1.Pollicization: The Concept, Technical Details, and Outcome.
Clinics in Orthopedic Surgery 2012;4(1):18-35
Pollicization substitutes a functioning finger for a deficient thumb. The most indication is thumb hypoplasia with absence or instability of the carpometacarpal joint. However, there are additional causes that may negate thumb function, such as trauma, macrodactyly, multi-fingered hand, and a mirror hand. The technique of pollicization represents a consolidation of contributions from surgeons over the last 100 years. A meticulous stepwise approach from incision to closure is necessary to optimize outcome. Following pollicization, cortical plasticity and motor relearning play a pivotal role in function following pollicization with connections and adjacent sprouting from nearby cortical and/or subcortical territories. Occupational therapy is necessary to encourage large object acquisition followed by smaller objects and ultimately fine pinch. Pollicization is more reliable in patients with isolated thumb hypoplasia and a mobile index finger with robust extrinsic and intrinsic muscle-tendon units compared to and patients with radial forearm deficiencies and diminished index mobility.

Wrist pain is a common presentation to the general practitioner and emergency department. Most cases are simple to treat, and pain frequently resolves with conservative treatment. However, there are certain conditions, such as scaphoid nonunion and Kienböck's disease, where delayed diagnosis and treatment can result in long-term deformity or disability. This article covers the various causes of wrist pain, recommendations on how wrist pain should be assessed, as well as details some of the common conditions that warrant specialist referral.

4.Outcome of posterior wall blowout in anterior cruciate ligament (ACL) reconstruction via anteromedial portal approach: A retrospective research in 20 patients with 6 years follow-up.

PURPOSE:
To evaluate the clinical outcome in patients who received anterior cruciate ligament (ACL) reconstruction via anteromedial portal with or without posterior wall blowout.
METHODS:
Twenty patients with ruptured ACL, who have received ACL reconstruction via anteromedial portal between Apr 2012 and Oct 2013 were enrolled. According to the conditions of posterior wall, the patients were divided into 2 groups: posterior wall blowout group (10 patients) and posterior wall intact group (10 patients). The median follow up time were 63 (range 19-75) months and 60.5 (range 25-64) months in the 2 groups respectively. The clinical outcome was evaluated by knee joint physical examination, magnetic resonance imaging (MRI), the International Knee Documentation Committee (IKDC) 2000 subjective score, Lysholm score, Tenger score, difference of thigh circumference, KT-2000 and Biodex isokinetic dynamometer system.
RESULTS:
No significant differences were found in terms of the IKDC score, Lysholm score, Tegner score, Lachman test positive rate or Pivot Shift test positive rate between the two groups. In KT-2000 and Biodex isokinetic dynamometer tests, the difference of muscle strength between affected knees and unaffected knees in posterior wall blowout group was not significant less than that of posterior wall intact group (p > 0.05). In addition, there is no statistical difference between the two groups in signal/noise quotient (SNQ) of the graft (p > 0.05) in post operative MRI.
CONCLUSION
Blowout of posterior wall in ACL reconstruction via anteromedial portal does not affect the clinical outcome as long as reliable fixation is taken intraoperatively.

Increasing incidence of musculoskeletal injuries coupled with limitations in the current treatment options have necessitated tissue engineering and regenerative medicine- based approaches. Moving forward from engineering isolated musculoskeletal tissues, research strategies are now being increasingly focused on repairing and regenerating the interfaces between dissimilar musculoskeletal tissues with the aim to achieve seamless integration of engineered musculoskeletal tissues. This article reviews the state-of-the-art in the tissue engineering of musculoskeletal tissue interfaces with a focus on Singapore's contribution in this emerging field. Various biomimetic scaffold and cellbased strategies, the use of growth factors, gene therapy and mechanical loading, as well as animal models for functional validation of the tissue engineering strategies are discussed.

INTRODUCTIONBoth conservative and operative management have been described in the literature for the management of chronic Achilles tendon ruptures with surgical management generally having more favourable results. In our institution, the favoured reconstructive technique was the use of 2 turndown tendon fl aps fashioned from the proximal Achilles tendon augmented by a tenomyodesis of the flexor hallucis longus. The purpose of this study was to assess the clinical outcome of all patients who underwent this procedure.
MATERIALS AND METHODSFrom the records, a total of 9 patients underwent the above-mentioned procedure of whom 6 patients had complete data collection sets [including SF-36, Visual Analogue Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scores, ankle range of motion (ROM), presence of residual symptoms and complications] at 2 years of follow-up.
RESULTSOur results showed an average AOFAS Ankle-Hindfoot score of 94.2, VAS of 0 in all but 1 patient, and generally high scores (75-96) in all 8 domains of the SF-36 questionnaire. Patient satisfaction was also rated to be high from the surgical procedure.
CONCLUSIONWe submit that the procedure adopted at our institution is able to reproduce satisfactory results with low morbidity in patients with this challenging condition.
