Background: Non-graftable or composite defect reconstruction represents a major challenge to the reconstructive surgeon, with many wounds requiring local flap or free microvascular tissue transfer approaches. The recent advent of synthetic skin substitutes such as Biodegradable Temporizing Matrix (BTM) have revolutionized the management of complex defects including those caused by burns, trauma and infection, with low-morbidity and low-complexity surgery. However, limited data exist supporting their use in cancer reconstruction in Australia.

Objectives: To identify the revision rate of internal fixation and hemiarthroplasty in patients 60 years or older with Garden I or II hip fractures and to identify risk factors associated with each method.
Purpose: The purpose of this study was to assess survival rate, functional and radiological outcomes when using a hydroxyapatite-ceramic fully coated primary femoral stem in revision total hip arthroplasty.
Methods: Patients who underwent revision total hip arthroplasty using the Furlong hydroxyapatite-ceramic (HAC)-coated (Joint Replacement Instrumentation Ltd., Sheffield, UK) primary stem were retrospectively identified between 2013 and 2017.
Objective: Autologous fat grafting of the velopharynx has been well described for the treatment of velopharyngeal insufficiency (VPI), with most studies purporting it as a technique with low morbidity useful in the treatment of mild VPI. Prompted by 3 cases of obstructive sleep apnea (OSA) following fat grafting of the velopharynx, we undertook a review of the outcomes of this procedure at our unit.
Design: Retrospective case series.
Background: Many exchangeable neck hip systems have been withdrawn because of fretting corrosion at the neck/stem coupling.
Method: Our prospective randomized study evaluating stem stability (Roentgen stereophotogrammetric analysis, dual-energy x-ray absorptiometry) and clinical outcomes between the K2/Apex hip systems was ceased early because of a withdrawal of the stems which had an unfavorably high early revision rate reported in the Australian Orthopaedic Association National Joint Registry (9.3% at 3 years).
Tranexamic acid (TXA) has been shown to reduce perioperative blood loss in elective lower limb arthroplasty surgery. There are potentially even greater physiological benefits in minimising blood loss in hip fracture surgery, however limited evidence exists for TXA use in hemiarthroplasty surgery. This study investigates the effect of TXA use on postoperative transfusion rates and haemoglobin (Hb) levels specifically following hemiarthroplasty surgery for hip fractures.

- The study aimed to evaluate subsidence, rotation, and clinical scores of two types of cementless femoral stems (K2 and Apex) in hip surgeries.
- A total of 260 patients were involved, monitored over 2 years using RSA (Roentgen Stereophotogrammetric Analysis) and clinical scoring systems.
- Results showed high Oxford Hip scores for both stems, minimal subsidence and rotation, no significant clinical differences between the stems, and a low revision rate of 0.8%, indicating promising long-term outcomes.
Background: The AGC knee is one of the most widely used knee replacements in the world with good survivorship in national joint registries, including the Swedish within which it remains the gold standard of risk.
Purpose: However, there are few long term survivorship reviews from the centre other than those affiliated with the designer that also offer any insight into functional outcome. In this review, we present the results of one of the largest non-designer, medium- to long term follow-ups of the AGC knee replacement.
Background: In our experience results of the Oxford unicompartmental knee replacement have not been as good as had been expected. A common post operative complaint is of persistent medial knee discomfort, it is not clear why this phenomenon occurs and we have attempted to address this in our study.
Methods: 48 patients were retrospectively identified at a mean of 4.
Occupationally related bilateral calcific tendonitis of Flexor carpi ulnaris: case report.
J Orthop Surg Res
August 2009
We present a case of bilateral calcific tendonitis of the Flexor Carpi Ulnaris attributable to repetitive wrist action which was occupationally related. This was treated conservatively with avoidance of aggravating movement, resting splints and anti inflammatory medication when acute flare ups occurred. Since avoidance of repetitive strain on the wrists he has had no further flare ups in over 2 years.

- A 17-year follow-up study observed 44 clubfeet that were surgically corrected, categorizing them as mild, moderate, or severe before surgery.
- Most moderate and severe cases received a posteromedial release after attempting conservative treatment, with an overall mean Ponseti score of 83.9, indicating good outcomes.
- Results showed that severely deformed feet had better functional outcomes when treated surgically before 3 months of age compared to those treated later.
