I recently underwent hip replacement surgery and have started my rehabilitation period, which will last for three weeks. After this, I will begin gradual training to regain motor function, expected to take about three months. I inquired about the recommended time before resuming scuba and freediving activities, considering my role as a scuba, freediving, and technical instructor/trainer.

ANSWER FROM DAN EXPERTS

[vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern”][vc_column el_class=”page-text”][vc_column_text]In these cases, resumption of diving is generally possible, especially if recovery and functional recovery are rapid and effective. The only caution is to allow sufficient time for proper and complete osseointegration of the prosthesis to ensure that it will hold. In general, the recommended waiting period is at least 6 months, but this may vary depending on the opinion of the treating orthopaedic surgeon regarding the surgical result and the estimation of full functional recovery without significant limitations, even in the case of intensive use of the limb and physical exercise. Once you have regained full functional capacity, we recommend that you start diving with a low decompression load, at least initially. In fact, there must be fully functional recovery even in situations of stress and intensive use of the limb; finning causes considerable stress, with orthogonal leverage and axial torsion mechanisms, so it will be important to determine the optimal functional recovery.

We recommend that you follow low bubble production profiles:

  • When possible avoid dives with mandatory decompression stops;
  • Avoid repetitive dives as much as possible or, if you want to make them, respect sufficient surface intervals (not less than 3 hours, preferably more); in any case, repetitive dives should be shallower and more conservative;
  • limit your bottom time to a maximum of 70% of the No Decompression Dive Time indicated by your computer when you reach the maximum expected depth, or as indicated in the table; if you are using conservative factors, it is a good idea to read your computer’s manual carefully and determine which setting corresponds to the recommended bottom time suggestion;
  • Conduct the dive by immediately reaching the maximum planned ascent, avoiding yo-yo profiles (continuous ascents and descents), respecting the ascent speed recommended by the dive computer/tablet, and making the safety stop with good buoyancy control. Ensure that you ascend slowly to the surface from the safety stop to the surface;
  • if your computer allows more advanced settings, such as Gradient Factor, set GF High not higher than 80. Caution, only use this setting if you fully understand how it works and how it will affect your planned stops. If in doubt, consult a qualified instructor or contact us;
  • if possible, use enriched air mixes with computer settings or use tables set for compressed air, if compatible with the type of dive (note maximum PO2 and time limits);

Remember that diving deeper than 25 metres (80 fsw) is associated with greater bubble production and an increased risk of decompression sickness. It is always advisable to have a good general fitness check by a diving and hyperbaric specialist before resuming activity after a long period of illness/convalescence.[/vc_column_text][/vc_column][/vc_row]
