Total humeral replacement is a complex surgery that requires many challenges to overcome such as the weight of the implant material and the shoulder function due to extensive resection of the rotator cuff. Improvements in implants material that is lighter than usual can lead to higher surgery success rates. We present a patient who was diagnosed with osteosarcoma of the right humerus. The patient received 2 cycles of MAP chemotherapy (included: doxorubicin, cisplatin, and methotrexate) before surgery. He underwent radical resection of osteosarcoma and total humerus replacement with a modified total humeral material. The purpose of this improvement was to reduce the implant’s weight and to improve postoperative recovery. Six months after the surgery, the weight-bearing ability of the patient’s shoulder within a wide range of movement has restored; the shoulder, elbow, and hand can move in a controlled way. Despite the short postoperative follow-up time, the improvement in the modified technique has brought many positive results. Total humerus replacement, which combines the reverse shoulder prosthesis, elbow prosthesis, and polyetheretherketone, is an appropriate solution for patients with osteosarcoma of the humerus instead of custom-made humerus megaprosthesis.

Over a 4-year period, 218 mallet fractures in 211 adult patients were treated using a custom-made thermoplastic splint. Clinical results were collected prospectively, including the visual analogue score for pain, the range of motion and extensor lag, and the Patient Evaluation Measure (PEM). The joints were congruent in 168 and subluxed in 50. There were no differences in range of movement, extensor lag or PEM associated with articular subluxation or the size of the articular fragment. Pre-existing joint degeneration did not influence outcome. Non-surgical treatment demonstrates predictably good outcomes regardless of fragment size or subluxation in most patients and should be considered when discussing treatment for patients with bony mallet fractures.

The wide range of skin tones in the Asian population presents a challenge when colour-matching hand and finger prostheses. It requires that the prostheses be custom-made to better match the wide variations. We have developed a finger and hand prosthesis using a multi-layered moulding technique incorporating a colour-matching procedure capable of reproducing the colour tones and life-like appearance of the skin. Between 1990–1994, we have fitted these prostheses to a total of 109 patients. In evaluating the colour-match of their prostheses, 84% of the patients fitted with hand prostheses and 78% of those fitted with finger prostheses had a good to excellent match. This paper discusses some of the challenges we face in colour-matching hand and finger prostheses in the Asian population.

Prefabricated ICEROSS (Icelandic Roll On Silicone Socket) sockets have been in use in Iceland since early 1986. Use of custom-made silicone sockets began several years earlier, and a paper devoted to the subject was presented at the 1984 AOPA Assembly by the author of this article. The ICEROSS system is primarily used for suspension. At the same time the author believes it considerably improves the weight-bearing capability of the prosthesis and the interface between prosthesis and user. After being turned inside out and rolled over the stump, the silicone sleeve forces skin in a distal direction, stabilising soft tissue and minimising pistoning. Both prosthetist and user may experience some problems initially, although most can be overcome by careful socket design and skin care.

Background: Different treatment options exist for dynamically unstable purely ligamentous syndesmotic injury, including surgery, walking boot, brace and taping. Objective: The main purpose of this study was to evaluate the effect of high-ankle sprain taping (ring taping) on syndesmotic stability in various ligament conditions when axial loading is applied. Methods: This controlled cadaveric laboratory study included ten cadaveric specimens installed in a custom-made device applying 750N of axial loading in order to simulate weight-bearing. Sectioning of syndesmotic ligaments, AiTFL and IOL, was done sequentially and CT scan images were taken with and without high-ankle sprain taping. A validated measurement system consisting of 3 lengths and 1 angle was used. Results were compared with Wilcoxon tests for paired samples and non-parametric data. Results: In every ligament condition (intact vs. cut), no statistically significant difference was observed between specimens, with or without high-ankle sprain taping and with or without axial loading. When the data from ankles with AiTFL and IOL ruptures were compared, the mean for length “b” without axial loading was 7.19 (±2.17), compared to 7.20 (±1.98) with axial loading (p-value = 0.905). With taping and the leg still in axial loading, the value was 7.17 (±2.09) (p-value = 0.721), which is not statistically significant. Conclusion: It is impossible to conclude regarding high-ankle sprain taping’s capacity to maintain syndesmosis congruity because no significant difference was observed, regardless of condition. The most important finding is that high-ankle sprain taping did not cause malreduction of the injured syndesmosis. Level of Evidence: Level V cadaveric study

AimTo compare the interpretation of toe touch weight bearing (TTWB) and partial weight bearing (PWB) among orthopaedic surgeons, rehabilitation professionals and patients.Methodology78 consultant and middle-grade orthopaedic surgeons in the UK completed a questionnaire. 64 rehabilitation professionals (including physiotherapists) at Defence Medical Rehabilitation Centre Headley Court were also recruited. Both groups provided their interpretation of TTWB and PWB as a percentage of total body weight (%TBW). Each rehabilitation professional, then applied what they interpreted to be TTWB and PWB using a Lasar Posture weighing device. The predicted values were compared with the actual values demonstrated.ResultsThere was no significant difference between orthopaedic surgeons and rehabilitation professionals in their interpretation of TTWB and PWB, however there was a wide range of responses. There was a significant difference between the predicted %TBW and the actual values demonstrated by the ‘educated patient’ (mean difference 4.8 (TTWB) and 22.9 (PWB)).ConclusionHealthcare professionals vary greatly in their interpretation of the terms TTWB and PWB. Therefore, for a consistency in rehabilitation delivery the terms should not be used in isolation without a further descriptor. Static measures of weight application are lower than people think they are applying. We encourage the use of loading practice with a scale to reassure and educate patients.
