Soft-tissue reconstruction after soft-tissue sarcoma resection: the clinical outcomes of 24 patients.

PURPOSE: Pedicle or free-flap reconstruction is important in surgical sarcoma management. Free flaps are indicated only when pedicle flaps are considered inadequate; however, they are associated with a higher risk of flap failure, longer surgical times, and technical difficulty. To determine the skin defect size that can be covered by a pedicle flap, we investigated the clinical outcomes and complications of reconstruction using pedicle flaps vs. free flaps after sarcoma resection. METHODS: We retrospectively studied the medical records of 24 patients with soft-tissue sarcomas who underwent reconstruction using a pedicle (n = 20) or free flap (n = 4) following wide tumour resection. RESULTS: All skin defects of the knee, lower leg, and ankle were reconstructed using a pedicle flap. Skin defects of the knee, lower leg, and ankle were covered by up to 525 cm2, 325 cm2, and 234 cm2, respectively. The amount of blood loss was significantly greater in the free-flap group than in the pedicle flap group (p = 0.011). Surgical time was significantly shorter in the pedicle flap group than in the free-flap group (p = 0.006). Total necrosis was observed in one (25%) patient in the free-flap group; no case of total necrosis was observed in the pedicle flap group. CONCLUSION: Less blood loss, shorter surgical time, and lower risk of total flap necrosis are notable advantages of pedicle flaps over free flaps. Most skin defects, even large ones, of the lower extremities following sarcoma resection can be covered using a single pedicle flap or multiple pedicle flaps.

Intraneural ganglion cysts of the peroneal nerve.

BACKGROUND: Intraneural ganglion cysts of the peroneal nerve are rare, and there is lack of evidence for the surgical management of this entity. We performed this study to evaluate the imaging, diagnosis, treatment and outcome of seven patients with intraneural ganglion cysts of the peroneal nerve. MATERIALS AND METHODS: We retrospectively studied the files of seven patients with intraneural ganglion cysts of the peroneal nerve, diagnosed and treated from 2016 to 2019. Diagnostic approach included clinical examination of the leg and foot, magnetic resonance imaging, nerve conduction studies, surgical excision of the cyst and histological examination. The mean follow-up was 2 years (range 1-3.5 years). We evaluated the time and methods for surgical treatment, and the clinical outcomes of the patients. RESULTS: All patients presented symptoms of peripheral compression neuropathy; three patients presented with foot drop. The intraneural ganglion cysts were excised in all cases in addition to knee articular nerve branch transection to avoid cysts recurrence. Postoperatively, all patients experienced complete neurological recovery without clinical evidence of intraneural ganglion cysts recurrences. CONCLUSION: The treating physicians should be aware of intraneural ganglion cysts of the peroneal nerve in patients presenting with limb weakness, sensory deficits at the lateral and anterior side of the leg and foot, paresis or paralysis of the foot and ankle. MR imaging is the imaging modality of choice for a clear and accurate preoperative diagnosis to avoid misdiagnosis and wrong treatment. In case of doubt, these patients should be managed in an orthopedic oncology setting with microsurgery facilities available for complete excision of the intraneural ganglion cyst.

Chondrosarcomas of the small bones: analysis of 44 patients.

BACKGROUND: Chondrosarcomas of the small bones of the hands and feet are uncommon and account for less than 2% of all chondrosarcomas in the skeleton; a 4.2% rate of malignant degeneration of enchondromas to secondary chondrosarcomas has been reported. We performed this study to assess the outcome of the patients with chondrosarcomas of the small bones. We hypothesized that the presumed better prognosis of chondrosarcomas in these locations could be biased as the majority of these tumors tend to be of lower grades and are removed when still small sized, and that less aggressive surgery has an adverse effect on local control MATERIALS AND METHODS: We retrospectively studied the files of 44 patients with chondrosarcomas of the small bones of the hands and feet. There were 23 female and 21 male patients with a mean age of 50.9 years (range, 6-86 years). The mean follow-up was 13 years (range, 5-40 years). We recorded the patients' details including gender and age at diagnosis, type and duration of symptoms, tumor location and histology, type of surgery and complications, and outcome (local recurrences and metastases). RESULTS: The most common anatomical location for chondrosarcomas of the hands was the metacarpals and proximal phalanges. The most common presenting symptom was a slowly enlarging palpable mass. Overall, 36 chondrosarcomas were secondary to a pre-existing cartilaginous tumor. Patients with syndromes were affected in younger age compared to the others. The mean age at diagnosis was higher for higher grade chondrosarcomas. Overall, 13 patients (29.5%) experienced a local recurrence; the rate of local recurrence was higher after curettage regardless the histological grade of the tumors. After wide resection of the first local recurrence, five patients experienced local re-recurrence. Five patients (11.4%) experienced lung metastases, two patients at presentation. All these patients had a high grade chondrosarcomas. At the last follow-up, one patient with lung metastases died from disease, and another patient died from unrelated cause. CONCLUSIONS: The patients with chondrosarcomas of the small bones of the hands and feet may have a dismal outcome if treated improperly. A careful treatment planning is required to avoid unnecessary amputations. Curettage is associated with a high rate for local recurrence that should be treated with a more aggressive surgical resection to avoid re-recurrences. Although the risk is low, the patients may develop lung metastases, especially those with higher grade chondrosarcomas, therefore, they should be staged and followed closely.

Double fractures of the femur: a review of 16 patients.

BACKGROUND: Double ipsilateral femoral fractures account for 1-9% of femoral fractures. There is no clear advantage between single or double implant osteosynthesis. We present a series of patients with double ipsilateral femoral fractures, to address the challenges in treatment, namely the implants for osteosynthesis and complications of treatment. MATERIALS AND METHODS: We retrospectively studied 16 patients (7 men, 9 women; mean age, 51 years) treated from January 2015 to December 2018. Motor vehicle accidents were the leading cause of injury. Types of fractures were pertrochanteric and shaft (6), pertrochanteric and distal (2), double shaft (3), neck and shaft (2), neck and distal (1), shaft and distal (1), and triple fracture including a pertrochanteric, shaft and distal (1). In five patients, two different implants were used (plate and screws, cannulated hip screws, femoral nail), whereas in 11 patients a long femoral nail was used. RESULTS: Fourteen patients experienced union at a mean of 3 months (2-6 months). Two patients experienced nonunion: both had plate and screws osteosynthesis. One patient died 15 days after admission from polytrauma and another patient experienced central venous catheter thrombosis and pneumonia. Surgical complications (2 patients) included a thigh skin necrosis, and external fixator pin tract infection/infected non-union. Weight-bearing was delayed in all patients; full weight-bearing was allowed in 11 patients at 4 months postoperatively, and in four patients at 5 months. CONCLUSION: Due to the rarity and the difficulty of standardization of double ipsilateral femoral fractures, there is variable information on the optimal osteosynthesis of the fractures and the outcome of the patients. It seems that closed reduction and long hip nailing is the treatment of choice, with few complications.

Epithelioid Hemangioma of Bone: A Rare Vascular Neoplasm. A Case Report and Literature Review.

Epithelioid hemangioma (EH) of bone is a rare benign, albeit locally aggressive vascular neoplasm. It is usually solitary and involves the metaphysis or diaphysis of long tubular bones, especially in the lower extremities. Rarely it may present as multifocal lesions. The differential diagnosis includes malignant vascular bone tumors such as epithelioid hemangioendothelioma and epithelioid angiosarcoma. Clinical presentation and radiographic and histological findings are not specific and diagnosis is based mostly on immunohistochemical and molecular studies. There is no consensus regarding the optimal treatment. Curettage and bone grafting or en bloc resection are the current treatment options, however local recurrence have been reported. We present a case of multifocal EH of the distal tibia, distal fibula and hindfoot in a 38 year-old male managed with curettage, radiofrequency ablation and cement osteoplasty. The imaging features, histological findings and treatment options of this rare vascular tumor are discussed.

The Hippocratic Oath: Analysis and Contemporary Meaning.

The Hippocratic oath is traditionally taken by medical school graduates at the time of their graduation, either in its original form or in a modern variation. It is considered the earliest expression of medical ethics, establishing principles of ethics that remain of paramount significance today. However, it was written in antiquity, whereas medicine has been constantly evolving. This article reviews, analyzes, and interprets each section of the oath to determine to what extent it remains relevant to contemporary medicine. [Orthopedics. 2021;44(5):264-272.].
