A Size-Based Criteria for Flap Reconstruction After Thigh-Adductor, Soft-Tissue Sarcoma Resection.

BACKGROUND: Resection of soft-tissue sarcomas from the adductor compartment is associated with significant complications. Free/pedicled flaps often are used for wound closure, but their effect on healing is unclear. We compared wound complications, oncologic, and functional outcomes for patients undergoing flap reconstruction or primary closure following resection of adductor sarcomas. METHODS: A total of 177 patients underwent resection of an adductor sarcoma with primary closure (PrC) or free/pedicled flap reconstruction (FR). Patient, tumor, and treatment characteristics were compared, as well as wound complications, oncologic, and functional outcomes (TESS/MSTS87/MSTS93). To examine the relative benefit of flap reconstruction, number needed to treat (NNT) was calculated. RESULTS: In total, 143 patients underwent PrC and 34 had FR, 68% of which were pedicled. There were few differences in demographic, tumor, or treatment characteristics. No significant difference was found in the rate of wound complications. Length of stay was significantly longer in FR (18 days vs. PrC 8 days; p < 0.01). Oncologic and functional outcomes were similar over 5 years follow-up. Uncomplicated wound healing occurred more often in FR compared with PrC for tumors with ≥15 cm (NNT = 8.4) or volumes ≥ 800 ml (NNT = 8.4). Tumors ≤ 336 ml do not benefit from a flap, whereas those > 600 ml are 1.5 times more likely to heal uneventfully after flap closure. CONCLUSIONS: Although flap use prolonged hospitalization, it decreased wound healing complications for larger tumors, and in all sized tumors, it demonstrated similar functional and oncologic outcomes to primary closure. Our size-based treatment criteria can help to identify patients with large adductor sarcomas who could benefit from flap reconstruction. LEVEL OF EVIDENCE III: (Retrospective cohort study).

Constrained or unconstrained shoulder replacement for musculoskeletal tumor resections?

BACKGROUND: Many options exist for reconstructing the shoulder after large bony resections of the proximal humerus. One of the more widely used is endoprosthetic replacement. Proximal migration of unconstrained hemiarthroplasty articulations may cause difficulties particularly in the setting of loss of the rotator cuff and/or deltoid musculature. To attempt to overcome these issues, a fixed-fulcrum constrained reverse shoulder replacement option may be considered. METHODS: A retrospective review of prospectively collected data from the Queensland Bone and Soft Tissue Sarcoma Service was undertaken to compare the function, implant survivorship, and reoperation rate of constrained reverse and unconstrained hemiarthroplasty-type endoprostheses in patients with tumors. RESULTS: We retrospectively reviewed data on 41 consecutive proximal or total humeral endoprosthetic replacements undertaken between January 2003 and July 2018. One patient was excluded as lost to follow-up prior to 24 months. There were 21 unconstrained implants and 19 constrained shoulder replacements (Stanmore Modular Endoprosthesis Tumour System with Bayley-Walker articulation). Proximal migration of the unconstrained hemiarthroplasty articulation occurred in 8 patients (38%), and dislocation or failure of the constrained mechanism occurred in 5 (26%). Reoperation for implant-related issues was required in 5 patients in the constrained group and none in the unconstrained group. Of the 18 patients alive at the time of review, 12 provided functional scores. The mean follow-up period for surviving patients was 4.2 years (standard deviation, 2.7 years), with a minimum of 2 years' follow-up. Functional scores were similar between the 2 groups. CONCLUSION: Constrained reverse prostheses were associated with a higher reoperation rate in this series without any functional benefit compared with unconstrained hemiarthroplasty-type articulations. We favor the use of unconstrained hemiarthroplasty-type endoprostheses for reconstruction after resection of destructive lesions of the proximal humerus.

Telehealth in paediatric orthopaedic surgery in Queensland: a 10-year review.

BACKGROUND: Telemedicine is a patient consultation method commonly available to patients in rural and remote areas throughout Australia. Its use in paediatric orthopaedics has been rarely described. The primary aim of this study was to identify the patient cohort accessing the orthopaedic paediatric telehealth service through the Royal Children's Hospital Queensland, so as to better allocate this resource. The secondary aims were to identify the orthopaedic conditions the patients utilizing this service suffered and to follow-up on treatment outcomes to potentially assess clinical benefit. METHOD: A retrospective review of prospectively collected data of paediatric orthopaedic patients consulted using telehealth at the Royal Children's Hospital, Queensland over a 10-year period between January 2004 and September 2012 was conducted. RESULTS: One hundred and twenty-six patient records were assessed with a mean age of 6 years. Results showed that 40% of patients seen using telehealth in paediatric orthopaedics had documented cerebral palsy, an intellectual disability or congenital syndrome. Common paediatric orthopaedic conditions were seen, with lower limb malalignment being the most common presenting complaint. About 58% of patients were seen exclusively via telehealth and did not require in-person consultation or operative therapy. CONCLUSION: We found that the orthopaedic telepaedriatic consultation service at the Royal Children's Hospital reviewed a large proportion of patients with a known disability. We believe there is a role for telehealth medicine for all patients; however, we propose that even greater benefit can be obtained from telehealth consultation in patients with a disability where the cost and inconvenience of patient transport is considerably increased.
