Long-term results of intralesional curettage and cryosurgery for treatment of low-grade chondrosarcoma.

J Bone Joint Surg Am. 2013 Aug 7;95(15):1358-64

Authors: Meftah M, Schult P, Henshaw RM

Abstract
BACKGROUND: Data regarding outcomes following intralesional curettage and cryosurgical treatment of low-grade chondrosarcoma of bone are limited. The aim of this study was to assess the long-term oncologic and functional outcomes of two different cryosurgery techniques.
METHODS: Forty-three low-grade chondrosarcoma lesions (in forty-two patients) were treated with intralesional curettage and cryosurgery from June 1983 to October 2006. Eleven lesions were treated with cryoprobes and thirty-two were treated with the modified direct-pour Marcove technique. The mean patient age was 44.9 ± 11.3 years (range, 21.8 to 66.4 years), and the mean duration of follow-up was 10.2 ± 4.6 years (range, five to 22.5 years). Indications for treatment included a radiographic appearance consistent with a cartilage tumor with evidence of aggressive behavior. Pearson correlation and multivariate analyses were used to evaluate the relationships between predictive factors (including lesion size, soft-tissue extension, and location, patient age, cortical erosion, and presence of preoperative pain) and outcomes.
RESULTS: The mean overall Musculoskeletal Tumor Society (MSTS) score was 26.5 ± 3.1 (range, 17 to 30). There were four local recurrences, all in patients

Lower limb amputation and rehabilitation in total joint arthroplasties in the ipsilateral limb.

Prosthet Orthot Int. 2013 Aug 7;

Authors: Shi J, Wang S, Wei Y, Wu J, Chen F, Huang G, Chen J, Wei L, Jiang J, Xia J

Abstract
Background:Degenerative joint disease is not uncommon in amputees and reaches the orthopedic surgeon when all other conservative methods to manage these patients have failed. Several case reports describing hip and knee arthroplasties in patients with hip and knee joint diseases or fractures with the distal part amputated, either in the contralateral or ipsilateral limb, exist in literature.Objective:This article focuses only on total knee and total hip arthroplasty in amputees who have had severe osteoarthritis of the ipsilateral hip and knee joints.Study design:Literature review.Method:Literature search in database and summary of all the cases.Results:All narratives indicate positive outcomes with improvement in physical function and quality of life.Conclusion:The reports suggest that slight modifications in surgical procedure and in the rehabilitation protocol as compared to other patients with joint arthroplasties can alleviate pain and make such patients ambulatory and gain maximum range of motion. Therefore, it appears that careful preoperative evaluation and planning tailored to suit individual cases maximizes postoperative good end results beneficial to the patients regardless of age or cause of osteoarthritis.

Use of a load cell and force-moment curves to compare transverse plane moment loads on transtibial residual limbs: a preliminary investigation.

Prosthet Orthot Int. 2013 Aug 6;

Authors: Neumann ES, Brink J, Yalamanchili K, Lee JS

Abstract
Background and aim:The objective of this study was to demonstrate how a load cell and force-moment curves can be used outside of a gait lab to directly measure and evaluate the transverse plane loading moment on transtibial residual limbs.Technique:A load cell was attached distally to the socket of three transtibial amputees who walked a straight path and a circle of 3.048-m diameter with the prosthetic foot both inside and outside the curved path.Discussion:Compared to straight path walking, transverse plane moment decreased when the foot was on the outside of the curved path. When the foot was on the inside, the moment did not exceed that for straight path walking for two participants; maximum transverse moment was approximately 0.15 N m/kg of body mass. Force-moment curves indicated that each participant's gait was unique, but underlying similarities were observed with respect to each of the three conditions.Clinical relevanceA load cell in conjunction with curved and straight path walking and force-moment curves can be used outside of a gait lab to measure and examine the transverse plane loading on the residual limb.

Validation of the Brazilian Version of the Musculoskeletal Tumor Society Rating Scale for Lower Extremity Bone Sarcoma.

Clin Orthop Relat Res. 2013 Aug 6;

Authors: Rebolledo DC, Vissoci JR, Pietrobon R, de Camargo OP, Baptista AM

Abstract
BACKGROUND: The Musculoskeletal Tumor Society (MSTS) rating scale is an English-language instrument used worldwide to assess functional evaluation of patients with musculoskeletal cancer. Despite its use in several studies in English-speaking countries, its validity for assessing patients in other languages is unknown. The translation and validation of widely used scales can facilitate the comparison across international patient samples.
OBJECTIVES/PURPOSES: The objectives of this study were (1) to translate and culturally adapt the MSTS rating scale for functional evaluation in patients with lower extremity bone sarcomas to Brazilian Portuguese; (2) analyze its factor structure; and (3) test the reliability and (4) validity of this instrument.
METHOD: The MSTS rating scale for lower limbs was translated from English into Brazilian Portuguese. Translations were synthesized, translated back into English, and reviewed by a multidisciplinary committee for further implementation. The questionnaire was administered to 67 patients treated for malignant lower extremity bone tumors who were submitted to limb salvage surgery or amputation. They also completed a Brazilian version of the Toronto Extremity

Chronic expanding hematoma in the stumps of persons following transfemoral amputation: A report of two cases.

Prosthet Orthot Int. 2013 Jul 25;

Authors: Takakura T, Mikami T, Nishioka Y, Nemoto A, Mizuochi K

Abstract
Background:Two persons presented with severe stump pain following transfemoral amputation.Case description and methods:A 21-year-old female and a 31-year-old male with transfemoral amputation were ambulatory with prostheses and suffered from severe stump pain caused by the presence of masses around the tip of the bone stump. From the clinical courses, imaging studies, and the intraoperative findings, the masses were diagnosed as a relatively rare condition known as chronic expanding hematoma.Findings and outcome:The two patients were treated successfully with surgical resection. The hematomas were soft cystic masses with a thick capsule containing old blood clots and serous fluid. There were no pathological signs of malignancy. After surgical treatment, the patients achieved walking without stump pain.Conclusion:Although chronic expanding hematoma is a rare condition, it should be considered as a possible cause of stump pain.Clinical relevanceStump pain is caused by many conditions. Although chronic expanding hematoma is a rare condition, it should be considered as a possible cause of stump pain.

The Phosphaturic Mesenchymal Tumor: Why is Definitive Diagnosis and Curative Surgery Often Delayed?

Clin Orthop Relat Res. 2013 Jul 19;

Authors: Ledford CK, Zelenski NA, Cardona DM, Brigman BE, Eward WC

Abstract
BACKGROUND: Tumor-induced osteomalacia is a paraneoplastic syndrome resulting in renal phosphate wasting and decreased bone mineralization. Phosphaturic mesenchymal tumors represent a rare etiology of tumor-induced osteomalacia. Nonspecific symptoms of fatigue, bone pain, and musculoskeletal weakness make the diagnosis elusive and lead to a delay in surgical treatment.
QUESTIONS/PURPOSES: In this case series, the following three questions were asked: (1) How do the clinical presentation and features of phosphaturic mesenchymal tumors delay the diagnosis? (2) What is the clinical course after surgical treatment of phosphaturic mesenchymal tumors? (3) How frequently do phosphaturic mesenchymal tumors recur and are there factors associated with recurrence?
METHODS: This study retrospectively reviewed the cases of five adults diagnosed and treated for phosphaturic mesenchymal tumors. Patients were identified through an internal orthopaedic oncology database with clinical, surgical, and histologic data obtained through a systematic chart review.
