ABSTRACT
Hallux rigidus is a disabling problem especially in younger patients. Open cheilectomy or exostosectomy for treatment has been reported with satisfactory results. Analysis of a series of 15 patients who underwent arthroscopic cheilectomy for hallux rigidus has shown very satisfactory and encouraging early results without any recurrence or any need of revision surgery. This has provided rapid recovery and rehabilitation as well as maintained the pain relief with good metatarso-phalangeal joint power and motion.

Eighty-seven feet have been reviewed after arthrodesis of the first metatarsophalangeal joint stabilised by chromic catgut. Radiological union was present in 90% of patients at the mean review time of six years. Twenty-four patients had significant metatarsalgia before operation and only two failed to improve afterwards. Excellent or good subjective results were reported in 94% of patients at review. Chromic catgut is advocated as a simple and effective method of stabilising an arthrodesis of the first metatarsophalangeal joint.

Arthroscopic operation was performed on 105 patients and partial meniscectomy on 72 of them. The average postoperative stay in hospital was 1.4 days and the average time taken to return to work was 16 days. In 50 sportsmen the average return to strenuous sport was 33 days.

The structure of human serum low density lipoprotein has been investigated, as a function of temperature, by measurement of permittivity. Statistical analysis of the dielectric data reveals a transition at around the temperature of the human body. This may be associated with a structural change in the interior of the molecule.

The relative permittivity of aqueous solutions of human serum low density lipoprotein (LDL) and partially trypsin digested lipoprotein (T-LDL) has been determined for various concentrations at 20 degrees C over the frequency range 0.15-100 MHz. Comparison of the dielectric dispersion curves for the digested lipoprotein with those for the native preparation revealed a larger low-frequency dielectric increment, which may be attributed to an increase in the number of counterions moving over the surface of the molecule. An explanation of this observation is an elevation of 70% in the net negative charge on the surface of the trypsin-treated particle as compared to its native counterpart.
