Aims

The aim of this study was to assess the clinical and radiological outcomes of an antiprotrusio acetabular cage (APC) when used in the surgical treatment of periacetabular bone metastases.

Aims

Time to treatment initiation (TTI) is generally defined as the time from the histological diagnosis of malignancy to the initiation of first definitive treatment. There is no consensus on the impact of TTI on the overall survival in patients with a soft-tissue sarcoma. The purpose of this study was to determine if an increased TTI is associated with overall survival in patients with a soft-tissue sarcoma, and to identify the factors associated with a prolonged TTI.

Aims. With recent progress in cancer treatment, the number of advanced-age patients with spinal metastases has been increasing. It is important to clarify the influence of advanced age on outcomes following surgery for spinal metastases, especially with a focus on subjective health state values. Methods. We prospectively analyzed 101 patients with spinal metastases who underwent palliative surgery from 2013 to 2016. These patients were divided into two groups based on age (< 70 years and ≥ 70 years). The Eastern Cooperative Oncology Group (ECOG) performance status (PS), Barthel index (BI), and EuroQol-5 dimension (EQ-5D) score were assessed at study enrolment and at one, three, and six months after surgery. The survival times and complications were also collected. Results. In total, 65 patients were aged < 70 years (mean 59.6 years; 32 to 69) and 36 patients were aged ≥ 70 years (mean 75.9 years; 70 to 90). In both groups, the PS improved from PS3 to PS1 by spine surgery, the mean BI improved from < 60 to > 80 points, and the mean EQ-5D score improved from 0.0 to > 0.7 points. However, no significant differences were found in the improvement rates and values of the PS, BI, and EQ-5D score at any time points between the two groups. The PS, BI, and EQ-5D score improved throughout the follow-up period in approximately 90% of patients in each group. However, the improved PS, BI, and EQ-5D scores subsequently deteriorated in some patients, and the redeterioration rate of the EQ-5D was significantly higher in patients aged ≥ 70 than < 70 years (p = 0.027). Conclusion. Palliative surgery for spinal metastases improved the PS, activities of daily living, and quality of life, regardless of age. However, clinicians should be aware of the higher risk of redeterioration of the quality of life in advanced-age patients. Cite this article: Bone Joint J 2020;102-B(12):1709–1716

Aims

Survival rates and local control after resection of a sarcoma of the pelvis compare poorly to those of the limbs and have a high incidence of complications. The outcome for patients who need a hindquarter amputation (HQA) to treat a pelvic sarcoma is poor. Our aim was to evaluate the patient, tumour, and reconstructive factors that affect the survival of the patients who undergo HQA for primary or recurrent pelvic sarcoma.

Objectives

In this prospective cohort study, we investigated whether patient-specific finite element (FE) models can identify patients at risk of a pathological femoral fracture resulting from metastatic bone disease, and compared these FE predictions with clinical assessments by experienced clinicians.

Aims

Surgical intervention in patients with bone metastases from breast cancer is dependent on the estimated survival of the patient. The purpose of this paper was to identify factors that would predict survival so that specific decisions could be made in terms of surgical (or non-surgical) management.

We investigated the functional outcome in patients who underwent reverse shoulder replacement (RSR) after removal of a tumour of the proximal humerus. A total of 16 patients (ten women and six men) underwent this procedure between 1998 and 2011 in our hospital. Five patients died and one was lost to follow-up. Ten patients were available for review at a mean follow-up of 46 months (12 to 136). Eight patients had a primary and two patients a secondary bone tumour.

At final follow up the mean range of active movement was: abduction 78° (30° to 150°); flexion 98° (45° to 180°); external rotation 32° (10° to 60°); internal rotation 51° (10° to 80°). The mean Musculoskeletal Tumor Society score was 77% (60% to 90%) and the mean Toronto Extremity Salvage Score was 70% (30% to 91%). Two patients had a superficial infection and one had a deep infection and underwent a two-stage revision procedure. In two patients there was loosening of the RSR; one dislocated twice. All patients had some degree of atrophy or pseudo-atrophy of the deltoid muscle.

Use of a RSR in patients with a tumour of the proximal humerus gives acceptable results.

Aims. Bone is a common site of metastatic disease. Skeletal complications include disabling pain and pathological fractures. Palliative surgery for incurable metastatic bone lesions aims to preserve quality of life and function by providing pain relief and stable mobility with fixation or replacement. Current literature has few treatment studies. We present a 5 year longitudinal cohort study of surgery for metastatic bone disease at our large teaching hospital reviewing our complication and mortality rates. Methods. Patients that underwent palliative surgery for metastatic bone lesions were identified from operative records. Demographics, clinical details and outcomes were recorded. Kaplan-Meier analysis was used to calculate survivorship. Results. 43 patients were treated for 44 bone metastases (34 IM Nails, 9 prosthetic replacements, 1 plate). The median age at primary diagnosis was 66 (33–92). Lung cancer was the most common primary. 56% presented with complete fractures and 44% with impending fractures (median Mirel score of 10). Pertrochanteric bone lesions were the most common (74%). Two out of 43 patients died within one day of surgery. 30 day mortality was 12% and 45% at 1 year. In those surviving the 30 day perioperative period, we report a complication rate of 14%. One patient had a dislocated prosthesis. Two patients had delayed or non union and two patients had failure of metalwork. No patient required re operation. Conclusion. Our series observed a 5% fixation failure rate and significant perioperative mortality. Whilst surgery may offer benefit in the non moribund patient with pathological fracture the decision to offer prophylactic surgery is more difficult in light of the high perioperative mortality seen in our study. Indeed, the patients in our study who died within 24 hours of surgery had prophylactic fixations. We conclude that surgical intervention must be carefully considered with realistic expectations of outcomes

The aim of this study was to define the treatment criteria for patients with recurrent chondrosarcoma. We reviewed the data of 77 patients to examine the influence of factors such as the intention of treatment (curative/palliative), extent of surgery, resection margins, status of disease at the time of local recurrence and the grade of the tumour. A total of 70 patients underwent surgery for recurrent chondrosarcoma. In seven patients surgery was not a viable option. Metastatic disease occurred in 41 patients, appearing synchronously with the local recurrence in 56% of cases. For patients without metastasis at the time of local recurrence, the overall survival at a mean follow-up after recurrence of 67 months (0 to 289) was 74% (5 of 27) compared with 19% (13 of 50) for patients with metastasis at or before the development of the recurrence. Neither the type/extent of surgery, site of tumour, nor the resection margins for the recurrent tumour significantly influenced the overall survival.

With limited survival for patients with metastatic disease at the time of local recurrence (0% for patients with grade III and de-differentiated chondrosarcoma), palliative treatment, including local radiation therapy and debulking procedures, should be discussed with the patients to avoid long hospitalisation and functional deficits. For patients without metastasis at the time of local recurrence, the overall survival of 74% justifies an aggressive approach including wide resection margins and extensive reconstruction.

Introduction and purpose: The most frequent neurological complication of humeral fractures is radial nerve palsy. Most patients with humeral fractures and radial nerve palsy recover with conservative treatment. But a small percentage of patients require surgical treatment; these are patients who show no clinical improvement of their nerve lesion after 3 months of conservative treatment, those with an open fracture, an associated vascular lesion, secondary radial palsy or patients who require open fracture osteosynthesis. The aim of this study is to assess and analyze humeral fractures with radial palsy that have required surgical treatment. Materials and methods: A prospective pre and postoperative study with a protocol was carried out between 1999 and 2007 in which 28 patients with humeral fractures and radial palsy required surgical treatment. Of the patients studied 10 were women and 18 were men. Their ages varied from 18 to 74 years of age. As to the type of radial palsy, it was primary in 11 patients, secondary in 2 patients (included in the fracture callus) and postoperative in 15. Neurolysis was performed in 20 patients and fascicular grafts were used in 8. Results: Time to fracture healing was 14.2 + 5.6 weeks. The period of radial nerve recovery was 7.2 + 5.7 months. Neurolysis was performed in 20 patients and fascicular grafts in 8. There were 20 complete recoveries, 4 incomplete but useful, in 4 cases there was no recovery and palliative surgery was subsequently performed. Conclusions: Surgical treatment of humeral fractures with radial palsy is indicated in patients who show no clinical improvement of their nerve lesion after 3 months of conservative treatment, those with an open fracture, an associated vascular lesion, secondary radial paralysis or in patients who require an open fracture osteosynthesis. Functional recovery rates are high if surgery is carried out during the appropriate period of time. Treatment is neurolysis or fascicular grafts. Palliative surgery is reserved for cases in which complete recovery is not achieved

Introduction An international six-centre prospective observational cohort study. Objective. To assess the feasibility of radical surgical excisional treatment of spinal metastasis. Materials and methods. Patients with histologically confirmed spinal metastasis originating from epithelial primary site mostly treated with instrumented surgery were studied. Surgical strategies were either radical excisional (enbloc and debulking) or palliative decompressive surgery. Outcomes assessed were measures of quality of life including pain, mobility, sphincter and neurological functions. Results. A total of 223 patients with a mean age of 61 years and equal number of males and females were studied. Breast, renal, lung and prostate accounted for three quarters of tumours and 60% had metastasis that extended beyond one vertebra. Most patients presented with pain (92%), paraparesis (24%) and abnormal urinary sphincter 22% (5% were incontinent). Seventy four percent of patients underwent radical surgery, 92% of all patients had instrumented fixation. 73% of the radical group had improved pain control (63% for palliative group), 72% regained ability to walk (45% for palliative group), 92% maintained a functional neurological function of Frankel E/D (64% for palliative) and 55% had improved sphincter control (21% for palliative group). Overall of all petients who underwent surgery, 71% had improved pain control, 53% regained mobility, 64% improved by at least one Frankel grade or maintained normal neurology and 39% regained normal urinary sphincter function. While 18% were bed bound preoperatively, only 5% were still in bed postoperatively. Perioperative mortality rate was 5.8% and morbidity was 21%. The median survival for the cohort was 352 days (11.7 months). The radical surgery group had a median survival of 438 days and the palliative group 112 days (P = 0.003). Conclusion. Surgical treatment of spinal metastatic tumour is feasible with low mortality, an acceptably low morbidity and affords patients better quality of remaining life. Radical surgical excision has better outcome than palliative surgery in pain control and in neurological function rescue including regaining mobility and improvement in sphincter control

Purpose of the study: We report a series of 12 patients who underwent surgery in 2003 or 2004 for spinal shortening as treatment for thoracic or lumbar metastasis. Material and method: This series included seven females and five males, mean age 56.5 years (range 34–80 years). The operation was a resection of the vertebral body in a one-stage procedure. A simple posterior approach was used for two patients and a wider costotransversectomy approach was required for ten. Posterior fixation was installed with pedicle screws in the two vertebrae above and two below the resection. Mean operative time was 343 minutes (range 260–420 min). Mean blood loss was 2380 cc (range 600–5000). There were few surgery-related complications: one dural breach and one pulmonary breach. Results: The decision to undertake surgery was made on the basis of neurological problems in seven patients. All patients were Frankel class C, unable to walk. Among these patients, five died in less than six months. For the two survivors, they were scored 7 on the Tokuhashi scale. The remainder scored 5. For the two survivors, one recovered walking capacity (Frankel D) and the other achieved a normal status (Frankel E). The five other patients underwent surgery for pain related to a kyphosis callus threatening the cord. We used the Karnofsky and the Oswestry score to analyze outcome. The score did not regress in any of the patients after surgery. Three patients improved their score significantly. The three others had an unchanged score. The best correction of the kyphosis callus was obtained when the vertebral collapse was greater than 50%. The preoperative regional deformity was measured at 23.2° (range 15–35°) which postoperatively reached 0.5° (range 20 to −17°). Conclusion: This technique for spinal shortening appears to be a better alternative to anterior reconstruction, especially when the vertebral collapse is greater than 50%. In this context, this palliative surgery enables improved quality-of-life for a patient with often advanced disease

Purpose of the study: Balistic nerve injury is not common in civil medicine. We analyzed a series of 30 patients who underwent surgery for this type of injury suffered in the Gaza strip between 2002 and 2004. All patients presented paralysis of the sciatic nerve or one of its major branches. All injuries were caused by war weapons. Material and methods: The series included 28 men and two women, mean age 22 years (range 2.5–65). The injury had occurred more than one year earlier for 33% of patients. The injury was situated at the knee level in twelve patients and in the thigh in ten. Complete nerve section was observed in 12 patients and partial section in two. Loss of nervous tissue was significantly greater for lesions around the knee. Nineteen patients underwent surgery for: neurolysis (n=3), direct nerve suture (n=8) and nerve grafts (n=8). Eleven patients were reviewed at mean 13.7 months (range 3–30 months). There were no failures. Results of reinnervation of the tibial nerve territory were better than for the fibular nerve. Sixteen patients underwent palliative transfer for a hanging foot for more than six months: 15 transfers of the posterior tibial muscle through the interosseous membrane and hemitransfer of the Achilles tendon. Seven patients underwent Achilles tendon lengthening at the same time and five had a reinnervation procedure on the common fibular nerve. Results: Seven patients were reviewed with a mean follow-up of 1.8 years (range 4–30 months. None of the patients used an anti-equin orthesis. There were three cases of forefoot malposition. The overall Stanmore score was good at 75.4/100 (range 59–100). Discussion: High-energy ballistic trauma creates a specific type of injury. Nervous surgery can be indication early to favor spontaneous recovery. Palliative surgery for fibular lesions provides regularly good results. Conclusion: Nerve injuries due to ballistic trauma should be explored surgically because of the possibility of direct nerve repair. In addition, depending on the type of paralysis, reliable palliative surgery can be proposed

We report the case of an 80-year-old woman treated by palliative knee arthrodesis for metastases of the proximal left tibia secondary to bladder carcinoma, using percutaneous femortibial intramedullary arthrodesis nailing.

The technique provided a simple alternative to massive allografting, total joint prosthesis or amputation, with advantages of low morbidity, short operating time, minimal blood loss, immediate ambulation and weight bearing, relief of pain, restoration of independence, and ease of nursing care.

We are satisfied with the procedure of percutaneous femorotibial intramedullary nailing as a palliative treatment of proximal tibial metastases in an elderly patient.

We report the case of an eight-month-old girl who presented with a poliomyelitis-like paralysis in her left upper limb caused by enterovirus 71 infection. She recovered useful function after nerve transfers performed six months after the onset of paralysis. Early neurotisation can be used successfully in the treatment of poliomyelitis-like paralysis in children.

The aim of this study was to assess the significance of the extent and adequacy of the surgical margin on three outcome variables; survival, metastasis and local recurrence. We statistically analysed (Cox proportional hazards regression modelling) 279 consecutive patients who presented with soft tissue sarcoma without meta-static disease. They were treated by a single surgeon to a standard protocol in two centres. In terms of overall survival, the failure to achieve a wide surgical margin by contaminating the resection, led to an elevenfold increase in the relative death rate (p=0.04). However, where the margin was not contaminated (even if the margin was closer than 1 mm) then the overall survival rate was similar across all groups of patients with a clear margin up to 20 mm. A large margin greater than 20mm afforded the lowest risk to overall survival. The extent of the surgical margin was not statistically significant in the development of metastatic disease. The presence of a contaminated surgical margin and a narrow margin less than 1mm led to a significantly higher rate of local recurrence (p=0.02) A margin greater than 1 mm allowed a satisfactory outcome in terms of a low local recurrence rate and the extent of the margin up to 20mm was not statistically important. Patients who had radical resections did poorly and generally represent a group where palliative surgery was performed, and there was a very high relative metastasis and death rate. Our study provides statistically significant evidence that increasing width of resection improves local control and overall survival. However a narrow margin due to anatomical constraints such as bone or neurovascular structures does not significantly compromise patient outcome and this provides guidance for surgical decision making in limb salvage surgery
