Abstract
BACKGROUND Aseptic loosening is considered to be a rather uncommon complication in proximal humerus endoprosthetic replacement (PHER). However, patients with aseptic loosening often suffer severe bone loss, which poses a great challenge in following revision. Under this situation, a standard stemmed endoprosthesis is unavailable for revision limb salvage. Computer-aided design and 3D-printed personalized implants are an emerging solution for reconstructing complex bone defects. CASE PRESENTATION Here, we present a 67-year-old male who underwent PHER after tumor resection and developed aseptic loosening with severe periprosthetic osteolysis around the stem. Computer-aided design and 3D-printed personalized stem-plate composite was used for the precision revision of this patient. During the follow-up, encouraging results were observed, with good endoprosthetic stability and satisfactory limb function. CONCLUSION Computer-aid design and 3D-printed personalized stem-plate composite used in the present case could help to achieve good endoprosthetic stability and satisfactory limb function. This 3D-printed personalized stem-plate composite seems to be an effective method for the precise revision of PHER in patients with severe periprosthetic osteolysis. In addition, it also provides a novel method for similar revision surgery of other joints or primary endoprosthetic replacement with severe bone defects.

Implant cement spacer-a cost-effective solution for reconstruction of proximal humerus defects after tumor resection. J Clin Orthop Trauma 2021; 22:101574. [PMID: 34722144 PMCID: PMC8531854 DOI: 10.1016/j.jcot.2021.101574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 08/18/2021] [Accepted: 08/24/2021] [Indexed: 11/21/2022] Open
Abstract
The proximal humerus is a common location for both primary benign and malignant bone tumors and may require sacrificing deltoid muscles, axillary nerve and/or rotator cuff along with proximal humerus resection. Thus, post operatively shoulder movements are restricted. The main goals of reconstruction are to maintain a stable shoulder so that the function of elbow and hand can be optimized. Various reconstruction options are available after proximal humerus resection. We present our experience in using implant-cement spacers as a primary reconstruction option for limb salvage in the primary tumors of proximal humerus. All cases were retrieved from our prospectively maintained surgical database. 142 patients (96 males and 46 females) with a median age of 17.5 years (3-70 years) were operated with implant cement spacer between January 2006 and April 2019. Median follow up was 34 months (1-174 months). Functional outcome of the surgery was assessed in survivors by Musculoskeletal Tumor Society score (MSTS). Implant survival was assessed by Kaplan Meier analysis and competing risk analysis. On last follow up, out of 142 cases, 81 patients had died, 54 are alive and seven were lost to follow up. 18(13%) patients underwent revision surgery for symptomatic proximal migration, implant failure or infection. Four (2.8%) patients underwent forequarter amputation for local recurrence. The five years implant survival (IS) by Kaplan Meier analysis was 79.6% and as per competing risk analysis, the chances of implant revision are 12% and 18% at five and ten years respectively. Mean MSTS score in survivors was 71% (60-80%). Implant cement spacer is a cost-effective alternative for reconstruction of proximal humerus with revision rates and function comparable to other reconstructions in cases where deltoid, axillary nerve and/or rotator cuff are excised.

Abstract
Since the standard reconstructive option after large segmental resection of proximal humeral tumors remained controversial, we designed and applied plate-prosthesis composite (PPC) for this circumstance. The purposes of the study were to: compare the functional outcome, implant survival (IS), surgical risk of PPC with those of conventional proximal humeral prosthesis (PHP); and describe the design and reconstructive procedure of PPC.Twenty patients (11 males, 9 females), who received intraarticular proximal humeral resection without preservation of abductor mechanism, were included in this study, with a mean resection length accounting for 72.5% (range, 61.9-81.8%) of whole humeral length. According to the reconstructive options, we categorized patients into PPC group (9 patients) and PHP group (11 patients). PPC was a semi-custom-made endoprosthesis, with modular proximal part same as PHP and custom-made distal part including dumpy stem and composite lateral anatomic plate for distal humerus. The mechanical prosthetic complication was defined as the imaging evidence regardless of reoperation. The IS was defined as the time from surgery to the occurrence of mechanical prosthetic complication.The mean follow-up time was 40.1 months (range, 14-129). The Musculoskeletal Tumor Society 93 scores of PPC and PHP group showed no significant difference (73.3% vs 70.0%, P = .46). Compared to PHP group, PPC group showed significantly lower mechanical prosthetic complication rates (0 vs 45.4%, P = .03) and better IS (86.0 vs 59.3 ± 21.7 months, P = .028). Moreover, the comparison of surgical time (3.2 vs 3.3 hours, P = .60), blood loss (288.9 vs 376.4 mL, P = .15) and perioperative complication rates (11.1% vs 18.2%, P = .58) between 2 groups showed no differences.For reconstruction after large segmental resection of proximal humeral tumors, PPC achieved better IS while maintained similar functional outcome compared to conventional PHP without influencing the complexity and safety of surgery.

Abstract
Sarcomas, rare and heterogenous malignancies that comprise less than 1% of all cancers, have poor outcomes in the metastatic and refractory setting. Their management requires a multidisciplinary approach that consists of medical and surgical oncologists, radiation oncologists, and pathologists as well as ancillary support. In addition to systemic treatments, most patients will require surgical resection and radiation therapy, which mandates the use of the latest technologies and specialized expertise. Management guidelines have been developed in high-income countries, but their applicability in low-income countries, where resources may be limited, remains a challenge. In this article, we propose the best possible evidence-based practices specifically for income-constrained settings to overcome this challenge. In addition, we review the different methods that can be used in low-income countries to access new and expensive treatments, which often times carry prohibitive costs for these areas.

Abstract
Limb salvage surgery for malignant tumours of proximal humerus is an operative challenge, where the surgeon has to preserve elbow and hand functions and retain shoulder stability with as much function as possible. We treated 14 consecutive patients with primary malignant or isolated metastasis of proximal humerus with surgical resection and reconstruction by nail cement spacer. There were 8 females and 6 males, with a mean age of 28.92 years (range 16-51 years) and a mean follow-up of 30.14 months (range 12-52 months). The diagnosis was osteosarcoma in 8 patients, chondrosarcoma in 4 patients and metastasis from thyroid and breast carcinoma in 1 patient each. One of our patients had radial nerve neuropraxia, 1 developed inferior subluxation and 3 developed distant metastasis. Two patients died of disease and one developed local recurrence leading to forequarter amputation, leaving a total of 11 patients with functional extremities for assessment at the time of final follow-up which was done using the Musculoskeletal Tumour Society (MSTS) score. Though we were able to preserve the elbow, wrist and hand functions in all patients, the abductor mechanism, deltoid muscle and axillary nerve were not salvageable in any of cases. The mean MSTS score at the time of final follow-up was 19.09. Thus, proximal humeral reconstruction using nail cement spacer is a technical simple, cost-effective and reproducible procedure which makes it a reliable option in subset of patients where the functions around the shoulder cannot be preserved despite costlier prosthesis.

Abstract
Osteosarcoma and chondrosarcoma compose most of the primary malignancies of the shoulder. The literature lacks site-specific comparative analyses of these 2 major shoulder sarcomas. The purposes of this study were to describe the different characteristics of the 2 major sarcomas near the glenohumeral joint, examine differences in treatment outcomes, and evaluate the functional outcomes of limb salvage surgery. Thirty-two patients with osteosarcoma or chondrosarcoma who underwent a wide resection including the glenohumeral joint were enrolled in this study. The characteristics of tumor development and treatment, oncologic and functional outcomes, and factors affecting outcomes were compared between groups and with the literature. The results showed shoulder osteosarcoma developing similarly to the literature reports, whereas chondrosarcoma tended to be of a high histologic grade. Nonetheless, the osteosarcoma group had a poorer overall 5-year survival rate (53.0%) than the chondrosarcoma group (85.7%) or those in previous reports. The osteosarcoma group had a tendency toward a worse 5-year metastasis-free survival rate than the chondrosarcoma group (35.4% vs 75.0%, respectively), although the 5-year local recurrence-free survival rate was not significantly different between the 2 groups (75.0% vs 87.5%, respectively). Histologic grade, surgical stage, and chemotherapy affected the oncologic outcomes in univariate analysis, although not a single factor was independent in multivariate analysis. The functional outcomes were not significantly affected by clinical characteristics or surgical methods in patients who had undergone a wide resection including the glenohumeral joint.
