The clavicular head of pectoralis major musculocutaneous free flap.

A new free flap is described based on the deltoid vessels of the acromiothoracic axis. The flap is comprised of the clavicular head of pectoralis major muscle with overlying skin. It is also possible to harvest vascularised clavicular bone with the flap. The vascular anatomy is reviewed and the technique of raising the flap described. Its clinical application is illustrated with five cases. Four of these were intra-oral reconstructions and the fifth a composite osteo-musculocutaneous flap to a lower limb following trauma.

Observations on dermal blood flow as reflected by technetium-99m pertechnetate clearance.

Skin blood flow as reflected by the clearance rate of intradermal injections of Technetium-99m (99mTc) was studied in the skin of human volunteers and in a variety of clinical situations. In volunteers comparisons between the effect on clearance following intradermal injections of either lignocaine or lignocaine/adrenaline showed that the latter resulted in a dramatic reduction in the clearance rate of the technetium isotope and that such clearance curves exhibited no fast component. Clinical studies in grossly ischaemic skin revealed a similar absence of the fast component of isotope clearance and this was also the case for healed split thickness skin grafts. The dermal isotope clearance was also used in pedicle skin flaps both before and after clamping the axial pedicle in order to derive clearance ratios which would reflect the degree of neovascularisation to the flap. These preliminary observations suggest that the technique is safe, and easy to use in many clinical circumstances. We consider that it offers a valuable method by which changes in dermal blood flow may be quantified, when simultaneous control areas of isotope clearance are also studied. Suggestions are made for further avenues of study.

A review of five years experience of digital replantation.

A five year experience of digital replantation is reviewed. The crude survival rate of 50% is lower than that reported in other comparable series and emphasis is placed on the reasons for failure and implication that they may have on future policy.

Lengthening of a short traumatic femoral stump.

A case is reported in which a severe open injury of the thigh eventually required amputation of the lower limb. Lengthening of the short proximal femoral stump was achieved by turning over a flap comprising bone and soft tissue, with sensation, from the ipsilateral leg.

Lower limb salvage using an extended free radial forearm flap.

A case is reported of an unusual double injury, in which a lower limb salvage procedure employed a free radial forearm flap from an amputated upper limb. The use of amputated parts for salvage procedures is well documented but none has previously involved a free forearm flap. This clinical case shows that the entire forearm and hand skin can be adequately perfused on the radial artery along with the superficial palmar arch.

Free vascularized fibular graft to reconstruct early a traumatic humeral defect.

A case is reported in which a free, vascularized fibular graft was used to reconstruct early a traumatic 16-cm defect in a humerus. A description of a cast-brace used postoperatively is included. A brief review is presented of the literature with respect to the use of free vascularized fibular graft for defects in the upper extremity.

Birmingham Medical Research Expeditionary Society 1977 Expedition: Psychological aspects of acute mountain sickness.

In order to assess the importance of personality and expectations in the development of Acute Mountain Sickness (AMS), 3 standard personality questionnaires and a Mountain Sickness Anticipation Questionnaire were completed by all of the 17 BMRES expedition members before their departure for the Himalayas. AMS could not be predicted with these tests and its occurrence, when assessed either by clinical interview or by peer review, bore no significant relationship to personality. For comparison daily self-assessment of the signs and symptoms of AMS were also conducted throughout the expedition, using graduated and graphic rating scales. The results were found to be unreliable and dependent upon personality factors. These findings have implications for those assessing others at high altitude.

Student views on continuous assessment at Birmingham University Medical School.

Student opinion on the system of continuous assessment used at Birmingham Medical School was sampled by distributing questionnaires to 621 students in the first four years of the course; 482 questionnaires (78%) were returned. Many comments and criticisms of the system were received but the vast majority of students (92%) said they preferred the present style of assessment to conventional final examinations. These criticisms are discussed and recommendations are made to improve the existing scheme.
