Anatomical Classification

Vaginal  Accumulation in the tunica vaginalis that doesn’t extend up the cord

Congenital  Proximal part of processus has not obliterated and the sac communicates directly ¯c the peritoneum.

Infantile  Processus is obliterated at the deep ring but still extends up the cord

Hydrocele of the Cord  Fluid accumulates around the ductus deferens.  Can be hard to distinguish from an inguinal hernia as it may extend proximal to the superficial ring.  Testicular traction will pull it inferiorly (cf. inguinal hernia)

Aetiological Classification

Primary  Caused by a patent processus vaginalis  Commonest type  Young men, large, tense

Secondary  Vaginal type can be caused by a variety of pathologies . Testicular tumours . Epididymo-orchitis . Trauma . Torsion

Cemented: e.g. Thompson Preventing DVT  Recommended by NICE  DVT is commonest complication of THR  Peak incidence @ 5-10d post-op Uncemented: e.g. Austin-Moore  Easier to revise (may be useful in younger pts.) Pre-Op  TED stocking  Aggressive optimisation: esp. hydration Techniques  Stop OCP

Posterior Approach Intra-Op  Access joint and capsule posteriorly, reflecting of the  Minimise length of surgery short external rotators.  Using pneumatic compression boots  Gives good access  May have higher dislocation rate Post-Op  Sciatic N. may be injured → foot drop  LMWH: also rivaroxaban and dabigatran  Early mobilisation Anterolateral Approach  Good analgesia  Incision over greater trochanter, dividing fascia lata.  Physio  Abductors are reflected to access joint capsule.  Adequate hydration  May have lower dislocation risk  Sup. Gluteal N. may be injured → Trendelenberg gait

Advantages  Metal-on-metal bearings wear less  Larger head → ↓ dislocation / ↑ stability  Preserve bone stock making revision easier

Disadvantages  Cobalt and chromium metal ion release may cause pathology (e.g. leukaemia)  Risk of NOF # if mal-positioned

Indications  May be used in young (<65), active people who are expected to outlive the replacement.
