metastases, most of which have a predilection for the distal phalanges. Malignant tumours of the hand are rare, although there remain many instances in which marginal excisions are performed for unsuspected malignant hand lesions. Suboptimal biopsy incisions and inadvertent contamination during these excisions may result in larger resections or amputations being necessary to ensure complete removal of the tumour with negative margins

Foot osteomyelitis is a common problem for which management is variable and few guidelines exist. To present our treatment protocol and the results in 36 patients (20 men, 16 women, mean age: 49.5 years) with osteomyelitis distal to the ankle, followed up for 17.6 months (range: 3–64). Bone infection involved toes (n=4), lesser metatarsals (n=11), hallux (n=3), midfoot (n=4), calcaneus (n=9), whereas 4 cases presented as generalised osteomyelitis. Postoperative infection was the cause in 10 cases. Eleven patients were classified as host-type A, 14 as B and 11 as C. A draining sinus was present in 28 cases. The treatment protocol included surgical debridement, the bead-pouch technique for local antibiotic administration and closure primarily (n=27), or by secondary healing (n=5), skin graft (n=2), local fasciocutaneous (n=1), or free vascularised muscle flap (n=1). Systemic antibiotics according to cultures were administered for 5–7 days. Generalized Charcot osteomyelitis was an indication for amputation. Mean hospital stay was 13.8 days (range 1–34) and 2.7 (range 1–7) surgical procedures per patient were recorded. Infection control was achieved in 26 cases (72.2%), whereas amputations were performed in 10 cases (27.8%). Below-knee amputation was undertaken in 4 host-type C patients with Charcot osteomyelitis of the foot. Ray amputations were performed in 4 diabetic feet. Six amputees were classified as host-C and 3 as host-B. One host-type A patient with recurrent post-traumatic toe osteomyelitis, underwent a distal phalanx amputation as definitive solution. Amputation rates were 55% among host-C, 22% among host-B and 9% among host-A patients (p< 0.001). Diffuse foot osteomyelitis in systemically compromised patients resulted in high amputation rates. Better results were obtained in non-compromised hosts and focal osteomyelitis

Aims

Tenosynovial giant cell tumour (TGCT) is a rare benign tumour of the musculoskeletal system. Surgical management is fraught with challenges due to high recurrence rates. The aim of this study was to describe surgical treatment and evaluate surgical outcomes of TGCT at an Australian tertiary referral centre for musculoskeletal tumours and to identify factors affecting recurrence rates.

Twenty cases of malignant sarcomas of the foot and ankle included: four osteosarcomas, three Ewing’s sarcomas, three chondrosarcomas, three fibrosarcomas, five synovial cell sarcomas, one clear cell sarcoma and one malignant schwannoma. Five-year survival was: three of the nine who had B-K amputation, five of the nine who had more distal amputation or local resection, for a total of eight of eighteen. More distal amputation than B-K or local resection was offered if plantar sensation and stability of the foot could be retained, and was accepted by half of the patients. There were no local recurrences of eighteen operated. Twenty cases of malignant sarcomas of the foot and ankle seen over a ten-year period from 1985 to 1995 were reviewed retrospectively. Eleven tumors arose from bone and nine from soft tissue. The bone tumors were: four osteosarcomas, three Ewing’s sarcomas, three chondrosarcomas, and one fibrosarcoma. The soft tissue sarcomas were: five synovial cell sarcomas, two fibrosarcomas, one clear cell sarcoma and one malignant schwannoma. The average age for all patients was twenty-four years. Two patients presented with chest metastases, both had palliative radiation and one had palliative B-K amputation. The surgical treatment given for the eighteen non-metastatic cases was: B-K amputation nine, Symes, Chopart, or ray amputation six, and wide excision of the tumor three patients. Five-year survival was eight of eighteen: three of the nine who had B-K amputation, four of the six who had more distal amputation, and one of the three who had local resection. There were no local recurrences, all deaths were from distant metastases. Although B-K amputation is often recommended, in our series more distal amputation or local resection was offered for the non-metastatic patient if plantar sensation and stability of the foot could be retained. This gave good function in nine of eighteen patients, with no local recurrences. A long duration of symptoms before presentation or referral influenced the outcome of the disease. In selected patients, amputation more distal than B-K level or wide local resection can give good function without compromising the prognosis

We present the long-term results of a single institute’s experience of the Mann 3 in 1 procedure. This prospective study initially selected 36 feet (25 patients) with severe hallux valgus, classified by a HV angle < 40° or IM angle> 15°, for the Mann 3 in 1 procedure. Preoperative and postoperative standing radiographs were taken to calculate the correction of the deformity, and a postoperative subjective questionnaire was completed which was based on the assessment criteria suggested by the American Orthopaedic Foot and Ankle Society in 1984. The initial follow-up was completed at up to one year. The original cohort of patients was contacted again at 10 years (range 9–11 years) to repeat the same questionnaire and radiographs. In total 19 patients (27 feet) were contactable with an average age of 51 years (range 34–74). The questionnaire revealed one patient unable to perform the same occupation and three patients unable to perform the same activities due to ongoig problems with the operated feet. Thirteen patients had to wear modified footwear but only 2 required specially made shoes. Sixteen of the nineteen (84%) were pleased or satisfied with pain relief and appearance following the procedure, with 14 stating that they would undergo the procedure again given the same circumstance and 5 patients that would not. The complications included 8 patients requiring screw removal, 2 patients with metatarsalgia, one patient undergoing multiple further corrective procedures and one requiring a second ray amputation for osteomyelitis. Sixteen patients (23 feet) were available for repeat radiographic assessment. This revealed that there had been some recurrence of the deformity with the initial correction of the HV angle being a mean of 40° (range 36–51°) to 15° (9–23°) at up to one year and 23° (0–52°) at ten years. Similarly with the mean IM angle initially corrected from 18° (15–25°) to 8.5°(6–12°), being 14° (7–20°) at ten years. In conclusion, despite some recurrence of the deformity on x-ray the subjective satisfaction with this procedure is good. Care should be taken in patient selection but the Mann 3 in 1 appears to be a good procedure for the correction of severe Hallux Valgus

Introduction: A ‘whoops’ procedure is when a lump, which subsequently turns out to be a soft tissue sarcoma (STS), is shelled out by a surgeon who is not aware of the diagnosis. In many cases residual tumour will be left behind necessitating further surgery. The significance of a whoops procedure in terms of survival and local control remains uncertain. This study has used case matched controls to compare outcome between two groups. Method: 794 patients of soft tissue sarcoma with minimum follow up of 5 years were found on our prospectively collected database. 113 were whoops cases, 96 had restaging and reexcision. An observer blinded to the outcome of patients matched the whoops cases with virgins by known prognostic factors i.e. grade, depth, patient age, site, size and diagnosis of the tumour. We have investigated outcome in terms of local control, metastatic disease and survival by known prognostic factors and by their status at presentation. Results: 96 patients with a whoops procedure were compared with 96 referred directly to our unit. Despite attempts to match patients with as many variables as possible there was a tendency for the patients with whoops to have smaller tumours that were subcutaneous, they were however well matched for grade and stage at diagnosis. 64% of whoops patients had adequate final margin whereas only 44% of virgins had adequate margins. Overall 1.43 additional operations were needed to achieve final margins for whoops cases as against 0.21% for virgin cases. Overall 27% patients had amputation 20% for whoops and 34% for virgin cases nearly 60% were ray amputations of foot or hand. Overall 50% had radiotherapy and 25% had chemotherapy. There was no statistical difference in local recurrence or survival of patients between whoops and virgins at 5 years follow up. Inadequate margins and residual tumour were significant risk factors for local recurrence and high grade, size more than 5 cm, and age more than 50 years were significant prognostic factors for overall survival of the patients. Conclusion: Inadvertent surgical excision of a STS is not desirable but does not seem to lead to an adverse outcome in this series in which wide re-excision of the area involved has been carried out

Introduction: Management strategies and results in 30 cases of foot osteomyelitis are presented. Patients-Methods: From 1/2003 – 1/2006, 30 patients (15 men, 15 women, mean age 47.7 years, range 1.5–82) presenting with foot osteomyelitis were treated. Mean hospital stay was 12.6 days (range 1–45) and 1.3 hospital admissions were recorded (range 1–4). The follow-up period averaged 15.7 months (range 3–56). Bone infection involved the toes in 3 cases, the metatarsals in 9, the head of the hallux in 2, the midfoot in 3, the calcaneus in 9, whereas 3 cases presented as generalized charcot’s osteomyelitis. Eleven patients were classified as host-type A, 10 as B and 9 as C. Nine patients were diabetic, one rheumatoid, four had vascular insufficiency, two had insensate feet. An open calacaneal fracture was the cause in two cases, whereas ORIF of a closed calacaneal fracture in one, ORIF of metatarsal fractures in one and hallux valgus corrective surgery in two. One paediatric patient with calcaneal osteomyelitis developed subtalar arthritis. A draining sinus/wound was present in 24 cases. Each patient underwent an average of 2.3 surgical procedures (range 1–7). The treatment protocol included surgical debridement, use of the bead-pouch technique for local antibiotic administration and closure primarily (n=23), or by secondary healing (n=3), skin graft (n=2), local fasciocutaneous (n=1), or free vascularized muscle flap (n=1). Systemic antibiotics according to cultures were administered for 5–7 days. Amputation was undertaken if salvaging or reconstructive procedures could not be undertaken. Results: Infection control (salvageable cases) was achieved in 23 cases (76.7%), whereas amputations were performed in 7 cases (23.3%). Four amputees were classified as host C (57.1%), whereas a significantly lower rate of patients successfully treated (21.7%) were host-C (p=0.0008). A below knee amputation was undertaken in two host-type C patients with generalized osteomyelitis of the foot. One 1st ray and two 1st and 2nd ray amputations were performed for not salvageable diabetic feet infections. Finally in 3 cases of posttraumatic chronic toe osteomyelitis in host-type A patients, a distal phalanx amputation was the definite solution. One patient developed a septic TKR in the contralateral leg and one diabetic patient developed osteomyelitis at a different location in the earlier affected foot. Conclusions: The treatment strategy of radical debridement, local antibiotic delivery by the bead-pouch technique and use of flaps if needed, successfully treated salvageable feet. Amputation was the solution in neglected cases and in immunocompromised patients

Aims

COVID-19 necessitated abrupt changes in trauma service delivery. We compare the demographics and outcomes of patients treated during lockdown to a matched period from 2019. Findings have important implications for service development.
