Is polypropylene mesh reconstruction functionally superior to non reconstructive group following total scapular resection? A retrospective analysis of 16 patients and a systematic review of the literature.

Background: Various reconstruction methods have been described in medical literature on scapular tumor resection depending on the type of resection and other factors. However the ideal method of reconstructions has been still debatable. The purpose of the current study was to assess whether polypropylene mesh reconstruction is superior as compared to non reconstructive group following total scapular resection.We also evaluated how our method of reconstruction fare as compared to reported reconstruction methods in the published literature. Methods: During 2014 to 2019; Total scapulectomy (Type III scapular resection) was performed in 16 patients for malignant tumor involving scapula bone. Reconstruction with polyprolene mesh(Group I) was performed in 56 % patient and non reconstruction technique (Group II) was observed in 44 % patient. The mean follow-up duration of current study was 28.3 months (range 13-67 months). The search method of PubMed and Cochrane databases provided 121 articles; of which 5 studies having 144 cases were utilised for final analysis. The reconstruction method used were dynamic humeral suspension (39.5%), non reconstruction method (35 %), scapular prosthesis (18 %) and static humeral suspension (5.5%). Results: The mean Musculoskeletal tumor society score (MSTS) of the study cohort was 19.8(0-23); and that in polyprolene mesh or static suspension method (Group I) and non reconstructive technique (Group II) was 67 % and 61% respectively. The emotional acceptance score in group I was 4.5 and that in group II was 4.2 points. There was no difference in the shoulder movements in both the groups. The mean surgical durations in group I and group II was was 186 min and 140 min respectively. The systematic review showed the mean Musculoskeletal tumor society score (MSTS) of dynamic suspension and non reconstruction method were 63 % and 63.5% respectively. The mean Musculoskeletal tumor society score (MSTS) of scapula prosthesis tended to be higher than those with dynamic suspension (77 % vs 65 %). Conclusions: The reconstruction with polypropylene mesh had better functional outcome and emotional acceptance as compared to non-reconstructive group in patients with total scapular resection surgery. The findings of systematic review suggest that; patients treated by reconstruction with polypropylene mesh and non-reconstructive group as compared to scapular prosthesis had limited shoulder movements with no difference in hand position, manual dexterity and lifting ability.

"Repair and Flap technique": A Retrospective Analysis of Single Stage Reconstruction Method for Treatment of Chronic Open Achilles Tendon Defect with Proximal Turndown Flap and Reverse Sural Flap.

BACKGROUND: Management of complex wounds of the lower extremity with concomitant Achilles tendon injury is a challenging situation for orthopaedic surgeons and plastic surgeons. The objective of the current study was to evaluate the clinical outcome of chronic open defects of the Achilles tendon with composite tissue loss. We have performed single stage reconstruction using the central segment of the proximal part of the Achilles tendon as turn-down flap and was covered immediately with reverse sural flap. MATERIALS AND METHODS: Between March 2017 and February 2020, five cases of chronic open composite Achilles tendon defects which were treated by a single stage reconstruction method of "Repair and Flap technique" were included in this study. The patient with the defect for more than 4 weeks duration and had substance loss of Achilles tendon together with loss of overlying skin and soft tissue was included the current study. RESULTS: All the flaps survived and healed well, providing stable coverage of the wound. The mean operative duration, including flap elevation, definitive flap inset and donor-site coverage was 98 min (range 90-120 min). Focal areas of skin graft loss were seen in two patients which healed with conservative management. The functional results evaluation was performed with The Achilles Tendon Total Rupture Score (ATRS). The mean Achilles Tendon Total Rupture Score (ATRS) was 70 (range 65-76). CONCLUSION: To conclude, use of proximal turned down flap and coverage with reverse sural flap can be opted as a first option for the management of chronic open wounds with composite defects of the Achilles tendon. "Repair and Flap technique" will be a useful method of reconstruction in centres with limited resources for microsurgical flap. However, a multicenter study with more number of patients are required to further analyse this method.

Impact of COVID -19 in cancer patients on severity of disease and fatal outcomes: A systematic review and meta-analysis.

BACKGROUND AND AIMSBACKGROUND: Currently there is limited knowledge on cancer and COVID-19; we conducted a systematic review and meta-analysis to evaluate the impact of cancer on serious events including ICU admission rate and mortality in COVID 19. METHODS: PubMed, Cochrane Central Register of Clinical Trials were searched on April 16, 2020, to extract published articles that reported the outcomes of cancer in COVID-19 patients. The search terms were "coronavirus" and "clinical characteristics" with no language or time restrictions. We identified 512 published results and 13 studies were included in the analysis. RESULTS: There were 3775 patients, of whom 63 (1·66%) had a cancer. The pooled estimates of ICU admission in COVID 19 patients with and without cancer were 40% versus 8·42%.The odds ratio of ICU admission rates between the cancer and non-cancer groups was 2.88 with a 95% CI of 1·18 to 7·01 (p = 0·026). The pooled estimates of death rate in COVID -19 patients with and without cancer were 20·83% versus 7·82%. The odds ratio of death rates between the cancer and non-cancer groups was 2.25 with a 95% CI ranging from 0·71 to 7·10 with p value of 0·166. The pooled prevalence of cancer patients was 2% (95 CI 1-4). CONCLUSIONS: Presence of cancer in COVID-19 leads to higher risk of developing serious events i.e. ICU admission, mechanical ventilation and mortality. The presence of cancer has a significant impact on mortality rate in COVID-19 patients.

Clinical and Oncological Outcome of Chondroblastic Osteosarcoma: A Single Institutional Experience.

INTRODUCTION: Chondroblastic osteosarcoma is an aggressive bone tumor characterized by chondroid matrix production with variable cellularity. This retrospective study is aimed to assess the demographic distribution, clinical behavior and oncological outcome of chondroblastic osteosarcoma. METHODS: 27 patients (14 males, 13 females) with chondroblastic osteosarcoma were included. The site of involvement included: proximal tibia (41%), distal femur (26%) and distal tibia (15%).The mean age of patients was 17 years (S.D: 6.9 years) (range 6-45 years). RESULTS: Painful swelling was the main complaint in all cases. Two patients were classified as Enneking III (lung) stage and the remaining patients had Enneking IIB stage. Post-neoadjuvant chemotherapy limb sparing surgery was performed in 70% of cases while in 30% of cases limb amputation was done. On histopathological examination of specimens mean necrosis was 64% (20-95%). Disease free survival (DFS) at 2 years was 46.4% and at 4 years was 27.9%. Median disease free survival was 24 ± 10.30 months. Overall survival (OS) at 2 years was 53.3% and at 4 years was 16.6%. Median overall survival is 28 ± 5.93 months. CONCLUSIONS: Chondroblastic osteosarcoma is associated with poor prognosis, high recurrence rate and metastatic potential with dismal long-term survival. Chondroblastic osteosarcoma is an aggressive histological variant of conventional osteosarcoma with frequent location around the knee joint, affecting young population. Chemotherapy with Methotrexate, Adriamycin, Cisplatin (MAP) regimen is a well-tolerated regimen, resulting in limb salvage surgery in majority of the cases.

Reconstruction with biological methods following intercalary excision of femoral diaphyseal tumors.

AIM: The aim of this study was to assess outcomes of biological (nonvascularized fibula grafts and extracorporeal irradiated autologous bone grafts) methods used for reconstruction of intercalary defects after resection of femoral diaphyseal tumors. MATERIALS AND METHODS: This study included 28 patients who had undergone intercalary resection in femoral diaphyseal tumors between 2011 and 2016. The mean follow-up period was 24 months (range 12-57 months). RESULTS: The mean union time for diaphyseo-diaphyseal union was 10.5 and 11 months in nonvascularized fibula group and extracorporeal radiotherapy (ECRT) group, respectively. The mean union time for metaphyseo-diaphyseal union was 6.5 months in both nonvascularized fibula and ECRT groups. Six patients had distant metastasis, and one patient had local recurrence. The mean Musculoskeletal Tumor Society score was 28 at the last follow-up. Two patients had surgical site infection in the nonvascularized fibula group. Implant failure was found in one patient of the ECRT group requiring revision surgery. Three patients had nonunion (two from the nonvascularized fibula group and one from the ECRT group). CONCLUSION: The present study indicates that the biological reconstruction modalities provide good functional outcomes in diaphyseal tumors of femur. Nonvasularized fibula and ECRT-treated autografts reconstruction provides good results, and union timing is comparable. The outcomes of the current study are promising as compared to the results in the reviewed literature. The reconstruction method depends on the resources available at the oncological center and the conversance with the method of the treating surgeon.

A Prospective Study of the Functional Outcome of Anterior Cervical Discectomy With Fusion in Single Level Degenerative Cervical Disc Prolapse.

INTRODUCTION: Cervical spondylotic myelo-radiculopathy is a form of spinal cord dysfunction syndrome and usually accompanies age related degeneration of the spine. AIM: To determine the functional outcome of anterior cervical discectomy with fusion and plating in single level degenerative cervical disc prolapse. MATERIALS AND METHODS: A total of 20 patients diagnosed with degenerative single level cervical disc prolapse who presented to the Department of Orthopaedic Surgery, Justice KS Hegde Charitable Hospital, Mangalore from the period of November 2012 to May 2014 were enrolled in the study. Complete clinical and radiological evaluation of the patients was done. A trial of conservative management was tried in all these patients for a period of two months. They were taken up for surgery only when conservative management had failed. Scoring of neck function before the surgery was done as per the Modified Japanese Orthopaedic Association (MJOA) score. All patients underwent anterior cervical discectomy and fusion (ACDF) with tricortical iliac crest bone grafting. Fixation was performed with titanium locking cervical plates. All patients were reviewed at 6 weeks and 6 months postoperatively. Assessment of neck function was done as per the MJOA scoring during all the reviews. Radiographic assessment was also done during all the reviews. The complications noted were documented. The statistical analysis was done using percentages; the arithmetic mean was calculated using SPSS software (version 16.0). RESULTS: Amongst the 20 patients included in the study, 1 patient died postoperatively due to oesophageal rupture. of the remaining 19 patients reviewed and followed up, all of them had improvement of symptoms and were reported to be in the 'mild category' as per the MJOA score. One patient developed dysphonia, in the immediate postoperative period due to recurrent laryngeal nerve palsy which recovered in a period of three months postoperative. CONCLUSION: Single level anterior cervical discectomy with fusion and anterior cervical plating for degenerative cervical disc prolapse with or without myelo-radiculopathy is an effective and safe surgical procedure with minimal complication rate.
