Background: In light of impending physiotherapy workforce shortages in Australia and updates to career progression pathways for physiotherapists internationally, it is important to understand the beliefs and considerations that underpin decisions to pursue career development opportunities from the perspective of physiotherapists.

Purpose: To investigate physiotherapists' beliefs, motivations and perceived barriers toward career development opportunities, and explore influences which impact the decisions regarding whether and how to undertake career development in physiotherapy.

Methods: Qualitative study using one-on-one semi-structured interviews.

Soft tissue defects over the dorsal finger are common and may result from trauma, burns, or surgical management of infections and tumors. We present a case where a bilobed flap was used for the reconstruction of a soft tissue defect dorsal to the proximal phalanx of the ring finger and discuss the design of this flap. The defect was secondary to a collar button abscess of the right third webspace and the surgical debridement required to control the infection.

Introduction: Previous studies have highlighted the association between insurance status and poor outcomes after surgical treatment of sarcomas in the United States.1-3 It is unclear how much of this disparity is mediated by confounding factors such as medical comorbidities and socioeconomic status and how much can be explained by barriers to care caused by insurance status.

Methods: Surveillance, Epidemiology, and End Results-Medicare linkage data were procured for 7,056 patients undergoing treatment for bone and soft-tissue sarcomas in the extremities diagnosed between 2006 and 2013.

Case: A 9-year-old girl developed a physeal bar after flexible nailing for a proximal radius fracture. The patient presented 2 years after initial injury with gross deformity of the wrist with confirmed physeal bar. The patient underwent physeal bar resection, cement interposition, and corrective osteotomy with improvement of radial height, wrist deformity, and function.

Background: Malignancy in giant cell tumor of bone (GCTB) is a rare tumor with relevant literature being sparse. In primary malignant GCTB, distinct areas of benign GCTB are juxtaposed with high-grade sarcoma, while in secondary malignant GCTB sarcoma occurs at the site of previously managed GCTB. This study assesses the distinguishing characteristics of patients with this condition, the time interval for development of secondary malignant GCTB, the outcome of treatment, and explores factors associated with oncologic outcomes.

Brain metastases are a rare occurrence in patients with sarcoma. The prognosis for patients is poor, and treatment can contribute to considerable morbidity. We sought to examine the experience of our institution in managing these patients over a period of 17 years.

Background: High-grade surface osteosarcoma is an extremely rare subtype of osteosarcoma. The treatment outcome for this tumor varies in different centers.

Methods: This was a retrospective study of high-grade surface osteosarcoma; clinical, radiological, and histological materials were reviewed.

Management of malignant peripheral nerve sheath tumours (MPNSTs) is primarily surgical, involving surgical resection with wide margins, and frequently radiation therapy. When a MPNST involves a major peripheral nerve, wide resection leads to significant distal neurologic deficits. A patient who underwent resection of a MPNST involving the median nerve above the elbow is presented.

 Numerous surgeries have been described for osteoarthritis of the trapeziometacarpal (TMC) joint. We describe the senior author's experience with his technique of concurrent arthroplasty of the TMC joint, and carpal tunnel release (CTR) via a radial approach.  The study is a case series of patients managed over a 3-year period.

Background: Periosteal osteosarcoma is a rare surface-based variant with a lower propensity to metastasis and better prognosis than conventional osteosarcoma. The literature supporting survival benefit with adjuvant chemotherapy is lacking. Our institutional practice is for chemotherapy to be offered to patients with high-grade disease.

Background: Resection of sacral chordomas is challenging. The anatomy is complex, and there are often no bony landmarks to guide the resection. Achieving adequate surgical margins is, therefore, difficult, and the recurrence rate is high.

Background: Many techniques have been described for reconstruction after distal radius resection for giant cell tumor with none being clearly superior. The favored technique at our institution is total wrist fusion with autogenous nonvascularized structural iliac crest bone graft because it is structurally robust, avoids the complications associated with obtaining autologous fibula graft, and is useful in areas where bone banks are not available. However, the success of arthrodesis and the functional outcomes with this approach, to our knowledge, have only been limitedly reported.

Background: Giant cell tumor (GCT) of bone is a rare, benign, aggressive bone tumor with an unusual capacity to metastasize to the lung. It was the goal of this study to identify patient and treatment-specific variables associated with the development of pulmonary metastases of GCT of bone.

Methods: From 1980 to 2009, 291 patients with benign GCT of bone were treated at our institution, and 167 were followed for at least two years.

Visualization of the three-dimensional nature of a Hill-Sachs lesion during osteoarticular allografting via an anterior approach is challenging and makes fashioning of an appropriately sized shape-matched graft difficult. A technique using bone wax to aid in templating the size and shape of the Hill-Sachs lesion for grafting is described.

Purely chondral fractures of the distal femur associated with patellar dislocation are uncommon, and treatment varies from fixation to debridement and marrow stimulation techniques. The unusual case reported here involves an adolescent who underwent fixation of a purely chondral fracture involving a large weight-bearing portion of the lateral femoral condyle. Chondral fracture healing was confirmed on follow-up magnetic resonance imaging and arthroscopic examination.
